Save and Load .bat game | <p>I'm making a text game written in bat, and the game has been done, (or more, a good part of it, such as the commands, and at the stage where you can play it); however, I want to add the power to save your game, and load it again.</p>
<p>I think one could do this by having the .bat file write the variables which need to be saved (such as the item variables); however, I don't know how to do this. Any help would be appreciated, thanks.</p>
<p>I should have said, I can make it load, by use of:</p>
<pre><code> for /f "delims=" %%x in (config.txt) do (set "%%x")
</code></pre>
<p>However, I don't know how to make the .bat write to the file and so "save".</p> | 0 |

Change hotkey for autocomplete selection | <p>In Eclipse, I find it pretty annoying that Enter is the hotkey that selects an item from the Content Assist/Autocomplete list. Especially in PyDev where there is no end-of-line semicolon, pressing enter for a new line will instead give me whatever is selected in the Autocomplete list.</p>
<p>Tab is a much better selection hotkey since I'm not likely to want a tab mid-line.</p>
<p>Any chance of changing this in Eclipse?</p>
<p>Using CDT, PDT, and PyDev, but interested in any solution related to Eclipse.</p> | 0 |

Iterating over arrays by reflection | <p>I am doing some reflection work and go to a little problem.</p>
<p>I am trying to print objects to some GUI tree and have problem detecting arrays in a generic way.</p>
<p>I suggested that :</p>
<blockquote>
<p>object instanceof Iterable</p>
</blockquote>
<p>Would make the job ,but it does not, (obviously applies only to Lists and Set and whoever implements it.)</p>
<p>So how is that i would recognice an Array Some <code>Object[]</code> , Or <code>long[]</code> or <code>Long[]</code> .. ?</p>

How can I generate a random number within a range in Rust? | <blockquote>
<p>Editor's note: This code example is from a version of Rust prior to 1.0 and is not syntactically valid Rust 1.0 code. Updated versions of this code produce different errors, but the answers still contain valuable information.</p>
</blockquote>
<p>I came across the following example of how to generate a random number using Rust, but it doesn't appear to work. The example doesn't show which version of Rust it applies to, so perhaps it is out-of-date, or perhaps I got something wrong.</p>
<pre><code>// http://static.rust-lang.org/doc/master/std/rand/trait.Rng.html
use std::rand;
use std::rand::Rng;
fn main() {
let mut rng = rand::task_rng();
let n: uint = rng.gen_range(0u, 10);
println!("{}", n);
let m: float = rng.gen_range(-40.0, 1.3e5);
println!("{}", m);
}
</code></pre>
<p>When I attempt to compile this, the following error results:</p>
<pre class="lang-none prettyprint-override"><code>test_rand002.rs:6:17: 6:39 error: type `@mut std::rand::IsaacRng` does not
implement any method in scope named `gen_range`
test_rand002.rs:6 let n: uint = rng.gen_range(0u, 10);
^~~~~~~~~~~~~~~~~~~~~~

test_rand002.rs:8 let m: float = rng.gen_range(-40.0, 1.3e5);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~
</code></pre>
<p>There is another example (as follows) on the same page (above) that does work. However, it doesn't do exactly what I want, although I could adapt it.</p>
<pre><code>use std::rand;
use std::rand::Rng;
fn main() {
let mut rng = rand::task_rng();
let x: uint = rng.gen();
println!("{}", x);
println!("{:?}", rng.gen::<(f64, bool)>());
}

JPA Updating Bidirectional Association | <p>Lets assume we have the following Entities: </p>
<pre><code> @Entity
public class Department {
@OneToMany(mappedBy="department")
private List<Employee> employees;
}
@Entity
public class Employee {
@ManyToOne
private Department department
}
</code></pre>
<p>It is understandable on an update that we need to maintain both sides of the relationship as follows:</p>
<pre><code>Employee emp = new Employee();
Department dep = new Department();
emp.setDepartment(dep);
dep.getEmployees().add(emp);
</code></pre>
<p>All good up till now. The question is should I apply merge on both sides as follows, and an I avoid the second merge with a cascade?</p>
<pre><code>entityManager.merge(emp);
entityManager.merge(dep);
</code></pre>
<p>Or is merging the owning side enough? Also should these merges happen inside a Transaction or EJB? Or doing it on a simple controller method with detached entities is enough?</p> | 0 |
Starting async method as Thread or as Task | <p>I'm new to <code>C#</code>s <code>await/async</code> and currently playing around a bit.</p>
<p>In my scenario I have a simple client-object which has a <code>WebRequest</code> property. The client should send periodically alive-messages over the <code>WebRequest</code>s <code>RequestStream</code>.
This is the constructor of the client-object:</p>
<pre><code>public Client()
{
_webRequest = WebRequest.Create("some url");
_webRequest.Method = "POST";
IsRunning = true;
// --> how to start the 'async' method (see below)
}
</code></pre>
<p>and the async alive-sender method</p>
<pre><code>private async void SendAliveMessageAsync()
{
const string keepAliveMessage = "{\"message\": {\"type\": \"keepalive\"}}";
var seconds = 0;
while (IsRunning)
{
if (seconds % 10 == 0)
{
await new StreamWriter(_webRequest.GetRequestStream()).WriteLineAsync(keepAliveMessage);
}
await Task.Delay(1000);
seconds++;
}
}
</code></pre>
<p>How should the method be started?</p>
<blockquote>
<p>new Thread(SendAliveMessageAsync).Start();</p>
</blockquote>
<p>or</p>
<blockquote>
<p>Task.Run(SendAliveMessageAsync); // changing the returning type to Task</p>
</blockquote>
<p>or</p>
<blockquote>
<p>await SendAliveMessageAsync(); // fails as of the constructor is not async</p>
</blockquote>
<p>My question is more about my personal understanding of <code>await/async</code> which I guess may be wrong in some points.</p>
<p>The third option is throwing</p>
<pre><code>The 'await' operator can only be used in a method or lambda marked with the 'async' modifier

How to sum up an array of integers in C# | <p>Is there a <strike>better</strike> shorter way than iterating over the array?</p>
<pre><code>int[] arr = new int[] { 1, 2, 3 };
int sum = 0;
for (int i = 0; i < arr.Length; i++)
{
sum += arr[i];
}
</code></pre>
<hr>
<p>clarification:</p>
<p>Better primary means cleaner code but hints on performance improvement are also welcome. (Like already mentioned: splitting large arrays).</p>
<hr>
<p>It's not like I was looking for killer performance improvement - I just wondered if this very kind of <strong>syntactic sugar</strong> wasn't already available: "There's String.Join - what the heck about int[]?".</p> | 0 |
HTML/CSS show/hide multiple elements? | <p>I'm looking for an HTML/CSS solution to this challenge:
I have multiple elements with the same class or same id, and I want to show/hide them all at the same time, using a button or toggle switch. So I then have a click event, when I click that class or ID representing all those elements, they all hide. When I click again, they must show again.</p>
<p>I would appreciate</p>

CMake Custom Command copy multiple files | <p>I am attempting to copy multiple files using the <code>${CMAKE_COMMAND} -E copy <from> <to></code> format, but I was wondering if there was a way to provide a number of files to copy to a specific directory. It seems the cmake copy only allows for one file to be copied at a time. I really don't want to use the copy command repeatedly when I would rather provide a list of files to copy as the first argument.</p>
<p>I'm thinking the easiest solution is to use the platform dependent "cp" command. While this definitely is not good for portability, our system is guaranteed to be built on Linux. A simple, platform independent solution would be better.</p> | 0 |

Reason for java.sql.SQLException "database in auto-commit mode" | <p>I use <code>sqlite</code> database and <code>java.sql</code> classes in servlet application to batch-insert some data into database.
There are consecutive four inserts of different kinds of data.
Each one looks like this:</p>
<pre><code>PreparedStatement statement = conn
.prepareStatement("insert or ignore into nodes(name,jid,available,reachable,responsive) values(?,?,?,?,?);");
for (NodeInfo n : nodes)
{
statement.setString(1, n.name);
statement.setString(2, n.jid);
statement.setBoolean(3, n.available);
statement.setBoolean(4, n.reachable);
statement.setBoolean(5, n.responsive);
statement.addBatch();
}
conn.setAutoCommit(false);
statement.executeBatch();
conn.commit();
conn.setAutoCommit(true);
statement.close();
</code></pre>
<p>But sometimes I get the </p>
<pre><code>java.sql.SQLException: database in auto-commit mode
</code></pre>
<p>I found in source code of <code>java.sql.Connection</code> that this exception is thrown when calling <code>commit()</code> while database is in autocommit mode. But I turn autocommit off before and I can't see any place for some parallel execution related issues as for now application is only turned on once. </p>
<p>Do you have any idea how to debug this issue? Maybe there's some other reason for this error (because I just found that exception about database not found or not well configured can be thrown when inserting <code>null</code> into non-null field)?.</p> | 0 |
select records from postgres where timestamp is in certain range | <p>I have arrival column of type timestamp in table reservations ( I'm using postgres ).
How would I select all dates within this year for example?</p>

</code></pre>
<p>But I've ran <strong>analyze</strong> and it looks like it require a sequence scan.
Is there a better option?</p>

SqlBulkCopy Insert with Identity Column | <p>I am using the <code>SqlBulkCopy</code> object to insert a couple million generated rows into a database. The only problem is that the table I am inserting to has an identity column. I have tried setting the <code>SqlBulkCopyOptions</code> to <code>SqlBulkCopyOptions.KeepIdentity</code> and setting the identity column to <code>0</code>'s, <code>DbNull.Value</code> and <code>null</code>. None of which have worked. I feel like I am missing something pretty simple, if someone could enlighten me that would be fantastic. Thanks!</p>
<p><em>edit</em> To clarify, I do not have the identity values set in the <code>DataTable</code> I am importing. I want them to be generated as part of the import.</p>

Here is the code I use to create the base <code>SqlBulkCopy</code> object.</p>

How to rewrite urls of images in vendor CSS files using Grunt | <p>I am trying to move frontend dependencies out of the version control system. A combination of Bower.io and Grunt should be able to do this.</p>
<p>A problem however occurs that I am yet unable to solve with bundling multiple vendor libraries. For example assume I have the following directory structure where the <em>components</em> directory is the directory that Bower.io saves the dependencies in:</p>
<pre><code>βββ assets
βββ components
βββ bootstrap
βΒ Β βββ img
βΒ Β βΒ Β βββ glyhs.gif
βΒ Β βββ less
βΒ Β βββ bootstrap.css
βββ jquery-ui
βββ css
βΒ Β βββ style.css
βββ images
βββ next.gif
βββ prev.gif
</code></pre>
<p>Now assume I want to bundle both jQuery's <strong>style.css</strong> and Bootstrap' <strong>bootstrap.css</strong>. I will save this bundled file in <strong>assets/bundled.css</strong>. </p>
<p>However in this file the references to the original images (../images/next.gif and ../img/glyhs.gif) are incorrect. They will have to be rewritten in order to work (so ../images/next.gif => ../components/jquery-ui/images/next.gif). I believe(d) this rewriting of URLs is something Grunt should be able to do. <strong>But I can not seem to get this to work using the cssmin/less/copy tasks</strong>. For example the following Grunt setup (only moving 1 file) fails to work:</p>
<pre><code>module.exports = function (grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
less: {
options: {
compile: false,
relativeUrls: true
},
bootstrap: {
src: 'components/bootstrap/less/bootstrap.less',
dest: 'assets/bootstrap.css'
}
}
});
grunt.loadNpmTasks('grunt-contrib-less');
grunt.registerTask('dist-css', ['less']);
};
</code></pre>
<p>Either:</p>
<ul>
<li><p>Have I misconfigured Grunt or done something wrong? </p></li>
<li><p>Or is the workflow I am describing simply not the right one and should I use another one instead.</p></li>
</ul>

BigInteger Conversion from int to BigInteger | <p>I'm having trouble working with BigIntegers. I'm having trouble with the <code>add</code> method in the Rational class. In the <code>Rational(int x, int y)</code> constructor I'm trying to convert the parameters datatype <code>int</code> into the instance variable datatype of <code>BigInteger</code> though the use of the<code>toString(int n)</code> method. <br/></p>
<ol>
<li>Am I doing the conversion correctly inside the <code>Rational(int x, int y)</code> constructor? </li>
<li>They way the <code>add</code> method is written I'm getting an error under all of n.num and n.den. I don't understand why I'm getting that error. Am I not correctly using the <code>add</code> method from the BigInteger class?

<br/><br/></li>
</ol>
<p>Suppose one class has the following</p>

Rational b = new Rational(1,3);
Rational c = new Rational(1,6);
Rational sum = a.add(b).add(c);

Valid characters for Excel sheet names | <p>In Java, we're using the following package to programmatically create excel documents:</p>
<pre><code>org.apache.poi.hssf
</code></pre>
<p>If you attempt to set a sheet's name (NOT file, but internal Excel sheet), you will get an error if:</p>
<ul>
<li>The name is over 31 characters</li>
<li>The name contains any of the following characters: / \ * ? [ ]</li>
</ul>
<p>However, after creating a document with a sheet name of:</p>
<blockquote class="spoiler">
<p>@#$%&()+~`"':;,.|</p>
</blockquote>
<p>No error is output, and everything seems fine in Java. When you open the excel file in Office 2003, it will give you an error saying that the sheet name was invalid and that it renamed it to something generic like "Sheet 1".</p>
<p>I don't know much about the previously stated package that we're using, but it looks like it's not correctly filtering invalid Excel sheet names. Any idea of how I can filter out all known invalid characters? I'm hesitant to simply filter out all non-word characters.</p> | 0 |

Running a java applet from netbeans? | <p>I am trying to run a Java applet from NetBeans, and in trying to run it, I get a 'main class not found' error. I can avoid this by doing SHIFT+F6, but that'll only work if I am currently writing in the main class. I will be working on a somewhat large project, and it's going to have multiple files, and eventually it will be quite cumbersome to always navigate back to the main class to the 'main' file and run it from there. Is there any sort of configurations I can edit to tell NetBeans that I want to run my project (not the individual file) as an applet?
I have NetBeans set up from <a href="http://blogs.oracle.com/pc/entry/how_to_create_applet_with" rel="noreferrer">this tutorial</a>.</p> | 0 |

Ruby File::directory? Issues | <p>I am quite new to ruby but enjoying it so far quite immensely. There are some things that have given me some trouble and the following is no exception.</p>
<p>What I am trying to do here is create a sort of 'super-directory' by sub-classing 'Dir'. I've added a method called 'subdirs' that is designed to list the directory object's files and push them into an array if the file is a directory itself. The issue is, the results from my test (File.directory?) is strange - here is my method code:</p>
<pre><code> def subdirs
subdirs = Array.new
self.each do |x|
puts "Evaluating file: #{x}"
if File.directory?(x)
puts "This file (#{x}) was considered a directory by File.directory?"
subdirs.push(x)
#yield(x) if block_given?
end
end
return subdirs
end
</code></pre>
<p>And strangely, even though there are plenty of directories in the directory I've chosen ("/tmp") - the result of this call only lists "." and ".."</p>
<pre><code>puts "Testing new Directory custom class: FileOps/DirClass"
nd = Directory.new("/tmp")
subs = nd.subdirs
</code></pre>
<p>And the results:</p>
<pre><code>Evaluating file: mapping-root
Evaluating file: orbit-jvxml
Evaluating file: custom-directory
Evaluating file: keyring-9x4JhZ
Evaluating file: orbit-root
Evaluating file: .
This file (.) was considered a directory by File.directory?

Why doesn't my <script> tag work from php file? (jQuery involved here too) | <p>Here is what I am trying to accomplish. I have a form that uses jQuery to make an AJAX call to a PHP file. The PHP file interacts with a database, and then creates the page content to return as the AJAX response; i.e. this page content is written to a new window in the success function for the <code>$.ajax</code> call. As part of the page content returned by the PHP file, I have a straightforward HTML script tag that has a JavaScript file. Specifically:</p>
<pre><code><script type="text/javascript" src="pageControl.js"></script>
</code></pre>
<p>This is not echoed in the php (although I have tried that), it is just html. The pageControl.js is in the same directory as my php file that generates the content.</p>
<p>No matter what I try, I can't seem to get the <code>pageControl.js</code> file included or working in the resulting new window created in response to success in the AJAX call. I end up with errors like "Object expected" or variable not defined, leading me to believe the file is not getting included. If I copy the JavaScript directly into the PHPfile, rather than using the script tag with src, I can get it working.</p>
<p>Is there something I am missing here about scope resolution between calling file, php, and the jQuery AJAX? I am going to want to include javascript files this way in the future and would like to understand what I am doing wrong.</p>
<hr>
<p>Hello again:</p>
<p>I have worked away at this issue, and still no luck. I am going to try and clarify what I am doing, and maybe that will bring something to mind. I am including some code as requested to help clarify things a bit.</p>
<p>Here is the sequence:</p>
<ol>
<li>User selects some options, and clicks submit button on form.</li>
<li><p>The form button click is handled by jQuery code that looks like this:</p>
<pre><code>$(document).ready(function() {
$("#runReport").click(function() {
var report = $("#report").val();
var program = $("#program").val();
var session = $("#session").val();
var students = $("#students").val();
var dataString = 'report=' +report+
'&program=' +program+
'&session=' +session+
'&students=' +students;
$.ajax({
type: "POST",
url: "process_report_request.php",
cache: false,
data: dataString,
success: function(pageContent) {
if (pageContent) {
$("#result_msg").addClass("successMsg")
.text("Report created.");
var windowFeatures = "width=800,menubar=yes,scrollbars=1,resizable=1,status=yes";
// open a new report window
var reportWindow = window.open("", "newReportWindow", windowFeatures);
// add the report data itself returned from the AJAX call
reportWindow.document.write(pageContent);
reportWindow.document.close();
}
else {
$("#result_msg").addClass("failedMsg")
.text("Report creation failed.");
}
}
}); // end ajax call
// return false from click function to prevent normal submit handling
return false;
}); // end click call
}); // end ready call
</code></pre></li>
</ol>
<p>This code performs an AJAX call to a PHP file (<code>process_report_request.php</code>) that creates the page content for the new window. This content is taken from a database and HTML. In the PHP file I want to include another javascript file in the head with javascript used in the new window. I am trying to include it as follows</p>
<pre><code><script src="/folder1/folder2/folder3/pageControl.js" type="text/javascript"></script>
</code></pre>
<p>Changed path folder names to protect the innocent :) </p>
<p>The pageControl.js file is actually in the same folder as the jQuery code file and the php file, but I am trying the full path just to be safe. <strong>I am also able to access the js file using the URL in the browser, and I can successfully include it in a static html test page using the script src tag.</strong></p>
<p>After the javascript file is included in the php file, I have a call to one of its functions as follows (echo from php):</p>
<pre><code> echo '<script type="text/javascript" language="javascript">writePageControls();</script>';
</code></pre>
<p>So, once the php file sends all the page content back to the AJAX call, then the new window is opened, and the returned content is written to it by the jQuery code above.</p>
<p><em>The <code>writePageControls</code> line is where I get the error "Error: Object expected" when I run the page.</em> However, since the JavaScript works fine in both the static HTML page and when included "inline" in the PHP file, it is leading me to think this is a path issue of some kind.</p>
<p>Again, no matter what I try, my calls to the functions in the pageControls.js file do not work. <strong><em>If I put the contents of the pageControl.js file in the php file between script tags and change nothing else, it works as expected.</em></strong></p>
<p>Based on what some of you have already said, I am wondering if the path resolution to the newly opened window is not correct. But I don't understand why because I am using the full path. Also to confuse matters even more, my linked stylesheet works just fine from the PHP file.</p>
<p>Apologies for how long this is, but if anyone has the time to look at this further, I would greatly appreciate it. I am stumped. <strong>I am a novice when it comes to a lot of this</strong>, so if there is just a better way to do this and avoid this problem, I am all ears (or eyes I suppose...)</p> | 0 |

How to get Property Value from MemberExpression without .Compile()? | <p>I'm having issues trying to get the value of an object out of the Expression Tree without using .Compile()</p>
<p>The object is quite simple.</p>
<pre><code>var userModel = new UserModel { Email = "[email protected]"};
</code></pre>
<p>The method giving me issues looks like this.</p>
<pre><code>private void VisitMemberAccess(MemberExpression expression, MemberExpression left)
{
var key = left != null ? left.Member.Name : expression.Member.Name;
if (expression.Expression.NodeType.ToString() == "Parameter")
{
// add the string key
_strings.Add(string.Format("[{0}]", key));
}
else
{
// add the string parameter
_strings.Add(string.Format("@{0}", key));
// Potential NullReferenceException
var val = (expression.Member as FieldInfo).GetValue((expression.Expression as ConstantExpression).Value);
// add parameter value
Parameters.Add("@" + key, val);
}
}
</code></pre>
<p>The tests I'm running are quite simple</p>
<pre><code>[Test] // PASS
public void ShouldVisitExpressionByGuidObject ()
{
// Setup
var id = new Guid( "CCAF57D9-88A4-4DCD-87C7-DB875E0D4E66" );
const string expectedString = "[Id] = @Id";
var expectedParameters = new Dictionary<string, object> { { "@Id", id } };
// Execute

var actualParameters = actualExpression.Parameters;
var actualString = actualExpression.WhereExpression;
// Test
Assert.AreEqual( expectedString, actualString );
CollectionAssert.AreEquivalent( expectedParameters, actualParameters );
}
</code></pre>
<pre><code>[Test] // FAIL [System.NullReferenceException : Object reference not set to an instance of an object.]

var actualParameters = actualExpression.Parameters;
var actualString = actualExpression.WhereExpression;
// Assert
Assert.AreEqual( expectedString, actualString );
CollectionAssert.AreEquivalent( expectedParameters, actualParameters );
}
</code></pre>
<hr>
<p>I should note that changing</p>
<pre><code>var val = (expression.Member as FieldInfo).GetValue((expression.Expression as ConstantExpression).Value);
</code></pre>
<p>to</p>
<pre><code>var val = Expression.Lambda( expression ).Compile().DynamicInvoke().ToString();
</code></pre>
<p>will allow the test to pass, however this code needs to run on iOS, and therefore can't use <code>.Compile()</code></p> | 0 |
What is session invalidation? | <p>Session invalidation means session destroying.So if session is destroyed,it indicates that server cant identify the client which has visited in previous.So now it creates a new session id for that client.</p>
<p>Is this right?If wrong tell me the correct procedure.</p> | 0 |
Mapping a SQL View with no Primary Key to JPA Entity | <p>In my Java App I want to get information that is stored in my Oracle Database, using JPA.
In my Database I have a View, with a set of columns that I got from some other tables. I want to map that View. However, my <strong>View doesn't have a Primary Key</strong>, so I can't create a JPA Entity. I thought about <strong>use 2 columns as Foreign Keys</strong>.</p>
<p>What's the best way of implementing that? I've seen so many different approaches, that I can't decide which is the best for this case.</p> | 0 |
how to dynamically add swt widgets to a composite? | <p>I'm trying to add widgets like text boxes, buttons to a composite on click of a button.
I've tried , but i could only add these widgets dynamically only up to the size of the composite. My jface dialog is such that, it has a scrolled composite in which it holds a composite. In the main composite i have 3 other composites where i have to achieve this
functionality, so if i add dynamic widgets to a composite it might expand, but it should not overlap existing composites down to it, rather it should adjust other composites accordingly and also i should be able to dispose those widgets on a button click. Did any one try this dynamic addition and removal of widgets before, I'm new to swt, jface . So, could any one share their experience here, I'm posting the code i've tried.</p>

FancyBox 'Uncaught TypeError: Cannot call method 'hide' of undefined' | <p>I've been screwing around with fancybox. I work in the CakePHP Framework and I made an admin panel. This panel has a few options which I load via AJAX into an Div over the page itself.</p>

<p>Now this is my ajax loader (functions.js) </p>

$("#admin_wrapper").fadeIn('slow');
$("#admin_content").fadeIn('slow');
$("#admin_close").fadeIn('slow');
$("#admin_content").html(data);
}
});
return false;
});
</code></pre>
<p>admin_content is where the images are displayed:</p>
<pre><code>#admin_content{
display:none;
position:absolute;
z-index:10;
background-color:#fff;

<p>But if I go to the page itself (without using ajax) it works perfectly fine.</p>
<p>Is there something that overrules fancybox? The error is not that clear to me.

GCC: why constant variables not placed in .rodata | <p>I've always believed that GCC would place a <code>static const</code> variable to <code>.rodata</code> segments (or to <code>.text</code> segments for optimizations) of an ELF or such file. But it seems not that case.</p>
<p>I'm currently using <code>gcc (GCC) 4.7.0 20120505 (prerelease)</code> on a laptop with GNU/Linux. And it does place a static constant variable to <code>.bss</code> segment:</p>
<pre><code>/*
* this is a.c, and in its generated asm file a.s, the following line gives:
* .comm a,4,4
* which would place variable a in .bss but not .rodata(or .text)
*/
static const int a;
int main()
{
int *p = (int*)&a;
*p = 0; /* since a is in .data, write access to that region */
/* won't trigger an exception */
return 0;
}
</code></pre>
<p>So, is this a bug or a feature? I've decided to file this as a bug to bugzilla but it might be better to ask for help first.</p>
<p>Are there any reasons that GCC can't place a const variable in <code>.rodata</code>?</p>
<p><strong>UPDATED:</strong></p>
<p>As tested, a constant variable with an explicit initialization(like <code>const int a = 0;</code>) would be placed into <code>.rodata</code> by GCC, while I left the variable uninitialized. Thus this question might be closed later -- I didn't present a correct question maybe.</p>
<p>Also, in my previous words I wrote that the variable a is placed in '.data' section, which is incorrect. It's actually placed into <code>.bss</code> section since not initialized. Text above now is corrected.</p> | 0 |

Downloading Xcode with wget or curl | <p>I am trying to download Xcode from the Apple Developer site using just wget or curl. I think I am successfully storing the cookie I need to download the .dmg file, but I am not completely sure.</p>
<p>When I run this command:</p>
<pre><code>wget \
--post-data="theAccountName=USERNAME&theAccountPW=PASSWORD" \
--cookies=on \
--keep-session-cookies \
--save-cookies=cookies.txt \
-O - \
https://developer.apple.com/ios/download.action?path=/ios/ios_sdk_4.1__final/xcode_3.2.4_and_ios_sdk_4.1.dmg > /dev/null
</code></pre>
<p>A file called <code>cookies.txt</code> is created and contains something like this:</p>
<pre><code>developer.apple.com FALSE / FALSE 0 XXXXXXXXXXXXXXXX XXXXXXXXXXXX
developer.apple.com FALSE / FALSE 0 developer.sessionToken
</code></pre>
<p>I'm not completely certain, but I think there should be more to it than that (specifically, an alphanumeric string after <code>sessionToken</code>).</p>
<p>When I try to do the same thing with curl using this:</p>
<pre><code>curl \
-d "theAccountName=USERNAME&theAccountPW=PASSWORD" \
-c xcode-cookie \
-A "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1" \
https://developer.apple.com/ios/download.action?path=/ios/ios_sdk_4.1__final/xcode_3.2.4_and_ios_sdk_4.1.dmg
</code></pre>
<p>I get a file called <code>xcode-cookie</code> that contains the same information as the <code>cookies.txt</code> file wget gives me, except that the lines are reversed.</p>
<p>I then tried to download the .dmg file.</p>
<p>Using wget:</p>
<pre><code>wget \
--cookies=on \
--load-cookies=cookies.txt \
--keep-session-cookies \
http://developer.apple.com/ios/download.action?path=/ios/ios_sdk_4.1__final/xcode_3.2.4_and_ios_sdk_4.1.dmg
</code></pre>
<p>This gives me a file called <code>login?appIdKey=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX&path=%2F%2Fios%2Fdownload.action?path=%2Fios%2Fios_sdk_4.1__final%2Fxcode_3.2.4_and_ios_sdk_4.1.dmg
</code>, which is just an HTML page containing the login form for the developer site.</p>
<p>Using curl:</p>
<pre><code>curl \
-b xcode-cookie \
-c xcode-cookie \
-O -v \
-A "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1" \
https://developer.apple.com/ios/download.action?path=/ios/ios_sdk_4.1__final/xcode_3.2.4_and_ios_sdk_4.1.dmg
</code></pre>
<p>Which prints basically the same thing as wget (minus the HTML).</p>
<p>I want to say it has to do with the sessionToken not being in the cookie, but like I said before I am not sure. I even tried exporting the cookies from my browser and following the instructions in the blog post I linked below and several other sites I found while searching for help.</p>
<p>I must be doing something wrong, unless Apple has changed something since Oct. 10 <a href="http://greendesignhq.com/blog/2010/10/downloading-xcode-builds-with-wget-or-curl/" rel="noreferrer">because this guy seems to be to do something right</a>.</p>

How to sort alphabetically rows of a data frame? | <p>I am tring to sort <code>c</code> alphabetically <code>if x[i]== x[i+1]</code>. I used <code>order()</code> function but it changes the <code>x</code> column as well. I want to order the entire row:</p>
<pre><code> best <- function(state){
HospitalName<-vector()
StateName<-vector()
HeartAttack<-vector()
k<-1
outcome<-read.csv("outcome-of-care-measures.csv",colClasses= "character")
temp<-(outcome[,c(2,7,11,17,23)])
for (i in 1:nrow(temp)){
if(identical(state,temp[i,2])==TRUE){
HospitalName[k]<-temp[i,1]
StateName[k]<-temp[i,2]
HeartAttack[k]<-as.numeric(temp[i,4])
k<-k+1
}}
frame<-data.frame(cbind(HospitalName,StateName,HeartAttack))
library(dplyr)
frame %>%
group_by(as.numeric(as.character(frame[,3]))) %>%
arrange(frame[,1])
}
Output:
HospitalName StateName HeartAttack
1 FORT DUNCAN MEDICAL CENTER TX 8.1
2 TOMBALL REGIONAL MEDICAL CENTER TX 8.5
3 CYPRESS FAIRBANKS MEDICAL CENTER TX 8.7
4 DETAR HOSPITAL NAVARRO TX 8.7
5 METHODIST HOSPITAL,THE TX 8.8
6 MISSION REGIONAL MEDICAL CENTER TX 8.8

9 THE HEART HOSPITAL BAYLOR PLANO TX 9
10 UT SOUTHWESTERN UNIVERSITY HOSPITAL TX 9

<p>Output does not contain the HeartAttack Column and I do not understand why?</p> | 0 |
Bootstrap 3 full width div's in container-fluid | <p>I'm trying to create some "horizontal bands" in a Bootstrap 3 CSS layout, extending to the whole size of the browser's window, and thus outside of the content class margins. Here is a Plunker: <a href="http://plnkr.co/edit/6SlNU0ZgFehrBD64r9FG" rel="nofollow">http://plnkr.co/edit/6SlNU0ZgFehrBD64r9FG</a> . I found that I can accomplish this by using a <code>container-fluid</code> class: this implies having a div with that class including other div's, some representing my "bands", and others just using the <code>container</code> class. Thus, my relevant CSS is:</p>
<pre><code>div.band {
width: 100% !important;
background-color: #D7EAD8;
color: #323F3F;
}
</code></pre>
<p>and my HTML:</p>
<pre><code><div class="container-fluid">
<div class="row band">Hello band</div>
<div class="container">
<div class="row">...</div>
</div>
<div class="row band">Another band</div>
<div class="container">
<div class="row">...</div>
</div>
</div>
</code></pre>
<p>Yet, this does not fully work as I keep getting some white margin at the right edge of the "band" div. I don't know Bootstrap internals and surely I'm doing something wrong, could anyone suggest a solution to make the "band" full-width?</p> | 0 |

Validate in merge function pandas | <p>Today I was trying to go a little deeper in the <code>merge()</code> function of pandas, and I found the option <code>validate</code>, which, as reported in the documentation, can be:</p>
<blockquote>
<p>validate : string, default None</p>
<p>If specified, checks if merge is of specified type.</p>
<p>βone_to_oneβ or β1:1β: check if merge keys are unique in both left and
right datasets. βone_to_manyβ or β1:mβ: check if merge keys are unique
in left dataset. βmany_to_oneβ or βm:1β: check if merge keys are
unique in right dataset. "many_to_manyβ or βm:mβ: allowed, but does
not result in checks.</p>
</blockquote>
<p>I have looked around to find a working example on where and how to use this function, but I couldn't find any. Moreover when I tried to apply it to a group of <code>DataFrame</code>'s I was merging, it didn't seem to change the output.

Preview layout with merge root tag in Intellij IDEA/Android Studio | <p>Let's imagine we are developing compound component based on LinearLayout. So, we create class like this:</p>
<pre><code>public class SomeView extends LinearLayout {
public SomeView(Context context, AttributeSet attrs) {
super(context, attrs);
setOrientation(LinearLayout.VERTICAL);
View.inflate(context, R.layout.somelayout, this);
}
}
</code></pre>
<p>If we'll use <code>LinearLayout</code> as a root of <code>somelayout.xml</code>, we'll have extra view level, so we use merge tag:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Some text"
android:textSize="20sp"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Some other text"/>
</merge>
</code></pre>
<p>But in Preview tab in IDE merge always acts as FrameLayout, and we'll see something like that:
<img src="https://i.stack.imgur.com/V9wpb.png" alt="Preview with merge"></p>
<p>(It is Android Studio, Intellij IDEA is just the same, about Eclipse I don't know)</p>
<p>Preview speed up developing layouts a lot, it's sad lose such a great help even for some layouts. May be there is a way to specify, how Preview should interpret <code>merge</code> tag in particular layout?</p> | 0 |

<a href="https://stackoverflow.com/questions/496096/casting-vs-using-the-as-keyword-in-the-clr">Casting vs using the βasβ keyword in the CLR</a> </p>

<p>I recently learned about a different way to cast. Rather than using</p>
<pre><code>SomeClass someObject = (SomeClass) obj;
</code></pre>
<p>one can use this syntax:</p>
<pre><code>SomeClass someObject = obj as SomeClass;
</code></pre>
<p>which seems to return null if obj isn't a SomeClass, rather than throwing a class cast exception.</p>
<p>I see that this can lead to a NullReferenceException if the cast failed and I try to access the someObject variable. So I'm wondering what's the rationale behind this method? Why should one use this way of casting rather than the (old) one - it only seems to move the problem of a failed cast "deeper" into the code.</p> | 0 |

<p>Therefore, what would your top 1 blog be in each of these technologies and which technology do you find easiest to stay up to date with? I'd have a bias towards blogs with broad and high level rather than narrow and detailed content / solutions / examples.</p> | 0 |
How to set MySQL to use GMT in Windows and Linux | <p>I'm just trying to get MySQL to store time in GMT...</p>
<p>I've read the documentation here: <a href="http://dev.mysql.com/doc/refman/5.1/en/time-zone-support.html" rel="noreferrer">http://dev.mysql.com/doc/refman/5.1/en/time-zone-support.html</a></p>
<p>It says to set: default-time-zone='timezone' in an option file.</p>
<p>However, I've googled for several different terms and cannot find possible values "timezone" is supposed to be. I also don't know where in my.ini (and in Linux, my.cnf) to put this directive. Below [msyqld] ?</p> | 0 |
Should I Always Fully Qualify Column Names In SQL? | <p>Out of interest when working with SQL statements should I always use the fully qualifed column name (tablename.columnname) even if only working with one table e.g.</p>

pause/resume a python script in middle | <p>Can I have a running python script(under Windows)being paused in the middle by user , and resume again when user decides ? </p>
<p>There is a main manager program which generates,loads and runs other python scripts (by calling python script.py from console).I don't have GUI and user can interact via console.I want my main program be able to respond to user pause/resume command for the running script.Should I define a thread? Whats the approach ?</p>
<p>Edit/Update :</p>
<p>Let's say I have a small python application with frontend which has various functions. I have a RUN command which runs python scripts in background .I want to implement a PAUSE feature which would pause the running python script . When the user commands RUN again then the python script should resume
running .
using raw_input() or print() forces user to issue command.But in this case, we don't know when user want to interrupt/pause/issue a command.So usual input/print is not usable.</p> | 0 |
Mocking service in a component - mock ignored | <p>This time I'm trying to mock a service (that does http calls) to test a component.</p>
<pre><code>@Component({
selector: 'ub-funding-plan',
templateUrl: './funding-plan.component.html',
styleUrls: ['./funding-plan.component.css'],
providers: [FundingPlanService]
})
export class FundingPlanComponent implements OnInit {
constructor(private fundingPlanService: FundingPlanService) {
}
ngOnInit() {
this.reloadFundingPlans();
}
reloadFundingPlans() {
this.fundingPlanService.getFundingPlans().subscribe((fundingPlans: FundingPlan[]) => {
this.fundingPlans = fundingPlans;
}, (error) => {
console.log(error);
});
}
}
</code></pre>
<p>The <a href="https://angular.io/docs/ts/latest/guide/testing.html#!#component-with-dependency" rel="noreferrer">documentation</a> (version 2.0.0) explains that you should mock the service. Using the same <code>TestBed</code> configuration:</p>
<pre><code>describe('Component: FundingPlan', () => {
class FundingPlanServiceMock {
getFundingPlans(): Observable<FundingPlan> { return Observable.of(testFundingPlans) }
}
beforeEach(() => {
TestBed.configureTestingModule({
declarations: [FundingPlanComponent],
providers: [
{ provide: FundingPlanService, useClass: FundingPlanServiceMock },
]
});
fixture = TestBed.createComponent(FundingPlanComponent);
component = fixture.componentInstance;
});
fit('should display a title', () => {
fixture.detectChanges();
expect(titleElement.nativeElement.textContent).toContain('Funding Plans');
});
});
</code></pre>
<p>When I run the test, I get:</p>
<pre><code>Error: No provider for AuthHttp!
</code></pre>
<p>that is indeedused by the actual service, but not by the mock. So for some reason, the mock is not injected or used.</p>
<p>Any advise? Thanks!</p> | 0 |
c# How to retrieve Json data into an array | <p>I have found different libraries that can parse Json data, but i did not find any documentation on how to get the data into an C# array or list.</p>
<p>I got this Json data:</p>
<p>{"001":{"Name":"John", "Phone":["Mob - 98837374","Mob - 98363627"]},
"002":{"Name":"Tom", "Phone":["Mob - 49858857"]}}</p>
<p>Anybody got a clue? :)</p>
<p><strong>Edit</strong>:</p>
<p><em>Useful details posted by OP as comments re-posted as question edit by AnthonyWJones</em></p>

List<string> entities = (List<string>)JsonConvert.DeserializeObject(responseFromServer, typeof(List<string>));
foreach (string items in entities) {

jQuery Accordion - Need index of currently selected content part | <p>I have a simple menu on a web page, based on the jQuery Accordion. I have simplified the code somewhat, and it looks like this;</p>
<pre><code><div id="menu_div" class="nt-tab-outer nt-width-150px">
<h3 class="nt-tab-title"><a href="#">Menu A</a></h3>
<div id="menu_1_div">
<a href="itemA1">Item A1</a><br />
<a href="itemA2">Item A2</a><br />
</div>
<h3 class="nt-tab-title"><a href="#">Menu B</a></h3>
<div id="menu_2_div">
<a href="fTabsDyn">Item B1</a><br />
<a href="fPlainDyn">Item B2</a><br />
</div>
</div>
<script type="text/javascript">
jQuery(function() {
jQuery("#menu_div").accordion({
active: 1,
change: function(event, ui) {
alert('bob');
}})
});
</script>
</code></pre>
<p>This sets the 2nd "part" of the accordion open when the page opens. (active:1) and if either of the headers is clicked a simple alert "bob" pops up. So far so good.</p>
<p>Now I'd like to replace "bob" with the index of the header. So the "read" version of "active". ie, when the first accordion header is clicked I get 0, and if the second header is clicked I get a 1.</p>
<p>(Aside, of course I don't really want to do an Alert, I want to make an Ajax call to the server with the value, so the server knows which menu is open at the client. That part I can do, but I'm struggling to get the right value to send. If the index is not available then feel free to offer alternate suggestions).</p>
<p>Thanks!</p> | 0 |

Facebook Graph API get all likes from a post | <p>I am very new to facebook graph api, actually I just started today so I might use some help.</p>
<p>My code is working perfectly, I've written a simple algorithm to list people who like a certain post, but the problem is this. Here is the JSON reply I get from graph api:</p>
<pre><code><br/>
{<br/>
"likes": {<br/>
"data": [<br/>
{<br/>
"name": "NAME",<br/>
"id": "ID"<br/>
},<br/>
{<br/>
"name": "NAME",<br/>
"id": "ID"<br/>
},<br/>
{<br/>
"name": "NAME",<br/>
"id": "ID"<br/>
},<br/>
{<br/>
"name": "NAME",<br/>
"id": "ID"<br/>
}<br/>
],<br/>
"count": 22<br/>
},<br/>
"id": "POST ID",<br/>
"created_time": "DATE CREATED"<br/>
}<br/>
</code></pre>
<p>so even though there are COUNT:22 Likes, the server returns only 4 names. Is it possible to get all the names? if so, how?</p> | 0 |
Objective-C UILabel as HyperLink | <p>I am trying to make a <code>UILabel</code> a link for a <code>UIWebView</code>. How can I make a <code>UILabel</code> to work as hyperlink?</p> | 0 |
VBA Excel - Compile Error Object Required | <p><strong>Disclosure: I'm fairly inexperienced at coding of most sorts but have a reasonable understanding of the logic behind it and quite often just need a little push with getting syntax's right etc.</strong></p>
<p><strong>I posted the same code earlier but with a different problem and have no discovered this issue so I thought it best to create a new question for it</strong></p>
<p><strong>Objective:</strong> What I'm trying to do is create a spreadsheet where across the top row is a list of consecutive dates. In the first few columns is data for bills etc. What I want my macro to do is look at the amount of a bill, the start and end dates and the frequency of the bill (weekly/monthly etc) and then populate the cells in that same row in the columns of the dates where the bill is due. I've spent the last day coming up with this code and I was pretty happy with it until I went to run it. I've already got rid of a few bugs where I was using a variable.Value which apparently doesn't exist and I had messed up the syntax for Cells(row, column).</p>
<p>The problem that I'm coming up against now is Compile Error: Object Required on this line: </p>
<pre><code>Set dateAddress = Range("J1:AAI1").Find(currentDate, LookIn:=xlValues).Address
'find the current date within the range of dates in row 1
</code></pre>
<p>What that line is supposed to be doing is searching across all the dates in the first row for that 'currentDate' and then storing that as dateAddress so that I can then use the dateAddress.Column in the next line of code along with the currentRow, to find the right cell that is to be populated with the bill amount.</p>
<p>Am I being clear enough? My code is below.</p>
<p>My Code: </p>
<pre><code>Private Sub CommandButton1_Click()
Dim currentDate As Date
Dim currentRow As Integer
Dim repeatuntilDate As Date
Dim repeatuntilRow As Integer
Dim dateAddress As Date
currentRow = 3 'First row of entries
repeatuntilRow = Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row 'Last row of entries
While currentRow < repeatuntilRow 'Loop from first row until last row of entries
currentDate = Cells(currentRow, "G").Value 'Set Start Date
repeatuntilDate = Cells(currentRow, "H").Value 'Set End Date
While currentDate <= repeatuntilDate 'Loop from Start Date until End Date
Set dateAddress = Range("J1:AAI1").Find(currentDate, LookIn:=xlValues).Address 'find the current date within the range of dates in row 1
Cells("dateAddress.Column,currentRow").Value = Cells("D,currentRow").Value 'Populate cell with amount
'Increment the currentDate by the chosen frequency
If Cells(currentRow, "E").Value = "Weekly" Then
currentDate = DateAdd("ww", 1, currentDate)
ElseIf Cells(currentRow, "E").Value = "Fortnightly" Then
currentDate = DateAdd("ww", 2, currentDate)
ElseIf Cells(currentRow, "E").Value = "Monthly" Then
currentDate = DateAdd("m", 1, currentDate)
ElseIf Cells(currentRow, "E").Value = "Quarterly" Then
currentDate = DateAdd("q", 1, currentDatee)
ElseIf Cells(currentRow, "E").Value = "6 Monthly" Then
currentDate = DateAdd("m", 6, currentDate)
ElseIf Cells(currentRow, "E").Value = "Annually" Then
currentDate = DateAdd("y", 1, currentDate)
' ElseIf Cells(currentRow,"E").Value = "Once off" Then
' Exit While
End If
Wend
currentRow = currentRow + 1 'Once row is complete, increment to next row down
Wend
End Sub

JavaScript access string chars as array | <p>Is it ok to do this:</p>
<pre><code>var myString="Hello!";
alert(myString[0]); // shows "H" in an alert window
</code></pre>
<p>Or should it be done with either charAt(0) or substr(0,1)?
By "is it ok" I mean will it work on most browsers, is there a best practice recommandation that says otherwise etc.</p>

How to change a button's size | <pre><code>int width, height;
width = this.Size.Width;
height = this.Size.Height;
width /= 3;
height /= 3;
btn_1.Size = new Size(width, height);
</code></pre>
<p>I am trying to make a button's size and location change when the user resizes a form.</p>
<p>How can I assigning a size to a button?</p>
<p>I tried to make it with changing width and height separately. I know that I can make it by anchoring it, but I would like to make it with pure coding.<br>
Also refreshing the form did not work. I can set the locations of buttons easily with the <code>Location</code> property, but the size property does not work. I couldn't find the difference...</p>
<p>Here is the full code which works for changing the positions of objects, but does not work for changing the size:</p>
<pre><code>private void form_counterMain_Resize(object sender, EventArgs e)
{
int width, height;
Point templocation;
templocation = new Point(0, 0);
width = this.Size.Width;
height = this.Size.Height;
width /= 3;
height /= 3;
//:::location:::
btn_1.Location = templocation;
templocation.X = width;
btn_2.Location = templocation;
templocation.X = width * 2;
btn_3.Location = templocation;
templocation.X = 0;
templocation.Y = height;
btn_4.Location = templocation;
templocation.X = width;
btn_5.Location = templocation;
templocation.X = width * 2;
btn_6.Location = templocation;
templocation.Y = height * 2;
templocation.X = 0;
btn_7.Location = templocation;
templocation.X = width;

Java - JPA - @Version annotation | <p>How does <code>@Version</code> annotation work in JPA?</p>
<p>I found various answers whose extract is as follows:</p>
<blockquote>
<p>JPA uses a version field in your entities to detect concurrent modifications to the same datastore record. When the JPA runtime detects an attempt to concurrently modify the same record, it throws an exception to the transaction attempting to commit last.</p>
</blockquote>
<p>But I am still not sure how it works.</p>
<hr>
<p>Also as from the following lines:</p>
<blockquote>
<p>You should consider version fields immutable. Changing the field value has undefined results. </p>
</blockquote>
<p>Does it mean that we should declare our version field as <code>final</code>?</p> | 0 |
