整関数の極値
整関数の極値
問題≪$3$ 次関数のグラフの対称性≫
$a,$ $b,$ $c,$ $d$ $(a \neq 0)$を実数とする. $3$ 次関数 $f(x) = ax^3+bx^2+cx+d$ とそのグラフ $C:y = f(x)$ 上の点 $\mathrm M\left( -\dfrac{b}{3a},f\left( -\dfrac{b}{3a}\right)\right)$ について, 次のことを示せ.
(A)
$C$ は点 $\mathrm M$ に関して対称である.
(B)
$f(x)$ が $x = \alpha$ で極大値, $x = \beta$ で極小値をとるとき, $2$ 点 $\mathrm A(\alpha,f(\alpha )),$ $\mathrm B(\beta,f(\beta ))$ を結ぶ線分の中点は $\mathrm M$ に一致する.
解答例
$p = -\dfrac{b}{3a},$ $q = f(p)$ とおく.
(A)
このとき, $C$ を $x$ 軸方向に $-p,$ $y$ 軸方向に $-q$ だけ平行移動した曲線 $C_0$ の方程式は, \[ y+q = f(x+p)\] つまり \begin{align*} y &= f(x+p)-q \\ &= a(x+p)^3+b(x+p)^2+c(x+p)+d-q \\ &= ax^3+(3ap+b)x^2+(3ap^2+2bp+c)x \\ &\qquad +(ap^3+bp^2+cp+d)-q \\ &= ax^3+(3ap^2+2bp+c)x \end{align*} である. 右辺は $x$ の奇関数であるから, $C_0$ は原点に関して対称である. $C$ は, $C_0$ を $x$ 軸方向に $p,$ $y$ 軸方向に $q$ だけ平行移動した曲線であるから, 点 $\mathrm M(p,q)$ に関して対称である.
(B)
平行移動しても線分とその中点の関係は変わらないから, $\mathrm M = \mathrm O$ の場合に \[\frac{\alpha +\beta}{2} = 0\ \cdots [1], \quad \frac{f(\alpha )+f(\beta )}{2} = 0\ \cdots [2]\] を示せば十分である. このとき, $p = 0,$ $q = f(p) = f(0) = 0$ から, $b = d = 0$ であり, \[ f(x) = ax^3+cx, \quad f'(x) = 3ax^2+c\] である. $\alpha,$ $\beta$ は $f'(x) = 0$ の解であるから, 解と係数の関係により, \[\alpha +\beta = 0\] が成り立ち, $[1]$ が従う. さらに, \begin{align*} \frac{f(\alpha )+f(\beta )}{2} &= \frac{a\alpha ^3+c\alpha +a\beta ^3+c\beta}{2} \\ &= \frac{a(\alpha ^3+\beta ^3)+c(\alpha +\beta )}{2} \\ &= \frac{a(\alpha\!+\!\beta )(\alpha ^2\!-\!\alpha\beta\!+\!\beta ^2)\!+\!c(\alpha\!+\!\beta )}{2} \\ &= 0 \quad \cdots [2] \end{align*} が成り立つ. 以上から, 線分 $\mathrm{AB}$ の中点は $\mathrm M$ に一致する.
背景
• 一般に, 実数値関数 $f(x)$ に対して, \begin{align*} &y = f(x)\text{ が点 }(p,q)\text{ に関して対称} \\ &\iff y+q = f(x+p)\text{ が原点に関して対称} \\ &\iff f(-x+p)-q = -f(x+p)+q \\ &\iff f(x+p)-q\text{ が奇関数} \end{align*} が成り立つ.
• 一般に, 実数値関数 $f(x)$ は偶関数 $\dfrac{f(x)+f(-x)}{2}$ と奇関数 $\dfrac{f(x)-f(-x)}{2}$ の和として \[ f(x) = \frac{f(x)+f(-x)}{2}+\frac{f(x)-f(-x)}{2}\] と一意的に表すことができる. 多項式関数の場合には, 偶関数の部分が偶数次の項の和, 奇関数の部分が奇数次の項の和となる. よって, 多項式関数が偶関数のとき偶数次の項の係数は $0$ であり, 奇関数のとき奇数次の項の係数は $0$ である.
問題≪$4$ 次関数のグラフの対称性≫
$a,$ $b,$ $c,$ $d,$ $e$ $(a \neq 0)$を実数とする. $4$ 次関数 $f(x) = ax^4+bx^3+cx^2+dx+e$ とそのグラフ $C:y = f(x)$ について, 次の問いに答えよ.
(A)
$C$ が $y$ 軸に平行な直線 $x = p$ に関して対称であるとする. このとき, $a,$ $b,$ $c,$ $d,$ $e$ を用いて $p$ を表し, $a,$ $b,$ $c,$ $d,$ $e$ の関係式を求めよ.
(B)
$f(x)$ がある実数 $x = p$ に関して対称な $2$ 点において等しい極値をとるならば, $C$ は直線 $x = p$ に関して対称であり, $f(x)$ は $x = p$ においても極値をとることを示せ.
解答例
(A)
$C$ を $x$ 軸方向に $-p$ だけ平行移動した曲線の方程式は, \[ y = a(x\!+\!p)^4\!+\!b(x\!+\!p)^3\!+\!c(x\!+\!p)^2\!+\!d(x\!+\!p)\!+\!e\] である. この曲線は $y$ 軸に関して対称であり, 右辺は偶関数であるから, $3$ 次, $1$ 次の項の係数は $0$ であり, \begin{align*} 4ap+b &= 0 \quad \cdots [1], \\ 4ap^3+3bp^2+2cp+d &= 0 \quad \cdots [2] \end{align*} が成り立つ. $[1]$ から, \[ p = -\frac{b}{4a}\] が得られる. これを $[2]$ に代入すると \begin{align*} -\frac{b^3}{16a^2}+\frac{3b^3}{16a^2}-\frac{bc}{2a}+d &= 0 \\ \frac{b^3}{8a^2}-\frac{bc}{2a}+d &= 0 \end{align*} となるから, 求める関係式は \[ b^3-4abc+8a^2d = 0\] である.
(B)
平行移動を考えることにより, $p = 0$ の場合を示せばよい. $f(x)$ が $x = \pm\alpha$ $(\alpha > 0)$ において等しい極値をとるとする. このとき, $f(\alpha ) = f(-\alpha )$ つまり \[ a\alpha ^4\!+\!b\alpha ^3\!+\!c\alpha ^2\!+\!d\alpha\!+\!e = a\alpha ^4\!-\!b\alpha ^3\!+\!c\alpha ^2\!-\!d\alpha\!+\!e\] であるから, \begin{align*} 2b\alpha ^3+2d\alpha &= 0 \\ b\alpha ^2+d &= 0 \quad \cdots [1] \end{align*} が成り立つ. また, \[ f'(\pm\alpha ) = 0\] であり, \[ f'(x) = 4ax^3+3bx^2+2cx+d\] であるから, \begin{align*} 4a\alpha ^3+3b\alpha ^2+2c\alpha +d &= 0, \quad \cdots [2] \\ -4a\alpha ^3+3b\alpha ^2-2c\alpha +d &= 0 \quad \cdots [3] \end{align*} が成り立つ. $[2]-[3]$ から \begin{align*} 8a\alpha ^3+4c\alpha &= 0 \\ 2a\alpha ^2+c &= 0 \end{align*} が成り立つ. これを $[2]$ つまり \[ 2\alpha (2a\alpha ^2+c)+3b\alpha ^2+d = 0\] に代入すると, \[ 3b\alpha ^2+d = 0 \quad \cdots [4]\] が得られる. よって, $[1],$ $[4]$ から, \[ b = d = 0\] が成り立つ. したがって, $f(x)$ は偶関数であるから, $y = f(x)$ は直線 $x = 0$ に関して対称である. さらに, このとき \[ f'(x) = 4ax^3+2cx = 2x(2ax^2+c)\] であるから, $f'(x) = 0$ は $3$ つの実数解 $x = 0,$ $\pm\alpha$ をもつ. $f'(x)$ の符号は $x = 0,$ $\pm\alpha$ の前後で入れ替わるから, $f(x)$ は $x = 0$ でも極値をとる. これで, 題意が示された.
背景
一般に, 実数値関数 $f(x)$ に対して, \begin{align*} &y = f(x)\text{ が直線 }x = p\text{ に関して対称} \\ &\iff y = f(x+p)\text{ が }y\text{ 軸に関して対称} \\ &\iff f(-x+p) = f(x+p) \\ &\iff f(x+p)\text{ が偶関数} \end{align*} が成り立つ.

Using Perl With XML (part 2)
They say there’s more than one way to skin a cat – and that’s twice as true when you’re a Perl developer. In this concluding article on XML parsing with Perl, find out how the XML::DOM package provides an alternative technique for manipulating XML elements and attributes, and compare the two approaches to see which one works best for you.
In the first part of this article, I said that there were two approaches to parsing an XML document. The event-based SAX approach is one; the other uses the DOM, or Document Object Model, to build a tree representation of the XML data structures in the document, and then offers built-in methods to navigate through this tree. Once a particular node has been reached, built-in methods can be used to obtain the value of the node, and use it within the script.
Over the next few pages, I’m going to take a look at a Perl package that supports this tree-based approach. I’ll also attempt to duplicate the previous examples, marking up books and recipes with HTML tags, in order to demonstrate how either technique can be used to achieve the same result. Finally, I’ll briefly discuss the pros and cons of the SAX and DOM approaches, and point you to some links for your further education.
Let’s get started, shall we?{mospagebreak title=Meet Joe Cool} Perl comes with a DOM parser based on the expat library created by James Clark; it’s implemented as a Perl package named XML::DOM, and currently maintained by T. J. Mather. If you don’t already have it, you should download and install it before proceeding further; you can get a copy from CPAN (http://www.cpan.org/).
This DOM parser works by reading an XML document and creating objects to represent the different parts of that document. Each of these objects comes with specific methods and properties, which can be used to manipulate and access information about it. Thus, the entire XML document is represented as a “tree” of these objects, with the DOM parser providing a simple API to move between the different branches of the tree.
The parser itself supports all the different structures typically found in an XML document – elements, attributes, namespaces, entities, notations et al – but our focus here will be primarily on elements and the data contained within them. If you’re interested in the more arcane aspects of XML – as you will have to be to do anything complicated with the language – the XML::DOM package comes with some truly excellent documentation, which gets installed when you install the package. Make it your friend, and you’ll find things considerably easier.
Let’s start things off with a simple example:
#!/usr/bin/perl # create an XML-compliant string $xml = “<?xml version=”1.0″?><me><name>Joe Cool</name><age>24</age><sex>male</sex></me>”; # include package use XML::DOM; # instantiate parser $xp = new XML::DOM::Parser(); # parse and create tree $doc = $xp->parse($xml); # print tree as string print $doc->toString(); # end
In this case, a new instance of the parser is created and assigned to the variable $xp. This object instance can now be used to parse the XML data via its parse() function:
# instantiate parser $xp = new XML::DOM::Parser(); # parse and create tree $doc = $xp->parse($xml);
You’ll remember the parse() function from the first part of this article – it was used by the SAX parser to parse a string. When you think about it, this isn’t really all that remarkable – the XML::DOM package is built on top of the XML::Parser package, and therefore inherits many of the latter’s methods.
With that in mind, it follows that the DOM parser should also be able to read an XML file directly, simply by using the parsefile() method, instead of the parse() method:
#!/usr/bin/perl # XML file $file = “me.xml”; # include package use XML::DOM; # instantiate parser $xp = new XML::DOM::Parser(); # parse and create tree $doc = $xp->parsefile($file); # print tree as string print $doc->toString(); # end
The results of successfully parsing an XML document – whether string or file – is an object representation of the XML document (actually, an instance of the Document class). In the example above, this object is called $doc.
# instantiate parser $xp = new XML::DOM::Parser(); # parse and create tree $doc = $xp->parsefile($file);
This Document object comes with a bunch of interesting methods – and one of the more useful ones is the toString() method, which returns the current document tree as a string. In the examples above, I’ve used this method to print the entire document to the console.
# print tree as string print $doc->toString();
It should be noted that this isn’t all that great an example of how to use the toString() method. Most often, this method is used during dynamic XML tree generation, when an XML tree is constructed in memory from a database or elsewhere. In such situations, the toString() method comes in handy to write the final XML tree to a file or send it to a parser for further processing.{mospagebreak title=Parents And Their Children} The Document object comes with another useful method, one which enables you to gain access to information about the document’s XML version and character encoding. It’s called the getXMLDecl() method, and it returns yet another object, this one representing the standard XML declaration that appears at the top of every XML document. Take a look:
#!/usr/bin/perl # create an XML-compliant string $xml = “<?xml version=”1.0″ encoding=”utf-8″?><me><name>Joe Cool</name><age>24</age><sex>male</sex></me>”; # include package use XML::DOM; # instantiate parser $xp = new XML::DOM::Parser(); # parse and create tree $doc = $xp->parse($xml); # get XML PI $decl = $doc->getXMLDecl(); # get XML version print $decl->getVersion(); # get encoding print $decl->getEncoding(); # get whether standalone print $decl->getStandalone(); # end
As you can see, the newly-created XMLDecl object comes with a bunch of object methods of its own. These methods provide a simple way to access the document’s XML version, character encoding and status.
Using the Document object, it’s also possible to obtain references to other nodes in the XML tree, and manipulate them using standard methods. Since the entire document is represented as a tree, the first step is always to obtain a reference to the tree root, or the outermost document element, and use this a stepping stone to other, deeper branches. Consider the following example, which demonstrates how to do this:
#!/usr/bin/perl # create an XML-compliant string $xml = “<?xml version=”1.0″?><me><name>Joe Cool</name><age>24</age><sex>male</sex></me>”; # include package use XML::DOM; # instantiate parser $xp = new XML::DOM::Parser(); # parse and create tree $doc = $xp->parse($xml); # get root node “me” $root = $doc->getDocumentElement(); # end
An option here would be to use the getChildNodes() method, which is a common method available to every single node in the document tree. The following code snippet is identical to the one above:
#!/usr/bin/perl # create an XML-compliant string $xml = “<?xml version=”1.0″?><me><name>Joe Cool</name><age>24</age><sex>male</sex></me>”; # include package use XML::DOM; # instantiate parser $xp = new XML::DOM::Parser(); # parse and create tree $doc = $xp->parse($xml); # get root node “me” @children = $doc->getChildNodes(); $root = $children[0]; # end
Note that the getChildNodes() method returns an array of nodes under the current node; each of these nodes is again an object instance of the Node class, and comes with methods to access the node name, type and content. Let’s look at that next.{mospagebreak title=What’s In A Name?} Once you’ve obtained a reference to a node, a number of other methods become available to help you obtain the name and value of that node, as well as references to parent and child nodes. Take a look:
#!/usr/bin/perl # create an XML-compliant string $xml = “<?xml version=”1.0″?><me><name>Joe Cool</name><age>24</age><sex>male</sex></me>”; # include package use XML::DOM; # instantiate parser $xp = new XML::DOM::Parser(); # parse and create tree $doc = $xp->parse($xml); # get root node $root = $doc->getDocumentElement(); # get name of root node # returns “me” print $root->getNodeName(); # get children as array @children = $root->getChildNodes(); # this is the “name” element under “me” # I could also have used $root->getFirstChild() to get here $firstChild = $children[0]; # returns “name” print $firstChild->getNodeName(); # returns “1” print $firstChild->getNodeType(); # now to access the value of the text node under “name” $text = $firstChild->getFirstChild(); # returns “Joe Cool” print $text->getData(); # returns “#text” print $text->getNodeName(); # returns “3” print $text->getNodeType(); # go back up the tree # start from the “name” element and get its parent $parent = $firstChild->getParentNode(); # check the name – it should be “me” # yes it is! print $parent->getNodeName(); # end
As you can see, the getNodeName() and getNodeType() methods provide access to basic information about the node currently under examination. The children of this node can be obtained with the getChildNodes() method previously discussed, and node parents can be obtained with the getParentNode() method. It’s fairly simple, and – once you play with it a little – you’ll get the hang of how it works.
A quick note on the getNodeType() method above: every node is of a specific type, and this property returns a numeric code corresponding to the type. A complete list of defined types is available in the Perl documentation for the XML::DOM package.
Note also that the text within an element’s opening and closing tags is treated as a child node of the corresponding element node, and is returned as an object. This object comes with a getData() method, which returns the actual content nested within the element’s opening and closing tags. You’ll see this again in a few pages.{mospagebreak title=Welcome To The Human Race} Just as it’s possible to access elements and their content, it’s also possible to access element attributes and their values. The getAttributes() method of the Node object provides access to a list of all available attributes, and the getNamedItem() and getValue() methods make it possible to access specific attributes and their values. Take a look at a demonstration of how it all works:
#!/usr/bin/perl # create an XML-compliant string $xml = “<?xml version=”1.0″?><me species=”human”><name>Joe Cool</name><age>24</age><sex>male</sex></me>”; # include package use XML::DOM; # instantiate parser $xp = new XML::DOM::Parser(); # parse and create tree $doc = $xp->parse($xml); # get root node (Node object) $root = $doc->getDocumentElement(); # get attributes (NamedNodeMap object) $attribs = $root->getAttributes(); # get specific attribute (Attr object) $species = $attribs->getNamedItem(“species”); # get value of attribute # returns “human” print $species->getValue(); # end
Getting to an attribute value is a little more complicated than getting to an element. But hey – no gain without pain, right?{mospagebreak title=Building A Library} Using this information, it’s pretty easy to re-create our first example using the DOM parser. Here’s the XML data,
<?xml version=”1.0″?> <library> <book> <title>Dreamcatcher</title> <author>Stephen King</author> <genre>Horror</genre> <pages>899</pages> <price>23.99</price> <rating>5</rating> </book> <book> <title>Mystic River</title> <author>Dennis Lehane</author> <genre>Thriller</genre> <pages>390</pages> <price>17.49</price> <rating>4</rating> </book> <book> <title>The Lord Of The Rings</title> <author>J. R. R. Tolkien</author> <genre>Fantasy</genre> <pages>3489</pages> <price>10.99</price> <rating>5</rating> </book> </library>
and here’s the script which does all the work.
#!/usr/bin/perl # XML file $file = “library.xml”; # array of ratings @ratings = (“Words fail me!”, “Terrible”, “Bad”, “Indifferent”, “Good”, “Excellent”); # include package use XML::DOM; # instantiate parser $xp = new XML::DOM::Parser(); # parse and create tree $doc = $xp->parsefile($file); # set up HTML page print “Content-Type: text/htmlnn”; print “<html><head></head><body>”; print “<h2>The Library</h2>”; print “<table border=1 cellspacing=1 cellpadding=5> <tr> <td align=center>Title</td> <td align=center>Author</td> <td align=center>Price</td> <td align=center>User Rating</td> </tr>”; # get root node $root = $doc->getDocumentElement(); # get children @books = $root->getChildNodes(); # iterate through book list foreach $node (@books) { print “<tr>”; # if element node if ($node->getNodeType() == 1) { # get children # this is the “title”, “author”… level @children = $node->getChildNodes(); # iterate through child nodes foreach $item (@children) { # check element name if (lc($item->getNodeName) eq “title”) { # print text node contents under this element print “<td><i>” . $item->getFirstChild()->getData . “</i></td>”; } elsif (lc($item->getNodeName) eq “author”) { print “<td>” . $item->getFirstChild()->getData . “</td>”; } elsif (lc($item->getNodeName) eq “price”) { print “<td>$” . $item->getFirstChild()->getData . “</td>”; } elsif (lc($item->getNodeName) eq “rating”) { $num = $item->getFirstChild()->getData; print “<td>” . $ratings[$num] . “</td>”; } } } print “</tr>”; } print “</table></body></html>”; # end
This may appear complex, but it isn’t really all that hard to understand. I’ve first obtained a reference to the root of the document tree, $root, and then to the children of that root node; these children are returned as a regular Perl array. I’ve then used a “foreach” loop to iterate through the array, navigate to the next level, and print the content found in the nodes, with appropriate formatting. The numerous “if” statements you see are needed to check the name of each node and then add appropriate HTML formatting to it.
As explained earlier, the data itself is treated as a child text node of the corresponding element node. Therefore, whenever I find an element node, I’ve used the node’s getFirstChild() method to access the text node under it, and the getData() method to extract the data from that text node.
Here’s what it looks like:
{mospagebreak title=Anyone For Chicken?} I can do the same thing with the second example as well. However, since there are quite a few levels to the document tree, I’ve decided to use a recursive function to iterate through the tree, rather than a series of “if” statements.
Here’s the XML file,
<?xml version=”1.0″?> <recipe> <name>Chicken Tikka</name> <author>Anonymous</author> <date>1 June 1999</date> <ingredients> <item> <desc>Boneless chicken breasts</desc> <quantity>2</quantity> </item> <item> <desc>Chopped onions</desc> <quantity>2</quantity> </item> <item> <desc>Ginger</desc> <quantity>1 tsp</quantity> </item> <item> <desc>Garlic</desc> <quantity>1 tsp</quantity> </item> <item> <desc>Red chili powder</desc> <quantity>1 tsp</quantity> </item> <item> <desc>Coriander seeds</desc> <quantity>1 tsp</quantity> </item> <item> <desc>Lime juice</desc> <quantity>2 tbsp</quantity> </item> <item> <desc>Butter</desc> <quantity>1 tbsp</quantity> </item> </ingredients> <servings> 3 </servings> <process> <step>Cut chicken into cubes, wash and apply lime juice and salt</step> <step>Add ginger, garlic, chili, coriander and lime juice in a separate bowl</step> <step>Mix well, and add chicken to marinate for 3-4 hours</step> <step>Place chicken pieces on skewers and barbeque</step> <step>Remove, apply butter, and barbeque again until meat is tender</step> <step>Garnish with lemon and chopped onions</step> </process> </recipe>
and here’s the script which parses it.
#!/usr/bin/perl # XML file $file = “recipe.xml”; # hash of tag names mapped to HTML markup # “recipe” => start a new block # “name” => in bold # “ingredients” => unordered list # “desc” => list items # “process” => ordered list # “step” => list items %startTags = ( “name” => “<font size=+2>”, “date” => “<i>(“, “author” => “<b>”, “servings” => “<i>Serves “, “ingredients” => “<h3>Ingredients:</h3><ul>”, “desc” => “<li>”, “quantity” => “(“, “process” => “<h3>Preparation:</h3><ol>”, “step” => “<li>” ); # close tags opened above %endTags = ( “name” => “</font><br>”, “date” => “)</i>”, “author” => “</b>”, “ingredients” => “</ul>”, “quantity” => “)”, “servings” => “</i>”, “process” => “</ol>” ); # this function accepts an array of nodes as argument, # iterates through it and prints HTML markup for each tag it finds. # for each node in the array, it then gets an array of the node’s children, and # calls itself again with the array as argument (recursion) sub printData() { my (@nodeCollection) = @_; foreach $node (@nodeCollection) { print $startTags{$node->getNodeName()}; print $node->getFirstChild()->getData(); my @children = &getChildren($node); printData(@children); print $endTags{$node->getNodeName()}; } } # this function accepts a node # and returns all the element nodes under it (its children) # as an array sub getChildren() { my ($node) = @_; # get children of this node my @temp = $node->getChildNodes(); my $count = 0; my @collection; # iterate through children foreach $item (@temp) { # if this is an element # (need this to strip out text nodes containing whitespace) if ($item->getNodeType() == 1) { # add it to the @collection array $collection[$count] = $item; $count++; } } # return node collection return @collection; } use XML::DOM; # instantiate parser $xp = new XML::DOM::Parser(); # parse and create tree $doc = $xp->parsefile($file); # send standard header to browser print “Content-Type: text/htmlnn”; # print HTML header print “<html><head></head><body><hr>”; # get root node $root = $doc->getDocumentElement(); # get children @children = &getChildren($root); # run a recursive function starting here &printData(@children); print “</table></body></html>”; # end
In this case, I’ve utilized a slightly different method to mark up the XML. I’ve first initialized a couple of hashes to map XML tags to corresponding HTML markup, in much the same manner as I did last time. Next, I’ve used DOM functions to obtain a reference to the first set of child nodes in the DOM tree.
This initial array of child nodes is used to “seed” my printData() function, a recursive function which takes an array of child nodes, matches their tag names to values in the associative arrays, and outputs the corresponding HTML markup to the browser. It also obtains a reference to the next set of child nodes, via the getChildren() function, and calls itself with the new node collection as argument.
By using this recursive function, I’ve managed to substantially reduce the number of “if” conditional statements in my script; the code is now easier to read, and also structured more logically.
Here’s what it looks like:
{mospagebreak title=Conclusions…} As you can see, you can parse a document using either DOM or SAX, and achieve the same result. The difference is that the DOM parser is a little slower, since it has to build a complete tree of the XML data, whereas the SAX parser is faster, since it’s calling a function each time it encounters a specific tag type. You should experiment with both methods to see which one works better for you.
There’s another important difference between the two techniques. The SAX approach is event-centric – as the parser travels through the document, it executes specific functions depending on what it finds. Additionally, the SAX approach is sequential – tags are parsed one after the other, in the sequence in which they appear. Both these features add to the speed of the parser; however, they also limit its flexibility in quickly accessing any node of the DOM tree.
As opposed to this, the DOM approach builds a complete tree of the document in memory, making it possible to easily move from one node to another (in a non-sequential manner). Since the parser has the additional overhead of maintaining the tree structure in memory, speed is an issue here; however, navigation between the various “branches” of the tree is easier. Since the approach is not dependent on events, developers need to use the exposed methods and attributes of the various DOM objects to process the XML data.{mospagebreak title=…And Links} That just about concludes this little tour of parsing XML data with Perl. I’ve tried to keep it as simple as possible, and there are numerous aspects of XML I haven’t covered here. If you’re interested in learning more about XML and XSL, you should visit the following links:
The XML specification, at http://www.w3.org/TR/2000/REC-xml-20001006
The XSLT specification, at http://www.w3.org/TR/xslt.html
The SAX project, at http://www.saxproject.org/
The W3C’s DOM specification, at http://www.w3.org/DOM/
A number of developers have built and released Perl packages to handle XML data – if you’re ever on a tight deadline, using these packages might save you some development time. Take a look at the following links for more information:
CPAN, at http://www.cpan.org/
And that’s just about all for the moment. I hope you found this interesting, and that it helped to make the road ahead a little clearer. Till next time, stay healthy!

The importance of user testing in app development
January 7, 2023 | Heather Stugen
User testing is a crucial step in the app development process that should not be overlooked. It allows developers to gather valuable feedback from real users, identify any problems or usability issues, and make necessary improvements before launching the app. In this blog post, we’ll explore the importance of user testing in app development and how it can lead to a better, more successful app.
First, let’s define user testing. It is the process of evaluating a product or service by testing it with representative users. In the context of app development, user testing involves having a group of users try out the app and provide feedback on its functionality, usability, and overall user experience. This feedback can come in the form of surveys, interviews, focus groups, or simply observing users as they interact with the app.
So why is user testing important in app development? Here are a few key reasons:
1. User testing helps identify problems and usability issues. Even the most well-designed app can have problems that may not be immediately obvious to developers. User testing allows developers to see how real users interact with the app and identify any issues or problems that need to be addressed. This can include everything from bugs and glitches to usability issues and user frustration. By identifying and fixing these issues early on, developers can save time and resources in the long run.
2. User testing helps improve the user experience. User testing allows developers to get a better understanding of how users interact with the app and what they like or dislike about it. This can help developers make necessary improvements to the user experience, such as simplifying navigation, improving the layout, or adding new features that users want. A better user experience leads to higher user satisfaction and can ultimately drive more downloads and engagement.
3. User testing helps validate design decisions. Before user testing, developers may have certain assumptions about how users will interact with the app. User testing allows developers to validate these assumptions and see if they hold up in practice. It can also help developers discover new insights about how users want to use the app and what they need. This information can inform future design decisions and help ensure that the app meets the needs of its target audience.
4. User testing helps build credibility and trust with users. By actively seeking out and incorporating user feedback, developers can show users that they care about their needs and are committed to creating a high-quality app. This can help build credibility and trust with users, which can translate into higher retention and loyalty.
So, how can developers go about user testing their app? Here are a few steps to follow:
1. Define your goals. What do you want to learn from user testing? Do you want to gather feedback on the overall user experience, identify usability issues, or validate certain design decisions? Having clear goals in mind will help guide the user testing process and ensure that you get the most value out of it.
2. Identify your target audience. Who will you be testing your app with? Make sure to select a representative group of users that aligns with your target audience. This could include demographics such as age, gender, location, and profession.
3. Plan your user testing sessions. Decide how you want to conduct user testing, such as through surveys, interviews, focus groups, or simply observing users as they interact with the app. Make sure to provide clear instructions and guidelines for users to follow during the testing process.
4. Gather and analyze feedback. After conducting user testing, it’s important to carefully review and analyze the feedback you received. Look for patterns and trends in the data and use them to inform future design decisions. Make sure to document any issues or problems that users identified and prioritize them for future updates or fixes.

How can I set popup_menu parameters and send them to another page?
by jaffinito34 (Acolyte)
on May 11, 2013 at 18:00 UTC ( #1033141=perlquestion: print w/ replies, xml ) Need Help??
jaffinito34 has asked for the wisdom of the Perl Monks concerning the following question:
I understand to send data to another page, you use:
print start_form( -action=>'results.cgi'); various form stuff.... print end_form;
I would like to be able to take the selected options from popup_menu's as well as a textbox to return information from a database. So I'm going from a search page to a results page. The search page is displaying information from the database, then whatever the user picks as their selection in the popup_menu gets passed to the results page to query the database.
use DBI; use CGI::Cookie; use CGI qw /:standard/; use warnings; #checking if cookie is set, if not redirecting to login my %cookies = CGI::Cookie->fetch; if (! defined $cookies{'authorized'}) { print redirect('login.cgi') } #connecting to DB my $dbh = DBI->connect("dbi:SQLite:dbname=/path/to/database.db","","") +; # getting artist info my $sth = $dbh->prepare('select artistid, name from artist'); $sth->execute; # getting genre info my $sth2 = $dbh->prepare('select genreid, name from genre'); $sth2->execute; #printing header print header, start_html('Database Search'), h2('Select items from the dropdown menus to help filter your results.' +), br,br, end_html; print start_form(-action=>'results.cgi'); end_form; ### THIS CAUSES REDIRECT TO RESULTS WHEN USER HITS SUBMI +T ############################POPUPS###################### #displaying artist dropdown my @artistValues; my %artistLabels; #this push adds to beginning of values, then it gets set to 'Make a se +lection' as the default for the dropdown push (@artistValues, -1); print h4('Please select an artist'); $artistLabels{-1} = "Make a selection"; while (my @row = $sth->fetchrow_array) { #2 columns in DB, first is ID second is NAME my $artistId = $row[0]; my $artistName = $row[1]; push(@artistValues,$artistId); $artistLabels{$artistId} = $artistName; } print popup_menu(-name=>'artist', -values=>\@artistValues, -labels=>\%artistLabels); $userArtist = param('artist'); #displaying genre dropdown my @genreValues; my %genreLabels; push (@genreValues, 'Make a selection'); print br,br; print h4('Please select a genre'); $genreLabels{-1} = "Make a selection"; while (my @row = $sth2->fetchrow_array) { my $genreId = $row[0]; my $genreName = $row[1]; push (@genreValues, $genreName); $genreLabels{$genreId} = $genreId; } print popup_menu(-name=>'genre', -values=>\@genreValues, -lables=>\%genreLabels); $userGenre = param('genre'); print br,br; ###################################################################### +## #displaying trackname textbox print "Track name: ",textfield('trackname'),br,br submit('SEARCH'), $trackName = param('trackname'); while(my @row = $sth->fetchrow_array){ foreach $item (@row){ print "$item "; }print br; } print br,br,br,br,a({href=>'http://www.blablabla.com/logout.cgi'},'Log +out');
When I go to print the parameters ($userArtist, $userGenre, $trackName), only trackname gets printed and I don't see anything for artist or genre. I am not able to find anything online about this, or maybe I'm just unsure how it works, any help is appreciated.

You could use a test results.cgi page to see the name and value of all the parameter sent like this ;
use strict; use CGI qw /:standard/; print header,start_html('results'); print h3("Parameters"); for (param){ print "$_ = ".param($_)."<br/>"; } print end_html;

Re: How can I set popup_menu parameters and send them to another page?
by thewebsi (Beadle) on May 11, 2013 at 20:07 UTC
I'm assuming that this script is the "search" page and the "results" page is where you are printing the parameter values (not shown here).
print start_form(-action=>'results.cgi');
end_form; ### THIS CAUSES REDIRECT TO RESULTS WHEN USER HITS SUBMIT
It looks like this might be the issue: You want to print end_form() (not just run it), and you want to do this at the end of your script (ie, at the end of the form), not here.
Re: How can I set popup_menu parameters and send them to another page?
by Anonymous Monk on May 11, 2013 at 20:22 UTC
#printing header print header, start_html('Database Search'), h2('Select items from the dropdown menus to help filter your results.' +), br,br, end_html;
Why did you output the end_html here? That should be the last item printed, not one of the first items prior to your form.

Proof that e is irrational
By Martin McBride, 2024-06-07
Tags: exponential proof irrational e euler
Categories: exponentials
Euler's number, e, is an important number in mathematics that appears in many contexts.
As an example, here are two important properties of $e$. First, the following simple first-order differential equation applies to many situations from population growth to radioactive decay:
Uses of e
The only non-trivial solution to this equation (we will ignore the trivial solution y = 0) is the exponential function e to the power x:
Uses of e
Second, e is involved in Euler's formula, which is the bedrock of the complex analysis (the study of complex numbers):
Uses of e
If we substitute the value π for θ we get Euler's identity:
Uses of e
This formula puts e at the heart of mathematics. It links what are arguably the three most important constants in mathematics, pi, e and i, in a single formula.
It turns out that e is an irrational number, and in this article, we will look at Fourier's ingenious proof of that.
Fourier's proof
Joseph Fourier's proof is a proof by contradiction. We start by assuming that e is rational, meaning that, for some positive integers a and b we have:
Fourier's proof
We will prove that this leads to a contradiction, and therefore cannot be true. This is a similar approach we saw for the proof that the square root of 2 is irrational, although after this initial step, the two proofs are quite different.
This proof relies on the Maclaurin expansion of the exponential function, given by:
Fourier's proof
We can use this to find an expression for e, simply by setting x equal to 1:
Fourier's proof
Properties of factorials
Before we get into the proof, we will look at a couple of properties of factorials that will be useful later. The factorial of n, of course, is the product of n and every positive integer less than n:
Properties of factorials
There is a special rule that 0! is equal to 1.
Any factorial is divisible by any smaller factorial. For example, 7! is divisible by 4!, because the smallest four terms are identical, so they just cancel out:
Properties of factorials
So in general, if n ≥ m we can write the quotient of the factorials like this:
Properties of factorials
This is always an integer, because each term in the product is an integer. We will use this fact later.
If n < m we get a rational fraction (it is always one divided by an integer):
Properties of factorials
On with the proof
So far we have shown that if e is rational, then the following must be true (where a and b are positive integers):
Fourier's proof
We are, of course, hoping to prove that this equation cannot hold when a and b are positive integers. That will prove that e is irrational.
It will be useful to multiply both sides by b!:
Fourier's proof
Looking at the right-hand side, each term has a denominator that is a factorial, and the factorial becomes larger with each successive term. We can split the terms into two groups - those where the denominator is less than or equal to b! and those where the denominator is greater than b!. All we have done is group the terms, we haven't changed anything:
Fourier's proof
Let's write this as:
Fourier's proof
We can look at the terms one by one. P can be simplified as follows:
Fourier's proof
We have used the fact that b! is equal to b(b-1)!, then cancelled out b top and bottom. Since a is an integer and any factorial is an integer, it follows that P is an integer. As we will see, that is all we need to know about P.
Now on to Q:
Fourier's proof
Every term on the right has the form n!/m! where n ≥ m. We saw earlier that this always evaluates to an integer. This means that Q is the sum of a finite set of integers so Q must be an integer.
So we have shown that if a and b are integers, P and Q must also be integers. And if P is equal to Q plus R, then R must also be an integer.
If we can prove that R is not an integer, we have a contradiction. In that case, P cannot be an integer, so a and b cannot be both integers, so e cannot be rational.
Finalising Fourier's proof
From above, we have:
Fourier's proof
This is an infinite series, so how do we prove it is not integer? There is no obvious way to solve it, but fortunately, Fourier found a clever method to prove that whatever the result is, it cannot an integer.
First, since b is a positive integer, therefore greater than 0, we can say for certain that R > 0.
Can we find an upper bound? Let's expand the first few terms, using the factorial rule we discovered earlier for n!/m! when n < m. The first term is:
Fourier's proof
The second term is:
Fourier's proof
Fourier now uses a clever simplification. Since (b + 2) is greater than (b + 1), if we substitute (b + 1) in the denominator it will make the fraction bigger. So we can say that:
Fourier's proof
Which in turn gives us the result that:
Fourier's proof
The third term is:
Fourier's proof
We can do the same thing, substituting both (b + 2) and (b + 3) with (b + 1) and applying the same logic:
Fourier's proof
If we do the same for every term, we can say that:
Fourier's proof
Notice that R is strictly less than the sum because every term except for the first is overestimated in the formula above.
Since b appears in each denominator, so the smaller b the larger the sum. We know b is a positive integer, so the largest value for the above equation would be if b was 1. In that case, the sum becomes:
Fourier's proof
This is a well-known geometric series that sums to 1. R must be less than this maximum. Since we already know R is greater than 0 we have:
Fourier's proof
There are no integers that are greater than zero but less than one. So R cannot be an integer. As we have already shown, this means that e cannot be rational.

Could it be that absolute mode is faster? For instance, if you are changing the permissions of a whole filesystem (to make it worse, imagine its a network filesystem), having to do a "stat" of the file before changing it makes it slower, right?
Also, i dont see why it is more powerful because u can do the same thing with both. Personally, I prefer absolute mode since my brain can calculate the mask faster than remembering the command flags.

Video Thumbnails: Does Android even recognize them?
Last Updated:

Video Thumbnails:
That's the still frame that displays before you play the video. Sometimes they're known as poster frames.
Does Android even recognize them?
The thumbnail image is a vital thing for a small child to be able to use the tablet device to identify and watch a video.
I'm pretty good with video. I use multiple editing applications, and own sophisticated video compression software like Apple's Compressor and Sorenson Squeeze.
Sorenson Squeeze has a setting to choose the thumbnail image for an MPEG-4 movie. But when that movie is imported into my Nexus 7 tablet, it is disregarded. The Nexus just displays any random frame.
Has anyone figured out how to add your own thumbnail image to a video to be displayed in Android?

I assume you mean like a preview similar to ones you get when watching youtube .... scrolling over a section of video ....
.... I know the note 2 has a thing called airview? not sure if its available on other devices. This lets you hover over a section of video to give you a preview. Also it lets you preview (with sound) a video in the library.

No, not like YouTube.
When you look through the Gallery app on Android, you can see the videos and photos in your collection, with each one represented by a still image.
It's that still image I'm talking about. I want a way to select which still image from the video is displayed when I scroll through the Gallery.
I wondered if there's a way to add artwork to a single video? That might be a way to get it to display a particular image to represent that video. I don't know.
When a 2-year-old child looks through the Gallery, the child needs to see an image that represents the video, to be able to choose which video to watch.
For this reason, not being able to choose that image is a show-stopper. My Nexus 7 is only weeks old, but unfortunately I'm considering switching to Apple's iOS for this reason alone, as it means a child can't use the Nexus tablet.

Stack Overflow is a question and answer site for professional and enthusiast programmers. It's 100% free, no registration required.
I'm struggling with add_custom_command. Let me explain the problem in detail.
I've these set of cxx files and hxx files. I run a perl script on each of them to generate a certain kind of translation file. The command looks like
perl trans.pl source.cxx -o source_cxx_tro
and similarly for header.hxx files as well.
So I'll end up with some multiple commands (each for a file)
Then I run another perl scripn on the output generated from these commands (source_cxx_tro, header_hxx_tro)
perl combine.pl source_cxx_tro header_hxx_tro -o dir.trx
dir.trx is the output file.
I've something like this.
Loop_Over_All_Files()
Add_Custom_Command (OUTPUT ${trofile} COMMAND perl trans.pl ${file} -o ${file_tro})
List (APPEND trofiles ${file_tro})
End_Loop()
Add_Custom_Command (TARGET LibraryTarget POST_BUILD COMMAND perl combine.pl ${trofiles} -o LibraryTarget.trx)
What I expect is when building the post build target, the trofiles will be built first. but it is not the case. The ${trofiles} are not getting built and hence the post build command ends in a failure. Is there any way I can tell the POST_BUILD command depend on the previous custom command ?
Any suggestions ?
Thanks in advance, Surya

Use add_custom_command's to create a file transformation chain
• *.(cxx|hxx) -> *_(cxx|hxx)_tro
• *_(cxx|hxx)_tro -> Foo.trx
and make the last transformation an first class entity in cmake by using add_custom_target. By default this target won't be build, unless you mark it with ALL or let another target that is built depend on it.
set(SOURCES foo.cxx foo.hxx)
add_library(Foo ${SOURCES})
set(trofiles)
foreach(_file ${SOURCES})
string(REPLACE "." "_" file_tro ${_file})
set(file_tro "${file_tro}_tro")
add_custom_command(
OUTPUT ${file_tro}
COMMAND perl ${CMAKE_CURRENT_SOURCE_DIR}/trans.pl ${CMAKE_CURRENT_SOURCE_DIR}/${_file} -o ${file_tro}

You want to create a custom target that consumes the output of the custom commands. Then use ADD_DEPENDENCIES to make sure the commands are run in the right order.
This might be sort of close to what you want: http://www.cmake.org/Wiki/CMake_FAQ#How_do_I_use_CMake_to_build_LaTeX_documents.3F
Basically one add_custom_command for each file generated, collect a list of those files (trofiles), then use add_custom_target with a DEPENDS on the list trofiles. Then use add_dependencies to make the LibraryTarget depend on the custom target. Then the custom target should be built before the library target is built.

USB Device Support on NI Linux Real-Time Operating System
Updated Feb 19, 2020
Reported In
Operating System
• NI Linux Real-Time
Issue Details
I have connected a USB device to my hardware running the NI Linux Real-Time Operating System (RTOS). I have no visual confirmation that the USB device is usable by my hardware. How do I know that it has been recognized or if the USB device is supported?
Solution
The Linux kernel has built-in support for many types of devices including but not limited to USB storage devices and USB webcams. Since the NI Linux RTOS is based on the Linux kernel, support for these devices is included. There is no defined list of hardware that can be referenced for support purposes, but there are ways to determine if a device can be used with the NI Linux RTOS.
Note: The techniques discussed here will require the ability to log in to the NI Linux Real-Time target using a secure shell (SSH) or serial connection to the device. Documentation has been provided in the Related Links section that can assist with this.
Detecting Connected USB Devices:
It is possible to verify that a USB device has been detected by the NI Linux RTOS when it is initially plugged into a USB port on the target. Once logged in to the Real-Time target, connect a USB device and issue the command dmesg to the console, then press enter. Information similar to that shown in Figure 1 will be displayed. You can search the information for text related to the device you have plugged into the target. This is a reliable method for determining if the NI Linux RTOS can identify your device. This does not guarantee that the device is usable with the target.
Figure 1. Typical dmseg Information About a USB Storage Drive
Determining if the Connected USB Device Is Usable by the Target:
The current kernel that the NI Linux RTOS utilizes is the 3.14.40 Linux kernel. When the kernel detects a USB device that it can support, the kernel module (driver) is automatically loaded into memory and the device will become accessible to the user. An easy method to determine if a new kernel module has been loaded for a particular USB device is to issue the lsmod command to the terminal before inserting the device, then issuing the same command after inserting the device. If a module has been loaded, comparing the lists of loaded modules will show the new module.
For most supported USB devices, a module will be automatically loaded for the kernel. There may be times that a module does not load automatically. To manually load a module for the kernel, issue the command modprobe <module> to the terminal. For example, if the ftdi_sio module, a USB-to-Serial driver needs to be loaded, the command would be modprobe ftdi_sio.
USB storage devices will be automatically mounted to the Real-Time target. These can be accessed in the /media location and a shortcut to the drive will generally be mapped as /U unless a folder with that name exists on the system. In such a case, the next available letter is used to map the USB storage device.
Additional Information
List of USB Modules on the NI Linux Real-Time OS:
Many kernel modules are multipurpose and do not make any indication as to what hardware is supported by the module. There are no resources that explicitly list all hardware that is on a specific module. To determine if your hardware is supported by the NI Linux RTOS, a search for the hardware on the internet may allow you to determine the kernel module it is associated with. The current list of USB modules that are included with the NI Linux RTOS can be found in:/lib/modules/<kernel-version>/modules.usbmap.
More Information About a Module:
Most modules that exist for the Linux kernel have documentation that can be referenced online. See the Related Links to learn more about each module. To gain a general idea about the particular function of a module, you can issue the command modinfo <module> to the terminal. This will generally display module developer information as well as a simple description of the function of the module.

ObscureInfo(): Hide Sensitive Information in Access Form Controls
Avoid over-the-shoulder attacks and prevent accidental disclosures in your Microsoft Access forms with this easy-to-implement function.
ObscureInfo(): Hide Sensitive Information in Access Form Controls
To prevent over-the-shoulder attacks–or accidental disclosure during presentations or screenshots–it's good practice to hide the contents of sensitive information in your Access forms.
The ObscureInfo() function does just that. When the control does not have the focus, the function sets the back color to match the fore color (i.e., the text color). When the control gets the focus, the back color is set to white.
The code is easy to apply to multiple controls and is compatible with lightweight forms (i.e., you can call the function directly from the Property Sheet events without needing to use the form code behind module).
The Code
' ----------------------------------------------------------------
' Procedure : ObscureInfo
' Date : 9/21/2009
' Author : Mike Wolfe
' Source : https://nolongerset.com/obscureinfo/
' Purpose : Use to hide data in sensitive fields (e.g., BirthDate, PhoneNum, SSN)
' Usage : Ctl OnEnter property: =ObscureInfo(False, Form.ActiveControl)
' Ctl OnExit property: =ObscureInfo(True, Form.ActiveControl)
' Form Current property: =ObscureInfo(True, [BirthDate], [HomePhone], [SSN])
' Form Load property: =ObscureInfo(True, [BirthDate], [HomePhone], [SSN])
' ----------------------------------------------------------------
Function ObscureInfo(HideIt As Boolean, ParamArray Ctls() As Variant)
Dim Ctl As Variant
For Each Ctl In Ctls
If HideIt Then
If IsNull(Ctl.Value) Then
Ctl.BackColor = vbWhite
Else
Ctl.BackColor = Ctl.ForeColor
End If
Else
Ctl.BackColor = vbWhite
End If
Next Ctl
End Function
Usage: Step-by-Step
The easiest way to apply the changes in form design view is by using the Property Sheet events.
Here's the step-by-step process:
1. Go to Form Design View
2. Select all the controls you want to obscure ([Ctrl]/[Shift] + Click)
3. Set the On Enter property to: =ObscureInfo(False, Form.ActiveControl)
4. Set the On Exit property to: =ObscureInfo(True, Form.ActiveControl)
5. Select the form itself
6. Set the On Current property to: =ObscureInfo(True, [tbBirthDate], [tbSSN])
7. Set the On Load property to: =ObscureInfo(True, [tbBirthDate], [tbSSN])
For step 6, you list the control name (not the field name) of every control you want to be initially obscured when the form opens.
In Action
The controls only get obscured if they contain data. So, for a new record, all the controls have white backgrounds.
When we switch to a populated record, the sensitive information is blacked out:
When we tab into one of the sensitive fields, the background turns white and we can see its contents:
The "Soc Sec Num" text box is active. If you look closely, you can see the cursor before the "123-45-6789" text.
When we tab into the next sensitive field, the previous field blacks out and the new field's contents become visible:
Tabbing from "Soc Sec Num" to "Home Phone" obscures the Soc Sec Num field, selects the text in the Home Phone field, and sets the back color to white so we can see its contents.
Sample Database
There's not much to the code, but if you would like to see it in action, you can download the database I used for the above screenshots:

El Swarm (enjambre) de Docker
dockerswarm
En esta entrada vamos a introducir la funcionalidad Swarm que soporta el motor (engine) de Docker, esto nos permitirá desplegar contenedores en varias máquinas añadiendo una infraestructura clúster entre ellas, y así poder utilizar y compartir los recursos de varias máquinas con Docker como si fuera una única instancia.
La gestión de red y algunos recursos es transparente para el usuario, el Swarm se encarga de orquestar la comunicación entre contenedores, también se publican los puertos compartidos de los contenedores por defecto en todos los nodos, por lo que no tendremos de que preocuparnos, da la posibilidad de escalar servicios fácilmente y distribuirlos entre los nodos, etc.
Iniciar el Swarm
En el Swarm de Docker existen dos tipos de nodos, los manager y los worker, siendo el manager el que delega las tareas a los workers y no al revés, el manager también forma parte del Swarm. En un entorno en producción se recomienda tener mínimo unos tres managers para soportar la tolerancia a fallos.
Se inicia el swarm en el manager con el siguiente comando
$ docker swarm init
Para añadir un manager al Swarm se ejecuta el siguiente comando, hay que seguir las instrucciones en el nodo correspondiente
$ docker swarm join-token manager
Para añadir un worker se ejecuta y seguir las instrucciones
$ docker swarm join-token worker
Una vez añadidos los nodos podremos visualizarlos desde el manager ejecutando
$ docker node ls
Desplegar servicios
Para desplegar (deploy) servicios en el Swarm usaremos docker-compose y la configuración correspondiente que está disponible a partir de la versión 3, configuramos un servicio:
version: '3'
services:
servicio:
image: imagen_del_servicio
deploy:
mode: replicated
replicas: 1
restart_policy:
condition: on-failure
placement:
constraints: [node.hostname==nodehostname]
volumes:
- ssh-entrypoint:/entrypoint:ro
networks:
netservice:
networks:
netservice:
volumes:
ssh-entrypoint:
driver: vieux/sshfs
driver_opts:
sshcmd: user@host:/remote_shared_folder
password: secret
port: 2222
sftp_server: "/usr/bin/sudo /usr/lib/openssh/sftp-server"
allow_other: ""
Ejecutamos el stack que vamos a desplegar en el Swarm
$ docker stack up --with-registry-auth -c docker-compose.yml nombre_del_servicio
La opción –with-registry-auth se utiliza por si usamos imágenes de un registro de Docker propio, el Swarm buscará la imagen a desplegar en los registros que estemos conectados en los nodos y la bajará en cada uno de ellos. Pueden mezclarse arquitecturas para tener un conjunto de imágenes multiarch jugando con el manifest del repositorio, pero esa opción es todavía experimental.
Hemos creado el volumen compartido por sshfs con el driver vieux/sshfs para varias arquitecturas, por lo que cada nodo se conectará a la carpeta /remote_shared_folder del host que indiquemos con la correspondiente configuración por sshfs.
En el apartado node.hostname se indica una máquina concreta para desplegar el servicio, si se omite esta opción se replicará en la que elija el Swarm
Gestión del Swarm
Una vez desplegado el servicio puede verse ejecutando
$ docker service ls
Y si queremos ver uno en concreto
$ docker service ps nombre_del_servicio
Para ver logs de un servicio se ejecuta
$ docker service logs -f nombre_del_servicio
Eliminar un servicio ejecutando
$ docker stack rm nombre_del_servicio
Y eliminar un nodo del Swarm
$ docker node rm nodo_a_eliminar
Por último comentar que podemos usar otras herramientas para gestionar el Swarm como es Portainer, aunque existen otras muchas nos facilita información gráficamente del clúster.

Esto es todo por el momento, volveremos pronto con Kubernetes (k8s), saludos
DNSCrypt y anonimiza tus datos
dnscrypt
Hola, hoy os vamos a comentar en esta entrada como montar vuestro propio cliente DNSCrypt, que nos servirá para anonimizar los datos de resolución de dominio que van por nuestra conexión, esto pondrá un poco más difícil la parametrización que hacen los gobiernos y grandes corporaciones con nuestra información.
¿Qué es DNSCrypt?
DNSCrypt crea un túnel cifrado entre el servidor y el cliente, y resuelve las peticiones DNS que realiza. Evita la suplantación de identidad y utiliza firmas criptográficas para verificar que las respuestas se originan en el sistema y que no hayan sido manipuladas.
Es una especificación abierta, con implementación libre, y que no está afiliada a ninguna empresa u organización.
Usar DNSCrypt
Necesitamos tener instalado el programa dnscrypt-proxy para conectar a un servidor.
$ apt install dnscrypt-proxy
Configuramos el programa para que escuche en el puerto 53 de localhost (127.0.0.1) y se conecte al servidor DNSCrypt de HatThieves.
listen_addresses = ['127.0.0.1:53']
server_names = ['hatthieves', 'hatthieves6']
[static.'hatthieves']
stamp = 'sdns://AQUAAAAAAAAAETgyLjIyMy4zLjEzNTo1NDQzICIJ3we16VXeoGdYSnOd3QYm2h5ZQCUmjS_GNx-JOELOHTIuZG5zY3J5cHQtY2VydC5oYXR0aGlldmVzLmVz'
[static.'hatthieves6']
stamp = 'sdns://AQUAAAAAAAAAHFsyMDAxOmJhMDoxODAwOjgwZTA6OjFdOjU0NDMgIgnfB7XpVd6gZ1hKc53dBibaHllAJSaNL8Y3H4k4Qs4dMi5kbnNjcnlwdC1jZXJ0LmhhdHRoaWV2ZXMuZXM'
Una vez conectado podremos configurar nuestro sistema para que utilice el puerto local.
$ echo 'nameserver 127.0.0.1' > /etc/resolv.conf
Y todas las peticiones del sistema pasarán a través de nuestro servidor que resuelve directamente a los servidores raíz de internet, usamos DNSSEC y no guardamos registros como puede verse en nuestra instancia. También se pueden usar los servidores públicos oficiales.
Un saludo, estad seguros y nos vemos en la próxima entrada.
Libera tu voz con Grumble
grumble
Hola, como ya sabéis, con todo lo que está sucediendo referente a la pandemia está cambiando el estilo de vida. Se tiende a utilizar servicios telemáticos tanto para trabajar, si es posible hacerlo, como en todos los ámbitos: compras, formación, reuniones familiares, etc.
Esta tendencia obliga al usuario a utilizar plataformas “gratuitas” de empresas que se quedan con nuestra voz y datos (ya sabes que cuando algo es gratis el producto eres tú). Por eso queremos hacer hincapié en que los usuarios utilicen servicios gestionados por ellos mismos y alejarse lo máximo posible de dar beneficios a estas empresas que han ganado popularidad con la pandemia y se quedan con los datos (el petróleo del siglo XXI).
Grumble
Si conocéis el famoso programa de chat de voz Mumble, su hermano se llama Grumble. Éste es la implementación en lenguaje Go de Mumble y está en desarrollo. Vamos a instalarlo en una Raspberry Pi ya que no necesita consumir muchos recursos y podremos tenerlo en un servidor casero sin mucho esfuerzo. Utilizaremos Docker para desplegarlo porque es más cómodo, limpio y sus programadores nos han facilitado un Dockerfile en su repositorio.
Creamos una carpeta y clonamos el repositorio:
$ git clone https://github.com/mumble-voip/grumble
En la misma carpeta creamos un archivo docker-compose.yml con el siguiente contenido:
version: '2'
services:
grumble:
build: ./grumble
container_name: grumble
hostname: grumble
restart: always
# volumes:
# - ./data:/data
ports:
- 64738:64738
- 64738:64738/udp
networks:
grumblenet:
networks:
grumblenet:
Con el volumen comentado, construimos la imagen y levantamos el contenedor. Seguidamente copiamos la carpeta /data en la carpeta local para compartir el volumen:
$ docker-compose up -d
Building grumble
Step 1/14 : FROM golang:1.14-alpine as builder
1.14-alpine: Pulling from library/golang
...
$ docker cp grumble:/data .
Y finalmente lo descomentamos todo, lo paramos y volvemos a crear el contenedor:
$ docker-compose down && docker-compose up -d
Ya podemos conectarnos con nuestro cliente favorito a nuestro Grumble como lo haríamos con Mumble, esperamos que os sea de ayuda y os animéis a montarlo para ser dueños de vuestra propia voz cifrada. Nos leemos en la próxima entrada.
TensorFlow 2.0 y redes neuronales
tf_logo
Buenas, hoy vamos a explicar un poco en esta entrada como funciona el framework que nos ofrece herramientas para programar tareas de aprendizaje automático, crear redes neuronales, deeplearning, deep reinforcement learning, etc. En definitiva lo que suelen denominarse hoy inteligencias artificiales, se llama TensorFlow y va por la versión 2.3
TensorFlow es el sistema de aprendizaje automático de segunda generación de Google Brain, liberado como software libre en noviembre de 2015. El nombre TensorFlow deriva de las operaciones que tales redes neuronales realizan sobre arrays multidimensionales de datos. Estos arrays multidimensionales son llamados tensores
Unidad de procesamiento del tensor (TPU)
En mayo de 2016 Google anunció su unidad de procesamiento del tensor (TPU), una construcción ASIC personalizada específicamente para aprendizaje automático y adaptada para TensorFlow. TPU es un acelerador de IA programable diseñado para proporcionar alta eficiencia aritmética de precisión baja, y orientado a utilizar modelos más que para entrenarlos
TensorFlow
La API de TensorFlow está disponible en varios lenguajes, nosotros usaremos la de NodeJS para el ejemplo de red neuronal artificial que construiremos con el conjunto de datos MNIST
// Cargamos los módulos necesarios
const tfnode = require('@tensorflow/tfjs-node-gpu'),
fs = require('fs'),
zlib = require('zlib');
(async () => {
// Leemos el conjunto de datos (dataset) y preparamos los datos para la entrada
const features = (new Uint8Array(zlib.gunzipSync(fs.readFileSync(__dirname + '/mnist/train-images-idx3-ubyte.gz')))).slice(16),
labels = (new Uint8Array(zlib.gunzipSync(fs.readFileSync(__dirname + '/mnist/train-labels-idx1-ubyte.gz')))).slice(8),
featuresTest = (new Uint8Array(zlib.gunzipSync(fs.readFileSync(__dirname + '/mnist/t10k-images-idx3-ubyte.gz')))).slice(16),
labelsTest = (new Uint8Array(zlib.gunzipSync(fs.readFileSync(__dirname + '/mnist/t10k-labels-idx1-ubyte.gz')))).slice(8),
feats = tfnode.data.array((new Float32Array(features)).map(f => f / 255.0)).batch(784),
lbls = tfnode.data.array(labels).batch(1),
featTests = tfnode.data.array((new Float32Array(featuresTest)).map(f => f / 255.0)).batch(784),
lblTests = tfnode.data.array(labelsTest).batch(1)
// Instanciación del modelo
const model = tfnode.sequential()
// Se añaden las capas de la red neuronal
model.add(tfnode.layers.dense({ units: 128, activation: 'relu', inputShape: [784] }))
model.add(tfnode.layers.dropout(0.2))
model.add(tfnode.layers.dense({ units: 10, activation: 'softmax' }))
// Compilación del modelo
model.compile({ optimizer: 'adam', loss: 'sparseCategoricalCrossentropy', metrics: ['acc'] })
model.summary()
console.log(`Training dataset with ${feats.size} features and ${lbls.size} labels...`)
// Fase de entrenamiento del modelo
const dataTrain = tfnode.data.zip({ xs: feats, ys: lbls }).batch(1),
testTrain = tfnode.data.zip({ xs: featTests, ys: lblTests }).batch(1),
history = await model.fitDataset(dataTrain, {
epochs: 5,
validationData: testTrain,
callbacks: {
onTrainBegin: logs => console.log('Start Training...'),
onTrainEnd: logs => console.log('Stop Training'),
onEpochBegin: (epoch, logs) => console.log('Begin epoch: ' + epoch),
onEpochEnd: (epoch, logs) => console.log('End epoch: ' + epoch + '\n- Loss: ' + logs.loss + '\n- Accuracy: ' + logs.acc)
}
}).catch(err => console.error(err))
// Se muestran los valores de salida
Object.keys(history.history).map(key => console.log(`${key}=${history.history[key]}`))
})()
Necesitamos instalar las dependencias del módulo @tensorflow/tfjs-node-gpu para que funcione, o el módulo @tensorflow/tfjs-node en caso de no usar GPU
En el ejemplo anterior estamos leyendo el dataset y creando una red neuronal artificial con 128 neuronas, la capa de dropout permite desactivar un porcentaje de las neuronas durante el entrenamiento en nuestro caso el 20%, esto es necesario para no tener resultados por sobreentrenamiento. Finalmente tenemos 10 unidades en la capa de salida por lo que el resultado será un tensor de 10 elementos que indica la probabilidad de que la imagen sea correcta. Hacemos 5 pasadas de entrenamiento y validamos los resultados
La salida por lo tanto muestra el resumen del modelo y el entrenamiento, dando los valores de pérdida y acierto en cada entrenamiento y al final el total

Una vez entrenado el modelo podremos pasarle imágenes para detectar la coincidencia en la probabilidad de los resultados
// Adaptamos las imágenes a la entrada del modelo y se crea el tensor de entrada
fs.createReadStream('/images.json.gz').pipe(zlib.createGunzip()).on('data', async data => {
const imagen = Float32Array.from(await sharp(Buffer.from(data.image, 'base64')).resize(28, 28).greyscale().raw().toBuffer().catch(err => next(err))),
buffer = tfnode.buffer([1, 784], 'float32', imagen.map(f => f / 255.0))
model.predict(buffer.toTensor()).print()
})
.on('end', () => {
console.log('All images predicted.')

Integración Continua: Gitea + Drone + SonarQube
¿Qué es y para que se usa la integración continua?
Es una práctica de ingeniería de software que consiste en hacer integraciones automáticas de un proyecto lo más a menudo posible para así poder detectar fallos cuanto antes. Entendemos por integración la compilación y ejecución de pruebas de todo un proyecto.
Gitea + Drone + SonarQube
Se utiliza el software libre de Gitea para almacenar los repositorios de código y que conectaremos a Drone para realizar la IC
Drone permite ejecutar las pipelines que tiene configuradas el repositorio, cuenta con mucha variedad de plugins dando posibilidad de despliegues o comunicaciones
SonarQube provee de métricas y analiza la calidad y seguridad del código
Con este stack podremos montar un ciclo de IC que cubre las necesidades básicas, también destaca los pocos recursos que necesita esta configuración pudiendo desplegarse en máquinas pequeñas como una Raspberry
Docker

Solo hay que crear la app en Gitea para conectarla a Drone y generar las claves de la configuración del runner de Drone. También habría que generar la token del plugin de sonar para cada proyecto de Drone que configuremos

Dockerizando una Raspberry Pi 4
En esta entrada vamos a instalar y preparar un ordenador Raspberry Pi 4 con la distribución Buster Debian GNU/Linux y arquitectura arm64 (aarch64) aprovechando al máximo el procesador que lleva de serie
Necesitamos la imagen de RaspiOS oficial con el software arm64 instalado, también necesitaremos una tarjeta microSD para grabarla, esto podemos hacerlo con un solo comando desde un terminal
$ curl -s https://downloads.raspberrypi.org/raspios_arm64/images/raspios_arm64-2020-05-28/2020-05-27-raspios-buster-arm64.zip | gzip -d - | sudo dd if=/dev/stdin of=/dev/sdX status=progress
Donde el dispositivo /dev/sdX será el de la memoria microSD
Una vez termina el comando tendremos la imagen grabada en la tarjeta, la conectamos a la Raspberry Pi 4 y arrancará el sistema por defecto
Abrimos un terminal desde la Raspberry y ejecutamos los siguientes comandos
$ echo 'deb https://download.docker.com/linux/debian buster stable' | sudo tee /etc/apt/sources.list.d/docker.list
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
$ sudo apt update
$ sudo apt install -y docker-ce
Cuando termine de instalar se necesita reiniciar el sistema para que todo funcione correctamente, y ya tenemos docker en nuestro ordenador arm64
$ docker -v
Docker version 19.03.12, build 48a6621
Kernel Version: 5.4.51-v8+
Operating System: Debian GNU/Linux 10 (buster)

Subir vídeos al reproductor IPFS
IPFS logo
Hola, en esta entrada explicaremos como adaptar nuestros vídeos para subirlos a la red IPFS desde nuestra página de Upload y poder visualizarlos con el reproductor IPFS, utilizaremos el software ffmpeg que suele venir disponible en los repositorios de la distribución que estemos usando
Si tenemos por ejemplo un archivo mp4 y queremos adaptarlo al formato HLS con el siguiente comando:
ffmpeg -i video.mp4 -y -acodec aac -vcodec copy -hls_time 60 -hls_list_size 0 -f hls video.m3u8
Y de esta forma trozeamos el archivo mp4 en partes de 60 segundos con formato hls
Una vez termine la transcodificación del archivo vamos a la página de Upload y subimos el directorio generado
Cuando termine de subirse nos devuelve un hash de la carpeta que contiene el vídeo en formato HLS, este hash es el que tenemos que pasarle al reproductor IPFS
Y con esto ya tenemos nuestro vídeo en la red IPFS disponible para verlo desde el reproductor cuando nos apetezca, advertir que se tenga cuidado con los contenidos subidos ya que no pueden borrarse de la red.
Saludos
Docker con IPv6
docker6
Aquí vamos a explicar como habilitar el protocolo IPv6 en Docker, esto permitirá comunicar nuestros contenedores con el mundo exterior por este protocolo aparte del conocido IPv4, funciona solamente en GNU/Linux
Para esto hay que tener configurado en el servidor anfitrión IPv6 en la interfaz WAN (la que llega a internet), en algunos proveedores puede venir activado por defecto pero no es la norma, para probar si tenemos IPv6 en el anfitrión haremos un ping6
$ ping6 2600::
Si responde correctamente las solicitudes ICMPv6 tendremos IPv6 en la máquina, sino hay que negociar con el proveedor como habilitarlo
En el archivo /etc/docker/daemon.json (si no existe lo creamos) hay que añadir lo siguiente como se indica en la documentación de Docker
{
"ipv6": true,
"fixed-cidr-v6": "2001:db8:1::/80"
}
El parámetro fixed-cidr-v6 indica la subred interna que usarán los contenedores, es decir, la subred de la interfaz bridge que normalmente identificamos con docker0, se configurará con la primera dirección de la red disponible
Se elige la máscara de red /80 que es menor que la que hay en la interfaz externa /64 para evitar problemas en el enrutado de los paquetes IPv6, lo recomendable es usar una máscara con un rango menor, si ponemos una máscara /64 o del mismo valor que la externa se tiene que usar algún demonio de enrutado como ndppd
Una vez se reinicia Docker puede verse configurada la interfaz interna de red bridge con IPv6 habilitado y la consiguiente red asignada con el comando
$ docker network inspect bridge
Para usar IPv6 en los contenedores habrá que enrutar el tráfico de vuelta hacia la interfaz externa haciendo masquerading con el comando ip6tables
$ ip6tables -t nat -A POSTROUTING -s 2001:db8:1::/80 -j MASQUERADE
Además hay que configurar el sysctl de la máquina para preparar el kernel con un entorno IPv6, añadimos las siguientes líneas al archivo /etc/sysctl.d/99-sysctl.conf modificando la interfaz de red de salida por la correspondiente (hay que reiniciar la máquina)
net.ipv6.conf.default.accept_ra=0
net.ipv6.conf.all.accept_ra=0
net.ipv6.conf.default.forwarding=1
net.ipv6.conf.all.forwarding=1
net.ipv6.bindv6only=0
net.ipv6.conf.default.disable_ipv6=0
net.ipv6.conf.all.disable_ipv6=0
net.ipv6.conf.default.proxy_ndp=0
net.ipv6.conf.all.proxy_ndp=0
net.ipv6.conf.ensXXX.proxy_ndp=1
net.ipv6.conf.ensXXX.accept_ra=2
net.ipv6.conf.ensXXX.forwarding=0
Solo queda instanciar un contenedor y comprobar que tenemos ping6 desde él
$ docker run -ti --rm debian:buster ping6 -c10 2600::
PING 2600::(2600::) 56 data bytes
64 bytes from 2600::: icmp_seq=1 ttl=52 time=140 ms

Usa Virt-Manager NO VirtualBox
logo-virt-manager
Desde que se lanzó la versión 10 de Debian GNU/Linux (Buster) en su página nos recomiendan dejar de usar VirtualBox por la aplicación de escritorio Virt-Manager
apt install virt-manager
Ya conocemos desde hace años VirtualBox de Oracle para trabajar con máquinas virtuales, es OpenSource aunque el producto está controlado por la misma empresa. Como alternativa ahora se utiliza Virt-Manager que está basado en KVM y libvirt, aunque también puede gestionar Xen o LXC directamente
Como podéis ver el entorno nos recuerda mucho a otras aplicaciones de virtualización como VMware o VirtualBox, al crear una máquina virtual nos da a elegir el tipo de instalación que queremos realizar
Una vez configurados los parámetros del menú wizard, se generan los recursos necesarios para arrancar la máquina virtual, esto podemos realizarlo también mediante comandos pero la GUI nos facilita mucho la tarea
También hay que configurar las interfaces de red que se asignarán a las máquinas virtuales, aunque la aplicación lo hace todo a golpe de ratón con permisos de root
Como se puede ver el menú nos recuerda mucho a otras aplicaciones de virtualización, aunque difieren muchas de las configuraciones, por ejemplo no hay límites a la hora de asignar los núcleos del procesador a una máquina virtual, pero la aplicación nos avisa que puede incurrir en un bajo rendimiento
Os animo a probarlo y utilizarlo como alternativa a otras aplicaciones de virtualización tanto comerciales como libres y comprobar la potencia que nos ofrece la virtualización del Kernel de GNU/Linux, como ya recomendó hace años fanta en su blog, saludos

DWRequest: MooTools 1.2 AJAX Listener & Message Display
By on
Though MooTools 1.2 is in its second beta stage, its basic syntax and theory changes have been hashed out. The JavaScript library continues to improve and become more flexible.
Fellow DZone Zone Leader Boyan Kostadinov wrote a very useful article detailing how you can add a Gmail-like AJAX display to your website using the Prototype JavaScript library. The article got me to thinking: could it be helpful to always display an AJAX notification message upon every request's initial request, success event, and failure event? Maybe even only for debugging purposes?
Whatever your reason may be, I've created the DWRequest MooTools class to inform the user or developer of each AJAX request and subsequent result.
The CSS Code
#message { display:none; width:150px; text-align:center; padding:5px 8px; font-weight:bold; position:absolute; right:2%; font:12px arial; }
The XHTML Code
The following code is an example of two XHTML links that make AJAX calls. Note the message DIV.
<body>
<div id="message">Performing Request...</div>
<a href="inputs.php" class="ajax">Succeed</a><br />
<a href="sug.php" class="ajax">Fail</a>
</body>
The MooTools JavaScript Code
var DWRequest = new Class({
Extends: Request,
options: {
onRequest: function() {
show_ajax_message('request');
},
onSuccess: function() {
show_ajax_message('success');
},
onFailure: function() {
show_ajax_message('failure');
},
onCancel: function() {
show_ajax_message('cancel');
}
}
});
//adds initial events
window.addEvent('domready',function() {
//for every action class
$$('.ajax').each(function(el) {
//add an event..
el.addEvent('click', function(e) {
e = new Event(e).stop();
//make ajax request
var req = new DWRequest({
url: el.get('href'),
method: 'get',
data: 'something'
}).send();
});
});
});
//shows the block
function show_ajax_message(state)
{
//set position
$('message').setStyle('top',window.getScrollTop() + 10);
//on request...
if(state == 'request')
{
//show the box
$('message').addClass('onrequest').setText('Performing Request...').setStyles({'background-color':'#fffea1','display':'block','opacity':'100'});
}
//on success
else if(state == 'success')
{
//take care of box
$('message').set('text','Request Complete!');
//do effect
var myMorph = new Fx.Morph('message',{'duration':1000});
myMorph.start({'opacity': 0,'background-color': '#90ee90'});
}
else if(state == 'failure')
{
//take care of box
$('message').set('text','Request Failed!');
//do effect
var myMorph = new Fx.Morph('message',{'duration':1000});
myMorph.start({'opacity': 0,'background-color': '#ff0000'});
}
else if(state == 'cancel')
{
//take care of box
$('message').set('text','Request Cancelled!');
//do effect
var myMorph = new Fx.Morph('message',{'duration':1000});
myMorph.start({'opacity': 0,'background-color': '#fffea1'});
}
}
The Explanation
1. Once the DOM is ready, any link with the class ajax is listened to -- upon click, a DWRequest class instance is created.
2. I've extended the MooTools Request class, adding default actions for the onRequest, onFailure, onCancel, and onComplete events. (Calls the show_ajax_message() function.)
3. The function displays and manipulates the message DIV as needed: color morphing, message changes, and positioning.
Do you have any suggestions for my class? Please share!

1. Great little script!
The only thing I’d add is more information about the faillure message. Like wich type is it. Because that’s meaningfull if it’s used for debugging.
Also it can be “extended” by shooting the php error message in the postback nad showing it in the message box, like… this value is missing or inexistant, etc. depending on which type of request you’ve fired, but that’s getting a bit out of the js part ;).
gj!
2. Thank you for your ideas Keven!
In terms of versioning, I guess I’d consider this a “0.1”. I hope to continue working on this class, adding user-friendly icons and providing more information about the Ajax request itself (displaying url, execution time, …)
3. Use switch statement instead of the if, it is more appropriate here and the performance is better.
Why you have called it *DW*Request? what is the meaning?
4. Right nir, I’ll incorporate a switch next time. The “DW” is simply my attempt at tracking usage (my initials).
5. Wouldn’t it be more mootoolesk to add the function show_ajax_message to the class, cause there is no other one that will use it.
6. @Andreas: Absolutely. After I published the article, I kicked myself for not doing that. I’ll do that in the next version.
@All: Any more suggestions?
7. Fabrice Terrasson
Tried to extend Request.HTML without success. Any clue ?
8. acctman
do you have any examples or tips for using this to display a notification to a user? Pretty much what I want to do is if the user is on the site, and i need to send out a notification to all users, how would i call the Request… ? is there anyway to do this, what method would work without having the user to reload a page to see the message. I.e. in a chat room
9. Cheers David,
http://paste.davidwalsh.name/78
I’m using your code in my Ajax-based-Joomla.
Actually, it’s highly modified as I’ve made a simple generic class.
Hope you don’t mind to take look in your pastebin area.
Thank You. Thank You. Thank You.
note: pastebin looks great… I’ve never known you have it.
Wrap your code in <pre class="{language}"></pre> tags, link to a GitHub gist, JSFiddle fiddle, or CodePen pen to embed!

I am learning Vanilla JS and DOM. Today I have a problem when I want to remove a class of all elements expect one.
const panels = document.querySelectorAll(".panel");
function toggleOpen() {
this.classList.toggle("open");
console.log(panels);
}
function toggleActive(e) {
if (e.propertyName.includes("flex")) {
this.classList.toggle("open-active");
}
}
panels.forEach((panel) => panel.addEventListener("click", toggleOpen));
panels.forEach((panel) =>
panel.addEventListener("transitionend", toggleActive)
);
I want when I click "panel" the only panel be clicked have class "open" and remove all class "open" of all another "panel". (Exactly I want only a panel to have class "open" in all time, and it can toggle.) Thank you for your help.

In toggleOpen, iterate over all panels (except this one) and remove their open class first:
function toggleOpen() {
// Close all other panels:
for (const panel of panels) {
if (panel !== this) {
panel.classList.remove('open');
}
}
// Either open this panel or close it:
this.classList.toggle("open");
}

• Thanks you so much. Now i know "this" can be use like that.

How to check CPU temperature ? Top methods to reduce overheating
Overheating
Heat is a computer’s enemy. To prevent overheating, computers are specifically designed with heat dispersion and ventilation. When too much heat builds up, there's a chance that the computer may become unstable, resulting in unexpected shutdown or some component damage.
There are several ways to check the CPU's temperature. Users, who prefer the hard way, can open the BIOS settings where third-party tools can be used to check the temperature of the CPU. However, there are various CPU temp monitor tools for Windows 10. These tools may work with older versions such as Windows 7 and Windows 8.1. Here is the list of top 5 free tools for checking CPU temperature.
1. Open Hardware Monitor
The first one on the list will be the Open Hardware Monitor tool. As the name says, the tool is open source and can be downloaded for free. The UI is clean and easy to use, also CPU temperature can be checked along with the GPU. It also displays various details like RAM consumption, CPU operating speed, and the power supply stats.
2. Speccy
Speccy is a famous tool developed by Piriform CCleaner. The tool provides a lot of information, in addition, it's arranged in a way that makes it easy to understand. The only disadvantage is the lack of information related to internal-GPU.
3. HWMonitor
CPU-ID developed this software that is very popular to check CPU temperature. It offers more details regarding the hardware and can also show temperature readings for the integrated GPU in addition to the CPU.
4. SpeedFan
Another CPU temp monitor tool that one can try on your Windows 10 (or older) machine is SpeedFan. The main purpose of SpeedFan is to let users manually control the speed of the cooling fan on your machine. Moreover, there are numerous other functions that analyze the temperature of the PC.
5. Core Temp
Core Temp is the last one on the list that can be used to check CPU temp. One major thing is that users can view the temperature levels in the notification area in the Taskbar. One of its selling points is that you can add a bunch of add-ons to improve its functionality. For example, Core Temp Gadget can we added, which is a widget displayed on the screen.
How to fix CPU Overheating?
Overheating is a major issue nowadays and can cause many problems that can damage the PC. Here is the list of measures you can make to reduce overheating.
1. Maintain good airflow around your PC
The most basic and essential method is to maintain airflow to keep the machine cool. Remove any obstacles that are obstructing the airflow and also check if the fan inside the CPU is working properly or not.
2. Choosing the right case
The case plays a crucial role in maintaining proper airflow dynamics and ensure heat is dissipating efficiently.
3. Using PC at low-power settings
Using a PC at high-power has many benefits. However, the computer doesn't need that much power at all times and many people forget to switch back to low-power after using it. Sometimes. it may be the cause for overheating and one should keep that in mind.
4. Check for the external culprits
Another reason why the PC overheat is because of some apps running on it. If the temperature levels on your machine are significantly higher when you’re doing nothing, then the culprit could be some other apps that are exhausting all the system resources. So, it is advised to find and shut them down using the Task Manager.
5. Cleaning the blocked heat sink and remove internal dust
Dust may get deposited inside the machine and may overheat it and affect the performance. Cleaning the machine on regular basis can prevent overheating. Also, one might consider cleaning the heat sink and other components of the machine.

hack facebook without survey
Title: The Truth About Hacking facebook -parental-controls-guide”>Facebook Without Surveys
Introduction:
In today’s digital age, social media has become an integral part of our lives, with Facebook being one of the leading platforms. However, the desire to hack into someone’s Facebook account without surveys has become a popular topic of discussion. In this article, we will explore the truth behind hacking Facebook accounts without surveys, the legality of such actions, and the potential risks involved.
Paragraph 1: Understanding Facebook Security Systems
Facebook is committed to protecting its users’ privacy and security. The company has implemented robust security measures to safeguard user accounts, including two-factor authentication, encryption, and regular security updates. These measures make it increasingly difficult for hackers to gain unauthorized access to Facebook accounts.
Paragraph 2: The Legality of Hacking Facebook Accounts
Hacking Facebook accounts without the owner’s consent is illegal and unethical. It violates the computer Fraud and Abuse Act (CFAA) in the United States and similar laws in other countries. Engaging in such activities can lead to severe legal consequences, including fines and imprisonment.
Paragraph 3: The Rise of Social Engineering Attacks
Social engineering is a technique that exploits human psychology to manipulate individuals into revealing sensitive information. Hackers often resort to social engineering tactics to gain unauthorized access to Facebook accounts. These attacks involve tricking users into sharing their login credentials or other personal information voluntarily.
Paragraph 4: Common Techniques Used in Facebook Hacking
Despite the security measures in place, hackers continually develop new techniques to exploit vulnerabilities in Facebook’s system. Some common hacking methods include phishing, keylogging, brute force attacks, and malware distribution. However, it’s important to note that these techniques still require the victim’s active participation, such as clicking on malicious links or downloading infected files.
Paragraph 5: The Risks of Hacking Facebook Accounts
Attempting to hack a Facebook account without proper authorization poses significant risks. Firstly, you risk legal consequences, as mentioned earlier. Secondly, hacking is a violation of user privacy, and your actions can have severe emotional and psychological impacts on the victim. Lastly, hackers themselves are vulnerable to being hacked, as they often interact with malicious individuals in underground online communities.
Paragraph 6: The Myth of Survey-Based Facebook Hacking Tools
Numerous websites and tools claim to provide a way to hack Facebook accounts without surveys. However, these claims are often deceptive and misleading. Most of these websites are scams that aim to collect personal information or distribute malware to unsuspecting users. It is essential to exercise caution and avoid falling into these traps.
Paragraph 7: Ethical Hacking and Security Awareness
Ethical hacking, also known as white-hat hacking, is a legitimate practice aimed at identifying and fixing vulnerabilities in computer systems. Ethical hackers work with the consent of the system owner and follow strict guidelines to ensure no harm is done. Instead of attempting to hack Facebook accounts without surveys, individuals interested in cybersecurity should consider pursuing ethical hacking certifications and contribute positively to the field.
Paragraph 8: Protecting Your Facebook Account
While it may not be possible to completely eliminate the risk of being hacked, there are steps you can take to enhance your Facebook account’s security. Enable two-factor authentication, use strong and unique passwords, be cautious of suspicious links and attachments, and regularly update your device’s software and antivirus programs. Additionally, educate yourself about common hacking techniques to identify and avoid potential threats.
Paragraph 9: Reporting Suspicious Activity
If you suspect that your Facebook account has been compromised or notice any suspicious activity, report it immediately to Facebook’s support team. They have dedicated resources to help investigate and resolve security-related issues. By promptly reporting incidents, you not only protect your own account but also contribute to the overall security of the Facebook community.
Paragraph 10: Conclusion
Hacking Facebook accounts without surveys is not only illegal but also unethical. Facebook’s robust security measures make it increasingly difficult for hackers to gain unauthorized access. Instead of engaging in illegal activities, individuals should focus on ethical hacking practices, enhancing their own cybersecurity, and promoting online safety awareness. Remember, protecting privacy and security should always be a priority in today’s digital world.

SQL Question
How to return second newest record in SQL?
If this:
SELECT *
FROM Table
WHERE Date=( SELECT MAX(Date)
FROM Table
)
returns newest record from the table, how to get second newest record?
Answer
SELECT *
FROM Table
WHERE Date = ( SELECT MAX(Date)
FROM Table
WHERE Date < ( SELECT MAX(Date)
FROM Table
)
) ;
or:
SELECT TOP (1) *
FROM Table
WHERE Date < ( SELECT MAX(Date)
FROM Table
)
ORDER BY Date DESC ;
or:
SELECT *
FROM
( SELECT t.*
, ROW_NUMBER() OVER(ORDER BY Date DESC) AS RowNumber
FROM Table t
) AS tmp
WHERE RowNumber = 2 ;
If the Date column has unique values, all three queries will give the same result. If the column can have duplicate dates, then they may give different results (when there are ties in 1st or 2nd place). The first query will even give multiple rows in the result if there are ties in 2nd place.

Cover image for JavaScript Prototypes and Class Inheritance
JavaScript Prototypes and Class Inheritance
akdeberg profile image Anik Khan ・3 min read
Javascript is object-based. Understanding the object system is very crucial to write a better, flexible, and robust application.
Not Your Typical Object System
It's important to note that javascript's object system is different from other major languages.
Javascript's object system is prototype based.
Major languages like Python, C#, Java are class based
So it's important to keep in mind that javascript's object system has a different mechanism than other commonly used ones.
Create a protypical object
Let's create an object using prototypes-
//here Vehicle is a constructor function to create Vehicle Object
let Vehicle = function (hasEngine) {
this.hasEngine = hasEngine
}
//every js object has prototype. let's add a method to it
Vehicle.prototype.getDetails = function () {
return `Vehicle Details------ Any Engine: ${this.hasEngine}`
}
Now getDetails() method is a part of Vehicle object via the prototype.
This code below will create a new object with Vehicle constructor and assign the values.
//the new keyword creates an object with Vehicle constructor
let vehicleOne = new Vehicle(true)
//remember we added the getDetails method to Vehicle using prototype;
//here we invoke it
console.log(vehicleOne.getDetails())
//OUTPUT
Vehicle Details------ Any Engine: true
Prototypical Inheritance
Now let's take it one step further. Besides creating object using prototype we can use it for inheritance. This way of doing is known as prototypical inheritance.
Let's create a Car object that inherits from Vehicle-
let Car = function (hasEngine, model, color) {
//hasEngine will belongs to Vehicle so we call it
//and attach it to this Car object
Vehicle.call(this, hasEngine)
this.model = model
this.color = color
}
//Car will use Vehicle's prototype; thus will get the getDetails method
Object.setPrototypeOf(Car, Vehicle.prototype)
Car.prototype.getCarInfo = function () {
return `Car Details------ Model: ${this.model}, Color: ${this.color}, Any Engine: ${this.hasEngine}`
}
//calling the Vehicle actually calls the constructor
let carOne = new Car(true, 'Model X', 'Black')
console.log(carOne.getCarInfo())
//OUTPUT
Car Details------ Model: Model X, Color: Black, Any Engine: true
What this code does is essentially give the Car object to access to Vehicle prototypes. This will allow Car object to having the methods and properties of Vehicle object.
Alt Text
Be Aware
Using ES6+ class syntax the code can be written as follows-
class Vehicle {
constructor(hasEngine) {
this.hasEngine = hasEngine
}
//method
getDetails() {
return `Vehicle Details------ Any Engine: ${this.hasEngine}`
}
}
//calling the Vehicle actually calls the constructor
let vehicleOne = new Vehicle(true)
console.log(vehicleOne.getDetails())
//inherit
class Car extends Vehicle {
constructor(model, color) {
super(true)
this.model = model
this.color = color
}
carDetails() {
return `Car Details------ Model: ${this.model}, Color: ${this.color}, Any Engine: ${this.hasEngine}`
}
}
//calling the Vehicle actually calls the constructor
let carOne = new Car('Model X', 'Black')
console.log(carOne.carDetails())
The output is the same. So one might think this is the exact same thing as a prototypical inheritance; which is pretty wrong.
Using class syntax is like mimicking Java or C#'s class-based inheritance using js prototypical inheritance.
Class-based inheritance is always dangerous; it's wise to use composition. Yet in js using the class syntax we are mimicking the dangerous class inheritance. It's something that should be avoided at any cost.
Quote from Eric Elliot
Using class inheritance in JavaScript is more like driving your new Tesla Model S to the dealer and trading it in for a rusted out 1973 Ford Pinto.

[Bug] Regex was wrong. [Improved] file_get_contents - restricted to the first 12 bytes. Should improve performance. <?php function strhex($string) { $hex = ""; $len = strlen($string); for($i = 0; $i < $len; ++$i) { $hex .= str_pad(dechex(ord($string[$i])), 2, 0, STR_PAD_LEFT); } return $hex; } $data = file_get_contents($filename, FALSE, NULL, -1, 12); if(preg_match('/\.(jpg|jpeg|gif|png)/i', $filename, $matches)) { $type = ($matches[1] === 'jpeg') ? 'jpg' : $matches[1]; } else { // Get the first 12 bytes of the file // Could probably do strhex($data) - but this might be safer..? $hdr = strhex($data[0].$data[1].$data[2].$data[3].$data[4].$data[5].$data[6].$data[7].$data[8].$data[9].$data[10].$data[11]); echo $hdr; // Match header of the file (Google it). if(preg_match('/^ffd8ffe0....4A46494600/i', $hdr)) { // JPEG? $type = 'jpg'; } elseif(preg_match('/^89504e470D0a1a0a/i', $hdr)) { // PNG? $type = 'png'; } elseif(preg_match('/^474946/i', $hdr)) { // GIF? $type = 'gif'; } else { // Unknown image type. } }

Only works if the file has the correct extension.. This determines type by looking at the first 12 bytes of the file (the file's header).
Snippets Manager replied on Tue, 2009/07/21 - 5:08pm
PHP has got a function for that already, its called pathinfo(). It returns an array of information about a file path, so say if you just wanted to test if the file was a specific type then you could just do this: $ext = pathinfo('path/to/file', PATHINFO_EXTENSION); // When you set an option, the function returns a string if ($ext === 'jpg') { // Do something if the file is a jpg } else if ($ext === 'png') { // Do something if the file is a png } else if ($ext === 'gif') { // Do something if the file a a gif } else { return false; }

Some [[TiddlyWiki macros|Core Macros]] define [[access keys|http://en.wikipedia.org/wiki/Access_key]], whose invocation is browser-specific:
| !Action | !PC | !Mac |h
|[[search|Search]]|SHIFT+ALT+F| CTRL+F|
|[[save changes|saveChanges]]|SHIFT+ALT+S| CTRL+S|
|[[new tiddler|newTiddler]]|SHIFT+ALT+N| CTRL+N|
|[[new journal|newJournal]]|SHIFT+ALT+J| CTRL+J|
For Firefox versions prior to 2.0 the default modifier is ALT only rather than SHIFT+ALT.
As of Opera 7.0 on the PC and Mac, press and release SHIFT+ESC and then press the shortcut letter without any modifier.
!Description
The closeAll macro outputs a button to close all open tiddlers.
!Usage

[[Bookmarklets]] are small chunks of JavaScript that you can save as a bookmark in your browser. When opened in the context of a TiddlyWiki, they act as a plugin that is saved in the browser, independent of the TiddlyWiki documents itself.
See [[Bookmarklets]]...
Besides [[primitive types|Primitive Types]], objects provide the basic element in JavaScript for you to get creative -- you can equip it with [[Properties]] and [[Functions]] or turn it into a [[Class|Classes]] to create new instanciate from.

While {{{<<someMacros>>}}} work just like that, a TiddlyWiki macro may allow you to specify either simple parameters or named parameters.
!!!"""Simple Parameter Definition"""
Some macros only require a single parameter, e.g.:
{{{<<someMacro parameterValue>>}}}
For others, the macro author may have defined a fixed parameter sequence, e.g.:
{{{<<someMacro param1Value param2Value param2Value>>}}}
!!!"""Named Parameter Definition"""
Named parameters allow you to specify the values for predefined variables that are recognized by the macro by their name so that their sequence is of no importance, e.g.:
{{{<<someMacro namedParameter:yourValue>>}}}
In rare occasions, as with the [[newTiddler]] macro, a named parameter may be overloaded, e.g.:
{{{<<newTiddler tag:tag1 tag:"tag 2">>}}}
This will actually allow you to create a <<newTiddler label:"new tiddler" prompt:"Create a new tiddler with tags 'tag1' and '[[tag 2]]'..." tag:tag1 tag:"tag 2">> with both {{{tag1}}} and {{{tag 2}}} as its tags; i.e. the macro can handle multiple values passed down to it for the same named parameter {{{tag}}}.
!!!"""How TiddlyWiki Parses Parameters"""
For a visual reference as to how TiddlyWiki parses macro parameters, see [[ParamParser|http://paramparser.tiddlyspace.com/#ParamParserMacro]].
!!!"""Value Delimiters"""
For both, simple parameters or named parameters, you can use any of the following options to delimit parameter values:
;no quotes
:{{{<<someMacro param1 param2>>}}}
;single quotes
:{{{<<someMacro 'param1' 'param 2'>>}}}
:usually used for values containing spaces
;double quotes
:{{{<<someMacro "param1" "param 2">>}}}
:may be handy when you need to nest quotes
;double square brackets
:{{{<<someMacro [[Tiddler A]] [[Tiddler B]]>>}}}
:the most safe and visual way to reference tiddlers, but not necessarily
;double curly brackets
:{{{<<someMacro param:{{<code>}}>>}}}
:{{alert{Caution!}}} The {{{<code>}}} is actually [[evaluated as javascript|Evaluated Parameters]] and the result used as the parameter value.
!!!"""Empty Values"""
To pass down an empty value, i.e. to override an otherwise non-empty default value, you can pass down either of the following as the parameter value:
;empty single quotes
:{{{''}}}
;empty double quotes
:{{{""}}}
;empty double square brackets
:{{{[[]]}}}

A TiddlyWiki is built on the following classes implemented in JavaScript...
;[[Tiddler.class]]
:» the atomic base elements in the TiddlyVerse -- tiddlers
;[[TiddlyWiki.class]]
:» the framework that brings [[tiddlers|Tiddler]] to life
;[[Story.class]]
:» manages the display area where TiddlyWiki renders tiddlers
;[[Wikifier.class]]
:» manages conversion of representations, e.g. [[TiddlyWiki Markup]]@tiddlywiki to [[HTML]]

The resumeNotifications method of a [[TiddlyWiki class|TiddlyWiki]] object resumes issuing notifications after [[suspendNotifications|TiddlyWiki.prototype.suspendNotifications]] is called. If [[suspendNotifications|TiddlyWiki.prototype.suspendNotifications]] was called multiple times, this method must be called an equal number of times in order for notifications to occur. This method does not expect any parameters.

!About YourSearch
YourSearch gives you a bunch of new features to simplify and speed up your daily searches in TiddlyWiki. It seamlessly integrates into the standard TiddlyWiki search: just start typing into the 'search' field and explore!
!Description
The [[tagging]] macro lists all the tiddlers for a specified tag.
!Usage
{{{
<<tagging [[TagName]]>>
}}}
!Parameters
Pass the name of the tag for which you want the tagging list as the first parameter to the macro.
Optionally you can use a second, named parameter called {{{sep}}} to define a minimalistic separator displayed between each list item.
!Example
{{{
<<tagging [[Core Macros]]>>
}}}
<<tagging [[Core Macros]]>>
!CSS Separator
Instead of using the {{{sep}}} parameter, you are better advised to wrap the {{{<<tagging>>}}} macro in a custom class along with desired css rules for it in your StyleSheet, e.g.:
{{{
.viewer .listWrapper li {
margin-top:1px;
background:[[ColorPalette::TertiaryPale]];
list-style-type:none;
padding:0;
}
.viewer .listWrapper li .tiddlyLink {
display:block;
padding:0 4px;
}
.viewer .listWrapper li.listTitle {
background:transparent;
}
}}}
Then use the custom class, here {{{.listWrapper}}}, around your macro like this...
{{{
{{listWrapper{<<tagging [[Core Macros]]>>}}}
}}}
{{listWrapper{
<<tagging [[Core Macros]]>>
}}}
The layout of a TiddlyWiki is defined in shadow tiddlers which serve as templates that contain HTML...
;[[PageTemplate|PageTemplate...]]
:» the overall page layout
;[[ViewTemplate|ViewTemplate...]]
:» the layout for an individual tiddler when viewing it |
;[[EditTemplate|EditTemplate...]]
:» the layout for a tiddler when editing it
''Note'': The commands in a tiddler toolbar are defined in a shadow tiddler called [[ToolbarCommands]].
![[Visual Layout|Layout]]
<<tiddler "Layout">>
![[TiddlySpace Layout]]
<<tiddler "TiddlySpace Layout">>
!Summary
This <<tag global>> function creates a DOM text node.
!Signature
{{{TiddlyWiki.prototype.createTiddlyText = function(parent, text) {} }}}
!Returns
DOM reference: to the created text node
!Arguments
;1. (DOM reference) parent
:the DOM element where the text node will be placed
;2. (string) text
:the text content to be added to ''parent''
!Example
{{{
createTiddlyText(foo,'bar');
}}}
''outputs:'' "bar" in ''foo''
!Summary
The TiddlyWiki core code is stored and developed as a collection of individual files, which makes it more manageable. A recipe file determines which code files, tiddlers and HTML components to put together - somewhat like a jigsaw puzzle.
!Cook
[[Cook]] then reads the recipe file and generates a new TiddlyWiki document from it.
Recipes can reference one another, making it straightforward to create a multiple variants of TiddlyWiki at one time.
!Example
The default [[default recipe file|http://svn.tiddlywiki.org/Trunk/core/tiddlywiki.html.recipe]] for TiddlyWiki:
{{{
template: html/tiddlywiki.template.html
recipe: tiddlers/split.recipe

FAQ about using the [[HideWhenPlugin from MPTW|http://mptw.tiddlyspot.com/#HideWhenPlugin]].
!!Using ~HideWhen to do conditional toolbars based on user name
Replace the normal toolbar comand in the ViewTemplate tiddler with the following:
{{{
<div class='toolbar'
macro="showWhen config.options.txtUserName == '~MyName' ">
<span macro='toolbar editTiddler closeOthers closeTiddler'></span>
</div>
<div class='toolbar'
macro="showWhen config.options.txtUserName !='~MyName' ">
<span macro='toolbar closeOthers closeTiddler'></span>
</div>
}}}
!!Using ~HideWhen to do conditional fields based on tags
Let suppose you have a some tiddlers tagged with "friend" and you'd like to use some custom field to maintain some information about them, say their favourite food.
In the ViewTemplate:
{{{
<div macro="showWhen tiddler.tags.contains('friend')">
Favourite food: <span macro="view favouritefood"></span>
</div>
}}}
In the EditTemplate:
{{{
<div macro="showWhen tiddler.tags.contains('friend')">
Favourite food: <span macro="edit favouritefood"></span>
</div>
}}}
Now you can view and edit your friends' favourite food.
If you wish to have the same field show for your business contacts as well as your friends then you would do it like this:
In the EditTemplate:
{{{
<div macro="showWhen tiddler.tags.containsAny(['friend','contact'])">
Favourite food: <span macro="edit favouritefood"></span>
</div>
}}}
In the ViewTemplate:
{{{
<div macro="showWhen tiddler.tags.containsAny(['friend','contact'])">
Favourite food: <span macro="view favouritefood"></span>
</div>
}}}
Note that custom fields must be lower case. See http://trac.tiddlywiki.org/ticket/356 for details.
!!Making editable custom fields appear on a new tiddler
Create a customized newTiddler button:
{{{
<<newTiddler
label:'Add Training'
tag:'Training'
title:'New Training'
>>
}}}
Place the following in the EditTemplate:
{{{
<div macro="showWhen
tiddler.tags.contains('Training') ||
tiddler.title == 'New Training'">
[[TrainingTemplateEdit]]
</div>
}}}
Create a TrainingTemplateEdit tiddler to put all of your desired custom fields in.
Placing each collection of custom fields in a separate tiddler helps cut down on the confusion of having multiple different things going on in your ViewTemplate & EditTemplate, as well as making it easier to safe guard against accidentally deleting or over writing one of them and losing everything.

!Summary
TiddlyWiki provides flexible means to output tables.
!!"""Simple Tables"""
{{{
|North West|North|North East|
|West|Here|East|
|South West|South|South East|
}}}
|North West|North|North East|
|West|Here|East|
|South West|South|South East|
!!"""Cell Formatting"""
*Insert a space before cell content to right justify cell
*Insert a space after cell content to left justify cell
*Insert spaces before and after cell content to centre justify cell
*Insert an exclamation mark ({{{!}}}) as the first non-space character of a cell to turn it into a header cell
{{{
|!First column|!Second column|!Third column|
|left | centre | right|
}}}
|!First column|!Second column|!Third column|
|left | centre | right|
!!"""Table Headers and Footers"""
* Mark a table row as a header by adding an 'h' to the end
* Mark a table row as a footer by adding an 'f' to the end
{{{
|NW|N|NE|h
|W|X|E|
|SW|S|SE|f
}}}
|NW|N|NE|h
|W|X|E|
|SW|S|SE|f
Use an exclamation mark to turn an individual cell into a header cell of type {{{<th}}}...
{{{
| NW| !N |NE |h
| !W| X |!E |
| SW| !S |SE |f
}}}
| NW| !N |NE |h
| !W| X |!E |
| SW| !S |SE |f
!!"""Table Caption"""
A caption can be added to a table by adding a {{{c}}} after the last column either before the main table...
{{{
|A caption above the table|c
|North West|North|North East|
|West|Here|East|
|South West|South|South East|
}}}
|A caption above the table|c
|North West|North|North East|h
|West|Here|East|
|South West|South|South East|
or after the main table...
{{{
|North West|North|North East|
|West|Here|East|
|South West|South|South East|
|A caption below the table|c
}}}
|North West|North|North East|h
|West|Here|East|
|South West|South|South East|
|A caption below the table|c
!!"""Merging Table Cells"""
Merge a cell horizontally with the one to its right using greater-than {{{>}}}...
{{{
|North West|North|North East|
|>|>|West and Here and East|
|South West|South|South East|
}}}
|North West|North|North East|
|>|>|West and Here and East|
|South West|South|South East|
Merge a cell vertically with the one above using a tilde {{{~}}}...
{{{
|Westerly|North|North East|
|~|Here|East|
|~|South|South East|
}}}
|Westerly|North|North East|
|~|Here|East|
|~|South|South East|
!!"""CSS Formatting for Tables"""
A CSS class can be added to an entire table using a special first row that ends with a {{{k}}}...
{{{
|myClass|k
|North West|North|North East|
|West|Here|East|
|South West|South|South East|
}}}
Use your StyleSheet tiddler to define the desired styles.
CSS properties can also be added to individual table cells by appending the CSS syntax directly after the delimiting pipe {{{|}}}.
{{{
|color:red; North West|opacity:0.5;North|North East|
|color(green):West|Here|East|
|South West|South|South East|
}}}
|color:red; North West|opacity:0.5;North|North East|
|color(green):West|Here|East|
|South West|South|South East|
!!"""Alternating Row Colors"""
TiddlyWiki automatically assigns the classes {{{oddRow}}} and {{{evenRow}}} to table row elements {{{<TR>}}}. These can then be styled using the StyleSheet tiddler:
{{{
.viewer tr.oddRow { background-color: #fff; }
.viewer tr.evenRow { background-color: #ffe; }
}}}
A reference of all [[TiddlyWiki Core|Dev.Core]] functions...
{{functions{<<list filter [tag[Function]][tag[function]][sort[title]]>>}}}<<listfiltr>>
[[Unit tests|http://en.wikipedia.org/wiki/Unit_testing]] increase confidence in the quality and reliability of source code.
From release 2.5, The TiddlyWiki core uses the [[QUnit|http://docs.jquery.com/QUnit]] framework (gradually transitioning from [[JSSpec|http://jania.pe.kr/aw/moin.cgi/JSSpec]]).
The [[test suite|http://trac.tiddlywiki.org/browser/Trunk/core/test/recipes/tests.html.recipe]] [[Dev:Recipe|recipe]] provides a simple way to get started.
Individual tests are located in the [[tests directory|http://trac.tiddlywiki.org/browser/Trunk/core/test/tests/]].
These tests can also be see in action in the @test space
!Description
The [[version]] macro displays the version of a TiddlyWiki.
{{annotation{
''Note:'' Old TiddlyWiki versions can be found in the [[Archive]].
}}}
!Usage
{{{<<version>>}}}
<<version>>
Unless you're delighted with the default theme you can make some quick changes by generating a new random color palette, hit this button to cycle through some alternatives.
<<RandomColorPaletteButton saturation_pale:0.67 saturation_light:0.53
saturation_mid:0.43 saturation_dark:0.06 pale:0.99 light:0.85 mid:0.5 dark:0.31>>
You can also change the look and feel completely by installing a new theme. To do this, find one you like in the @themes space, note down the name, and include it in this space by going to the space menu. You can reach the space menu by clicking on the blue and pink circle at the top-right of the page and chooshing "THIS SPACE". Here are a few to check out:
* @pip
* @caspian-ii
* @basalt
* @simplicity
* @cheesecake
* @jelly-doughnut
(//Note that if you are using a custom TiddlySpace install, these themes may not be present.//)
[[TiddlyHoster|http://hoster.peermore.com]] provides TiddlyWeb based hosting for your [[tiddlers|Tiddler]]. It provides more flexibility than TiddlySpace in terms of access control which, however, it does not live up to in terms of presentation and user engagement.

Assume, there is a tiddler called ''"""Some Tiddler"""'' containing the following text...
{{{
!Section 1
Some introductory text.
!!Section 1.1
Some more details.
}}}
Here, the section ''Section 1'' entails all the content up until heading ''Section 1.1''.
You can [[reuse|Transclusion]] the content of ''Section 1'' using the [[tiddler macro|tiddler]]:
{{{
<<tiddler "Some Tiddler##Section 1">>
}}}
Displayed as:
<<<
Some introductory text.

There are a lot of interesting people using ~TiddlySpace that you might like to keep track of and interact with. There are a number of ways of doing this.
If you see a number in the speech bubble in one of your tiddlers, it means that someone is writing about the same thing as you. You can find out what they're saying by clicking on it. Likewise, if you see something interesting in someone else's space, you can respond to it and write up your own thoughts on the subject by clicking "Reply to this tiddler".
Additionally, if you find anyone interesting, or you find an interesting looking space and you'd like to know when it's changed, you can "follow" that space. To do this, simply create a tiddler with the title: {{{@space-name}}} and tag it {{{follow}}}. If you want, you can store some notes about that space in the body of the tiddler.
If you then want to know what happening, simply [[include|How do I include/exclude spaces?]]@docs the @tivity space and then visit your activity stream at [[/activity|/activity]], or just visit the @tapas space directly.
!Not sure who to follow?
Here's a few suggestions:
* @fnd
* @cdent
* @pmario
* @bengillies
* @dickon

[[StyleSheetTiddler]]
In a standard TiddlyWiki, can edit the UserName in the OptionsPanel in the right sidebar.
However, if you rather want this in a custom tiddler of your own, use the [[option]] macro, e.g.:
{{{
UserName: <<option txtUserName>>
}}}
UserName: <<option txtUserName>>
<<tiddler EVAL>>
If you want to display your UserName, see [[How can I display my UserName somewhere?]]...
!Functions
<<list filter [startsWith[title,Wikifier.]][sort[title]]>>
!Global methods
;[[getParser()]]
:selects the correct formatter for a tiddler
;[[wikify()]]
:creates a ''wikifier'' object and then calls [[wikifier.subWikifyUnterm()]]
;[[wikifyStatic()]]
:returns the html directly
;[[wikifyPlain()]]
:calls [[wikifyPlainText()]] on a single tiddler
;[[wikifyPlainText()]]
:calls [[wikifyPlain()]] on the text
;[[highlightify()]]
:calls [[wikifier.outputText()]]
!Static methods
The ''Wikifier'' object constructor takes a formatter. [[getParser()]] figures out which one. [[config.parsers()]] is examined but is empty by default, which means that in the default setup, calls to [[getParser()]] return the global formatter object.
;[[wikifier.wikifyPlain()]]
:calls [[subWikify()]] on itself
;[[wikifier.subWikify()]]
:calls either [[wikifier.subWikifyTerm()]] or [[wikifier.subWikifyUnterm()]] depending on whether it has a terminator provided or not (see below).
Example uses are in the gradient macro's handler, where it is called with a terminator, and [[wikifier.wikifyPlain()]] where it is called without.
;[[wikifier.subWikifyUnterm()]]
:gets called by [[wikify()]] and [[wikifyStatic()]], [[wikifyPlain()]] and [[wikifyPlainText()]] calls [[wikifier.subWikify()]] with one argument, so that ends up calling [[wikifier.subWikifyUnterm()]] as well
The function finds the strings that match with the formatter, outputs whatever is before the first as ordinary text, then goes into a loop through the matches until they run out. The mechanism for figuring out which part of the formatter and therefore which handler to call depends on the result of an exec() call being an array where the elements correspond to the paranthesized parts of the regex - if there is a match, that element contains something in it, if not, it is undefined.
After the matches are finished, it outputs the rest of the text. The handlers tend to wikify their contents, so the wikification process is recursive. The upshot of this is that care has to be taken to keep the regex's lastIndex property and the output pointer in check.
;[[wikifier.subWikifyTerm()]]
:is similar to [[wikifier.subWikifyUnTerm()]]. It takes a terminator regex to match the end of the string in question and wikifies (again a use of recursion) whatever is in between a formatter match and a terminator match.
;[[wikifier.outputText()]]
:outputs text without wikifying it. Copes with highlighting text (via highlightify).

This function is the main entry point for wikification.
It chooses between [[wikifier.subWikifyTerm()]] and [[wikifier.subWikifyUnterm()]] depending upon whether a terminator was passed into the function or not.
!Arguments
;output
:the object to output into
;terminator
:a regexp that defines the end of the block, e.g. ''}}}'' being the end of a code block.
It does not return anything, but rather, renders HTML directly into the output object.

!Summary
This function of the <<tag Array "array class">> returns the index of a given element in an array.
!Signature
{{{Array.prototype.indexOf = function(item,from) {} }}}
!Returns
integer: the index of an element in an array
!Arguments
;1. item
:the item to find the index for
;2. from
:the array in which to find the item
!Example
{{{
var el = "Foo",
arr = ["Foo","Bar"];
return arr.indexOf(el);
}}}
''returns:'' integer: 0
//{{{
config.macros.references = {
handler: function(place, m, p, w, pa, tiddler) {
if(!tiddler) return;
else invokeMacro(place, "list", "filter \"[linksTo[%0]]\" emptyMessage:'No references'".format(tiddler.title), null, tiddler);
}
};
//}}}
As of version 2.6.5, TiddlyWiki can save options permanently -- in addition to the ability to save options in cookies. Persistent options are stored in the shadow tiddler called [[SystemSettings]] which need to create manually.
For example, the option {{{chkAnimate}}} is currently stored as a cookie. To make it option persistent add it to your SystemSettings tiddler:
<<<
chkAnimate: true
<<<
''Note:'' It can still be changed using the OptionsPanel in the sidebar.
The names of all available options can be found in the shadow tiddler called AdvancedOptions.
{{annotation{
!Important
An even more flexible and powerful option is to use a [[zzConfig]] type of tiddler. For details, see [[Changing Default Options]].
}}}
!!Under The Hood
TiddlyWiki uses a JavaScript object to store options from SystemSettings, e.g.
{{{
config.optionsSource {
chkAnimate: "setting",
chkAutoSave: "setting"
// etc...
}
}}}
Each option can take two values...
;null
:» the option is stored in a cookie (default)
;setting
:» the option is stored in SystemSettings
!Descriptions
The [[toolbar macro|toolbar]] is used in the shadow tiddlers called ViewTemplate and EditTemplate to render the corresponding toolbar for view mode and edit mode.
!Usage
in EditTemplate:
{{{
<div class='toolbar'
macro='toolbar [[ToolbarCommands::EditToolbar]]'>
</div>
}}}
in ViewTemplate:
{{{
<div class='toolbar'
macro='toolbar [[ToolbarCommands::ViewToolbar]]'>
</div>
}}}
Use the shadow tiddler called ToolbarCommands to define the commands to be displayed in a corresponding toolbar.

!!TiddlyWiki in ten seconds...
[[by TomO from d³|http://dcubed.com/#TiddlyWiki]]
;10...
:TiddlyWiki is a web-based [[wiki|http://en.wikipedia.org/wiki/Wiki]] that has a very rich Javascript runtime built into every page. If you are reading a TiddlyWiki document, you have the //entire// TiddlyWiki application, in addition to all the "articles" that make up the wiki itself.
;9
:The "articles" within a TiddlyWiki are called ''tiddlers'', and they are saved with the main HTML page used to view the document. If you open a TW document, you can see all the tiddlers saved at the bottom of the file.
;8
:When you view a TW document over the web, you are usually prohibited from making changes. For interactive, modifiable documents like this one, you typically need to save the document locally to your machine and work with it there.
;7
:Tiddlers can be referenced by their name but, more importantly, they can be arbitrarily ''tagged'' to categorize them. Tags may be freely modified, and there are numerous interface widgets within TW to list or find tiddlers by their tags.
;6
:When you click on an internal hyperlink to a tiddler, it will usually open up directly above or below the tiddler you are currently reading and should scroll immediately into view.
;5
:When you hover your mouse over a tiddler, a small context-sensitive ''tiddler menu'' appears above and to the right of the tiddler. One of the important items in this menu is ''edit'' (or ''view''), which allows you to view and modify the source for a tiddler.
;4
:Tiddler source is a combination of just plain text, plus special formatting commands in ''wiki-text'' that allow you to express style and layout for tiddlers without knowing any HTML. It is important to know that the formatting commands, tiddler menus, and just about everything else can be arbitrarily extended by third-party ''plug-ins'' to create custom solutions like this one.
;3...2...1
:That is it in a nutshell, but if you are still feeling a little lost, try this [[tutorial|http://www.blogjones.com/TiddlyWikiTutorial.html ]]
!Summary
By default, the TabTimeline shadow tiddler defines the contents of the {{{Recent}}} tab in the [[Sidebar]] and calls the [[list macro|list]] which outputs all tiddlers in your TiddlyWiki in reverse chronological order.

!Optimization
Listing all tiddlers may not prove practical or desireable. [[TiddlyWiki.org demonstrates|TabTimeline]] how you can shorten the list only to display a full [[timeline]] elsewhere,

Attempting to close or refresh the page, your browser may display the following warning:
{{{
WARNING! There are unsaved changes in TiddlyWiki.
Choose OK to save.
Choose CANCEL to discard.
}}}
This message may be provoked when saving failed due to losing connection to the server when the [[user|User]] is...
* offline
* experiencing a bad network connection
* faced with an [[Edit Conflict]]
Clicking <<saveChanges>> in the sidebar of a standard TiddlyWiki will cause any unsaved changes to be pushed to the server.
The notification mechanism is provided by the TiddlyWiki store object
to enable interested parties to register callback functions to be
invoked when tiddlers are modified. Callbacks can be registered to be
called for modifications to particular named tiddlers, or to be called
for modifications to any tiddler.
To register new callback functions one should make use of the [[addNotification method|TiddlyWiki.prototype.addNotification]]
Out of the box, the notification table looks like this (see Refresh.js
in the TiddlyWiki source repository):
{{{
config.notifyTiddlers = [
{name: "StyleSheetLayout", notify: refreshStyles},
{name: "StyleSheetColors", notify: refreshStyles},
{name: "StyleSheet", notify: refreshStyles},
{name: "StyleSheetPrint", notify: refreshStyles},
{name: "PageTemplate", notify: refreshPageTemplate},
{name: "SiteTitle", notify: refreshPageTitle},
{name: "SiteSubtitle", notify: refreshPageTitle},
{name: "ColorPalette", notify: refreshColorPalette},
{name: null, notify: refreshDisplay}
];
}}}
Note that these notification handlers are called while TiddlyWiki is
starting up and the store is being loaded from the HTML payload in the
document. Quite a lot of care is taken in the core to make sure that
this doesn't trigger double initialisation (where the main() function
explicitly initialises something that is also re-initialised inside a
notification handler).
The notification table is a global variable. It would be more correct
for each instance of the TiddlyWiki store object to have it's own
notification handler table.
One of the problems with the naivety of the notification mechanism is
that it can be quite noisy; if a piece of code is modifying a bunch of
tiddlers the torrent of notifications triggered can slow things down.
To resolve this, the TiddlyWiki object provides methods to temporarily
[[suspendNotifications()|TiddlyWiki.prototype.suspendNotifications]] and [[resumeNotifications()|TiddlyWiki.prototype.resumeNotifications]]. The core uses this
to improve the performance of the importTiddlers macro by suppressing
notifications as individual tiddlers are imported and issuing a
blanket notification at the end of the import.

!Summary
This prototype function of the [[TiddlyWiki.class]] ties an external function, refered to as a ''callback'' to a tiddler. Whenever that tiddler is changed, the callback function is invoked. TiddlyWiki passes the title of the changed tiddler to the callback function.
!Signature
{{{TiddlyWiki.prototype.addNotification = function(title, fn) {} }}}
!Returns
''object:'' store
!Arguments
;1. (string) title
:the title of the tiddler being watched
:when null (not empty string) the callback function is invoked for every tiddler, but only if either:
:* notifications are running via [[store.notifyAll()]]
:* the notify() is called with the second parameter set to true
;2. (function) fn
:the callback function called on any changes
!Example
{{{
store.addNotification('MyConfig','config.extensions.foo.watchConfigChanges);
}}}
''returns:'' the store object

[[Category:FAQ]]
[[Category:Getting Started]]
Certain tags in TiddlyWiki are predefined and have a special meaning...
| !System Tag | !Usage |h
|<<tag systemConfig>>|usually usually [[Plugins]] or [[Macros]], these tiddlers contain executable JavaScript code executed on startup and on demand|
|<<tag systemConfigDisable>>|a deaktivated [[plugin|Plugins]] that is not executed on startup -- takes precedence over ''systemConfig'' and ''systemConfigForce''|
|<<tag systemConfigForce>>|force [[plugins|Plugins]] to be executed on startup irrespective of dependencies to a given ''CoreVersion'' or other plugins|
|<<tag systemServer>>|a tiddler which contains server details for [[Import]]|
|<<tag systemTheme>>|a tiddler that is a [[Theme|Themes]]|
|<<tag excludeSearch>>|a tiddler excluded from search results|
|<<tag excludeLists>>|a tiddler excludes from lists in the sidebar tabs (e.g. [[Timeline]]) as well as from the generated RSS feed|
|<<tag excludeMissing>>|a tiddler that wont appear in the sidebar under ''More'' / [[Missing|TabMoreMissing...]]|
@@Please do not modify this tiddler; it was created automatically upon space creation.@@
Runs various <<tag refresh>> functions
It refreshes the PageTemplate, the display and the default stylesheets StyleSheetLayout, StyleSheetColors, StyleSheetPrint and the active stylesheet (usually StyleSheet but defined in the javascript variable config.refresherData.styleSheet)
The [[core|Core]]@tiddlywiki refers to the javascript that comes with a standard TiddlyWiki. The following topics provide inside knowledge in core processes...
<<get ##Summary filter:[tag[Core]] table>>
!"""Wiki Markup"""
Sometimes text can match TiddlyWiki formatting whether you want it to or not, e.g. program code, or conted pasted from elsewhere. To avoid this see section ''Avoiding Wikification'' in [[TiddlyWiki Markup]]...
!Code Comments
Individual tiddler passages can be "commented out" to prevent them from being processed and/or displayed by TiddlyWiki:
[cf. http://oldwiki.tiddlywiki.org/wiki/Escaping / http://oldwiki.tiddlywiki.org/wiki/Dev:Comments]
!Summary
Use the shadow tiddler WindowTitle to define the text you wish displayed as the window title of your TiddlyWiki in the the browser.
!Default Contents
{{{
<<tiddler SiteTitle>> - <<tiddler SiteSubtitle>>
}}}
This then displays something like...
{{{

}}}
You can change this at any time. For example:

Lately I found the version number changed from 2.6.2 to 2.6.3
But trying to upgrade the 2.6.2 version by backstage/upgrade does not work, it ends in displaying "Error with the new core code". And this error ist displayed not only when I try to upgrade from 2.6.2 to 2.6.3 but even when I try to "upgrade" a fresh and empty version 2.6.3 tiddlywiki. Might it be that there are (wrong?) Firefox configuration settings which prevent it from upgrading tiddlywiki? What am I doing wrong?

!Description
The [[annotations]] helper macro is used in the shadow tiddlers ViewTemplate and EditTemplate to define where annotations are rendered, e.g.:
* the information displayed in view mode when a """tiddler""" does not exist yet
* the information displayed in edit mode for a tiddler that is a shadow tiddler
!Usage
{{{
<div macro='annotations'></div>
}}}
The TiddlyWiki Address Book (twab) is a system for keeping your Address Book within your TiddlyWiki.
It supports the addition of contacts via a simple macro that can be placed in any Tiddler.
It also supports the import and export of your contacts to and from major webmail providers such as Google, Yahoo, and Hotmail as well as Microsoft Outlook. Twab is customizable and comes fully documented.

All you need to run TiddlyWiki is your web browser. Though it must be a reasonably recent browser that supports javascript. Firefox is reported to have the best support, but IE (6 or better), Opera, and Safari are also supported.
If you want to [[Editing and Saving over HTTP|publish your TiddlyWiki]] then you'll need a web host (or a hosting service like the free http://www.tiddlyspot.com).

If it seems like wiki options ("options >>" on the right sidebar) aren't being saved between browser sessions.
Make sure you have cookies enabled because the TW options are saved in cookies.
You can also change the default settings in a tiddler variously called systemconfig, systemsettings, zzconfigoptions. These are tiddlers, not tags.

The content of these tiddlers which have a prefix of {{DEV.}}} are prepended to tiddlers that originate from @TiddlyWiki.
A PermaLink allows you to open TiddlyWiki with a dedicated tiddler or a set of tiddlers.
TiddlyWiki provides two ways to contruct a PermaLink...
;PermaLink Toolbar Button
:» outputs a link in the browsers address bar to open TiddlyWiki with this tiddler
;PermaView Sidebar Button
:» outputs a link in the browsers address bar to open TiddlyWiki with all currently displayed tiddler preserving the order
Martin Budden has created formatter plugins that allow you to use markups other than TiddlyWiki, e.g.:
;MediaWiki Markup
:» [[MediaWikiFormatterPlugin|http://www.martinswiki.com/#MediaWikiFormatterPlugin]]
;More Markup Formatters

!Usage
The viewRevisions macro can be attached to any element, which should be passed
in as a parameter.
For example:
<<viewRevisions page:10 link:"<<view modified date>>">>
would show the revisions "stack of cards" view, 10 at a time, when the modified
date is clicked.

Image hosting sites offer a handful of pre-set sizes (eg thumbnail, small, large). If none suit, here's one method for resizing images within TiddlyWiki.
If using a URL, wrap it in HTML tags and insert '''style="width: 70px; "''' or '''style="height: 146px; "''' (altering the px to desired size) before '''/></html>''' like this:
<nowiki>
<html><img src="url of image" style="width: 70px; "/></html>

TiddlyWiki for the rest of us by Dave G (Also available in Spanish)
Intro: TiddlyWiki is a very versatile program, but has an initial learning curve to it. Much of the documentation is written by and for people immersed day after day in computer code, so, um, how do I put this delicately, it is not always written in helpful everyday language. Not being a computer genius myself, I found the TiddlyWiki learning curve daunting, but well worth it. For those of you like me, newcomers to TiddlyWiki who don't know "Tiddly Squat", I would like you to discover this great program without having to commit as much time and energy to it as I did. Enjoy!

Using the [[newTiddler]] macro you are able to create new tiddlers with predefined contents.
!1. Entering Text Directly
Use the {{{text}}} parameter to provide the desired text for the new tiddler...
{{{
<<newTiddler
label:"New tiddler with text content.."
text:"Some content..."
tag:"NEW!"
>>
}}}
<<newTiddler
label:"New tiddler with text content.."
text:"Some content..."
tag:"NEW!"
>>
!2. """Using A Template Tiddler"""
Use the {{{text}}} parameter and the getTiddlerText function to fetch the template text from a tiddler via evaluated parameters...
{{{
<<newTiddler
label:"New tiddler with template content..."
text:{{store.getTiddlerText("Welcome")}}
tag:"NEW!"
>>
}}}
<<newTiddler
label:"New tiddler with template content..."

'' Slow Rendering ''
In TiddlyWikis with a large amount of tiddlers, the listings in [[SideBarTabs]] (e.g. [[Timeline]]) might require a long time to be generated, thus inhibiting the overall performance.
cf. [[Tips for speeding up performance on large TiddlyWikis|http://www.giffmex.org/twfortherestofus.html#%5B%5BTips%20for%20speeding%20up%20performance%20on%20large%20TiddlyWikis%5D%5D]]
Quote:[[Dave|http://groups.google.com/group/TiddlyWiki/browse_thread/thread/2558268245a93d7a/cec021c6f5b42271?#cec021c6f5b42271]]
I recommend disabling animations even on medium-sized tiddlywikis. Animations slow it down. Also, if your file gets big you will want to open the shadowed tiddler tab rather than the tab listing all tidders A-Z or by date. Or hide the tabbed menus altogether if you don't need them showing. With each new tiddler, the image of the two tabbed lists I mentioned (all and by date) has to be refreshed and can take a while. You can remove the tabbed lists from the page layout by removing their code from PageTemplate. Nevertheless, I have a couple TiddlyWikis with 1,000s of tiddlers that each have form fields, and I am not noting any other performance
issues yet.
'' Plugin Load Times ''
[[Eric|http://groups.google.com/group/TiddlyWiki/browse_thread/thread/38c0b23e4e007c2b/263409bf4f852efd?#263409bf4f852efd]]
The plugin 'load timer' information is available in the shadow tiddler, [[PluginManager]], which is also accessible from the
backstage>plugins menu, or by embedding the <nowiki><<plugins>></nowiki> macro into any tiddler content.
[[Martin|http://groups.google.com/group/TiddlyWiki/browse_thread/thread/38c0b23e4e007c2b/53af6dface09556f?#53af6dface09556f]]
You can also see the total time taken to load the plugins:
1) go to the tweak dropdown in backstage
2) click the "Show unknown options" checkbox
3) click the "chkDisplayInstrumentation" checkbox, it's about the 8th one down
this will let you see what proportion of the total load time is spent loading the plugins
'' Maximum File Size ''
Ken: This seems to be the constant question: How big can it get?
As far as I am aware there is no limit to how big of a file you can download and open. I pumped up a TW to around 3 megs just to see what it could do and didn't have any problems. It took a while to get the file, but I got it.
If you are running lots of plugins then Firefox will give you the "A script is making this page run slow. Do you want to continue?" message, but it will load.

The problems reported by people with large TiddlyWikis are usually performance based, and it seems that the solution (once you've disabled animations..) is to remove macros that loop through every tiddler, like the tabs in the sidebar. So it's not so much the size
that's the problem in a direct sense, but the fact that many TW macros assume that looping through every tiddler isn't very slow.
Markus: Mine is online and loading of about 1.7 MB might be quite annoying for people with low bandwidth. I'm desperately seeking for a solution !

The ~TiddlySaver Java applet allows ~TiddlyWiki to save changes in a local version (from a file:// URL) of Safari, Opera and other browsers. It is a small file named [["TiddlySaver.jar"|TiddlySaver.jar]] that must be placed in the same directory as your ~TiddlyWiki file. As of August 2008, when an empty ~TiddlyWiki file is downloaded using either Safari or Opera, it is bundled with a copy of the ~TiddlySaver.jar file in a zip file - both files must be in the same directory ''whenever the ~TiddlyWiki file is opened'' in order to work.
[["TiddlySaver.jar"|TiddlySaver.jar]] is signed by [[UnaMesa Association|UnaMesa]]. The [[UnaMesa Association|UnaMesa]] certificate is signed by the ''Thawte Code Signing CA'' intermediate certificate which is chained to the ''Thawte Premium Server CA'' root certificate. You need to trust this certificate Chain to be able to use the applet.
Note that there is currently [[a bug|http://trac.tiddlywiki.org/ticket/172]] that prevents ~TiddlySaver from working if you have specified a backup directory in AdvancedOptions and the directory doesn't exist.
Thanks to Andrew Gregory for the original TiddlySaver code, and ~BidiX for arranging all the certificate magic.

!Description
This [[script|Scripts]] allows you to insert the current time.
!Code
{{{
<script label="What time is it?">
return "<br>" + new Date().toString();
</script>
}}}
{{annotation{
''Note:'' A similar result can be achieved using the [[today macro|today]], e.g.:
{{{
''What time is it?''
<<today 0hh:0mm:0ss>>
}}}
''What time is it?''
<<today 0hh:0mm:0ss>>
}}}
The following steps explain how you can setup your TiddlyWiki for use as a public website.
{{annotation{
''Note: ''Due to the nature of Javascript TiddlyWiki generally provides virtually no means to hide what is going on behind the scenes.
}}}
!Read Only Mode
You can add the following to a tiddler called //zzConfig// tagged [[systemConfig|Plugins]]:
{{{
if(config.options.txtUserName != "adminname") {
showBackstage = false;
readOnly = true;
}
}}}
{{annotation{
This plugin is automatically run in the background when TiddlyWiki loads. The prefix zz ensures that this config tiddler is loaded "last" in order to override any previous commands.
}}}
This will achieve the following effects:
;{{{if(config.options.txtUserName != "AdminUserName") }}}
:ensures that read-only mode is only enforced when the UserName set in the options panel is something other than //~AdminUserName//
;{{{showBackstage = false;}}}
:hides the [[Backstage]] area
;{{{readOnly = true;}}}
:displays a different tiddler [[Toolbar]] to the user, i.e instead of an //edit// command you will most often only find a //view// command
In order to edit a wiki in read-only mode, enter the user name in the options panel in the sidebar and reload the wiki. Now you will again be able to use the edit command in the tiddler toolbar. This user name is stored as a cookie in your browser, i.e. you will be logged in for the lifetime of this cookie. No visitor should accidentally view your wiki in edit-mode.
!Hiding The Right Sidebar
In order to hide the right hand side bar for visitors, import the following plugins from [[TiddlyTools]]:
http://www.TiddlyTools.com/#InlineJavascriptPlugin
http://www.TiddlyTools.com/#ToggleRightSidebar
To have the sidebar hidden upon TidlyWiki start, add the following to the aforementioned zzConfig tiddler:
{{{
config.options.chkShowRightSidebar=false;
}}}
{{annotation{
Note: If you put it in the same section that only applies for visitors, you will always see the sidebar whereas your visitors do not.
}}}
Before hiding the right sidebar to your visitors, you should ensure that you can access it yourself by
# simply opening the shadow tiddlers SideBarOptions or SideBarTabs tiddlers, e.g. via yourwiki.html/#SideBarOptions
# creating a hidden or hardly visible element that allows you to toggle the sidebar
#* you could append the following to the shadow tiddler SiteSubtitle {{{<<tiddler ToggleRightSidebar with: ".">>}}}
#* the dot thus added to the subtitle of your TiddlyWiki will now allow you to toggle the sidebar
!!Different Toolbar For Web Users
If you want diffenent toolbars, including the possibility to turn off double-clicking to edit, please see..
[[How do I have a different tiddler toolbar for web users?]]
!Showing One Tiddler At A Time
To enable single-page mode as in most normal web pages...
#import [[SinglePageModePlugin|http://www.TiddlyTools.com/#SinglePageModePlugin]]
#add {{{config.options.chkSinglePageMode= true;}}} to your zzConfig
!Admin Tools
For quick access to admin features, you can add {{{<<tiddler Admin>>}}} to the shadow tiddler SideBarOptions for quick acces to your most needed features and then create a tiddler called //Admin// containing things like...
;{{{<<option txtUserName>>}}}
:enter your username
;{{{<<upload http://yoursite.tiddlyspot.com/store.cgi index.html . . yoursite>>}}}
:upload your TiddlyWiki hosted on TiddlySpot using UploadPlugin
;[[zzConfig]]
:access and modify your zzConfig
The functional side of TiddlyWiki is entirely implemented using JavaScript while the [[HTML]] provides the structure and [[CSS]] the design, all of this in a single, dynamic wiki.

'' Problem ''
When you type a bunch of spaces into your TiddlyWiki, they look ok until you save and reload. Then any run of multiple spaces have been replaced with an single space. This also affects tab characters so it's especially nasty for plugins and code snippets. All your indenting gets trashed.
'' Solution ''
This only happens in Microsoft Internet Explorer. When IE stores tiddlers it replaces a set of spaces with a single space. There is no simple solution apart from switching to a different browser, such as Mozilla Firefox.
Also I believe the problem is fixed in 2.2 (currently in beta).
'' Guess Again ''
It happens in Firefox 2, TiddlyWiki 2.4.0.
And In Firefox 3. Hopefully there's a better solution than using &nbsp;
'''temporary note'''
Using [[preformatted blocks|TiddlyWiki Markup#Preformatted]] should solve this issue.
However, even without those, it seems to work fine with TiddlyWiki v2.4.1 and both Firefox 3 and IE7 on Windows Vista.
-- [[User:FND|FND]] 07:00, 28 August 2008 (UTC)
----
I just upgraded to 2.4.1 and spaces are not preserved for me. I run TiddlyWiki in Firefox 3 on Vista

See [[Finding A Tiddler]]...
A TiddlyWiki file must be saved or served using [[UTF-8 Encoding|http://en.wikipedia.org/wiki/UTF-8]].
!"""Serving TiddlyWiki"""
If you are serving TiddlyWiki using a web server you may need to add a ''.htaccess'' file containing:
{{{
AddCharset utf-8 .html
}}}
!"""Saving TiddlyWiki"""
If you """edit""" the source of TiddlyWiki directly in a text editor, make sure that it can handle UTF-8 and is set to use it, otherwise it might save TiddlyWiki using [[ASCII Encoding|http://en.wikipedia.org/wiki/ASCII]] or [[Latin Encoding (IEC 8859-1)|http://en.wikipedia.org/wiki/ISO/IEC_8859-1]] which will break special characters such as the » character in ''"""options """»''.
Want to embed an iFrame into TiddlyWiki? See [[HTML Formatting]]...
! Be Bold!
Contributions to the wiki are always welcome. If you ever come across information that you think is useful to a larger audience, feel free to add it to the wiki.
Don't worry if you're not sure about details like page title or categorization - this is a wiki, so chances are others will take care of those issues as they find them.
! Editing Guidelines
Anyone who is a member of TiddlySpace has the power to edit in this space.
! Page Names
Page names should generally be concise (e.g. "Customization" or "Customizing" instead of "How to customize TiddlyWiki.").
!! Capitalization in Titles
# Always capitalize the first and the last word.
# Capitalize all nouns, pronouns, adjectives, verbs, adverbs, and subordinate conjunctions ("as", "because", "although").
# Lowercase all articles, coordinate conjunctions ("and", "or", "nor"), and prepositions regardless of length, when they are other than the first or last word.<br>Capitalize prepositions of five characters or more ("after", "among", "between").
# Lowercase the "to" in an infinitive.

!Summary
Returns the plain text version of wikitext, i.e. strips the markup and returns just the text.
!Signature
{{{Wikifier.prototype.wikifyPlain = function(){} }}}
!Returns
string: the text representation of wikitext
!Arguments
none
!Example
{{{
var markup = 'I like //italics//.'
wikifyPlain(markup);
}}}
''return:'' 'I like italics.'
!How It Works
This function wikifies the markup into a hidden <div> using the [[Wikifier.prototype.subWikify()]], and calling [[getPlainText()]] on the hidden <div>. It then removes the hidden div and returns the text.
{{annotation{
''Note:'' this does not return html.
}}}
To permanently save a [[tiddler|Tiddler.class]], TiddlyWiki needs to be saved in its entirety.
{{annotation{
''Note:'' While the above is true in a classical TiddlyWiki, this is not so in many [[Server-Side Solutions]]@tiddlywiki for TiddlyWiki, such as [[TiddlyWeb]]@TiddlyWiki (or TiddlySpace@TiddlyWiki respectively) where edits on tiddlers are saved individually, including a check for [[Editing Conflicts]]@tiddlywiki.
}}}
The ''isDirty'' method of a [[TiddlyWiki class|TiddlyWiki]] object returns whether there are unsaved changes to it. This method expects no parameters.
Use:
{{{
store.isDirty();
}}}

!Summary
By default, the TabMoreShadowed shadow tiddler defines the default contents of the {{{Shadows}}} tab in the [[Sidebar]] and calls the [[list macro|list]] which outputs a list of all shadow tiddlers, e.g. tiddlers with predefined fallback contents.
!Default Contents
{{{
<<list shadowed>>
}}}
[[Macros]] provide dynamic functions in TiddlyWiki.
<<slider chkCoreMacrosOverview Macro##CORE "Core Macros" "Click to see a list of all core macros..." >> are disitributed with a standard TiddlyWiki -- many more macros are provided by third-party plugins.
Macros are executed when the tiddler containing the macro call is rendered. To use a macro, simply add it in your wikitext using the following markup:
{{{<<macroName [parameters]>>}}}/%
!CORE
Her's a list of all [[Core Macros]] and their description...
<<get ##Description filter:"[tag[Core Macros]][sort[title]]" table category:Macro>>
!END%/
!Description
This macro outputs a list of all tags in this TiddlyWiki whereas clicking on a tag opens a popup listing all tiddlers for the corresponding tag. Compare to [[tag]] macro.

This term is introduced in [[wikipedia|http://en.wikipedia.org/wiki/Transclusion]] as:
> In computer science, transclusion is the inclusion of a document or part of a document into another document by reference.
In TiddlyWiki, the tiddler macro can be used to embed the entire content, sections or slices of one tiddler into another tiddler.
!!"""Parametric Transclusion"""
Using the {{{with:}}} parameter in the tiddler macro, placeholders {{{$1..$9}}} in the transcluded contents are replaced with the specified value.
!!!Example
''Tiddler: Prince Hamlet''
{{{<<tiddler [[QuoteTemplate]] with: "Alas poor Yorick" "Shakespeare">>}}}
''Tiddler: ~QuoteTemplate''
{{{
<<<
$1
<<<
{{{$2}}}
}}}
Using the [[tiddler macro]] as in the tiddler ''Prince Hamlet'' above the output will be...
<<<
Alas poor Yorick
<<<
{{{Shakespeare}}}
!!!"""Editing Transcluded Contents"""
* [[TiddlerWithEditPlugin|http://tiddlywiki.squize.org/#TiddlerWithEditPlugin]] adds "double-click to edit source" capabilities to the core Tiddler macro
* [[EditTiddlerPlugin|http://www.tiddlytools.com/#EditTiddlerPlugin]] embeds an "edit" link in tiddler content to invoke edit on any specified tiddler title
!!"""StyleSheet Transclusion"""
In StyleSheet tiddlers, the following references are treated like import statements; whereas the contents of the referenced tiddler, section or slice is included as [[CSS]] code:
;tiddler
:» {{{[[Tiddler Title]]}}}
:» imports the entire tiddler
;section
:» {{{[[Tiddler Title##Some Section]]}}}
:» imports a tiddler section
;slice
:» {{{[[Tiddler Title##Some Section}}}
:» imports a tiddler slice
!!"""Transcluded HTML Scripts"""
(from Eric in [[google group|http://groups.google.com/group/tiddlywiki/browse_thread/thread/c4aa71ecb0f7d4cf/7e2272e3bc4593eb?#7e2272e3bc4593eb]])
{{{
Transclusions can be used generate program- driven output, embedded in specific
tiddler content (like an inline script or a plugin-defined macro).
Transclusions are invoked by using the
<<tiddler TiddlerName with: param param param ...>>
syntax. The 'param' values are automatically inserted in place of
any 'substitution markers' ("$1" through "$9") that are embedded in the
transcluded content. This allows you to use the transclusion as if it was a
macro function: passing in parameter values and generating enhanced output in
response.
Some transclusions are simple substitutions, allowing you to use an abbreviated
syntax to render pre-formatted blocks of content, like this:
<<tiddler ShowQuotation with: [[...quote...]] [[author]]>>
where ShowQuotation contains:
$2 wrote:
{{{
$1
}}}
Transclusions can do much more than simply insert a few values into a
pre-defined format. By using a combination of 'hidden sections' and some
cleverly written 'evaluated parameters' invoked from the <<tiddler>> macro, it
is possible to build some complex programmed behaviors
into a transcluded tiddler.
However, while macros and inline scripts can use virtually any javascript coded
logic you can imagine, transclusions only contain standard TW syntax, without
relying upon installation of any supporting plugins (i.e.,
InlineJavascriptPlugin). Although this limits their abilities somewhat, there
are still a wide variety of programmatically-generated output and/or behaviors
that they can produce.
In fact, when possible, I have been converting many of my previously written
TiddlyTools inline scripts into 'transclusions', in order to completely
eliminate their dependence on InlineJavascriptPlugin. By using only TW native
syntax, it allows these former scripts to work properly and consistently,
regardless of whether they are installed in an empty TW document or one that
has been highly customized with lots of plugins.
For the current listing of 'transclusions' available on TiddlyTools, see:
http://www.TiddlyTools.com#txtCatalogTab:transclusions

A standard TiddlyWiki comes with a number of predefined [[shadow tiddlers|ShadowTiddler]] interpreted by TiddlyWiki as cascading style sheets, aka [[css|http://www.w3schools.com/css]]. These include...
| !Shadow Tiddler | !Description |h
|[[StyleSheetColors]] |default color styles |
|[[StyleSheetLayout]] |default layout styles |
|[[StyleSheetLocale]] |locale-specific styles |
|[[StyleSheetPrint]] |default print styles |
|[[StyleSheet]] |the tiddler for your custom styles; run after all others|
''Note'': The color scheme of a TiddlyWiki is defined using [[Slices]] in the shadow tiddler called [[ColorPalette]].
Like all shadow tiddlers you can simply overwrite the default styles provided by these StyleSheets or add them if your customizations went awry.
Some plugins also provide default styles in the form of a shadow tiddlers whose names usually begin with [[StyleSheet]] followed by he name of the plugin.

!Summary
By default, the TabMoreMissing shadow tiddler defines the contents of the {{button{Missing}}} tab in the [[Sidebar]] and contains a call to the [[list macro|list]] which outputs all tiddlers that have links to them but are undefined.
!Default Contents
{{{
<<list missing>>
}}}
Filters used by [[store.filterTiddlers()]] follow a grammar that can be described using http://en.wikipedia.org/wiki/EBNF:
{{{
filter := filterStep {'|' filterStep }
filterStep := '[' filterElements ']', {'[' filterElements ']'}
filterElements := filterElement, {filterElement}
filterElement := '['TiddlerName']' | tag'['TagName']' | sort'['SortField']' | limit'['NoOfResults']'
}}}
Another way of expressing this, without the (in this case) slightly confusing EBNF syntax, might be:
A filter string is of the form:
{{{
// only one filterStep is required
filterStep | filterStep ...
}}}
where filterStep is of the form:
{{{
// only one filterElements is required
[filterElements] [filterElements] ...
}}}
where filterElements is one or more of the following:
{{{
[TiddlerName]
tag[TagName]
sort[SortField]
limit[NoOfResults]
}}}
!Example
{{{
store.filterTiddlers("[tag[blog post]][sort[-modified]][limit[10]]")
}}}
''returns:'' any tiddler tagged "blog post", limited to the 10 most recently edited tiddlers.
!Allowed types of filterElement
|filter|meaning|
|[text]|refers to a single tiddler with title "text"|
|{{{[text text]}}}|refers to a single tiddler with title "text text"|
|tag[tag]|refers to any tiddler tagged with "tag"|
|tag[a tag]|refers to any tiddler tagged with "{{{[[a tag]]}}}"|
|sort[+field] or [sort[field]]|sorts any results already collected in ascending order by "field"|
|sort[-field]|sorts and results already collected in descending order by "field"|
|limit[integer]|limits the results array to contain no more than "integer" tiddlers|
!Multiple filterElements and filterSteps
#Multiple ''filterElements'' are combined by concatenating the results from each ''filterElements''.
#Multiple ''filterStep'', on the other hand, are evaluated in succession, with the results of each ''filterStep'' used as the tiddler set for the next ''filterStep''.

By default, the shadow tiddler PluginManager contains nothing but the command to display the plugin manager.

If a dom element has a refresh attribute that matches a definition in config.refresher it will run the corresponding refresh functions
by default there are refreshers for "link", [[tiddler|config.refreshers.tiddler]], "content" and "macro"
[[five.tiddlywiki.com|http://five.tiddlywiki.com]] -- the next generation TiddlyWiki, currently under heavy development, leveraging [[HTML5]]
<<tiddler Images>>
TiddlyWiki's architecture for interacting with servers allows it to be plugged into a wide variety of servers.
This is done through the addition of plugins containing custom server adaptors.
Server adaptors are designed to allow for UseCases like importing tiddlers, loading missing tiddlers on the fly and synchronizing changes with a server.
Separate macros and core extensions implement such features by accessing the facilities provided by server adaptors.

A DOM reference points to an element in the DOM.
[[Bag]] is a name used in TiddlyWeb for a collection of uniquely named [[tiddlers|Tiddler]].
Each [[bag|Bag]] has a separate [[Policy]] for [[Access Control]] by [[Users|User]]. A bag may also have a description field, typically containing text stating the purpose of the bag.
A TiddlySpace [[space|Space]] has a pair of [[Public]] and [[Private]] bags. [[Users|User]] can create additional bags for a [[space|Space]] and manage the corresponding policies via the [[TiddlySpace API]].
The SiteInfo tiddler is a special [[tiddler|Tiddler]] that can be used to provide a public description on [[space|Space]].
It can just contain text but also tags and [[extended fields|Custom Fields]]. It is designed to describe a space to a newcomer and to be used by plugins.
For example, a space tagged ''"""plugin"""'' will be listed as a plugin space, one called ''"""theme"""'' will be listed as a theme space.
The idea behind its conception was first discussed [[here|http://groups.google.com/group/tiddlyweb/browse_thread/thread/34e6ac1ef870c7e6]].
[[Welcome]]
Tiddlers hidden from default lists:
{{fancyTimeline{

}}}
Either in the context of [[changing the default date formats|How do I change the default date formats for core macros?]] for core [[macros|Macros]] like [[today]], [[newJournal]], [[timeline]] and [[view]] or by using the corresponding date format parameters you can define a combination of ordinary text and special ''patterns'' substituted that will eventually with formatted with date values:
|!Pattern|!Description|!Example|
|{{{DDD}}}|weekday as text|<<today DDD>>|
|{{{ddd}}}|weekday as short text|<<today ddd>>|
|{{{DD}}}|day of month|<<today DD>>|
|{{{0DD}}}|day of month w/ leading zero|<<today 0DD>>|
|{{{DDth}}}|day of month w/ suffix|<<today DDth>>|
|{{{WW}}}|week number, see [[ISO-8601|http://de.wikipedia.org/wiki/ISO_8601]]|<<today WW>>|
|{{{WW}}}|week number w/ leading zero|<<today 0WW>>|
|{{{MMM}}}|month as text|<<today MMM>>|
|{{{mmm}}}|month as short text|<<today mmm>>|
|{{{MM}}}|month as number|<<today MM>>|
|{{{0MM}}}|month as number w/leading 0|<<today 0MM>>|

From the [[Glossary|WikiWord]]...
<<<
<<tiddler WikiWord>>
<<<
In conventional wikis, this notation is also referred to as [[CamelCase|http://en.wikipedia.org/wiki/CamelCase]] and used to name individual pages. Used in the content, a WikiWord automatically creates a link to the page called WikiWord. Clicking such a link opens that page or -- if it doesn't exist yet -- an editor to create it.
A standard TiddlyWiki uses WikiWords as titles, especially for predefined [[shadow tiddlers|ShadowTiddler]].
!!"""Disabling WikiWords"""

Someone has tagged a tiddler tagging here for review...
Check tiddlers with the tag <<tag DELETE>> for deletion...
/***
|''Name''|ImageMacroPlugin|
|''Version''|0.9.4|
|''Description''|Allows the rendering of svg images in a TiddlyWiki|
|''Author''|Osmosoft|
|''License''|[[BSD|http://www.opensource.org/licenses/bsd-license.php]]|
|''Notes''|Currently only works in modern browsers (not IE)|
|''Requires''|BinaryTiddlersPlugin|
!Usage
{{{<<image SVG>>}}} will render the text of the tiddler with title SVG as an SVG image (but not in ie where it will fail silently)
!!Parameters
width/height: specify width/height parameters
link: make the image link to a given location
tiddlyLink: link to a tiddler
!Notes
Binary tiddlers in TiddlyWeb when passed through the wikifier will be shown as images.
eg. {{{<<view text wikified>>}}} on a binary tiddler will show the image.
{{{<<view fieldname image>>}}}
will render the value of the tiddler field 'fieldname' as an image. This field can contain a tid
{{{<<image SiteIcon>>}}}
will create an image tag where the tiddler has content type beginning image and not ending +xml
will attempt to create svg object in other scenarios
{{{<<image /photos/x.jpg>>}}}
will create an image tag with src /photos/x.jpg as long as there is not a tiddler called /photos/x.jpg in
which case it will render that tiddler as an image. Note for the case of svg files it will attempt to render as an svg if possible via the image
tag. It doesn't embed the svg in the dom for security reasons as svg code can contain javascript.

The single-file paradigm was at the heart of the original design of [[TiddlyWiki]]. It therefore was not designed for multi-user collaboration which makes concurrent editing a challenging issue.
However, there are various solutions enabling TiddlyWiki to be used as a collaborative platform.

Server-side solutions for [[TiddlyWiki]] provide ubiquitous access to hosted TiddlyWiki documents, and potentially enable multi-user collaboration on a single TiddlyWiki document.

}}}
This is tiddlywiki.org on the new platform "TiddlySpace".
Some information is already migrated from the old wikipedia but there is still a lot to do.
The old dot-org wikipedia was littered with spam and not well maintained so there are some benefits to move over to the TiddlySpace platform.
# cleanup during migration
# update of the information
# write and display examples in our own markup
''You can also contribute to this wiki!''
To do so, you need to signup for TiddlySpace.
If you signup you will get your own Tiddly"Space"Wiki (your first space-name is also your editor-name) where you can write and publish, private and public tiddlers.
You will also be able to contribute on this @tiddlywiki space. (every TiddlySpace member can).
After you signed-up you can login on TiddlySpace (via your own space or here) and start contributing.
;Some guidelines for this wiki:
* language is English (create other languages in other spaces...you can link them here)
* test/check content before posting
;Things you can do:
* migrate articles from the old wikipedia [[here|http://web.archive.org/web/20101129095145/http://tiddlywiki.org/wiki/Special:AllPages]] (but first please check if the information is still accurate and up to date -- if you are not sure about something, try to test or ask in the [[community forum|The community forum]], and adjust before publishing here)
* write new content
Don't know where to start?
Check your bookmarks in your browser...any links to articles in the old wikipedia? (might be good content!)
Dead links (from everywhere) to articles in the old wikipedia might be an indication that some info is missing here.
or...
...improve this tiddler...
!References
* in [[this google groups discussion|https://groups.google.com/forum/?fromgroups#!topic/tiddlywiki/wAW1pQABu8k]] it was announced to move the [[old MediaWiki documentation|http://web.archive.org/web/20101129095145/http://tiddlywiki.org/wiki/Special:AllPages]] here to TiddlySpace.
;Situation:
You have a TiddlyWiki file on your pc and want to share this as a website online. (by sending or linking the web-address (the "url"))
Meanwhile you also want to edit the same TiddlyWiki local and add content.
;One of the options is Dropbox
Dropbox is a cloudservice that can be used for synchronizations of folders between pc's.
The Dropbox functionality can both be used via a website and installed on you local computer (both Mac, Windows and Linux)
In the following guide you need to have Dropbox installed on your pc! (see ''Dropbox installation'' below)
Dropbox has many great features like sharing folders between users and other pc's...this guide will __only__ cover the usage of the ''public'' folder and TiddlyWiki to publish your local TiddlyWiki.
!!!Step 1
*Go to Dropbox and sign-up for an account.
*Download Dropbox and install it on your computer.
*Finish the installation settings so Dropbox is attached to the account you created.
!!!Step 2
*You will now have a Dropbox folder on your pc (depending where you installed it.. homefolder or desktop (all is ok))
*Inside the Dropbox are a number of pre-created folders.
!!!Step 3
*Open the "Public" folder inside the Dropbox-folder and create a folder ("tw" for example).
*Put (copy-paste or drag) a TiddlyWiki inside the "tw" folder you just created.
!!!Step 4
*Visit the Dropbox service online and login.
(now you can see the same document structure similar to your local Drobox folder)
*Go to the "Public" folder and open the "tw" folder you just created locally.
(since Dropbox synchronizes with your local folder the new "tw" folder should be there)
*Open the "tw" folder and locate the TiddlyWiki.
*The dialog (arrow on the right side) will give you the option for delete, move etc.
''The "public-url" is the link to your TiddlyWiki file over the internet.''
//(example image "copy public url")//
[img[dropbox.png]]
!!!Step 5 (the test)
Edit your local TiddlyWiki and check (reload page) the public url to see the changes.
!!!Dropbox installation
Visit this url: https://www.dropbox.com to sign-up for the service and to download Dropbox for local installation.
Watch the video to see more features about Dropbox.
!!!Downside of Dropbox urls
It is not possible to have nice domain-names instead of the Dropbox url's.
Your TiddlyWiki's will allway's have url's similar to:
{{{
http://dl.dropbox.com/u/YOUR_NUMBER/tw/empty.html
}}}
!!!Tip
Many TiddlyWiki users have a Dropbox to publish and share so called "minimal testcases" (MTC's) in the googlegroups (TiddlyWiki's where the "private" content is stripped of...only showing an issue)...so they can easily share ideas or issues.
Most wikis provide a simple syntax for editing structured wiki content as plain text based on a [[markup|TiddlyWiki Markup]] that is considerably simpler than that of HTML.
<<tiddler Wikification>>
Examples for wiki syntax are...
* [[TiddlyWiki Markup]]
* [[MediaWiki Markup|http://www.mediawiki.org/wiki/Help:Formatting]]
* [[Markdown Syntax|http://daringfireball.net/projects/markdown/syntax]]
*etc...
!"""Formatter Plugins"""
A number of formatter plugins allow you to use other markup languages and can be found here:
* [[Martin Budden's formatters|http://svn.tiddlywiki.org/Trunk/contributors/MartinBudden/formatters]] also on [[marginswiki.com|http://www.martinswiki.com/#Plugins]]
* [[FND's Formatters|http://svn.tiddlywiki.org/Trunk/contributors/FND/formatters]]

}}}
''Answer''
TiddlyWiki is a little different to other Wikis you may have encountered before. Most wikis run on a server and the code to save your changes is server code. TiddlyWiki is different. It runs entirely in your web browser. All the code to save your changes is written in Javascript and contained in the TiddlyWiki file. To save changes your browser must be able to write to local disk using javascript. This means you can only edit and save changes to a TiddlyWiki file that is on a local disk. If you put your TiddlyWiki file on your web site any changes made to it can't be saved.
(TODO, explain the "HideEditFeaturesOverHttp" or link to explanation)
(This can be a useful way to publish a web site. You can edit and save your site to your local TiddlyWiki file on your local disk. When it's finished simply upload the file for the rest of the world to see).
The above information applies to a standard, off-the-shelf TiddlyWiki. However, there ''are'' some ways you can get an editable/saveable TiddlyWiki via the web.
'' Options for making TiddlyWiki editable/saveable via the web ''
There are a [[Multi-User Collaboration|number]] of [[Server-Side_Implementations|server-sides]] that make it possible to save over HTTP.
Alternatively, a hosted service like [[Tiddlyspot]] can be used for convenience.

!Summary
The shadow tiddler ImportTiddlers provides access to importing tiddlers.
!Default Contents
{{{
<<importTiddlers>>
}}}
<<importTiddlers>>
!Description
The gradient macro renders a vertical or horizontal gradient as a background to content.
!Usage
{{{
<<gradient direction start-color mid-color end-color>>
INNER CONTENT
>>
}}}
{{annotation{
''Note'': Notice how the INNER CONTENT directly follows the gradient macro and is closed with another pair of greater-than characters {{{>>}}}.
}}}
Use the following parameters...
| !Parameter | !Description |
|''direction''|either {{{vert}}} (vertical) or {{{horiz}}} (horizontal)|
|''start-color''|the color at which the gradient starts|
|''mid-color''|the color at the middle of the gradient, not required|
|''end-color''|the color at which the gradient ends|
|''INNER CONTENT''|the wiki text rendered inside the gradient|
{{annotation{
''Note'': Using a mid-color is not required. It is enough to define a start- and an end-color for the gradient.
}}}

Every TiddlyWiki or [[TiddlySpace|Space]] provides a [[Backstage Area]] usualle in the top right corner providing management tools.
In TiddlyWiki, the default Backstage Area gives you...
* a button to [[save changes|saveChanges]]
* a [[SynchronizationWizard]]
* an [[ImportWizard|ImportTiddlers...]]
* [[AdvancedOptions|AdvancedOptions...]]
* an [[UpgradeWizard]]
* a [[PluginManager|PluginManager...]]
In TiddlySpace the [[Backstage Area]] allows you to...
*manage your user account
*create new spaces
*include other spaces or remove included spaces
*add new members or remove members
*perform various actions related to content tiddlers
One of the standard fields of a tiddler is called tags which allow you to categorize tiddlers. Tagging makes most sense if a tiddler has a tag of a more abstract category to which it belongs, i.e. ''Apple'' would have a tag of ''Fruit''.
Tags therefore are not just individual words, e.g. <<tag "Core Macros">>.
In TiddlyWiki, tags are first class members and as such themselves tiddlers. In this way, an elaborate tagging hierarchy can be defined.

There are numerous ways to stage your TiddlyWiki. You can, in fact, use it to create your own website.
!Hosting Services
Good places to work with TiddlyWiki online are...
;TiddlySpace
:» your number one place for TiddlyWiki based collaboration
;TiddlySpot
:» hosting TiddlyWiki made as simple as it gets
;TiddlyHoster
:» use the power of TiddlyWeb to manage tiddlers with bags, profiles and policies
;Web Hosting
:» Do you have a webserver or access to shared webhosting? Well, its actually quite simple using an [[FTP|http://en.wikipedia.org/wiki/File_Transfer_Protocol]] programm like [[FileZilla|http://filezilla-project.org]] to upload your TiddlyWiki and external files like images in some subfolder to your webspace.
!Cloud Storage
It is quite simple to stage your TiddlyWiki using [[Dropbox|SimpleDropboxPublishing]] or similar services, like Box.net, ~SkyDrive, etc...
!Email
That's right. If you're a singe-file purist in the TiddlyVerse you might as well just email a TiddlyWiki to someone and share all the information and dynamic features instantly. If you also use images in folders along with it, zip it up, and spread the word.

Custom macros are not part of the [[TiddlyWiki core|Core Macros]]. Instead they are written by user, or simply copied and reused from another site or repository.
Much of the power of TiddlyWiki <<version>> lies in the ease with which users can create macros and [[Plugins]] to customize their wikis, and share them with each other.
Information on how to write a custom macro can be found in @TiddlyWikiDev.

!Description
The [[view macro|view]] is a powerful macro that allows you to output the value of a tiddler field and format them.
!Usage
In general, the [[view macro|view]] is used in the shadow tiddler called ViewTemplate, e.g.:
{{{
<div class='viewer' macro='view text wikified'></div>
}}}
To use it in wiki text, use...
{{{
<<view field mode>>
}}}
The first parameter is the field which you want to output, e.g.:
* title
* text
* created
* modified
* ##sectionName
* ::sliceName
''Note:''
* The field {{{tags}}} cannot be used.
* If you use {{{##sectionName}}} or {{{::sliceName}}} with the wikified parameter, it's possible to produce endless loops. So ''be carefull''!
The second parameter defines the output mode in which the value of the field is rendered.
|!Mode|!Description|width:300px;!Example|
|link|renders the value as a link|{{{<<view title link>>}}}<br/>- <<view title link>>|
|text|renders the value exactly as stored|{{{<<view modified text>>}}}<br/>{{{<<view modified text>>}}}|
|date|outputs the field value as a date with an optional third parameter being the [[date format|DateFormats]], e.g. for the fields {{{created}}} or {{{modified}}}.|{{{<<view created date>>}}}<br /><<view created date>><br/>{{{<<view modified date "YYYY">>}}}<br><<view modified date "YYYY">>|
|wikified|outputs the field value as wikitext with an optional third parameter that can be used for formatting; {{{%0}}} corresponds to the field value. <br/><br/>''Note:'' the placeholder starts with {{{%}}} in contrast to a placeholder used by the [[tiddler macro|tiddler]] which start with {{{$}}} |{{{<<view "server.bag" wikified "//%0//">>}}}<br/><<view "server.bag" wikified "//%0//">>|
The [[space|Space]] created for a [[user|User]] when [[registering|Register]] with [[TiddlySpace]] is called the users' [[Home Space]].
A [[Home Space]] has the same name as the [[user|User]] and is used by the system to store user information, such as their [[avatar|SiteIcon]].
''Note:'' It is possible for a [[user|User]] to [[add another user as a member|Add Member]] to their [[Home Space]] which eventually also allows for a [[user|User]] to remove themselves or be removed from their own [[Home Space]].
In a standard TiddlyWiki, how a tiddler is displayed is determined by the shadow tiddler called ViewTemplate.
See [[Alternative Tiddler Layouts]] if you wonder [[How to display different layouts for diferent tiddlers?]]
@@Please do not modify this tiddler; it was created automatically upon space creation.@@

[[TiddlyWiki|http://tiddlywiki.com]] is a single-file wiki containing all the features of a [[wiki|http://en.wikipedia.org/wiki/WikiWikiWeb]] such as layout, styles, code and functionality for editing, saving, tagging and searching content.
In its basic form of a single html file it's highly portable -- so you can email it, put it on a web server or take it with you on a usb stick.
The following lists possible things to work on...
;[[Documentation Sources|DOC - Documentation Sources]]
:» lists topics that need to be analyzed for which content may need to be reviewed or created
;tiddlers tagged <<tag REVIEW>>
:» are tiddlers that may need improvements
;tiddlers tagged <<tag DELETE>>
:» have been flagged for deletion
;tiddlers tagged <<tag html>>
:» are used for the [[html representation|html]] of [[TiddlyWiki.org]]
;tiddlers tagged <<tag REDIRECTED>>
:» now point to a different tiddler; may later be resolved differently
;[[excludeLists]] / [[excludeSearch]]
:tiddlers hidden from default lists or search
;best practises
:» collect ideas for desirable structures and content of [[this wiki|Welcome]]@tiddlyspace
;missing contents?
:» referenced, yet not existing... <<tag excludeMissing>>
Extensions to the primitive {{{String}}} type in JavaScript...
<<list filter [startsWith[title,String.]][sort[title]]>>
The view mode refers to the mode of viewing a tiddler.
By default, how a tiddler is displayed is defined by one of the shadow tiddlers that control the layout of TiddlyWiki called [[ViewTemplate]].

!Summary
In a standard TiddlyWiki, the TabTags shadow tiddler outputs all tags of a TiddlyWiki using the [[allTags]] macro and is displayed as the {{button{Tags}}} tab in the right sidebar.
!Default Contents
{{{
<<allTags excludeLists>>
}}}
The ''getTags'' method that belongs to the ''store'' object is used to return a list of all the tags used in your tiddlywiki and the number of times each is used.
It takes one optional parameter, an array of all the tags you wish to exclude from the returned results.
You can use it without excluding some tags like so:
{{{
store.getTags();
}}}
This will return something like this:
{{{
[["command", 1], ["concept", 3], ["Developer Tools", 5], ["excludeLists", 74], ["excludeMissing", 7], ["excludePublisher", 1], ["excludeSearch", 72], ["global", 3], ["method", 17], ["store", 4], ["story", 4], ["systemConfig", 39], ["tiddler", 3], ["tiddlywiki api", 1]]
}}}
To filter out certain tags use it like this:
{{{
store.getTags(["excludeLists", "excludeSearch", "excludePublisher", "excludeMissing", "systemConfig"]);
}}}
This will return something like this:
{{{
[["command", 1], ["concept", 3], ["Developer Tools", 5], ["global", 3], ["method", 17], ["store", 4], ["story", 4], ["tiddler", 3], ["tiddlywiki api", 1]]
}}}
!Summary
This <<tag global>> function loops over all ancestors of a given root while running the refresh handler for those that have a [[refresh attribute defined|dom element refresh attribute]].
!Signature
{{{function refreshElements(root, changeList) {} }}}
!Returns
undefined
!Arguments
;1. root
:the DOM node of which all ancestors are inspected
;2. changeList
:a list of tiddler names that have changed<br>{{annotation{
''Warning:'' If changeList is not provided then all tiddlers will be refreshed which could trigger lots of unnecessary refreshes.

To enable editing of the Tiddlywikis in...
'' Internet Explorer ''
'''Have to add an image here'''
* In IE, choose Tools > Internet Options
* Go to the Security tab and select "Local Intranet" Zone
* Click Default Level (to clear the Custom Level settings)
* Set the Security level to Low
* Close all open browsers
* You can now edit the wiki
Also Try:
If TiddlyWiki has been downloaded using Internet Explorer on Windows XP with Service Pack 2 and stored on an NTFS-formatted drive, any attempts to save changes will usually fail with the following error message:
It's not possible to save changes. Possible reasons include:
- your browser doesn't support saving (Firefox, Internet Explorer, Safari and Opera all work if properly configured)
- the pathname to your TiddlyWiki file contains illegal characters
- the TiddlyWiki HTML file has been moved or renamed
The solution is to right-click on the TiddlyWiki HTML file and choose Properties. If the file is blocked, there will be an Unblock button on the resulting property sheet, which will remove the protection and allow the file to be saved.
'' Safari / Opera ''
The updated [[TiddlySaver|http://www.tiddlywiki.com/#TiddlySaver]] Java applet permits TiddlyWiki to save changes from Safari & Opera, eliminating the Java Policy step <br>
<br>
URL: http://www.tiddlywiki.com/#TiddlySaver <br>
Filename: TiddlySaver.jar <br>
File Type: Java applet <br>
Location: Saved in the same directory as the TiddlyWiki file <br>
Note: TiddlySaver.jar is signed by UnaMesa Association, their certificate is signed by Thawte Code Signing CA intermediate certificate & is chained to the Thawte Premium Server CA root certificate. The first time this applet runs, allow the browser to trust the certificate chain to be able to use the applet, even if the certificate is indicated as valid <br>
<br>
Note that there is no longer any need for a .java.policy file <br>
<br>
Ensure that if a backup directory is specified in AdvancedOptions, which does not exist, TiddlySaver will not run; due to a software bug <br>
<br>
Appreciation for the original TiddlySaver code: Andrew Gregory <br>
Appreciation for arranging the certificate magic: BidiX
'' Opera Portable Edition ''
... cannot save. It cannot use TiddlySaver.jar, because it does not support Java.
'' Opera on Ubuntu ''
If your version of Ubuntu doesn't currently have Java installed, when you try to save changes you will receive a message that reads like the following:
<localhost>
It's not possible to save changes. Possible reasons include:
- your browser doesn't support saving (Firefox, Internet Explorer, Safari and Opera all work if properly configured)
- the pathname to your TiddlyWiki file contains illegal characters
- the TiddlyWiki HTML file has been moved or renamed
To fix this:
#[[Download java|https://help.ubuntu.com/community/Java]].
#Then update Opera to use the new Java libraries. [[Source Instructions|http://ubuntuforums.org/showthread.php?t=69275]]
##First find the java library using "locate libjava.so".
##In Opera, enable Java, set the "Java Options" folder to the java library folder.
#Finally, reboot Opera.
When you next try to save changes, you will be greeted by a permissions dialog to allow saving. You should now be able to save your changes!

Open MainMenu for editing. Position the cursor where the item is to appear and type in the name of the tiddler. If the tiddler's name is a WikiWord it will work automatically as a link. If not, insert two square brackets either side of the tiddler name: <code><nowiki>[[tiddler name]]</nowiki></code>.
Close MainMenu. You should now see the new item displayed.

!Description
The saveChanges macro generates a button to save all changes to disk -- in a standard TiddlyWiki it is displayed in the SideBarOptions tiddler in the right sidebar.
!Parameters
{{{<<saveChanges [label] [tooltip]>>}}}
Introduced with TiddlyWiki v2.4, the optional parameters define the button's label and tooltip.
!Usage
{{{
<<saveChanges 'Save Now!' 'Click here to save this TiddlyWiki now!'>>
}}}
<<saveChanges 'Save Now!' 'Click here to save this TiddlyWiki now!'>>
The store is an instantiance of the [[TiddlyWiki.class]] and used to access, manipulate and create tiddlers.
> Your best bet is to upload them and maintain them on tiddlyspace.com
People use several approaches for distributing TiddlyWiki plugins:
- Publish at tiddlyspace
- Publish on github
- Publish on your own site (eg tiddlytools.com)
- Publish on [[tiddlyspot|http://www.tiddlyspot.com]]
TiddlyHub didn't really take off; it doesn't really achieve much more
than doing a Google search.
The most important thing is probably to announce your plugin in a
message to the group.
See [[Finding A Tiddler]]...
!Description
The [[option]] macro renders inputs for editing option cookies, e.g.
*checkboxes for boolean cookies
*input fields for text cookies
!Usage
{{{
UserName: <<option txtUserName>>
}}}
UserName: <<option txtUserName>>
{{{
<<option chkAutoSave>> Auto save changes?
}}}
<<option chkAutoSave>> Auto save changes?
I just started using this tonight and decided to save it. Got the above and did google searches and mess with my internet sites and all that crud.
Then I took a minute and thought, it's a .html file. Let's try saving it from File > Save As in IE and renaming it. So I did that and named it "test." I then opened test.html with "Open With" in IE from where I saved it and did a couple changes, then I saved it using the "save" feature in the "backstage" shortcut in the upper right. It saved this time. I went and looked in the folder where "test.html" was saved and it saved it how tiddlywiki claimed they name saved files: test.eightnumbers.morenumbers
I closed IE and then opened test.numbers.numbers and it opened and it had kept my changes.
My guess is that the "empty" file that they sent to get started with is not working correctly or maybe you just need to do this anyways.
Hope this helps someone.
!Summary
This prototype function of the [[Story]] class returns the DOM element id of the tiddler element.
!Signature
{{{Story.prototype.tiddlerId = function(title) {} }}}
!Returns
''string:'' the DOM element ID of the tiddler in the story column
!Arguments
;1. title
:the tiddler name
!Example
{{{
story.tiddlerId('getOrphans()');
}}}
''returns:'' 'tiddlergetOrphans()'
In TiddlySpace, the following bubble appears on every [[Tiddler]].
The number inside it represents the number of spaces that __you__ follow which have a tiddler that goes by the same name:
:[img[FollowingBubble.png]]
It is primarily used as a way to collaborate on a given subject.
!Summary
This function of the <<tag Tiddler "Tiddler Class">> returns an array of strings corresponding to [[TiddlyLinks|TiddlyLink]]@tiddlywiki present in the tiddler text. Use instead of accessing the links property directly.
!Signature
{{{Tiddler.prototype.getLinks = function() {} }}}
!Returns
array[string]: titles of all [[TiddlyLinks|TiddlyLink]]@tiddlywiki in a tiddler text
!Arguments
none
!Example
{{{
var tiddlerObj = store.getTiddler('Functions');
tiddlerObj.getLinks();
}}}
''returns:'' an array of all [[TiddlyLinks|TiddlyLink]]@tiddlywiki in the tiddler [[Functions]], e.g. {{{["TiddlyWiki Core"]}}}
''Deprecated'': Did output the same SynchronizationWizard as in the [[Backstage Area]].
!Description
The [[slider]] macro provides button that allows to toggle the visibility of [[transclusion|transcluded]] content of some tiddler in another tiddler.
!Usage
{{{
<<slider chkUniqueCookieName tiddler label tooltip>>
}}}
The following macro parameters are required...
| !Parameter | !Description |h
|''chkUniqueCookieName''|use the first parameter to define a unique cookie name starting with {{{chk}}} in which the toggle state is saved for this slider; the state is reapplied when the tiddler is reopened |
|''"""tiddler"""''|a reference to a tiddler-title, -section or slice to be content of the slider|
|''label''|the title for the slider button|
|''tooltip''|the tooltip for the slider button|
!Example:
{{{
<<slider
chkSliderGettingStarted
[[GettingStarted]]
"Getting Started"
"Show getting started info...">>
}}}
<<slider chkSliderGettingStarted [[GettingStarted]] "Getting Started" "Show getting started info...">>
!Using Hidden Sections In The Same Tiddler
If you want to have both the slider and the target content in the same tiddler, you can use [[hidden sections|http://tiddlywiki.org/#%5B%5BHidden%20Text%5D%5D]], e.g.
<<slider
chkHiddenStuff
"slider##HIDDEN"
Hidden!
"Click to show hidden stuff..."
>>
{{{
<<slider
chkHiddenStuff
"slider##HIDDEN"
"Hidden Stuff"
"Click to show hidden stuff..."
>>/%
!HIDDEN
hidden slider content

!Summary
In the shadow tiddlerSiteTitle you can define the title of your TiddlyWiki.
!Default Contents
{{{
TiddlyWiki
}}}
!TiddlySpace
In TiddlySpace the SiteTitle is by default set to the name of your newly created space.
!Summary
You can render text monospaced text, e.g. using the font //Courier//, while preserving line breaks and not applying WikiText formating or turning WikiWords into links.
!!"""Monospaced Text Block"""
<html><pre>
{{{
Some plain text including WikiLinks
}}}
</pre></html>''Displays as:'' a HTML <pre> element
{{{
Some plain text including WikiLinks
}}}
<<<
''Note:'' Code blocks are displayed using a white-space 'as-is', fixed-width font without no word-wrapping -- displayed in a box.
<<<
!!"""Monospaced Inline Text"""
Alternatively, you can also display monospaced text __inline__ by wrapping the text in three braces <html><code>{{{...}}}</code></html>:
<html><pre>{{{inline //code//}}}</pre></html>''Displays as:'' a HTML <code> element
{{{inline //code//}}}
<<<
''Note:'' Inline code uses a white-space 'collapsed', word-wrapped, fixed-width font.
<<<
!"""Monospaced Code Blocks"""
In order to display processed code as monospaced blocks in tiddlers, the wiki markup needs to be escaped using the respective language's comments syntax. While this is not necessary for a plugin to function properly, it makes the wikified tiddler contents generally look more appealing and readable from the TiddlyWiki UI.

!Summary
Use the [[store|TiddlyWiki.class]] function [[setTiddlerTag()|TiddlyWiki.prototype.setTiddlerTag()]] to set or remove a tag for a tiddler.
!Signature
{{{TiddlyWiki.prototype.setTiddlerTag = function(title,status,tag) {} }}}
!Returns
undefined
!Arguments
;1. (string) title
:» the tiddler title
;2. (boolean) status
:» true = set tag | false = remove tag
;3. (string) tag
:» the tag to be set
!Example
{{{
store.setTiddlerTag('SomeToDo',true,'#done');
}}}
''result:'' the tag {{{#done}}} is set for tiddler {{{SomeToDo}}}
Another example:
{{{
var toggleTagBasedOnFoo = function(tiddler, tag){
store.setTiddlerTag(tiddler, config.options.chkFoo, tag);
}
}}}
''result:'' sets a {{{tag}}} on a {{{tiddler }}} depending on the state of the checkbox option {{{chkFoo}}}.
!Best Practice
Each time {{{setTiddlerTag()}}} is called, it triggers a //notify// event for the changed tiddler, which causes re-rendering of any content depending on the changed tiddler.
Therefore, when programatically setting or removing a number of tags, temporarily block notification of changes in order to defer re-rendering until all tag changes are completed using:
{{{
store.suspendNotifications();
store.setTiddlerTag(...);
store.setTiddlerTag(...);
store.resumeNotifications();
store.notify("SomeTitle",true);
}}}
<<<
''Note:'' After calling {{{resumeNotifications()}}} invoke {{{store.notify("SomeTitle",true)}}} in order to re-render the current page display for affected tiddlers due to the changed tag values.

Plugins are a core feature of TiddlyWiki and...
* are optional modules extending the functionality of TiddlyWiki containing JavaScript
* are tagged <<tag systemConfig>> which TiddlyWiki interprets as "Please, run my code when the wiki loads!"
* typically provide macros or functions later triggered, e.g. by being calling from the tiddler text when a tidder is opened
* are mostly written by third-party developers and released under an open-source license
!"""Installing Plugins"""
[[Ideally|Plugin Installation]], to install a plugin, [[import|Importing]] it from its original location into your TiddlyWiki. You can, however, also copy and paste a plugin into a new tiddler.
{{annotation{
Note: In order to be processed on startup, plugins need to be tagged <<tag systemConfig>>.
}}}
!"""Executing Plugins"""
Plugins are loaded and run by TiddlyWiki upon startup in alpha-numeric, case-sensitive order by tiddler title, i.e. A-Z precedes a-z.
!!!Plugin Dependencies
Plugins support the use of a ''Requires'' [[slice]]. For a plugin which contains such a slice, the plugins listed as required are loaded first, regardless of the sort order of the titles.
Object detection can be used for [[strict dependency handling|Best Practices]].
!Example
If PluginA requires PluginB to be loaded first, it should contain the following directive:
{{{
|Requires|PluginB|
}}}
This will force an override of the normal load sequence and ensure that PluginB is loaded before PluginA is processed.

!Summary
The shadow tiddler GettingStarted by default contains information about how to start using TiddlyWiki and is referenced from your [[MainMenu|MainMenu__shadow]] and loaded on startup via [[DefaultTiddlers|DefaultTiddlers__shadow]].
!Customization
You can overwrite it with any contents you desire or change the tiddler [[DefaultTiddlers|DefaultTiddlers__shadow]] in order to define other tiddlers for startup.
!Considerations
A good use for it is to explain what your TiddlyWiki is about, especially when you plan on redistributing it or showcase your own [[plugins|Plugin]] and [[macros|Macro]].
!Summary

!Signature
{{{
Story.prototype.displayTiddler =
function(srcElement, tiddler, template, animate, unused, customFields, toggle, animationSrc)
}}}
!Returns
DOM reference: the opened tiddler

Click the "new tiddler" button towards the top right of the screen to write something in your space. You'll need to give it a title, some content and, optionally, some tags that will help you identify it later.
!Stuck for ideas?
Not sure what to write about? Not sure what to keep in your space? Other people use ~TiddlySpace for almost anything. How about some of the following:
* [[Save interesting sites|http://bookmarks.tiddlyspace.com]], images or articles from around the web so that you can refer back to them.
* [[Record your family tree|http://familytree.tiddlyspace.com]], store notes on long lost relatives or ancestors and map their relationship to you.
* [[Make up a pocketbook|http://pocketbook.tiddlyspace.com]] to store some useful information in, then print it out, [[fold it up|http://www.pocketmod.com/]], and take it with you.
* [[Plan your holiday|http://the-web-is-your-oyster.tiddlyspace.com/]], record where you're planning to go, note down places of interest and refer back to it later.
* [[Create a mindmap|http://mindmaps.tiddlyspace.com/]] to visualise your inner thoughts and see how they relate to each other.
* [[Set up a questionnaire|http://questionnaire.tiddlyspace.com/]] and get all your friends to answer it.
If you don't like any of those ideas, you can still use this space directly to keep notes and link them together, make a todo list and keep track of everything you're doing, or any one of a hundred million other things.
Still stuck? Check out the @featured space for more suggestions.

TiddlyFox is an extension for Mozilla Firefox created by [[Jeremy Ruston]] which enables TiddlyWiki documents loaded from a file:/// URI to save changes in a TiddlyWiki back to the local filesystem.
!Installation
Download and install the latest revision of TiddlyFox by clicking on the following link while in Firefox:
https://github.com/TiddlyWiki/TiddlyFox/blob/master/tiddlyfox.xpi
You can also install TiddlyFox form Mozilla's official addon library. However, this version typically lags behind the latest release:
https://addons.mozilla.org/en-US/firefox/addon/tiddlyfox
Surprisingly, you can also install TiddlyFox on the mobile version of Firefox for Android. Mozilla has done a good job to let a Firefox add-on to support both desktop and mobile platforms with just one .xpi.
!Background
Due to security issues, Firefox15 and above no longer support the use of the *privileged* file I/O functions needed by TiddlyWiki to save a local file. As a result, attempting to save from Firefox 15+ will produce the error you saw. Tiddlyfox restores the file I/O support for TiddlyWiki.
!Working with TiddlyFox
Whenever you open a TiddlyWiki document with TiddlyFox installed, you will be asked to confirm whether or not file saving should be permitted (OK/Cancel). Pressing OK allows TiddlyFox to provide file I/ O for the current document. TiddlyFox remembers that choice and applies it each time that document is opened, so that you only see the confirmation message the first time. Pressing Cancel bypasses the TiddlyFox addon and loads the document without support for file I/O (and thus, no saving of changes). If you press Cancel, TiddlyFox will ask for confirmation again the next time you open the document.

<<tiddler [[Comment Formatting]]>>
The //createTiddler// method of the Story.class opens a tiddler on the page. If a tiddler by the requested name doesn't exist, it appears ready to edit. This method takes four parameters:
* the overall parent DOM element to display the tiddler inside.
* the DOM element inside the first parameter to display directly after. A null value places it at the end of the entire element.

TiddlyWiki bookmarklets are small chunks of JavaScript that you can save as bookmarks in your browser.
When you open a bookmarklet in the context of an open TiddlyWiki, it acts as a plugin run by the browser without being stored in TiddlyWiki itself. This can be very convenient, as you can use a bookmarklet on any TiddlyWiki without a need to install a plugin in each one.
!"""Saving A Bookmarklet"""
To save a bookmarklet, simply add it to the Favourites or Bookmarks in your browser. To keep things tidy, add them to a dedicated folder for TiddlyWiki bookmarklets.
!"""Bookmarklet Sources"""

The ToolbarCommands shadow tiddler allows you to configure the [[commands|ToolbarCommands...]] by default displayed in a toolbar in the upper right area of a tiddler allowing you to inspect and interact with a tiddler.
<<<
[[ToolbarCommands]]
<<tiddler ToolbarCommands>>
<<<
Both the TiddlyWiki and the TiddlySpace core provide a number of commands, others are provided by plugins.
!Command Prefixes
A toolbar command can have the following prefixes...
|!Prefix|!Description|h
| {{{-}}} |invoked when the ESC key is pressed whilst in a text input field;<br>by default used to cancel the editing of a tiddler in EditMode|
| {{{+}}} |it will be invoked when you double-click on a tiddler;<br>by default used with the editTiddler command in ViewMode to trigger EditMode|
If you don't want to use either functionality, remove the prefixes and use the toolbar commands normally.
<<<
''Caution:''
When using these prefixes, make sure you fully understand what will happen, e.g. putting {{{+}}} before the {{{deleteTiddler}}} command will delete a tiddler every time you double click on it
<<<
!Expanding and Collapsing
The toolbar can be partially collapsed. Use the separators {{{<}}} and {{{>}}} to specify where exactly the {{button{more »}}} and {{button{« less}}} buttons will be rendered in order to expand and collapse the toolbar into its full state.
<<<
In TiddlySpace, instead of expanding and collapsing the toolbar a button is used providing you with a popup of those commands that are by default hidden.
<<<
!Command Reference
The following provides a list of toolbar commands made available by the TiddlyWiki or TiddlySpace core or certain plugins...

!Interactive Delete
Open the tiddler for editing, then click the delete command in te toolbar at the top right of a tiddler.
!~TrashPlugin
Consider installing [[TrashPlugin|http://ido-xp.tiddlyspot.com/#TrashPlugin]] by [[Ido Magal|TrashPlugin|http://ido-xp.tiddlyspot.com/#TrashPlugin]] which allow to undo a deletion. Empty the trash regularly since you cannot reuse a tiddler name before it's finally deleted.
!Deleting Tiddler That Is Tag
Consider installing [[RenameTagsPlugin|http://mptw.tiddlyspot.com/#RenameTagsPlugin]] from [[Simon Baird|http://monkeygtd.blogspot.com]]. It will prompt you whether or no you will also "Remove tag from N tiddlers?".
!Batch Delete
Deleting multiple tiddlers can be greatly simplified using either [[TiddlerTweakerPlugin|http://www.TiddlyTools.com/#TiddlerTweakerPlugin]] or [[ExportTiddlersPlugin|http://www.TiddlyTools.com/#ExportTiddlersPlugin]] by [[Eric Shulman|http://www.TiddlyTools.com]] or the [[Bookmarklet]] [[DelleteAllTagged]], a small piece of JavaScript code, that can be saved and run as a bookmark.

!Description
The following [[script|Scripts]] allows to convert lists to WikiLinks.
!Code
{{{
<script label="L2W" title="convert list to wikilinks">
var here=story.findContainingTiddler(place);
if (!here) return;
var title=here.getAttribute("tiddler");
var tid=store.getTiddler(title);
var t=store.getTiddlerText(tiddler.title) ;
var target = store.getTiddler(tiddler.title) ;
var txt='[['+tid.text.split('\n').join(']]\n[[')+']]';
store.saveTiddler
(tid.title,tid.title,txt,tid.modifier,tid.modified,tid.tags,tid.fields);
</script>
}}}
!Instructions
Paste a line-seperated list into a tiddler then "run" the script on the list to get double bracketed list items.

You can center an element horizontally by wrapping it in a class while applying the css {{{margin: 0 auto}}}.
!Example
The following illustrates two ways for centering tables...

ControlView is the mechanism which TiddlySpace employs to prevent the serving of content from other [[spaces|Space]] which would otherwise be available via [[recipes|Recipe]] and [[bags|Bag]] sharing the same TiddlyWeb instance.
Without ControlView, it would be possible to construct a URI to serve content from {{{evilspace}}} which //appeared// to belong to the {{{goodspace}}} domain, e.g.:

Versions of TiddlyWiki before and including 2.6.3 are known to have an issue with the upgrade function. To upgrade these versions you will need to download an empty latest version of TiddlyWiki and import your content into it using the "import" function in the backstage.
# Download http://www.tiddlywiki.com/empty.zip (the latest TiddlyWiki version is in there).
# Make a copy of empty.html and either place it in the same directory as the TiddlyWiki you want to upgrade or give it the same name of the TiddlyWiki you want to upgrade and place it in a different directory.
# Load your new empty latest version of TiddlyWiki.
# Go to the backstage area and select import.
# Select the TiddlyWiki you want to have upgraded.
# Import everything from the old TiddlyWiki into this new latest version of TiddlyWiki.
# Save your changed TiddlyWiki and reload it.
# Should work.
This is inverse of the normal way of upgrading: instead of upgrading the core of your TiddlyWiki you are adding all the non-core content of your current TiddlyWiki into a new latest core of TiddlyWiki.
Once you have upgraded your TiddlyWiki to version 2.6.4 or later you will be able to upgrade to subsequent versions in the normal manner.

!END%/
! Code Structure
{{annotation{The samples provided here are merely suggestions, not strictly-enforced regulations.}}}
!! Namespacing
Plugins' functions should be registered in the {{{config.extensions}}} namespace (built in from v2.5):
{{{
config.extensions.SamplePlugin = {
sampleFunction: function() {
/* ... */
}
};
}}}
Similarly, functions specific to a certain macro or toolbar should be attached to the {{{config.macros}}} or {{{config.commands}}} object, respectively:
{{{
config.macros.SampleMacro = {
handler: function(place, macroName, params, wikifier, paramString, tiddler) {
/* ... */
}
};
config.commands.sampleCommand = {
handler: function(event, src, title) {
/* ... */
}
};
}}}
Overview of common TiddlyWiki namespaces:
* {{{config.extensions}}}: [[DevPlugins]]
* {{{config.macros}}}: [[DevMacros]]
* {{{config.commands}}}: [[DevToolbarCommands]]
* {{{config.paramifiers}}}: [[DevParamifiers]]
* {{{config.formatters}}}: [[DevFormatters]]
* {{{config.adaptors}}}: [[DevAdaptors]]
!! Documentation
Well-structured code simplifies readability and maintainability. Commenting is an important part of structuring code.
There are two basic levels of comments:
* block comments ({{{/* [...] */}}})
* inline comments ({{{// [...]}}})
This distinction can be used to create a semantic and visual distinction between headers and annotations:
{{{
/*
** [section]
*/
// [function description]
function foo() {
// [procedure description]
var foo = bar; // [explanatory comment]
}
/* [sub-section] */
function bar() {
var foo = bar;
}
}}}
{{annotation{While CSS only provides syntax for block comments, the same principle can be applied to [[StyleSheets]].}}}
!Extending Core Functionality
Instead of ''overwriting'' core functions, [[hijacking|DevHijacking]] should be used whenever possible to add the desired functionality either before or after invoking the hijacked code (via the {{{apply(this,arguments);}}} method). This allows other plugins relying on these functions to continue to operate.
However, hijacking the function is not always possible, given the nature of the specific core function or the desired changes. In that case, it is important to clearly note in the respective plugin's documentation that installing the plugin may have adverse affects on other plugins installed in the same document.
! Declaring Global Functions
Function statements should be avoided within plugins. Function statements are of the form:
{{{
function foo() {
// ...
}
}}}
Because plugins' code is processed using {{{eval()}}}, certain browsers (e.g. IE7 and Safari 3) leave the function in {{{eval()}}}'s local scope.
The way around this is to use expressions to declare such functions as variables, ideally adding an explicit {{{window}}} prefix:
{{{
window.foo = function() {
// ...
}
}}}
This is especially relevant when overriding core functions that are declared using function statements, such as {{{displayMessage()}}}, event handlers, etc.
!Dependency Handling
While TiddlyWiki recognizes a ''Requires'' slice in plugins, this is only used to determine plugins' loading order and will not result in an error if the respective dependencies are not found in the document.
Strict dependency checking has to be implemented by the respective plugin itself. However, rather than checking for the respective plugin's name, object detection should be employed for maximum flexibility:
{{{
if(!window.foo) { //# "window" only required to prevent ReferenceError if "foo" is a global variable
throw "Missing dependency: Foo";
}
}}}
({{{foo}}} might be a property of TiddlyWiki's ''config'' namespace, e.g {{{config.extensions.SamplePlugin}}}
{{annotation{The {{{pluginInfo.log}}} array can be extended to add a message without stopping execution of the plugin:}}}
{{{
pluginInfo.log.push("lorem ipsum");
}}}
!Creating Aliases
Sometimes variable names can become very long - especially when using namespaces.
A closure (anonymous wrapper function) can be used to create a local scope in which local variables can be used as [[aliases|http://docs.jquery.com/Plugins/Authoring#Custom_Alias]], essentially providing "shortcuts" for accessing variables from the parent scope:
{{{
(function($) { //# set up local scope and jQuery alias
var plugin; //# alias
plugin = config.extensions.SamplePlugin = {
sampleMessage: "lorem ipsum",
sampleFunction: function() {
/* ... */
}
};
displayMessage(plugin.sampleMessage);
plugin.sampleFunction();
})(jQuery); //# end of local scope, passing in jQuery object

From the [[Glossary|Evaluated Parameter]]...
<<<
<<tiddler "Evaluated Parameter">>
<<<
To achieve this, use double braces{{{ {{code}} }}}to enclose the desired and tested JavaScript code -- the calcualted return value is then pass down to your macro, e.g.: {{{<<someMacro {{code}}>>}}}
!Example
For example, {{{<<tiddler {{ document.location.href }}>>}}} will try to display a tiddler by the same name as the address displayed in your browser address bar, i.e. {{{document.location.href}}} is evaluated via javascript and the result then passed down to the respective macro, in this case the [[tiddler macro|tiddler]].
![[Transclusion]]
Using the [[tiddler macro|tiddler]] with evaluated parameters is a form of [[parametric transclusion|Transclusion]].
!TiddlySpace
Due to security concerns, evaluated parameters are by default disabled on TiddlySpace.
{{alert{Caution!}}} To enable them nontheless, put this into a zzConfig tiddler tagged <<tag systemConfig>> and parameter evaluation for macros — especially the tiddler macro — will be reenabled:
{{{
config.evaluateMacroParameters = "full";
}}}
!Summary
In a standard TiddlyWiki, the MarkupPreHead shadow tiddler contains HTML and is inserted at the beginning of the {{{<head>}}} section of the TiddlyWiki HTML.
!Default Contents
<!--{{{-->
<link rel='alternate' type='application/rss+xml' title='RSS' href='index.xml' />
<!--}}}-->
!Use Cases
tbd
WikiText is a markup language that defines special text markup that must be used in order to produce a desired output, e.g. {{{__underline__}}} eventually being displayed as __underline__. TiddlyWiki uses its own [[TiddlyWiki Markup]] for [[formatting text|Formatting Text]].
For examples see...
<<list filter [tag[Formatting]]>>
!!Also see
;@WikiText
:a dedicated space for explaining [[TiddlyWiki Markup]]
Use the [[version macro|version]]:
{{{<<version>>}}}
<<version>>
!Feeling Adventurous?
You can also open the source code of your TiddlyWiki. Near the top is a section that looks like this:
>{{{major: 2, minor: 2, revision: 6, date: new Date("Oct 18, 2007")}}}
In this case, the version is {{{2.2.6}}}.
/***
|''Name''|TiddlySpaceTiddlerIconsPlugin|
|''Version''|0.8.10|
|''Status''|@@beta@@|
|''Author''|Jon Robson|
|''Description''|Provides ability to render SiteIcons and icons that correspond to the home location of given tiddlers|
|''Source''|http://github.com/TiddlySpace/tiddlyspace/raw/master/src/plugins/TiddlySpaceTiddlerIconsPlugin.js|
|''Requires''|TiddlySpaceConfig BinaryTiddlersPlugin ImageMacroPlugin TiddlySpacePublishingCommands|
!Notes
{{{<<tiddlerOrigin>>}}} shows the origin of the tiddler it is being run on.
In TiddlySpace terms this means it will determine whether the tiddler is external, public or private.
Where private it will analyse whether a public version exists and distinguish between the different scenarios.
If a tiddler is external, the SiteIcon of that external space will be shown
!Parameters
width / height : define a width or height of the outputted icon
label: if label parameter is set to yes, a label will accompany the icon.

|''Version''|0.6.1|
|''Author''|Jon Robson|

!Usage
{{{<<groupBy tags>>}}}
mimics allTags macro
{{{<<groupBy server.bag>>}}}
groups by the server.bag field (this version contains TiddlySpace specific code for turning a bag into a space name)
{{{groupBy modified dateFormat:"YYYY"}}}
group tiddlers by year.
{{{<<groupBy tags exclude:excludeLists exclude:systemConfig>>}}}
group tiddlers by tag but exclude the tags with values excludeLists and systemConfig
Within that group you can also exclude things by filter
{{{groupBy modifier filter:[tag[film]]}}}
will group tiddlers tagged with film by modifier.

The ''saveTiddler'' method of a [[store object|TiddlyWiki.class]] is typically called in response to the author clicking the '''done''' link after editing a tiddler.
This method takes six parameters:
* the old title of the tiddler
* the new title of the tiddler
* the tiddler's source code
* the name of the author
* the modification date
* the tags (as an array of strings).
This feeds directly into [[Tiddler]]'s [[set]] method, and does not save changes to the document on disk.
Extensions to the primitive {{{Array}}} type in JavaScript...
<<list filter [startsWith[title,Array.]][sort[title]]>>
!Summary
This <<tag global>> function renders an internal link to a tiddler.
!Signature
{{{createTiddlyLink(place, title, includeText, className, isStatic, linkedFromTiddler, noToggle) {} }}}
!Returns
DOM reference: to the created link
!Arguments
;1. (DOM reference) place
:where the link will be placed
;2. (string) title
:the tiddler title
;3. (string) includeText
:(optional) the pretty title to be show
;4. (string) className
:(optional) the css class name applied to the link
;5. (boolean) isStatic
:(optional) ?!?
;6. (string) linkedFromTiddler
:(optional) ?!?
;7. (boolean) noToggle
:(optional) ?!?
!Example
{{{
createTiddlyLink(place,'Foo');
}}}
''outputs:'' an internal link to tiddler 'Foo'
Using a standard TiddlyWiki the shadow tiddler ViewTemplate defines how an individual tiddler is displayed. You are not able to use alternative layouts for different tiddlers. All will show a title, some subtitle, a toolbar, etc... depending on how your ViewTemplate is set up.
To display different layouts for diferent tiddlers, you can use third-party plugins.
!"""TaggedTemplateTweak"""
[[TaggedTemplateTweak|http://www.TiddlyTools.com/#TaggedTemplateTweak]] by [[Eric Shulman / TiddlyTools|http://www.TiddlyTools.com]] allows you to create alternative templates, e.g. an ''"""AlternativeViewTemplate"""''.
If you then tag a tiddlers with "Alternative" (or even "alternative") the ''"""AlternativeViewTemplate"""'' will be used to display the tiddler instead of the ViewTemplate.
The same mechanism can also be used to create an alternative EditTemplate, e.g., e.g. ''"""AlternativeEditTemplate"""''.

* Updates shadow tiddlers to known TiddlySpace shadow tiddlers
* adds the following filters
{{{
[is[tiddler]] - allows you to match all tiddlers - useful for applying the isnot filter (see later)
[is[image]] - returns only image tiddlers (e.g. png, jpeg, gif etc..)
[is[shadow]] - returns if the tiddler is a known shadow tiddler
[is[svg]] - returns only svg tiddlers
[is[tagged]] - returns tiddlers with tags
[isnot[image]] - filters result of previous filters for ones that are not images
[notag[<tag>]] - filters result of previous filters for ones without a tag
[nofield[<field>]] - check for absence of field or field value in previous filters
[has[<field or attribute>]] - match tiddlers which have a field or attribute set.
[and[<filter expression>]] - e.g.[and[tag:foo]] checks all tiddlers from previous filters for a tag foo.
[nobag[foo]] - removes any tiddlers previously returned by a previous filter that belong to the given bag
[is[open]]
[startsWith[title,Foo]] returns all tiddlers who's titles start with Foo.

A [[TiddlySpace|Space]] comprises of two collections of [[tiddlers|Tiddler]]: a [[public|Public]] [[bag|Bag]] and a [[private|Private]] [[bag|Bag]].
Tiddlers in the public bag are visible to anyone who has access to the TiddlySpace server, in the case of [[tiddlyspace.com|http://tiddlyspace.com]] this is anyone on the Web.
Only a [[member|Member]] of the [[space|Space]] may alter a public tiddler.
{{annotation{
''Note:'' This default may be changed to more fine grained access control settings by a [[member|Member]] of a space using the TiddlyWeb [[HTTP API]].

!Description
The [[tiddler macro|tiddler]] allows you to embed (or [[transclude|Transclusion]]) the entire text, a section or a slice of some tiddler into the current tiddler.
!Usage
{{{
<<tiddler [TextReference]>>
}}}
The {{{TextReference}}} can be any of...
| !Reference | !Example |h
|a tiddler title |{{{<<tiddler SomeTiddler>>}}}|
|a tiddler section|{{{<<tiddler [[Some Tiddler##Some Section]]>>}}}|
|a tiddler slice|{{{<<tiddler "Some Tiddler::SliceName">>}}}|
{{annotation{
''Note:'' Notice the different ways for wrapping a macro parameter in quotes or double square-brackets.
}}}
!"""Parameterised Transclusion"""
You can create tiddlers as templates by using the placeholders {{{$1}}} to {{{$9}}} for the content that you want replaced during transclusion.
{{annotation{
''Note:'' Transclusion parameters start with a dollar sign ({{{$}}}) not with percent ({{{%}}}) as commonly used in JavaScript string functions.
}}}
Appending the {{{with:}}} parameter followed by the desired parameter values will replace the placeholders {{{$1}}} to {{{$9}}} with these values in the transcluded tiddler content.
!!!"""An Example For Parameterized Transclusion"""
Create a tiddler called MyTemplates containing this text:
<<<
{{{!What I like}}}
{{{I like //$1// in [[$2|https://www.google.com/search?q=$2]]!}}}
<<<
Use transclusion while passing down parameters {{{$1='pineapple'}}} and {{{$2='Piña Colada'}}} as follows:
{{{
<<tiddler [[MyTemplates##What I like]] with: "pineapple" "Piña Colada">>
}}}
''The Output:''
<<<
I like //pineapple// in [[Piña Colada|https://www.google.com/search?q=Piña Colada]]!
<<<
!Description
The [[upgrade]] macro outputs the same UpgradeWizard as in the Backstage Area...
!Usage
{{{
<<upgrade>>
}}}
<<upgrade>>
Prevent a WikiWord from automatically becoming a link by putting a tilde (~) in front of it, e.g.:
{{{
~FooBar
}}}
~FooBar
!"""Using DisableWikiLinksPlugin"""
The [[DisableWikiLinksPlugin|http://www.tiddlytools.com/#DisableWikiLinksPlugin]] gives several options to customize automatic WikiWord linking, such as disabling it completely or only for tiddlers which don't already exist. After importing the plugin, these options must be enabled manually in the DisableWikiLinksPlugin tiddler; it may also be necessary to close and re-open the TiddlyWiki browser page before using the plugin for the first time.
All options are off by default, so settings applied by one user/in one browser will not be active for others. If you want to ensure that your options are in effect for, say, Web viewers, you can create a tiddler, e.g. DisableWikiLinksDefault, with a [[systemConfig]] tag and content like this:
{{{
config.options.chkDisableWikiLinks=false;
config.options.chkAllowLinksFromShadowTiddlers=false;
config.options.chkDisableNonExistingWikiLinks=false;
config.options.txtDisableWikiLinksList="DisableWikiLinksList";
config.options.txtDisableWikiLinksTag="excludeWikiWords";
}}}
Set the values to the defaults you prefer (e.g. change "false" to "true").

[[Category:FAQ]]
[[Category:Using TiddlyWiki]]
Here we are -- on TiddlySpace -- more precisely, the @TiddlyWikiDev space.
!"""What is TiddlySpace?"""
=> http://tiddlyspace.com
To set the default text alignment for all tiddlers, put something like this into your [[StyleSheet tiddler]]:
.viewer {
text-align: justify;
}
that CSS rule will fully justify your tiddler text.
TiddlyWiki provides a number of settings that allow you to configure your user experience.
In a classic TiddlyWiki these can be found in the right sidebar in the [[OptionsPanel]] from which also points to the [[AdvancedOptions]] that are as well accessible in the [[Backstage Area]] under ''Tweaks''.
@@Please do not modify this tiddler; it was created automatically upon space creation.@@
!Summary
Find the index for an element in the elements of an array for which a given field has a certain value.
!Signature
{{{Array.prototype.findByField = function(field,value) {} }}}
!Returns
integer: the index of the element where field matches value
!Arguments
;1. field
:the field to find the index for
;2. value
:the value to match against the elements field
!Example
{{{
var ti = 'Some Tiddler',
tids = store.getTiddlers();
tids.findByField("title",ti);
}}}
''returns:'' {{{true}}} when there is a tiddler with s title of {{{Some Tiddler}}}

A ''zzConfig'' or ''zzTweaks'', etc. is in fact a small plugin tiddler tagged <<tag systemConfig>> that you create to override ~TiddlyWiki defaults. It owes its name to the fact that plugins are loaded in alphabetical order, so zzSomething takes care of having it load last.
For details see [[Changing Default Options]].

For a basic description for tiddlers, see [[Tiddler Properties]]<<slider chkTiddlerProperties "Tiddler Properties" "»" "click to reveal tiddler properties">> and [[Tiddler]].
The [[Tiddler]] class represents a single tiddler. Instances of this class are created as the user creates tiddlers; they are not deleted if a user closes the corresponding tiddler in the story.
Changing an instantiated tiddler object does not affect the tiddler as saved by the author; to make changes to the tiddler that will be saved the next time the [[TiddlyWiki|TiddlyWiki.class]] is saved, call ''store.saveTiddler''.
!"""Tiddler Functions"""
<<list filter [startsWith[title,Tiddler.]][sort[title]]>>
!! Methods (docs need update)
* [[autoLinkWikiWords|Tiddler.prototype.autoLinkWikiWords]]: returns whether the tiddler should have WikiWords linked.
* [[changed|Tiddler.prototype.changed]]: a hook to be called after the Tiddler object has been modified.
* [[escapeLineBreaks|Tiddler.prototype.escapeLineBreaks]] and [[unescapeLineBreaks|Tiddler.unescapeLineBreaks]]: converts line breaks from textual and HTML representations.
* [[generateFingerprint|Tiddler.prototype.generateFingerprint]]: return a SHA-1 hash of the tiddler's text.
* [[getSubtitle|Tiddler.prototype.getSubtitle]]: returns a subtitle with author name and modification date.
* [[isTagged|Tiddler.prototype.isTagged]]: returns whether the tiddler has been assigned a specific tag.
* [[isReadOnly|Tiddler.prototype.isReadOnly]]: returns whether the tiddler can be edited.
* [[Tiddler.LoadFromDiv|Tiddler.prototype.loadFromDiv]]: instantiate a Tiddler from HTML.
* [[saveToDiv|Tiddler.prototype.saveToDiv]]: render HTML for storing the tiddler.
!! Modifying Tiddler Contents
Assigning contents directly to the ''tiddler.text'' property of a retrieved tiddler object *can* be tricky ([[link|http://groups.google.com/group/TiddlyWiki/browse_thread/thread/44edde8c58e99892]]).
Normally, the TW core functions, {{{store.saveTiddler()}}} or {{{tiddler.set()}}} (for low-level internal operations) are used to change the value in the tiddler data, and these functions trigger furtherprocessing, such as refreshing the display or even auto-saving the file in response to changes in tiddler content.
In addition, many plugins hijack these functions in order to add system-level extensions that are triggered whenever a tiddler is changed. Directly setting the value of {{{tiddler.text}}} completely bypasses these functions, preventing all add-on ''and'' core side-effects behaviors from being triggered.
!!How TiddlyWiki Stores Tiddlers
TiddlyWiki's saves each tiddler in the hidden store area in the following format:
{{{
<div title="tiddler title" modifier="author/editor" modified="YYYY0MM0DD0hh0mm" created="YYYY0MM0DD0hh0mm" tags="foo [[bar baz]]">
<pre>
Body of the tiddler
</pre>
</div>
}}}

Discussion around TiddlyWiki's core functions from a developers perspective.
You can bundle CSS in a plugin using the following mechanism taking advantage of [[Section Transclusion]]
To do this in your plugin, first include a section in a comment like so...
{{{
/*
!CSS
body { border: solid 1px black; }
!END*/
}}}
Be sure touse the {{{!END}}} heading to signal the end of the ''CSS'' section and thus the StyleSheet. Then include the following lines in your plugin code...
{{{
var name = "StyleSheet" + tiddler.title;
config.shadowTiddlers[name] = "/*{{{*/\n%0\n/*}}}*/".
format(store.getTiddlerText(tiddler.title + "##CSS"));
store.addNotification(name, refreshStyles);
}}}
This accesses the ''CSS'' section of the plugin tiddler and creates and registers a StyleSheet shadow tiddler for it, e.g. for a plugin tiddler called ''~FooPlugin'', the StyleSheet would be called ''~StyleSheetFooPlugin''.
!Summary
The shadow tiddler StyleSheet is intended for you to customise the look and feel of your TiddlyWiki using CSS such as...
{{{
.mainMenu {
color: red;
}
}}}
!Default Contents
''none''
!TiddlySpace
The default StyleSheet tiddler in TiddlySpace demonstrates how you can reference other StyleSheets tiddler the contents of which are then included in full ~, like that seen in TiddlySpace in the StyleSheetTiddlySpace
{{{
/*{{{*/
[[StyleSheetTiddlySpace]]
/*}}}*/
}}}
The [[TiddlySpace API]] is built on top of the TiddlyWeb HTTP API, which is described in the [[tiddlyweb documentation|http://tiddlyweb.peermore.com/wiki/#%5B%5BHTTP%20API%5D%5D]]. For example, you can [[click here|/tiddlers?select=tag:!excludeLists]] for a list of all tiddlers in this [[TiddlyWiki.org]] in their html representation.

There are numerous ways to get TiddlyWiki to display the way you want it to.
!"""Themes Repository"""
A few themes have been listed over time in the themes repository which provide empty [[TiddlyWikis|TiddlyWiki]] for you to start with...
http://themes.tiddlywiki.com
!"""How Themes Work"""
A TiddlyWiki theme basically is a set of [[shadow tiddlers|ShadowTiddler]] and [[style sheets|StyleSheets]], predefined tiddlers which may be bundled to a theme tiddler.
!Summary
The shadow tiddler AdvancedOptions provides access to several advanced options and accessible via the OptionsPanel in the [[Sidebar]] or the {{button{tweaks}}} command in the [[Backstage Area]] -- also see [[options macro|options]].
!Default Contents
{{{
<<options>>
}}}
<<options>>
You can use Javascript to dynamically calculate the value of a parameter which you actually want to pass down to a macro. This is called an evaluated parameter.
Extended HTML syntax is used in the [[Shadow Tiddlers|http://shadowtiddlers.tiddlyspace.com]] that define the structure and layout of a TW. The main shadow tiddlers are PageTemplate, EditTemplate, ViewTemplate.
It allows users to use TW macros and plugins within their TW document and not just in their tiddlers. An example from the ViewTemplate would be:
{{{
<div class='title' macro='view title text'></div>
}}}
More generically:
{{{
<... macro='macroName param param' ..>>
}}}
When encountered it is often interpreted by the [[wikify()]] method. When [[wikify()]] recognizes the embedded macro syntax, it calls on [[invokeMacro()]], which automatically sets a ''global'' window.tiddler variable to point to the current tiddler object that is being rendered. This enables the macro's parameter processing to use "evaluated parameters" that reference values within that tiddler object, like this:
{{{
<... someMacro ... {{tiddler.title}} ...>
}}}
@@Note: prior to TW2.4.3, you needed TiddlyTools' CoreTweaks #444, which added the global window.tiddler (and window.place) variables to the invokeMacro() function. Starting with TW2.4.3, this functionality was added to the core.@@
@@Note: for security reasons evaluated parameters were turned off in TiddlySpace@@
If and when the calculation and substitution of evaluated parameters is complete, invokeMacro then passes the parameter values onward for further rendering by the appropriate [[macro handler function|Macro Handler]]:
{{{
config.macros.someMacro.handler(place,tiddler,params,wikifier,paramString,tiddler)
}}}
For example in the view title example this would be:
{{{
config.macros.view.handler(place,tiddler,params,wikifier,paramString,tiddler)
}}}
Note: Typically, the tiddler parameter passed to the macro handler function is the same as the 'current tiddler' that is being rendered. However, when you use the "<<tiddler TiddlerName>>" macro to [[transclude]] content from other tiddlers, the //tiddler// param that is passed to any macros ''within the transcluded tiddler'' will reference that transcluded tiddler, rather than the outer //current// tiddler that is being rendered.
TiddlySpace keeps a revision history on all edits.
It is accessible by...
*clicking on the tiddler subtitle which contains the modified date
*using the ''revisions'' command under ''Show Additional Commands'' in the tiddler toolbar

TiddlyWiki's architecture for interacting with servers allows it to be plugged into a wide variety of servers. This is done through the addition of plugins containing custom server adaptors. Server adaptors are designed to allow things like importing tiddlers, loading missing tiddlers on the fly and synchronising changes with a server. Separate macros and core extensions implement such features by accessing the facilities provided by server adaptors.
Server adaptors are designed to use a familiar model akin to a device driver, adapting a standardised interface to whatever is required by the underlying server: [[WebDAV|http://en.wikipedia.org/wiki/Webdav]], ZiddlyWiki, [[MediaWiki|http://en.wikipedia.org/wiki/MediaWiki]], [[Socialtext|http://www.socialtext.com/]] or HTML scraping.
Many server architectures are [[REST|http://en.wikipedia.org/wiki/REST]] based, and TiddlyWiki server adaptors are particularly easy to create for common REST patterns. It is also possible to create TiddlyWiki server adaptors for severs with an [[XML-RPC|http://en.wikipedia.org/wiki/XML-RPC]] interface.
Server adaptors are registered by name in the global object {{{config.adaptors}}}. Each entry is a reference to an object constructor for that type of server adaptor. The adaptor object must implement the following methods:
* [[Adaptor.openHost]]
* [[Adaptor.openWorkspace]]
* [[Adaptor.getTiddler]]
* [[Adaptor.close]]
Additionally the adaptor may implement the following methods:
* [[Adaptor.getWorkspaceList]] (required to support the Import Tiddlers UseCase)
* [[Adaptor.getTiddlerList]] (required to support the Import Tiddlers UseCase)
* [[Adaptor.putTiddler]] (required to support the Sync UseCase)
* [[Adaptor.getTiddlerRevision]]
* [[Adaptor.getTiddlerRevisionList]]
The adaptor object is used through the life of a connection to a server; see [[ServerAdaptorConcepts]] for details. Many of the methods use an AsynchronousPattern of callbacks to deliver their results.
Custom formatters for the WikifierFormatterMechanism are often used alongside server adaptors to allow TiddlyWiki to display content in the native format of a server.
In TiddlyWiki you can implement scripts in JavaScript -- most of these are based on...
:» [[InlineJavascriptPlugin|Scripts]]
:» transclusion with evaluated parameters
<<list all>><<listfiltr>>
!Backstage Tabs
The following sample code adds the contents of [[SideBarOptions]] as a new backstage tab (called "myTab"):
{{{
config.tasks.myTab = {
text: "my custom tab",
tooltip: "A custom backstage tab",
content: "<<tiddler SideBarOptions>>"
};
config.backstageTasks.push("myTab");
}}}
!Command Buttons
In order to add a command button directly to the backstage bar, the ''action'' property should be used to reference a JavaScript function (no arguments are passed).
For example, the standard backstage button for ''Save'' is defined as follows:
{{{
save: {
text: "save",
tooltip: "Save your changes to this TiddlyWiki",
action: saveChanges
}
}}}
If the desired function does not have a convenient entry point, or if certain functions need arguments passed to them, an anonymous function declaration can be used as a "wrapper":
{{{
config.tasks.myTab = {
text: "username",
tooltip: "set your TiddlyWiki user name",
action: function() {
var newName = prompt("Please enter a new username:", config.options.txtUserName);
if(!newName || !newName.length)
return false; // canceled by user
config.options.txtUserName = newName;
saveOptionCookie("txtUserName");
}
};
config.backstageTasks.push("myTab");
}}}
!Other Elements
Adding content other than tabs or buttons to the backstage bar requires hijacking the [[backstage.init()]] function in order to render those elements directly into the ''backstageToolbar'' element.
{{annotation{
''Note'': While hijacking the core function is necessary for this purpose, it could corrupt the backstage if there is an error in the respective code. Since the backstage serves as a fallback mechnanism in case there are other problems, this should be used with caution.
}}}
For example, the following code adds the search box to the backstage toolbar (inside a container with the custom searchBox):
{{{
backstage.init_old = backstage.init;
backstage.init = function() {
var s = "{{searchBox{<<search>>}}}";
this.init_old.apply(this, arguments);
wikify(s, document.getElementById("backstageToolbar"));
};
}}}

Reply to this tiddler if you have a particular request for missing content or have content you wish to contribute but it doesn't as of yet have a tiddler covering it in this space.
All suggestions are greatly appreciated and will be displayed below.
{{right title{[[Core Macros]]}}}A [[macro|Macro]] provides predefined functions or operations that are performed when inserted into tiddler text. It is invoked whenever the tiddler is rendered and typically performs one of the fllowing actions...
*inserts computed content into the rendered text at the point where it is referenced
*manipulates or enhances any content that is so far rendered
Embedding a macro is done using the following markup...
;plain
: {{{<<macroName>>}}}
;w/ simple parameters
:{{{<<macroName paramValue1 paramValue2>>}}}
;w/ named parameters
:{{{<<macroName param1:value1 param2:'value2 with spaces'>>}}}
;w/ mixed parameters
:{{{<<macroName paramValue1 param2:[[value 2]]>>}}}
There are several standard macros built into the TiddlyWiki core. Many additional macros are available by installing plugins.
!Summary
Occasionally you want to add notes to your tiddler markup yet don't want it displayed when the tiddler is rendered. To achieve this, wrap the text using {{{/% hidden %/}}}.
!Example
{{{
text before .../%
!HIDDEN SECTION
This is content of a hidden section.
!END%/ text after
}}}
''Display as:''
<<<
text before /%
!HIDDEN SECTION
This is content of a hidden section.
!END%/... text after

!Description
The [[tags macro|tags]] outputs a list of [[Tags]] assigned to a tiddler.
!Usage
{{{
<<tags [TiddlerName]>>
}}}
!Parameters
Without parameters, the tags macro displays the tags for the current tiddler. Using some {{{Tiddler Name}}} as the optional first parameter, tags are listed for that tiddler instead.
{{annotation{
''Note'': Tags which themselves are tagged <<tag excludeLists>> are not displayed, e.g. if we have a tiddler called ''Foo'' which is tagged <<tag excludeLists>> and the tags macro is run on some other tiddler that has <<tag Foo>> as a tag, the tag <<tag Foo>> will not be displayed in the list.
}}}
!Example
{{{
<<tags "tag (macro)">>
}}}
<<tags "tag (macro)">>

''iTW Beta by Bidix''
BidiX has a iPhone optimized version of TiddlyWiki available here: http://itw.bidix.info/
''TW on iPhone using a data url bookmark''
I believe it's possible if you sync the bookmark from safari via iTunes. But you can't save. (Though save to url should be possible. Anyone thought about this?)
''Saving using virtual disk''
It is possible to store TiddlyWiki documents on a [http://groups.google.com/group/TiddlyWiki/browse_thread/thread/35d17fdd24c43391 virtual disk] on the iPhone or iPod Touch.

I've had the chance to play with TiddlyWiki on an iPhone. It works as a pretty perfect clone of the desktop Safari experience, with iPhone pinch-zoom goodness to make it navigable on the tiny display. The problems are:
* it takes ages to load; over EDGE it's excruciating, but even over wifi you have to be pretty patient
* even once it's loaded, JavaScript intensive actions can be painfully slow. For example, clicking on a tiddler link can take more than a second to open the target tiddler
* it doesn't seem possible to load the TW file from a file:// URL; therefore there is no obvious avenue to explore for saving changes locally
* the desktop UI although usable doesn't really work well on the tiny screen; built in iPhone apps like Mail show a more iPhone-native way of accomplishing some of the same things
The planned stripping back of the core code should improve the performance situation. It's possible that a solution to the saving problem will come in the form of a native iPhone app that wraps WebKit to provide a custom host for TiddlyWiki.
In the short term, I've started investigating a plugin to attack the last problem, optimising the TiddlyWiki UI for the iPhone. (Inspired by http://www.joehewitt.com/iui/)
Cheers

Jeremy mentions that it isn't possible to load the TW file from a file:// URL. This is because the iPhone (and iPod Touch) do not have a 'publicly accessible' file system and therefore the browser does not support the file:// protocol on these platforms.

It is possible to load a TW file from a file:// URL on jailbroken iPhones. There is a package on ModMyi.com that contains the [[http://modmyi.com/cydia/package.php?id=1387 file schema]]. With jailbroken iPhones, the full filesystem is accessible, through programs such as [[http://www.appleiphoneschool.com/openssh/ SSH]] or [[http://iphone.heinelt.eu/?Applications:iFile iFile]]. If you do use SSH, make sure you change the root password!

''Notes from Poul''
Some of us would argue that the iPhone is intended as a terminal for telephony and web access. You would store your notes on a server or 'in the cloud' using either of [[hosted|Server-Side Solutions]] solutions like TiddlyWeb or giewiki. That way, the sync problem is not a problem. I admit that with giewiki, I still need to focus on reducing the # of web requests.
Anyway, the biggest problem seems to be that since you don't have cursor keys, you can't scroll in edit boxes (or can you..yes: use 2 fingers & lors of patience).

[[Tiddlers|Tiddler]] can have attributes in the form of custom [[fields|Fields]]. A tiddler field can be any data that describe or extend the tiddler with dedicated information, e.g. geo data associated with a tiddler.
To view the fields of a tiddler, click on the more button in your toolbar and select the {{button{fields}}} option.
{{annotation{
''Note'': This tiddler has a custom field named {{{color}}} which could potentially be used by a plugin to set the text color.
}}}
In TiddlySpace you can programatically inspect tiddler fields via the [[TiddlySpace API]], e.g.:
* [[click to see the text serialization for this tiddler|http://tiddlywiki.tiddlyspace.com/bags/tiddlywiki_public/tiddlers/Custom Fields.txt]]
!"""Editing Fields"""
By default it is not possible to edit a custom field in TiddlyWiki. To enable editing install a plugin, e.g. [[FE2|http://tbgtd.tiddlyspot.com/#FE2]] or [[FieldsEditorPlugin|http://visualtw.ouvaton.org/VisualTW.html#FieldsEditorPlugin]]. In TiddlySpace, you can alternatively include the @first-class-fields space which as well provides field editing functions.
!"""Basic Viewing & Editing"""
First of all, custom field names must be all lower case in order to be stored and retrieved sucessfully.
The most simple way to create and edit a custom field is by modifying your shadow tiddlers called EditTemplate and ViewTemplate:
;EditTemplate
:{{{
<div>My Field: <span macro="edit my-field"></span></div>
}}}
;ViewTemplate
:{{{
<div>My Field: <span macro="view my-field"></span></div>
}}}
Now, when you view any tiddler, you will see the value of {{{my-field}}} for the corresponding tiddler and are able to edit and save a new value for it in edit mode.
If you want the values for your custom field to be rendered as wiki text, use the parameter {{{wikified}}} for the view macro in the ViewTemplate...
;ViewTemplate
:{{{
<div>My Field: <span macro="view my-field wikified"></span></div>
}}}
!"""Styling The Field Output"""
You can apply inline styles directly in your ViewTemplate, e.g.:
;ViewTemplate
:{{{
<div style="font-size:200%;">My Field: <span macro="view my-field"></span></div>
}}}
A better way is to use a class and to put the corresponding css code in your StyleSheet tiddler,e.g.:
;ViewTemplate
:{{{
<div class="my-field">My Field: <span macro="view mything"></span></div>
}}}
;StyleSheet
:{{sub{
{{{
.my-field {
color:white;
background: red;
border:3px solid green;
}
}}}
}}}
!"""Changing The Edit Box"""
Use css to change the size that comes with the edit box by default. you can do it with CSS, e.g.:
;EditTemplate
:{{{
<div><span class="my-box" macro="edit mything"></span></div>
}}}
;StyleSheet
:{{sub{
{{{
.my-box input {
width:100%;
}
}}}
}}}
!"""Display Fields Conditionally"""
To conditionally display custom fields you can install and use [[HideWhenPlugin|http://mptw.tiddlyspot.com/#HideWhenPlugin]].
Here's what you do to to conditionally show fields based on tags using HideWhenPlugin. Let suppose you have a some tiddlers tagged <<tag friend>> and you use a custom field to maintain some information about them, say their favourite food. To view and edit your friends' favourite food, add the following:
;ViewTemplate
:{{sub{
{{{
<div macro="showWhen tiddler.tags.contains('friend')">
Favourite food: <span macro="view favourite-food"></span>
</div>
}}}
}}}
;EditTemplate:
:{{sub{
{{{
<div macro="showWhen tiddler.tags.contains('friend')">
Favourite Food: <span macro="edit favourite-food"></span>
</div>
}}}
}}}
!"""Gathering Field Data"""
To list all your friends whose favourite food is pizza, you can install and use [[ForEachTiddlerPlugin|http://tiddlywiki.abego-software.de/#ForEachTiddlerPlugin]] from [[Udo Borowski|http://tiddlywiki.abego-software.de]].
Once installed, add this to a tiddler:
:{{sub{
{{{
<<forEachTiddler
where
' store.getValue(tiddler,"favourite-food") == "pizza" '
>>
}}}
}}}
This displays a bulleted list of tiddlers tagged <<tag friends>> whose favourite food is {{{pizza}}} -- saved in the custom field {{{favourite-food}}}.
For more information on how to customize the output, refer to the [[plugin documentation|http://tiddlywiki.abego-software.de/#ForEachTiddlerPlugin]].
!Summary
This prototype function the [[Story.class]] changes the location in the browsers' address bar to a permalink for all open tiddlers. Implemented by the permaview macro.
!Signature
{{{Story.prototype.permaView = function() {} }}}
!Returns
undefined
!Arguments
none
!Example
If you run...
{{{
permaview();
}}}
...with just this tiddler being open, then the address bar will change to...
{{{

}}}
This is a problem with Firebug for Firefox.
{{annotation{
Forget the below workaround: You can keep Firebug enabled. Switch to Firebug's "Net" tab and in the ''Options'' menu select "Disable Network Monitoring". This stops the problem from recurring when you try upload.

Firebug's console interferes with the browser's handling of ~XMLHttpRequest functions. The problem is triggered by selecting "Show ~XMLHttpRequests" from the Firebug Console "Options" menu (open Firebug to access the menu).
In the previous version of Firebug, disabling this menu option avoided the problem. However, as of Firebug v1.0.1, it seems that isn't enough, and the problem can appear even if the "Show..." menu it unchecked.
One workaround is to completely disable Firebug until needed. Another temporarily workaround is to toggle (i.e., set and then clear) the "Show ~XMLHttpRequests" menu item just before doing the upload. This stops Firebug from interferring in the NEXT ~XMLHttpRequest. Curiously, even though the menu item remains unchecked, any subsequent ~XMLHttpRequests will again fail until you toggle the menu again.

I did a test (2013-09-23) with:
* FireBug Version: 1.12.1
* FireFox Version: 24.0
* OS ubuntu 13.04
* http://a-pm-experimental.tiddlyspot.com/
** TW core version: 2.5.3
* FireBug is open
** Network tab is open, to see what's going on
I did create a new tiddler.
I did "save to web" -> Everything works as expected.

The //getTemplateForTiddler// method of the [[Story]] class returns HTML source code ready to be used as a template that is stored inside a tiddler. This method takes three parameters:
* the title of the tiddler that is about to be displayed
* the title of the tiddler containing the template source code. Note that the constants //~DEFAULT_VIEW_TEMPLATE// and //~DEFAULT_EDIT_TEMPLATE// do not work here.
* a reference to the Tiddler about to be displayed
Only the second parameter is actually used by the TiddlyWiki code, but the other information is passed for the benefit of plugin developers who override this method.
This page is meant as an overview of the basic TiddlyWiki architecture.

In a classic TiddlyWiki, tiddlers are primarily displayed and edited in the main story column at the center of the page. Tiddlers are pervasive in TiddlyWiki, most content is stored as a tiddler, like the MainMenu, even Plugins and StyleSheets.
Other systems may use more formal terms, e.g.""" "items" """,""" "entries" """,""" "entities" """ -- according to [[Jeremy Ruston|JeremyRuston]],""" "tiddler" """may undoubtedly be a silly name, but it has the virtue of being confusingly distinctive rather than confusingly generic.
!!Structure
<<tiddler 'Standard Field'>>
!![[Shadow Tiddlers|ShadowTiddler]]
Shadow tiddlers are tiddlers that provide default contents which also server as failproof fallbacks -- see ShadowTiddler.
!!"""Tiddler IDs"""
Every tiddler element as displayed by the browser and stored in the [[DOM]] has a unique identifier. This ID is composed of the string {{{tiddler}}} and the tiddler's name, e.g. {{{tiddlerGettingStarted}}}.

However, the tiddler will actually reside in your home space.
@TiddlyWikiDev will search TiddlySpace and pull in all the responses and show them as comments. This way, you can suggest changes and those suggestions can be discussed (if required) before making it into the actual documentation.
In order to be able to reply, you will need to be a member of tiddlyspace.
Please refer to the [[FUNCTION TEMPLATE]] when documenting a core function.
''TODO:'' Especially all functions that lack brackets at the end would probably profit from a rewrite.

<<tiddler "Developer Space">>
There are four basic stages in TiddlyWiki's startup process:
;oninit
:when ''main()'' starts
;onload
:after tiddlers have been loaded (including shadow tiddlers)
;onconfig
:right after plugins are loaded
;onstart
:when [[restarting|Dev.Restart]]
These are defined within the paramifier mechanism.

To save on space, TiddlyWiki users often host images externally on sites like Flickr and ImageShack. A URL or HTML code for the image is then pasted into a tiddler (including MainMenu and SiteTitle to display images in the menu and header respectively).
Open the tiddler, position the cursor where the image is to go and paste in the link using the following formatting:
'''URL'''
<nowiki>
[img[URL of image]]
</nowiki>
'''URL with alternate text and link'''
<nowiki>
[img[alternate text|URL of image][tiddler or URL]]
</nowiki>
'''HTML'''
<nowiki>
<html>HTML code from hosting site</html>
</nowiki>
''Image Hosting''
There are various free image hosting services which can be used to store pictures:
* [[TinyPic|http://tinypic.com/index.php]]
* [[ImageShack|http://www.imageshack.us]]

!ImportTiddlers Method
see [[Importing Tiddlers]]
!Copy & Paste Method
;Locate the plugin you want to install
* It's a good idea to get it from the plugin author's site so you know you have the latest version
;Copy the source of the plugin tiddler
* To do this you need to click the tiddler's 'edit' button. Sometimes instead of an 'edit' button there is a 'view' or 'source' button instead, but either way it should show you the source of the plugin tiddler.
* Click in the text box and do an "Edit", "Select All" from your browser menu, or press Ctrl-A (Cmd-A for Mac users) to select the entire contents. Often the tiddlers contents is already selected for you so you may be able to skip this step.
* Do an "Edit", "Copy", or press Ctrl-C (Cmd-C for Mac users) to copy the entire contents of the tiddler.
;Create the plugin tiddler in your TiddlyWiki
* Back in your own TiddlyWiki, click 'new tiddler' to create a tiddler.
* You can name the tiddler anything you like but to save confusion give it the same as the plugin you are installing.
* Do an "Edit", "Paste", or Ctrl-V/Cmd-V to paste the plugin source code into your new plugin tiddler.
* (Note if you updating a plugin you already have you can just edit it, do a select all, delete to clear the contents before you paste in the new contents).
;Add the "systemConfig" tag
* Before you save the new plugin tiddler, add the tag "systemConfig" to the tags box. It must start with a lowercase 's'. This is what tells TiddlyWiki to execute the code in the plugin tiddler when starting.
;Save and reload
* The plugin is not active until you save and reload your TiddlyWiki so click 'save changes', then click reload in your browser.
;Testing
* Now your plugin should be active and working. Check that it is doing what it should be doing.
!Troubleshooting
cf. [[Troubleshooting]]
;If it's not working but you don't get an error
Check the following
* Did you remember the systemConfig tag? It must be spelt correctly and it is case sensitive.
* Did you save and reload?
;You get javascript error messages (check your Javascript Console in Firefox)
* It means that there are errors in the plugin code.
* Check that you copied the entire plugin source code and that you clicked edit (or view or source) before copying.
* It's possible that the plugin is buggy. If you email the plugin author or post to the TiddlyWiki Google Group you may get some help. Mention your browser your OS and the details of the problem you're having.
The tiddler is the basic, self-contained element in TiddlyWiki and is defined by a set of standard fields.
It is a piece of micro-content which can contain human readable content based on [[TiddlyWiki Markup]] or other text based formats, [[binary data|Binary Tiddler]], CSS for StyleSheets or JavaScript in the form of [[plugins|Plugins]].
In TiddlySpace, each tiddler is saved in a [[bag|Bag]] and may be accessed through the TiddlyWeb [[HTTP API]], e.g. a text version of this tiddler can be retrieved using: http://tiddlywiki.tiddlyspace.com/Tiddler.txt
If you are going to work on some topic for longer, please list it under [[DOC - Review]] to indicate others that YOU are currently working on this. Remove when you're done.

Plugins enhancing tagging...
By default, some [[TiddlyWiki Markup]] such as lists or tables do not allow multi-line content. However, workarounds exist to achieve this nontheless.
!Custom CSS Class Wrapper
See section ''Custom CSS Class Wrapper'' in [[TiddlyWiki Markup]]...
The most simple and versatile method to use multi-line content in a list element is by using a (dummy) custom CSS class wrapper, e.g.:
<html><pre>
#item 1
#{{multiLine{
!!!Heading
Some content.
}}}
# item 3
</pre>
<ol>
<li>item 1</li>
<li>
<h3>Heading</h3>
<p>Some content.</p>
</li>
<li>item 3</li>
</ol></html>{{annotation{
''Note'': You are not required to actually define the respective css class in your StyleSheet.
}}}
!"""Manual Line Breaks"""
Especially in tables, a manual line break can be used, e.g.:
{{{
|!foo|bar<br>baz|
}}}
|!foo|bar<br>baz|
The same can be achieved using [[CoreTweak #831 from TiddlyTools|http://tiddlytools.com/#CoreTweaks]] and the following syntax:
{{{
|!foo|bar\\
baz|
}}}
Create a line break simply by appendind two backslashes at the end of a line without breaking the list or table format.
{{annotation{
''Note'': A [[TiddlyTools CoreTweak|http://tiddlytools.com/#CoreTweaks]] can be installed either by importing the whole [[CoreTweaks|http://tiddlytools.com/#CoreTweaks]] plugin or by appending the desired [[CoreTweak|http://tiddlytools.com/#CoreTweaks]] to your [[zzConfig]].
}}}
!"""Using Transclusion"""
You can use the [[tiddler macro|tiddler]] to transclude (embed) multi-line into a tiddler by fetching it from another tiddler, e.g.:
{{{
# item 1
# <<tiddler [[item 2]]>>
# item 3
}}}
!!!Partial Transclusion
You can as well transclude a hidden section of the same tiddler, e.g ''~SomeTiddler'' might contain:
{{{
|Foo|<<tiddler [[SomeTiddler##LOREM]]>>|
|Bar|<<tiddler [[SomeTiddler##IPSUM]]>>|
/%
!LOREM
Lorem ipsum dolor sit amet.
!IPSUM
Consectetur adipisicing elit.
!END%/
}}}
|Foo|Lorem ipsum dolor sit amet.|
|Bar|Consectetur adipisicing elit.|
{{annotation{
''Note:'' Fore hidden sections, use uppercase """SECTION TITLES""" to easily identify that it's a hidden section.
}}}
!"""MediaWiki Formatter"""

First, set up a CSS rule to do the justification. Add something like
this to your StyleSheet tiddler (find it on tab More => Shadowed):
{{{
.justifyright {
text-align: right;
}
}}}
that gives you a css class of justifyright that you can use to make
stuff be right-aligned. Make sure you get the dot at the start of
".justifyright".
Now, edit some tiddler and put the stuff you want to justify inside
triple-curly-brackets, with the CSS class after the first two. You
will need to put the brackets on lines by themselves.
{{justifyright{
This paragraph will be right-aligned.
}}}
If you want full justification, add a CSS rule like this, and then use
"justifyfull" inside the triple curlies:
{{{
.justifyfull {
text-align: justify;
}
}}}
Note that '''this won't work''' if you use the triple curlies inline:
{{{
{{justifyright{ DOESN'T WORK: This is not right justified }}}
}}}
{{justifyright{ DOESN'T WORK: This is not right justified }}}
This is because triple curlies make spans if you use them inline
<nowiki>{{{like this}}}</nowiki>, but divs if you use them on lines by themselves.

The ''getTiddler'' method of the [[story]] class returns the DOM element of a tiddler displayed in the story. It takes one parameter, the name of a tiddler.
If the given name isn't currently displayed then it will return ''null''
It can be used like so
{{{
story.getTiddler("GettingStarted");
}}}
The edit mode refers to the mode of editing a rendered tiddler.
By default, how a tiddler is displayed in edit mode is defined by one of the shadow tiddlers that control the layout of TiddlyWiki called [[EditTemplate]].

As of Firefox beta 25 on Android 4.3, you can...
#download the latest version of TiddlyFox from Github using Chrome from
#*https://github.com/TiddlyWiki/TiddlyFox/raw/master/tiddlyfox.xpi
#go to your download folder using a file manager app, like OI file manager
#since the file manager wont open the ''.xpi'', copy or remember the path
#in Firefox, open / paste the path pointing to the local ''tiddlyfox.xpi''
#*for example: {{{file:///storage/emulated/0/Download/tiddlyfox.xpi}}}

By default, Chrome doesn't save *local* cookies (i.e., cookies associated with locally-stored files, such as TW documents).
Fortunately, there is a command line option, {{{--enable-file-cookies}}}, that you can use to force Chrome to accept local cookies. All you need to do is edit the properties for the icon you use to launch Chrome, and add the option to the end of the "target" field, like this:
{{{

The ''setDirty'' method of the [[Story]] class sets the dirty flag of a single tiddler, which indicates whether it contains unsaved changes. It takes two parameters:
* the title of the tiddler
* the boolean value to set the dirty flag to
This method does not return any value.
For example to set this tiddler to dirty you would do the following:
{{{
story.setDirty('Story.setDirty', true);

This function of the <<tag Tiddler "Tiddler Class">> determines whether a tiddler has been changed, e.g. edited, since it was last saved.
!Signature
{{{Tiddler.prototype.isTouched = function() {} }}}
!Returns
boolean: {{{true}}} means the tiddler was modified
!Arguments
none
!Example
Assume ''"""some tiddler"""'' has been modified, yet not [[persisted|Persistence]]...
{{{

[[Slices]] are little chunks of information that can be referenced in another tiddler. A slice is a {{{name:value}}} pair that can be specified anywhere in a tiddler using one of the following notations:
{{{
name: value
|name:|value|
|name|value|
}}}
Leading and trailing blanks are stripped.
* It is not possible to import from TiddlyWiki's on servers which are not [[CORS|http://en.wikipedia.org/wiki/Cross-Origin_Resource_Sharing]] enabled. Popular sites such as [[TiddlyTools|http://tiddlytools.com]] are currently not CORS enabled. Fortunately this is fixable - webmasters can enable their sites to be CORS enabled by following the instructions [[here|http://enable-cors.org]] and if a website is not CORS enabled you can e-mail the owner to tell them the problem
* Some browsers will only allow you to import from TiddlyWikis in the same directory as your TiddlyWiki. If you use Chrome you can enable this by modifying the Chrome shortcut to include the following parameter
{{{
--allow-file-access-from-files
}}}
* Note some browsers, notably Opera do not support import / upgrade in any form.
In a classical TiddlyWiki, the UserName as entered in the OptionsPanel in the sidebar is saved to the [[modifier field|Fields]] when saving edits to a [[tiddler|Tiddler]].
It can be used to enable low level access restrictions when the wiki is viewed by anyone over http, see [[How to use TiddlyWiki as a Website?]]

We have various endeca rules set up through Rules Manager in our application which are triggered while rendering the page.
Is it possible to determine which rule was triggered for a page through Java/JSP code?
share|improve this question
up vote 2 down vote accepted
The proper way to do this is with the Content Assembler API (endeca_content.jar). You need to create a content query and retrive the content object:
ContentItem content = results.getContent();
content.getName();
It is also possible to use the navigation API, using the SupplementList object from the navigation object: The title key will represent the name of the rule triggered. However, is you are using page builder in any meaningful way the proper approach is to use the Content Assemble API.
SupplementList sl = nav.getSupplements();
for (Object object : sl) {
Supplement s = (Supplement) object;
PropertyMap map = s.getProperties();
Set keys = map.keySet();
for (Object key : keys) {
logger.info("Sup prop: " + key + " \t" + map.get(key));
}
}

Stack Overflow is a question and answer site for professional and enthusiast programmers. It's 100% free, no registration required.
I was wondering, what is there any different, on various ways to initialize static final variable?
private static final int i = 100;
or
private static final int i;
static {
i = 100;
}
Is there any different among the two?
share|improve this question

If you're only setting variables, both forms are equivalent (and you should use the former as it is more readable and succinct).
The static {} form exists for cases where you also need to execute statements other than variable assignments. (Somewhat contrived) example:
private static final int i;
static {
establishDatabaseConnection();
i = readIntFromDatabase;
closeDatabaseConnection();
}
share|improve this answer
The main reason for the static blocks are to be able to add some logic to the initialization that you cannot do in the 1 line initialization, like initializing an array or something.
share|improve this answer
Yes, by using the second way you are able to use a try...catch block and react to exceptions where as with the first way declared exceptions cannot be catched.
There is also a difference when at class init the fields and die static block is executed but I have no details, see language specification on class instantiation for more information.
Greetz, GHad
share|improve this answer
For a primitive variable, nothing. The difference can be if the initialization is not trivial, or the init method / constructor throws a checked exception - then you need a static block in order to be able to handle the exception.
share|improve this answer
They are the same except you can write multiple lines in the static code block.
See java's official turorial.
share|improve this answer
You could also use Forward Reference initialization
public class ForwardReference {
private static final int i = getValue();
private static final int j = 2;
public static void main(String[] args) {
System.out.println(i);
}
private static int getValue() {
return j*2;
}
}
The key here is that we are getting value of 'j' from 'getValue' before 'j' have been declared. Static variables are initialized in order they appear.
This will print correct value of '4'
share|improve this answer
This is amazing. However, I changed "j = 2" to "j = j()" and added "static int j(){return 2;}". With these changes ForwardReference print '0'. So there appears to be some limits to Forward Reference. – emory Jul 3 '10 at 21:51

Edit the text styles and text properties using the expression controls.
Use expressions to control text styling in any text expression or in Motion Graphics templates. Some things you can do with expressions are:
• Link multiple titles and update their styles at once (very useful for designing titles).
• Keep font, size, and styling in sync across multiple Text layers.
• Make global changes to text properties.
• Set style attributes of individual characters in a Text layer. (Beta)
Once you set these for a Text layer, reference that layer's properties to easily apply changes throughout the composition. After Effects expressions use properties to read (get) text style values and function methods to write (set) them inside the expression engine. This allows you to link text styles across Text layers or set up controls for them to be animated or used in a Motion Graphics template.
Before you start using expressions to edit text properties
1. Set Expressions Engine to Javascript by selecting Project Settings > Expressions > Expressions Engine > Javascript.
2. Add an expression to a Text layer's Source Text property.
3. In the Expression Language flyout menu, select Text > Properties > Text Properties or Text > Styling (Beta).
Available text attributes
The following text styling attributes can be read and set using the style object:
• Font
• Font Size
• Faux Bold
• Faux Italics
• All Caps
• Small Caps
• Tracking
• Leading
• Auto Leading
• Baseline Shift
• Fill (enable/disable)
• Fill Color
• Stroke (enable/disable)
• Stroke Color
• Stroke Width
• Digit Set (Beta)
• Scaling (Beta)
• Kerning (Beta)
• Tsume (Beta)
• Baseline Direction (Beta)
• Baseline Option (Beta)
Expression Language flyout menu lists all Text Properties to choose from.
The Expression Language flyout menu lists all Text Properties, including ones currently in After Effects Beta.
The Source Text property of a Text layer is interpreted by expressions as a JavaScript string. The text itself can be read with sourceText, but it must be set on the style object with the setText method if style attributes are being modified. Go through some of the examples.
Expressions for text layers with paragraphs
Start a new line of text
Use \r in a string expression to start a new line of text. For example, to copy the original text from one layer onto the same layer and repeat it in all uppercase characters on a new line, use the following expression:
text.sourceText + "\r" + text.sourceText.toUpperCase()
Available paragraph attributes
Paragraph styling in Expressions is now available for testing and feedback. Try it now in After Effects (Beta).
In addition to text style attributes, there are also paragraph attributes. These can only be applied to the entire Text layer. The paragraph attributes are only available in After Effects (Beta).
• Direction
• Every-Line Composer
• First Line Indent
• Justification
• Leading Type
• Left Margin
• Right Margin
• Space After
• Space Before
• Hanging Roman Punctuation
The Expression Language flyout menu lists all Paragraph Properties, including ones currently in After Effects Beta.
The Expression Language flyout menu lists all Paragraph Properties included in After Effects Beta.
Learn more about these new expressions in After Effects (Beta) Community.
PostScript font expression menu
When referring to fonts in expressions, they must use a special "system name" ( or similar ). It is recommended to insert this special name from the Text > Font > Select Font dialog to avoid expression errors.
• Open the Expression Language flyout menu, then select Text > Font. This brings up a dialog with drop-down menus to select the typeface and font to insert into the expression.
Font menu
Use the Expression Language menu to select the typeface and font to insert into the expression.
Font syncing
Fonts that are only referred to in the Expressions Editor are not recorded as fonts used by the project. To ensure all fonts referred to in the Expressions Editor will auto-sync or populate the Resolve Fonts dialog, use all of those fonts on a layer, even if that layer source is hidden.
Fonts Used
The Resolve Fonts dialog box might appear if the expressions refer to fonts that are not installed on your system.
Style object
All of the styling properties for a Text layer exist on the style object, which is accessed on the Source Text property using the following:
// Using the whole path to the Source Text property
text.sourceText.style
// Using the generic name for the current property
thisProperty.style
Using style by itself is the same as using either of the two examples above, but this can be confusing if style attributes from multiple Text layers are being combined.
The styling attributes of other Text layers can also be read. Use the pick whip to create a link to the other Text layer at the beginning of the first example shown above.
// Accessing the style object of a specific text layer
thisComp.layer("Other Layer Name").text.sourceText.style;
Style attributes of individual characters in a Text layer
Per-character text styling in Expressions is now available for testing and feedback. Try it now in After Effects (Beta).
In addition to using text expressions to set style attributes of the entire Text layer, you can also set style attributes of individual characters in the layer. A benefit of this per-character control is automatic reflowing of text, such as when scaling letters, using superscript, and using a different font, just as you would expect from using substring styling from the Character panel.
Examples
Change the font for certain words
text.sourceText.style
.setFont("Montserrat-Light")
.setFont("Gigantic", 0, 6).setFont("Gigantic", 10, 6).setFont("Gigantic", 20)
Set the first line of a text layer to bold and make it larger
text.sourceText.style.setFontSize(100, 0, 30).setFauxBold(true, 0, 30)
Set superscript for characters
To use the string, add a Text layer with '1st and 2nd Place' text and apply the following to the Source Text.
text.sourceText.style.setBaselineOption("superscript",1,2).setBaselineOption("superscript", 9, 2)
Combine style and source text
text and style
Combining Style and Source Text
To return the values of both the style and the actual Source Text at time, you will have to combine the getStyleAt and setText functions. Below are two examples of how to write this expression.
// To return the values of both the style and the actual Source Text at time (short hand)
var sourceTextProperty = thisComp.layer("MAIN TEXT").text.sourceText;
var newStyle = sourceTextProperty.getStyleAt(0,0);
newStyle.setText(sourceTextProperty);
// To return the values of both the style and the actual Source Text of the previous layer in the layer stacking order
var sourceTextProperty = thisComp.layer(index - 1).text.sourceText;
var newStyle = sourceTextProperty.getStyleAt(0,0);
newStyle.setText(sourceTextProperty);
dropdown fonts
Link Fonts or Styles to a Dropdown Menu
You can use Dropdown menus to control text styles, such as locking Text layers to specific fonts. This is useful for brand guidelines, templates, MoGRTS, and more:
// To lock a text layer to specific fonts with a Dropdown Menu Control
var dropDownMenu = thisComp.layer("LayerName").effect("Dropdown Menu Control")("Menu");
switch (dropDownMenu.value) {
case 1 :
text.sourceText.style.setFont("Georgia");
break;
case 2 :
text.sourceText.style.setFont("Impact");
break;
default :
text.sourceText.style.setFont("Tahoma");
}
Main text layer
master text layer
Get text properties from “Text Layer 1” but override Font Size and Fill Color
Link multiple Text layers to a main font controller to control the text style of multiple layers at once. Create two Text layers, and paste this expression into the Source Text of one of them:
// To get all text properties from a text layer
thisComp.layer("Text Layer 1").text.sourceText.style;
It's possible to get the style from a Text layer but override specific text properties by adding values with the set functions. Below are two examples using Fill Color and Font Size.
// To get all text properties from “Text Layer 1” but override Fill Color and Font Size with hardcoded values
var newStyle = thisComp.layer("Text Layer 1").text.sourceText.style;
newStyle.setFillColor(hexToRgb("FF0000")).setFontSize(100);
// To get all text properties from "Text Layer 1” but override Fill Color and Font Size with the layer’s current text properties
var newStyle = thisComp.layer("Text Layer 1").text.sourceText.style;
var currentFillColor = thisProperty.style.fillColor;
var currentFontSize = thisProperty.style.fontSize;
newStyle.setFillColor(currentFillColor).setFontSize(currentFontSize);
Examples
The following are examples for how to access and use text property values with expressions.
Font
The following are examples for accessing a Text layer's Font, Font Size, Faux Bold, Faux Italic, Tracking, and Leading:
// To return the name of the Font for the text layer itself
text.sourceText.style.font;
// To return the name of the Font another text layer is using
var otherLayer = thisComp.layer("Other Layer Name");
otherLayer.text.sourceText.style.font;
// To return the value of Font Size for the text layer itself
text.sourceText.style.fontSize;
// To return the value of Font Size for another text layer
var otherLayer = thisComp.layer("Other Layer Name");
otherLayer.text.sourceText.style.fontSize;
// To return a Boolean value of whether a layer's text is Faux Bold or not (True or False)
text.sourceText.style.isFauxBold;
// To return a Boolean value of whether a layer's text is Faux Italic or not (True or False)
text.sourceText.style.isFauxItalic;
// To return the value of a text layer’s Tracking as a number
text.sourceText.style.tracking;
// To return the value of a text layer's Leading as a number
text.sourceText.style.leading;
Fill
The following are examples for accessing a Text layer's Fill and Fill Color:
// To return a Boolean value of whether a layer's text has Fill applied to it (True or False)
text.sourceText.style.applyFill;
// To return the value of the Fill Color of a text layer
// By default, this returns an array of the RGB values on a scale from 0 – 1.0
text.sourceText.style.fillColor;
// Set the Fill Color of a text layer with setApplyFill and setFillColor
// setFillColor values are defined as an RGB array on a scale between 0 – 1.0
var newStyle = style.setApplyFill(true);
newStyle.setFillColor([1.0, 1.0, 1.0]);
// Set the Fill Color of a text layer substituting the 0 – 1.0 RGB array with hexToRGB to define the color values with Hex values
var newStyle = style.setApplyFill(true);
newStyle.setFillColor(hexToRgb("FFFFFF"));
Fill RGB Values
// To return the red (R) value of the Fill Color
text.sourceText.style.fillColor[0];
Opmerking:
To return the value of the Fill Color for R, G, or B of a text layer, add 0, 1, or 2 in brackets, respectively.
Stroke
The following are examples for accessing a Text layer's Stroke, Stroke Color, and Stroke Width:
// To return a Boolean value of whether a layer's text has Stroke applied to it (True or False)
text.sourceText.style.applyStroke;
// To return the value of the Stroke Color of a text layer
// By default, this returns an array of the RGB values on a scale from 0 – 1.0
text.sourceText.style.strokeColor;
// Set the Stroke Color of a text layer with setApplyStroke and setStrokeColor
// setStrokeColor values are defined as an RGB array on a scale between 0 – 1.0
var newStyle = style.setApplyStroke(true);
newStyle.setStrokeColor([1.0, 0.0, 0.0]);
// Set the Stroke Color of a text layer substituting the 0 – 1.0 RGB array with hexToRGB to define the color values with Hex values
var newStyle = style.setApplyStroke(true);
newStyle.setStrokeColor(hexToRgb("FF0000"));
// To return the value of a text layer's Stroke Width as a number
text.sourceText.style.strokeWidth;
Stroke RGB Values
// To return the green (G) value of the Stroke Color
text.sourceText.style.strokeColor[1];
Opmerking:
To return the value of the Stroke Color for R, G, or B of a Text layer, add 0, 1, or 2 in brackets, respectively.
getStyleAt function
Use this get function to return the style value of a particular character at a specific time. index should be a number, the index of the letter or character whose style is needed. atTime should also be a number, the time within the composition to get the style from in case the style is keyframed and changes over time.
text.sourceText.getStyleAt(index, atTime);
Opmerking:
Using text.sourceText.style is the same as using text.sourceText.getStyleAt(0,0).
// Gets the style of the first character at the beginning of the timeline
text.sourceText.getStyleAt(0,0);
Set functions
Additional set functions that can be used individually or in combination with one another to drive styles across layers. Each of these functions are called on the style object of a Source Text property:
// Set the font used to Arial
style.setFont("ArialMT")
// Set the font size to 80
style.setFontSize(80);
// Enable Faux Bold with a Boolean
style.setFauxBold(true)
// Enable Faux Italics with a Boolean
style.setFauxItalics(true)
// Enable All Caps with a Boolean
style.setAllCaps(true)
// Enable Small Caps with a Boolean
style.setSmallCaps(true)
// Set the Tracking as a number
style.setTracking(10);
// Set the Leading as a number
style.setLeading(10);
// Enable Auto Leading with a Boolean
style.setAutoLeading(true);
// Set the Baseline Shift as a number
style.setBaselineShift(10);
// Set the Stroke Width as a number
style.setStrokeWidth(10);
// Currently in Beta - Set the first line of a text layer to bold and make it larger
text.sourceText.style.setFontSize(100, 0, 30).setFauxBold(true, 0, 30)
// Currently in Beta - Sets uperscript for characters
text.sourceText.style.setBaselineOption("superscript",1,2).setBaselineOption("superscript", 9, 2)
All of the set functions for text styles can be chained together to easily set multiple attributes without having to declare a new style each time, as in the following example:
Opmerking:
There is no semicolon used until the very last attribute is set. Listing each attribute on its own line helps make the whole chain easier to read.
// Enable Fill, set Fill Color, set Baseline, set Tracking, and enable Auto Leading
text.sourceText.style
.setApplyFill(true)
.setFillColor(hexToRgb("FFFFFF"))
.setBaselineShift(10)
.setTracking(25)
.setAutoLeading(true);
Additional uses for expressions on source text
Adding a Text layer to a composition and adding an expression to its Source Text property can be a great way to examine the property values of other layers. For example, the following expression on a Source Text property reports the name and value of the Opacity property for the next layer in the layer stacking order:
var nextLayer = thisComp.layer(index + 1);
nextLayer.name + "\rOpacity = " + nextLayer.opacity.value;
The following example reports the name of the footage item used as the source of the topmost image layer in the stacking order at the current time that has its Video switch set:
// Create sourceFootageName as a blank string
var sourceFootageName = "";
// Loop through all layers in the composition
for (var i = 1; i <= thisComp.numLayers; i++) {
// If i matches this layer's index, continue to next loop
if (i == index) {
continue;
}
// Set myLayer for the current iteration of the loop
var myLayer = thisComp.layer(i);
// If myLayer has no video or isn't active, continue to next loop/layer
if ( !myLayer.hasVideo || !myLayer.active ) {
continue;
}
// If myLayer is active at the current time
if ( myLayer.active ) {
try {
// Set sourceFootageName to myLayer's source name
sourceFootageName = myLayer.source.name;
} catch ( err ) {
// If myLayer has no source,
// set sourceFootageName to the myLayer's name
sourceFootageName = myLayer.name;
}
// Stop looping
break;
}
}
// Display the sourceFootageName
sourceFootageName;
Save expressions as presets
Select the Source Text property with expressions added to it. Then, select Animation > Save Animation Preset to reuse the expressions in other projects. Animation Presets are saved in the Effects & Presets panel.
For more information, see Effects and animation presets overview.

I'm new to facelets and I have generated a project using netbeans but I struggling with the tag.
I have
<h:selectOneMenu id="country" value="#{organisation.organisation.country}" title="Country" >
<f:selectItems value="#{country.countryItemsAvailableSelectOne}"/>
</h:selectOneMenu>
In the select I get classpath.Country[iso=GB] which I can see is an object but I really want to see the the country.prinableName value. I've looked at this for half a day and have drawn a blank Thanks for any help

JSF 1.x or 2.x? – BalusC Sep 8 '11 at 21:26
3 Answers 3
Since you're talking about Facelets, I'll assume JSF 2.x.
To start, HTML is one and all String. JSF generates HTML. By default, non-String Java objects are by toString() method converted to their String representation while JSF generates the HTML. To properly convert between those Java objects and String, you need a Converter.
I assume that your Country object has already the equals() method properly implemented, otherwise validation will later fail with "Validation error: Value not valid" because the selected object doesn't return true on testing the equals() for any of the available items.
I'll also make a little change in the naming since #{country} is a confusing managed bean name because it does apparently not represent an instance of the Country class. I'll call it Data which should hold application wide data.
@ManagedBean
@ApplicaitionScoped
public class Data {
private static final List<Country> COUNTRIES = populateItSomehow();
public List<Country> getCountries() {
return COUNTRIES;
}
// ...
}
I'll assume that the Country class has two properties code and name. I'll assume that the managed bean which receives the selected country has a private Country country property. In your <f:selectItems>, you need to loop over #{data.countries} and specify the country object as item value and the country name as item label.
<h:selectOneMenu value="#{bean.country}">
<f:selectItems value="#{data.countries}" var="country" itemValue="#{country}" itemLabel="#{country.name}" />
</h:selectOneMenu>
Now, you need to create a Converter for the Country class. We'll convert based on the country code which is unique for every country (right?). In the getAsString() you implement code which converts the Java object to its unique String representation which is to be used in HTML. In getAsObject() you implement code which converts the unique HTML String representation back to the Java object.
@FacesConverter(forClass=Country.class)
public class CountryConverter implements Converter {
@Override
public String getAsString(FacesContext context, UIComponent component, Object value) {
return (value instanceof Country) ? ((Country) value).getCode() : null;
}
@Override
public Object getAsObject(FacesContext context, UIComponent component, String value) {
if (value == null) {
return null;
}
Data data = context.getApplication().evaluateExpressionGet(context, "#{data}", Data.class);
for (Country country : data.getCountries()) {
if (country.getCode().equals(value)) {
return country;
}
}
throw new ConverterException(new FacesMessage(String.format("Cannot convert %s to Country", value)));
}
}
The @FacesConverter will register it automatically in JSF and JSF will automatically use it whenever it encounters a value expression of the Country type. Ultimately, you end up with country code as item value and country name as item label. JSF will convert the submitted country code back to a fullworthy Country object upon form submission.
In JSF 1.x the principle is not much different. In this blog you can find two basic kickoff examples: Objects in h:selectOneMenu.

Thank you all your assumptions correct and a great explanation will work through the example it will help me else where as well – user845854 Sep 8 '11 at 23:23
What happened to you, selectOneMenu call the toString() method for all given objects.
You've to use selectitems or a simple converter to manage that. A very simple example:
price.xhtml:
<h:selectOneMenu id="priceMenu" value="#{priceBean.selectedPrice}">
<f:selectItems value="#{priceBean.prices}" />
</h:selectOneMenu>
PriceBean.java:
..
private String selectedPrice;
..
public String getSelectedPrice() {
return selectedPrice;
}
public void setSelectedPrice(String newPrice) {
selectedPrice = newPrice;
}
..
public List<SelectItem> getPrices() {
List<SelectItem> retVal = new ArrayList<SelectItem>();
retVal.add(new SelectItem("2"));
retVal.add(new SelectItem("4"));
retVal.add(new SelectItem("6"));
return retVal;
}
Further informations about the SelectItem. If you want to use a specially object directly, for example an object called Price, you have to use a converter. Here an example is shown and here.

Thank you for the help I have it sorted using both the answers here. Thank you again for the tips. – user845854 Sep 8 '11 at 23:24
If you add editable="true" in your
<h:selectOneMenu value="#{bean.country}">
Then you'll get an unexpected String value (not from getAsString()) in the converter method:
public Object getAsObject(FacesContext context, UIComponent component, String value) { }

How can I recognize when plugins.fireHook is throwed?
• GNU/Linux
I need to recognize when the hook is fire in the pages, because for some pages in my plugin I need to do something.
plugins.fireHook('filter:topics.get', {topics: topics, uid: uid}, next);
is there some method that I can use to do this?
• You can use the filter:<templateName>.build hooks. For the category page it would be filter:category.build, for a topic page it would be filter:topic.build and so on.

Excursion 4: Objectivity and Auditing (blurbs of Tours I – IV)
.
Excursion 4 Tour I: The Myth of “The Myth of Objectivity”
Blanket slogans such as “all methods are equally objective and subjective” trivialize into oblivion the problem of objectivity. Such cavalier attitudes are at odds with the moves to take back science The goal of this tour is to identify what there is in objectivity that we won’t give up, and shouldn’t. While knowledge gaps leave room for biases and wishful thinking, we regularly come up against data that thwart our expectations and disagree with predictions we try to foist upon the world. This pushback supplies objective constraints on which our critical capacity is built. Supposing an objective method is to supply formal, mechanical, rules to process data is a holdover of a discredited logical positivist philosophy.Discretion in data generation and modeling does not warrant concluding: statistical inference is a matter of subjective belief. It is one thing to talk of our models as objects of belief and quite another to maintain that our task is to model beliefs. For a severe tester, a statistical method’s objectivity requires the ability to audit an inference: check assumptions, pinpoint blame for anomalies, falsify, and directly register how biasing selection effects–hunting, multiple testing and cherry-picking–alter its error probing capacities.

Excursion 4 Tour II: Rejection Fallacies: Whose Exaggerating What?
We begin with the Mountains out of Molehills Fallacy (large n problem): The fallacy of taking a (P-level) rejection of H0 with larger sample size as indicating greater discrepancy from H0 than with a smaller sample size. (4.3). The Jeffreys-Lindley paradox shows with large enough n, a .05 significant result can correspond to assigning H0 a high probability .95. There are family feuds as to whether this is a problem for Bayesians or frequentists! The severe tester takes account of sample size in interpreting the discrepancy indicated. A modification of confidence intervals (CIs) is required.
It is commonly charged that significance levels overstate the evidence against the null hypothesis (4.4, 4.5). What’s meant? One answer considered here, is that the P-value can be smaller than a posterior probability to the null hypothesis, based on a lump prior (often .5) to a point null hypothesis. There are battles between and within tribes of Bayesians and frequentists. Some argue for lowering the P-value to bring it into line with a particular posterior. Others argue the supposed exaggeration results from an unwarranted lump prior to a wrongly formulated null.We consider how to evaluate reforms based on bayes factor standards (4.5). Rather than dismiss criticisms of error statistical methods that assume a standard from a rival account, we give them a generous reading. Only once the minimal principle for severity is violated do we reject them. Souvenir R summarizes the severe tester’s interpretation of a rejection in a statistical significance test. At least 2 benchmarks are needed: reports of discrepancies (from a test hypothesis) that are, and those that are not, well indicated by the observed difference.

Excursion 4 Tour III: Auditing: Biasing Selection Effects & Randomization
Tour III takes up Peirce’s “two rules of inductive inference”: predesignation (4.6) and randomization (4.7). The Tour opens on a court case transpiring: the CEO of a drug company is being charged with giving shareholders an overly rosy report based on post-data dredging for nominally significant benefits. Auditing a result includes checking for (i) selection effects, (ii) violations of model assumptions, and (iii) obstacles to moving from statistical to substantive claims. We hear it’s too easy to obtain small P-values, yet replication attempts find it difficult to get small P-values with preregistered results. I call this the paradox of replication. The problem isn’t P-values but failing to adjust them for cherry picking and other biasing selection effects. Adjustments by Bonferroni and false discovery rates are considered. There is a tension between popular calls for preregistering data analysis, and accounts that downplay error probabilities. Worse, in the interest of promoting a methodology that rejects error probabilities, researchers who most deserve lambasting are thrown a handy line of defense. However, data dependent searching need not be pejorative. In some cases, it can improve severity. (4.6)
Big Data cannot ignore experimental design principles. Unless we take account of the sampling distribution, it becomes difficult to justify resampling and randomization. We consider RCTs in development economics (RCT4D) and genomics. Failing to randomize microarrays is thought to have resulted in a decade lost in genomics. Granted the rejection of error probabilities is often tied to presupposing their relevance is limited to long-run behavioristic goals, which we reject. They are essential for an epistemic goal: controlling and assessing how well or poorly tested claims are. (4.7)

Excursion 4 Tour IV: More Auditing: Objectivity and Model Checking
While all models are false, it’s also the case that no useful models are true. Were a model so complex as to represent data realistically, it wouldn’t be useful for finding things out. A statistical model is useful by being adequate for a problem, meaning it enables controlling and assessing if purported solutions are well or poorly probed and to what degree. We give a way to define severity in terms of solving a problem.(4.8) When it comes to testing model assumptions, many Bayesians agree with George Box (1983) that “it requires frequentist theory of significance tests” (p. 57). Tests of model assumptions, also called misspecification (M-S) tests, are thus a promising area for Bayes-frequentist collaboration. (4.9) When the model is in doubt, the likelihood principle is inapplicable or violated. We illustrate a non-parametric bootstrap resampling. It works without relying on a theoretical probability distribution, but it still has assumptions. (4.10). We turn to the M-S testing approach of econometrician Aris Spanos.(4.11) I present the high points for unearthing spurious correlations, and assumptions of linear regression, employing 7 figures. M-S tests differ importantly from model selection–the latter uses a criterion for choosing among models, but does not test their statistical assumptions. They test fit rather than whether a model has captured the systematic information in the data.

1. Michael Naaman
It was proved in “almost sure hypothesis testing and a resolution of the Jeffreys-Lindley paradox” that the paradox is a result of keeping the significance level fixed. If the significance level decreases at a sufficiently fast rate the paradox disappears. Almost sure hypothesis testing resolves most of the complaints about null hypothesis testing.
• Sure, but there’s no paradox if you take account of sample size, as the P-value does. The business of P-values exaggerating is a bit different. Here it’s a matter of comparing the P-value to a very different measure, such as a Bayes factor or posterior probability in a hypothesis.

5.7.2. Persistent Changes: semanage fcontext
The /usr/sbin/semanage fcontext command changes the SELinux context for files. When using targeted policy, changes made with this command are added to the /etc/selinux/targeted/contexts/files/file_contexts file if the changes are to files that exists in file_contexts, or are added to file_contexts.local for new files and directories, such as creating a /web/ directory. setfiles, which is used when a file system is relabeled, and /sbin/restorecon, which restores the default SELinux contexts, read these files. This means that changes made by /usr/sbin/semanage fcontext are persistent, even if the file system is relabeled. SELinux policy controls whether users are able to modify the SELinux context for any given file.
Quick Reference
To make SELinux context changes that survive a file system relabel:
1. Run the /usr/sbin/semanage fcontext -a options file-name|directory-name command, remembering to use the full path to the file or directory.
2. Run the /sbin/restorecon -v file-name|directory-name command to apply the context changes.
Changing a File's Type
The following example demonstrates changing a file's type, and no other attributes of the SELinux context:
1. As the Linux root user, run the touch /etc/file1 command to create a new file. By default, newly-created files in the /etc/ directory are labeled with the etc_t type:
# ls -Z /etc/file1
-rw-r--r-- root root unconfined_u:object_r:etc_t:s0 /etc/file1
2. As the Linux root user, run the /usr/sbin/semanage fcontext -a -t samba_share_t /etc/file1 command to change the file1 type to samba_share_t. The -a option adds a new record, and the -t option defines a type (samba_share_t). Note: running this command does not directly change the type - file1 is still labeled with the etc_t type:
# /usr/sbin/semanage fcontext -a -t samba_share_t /etc/file1
# ls -Z /etc/file1
-rw-r--r-- root root unconfined_u:object_r:etc_t:s0 /etc/file1
The /usr/sbin/semanage fcontext -a -t samba_share_t /etc/file1 command adds the following entry to /etc/selinux/targeted/contexts/files/file_contexts.local:
/etc/file1 unconfined_u:object_r:samba_share_t:s0
3. As the Linux root user, run the /sbin/restorecon -v /etc/file1 command to change the type. Since the semanage command added an entry to file.contexts.local for /etc/file1, the /sbin/restorecon command changes the type to samba_share_t:
# /sbin/restorecon -v /etc/file1
restorecon reset /etc/file1 context unconfined_u:object_r:etc_t:s0->system_u:object_r:samba_share_t:s0
4. As the Linux root user, run the rm -i /etc/file1 command to remove file1.
5. As the Linux root user, run the /usr/sbin/semanage fcontext -d /etc/file1 command to remove the context added for /etc/file1. When the context is removed, running restorecon changes the type to etc_t, rather than samba_share_t.
Changing a Directory's Type
The following example demonstrates creating a new directory and changing that directory's file type, to a type used by Apache HTTP Server:
1. As the Linux root user, run the mkdir /web command to create a new directory. This directory is labeled with the default_t type:
# ls -dZ /web
drwxr-xr-x root root unconfined_u:object_r:default_t:s0 /web
The ls -d option makes ls list information about a directory, rather than its contents, and the -Z option makes ls display the SELinux context (in this example, unconfined_u:object_r:default_t:s0).
2. As the Linux root user, run the /usr/sbin/semanage fcontext -a -t httpd_sys_content_t /web command to change the /web/ type to httpd_sys_content_t. The -a option adds a new record, and the -t option defines a type (httpd_sys_content_t). Note: running this command does not directly change the type - /web/ is still labeled with the default_t type:
# /usr/sbin/semanage fcontext -a -t httpd_sys_content_t /web
# ls -dZ /web
drwxr-xr-x root root unconfined_u:object_r:default_t:s0 /web
The /usr/sbin/semanage fcontext -a -t httpd_sys_content_t /web command adds the following entry to /etc/selinux/targeted/contexts/files/file_contexts.local:
/web unconfined_u:object_r:httpd_sys_content_t:s0
3. As the Linux root user, run the /sbin/restorecon -v /web command to change the type. Since the semanage command added an entry to file.contexts.local for /web, the /sbin/restorecon command changes the type to httpd_sys_content_t:
# /sbin/restorecon -v /web
restorecon reset /web context unconfined_u:object_r:default_t:s0->system_u:object_r:httpd_sys_content_t:s0
By default, newly-created files and directories inherit the SELinux type of their parent folders. When using this example, and before removing the SELinux context added for /web/, files and directories created in the /web/ directory are labeled with the httpd_sys_content_t type.
4. As the Linux root user, run the /usr/sbin/semanage fcontext -d /web command to remove the context added for /web/.
5. As the Linux root user, run the /sbin/restorecon -v /web command to restore the default SELinux context.
Changing a Directory and its Contents Types
The following example demonstrates creating a new directory, and changing the directory's file type (along with its contents) to a type used by Apache HTTP Server. The configuration in this example is used if you want Apache HTTP Server to use a different document root (instead of /var/www/html/):
1. As the Linux root user, run the mkdir /web command to create a new directory, and then the touch /web/file{1,2,3} command to create 3 empty files (file1, file2, and file3). The /web/ directory and files in it are labeled with the default_t type:
# ls -dZ /web
drwxr-xr-x root root unconfined_u:object_r:default_t:s0 /web
# ls -lZ /web
-rw-r--r-- root root unconfined_u:object_r:default_t:s0 file1
-rw-r--r-- root root unconfined_u:object_r:default_t:s0 file2
-rw-r--r-- root root unconfined_u:object_r:default_t:s0 file3
2. As the Linux root user, run the /usr/sbin/semanage fcontext -a -t httpd_sys_content_t "/web(/.*)?" command to change the type of the /web/ directory and the files in it, to httpd_sys_content_t. The -a option adds a new record, and the -t option defines a type (httpd_sys_content_t). The "/web(/.*)?" regular expression causes the semanage command to apply changes to the /web/ directory, as well as the files in it. Note: running this command does not directly change the type - /web/ and files in it are still labeled with the default_t type:
# ls -dZ /web
drwxr-xr-x root root unconfined_u:object_r:default_t:s0 /web
# ls -lZ /web
-rw-r--r-- root root unconfined_u:object_r:default_t:s0 file1
-rw-r--r-- root root unconfined_u:object_r:default_t:s0 file2
-rw-r--r-- root root unconfined_u:object_r:default_t:s0 file3
The /usr/sbin/semanage fcontext -a -t httpd_sys_content_t "/web(/.*)?" command adds the following entry to /etc/selinux/targeted/contexts/files/file_contexts.local:
/web(/.*)? system_u:object_r:httpd_sys_content_t:s0
3. As the Linux root user, run the /sbin/restorecon -R -v /web command to change the type of the /web/ directory, as well as all files in it. The -R is for recursive, which means all files and directories under the /web/ directory are labeled with the httpd_sys_content_t type. Since the semanage command added an entry to file.contexts.local for /web(/.*)?, the /sbin/restorecon command changes the types to httpd_sys_content_t:
# /sbin/restorecon -R -v /web
restorecon reset /web context unconfined_u:object_r:default_t:s0->system_u:object_r:httpd_sys_content_t:s0
restorecon reset /web/file2 context unconfined_u:object_r:default_t:s0->system_u:object_r:httpd_sys_content_t:s0
restorecon reset /web/file3 context unconfined_u:object_r:default_t:s0->system_u:object_r:httpd_sys_content_t:s0
restorecon reset /web/file1 context unconfined_u:object_r:default_t:s0->system_u:object_r:httpd_sys_content_t:s0
By default, newly-created files and directories inherit the SELinux type of their parents. In this example, files and directories created in the /web/ directory will be labeled with the httpd_sys_content_t type.
4. As the Linux root user, run the /usr/sbin/semanage fcontext -d "/web(/.*)?" command to remove the context added for "/web(/.*)?".
5. As the Linux root user, run the /sbin/restorecon -R -v /web command to restore the default SELinux contexts.
Deleting an added Context
The following example demonstrates adding and removing an SELinux context:
1. As the Linux root user, run the /usr/sbin/semanage fcontext -a -t httpd_sys_content_t /test command. The /test/ directory does not have to exist. This command adds the following context to /etc/selinux/targeted/contexts/files/file_contexts.local:
/test system_u:object_r:httpd_sys_content_t:s0
2. To remove the context, as the Linux root user, run the /usr/sbin/semanage fcontext -d file-name|directory-name command, where file-name|directory-name is the first part in file_contexts.local. The following is an example of a context in file_contexts.local:
/test system_u:object_r:httpd_sys_content_t:s0
With the first part being /test. To prevent the /test/ directory from being labeled with the httpd_sys_content_t after running /sbin/restorecon, or after a file system relabel, run the following command as the Linux root user to delete the context from file_contexts.local:
/usr/sbin/semanage fcontext -d /test
If the context is part of a regular expression, for example, /web(/.*)?, use quotation marks around the regular expression:
/usr/sbin/semanage fcontext -d "/web(/.*)?"
Refer to the semanage(8) manual page for further information about /usr/sbin/semanage.
Important
When changing the SELinux context with /usr/sbin/semanage fcontext -a, use the full path to the file or directory to avoid files being mislabeled after a file system relabel, or after the /sbin/restorecon command is run.

Tukey's range test
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Tukey's range test, also known as the Tukey's test, Tukey method, Tukey's honest significance test, Tukey's HSD (honest significant difference) test,[1] or the Tukey–Kramer method, is a single-step multiple comparison procedure and statistical test. It can be used on raw data or in conjunction with an ANOVA (Post-hoc analysis) to find means that are significantly different from each other . Named after John Tukey,[2] it compares all possible pairs of means, and is based on a studentized range distribution (q) (this distribution is similar to the distribution of t from the t-test).[3] The Tukey HSD tests should not be confused with the Tukey Mean Difference tests (also known as the Bland–Altman test).
Tukey's test compares the means of every treatment to the means of every other treatment; that is, it applies simultaneously to the set of all pairwise comparisons
\mu_i-\mu_j \,
and identifies any difference between two means that is greater than the expected standard error. The confidence coefficient for the set, when all sample sizes are equal, is exactly 1 − α. For unequal sample sizes, the confidence coefficient is greater than 1 − α. In other words, the Tukey method is conservative when there are unequal sample sizes.
Assumptions of Tukey's test[edit]
1. The observations being tested are independent within and among the groups.
2. The groups associated with each mean in the test are normally distributed.
3. There is equal within-group variance across the groups associated with each mean in the test (homogeneity of variance).
The test statistic[edit]
Tukey's test is based on a formula very similar to that of the t-test. In fact, Tukey's test is essentially a t-test, except that it corrects for experiment-wise error rate (when there are multiple comparisons being made, the probability of making a type I error increases — Tukey's test corrects for that, and is thus more suitable for multiple comparisons than doing a number of t-tests would be).[3]
The formula for Tukey's test is:
q_s = \frac{Y_A - Y_B}{SE},
where YA is the larger of the two means being compared, YB is the smaller of the two means being compared, and SE is the standard error of the data in question.
This qs value can then be compared to a q value from the studentized range distribution. If the qs value is larger than the qcritical value obtained from the distribution, the two means are said to be significantly different.[3]
Since the null hypothesis for Tukey's test states that all means being compared are from the same population (i.e. μ1 = μ2 = μ3 = ... = μn), the means should be normally distributed (according to the central limit theorem). This gives rise to the normality assumption of Tukey's test.
The studentized range (q) distribution[edit]
The Tukey method uses the studentized range distribution. Suppose that we take a sample of size n from each of k populations with the same normal distribution N(μ, σ) and suppose that \bar{y}min is the smallest of these sample means and \bar{y}max is the largest of these sample means, and suppose S2 is the pooled sample variance from these samples. Then the following random variable has a Studentized range distribution.
q = \frac{(\overline{y}_{max} - \overline{y}_{min})}{S\sqrt{2/n}}
This value of q is the basis of the critical value of q, based on three factors:
1. α (the Type I error rate, or the probability of rejecting a true null hypothesis)
2. k (the number of populations)
3. df (the number of degrees of freedom (N-k) where N is the total number of observations)
The distribution of q has been tabulated and appears in many textbooks on statistics and online. In some tables the distribution of q has been tabulated without the \sqrt{2} factor. To understand which table it is, we can compute the result for k=2 and compare it to the result of the Student's t-distribution with the same degrees of freedom and the same α. In addition, R offers a cumulative distribution function (ptukey) and a quantile function (qtukey) for q.
Confidence limits[edit]
The Tukey confidence limits for all pairwise comparisons with confidence coefficient of at least 1 − α are
\bar{y}_{i\bullet}-\bar{y}_{j\bullet} \pm \frac{q_{\alpha;k;N-k}}{\sqrt{2}}\widehat{\sigma}_\varepsilon \sqrt{\frac{2}{n}} \qquad i,j=1,\ldots,k\quad i\neq j.
Notice that the point estimator and the estimated variance are the same as those for a single pairwise comparison. The only difference between the confidence limits for simultaneous comparisons and those for a single comparison is the multiple of the estimated standard deviation.
Also note that the sample sizes must be equal when using the studentized range approach. \widehat{\sigma}_\varepsilon is the standard deviation of the entire design, not just that of the two groups being compared. It is possible to work with unequal sample sizes. In this case, one has to calculate the estimated standard deviation for each pairwise comparison as formalized by Clyde Kramer in 1956, so the procedure for unequal sample sizes is sometimes referred to as the 'Tukey–Kramer method which is as follows:
\bar{y}_{i\bullet}-\bar{y}_{j\bullet} \pm \frac{q_{\alpha;k;N-k}}{\sqrt{2}}\widehat{\sigma}_\varepsilon \sqrt{\frac{1}{n}_{i} + \frac{1}{n}_{j}} \qquad
where n i and n j are the sizes of groups i and j respectively. The degrees of freedom for the whole design is also applied.
Advantages and disadvantages[edit]
When doing all pairwise comparisons, this method is considered the best available when confidence intervals are needed or sample sizes are not equal. When samples sizes are equal and confidence intervals are not needed Tukey’s test is slightly less powerful than the stepdown procedures, but if they are not available Tukey’s is the next-best choice, and unless the number of groups is large, the loss in power will be slight. In the general case when many or all contrasts might be of interest, Scheffé's method tends to give narrower confidence limits and is therefore the preferred method.

What is Multimedia?
Multimedia is a broad term that encompasses making, storing, retrieving, transferring, and presenting various types of information, such as text, graphics, pictures, videos, and sound. Multimedia involves a complex weave of communications, electronics, and computer technologies. It is beyond the scope of this book to cover multimedia in great detail. This chapter concentrates on the presentation of multimedia in Java.
Whereas most programming languages have no built-in multimedia capabilities, Java was designed with multimedia in mind. It provides extensive built-in support that makes it easy to develop powerful multimedia applications. Java's multimedia capabilities include animation that uses drawings, audio, and images.

The URL Class
Audio and images are stored in files. The java.net.URL class can be used to identify the files on the Internet. In general, a URL (Uniform Resource Locator) is a pointer to a "resource" on the World Wide Web. A resource can be something as simple as a file or a directory. You can create a URL object using the following constructor:
public URL(String spec) throws MalformedURLException
For example, the following statement creates a URL object for http://www.sun.com:
try {
URL url = new URL("http://www.sun.com");
}
catch(MalformedURLException ex) {
}
Creating a URL for Local Files
The following statement creates a URL object for the file c:\book\image\us.gif.
try {
URL url = new URL("c:\\book\\image\\us.gif");
}
catch(MalformedURLException ex) {
}
The preceding statement creates a URL for the absolute file name c:\book\beep.au on the Windows. There are two problems: (1) the file location is fixed; (2) it is platform-dependent. To circumvent these problems, you can create the URLs for files using through the resource of the class file using the java.lang.Class class.
Creating a URL from a Class Reference
Whenever the Java Virtual Machine loads a class or an interface, it creates an instance of a special class named Class. The Class class provides access to useful information about the class, such as the data fields and methods. It also contains the getResource(filename) method, which can be used to obtain the URL of a given file name in the same directory with the class or in its subdirectory. As discussed in Section 8.4.5, “The getClass Method,” you can obtain the class for the object at runtime. Thus, you can use the following code to get the URL of a file:
Class class = this.getClass();
URL url = class.getResource(filename);
where filename is a relative file name in the same directory or a subdirectory of the class. Suppose you run a class stored in c:\book, the following statement creates a URL object for c:\book\image\us.gif.
URL url = this.getClass().getResource(“image\us.gif");
Creating ImageIcon Using Absolute File Names
You used the ImageIcon class to create an icon from an image file and the setIcon method or the constructor to place the image in a GUI component, such as a button and a label. For example, the following statements create an ImageIcon and set it on an JLabel object jlbl.
ImageIcon imageIcon = new ImageIcon("c:\\book\\image\\us.gif");
//ImageIcon imageIcon = new ImageIcon("image/us.gif");
jlbl.setIcon(imageIcon);
This approach suffers a problem. The file location is fixed since it uses the absolute file path on Window. Thus, the program cannot run on other platforms and cannot run as applet.
Creating ImageIcon Using Class Reference
To circumvent this problem, you can create the URLs for files through the class reference using the java.lang.Class class. For example, suppose the class file is in c:\book, the following statements create a URL for c:\book\image\us.gif.
Class class = this.getClass();
URL url = class.getResource("image/us.gif");
You can now create an ImageIcon using
ImageIcon imageIcon = new ImageIcon(url);
Creating Image From ImageIcon
An image icon displays a fixed-size image. To display an image in a flexible size, you need to use the java.awt.Image class. An image can be created from an image icon as follows:
Image image = imageIcon.getImage();
Given an Image, you can create an ImageIcon using
ImageIcon imageIcon = new ImageIcon(image);
Drawing Images in Graphics
Using a label as an area for displaying images is simple and convenient, but you don't have much control over how the image is displayed. A more flexible way to display images is to use the drawImage method of the Graphics class on a panel using one of the foure overloaded drawImage method.
drawImage(Image img, int x, int y, Color bgcolor, ImageObserver observer)
drawImage(Image img, int x, int y, ImageObserver observer)
drawImage(Image img, int x, int y, ImageObserver observer)
drawImage(Image img, int x, int y, int width, int height, Color bgcolor, ImageObserver observer)
ImageObserver is an asynchronous update interface that receives notifications of image information as the image is constructed. The Component class implements ImageObserver. Therefore, every GUI component is an instance of ImageObserver. To draw images using the drawImage method in a Swing component, such as JPanel, override the paintComponent method to tell the component how to display the image in the panel.
Displaying Image
Write a program that displays an image from /image/us.gif in the class directory on a panel.

Creating AudioClip from an Audio File
To play an audio file in an applet, first create an audio clip object for the audio file. The audio clip is created once and can be played repeatedly without reloading the file. To create an audio clip, use the static method newAudioClip() in the java.applet.Applet class:
AudioClip audioClip = Applet.newAudioClip(url);
Audio was originally used with Java applets. For this reason, the AudioClip interface is in the java.applet package.
The following statements, for example, create an AudioClip for the beep.au audio file in the same directory with the class you are running.
Class class = this.getClass();
URL url = class.getResource("beep.au");
AudioClip audioClip = Applet.newAudioClip(url);
Playing Audio
To manipulate a sound for an audio clip, use the play(), loop(), and stop() methods in java.applet.AudioClip.
Playing Anthem Example
Objective: Display images and playing audio in applets and in applications.

Run as an Application
Optional
Packaging and Deploying Java Projects
What is JAR?
Java archive file can be used to group all the project files in a compressed file for deployment.
The Java archive file format (JAR) is based on the popular ZIP file format.
This single file can be deployed on an end-user’s machine as an application. It also can be downloaded to a browser in a single HTTP transaction, rather than opening a new connection for each piece. This greatly simplifies application deployment and improves the speed with which an applet can be loaded onto a web page and begin functioning.
Creating JAR
You can use the JDK jar command to create an archive file. The following command creates an archive file named TicTacToe.jar for classes TicTacToe.class and TicTacToe$Cell.class.
jar -cf TicTacToe.jar TicTacToe.class TicTacToe$Cell.class
The -c option is for creating a new archive file, and the -f option specifies the archive file’s name.
Viewing the Contents of a JAR File
You can view the contents of a .jar file using WinZip.
Manifest File
A manifest file was created with the path name meta-inf\. The manifest is a special file that contains information about the files packaged in a JAR file. For instance, the manifest file in TicTacToe.jar contains the following information:
Manifest-Version: 1.0
Name: TicTacToe.class
Java-Bean: True
Name: TioTacToe$Cell.class
Java-Bean: True
You can modify the information contained in the manifest file to enable the JAR file to be used for a variety of purposes. For instance, you can add information to specify a main class to run an application using the .jar file.
Running Archived Projects Standalone
The manifest file must have an entry to contain the main class. For example, to run TicTacToe, you need to insert the following two lines in the manifest file:
Main-Class: TicTacToe
Sealed: true
Run the .jar file using the java command from the directory that contains TicTacToe.jar,
java -jar TicTacToe.jar
TIP: You can write an installation procedure that creates the necessary directories and subdirectories on the end-user’s computer. The installation can also create an icon that the end-user can double-click on to start the program. For information on creating Windows desktop icon, please see www.prenhall.com/liang/intro5e.html.
Running Archived Projects As Applet
To run TicTacToe as an applet, modify the <APPLET> tag in the HTML file to include an ARCHIVE attribute. The ARCHIVE attribute specifies the archive file in which the applet is contained. For example, the HTML file for running TicTacToe can be modified as shown below:
<APPLET
CODE = "TicTacToe.class"
ARCHIVE = "TicTacToe.jar"
WIDTH = 400
HEIGHT = 300
HSPACE = 0
VSPACE = 0
ALIGN = Middle
>
</APPLET>
Optional
Pluggable Look-and-Feel
The pluggable look-and-feel feature lets you design a single set of GUI components that automatically has the look-and-feel of any OS platform. The implementation of this feature is independent of the underlying native GUI, yet it can imitate the native behavior of the native GUI.
Currently, Java supports the following three look-and-feel styles:
· Metal
· Motif
· Windows
Setting Look-And-Feel
The javax.swing.UIManager class manages the look-and-feel of the user interface. You can use one of the following three methods to set the look-and-feel for Metal, Motif, or Windows:
UIManager.setLookAndFeel
(UIManager.getCrossPlatformLookAndFeelClassName());
UIManager.setLookAndFeel
(new com.sun.java.swing.plaf.motif.MotifLookAndFeel());
UIManager.setLookAndFeel
(new com.sun.java.swing.plaf.windows.WindowsLookAndFeel());
Setting Look-And-Feel in Static Initialization Block
To ensure that the setting takes effect, the setLookAndFeel method should be executed before any of the components are instantiated. Thus, you can put the code in a static block, as shown below:
static {
try {
// Set a look-and-feel, e.g.,
//UIManager.setLookAndFeel
// (UIManager.getCrossPlatformLookAndFeelClassName());
}
catch (UnsupportedLookAndFeelException ex) {}
}
Static initialization blocks are executed when the class is loaded. For more information on static initialization blocks, please refer to Section 8.12, “Initialization Block.”

Autoclustering PostgreSQL dengan Replikasi Primary-Secondary Asynchronous
Data merupakan sebuah kompoenen penting bagi operasional sebuah aplikasi. Maka dari itu, data harus dapat berubah sesuai dengan lingkungan aplikasi yang dinamis.
Dalam keamanan siber, menyimpan data di satu lokasi yang sama artinya dengan meningkatkan risiko kerusakan data ketika terjadi kegagalan sistem.
Untuk menghindari hal tersebut, kamu perlu membuat strategi untuk memastikan data kamu selalu tersedia (high-availability). Salah satu solusi terbaik untuk memastikan high-availability adalah menyimpan data di beberapa server yang disinkronkan.
Menyimpan data di beberapa database akan mengurangi kemungkinan kegagalan sistem, meningkatkan produktivitas, mempermudah proses backup, dan meningkatkan kinerja analisa data.
Di antara banyaknya solusi clustering database, Dewacloud menyediakan PostgreSQL dengan replikasi primary-secondary secara asinkron. Secara default, Dewacloud akan men-deploy dua container database (primary & secondary).
Server master akan berperan sebagai instance aktif dan menerima operasi read-write. Sedangkan server slave akan menjalankan salinan server master dan menangani operasi read-only. Karena itu, jika database utama mengalami kegagalan karena kesalahan di container atau database yang corrupt, server slave harus menggantikan perannya agar database tetap tersedia.
alur replikasi postgresql
Dalam topology cluster, setiap container database memiliki vertical scaling default mulai dari 2 reserved cludlet hingga 32 dynamic cloudlet (hingga 4 GiB RAM & 12,8 GHz CPU).
Resource tersebut dialokasikan secara dinamis berdasarkan load yang masuk. Selanjutnya, kamu dapat mengubah batas alokasi resource dengan mengikuti panduan yang ditautkan sebelumnya.
Database Cluster akan terinstal secara otomatis:
• Sebagai aplikasi Marketplace
• Melalui fitur Auto-Clustering yang tertanam di Dashboard
Instalasi PostgreSQL Melalui Marketplace Dewacloud
Kamu dapat menginstal dan deploy PostgreSQL Primary-Secondary Cluster dari marketplace Dewacloud.
marketplace postgresql master-slav
Jika diperlukan, kamu dapat mengubah versi database, nama environment, dan pilihan region di jendela Topology Wizard.
instalasi postgresql dewacloud
Mode Auto-Clustering PostgreSQL
Di Dewacloud, kamu dapat mengaktifkan auto-clustering dalam beberapa menit saja. Untuk mengaktifkan auto-clustering, kamu dapat membuka topology wizard di dashboard, memilih software stack (misalnya PostgreSQL 12.3), dan mengaktifkan fitur Auto-Clustering.
Jika diperlukan, kamu juga dapat mengubah region untuk men-deploy database kamu. Saat penulisan artikel ini, Dewacloud memiliki region di Jakarta dan Singapura.
Tip: Resource package Replikasi PostgreSQL tersedia dalam Dewacloud JPS Collection bersama dengan solusi berguna lainnya, salah satu yang dapat diintegrasikan melalui import file manifest.yaml atau manifest.jps dari repository yang sesuai.
Cluster Topology
Topologi cluster database yang diperoleh pada kedua deployment akan terlihat seperti berikut ini:
topologi baru postgresql
Ketika instalasi cluster database selesai, kamu akan melihat pesan konfirmasi dengan URL node master dan kredensial untuk akses database. Semua informasi ini diduplikasi melalui email.
Catatan: Jika cluster di instal dengan fungsi auto-clustering, kredensial hanya dikirim melalui email.
Sekarang, mari kita menempatkan database master ke dalam tindakan untuk memeriksa bahwa data berhasil direplikasi ke slave.
Menguji Replikasi Database PostgreSQL
Untuk memastikan bahwa data direplikasi dengan benar, kami akan membuat instance DB baru di mater container dan memeriksa keberadaannya di dalam secondary.
Buat Database Baru
1. Klik tombol Open in Browser yang ada di samping node primary PostgreSQL untuk membuka phpPgAdmin.
open in browser primary node
2. Di bawah Server, klik PostgreSQL dan masuk dengan kredensial yang kamu peroleh di email setelah pembuatan cluster.
phpPgAdmin
3. Klik Create Database untuk mulai membuat database baru.
4. Isi Name di dalam box (contohnya Dewacloud), dan klik Create.
create database
Setelah berhasil membuat database di primary node, kamu perlu memastikan bahwa replikasi berjalan dengan lancar di secondary node.
Periksa Hasil Replikasi Database
Ikutit langkah-langkah berikut ini untuk memastikan bahwa replikasi data dari primary node ke secondary node berjalan dengan baik:
1. Klik Open in Browser di samping node PostgreSQL Slave untuk membuka interface yaitu web phpPgAdmin.
open in browser secondary node
2. Akses interface admin dengan username dan password yang sama untuk digunakan dalam mengakses master node.
3. Setelah masuk, kamu dapat melihat database yang direplikasi (di contoh ini, Dewacloud).
secondary database
4. Penutup
Itu saja! Environment PostgreSQL dengan replikasi primary-secondary secara asinkron sudah dapat mulai memproses data.
Sebagai langkah selanjutnya, kamu dapat menghubungkan database yang direplikasi PostgreSQL ini ke project kamu. Prosesnya tergantung pada aplikasi yang spesifik, jika ikuti petunjuk di bawah ini:
Penutup
Sangat mudah, bukan?
Sekarang kamu tak perlu repot-repot mengonfigurasi database PostgreSQL primary-secondary. Cukup dengan satu klik saja, maka database kamu akan otomatis direplikasi oleh sistem Dewacloud.
Coba Dewacloud sekarang juga untuk mendapatkan hosting database yang jauh lebih terjangkau daripada solusi lainnya.

Display Horizontal Bar Chart
RadChart allows a series to be rendered vertically as well as horizontally. A series position depends on the axes that you define. Thus in order to display a bar series horizontally, you need to define the category axis as a vertical axis, rather than a horizontal axis. Define a Bar Chart with a Horizontal Series
The following example demonstrates how to create a RadCartesianChart with horizontal BarSeries.Chart-How To-Horizontal Bar Chart
Create a bar chart with swapped axes.
<telerik:RadCartesianChart>

Blogger custom domain confusions - Check before you buy
In the Blogger community forum, I happened to help a user who was not able to publish their blogspot address to their custom domain. After doing all the debugging, there was no option left out but to contact Google and finally we have known what the problem is.
The problem was that the URL was not available for use in blogger.
Here on, before spending money on buying a domain, please ensure blogger allows it.
Why isn't the custom domain available to buy but not available to use on Blogger?
That'd be the first question every user would ask or think to ask. Unfortunately reason is un-disclosed by Blogger themselves.
So how do we know if a domain is available at Blogger or not?
Earlier, there used to be no way we could do this as Blogger would throw a more generic error like below,
Now, we get a more customised error for this particular case alone like below,
So, here on, before spending money on buying a domain, please try publishing your blog in the domain name you are planning to buy so that you can know for sure Blogger allows it.

So, once upon a time, a really long while ago, I tried to customise and recreate a Blogger template which is not available anymore, but there's one thing I remember about it.

Blogger HTTPS for custom domain and Cloudflare
In BHF, there was a recent issue related to cloudflare where the browser screams the site is a phishing site. So I thought of writing up how does a service like cloudflare affect your blogger blog. What is Cloudflare? Well we have that written all over Wikipedia: Cloudflare . Let's go on with why Blogger users look for Cloudflare. Anciently Blogger users used Cloudflare for one simple reason. HTTPS for custom domains. So what happens when you introduce Cloudflare into your domain? DNS Redirect. Your custom domain will be configured with the proxy info provided by Cloudflare and when the request is hit, DNS redirect happens. DNS redirect is bad for the site's health. A number of reasons, but the most important is that some browsers, when it detects a DNS redirection, it thinks that it is a phishing site. What is a DNS redirect? I am trying to explain this in easy terms. I'll try not to be too technical. When a custom domain URL is hit, usually the domain reques

In this case, the portable terminal equipment of the user and the center can give and receive information or signal by wireless communication. As such communication system, cellular system in portable telephone or PHS (personal handyphone system) may be used. As the portable terminal equipment of the user, an equipment comprising CPU (central processing unit), memory, interface, cursor key, etc. further provided with a display unit having graphic display function may be used. Also, by adding a touch panel on the display unit, the desired instruction can be inputted when the user simply touches an arrow or other icons in a map displayed on the display unit.
To make the system of the present invention usable in an area of wide range, a cellular system is used as described above. If it is supposed that PHS is used, the present position of PHS terminal (slave set) is registered at a wireless base station (master set of the cell), and communication with the center can be performed through the wireless base station. When the user is walking and goes out of the registered cell and enters the next cell, the position is registered at the wireless base station of that cell. For the wireless access system, 4-channel multiplex TDMA-TDD (Time Division Multiple Access-Time Division Duplex) can be used.
In the description given below, it is supposed that the terminal equipment on the user side has the function of the pedestrian information processing unit 11, and the function of the pedestrian information processing unit 11 will be explained here.
The pedestrian information processing unit 11 comprises an input/output control means 11 for receiving input from the user, a pedestrian map data generating and editing means 115 for generating and editing the pedestrian map data 13 (In case the pedestrian information processing unit 11 is at the terminal equipment on the user side, the pedestrian map data generating and editing means 115 is arranged on the center side.), a pedestrian map data searching means 114 for searching a map data in the corresponding area from the pedestrian map data 13, a pedestrian route searching means 112 for searching a route for pedestrians using the searched pedestrian map data 13, a scheduling means 113 for setting up a plan to make an inspection tour for a plurality of destinations according to a schedule determined in advance, a time simulation means 116 for simulating a time of arrival at the destination, and a transportation determining means 117 for selecting a transportation means, by which the destination can be reached at an earliest chance.
As shown in FIG. 2, the pedestrian route searching means 112 comprises a route searching means 1122 for searching a route between two points, i.e. departure point and destination, a route searching means 1121 for searching a route connecting a plurality of geographical points in case there are two or more destinations, a route searching means 1123 for searching a route in case two or more transportation means are used, and an attribute determining means 1124 for determining attributes of a route, which should be considered in selecting a route.
As shown in FIG. 3, the pedestrian map data searching means 114 comprises an address corresponding data searching means for searching a block corresponding to the inputted address, a latitude/longitude corresponding data searching means 1145 for searching a block to correspond to the inputted latitude/longitude, a name corresponding data searching means 1146 for searching a block to correspond to the inputted name, a town information searching means 1147 for searching an object, a corresponding data searching means 1141 for searching by starting the address corresponding data searching means 1144, the latitude/longitude corresponding data searching means 1145 or the name corresponding data searching means 1146 in response to the inputted data, a town information searching means 1147 for searching an object from a town table where town information is recorded, and a nearest information searching means 1142 for searching a desired town information using the two information searching means 1147 while extending the area to be searched to adjacent area.
Next, description will be given on a pedestrian map specially prepared for pedestrians. The area of the pedestrian map as shown by the pedestrian map data 13 is divided to an area (non-pedestrian area) such as road with heavy traffic, expressway, railway, rivers and canals, etc. where pedestrians cannot walk safely, and an area (pedestrian area) bordered and defined by the non-pedestrian area and where pedestrians can walk safely.
Each of the non-pedestrian area and the pedestrian area comprises streets where pedestrian can walk and blocks where pedestrians cannot pass freely. In the non-pedestrian area (e.g. on a road with heavy traffic), footbridge or pedestrians' crossing is considered as a street, and the other portions of the road are considered as blocks. In case of rivers and canals, bridges are considered as streets. In railroad, railroad crossings and subterranean walks are considered as streets. In the pedestrian area, road where pedestrians can walk are considered as streets, and houses, buildings and unoccupied and reserved grounds are considered as blocks.
In the non-pedestrian area, areas where pedestrians cannot walk freely due to steps (with different height) or difference in management are included. In case of the steps, stairways, elevators, escalators, etc. are considered as streets. In the non-pedestrian area where pedestrians cannot walk freely due to difference in management body, wickets or toll gates are considered as streets.
In case a block in the pedestrian area is a large building, there are non-pedestrian area and pedestrian area inside this building. Each floor of this building is a pedestrian area, portions other than floors are non-pedestrian areas, and an elevator connecting the floors is considered as a street in the non-pedestrian area.
FIG. 4 is a correspondence table of blocks and streets in the pedestrian area and the non-pedestrian area. The pedestrian area and the non-pedestrian area are the same in structure while they are different from each other in the contents of objects. FIG. 5 summarizes classification of streets in each of the non-pedestrian area.
FIG. 6 shows basic arrangement of a pedestrian map. Area 1 (railroad 1), area 2 (road 1), area 3 (road 2), and area 4 (river 1) are non-pedestrian areas, and areas A to I are pedestrian areas. Footbridge, pedestrians' crossing, bridge, and overpass are streets in the non-pedestrian area.
FIGS. 7A and 7B show an arrangement in an area. FIG. 7A shows details of a pedestrian area I, and FIG. 7B shows details of a non-pedestrian area 3. The pedestrian area I comprises blocks 1 to 9 and 6 streets, and blocks can be classified to blocks having an arrangement of an area such as building, and blocks having no arrangement of an area such as unoccupied ground.
FIG. 8 shows a block having an arrangement of an area (block 9 of FIG. 7A). In this example, each floor of the building is a pedestrian area, portions other than the floors are non-pedestrian areas, and an elevator connecting the floors is considered as a street in the non-pedestrian area. Thus, an area in the pedestrian map has a hierarchical structure.
In the pedestrian map data 13, area data relating to each area, block data relating to each block, and street data relating to each street are stored. As shown in FIG. 9, the area data include the following data: area attributes describing attributes such as area ID, area name, attributes such as street/floor/river, etc., a slave block describing blocks present in the area, a slave street describing streets present in an area, entrance and exit showing streets entering or outgoing from an area, an adjacent area describing adjacent area, a master block describing blocks present in an area in case the area belongs to a building, a map number, to which the area belongs, an administration region, to which the area belongs, and data such as polygonal information comprising the area.
As shown in FIG. 39A to FIG. 41B, block data include the following data: block ID, block name, master area, to which the block belongs, slave area in case the block includes the area, attributes of blocks to classify blocks such as buildings/parks, etc., connecting street, to which entrance and exit of the block are connected, map number where the block is present, coordinates of the block on map, address, to which the block belongs, polygonal information to form a block, and 3-dimensional data. In FIG. 39A to FIG. 41B, polygonal information and 3-dimensional information are not given.
As shown in FIG. 42A to FIG. 48B, the following data are included in the street data: street name, street ID, classification of street such as sidewalk/stairway/elevator/escalator, master area, to which the street belongs, map, to which the street belongs, address, to which the street belongs, adjacent block connected with the street, coordinates of starting point of the street, street connected to the starting point, coordinates of end point of the street, street connected to the end point, length of the street, etc. Further, the following data are included: attached facilities information such as street covering, street light/roadside trees/mail boxes/telephone poles/public telephones/automatic vending machines/bus stops/manholes/hydrants/fire extinguishers/water pipes/garbage dumps/guide plates for blind, etc., sidewalk road surface information such as walking distance/height difference/road surface condition, etc., and time-related information such as traffic condition/vehicle traffic/traffic congestion information/sunny place information, etc.
In the conventional road data, road is included in link data, and intersection is included in node data, and the data has a structure of ineffective graph. In the pedestrian information providing system of the present invention, it is considered that intersection does not have important information for pedestrians. Thus, the data for starting point and end point are provided to the data of street, which serves as a link, and these are arranged as effective graph. By the arrangement as described above, there is no need for each street to have node data divided, and the amount of data can be reduced.
As shown in FIG. 10, the following are stored in the storage unit of the pedestrian map data 13 to increase searching efficiency: a name index for searching the corresponding block from the name using a search tree (FIG. 11), an address index for searching block, area or street from the address using a search tree (FIG. 12), a map-area correspondence table describing map number of area including in a map with the number (FIG. 13), and a town table describing town information in each area (FIG. 14). Each of name index and address index has a pointer to the pedestrian map data, which serves as data of a terminal leaf, and it is arranged in such manner that the corresponding map data can be directly referred.
The map-area correspondence table (FIG. 13) is a reference table where map number calculated from latitude and longitude is matched to ID of the area included in the map. The town table (FIG. 14) is a correspondence table, which describes facilities and organizations included in each area (town information) and their block IDs classified for each area.
In the storage unit of the pedestrian map data 13, transportation means data describing lines and schedules of each transportation means are also stored.
Next, description will be given on operation in the pedestrian map data searching means 114 of the pedestrian information processing unit 11. As shown in FIG. 15, the corresponding data searching means 1141 of the pedestrian map data searching means 114 performs the following steps:
Step 1502: The type of the inputted data inputted from the input/output control means 111 is judged. If address is inputted;
Step 1503: The address corresponding data searching means 1144 is started to deliver the inputted address for searching.
In case latitude and longitude are inputted in Step 1502;
Step 1504: The latitude/longitude corresponding data searching means 1145 is started to deliver the inputted latitude and longitude for searching.
In case the name is inputted in Step 1502;
Step 1505: The name corresponding data searching means 1146 is started to deliver the inputted name for searching.
Step 1507: The data searched by each searching means are outputted to the input/output control means 11 or the pedestrian route searching means 112.
As shown FIG. 16, the address corresponding data searching means 114 as started performs the following steps:
Step 1103: The map data corresponding to the inputted address according to the address search tree of the address index (FIG. 12) is searched.
Step 1104: The data of searching result is sent back to the corresponding data searching means 1141.
As shown in FIG. 12, the address search tree comprises the following layers in this order: prefecture/municipalities/region name/street number/house number. The terminal leaf has a pointer to the component element of the pedestrian map data. If it is supposed that address data as shown in FIG. 17 is inputted, the address corresponding data searching means 1144 searches on the address search tree downward from the top as: Chiba Prefecture→Funabashi City→Honcho→6-chome→1→No. 50. Then, the map number 153 described on the leaf and block ID 1245 are outputted as the searching results.
When started, the latitude/longitude corresponding data searching means 1145 performs the following steps:
As shown in FIG. 18;
Step 1202: Map number including the inputted latitude and longitude is calculated.
Step 1203: The map-area correspondence table (FIG. 13) is referred to search an area including the inputted latitude and longitude using vertical line method from all areas included in the map. The vertical line method is a well-known method to check whether or not an arbitrary point is included in a predetermined region. In case a straight line starting from an arbitrary line crosses outer peripheral line of the region by odd number of times, that point is considered to be within the region. If it crosses by even number of times, the point is considered to be out of the region.
Step 1204: Area data in the searched area (FIG. 9) is referred to search a block including the inputted latitude and longitude by vertical line method from all blocks included in the area.
Steps 1205: Block data of the searched block is sent back to the corresponding data searching means 1141.
For example, when the data of FIG. 19 are inputted, the corresponding map number 5637-24-23 is calculated from the inputted latitude and longitude, and referring to the correspondence table of FIG. 13, area 2234 including the inputted latitude and longitude is searched from all areas included in the map with the map number 5637-24-23. Next, the area data of the area 2234 is referred, and a block including the inputted latitude and longitude is searched by vertical line method from all blocks included in the area. The data of the searched block b1248 (FIG. 20) is sent back to the corresponding data searching means 1141.
Also, as shown in FIG. 21, the name corresponding data searching means 1146 as started performs the following steps:
Step 1303: The map data corresponding to the inputted name is searched using the name search tree of the name index (FIG. 11).
Step 1304: The data of the searching results are sent back to the corresponding data searching means 1141.
As shown in FIG. 11, the name search tree has a tree structure similar to that of the address search tree, and each layer comprises a character from Japanese syllabary. The terminal leaf has a pointer to component element of the pedestrian map data as in case of the address search tree. For example, when a name data "Hachikou" is inputted as shown in FIG. 22, the name corresponding data searching means 1146 searches the name search tree of FIG. 11 downward from the top as "ha", "chi" "ko", and "u", and map 153 and block 1245 as described on the leaf are obtained. The block data of the block b1245 is sent back to the corresponding data searching means 1141.
The nearest information searching means 1142 of the pedestrian map data searching means 114 carries out the searching according to the procedure shown in FIG. 23 when an object to be searched is inputted from the input/output control means 111.
Step 2102: The object to be searched is inputted.
Step 2103: Address or latitude and longitude are inputted.
Step 2104: An area corresponding to the address or the latitude and the longitude are searched using the corresponding data searching means 1141. Based on the type of inputting, the corresponding data searching means 1141 searches the corresponding area by starting the address corresponding data searching means 1144 or the latitude/longitude corresponding data searching means 1145. The area data found in the result of the searching is sent to the nearest information searching means 1142.
Step 2105: The nearest information searching means 1142 searches the object to be searched from a town table of the searched area using the town information searching means 1147.
Step 2106: If the corresponding object is not found;
Step 2108: The data of adjacent area is found from the area data.
Step 2105: The object to be searched is searched from the town table of the adjacent area.
The procedure of Steps 2105, 2106 and 2108 is repeated, and when the corresponding object is found;
Step 2107: Data such as coordinates, address, etc. of all corresponding objects found are sent back to the requester of the searching.
For example, when a user wants to find out the nearest post office and inputs data to search the post office by specifying latitude and longitude of the present position, the latitude/longitude corresponding data searching means 1145 is started. An area 35a shown in FIG. 9 is searched, and the area data is sent to the nearest information searching means 1142.
The nearest information searching means 1142 searches the post office from the town table shown in FIG. 14 with "town-34" in the town information of the area 35a using the town information searching means 1147. Because data content of the corresponding object, i.e. post office, is null, similar searching is carried out for all adjacent areas of the area 35a and judges whether the corresponding object is present or not. The post office is found in the area 36a in this searching, and the data of the block 53, i.e. the corresponding object, is sent back.
By registering not only normal town information but also attribute on street in the town table, it is possible to carry out searching for wider range. For example, if positions of mailboxes are registered as attributes on street, the nearest mailbox can be searched.
Next, description will be given on operation in the pedestrian route searching means 112 of the pedestrian information processing unit 11. The attribute determining means 1124 of the pedestrian route searching means 112 determines attributes to be considered in selecting a route according to the procedure shown in FIG. 25. If data such as user category, departure point, destination, time, weather, and index in selecting a route (whether to select a route requiring the shortest time or a route with the shortest distance) are inputted from the input/output control means 111 as shown in FIG. 26, the attribute determining means 1124 as started carries out the following steps:
Step 3102: From a user category table (FIG. 27), attributes corresponding to the inputted user category are read. In the user category table, attributes corresponding to each user are described sequentially from the attribute with the highest priority. For "women" in the inputted user category, data such as presence or absence of street light, presence or absence of shops open till late at night, vehicular traffic density, crowdedness of pedestrians, presence or absence of police box are determined as attributes.
Step 3103: Next, attributes to correspond to the inputted weather are read from a weather category table (FIG. 28). In case the weather is "rain", the data such as presence or absence of underground passage, presence or absence of covering, presence or absence of roadside ditch, vehicular traffic density, or crowdedness of pedestrians are determined as attributes.
Step 3104: Next, attributes to correspond to the inputted time are read from a time category table (FIG. 28). From the inputted time "16:35", the data such as presence or absence of street light, crowdedness of pedestrians, and vehicular traffic density are determined as attributes by referring to "evening" category of the time category table.
Step 3105: Sum-set of attributes determined from each category table is calculated. At the same time, sum of priorities of the categories is obtained.
Step 3106: By this sum, priority rank of attribute of the sum-set is determined, and a predetermined number of attribute data with high priority rank are outputted as shown in FIG. 29.
The attribute determining means 1124 can determine attributes using a neural net. FIG. 30 shows a flow chart of the attribute determining means using a neural net. By the attribute searching means 1124 thus started;
Step 3202: The value Xi of the input item is digitized according to the inputted data as shown in FIG. 31.
Step 3203: From a table of weight constant "a ij" of input/output shown in FIG. 32, value Yj' of attribute of output item is calculated. In FIG. 32, numerals 1, 2, 3 . . . in longitudinal direction indicate input items of FIG. 31, and the numerals 1, 2, 3 . . . in lateral direction indicate attributes of output items. The value "a ij" of intersection of the input item "i" and the output item "j" indicates weight constant of the output item "j" to the input item "i". The value Yj' of attribute of the output item is calculated by: ΣXi "i").
Step 3204: As shown in FIG. 33, the output Yj' is compared with threshold (0.5). Output value Yj of attribute exceeding the threshold is set to 1, and priority rank of attributes is assigned in the descending order of the value Yj'.
Step 3205: The result of calculation is outputted by changing to natural language.
Also, the point-to-point route searching means 1122 of the pedestrian route searching means 112 executes route searching according to the procedure shown in FIG. 34. Explanation is given now on the case where a route is searched in a region shown in FIG. 35 as an example. In this figure, each region enclosed by curve indicates an area. Larger numeral indicates area number, and smaller numeral indicates street number. Straight line indicates a street.
In this example, the data shown in FIG. 36 are inputted, and a route from JR Roppongi Station to the destination, i.e. "Roppongi Murasaki", is searched.
It is now supposed that area data of FIG. 37A to FIG. 38C, block data of FIG. 39A to FIG. 41B, and street data of FIG. 42A to FIG. 48B are stored in the pedestrian map data 13. In actual conditions, the street data has many attributes as shown in (1) of FIG. 42A and FIG. 42B. Here, explanation is given on functions, and detailed attributes are not described for the street data (2) to (15). Also, polygonal information is not given in the area data, and polygonal information and 3-dimensional information are not given in the block data.
When the point-to-point route searching means 112 is started;
Step 4102: The attributes of the street to be searched are determined according to the input by the attribute determining means 1124. In this example, from the user category, i.e. a 72-year-old woman, attributes of the street to be searched are determined as: street light, shops open till late at night, vehicular traffic density, crowdedness of pedestrians, police boxes, and avoidance of parks and parking area, and the attributes are determined as: handrails, pavements, slopes, stairways, bicycles, and road width.
Step 4103: The corresponding data searching means 1141 is started to search an area, to which the departure point belongs, and 420b block and 35a area are found.
Step 4104: The corresponding data searching means 1142 is started to search an area, to which the destination belongs, and 443b block and 37a area are found.
Step 4105: The point-to-point problem between 35a area and 37a area is solved by Dijkstra method known as a solution of the problem of optimal route, and it is determined to pass through 11826st and 11835st.
Step 4106: From the streets satisfying the attributes as desired by the user in the streets within the area, a combination of streets, which constitute the shortest route, is obtained, and it is determined to pass through 11723st, 11727st, 11826st, 11733st, 11734st, 11835st, and 11747st.
Step 4107: Data of departure point, destination and the street to pass through are sent back.
FIG. 49 is a schematical drawing to show the case where the departure point is under the ground. In this case, also, route searching can be performed by the procedure as described above. The data shown in FIG. 50 are inputted, and a route from Roppongi Station of Hibiya Line of the subway to the destination "Roppongi Murasaki" is searched.
The route searching means 112 between two points is started, and attributes of the street to be searched are determined as described above according to the input.
The corresponding data searching means 1142 is started to search an area, to which the departure point belongs, and 260b block and 34a area are found. Then, an area, to which the destination belongs, is searched, and 483b block and 37a area are found.
Next, the point-to-point problem between 34a area and 37a area is solved, and it is determined to pass through 11827st and 11835st. Then, from the streets satisfying the attributes as desired by the user among the streets in the area, a combination of the streets which constitute the shortest route is obtained. It is determined to pass through 11711st, 11827st, 11738st, 11734st, 11835st and 11747st, and the data of departure point, destination and streets to pass through are sent back.
FIG. 51 and FIG. 52 each represents a schematical drawing to show the case where the departure point is under the ground and the destination is in a building. In this case, also, route searching can be carried out by the procedure as described above. It is now supposed that the data shown in FIG. 53 are inputted, and a route from "Roppongi Station of Hibiya Line" of the subway to the destination "TBS Studio 04" is searched.
The point-to-point route searching means 112 is started, and attributes of the street to be searched are determined according to the input as described above.
The corresponding data searching means 1142 is started to search an area, to which the departure point belongs, and 260b block and 34a area are found. Next, an area, to which the destination belongs, is searched, and 125b block and 1038a area are found.
Next, the point-to-point problem between 34a area and 1038a area is solved, and it is determined to pass through 11827st and 22800st. Then, from the streets satisfying the attributes desired by the user among the streets in the area, a combination of streets which constitute the shortest route is obtained. It is determined to pass through 11711st, 11827st, 11738st, 11734st, 22800st, and 22734st, and the data of departure point, destination and the streets to pass through are sent back.
The route searching means 1121 between a plurality of geographical points of the pedestrian route searching means 112 executes route searching according to the procedure of FIG. 54 in case there are two or more destinations. Explanation is now given on the case where the data shown in FIG. 55 are inputted, and a route is searched from departure point of "JR Roppongi Station" to pass through "Roppongi Murasaki", "Roppongi Kimidori", "Roppongi Daidai", "Roppongi Mizuiro", and "Roppongi Momoiro". FIG. 56 represents a schematical drawing to show this example.
The route searching means 1121 between a plurality of geographical points as started performs the following steps:
Step 5102: Attributes of the street to be searched are determined by the attribute determining means 1124. In this example, from the user category defining that the user is a 72-years-old woman, the attributes of the streets to be searched are determined as: street light, shops open till late at night, vehicular traffic density, crowdedness of pedestrians, police boxes, avoidance of parks and parking areas, handrails pavements, slopes, stairways, bicycles, and road width.
Step 5103: The corresponding data searching means 1142 is started to search an area, to which departure point and all of the destinations belong, and the following blocks and areas are found: 420b block and 35a area, 443b block and 37a area, 444b block and 37a area, 431b block and 36a area, 491b block and 39a area, and 391b block and 32a area.

Step 5105: From the streets satisfying the attributes desired by the user among the streets in the area, a combination of the streets constituting a go-round route is searched, and it is determined to pass through 11723st, 11727st, 11826st, 11731st, 11737st, 11836st, 11741st, 11742st, 11747st, 11743st, 11848st, 11797st, 11795st, 11792st, 11895st, and 11725st, 11892st, 11692st, 11693st, 11894st, 11720st, 11721st, and 11722st in this order.
Step 5106: The data of departure point, destination and all streets to pass through are sent back.
It is evident that distance and time are interchangeable with each other as indices in the route searching.
The route searching means 1123 of a plurality of transportation means executes selection of route using a plurality of transportation means by the procedure shown in FIG. 57. Explanation is given now on the case where the data shown in FIG. 58 are inputted, and a route is searched from "Shinagawa Murasaki" (with Aomono Yokocho Station of Keihin Express as the nearest station) to "Roppongi Murasaki" (with JR Roppongi Station as the nearest station). FIG. 59 shows a schematical drawing from the departure point "Shinagawa Murasaki" to the nearest station "Aomono Yokocho Station". FIG. 35 shows a schematical drawing from JR Roppongi Station to the destination "Roppongi Murasaki".
The route searching means 1123 of a plurality of transportation means as started performs the following steps:
Step 6102: Attributes of the streets to be searched are determined by the attribute determining means 1124.
Step 6103: The corresponding data searching means 1141 is started to search an area, to which departure point and destination belong, and 250b block and 25a area, and 483b block and 37a area are found.
Step 6104: The nearest information searching means 1142 is started to search stations, which are the nearest to the destination and the departure point respectively, and 270b block and 27a area, i.e. data for Aomono Yokocho Station of Keihin Express, and 470b block and 35a area, i.e. JR Roppongi Station, are found.
Step 6105: The point-to-point route searching means 1122 is started, and an optimal route of 250b block and 270b block is obtained. Further, an optimal route for 483b block and 470b block is obtained, and street data 11723st, 11727st, 11826st, 11733st, 11734st, 11835st, 11747st and 12423st, 12427st, 12426st, 12433st, 12434st, 12435st, and 12447st are obtained.
Step 6106: From the schedule of trains, a route of trains from Aomono Yokocho Station of Keihin Express to JR Roppongi Station is obtained.
Step 6107: The data of departure point, destination and the streets to pass through and the data of train schedule are sent back.
The time simulation means 116 simulates the time until the destination is reached by the procedure shown in FIG. 60.
The time simulation means 116 as started performs the following procedure:
Step 7102: Route searching is performed to correspond to the input (FIG. 61).
Step 7103: The obtained data are sequentially identified from the departure point. If it is a street data, the time required, the time of arrival, and the time of departure on each street are calculated from length of route and walking speed. If it is the schedule data, the time of departure at departure station, the time of arrival at the arrival station, and the time required are calculated by referring to the time table.
Step 7104: The calculated result is outputted in the data with the form as shown in FIG. 62.
In this example, the time of arrival is obtained by calculating from the departure time, while it is possible to obtain departure time by calculating from the time of arrival.
The scheduling means 113 sets up a schedule to go round a plurality of destinations by the procedure shown in FIG. 63.
The scheduling means 113 as started performs the following steps:
Step 8102: From the input data (FIG. 64), destinations (B, C, and E) with specified time are aligned in the order of the time (B, E, and C).
Step 8102: Destinations are searched between B and E and between E and C. If it is supposed that there is D between B and E, and there is F between E and C, permutation (B, D, E, F, C) is prepared.
Step 8104: The destination A without specified time other than the above is assigned before the time specifying or after time specifying, and a permutation (A, B, D, E, F, and C) are made up.
Step 8105: Route searching is performed according to the prepared permutation.
Step 8106: On the obtained route, time of arrival at each destination is simulated by starting the time simulation means 116.
Step 8107: On the geographical points B, C, and E with specified time, it is judged whether the specified time is followed or not.
Step 8110: If not followed, another permutation (B, D, E, F, C, A) is prepared, and Steps 8105 to 8107 are repeated.
Step 8108: Even when it is followed, if the user judges the result and does not accept it;
Step 8110: Again, a different permutation is prepared, and Steps 8105 to 8107 are repeated. In Step 8108, if the result is satisfactory, the procedure is completed.
If minimum value of the time to go through the route by Step 8108 is judged by computer, it is evident that it will be as given on a flow chart to obtain the shortest time.
By the procedure shown in FIG. 65, the transportation determining means 117 selects a transportation means, which can ensure the earliest time of arrival. Description is now given on the case where the data shown in FIG. 66 are inputted and it is searched by multi-mode a route departing from "Shinagawa Murasaki" at 12:00 and reaches "Roppongi Murasaki" at the earliest time (FIG. 35 and FIG. 59).
The transportation determining means 117 as started performs the following steps:
Step 9102: Attributes of the streets to be searched are determined according to the input using the attribute determining means 1124.
Step 9103: The corresponding data searching means 1141 is started, and area and blocks, to which departure point and destination belong, are searched, and 250b block and 25a area as well as 443b block and 37a area are found.
Step 9104: The nearest information searching means 1142 is started to search blocks and areas of bus stops, stations, ports, and airports nearest to the destination and the departure point. In the searching of the nearest bus stop, 12434st is obtained as the street, to which the nearest bus stop of the departure point belongs, and 11733st is obtained as the street, to which the nearest bus top of the destination belongs. In the searching of the nearest station, 240b block and 27a area are obtained as the data of Aomono Yokocho Station of Keihin Express, which is the nearest station of the departure point, and 420b block and 35a area are obtained as the data of JR Roppongi Station, which is the nearest station of the destination. In the searching of the nearest port, 4001a area and 432b block are obtained as the data of the nearest port of the departure point and the destination. In the searching of the nearest airport, 5002a area and 534b block are obtained as the data of the nearest airport of the departure point and the destination.
Step 9105: In case where the nearest bus stop, station, port or airport of the departure point and the destination are the same, it is determined to use a transportation means by excluding these. In this example, the nearest port and the nearest airport of the departure point and the destination are the same, and it is determined to use bus or train as transportation means.
Step 9106: The point-to-point route searching means 1122 is started to search a route from departure point and destination to the nearest station of the transportation means used. For the railroad station, the shortest route of 250b block and 240b block and the shortest route of 443b block and 420b block are obtained, and the street data of 11723st, 11727st, 11826st, 11733st, 11734st, 11835st, 11747st, and 12423st, 12427st, 12426st, 12433st, 12434st, 12435st, and 12447st are obtained. Also, for the bus stop, the shortest route of 250b block and 12434st and the shortest route of 443b block and 11733st are obtained, and the street data of 11733st, 11734st, 11835st, 11747st, and 12423st, 12427st, 12426st, 12433st, and 12434st are obtained.
Step 9107: Using schedule data, the time of arrival is calculated. With regard to bus, the time of arrival is calculated according to the bus schedule shown in FIG. 67. With regard to railroad, the time of arrival is calculated from the data of train schedule. Changing the modes of the transportation means used, the time of arrival at the destination is calculated as shown in FIG. 68, FIG. 69, and FIG. 62.
Step 9108: The data of the time of arrival are compared with each other, and the transportation means with the earliest time of arrival is adopted. In case the time of arrival is the same, the transportation means with lower cost is selected, and the result of FIG. 69 is adopted.
Step 9109: All of the routes and the lines adopted in Step 9108 (FIG. 69) are outputted.
Next, description will be given on how the pedestrian map data 13 are generated. The pedestrian map data 13 can be prepared using road map and street map as currently available.
The pedestrian map data generating and editing means 115 of the pedestrian information processing unit 11 generates the pedestrian map data from the road map by the procedure shown in FIG. 70.
The pedestrian map data generating and editing means 115 as started performs the following steps:
Step 9502: As shown in FIG. 71, basic road data (FIG. 74), data of river system, and data of railroad, which are non-pedestrian area data, are picked up from the road map data.
Step 9503: Intersections in the non-pedestrian area, i.e. points of intersection A/B/C/D/E/F between basic roads (road 1 to road 9) and between basic road and railroad 1, are obtained (FIG. 72). For each basic road, non-pedestrian area is determined by following the signal flag of all-road data. At the same time, the data of blocks and streets relating to the non-pedestrian area are prepared as shown in FIG. 75A to FIG. 75C.
Step 9504: Starting from an adequate point of intersection E, points of intersection obtained in Step 9503 are connected with each other counterclockwise (FIG. 73). In this case, if started from E, it goes up to the north and reaches D. Then, it is turned toward left. After reaching A, it is turned toward left. If this procedure is repeated, it goes round in the order of E→D→A→B→E, and this is determined as a contour of the pedestrian area. After confirming that the same contour is not yet registered, it is registered as an area ID 2345a in the pedestrian map data. Similarly, a region enclosed by contour of FEBCF is registered as an area ID 2346a as shown in FIG. 76.
Step 9505: Referring to the street map, it is calculated that the street block W1 is in the area 2345a using vertical line method, and it is registered as block data 2345b of the pedestrian map data. Similarly, W2 to W10 are registered as block data of the area 2345a. By the same procedure, the street block Q1 is registered as block data 2346b of the area 2346a. Similarly, the street blocks Q2 to Q15 are registered as block data of the area 2346a. W1 and Q1 are registered as shown in FIG. 77.
Step 9506: From the road map, it is calculated that there is a road a1 with width of 5.5 m or less in the area 2345a using vertical line method, and this is registered as the street data 2345st of the pedestrian map data. Similarly, the roads a2-a5, b1-bc, cl, z1-z2, y1-y3, x1-x2, and w1 are registered as streets of the area 2345a. Further, the road e3 with width of 5.5 m or less is registered as the street data 2346st of the area 2346a. Similarly, the roads a6, b4, c2-c3, d1, e1-e4, f1-f4, z3-z5, y4-y6, x3-x6, and w3-w6 are registered as the streets of the area 2346a as shown in FIG. 78.
Step 9507: Following the coordinates of starting point and end point of the streets, connecting street number of the starting point and the end point of the street is registered. From the data of street block, connecting street data of the block are registered. After registration, all of the geographical information are made subordinate to block and street as shown in FIG. 79.
Step 9508: All data are outputted and the procedure is completed.
Thus, the pedestrian map data generating and editing means 115 can automatically prepare pedestrian map data from road map data and street map data.
Also, the pedestrian map editing means may be simultaneously provided, by which the user can add, update or delete the pedestrian map data through user interface. In this case, the user can edit the generated pedestrian map data.
Also, in the pedestrian information providing system, it is possible to display buildings, landmarks, etc. 3-dimensionally at the time of outputting by adding 3-dimensional information to display 3-dimensional configuration to the data of each block and street.
2nd Embodiment
In the second embodiment, description will be given on the case where the pedestrian map data are generated mainly using street map. FIG. 80 shows the procedure of the pedestrian map data generating and editing means 115 in this case. FIGS. 81(a) to (d) each represents a schematical drawing to show operation of the pedestrian map data generating and editing means 115 to generate pedestrian map data from street map.
The pedestrian map data generating and editing means 115 as started performs the following steps:
Step 9702: From the street map data, all of the street block data A to T (FIGS. 81(a), and FIG. 82) are picked up and are stored in storage region.
Step 9703: Empty pedestrian area data "a" is prepared.
Step 9704: Street block data A is picked up, and this is registered in the pedestrian area data "a" as an object street block.
Step 9705: All street blocks, which are adjacent to the object street block A with a distance of 5.5 m or less are obtained.
Step 9706: It is judged whether a street block is present or not, which is a street block adjacent to the object street block with a distance of 5.5 m or less and which is not yet registered in the pedestrian area "a". If not present (not present in case of FIG. 81A);
Step 9709: It is judged whether there is data in storage region or not. If there is, it is moved to Step 9703.
In this case, the street block data is still in the storage region, and a new pedestrian area "b" is prepared (Step 9703), and the street block data B is picked up, and it is registered as an object street block in the pedestrian area "b" (Step 9704). Then, all street blocks adjacent to the object street block B by a distance of 5.5 m or less are searched (Step 9705). In this case, the street block C is found as such. It is then judged whether there is a street block not yet registered in the pedestrian area "b" (Step 9706). In this case, the street block C is not yet registered.
Step 9707: The street block C is added to the pedestrian area "b", and the street block C is deleted from the storage region.
Step 9708: Among the street blocks added to the area "b", the street block C not yet considered as the object street block is turned to the object street block.
Step 9705: A street block adjacent to C is obtained.
By repeating the procedure of Steps 9705 to 9708, the street blocks B, C, D and E are registered to the area "b".
Similarly, the street blocks are continuously registered to the area until there is no more street block data from the storage region. When there is no more street block data in the storage region (Step 9709);
Step 9710: Line segments of the street block data in each of the pedestrian areas are extracted as roads of 5.5 m or less (FIG. 83 and FIG. 81C), and these are added to the street data.
Step 9711: The street block data in each of the pedestrian areas are registered as block data. In this case, the pedestrian data are prepared as shown in FIG. 84.
Step 9712: Referring to the road data, non-pedestrian area data are prepared as shown in FIG. 81D.
Step 9713: All of the prepared data are outputted, and the procedure is completed.
In this way, the pedestrian map data generating and editing means 115 can automatically generate the pedestrian map data by mainly using street map.
The pedestrian map data generating and editing means may be arranged in such manner that it comprises a pedestrian map data generating means for preparing pedestrian map data from existing road map as explained in the first embodiment and a pedestrian map data generating means for preparing a pedestrian map data from the street map as explained in the second embodiment.
3rd Embodiment
In the third embodiment, description will be given on a pedestrian map data generating and editing means for determining pedestrian area from a road map data by a simple method. FIG. 138 is a flow chart to show operating procedure of the pedestrian map data generating and editing means, and FIGS. 139A and 139B schematically illustrate a pedestrian area generated from a road map by this method. FIG. 139A shows a road network near a node A in the road map. Thick lines indicate basic roads, and thin lines (thin lines are concealed under thick lines) indicate all roads. By the procedure given below, the pedestrian map data generating and editing means generates each of pedestrian areas shown in FIG. 139B from the data of the road network.
The pedestrian map data generating and editing means as started performs the following steps:
Step 002: Basic road data, river system data and railroad data are picked up from the road map data. Thus, the data of the road network of FIG. 139(a) are picked up.
Step 003: The data of each node of the basic road are duplicated, and number of the nodes is increased up to the degree of the node. The degree is defined as number of links entering the node. The degree at the node A in FIG. 139A is 4, and the degree at the node B is 2. Therefore, for the data of the node A with the degree 4, the number of the data is increased to 4 by duplication. As shown in FIGS. 140 and 140B, this means that the node A is split to 4 nodes of Al, A2, A3 and A4.
The node A1 thus split is turned to a node having an internal angle A1 connected to two links adjacent to A, i.e. a link with the node "a", and a link with the node "b". Also, the node A2 is turned to a node having an internal angle A2 connected to two links, i.e. a link between A and the node "b" and link between A and the node "c". The node A3 is turned to a node having an internal angle A3 connected to two adjacent links, i.e. a link between A and the node "c" and a link between A and the node "d". Also, the node A4 is turned to a node having an internal angle A4 connected to two adjacent links, i.e. a link between A and the node "d" and a link between A and node "a". However, in this stage where the node is simply split, connection information between nodes remain the same. As shown in FIG. 140(b), the node A1 is connected not only with the nodes a1 and b1 but also with the nodes a2, b2, c1, c2, d1, and d2. Similarly, the nodes of A2, A3 and A4 are also connected to each of the nodes a1, a2, b1, b2, c1, c2, d1, and d2.
Step 004: For the node A1, the connections with the nodes b2, c1, c2, d1, d2, and a2 not found inside the internal angle A1 are cut off. Also, for A2, A3, and A4, the connections to the nodes which are not within the internal angles A2, A3 or A3 are cut off. By this processing, connections between the nodes are turned to the state as shown in FIG. 140C. After the same procedure has been performed for all of the nodes;
Step 005: The procedure is completed.
As the result of this processing, a pedestrian area as shown in FIG. 139B is prepared.
By this method, it is possible to prepare a pedestrian area in simple and quick manner from the road data.
4th Embodiment
In the fourth embodiment, description will be given on the pedestrian map data generating and editing means for determining a pedestrian area from a road map data in simple manner. FIG. 141 is a flow chart to show operating procedure of the pedestrian map data generating and editing means, and FIGS. 142A and 142B schematically illustrate a pedestrian area generated from the road map by this method.
The pedestrian map data generating and editing means as started performs the following steps:
Step 012: Basic road data, river system data, and railroad data are picked up from the road map data. Thus, the data of the road network of FIG. 142A are picked up.
Step 013: Route searching is started form nodes of all arbitrary roads to all bearings (directions), and route searching is continued until each of the search leaves (tips of search) reaches a basic road. This is illustrated in FIGS. 143A to. FIG. 143A shows a node "a" of each road, for which route searching is started, and FIG. 143B indicates a stage where processing has proceeded from the node "a" to the second node. Broken lines show the links passed through. All nodes passed through and all links are stored in memory. As shown in FIG. 143C, when all of the search leaves reach the basic road, the searching is terminated.
Step 014: All-road nodes passed through, all-road links and basic road nodes and links reached are considered as one group. The connection with the nodes which are not found in this group is cut off, and this is registered as a pedestrian area.
Step 015: The procedure from Step 013 to Step 014 is repeated until all-road data are registered in the area data.
Step 016: When all-road data are registered in the area data, this processing is terminated.
As the result of this processing, a pedestrian area shown in FIG. 142B is formed. By this method, the pedestrian area can be generated by repeating simple procedure from the road map data. Even when attribute information to show degree in the nodes of basic road is not prepared satisfactorily, the pedestrian area can be generated by this method.
5th Embodiment
In the fifth embodiment, description will be given on a method to split one area to a plurality of areas. If number of areas is increased, the burden applied on generation of the pedestrian map data is increased. For this reason, narrow rivers and the like are not discriminated as non-pedestrian area in the initial stage and are included in the pedestrian area. Only when the need to discriminate becomes apparent, it is divided to a plurality of areas. This will make it possible to more efficiently perform generation and searching of the pedestrian map data from general viewpoint.
In such case, flow rate of pedestrians in each link of all roads is calculated in this embodiment. If there are several streets parallel to each other, the flow rate in each street decreases. On the contrary, in case pedestrians from several streets enter a single street, the flow rate of this street increases because it is a sum of the flow rates of all of these streets.
In case there is a link where flow rate exceeds a predetermined value, this link is determined as a street to go over a non-pedestrian area (i.e. If non-pedestrian area is a river, the street is a bridge. If non-pedestrian area is a road, the street is pedestrians' crossing or footbridge.), and the area is split. If there is no link where flow rate exceeds a predetermined value, splitting of the area is not performed.
FIG. 144 is a flow chart to show operating procedure of the pedestrian map data generating and editing means in this case. FIG. 145, FIG. 146, and FIG. 147 each represents a schematical drawing to explain this operation.
The pedestrian map data generating and editing means as started performs the followings steps:
Step 022: From the pedestrian route data, an area data is picked up. Explanation is now given on a case where there is an area data as shown in FIG. 145 and a bridge is detected from an area A. FIG. 146 is an enlarged view of the area A.
Step 023: From all-road node "a" of the area A, flow rate of each link is calculated toward all bearings within the area A.
Step 024: It is checked whether there is a link where flow rate exceeds a predetermined value or not. Flow rate exceeds a predetermined value in each of the links b, c, and d in FIG. 146, and the links b, c, and d are detected as bridges.
Step 025: With the links b, c, and d as borders, the area is split as shown in FIG. 147 to turn it to a new area A1 and a new area A2.
Step 026: For all of the area data, the procedure from Step 023 to Step 025 is repeated.
Step 027: When processing is completed for all of the area data, splitting of the area is terminated.
In this method, only the areas relating to a link with high priority are divided, and the other areas are included in the pedestrian area. In so doing, it is possible to alleviate the burden on generation of the pedestrian map data.
Also, by this method, it is possible to recognize a bridge in the pedestrian map even when attribute information on the road map is not prepared satisfactorily.
6th Embodiment
In the sixth embodiment, description will be given on operation of the pedestrian map data generating and editing means 115, which generates the data of streets from a map data showing a premise such as underground shopping center or facilities.
The pedestrian map data generating and editing means 115 extracts streets by a procedure shown in FIG. 111 from a vector diagram of a premise map. As an example, explanation is given now on the premise drawing shown in FIG. 112.
Step 1010: Sides a, b, c, and d, which serve as entrances or exits in the premise drawing, are inputted.
Step 1020: The pedestrian map data generating and editing means 115 prepares a Voronoi diagram in the premise using vertexes shown by black circles in the premise drawing (FIG. 112) read from the pedestrian map data 13 as question points. In this diagram, borders to indicate spheres of influence of each question point are as shown by broken lines in FIG. 113.
Step 1030: Of the borders indicated by broken lines, line segments in contact with sides other than a, b, c, and d are deleted. Only the line segments shown by thick lines in FIG. 114 are left.
Step 1040: Next, of the remaining line segments, the line segments, whose end point is not connected to any side or to any line, are deleted. By this processing, only the line segments shown by thick lines in FIG. 115 are left.
Step 1050: When points (q, r) where three or more of the remaining line segments cross each other and points (p, s, t, u), which are on the sides a, b, c or d, and serving as entrance or exit, are indicated by black circles, each continuous line segment from a black circle to a black circle as shown in FIG. 116 is registered as a street. Also, bending point of this street and points of intersection with border in Voronoi diagram are registered as interpolation points of the street. Thus, street data of the premise are generated.
7th Embodiment
In the seventh embodiment, description will be given on a method to correct the generated pedestrian area data. On the generation of the pedestrian area data, explanation has already been given using the flow chart of FIG. 70. Specifically, the pedestrian map data generating and editing means 115 reads road map data and street map data. First, using the road map data, a region and contour streets of the pedestrian area are picked up by starting from intersection point of major roads and by returning to initial intersection point by following the major road clockwise or counterclockwise. Then, these are registered. Next, using the street map data, street blocks and facilities in the pedestrian area are picked up by point position determining method such as vertical line method, and these are registered.
However, this method combines what are obtained from two types of map data, and contour streets of the pedestrian area indicated by thick lines and street blocks and facilities indicated by thin lines may be deviated as shown in FIG. 126, and blanks may be generated between them.
In the seventh embodiment, description will be given on a method, by which it is possible to correct the pedestrian area data having blanks as shown in FIG. 126 to pedestrian area data, in which there are contour streets along peripheries of facilities and street blocks and which are closer to actual conditions.
The pedestrian map data generating and editing means 115 generates the corrected pedestrian area data by a procedure shown in FIG. 125.
In the procedure given in FIG. 125, the procedure from Step 302 to Step 307 is the same as the procedure from Step 9502 to Step 9507 of FIG. 70, and it is the procedure to generate the pedestrian area data of FIG. 126.
Step 308: The pedestrian map data generating and editing means 115 correct the data of the pedestrian area thus obtained to the data closer to the actual condition.
In the correcting procedure, for example, by applying convex closure method to street blocks in the pedestrian area as shown in FIG. 127, contour streets indicated by broken lines are obtained. Then, the portion indicated by the broken lines is registered as a new pedestrian area as shown in FIG. 128.
Convex closure (or convex hull) method is a method, in which a straight line at the outermost position is selected when a straight line is drawn from a certain vertex of a street block to each vertex of the other street block, and from the vertex connected by this straight line, a straight line at the outermost position is selected when straight lines are drawn similarly to each vertex of the other. By repeating this procedure sequentially, a polygon is obtained.
The correction of the pedestrian area data of FIG. 126 can be performed by the procedure of FIG. 129.
Step 402: Of the vertexes constituting a street block, from all vertexes, which are within a predetermined distance from the contour road, lines are drawn perpendicularly to the nearest contour road. If the vertical line does not cross a line segment of the other street block, this vertex is considered as the vertex of the contour street.
Step 403: By connecting the vertexes thus obtained, a contour street shown by broken line in FIG. 130 is obtained.
Step 404: The portion indicated by the broken lines is registered as a new pedestrian area as shown in FIG. 131.
By this method, it is possible to obtain contour streets, which are running along the street block and are closer to actual condition than the contour streets obtained by the convex closure method (FIG. 128).
Also, the correction of the pedestrian area data of FIG. 126 can be performed by the procedure of FIG. 132.
Step 501: As shown in FIG. 133, the center (black circle) of the area is obtained.
Step 502: A straight line is drawn, which passes through vertexes constituting a street block (vertexes which are within a predetermined distance to contour street) or a point on a line segment of the street block and the center of the area. If the line segment of the street block, which crosses this straight line, is not at a position outer than the vertex (or a point on the line segment), this point is considered as the vertex of the contour street.
Step 503: By connecting the vertexes thus obtained, a contour street shown by broken line in FIG. 133 is obtained.
Step 504: The portion indicated by the broken line is registered as a new pedestrian area as shown in FIG. 134.
The correcting method of FIG. 126 and FIG. 132 is applied only to vertex or line segment, which is within a predetermined distance to the contour road. The distance from the contour road may be changed in such manner that it is shorter when road width of the contour link is wider, and the distance is longer when the road width is narrower.
In this way, by correcting the data of the pedestrian area to the condition closer to actual condition, it is possible to provide more accurate route guidance for pedestrians.
8th Embodiment
In the eight embodiment, description will be given on the pedestrian map data generating and editing means for generating pedestrian map data by adequately using the methods as described above.
As shown in FIG. 148, this pedestrian map data generating and editing means comprises a first pedestrian map data generating means 1151 for performing a method to generate pedestrian map data using a road map and a street map as explained in the first embodiment, a second pedestrian map data generating means 1152 for performing a method to generate the pedestrian map data using a street map data explained in the second embodiment, a third pedestrian map data generating means 1153 for performing a method to generate a pedestrian area by splitting a road map data as explained in the third embodiment, a fourth pedestrian map data generating means 1154 for performing method to generate a pedestrian map data by grouping links and nodes where leaf of route searching reaches basic road as explained in the fourth embodiment, a fifth pedestrian map data generating means 115 for generating data of streets from premise map data as explained in the sixth embodiment, a pedestrian bridge detecting means 1156 for performing a method to detect a link with higher flow rate and to split relevant areas as explained in the fifth embodiment, a first pedestrian map data correcting means 1157 for performing a method to correct pedestrian area data shown in FIG. 125, a second pedestrian map data correcting means 1158 for performing a method to correct pedestrian area data shown in FIG. 129, a third pedestrian map data correcting means for performing a method to correct pedestrian area data shown in FIG. 132, and a generating means determining means 1160 for selecting and starting one of the means 1151 to 1159.
Upon receipt of the parameters relating to map data generation from the input/output control means 111, the generating means determining means 1160 starts map data generating means and correcting means in response to the parameters and generates a pedestrian map data.
By this pedestrian map data generating and editing means, pedestrian map data with less errors can be efficiently generated by combining various types of pedestrian map data generating means and correcting means.
9th Embodiment
The pedestrian information providing system of the ninth embodiment of the invention can provide route information for pedestrians in a manner easily understandable to the pedestrians.
The present system comprises the arrangements of FIG. 1, FIG. 2, and FIG. 3 similar to the first embodiment as hardware arrangement. The pedestrian route searching means 112 of the present system searches with priority a sidewalk of a contour road (contour street) in contact with outer periphery of a pedestrian area. The input/output control means 111 converts a route searched by the pedestrian route searching means 112 to a route information data shown in icons and outputs it, and icons are displayed on a display screen of the portable terminal equipment, which receives the data.
First, on the route searching with priority on the contour street by the pedestrian route searching means 112, description will be given on the schematical map of FIG. 86 as an example. The results of the route searching are shown by thick lines in FIG. 87.
The pedestrian route searching means 112 performs route searching by the procedure shown in FIG. 85.
Step 020: In an area (A), to which the departure point (Start) belongs, a street (sidewalk) of a contour road (a) with the shortest straight distance from the departure point is obtained (this is called "the nearest street"), and a route (α) from the departure point to the nearest street is obtained.
Step 030: In an area (C), to which the destination (End) belongs, the nearest street (e) of the contour road with the shortest straight distance from the destination is obtained, and a route (β) from the departure point to the nearest street is obtained.
Step 040: Next, an area is obtained, which is to be passed through when going from the departure area (A) to the destination area (C) (A→B→C). Then, a bridge to pass when going from an area to another area, and a street, with which the bridge is in contact (BS) (street "d" in the area A, streets "a" and "e" in the area B, and street "b" in the area C) are obtained.
Step 050: Next, in the departure area (A), a contour street from the nearest street (a) to BS street (d) in contact with the bridge is obtained. In the destination area (C), a contour street from the nearest street (e) to BS street (b) is obtained. In the other area (B), a contour street from one BS street (a) to the other BS street (e) is obtained. In this case, the pedestrian route searching means 112 determines whether to turn round clockwise or counterclockwise according to the time required, attribute, etc.
Step 060: The pedestrian route searching means 112 searches a route from the departure point to the destination as shown by thick lines in FIG. 87, and the route data (shown in FIG. 88) thus obtained are outputted sequentially to the input/output control means 111.
The route searching for pedestrian with priority on the contour street can be efficiently performed by preparing the data arrangement of the pedestrian map data 13 as given below.
First, the streets in the pedestrian area are classified to contour streets and streets inside the area. For the contour streets, one street is used as a starting point, and street data are sequentially arranged clockwise or counterclockwise from that point.
In this case, after the nearest street and the BS street and the BS street have been obtained, the pedestrian route searching means 112 can obtain data of a series of contour streets by sequentially reading adjacent street data to correspond to advancing direction of the pedestrian by following the arrangement of the data.
When the route data of the results of searching are inputted from the pedestrian route searching means 112, the input/output control means 111 outputs the data of the contour street instead of the route information data of icons. On the other hand, the portable terminal equipment is provided with characters to match the data of icons. On the display screen of the portable terminal equipment, route information in icons is displayed according to the data sent from the input/output control means 111.
FIG. 90 shows an example of route information in icons relating to a contour road. Advancing direction of the pedestrian is displayed in relation to advancing direction of vehicles along a traffic lane closer to sidewalk of the contour road. Also, information data such as facilities along the road, distance of the street, etc. are displayed at the same time.
The input/output control means 111 prepares and outputs route information in icons relating to the contour street by the procedure shown in FIG. 89.
Step 120: Route data of the results of route searching processing is inputted from the pedestrian route searching means 112.
Step 125: In each of the areas, it is judged whether the pedestrians turn round the contour road from the starting point to the end point clockwise or counterclockwise. In case the pedestrians turn clockwise, icon information is prepared in such manner that advancing direction of vehicles is opposite to advancing direction of pedestrians. In case the pedestrians turn counterclockwise, it is prepared in such manner that advancing direction of vehicles is consistent with advancing direction of pedestrians. This is because, in the countries where vehicles are driven on the left side of road, vehicles are driven counterclockwise on the lane closer to outer periphery of the pedestrian area.
Step 130: When facility data are assigned to the street along the route, icon information to match the facility data is outputted. In the example of FIG. 87, when going round the contour street of the area A, there is a bank on the street "b", and a mark for bank is displayed. There is a post office on the street "c", and a mark for post office is displayed. In this case, if these facilities are on this side (as seen from the reader) of the contour road, marks of these facilities are displayed under an arrow, which indicates advancing direction of the pedestrian. If these facilities are on the other side of the contour road, marks of these facilities are displayed above the arrow. In case advancing direction of vehicles is consistent with advancing direction of pedestrians, a vehicle mark facing toward the direction of the arrow is displayed under the arrow. In case advancing direction of vehicles is opposite to advancing direction of the pedestrians, a vehicle mark facing toward the direction opposite to the arrow is displayed above the arrow. Also, a distance to a pedestrians' crossing to go over to the next area is displayed on the side of an arrow without vehicle mark.
Step 140: Going from an area to the next area is displayed by drawing a pedestrians' crossing in front of an arrow.
Step 150: Procedure from Step 125 to Step 140 is repeated from the area of the starting point to the area of the end point. In the area B, advancing direction of pedestrians is counterclockwise from the street "a" to the street "e", and a vehicle mark facing toward the direction of the arrow is displayed under the arrow. The marks of pedestrians' crossing, NTT company and fire department which are found when going along the streets "a", "f" and "e" are displayed. Also, a distance from the pedestrians' crossing of the street "a" to the pedestrians' crossing of the street "e", i.e. end point of the area B, is displayed. Similarly, in the area C, advancing direction of pedestrians is clockwise, and a vehicle mark facing toward the direction opposite to the arrow is displayed above the arrow, and marks of parking area and park which are found when going along the streets "c" and "d" are displayed. Also, a distance from pedestrians' crossing of the street "b" to the street "e" is displayed.
For the starting point area A, a route from the searched starting point to the nearest street "a" of the contour road is displayed on a map as shown in FIG. 91. For the end point area C, a route from the nearest street "e" to the end point is displayed on a map as shown in FIG. 92.
Thus, the present system can provide guidance with priority on the contour road with heavy traffic and give instruction on advancing direction of pedestrians in relation with the flow of vehicles. For this reason, pedestrians can easily understand which route should be followed even when there is no direct indication such as map or landmark when they are away from the departure point and the destination.
In the present system, a route guidance is provided by icons. By preparing characters to match landmarks, arrows, vehicles, etc. on the portable terminal equipment, it is possible to decrease the amount of data transfer to the portable terminal equipment.
10th Embodiment
In the pedestrian information providing system of the tenth embodiment, map data to be offered are deformed, and the amount of data to be transferred to the portable terminal equipment is decreased.
In the present system, when the pedestrian route searching means 112 searches a route for pedestrians, the input/output control means 111 deforms the data and sends it to the portable terminal equipment.
The input/output control means 111 performs this deforming processing according to the procedure shown in FIG. 93.
Step 210: When route search processing by the pedestrian route searching means 112 is completed and map data and the searched route are inputted;
Step 220: The input/output control means 111 deletes a road not found along the route from the map data and extracts characteristic points on line segment of each road along the route.
FIG. 94 shows an example of map data when deforming processing is performed, and FIG. 95 represents results of route search processing by the pedestrian route searching means 112. In Step 220, as shown in FIG. 96, departure point and destination of the route from A to B as indicated by thick lines and intersections where the route crosses the other roads are extracted. In FIG. 96, these points are indicated with black circles. Next, a road "b", which is not related to the route from A to B, is deleted. Then, as shown in FIG. 97, characteristic points along links connecting between the black circles are extracted. In FIG. 97, the extracted characteristic points are indicated with black rectangles. For the link "a", points a1 and a2 are extracted as characteristics points, and point a3 is not extracted as characteristic point.
Step 230: The input/output control means 111 draws a curve, which passes through black circles along each link and has black rectangles as interpolation points, using polynomial approximate function. Coefficient of the function is calculated, and coordinates of starting point and end point of each link and the calculated coefficient are outputted to the portable terminal equipment.
For example, when a value:
y=a n
is used as the polynomial approximate function, the values of coefficients a n, a n-1 . . . and the value of x of the starting point and the end point of link are outputted to the portable terminal equipment as shown in FIG. 100. The portable terminal equipment introduces the given values to the polynomial approximate function, and x-y coordinates of the starting point and the end point of the link and shape of the link passing through the starting point and the end point are reproduced. In case of a road running along y-axis, link shape can be more easily given by a polynomial using inverse function. Thus, inverse function is used. In this case, an inverse function flag is added to facilitate the identification.
FIG. 98 shows a deformed map, which can be reproduced at the portable terminal equipment. On a deformed map, a route shown in FIG. 99 is displayed.
Thus, in the present system, the amount of data to be transferred to the portable terminal equipment can be reduced by deforming of the map. For this reason, it is possible to provide route information to the portable terminal equipment at high speed. Also, it is possible to transfer a plurality of geographical information to the portable terminal equipment and to display a plurality of maps simultaneously on the screen of the portable terminal equipment.
11th Embodiment
In the pedestrian information providing system of the eleventh embodiment, unlike the case of the tenth embodiment, map data are deformed using the moving average method. The input/output control means of this system performs the deforming processing according to the procedure shown in FIG. 101.
Step 310: When route search processing by the pedestrian route searching means 112 is completed and the map data and the searched route are inputted;
Step 320: The input/output control means 111 extracts departure point and destination of this route and also intersection where this route crosses the other roads from the map data. Also, roads not found along the route are deleted, and an interpolation point of the links connecting between the intersections is obtained by 3-point moving average method.
It is now supposed that the deforming processing is performed on the map of FIG. 94 and that the result of route search processing by the pedestrian route searching means 112 is as shown in FIG. 95. The extraction of departure point and destination of the route and the intersection and deletion of the road not found along the route in Step 320 are performed by the same procedure as in the tenth embodiment. The departure point, destination and intersections thus extracted are indicated with black circles in FIG. 102. For the links connecting between intersections, coordinates of geographical points at every constant distance along the link are obtained. By deviating these points one by one, average value of coordinates to 3 geographical points is calculated. The average point is set as an interpolation point. In FIG. 102, the interpolation points are indicated with black rectangles.
Step 330: The input/output control means 111 outputs coordinate data of the departure point, destination points, intersections and interpolation points of the route thus obtained to the portable terminal equipment.
In the portable terminal equipment, a map as shown in FIG. 103 is displayed by connecting these points, and the searched route is displayed as shown in FIG. 104. In this way, according to the present system, the map is deformed by simple calculation, and the amount of data to be transferred to the portable terminal equipment can be reduced.
12th Embodiment
In the pedestrian information providing system of the twelfth embodiment of the invention, guidance is provided on a route in underground shopping center or in a building by indicating what can be seen on lateral sides when pedestrians advance along the route. In the pedestrian map data 13 of this system, map data showing a premise such as underground shopping center/buildings shown in FIG. 106 are retained. Also, as the data of the facilities in the premise, graphic data of the facilities given below, attribute information such as position, height, etc. are retained:
Notice board/guide board/escalator/elevator/toilet/coin locker/telephone box/hydrant/stairway/emergency exit/shops/clocks/(train stop position/vehicle number)/information of nodes and links in the premise
The structure of the data of the facilities is the same as that of the data of normal facilities.
From the map data of FIG. 106, the data of the streets in the premise as shown by broken lines in FIG. 107 are generated by the pedestrian map data generating and editing means 115 (the sixth embodiment), and these street data are retained in the pedestrian map data 13. The structure of the street data is the same as that of the normal street data.
The pedestrian route searching means 112 searches a route in the premise using the street data in the premise, and the results of searching are outputted to the input/output control means 111. Upon receipt of these data, the input/output control means 111 reads graphic data of the pedestrian map data 13 and provides information on a side view of the premise along the pedestrian route. The input/output control means 111 performs this operation according to the procedure shown in FIG. 105. Here, description will be given on a case where a street is passed through in the order of A→D→E as a route.
Step 410: The user specifies either the right side or the left side as a lateral view to be displayed (it is supposed that the right side is specified in this case).
Step 420: When the searched routes A, D and E are inputted from the pedestrian route searching manes 112;
Step 430: The input/output control means 111 follows this route sequentially and draws a perpendicular line on the right side of each of all streets passing through, and objects, which cross the perpendicular lines, are displayed on after another.
FIG. 108 shows a side view to be displayed on the screen of the portable terminal equipment according to graphic data outputted from the input/output control means 111. First, when we look at the right side of the street A in FIG. 107, wall/notice board/corner/coin-operated locker/corner/wall can be seen one after another. The input/output control means 111 refers to the corresponding facility data, determines size of characters and displays them. Next, along the street D, wall/corner/guide board can be seen, and these are displayed. Next, for the street E, guide board/wall/stairway can be seen, and these are displayed. On the street E, the route in the premise comes to an end, and the processing is terminated.
As described above, it is possible in the present system to provide guidance on a route in the premise by side view.
Also, it is possible in this system to provide guidance not only for underground shopping center or in a building, but also for platform of a station. FIG. 109 and FIG. 110 each represents an example of a station platform displayed from lateral side. In the guidance for the premise of a station, side view of platform is generated and registered in advance according to the procedure described above for each station, and the registered side view may be displayed upon request of the user on route guidance.
13th Embodiment
In the thirteenth embodiment of the invention, description will be given on a method to directly search a route between two points from a vector diagram of the premise.
The pedestrian route searching means 112 can search a route in the premise according to the procedure of FIG. 117 even when street data of the premise are not prepared satisfactorily.
Step 2010: For example, when a starting point "b" and an end point "a" are inputted in a premise drawing shown in FIG. 118;
Step 2020: The pedestrian route searching means 112 obtains a vertex, which interrupts light beam for the first time when the light beam is irradiated from the starting point "b" toward the end point "a". Next, from this vertex, the light beam is irradiated in the same manner, and a vertex is obtained, which interrupts the light beam for the first time when the irradiating direction of the light beam is moved toward the end point "a". By repeating this procedure until the light beam reaches the end point "a", a broken line approximate function from "b" to "a" as indicated by black thick line in FIG. 119 is obtained.
Step 2030: Next, as shown in FIG. 120, bending point of the broken line at the vertex of a polygon of the premise drawing is slightly moved toward inner side of the premise, and the broken line is separated from the vertex of the polygon of the premise drawing.
FIG. 121 to FIG. 123 each represents a procedure to obtain a route from the starting point "b" to the end point "d" by the same method. Thus, it is possible according to the present system to directly search a route in the premise from a vector diagram of the premise even when the street data of the premise are not available.
As shown in FIG. 124, in case there are blind alleys such as "a", "b" and "c" in the premise map, by performing processing to remove excessive leaves (alleys) in advance, it is possible to reduce the amount of calculation in the street extraction processing in the sixth embodiment or in the route search processing by broken line approximation in the thirteenth embodiment.
14th Embodiment
In the pedestrian information providing system of the fourteenth embodiment, shape of intersections of the route for pedestrians are presented to pedestrians in a manner easily visible. The input/output control means 11 of the present system enlarges and displays the intersection by the procedure shown in FIG. 135.
Step 2010: Intersections along the searched route for pedestrian are extracted.
Step 2020: By referring to information such as town information recorded on the pedestrian map data 13, a map of the vicinity of the intersection is prepared, and this is attached on the extracted intersection.
FIG. 136 shows a route for pedestrians thus searched, and FIG. 137 represents enlarged maps each attached near each intersection on the map. By overlapping the enlarged view of intersection on the map, pedestrians can more easily understand the route to be followed than the case where these are displayed separately. The enlarged view of the intersection may be overlapped near the intersection on the map.
In this way, the pedestrian information providing system of the present invention can provide information useful for pedestrians in a manner easily understandable as explained in connection with the above embodiments. Various types of data as illustrated here are presented simply as examples. The invention is not limited to these examples, and various modifications and additions can be made. For example, a place of a bench for elderly people may be added as attribute of the street data, and more elaborate route searching information can be provided for elderly people.
In the embodiments described above, description has been given on the terminal equipment on the user side, provided with an arrangement of a pedestrian information processing unit 11, which reads the pedestrian map data 13 stored in a storage unit at the center and performs a predetermined processing and displays the result of the processing to the screen of the terminal equipment, while it may be designed in such manner that a storage unit with pedestrian map data recorded may be incorporated in advance in the user terminal, i.e. the portable terminal equipment. In this case, wireless communication between the center and the portable terminal equipment is not required.
As it is evident from the above description, upon request from the user, who is a pedestrian, the pedestrian information providing system of the present invention can execute searching of the corresponding map and route searching at high speed and can provide various types of information useful for pedestrians and suitable for walking condition. Also, it is possible to provide guidance information for underground shopping centers, buildings, intersections or contour roads in a manner easily understandable for pedestrians. Further, it is possible to provide information quickly to the portable terminal equipment because the amount of data transfer can be reduced.

FIELD OF THE INVENTION
The present invention relates to a system for providing visible map information to pedestrians, and in particular, to a pedestrian information providing system for providing map data corresponding to information such as an address or latitude and longitude already inputted, and also for providing a route to walk to a destination in a manner visible to pedestrians.
BACKGROUND ART
A number of patent applications have been filed on navigation systems for automotive vehicles, while there have been very few applications, which proposed information providing system for providing map data and various other information for pedestrians. One of the systems for providing map information for pedestrians is proposed as "Portable Map Display System" in a Japanese Patent No.1895897 (Patent Application Publication JP-B-6-19276). This is a system which provides pedestrians with route information obtained from a road map.
Also, in the reference "Proposal of a Portable Information Providing System for Personal Trip", (Shimamura, Y. et al.: Journal of Association of Image Electronics, Vol. 23, No. 5, 1994, pp 422-427), a system is proposed, which searches a present position of a pedestrian on road and displays the position in a map on screen. This system is designed in such manner that, each time the pedestrian passes through an intersection, the user clicks advancing direction by selecting an intersection from configuration of the intersections displayed on screen. By repeating this procedure, walking speed of the pedestrian is calculated from the distance between the intersection and the time required. Also, the present position of the pedestrian is detected from amount of moving of the pedestrian and advancing direction at the intersection, and a doll icon is displayed at the present position in a map displayed on screen.
As a system for providing information by searching a route, various types of route guidance systems have been proposed, for example, in "Route Guidance System for Pedestrians", (Kato M., Association of Electronic Information and Communication, System Branch, Nationwide Meeting, 632), "Optimal Route Information Providing System in Urban Transportation" (Kato M., Association of Information Processing, Vol. 28, No. 3, pp. 307-314), etc.
In the conventional type system, however, pedestrian route is searched according to a road map, and pedestrian route well-matched to actual walking condition is not always searched, e.g. walking over pedestrians' crossing or footbridge when walking across a road.
Also, some pedestrians need to avoid a route with stairway, or in case of a woman, a road with good street light must be selected during nighttime. Thus, strict selection must be made on route searching depending on the conditions of each pedestrian. In the conventional system, sufficient analysis is not performed on pedestrian conditions, and route selection well-matched to the conditions of pedestrians is not always carried out.
Also, the conventional system has problems in that it takes much time to solve the problems relating to the route, and it is not possible to generate the information to be offered at high speed.
Further, there are the following problems:
In the conventional system, which displays route information near the present position of the pedestrian, the provided route guidance is based on a road map, and display of guidance information such as intersection information is not easily understandable to the pedestrians.
Also, the conventional system does not have route data such as premise, underground shopping center, information inside a building, station platform, etc., and route guidance cannot be provided for pedestrians on these places.
In case route information is provided to portable terminal equipment of the user, much time is required for data transfer because there are a plenty of amount of data in map data. For this reason, it is not possible to simultaneously display a plurality of geographical information on the screen of the portable terminal equipment.
Also, the data base to be used when providing route information for pedestrians must be prepared from data such as road map or street map currently used. In order to have more effective system to provide pedestrian information, the data base must be prepared automatically and efficiently.

Even when attribute information on a road map is not prepared satisfactorily, it is possible by this method to recognize a bridge, i.e. a street going over a non-pedestrian area, in a pedestrian map by this method.
In the system according to claim 42 of the present invention, the pedestrian map data generating means generates a pedestrian map data by combining several of the generating methods described in claims 19, 20, 30, 33, 34, 35, 36, 38, 39, 40 and 41. By combining these methods, it is possible to efficiently generate a pedestrian map with less error.
The invention of claim 43 provides a storage unit for storing pedestrian map data, and it is a component element to constitute a pedestrian information providing system together with a pedestrian information processing unit, whereby the storage unit stores a data of an area divided to a nonpedestrian area where pedestrians cannot walk freely and a pedestrian area where pedestrians can walk freely, a data of street where pedestrians can walk within each of the areas, a data of block where pedestrians cannot walk in each of the areas, an index for searching the block or the street from an address or a name, and a table describing the areas belonging to each section on a map. It is possible to provide the user with information such as useful route information or information on adequate pedestrian route suitable for pedestrians and walking conditions, or information such as map data of the vicinity of destination and departure point via the pedestrian information processing unit.
The invention of claim 44 provides a pedestrian information processing unit, which is a component element to constitute a pedestrian information providing system together with a pedestrian map data storage unit, whereby the pedestrian information processing unit comprises an input/output control means for receiving input from the user, a pedestrian map data searching means for acquiring a pedestrian map data suitable for inputting from the storage unit, and a pedestrian route searching means for searching a route for pedestrians using the data acquired, and a pedestrian map data required is acquired from the storage unit according to input instruction from the user and an information to be offered is generated. Based on the information from the pedestrian map data storage unit, it is possible to provide the user with information such as useful route information or information on adequate pedestrian route suitable for pedestrians and walking conditions and also with information such as map data of the vicinity of destination and departure point.

You are viewing the documentation for the 2.5.5 release in the 2.5.x series of releases. The latest stable release series is 2.8.x.
§Handling asynchronous results
§Make controllers asynchronous
Internally, Play Framework is asynchronous from the bottom up. Play handles every request in an asynchronous, non-blocking way.
The default configuration is tuned for asynchronous controllers. In other words, the application code should avoid blocking in controllers, i.e., having the controller code wait for an operation. Common examples of such blocking operations are JDBC calls, streaming API, HTTP requests and long computations.
Although it’s possible to increase the number of threads in the default execution context to allow more concurrent requests to be processed by blocking controllers, following the recommended approach of keeping the controllers asynchronous makes it easier to scale and to keep the system responsive under load.
§Creating non-blocking actions
Because of the way Play works, action code must be as fast as possible, i.e., non-blocking. So what should we return from our action if we are not yet able to compute the result? We should return the promise of a result!
Java 8 provides a generic promise API called CompletionStage. A CompletionStage<Result> will eventually be redeemed with a value of type Result. By using a CompletionStage<Result> instead of a normal Result, we are able to return from our action quickly without blocking anything. Play will then serve the result as soon as the promise is redeemed.
The web client will be blocked while waiting for the response, but nothing will be blocked on the server, and server resources can be used to serve other clients.
§How to create a CompletionStage<Result>
To create a CompletionStage<Result> we need another promise first: the promise that will give us the actual value we need to compute the result:
CompletionStage<Double> promiseOfPIValue = computePIAsynchronously();
CompletionStage<Result> promiseOfResult = promiseOfPIValue.thenApply(pi ->
ok("PI value computed: " + pi)
);
Play asynchronous API methods give you a CompletionStage. This is the case when you are calling an external web service using the play.libs.WS API, or if you are using Akka to schedule asynchronous tasks or to communicate with Actors using play.libs.Akka.
A simple way to execute a block of code asynchronously and to get a CompletionStage is to use the CompletableFuture.supplyAsync() helper:
CompletionStage<Integer> promiseOfInt = CompletableFuture.supplyAsync(() -> intensiveComputation());
Note: It’s important to understand which thread code runs on which promises. Here, the intensive computation will just be run on another thread.
You can’t magically turn synchronous IO into asynchronous by wrapping it in a CompletionStage. If you can’t change the application’s architecture to avoid blocking operations, at some point that operation will have to be executed, and that thread is going to block. So in addition to enclosing the operation in a CompletionStage, it’s necessary to configure it to run in a separate execution context that has been configured with enough threads to deal with the expected concurrency. See Understanding Play thread pools for more information.
It can also be helpful to use Actors for blocking operations. Actors provide a clean model for handling timeouts and failures, setting up blocking execution contexts, and managing any state that may be associated with the service. Also Actors provide patterns like ScatterGatherFirstCompletedRouter to address simultaneous cache and database requests and allow remote execution on a cluster of backend servers. But an Actor may be overkill depending on what you need.
§Using CompletionStage inside an Action
You must supply the HTTP execution context explicitly as an executor when using a Java CompletionStage inside an Action, to ensure that the HTTP.Context remains in scope. If you don’t supply the HTTP execution context, you’ll get “There is no HTTP Context available from here” errors when you call request() or other methods that depend on Http.Context.
You can supply the play.libs.concurrent.HttpExecutionContext instance through dependency injection:
public class Application extends Controller {
@Inject HttpExecutionContext ec;
public CompletionStage<Result> index() {
someCompletableFuture.supplyAsync(() -> {
// do something with request()
}, ec.current());
}
}
§Async results
We have been returning Result up until now. To send an asynchronous result our action needs to return a CompletionStage<Result>:
public CompletionStage<Result> index() {
return CompletableFuture.supplyAsync(() -> intensiveComputation())
.thenApply(i -> ok("Got result: " + i));
}
§Actions are asynchronous by default
Play actions are asynchronous by default. For instance, in the controller code below, the returned Result is internally enclosed in a promise:
public Result index() {
return ok("Got request " + request() + "!");
}
Note: Whether the action code returns a Result or a CompletionStage<Result>, both kinds of returned object are handled internally in the same way. There is a single kind of Action, which is asynchronous, and not two kinds (a synchronous one and an asynchronous one). Returning a CompletionStage is a technique for writing non-blocking code.

Lesson 6
The Pythagorean Identity (Part 2)
Lesson Narrative
This is the second of two lessons focusing on the Pythagorean Identity. The goal of this lesson is for students to deepen their understanding of the connections between \(\cos(\theta)\), \(\sin(\theta)\), and \(\tan(\theta)\) for an angle \(\theta\) on the unit circle (MP7).
The warm-up invites students to identify the sign of the three trigonometric values in each quadrant, which allows a reintroduction of tangent and a possible way to interpret the value of tangent as a slope. Students then consider how to use the value of cosine in quadrant 4 to calculate the values of sine and tangent at the same angle. This work prepares students for a card-matching activity in which they determine if particular values for cosine, sine, and tangent are possible or impossible in different quadrants. For possible matches, students practice using the Pythagorean Identity to calculate the two unknown trigonometric values. Throughout the matching process, students trade roles explaining their reasoning and critiquing the reasoning of their partner (MP3).
Learning Goals
Teacher Facing
• Critique (in writing) a strategy using the Pythagorean Identity for identifying the value of sine and tangent from the known value of cosine and the quadrant of the angle.
• Use the Pythagorean Identity to determine the value of all 3 trigonometric ratios given the value of 1 to start from and the quadrant of the angle.
Student Facing
Let’s use the Pythagorean Identity.
Learning Targets
Student Facing
• I can use the Pythagorean Identity to find the values of cosine, sine, and tangent of an angle if I know one of them and the quadrant of the angle.

Glossary Entries
• Pythagorean identity
The identity \(\sin^2(x) + \cos^2(x) = 1\) relating the sine and cosine of a number. It is called the Pythagorean identity because it follows from the Pythagorean theorem.
• period
The length of an interval at which a periodic function repeats. A function \(f\) has a period, \(p\), if \(f(x+p) = f(x)\) for all inputs \(x\).
• periodic function
A function whose values repeat at regular intervals. If \(f\) is a periodic function then there is a number \(p\), called the period, so that \(f(x + p) = f(x)\) for all inputs \(x\).
• unit circle
The circle in the coordinate plane with radius 1 and center the origin.

IntroductionEdit
HTML Yay! This is your first time ever coding a website. How exciting! But don't you want to know what importance the HTML holds? HTML is used to design web pages as simple as that. HTML is very easy to learn but it is a very powerful markup language that can control web designs. HTML together with CSS helps make web pages look beautiful. So let's start learning coding! To start off:
• Open Notepad, if you are Windows user.
• Open TextMate, if you are a Macintosh user.
There are other text editors too. At bottom is a list of recommended Text editors that can be helpful and easy to use.
Starting offEdit
To start off on the first line put <!DOCTYPE html>, this shows it is HTML code. Then put <html> on the line below to show the start of the HTML document. After that, write down </html> because this ends the HTML document.
It should look like this:
<!DOCTYPE html>
<html>
</html>
Next StepEdit
Next, in between <html> and </html> type down <head> everything you put between that and a </head> tag (tags are markups between <>). They don't appear on the pages.
It should look like this:
<!DOCTYPE html>
<html>
<head>
</head>
</html>
<body> tagsEdit
The final basic bit of structuring html is the body tag. This is simply <body> or </body>. All the code that actually shows goes between them.
It should look like this now:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
</body
</html>
SavingEdit
To save your work follow these intructions:
1. Click Save (Control + S)
2. Write the file name
3. After the filename write .html
4. So the file should look like this: filename.html
5. Click Save
(This website will look blank. For now atleast.) To know how to add things inside go to: Lesson 2>>.)

Mapping Messages: HL7 to JSON
In this article we will copy an HL7 message to an JSON document. For simplicity we will only map a few fields, but as you will see extra fields can easily be added. We placed the mapping code in Filter component, which is (usually) the most logical place for mapping code.
You can use exactly the same method to copy data between any of the different types of node trees.
These are the steps:
1. Parse the message into a source HL7 node tree structure
2. Create a JSON table tree for the target message
3. Map the data from the source node tree to the target node tree
We recommend that you type in the code for each step, but we also include complete Sample Code if you prefer to paste it in and follow along.
Tip: If you want to modify the message data see the “Transforming Messages:” tutorials in this section. Mapping and transformation use very similar techniques, the main difference is the intention: When you are mapping you are just copying the data, when you are transforming a message you are modifying the data (as well as copying it).
Create the Channel [top]
1. Create a Channel with the the following settings:
• Source = LLP Listener
• Destination = To Translator
• Channel name = Mapping HL7 to JSON
2. Activate the Filter Component: Click the Filter tab and check Use Filter.
3. Click the Add Channel button to create the channel.
Ignore the red warning messages, see resolving the milestone configuration error.
4. Open the Translator by clicking the Edit Script link at the bottom of the Filter tab.
5. Download and import the Mapping_HL7_to_JSON_Filter.zip project file.
This file contains a skeleton project and six sample HL7 messages.
6. Iguana will load the project and data into the Translator, your screen should look like this:
Tutorial Instructions [top]
1. Pass the message data to the script.
• Iguana automatically passes the message data to the main() function
• The message can be accessed using the Data parameter
• No action is needed
2. Parse the message into a convenient read-onlynode tree” structure.
Add the following line of code to your script:
3. Compare the text message and the parsed message.
Click on the Data parameter (red text) and the ADT message icon:
The messages should look something like this (we clicked on the PID segment to expand it):
4. Create the JSON outgoing message.
Add the following line of code to your script:
5. Map the HL7 node PID>Patient Identifier to the XML patient attribute id, using the :nodeValue() method to convert the node to text.
Enter this line of mapping code, auto-completion will help you to find the fields:
6. Complete the patient mapping.
Add these three lines of code:
7. Compare the incoming and outgoing messages.
Add a trace() command and click on the Msg (ADT) and Out (table) annotations to view them:
As you can see the mapping worked correctly, the patient data was mapped from the incoming to the outgoing message.
Screen Shot 2014-10-07 at 22.03.21
8. Push the outgoing message into the Iguana queue, using json.serialize() to convert the Out message into JSON formatted text:
Add the following code to your script:
Note: This is not part of the mapping process, but it is needed to forward the message to the Destination Component.
Complete Sample Code [top]
Here is the completed mapping code that you can cut and paste into your script:
local JSON_TEMPLATE = [[
{
'patients':
{
'patient-id':'',
'first-name':'',
'last-name':'',
'social-security-no':''
}
}]]
function main(Data)
-- (1) Parse the HL7 message
local Msg = hl7.parse{vmd = 'example/demo.vmd', data = Data}
-- (2) parse the JSON template
local Out = json.parse(JSON_TEMPLATE)
-- (3) Map (part of) the message
Out.patients["patient-id"] = Msg.PID[3][1][1]:nodeValue()
Out.patients["first-name"] = Msg.PID[5][1][1][1]:nodeValue()
Out.patients["last-name"] = Msg.PID[5][1][2]:nodeValue()
Out.patients["social-security-no"] = Msg.PID[19]:nodeValue()
-- (3) Push the outgoing message into the Iguana queue
queue.push(json.serialize{data=Out, compact=true})
end

Introduction
GoDoc Go Report Card
This document explains Go client for Hazelcast which uses Hazelcast's Open Client Protocol 1.6. This client works with Hazelcast 3.6 and higher.
Hazelcast is a clustering and highly scalable data distribution platform. With its various distributed data structures, distributed caching capabilities, elastic nature and more importantly with so many happy users, Hazelcast is a feature-rich, enterprise-ready and developer-friendly in-memory data grid solution.
1. Getting Started
This chapter provides information on how to get started with your Hazelcast Go client. It outlines the requirements, installation and configuration of the client, setting up a cluster, and provides a simple application that uses a distributed map in Go client.
1.1. Requirements
• Windows, Linux or MacOS
• Go 1.9 or newer
• Java 6 or newer
• Hazelcast IMDG 3.6 or newer
• Latest Hazelcast Go client
1.2. Working with Hazelcast IMDG Clusters
Hazelcast Go client requires a working Hazelcast IMDG cluster to run. This cluster handles storage and manipulation of the user data. Clients are a way to connect to the Hazelcast IMDG cluster and access such data.
Hazelcast IMDG cluster consists of one or more cluster members. These members generally run on multiple virtual or physical machines and are connected to each other via network. Any data put on the cluster is partitioned to multiple members transparent to the user. It is therefore very easy to scale the system by adding new members as the data grows. Hazelcast IMDG cluster also offers resilience. Should any hardware or software problem causes a crash to any member, the data on that member is recovered from backups and the cluster continues to operate without any downtime. Hazelcast clients are an easy way to connect to a Hazelcast IMDG cluster and perform tasks on distributed data structures that live on the cluster.
In order to use Hazelcast Go client, we first need to setup a Hazelcast IMDG cluster.
1.2.1. Setting Up a Hazelcast IMDG Cluster
There are following options to start a Hazelcast IMDG cluster easily:
• You can run standalone members by downloading and running JAR files from the website.
• You can embed members to your Java projects.
We are going to download JARs from the website and run a standalone member for this guide.
1.2.1.1. Running Standalone JARs
Follow the instructions below to create a Hazelcast IMDG cluster:
1. Go to Hazelcast's download page and download either the .zip or .tar distribution of Hazelcast IMDG.
2. Decompress the contents into any directory that you want to run members from.
3. Change into the directory that you decompressed the Hazelcast content and then into the bin directory.
4. Use either start.sh or start.bat depending on your operating system. Once you run the start script, you should see the Hazelcast IMDG logs in the terminal.
You should see a log similar to the following, which means that your 1-member cluster is ready to be used:
INFO: [192.168.0.3]:5701 [dev] [3.10.4]
Members {size:1, ver:1} [
Member [192.168.0.3]:5701 - 65dac4d1-2559-44bb-ba2e-ca41c56eedd6 this
]
Sep 06, 2018 10:50:23 AM com.hazelcast.core.LifecycleService
INFO: [192.168.0.3]:5701 [dev] [3.10.4] [192.168.0.3]:5701 is STARTED
1.2.1.2. Adding User Library to CLASSPATH
When you want to use features such as querying and language interoperability, you might need to add your own Java classes to the Hazelcast member in order to use them from your Go client. This can be done by adding your own compiled code to the CLASSPATH. To do this, compile your code with the CLASSPATH and add the compiled files to the user-lib directory in the extracted hazelcast-<version>.zip (or tar). Then, you can start your Hazelcast member by using the start scripts in the bin directory. The start scripts will automatically add your compiled classes to the CLASSPATH.
Note that if you are adding an IdentifiedDataSerializable or a Portable class, you need to add its factory too. Then, you should configure the factory in the hazelcast.xml configuration file. This file resides in the bin directory where you extracted the hazelcast-<version>.zip (or tar).
The following is an example configuration when you are adding an IdentifiedDataSerializable class:
<hazelcast>
...
<serialization>
<data-serializable-factories>
<data-serializable-factory factory-id=<identified-factory-id>>
IdentifiedFactoryClassName
</data-serializable-factory>
</data-serializable-factories>
</serialization>
...
</hazelcast>
If you want to add a Portable class, you should use <portable-factories> instead of <data-serializable-factories> in the above configuration.
See the Hazelcast IMDG Reference Manual for more information on setting up the clusters.
1.3. Downloading and Installing
Following command installs Hazelcast Go client:
go get github.com/hazelcast/hazelcast-go-client
See the Go client's tutorial for more information on installing and setting up the client.
1.4. Basic Configuration
If you are using Hazelcast IMDG and Go client on the same computer, generally the default configuration should be fine. This is great for trying out the client. However, if you run the client on a different computer than any of the cluster members, you may need to do some simple configuration such as specifying the member addresses.
The Hazelcast IMDG members and clients have their own configuration options. You may need to reflect some of the member side configurations on the client side to properly connect to the cluster. This section describes the most common configuration elements to get you started in no time. It discusses some member side configuration options to ease the understanding of Hazelcast's ecosystem. Then, the client side configuration options regarding the cluster connection are discussed. The configurations for the Hazelcast IMDG data structures that can be used in the Node.js client are discussed in the following sections.
See the Hazelcast IMDG Reference Manual and Configuration Overview section for more information.
1.4.1. Configuring Hazelcast IMDG
Hazelcast IMDG aims to run out of the box for most common scenarios. However if you have limitations on your network such as multicast being disabled, you may have to configure your Hazelcast IMDG members so that they can find each other on the network. Also, since most of the distributed data structures are configurable, you may want to configure them according to your needs. We will show you the basics about network configuration here.
You can use the following options to configure Hazelcast IMDG:
• Using the hazelcast.xml configuration file.
• Programmatically configuring the member before starting it from the Java code.
Since we use standalone servers, we will use the hazelcast.xml file to configure our cluster members.
When you download and unzip hazelcast-<version>.zip (or tar), you see the hazelcast.xml in the bin directory. When a Hazelcast member starts, it looks for the hazelcast.xml file to load the configuration from. A sample hazelcast.xml is shown below.
<hazelcast>
<group>
<name>dev</name>
<password>dev-pass</password>
</group>
<network>
<port auto-increment="true" port-count="100">5701</port>
<join>
<multicast enabled="true">
<multicast-group>224.2.2.3</multicast-group>
<multicast-port>54327</multicast-port>
</multicast>
<tcp-ip enabled="false">
<interface>127.0.0.1</interface>
<member-list>
<member>127.0.0.1</member>
</member-list>
</tcp-ip>
</join>
<ssl enabled="false"/>
</network>
<partition-group enabled="false"/>
<map name="default">
<backup-count>1</backup-count>
</map>
</hazelcast>
We will go over some important configuration elements in the rest of this section.
• <group>: Specifies which cluster this member belongs to. A member connects only to the other members that are in the same group as itself. As shown in the above configuration sample, there are <name> and <password> tags under the <group> element with some pre-configured values. You may give your clusters different names so that they can live in the same network without disturbing each other. Note that the cluster name should be the same across all members and clients that belong to the same cluster. The <password> tag is not in use since Hazelcast 3.9. It is there for backward compatibility purposes. You can remove or leave it as it is if you use Hazelcast 3.9 or later.
• <network>
• <port>: Specifies the port number to be used by the member when it starts. Its default value is 5701. You can specify another port number, and if you set auto-increment to true, then Hazelcast will try the subsequent ports until it finds an available port or the port-count is reached.
• <join>: Specifies the strategies to be used by the member to find other cluster members. Choose which strategy you want to use by setting its enabled attribute to true and the others to false.
• <multicast>: Members find each other by sending multicast requests to the specified address and port. It is very useful if IP addresses of the members are not static.
• <tcp>: This strategy uses a pre-configured list of known members to find an already existing cluster. It is enough for a member to find only one cluster member to connect to the cluster. The rest of the member list is automatically retrieved from that member. We recommend putting multiple known member addresses there to avoid disconnectivity should one of the members in the list is unavailable at the time of connection.
These configuration elements are enough for most connection scenarios. Now we will move onto the configuration of the Go client.
1.4.2. Configuring Hazelcast Go Client
This section describes some network configuration settings to cover common use cases in connecting the client to a cluster. Refer to Configuration Overview and the following sections for information about detailed network configuration and/or additional features of Hazelcast Go client configuration.
An easy way to configure your Hazelcast Go client is to create a Config object and set the appropriate options. Then you can supply this object to your client at the startup.
Configuration
You need to create a Config object and adjust its properties. Then you can pass this object to the client when starting it.
package main
import "github.com/hazelcast/hazelcast-go-client"
func main() {
config := hazelcast.NewConfig()
client , _ := hazelcast.NewClientWithConfig(config)
}
If you run the Hazelcast IMDG members in a different server than the client, you most probably have configured the members' ports and cluster names as explained in the previous section. If you did, then you need to make certain changes to the network settings of your client.
1.4.2.1. Group Settings
You need to provide the group name of the cluster, if it is defined on the server side, to which you want the client to connect.
config := hazelcast.NewConfig()
config.GroupConfig().SetName("GROUP_NAME_OF_YOUR_CLUSTER")
NOTE: If you have a Hazelcast IMDG release older than 3.11, you need to provide also a group password along with the group name.
1.4.2.2. Network Settings
You need to provide the IP address and port of at least one member in your cluster so the client can find it.
config := hazelcast.NewConfig()
config.NetworkConfig().AddAddress("some-ip-address:port")
hazelcast.NewClientWithConfig(config)
1.4.3. Client System Properties
While configuring your Go client, you can use various system properties provided by Hazelcast to tune its clients. These properties can be set programmatically through config.SetProperty or by using an environment variable. The value of this property will be:
• the programmatically configured value, if programmatically set,
• the environment variable value, if the environment variable is set,
• the default value, if none of the above is set.
See the following for an example client system property:
InvocationTimeoutSeconds = NewHazelcastPropertyInt64WithTimeUnit("hazelcast.client.invocation.timeout.seconds",
120, time.Second)
The above property specifies the timeout duration to give up the invocations when a member in the member list is not reachable, and its default value is 120 seconds. You can change this value programmatically or using an environment variable, as shown below.
Programmatically:
config.SetProperty(property.InvocationTimeoutSeconds.Name(), "2") // Sets invocation timeout as 2 seconds
or
config.SetProperty("hazelcast.client.invocation.timeout.seconds", "2") // Sets invocation timeout as 2 seconds
By using an environment variable:
os.Setenv(property.InvocationTimeoutSeconds.Name(), "2")
If you set a property both programmatically and via an environment variable, the programmatically set value will be used.
See the complete list of client system properties, along with their descriptions, which can be used to configure your Hazelcast Go client.
1.5. Basic Usage
Now that we have a working cluster and we know how to configure both our cluster and client, we can run a simple program to use a distributed map in the Go client.
The following example first creates a programmatic configuration object. Then, it starts a client.
import (
"fmt"
"github.com/hazelcast/hazelcast-go-client"
)
func main() {
config := hazelcast.NewConfig() // We create a config for illustrative purposes.
// We do not adjust this config. Therefore it has default settings.
client, err := hazelcast.NewClientWithConfig(config)
if err != nil {
fmt.Println(err)
return
}
fmt.Println(client.Name()) // Connects and prints the name of the client
}
This should print logs about the cluster members and information about the client itself such as the client type, UUID and address.

For programmatic configuration of the Hazelcast Go client, just instantiate a Config object and configure the desired aspects. An example is shown below.
config := hazelcast.NewConfig()
config.NetworkConfig().AddAddress("some-ip-address:port")
hazelcast.NewClientWithConfig(config)
See the Config class documentation at Hazelcast Go client API Docs for details.
4. Serialization
Serialization is the process of converting an object into a stream of bytes to store the object in the memory, a file or database, or transmit it through the network. Its main purpose is to save the state of an object in order to be able to recreate it when needed. The reverse process is called deserialization. Hazelcast offers you its own native serialization methods. You will see these methods throughout this chapter. For primitive types, it uses Hazelcast native serialization. For other complex types (e.g. Go objects), it uses Gob serialization.
NOTE: int and []int types in Go Language are serialized as int64 and []int64 respectively by Hazelcast Serialization.
Note that if the object is not one of the above-mentioned types, the Go client uses Gob serialization by default.
However, Gob Serialization is not the best way of serialization in terms of performance and interoperability between the clients in different languages. If you want the serialization to work faster or you use the clients in different languages, Hazelcast offers its own native serialization types, such as IdentifiedDataSerializable Serialization and Portable Serialization.
On top of all, if you want to use your own serialization type, you can use a Custom Serialization.
4.1. IdentifiedDataSerializable Serialization
For a faster serialization of objects, Hazelcast recommends to implement IdentifiedDataSerializable interface.
The following is an example of an object implementing this interface:
const (
employeeClassID = 100
sampleDataSerializableFactoryID = 1000
)
type Employee struct {
id int32
name string
}
func (e *Employee) ClassID() int32 {
return employeeClassID
}
func (e *Employee) FactoryID() int32 {
return sampleDataSerializableFactoryID
}
func (e *Employee) ReadData(input serialization.DataInput) error {
e.id = input.ReadInt32()
e.name = input.ReadUTF()
return input.Error()
}
func (e *Employee) WriteData(output serialization.DataOutput) (err error) {
output.WriteInt32(e.id)
output.WriteUTF(e.name)
return
}
The IdentifiedDataSerializable interface uses ClassID and FactoryID to reconstitute the object. To complete the implementation IdentifiedDataSerializableFactory should also be implemented and registered into SerializationConfig which can be accessed from config.SerializationConfig(). The factory's responsibility is to return an instance of the right IdentifiedDataSerializable object, given the classID.
A sample IdentifiedDataSerializableFactory could be implemented as follows:
type SampleDataSerializableFactory struct {
}
func (*SampleDataSerializableFactory) Create(classID int32) serialization.IdentifiedDataSerializable {
if classID == employeeClassID {
return &Employee{}
}
return nil
}
The last step is to register the IdentifiedDataSerializableFactory to the SerializationConfig.
config := hazelcast.NewConfig()
config.SerializationConfig().AddDataSerializableFactory(sampleDataSerializableFactoryID, SampleDataSerializableFactory{})
Note that the ID that is passed to the SerializationConfig is same as the FactoryID that the address object returns.
4.2. Portable Serialization
As an alternative to the existing serialization methods, Hazelcast offers portable serialization. To use it, you need to implement the Portable interface. Portable serialization has the following advantages:
• Supporting multiversion of the same object type.
• Fetching individual fields without having to rely on the reflection.
• Querying and indexing support without deserialization and/or reflection.
In order to support these features, a serialized Portable object contains meta information like the version and the concrete location of the each field in the binary data. This way Hazelcast is able to navigate in the binary data and deserialize only the required field without actually deserializing the whole object which improves the query performance.
With multiversion support, you can have two members where each of them having different versions of the same object, and Hazelcast will store both meta information and use the correct one to serialize and deserialize portable objects depending on the member. This is very helpful when you are doing a rolling upgrade without shutting down the cluster.
Also note that portable serialization is totally language independent and is used as the binary protocol between Hazelcast server and clients.
A sample portable implementation of a Foo class looks like the following:
const (
customerClassID = 1
samplePortableFactoryID = 1
)
type Customer struct {
name string
id int32
lastOrder time.Time
}
func (c *Customer) FactoryID() int32 {
return samplePortableFactoryID
}
func (c *Customer) ClassID() int32 {
return customerClassID
}
func (c *Customer) WritePortable(writer serialization.PortableWriter) (err error) {
writer.WriteInt32("id", c.id)
writer.WriteUTF("name", c.name)
writer.WriteInt64("lastOrder", c.lastOrder.UnixNano()/int64(time.Millisecond))
return
}
func (c *Customer) ReadPortable(reader serialization.PortableReader) (err error) {
c.id = reader.ReadInt32("id")
c.name = reader.ReadUTF("name")
t := reader.ReadInt64("lastOrder")
c.lastOrder = time.Unix(0, t*int64(time.Millisecond))
return reader.Error()
}
Similar to IdentifiedDataSerializable, a Portable object must provide ClassID and FactoryID . The factory object will be used to create the Portable object given the classId.
A sample PortableFactory could be implemented as follows:
type SamplePortableFactory struct {
}
func (pf *SamplePortableFactory) Create(classID int32) serialization.Portable {
if classID == customerClassID {
return &Customer{}
}
return nil
}
The last step is to register the PortableFactory to the SerializationConfig.
config := hazelcast.NewConfig()
config.SerializationConfig().AddPortableFactory(samplePortableFactoryID, &SamplePortableFactory{})
Note that the ID that is passed to the SerializationConfig is same as the FactoryID that Foo object returns.
4.3. Custom Serialization
Hazelcast lets you plug a custom serializer to be used for serialization of objects.
Let's say you have an object CustomSerializable and you would like to customize the serialization, since you may want to use an external serializer for only one object.
type CustomSerializable struct {
value string
}
Let's say your custom CustomSerializer will serialize CustomSerializable.
type CustomSerializer struct {
}
func (s *CustomSerializer) ID() int32 {
return 10
}
func (s *CustomSerializer) Read(input serialization.DataInput) (obj interface{}, err error) {
array = input.ReadByteArray()
return &CustomSerializable{string(array)}, input.Error()
}
func (s *CustomSerializer) Write(output serialization.DataOutput, obj interface{}) (err error) {
array := []byte(obj.(CustomSerializable).value)
output.WriteByteArray(array)
return
}
Note that the serializer id must be unique as Hazelcast will use it to lookup the CustomSerializer while it deserializes the object. Now the last required step is to register the MusicianSerializer to the configuration.
musicianSerializer := &MusicianSerializer{}
config.SerializationConfig().AddCustomSerializer(reflect.TypeOf((*CustomSerializable)(nil)), &CustomSerializer{})
From now on, Hazelcast will use CustomSerializer to serialize CustomSerializable objects.
4.4. JSON Serialization
You can use the JSON formatted strings as objects in Hazelcast cluster. Starting with Hazelcast IMDG 3.12, the JSON serialization is one of the formerly supported serialization methods. Creating JSON objects in the cluster does not require any server side coding and hence you can just send a JSON formatted string object to the cluster and query these objects by fields.
In order to use JSON serialization, you should use the HazelcastJSONValue object for the key or value.
You can construct a HazelcastJSONValue from string or from your go object:
//from string
core.CreateHazelcastJSONValueFromString{"your json string"}
//from go object
core.CreateHazelcastJSONValueFromString{yourObject}
No JSON parsing is performed but it is your responsibility to provide correctly formatted JSON strings. The client will not validate the string, and it will send it to the cluster as it is. If you submit incorrectly formatted JSON strings and, later, if you query those objects, it is highly possible that you will get formatting errors since the server will fail to deserialize or find the query fields.
Here is an example of how you can construct a HazelcastJSONValue and put to the map:
jsonValue1 , _ := core.CreateHazelcastJSONValueFromString("{ \"age\": 4 }")
mp.Put("item1", jsonValue1)
jsonValue2 , _ := core.CreateHazelcastJSONValueFromString("{ \"age\": 4 }")
mp.Put("item2", jsonValue2)
You can query JSON objects in the cluster using the Predicates of your choice. An example JSON query for querying the values whose age is greater than 6 is shown below:
// Get the objects whose age is greater than 6
result, _ := mp.ValuesWithPredicate(predicate.GreaterThan("age", 6))
var person interface{}
result[0].(*core.HazelcastJSON).Unmarshal(&person)
log.Println("Retrieved: ", len(result))
log.Println("Entry is: ", person)
Note that we have used var person interface{}. If we already knew the type of our object we could do the following:
type person struct {
Age int
Name string
}
person1 , _ := core.CreateHazelcastJSONValue(person{Age: 20, Name: "Walter"})
person2 , _ := core.CreateHazelcastJSONValue(person{Age: 5, Name: "Mike"})
mp.Put("item1", person1)
mp.Put("item2", person2)
result, _ := mp.ValuesWithPredicate(predicate.GreaterThan("Age", 6))
var person person
value := result[0].(*core.HazelcastJSON)
log.Println(value.ToString()) //{"Age":20,"Name":"Walter"}
value.Unmarshal(&person)
log.Println("Retrieved: ", len(result)) // Retrieved: 1
log.Println("Entry is: ", person) // Entry is: {20 Walter}
Note that here we also show an example of how to create the JSON value from a go object.
4.5. Global Serialization
The global serializer is identical to custom serializers from the implementation perspective. The global serializer is registered as a fallback serializer to handle all other objects if a serializer cannot be located for them.
By default, Gob serialization is used if the object is not IdentifiedDataSerializable or Portable or there is no custom serializer for it. When you configure a global serializer, it is used instead of Gob serialization.
Use cases:
• Third party serialization frameworks can be integrated using the global serializer.
• For your custom objects, you can implement a single serializer to handle all of them.
A sample global serializer that integrates with a third party serializer is shown below.
type GlobalSerializer struct {
}
func (*GlobalSerializer) ID() int32 {
return 20
}
func (*GlobalSerializer) Read(input serialization.DataInput) (obj interface{}, err error) {
// return MyFavoriteSerializer.deserialize(input)
return
}
func (*GlobalSerializer) Write(output serialization.DataOutput, object interface{}) (err error) {
// output.write(MyFavoriteSerializer.serialize(object))
return
}
You should register the global serializer in the configuration.
config.SerializationConfig().SetGlobalSerializer(&GlobalSerializer{})
5. Setting Up Client Network
All network related configuration of Hazelcast Go client is performed via the NetworkConfig class when using programmatic configuration. Here is an example of configuring network for Go client programmatically.
config := hazelcast.NewConfig()
networkConfig := config.NetworkConfig()
networkConfig.AddAddress("10.1.1.21", "10.1.1.22:5703")
networkConfig.SetSmartRouting(true)
networkConfig.SetRedoOperation(true)
networkConfig.SetConnectionTimeout(6 * time.Second)
networkConfig.SetConnectionAttemptPeriod(5 * time.Second)
networkConfig.SetConnectionAttemptLimit(5)
5.1. Providing the Member Addresses
Address list is the initial list of cluster addresses which the client will connect to. The client uses this list to find an alive member. Although it may be enough to give only one address of a member in the cluster (since all members communicate with each other), it is recommended that you give the addresses for all the members.
config := hazelcast.NewConfig()
networkConfig := config.NetworkConfig()
networkConfig.AddAddress("10.1.1.21", "10.1.1.22:5703")
If the port part is omitted, then 5701, 5702 and 5703 will be tried in a random order.
You can specify multiple addresses with or without the port information as seen above. The provided list is shuffled and tried in a random order. Its default value is localhost.
5.2. Setting Smart Routing
Smart routing defines whether the client mode is smart or unisocket. See the Go client Operation Modes section for the description of smart and unisocket modes.
The following are example configurations.
config := hazelcast.NewConfig()
networkConfig := config.NetworkConfig()
networkConfig.SetSmartRouting(true)
Its default value is true (smart client mode).
5.3. Enabling Redo Operation
It enables/disables redo-able operations. While sending the requests to the related members, the operations can fail due to various reasons. Read-only operations are retried by default. If you want to enable retry for the other operations, you can set the redoOperation to true.
config := hazelcast.NewConfig()
networkConfig := config.NetworkConfig()
networkConfig.SetRedoOperation(true)
Its default value is false (disabled).
5.4. Setting Connection Timeout
Connection timeout is the timeout value in milliseconds for the members to accept the client connection requests. If the member does not respond within the timeout, the client will retry to connect as many as NetworkConfig.connectionAttemptLimit times.
The following are the example configurations.
config := hazelcast.NewConfig()
networkConfig := config.NetworkConfig()
networkConfig.SetConnectionTimeout(6 * time.Second)
Its default value is 5000 milliseconds.
5.5. Setting Connection Attempt Limit
While the client is trying to connect initially to one of the members in the NetworkConfig.addresses, that member might not be available at that moment. Instead of giving up, throwing an error and stopping the client, the client will retry as many as NetworkConfig.connectionAttemptLimit times. This is also the case when the previously established connection between the client and that member goes down.
The following are example configurations.
config := hazelcast.NewConfig()
networkConfig := config.NetworkConfig()
networkConfig.SetConnectionAttemptLimit(5)
Its default value is 2.
5.6. Setting Connection Attempt Period
Connection attempt period is the duration in milliseconds between the connection attempts.
The following are example configurations.
config := hazelcast.NewConfig()
networkConfig := config.NetworkConfig()
networkConfig.SetConnectionAttemptPeriod(5 * time.Second)
Its default value is 3000 milliseconds.
5.7. Enabling Client TLS/SSL
You can use TLS/SSL to secure the connection between the clients and members. If you want to enable TLS/SSL for the client-cluster connection, you should set an SSL configuration. Please see TLS/SSL section.
As explained in the TLS/SSL section, Hazelcast members have key stores used to identify themselves (to other members) and Hazelcast Go clients have certificate authorities used to define which members they can trust. Hazelcast has the mutual authentication feature which allows the Go clients also to have their private keys and public certificates and members to have their certificate authorities so that the members can know which clients they can trust. See the Mutual Authentication section.
5.8. Enabling Hazelcast Cloud Discovery
The purpose of Hazelcast Cloud Discovery is to provide the clients to use IP addresses provided by hazelcast orchestrator. To enable Hazelcast Cloud Discovery, specify a token for the discoveryToken field and set the enabled field to true.
The following are example configurations.
config.GroupConfig().SetName("hazel")
config.GroupConfig().SetPassword("cast")
cloudConfig := config.NetworkConfig().CloudConfig()
cloudConfig.SetDiscoveryToken("EXAMPLE_TOKEN")
cloudConfig.SetEnabled(true)
To be able to connect to the provided IP addresses, you should use secure TLS/SSL connection between the client and members. Therefore, you should set an SSL configuration as described in the previous section.
6. Securing Client Connection
This chapter describes the security features of Hazelcast Go client. These include using TLS/SSL for connections between members and between clients and members, and mutual authentication. These security features require Hazelcast IMDG Enterprise edition.
6.1. TLS/SSL
One of the offers of Hazelcast is the TLS/SSL protocol which you can use to establish an encrypted communication across your cluster with key stores and trust stores.
• A Java keyStore is a file that includes a private key and a public certificate. The equivalent of a key store is the combination of key and cert files at the Go client side.
• A Java trustStore is a file that includes a list of certificates trusted by your application which is named certificate authority. The equivalent of a trust store is a ca file at the Go client side.
You should set keyStore and trustStore before starting the members. See the next section how to set keyStore and trustStore on the server side.
6.1.1. TLS/SSL for Hazelcast Members
Hazelcast allows you to encrypt socket level communication between Hazelcast members and between Hazelcast clients and members, for end to end encryption. To use it, see the TLS/SSL for Hazelcast Members section in the Hazelcast IMDG Reference Manual.
6.1.2. TLS/SSL for Hazelcast Go clients
Hazelcast Go clients which support TLS/SSL should have the following user supplied SSLConfig
config := hazelcast.NewConfig()
sslConfig := config.NetworkConfig().SSLConfig()
sslConfig.SetEnabled(true)
sslConfig.SetCaPath("yourCaPath")
sslConfig.ServerName="serverName"
6.1.3. Mutual Authentication
As explained above, Hazelcast members have key stores used to identify themselves (to other members) and Hazelcast clients have trust stores used to define which members they can trust.
Using mutual authentication, the clients also have their key stores and members have their trust stores so that the members can know which clients they can trust to.
To enable mutual authentication, firstly, you need to set the following property on the server side in the hazelcast.xml:
<network>
<ssl enabled="true">
<properties>
<property name="javax.net.ssl.mutualAuthentication">REQUIRED</property>
</properties>
</ssl>
</network>
You can see the details of setting mutual authentication on the server side in the Mutual Authentication section of the Hazelcast IMDG Reference Manual.
Client side config needs to be set as follows:
config := hazelcast.NewConfig()
sslConfig := config.NetworkConfig().SSLConfig()
sslConfig.SetEnabled(true)
sslConfig.SetCaPath("yourCaPath")
sslConfig.AddClientCertAndKeyPath("yourClientCertPath", "yourClientKeyPath")
sslConfig.ServerName = "yourServerName"
7. Using Go Client with Hazelcast IMDG
This chapter provides information on how you can use Hazelcast IMDG's data structures in the Go client, after giving some basic information including an overview to the client API, operation modes of the client and how it handles the failures.
7.1. Go Client API Overview
If you are ready to go, let's start to use Hazelcast Go client!
The first step is configuration. You can configure the Go client programmatically.
config := hazelcast.NewConfig()
config.GroupConfig().SetName("dev")
config.GroupConfig().SetPassword("pass")
config.NetworkConfig().AddAddress("10.1.1.21", "10.1.1.22:5703")
The second step is initializing the HazelcastClient to be connected to the cluster.
client, err := hazelcast.NewClientWithConfig(config)
This client object is your gateway to access all Hazelcast distributed objects.
Let’s create a map and populate it with some data, as shown below.
client, err := hazelcast.NewClientWithConfig(config)
if err != nil {
fmt.Println(err)
return
}
personnelMap, _ := client.GetMap("personnelMap")
personnelMap.Put("Denise", "Sales")
personnelMap.Put("Erwin", "Sales")
personnelMap.Put("Faith", "Sales")
As the final step, if you are done with your client, you can shut it down as shown below. This will release all the used resources and will close connections to the cluster.
client.Shutdown()
7.2. Go Client Operation Modes
The client has two operation modes because of the distributed nature of the data and cluster: smart and unisocket.
7.2.1. Smart Client
In the smart mode, clients connect to each cluster member. Since each data partition uses the well known and consistent hashing algorithm, each client can send an operation to the relevant cluster member, which increases the overall throughput and efficiency. Smart mode is the default mode.
7.2.2. Unisocket Client
For some cases, the clients can be required to connect to a single member instead of each member in the cluster. Firewalls, security or some custom networking issues can be the reason for these cases.
In the unisocket client mode, the client will only connect to one of the configured addresses. This single member will behave as a gateway to the other members. For any operation requested from the client, it will redirect the request to the relevant member and return the response back to the client returned from this member.
7.3. Handling Failures
There are two main failure cases you should be aware of. Below sections explain these and the configurations you can perform to achieve proper behavior.
7.3.1. Handling Client Connection Failure
While the client is trying to connect initially to one of the members in the NetworkConfig.SetAddresses, all the members might not be available. Instead of giving up, returning an error and stopping the client, the client will retry as many times as connectionAttemptLimit.
You can configure connectionAttemptLimit for the number of times you want the client to retry connecting. See the Setting Connection Attempt Limit section.
The client executes each operation through the already established connection to the cluster. If this connection(s) disconnects or drops, the client will try to reconnect as configured.
7.3.2. Handling Retry-able Operation Failure
While sending the requests to the related members, the operations can fail due to various reasons. Read-only operations are retried by default. If you want to enable retrying for the other operations, you can set the redoOperation to true. See Enabling Redo Operation section.
You can set a timeout for retrying the operations sent to a member. This can be provided by using the property hazelcast.client.invocation.timeout.seconds in config.SetProperty. The client will retry an operation within this given period, of course, if it is a read-only operation or you enabled the redoOperation as stated in the above paragraph. This timeout value is important when there is a failure resulted by either of the following causes:
• Member throws an exception.
• Connection between the client and member is closed.
• Client’s heartbeat requests are timed out.
When a connection problem occurs, an operation is retried if it is certain that it has not run on the member yet or if it is idempotent such as a read-only operation, i.e., retrying does not have a side effect. If it is not certain whether the operation has run on the member, then the non-idempotent operations are not retried. However, as explained in the first paragraph of this section, you can force all client operations to be retried (redoOperation) when there is a connection failure between the client and member. But in this case, you should know that some operations may run multiple times causing conflicts. For example, assume that your client sent a queue.offer operation to the member and then the connection is lost. Since there will be no response for this operation, you will not know whether it has run on the member or not. If you enabled redoOperation, it means this operation may run again, which may cause two instances of the same object in the queue.
When invocation is being retried, the client may wait some time before it retries again. You can configure this duration for waiting using the following property:
config.setProperty(“hazelcast.client.invocation.retry.pause.millis”, “500");
The default retry wait time is 1 second.
7.4. Using Distributed Data Structures
Most of the distributed data structures are supported by the Go client. In this chapter, you will learn how to use these distributed data structures.
7.4.1. Using Map
Hazelcast Map (IMap) is a distributed map. Through the Go client, you can perform operations like reading and writing from/to a Hazelcast Map with the well known get and put methods. For details, see the Map section in the Hazelcast IMDG Reference Manual.
A Map usage example is shown below.
// Get the Distributed Map from Cluster.
mp, _ := hz.GetMap("myDistributedMap")
//Standard Put and Get.
mp.Put("key", "value")
mp.Get("key")
//Concurrent Map methods, optimistic updating
mp.PutIfAbsent("somekey", "somevalue")
mp.ReplaceIfSame("key", "value", "newvalue")
7.4.2. Using MultiMap
Hazelcast MultiMap is a distributed and specialized map where you can store multiple values under a single key. For details, see the MultiMap section in the Hazelcast IMDG Reference Manual.
A MultiMap usage example is shown below.
// Get the Distributed MultiMap from Cluster.
multiMap, _ := hz.GetMultiMap("myDistributedMultimap")
// Put values in the map against the same key
multiMap.Put("my-key", "value1")
multiMap.Put("my-key", "value2")
multiMap.Put("my-key", "value3")
// Print out all the values for associated with key called "my-key"
values, _ := multiMap.Get("my-key")
fmt.Println(values)
// remove specific key/value pair
multiMap.Remove("my-key", "value2")
7.4.3. Using Replicated Map
Hazelcast ReplicatedMap is a distributed key-value data structure where the data is replicated to all members in the cluster. It provides full replication of entries to all members for high speed access. For details, see the Replicated Map section in the Hazelcast IMDG Reference Manual.
A Replicated Map usage example is shown below.
// Get a Replicated Map called "my-replicated-map"
mp, _ := hz.GetReplicatedMap("my-replicated-map")
// Put and Get a value from the Replicated Map
replacedValue, _ := mp.Put("key", "value") // key/value replicated to all members
fmt.Println("replacedValue = ", replacedValue) // Will be null as its first update
value, _ := mp.Get("key") // the value is retrieved from a random member in the cluster
fmt.Println("value for key = ", value)
7.4.4. Using Queue
Hazelcast Queue(IQueue) is a distributed queue which enables all cluster members to interact with it. For details, see the Queue section in the Hazelcast IMDG Reference Manual.
A Queue usage example is shown below.
// Get a Blocking Queue called "my-distributed-queue"
queue, _ := hz.GetQueue("my-distributed-queue")
// Offer a String into the Distributed Queue
queue.Offer("item")
// Poll the Distributed Queue and return the String
queue.Poll()
//Timed blocking Operations
queue.OfferWithTimeout("anotheritem", 500*time.Millisecond)
queue.PollWithTimeout(5 * time.Second)
//Indefinitely blocking Operations
queue.Put("yetanotheritem")
fmt.Println(queue.Take())
7.4.5. Using Set
Hazelcast Set(ISet) is a distributed set which does not allow duplicate elements. For details, see the Set section in the Hazelcast IMDG Reference Manual.
A Set usage example is shown below.
// Get the distributed set from cluster
set, _ := hz.GetSet("my-distributed-set")
// Add items to the set with duplicates
set.Add("item1")
set.Add("item1")
set.Add("item2")
set.Add("item2")
set.Add("item3")
set.Add("item3")
// Get the items. Note that no duplicates
items, _ := set.ToSlice()
fmt.Println(items)
7.4.6. Using List
Hazelcast List(IList) is distributed list which allows duplicate elements and preserves the order of elements. For details, see the List section in the Hazelcast IMDG Reference Manual.
A List usage example is shown below.
// Get the distributed list from cluster
list, _ := hz.GetList("my-distributed-list")
// Add elements to the list
list.Add("item1")
list.Add("item2")
// Remove the first element
removed, _ := list.RemoveAt(0)
fmt.Println("removed: ", removed)
// There is only one element left
size, _ := list.Size()
fmt.Println("current size is: ", size)
7.4.7. Using Ringbuffer
Hazelcast Ringbuffer is a replicated but not partitioned data structure that stores its data in a ring-like structure. You can think of it as a circular array with a given capacity. Each Ringbuffer has a tail and a head. The tail is where the items are added and the head is where the items are overwritten or expired. You can reach each element in a Ringbuffer using a sequence ID, which is mapped to the elements between the head and tail (inclusive) of the Ringbuffer. For details, see the Ringbuffer section in the Hazelcast IMDG Reference Manual.
A Ringbuffer usage example is shown below.
rb, _ := hz.GetRingbuffer("rb")
// we start from the oldest item.
// if you want to start from the next item, call rb.tailSequence()+1
// add two items into ring buffer
rb.Add(100, core.OverflowPolicyOverwrite)
rb.Add(200, core.OverflowPolicyOverwrite)
// we start from the oldest item.
// if you want to start from the next item, call rb.tailSequence()+1
sequence, _ := rb.HeadSequence()
fmt.Println(rb.ReadOne(sequence))
sequence++
fmt.Println(rb.ReadOne(sequence))
7.4.8. Using Reliable Topic
Hazelcast ReliableTopic is a distributed topic implementation backed up by the Ringbuffer data structure. For details, see the Reliable Topic section in the Hazelcast IMDG Reference Manual.
A Reliable Topic usage example is shown below.
reliableTopic, _ := client.GetReliableTopic("myReliableTopic")
reliableTopic.AddMessageListener(&reliableTopicMessageListener{})
for i := 0; i < 10; i++ {
reliableTopic.Publish("Message " + strconv.Itoa(i))
}
7.4.9. Using PN Counter
Hazelcast PNCounter (Positive-Negative Counter) is a CRDT positive-negative counter implementation. It is an eventually consistent counter given there is no member failure. For details, see the PN Counter section in the Hazelcast IMDG Reference Manual.
A PN Counter usage example is shown below.
counter, _ := client.GpetPNCounter("myPNCounter")
currentValue, _ := counter.AddAndGet(5)
fmt.Printf("added 5 counter, current value is %d\n", currentValue)
currentValue, _ = counter.DecrementAndGet()
fmt.Printf("decremented counter, current value is %d\n", currentValue)
7.4.10. Using Flake ID Generator
Hazelcast FlakeIdGenerator is used to generate cluster-wide unique identifiers. Generated identifiers are long primitive values and are k-ordered (roughly ordered). IDs are in the range from 0 to 2^63-1 (maximum signed long value). For details, see theFlakeIdGenerator section in the Hazelcast IMDG Reference Manual.
A Flake ID Generator usage example is shown below.
flakeIDGenerator, _ := client.GetFlakeIDGenerator("generator")
id, _ := flakeIDGenerator.NewID()
fmt.Printf("new id : %d", id)
7.5. Distributed Events
This chapter explains when various events are fired and describes how you can add event listeners on a Hazelcast Go client. These events can be categorized as cluster and distributed data structure events.
7.5.1. Cluster Events
You can add event listeners to a Hazelcast Go client. You can configure the following listeners to listen to the events on the client side.
• Membership Listener: Notifies when a member joins to/leaves the cluster, or when an attribute is changed in a member.
• Distributed Object Listener: Notifies when a distributed object is created or destroyed throughout the cluster.
• Lifecycle Listener: Notifies when the client is starting, started, shutting down, and shutdown.
7.5.1.1. Listening for Member Events
You can add the following types of member events to the ClusterService.
• memberAdded: A new member is added to the cluster.
• memberRemoved: An existing member leaves the cluster.
The following is a membership listener registration by using client.Cluster().AddMembershipListener(&membershipListener{}) function.
type membershipListener struct {
}
func (l *membershipListener) MemberAdded(member core.Member) {
fmt.Println("New member joined: ", member)
}
func (l *membershipListener) MemberRemoved(member core.Member) {
fmt.Println("Member left: ", member)
}
7.5.1.2. Listening for Lifecycle Events
The Lifecycle Listener notifies for the following events:
• STARTING: The client is starting.
• STARTED: The client has started.
• SHUTTING_DOWN: The client is shutting down.
• SHUTDOWN: The client’s shutdown has completed.
• CONNECTED: The client is connected to cluster
• DISCONNECTED: The client is disconnected from cluster note that this does not imply shutdown
The following is an example of Lifecycle Listener that is added to config and its output.
type lifecycleListener struct {
}
func (l *lifecycleListener) LifecycleStateChanged(newState string) {
fmt.Println("Lifecycle Event >>> ", newState)
}
config.AddLifecycleListener(&lifecycleListener{})
Or it can be added later after client has started
registrationID := client.LifecycleService().AddLifecycleListener(&lifecycleListener{})
// Unregister it when you want to stop listening
client.LifecycleService().RemoveLifecycleListener(registrationID)
Output:
2018/10/26 16:16:51 New State : STARTING
2018/10/26 16:16:51
Lifecycle Event >>> CONNECTED
Members {size:1} [
Lifecycle Event >>> STARTED
Member localhost:5701 - 936e0450-fc62-4927-9751-07c145f88a6f
]
Lifecycle Event >>> SHUTTING_DOWN
Lifecycle Event >>> SHUTDOWN
2018/10/26 16:16:51 Registered membership listener with ID 3e15ce02-4b14-4e4d-afca-bd69ea174498
2018/10/26 16:16:51 New State : CONNECTED
2018/10/26 16:16:51 New State : STARTED
2018/10/26 16:16:51 New State : SHUTTING_DOWN
2018/10/26 16:16:51 New State : SHUTDOWN
7.5.2. Distributed Data Structure Events
You can add event listeners to the distributed data structures.
7.5.2.1. Map Listener
The Map Listener is used by the Hazelcast Map.
You can listen to map-wide or entry-based events. To listen to these events, you need to implement the relevant interfaces.
An entry-based event is fired after the operations that affect a specific entry. For example, Map.Put(), Map.Remove() or Map.Evict(). An EntryEvent object is passed to the listener function. You can use the following listeners to listen to entry-based events.
• EntryExpiredListener
• EntryMergedListener
• EntryEvictedListener
• EntryUpdatedListener
• EntryRemovedListener
• EntryAddedListener
See the following example.
type entryListener struct {
}
func (l *entryListener) EntryAdded(event core.EntryEvent) {
fmt.Println("Entry Added: ", event.Key(), " ", event.Value()) // Entry Added: 1 Furkan
}
To add listener and fire an event:
m, _ := client.GetMap("m")
m.AddEntryListener(&entryListener{}, true)
m.Put("1", "Furkan")
A map-wide event is fired as a result of a map-wide operation. For example, Map.Clear() or Map.EvictAll(). A MapEvent object is passed to the listener function. You can use the following listeners to listen to map-wide events.
• MapEvictedListener
• MapClearedListener
See the following example.
type mapListener struct {
}
func (l *mapListener) MapCleared(event core.MapEvent) {
fmt.Println("Map Cleared:", event.NumberOfAffectedEntries()) // Map Cleared: 3
}
To add listener and fire a related event:
m, _ := client.GetMap("m")
m.AddEntryListener(&mapListener{}, true)
m.Put("1", "Mali")
m.Put("2", "Ahmet")
m.Put("3", "Furkan")
m.Clear()
As you see, there is a parameter in the AddEntryListener function: includeValue. It is a boolean parameter, and if it is true, the map event contains the entry value.
7.5.2.2. Entry Listener
The Entry Listener is used by the Hazelcast MultiMap and Replicated Map.
You can listen to map-wide or entry-based events by implementing the corresponding interface such as EntryAddedListener.
An entry-based event is fired after the operations that affect a specific entry. For example, MultiMap.Put(), MultiMap.Remove(). You should implement the corresponding type to listen to these events such as EntryAddedListener. An EntryEvent object is passed to the listener function.
type EntryListener struct {
}
func (l *EntryListener) EntryAdded(event core.EntryEvent) {
log.Println("Entry Added:", event.Key(), event.Value()) // Entry Added: 1 Furkan
}
multiMap.AddEntryListener(&EntryListener{}, true)
multiMap.Put("1", "Furkan")
A map-wide event is fired as a result of a map-wide operation. For example, MultiMap.Clear(). You should implement the MapClearedListener interface to listen to these events. A MapEvent object is passed to the listener function.
See the following example.
type EntryListener struct {
}
func (l *EntryListener) MapCleared(event core.MapEvent) {
log.Println("Map Cleared:", event.NumberOfAffectedEntries()) // Map Cleared: 1
}
multiMap.AddEntryListener(&EntryListener{}, true)
multiMap.Put("1", "Muhammet Ali")
multiMap.Put("1", "Ahmet")
multiMap.Put("1", "Furkan")
multiMap.Clear()
See the following headings to see supported listener functions for each data structure.
Entry Listener Functions Supported by MultiMap
• EntryAdded
• EntryRemoved
• EntryEvicted
• MapCleared
Entry Listener Functions Supported by Replicated Map
• EntryAdded
• EntryUpdated
• EntryRemoved
• EntryEvicted
• MapCleared
As you see, there is a parameter in the AddEntryListener function: includeValue. It is a boolean parameter, and if it is true, the entry event contains the entry value.
7.5.2.3. Item Listener
The Item Listener is used by the Hazelcast Queue, Set and List.
You can listen to item events by implementing the ItemAddedListener or ItemRemovedListener interface. Their functions are invoked when an item is added or removed.
The following is an example of item listener object and its registration to the Set. It also applies to Queue and List.
type itemListener struct {
}
func (l *itemListener) ItemAdded(event core.ItemEvent) {
log.Println("Item added:", event.Item()) // Item added: Furkan
}
func (l *itemListener) ItemRemoved(event core.ItemEvent) {
log.Println("Item removed:", event.Item()) // Item removed: Furkan
}
set.AddItemListener(&itemListener{}, true)
set.Add("Furkan")
set.Remove("Furkan")
As you see, there is a parameter in the AddItemListener function: includeValue. It is a boolean parameter, and if it is true, the item event contains the item value.
7.5.2.4. Message Listener
The Message Listener is used by the Hazelcast Reliable Topic and Topic.
You can listen to message events. To listen to these events, you need to implement the MessageListener interface.
See the following example.
type topicMessageListener struct {
}
func (l *topicMessageListener) OnMessage(message core.Message) error {
log.Println(message.MessageObject()) // furkan
return nil
}
topic.AddMessageListener(&topicMessageListener{})
topic.Publish("furkan")
7.6. Distributed Computing
This chapter explains how you can use Hazelcast IMDG's entry processor implementation in the Go client.
7.6.1. Using EntryProcessor
Hazelcast supports entry processing. An entry processor is a function that executes your code on a map entry in an atomic way.
An entry processor is a good option if you perform bulk processing on an Map. Usually you perform a loop of keys -- executing Map.get(key), mutating the value, and finally putting the entry back in the map using Map.put(key,value). If you perform this process from a client or from a member where the keys do not exist, you effectively perform two network hops for each update: the first to retrieve the data and the second to update the mutated value.
If you are doing the process described above, you should consider using entry processors. An entry processor executes a read and updates upon the member where the data resides. This eliminates the costly network hops described above.
NOTE: Entry processor is meant to process a single entry per call. Processing multiple entries and data structures in an entry processor is not supported as it may result in deadlocks on the server side.
Hazelcast sends the entry processor to each cluster member and these members apply it to the map entries. Therefore, if you add more members, your processing completes faster.
Processing Entries
The Map interface provides the following functions for entry processing:
• executeOnKey processes an entry mapped by a key.
• executeOnKeys processes entries mapped by a list of keys.
• executeOnEntries can process all entries in a map.
• executeOnEntriesWithPredicate can process all entries in a map with a defined predicate.
In the Go client, an EntryProcessor should be IdentifiedDataSerializable , Portable or Custom Serializable because the server should be able to deserialize it to process.
The following is an example for EntryProcessor which is IdentifiedDataSerializable.
type identifiedEntryProcessor struct {
value string
}
func (p *identifiedEntryProcessor) ReadData(input serialization.DataInput) error {
p.value = input.ReadUTF()
return input.Error()
}
func (p *identifiedEntryProcessor) WriteData(output serialization.DataOutput) error {
output.WriteUTF(p.value)
return nil
}
func (p *identifiedEntryProcessor) FactoryID() int32 {
return 5
}
func (p *identifiedEntryProcessor) ClassID() int32 {
return 1
}
Now, you need to make sure that the Hazelcast member recognizes the entry processor. For this, you need to implement the Java equivalent of your entry processor and its factory and create your own compiled class or JAR files. For adding your own compiled class or JAR files to the server's CLASSPATH, see the Adding User Library to CLASSPATH section.
The following is the Java equivalent of the entry processor in Go client given above:
import com.hazelcast.map.AbstractEntryProcessor;
import com.hazelcast.nio.ObjectDataInput;
import com.hazelcast.nio.ObjectDataOutput;
import com.hazelcast.nio.serialization.IdentifiedDataSerializable;
import java.io.IOException;
import java.util.Map;
public class IdentifiedEntryProcessor extends AbstractEntryProcessor<String, String> implements IdentifiedDataSerializable {
static final int CLASS_ID = 1;
private String value;
public IdentifiedEntryProcessor() {
}
@Override
public int getFactoryId() {
return IdentifiedFactory.FACTORY_ID;
}
@Override
public int getId() {
return CLASS_ID;
}
@Override
public void writeData(ObjectDataOutput out) throws IOException {
out.writeUTF(value);
}
@Override
public void readData(ObjectDataInput in) throws IOException {
value = in.readUTF();
}
@Override
public Object process(Map.Entry<String, String> entry) {
entry.setValue(value);
return value;
}
}
You can implement the above processor’s factory as follows:
import com.hazelcast.nio.serialization.DataSerializableFactory;
import com.hazelcast.nio.serialization.IdentifiedDataSerializable;
public class IdentifiedFactory implements DataSerializableFactory {
public static final int FACTORY_ID = 5;
@Override
public IdentifiedDataSerializable create(int typeId) {
if (typeId == IdentifiedEntryProcessor.CLASS_ID) {
return new IdentifiedEntryProcessor();
}
return null;
}
}
Now you need to configure the hazelcast.xml to add your factory as shown below.
<hazelcast>
<serialization>
<data-serializable-factories>
<data-serializable-factory factory-id="5">
IdentifiedFactory
</data-serializable-factory>
</data-serializable-factories>
</serialization>
</hazelcast>
The code that runs on the entries is implemented in Java on the server side. The client side entry processor is used to specify which entry processor should be called. For more details about the Java implementation of the entry processor, see the Entry Processor section in the Hazelcast IMDG Reference Manual.
After the above implementations and configuration are done and you start the server where your library is added to its CLASSPATH, you can use the entry processor in the Map functions. Let's take a look at the following example.
config := hazelcast.NewConfig()
identifiedFactory := &identifiedFactory{}
config.SerializationConfig().AddDataSerializableFactory(5, identifiedFactory)
client, _ := hazelcast.NewClientWithConfig(config)
mp, _ := client.GetMap("my-distributed-map")
mp.Put("key", "not-processed")
processor := &identifiedEntryProcessor{ value: value}
value, _ := mp.ExecuteOnKey("key", processor)
fmt.Println("after processing the new value is ", value)
newValue, _ := mp.Get("key")
fmt.Println("after processing the new value is ", newValue)
7.7. Distributed Query
Hazelcast partitions your data and spreads it across cluster of members. You can iterate over the map entries and look for certain entries (specified by predicates) you are interested in. However, this is not very efficient because you will have to bring the entire entry set and iterate locally. Instead, Hazelcast allows you to run distributed queries on your distributed map.
7.7.1. How Distributed Query Works
1. The requested predicate is sent to each member in the cluster.
2. Each member looks at its own local entries and filters them according to the predicate. At this stage, key-value pairs of the entries are deserialized and then passed to the predicate.
3. The predicate requester merges all the results coming from each member into a single set.
Distributed query is highly scalable. If you add new members to the cluster, the partition count for each member is reduced and thus the time spent by each member on iterating its entries is reduced. In addition, the pool of partition threads evaluates the entries concurrently in each member, and the network traffic is also reduced since only filtered data is sent to the requester.
If queried item is Portable, it can be queried for the fields without deserializing the data at the server side and hence no server side implementation of the queried object class will be needed.
Predicates Object Operators
The predicate package offered by the client includes many operators for your query requirements. Some of them are described below.
• equal: Checks if the result of an expression is equal to a given value.
• notEqual: Checks if the result of an expression is not equal to a given value.
• instanceOf: Checks if the result of an expression has a certain type.
• like: Checks if the result of an expression matches some string pattern. % (percentage sign) is the placeholder for many characters, _ (underscore) is placeholder for only one character.
• greaterThan: Checks if the result of an expression is greater than a certain value.
• greaterEqual: Checks if the result of an expression is greater than or equal to a certain value.
• lessThan: Checks if the result of an expression is less than a certain value.
• lessEqual: Checks if the result of an expression is less than or equal to a certain value.
• between: Checks if the result of an expression is between two values, inclusively.
• in: Checks if the result of an expression is an element of a certain list.
• not: Checks if the result of an expression is false.
• regex: Checks if the result of an expression matches some regular expression.
Hazelcast offers the following ways for distributed query purposes:
• Combining Predicates with AND, OR, NOT
• Distributed SQL Query
7.7.1.1. Employee Map Query Example
Assume that you have an employee map containing the values of Employee objects, as coded below.
type Employee struct {
name string
age int32
active bool
salary int64
}
func (e *Employee) ReadPortable(reader serialization.PortableReader) error {
e.name = reader.ReadUTF("name")
e.age = reader.ReadInt32("age")
e.active = reader.ReadBool("active")
e.salary = reader.ReadInt64("salary")
return reader.Error()
}
func (e *Employee) WritePortable(writer serialization.PortableWriter) error {
writer.WriteUTF("name", e.name)
writer.WriteInt32("age", e.age)
writer.WriteBool("active", e.active)
writer.WriteInt64("salary", e.salary)
return nil
}
func (e *Employee) FactoryID() int32 {
return 1
}
func (e *Employee) ClassID() int32 {
return 1
}
Note that Employee is implementing Portable. As portable types are not deserialized on the server side for querying, you don't need to implement its Java equivalent on the server side.
For the non-portable types, you need to implement its Java equivalent and its serializable factory on the server side for server to reconstitute the objects from binary formats. In this case before starting the server, you need to compile the Employee and related factory classes with server's CLASSPATH and add them to the user-lib directory in the extracted hazelcast-<version>.zip (or tar). See the Adding User Library to CLASSPATH section.
NOTE: Querying with Portable object is faster as compared to IdentifiedDataSerializable.
7.7.1.2. Querying by Combining Predicates with AND, OR, NOT
You can combine predicates by using the and, or and not operators, as shown in the below example.
mp, _ := client.GetMap("emloyees")
prdct := predicate.And(predicate.Equal("active", true), predicate.LessThan("age", 30))
value, _ := mp.ValuesWithPredicate(prdct)
In the above example code, predicate verifies whether the entry is active and its age value is less than 30. This predicate is applied to the employee map using the map.ValuesWithPredicate(predicate) method. This method sends the predicate to all cluster members and merges the results coming from them.
NOTE: Predicates can also be applied to keySet and entrySet of the Hazelcast IMDG's distributed map.
7.7.1.3. Querying with SQL
predicate.SQL takes the regular SQL where clause. Here is an example:
mp, _ := client.GetMap("employees")
prdct := predicate.And(predicate.SQL("active AND age < 30"))
value, _ := mp.ValuesWithPredicate(prdct)
Supported SQL Syntax
AND/OR: <expression> AND <expression> AND <expression>…
• active AND age > 30
• active = false OR age = 45 OR name = 'Joe'
• active AND ( age > 20 OR salary < 60000 )
Equality: =, !=, <, ⇐, >, >=
• <expression> = value
• age <= 30
• name = 'Joe'
• salary != 50000
BETWEEN: <attribute> [NOT] BETWEEN <value1> AND <value2>
• age BETWEEN 20 AND 33 ( same as age >= 20 AND age ⇐ 33 )
• age NOT BETWEEN 30 AND 40 ( same as age < 30 OR age > 40 )
IN: <attribute> [NOT] IN (val1, val2,…)
• age IN ( 20, 30, 40 )
• age NOT IN ( 60, 70 )
• active AND ( salary >= 50000 OR ( age NOT BETWEEN 20 AND 30 ) )
• age IN ( 20, 30, 40 ) AND salary BETWEEN ( 50000, 80000 )
LIKE: <attribute> [NOT] LIKE 'expression'
The % (percentage sign) is the placeholder for multiple characters, an _ (underscore) is the placeholder for only one character.
• name LIKE 'Jo%' (true for 'Joe', 'Josh', 'Joseph' etc.)
• name LIKE 'Jo_' (true for 'Joe'; false for 'Josh')
• name NOT LIKE 'Jo_' (true for 'Josh'; false for 'Joe')
• name LIKE 'J_s%' (true for 'Josh', 'Joseph'; false 'John', 'Joe')
ILIKE: <attribute> [NOT] ILIKE 'expression'
ILIKE is similar to the LIKE predicate but in a case-insensitive manner.
• name ILIKE 'Jo%' (true for 'Joe', 'joe', 'jOe','Josh','joSH', etc.)
• name ILIKE 'Jo_' (true for 'Joe' or 'jOE'; false for 'Josh')
REGEX: <attribute> [NOT] REGEX 'expression'
• name REGEX 'abc-.*' (true for 'abc-123'; false for 'abx-123')
Querying Examples with Predicates
You can use the __key attribute to perform a predicated search for entry keys. Please see the following example:
personMap, _ := client.GetMap("persons")
personMap.Put("Ahmet", 28)
personMap.Put("Ali", 30)
personMap.Put("Furkan", 23)
value , _ := personMap.ValuesWithPredicate(predicate.SQL("__key like F%"))
fmt.Println(value) //[23]
In this example, the code creates a slice with the values whose keys start with the letter "F”.
You can use the this attribute to perform a predicated search for entry values. See the following example:
personMap, _ := client.GetMap("persons")
personMap.Put("Ahmet", 28)
personMap.Put("Ali", 30)
personMap.Put("Furkan", 23)
value , _ := personMap.ValuesWithPredicate(predicate.GreaterEqual("this", 27))
fmt.Println(value) //[28 30]
In this example, the code creates a slice with the values greater than or equal to "27".
7.7.1.4. Querying with JSON Strings
You can query JSON strings stored inside your Hazelcast clusters. To query the JSON string, you first need to create a HazelcastJSONValue from the JSON string. You can use HazelcastJSONValues both as keys and values in the distributed data structures. Then, it is possible to query these objects using the Hazelcast query methods explained in this section.
person1 , _ := core.CreateHazelcastJSONValueFromString{"{ \"name\": \"John\", \"age\": 35 }"}
person2 , _ := core.CreateHazelcastJSONValueFromString{"{ \"name\": \"Jane\", \"age\": 24 }"}
person3 , _ := core.CreateHazelcastJSONValueFromString{"{ \"name\": \"Trey\", \"age\": 17 }"}
mp.Put(1, person1)
mp.Put(2, person2)
mp.Put(3, person3)
peopleUnder21, _ := mp.ValuesWithPredicate(predicate.LessThan("age", 21))
When running the queries, Hazelcast treats values extracted from the JSON documents as Java types so they can be compared with the query attribute. JSON specification defines five primitive types to be used in the JSON documents: number,string, true, false and nil. The string, true/false and nil types are treated as String, boolean and null, respectively. We treat the extracted number values as longs if they can be represented by a long. Otherwise, numbers are treated as doubles.
It is possible to query nested attributes and arrays in the JSON documents. The query syntax is the same as querying other Hazelcast objects using the Predicates.
/**
* Sample JSON object
*
* {
* "departmentId": 1,
* "room": "alpha",
* "people": [
* {
* "name": "Peter",
* "age": 26,
* "salary": 50000
* },
* {
* "name": "Jonah",
* "age": 50,
* "salary": 140000
* }
* ]
* }
*
*
* The following query finds all the departments that have a person named "Peter" working in them.
*/
departmentWithPeter, _ := departments.values(predicate.Equal("people[any].name", "Peter"))
HazelcastJSONValue is a lightweight wrapper around your JSON strings. It is used merely as a way to indicate that the contained string should be treated as a valid JSON value. Hazelcast does not check the validity of JSON strings put into to the maps. Putting an invalid JSON string into a map is permissible. However, in that case whether such an entry is going to be returned or not from a query is not defined.
7.7.2. Fast-Aggregations
Fast-Aggregations feature provides some aggregate functions, such as sum, average, max, and min, on top of Hazelcast Map entries. Their performance is perfect since they run in parallel for each partition and are highly optimized for speed and low memory consumption.
The aggregator package provides a wide variety of built-in aggregators. The full list is presented below:
• Count
• Float64Average
• Float64Sum
• FixedPointSum
• FloatingPointSum
• Max
• Min
• Int32Average
• Int32Sum
• Int64Average
• Int64Sum
You can use these aggregators with the Map.Aggregate() and Map.AggregateWithPredicate() functions.
See the following example.
mp, _ := client.GetMap("brothersMap")
mp.Put("Muhammet Ali", 30)
mp.Put("Ahmet", 27)
mp.Put("Furkan", 23)
agg, _ := aggregator.Count("this")
count, _ := mp.Aggregate(agg)
fmt.Println("There are", count, "brothers.") // There are 3 brothers.
count, _ = mp.AggregateWithPredicate(agg, predicate.GreaterThan("this", 25))
fmt.Println("There are", count, "brothers older than 25.") // There are 2 brothers older than 25.
avg, _ := aggregation.NewInt64Average("this")
avgAge, _ := mp.Aggregate(avg)
fmt.Println("Average age is", avgAge) // Average age is 26.666666666666668
7.8. Monitoring
7.8.1. Enabling Client Statistics
You can monitor your clients using Hazelcast Management Center.
As a prerequisite, you need to enable the client statistics before starting your clients. This can be done by setting the hazelcast.client.statistics.enabled system property to true on the member as the following:
<hazelcast>
...
<properties>
<property name="hazelcast.client.statistics.enabled">true</property>
</properties>
...
</hazelcast>
Also, you need to enable the client statistics in the Go client. There are two properties related to client statistics:
• hazelcast.client.statistics.enabled: If set to true, it enables collecting the client statistics and sending them to the cluster. When it is true you can monitor the clients that are connected to your Hazelcast cluster, using Hazelcast Management Center. Its default value is false.
• hazelcast.client.statistics.period.seconds: Period in seconds the client statistics are collected and sent to the cluster. Its default value is 3.
You can enable client statistics and set a non-default period in seconds as follows:
config := hazelcast.NewConfig()
config.SetProperty(property.StatisticsEnabled.Name(), "true")
config.SetProperty(property.StatisticsPeriodSeconds.Name(), "4")
After enabling the client statistics, you can monitor your clients using Hazelcast Management Center. See the Monitoring Clients section in the Hazelcast Management Center Reference Manual for more information on the client statistics.
7.8.2. Logging Configuration
By default Hazelcast Go client uses DefaultLogger for logging. The default logging level is info. If you want to change the logging level for the client, you should use LoggingLevel property:
config := hazelcast.NewConfig()
config.SetProperty(property.LoggingLevel.Name(), logger.ErrorLevel)
As described in Client System Properties Section you can also set the log level via an environment variable with this property:
os.Setenv(property.LoggingLevel.Name(), logger.ErrorLevel)
If you are using a custom logger, LoggingLevel property will not be used.
Possible log levels are as follows:
// OffLevel disables logging.
OffLevel = "off"
// ErrorLevel level. Logs. Used for errors that should definitely be noted.
// Commonly used for hooks to send errors to an error tracking service.
ErrorLevel = "error"
// WarnLevel level. Non-critical entries that deserve eyes.
WarnLevel = "warn"
// InfoLevel level. General operational entries about what's going on inside the
// application.
InfoLevel = "info"
// DebugLevel level. Usually only enabled when debugging. Very verbose logging.
DebugLevel = "debug"
// TraceLevel level. Designates finer-grained informational events than the Debug.
TraceLevel = "trace"
The Default Logger's format is as follows:
[Time] [caller method name]
[Log level] [Client Name] [Group Name] [Client Version] [Log Message]
An example default log message is as follows:
2018/11/30 17:48:52 github.com/hazelcast/hazelcast-go-client/internal.(*lifecycleService).fireLifecycleEvent
INFO: hz.client_1 [dev] [0.4] New State : STARTED
If you want to modify the Default Logger for your convenience, you can do so by accessing the embedded built-in go logger:
l := logger.New()
l.SetPrefix("myPrefix ")
config := hazelcast.NewConfig()
config.LoggerConfig().SetLogger(l)
The same log message will now be as follows:
myPrefix 2018/11/30 17:55:40 github.com/hazelcast/hazelcast-go-client/internal.(*lifecycleService).fireLifecycleEvent
INFO: hz.client_1 [dev] [0.4] New State : CONNECTED
If you want to set a custom logger, you can do so by implementing Logger interface:
type customLogger struct {
}
func (c *customLogger) Debug(args ...interface{}) {
}
func (c *customLogger) Trace(args ...interface{}) {
}
func (c *customLogger) Info(args ...interface{}) {
log.Println(args)
}
func (c *customLogger) Warn(args ...interface{}) {
}
func (c *customLogger) Error(args ...interface{}) {
}
Note that the customLogger only logs Info level to console. This way users can implement only the levels they need in the format they want to.
After implementing the Logger interface, you need to set it as the client's logger:
customLogger := &customLogger{}
config := hazelcast.NewConfig()
config.LoggerConfig().SetLogger(customLogger)
Note that when you call SetLogger method, the hazelcast property LoggingLevel will not be used.
You can also integrate any third party logger with Logger interface:
Logrus
logger := logrus.New()
logger.SetLevel(logrus.DebugLevel)
config := hazelcast.NewConfig()
config.LoggerConfig().SetLogger(logger)
The same log message will now be:
time="2018-11-30T18:09:52+03:00" level=info msg="New State : CONNECTED"
Note that Logrus already implements the Logger interface, therefore we did not need to do any extra work.
Zap
type zapLogger struct {
*zap.Logger
}
func (z *zapLogger) Debug(args ...interface{}) {
message := fmt.Sprintln(args)
z.Logger.Debug(message)
}
func (z *zapLogger) Trace(args ...interface{}) {
message := fmt.Sprintln(args)
z.Logger.Debug(message)
}
func (z *zapLogger) Info(args ...interface{}) {
message := fmt.Sprintln(args)
z.Logger.Info(message)
}
func (z *zapLogger) Warn(args ...interface{}) {
message := fmt.Sprintln(args)
z.Logger.Warn(message)
}
func (z *zapLogger) Error(args ...interface{}) {
message := fmt.Sprintln(args)
z.Logger.Error(message)
}
Then, you need to set it as the client's logger:
opt := zap.AddCallerSkip(1)
logger, _ := zap.NewProduction(opt)
zapLogger := &zapLogger{logger}
config := hazelcast.NewConfig()
config.LoggerConfig().SetLogger(zapLogger)
Note that we call zap.AddCallerSkip(1) to skip our wrapper method.
The same log message will now be:
{"level":"info","ts":1543594846.9142249,"caller":"internal/lifecycle.go:89","msg":"[New State : CONNECTED]\n"}
Glog
type gLogger struct {
}
func (*gLogger) Debug(args ...interface{}) {
// NO OP
}
func (*gLogger) Trace(args ...interface{}) {
// NO OP
}
func (*gLogger) Info(args ...interface{}) {
glog.Info(args)
}
func (*gLogger) Warn(args ...interface{}) {
glog.Warning(args)
}
func (*gLogger) Error(args ...interface{}) {
glog.Error(args)
}
Then, you need to set it as the client's logger:
config := hazelcast.NewConfig()
config.LoggerConfig().SetLogger(&gLogger{})

Client is a Hazelcast client. Multiple Hazelcast clients can be created. Each Hazelcast client has its own socket, goroutines. Hazelcast client enables you to do all Hazelcast operations without being a member of the cluster. It connects to one of the cluster members and delegates all cluster wide operations to it. When the connected cluster member dies, client will automatically switch to another live member.
func NewClient
func NewClient() (Client, error)
NewClient creates and returns a new Client. Hazelcast client enables you to do all Hazelcast operations without being a member of the cluster. It connects to one of the cluster members and delegates all cluster wide operations to it. When the connected cluster member dies, client will automatically switch to another live member.
func NewClientWithConfig
func NewClientWithConfig(config *config.Config) (Client, error)
NewClientWithConfig creates and returns a new Client with the given config. Hazelcast client enables you to do all Hazelcast operations without being a member of the cluster. It connects to one of the cluster members and delegates all cluster wide operations to it. When the connected cluster member dies, client will automatically switch to another live member.

How can we prove that the limit of sequence $\lim_{n\rightarrow\infty}a_{n}=0$ if $a_{n}>0$ and $\lim_{n\to\infty}\frac{a_{n}}{a_{n+1}}=l>1$

There is some $N$ sufficiently large so that, for all $n > N$, we have $a_{n+1}/a_n \leq c < 1$.
For for $n > 0$ we have $0 < a_{n+N} \leq a_N c^n$. By the squeeze theorem, $a_{n+N} \rightarrow 0$.
share|improve this answer
The key observation in applying the squeeze theorem is $a_{N}$ is fixed. – toypajme May 24 '12 at 14:18
I don't certainly get the point that how we reach the inequality $a_{n+N}<a_{N}c^n$ thanks – Francis King May 24 '12 at 15:09
I have get the point.thanks – Francis King May 24 '12 at 15:19
Hint:
If $\lim\limits_{n\rightarrow\infty}{a_n\over a_{n+1}}=l>1$, then $\lim\limits_{n\rightarrow\infty}{a_{n+1}\over a_n }={1\over l}<1$. Choose $0<c<1$, and choose $N$ so that if $n\ge N$, then ${a_{n+1}\over a_n}<c$.
Then note:
$\ \ \ \ a_{N+1}<{c}\, a_N$,
$\ \ \ \ a_{N+2}<{c}\,a_{N+1}<{c^2}a_N$,
$\ \ \ \ a_{N+3}<{c}\,a_{N+2}<{c^3}a_N$,
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \vdots$
share|improve this answer
thanks. your step-by-step induction helps me a lot. – Francis King May 24 '12 at 15:20
Another proof not-by-the-definition: the series $\,\displaystyle{\sum_{n=1}^\infty a_n\,}$ is a positive one and it converges by D'Alembert's test (or the quotient test), since $\,\displaystyle{\frac{a_{n+1}}{a_n}\to \frac{1}{l}<1}\,$ , thus it must be $\,a_n\to 0$
share|improve this answer
Right. But I guess that D'Alembert's test is proved the same way as the fact asked here. Your suggestion might be a circular reasoning. – Siminore May 24 '12 at 16:27
No, or at least not the proof I know, which proves the sequence of partial sums of the series is bounded (using a geometric convergente series) and thus the series converges. – DonAntonio May 24 '12 at 18:01

RTTI简介
代码编译运行平台：VS2017+Debug+Win32
RTTI（Runtime Type Identification）是“运行时类型识别”的意思。面向对象的编程语言，像C++，Java，Delphi都提供了对RTTI的支持。 本文将简略介绍 RTTI 的一些背景知识、描述 RTTI 的概念，并通过具体例子和代码介绍什么时候使用以及如何使用 RTTI。本文还将详细描述两个重要的RTTI运算符的使用方法，它们是typeid和dynamic_cast。
1.typeid的用法
1.1type_info类
typeid的结果是const type_info&。所以下面先对type_info类做下介绍：
class type_info
{
public:
virtual ~type_info();
size_t hash_code() const
_CRTIMP_PURE bool operator==(const type_info& rhs) const;
_CRTIMP_PURE bool operator!=(const type_info& rhs) const;
_CRTIMP_PURE int before(const type_info& rhs) const;
_CRTIMP_PURE const char* name() const;
_CRTIMP_PURE const char* raw_name() const;
};
我们不能直接实例化 type_info 类的对象，因为该类只有一个私有复制构造函数。 构造（临时）type_info 对象的唯一方式是使用 typeid 运算符。 由于赋值运算符也是私有的，因此不能复制或分配类 type_info 的对象。
1.2typeid应用实例
1.2.1typeid静态的类型判断
typeid可以静态地确定操作数的类型，也可以动态地确定操作数的类型，这取决于操作数本身是否拥有虚函数。当typeid的操作数是一个基本类型的变量，或者是一个不带虚函数的对象时，typeid的运行结果是在编译阶段决定的。所以是一种静态的类型判断。见下面的例子。
#include <iostream>
using namespace std;
class A
{
int i;
public:
void show()
{
cout<<"In class A"<<endl;
}
};
class B
{
int i;
public:
void show()
{
cout<<"In class B"<<endl;
}
};
template <typename T>void func(T& a)
{
if(typeid(A)==typeid(T))
cout<<"is A"<<endl;
if(typeid(B)==typeid(T))
cout<<"is B"<<endl;
}
int main()
{
if(typeid(B)==typeid(A))
cout<<"A equal to B"<<endl;
else
cout<<"A not equal to B"<<endl;
A a;
B b;
func<A>(a);
func<B>(b);
cout<<typeid(B).name()<<endl;
}
程序输出结果：
A not equal to B
is A
is B
class B
在上面的程序中，函数模板func()被实例化为class A和class B时，typeid(T)是在编译阶段静态确定的。在函数模板内部，可以通过typeid操作决定在模板参数被实例化为不同数据类型的时要采取不同的行动。
1.2.2typeid动态类型判断
typeid更多的时候是在运行时用来动态地确定指针或引用所指向对象的类型，这时要求typeid所操作的对象一定要拥有虚函数。见下面的程序。
#include <iostream>
using namespace std;
class A
{
virtual void func(){}
};
class B:public A{};
void reportA(A* pa)
{
if(typeid(*pa)==typeid(A))
cout<<"Type of *pb is A"<<endl;
else if(typeid(*pa)==typeid(B))
cout<<"Type of *pb is B"<<endl;
}
void reportB(B* pb)
{
if(typeid(*pb)==typeid(A))
cout<<"Type of *pb is A"<<endl;
else if(typeid(*pb)==typeid(B))
cout<<"Type of *pb is B"<<endl;
}
int main()
{
A a,*pa;
B b,*pb;
pa=&a;
reportA(pa);
pa=&b;
reportA(pa);
pb=static_cast<B*>(&a);
reportB(pb);
pb=&b;
reportB(pb);
}
程序输出结果：
Type of *pb is A
Type of *pb is B
Type of *pb is A
Type of *pb is B
从上面的运行结果可以看出，使用typeid确实能够在程序运行期间动态地判断指针所指对象的实际类型。使用引用可以到达同样的效果，因为引用的底层实现就是指针。
要注意的是： （1）如果在Class A的定义中，将函数func()定义为普通函数（即将前面的virtual关键字去掉），那么typeid(*pa)的结果永远是typeid(A)，而typeid(*pb)的结果永远是typeid(B)。也就是说，由于pa和pb所指向的对象中没有虚函数，该对象就没有虚函数表存放运行时信息，typeid实际就变成了一种静态运算符。
（2）C++中的一切“动态”机制，包括虚函数、RTTI等，都必须通过指针或引用来实现。换句话说，指针所指的对象或引用所绑定的对象，在运行阶段可能与声明指针或引用时的类型不一致。如果不使用指针或引用，而是直接通过对象名访问对象，那么即使对象拥有动态信息（虚函数表），对象的动态信息与静态申明对象时的信息必然一致，就没有必要访问虚函数表；而如果对象不拥有虚函数，就没有虚函数表存放动态信息，也就无法在运行时动态判断指针所指向对象（或引用所绑定对象）的实际类型。
2.dynamic_cast的用法

Create an executable FatJar in Gradle
Fat Jar is also know as uber jar which consists of all the classes along with the dependencies required to the run the application.
Setup build.gradle
plugins {
id 'java'
}
repositories {
mavenCentral()
}
dependencies {
compile jackson_libraries.core
compile jackson_libraries.databind
compile jackson_libraries.annotations
}
Override the default JAR task
By default jar task build jar without any dependencies, we will override the behavior of the jar task by adding a few lines of code in the build.gradle which will include all the dependencies to the jar.
jar {
manifest {
attributes "Main-Class": "in.asvignesh.MainClass"
}
from {
configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
}
}
The final gradle file will look like
plugins {
id 'java'
}
repositories {
mavenCentral()
}
dependencies {
compile jackson_libraries.core
compile jackson_libraries.databind
compile jackson_libraries.annotations
}
jar {
manifest {
attributes "Main-Class": "in.asvignesh.MainClass"
}
from {
configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
}
}
Now running the jar will generate the executable jar with the dependencies.

Import Attributes
Champions: Sven Sauleau (@xtuc), Daniel Ehrenberg (@littledan), Myles Borins (@MylesBorins), Dan Clark (@dandclark), and Nicolò Ribaudo (@nicolo-ribaudo).
Status: Stage 3
⚠️ The specification in this proposal might be out of date. tc39/ecma262#3057 is the latest version.
Some of the changes present in the current specification have not been presented to committee yet: #142
Please leave any feedback you have in the issues!
Synopsis
The Import Attributes proposal, formerly known as Import Assertions, adds an inline syntax for module import statements to pass on more information alongside the module specifier. The initial application for such attributes will be to support additional types of modules in a common way across JavaScript environments, starting with JSON modules.
The syntax will be as follows (shown here is the proposed method for importing a JSON module):
import json from "./foo.json" with { type: "json" };
import("foo.json", { with: { type: "json" } });
The specification of JSON modules was originally part of this proposal, but it was resolved during the July 2020 meeting to split JSON modules out into a separate Stage 3 proposal.
Motivation
Standards-track JSON ES modules were proposed to allow JavaScript modules to easily import JSON data files, similarly to how they are supported in many nonstandard JavaScript module systems. This idea quickly got broad support from web developers and browsers, and was merged into HTML, with an implementation for V8/Chromium created by Microsoft.
However, in an issue, Ryosuke Niwa (Apple) and Anne van Kesteren (Mozilla) proposed that security would be improved if some syntactic marker were required when importing JSON modules and similar module types which cannot execute code, to prevent a scenario where the responding server unexpectedly provides a different MIME type, causing code to be unexpectedly executed. The solution was to somehow indicate that a module was JSON, or in general, not to be executed, somewhere in addition to the MIME type.
Some developers have the intuition that the file extension could be used to determine the module type, as it is in many existing non-standard module systems. However, it's a deep web architectural principle that the suffix of the URL (which you might think of as the "file extension" outside of the web) does not lead to semantics of how the page is interpreted. In practice, on the web, there is a widespread mismatch between file extension and the HTTP Content Type header. All of this sums up to it being infeasible to depend on file extensions/suffixes included in the module specifier to be the basis for this checking.
There are other possible pieces of metadata which could be associated with modules, see #8 and tc39/proposal-import-reflection#18 for further discussion.
Proposed ES module types that are blocked by this security concern, in addition to JSON modules, include CSS modules and potentially HTML modules if the HTML module proposal is restricted to not allow script.
Rationale
There are three places where this data could be provided:
• As part of the module specifier (e.g., as a pseudo-scheme)
• Challenges: Adds complexity to URLs or other module specifier syntaxes, and risks being confusing to developers (further discussion: #11)
• webpack supports this sort of construct (docs).
• Demand from users for similar behavior in Parcel, with pushback from some maintainers (#3477)
• Separately, out of band (e.g., a separate resource file)
• Challenges: How to load that resource file; what should the format be; unergonomic to have to jump between files during development (further discussion: #13)
• In the JavaScript source text
• Challenges: Requires a change at the JavaScript language level (this proposal)
This proposal pursues the third option, as we expect it to lead to the best developer experience, and are hopeful that language design/standardization issues can be resolved.
Proposed syntax
Import attributes have to be made available in several different contexts. They use a key-value syntax is used preceded by the with keyword, with the key type used as an example indicating the module type. Such key-value syntax can be used in various different contexts.
import statements
The ImportDeclaration would allow any arbitrary attributes after the with keyword.
For example, the type attribute could be used to indicate a module type, for example importing a JSON module with the following syntax.
import json from "./foo.json" with { type: "json" };
The with syntax in the ImportDeclaration statement uses curly braces, for the following reasons (as discussed in #5):
• JavaScript developers are already used to the Object literal syntax and since it allows a trailing comma copy/pasting attributes will be easy.
• it clearly indicates the end of the attributes list when splitting them across multiple lines.
re-export statements
Similar to import statements, the ExportDeclaration, when re-exporting from another module, would allow any arbitrary attributes after the with keyword.
export { val } from './foo.js' with { type: "javascript" };
dynamic import()
The import() pseudo-function would allow import attributes to be indicated in an options bag in the second argument.
import("foo.json", { with: { type: "json" } })
The second parameter to import() is an options bag, with the only option currently defined to be with: the value here is an object containing the import attributes. There are other proposals for entries to put in the options bag: for example, the Module Source Imports proposal introduces a phase property.
Integration of modules into environments
Host environments (e.g., the Web platform, Node.js) often provide various different ways of loading modules. The analogous string could be passed through these ways of loading other kinds of modules.
Worker instantiation
new Worker("foo.wasm", { type: "module", with: { type: "webassembly" } });
Sidebar about WebAssembly module types and the web: it's still uncertain whether importing WebAssembly modules would need to be marked specially, or would be imported just like JavaScript. Further discussion in #19.
HTML
Although changes to HTML won't be specified by TC39, an idea here would be that each import attribute, preceded by with, becomes an HTML attribute which could be used in script tags.
<script src="foo.wasm" type="module" withtype="webassembly"></script>
(See the caveat about WebAssembly above.)
WebAssembly
In the context of the WebAssembly/ESM integration proposal: for imports of other module types from within a WebAssembly module, this proposal would introduce a new custom section (named importattributes) that will annotate with attributes each imported module (which is listed in the import section).
Proposed semantics and interoperability
This proposal does not specify behavior for any particular attribute key or value. The JSON modules proposal will specify that type: "json" must be interpreted as a JSON module, and will specify common semantics for doing so. It is expected the type attribute will be leveraged to support additional module types in future TC39 proposals as well as by hosts. HTML and CSS modules are under consideration, and these may use similar explicit type syntax when imported.
Attributes in addition than type may also be introduced for purposes not yet foreseen.
JavaScript implementations are encouraged to reject attributes and type values which are not implemented in their environment (rather than ignoring them). This is to allow for maximal flexibility in the design space in the future--in particular, it enables new import attributes to be defined which change the interpretation of a module, without breaking backwards-compatibility.
FAQ
Why not out of band?
Why not both? The champions of this proposal think that exploring both an in- and out of band solutions to various kinds of metadata. While we prefer in-band metadata for module types, we are happy to see the development of various out-of-band manifests of modules being proposed and implemented in certain JS environments:
This proposal does not exclude out-of-band metadata being used for module types. And it definitely doesn't argue that all metadata should be in-band. For example, integrity hashes simply don't work in-band, both because module circularities make them impossible to calculate, and because of the need for a "cascading" update when a deep dependency changes.
Out-of-band solutions face certain downsides; these are not necessarily fatal, but are interesting to take into account when considering the solution space and making tradeoffs:
• By-hand authoring experience: While an in-band solution is somewhat verbose, it is also more straightforward for developers to adopt when writing code without much tooling. For smaller projects developers do not need to create an extra file by hand.
• Tooling complexity for large projects: For large project with many dependencies, developers will not have to worry about creating a large manifest by compiling the metadata of all of their dependencies. Module authors will also not have to worry about shipping a manifest in order for consumers to be able to run their modules.
• Performance tradeoffs: The experience in Node.js's experimental, out-of-band policy files is that they can carry significant startup cost, due to certain aspects of loading and parsing.
How is common behavior ensured across JavaScript environments?
A central goal of this proposal is to share as much syntax and behavior across JavaScript environments as possible. To the same end, we also propose a standardization of JSON modules to the extent that this is possible (omitting just the contents of the redundant type check, which necessarily differs between environments, in addition to the pre-existing host-defined parts such as interpreting the module specifier and fetching the module).
However, at the same time, behavior of modules in general, and the set of module types specifically, is expected to differ across JavaScript environments. For example, WebAssembly, HTML and CSS modules may not make sense in certain minimal embedded JavaScript environments. We hope that environments can experiment and collaborate where it makes sense for them.
We see the management of compatibility issues across environments as similar, independent of whether metadata is held in-band or out-of-band. An out of band solution would also suffer from the risk of inconsistent implementation or support across host environments if some kind of coordination does not occur.
The topic of attribute divergence is further discussed in #34.
How would this proposal work with caching?
Attributes are part of the module cache key and can affect how a module is loaded: the cache key is extended from (referrer, specifier) to (referrer, specifier, attributes).
Why not use more terse syntax to indicate module types, like import json from "./foo.json" as "json"?
Another option considered and not selected has been to use a single string as the attribute, indicating the type. This option is not selected due to its implication that any particular attribute is special; even though this proposal only specifies the type attribute, the intention is to be open to more attributes in the future. (discussion in #12).
Should more than just strings be supported as attribute values?
We could permit import attributes to have more complex values than simply strings, for example:
import value from "module" with { attr: { key1: "value1", key2: [1, 2, 3] } };
This would allow import attributes to scale to support a larger variety of metadata.
We propose to omit this generalization in the initial proposal, as a key/value list of strings already affords significant flexibility to start, but we're open to a follow-on proposal providing this kind of generalization.
What are you open to changing? When do we have to settle down on the details?
We are planning to make descisions and reach consensus during specific stages of this proposal. Here's our plan.
Original plan before Stage 2 and Stage 3
Before stage 2
We have achieved consensus on the following core decisions as part of Stage 2, including:
• The attribute form; key-value or single string (#12)
// Not selected
import value from "module" as "json";
// Not selected
import value from "module" with type: "json";
// Proposal that was approved from Stage 2 to Stage 3 the first time
import value from "module" assert { type: "json" };
Before stage 3
After Stage 2 and before Stage 3, we're open to settling on some less core details, such as:
• Considering alternatives for the with/if/assert keywords (#3)
import value from "module" when { type: 'json' };
import value from "module" given { type: 'json' };
• How dynamic import would accept import attributes:
import("foo.wasm", { with: { type: "webassembly" } });
For consistency the assert key is used for both dynamic and static imports.
An alternative would be to remove the assert nesting in the object:
import("foo.wasm", { type: "webassembly" });
However, that's not possible with the Worker API since it already uses an object with a type key as the second parameter. Which would make the APIs inconsistent.
Before Stage 4
• The integration of import attributes into various host environments.
• For example, in the Web Platform, how import attributes would be enabled when launching a worker (if that is supported in the initial version to be shipped on the Web) or included in a <script> tag.
new Worker("foo.wasm", { type: "module", with: { type: "webassembly" } });
Standardization here would consist of building consensus not just in TC39 but also in WHATWG HTML as well as the Node.js ESM effort and a general audit of semantic requirements across various host environments (#10, #24 and #25).
History
• 2019-12: The proposal, named module attributes is approved for Stage 1 (notes part 1, notes part 2, slides) to explore metadata for module imports, and to explore guarantees about modules with no code execution.
• 2020-06: Module attributes advances to Stage 2 (notes part 1, notes part 2, slides), with consensus based on the restriction that import attributes cannot be part of the cache key in the modules map. The proposed syntax is import { x } from "./mod" with type: "json", something: "else";.
• 2020-09: The proposal, renamed to import assertions, advances to Stage 3 (notes, slides). The rename better describes the agreed assert-only semantics, and the keyword changes from with to assert. However, the proposal relaxes the caching restriction so that HTML can still include the module type as part of the cache key, while still respecting the "spirit" of the proposal.
• 2021-052022-02: The proposal, with the import { x } from "./mod" assert { type: "json" }; syntax, is implemented and shipped in Chrome, Node.js and Deno. They all support the JSON modules proposal.
• 2023-01: Due to incommpatibility with the semantics needed by HTML for non-JavaScript modules, specifically regarding HTTP fetching and CSPs, the proposal is demoted back to Stage 2 (notes part 1, notes part 2, slides) to investigate a solution to the web platform's needs.
• 2023-03: The proposal is renamed to Import attributes and moves back to Stage 3 (TODO: notes, slides). The restriction on the cache key is completely removed, and the keyword changes back from assert to with: import { x } from "./mod" with { type: "json" };. For compatibility with existing implementations, the assert keyword will still be supported until it's safe to remove it, if it will ever be.

Debugging Hard Fault & Other Exceptions
on ARM Cortex-M3 and ARM Cortex-M4 microcontrollers
Introduction
The ARM Cortex-M core implements a set of fault exceptions. Each exception relates to an error condition. If the error occurs, the ARM Cortex-M core stops executing the current instruction, and branches to the exception’s handler function. This mechanism is just like that used for interrupts, where the ARM Cortex-M core branches to an interrupt handler when it accepts an interrupt.
The CMSIS names for the fault handlers are as follows:
• UsageFault_Handler()
• BusFault_Handler()
• MemMang_Handler()
• HardFault_Handler()
The exact circumstances under which the ARM Cortex-M core calls each of these handlers is out of scope of this document. See the ARM Cortex-M literature from ARM, and various other sources, if you are interested in the details. For the purpose of this document it is enough to say that, if your application ends up in one of these handlers, then something has gone wrong. Hard faults are the most common fault type, as other fault types that are not enabled individually will be escalated to become a hard fault.
Despite the numerous RTOS support requests from people explaining that, when using the RTOS kernel, their application ends up in the hard fault handler, when the issue has been worked through, it is always shown that the cause of the hardware fault is not the kernel, but one of the following:
Hard fault debugging should start by ensuring the software application follows the guidelines provided on the two pages linked to in the first two bullet points above. If, after that, hard faults still persist, then it will be necessary to determine the system state at the time the fault occurred. Debuggers do not always make that easy, so the rest of this page describes a software technique than can be used for the purpose.
Determining Which Exception Handler is Executing
It is common for interrupt vector tables to install the same handler for every interrupt/exception source. The default handlers are declared as weak symbols to allow the application writer to install their own handler simply by implementing a function with the correct name. If an interrupt occurs for which the application writer has not provided their own handler then the default handler will execute.
Default interrupt handlers are typically implemented as an infinite loop. If an application ends up in such a default handler it is first necessary to determine which interrupt is actually executing.
The code snippet below demonstrates how to add a few instructions to a default infinite loop handler to load the number of the executing interrupt into register 2 (r2) before the infinite loop is entered.
Interrupt numbers read from the NVIC in this way are relative to the start of the vector table, in which entries for system exceptions (such as the hard fault) appear before entries for peripheral interrupts. If r2 contains the value 3 then, a hard fault exception is being handled. If r2 contains a value equal to or greater than 16, then a peripheral interrupt is being handled – and the interrupting peripheral can be determined by subtracting 16 from the interrupt number.
Default_Handler:
/* Load the address of the interrupt control register into r3. */
ldr r3, NVIC_INT_CTRL_CONST
/* Load the value of the interrupt control register into r2 from the
address held in r3. */
ldr r2, [r3, #0]
/* The interrupt number is in the least significant byte - clear all
other bits. */
uxtb r2, r2
Infinite_Loop:
/* Now sit in an infinite loop - the number of the executing interrupt
is held in r2. */
b Infinite_Loop
.size Default_Handler, .-Default_Handler
.align 4
/* The address of the NVIC interrupt control register. */
NVIC_INT_CTRL_CONST: .word 0xe000ed04
Debugging a ARM Cortex-M Hard Fault
The stack frame of the fault handler contains the state of the ARM Cortex-M registers at the time that the fault occurred. The code below shows how to read the register values from the stack into C variables. Once this is done, the values of the variables can be inspected in a debugger just as an other variable.
First, a very short assembly function is defined to determine which stack was being used when the fault occurred. Once this is done, the fault handler assembly code passes a pointer to the stack into a C function called prvGetRegistersFromStack().
The fault handler is shown below using GCC syntax. Note that the function is declared as being naked, so it does not contain any compiler generated code (for example, there is no function entry prologue code).
/* The prototype shows it is a naked function - in effect this is just an
assembly function. */
static void HardFault_Handler( void ) __attribute__( ( naked ) );
/* The fault handler implementation calls a function called
prvGetRegistersFromStack(). */
static void HardFault_Handler(void)
{
__asm volatile
(
" tst lr, #4 n"
" ite eq n"
" mrseq r0, msp n"
" mrsne r0, psp n"
" ldr r1, [r0, #24] n"
" ldr r2, handler2_address_const n"
" bx r2 n"
" handler2_address_const: .word prvGetRegistersFromStack n"
);
}
The implementation of prvGetRegistersFromStack() is shown below. prvGetRegistersFromStack() copies the register values from the stack into the C variables, then sits in a loop. The variables are named to indicate the register value that they hold. Other registers will not have changed since the fault occurred, and can be viewed directly in the debugger’s CPU register window.
void prvGetRegistersFromStack( uint32_t *pulFaultStackAddress )
{
/* These are volatile to try and prevent the compiler/linker optimising them
away as the variables never actually get used. If the debugger won't show the
values of the variables, make them global my moving their declaration outside
of this function. */
volatile uint32_t r0;
volatile uint32_t r1;
volatile uint32_t r2;
volatile uint32_t r3;
volatile uint32_t r12;
volatile uint32_t lr; /* Link register. */
volatile uint32_t pc; /* Program counter. */
volatile uint32_t psr;/* Program status register. */
r0 = pulFaultStackAddress[ 0 ];
r1 = pulFaultStackAddress[ 1 ];
r2 = pulFaultStackAddress[ 2 ];
r3 = pulFaultStackAddress[ 3 ];
r12 = pulFaultStackAddress[ 4 ];
lr = pulFaultStackAddress[ 5 ];
pc = pulFaultStackAddress[ 6 ];
psr = pulFaultStackAddress[ 7 ];
/* When the following line is hit, the variables contain the register values. */
for( ;; );
}
Using the Register Values
[See also “Handling Imprecise Faults” below]
The first register of interest is the program counter. In the code above, the variable pc contains the program counter value. When the fault is a precise fault, the pc holds the address of the instruction that was executing when the hard fault (or other fault) occurred. When the fault is an imprecise fault, then additional steps are required to find the address of the instruction that caused the fault.
To find the instruction at the address held in the pc variable, either…
1. Open an assembly code window in the debugger, and manually enter the address to view the assembly instructions at that address, or
2. Open the break point window in the debugger, and manually define an execution or access break point at that address. With the break point set, restart the application to see which line of code the instruction relates to.
Knowing the instruction that was being executed when the fault occurred allows you to know which other register values are also of interest. For example, if the instruction was using the value of R7 as an address, then the value of R7 needs to be know. Further, examining the assembly code, and the C code that generated the assembly code, will show what R7 actually holds (it might be the value of a variable, for example).
Handling Imprecise Faults
ARM Cortex-M faults can be precise or imprecise. If the IMPRECISERR bit (bit 2) is set in the BusFault Status Register (or BFSR, which is byte accessible at address 0xE000ED29) is set then the fault is imprecise.
It is harder to determine the cause of an imprecise fault because the fault will not necessarily occur concurrently with the instruction that caused the fault. For example, if writes to memory are cached then there might be a delay between an assembly instruction initiating a write to memory and the write to memory actually occurring. If such a delayed write operation is invalid (for example, a write is being attempted to an invalid memory location) then an imprecise fault will occur, and the program counter value obtained using the code above will not be the address of the assembly instruction that initiated the write operation.
In the above example, turning off write buffering by setting the DISDEFWBUF bit (bit 1) in the Auxiliary Control Register (or ACTLR) will result in the imprecise fault becoming a precise fault, which makes the fault easier to debug, albeit at the cost of slower program execution.

The natural log calculator determines the logarithm to the base of a famous mathematical constant, e, an irrational number with an approximate value of e = 2.71828. But, what is the natural logarithm, ln x, of a given number x? This is the power the number e has to be raised to in order to result in a given number x.
How to use the natural logarithm calculator
Like all other logarithms, the natural logarithm of x returns the power, or exponent, to which a given base e must be raised to yield back the number x. It is easier to understand this notion when the base is an integer, for example 2 or 3:
log2 16 = 4 since 24 = 16
log3 81 = 4 since 34 = 81.
In the case of the natural logarithm, this is somewhat less intuitive, because it's base, e, is not an integer. But, since the value of e is between values of 2 and 3, we understand that e4 has to be somewhere between 24 = 16 and 34 = 81.
It turns out that e4 = 54.498. This equality can be stated in terms of the natural logarithm in the following way, which you can check by using the ln calculator:
ln 54.498 = 4.
Here are some examples of natural logarithm:
• ln 1 = 0 since e0 = 1
• ln 10 = 2.3026 since e2.3026 = 10
• ln 20 = 2.996 since e2.996 = 20
• ln 50 = 3.912 since e3.912 = 50
• ln 100 = 4.605 since e4.605 = 100.
Check out the correctness of the above results by using our natural log calculator and the exponent calculator. In order to get a better grasp of the interplay between the exponential and logarithm functions, you may want to check out our exponential and logarithm calculators.
Other ways to denote the natural logarithm
One way of denoting the natural logarithm is loge. This is the same as, say, when we write the logarithm to the base two as log2.
But, a vastly more common way to write the natural logarithm is ln, which is an abbreviation of the Latin expression logarithmus naturalis, the name the natural logarithm was given when the Latin language was still the lingua franca of science.
There is also a third way of writing the natural logarithm: log. This notation is somewhat problematic though, as it is often mistaken for the logarithm to the base 10, although this is the syntax many software implementations of natural logarithm use, so be careful!
What's so natural about the natural logarithm?
Why exactly does ln x deserve to be called natural? Maybe the most important property of the natural logarithm is that it is the inverse function of the exponential function ex, the only function whose rate of change, or the derivative, is precisely again itself: (ex)' = ex.
In simpler words, the exponential function ex governs its own rate of change, which in some sense makes it self-sufficient and not dependent on any other function to define the way it changes. Exactly this property makes both ex and its inverse function ln x the natural choice when describing many real-world phenomena.
The natural log graph
Another interesting property of the natural logarithm is the way it changes its values as the argument x increases. One way of expressing this is by stating that the derivative of the natural logarithm is inversely proportional to its value x, which can be written as (ln x)' = 1/x.
You can also observe this property by looking at the graph of the natural logarithm. Although it increases as the value of x increases, the rate of growth is getting smaller and smaller as x approaches higher and higher values:

Where did the number e come from
At first glance, you wouldn't say that the number e bears any importance to the endeavors of humans or nature. But this is not so! It happens that this number is one of the most important constants in mathematics, so much so that it deserves a proper name. It is called either Euler's number or Napier's constant, depending on whom of these two great mathematicians one wants to attribute its discovery.
Nevertheless, it seems that Leonhard Euler (1707 - 1783) did get more credit, based on the fact that the very letter Euler used to denote this constant is how we denoted it today. Although Euler was the first to calculate e to a significant number of decimal places, he wasn't the first one to discover it: read more about it in the next paragraph.

How to make e amount of money
Swiss mathematician Jacob Bernoulli (1654 - 1705) stumbled upon the existence of the number e when tackling the problem of compound interest. Let us first understand the idea behind simple interest. For a given initial sum of money, let's say 1 USD, you want to know how much will you have after one year has passed if an interest of 100% is credited only once, and at the end of the year? The answer is easy: 2 USD.

But, with compound interest, things get a bit more complicated. For example, if the same interest of 100% is now split into two equal parts of 50% and credited twice, 50% at the end of first six months, and another 50% at the end of the year, then the final yield is obtained by using the formula
1*(1 + 1/2)2 = 2.25 USD.
Furthermore, if the interest of 100% is split in weekly lumps, you would have the final yield of
1*(1 + 1/52)52 = 2.692 USD.
Bernoulli asked a simple question: what would happen if compounding was continuous? In other words, what would be the final yield if the interest rate of 100% is split into infinite parts, each credited at the end of an infinitely short period of time? To see in more detail how continuous and other types of compounding work, you may want to check out our investment calculator.
This problem of continuous compound interest, stated mathematically, boils down to the challenge of calculating the limit of (1 + 1/n)n as n approaches infinity. It turns out that the result is precisely the number e! Moreover, the above expression may be used as a way to define e. To answer the Bernoulli's question: with continuous compounding the initial dollar would yield precisely e = 2.718281828 USD at the end of the year!
The real-world importance of ln 2 and other natural logarithms
The easiest natural logarithms to calculate are:
ln 1 = 0 since e0 = 1, and
ln e = 1 since e1 = e.
But, presumably the most important natural logarithm is the one that calculates the value of a number between 1 and e, which turns out to be the number 2. Using the natural log calculator we get
ln 2 = 0.6931.
It turns out that ln 2 is also equal to the alternating sum of reciprocals of all natural numbers:
ln 2 = 1 – 1/2 + 1/3 – 1/4 + 1/5 – 1/6 + ....
At first glance, it appears that this number has no particular importance whatsoever. But, ln 2, as obscure as it may seem, appears in some pretty significant and at first glance unrelated real-world problems.
For example, it has its role in the formula for the half-life of radioactively decaying matter, or in the calculation of time needed to double the initial amount of money, if a fixed rate is applied over a given time.
So, if you have 1,000 USD in your bank account, and the bank provides an r = 7% per annum interest rate, you may want to ask yourself how long it will take to double my initial amount? Well, this is where ln 2 comes into play: the natural logarithm formula that calculates the time needed is (100 * ln 2)/r, which can be simplified to the approximate value of 70/r. Besides 70, the number 72 is used even more often for this purpose, because it has more divisors: check out the rule of 72 calculator!
Therefore, in the case of r = 7%, you would get 70/7 = 10 years as an approximate time needed for your initial sum of money to double. Similarly, one can get analogous formulas for the time needed for the initial quantity to triple, quadruple, or n-tuple, given a fixed rate of growth over time.
Other applications of the natural logarithm
From the previous paragraph, we may conclude that natural logarithms occur in every process with a period-related, constant growth or decay of some quantifiable phenomenon.
Apart from already mentioned examples of radioactive decay and the problem of yield with a fixed interest rate, natural logarithms appear when calculating the bacterial, animal and plant population growth and decay, decay rates of a charged capacitor, or the temperature change of an object.

The VP of Sales just announced the company closed a major deal that is 100x larger than any other previous contract. The excitement pours over you, you can finally expense that Herman-Miller chair! However, you quickly realize you’ve never tested the production application at that 100x scale before. What do you do?
Scaling a web application is an exciting, and sometimes nerve-wracking problem. PHP buys us a lot of affordances, but we still need to think like engineers to make things scale in a maintainable, and affordable, manner.
We’ll walk through this hypothetical scenario together, taking time to explore options and tradeoffs for major decisions. These topics will include:
* Effective caching
* Keeping your database performing efficiently
* Tradeoffs of moving to microservices
* Security and safety measures
Most importantly, we’ll explore how to know when, and if, it is time for any of these things. Even how we can defer some decisions to keep our team working efficiently. For that, we’ll need to learn:
* How to add and review telemetry for our application
* How to determine key metrics we can know when we’re in trouble
* How to collaborate with the business for best success
Buckle up, because we’re going from zero to web scale in one talk!

C# 预处理器指令
预处理器指令指导编译器在实际编译开始之前对信息进行预处理。
所有的预处理器指令都是以 # 开始。且在一行上，只有空白字符可以出现在预处理器指令之前。预处理器指令不是语句，所以它们不以分号（;）结束。
C# 编译器没有一个单独的预处理器，但是，指令被处理时就像是有一个单独的预处理器一样。在 C# 中，预处理器指令用于在条件编译中起作用。与 C 和 C++ 不同指令不用，它们不是用来创建宏。一个预处理器指令必须是该行上的唯一指令。
C# 预处理器指令列表
下表列出了 C# 中可用的预处理器指令：
预处理器指令 描述
#define 它用于定义一系列成为符号的字符。
#undef 它用于取消定义符号。
#if 它用于测试符号是否为真。
#else 它用于创建复合条件指令，与 #if 一起使用。
#elif 它用于创建复合条件指令。
#endif 指定一个条件指令的结束。
#line 它可以让您修改编译器的行数以及（可选地）输出错误和警告的文件名。
#error 它允许从代码的指定位置生成一个错误。
#warning 它允许从代码的指定位置生成一级警告。
#region 它可以让您在使用 Visual Studio Code Editor 的大纲特性时，指定一个可展开或折叠的代码块。
#endregion 它标识着 #region 块的结束。
#define 预处理器
#define 预处理器指令创建符号常量。
#define 允许您定义一个符号，这样，通过使用符号作为传递给 #if 指令的表达式，表达式将返回 true。它的语法如下：
#define symbol
下面的程序说明了这点：
#define PI
using System;
namespace PreprocessorDAppl
{
class Program
{
static void Main(string[] args)
{
#if (PI)
Console.WriteLine("PI is defined");
#else
Console.WriteLine("PI is not defined");
#endif
Console.ReadKey();
}
}
}
当上面的代码被编译和执行时，它会产生下列结果：
PI is defined
条件指令
您可以使用 #if 指令来创建一个条件指令。条件指令用于测试符号是否为真。如果为真，编译器会执行 #if 和下一个指令之间的代码。
条件指令的语法：
#if symbol [operator symbol]...
其中，symbol 是要测试的符号名称。您也可以使用 true 和 false，或在符号前放置否定运算符。
运算符符号是用于评价符号的运算符。可以运算符可以是下列运算符之一：
• == (equality)
• != (inequality)
• && (and)
• || (or)
您也可以用括号把符号和运算符进行分组。条件指令用于在调试版本或编译指定配置时编译代码。一个以 #if 指令开始的条件指令，必须显示地以一个 #endif 指令终止。
下面的程序演示了条件指令的用法：
#define DEBUG
#define VC_V10
using System;
public class TestClass
{
public static void Main()
{
#if (DEBUG && !VC_V10)
Console.WriteLine("DEBUG is defined");
#elif (!DEBUG && VC_V10)
Console.WriteLine("VC_V10 is defined");
#elif (DEBUG && VC_V10)
Console.WriteLine("DEBUG and VC_V10 are defined");
#else
Console.WriteLine("DEBUG and VC_V10 are not defined");
#endif
Console.ReadKey();
}
}
当上面的代码被编译和执行时，它会产生下列结果：
DEBUG and VC_V10 are defined

Don’t Know What The Word Means? Ask Cortana
As Microsoft and the Cortana team continue to refine the powerful AI and assistant, more features are slowly popping up online. A new one noticed by numerous people in our audience is definitions, powered by Oxford Dictionaries.
Load up Cortana and directly ask her ‘What does _____ mean?’ alternatively, ‘What is the meaning of ____?’ and the personal assistant from 500 years in the future pulls up a nice little card, complete with the word category and multiple definitions while exclaiming “I’ve found the meaning of…”.
Additionally, there is on occasion a ‘See more’ link near the bottom, which then opens up the corresponding page on the Oxford site. Some definitions also come up under Bing’s dictionary as well so your results may vary.
Although not a groundbreaking feature, using Cortana to ask quickly what a word means is certainly easier than hunting for that app, launching it, typing in a word and doing the lookup. This tool should also be particularly useful for those learning English as a second language, and we presume this word-lookup feature expands to other languages in the future.
Is looking up words a useful feature for you? How do you think Microsoft could make it better?

Abstract
Disclosed is a method to integrate dual (or multiple) text search engines to a Content Management System (CMS) on a relational database in a manner which reduces limitations and improves performance.

This is the abbreviated version, containing approximately 36% of the total text.

Integrating Heterogeneous Text Search Engines For A Content Management System
A content management system (CMS) supports relational databases, sometimes more than one at a time, and the CMS on each database is integrated with its own unique text search engine/server. There are two separate databases; hence, the CMS on one database is independent from another.
A CMS on a relational database integrates with only one text search engine, resulting in search engine related limitations for search performance, dependability, and search features such as proximity search, fuzzy search, etc. based on the characteristics and capabilities provided by this search engine of the text search server.
To minimize these limitations, a method for integration of dual (or multiple) text search engines to the CMS on a relational database is herein disclosed.
The relational database, as a client of the text search server, has evolved to support both the text search server and Enterprise Content Manager Text Search (ECMTS) servers for text search engines. The new ECMTS server can also be stand-alone as a remote server communicating with a relational database via Transmission Control Protocol/Internet Protocol (TCP/IP) while the text search server can only be integrated with a relational database on the same computer box. The ECMTS being remote makes it possible to maintain the same indexing schedule for both the text search server and ECMTS. The CMS system administrator can configure a CMS text searchable item type with text indexes on both text search engines, and then index on both search engines after the search contents are inserted into the text searchable attributes (columns) or the search documents are imported into the remote repository.
The advantages of the CMS integration with dual indexing/search engines are many. First, the text indexing is an extensive operation; it requires a high Central Processing Unit (CPU) consumption. Since the new ECMTS server can be remote (i.e. separated from the computer box where the text search server resides), the indexing schedule can be maintained the same for both the text search server and ECMTS. The method of dual text search engines disclosed herein allows the same contents under the same CMS item type to be text-indexed in at least two sets, one for text search server, and the other for ECMTS. If one set is down, then the CMS System Administrator can switch to turn on the active flag for the other engine so that all search applications are directed to the active search engine. Second, even when both search engines are running, switching the active flag from one to the other allows user search applications to switch the search from one set of text indexes to another. A relational database
allows one search engine to be active at a time. This allows search engines to complement one another and thus minimizes the search limitations resulting from each search engine. In addition, the method adapts to users'...

1. The problem statement, all variables and given/known data
hey, it's been on my wish list for some time, i have decided to teach my self diffrential equal, rather than waiting to be taught at school, after having some exposure through vibrations and circuits.
so i got a book and i started to learn, the question came to be;
[tex]x^{3}[/tex] [tex]\frac{dy}{dx}[/tex] = y
2. The attempt at a solution
so i solve it by seperation of variable and arrived at the answer of
y=[tex]e^{-.5x^{2}+c}[/tex]
i am afride it is wrong, or am i just confused.

try and show your working, and note you can put a whole equation in tex tags
[tex]x^3 \frac{dy}{dx} = y[/tex]
did you separate like below?
[tex] \frac{dy}{y} = \frac{dx}{x^3} [/tex]

Then you've lost a sign.
If [itex]dy/y= dx/x^3= x^{-3}dx[/itex] then
[tex]ln(y)= -(1/2)x^{-2}+ C[/tex]
and so
[tex]y= e^{-.5x^{-2}+ C[/tex]
It should be [itex]x^{-2}[/itex] in the exponent, not [itex]x^2[/itex].

Building a dynamic JSON Request body with n objects in an array
beitlichebeitliche Posts: 3
Hello,
I have a use case that I'm trying to implement in SOATest and am running into a wall.
I have a Service1 that returns n number of Account objects. There are a varying amount of accounts that could be returned for a given request as that user may have more or less accounts than another.
I have a second service, Service2, that takes a structured request of n Account objects and AccountId is an integer that is required on all Accounts passed.
What I am attempting to do is extract AccountIds from the Service1 response and then build out a request to Service2 in a dynamic fashion. I have tried using a JSON Databank to extract the AccountIds from Service1 and then paramaterized that to the Service2 request but it just pastes ALL the AccountIds into a single AccountId field. Is there any way to dynamically create an array of objects using SOATest, in memory?
See below for samples.
Service1 Response:
{
"AccountSummaryList":[
{
"AccountId":"111111111",
"AccountType:"BLAHBLAH"
},
{
"AccountId":"22222",
"AccountType:"BLAHBLAH"
},
{.....}
]
}
Service2 Request:
{
"Accounts":[
{
"AccountId":111111,
"otherdetails":"blahblah"
},
{
"AccountId":222222,
"otherdetails":"blahblah"
}
]
}

I second this question!

Hi Beitliche,
There are possibly more elegant implementations, but off the top of my head I would use an XML data bank to extract all of the element values to a Writable data source.
Modify the Xpath to grab all values not just a single one.
Once written into a data source you can then use the
context.getValues("writable_name","column_name") method to move the values to an arraylist and then simply loop the values while adding the tags. You would then have your xml body.
This Example requires the use of a test suite variable. (Double click the test suite and navigate to then variable tab)
Example script:
import com.parasoft.api.*;
public void compareASC(Object input, ScriptingContext context)
{
String fullString = "";
ArrayList<String> list = context.getValues("data","values");
for(int i = 0; i < list.size() ; i++)
{
String a = list.get(i);
a = "<test>" + a + "</test>";
fullString += a;
}
context.setValue("x", fullString);
}
Now you can reference the variable "x" to get the values.
In your messaging client, switch to "literal mode"(otherwise the background encoding will change the '<' & '>') and reference the variable with ${variable_name} .
The scenario

Here is some general information.
It is common for to take elements/objects/arrays from a response and then reuse them in a subsequent request. Typically, you would do the following:
1. Extract the desired element/object/array that you want to reuse to a data bank column. In the data bank, click Modify to open the Modify Selected XPath settings dialog. Make sure "Entire element" is selected and not "Content only".
2. In the subsequent request, replace the desired element/property/item with the data bank column. In the Form view, you would right-click the on the element you want to replace then click "Replace with Data Source Value", select Data Bank, choose your data bank column, then click Finish.
What I mention applies to both JSON and XML. For JSON, you would be using a JSON Data Bank and the Form JSON view. For XML, you would be using an XML Data Bank and the Form Input view.
Sometimes using the extraction as-is is desired. However, in some scenarios you want to transform the data in some way before reusing it. This could be accomplished using scripting (Extension Tool) or using XSL (XSLT Tool). Some simple transformations, like removing or appending values, can be applied by Data Bank itself by enabling the "Allow alteration" box under Options (collapsed by default).
Ramiro's response is one such example where scripting can be used to transform extracted values.

Hello,
Thank you for your responses.
@benken_parasoft I have tried the above and am not seeing the intended outcome.
Here is a sample of the response that I am extracting the AccountId values from:
From this response I have the following data bank/xpath setup. As you can see it's set in "AccountId, ####" format. Which I would expect to be able to use.
In the secondary request I am trying to build here is a sample of the form JSON (There will be other elements, I'm just trying to get this one working for now as a POC).
I have tried setting the Replacement at the Accounts, and Item[0] level (as those are the only two that allow it. I cannot add a replacement at the AccountId level). I receive the following error when attempting this.
Please advise if I am missing something but as far as I can tell SOATest does not natively support the use case for which I am trying. Short of coding up an extension to build this request I cannot see a path forward.
Thanks!

The steps I described are for extracting the entire array and then replacing the entire array element. If you want to do that then you would extract the value of the AccountSummaryList array and then replace the Accounts array in the subsequent test.
As mentioned, more steps or different steps would be required if you need to transform the contents of the array being extracted (change/add/remove values or rename things). As mentioned, this may have involve scripting or XSL. Ramiro gives one such example. Please note that if you follow Ramiro's example, he's not extracting the entire array but the contents to a Writable Data Source and using scripting to construct the desired result (which is a different approach than what I describe but also fine).

This class represents a string-like object whose value is a mutable sequence of characters.
In this section:
Although StringBuilder and String both represent sequences of characters, they are implemented differently. String is an immutable type. That is, each operation that appears to modify a String object actually creates a new string.
For example, the call to the String.Concat method in the following C# example appears to change the value of a string variable named value. In fact, the Concat method returns a value object that has a different value and address from the value object that was passed to the method. Note that the example must be compiled using the /unsafe compiler option.
using System;
public class Example
{
public unsafe static void Main()
{
string value = "This is the first sentence" + ".";
fixed (char* start = value)
{
value = String.Concat(value, "This is the second sentence. ");
fixed (char* current = value)
{
Console.WriteLine(start == current);
}
}
}
}
// The example displays the following output:
// False
For routines that perform extensive string manipulation (such as apps that modify a string numerous times in a loop), modifying a string repeatedly can exact a significant performance penalty. The alternative is to use StringBuilder, which is a mutable string class. Mutability means that once an instance of the class has been created, it can be modified by appending, removing, replacing, or inserting characters. A StringBuilder object maintains a buffer to accommodate expansions to the string. New data is appended to the buffer if room is available; otherwise, a new, larger buffer is allocated, data from the original buffer is copied to the new buffer, and the new data is then appended to the new buffer.
System_CAPS_importantImportant
Although the StringBuilder class generally offers better performance than the String class, you should not automatically replace String with StringBuilder whenever you want to manipulate strings. Performance depends on the size of the string, the amount of memory to be allocated for the new string, the system on which your app is executing, and the type of operation. You should be prepared to test your app to determine whether StringBuilder actually offers a significant performance improvement.
Consider using the String class under these conditions:
• When the number of changes that your app will make to a string is small. In these cases, StringBuilder might offer negligible or no performance improvement over String.
• When you are performing a fixed number of concatenation operations, particularly with string literals. In this case, the compiler might combine the concatenation operations into a single operation.
• When you have to perform extensive search operations while you are building your string. The StringBuilder class lacks search methods such as IndexOf or StartsWith. You'll have to convert the StringBuilder object to a String for these operations, and this can negate the performance benefit from using StringBuilder. For more information, see the Searching the text in a StringBuilder object section.
Consider using the StringBuilder class under these conditions:
• When you expect your app to make an unknown number of changes to a string at design time (for example, when you are using a loop to concatenate a random number of strings that contain user input).
• When you expect your app to make a significant number of changes to a string.
The StringBuilder.Length property indicates the number of characters the StringBuilder object currently contains. If you add characters to the StringBuilder object, its length increases until it equals the size of the StringBuilder.Capacity property, which defines the number of characters that the object can contain. If the number of added characters causes the length of the StringBuilder object to exceed its current capacity, new memory is allocated, the value of the Capacity property is doubled, new characters are added to the StringBuilder object, and its Length property is adjusted. Additional memory for the StringBuilder object is allocated dynamically until it reaches the value defined by the StringBuilder.MaxCapacity property. When the maximum capacity is reached, no further memory can be allocated for the StringBuilder object, and trying to add characters or expand it beyond its maximum capacity throws either an ArgumentOutOfRangeException or an OutOfMemoryException exception.
The following example illustrates how a StringBuilder object allocates new memory and increases its capacity dynamically as the string assigned to the object expands. The code creates a StringBuilder object by calling its default (parameterless) constructor. The default capacity of this object is 16 characters, and its maximum capacity is more than 2 billion characters. Appending the string "This is a sentence." results in a new memory allocation because the string length (19 characters) exceeds the default capacity of the StringBuilder object. The capacity of the object doubles to 32 characters, the new string is added, and the length of the object now equals 19 characters. The code then appends the string "This is an additional sentence." to the value of the StringBuilder object 11 times. Whenever the append operation causes the length of the StringBuilder object to exceed its capacity, its existing capacity is doubled and the Append operation succeeds.
using System;
using System.Reflection;
using System.Text;
public class Example
{
public static void Main()
{
StringBuilder sb = new StringBuilder();
ShowSBInfo(sb);
sb.Append("This is a sentence.");
ShowSBInfo(sb);
for (int ctr = 0; ctr <= 10; ctr++) {
sb.Append("This is an additional sentence.");
ShowSBInfo(sb);
}
}
private static void ShowSBInfo(StringBuilder sb)
{
foreach (var prop in sb.GetType().GetProperties()) {
if (prop.GetIndexParameters().Length == 0)
Console.Write("{0}: {1:N0} ", prop.Name, prop.GetValue(sb));
}
Console.WriteLine();
}
}
// The example displays the following output:
// Capacity: 16 MaxCapacity: 2,147,483,647 Length: 0
// Capacity: 32 MaxCapacity: 2,147,483,647 Length: 19
// Capacity: 64 MaxCapacity: 2,147,483,647 Length: 50
// Capacity: 128 MaxCapacity: 2,147,483,647 Length: 81

// Capacity: 256 MaxCapacity: 2,147,483,647 Length: 143
// Capacity: 256 MaxCapacity: 2,147,483,647 Length: 174
// Capacity: 256 MaxCapacity: 2,147,483,647 Length: 205
// Capacity: 256 MaxCapacity: 2,147,483,647 Length: 236
// Capacity: 512 MaxCapacity: 2,147,483,647 Length: 267
// Capacity: 512 MaxCapacity: 2,147,483,647 Length: 298
// Capacity: 512 MaxCapacity: 2,147,483,647 Length: 329
// Capacity: 512 MaxCapacity: 2,147,483,647 Length: 360
The default capacity of a StringBuilder object is 16 characters, and its default maximum capacity is Int32.MaxValue. These default values are used if you call the StringBuilder() and StringBuilder(String) constructors.
You can explicitly define the initial capacity of a StringBuilder object in the following ways:
• By calling any of the StringBuilder constructors that includes a capacity parameter when you create the object.
• By explicitly assigning a new value to the StringBuilder.Capacity property to expand an existing StringBuilder object. Note that the property throws an exception if the new capacity is less than the existing capacity or greater than the StringBuilder object's maximum capacity.
• By calling the StringBuilder.EnsureCapacity method with the new capacity. The new capacity must not be greater than the StringBuilder object's maximum capacity. However, unlike an assignment to the Capacity property, EnsureCapacity does not throw an exception if the desired new capacity is less than the existing capacity; in this case, the method call has no effect.
If the length of the string assigned to the StringBuilder object in the constructor call exceeds either the default capacity or the specified capacity, the Capacity property is set to the length of the string specified with the value parameter.
You can explicitly define the maximum capacity of a StringBuilder object by calling the StringBuilder(Int32, Int32) constructor. You can't change the maximum capacity by assigning a new value to the MaxCapacity property, because it is read-only.
As the previous section shows, whenever the existing capacity is inadequate, additional memory is allocated and the capacity of a StringBuilder object doubles up to the value defined by the MaxCapacity property.
In general, the default capacity and maximum capacity are adequate for most apps. You might consider setting these values under the following conditions:
• If the eventual size of the StringBuilder object is likely to grow exceedingly large, typically in excess of several megabytes. In this case, there may be some performance benefit from setting the initial Capacity property to a significantly high value to eliminate the need for too many memory reallocations.
• If your app is running on a system with limited memory. In this case, you may want to consider setting the MaxCapacity property to less than Int32.MaxValue if your app is handling large strings that may cause it to execute in a memory-constrained environment.
You instantiate a StringBuilder object by calling one of its six overloaded class constructors, which are listed in the following table. Three of the constructors instantiate a StringBuilder object whose value is an empty string, but set its Capacity and MaxCapacity values differently. The remaining three constructors define a StringBuilder object that has a specific string value and capacity. Two of the three constructors use the default maximum capacity of Int32.MaxValue, whereas the third allows you to set the maximum capacity.

The following example uses three of these constructor overloads to instantiate StringBuilder objects.
using System;
using System.Text;
public class Example
{
public static void Main()
{
string value = "An ordinary string";
int index = value.IndexOf("An ") + 3;
int capacity = 0xFFFF;
// Instantiate a StringBuilder from a string.
StringBuilder sb1 = new StringBuilder(value);
ShowSBInfo(sb1);
// Instantiate a StringBuilder from string and define a capacity.
StringBuilder sb2 = new StringBuilder(value, capacity);
ShowSBInfo(sb2);
// Instantiate a StringBuilder from substring and define a capacity.
StringBuilder sb3 = new StringBuilder(value, index,
value.Length - index,
capacity );
ShowSBInfo(sb3);
}
public static void ShowSBInfo(StringBuilder sb)
{
Console.WriteLine("\nValue: {0}", sb.ToString());
foreach (var prop in sb.GetType().GetProperties()) {
if (prop.GetIndexParameters().Length == 0)
Console.Write("{0}: {1:N0} ", prop.Name, prop.GetValue(sb));
}
Console.WriteLine();
}
}
// The example displays the following output:
// Value: An ordinary string
// Capacity: 18 MaxCapacity: 2,147,483,647 Length: 18
//
// Value: An ordinary string
// Capacity: 65,535 MaxCapacity: 2,147,483,647 Length: 18
//
// Value: ordinary string
// Capacity: 65,535 MaxCapacity: 2,147,483,647 Length: 15
Most of the methods that modify the string in a StringBuilder instance return a reference to that same instance. This enables you to call StringBuilder methods in two ways:
• You can make individual method calls and ignore the return value, as the following example does.
using System;
using System.Text;
public class Example
{
public static void Main()
{
StringBuilder sb = new StringBuilder();
sb.Append("This is the beginning of a sentence, ");
sb.Replace("the beginning of ", "");
sb.Insert(sb.ToString().IndexOf("a ") + 2, "complete ");
sb.Replace(",", ".");
Console.WriteLine(sb.ToString());
}
}
// The example displays the following output:
// This is a complete sentence.
• You can make a series of method calls in a single statement. This can be convenient if you want to write a single statement that chains successive operations. The following example consolidates three method calls from the previous example into a single line of code.
using System;
using System.Text;
public class Example
{
public static void Main()
{
StringBuilder sb = new StringBuilder("This is the beginning of a sentence, ");
sb.Replace("the beginning of ", "").Insert(sb.ToString().IndexOf("a ") + 2,
"complete ").Replace(",", ".");
Console.WriteLine(sb.ToString());
}
}
// The example displays the following output:
// This is a complete sentence.
You can use the methods of the StringBuilder class to iterate, add, delete, or modify characters in a StringBuilder object.
You can access the characters in a StringBuilder object by using the StringBuilder.Chars property. In C#, Chars is an indexer; in Visual Basic, it is the default property of the StringBuilder class. This enables you to set or retrieve individual characters by using their index only, without explicitly referencing the Chars property. Characters in a StringBuilder object begin at index 0 (zero) and continue to index Length - 1.
The following example illustrates the Chars property. It appends ten random numbers to a StringBuilder object, and then iterates each character. If the character's Unicode category is UnicodeCategory.DecimalDigitNumber, it decreases the number by 1 (or changes the number to 9 if its value is 0). The example displays the contents of the StringBuilder object both before and after the values of individual characters were changed.
using System;
using System.Globalization;
using System.Text;
public class Example
{
public static void Main()
{
Random rnd = new Random();
StringBuilder sb = new StringBuilder();
// Generate 10 random numbers and store them in a StringBuilder.
for (int ctr = 0; ctr <= 9; ctr++)
sb.Append(rnd.Next().ToString("N5"));
Console.WriteLine("The original string:");
Console.WriteLine(sb.ToString());
// Decrease each number by one.
for (int ctr = 0; ctr < sb.Length; ctr++) {
if (Char.GetUnicodeCategory(sb[ctr]) == UnicodeCategory.DecimalDigitNumber) {
int number = (int) Char.GetNumericValue(sb[ctr]);
number--;
if (number < 0) number = 9;
sb[ctr] = number.ToString()[0];
}
}
Console.WriteLine("\nThe new string:");
Console.WriteLine(sb.ToString());
}
}
// The example displays the following output:
// The original string:
// 1,457,531,530.00000940,522,609.000001,668,113,564.000001,998,992,883.000001,792,660,834.00
// 000101,203,251.000002,051,183,075.000002,066,000,067.000001,643,701,043.000001,702,382,508
// .00000
//
// The new string:
// 0,346,420,429.99999839,411,598.999990,557,002,453.999990,887,881,772.999990,681,559,723.99
// 999090,192,140.999991,940,072,964.999991,955,999,956.999990,532,690,932.999990,691,271,497
// .99999
The StringBuilder class includes the following methods for expanding the contents of a StringBuilder object:
• The Append method appends a string, a substring, a character array, a portion of a character array, a single character repeated multiple times, or the string representation of a primitive data type to a StringBuilder object.
• The AppendLine method appends a line terminator or a string along with a line terminator to a StringBuilder object.
• The AppendFormat method appends a to a StringBuilder object. The string representations of objects included in the result string can reflect the formatting conventions of the current system culture or a specified culture.
• The Insert method inserts a string, a substring, multiple repetitions of a string, a character array, a portion of a character array, or the string representation of a primitive data type at a specified position in the StringBuilder object. The position is defined by a zero-based index.
The following example uses the Append, AppendLine, AppendFormat, and Insert methods to expand the text of a StringBuilder object.
using System;
using System.Text;
public class Example
{
public static void Main()
{
// Create a StringBuilder object with no text.
StringBuilder sb = new StringBuilder();
// Append some text.
sb.Append('*', 10).Append(" Adding Text to a StringBuilder Object ").Append('*', 10);
sb.AppendLine("\n");
sb.AppendLine("Some code points and their corresponding characters:");
// Append some formatted text.
for (int ctr = 50; ctr <= 60; ctr++) {
sb.AppendFormat("{0,12:X4} {1,12}", ctr, Convert.ToChar(ctr));
sb.AppendLine();
}
// Find the end of the introduction to the column.
int pos = sb.ToString().IndexOf("characters:") + 11 +
Environment.NewLine.Length;
// Insert a column header.
sb.Insert(pos, String.Format("{2}{0,12:X4} {1,12}{2}", "Code Unit",
"Character", "\n"));
// Convert the StringBuilder to a string and display it.
Console.WriteLine(sb.ToString());
}
}
// The example displays the following output:
// ********** Adding Text to a StringBuilder Object **********
//
// Some code points and their corresponding characters:
//
// Code Unit Character
// 0032 2
// 0033 3
// 0034 4
// 0035 5
// 0036 6
// 0037 7
// 0038 8
// 0039 9
// 003A :
// 003B ;
// 003C <
The StringBuilder class includes methods that can reduce the size of the current StringBuilder instance. The Clear method removes all characters and sets the Length property to zero. The Remove method deletes a specified number of characters starting at a particular index position. In addition, you can remove characters from the end of a StringBuilder object by setting its Length property to a value that is less than the length of the current instance.
The following example removes some of the text from a StringBuilder object, displays its resulting capacity, maximum capacity, and length property values, and then calls the Clear method to remove all the characters from the StringBuilder object.
using System;
using System.Text;
public class Example
{
public static void Main()
{
StringBuilder sb = new StringBuilder("A StringBuilder object");
ShowSBInfo(sb);
// Remove "object" from the text.
string textToRemove = "object";
int pos = sb.ToString().IndexOf(textToRemove);
if (pos >= 0) {
sb.Remove(pos, textToRemove.Length);
ShowSBInfo(sb);
}
// Clear the StringBuilder contents.
sb.Clear();
ShowSBInfo(sb);
}
public static void ShowSBInfo(StringBuilder sb)
{
Console.WriteLine("\nValue: {0}", sb.ToString());
foreach (var prop in sb.GetType().GetProperties()) {
if (prop.GetIndexParameters().Length == 0)
Console.Write("{0}: {1:N0} ", prop.Name, prop.GetValue(sb));
}
Console.WriteLine();
}
}
// The example displays the following output:
// Value: A StringBuilder object
// Capacity: 22 MaxCapacity: 2,147,483,647 Length: 22
//
// Value: A StringBuilder
// Capacity: 22 MaxCapacity: 2,147,483,647 Length: 16
//
// Value:
// Capacity: 22 MaxCapacity: 2,147,483,647 Length: 0
The StringBuilder.Replace method replaces all occurrences of a character or a string in the entire StringBuilder object or in a particular character range. The following example uses the Replace method to replace all exclamation points (!) with question marks (?) in the StringBuilder object.
using System;
using System.Text;
public class Example
{
public static void Main()
{
StringBuilder MyStringBuilder = new StringBuilder("Hello World!");
MyStringBuilder.Replace('!', '?');
Console.WriteLine(MyStringBuilder);
}
}
// The example displays the following output:
// Hello World?
The StringBuilder class does not include methods similar to the String.Contains, String.IndexOf, and String.StartsWith methods provided by the String class, which allow you to search the object for a particular character or a substring. Determining the presence or starting character position of a substring requires that you search a String value by using either a string search method or a regular expression method. There are four ways to implement such searches, as the following table shows.
Technique
Pros
Cons
Search string values before adding them to the StringBuilder object.
Useful for determining whether a substring exists.
Cannot be used when the index position of a substring is important.
Call ToString and search the returned String object.
Easy to use if you assign all the text to a StringBuilder object, and then begin to modify it.
Cumbersome to repeatedly call ToString if you must make modifications before all text is added to the StringBuilder object.
You must remember to work from the end of the StringBuilder object's text if you're making changes.
Use the Chars property to sequentially search a range of characters.
Useful if you're concerned with individual characters or a small substring.
Cumbersome if the number of characters to search is large or if the search logic is complex.
Convert the StringBuilder object to a String object, and perform modifications on the String object.
Useful if the number of modifications is small.
Negates the performance benefit of the StringBuilder class if the number of modifications is large.
Let's examine these techniques in greater detail.
• If the goal of the search is to determine whether a particular substring exists (that is, if you aren't interested in the position of the substring), you can search strings before storing them in the StringBuilder object. The following example provides one possible implementation. It defines a StringBuilderFinder class whose constructor is passed a reference to a StringBuilder object and the substring to find in the string. In this case, the example tries to determine whether recorded temperatures are in Fahrenheit or Celsius, and adds the appropriate introductory text to the beginning of the StringBuilder object. A random number generator is used to select an array that contains data in either degrees Celsius or degrees Fahrenheit.
using System;
using System.Text;
public class Example
{
public static void Main()
{
Random rnd = new Random();
string[] tempF = { "47.6F", "51.3F", "49.5F", "62.3F" };
string[] tempC = { "21.2C", "16.1C", "23.5C", "22.9C" };
string[][] temps = { tempF, tempC };
StringBuilder sb = new StringBuilder();
var f = new StringBuilderFinder(sb, "F");
var baseDate = new DateTime(2013, 5, 1);
String[] temperatures = temps[rnd.Next(2)];
bool isFahrenheit = false;
foreach (var temperature in temperatures) {
if (isFahrenheit)
sb.AppendFormat("{0:d}: {1}\n", baseDate, temperature);
else
isFahrenheit = f.SearchAndAppend(String.Format("{0:d}: {1}\n",
baseDate, temperature));
baseDate = baseDate.AddDays(1);
}
if (isFahrenheit) {
sb.Insert(0, "Average Daily Temperature in Degrees Fahrenheit");
sb.Insert(47, "\n\n");
}
else {
sb.Insert(0, "Average Daily Temperature in Degrees Celsius");
sb.Insert(44, "\n\n");
}
Console.WriteLine(sb.ToString());
}
}
public class StringBuilderFinder
{
private StringBuilder sb;
private String text;
public StringBuilderFinder(StringBuilder sb, String textToFind)
{
this.sb = sb;
this.text = textToFind;
}
public bool SearchAndAppend(String stringToSearch)
{
sb.Append(stringToSearch);
return stringToSearch.Contains(text);
}
}
// The example displays output similar to the following:
// Average Daily Temperature in Degrees Celsius
//
// 5/1/2013: 21.2C
// 5/2/2013: 16.1C
// 5/3/2013: 23.5C
// 5/4/2013: 22.9C
• Call the StringBuilder.ToString method to convert the StringBuilder object to a String object. You can search the string by using methods such as String.LastIndexOf or String.StartsWith, or you can use regular expressions and the Regex class to search for patterns. Because both StringBuilder and String objects use UTF-16 encoding to store characters, the index positions of characters, substrings, and regular expression matches are the same in both objects. This enables you to use StringBuilder methods to make changes at the same position at which that text is found in the String object.
System_CAPS_noteNote
If you adopt this approach, you should work from the end of the StringBuilder object to its beginning so that you don't have to repeatedly convert the StringBuilder object to a string.
The following example illustrates this approach. It stores four occurrences of each letter of the English alphabet in a StringBuilder object. It then converts the text to a String object and uses a regular expression to identify the starting position of each four-character sequence. Finally, it adds an underscore before each four-character sequence except for the first sequence, and converts the first character of the sequence to uppercase.
using System;
using System.Text;
using System.Text.RegularExpressions;
public class Example
{
public static void Main()
{
// Create a StringBuilder object with 4 successive occurrences
// of each character in the English alphabet.
StringBuilder sb = new StringBuilder();
for (ushort ctr = (ushort)'a'; ctr <= (ushort) 'z'; ctr++)
sb.Append(Convert.ToChar(ctr), 4);
// Create a parallel string object.
String sbString = sb.ToString();
// Determine where each new character sequence begins.
String pattern = @"(\w)\1+";
MatchCollection matches = Regex.Matches(sbString, pattern);
// Uppercase the first occurrence of the sequence, and separate it
// from the previous sequence by an underscore character.
for (int ctr = matches.Count - 1; ctr >= 0; ctr--) {
Match m = matches[ctr];
sb[m.Index] = Char.ToUpper(sb[m.Index]);
if (m.Index > 0) sb.Insert(m.Index, "_");
}
// Display the resulting string.
sbString = sb.ToString();
int line = 0;
do {
int nChars = line * 80 + 79 <= sbString.Length ?
80 : sbString.Length - line * 80;
Console.WriteLine(sbString.Substring(line * 80, nChars));
line++;
} while (line * 80 < sbString.Length);
}
}
// The example displays the following output:
// Aaaa_Bbbb_Cccc_Dddd_Eeee_Ffff_Gggg_Hhhh_Iiii_Jjjj_Kkkk_Llll_Mmmm_Nnnn_Oooo_Pppp_
// Qqqq_Rrrr_Ssss_Tttt_Uuuu_Vvvv_Wwww_Xxxx_Yyyy_Zzzz
• Use the StringBuilder.Chars property to sequentially search a range of characters in a StringBuilder object. This approach may not be practical if the number of characters to be searched is large or the search logic is particularly complex.
The following example is identical in functionality to the previous example but differs in implementation. It uses the Chars property to detect when a character value has changed, inserts an underscore at that position, and converts the first character in the new sequence to uppercase.
using System;
using System.Text;
public class Example
{
public static void Main()
{
// Create a StringBuilder object with 4 successive occurrences
// of each character in the English alphabet.
StringBuilder sb = new StringBuilder();
for (ushort ctr = (ushort) 'a'; ctr <= (ushort) 'z'; ctr++)
sb.Append(Convert.ToChar(ctr), 4);
// Iterate the text to determine when a new character sequence occurs.
int position = 0;
Char current = '\u0000';
do {
if (sb[position] != current) {
current = sb[position];
sb[position] = Char.ToUpper(sb[position]);
if (position > 0)
sb.Insert(position, "_");
position += 2;
}
else {
position++;
}
} while (position <= sb.Length - 1);
// Display the resulting string.
String sbString = sb.ToString();
int line = 0;
do {
int nChars = line * 80 + 79 <= sbString.Length ?
80 : sbString.Length - line * 80;
Console.WriteLine(sbString.Substring(line * 80, nChars));
line++;
} while (line * 80 < sbString.Length);
}
}
// The example displays the following output:
// Aaaa_Bbbb_Cccc_Dddd_Eeee_Ffff_Gggg_Hhhh_Iiii_Jjjj_Kkkk_Llll_Mmmm_Nnnn_Oooo_Pppp_
// Qqqq_Rrrr_Ssss_Tttt_Uuuu_Vvvv_Wwww_Xxxx_Yyyy_Zzzz
• Store all the unmodified text in the StringBuilder object, call the StringBuilder.ToString method to convert the StringBuilder object to a String object, and perform the modifications on the String object. You can use this approach if you have only a few modifications; otherwise, the cost of working with immutable strings may negate the performance benefits of using a StringBuilder object.
The following example is identical in functionality to the previous two examples but differs in implementation. It creates a StringBuilder object, converts it to a String object, and then uses a regular expression to perform all remaining modifications on the string. The Regex.Replace(String, String, MatchEvaluator) method uses a lambda expression to perform the replacement on each match.
using System;
using System.Text;
using System.Text.RegularExpressions;
public class Example
{
public static void Main()
{
// Create a StringBuilder object with 4 successive occurrences
// of each character in the English alphabet.
StringBuilder sb = new StringBuilder();
for (ushort ctr = (ushort)'a'; ctr <= (ushort) 'z'; ctr++)
sb.Append(Convert.ToChar(ctr), 4);
// Convert it to a string.
String sbString = sb.ToString();
// Use a regex to uppercase the first occurrence of the sequence,
// and separate it from the previous sequence by an underscore.
string pattern = @"(\w)(\1+)";
sbString = Regex.Replace(sbString, pattern,
m => (m.Index > 0 ? "_" : "") +
m.Groups[1].Value.ToUpper() +
m.Groups[2].Value);
// Display the resulting string.
int line = 0;
do {
int nChars = line * 80 + 79 <= sbString.Length ?
80 : sbString.Length - line * 80;
Console.WriteLine(sbString.Substring(line * 80, nChars));
line++;
} while (line * 80 < sbString.Length);
}
}
// The example displays the following output:
// Aaaa_Bbbb_Cccc_Dddd_Eeee_Ffff_Gggg_Hhhh_Iiii_Jjjj_Kkkk_Llll_Mmmm_Nnnn_Oooo_Pppp_
// Qqqq_Rrrr_Ssss_Tttt_Uuuu_Vvvv_Wwww_Xxxx_Yyyy_Zzzz
You must convert the StringBuilder object to a String object before you can pass the string represented by the StringBuilder object to a method that has a String parameter or display it in the user interface. You perform this conversion by calling the StringBuilder.ToString method. For an illustration, see the previous example, which calls the ToString method to convert a StringBuilder object to a string so that it can be passed to a regular expression method.
Notes to Callers:
In the.NET Framework 4 and the .NET Framework 4.5, when you instantiate the StringBuilder object by calling the StringBuilder(Int32, Int32) constructor, both the length and the capacity of the StringBuilder instance can grow beyond the value of its MaxCapacity property. This can occur particularly when you call the Append and AppendFormat methods to append small strings.
The following example shows how to call many of the methods defined by the StringBuilder class.
using System;
using System.Text;
public sealed class App
{
static void Main()
{
// Create a StringBuilder that expects to hold 50 characters.
// Initialize the StringBuilder with "ABC".
StringBuilder sb = new StringBuilder("ABC", 50);
// Append three characters (D, E, and F) to the end of the StringBuilder.
sb.Append(new char[] { 'D', 'E', 'F' });
// Append a format string to the end of the StringBuilder.
sb.AppendFormat("GHI{0}{1}", 'J', 'k');
// Display the number of characters in the StringBuilder and its string.
Console.WriteLine("{0} chars: {1}", sb.Length, sb.ToString());
// Insert a string at the beginning of the StringBuilder.
sb.Insert(0, "Alphabet: ");
// Replace all lowercase k's with uppercase K's.
sb.Replace('k', 'K');
// Display the number of characters in the StringBuilder and its string.
Console.WriteLine("{0} chars: {1}", sb.Length, sb.ToString());
}
}
// This code produces the following output.
//
// 11 chars: ABCDEFGHIJk
// 21 chars: Alphabet: ABCDEFGHIJK

Make your Jenkins as code and gain speed
Why having our Jenkins coded?
One key benefit from having infrastructure and os level coded is the safety it gives to the software administrators. Think with me: what happens if your Jenkins stops working suddenly? What if something happens and nobody can log into it anymore? If these questions make you chill, let’s code our Jenkins!
What we will cover
• Packer tool for creating your SO image with your Jenkins ready to use
• Ansible for installing everything you need on your SO image (Jenkins, Kubectl, Terraform, etc).
• JCasC (Jenkins Configuration as Code) to configure your Jenkins after it is installed.
• You can also find some useful content for the Terraform part here and here.
1. How to run it
Running locally with Vagrant to test your configuration
The Vagrantfile is used for local tests only, and it is a pre-step before creating the image on your cloud with Packer
Vagrant commands:
1. Have (1) Vagrant installed (sudo apt install vagrant) and (2) Oracle’s VirtualBox
2. How to run: navigate to the root of this repo and run sudo vagrant up. After everything is complete, it will create a Jenkins accessible from your host machine at localhost:5555 and localhost:6666. This will create a virtual machine and will install everything listed on the Vagrantfile
3. How to SSH into the created machine: run sudo vagrant ssh
4. How to destroy the VM: run sudo vagrant destroy
Using packer to build your AMI or Az VM Image
Packer is a tool to create an OS image (VM on Azure OR AMI on AWS)
1. Once you have your AMI or Az VM Image created, go for your cloud console and create a new machine pointing to the newly created image.
2. Let’s configure our Jenkins as Code!
I’m listing here a few key configurations among the several you will find in each of these Ansible playbooks:
1. Liquibase version: on ansible_config/roles/ansible-role-liquibase/defaults/main.yml
2. Docker edition and version
3. Terraform version
4. Kubectl packages (adding kubedm or minikube as an example) on ansible_config/roles/ansible-role-kubectl/tasks/main.yml
5. Jenkins configs (I will comment further)
6. HAProxy for handling TLS (https) (will comment further)
3. Configuring your Jenkins
Jenkins pipelines and credentials files
This Jenkins is configured automatically using the Jenkins plugin configuration as code. All the configuration is listed on file jenkins.yaml in this root. On that file, you can add your pipelines and credentials for those pipelines to consume. Full documentation and possibilities can be found here: https://www.jenkins.io/projects/jcasc/
1. With this, we create a folder
2. Item 3 creates one pipeline job as example fetching it from a private GitLab repo that uses the credentials defined in item 1
Jenkins configuration
The plugins that this Jenkins will have installed can be found at: ansible_config/roles/ansible-role-jenkins/defaults/main.yml. If you need to get your current installed plugins, you can find how-to here: https://stackoverflow.com/questions/9815273/how-to-get-a-list-of-installed-jenkins-plugins-with-name-and-version-pair
1. The plugins list you want to have installed on your Jenkins
1. Another configuration you will change when activating TLS (https)
Jenkins’ configuration-as-code plug-in:
For JCasC to work properly, the file jenkins.yml in the project root must be added to Jenkins’ home (default /var/lib/jenkins/). This example has the keys to be used on pipelines and the pipelines as well. There are a few more options on JCasC docs.
Activating TLS (https) and Google SSO
1. As shown on step “Jenkins Configuration”‘s images: Go for ansible_config/roles/ansible-role-jenkins/defaults/main.yml. Uncomment line 15 and change it to your final URL. Comment line 16
2. Go for ansible_config/roles/ansible-role-haproxy/templates/haproxy.cfg. Change line 33 to use your final organization’s URL
3. Rebuild your image with Packer (IMPORTANT! Your new image won’t work locally because you changed Jenkins configuration)
4. Go for your cloud and deploy a new instance using your just created image
1. Move the generated file to your running instance’s folder /home/ubuntu/jenkins/
2. Restart HAProxy with sudo service haproxy restart
3.2 — Google SSO:
1. Log in to Jenkins using regular admin credentials. Go to “Manage Jenkins” > “Global Security”. Under “Authentication” select “Login with Google” and fill in like below:
• Client secret = client_secret
• Google Apps Domain = mycompany.com

Signal jammers are used for safety
For cell phone security reasons, communications experts through a thorough study of the device using electromagnetic technology have finally found an effective way to block the signal and prevent leaks, the signal jammers successfully developed . The benefits of using signal jammer are immense. In many countries it is widely used for security purposes. Jammers are the perfect example for the advancement of contemporary digital communication expertise and electronic expertise. It is also important as a new digital integration technology. Modulation mode and wireless control are the main reason for its increasing popularity.
Signal blockers are even used in universities, schools, government agencies and prisons. Blocking conversation at these places certainly cannot become a distraction. On the contract, defendants and students cannot cheat by contacting others or strangers. So the benefits of using portable cellular wave jammer are immense. It has become a mandatory addition in high security areas such as detention centers and prisons. It prevents illegal communication between visitors and detainees. Nowadays, it is even used in places like libraries and cinemas. As a result, having a jammer can help maintain a calm atmosphere, prevent cheating and increase security. Keep in mind that signal jammers are not designed to harm people or the general public. They give calm and peace to people.

Table Editor
Use the table editor to design primary and auxiliary tables. It is displayed when you select a table in App Explorer, or when you double-click a table in the list that is displayed when you select the Tables heading in App Explorer. To hide columns in the table editor or show additional columns, right-click the table header row, select Columns, and then select or clear check boxes for the columns in the menu.
Use the tabs in the Property Editor to view and modify the various aspects of the selected table.
Palette
A palette of field types and system fields is displayed to the right of the table editor. Add fields to the table by dragging them from the Table Palette to the table editor. Each of the system fields (Active/Inactive, Description, and so on) can be used only once in a table. The other (custom) field types can be used as often as needed.
Tip: You can also add a field by right-clicking the table editor, selecting Add New, and selecting the field type.
Delete a field by right-clicking it in the table editor and selecting Delete or Cut. When you delete or cut a system field type, it is returned to the list to make it available for use. Cutting a field also copies it to the Windows Clipboard, so you can paste it into the same or other tables as needed.
Note: You cannot copy a system field, or delete a required system field (such as the Title field in an auxiliary table). The System column (if displayed in the table editor) indicates whether the field is a system field.

Basic JavaScript interview questions for early career devs (0 to 2 years of experience)
In your technical interview, junior-level JS developers should be prepared to demonstrate a basic understanding of JavaScript fundamentals. This includes proficiency in JavaScript syntax, such as variable declarations, function definitions, and control structures. You should also be comfortable with debugging basics, such as using the browser console for error tracking and code testing. You’ll want to have a good grasp of JavaScript data types, such as strings, numbers, and objects,and be able to solve simple algorithms efficiently. Below are a few examples of the types of questions you can expect to be asked.
Learning tip: Practice core JavaScript skills in a realistic cloud IDE before your next interview for assessment—Mastering Algorithms and Data Structures in JavaScript in CodeSignal Learn helps you do just that.
Variables and types
Question: Write a JavaScript function checkDataTypes that takes three parameters and returns an array containing the data type of each parameter.
Sample solution:
function checkDataTypes(param1, param2, param3) {
return [typeof param1, typeof param2, typeof param3];
}
console.log(checkDataTypes(42, "hello", true)); // ["number", "string", "boolean"]
console.log(checkDataTypes(null, undefined, {})); // ["object", "undefined", "object"]
console.log(checkDataTypes([], function() {}, 3.14)); // ["object", "function", "number"]
Explanation of solution: The checkDataTypes function takes three parameters and uses the typeof operator to determine the data type of each parameter. It then returns an array containing the results. The typeof operator is a basic JavaScript feature that returns a string indicating the type of the operand.
Question: Write a JavaScript function scopeTest that demonstrates the difference between var, let, and const within different scopes (global, function, and block scope). The function should return an object with the values of the variables declared in different scopes.
Sample solution:
function scopeTest() {
var globalVar = "global var";
let globalLet = "global let";
const globalConst = "global const";
function localScope() {
var localVar = "local var";
let localLet = "local let";
const localConst = "local const";
if (true) {
var blockVar = "block var";
let blockLet = "block let";
const blockConst = "block const";
}
return {
localVar: localVar,
localLet: localLet,
localConst: localConst,
blockVar: blockVar,
blockLet: typeof blockLet !== "undefined" ? blockLet : "blockLet is not defined",
blockConst: typeof blockConst !== "undefined" ? blockConst : "blockConst is not defined"
};
}
return {
globalVar: globalVar,
globalLet: globalLet,
globalConst: globalConst,
localScope: localScope()
};
}
console.log(scopeTest());
Explanation of solution: In this solution, the function scopeTest demonstrates variable declarations using var, let, and const at the global scope. Inside the nested function localScope, it declares variables using the same keywords within both function and block scopes. The var declaration is function-scoped and accessible throughout the localScope function, including within the block. The let and const declarations are block-scoped, so they are only accessible within the block where they are defined. The solution returns an object containing the values of the variables to illustrate the differences in scope.
Operators
Question: Write a JavaScript function compareSums that takes four numbers as input, adds the first two numbers together, and then compares the sum to the sum of the second two numbers. The function should return true if the first sum is greater than the second sum, and false otherwise.
Sample solution:
function compareSums(a, b, c, d) {
let sum1 = a + b;
let sum2 = c + d;
return sum1 > sum2;
}
console.log(compareSums(5, 3, 2, 4)); // true
console.log(compareSums(1, 2, 3, 4)); // false
console.log(compareSums(10, 15, 20, 5)); // false
Explanation of solution: The compareSums function takes four parameters and calculates the sum of the first two (a and b) and the sum of the second two (c and d). It then uses the > comparison operator to check if the first sum is greater than the second sum and returns the result.
Question: Write a JavaScript function logicalCheck that takes three boolean values as input. The function should return true if at least two of the three values are true, and false otherwise.
Sample solution:
function logicalCheck(a, b, c) {
let count = 0;
if (a) count += 1;
if (b) count += 1;
if (c) count += 1;
return count >= 2;
}
console.log(logicalCheck(true, true, false)); // true
console.log(logicalCheck(false, true, false)); // false
console.log(logicalCheck(true, true, true)); // true
Explanation of solution: The logicalCheck function takes three boolean parameters and uses logical operators to determine how many of the values are true. It initializes a count variable and increments it for each true value. The function then checks if the count is greater than or equal to 2 and returns the result.
Control structures
Question: Write a JavaScript function findFirstEven that takes an array of numbers as input and returns the first even number found in the array. If there are no even numbers, return null.
Sample solution:
function findFirstEven(numbers) {
for (let i = 0; i < numbers.length; i++) {
if (numbers[i] % 2 === 0) {
return numbers[i];
}
}
return null;
}
console.log(findFirstEven([1, 3, 7, 8, 5])); // 8
console.log(findFirstEven([1, 3, 7, 5])); // null
console.log(findFirstEven([2, 4, 6])); // 2
Explanation of solution: The findFirstEven function iterates through the input array using a for loop. Within the loop, it uses an if statement to check if the current number is even (i.e., divisible by 2 with no remainder). If an even number is found, it is returned immediately. If the loop completes without finding an even number, the function returns null.
Question: Write a JavaScript function getDayName that takes a number between 1 and 7 as input and returns the corresponding day of the week (1 for Monday, 7 for Sunday). If the input is not a valid number, the function should throw an error.
Sample solution:
function getDayName(dayNumber) {
try {
switch (dayNumber) {
case 1:
return "Monday";
case 2:
return "Tuesday";
case 3:
return "Wednesday";
case 4:
return "Thursday";
case 5:
return "Friday";
case 6:
return "Saturday";
case 7:
return "Sunday";
default:
throw new Error("Invalid day number");
}
} catch (error) {
return error.message;
}
}
console.log(getDayName(1)); // "Monday"
console.log(getDayName(7)); // "Sunday"
console.log(getDayName(0)); // "Invalid day number"
Explanation of solution: The getDayName function uses a switch statement to match the input number (dayNumber) to the corresponding day of the week. If the input is not a number between 1 and 7, the default case is executed, which throws an error with the message “Invalid day number”. The try-catch block is used to handle this error, catching it and returning the error message.
Intermediate JavaScript interview questions (2 to 5 years of experience)
As a mid-level JavaScript developer with 2-5 years of experience, you should expect technical interview questions that dive deeper into your understanding of more advanced JS concepts. Be prepared to tackle questions on asynchronous programming—like handling promises, async/await syntax, and managing callbacks. You’ll want to be able to show you have a strong grasp of ES6 features, like arrow functions, destructuring, and modules, too. You should be able to discuss and implement effective error handling strategies, both synchronously and asynchronously. Familiarity with Web APIs, including the Fetch API and DOM manipulation, will likely be tested. Lastly, you’ll likely be expected to have a solid understanding of framework basics, whether it’s React, Angular, or Vue.js, which are integral to modern JavaScript development.

Functions and execution contexts
Question: Write a JavaScript function createCounter that returns an object with two methods: increment and getValue. The increment method should increase a private counter variable by 1, and the getValue method should return the current value of the counter. Demonstrate the usage of this function with both function declarations and function expressions.
Sample solution:
// Using function declaration
function createCounter() {
let counter = 0;
return {
increment: function() {
counter += 1;
},
getValue: function() {
return counter;
}
};
}
const counter1 = createCounter();
counter1.increment();
counter1.increment();
console.log(counter1.getValue()); // 2
// Using function expression
const createCounterExpr = function() {
let counter = 0;
return {
increment: function() {
counter += 1;
},
getValue: function() {
return counter;
}
};
};
const counter2 = createCounterExpr();
counter2.increment();
console.log(counter2.getValue()); // 1
Explanation of solution: The createCounter function demonstrates closures by encapsulating a private counter variable within the returned object. The increment method increases the counter, and the getValue method returns the current counter value. The function is implemented twice: once using a function declaration and once using a function expression.
Question: Write a JavaScript function createPerson that takes a name as an argument and returns an object with a method greet. The greet method should return a greeting message including the person’s name. Use an arrow function for the greet method to illustrate the this binding behavior of arrow functions.
Sample solution:
function createPerson(name) {
return {
name: name,
greet: () => `Hello, my name is ${name}`
};
}
const person1 = createPerson("Alice");
console.log(person1.greet()); // "Hello, my name is Alice"
const person2 = createPerson("Bob");
console.log(person2.greet()); // "Hello, my name is Bob"
Explanation of solution: The createPerson function returns an object with a greet method. This method is defined using an arrow function, which captures the this value from the surrounding context (the createPerson function). This ensures that the name property is correctly referenced within the greet method.
DOM manipulation and events
Question: Write a JavaScript function highlightElements that selects all <p> elements within a given container and adds a click event listener to each. When a paragraph is clicked, its background color should change to yellow. Demonstrate how this function works when passed an element ID as the container.
Sample solution:
function highlightElements(containerId) {
const container = document.getElementById(containerId);
const paragraphs = container.getElementsByTagName('p');
for (let i = 0; i < paragraphs.length; i++) {
paragraphs[i].addEventListener('click', function() {
this.style.backgroundColor = 'yellow';
});
}
}
// HTML structure for demonstration
/*
<div id="content">
<p>Paragraph 1</p>
<p>Paragraph 2</p>
<p>Paragraph 3</p>
</div>
*/
highlightElements('content');
Explanation of solution: The highlightElements function first selects the container element by its ID using getElementById. It then selects all <p> elements within the container using getElementsByTagName. A for loop is used to iterate over the paragraphs, adding a click event listener to each. The event listener changes the background color of the clicked paragraph to yellow.
Question: Write a JavaScript function addListItem that dynamically creates a new list item (<li>) with specified text and appends it to an unordered list (<ul>) with a given ID. Implement event delegation so that clicking any list item displays an alert with its text content.
Sample solution:
function addListItem(ulId, text) {
const ul = document.getElementById(ulId);
const li = document.createElement('li');
li.textContent = text;
ul.appendChild(li);
}
function setupEventDelegation(ulId) {
const ul = document.getElementById(ulId);
ul.addEventListener('click', function(event) {
if (event.target && event.target.nodeName === 'LI') {
alert(event.target.textContent);
}
});
}
// HTML structure for demonstration
/*
<ul id="myList">
<li>content</li>
</ul>
*/
addListItem('myList', 'Item 1');
addListItem('myList', 'Item 2');
setupEventDelegation('myList');
Explanation of solution: The addListItem function creates a new <li> element with the specified text and appends it to the <ul> element with the given ID. The setupEventDelegation function sets up event delegation by adding a click event listener to the <ul> element. The event listener checks if the clicked target is an <li> element and, if so, displays an alert with the text content of the clicked list item.
Advanced JavaScript interview questions (5 years experience or more)
Question: Write a JavaScript function debounce that takes a function func and a delay wait as arguments, and returns a debounced version of func. The debounced function should delay the execution of func until after wait milliseconds have elapsed since the last time the debounced function was invoked. Demonstrate how this function can be used to optimize performance by limiting the number of times a search input triggers an API call.
Sample solution:
function debounce(func, wait) {
let timeout;
return function(...args) {
clearTimeout(timeout);
timeout = setTimeout(() => func.apply(this, args), wait);
};
}
// Example usage
function searchApi(query) {
console.log(`API call with query: ${query}`);
}
const debouncedSearch = debounce(searchApi, 300);
// HTML structure for demonstration
/*
<input type="text" id="searchInput" placeholder="Search...">
*/
document.getElementById('searchInput').addEventListener('input', function(event) {
debouncedSearch(event.target.value);
});
Explanation of solution: The debounce function creates a closure that maintains a timeout variable. When the returned function is invoked, it clears any existing timeout and sets a new one to call func after wait milliseconds. This ensures that func is called only once after a specified delay, even if the debounced function is called multiple times within that period. In the example usage, the debounced searchApi function is attached to an input field’s input event, optimizing performance by limiting the number of API calls made during rapid typing.
Question: Write a JavaScript function sanitizeInput that takes a string input and returns a sanitized version of the string to prevent Cross-Site Scripting (XSS) attacks. Then, demonstrate how to implement a scalable architecture to handle form submissions securely on both client-side and server-side.
Sample solution:
function sanitizeInput(input) {
const element = document.createElement('div');
element.textContent = input;
return element.innerHTML;
}
// Example usage on client-side
document.getElementById('submitButton').addEventListener('click', function() {
const userInput = document.getElementById('userInput').value;
const sanitizedInput = sanitizeInput(userInput);
console.log(`Sanitized Input: ${sanitizedInput}`);
// Assume sendToServer is a function that sends data to the server
sendToServer(sanitizedInput);
});
// Server-side (Node.js/Express example)
const express = require('express');
const app = express();
const bodyParser = require('body-parser');
const xssFilters = require('xss-filters');
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
app.post('/submit', (req, res) => {
const userInput = req.body.userInput;
const sanitizedInput = xssFilters.inHTMLData(userInput);
console.log(`Sanitized Input on Server: ${sanitizedInput}`);
res.send(`Received sanitized input: ${sanitizedInput}`);
});
app.listen(3000, () => {
console.log('Server running on port 3000');
});
Explanation of solution: The sanitizeInput function creates a div element, sets its textContent to the input string, and then retrieves the innerHTML, effectively escaping any potentially malicious code. On the client-side, this function is used to sanitize user input before sending it to the server. On the server-side, an Express application is set up to receive form submissions. The xss-filters library is used to sanitize input data, providing an additional layer of security.
JavaScript interview questions for senior developers (10+ years of experience)
Question: How would you architect a large-scale, cross-platform application using JavaScript to ensure maintainability, scalability, and high performance? Discuss the key considerations and technologies you would use.
Sample answer:
To architect a large-scale, cross-platform application using JavaScript, I would consider the following key aspects:
• Frontend framework: Utilize a modern frontend framework like React or Angular for building the user interface. These frameworks support component-based architecture, making it easier to maintain and scale the application.
• Backend framework: Use Node.js for the backend to leverage JavaScript’s full-stack capabilities. Frameworks like Express or NestJS can provide a robust foundation for developing scalable server-side applications.
• Cross-platform development: For mobile and desktop applications, consider using frameworks like React Native or Electron. React Native allows you to write code once and deploy it on both iOS and Android, while Electron can be used for cross-platform desktop applications.
• State management: Implement a state management library such as Redux or MobX to manage the application’s state efficiently, ensuring predictable state changes and improving maintainability.
• Microservices architecture: Adopt a microservices architecture for the backend to ensure scalability and flexibility. Each microservice can be developed, deployed, and scaled independently, reducing the risk of bottlenecks.
• API design: Use RESTful APIs or GraphQL to facilitate communication between the frontend and backend. GraphQL can be particularly beneficial for complex queries and reducing the number of API calls.
• Performance optimization: Employ techniques like lazy loading, code splitting, and server-side rendering (SSR) to optimize performance. Tools like Webpack can help with bundling and optimizing assets.
• Testing: Implement comprehensive testing strategies, including unit tests, integration tests, and end-to-end tests, using tools like Jest, Mocha, and Cypress.
• Continuous Integration and Deployment (CI/CD): Set up CI/CD pipelines to automate testing and deployment, ensuring quick and reliable releases. Tools like Jenkins, Travis CI, and GitHub Actions can be useful.
• Security: Implement security best practices, such as input validation, authentication, authorization, and secure data storage. Use libraries like Helmet.js for securing HTTP headers and OAuth for authentication.
Question: What strategies would you employ to optimize the performance of a legacy JavaScript application while managing technical debt and ensuring future scalability? Discuss your approach and the tools you would use.
Sample answer:
To optimize a legacy JavaScript application, I would start with a thorough code audit to identify bottlenecks and areas with high technical debt, refactoring for better readability and maintainability. Using performance profiling tools like Chrome DevTools and Lighthouse, I would analyze metrics such as load time and rendering performance. Optimizing asset delivery through minification, compression, and image optimization, leveraging tools like Webpack, would be my next step. Implementing lazy loading and code splitting would help reduce initial load times, and employing caching strategies, such as browser and server-side caching along with CDNs, would enhance performance.
Database optimization is crucial, so I would ensure queries and indexing are efficient, considering ORM tools for streamlined interactions. I would use asynchronous operations, utilizing Promises and async/await, to prevent blocking of the main thread and improve performance. Establishing robust monitoring and logging with tools like New Relic and Sentry would help track performance metrics and identify real-time issues.
To manage technical debt, I would prioritize critical issues and create a gradual refactoring plan. Lastly, to ensure scalability, I would employ microservices, containerization (Docker), and orchestration tools like Kubernetes, enabling efficient handling of increased load and traffic. This approach balances immediate performance gains with long-term maintainability and scalability.
JavaScript interview questions by focus area
JavaScript front-end interview questions
Question: Write a React component Counter that includes a button and a display of the current count. The count should start at 0 and increment by 1 each time the button is clicked. Use React’s useState hook for state management.
Sample solution:
import React, { useState } from 'react';
function Counter() {
const [count, setCount] = useState(0);
return (
<div>
<p>Current Count: {count}</p>
<button onClick={() => setCount(count + 1)}>Increment</button>
</div>
);
}
export default Counter;
Explanation of solution: The Counter component uses React’s useState hook to manage the count state. The useState hook initializes count to 0 and provides a setCount function to update it. When the button is clicked, the onClick handler increments the count state by 1 using setCount.
Question: Create a simple React application with two routes: Home and About. Use React Router for client-side routing and ensure that both pages are accessible, including appropriate aria attributes.
Sample solution:
import React from 'react';
import { BrowserRouter as Router, Route, Link, Switch } from 'react-router-dom';
function Home() {
return (
<div>
<h1>Home Page</h1>
<p>Welcome to the home page!</p>
</div>
);
}
function About() {
return (
<div>
<h1>About Page</h1>
<p>Learn more about us on this page.</p>
</div>
);
}
function App() {
return (
<Router>
<nav>
<ul>
<li>
<Link to="/" aria-label="Home">Home</Link>
</li>
<li>
<Link to="/about" aria-label="About">About</Link>
</li>
</ul>
</nav>
<Switch>
<Route exact path="/" component={Home} />
<Route path="/about" component={About} />
</Switch>
</Router>
);
}
export default App;
Explanation of solution: The App component sets up client-side routing using React Router. The Router component wraps the entire application, and Switch handles the routing logic. Route components define the paths for Home and About pages, each rendering the respective component. The nav element contains Link components for navigation, with aria-label attributes for accessibility.
JavaScript interview questions for automation testing
Question: Write a simple unit test for a JavaScript function add(a, b) that returns the sum of two numbers. Use the Jest testing framework.
Sample solution:
// add.js
function add(a, b) {
return a + b;
}
module.exports = add;
// add.test.js
const add = require('./add');
test('adds 1 + 2 to equal 3', () => {
expect(add(1, 2)).toBe(3);
});
test('adds -1 + -1 to equal -2', () => {
expect(add(-1, -1)).toBe(-2);
});
Explanation of solution: The add function is a simple utility that returns the sum of two numbers. The unit tests are written using the Jest testing framework. The test function defines individual test cases, where the expect function is used to assert that the result of add(a, b) matches the expected value.
Question: Write a simple end-to-end test using Selenium WebDriver for a web page with a login form. The form includes two inputs (username and password) and a submit button. The test should check that after entering the credentials and submitting the form, the user is redirected to a dashboard page.
Sample solution:
// login.test.js
const { Builder, By, until } = require('selenium-webdriver');
const assert = require('assert');
(async function loginTest() {
let driver = await new Builder().forBrowser('chrome').build();
try {
await driver.get('http://localhost:3000/login');
await driver.findElement(By.name('username')).sendKeys('testuser');
await driver.findElement(By.name('password')).sendKeys('password123');
await driver.findElement(By.css('button[type="submit"]')).click();
await driver.wait(until.urlIs('http://localhost:3000/dashboard'), 5000);
let currentUrl = await driver.getCurrentUrl();
assert.strictEqual(currentUrl, 'http://localhost:3000/dashboard');
} finally {
await driver.quit();
}
})();
Explanation of solution: This solution uses Selenium WebDriver for browser automation. The test script navigates to the login page, enters the username and password, and submits the form. It then waits until the URL changes to the dashboard page and asserts that the current URL is as expected.
JavaScript algorithm interview questions
Question: Write a JavaScript function mergeSort that sorts an array of numbers using the merge sort algorithm. Analyze the time and space complexity of your implementation.
Sample solution:
function mergeSort(arr) {
if (arr.length <= 1) {
return arr;
}
const mid = Math.floor(arr.length / 2);
const left = mergeSort(arr.slice(0, mid));
const right = mergeSort(arr.slice(mid));
return merge(left, right);
}
function merge(left, right) {
let result = [];
let leftIndex = 0;
let rightIndex = 0;
while (leftIndex < left.length && rightIndex < right.length) {
if (left[leftIndex] < right[rightIndex]) {
result.push(left[leftIndex]);
leftIndex++;
} else {
result.push(right[rightIndex]);
rightIndex++;
}
}
return result.concat(left.slice(leftIndex)).concat(right.slice(rightIndex));
}
// Example usage
const array = [38, 27, 43, 3, 9, 82, 10];
console.log(mergeSort(array)); // [3, 9, 10, 27, 38, 43, 82]
Explanation of solution: The mergeSort function recursively divides the array into halves until it has arrays of length 1 or 0. The merge function then combines these smaller arrays back together in sorted order. The time complexity of merge sort is O(n log n) because the array is split in half log n times, and merging the arrays takes linear time. The space complexity is O(n) due to the additional arrays created during the merge process.
Question: Write a JavaScript function binaryTreePaths that takes the root of a binary tree and returns all root-to-leaf paths in the tree as an array of strings. Use recursion to solve this problem.
Sample solution:
function binaryTreePaths(root) {
const paths = [];
function dfs(node, path) {
if (!node) return;
path += node.val;
if (!node.left && !node.right) {
paths.push(path);
} else {
path += '->';
dfs(node.left, path);
dfs(node.right, path);
}
}
dfs(root, '');
return paths;
}
// Example usage
const tree = {
val: 1,
left: {
val: 2,
left: null,
right: {
val: 5,
left: null,
right: null
}
},
right: {
val: 3,
left: null,
right: null
}
};
console.log(binaryTreePaths(tree)); // ["1->2->5", "1->3"]
Explanation of solution: The binaryTreePaths function uses a depth-first search (DFS) approach to traverse the binary tree. The dfs helper function is called recursively, building the path as it traverses the tree. When a leaf node is reached, the current path is added to the paths array.
Tricky JavaScript interview questions
Question: Write a JavaScript function createExpensiveResource that simulates the creation of an expensive resource (e.g., a large array). Use closures to manage access to this resource and implement a method to release it properly to prevent memory leaks.
Sample solution:
function createExpensiveResource() {
let resource = new Array(1000000).fill('some data');
function accessResource() {
if (!resource) {
console.log("Resource has been released.");
return;
}
return resource;
}
function releaseResource() {
resource = null;
console.log("Resource has been released.");
}
return {
access: accessResource,
release: releaseResource
};
}
// Example usage
const resourceManager = createExpensiveResource();
console.log(resourceManager.access()); // Access the resource
resourceManager.release(); // Release the resource
console.log(resourceManager.access()); // Try to access the released resource
Explanation of solution: The createExpensiveResource function creates a large array and uses closures to provide controlled access to it. The accessResource function allows access to the resource, while the releaseResource function sets the resource to null, freeing up memory. This solution demonstrates closure applications and how to prevent memory leaks by properly releasing resources.
Why it’s tricky: This question is tricky because it tests your understanding of closures and how they can inadvertently cause memory leaks if resources are not properly managed. It requires knowledge of both resource management and the use of closures to control access to variables.
Question: Explain the output of the following JavaScript code and why it behaves that way. Discuss the concepts of the event loop and the concurrency model that affect the output.
console.log('Start');
setTimeout(() => {
console.log('Timeout');
}, 0);
Promise.resolve().then(() => {
console.log('Promise');
});
console.log('End');
Sample output:
Start
End
Promise
Timeout
Sample answer:
The output of the code is determined by JavaScript’s event loop and concurrency model. When the script runs:
1. console.log('Start') is executed first, printing “Start”.
2. setTimeout is called with a delay of 0 milliseconds, which schedules the callback to be executed in the next iteration of the event loop.
3. Promise.resolve().then is called, which schedules the callback to be executed after the current execution context finishes, before the next event loop iteration.
4. console.log('End') is executed next, printing “End”.
5. After the current execution context finishes, the microtask queue (containing the resolved promise callback) is processed first.
6. The macrotask queue (containing the setTimeout callback) is then processed. Thus, “Promise” is printed before “Timeout”.
Why it’s tricky: This question is tricky because it explores the intricacies of JavaScript’s event loop and concurrency model. Understanding the order of execution between synchronous code, microtasks (promises), and macrotasks (setTimeout) requires you to have a deep understanding of how JavaScript handles asynchronous operations and task scheduling.
Most common JavaScript practice questions (if you have limited time)
In JavaScript interviews, you will often face a variety of question types designed to assess your technical skills and problem-solving abilities. Common algorithm problems, which require you to demonstrate your understanding of data structures and algorithmic efficiency, are a staple of JavaScript interviews. You’ll likely also be asked about JavaScript quirks, such as type coercion and scope behavior, to gauge your depth of knowledge about the language. Coding challenges are another popular format, often presented in real-time coding environments, where you must solve complex problems using key JavaScript methods. Interview cheat sheets can be valuable resources for quick reference on syntax and common functions.
Question: Write a JavaScript function findDuplicates that takes an array of numbers and returns an array of duplicate numbers. Ensure that each duplicate number appears only once in the output array.
Sample solution:
function findDuplicates(arr) {
const seen = new Set();
const duplicates = new Set();
for (let num of arr) {
if (seen.has(num)) {
duplicates.add(num);
} else {
seen.add(num);
}
}
return Array.from(duplicates);
}
// Example usage
console.log(findDuplicates([1, 2, 3, 1, 2, 4])); // [1, 2]
console.log(findDuplicates([5, 5, 5, 5, 5])); // [5]
console.log(findDuplicates([1, 2, 3, 4, 5])); // []
Explanation of solution: The findDuplicates function uses two sets: seen to track numbers that have already been encountered, and duplicates to track numbers that appear more than once. The function iterates through the array, adding numbers to seen and, if a number is already in seen, adding it to duplicates. The function finally returns an array created from the duplicates set.
Question: Explain the difference between null and undefined in JavaScript. Provide examples to illustrate the key differences.
Sample solution:
null and undefined are both JavaScript primitives representing the absence of a value, but they have different meanings and uses. undefined indicates that a variable has been declared but has not yet been assigned a value. null is an assignment value that represents no value or an empty value. For example:
let uninitializedVar; // undefined
let emptyVar = null; // null
console.log(typeof uninitializedVar); // "undefined"
console.log(typeof emptyVar); // "object"
console.log(uninitializedVar == null); // true
console.log(uninitializedVar === null); // false
console.log(emptyVar == undefined); // true
console.log(emptyVar === undefined); // false
Explanation of solution: In this example, uninitializedVar is declared but not assigned a value, so it is undefined. emptyVar is explicitly assigned the value null. The typeof operator shows that undefined is its own type, while null is considered an object due to a historical bug in JavaScript. The comparison examples demonstrate that == treats both null and undefined as equal, while === does not.
Question: Write a JavaScript function capitalizeWords that takes a string and returns a new string with the first letter of each word capitalized.
Sample solution:
function capitalizeWords(str) {
return str.split(' ').map(word => word.charAt(0).toUpperCase() + word.slice(1)).join(' ');
}
// Example usage
console.log(capitalizeWords('hello world')); // "Hello World"
console.log(capitalizeWords('javascript is fun')); // "Javascript Is Fun"
console.log(capitalizeWords('capitalize each word')); // "Capitalize Each Word"
Explanation of solution: The capitalizeWords function splits the input string into an array of words, capitalizes the first letter of each word, and then joins the words back into a single string. The split, map, charAt, toUpperCase, and slice methods are used to transform the string.

Vb validating
Basically, you want to take two controls on the page: a Radio Button List for the country choice, and a Text Box for the ZIP code. Is Valid to determine whether or not the page is filled in completely. Josef Finsel is a software consultant with a global consulting firm and specializes in . NET, a programming language that works the way programmers have always suspected. When you mix two controls together for validation, it gets a little trickier. Is Valid = True End If The final point of note is that this doesn't keep you from checking Page. The final code, which is available for download, also contains a Required Field Validator for the Country Radio Button List, and the end of the Button Press event actually checks Page. The sample code referenced in this article is available for download. NET, and SQL Server-related articles, and when he isn't hanging around the aspnetpro forums, you can find him working on the syntax for Fizz Bin.It's nothing too exciting - a Radio Button List, a Text Box, and a button to submit it all. This is what the page looks like before the Custom Validator control is added. Text = "Valid data" End If As long as you're doing this, you might as well determine whether the ZIP code is formatted correctly: If (rb Country. The first thing you want to add is a Custom Validator control. Text, " "c) = True Then result = result & "- First Name field has spaces" & vb New Line End If If In Str(txt First Name. Text)) = True Then result = result & "- First Name field has numbers" & vb New Line End If 'last name field validation If txt Last Name. Length = 0 Then result = result & "- Last Name field is empty" & vb New Line End If If In Str(txt Last Name. Text, " "c) = True Then result = result & "- Last Name field has spaces" & vb New Line End If If In Str(txt Last Name. Text)) = True Then result = result & "- Last Name field has numbers" & vb New Line End If 'major validation If txt Major. Length = 0 Then result = result & "- Major field is empty" & vb New Line End If If In Str(txt Major. Click Dim error Str As String = "" error Str = Validate Fields() If error Str = "" Then 'place all the student field data into the array of elements ary Data(0) = txt First Name. add If statements for the fields you want to validate Private Function Is Quick Admission Valid() As String 'return string value containing the missing pieces if it is invalid.

Cancel Event Args) Dim dec As Decimal If Not Decimal. I'll admit, I'm not very well versed in them as I've not taken the time to mess with them but I do know that you can validate these types of situations with them and that there are a lot of knowledgeable people that frequent this forum that can help you with them. Here is what I received when entering your data You could use this same thing for anything where you're testing length of the string. Text, " "c) = True Then result = result & "- First Name field is empty or contains illegal characters" & vb New Line End If Else Msg Box("First Name is empty") End If Public Class Form4 Private Sub Text First Name_Validating(By Val sender As Object, By Val e As System. If that isn't the way you want to go you could simply use . For example 'in the click event Dim str As String = "" str = Is Valid() If str = "" Then ' Its all valid so do w/e here Else msgbox("The following fields are invalid: " & str) End If 'the Is Valid Sub. Text 'join the array elements and place the result into a string variable new Student Record = Join(ary Data, " ") 'create a link between the form and the file with streamwriter and write to the text file If System. Also for: This way you've accomplished both of those in one block. And I can't put a required control on it, because it isn't always required. A: Validator controls come in many different flavors. The problem is if there is no value in the ZIP code box, a custom validation control still considers it valid.

Wątki - wait(), notify(), notifyAll();
0
To mój pierwszy post na tym forum więc się przywitam :)))
WITAM ;)))
Post ten zamieścilem już na dwóch forach, ale zero odzewu było więc spróbuje tutaj.... :))
Mam problem, otóż dostałem zadanie do zrobienia z wątków.
Chodzi o program, który ma 3 wątki. Mają one po kolei wypisywać na ekranie 1 , 2 , 3.. Wątek jeden wypusuje 1, drugi 2 itd...
To co się dzieje w metodzie run() ma być w bloku synchronized (nic nowego chyba ;P) ogólnie program ma wyglądać tak jak napisałem...chyba...
Problem tkwi w tym, że to co ja napisałem wykonuje się tylko raz, a nie kilka...
Bardzo bym prosił o wyjaśnienie co mam źle w tym kodzie :)))
oto kod:

{

}
public void run()

{

{
while(t.n!=1)
{
try {wait();
} catch(InterruptedException exc) {}
}
System.out.println("1 ");
t.n=2;
this.notify();
}
}
}
}
class T2 extends Thread

t = z;
}

while(true)
{
while(t.n!=2)
{
try {wait();} catch(InterruptedException exc) {}
}
System.out.println("2 ");
t.n=3;
this.notify();
}
}
}}
class T3 extends Thread
{
Licznik t;
T3(Licznik z)
{
t = z;
}
public void run()
{
synchronized(this)
{
while(true)
{
while(t.n!=3)
{
try {wait();} catch(InterruptedException exc) {}
}
System.out.println("3 ");
t.n=1;
this.notifyAll();
}}
}
}
public class Zadanie

Proste.
Jeżeli synchronizujesz coś takiego:
synchronized(this){
while(true){
//...
}
}
To popatrz co się stanie. Odpalasz pierwszy wątek i w tym momencie zostaje rozpoczęta synchronizacja. Oznacza to, że do momentu aż nie zostanie zakończona operacja przeprowadzana przez ten wątek inne wątki nie będa uruchamiane. Problem polega na tym, że synchronizowaną operacją jest nieskończona pętla! Zatem operacja synchronizowana nigdy się nie zakończy i tym smaym inne wątki nigdy nie zostaną uruchomione.

Ten program po skompilowaniu wyświetla 1 , 2 , 3 więc nie są blokowane...
Chodzi o to, ze wyswietla tylko raz, oczywiscie mogę dać tam petle for(int i=0; i<3;i++) ale będzie to samo bo sprawdzałem....
Wydaje mi się, ze to jest kwestia złego rozmieszczenia wait() i notify() (ale moge się mylić...)
Poaztym jeżeli nie dam tego w pętli, to sie nie będzie powtarzało wypisywanie, bo jak sie skończy metoda run() to wtedy wątek kończy swój żywot....
Właśnie spróbowałem dac bloki synchronized() niżej, czyli zaraz po "while(true) {" i taki sam efekt....

oj koziolek koziolek
od kiedy to synchronizacja uniemozliwia ruszenie innych watkow?
tutaj problemem jest ze wolana jest metoda wait(), blokujaca watek, a pozniej dalej wolana jest notify() -problem w tym ze do tego wywolania zaden watek nie dojdzie - pamietaj ze zaden watek po wywolaniu wait() sam na sobie nie wywola notify() - to musi zrobic inny watek, a jako ze nie masz nigdy pewnosci ktory z watkow czekajacych na jakis warunek (wait()) zostanie zawiadomiony, bezpieczniej jest wywolac notifyAll()
ty natomiast nie masz na czyms wywolac tego notify(), poniewaz w run() synchronizujesz na this, a zaden inny watek nie ma referencji do pozostalych 2 watkow
dzialanie - wszystkie watki startuja, synchronizuja sie na sobie, i czekaja az ktos wywola na nich notify(), ale NIKT tego nie moze zrobic
polecam koledze zapoznac sie dokladniej z watkami i waitami notifajami itp (koziolkowi rowniez :>)
pozdrawiam
PS rogaty nie obrazaj sie, wiem ze kkazdy moze sie pomylic, tak tylko sobie zartuje ;-) peace

Nigdy nie byłem mocny z współbieżności. Sensownie wygląda to co mówisz. Ja bym dodał jeszcze, że wypadało by przerobić te trzy klasy w jedną, która będzie bardziej ogólna. I kodu mniej i jakoś łatwiej zrozumieć jak wszytko w jednym miejscu. Funkcjonalność związaną z numerowaniem można zastąpić warunkiem z resztą z dzielenia.
ide se poczytać.

Dzięki wielkie "oj koziołku" :))
Na dwóch forach dałem i nikt nie odpisał :))
Zrobiłem, śmiga, w sumie nie pomyślałem ze tym "this" tak było w przykładach, a wiadomo ze trzeba podać obiekt do którego w danym czasie ma dostęp tylko jeden wątek :))
tutaj zamieszczam poprawiony kod :))) zmienilem while(true) na "for", żeby sie nie wykonywąło w nieskończoność :))
class Licznik
{
public int n = 1;
}
class T1 extends Thread
{
Licznik t;
T1(Licznik z)
{
t = z;
}
public void run()
{
for (int i=0;i<3; i++) {
synchronized (t)
{
while(t.n!=1)
{
try {t.wait();
} catch(InterruptedException exc) {}
}
System.out.print("1, ");
t.n=2;
t.notify();
}
}
}
}
class T2 extends Thread
{
Licznik t;
T2(Licznik z)
{
t = z;
}
public void run()
{
for (int i=0;i<3; i++) {
synchronized (t)
{
while(t.n!=2)
{
try {t.wait();} catch(InterruptedException exc) {}
}
System.out.print("2, ");
t.n=3;
t.notify();
}
}
}}
class T3 extends Thread
{
Licznik t;
T3(Licznik z)
{
t = z;
}
public void run()
{
for (int i=0;i<3; i++){
synchronized(t)
{
while(t.n!=3)
{
try {t.wait();} catch(InterruptedException exc) {}
}
System.out.println("3 ");
t.n=1;
t.notifyAll();
}
} }
}
public class Zadanie
{
public static void main (String [] args)
{
Licznik licznik = new Licznik();
T3 t3 = new T3(licznik);
T1 t1 = new T1(licznik);
T2 t2 = new T2(licznik);
t1.start();
t2.start();
t3.start();
}
}
JESZCZE RAZ WIELKIE DZIĘKI :))))
Jeżeli chodzi o zebranie w jedną klasę, to zadanie wlaśnie miało posiadać trzy klasy z wątkami, wiec już nie bede kombinował :))
Jeżeli chodzi o zastosowanie reszty z dzielenia to wydaje mi sie, że warunek z dodawaniem jest mniej czasochłonny niż operacja dzielenia....

zeby sobie pocwiczyc napisalem takie cos, zawierajac wskazowki koziolka:
class Licznik {
public int n = 1;
public Licznik() {
reset();
}
public int getValue() {
return n;
}
/*synchronized*/ public void increment() {
// wydaje sie ze metoda powinna byc synchronizowana
// poniewaz 3 watki beda sie do niej dobierac
// ale to tylko w teorii - poniewaz tak mamy napisany program ze wiemy
// ze na raz tylko jeden watek moze ja wywolac bo reszta czeka na
// notify() wiec mozna synchronized wywalic
// gdybysmy takiej wiedzy nie mieli to bysmy musieli to zostawic
++n;
if (n == 4) {
// jesli 4, to przekrecamy licznik
n = 1;
}
}
public void reset() {
n = 1;
}
}
class MyThread extends Thread {
private Licznik t;
private int output;
public MyThread(Licznik z, int output) {
t = z;
this.output = output;
}
public void run() {
while (true) {
synchronized (t) {
while (t.getValue() != output) {
// jesli nie moja kolej wypisac to czekam
// robimy to w petli ze wzgledu na to ze moze to i tak nie nasza kolej
// tylko tego drugiego ;-)
try {
t.wait();
} catch (InterruptedException e) {
e.printStackTrace();
return;
}
}
// doszlismy tutaj wiec pora wypisac
// jesli to 3, to dajemy nowa linie, ladniej widac wszystko
System.out.print(output + (output == 3 ? "\n" : " "));
// zwiekszyc licznik
t.increment();
// oraz zawiadomic pozostale 2 watki ze ktorys z nich moze
// wykonac swoj kod
t.notifyAll();
}
}
}
}
public class Test {
public static void main(String[] args) {
Licznik licznik = new Licznik();
MyThread t1 = new MyThread(licznik, 1);
MyThread t2 = new MyThread(licznik, 2);
MyThread t3 = new MyThread(licznik, 3);
t1.start();
t2.start();
t3.start();
}

Jeżeli chcesz nauczyć się wielowątkowość w javie, to zapoznaj się z pakietem java.util.concurrent(od javy 5)
Są tam, np. java.util.concurrent.atomic.AtomicInteger, czyli integer na którym pewne operacje są atomowe, czy java.util.concurrent.ArrayBlockingQueue dzięki której można w banalny sposób wykonać schemat producenci-konsumenci.
Jeżeli do synchronizacji używa się tylko synchronized() i notify(), to po pewnym czasie coraz trudniej przewidzieć wszystkie przebiegi wątków.
/*synchronized*/ public void increment()
Masz rację, w tym szczególnym przypadku synchronized nie jest konieczne.

__krzysiek85, dzięki za radę :))
Moim zadaniem było właśnie wykorzystać wait(), notify() i notifyAll()...
Jeżeli będe chcial bardziej zgłębić współbieżność wtedy sięgnę po tę klasę :)))
Pozdro
Temat uważam za zamknięty :))

Mimo że temat zamknięty, to coś napiszę. U mnie twój kod nie działa. Zadziałał jak zmieniłem notify() na notifyAll().
pozdrawiam

Angular code is decoupled from the underlying runtime environment, so in theory our code could run on any type of host. In this post we will show how to use NativeScript in combination with Angular to create a native app.
We have already showed how to execute Angular on the server and in a web worker.
Now it's time to see if we can get our code to run in a native mobile environment as well.
What is NativeScript?
NativeScript is a third party framework created to map Angular code to native code running on IOS and Android devices.
Normally when we write Angular code we often target the browser, but as long as we don't reference browser specific apis, our code is not in any way locked into a browser environment. As I mentioned earlier NativeScript is just one example where we benefit from this abstraction from the runtime environment.
We have only just started looking at NativeScript, but was pleasantly surprised to see how easy it is to port Angular code to native device code. The best part is that we only have to worry about writing our Angular code. NativeScript and its tooling will take care of the conversion to native device code.
To put the theory to the test we decided to port two sample components using NativeScript. We wanted to move beyond a simple “Hello World” app, so we decided to pick components where we use both RxJs and timers.
The code and concepts port over nicely, but perhaps the biggest adjustment is getting used to mobile view terminology. In the native world we can no longer write standard html views, so we have to get used to new ui elements and layout schemes. In some ways the NativeScript layout approach reminded me a bit of Layout Managers in Java Swing.
Anyway, let's take a look at the sample components.
RxJs
The first component is a simple adder component where the user taps three numbers and the component spits out the sum of the numbers. On the surface this is a trivial component to write, but it's done using RxJs to prove that we can still benefit from Rx even in the native world.
As you can see from the code the component part is pretty familiar to anyone who's ever written an Angular application.
import {Component} from '@angular/core'; import {Subject} from 'rxjs/Subject'; @Component({ selector: 'adder', template: ` <Label text="Tap three numbers" class="title"></Label> <Button (tap)="add(number)" class="box" *ngFor="let number of numbers" [text]="number"></Button> <Label *ngIf="showSum" class="sum-box" [text]="calculation.sum"></Label> ` }) export class Adder{ numbers = [1,2,3,4,5]; sum = new Subject<number>(); calculation = {}; showSum = false; add(number){ this.sum.next(number); } ngOnInit(){ this.sum .asObservable() .do(a => this.showSum = false) .bufferCount(3) .subscribe(res => { this.calculation = {sum:res.reduce((a,b) => a + b)}; this.showSum = true; }); } }
The only exception is of course the template where we have to get used to new elements like Label and Button. We also use 'tap' instead of click. But as you can see we can still use RxJs the same way we use it on the web. Change detection is also completely transparent, so the ui will update just like it would on the web.
Timer
The second component is a simple sorting component where we sort a list, but use a timer to delay the sorting updates as the algorithm shuffles through the data. The point here is to show an example where we have to make a few minor adjustments to the code to make it work on “native”.
In my original sample we used setTimeout. SetTimeout is an example of an api specific to the browser, so to make it work we have to make a slight change. Luckily the change is trivial since all we have to do is import a timer from a NativeScript module.
As we can see from the sorting code below, updating the sorting algorithm to use the new timer is trivial.
var timer = require("timer"); export class InsertionSortService{ sort(input){ for(let j = 1; j < input.items.length; j++){ (function(j){ timer.setTimeout(() => { let key = input.items[j].val; let i = j - 1; while(i >= 0 && input.items[i].val > key){ input.items[i + 1].val = input.items[i].val; i = i - 1; } input.items[i + 1].val = key; input.setCurrent(input.items[i + 1]); },500 * j); })(j); } } }
In the component we inject the sorting service and call it to sort the provided list of integers.
import {Component, Input} from '@angular/core'; import {InsertionSortService} from './insertion-sort.service'; @Component({ selector: 'insertion-sort', templateUrl: './components/algorithms/insertion-sort.component.html', providers: [InsertionSortService] }) export class InsertionSortComponent { @Input() list:ValList; btnText = 'Sort'; constructor(private sortingService: InsertionSortService){ this.list = new ValList(); this.list.items = [ new ListItem(5), new ListItem(33), new ListItem(5), new ListItem(4), new ListItem(88), new ListItem(40), new ListItem(-88), new ListItem(6), new ListItem(1), new ListItem(58), new ListItem(30) ]; } sortList(){ this.sortingService.sort(this.list) } } class ValList{ items:Array; setCurrent(item){ this.clearAll(); item.current = true; } clearAll(){ this.items.forEach(i => i.current = false); } } class ListItem{ val:Number; current:Boolean; constructor(val){ this.val = val; this.current = false; } }
Notice in this sample we are using templateUrl instead of an inline template. Unsurprisingly the template url points to a view file where our template is defined. That said, we are not using standard html even though the extension of the template file is .html.
We won't spend too much time on the template, but notice the StackLayout which is an example of a layout scheme in NativeScript.
<StackLayout orientation="horizontal"> <Label class="small-box" *ngFor="let item of list.items" [text]="item.val"></Label> </StackLayout> <Button (tap)="sortList()" [text]="'Sort'">Tee</Button>
Resources
I am not spending a lot of time explaining how to setup a NativeScript project since the NativeScript team has already provided a lot of good examples here. I did however post my sample code on Github in case you are interested in taking a look.
Simulator
To test my code I loaded it up in the IOS simulator in a tabbed view.
Here are two screenshots of the final application:

dpkg-source argument to ignore .git subdirectory
There seems to be some confusion what's the correct way to ignore only
the .git subdirectory (and not anything else gittish, which might have
been present in the .diff.gz before).
Has anybody come up with a proper regexp for -i? Would
-I.git '-i^\.git/'
do the trick?

Admob for Flutter #
A GoogleAdmob plugin for Flutter. Currently supports interstitial ads in both iOS and Android.
Getting Started #
The plugin contains two methods for loading and showing interstitial ads. In order to use them we must first import a couple of packages:
import 'package:admob/admob.dart';
import 'package:flutter/services.dart';
[iOS DEVELOPERS NOTE: Developed for Objective C. You cannot use 'use_frameworks' in your new project's podfile]
Interstitial Ads #
Interstitial ads will display on both Android and iOS devices. In order to display our ads we need to pass Admob a few parameters. For more info on the app id and ad unit id visit http://google.com/admob.
String APP_ID = "Your APP ID";
String AD_UNIT_ID = "Your Ad_unit_id";
String DEVICE_ID = "Only necessary for testing: The device id you are testing with";
bool TESTING = A boolean declaring whether you are testing ads or live;
Async Methods #
There are two asynchronous functions that we use, one to load the ad and one to show it.
The plugin's loadInterstitial method accepts an APP_ID, AD_UNIT_ID, DEVICE_ID, and TESTING. The loadInterstitial method should be called in an init method to load an ad as the app starts. After that the ads will reload themselves whenever you close the previous one. The plugin's showInterstitial method accepts no variables, and as the name implies shows the ad you loaded with loadInterstitial. If the ad is not yet loaded the showInterstitial method will return false.
@override
initState(){
super.initState();
loadInterstitialAd();
}
loadInterstitialAd() async {
bool loadResponse;
try {
loadResponse = await Admob.loadInterstitial(APP_ID, AD_UNIT_ID, DEVICE_ID, TESTING);
} on PlatformException {
loadResponse = false;
}
setState(() {
_loadInterstitialResponse = loadResponse;
});
}
showInterstitialAd() async {
bool showResponse;
try {
showResponse = await Admob.showInterstitial;
} on PlatformException {
showResponse = false;
}
setState(() {
_showInterstitialResponse = showResponse;
});
}
Now whenever we want to show the ad we simply call it:
showInterstitialAd()
An example of how to do that:
@override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
title: new Text('Plugin example app'),
),
body: new Center(child:new Text("$_showInterstitialResponse")),
floatingActionButton: new FloatingActionButton(
onPressed: () => showInterstitialAd(),
child: new Icon(Icons.add),
),
);
}
View the example code included with the plugin in the example folder to see usage. The main.dart file included in the example folder shows an implementation of the plugin.
We currently have limited support for banner ads on the iOS platform. Banner ads work largely the same way as our interstitial do. Unlike interstitial there is no load function. Whenever we want a banner we simply call showBanner. The showBanner method accepts an extra variable over the loadInterstitial:
The important new variable is PLACEMENT. You should pass either "Top" or "Bottom" in this variable when displaying a banner ad. This declares where the ad will be shown.
String APP_ID = "Your app id";
String INTERSTITIAL_AD_UNIT_ID = "Your ad unit id";
String DEVICE_ID = "(NOT REQD): Your device ID, to display test ads on a specific device";
bool TESTING = A Boolean declaring whether ads should be live or testing;
String PLACEMENT = "Top"
We are now left needing our async functions. We have two of them, showBanner and closeBanner, they return a string that can be described as a banner state. If the ad is shown properly it returns "ShowingTop" or "ShowingBottom" depending on placement or else it returns "NotShown". A banner does not have to be closed. It is simple an option for people looking to display one temporarily:
showBannerAd() async {
var showResponse = "";
try {showResponse = await Admob.showBanner(APP_ID, INTERSTITIAL_AD_UNIT_ID, DEVICE_ID, TESTING, PLACEMENT);}
on PlatformException {showResponse = "Not Shown";}
setState(() {
_BannerState = showResponse;
});
}
closeBannerAd() async {
var showResponse = "";
try {
_BannerState = await Admob.closeBanner();
print(_BannerState);
} on PlatformException {
showResponse = "Not Closed";
}
setState(() {
_BannerState = showResponse;
});
}

Authorizing with Google for REST APIs
When you want your Android app to access Google APIs using the user's Google account over HTTP, the GoogleAuthUtil class and related APIs provide your users a secure and consistent experience for picking an account and retrieving an OAuth 2.0 token for your app.
You can then use that token in your HTTP-based communications with Google API services that are not included in the Google Play services library, such as the Blogger or Translate APIs.
To get started with GoogleAuthUtil for accessing Google's REST APIs, you must set up your Android app project with the Google Play services library. Follow the procedures in Setup Google Play Services SDK.
Register your app
Before you can publish an app that retrieves an OAuth 2.0 token for Google REST APIs, you must register your Android app with the Google Cloud Console by providing your app's package name and the SHA1 fingerprint of the keystore with which you sign your release APK.
To register your Android app with Google Cloud Console:
1. Visit Google Cloud Console.
2. If you have an existing project to which you're adding an Android app, select the project. Otherwise, click Create project at the top, enter your project name and ID, then click Create. Note: The name you provide for the project is the name that appears to users in the Google Settings app in the list of Connected apps.
3. In the left-side navigation, select APIs & auth.
4. Enable the API you'd like to use by setting the Status to ON.
5. In the left-side navigation, select Credentials.
6. Click Create new client ID or Create new key as appropriate for your app.
7. Complete the form that appears by filling in your Android app details. To get the SHA1 fingerprint for your app, run the following command in a terminal:
keytool -exportcert -alias -keystore -list -v
For example, you're using a debug-key with Eclipse, then the command looks like this:
keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore -list -v
Then the keystore password is "android".
8. Click Create.
The Credentials page then provides the available credentials such as an OAuth 2.0 client ID and an Android Key, but you don't need these to authorize your Android users. Simply registering your app with the package name and SHA1 makes the Google services accessible by your app.
To acquire the OAuth 2.0 token that will grant you access to Google APIs over HTTP, you need to first identify the user's Google account with which you'll query the servers. For this task, the Google Play services library provides a convenient account picker dialog you can invoke using AccountPicker. The result delivered to your activity from the account picker is the account name you'll use to request the OAuth 2.0 token in the next section.
Note: In order to use the APIs discussed here, you must include the Google Play services library with your project. If you haven't set up your project with the library yet, read the guide to Setup Google Play Services SDK.
Invoke the Account Picker
To open the account picker dialog that's managed by the Google Play services library, call startActivityForResult() using an Intent returned by AccountPicker.newChooseAccountIntent.
For example:
static final int REQUEST_CODE_PICK_ACCOUNT = 1000;
private void pickUserAccount() {
String[] accountTypes = new String[]{"com.google"};
Intent intent = AccountPicker.newChooseAccountIntent(null, null,
accountTypes, false, null, null, null, null);
startActivityForResult(intent, REQUEST_CODE_PICK_ACCOUNT);
}
When this code executes, a dialog appears for the user to pick an account. When the user selects the account, your activity receives the result in the onActivityResult() callback.
Most apps should pass the newChooseAccountIntent() method the same arguments shown in the above example, which indicate that:
• There is no currently selected account.
• There is no restricted list of accounts.
• The dialog should list only accounts from the "com.google" domain.
• Don't prompt the user to pick an account if there's only one available account (just use that one). However, even if only one account currently exists, the dialog may include an option for the user to add a new account.
• There is no custom title for the dialog.
• There is no specific auth token type required.
• There are no restrictions based on account features.
• There are no authenticator-specific options.
For more details about these arguments, see the newChooseAccountIntent() method.
Retrieve the Account Name
Once the user selects an account, your activity receives a call to its onActivityResult() method. The received Intent includes an extra for KEY_ACCOUNT_NAME, specifying the account name (an email address) you must use to acquire the OAuth 2.0 token.
Here's an example implementation of the callback onActivityResult() that receives the selected account:
String mEmail; // Received from newChooseAccountIntent(); passed to getToken()
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE_PICK_ACCOUNT) {
// Receiving a result from the AccountPicker
if (resultCode == RESULT_OK) {
mEmail = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);
// With the account name acquired, go get the auth token
getUsername();
} else if (resultCode == RESULT_CANCELED) {
// The account picker dialog closed without selecting an account.
// Notify users that they must pick an account to proceed.
Toast.makeText(this, R.string.pick_account, Toast.LENGTH_SHORT).show();
}
}
// Handle the result from exceptions
...
}
You can now pass the account name held by mEmail to GoogleAuthUtil.getToken() (which is what the getUsername() method does), but because it performs network transactions, this method should not be called from the UI thread. The next lesson shows how to create an AsyncTask to get the auth token on a separate thread.
Once you have retrieved the account name for the user's Google account, you can call GoogleAuthUtil.getToken(), which returns the access token string required by Google API services.
Calling this method is generally a straightforward procedure, but you must be aware that:
This lesson shows how you can gracefully handle these concerns by performing authentication in an AsyncTask and providing users with the appropriate information and available actions during known exceptions.
Note: The code shown in this lesson, using GoogleAuthUtil.getToken(), is appropriate when you will be requesting the OAuth token from an Activity. However, if you need to request the OAuth token from a Service, then you should instead use getTokenWithNotification(). This method works the same as GoogleAuthUtil.getToken(), but if an error occurs, it also creates an appropriate notification that allows the user can recover from the error. The sample available for download above includes code showing how to use this method instead.
Extend AsyncTask to Get the Auth Token
The AsyncTask class provides a simple way to create a worker thread for jobs that should not run on your UI thread. This lesson focuses on how to create such a thread to get your auth token; for a more complete discussion about AsyncTask, read Keeping Your App Responsive and the AsyncTask class reference.
The doInBackground() method in your AsyncTask class is where you should call the GoogleAuthUtil.getToken() method. You can also use it to catch some of the generic exceptions that may occur during your network transactions.
For example, here's part of an AsyncTask subclass that calls GoogleAuthUtil.getToken():
public class GetUsernameTask extends AsyncTask{
Activity mActivity;
String mScope;
String mEmail;
GetUsernameTask(Activity activity, String name, String scope) {
this.mActivity = activity;
this.mScope = scope;
this.mEmail = name;
}
/**
* Executes the asynchronous job. This runs when you call execute()
* on the AsyncTask instance.
*/
@Override
protected Void doInBackground(Void... params) {
try {
String token = fetchToken();
if (token != null) {
// **Insert the good stuff here.**
// Use the token to access the user's Google data.
...
}
} catch (IOException e) {
// The fetchToken() method handles Google-specific exceptions,
// so this indicates something went wrong at a higher level.
// TIP: Check for network connectivity before starting the AsyncTask.
...
}
return null;
}
/**
* Gets an authentication token from Google and handles any
* GoogleAuthException that may occur.
*/
protected String fetchToken() throws IOException {
try {
**return GoogleAuthUtil.getToken(mActivity, mEmail, mScope);**
} catch (UserRecoverableAuthException userRecoverableException) {
// GooglePlayServices.apk is either old, disabled, or not present
// so we need to show the user some UI in the activity to recover.
mActivity.handleException(userRecoverableException);
} catch (GoogleAuthException fatalException) {
// Some other type of unrecoverable exception has occurred.
// Report and log the error as appropriate for your app.
...
}
return null;
}
...
}
In order to call GoogleAuthUtil.getToken(), you must provide the app Context, the account name retrieved from the account picker, and the scope for your auth token request. The above sample code (and the attached sample) defines these arguments with class members that the host activity passes to the AsyncTask class constructor. For more information about setting the scope, see the Specifying Scopes section below.
Once you have an AsyncTask subclass defined, you can instantiate and execute an instance after you get the user's account name from the account picker. For example, back in the Activity class you can do something like this:
String mEmail; // Received from newChooseAccountIntent(); passed to getToken()
"oauth2:https://www.googleapis.com/auth/userinfo.profile";
/**
* Attempts to retrieve the username.
* If the account is not yet known, invoke the picker. Once the account is known,
* start an instance of the AsyncTask to get the auth token and do work with it.
*/
private void getUsername() {
if (mEmail == null) {
pickUserAccount();
} else {
if (isDeviceOnline()) {
**new GetUsernameTask(HelloActivity.this, mEmail, SCOPE).execute();**
} else {
Toast.makeText(this, R.string.not_online, Toast.LENGTH_LONG).show();
}
}
}
For information about how to check whether the device is currently online (as performed by the isDeviceOnline() method above), see the attached sample app or the Connecting to the Network lesson.
The only part left is how you should handle the exceptions that may occur when you call GoogleAuthUtil.getToken().
Specifying scopes
The scope string is used to specify which Google services can be accessed by an app using the requested auth token. An auth token can be associated with multiple scopes.
When specifying the scopes in your auth token request, prefix the scope string with "oauth2:" followed by a list of one or more OAuth scope values. Use a space to separate each scope value in the list. To see a list of valid OAuth scope values for Google services, browse the OAuth 2.0 Playground.
Tip: Specify "oauth2:<scope>" for a single scope. Specify "oauth2:<scope1> <scope2> <scopeN>" for multiple scopes (using a space to separate each scope).
For example, to access the Google Books API, the scope is "oauth2:https://www.googleapis.com/auth/books". To add an additional scope, say for Google+ login, your code might look like this:
private final static String BOOKS_API_SCOPE
= "https://www.googleapis.com/auth/books";
private final static String GPLUS_SCOPE
= "https://www.googleapis.com/auth/plus.login";
private final static String mScopes
= "oauth2:" + BOOKS_API_SCOPE + " " + GPLUS_SCOPE;
String token = GoogleAuthUtil.getToken(mActivity, mEmail, mScopes);
Handle Exceptions
As shown in the fetchToken() method above, you must catch all occurrences of GoogleAuthException when you call GoogleAuthUtil.getToken().
To provide users information and a proper solution to issues that may occur while acquiring the auth token, it's important that you properly handle the following subclasses of GoogleAuthException:
For example, the fetchToken() method in the above sample code catches any occurrence of UserRecoverableAuthException and passes it back to the activity with a method called handleException(). Here's what that method in the activity may look like:
static final int REQUEST_CODE_RECOVER_FROM_PLAY_SERVICES_ERROR = 1001;
/**
* This method is a hook for background threads and async tasks that need to
* provide the user a response UI when an exception occurs.
*/
public void handleException(final Exception e) {
// Because this call comes from the AsyncTask, we must ensure that the following
// code instead executes on the UI thread.
runOnUiThread(new Runnable() {
@Override
public void run() {
if (e instanceof GooglePlayServicesAvailabilityException) {
// The Google Play services APK is old, disabled, or not present.
// Show a dialog created by Google Play services that allows
// the user to update the APK
int statusCode = ((GooglePlayServicesAvailabilityException)e)
.getConnectionStatusCode();
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(statusCode,
HelloActivity.this,
REQUEST_CODE_RECOVER_FROM_PLAY_SERVICES_ERROR);
dialog.show();
} else if (e instanceof UserRecoverableAuthException) {
// Unable to authenticate, such as when the user has not yet granted
// the app access to the account, but the user can fix this.
// Forward the user to an activity in Google Play services.
Intent intent = ((UserRecoverableAuthException)e).getIntent();
startActivityForResult(intent,
REQUEST_CODE_RECOVER_FROM_PLAY_SERVICES_ERROR);
}
}
});
}
Notice that in both cases, the REQUEST_CODE_RECOVER_FROM_PLAY_SERVICES_ERROR request code is passed with the request to handle the exception with a dialog or activity. This way, when the user completes the appropriate action to resolve the exception, your onActivityResult() method receives an intent that includes this request code and you can try to acquire the auth token again.
For example, the following code is a complete implementation of onActivityResult() that handles results for both the REQUEST_CODE_PICK_ACCOUNT action and the REQUEST_CODE_RECOVER_FROM_PLAY_SERVICES_ERROR action, which occurs after the user completes one of the actions above to resolve an exception.
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE_PICK_ACCOUNT) {
// Receiving a result from the AccountPicker
if (resultCode == RESULT_OK) {
mEmail = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);
// With the account name acquired, go get the auth token
getUsername();
} else if (resultCode == RESULT_CANCELED) {
// The account picker dialog closed without selecting an account.
// Notify users that they must pick an account to proceed.
Toast.makeText(this, R.string.pick_account, Toast.LENGTH_SHORT).show();
}
} else if ((requestCode == REQUEST_CODE_RECOVER_FROM_AUTH_ERROR ||
requestCode == REQUEST_CODE_RECOVER_FROM_PLAY_SERVICES_ERROR)
&& resultCode == RESULT_OK) {
// Receiving a result that follows a GoogleAuthException, try auth again
getUsername();
}
}

Reflecting User Names Instead of IDs - Key Value Pairs in Dropdowns
#1
When building a chart that gets filtered by different User IDs using a Dropdown, more often than not you’ll want to hide the underlying User IDs. Instead, you can show the corresponding user names so that dashboards aren’t exposing actual User IDs. Accomplishing this is very straightforward in Chartio utilizing Key Value pairs!
( ⌒o⌒)人(⌒-⌒ )v
Once you've created your Dropdown, click the gear and hit Edit Filter. Then just make sure to drag the column you want reflected on the dashboard on the top of the Dimensions box:
Now you’re good to go! :smiley:
#2
Thanks Joe, nice tip! :slight_smile:
In your example
• If I use {DROPDOWN} for filtering or in a chart Title, I will see the User ID.
• Is there a way I can access the corresponding First Name of the chosen User?

Hi there!
The way this example is set up is that you’d see the First Name column displayed in the dropdown, while the User IDs are actually doing the filtering. In other words, the first column filters the chart, the second column displays values in the dropdown.
For a tad bit more explanation you can read our docs here:
Hopefully this helps - let me know if there’s any other questions!
#4
Thanks for the quick answer! :slight_smile:
My question was more related to the chart title of the chart where I do the filtering, not the filter itself. Let’s assume my filter is not multi select and looks like this:
Now, if I have chart which depends on that filter and want to use the {DROPDOWN} variable in the chart title, I would do something like this:
My (aesthetic) problem: I want the chart title to be City for the User Joe not City for the User 5672
Is there a way to archive that?
#5
Oh I see now - my mistake! Unfortunately we don’t support that yet - it’s a current feature request and I definitely see your point about how it could be useful. As of now, I’ve got to be the bearer of bad news, but I’ve added you as a watcher onto the ticket so that you can see any updates to it. Also, the more requesters, the more likely this will get developed!

ScrambleTextPlugin
Scrambles the text in a TextField with randomized characters (uppercase by default, but you can define lowercase or a set of custom characters), refreshing new randomized characters at regular intervals while gradually revealing your new text over the course of the tween (left to right). Visually it looks like a computer decoding a string of text. Great for rollovers.
You can simply pass a string of text directly as the scrambleText and it'll use the defaults for revealing it, or you can customize the settings by using a generic object with any of the following properties:
• text : String - the text that should replace the existing text in the TextField (required).
• chars : String - the characters that should be randomly swapped in to the scrambled portion the text. You can use "upperCase", "lowerCase", "upperAndLowerCase", or a custom string of characters, like "XO" or "TMOWACB", or "jompaWB!^", etc. (Default: "upperCase")
• tweenLength : Boolean - if the length of the replacement text is different than the original text, the difference will be gradually tweened so that the length doesn't suddenly jump. For example, if the original text is 50 characters and the replacement text is 100 characters, during the tween the number of characters would gradually move from 50 to 100 instead of jumping immediatley to 100. However, if you'd prefer to have it immediately jump, set tweenLength to false. (Default: true)
• revealDelay : Number - if you'd like the reveal (unscrambling) of the new text to be delayed for a certain portion of the tween so that the scrambled text is entirely visible for a while, use revealDelay to define the time you'd like to elapse before the reveal begins. For example, if the tween's duration is 3 seconds but you'd like the scrambled text to remain entirely visible for first 1 second of the tween, you'd set revealDelay to 1. (Default: 0)
• speed : Number - controls how frequently the scrambled characters are refreshed. The default is 1 but you could slow things down by using 0.2 for example (or any number). (Default: 1)
• delimiter : String - by default, each character is replaced one-by-one, but if you'd prefer to have things revealed word-by-word, you could use a delimiter of " " (space). (Default: "")
Usage
import com.greensock.TweenLite;
import com.greensock.plugins.TweenPlugin;
import com.greensock.plugins.ScrambleTextPlugin;
TweenPlugin.activate([ScrambleTextPlugin]); //activation is permanent in the SWF, so this line only needs to be run once.
//use the defaults
TweenLite.to(yourTextField, 1, {scrambleText:"THIS IS NEW TEXT"});
//or customize things:
TweenLite.to(yourTextField, 1, {scrambleText:{text:"THIS IS NEW TEXT", chars:"XO", revealDelay:0.5, speed:0.3}});

I have two samples ($n \approx 70$ in both cases). The means differ by about twice the pooled std. dev. The resulting $T$ value is approximately 10. Whilst it's great to know that I have conclusively shown that the means are not the same, this seems to me to be driven by the large n. Looking at histograms of the data I certainly do not feel that such as small p-value is really representative of the data and, to be honest, don't really feel comfortable quoting it. I'm probably asking the wrong question. What I'm thinking is: ok, the means are different but does that really matter as the distributions share a significant overlap?
Is this where Bayesian testing is useful? If so, where is a good place to start, a bit of googling hasn't yielded anything useful but I may not by asking the right question. If this is the wrong thing does anyone have any suggestions? Or is this simply a point for discussion as opposed to quantitative analysis?

• $\begingroup$ I just want to add to all the other answers that your first statement is wrong: you have NOT conclusively shown that the means are different. A t-test's p-value is telling you whether the probability of observing your data or more extreme values of it is likely/unlikely given the null hypothesis (which for the t-test is $\mu_A=\mu_B$, i.e., $H_0$: { "The means are equal" }), which does not mean that the means are, in fact, different. Also, I assume that you also performed an F-test in order to test the equality of the variances before doing the pooled variance t-test, right? $\endgroup$

• $\begingroup$ Your question is very good since it brings up an important distinction and it shows that you're actually thinking about your data rather than looking for some stars on a statistical output and declaring yourself done. As several answers point out, statistical significance is not the same as meaningful. And when you think about it, they can't be: how would a statistical procedure know that a statistically significant mean difference of 0.01 means something in Field A, but is meaninglessly small in Field B? $\endgroup$

• $\begingroup$ Fair enough, the langauge wasn't spot on but when the p-value is like the ones i'm getting I tend not to be too fussy about the words. I did do an F-test (and a QQ-plot). Its close enough for jazz, as they say. $\endgroup$

$\begingroup$ FWIW, if your means are 2 SD's apart, that seems like a pretty big difference to me. It will depend on your field, of course, but that's a difference people would easily notice w/ the naked eye (eg, the mean heights of US men & women age 20-29 differ by about 1.5 SD's.) IMO, if distributions don't overlap at all, you don't really need to do any data analyses; at a minimum, w/ $N$ as small as 6, $p$ will be <.05 if the distributions do not overlap. $\endgroup$ Sep 4, 2012 at 20:07

Let $\mu_1$ denote the mean of the first population and $\mu_2$ denote the mean of the second population. It seems that you've used a two-sample $t$-test to test whether $\mu_1=\mu_2$. The significant result implies that $\mu_1\neq\mu_2$, but the difference seems to be to small to matter for your application.
What've you encountered is the fact that statistically significant often can be something else than significant for the application. While the difference may be statistically significant it may still not be meaningful.
Bayesian testing won't solve that problem - you'll still just conclude that a difference exists.
There might however be a way out. For instance, for a one-sided hypothesis you could decide that if $\mu_1$ is $\Delta$ units greater than $\mu_2$ then that would be a meaningful difference that is large enough to matter for your application.
In that case you would test whether $\mu_1-\mu_2\leq \Delta$ instead of whether $\mu_1-\mu_2=0$. The $t$-statistic (assuming equal variances) would in that case be $$ T=\frac{\bar{x}_1-\bar{x}_2-\Delta}{s_p\sqrt{1/n_1+1/n_2}}$$ where $s_p$ is the pooled standard deviation estimate. Under the null hypothesis, this statistic is $t$-distributed with $n_1+n_2-2$ degrees of freedom.
An easy way of carrying out this test is to subtract $\Delta$ from your observations from the first population and then carry out a regular one-sided two-sample $t$-test.

It is valid to compare several approaches, but not with the aim of choosing the one that favours our desires/believes.
My answer to your question is: It is possible that two distributions overlap while they have different means, which seems to be your case (but we would need to see your data and context in order to provide a more precise answer).
I am going illustrate this using a couple of approaches for comparing normal means.
1. $t$-test
Consider two simulated samples of size $70$ from a $N(10,1)$ and $N(12,1)$, then the $t$-value is approximately $10$ as in your case (See the R code below).
rm(list=ls())
# Simulated data
dat1 = rnorm(70,10,1)
dat2 = rnorm(70,12,1)
set.seed(77)
# Smoothed densities
plot(density(dat1),ylim=c(0,0.5),xlim=c(6,16))
points(density(dat2),type="l",col="red")
# Normality tests
shapiro.test(dat1)
shapiro.test(dat2)
# t test
t.test(dat1,dat2)
However the densities show a considerable overlapping. But remember that you are testing a hypothesis about the means, which in this case are clearly different but, due to the value of $\sigma$, there is an overlap of the densities.
enter image description here
2. Profile likelihood of $\mu$
For a definition of the Profile likelihood and likelihood please see 1 and 2.
In this case, the profile likelihood of $\mu$ of a sample of size $n$ and sample mean $\bar{x}$ is simply $R_p(\mu)=\exp\left[-n(\bar{x}-\mu)^2\right]$.
For the simulated data, these can be calculated in R as follows
# Profile likelihood of mu
Rp1 = function(mu){
n = length(dat1)
md = mean(dat1)
return( exp(-n*(md-mu)^2) )
}
Rp2 = function(mu){
n = length(dat2)
md = mean(dat2)
return( exp(-n*(md-mu)^2) )
}
vec=seq(9.5,12.5,0.001)
rvec1 = lapply(vec,Rp1)
rvec2 = lapply(vec,Rp2)
# Plot of the profile likelihood of mu1 and mu2
plot(vec,rvec1,type="l")
points(vec,rvec2,type="l",col="red")
As you can see, the likelihood intervals of $\mu_1$ and $\mu_2$ do not overlap at any reasonable level.
3. Posterior of $\mu$ using Jeffreys prior
Consider the Jeffreys prior of $(\mu,\sigma)$
$$\pi(\mu,\sigma)\propto \dfrac{1}{\sigma^2}$$
The posterior of $\mu$ for each data set can be calculated as follows
# Posterior of mu
library(mcmc)
lp1 = function(par){
n=length(dat1)
if(par[2]>0) return(sum(log(dnorm((dat1-par[1])/par[2])))- (n+2)*log(par[2]))
else return(-Inf)
}
lp2 = function(par){
n=length(dat2)
if(par[2]>0) return(sum(log(dnorm((dat2-par[1])/par[2])))- (n+2)*log(par[2]))
else return(-Inf)
}
NMH = 35000
mup1 = metrop(lp1, scale = 0.25, initial = c(10,1), nbatch = NMH)$batch[,1][seq(5000,NMH,25)]
mup2 = metrop(lp2, scale = 0.25, initial = c(12,1), nbatch = NMH)$batch[,1][seq(5000,NMH,25)]
# Smoothed posterior densities
plot(density(mup1),ylim=c(0,4),xlim=c(9,13))
points(density(mup2),type="l",col="red")
Again, the credibility intervals for the means do not overlap at any reasonable level.
In conclusion, you can see how all these approaches indicate a significant difference of means (which is the main interest), despite the overlapping of the distributions.
$\star$ A different comparison approach
Judging by your concerns about the overlapping of the densities, another quantity of interest might be ${\mathbb P}(X<Y)$, the probability that the first random variable is smaller than the second variable. This quantity can be estimated nonparametrically as in this answer. Note that there are no distributional assumptions here. For the simulated data, this estimator is $0.8823825$, showing some overlap in this sense, while the means are significantly different. Please, have a look to the R code shown below.
# Optimal bandwidth
h = function(x){
n = length(x)
return((4*sqrt(var(x))^5/(3*n))^(1/5))
}
# Kernel estimators of the density and the distribution
kg = function(x,data){
hb = h(data)
k = r = length(x)
for(i in 1:k) r[i] = mean(dnorm((x[i]-data)/hb))/hb
return(r )
}
KG = function(x,data){
hb = h(data)
k = r = length(x)
for(i in 1:k) r[i] = mean(pnorm((x[i]-data)/hb))
return(r )
}
# Baklizi and Eidous (2006) estimator
nonpest = function(dat1B,dat2B){
return( as.numeric(integrate(function(x) KG(x,dat1B)*kg(x,dat2B),-Inf,Inf)$value))
}
nonpest(dat1,dat2)
I hope this helps.

Answering the Right Question
ok, the means are different but does that really matter as the distributions share a significant overlap?
Any test that asks whether group means are different will, when it works right, tell you whether means are different. It will not tell you that distributions of the data itself are different, since that is a different question. That question certainly depends on the whether the means are different but also on many other things that might be (incompletely) summarised as variance, skew, and kurtosis.
You correctly note that certainty about where the means are depends on the amount of data you have to estimate them, so having more data will allow you spot mean differences in more nearly overlapping distributions. But you wonder whether
such as small p-value is really representative of the data
Indeed it is not, at least not directly. And this is by design. It is representative (approximately speaking) of the certainty you can have that a particular pair of sample statistics of the data (not the data itself) are different.
If you wanted to represent the data itself in a more formal way than simply showing the histograms and testing moments of it, then perhaps a pair of density plots might be helpful. It rather depends really on the argument you are using the test to make.
A Bayesian Version
In all these respects, Bayesian difference 'tests' and T-tests will behave the same way because they are trying to do the same thing. The only advantages I can think of for using a Bayesian approach are: a) that it will be easy to do the test allowing possibly different variances for each group, and b) that it will focus on estimating the probable size of the difference in means rather than finding a p-value for some test of difference. That said, these advantages are pretty minor: e.g. in b) you could always report a confidence interval for the difference.
The quote marks above over 'tests' are deliberate. It is certainly possible to do Bayesian hypothesis testing, and people do. However, I would suggest that the comparative advantage of the approach is in the focus on building a plausible model of the data and communicating its important aspects with appropriate levels of uncertainty.
$\endgroup$

$\begingroup$
First of all, this is not a problem to pin on frequentist testing. The problem lies in the null hypothesis that the means are exactly equal. Therefore if the populations differ in means by any small amount and the sample size is large enough the chance to reject this null hypothesis is very high. Therefore the p-value for your test turned out to be very small. The culprit is the choice of the null hypothesis. Pick d>0 and take the null hypothesis to be that the means differ by less than d in absolute value. You pick d so that the real difference has to be satisfactorily large to reject. Your problem goes away. Bayesian testing does not solve your problem if you insist on a null hypothesis of exact equality of means.

Variables and Datatypes in JavaScript
Datatypes in JavaScript
There are majorly two types of languages. First, one is Statically typed language where each variable and expression type is already known at compile time. Once a variable is declared to be of a certain data type, it cannot hold values of other data types.Example: C, C++, Java.

brightness_4
code
// Java(Statically typed)
int x = 5 // variable x is of type int and it will not store any other type.
string y = 'abc' // type string and will only accept string values
chevron_right
Other, Dynamically typed languages: These languages can receive different data types over time. For example- Ruby, Python, JavaScript etc.
filter_none

close
play_arrow
link
brightness_4
code
// Javascript(Dynamically typed)
var x = 5; // can store an integer
var name = 'string'; // can also store a string.
chevron_right
JavaScript is dynamically typed (also called loosely typed) scripting language. That is, in javascript variables can receive different data types over time. Datatypes are basically typed of data that can be used and manipulated in a program.
The latest ECMAScript(ES6) standard defines seven data types: Out of which six data types are Primitive(predefined).
• Numbers: 5, 6.5, 7 etc.
• String: “Hello GeeksforGeeks” etc.
• Boolean: Represent a logical entity and can have two values: true or false.
• Null: This type has only one value : null.
• Undefined: A variable that has not been assigned a value is undefined.
• Object: It is the most important data-type and forms the building blocks for modern JavaScript. We will learn about these data types in details in further articles.
Variables in JavaScript:
Variables in JavaScript are containers which hold reusable data. It is the basic unit of storage in a program.
• The value stored in a variable can be changed during program execution.
• A variable is only a name given to a memory location, all the operations done on the variable effects that memory location.
• In JavaScript, all the variables must be declared before they can be used.
Before ES2015, JavaScript variables were solely declared using the var keyword followed by the name of the variable and semi-colon. Below is the syntax to create variables in JavaScript:
var var_name;
var x;
The var_name is the name of the variable which should be defined by the user and should be unique. These type of names are also known as identifiers. The rules for creating an identifier in JavaScript are, the name of the identifier should not be any pre-defined word(known as keywords), the first character must be a letter, an underscore (_), or a dollar sign ($). Subsequent characters may be any letter or digit or an underscore or dollar sign.
Notice in the above code sample, we didn’t assign any values to the variables.We are only saying they exist.If you were to look at the value of each variable in the above code sample,it would be undefined.
We can initialize the variables either at the time of declaration or also later when we want to use them. Below are some examples of declaring and initializing variables in JavaScript:
// declaring single variable
var name;
// declaring multiple variables
var name, title, num;
// initializng variables
var name = "Harsh";
name = "Rakesh";
Javascript is also known as untyped language. This means, that once a variable is created in javascript using the keyword var, we can store any type of value in this variable supported by javascript. Below is the example for this:
// creating variable to store a number
var num = 5;
// store string in the variable num
num = "GeeksforGeeks";
The above example executes well without any error in JavaScript unlike other programming languages.
Variables in JavaScript can also evaluate simple mathematical expressions and assume its value.
// storing a mathematical expression
var x = 5 + 10 + 1;
console.log(x); // 16
After ES2015,we now have two new variable containers : let and const. Now we shall look at both of them one by one. The variable type Let shares lots of similarities with var but unlike var it has scope constraints. To know more about them visit let vs var. Let’s make use of let variable:
// let variable
let x; // undefined
let name = 'Mukul';
// can also declare multiple vlaues
let a=1,b=2,c=3;
// assignment
let a = 3;
a = 4; // works same as var.
Const is another variable type assigned to data whose value cannot and will not change throught the script.
// const variable
const name = 'Mukul';
name = 'Mayank'; // will give Assignment to constant variable error.
Variable Scope in Javascript
Scope of a variable is the part of the program from where the variable may directly be accessible.
In JavaScript, there are two types of scopes:
1. Global Scope – Scope outside the outermost function attached to Window.
2. Local Scope – Inside the function being executed.
Let’s look at the code below. We have a global variable defined in first line in global scope. Then we have a local variable defined inside the function fun().
filter_none
edit
close
play_arrow
link
brightness_4
code
let globalVar = "This is a global variable";
function fun() {
let localVar = "This is a local variable";
console.log(globalVar);
console.log(localVar);
}
fun();
chevron_right
Output:
When we execute the function fun(), the output shows that both global as well as local variables are accessible inside the function as we are able to console.log them. This shows that inside the function we have access to both global variables (declared outside the function) and local variables (declared inside the function).Let’s move the console.log statements outside the function and put them just after calling the function.
filter_none
edit
close
play_arrow
link
brightness_4
code
let globalVar = "This is a global variable";
function fun() {
let localVar = "This is a local variable"
}
fun();
console.log(globalVar);
console.log(localVar);
chevron_right
Output:
We are still able to see the value of the global variable, but for local variable console.log throws an error. This is because now the console.log statements are present in global scope where they have access to global variables but cannot access the local variables.
Also, any variable defined in a function with the same name as a global variable takes precedence over the global variable, shadowing it.To understand variable scopes in details in JavaScript, please refer to the article on understanding variable scopes in Javascript.

Adding OwnerRez widgets to WordPress
For an overview on OwnerRez Widgets, widget setup, etc. look at the Setting up widgets for inquiries, bookings and availability.
There are two main ways to add OwnerRez Widgets to your WordPress site -- shortcodes via Shortcoder or page builder plugins via HTML widgets. I'll cover both here, and two common page builders (Beaver Builder and SiteOrigin Page Builder). If you have questions about adding OwnerRez Widgets via a different method, let us know.
Note: these guides are oriented around setup of widgets for a couple of properties. If you've got many properties and want a parameterized setup that is possible but a bit more complex. Contact us and we'll walk you through that process.
Shortcodes
These steps assume you've already created a page where you want to embed OwnerRez widgets.
1. Install the Shortcoder plugin if it's not currently installed.
2. Go to Settings > Shortcoder to create a new shortcode:
3. Name the shortcode. Note the "Your shortcode is" reference to the right of the Title field -- you'll use this to embed the shortcode later.
4. Copy the widget code from the OwnerRez widget and paste it in to the Content box.
5. Create the Shortcode
6. Now go to the page where you want to add the widget:
7. Enter the "Your shortcode is" reference from the Create shortcode operation
8. Save/Publish the page and view it:
Beaver Builder
These steps assume you've already got the Beaver Builder plugin installed, and have created a page where you want to embed OwnerRez widgets.
1. Open Beaver Builder to the page you want to edit.
2. Click Add Content in the top right:
3. Drag an HTML module from the Basic Modules section:
4. Copy the widget code from the OwnerRez Widget and paste it into the HTML Settings box:
5. Save the HTML settings
6. Save/Publish the page and view it:
SiteOrigin Page Builder
These steps assume you've already got the SiteOrigin Page Builder plugin installed, and have created a page where you want to embed OwnerRez widgets.
1. Open SiteOrigin Editor to the page you want to edit.
2. Click Add Widget to add a new widget:
3. Select the Text widget and add it:
4. Hover over the Text widget and Edit it:
5. Copy the widget code from the OwnerRez Widget and paste it into the Content box:
6. Save the Text widget
7. Save/Publish the page and view it:

In this post I'll write about how to reduce a bit of boilerplate code when writing tests in Spring Framework in a situation where we don't want to bring up the whole Spring context in order to test if only a subset of components are working together correctly.
Our goal will be to have Spring load only the components that we are interested in testing, mock out everything else and do it in a simple and readable way.
Let's start with an example. Our example application has a UserService with a registerNewUser method. Whenever a new user is added to the system, UserService's registerNewUser method is called. This method adds the user to the system, hashes user's password, stores user data to the database, updates application's user statistics and sends out confirmation e-mail. To accomplish these tasks, UserService depends on PasswordEncoder, UserRepository, StatisticsService and EmailService.
We want to write an integration test that will verify that when registerNewUser is called, the user is indeed stored correctly to the database and user password is hashed. To do this, we want actual UserService implementation brought up in our test Spring context, along with PasswordEncoder and persistence related components and have everything else mocked out (side note: I'm using the term mock here, but since we're not verifying interactions with mock objects in the example tests, some testing vocabularies would refer to these kind of test objects as dummy objects).
To mock out the beans we'll be using Mockito library. Our JUnit test will be run with SpringJUnit4ClassRunner. Demo application's code is available at GitHub.
Here's the test class:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader=AnnotationConfigContextLoader.class)
public class UserServiceImplIntegrationTest {
@Autowired
UserService userService;
@Autowired
UserRepository userRepository;
@Transactional
@Test
public void testRegisterNewUser() {
final String userName = "someone";
final String password = "somepass";
userService.registerNewUser(new User("[email protected]", userName, password));
User user = userRepository.findByUserName(userName);
Assert.assertNotNull(user);
Assert.assertTrue(SCryptUtil.check(password, user.getPassword()));
}
@Configuration
@Import(TestAppConfig.class)
static class ContextConfiguration {
@Bean
public UserService userService() {
return new UserServiceImpl();
}
@Bean
public PasswordEncoder passwordEncoder() {
return new SCryptPasswordEncoder();
}
@Bean
public EmailService emailService() {
return Mockito.mock(EmailService.class);
}
@Bean
public StatisticsService statisticsService() {
return Mockito.mock(StatisticsService.class);
}
}
}
Let's examine the code:
With @ContextConfiguration(loader=AnnotationConfigContextLoader.class) we instruct Spring to load test context configuration from the annotated class. We have defined the configuration class as a static inner class of our test class (ContextConfiguration). We import common configuration that will be shared among different integration tests form TestAppConfig.class. In the ContextConfiguration we define the beans whose actual implementation will participate in the integration test (UserServiceImpl and SCryptPasswordEncoder) and we mock out their dependencies (EmailService, StatisticsService). The inspiration for this pattern of writing integration tests that combine actual and mocked beans originate from great answers found in this stack overflow question: Injecting Mockito mocks into a Spring bean.
The idea is to keep common configuration that we plan to reuse between various tests in TestAppConfig.class (in our example, TestAppConfig contains test database, JPA and Spring-data configuration) and add keep per test specific configuration in an inner class of the test class. We also manually define beans that we need to mock out in order for Spring to satisfy all the dependencies of the beans we plan to test.
This works just fine, expect in certain more complex integration tests, there will be a lot of beans to be mocked out, and we have to write lots of boilerplate code to define those. For example, to mock out EmailService class we write:
@Bean
public EmailService emailService() {
return Mockito.mock(EmailService.class);
}
Characters "EmailService" are typed three times (Type definition, method name and as a parameter to mock method) and we hat to write 4 lines of code. If there's 10 beans to mock out, that's a lot of typing! Is there a way to make things more concise? It turns out there is, using the ImportBeanDefinitionRegistrar. We will create an annotation that we'll use to specify which classes we plan to mock out, and then implement ImportBeanDefinitionRegistrar that will look for the annotation and register bean definitions we specified as a mocked beans.
Here's the custom annotation:
@Import(MockImportRegistar.class)
@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface MockedBeans {
/**
* Types that need to be mocked.
* @return
*/
Class<?>[] value() default {};
}
Here's the code for ImportBeanDefinitionRegistrar implementation (note that we referenced MockImportRegistar with @Import in MockedBean annotation above):
public class MockImportRegistar implements ImportBeanDefinitionRegistrar {
@Override
public void registerBeanDefinitions(AnnotationMetadata importingClassMetadata, BeanDefinitionRegistry registry) {
if (importingClassMetadata.isAnnotated(MockedBeans.class.getName())) {
Object mockedBeanTypesValue = importingClassMetadata.getAnnotationAttributes(MockedBeans.class.getName()).get("value");
if (mockedBeanTypesValue instanceof Class<?>[]) {
Class<?>[] mockedBeanTypes = (Class<?>[]) mockedBeanTypesValue;
if (mockedBeanTypes != null && mockedBeanTypes.length > 0) {
mockSpecifiedBeanTypes(registry, mockedBeanTypes);
}
}
}
}
private void mockSpecifiedBeanTypes(BeanDefinitionRegistry registry, Class<?>[] mockedBeanTypes) {
for (Class<?> mockedType : mockedBeanTypes) {
registry.registerBeanDefinition("mock" + mockedType.getSimpleName(),
BeanDefinitionBuilder
.rootBeanDefinition(Mockito.class)
.setFactoryMethod("mock")
.addConstructorArgValue(mockedType.getName())
.getBeanDefinition()
);
}
}
}
Now that have defined the annotation and the registrar we can rewrite the ContextConfiguration like this:
@Configuration
@Import(TestAppConfig.class)
@MockedBeans({EmailService.class, StatisticsService.class})
static class ContextConfiguration {
@Bean
public UserService userService() {
return new UserServiceImpl();
}
@Bean
public PasswordEncoder passwordEncoder() {
return new SCryptPasswordEncoder();
}
}
Beans that we need to be mocked are now defined using our @MockedBeans annotation. I find this approach more concise, simpler and easier to maintain, especially for more complex integration tests.

Can a bad RAM stick stop a computer from starting up?
Hello,
Can a bad RAM stick stop a computer from starting up? When I power up all the fans and driver run.
Best Buy checked the power supply and it is ok.
Yellow light below power button comes on for a couple minutes. no beeps though. Monitor says power saving mode and goes blank.
Checked out hard drive in a box on the lap top it is good all the files are there. It acts as though it cant find the system bios to start up the OS.
Can a bad ram stick cause this or can the processor find what it needs to run directly from the hard drive?

Is this a good question?

MacBook Air's have soldered on DRAM are you sure you have a MacBook Air?
The MacBook Air's do have replaceable HD or SSD units (depending on the model). But given your symptoms it sounds like you have a battery or EFI firmware issue.
It would be helpful if you could supply us the last four digits of your serial number so we can correctly identify your model as well as what OS-X you are running.

Yes. Best Buy should be able to run AHT on it. If they can't (don't know why they didn't) then you may have logic board problems. Each machine goes through a POST (power on self test) that's when the EFI (mac for BIOS) checks and reports hardware errors (though sometimes the is no error code for the problem e.g. too much current draw).
Disconnect all peripherals before attempting to boot.
If this answer is acceptable please remember to return and mark it.

intersect
Set intersection of two arrays
Description
example
C = intersect(A,B) returns the data common to both A and B, with no repetitions. C is in sorted order.
• If A and B are tables or timetables, then intersect returns the set of rows common to both tables. For timetables, intersect takes row times into account to determine equality, and sorts the output timetable C by row times.
example
C = intersect(A,B,setOrder) returns C in a specific order. setOrder can be 'sorted' or 'stable'.
C = intersect(A,B,___,'rows') and C = intersect(A,B,'rows',___) treat each row of A and each row of B as single entities and return the rows common to both A and B, with no repetitions. You must specify A and B and optionally can specify setOrder.
The 'rows' option does not support cell arrays, unless one of the inputs is either a categorical array or a datetime array.
example
[C,ia,ib] = intersect(___) also returns index vectors ia and ib using any of the previous syntaxes.
• Generally, C = A(ia) and C = B(ib).
• If the 'rows' option is specified, then C = A(ia,:) and C = B(ib,:).
• If A and B are tables or timetables, then C = A(ia,:) and C = B(ib,:).
example
[C,ia,ib] = intersect(A,B,'legacy') and [C,ia,ib] = intersect(A,B,'rows','legacy') preserve the behavior of the intersect function from R2012b and prior releases.
The 'legacy' option does not support categorical arrays, datetime arrays, duration arrays, tables, or timetables.

Two rows that have the same values, but different names, are considered equal. Therefore, we discover that Betty, A(3,:), and Meg, B(1,:) have the same gender, age, and height.
Create two matrices with rows in common.

A and B do not need to have the same number of rows, but they must have the same number of columns.
Use the setOrder argument to specify the ordering of the values in C.
Specify 'stable' if you want the values in C to have the same order as in A.
A = [7 1 7 7 4]; B = [7 0 4 4 0];

Input Arguments
collapse all
Input arrays. If you specify the 'rows' option, then A and B must have the same number of columns.
A and B must be of the same class with the following exceptions:
• logical, char, and all numeric classes can combine with double arrays.
• Cell arrays of character vectors can combine with character arrays or string arrays.
• Categorical arrays can combine with character arrays, cell arrays of character vectors, or string arrays.
• Datetime arrays can combine with cell arrays of date character vectors or single date character vectors.
There are additional requirements for A and B based on data type:
• If A and B are both ordinal categorical arrays, they must have the same sets of categories, including their order. If neither A nor B are ordinal, they need not have the same sets of categories, and the comparison is performed using the category names. In this case, the categories of C consist of the categories of A followed by the categories of B that are not in A. The categories are in the same order as in A and B, and the category order is used for sorting C.
• If A and B are tables or timetables, they must have the same variable names (except for order). For tables, row names are ignored, so that two rows that have the same values, but different names, are considered equal. For timetables, row times are taken into account, so that two rows that have the same values, but different times, are not considered equal.
• If A and B are datetime arrays, they must be consistent with each other in whether they specify a time zone.
A and B also can be objects with the following class methods:
• sort (or sortrows for the 'rows' option)
• ne
The object class methods must be consistent with each other. These objects include heterogeneous arrays derived from the same root class. For example, A and B can be arrays of handles to graphics objects.
Order flag, specified as 'sorted' or 'stable', indicates the order of the values (or rows) in C.
FlagDescription
'sorted'
The values (or rows) in C return in sorted order as returned by sort.
Example
C = intersect([7 0 1 5],[0 2 7 5],'sorted')
C =
0 5 7
'stable'
The values (or rows) in C return in the same order as they appear in A.
Example
C = intersect([7 0 1 5],[0 2 7 5],'stable')
C =
7 0 5
Data Types: char | string
Output Arguments
collapse all
Data common to A and B, returned as a vector, matrix, or table. If the inputs A and B are tables or timetables, then the order of the variables in C is the same as the order of the variables in A.
The following describes the shape of C when the inputs are vectors or matrices and when the 'legacy' flag is not specified:
• If the 'rows' flag is not specified, then C is a column vector unless both A and B are row vectors, in which case C is a row vector.
• If the 'rows' flag is specified, then C is a matrix containing the rows in common from A and B.
The class of the inputs A and B determines the class of C:
• If the class of A and B are the same, then C is the same class.
• If you combine a char or nondouble numeric class with double, then C is the same class as the nondouble input.
• If you combine a logical class with double, then C is double.
• If you combine a cell array of character vectors with char, then C is a cell array of character vectors.
• If you combine a categorical array with a character vector, cell array of character vectors, or string, then C is a categorical array.
• If you combine a datetime array with a cell array of date character vectors or single date character vector, then C is a datetime array.
• If you combine a string array with a character vector or cell array of character vectors, then C is a string array.
Index to A, returned as a column vector when the 'legacy' flag is not specified. ia identifies the values (or rows) in A that are common to B. If there is a repeated value (or row) in A, then ia contains the index to the first occurrence of the value (or row).
Index to B, returned as a column vector when the 'legacy' flag is not specified. ib identifies the values (or rows) in B that are common to A. If there is a repeated value (or row) in B, then ib contains the index to the first occurrence of the value (or row).
Tips
• To find the intersection with respect to a subset of variables from a table or timetable, you can use column subscripting. For example, you can use intersect(A(:,vars),B(:,vars)), where vars is a positive integer, a vector of positive integers, a variable name, a cell array of variable names, or a logical vector. Alternatively, you can use vartype to create a subscript that selects variables of a specified type.

Description
<source lang="c"> u_long baud = 115200;
NutRegisterDevice(&DEV_DEBUG, 0, 0); freopen(DEV_DEBUG_NAME, "w", stdout); _ioctl(_fileno(stdout), UART_SETSPEED, &baud); </source>
Set up the debug device so we can output to the terminal. See the Hello World! sample for more details.
<source lang="c"> /* NOTE: This assumes the hardware codec is present */
if (NutRegisterSpiDevice(&devSpiVsCodec0, &DEV_SPIBUS, 1)) {
puts("Codec unavailable.\n");
} </source>
This line registers the VS Codec. Note that we don't use the normal NutRegisterDevice here. Since the VS Codec is a device on the SPI bus, we have to register it using NutRegisterSpiDevice. The parameter DEV_SPIBUS passes the bus we want to register it to.
Alternatively you can use a software decoder, if your target board can provide sufficient processing power. For ARM-based boards, Nut/OS offers the Helix MP3 decoder. Note, that this is distributed under an incompatible license and you need to this license in the Nut/OS Configurator (last item in the tree).
To register the Helix decoder, use
<source lang="c"> if (NutRegisterDevice(&devHelixCodec, 0, 0)) {
puts("Audio codec not available");
} </source>
There had been a few problems with this decoder lately. Recent Nut/OS versions (4.8 up to 5.0) do not allow to register bit-banging I2C drivers, if I2C hardware (TWI in Atmel terms) is available on that CPU. Check the code repository at [1] for the latest updates of the files dev/hxcodec.c and arch/arm/dev/tlv320dac.c.
<source lang="c"> /* Register UROM device */
if (NutRegisterDevice(&devUrom, 0, 0)) {
printf("UROM error\n");
} </source>
Now we register the uROM device. For more information on uROM access see the Reading UROM Files article.
<source lang="c"> decoder = _open("audio0", _O_WRONLY | _O_BINARY); fh = _open("UROM:example.mp3", _O_RDONLY | _O_BINARY); </source>
For the MP3 Codec to play, we need to pass data directly to it. To achieve this, we open both the decoder (audio0) and the mp3 file we want to use (example.mp3) via the open command. This is a lower level command than fopen and does not return a file pointer but a handle of type integer.
<source lang="c"> for (;;) {
n = _read(fh, buff, 512);
if (n <= 0) {
break;
}
_write(decoder, buff, n);
_write(decoder, NULL, 0);
} </source>
This loop does the actual MP3 playing. It first reads 512 bytes from the MP3 file and stores the number of bytes read in n.
Before writing the data the decoder, we have to make sure there is actually data left for writing. We do this by checking n (the number of bytes read) for a size <= 0. If it is, we have no more data left to write and can safely exit the play loop.
If there's data left to write, we write it to the decoder.
The line "_write(decoder, NULL, 0);" is something special. Usually all data transfers are buffered, sometimes resulting in data that is not yet written when the _write command returns control to your program. By writing a NULL pointer to the audio device, we instruct Nut/OS to flush all data to the decoder. Do NOT use this elsewhere as this is a special trick of Nut/OS and will result in bugs and crashes if used anywhere else.
<source lang="c"> _close(decoder); _close(fh); </source>
We're done playing, now close our open files.
It may happen, that the decoder stops playing before the end of the file has been reached. This had been an issue with early VS10XX hardware drivers and, at the time of this writing, is a problem with the Helix decoder. To force playing up to the end of the file, use
<source lang="c"> int i;
memset(buff, 0, sizeof(buff)); for (i = 0; i < 8; i++) {
_write(dh, buff, sizeof(buff));
} </source>
immediately before closing the decoder.

Algorithmic puzzles are puzzles involving well-defined procedures for solving problems. This book will provide an enjoyable and accessible introduction to algorithmic puzzles that will develop the reader's algorithmic thinking. The first part of this book is a tutorial on algorithm design strategies and analysis techniques. Algorithm design strategies a exhaustive search, backtracking, divide-and-conquer and a few others a are general approaches to designing step-by-step instructions for solving problems. Analysis techniques are methods for investigating such procedures to answer questions about the ultimate result of the procedure or how many steps are executed before the procedure stops. The discussion is an elementary level, with puzzle examples, and requires neither programming nor mathematics beyond a secondary school level. Thus, the tutorial provides a gentle and entertaining introduction to main ideas in high-level algorithmic problem solving. The second and main part of the book contains 150 puzzles, from centuries-old classics to newcomers often asked during job interviews at computing, engineering, and financial companies. The puzzles are divided into three groups by their difficulty levels. The first fifty puzzles in the Easier Puzzles section require only middle school mathematics. The sixty puzzle of average difficulty and forty harder puzzles require just high school mathematics plus a few topics such as binary numbers and simple recurrences, which are reviewed in the tutorial. All the puzzles are provided with hints, detailed solutions, and brief comments. The comments deal with the puzzle origins and design or analysis techniques used in the solution. The book should be of interest to puzzle lovers, students and teachers of algorithm courses, and persons expecting to be given puzzles during job interviews.This book will provide an enjoyable and accessible introduction to algorithmic puzzles that will develop the readera#39;s algorithmic thinking. The first part of this book is a tutorial on algorithm design strategies and analysis techniques.

There is an app on the Market right now for this but it involves doing some coding on your own as it is meant for developers. If you follow the instructions on the tutorials though, I have read that the results work quite nicely but they say that first and foremost, the app and tutorials are for developers who want to develop their own zoom or 3D list software (also included in the app). Hope this helps!

So in the near future someone will make this app for us to zoom like this and put it on the Market ? If I have understood what you are saying, because I dont want to mess anything with my phone on my own :)

I think that's the general idea, that it'll be released in an update or something.
I think they said in one of the tutorials that it shouldn't mess up anything on your phone but that you shouldn't attempt it without having some kind of background. I was tempted to try but then decided that I was doing alright without it so far, so I could wait until it's officially released by SE or on the Market.

Problema di Basilea
Da Wikipedia, l'enciclopedia libera.
Il problema di Basilea è un famoso problema dell’analisi, proposto per la prima volta da Pietro Mengoli nel 1644 e risolto da Eulero nel 1735. Il problema aveva resistito agli attacchi dei più grandi matematici dell’epoca quindi la soluzione di Eulero (ancora ventottenne) suscitò stupore e ammirazione. Il problema di Basilea chiede di scoprire la forma chiusa (cioè la formula) a cui tende la somma degli inversi di tutti i quadrati dei numeri naturali, cioè la somma precisa della serie infinita:
\sum_{n=1}^\infin \frac{1}{n^2} =
\frac{1}{1^2} + \frac{1}{2^2} + \cdots
La serie è approssimativamente uguale a 1,644934. Il problema di Basilea chiede la somma esatta di questa serie (nella forma chiusa). Eulero dimostrò che la somma esatta è \frac{\pi^2}{6} e annunciò questa scoperta nel 1735. Le sue dimostrazioni erano basate su passaggi non chiariti appieno. Per una dimostrazione rigorosa bisognerà aspettare fino al 1741.
Indice
[modifica] La funzione zeta di Riemann
La funzione zeta di Riemann è ζ(s) è una delle più importanti della matematica in parte perché è in relazione con la distribuzione dei numeri primi. La funzione è definita per tutti i numeri complessi con parte reale > 1 dalla formula:
\zeta(s) = \sum_{n=1}^\infin \frac{1}{n^s}.
Con s = 2, noi vediamo che ζ(2) è uguale alla somma degli inversi dei quadrati di tutti i numeri naturali.
\zeta(2) =
\sum_{n=1}^\infin \frac{1}{n^2} =
\frac{1}{1^2} + \frac{1}{2^2} + \frac{1}{3^2} + \frac{1}{4^2} + \cdots \approx 1,644934.
Come sappiamo che converge? Si può dimostrare che essa converge con la diseguaglianza:
\sum_{n=1}^N \frac{1}{n^2} < 1 + \sum_{n=2}^N \frac{1}{n(n-1)}
= 1 + \sum_{n=2}^N \left( \frac{1}{n-1} - \frac{1}{n} \right)
= 1 + 1 - \frac{1}{N} \; \stackrel{N \to \infty}{\longrightarrow} \; 2.
e grazie al fatto che tutti i suoi termini sono positivi. Inoltre tale disuguaglianza ci dà il limite superiore ζ(2) < 2.
La dimostrazione di convergenza è anche facilmente ottenibile sostituendo a ciascuna frazione non contenente una potenza di due la frazione contente potenza di due e di valore immediatamente superiore alla frazione sostituita. In tal modo si ottiene una serie che ha somme parziali sempre superiori alla serie data:
\sum_{n=1}^\infin \frac{1}{n^2} =
\frac{1}{1^2} + \frac{1}{2^2} + \frac{1}{3^2} + \frac{1}{4^2} + \cdots \frac{1}{n^2} <
\frac{1}{1^2} + \frac{1}{2^2} + \frac{1}{2^2} + \frac{1}{4^2}+ \frac{1}{4^2}+ \frac{1}{4^2}+ \frac{1}{4^2}+ \cdots \frac{2^n}{{2^n}^2}
Si nota facilmente che la nuova serie equivale alla serie degli inversi delle potenze di due:
\sum_{n=0}^\infin \frac{1}{2^n} =
\frac{1}{2^0}+ \frac{1}{2^1} + \frac{1}{2^2} + \frac{1}{2^3} + \frac{1}{2^4} + \cdots \frac{1}{{2^n}}
che, come noto, converge a 2.
Ma se tale serie è convergente, allora lo è anche la serie di partenza in quanto le sue somme parziali sono sempre inferiori.
[modifica] La dimostrazione di Eulero
La dimostrazione di Eulero è intelligente e originale. Essenzialmente egli suppose che le regole dei polinomi finiti fossero valide anche per le serie infinite. Naturalmente il ragionamento originale di Eulero richiede una dimostrazione di questo, ma anche senza giustificazione, semplicemente ottenendo un valore prossimo a quello ottenuto col calcolo, egli poteva essere piuttosto sicuro della correttezza del suo risultato. Per seguire la dimostrazione di Eulero, bisogna ricordare lo sviluppo in serie di Taylor della funzione seno centrato in 0:
\sin(x) = x - \frac{x^3}{3!} + \frac{x^5}{5!} - \frac{x^7}{7!} + \cdots.
Dividendo per x entrambi i termini, abbiamo:
\frac{\sin(x)}{x} = 1 - \frac{x^2}{3!} + \frac{x^4}{5!} - \frac{x^6}{7!} + \cdots.
Le radici di questo polinomio sono π, 2π, 3π.... Poniamo ora z = x^2 e abbiamo:
\frac{\sin(x)}{x} = 1 - \frac{z}{3!} + \frac{z^2}{5!} - \frac{z^3}{7!} + \cdots.
Le radici di questo polinomio (per la sostituzione operata) sono: π2, 4π2, 9π2... Per le Formule di Viète abbiamo che, se un polinomio ha il termine costante uguale a 1, la somma degli inversi delle sue radici è uguale al coefficiente del termine lineare cambiato di segno. (in altre parole la somma degli inversi delle radici del polinomio a_n{x^n}+...+a_3{x^3}+a_2{x^2}+ bx +1 dà come risultato -b) Supponiamo di poter applicare le regole dei polinomi finiti anche per questo polinomio infinito. Abbiamo che:
+ \frac{1}{3!} = \frac{1}{6} = \frac{1}{\pi^2} + \frac{1}{4\pi^2} + \frac{1}{9\pi^2} + \frac{1}{16\pi^2} + \cdots
Moltiplicando entrambi i termini per \pi^2 otteniamo:
\frac{\pi^2}{6} = 1 + \frac{1}{4} + \frac{1}{9} + \frac{1}{16} + \cdots = \sum_{n=1}^\infin \frac{1}{n^2}

[modifica] Una dimostrazione rigorosa
La seguente dimostrazione di ζ(2) = π2/6 è la prova più semplice disponibile; mentre la maggior parte delle prove utilizzano i risultati dalla matematica avanzata, quali analisi di Fourier, analisi complessa e calcolo a più variabili.
[modifica] Storia della dimostrazione
L'origine della prova è poco chiara. È comparsa nel giornale Eureka in 1982, attribuita a John Scholes, ma la prova era “conoscenza comune” a Cambridge verso la fine degli anni '60.
[modifica] Che cosa bisogna conoscere
Per capire la dimostrazione dobbiamo conoscere le seguenti nozioni
(Dove il coefficiente binomiale è: {n \choose k}=\frac{n!}{k!(n-k)!}.
• La funzione cot2 x ha una corrispondenza biunivoca nell’intervallo (0, π/2).
• Dimostrazione: supponiamo che cot2 x = cot2 y per alcuni x e y nell'intervallo (0, π/2). Avvalendoci della definizione di cotangente cot x = (cos x)/(sin x) e dell'identità trigonometrica cos2 x = 1 − sin2 x, vediamo che (sin2 x)(1 − sin2 y) = (sin2 y)(1 − sin2 x). Aggiungendo (sin2 x)(sin2 y) a entrambi i termini, otteniamo sin2 x = sin2 y. Poiché la funzione seno non è mai negativa in (0, π/2), si ha sin x = sin y, ma è geometricamente evidente (per esempio dando un'occhiata alla circonferenza goniometrica) che la funzione seno è crescente nell'intervallo (0, π/2), per cui x = y.
• Se p(t) è un polinomio di grado m, p ha esattamente m radici in C, contate con molteplicità.
• Se p(t) = amtm + am − 1tm − 1 + ... + a1t + a0, dove am ≠ 0, allora la somma delle radici di p (contando le molteplicità) è −am − 1/am
• Dimostrazione: Se am = 1, allora p(t) = prodotto di tutti i (ts), dove s spazia tra tutte le radici di p. Espandendo questo prodotto, si vede che il coefficiente di tm − 1 è l'opposto della somma di tutte le altre radici. Se am ≠ 1, allora possiamo dividere per esso ogni termine, ottenendo un nuovo polinomio con le stesse radici, il cui coefficiente di partenza è 1; reiterando lo stesso ragionamento, si vede che la somma di tutte le radici del p(t) = somma di tutte le radici del nuovo polinomio = −am − 1/am.
• L’identità trigonometrica csc 2 x = 1 + cot 2 x.
• Dimostrazione: È conseguenza dell'identità fondamentale 1 = sin2 x + cos2 x dove ogni termine è stato diviso per sin2 x.
• Per un numero reale x compreso tra 0 e π/2, abbiamo la diseguaglianza cot 2 x < 1/x2 < csc2 x.
• Per x piccoli, è ampiamente dimostrato che 0 < sin x < x < tan x, come è possibile vedere qui:
Circle-trig6.svg
Per notare che 0 < sin x < x, si osservi il fatto che nella figura sin θ è la lunghezza della linea AC, e θ è la lunghezza dell'arco circolare AD.
Per notare che x < tan x, si osservi che l'area del triangolo OAE è tan(θ)/2, l'area del settore OAD è θ/2, e che il settore è contenuto nel triangolo.
Ora, si consideri il reciproco di ogni elemento trigonometrico fin qui nominato, e se ne calcoli il quadrato. Si tenga altresì presente che la disequazione, in presenza dei reciproci, cambia direzione.
• Dati tre numeri reali a, b, c con a ≠ 0; il limite della funzione (am + b)/(am + c) con m che tende a infinito è 1.
• Dimostrazione: Si divida ogni termine per m, e si prenda (a + b/m)/(a + c/m). Se dividiamo un numero piccolo per una quantità straordinariamente grande, il quoziente tende a zero; così, sia numeratore che denominatore tendono ad a, e il loro quoziente tende a 1.
• Il teorema del confronto per le funzioni (o dei carabinieri): se una funzione è maggiorata e minorata da due funzioni che tendono allo stesso limite, allora anche la funzione in questione tenderà a tale limite.
• Dimostrazione: vedi articolo.
[modifica] La dimostrazione
L’idea principale di questa dimostrazione è trovare un limite alle somme parziali
\sum_{k=1}^m \frac{1}{k^2} = \frac{1}{1^2} + \frac{1}{2^2} + \cdots + \frac{1}{m^2}
tra due espressioni tendenti ciascuna a π2/6 (con m che tende a infinito). Le due espressioni sono derivate dalle identità che coinvolgono le funzioni di cosecante e di cotangente. Queste identità a loro volta sono derivate dalla formula di De Moivre dato il numero reale x compreso tra 0 e π/2, e n un intero positivo, con la formula di De Moivre abbiamo:
\frac{\cos (nx) + i \sin (nx)}{(\sin x)^n} = \frac{(\cos x + i\sin x)^n}{(\sin x)^n} = \left(\frac{\cos x + i \sin x}{\sin x}\right)^n = (\cot x + i)^n.
Dal teorema binomiale invece ricaviamo:
(\cot x + i)^n = {n \choose 0} \cot^n x + {n \choose 1} (\cot^{n-1} x)i + \cdots + {n \choose {n-1}} (\cot x)i^{n-1} + {n \choose n} i^n
= \left[ {n \choose 0} \cot^n x - {n \choose 2} \cot^{n-2} x \pm \cdots \right] \; + \; i\left[ {n \choose 1}
\cot^{n-1} x - {n \choose 3} \cot^{n-3} x \mp \cdots \right].
La combinazione delle due equazioni dà l’identità:
\frac{\sin (nx)}{(\sin x)^n} = \left[ {n \choose 1} \cot^{n-1} x - {n \choose 3} \cot^{n-3} x \mp \cdots
\right].
Definiamo ora n = 2m + 1, dove m è in naturale, e x = rπ/(2m + 1), (dove r = 1, 2, ..., m): come conseguenza, nx = rπ, e quindi sin(nx) = 0 per ogni valore di n. Portando questi valori all'interno dell'identità sopra esposta, otteniamo: 0 = {{2m+1} \choose 1} \cot^{2m} x - {{2m+1} \choose 3} \cot^{2m-2} x \mp \cdots + (-1)^m{{2m+1} \choose {2m+1}}.
Questa equazione tiene conto dei valori x = rπ/(2m + 1), dove r = 1, 2, ..., m. Questi valori di x sono numeri compresi tra 0 e π/2, e poiché la funzione cot^2(x) ha corrispondenza biunivoca nell’intervallo (0, π/2), ogni cot^2(x) = cot^2(rπ/(2m + 1)) ha un valore diverso per ciascun r = 1, 2, ..., m. Poiché però dalla suddetta equazione ciascuno di questi numeri diversi da m è la radice di un polinomio di grado m,
p(t) := {{2m+1} \choose 1}t^m - {{2m+1} \choose 3}t^{m-1} \mp \cdots + (-1)^m{{2m+1} \choose {2m+1}}.
questo vuol dire che ogni x = cot^2(rπ/(2m + 1)), per r = 1, 2, ..., m è precisamente radice per il polinomio p(t). È dunque possibile calcolare la somma delle radici direttamente esaminando i coefficienti. Inserendo l'identità trigonometrica csc^2 x = cot^2 x + 1, abbiamo:
\csc ^2 \left(\frac{\pi}{2m+1}\right) + \csc ^2 \left(\frac{2 \pi}{2m+1}\right) + \cdots + \csc ^2
\left(\frac{m \pi}{2m+1}\right)
= {{2m+1} \choose 3} / {{2m+1} \choose 1} + m = \frac{(2m)(2m+2)}{6}.
Ora, consideriamo la diseguaglianza cot2 x < 1/x2 < csc2 x. Se aggiungiamo queste diseguaglianze per ciascuno dei numeri x = rπ/(2m + 1) e se usiamo le due identità qui sopra, otteniamo \frac{(2m)(2m-1)}{6} < \left( \frac{2m+1}{\pi} \right) ^2 + \left( \frac{2m+1}{2 \pi} \right) ^2 + \cdots +
\left( \frac{2m+1}{m \pi} \right) ^2 < \frac{(2m)(2m+2)}{6}.
A questo punto, moltiplicando per (π/(2m + 1))2, si ha:
\frac{\pi ^2}{6}\left(\frac{2m}{2m+1}\right)\left(\frac{2m-1}{2m+1}\right) < \frac{1}{1^2} + \frac{1}{2^2} +
\cdots + \frac{1}{m^2} < \frac{\pi ^2}{6}\left(\frac{2m}{2m+1}\right)\left(\frac{2m+2}{2m+1}\right).
Per m divergente a infinito, i termini a sinistra e a destra convergono a π2/6, e abbiamo, dal teorema del confronto:
\zeta(2) =
\sum_{k=1}^\infin \frac{1}{k^2} =
\lim_{m \to \infty}\left(\frac{1}{1^2} + \frac{1}{2^2} + \cdots + \frac{1}{m^2}\right) = \frac{\pi ^2}{6}
E questo completa la dimostrazione. Q.E.D.
[modifica] Altra dimostrazione
Un'altra procedura per il calcolo di ζ(2), che fa uso di integrali, si trova qui.
[modifica] Generalizzazione
Con procedimenti molto simili a quelli che aveva usato per il caso s=2 Eulero riuscì a trovare la forma chiusa per la somma dell'inverso di qualsiasi potenza pari:
\zeta(4) = 1 + \frac{1}{2^4} + \frac{1}{3^4} + \frac{1}{4^4} + \cdots = \frac{\pi^4}{90}
\zeta(6) = 1 + \frac{1}{2^6} + \frac{1}{3^6} + \frac{1}{4^6} + \cdots = \frac{\pi^6}{945}
Più in generale:
\zeta(2k)= \frac{2^{2k-1}\pi^{2k}|B_{2k}|}{(2k)!}
Dove B_k sono i numeri di Bernoulli. Non è stato però compiuto alcun passo nella determinazione di una forma chiusa per i valori dispari di \zeta(s): solo recentemente è stato dimostrato che:\zeta(3) (chiamata costante di Apery) è un numero irrazionale.

Importance of Cyber Security Globally
We live in an incredible digitally connected world. We spend our half of the total daytime on social media, games, trading, online transaction and even much more. Every time we connect to the internet, our data is visible to hackers because we are ignoring basic security instructions. There are many reasons for cyber-attacks like inadequate technology, lack of security education, accessing insecure website and portals. In today's era when we are managing our 70% of the data over the internet, we should care about cyber security, whether it is commercial business or residential household.
Internet-based industry such as e-commerce, banking, traveling, insurance and cloud-based is giving high priority to the cyber security. However, companies also accept their safety does not reach to optimum level because they lack of proper security related education in their organization. According to ITRC (Identity Theft Resource Center) report, until July 2016, there were more than 522 data breaches. The report also states that data breach is now diversifying into different sectors such as federal agencies, healthcare, and telecom. Many popular companies such as Centene, Federal Bureau of Investigation, Seagate and Internal Revenue Service are the notable examples of data breach in the USA. Such data breaches cause loss of personal information like Name, Contact Number, Social Security Number and ID cards on a large scale. In 2016, the total cost of cybercrime reached to $450 billion globally. There are various types of cybercrime attacks used by cybercriminals for various purposes such as data breach, vulnerability and much more. The major cyber-attacks are.
1. Cyber Fraud
2. Malware Attacks
3. Social Engineering Attacks
4. Technical Attacks
5. Vulnerability Exploitation
6. Login Attacks
#1. Cyber Fraud Cyber fraud is a process where cybercriminal tries to steal your money, personal, property and financial information. There are different types of cyber fraud such as Phishing attacks, Spear Phishing attacks, unauthorized disclosure, and Whaling.
#2. Malware Attacks
in this type of attack, the malware comes from specific files such as .exe source and adware. The virus activates just after you open the file and in cases, malware file download on your PC without your authorized approval.
