Efficient way to convert a list to dictionary
|
<p>I need help in the most efficient way to convert the following list into a dictionary: </p>
<pre><code>l = ['A:1','B:2','C:3','D:4']
</code></pre>
<p>At present, I do the following:</p>
<pre><code>mydict = {}
for e in l:
k,v = e.split(':')
mydict[k] = v
</code></pre>
<p>However, I believe there should be a more efficient way to achieve the same. Any idea ?</p>

Find next lower item in a sorted list
|
<p>let's say I have a sorted list of Floats. Now I'd like to get the index of the next lower item of a given value. The usual for-loop aprroach has a complexity of O(n). Since the list is sorted there must be a way to get the index with O(log n).</p>
<p>My O(n) approach:</p>
<pre><code>index=0
for i,value in enumerate(mylist):
if value>compareValue:
index=i-1
</code></pre>
<p>Is there a datatype for solving that problem in O(log n)?</p>

How do I get the module instance for a class in Python?
|
<p>I am learning Python, and as always, I'm being ambitious with my starter projects. I am working on a plugin system for a community site toolkit for App Engine. My plugin superclass has a method called <code>install_path</code>. I would like to obtain the <code>__path__</code> for the <code>__module__</code> for <code>self</code> (which in this case will be the subclass). Problem is, <code>__module__</code> returns a <code>str</code> rather than the module instance itself. <code>eval()</code> is unreliable and undesirable, so I need a good way of getting my hands on the actual module instance that doesn't involve <code>eval</code>ling the <code>str</code> I get back from <code>__module__</code>.</p>

Learning classes but having an odd issue that I am sure is simple
|
<p>So I am learning how to use classes and python and I am creating a simple program to perform arithmetic operations with rational numbers. I am creating a class called ArithmeticOperations. In this class I have a main function definition which prompts the user for the numerator and denominator of 2 rational numbers, then performs either the sum, difference, product, or quotient based on the choice of the user. The operations are performed in a separate function. Right now I have created the main function and the product function, but when I run it I get an error that says </p>
<blockquote>
<p>TypeError: product() takes exactly 5 arguments (6 given)</p>
</blockquote>
<p>I am sure this is something simple but I am new to classes so i am having a bit of trouble debugging. Here is my current program:</p>
<pre><code>class ArithmeticOperations:
# Given numbers u0, v0, and side, design a pattern:
def product(self,n1, d1, n2,d2):
self.numerator = n1*n2;
self.denominator = d1*d2;
print n1,'/',d1,'*',n2,'/',d2,'=',self.numerator,'/',self.denominator;
def main(self):
n1 = input('Enter the numerator of Fraction 1: ');
d1 = input('Enter the denominator of Fraction 1: ');
n2 = input('Enter the numerator of Fraction 2: ');
d2 = input('Enter the denominator of Fraction 2: ');
print '1: Add \n 2: Subtract\n 3: Multiply\n 4: Divide' ;
question = input('Choose an operation: ');
if question == 1:
operation = self.sum(self,n1,d1,n2,d2);
elif question == 2:
operation = self.difference(self,n1,d1,n2,d2);
elif question == 3:
operation = self.product(self,n1,d1,n2,d2);
elif question == 4:
operation = self.quotient(self,n1,d1,n2,d2);
else:
print 'Invalid choice'
ao = ArithmeticOperations();
ao.main();

How to minimize compilation time in C++
|
<p>I've coded an script that generates a header file with constants like version, svn tag, build number. Then, I have a class that creates a string with this information.</p>
<p>My problem is the following: As the file is created in every compilation, the compiler detects that the header has changed, and forces the recompilation of a large number of files. I guess that the problem is in the situation of the header file. My project is a library and header has to be in the "interface to the world" header file (it must to be public).</p>
<p>I need some advice to minimize this compilation time or to reduce the files forced to recompile.</p>

Should you make private properties?
|
<pre><code>private string mWhatever;
private string Whatever
{
get
{
return this.mWhatever;
}
set
{
this.mWhatever = value;
}
}
</code></pre>
<p>I've seen some people who make properties for every single member, private or not... does this make any sense? I could see it making sense in 1% of the cases at times when you want to control access to the member inside the class containing it because if you didn't use properties for every member it would lead to inconsistencies and checking to see if the member has an access or not (since you have access to both in the scope of the class).</p>

<p>It takes as input 3 ArrayLists of bigrams and compares them. If the second word from the first array list matches the word from the second array list then they create a sentence.</p>

2nd Array List: ate two
3rd Array List: two apples

<p>creates a sentence he ate two apples. But this function is only limited to 3 ArrayLists.

Can somebody help me with that?</p>

Rounding up with pennies in Python?
|
<p>I am making a change program in python. The user must input a dollar amount and then the program will calculate the change in twenties, tens, fives, ones, quarters, dimes, nickels, and pennies. I was instructed to use the round function for the pennies because If I input an amount of $58.79, the program tells me to give 3 pennies back when it should be 4. Is there a way to round up these pennies?</p>
<p>I know the value of a penny is .01, but python reads this as .100000000001 which I believe is the problem. </p>
<p>Any help is appreciated, here is the section I need rounded:</p>
<pre><code># get the amount to change from the user
change = input("Please enter the amount to change: $")
print "To make change for $",change,"give the customer back:"
# calculate number of twenties
twenties = int(change/ 20)
print twenties, "twenties"
change = change - twenties *20
# calculate tens
tens = int(change / 10)
print tens, "tens"
change = change - tens *10
#calculate fives
fives = int(change / 5)
print fives, "fives"
change = change - fives *5
#calculate ones
ones = int(change / 1)
print ones, "ones"
change = change - ones * 1
#calculate quarters
quarters = int(change / .25)
print quarters, "quarters"
change = change - quarters * .25
#calculate dimes
dimes = int(change / .10)
print dimes, "dimes"
change = change - dimes * .10
#calculate nickels
nickels = int(change / .05)
print nickels, "nickels"
change = change - nickels * .05
#calculate pennies
pennies = int(change / .01)
print pennies, "pennies"

Difference between int and numbers.Integral in Python
|
<p>I'm trying to get a deeper understanding in Python's data model and I don't fully understand the following code:</p>
<pre><code>>>> x = 1
>>> isinstance(x,int)
True
>>> isinstance(x,numbers.Integral)
True
>>> inspect.getmro(int)
(<type 'int'>, <type 'object'>)
>>> inspect.getmro(numbers.Integral)
(<class 'numbers.Integral'>, <class 'numbers.Rational'>, <class 'numbers.Real'>,
<class 'numbers.Complex'>, <class 'numbers.Number'>, <type 'object'>)
</code></pre>
<p>Based on the above, it seems that <code>int</code> and <code>number.Integral</code> are not in the same hierarchy.</p>
<p>From the Python reference (2.6.6) I see</p>
<blockquote>
<p>numbers.Integral - These represent elements from the mathematical set of integers (positive and negative).</p>
</blockquote>
<p>What's the difference between <code>int</code> and <code>numbers.Integral</code>? Does it have something to do with the <code>type int</code> vs <code>class numbers.Integral</code> I see in the above output?</p>

Storing GUI text as a ResourceBundle (no localization)?
|
<p>I would like to extract out the labels, error messages, button text etc from out the java code. There is too much discrepancy right now and changing things is a pain.</p>
<p>There are too many of these Strings to be implemented as constants in a java file. Ideally I would like it be something like a properties file.</p>
<p>Should I be using the ResourceBundle? This application is strictly English and will be in English for its life.</p>

Connection to ODBC in very restricted environment (sort of challenge)
|
<p>I usually type too much, so <strong>read bold copy if in a hurry</strong>.</p>
<p>I'm trying to develop a little app in a very restrictive environment (at work)... I want to read data from a database, but I cant install stuff on my machine (so my usual choice of using python or visual studio is a no-no). Basically I will have to do with whatever I've got at hand...</p>
<p><strong>What solution can you come up with to access an odbc connection and read the records of a table in an environment where you can't install any software?</strong> feel free to suggest any language, as long as you don't need to install anything.</p>
<p>My best idea so far is trying to use the web-browser (since i only need notepad to code), so... basically using only HTML and javascript to try to access it (although I have no clue how to acomplish that task, as I've never done it before)...</p>
<p>I know it is not a good idea, but since I won't post this on internet (I only I would have access to this from my desk, and the DB is on my local network), I don't think security is an issue.</p>
<p>Even if I don't get a solution, I would like to hear what would you guys try if the need arose. But any ideas or links pointing me in the right direction would be appreciated.</p>
<p>Edit: For clarity's sake, it is a Windows environment.</p>

Read from internal storage file (Android)
|
<p>How to read the particular data from the internal storage file.
For eg., I have stored
1. Device 2. Time(epoch format) 3. button text</p>
<pre><code> CharSequence cs =((Button) v).getText();
t = System.currentTimeMillis()/1000;
s = cs.toString();
buf = (t+"\n").getBytes();
buf1 = (s+"\n").getBytes();
try {
FileOutputStream fos = openFileOutput(Filename, Context.MODE_APPEND);
fos.write("DVD".getBytes());
fos.write(tab.getBytes());
fos.write(buf);
fos.write(tab.getBytes());
fos.write(buf1);
//fos.write(tab.getBytes());
//fos.write((R.id.bSix+"\n").getBytes());
fos.write(newline.getBytes());
//fos.flush();
fos.close();
} catch (FileNotFoundException e) {

How to remember to use return value?
|
<p>Sometimes I forget to use the return value when I <strong>have</strong> to. For example</p>
<pre><code>var s = "foobar";
s.Replace("foo", "notfoo");
// correct: s = s.Replace("foo", "notfoo");
</code></pre>
<p>This also applies to my custom value-like classes, for example, where I use fluent x.WithSomething() methods that return new value object instead of modifying x.</p>
<p>One solution would be to use unit tests. However, this is not always applicable. So, how do I force a compiler - or, at least, runtime - error when returned value is not used?</p>
<p>Maybe, there's a ReSharper or VS solution?</p>
<p>UPDATE: OK it is not enforced by language. So null arguments are, but still I can throw exception if argument is null. And ReSharper can warn me about many things that are not enforced by C#. But I see no way to do the same for not-used return value - for those return values that I want to be used.</p>
<p>If not for system functions (like string.Replace), but at least for my own classes - is there any way? Like, returning RequiredReturn<T> or something like this.</p>
<p>UPDATE: what about AOP / PostSharp? If I mark return value or method with [UsageRequired], can I detect somehow using PostSharp that return value was used?</p>
<p>(note the C# tag)</p>

//wheel.onload = initialDraw; // Once the image is loaded from file this function is called to draw the image in its starting position.
wheel.src = "./female_avatar.gif";

surfaceContext.drawImage(wheel, 0, 0);
p += .02;
var r = 100;
var xcenter = 150;
var ycenter = 150;
var newLeft = Math.floor(xcenter + (r* Math.cos(p)));
var newTop = Math.floor(ycenter + (r * Math.sin(p)));
var newLeft1 = Math.floor(xcenter + -(r* Math.cos(p)));
var newTop1 = Math.floor(ycenter + -(r * Math.sin(p)));

How can I split text on commas not within double quotes, while keeping the quotes?
|
<p>So I'm trying to split a string in javacript, something that looks like this:</p>
<pre><code>"foo","super,foo"
</code></pre>
<p>Now, if I use <code>.split(",")</code> it will turn the string into an array containing <code>[0]"foo" [1]"super [2]foo"</code>
however, I only want to split a comma that is between quotes, and if I use <code>.split('","')</code>, it will turn into <code>[0]"foo [1]super,foo"</code></p>
<p>Is there a way I can split an element expressing delimiters, but have it keep certain delimiters WITHOUT having to write code to concatenate a value back onto the string? </p>
<p>EDIT:</p>
<p>I'm looking to get <code>[0]"foo",[1]"super,foo"</code> as my result. Essentially, the way I need to edit certain data, I need what is in [0] to never get changed, but the contents of [1] will get changed depending on what it contains. It will get concatenated back to look like <code>"foo", "I WAS CHANGED"</code> or it will indeed stay the same if the contents of [1] where not something that required a change</p>

Execute script only for newly added HTML
|
<p>i am creating this mini-module framework and what i'm trying to do is to reuse a module definition on a dynamically loaded HTML. it's like using the same weather widget script to power two or more weather widgets on screen, one loaded on page load, and the others loaded later. defining the module uses this format.</p>
<pre><code>framework.module.create('module_name',function(){
//execute when starting the module
this.init = function(){
//for example, bind a click handler
$('button').on('click',function(){
alert('foo');
});
}
});
</code></pre>
<p>the module name and constructor is stored in an array and during page load, executed like</p>
<pre><code>//store
function create(name,fn){
modules[name] = fn;
}
//execute
function start(){
//for each module definition stored
var module = new modules[name]();
module.init();
}
</code></pre>
<p>now event handlers are bound to the elements. this works when the module html is already on the page. however, if i try loading another copy of that module's HTML which doesn't have handlers yet, calling <code>start()</code> binds it the handlers, but now doubles the handler for the existing/already initialized HTML. clicking the button on the preloaded HTML now fires click events twice.</p>
<p>i can't do this magic on the module definition. i need to preserve the "constructor/callback function" format. also, i don't want users to do workarounds for this. this has to be done under the framework code.</p>
<p>how do i execute the module script only for the newly added, exactly identical HTML?</p>
<p>or</p>
<p>how do i prevent the script from affecting the already initialized HTML?</p>

user input determines count of displays
|
<p>I have been trying for days to get this to work. I have the basic code but every time I try to get the last requirement added, I break the code. I'm sure I am missing a lot and that's why I can't add the alert box with the count of displays. So it asks the users name, the number of times they want to see and alert box and if they enter invalid answers they see alert boxes telling them to enter a correct value. The last part that I am stuck on is the value the user enters determines how many alert boxes show their name and the box needs to say which box it is. So, <code><Name></code> this is time number <code><count of displays></code> of <code><total time to display></code>. I was trying different things with limiting and FOR , with the user Y variable being the limiter. Any clues or help would be greatly appreciated.</p>
<pre><code><!DOCTYPE html>
<html>
<body>
<p>Please enter your name followed by how many times you would like to be alerted.</p>
<button onclick="myFunction()">Start</button>
<script>
function myFunction() {
var x;
var name = prompt("Please enter your name", "");
if (name == null || name == "") {
alert("Please input a name.");
return false;
}
else {
var y;
var y = prompt("Please enter a number between 1-10");
if (y == null || y == "") {
alert("Please input a number for the times to alert the name.");
return false;
}
if (y > 10) {
alert("Please input a number between 1 and 10.")
var y = prompt("Please enter a number between 1-10");
}
if (y <= 0) {
alert("Please input a number great than zero.")
var y = prompt("Please enter a number between 1-10");
}
}
}
</script>

jQuery Show One Div and Hide the Others
|
<p><a href="http://jsfiddle.net/yrM3H/2/" rel="nofollow">http://jsfiddle.net/yrM3H/2/</a></p>
<p>I have the following code:</p>
<pre><code>jQuery(document).ready(function() {
jQuery(".toggle").next(".hidden").hide();
jQuery(".toggle").click(function()
{
$('.active').toggleClass('active').next('.hidden').slideToggle(300);
$(this).toggleClass('active').next().slideToggle("fast");
});
});
</code></pre>
<p>I have multiple <code><div></code>'s, and my idea is that when I open a <code><div></code> it toggles another <code><div></code>. And then, when I click another <code><div></code>, it hides the open <code><div></code>. Therefore only one <code><div></code> is open at a time.</p>
<p>My only issue is that with this code, when I try to close a <code><div></code> that is already open, it will close and then open again. Thus one <code><div></code> will always be open.</p>
<p>Any help will be appreciated, thank you.</p>
<p>I added the HTML and CSS below. Everything works fine, except that I cannot get it so that all of them are closed.</p>
<p>I have 5 of these stacked on each other in a wrapper.</p>
<p>*edited for clarity *</p>
<pre><code>// HTML
<div class="toggle"></div>
<div class="hidden"></div>
// CSS
.toggle {width:398px; height:48px; cursor: pointer;}
.hidden {width:300px; height:75px; background-color:#333333; margin-left:50px; text-indent:25px;}

Can I create a server php variable?
|
<p>I want to have my own variable that would be (most likely an array) storing what my php application is up to right now.</p>
<p>The application can trigger few processes that are in background (like downloading files) and I want to have a list what is being currently processed. </p>
<p>For example </p>
<ul>
<li>if php calls exec() that will be downloading for 15mins </li>
<li>and then another download starts</li>
<li>and another download starts </li>
</ul>
<p>then if I access my application I want to be able to see that <code>3 downloads</code> are in process. If none of them finished yet.</p>
<p>Can do that? Only in memory, not storing anything on the disk?</p>
<p>I thought that the solution would be a some kind of server variable.</p>

MVC Framework that is similar to ASP.NET MVC but for Winform
|
<p>I know there are MVC for Winform (MVC# etc.) but if have to develop on ASP.NET MVC and then on Desktop I don't want to have 2 different frameworks so is there anything close to ASP.NET MVC but for Winform ?</p>
<p>What I mean is that the specific part of ASP.NET which is url routing for example should be replaced by something on winform so that one can readily switch from one platform to the other.</p>
<p>This seems rather common sense needs to me so why doesn't this seem to exist or taken into account at Microsoft ? </p>
<p>All focus seems to be on web development nowadays which I regret because there are many desktop apps in enterprise that have the same level of complexity as web app and would benefit from not reinventing the wheel and use a widely spread MVC framework.</p>

Using && for conditionals in Javascript
|
<p>I have this:</p>
<pre><code>var field = query("form#"+form.id+" input[name='" + error.field + "']");
if(field.length){
if( field[0].id ) {
widget = registry.byId( field[0].id );
if(widget){
...
}
}
</code></pre>
<p>I would have thought I could write:</p>
<pre><code>var field = query("form#"+form.id+" input[name='" + error.field + "']");
if(field.length && field[0].id && widget = registry.byId( field[0].id) ){
...
}
</code></pre>
<p>But if I use the second, "shortened" form, I get a Javascript error. </p>
<p>Sorry, it would be messy to give a JSFiddle. The problem happens when query() returns 0 values -- <code>field[0].id</code> && <code>widget = registry.byId( field[0].id)</code> were still interpreted.</p>
<p>I thought that I was playing it safe as the second <code>field[0].id</code> would only happen if <code>field.length</code> was <code>> 0</code> and then <code>widget = registry.byId( field[0].id)</code> would only happen if <code>field[0].id</code> is true...</p>
<p>What am I missing?</p>

How does PHP work - literature
|
<p>I'm interested in literature (articles on internet, in magazines, books, podcasts - I don't really mind anything) that describes how PHP works internally, about its gotchas and perhaps some advanced functions. Is there anything like this out there? I tried to search on Google, but majority of articles were about starting with PHP and its basic functions.</p>
<p>Any input is really welcome as I'm trying to understand the language internally - I'm tired of my mindless typing of code without understanding its essence.</p>

php script that populates photos to a html div

<p>I currently have a picture page with about 250 jpeg. Images and I currently have a web page where I manually assigned a picture to a section on the page, however this is very time consuming and would like to create a script that will run through and assign the images to a div. While this normally would be easy my problem is the way they filed the images. On the web page I have a quad drawling, and each portion of the quad needs a image assigned to it. the image file names vary and is causing my headache:</p>
<p>The file format Ex is below. so each quad would have 4 images, the first set of numbers before the underscore is the pict id and the number in between the underscores is which section of the quad the pict goes to. But the pict id vary in length and I’m not sure how to go about this. Any thoughts or recommendations are appreciated.</p>

|
<p>I've the following code:</p>
<pre><code>if ($type == 'unit'){
$item_title = $result["title"];
}
elseif ($type == 'message'){
$item_title = $result["description"];
}
// all should combine unit and message
elseif ($type == 'all'){
$item_title = $result["description"]
$item_title .= $result["title"];
}
if (stripos( $item_title, $filter ) !== false || stripos( $item_title, $filter ) !== false)
</code></pre>
