3,528,443 | 3,528,444 | Why is a special file used in Android to store installation id instead of SharedPreferences? | <p>I am trying to figure out the best way to store my application key and other application specific data. Android uses a file to do it - <a href="http://android-developers.blogspot.com/2011/03/identifying-app-installations.html" rel="nofollow">http://android-developers.blogspot.com/2011/03/identifying-app-installations.html</a></p>
<p>I found that using SharedPreferences is faster and more efficient. Why does Android use a dedicated file just to store the installation ID instead of using preferences? Both require the application context, so that is not a reason.</p>

3,568,520 | 3,568,521 | Storing all JS/CSS in PHP? | <p><strong>Background:</strong> I'm working on a single page web app that loads everything through AJAX and so started learning php a few days ago. I immediately thought of putting everything (html, css, javascript) in php files so that there is only one html file and one sprite request. For instance, external javascript could be stored in:</p>
<p><strong>main.js.php</strong> (adding the .js for organizational purposes only) which would look like:</p>
<pre><code><script>
...
</script>
</code></pre>
<p>or</p>
<pre><code><style>
...
</style>
</code></pre>
<p><strong>Question:</strong> Would storing everything in php be a bad idea? I have OCD and like to have related functions in separate files (and actually, folders too), so let's just say my project uses 100+ includes. These only get loaded exactly once, when the user visits (AJAX site). I want to reduce the number of Http Requests to just 1 html and 1 sprite (my app uses a custom font for images actually). My app will also be ran on mobile devices (using a different design, using far fewer includes but a similar method).</p>
<p><strong>Research:</strong> Here's what I know:</p>
<ul>
<li>You can have Apache handle js/css as php, but is not something I'm interested in (dangerous) - <a href="http://stackoverflow.com/questions/984148">link</a></li>
<li>This site gave me the idea, although I don't quite understand it - <a href="http://www.catswhocode.com/blog/3-ways-to-compress-css-files-using-php" rel="nofollow">3 Ways to Compress CSS</a></li>
<li>Caching with something like APC (not sure how it works, but out of the scope of this question) would improve php speeds (?)</li>
</ul>

143,150 | 143,151 | value of ASP.NET variables for different users | <p>I'm using VS2010,C# to develop my ASP.NET web app, sometimes I need to declare public or even public static variable at start of my codebehind files, so that I can access them globally in the file and also they preserve their value between postbacks, everything works fine on my local server (as I'm the only person who runs the code). But I don't know exactly what happens when this page (and therefor its codebehind) are run by several web site visitors at the same time, I want my program to run the same for all users, but I think in this way something will cause problems, I can remember from my previous ASP.NET experience that using variable (public or public static) in codebehind can cause misunderstanding for different users of web site, for instance:
user A runs program, (public static int) my_int that had the value of -1 at startup has taken value of 100, and at this time user B runs the same page, so my_int is 100 and it will cause problems, also suppose that user A leaves the page while my_int has value of 100, then user B will visit the page my_int would be initially 100 (while that should be -1) so I think unexpected behaviors would occur</p>
<p>is it right? will this happen at all? if so, how can I prevent it? should I use session instead of variables? how can I have a better understanding about the whole situation</p>

26,206 | 26,207 | Mysterious javascript behaviour: unequal equals | <p>I really don't know how is it possible, and I couldn't reproduce the error in a simplified environment, say JSFiddle. But here is how it looks in my application. </p>
<p>I'm trying to convert value that can be 'True', 'False' or 'something else' string into boolean if it is either True or False. In most cases it works just fine (although they may be a slicker way of doing the conversion) as it is shown on the picture below</p>
<p><img src="http://i.stack.imgur.com/8yVbg.png" alt="enter image description here"></p>
<p>however on occasion it fails and the value of the watch shows as follow:</p>
<p><img src="http://i.stack.imgur.com/DBgIZ.png" alt="enter image description here"></p>
<p>So suddenly string variable with a value of "True" is not equal to a "True" string literal. I'm lost. How is it possible? What am I missing here? </p>
<p>Thanks in advance</p>

635,132 | 635,133 | Why can't I return only in a nested body of my Method and not be forced to return in the scope of the main method? | <p>Why is it that if you declare a return type on a method, that you have to specify a return in the scope of that method? Meaning, if I have a If/Switch in my method I can't specify the return there "ALONE" and not in the main method body? Is the only way around this is to assign the value returned by the nested procedure to a variable and return the variable in the main body of the method?</p>
<p>Example:</p>
<pre><code>public Int GetNum()
{
var a = 1;
switch(a)
{
case 1:
return 1 + 5;
default:
return a;
}
return a; //Why must I specify this return if it is going to hit my switch statement
//and return some int.
}

344,021 | 344,022 | Why Can You Instantiate a Class within its Definition? | <p>A coworker (who is very new to Java) stopped in today and asked what seemed like a very simple question. Unfortunately, I did an absolutely horrible job of trying to explain it to him. He had a book that had a little code that looked like this:</p>
<pre><code>class XCopy {
public static void main(String[] args) {
XCopy x = new XCopy(); // 1
x.doIt();
}
public void doIt() {
// Some code...
}
}
</code></pre>
<p>He was confused on line 1. What he wanted to know was why a new instance of XCopy could be created within the definition of the class XCopy. He thought this would have given some sort of a forward referencing error. After all, we hadn't yet finished declaring what the class XCopy was, so how could we create one?</p>
<p>I certainly know that this is valid code but, when I tried to explain it to him, I found myself stumbling over the answer and I'm afraid I left him more confused than when he started. I'd like to hear some other explanations of why this works.</p>
<p>Any thoughts? Why can you instantiate an instance of a class within the definition of the class, itself?</p>

329,130 | 329,131 | Can't get custom scrollbar jquery plugin (tiny scrollbar) to work on another gallery plugin (galleria) | <p>Been at this for a while. Trying to add a custom scroll bar to the photo gallery (customized Jquery galleria plugin) on expression engine, but no matter what I do it doesn't seem to work.</p>
<p>The site is live at www.pleasuredoingbusiness.org, and it's the collections page that i'm having trouble with. Galleria works fine, and i've modified the tinyscrollbarcolgal.js file so that it creates the appropriate divs/classes for tiny scroll bar. But it doesn't load up the javascript for some reason</p>
<p>galleria creates .galleria-container which is what i'm targeting with the tiny scrollbar plugin.</p>
<p>I've tried to load the custom scrollbar with $(window).load instead of $(document).ready, which got it to finally show up, but only if you refresh the page. (on chrome) On IE it still just doesn't show up at all</p>
<p>I've also tested with another custom scrollbar plugin and got the same results. Doesn't show unless i do $(window).load instead of $(document).ready, but only works if you refresh it. I've actually thought of maybe forcing it to refresh/load just once, couldn't get that to work (it kept looping), and the refresh thing doesn't seem to work on ie either.</p>
<p>Can anyone help!!?? Thanks in advance.</p>

for (var day in data){
console.log('On day' + day + ' , ' + id + ' has a value of ' data[day].id)
