table[1] = [3, 23, 99, 43, 2];
table[2] = [1, 1, 0, 43, 67];

<pre><code>var table = new Array(3)
table[0] = [45, 4, 34, 99, 56];
table[1] = [3, 23, 99, 43, 2];
table[2] = [1, 1, 0 43, 67]

<p>If, as in the tutorial, <code>var table</code> is initially declared as an array with 5 elements, and then the first (table[0]), second (table[1]) and third (table[2]) are filled with the data, what happens with the other two elements that were initially set in the array with new Array(5).

<p><strong>Edit</strong>: To answer the comments asking what and why:</p>
<p>I'm setting up a Stack Exchange site and the WMD* js file loads halfway down the page. SE will allow you to insert HTML in various parts of the page - so you can have your custom header and footer etc. I want to override the standard WMD code with my own version of it.
I can get around the problem by just loading javascript after the original WMD script loads and replacing the functions with my own - but it would be nice not to have such a large chunk of JS load needlessly.</p>

<p>The code below attempts to set the browser to fullscreen, sometimes it works, sometimes not. It ALWAYS calls the alert to indicate it is requesting fullscreen. Here's what I've found:</p>
<ul>
<li>It USUALLY sets fullscreen. It can get to a state where this stops working, but the alert still happens, i.e. it is still requesting FullScreen, but it doesn't work.</li>
<li>It can work if called from a keypress handler (document.onkeypress), but not when called on page loading (window.onload).</li>
</ul>
<p>My code is as follows:</p>
<pre><code>function DoFullScreen() {
var isInFullScreen = (document.fullScreenElement && document.fullScreenElement !== null) || // alternative standard method
(document.mozFullScreen || document.webkitIsFullScreen);
var docElm = document.documentElement;
if (!isInFullScreen) {
if (docElm.requestFullscreen) {
docElm.requestFullscreen();
}
else if (docElm.mozRequestFullScreen) {
docElm.mozRequestFullScreen();
alert("Mozilla entering fullscreen!");
}
else if (docElm.webkitRequestFullScreen) {
docElm.webkitRequestFullScreen();
alert("Webkit entering fullscreen!");
}
}

<p>I was guessing that may be because there are other dialogs already opened that's why another form (the main page) can't open the expiring dialog, but it still doesn't show up when I made the other dialogs non-modal. I am using IE 8 with jQuery 1.4.2 min , 1.8.2 UI, and 1.2.0 layout libs. </p>
<p>I have a main page which opens other dialogs / small windows too, so if the session expires while any of them are opened then the expiring dialog don't show up, and IE 8 pops a warning message at the top telling "compatibility view". Is there a way to tell jQuery to allow the expiring dialog to show up no matter what or at what level it pops up?</p>

I ask about <code>best practices</code> because the JavaScript is always visible for the user and therefore it is not possible to prevent cheating completly, I just want to make it harder.]</em></p>
<p>I'm developing a JavaScript based game that works in the browser. I want to make a high score list that contains the user name and the score of all users. To achieve that the browser sends , after the user finished the game, the user name and the score to my server (via AJAX) that handles everything for the high scores.</p>
<p>To submit fake scores to this list would be fairly easy: One could take a look at the AJAX requests and then make an own AJAX request with a faked score. To use something like a <code>token</code> that has to be send with the other data is pointless, as it will be easy to discover.</p>
<p>My only approach, that would prevent cheating, would be to send a description of every user action to the server and calculate the score there. But this is not really practicable as it would be too much for the server.</p>
<p><strong>I accepted an answer, but in case anyone has other ideas about how to make cheating harder, please create another answer!</strong></p>

1,543,337 | 1,543,338 | Does an Intent's extras still get flattened into a Parcel even if the new activity is being started within the same task? | <p>I was wondering...</p>
<p>So if you start a new activity via an intent, the intent has to be serialized and deserialized because you may have to send the intent to a separate VM instance via IPC. But what if the PackageManager <em>knows</em> that your new activity will be created on the current task? It seems like a reasonably Googly optimization would be not to serialize the intent at all, since it's all happening inside the same VM. But then again, you can't just allow the new activity to use the same instance of each parcelable, because any changes made by the new activity would show up in the old activity and the programmer might not be expecting this.</p>
<p>So, is this optimization being done? Or do the extras always get marshalled and unmarshalled, no matter what?</p>

1342502700
I found that I get the sum in seconds between UTC and local standard time via:
>>> time.timezone / 3600
8
So If I add 1342502700 to time.timezone:
>>> print 1342502700 + time.timezone
1344153600
</code></pre>
<p>Will it always give me PDT / PST times correctly? </p>
<p>EDIT::</p>
<p>Maybe this is the correct one:</p>
<pre><code>>>> import time
>>> offset = time.timezone if (time.daylight == 0) else time.altzone
>>> offset / 60 / 60
7
</code></pre>
<p>time.daylight will be non-zero if daylight savings is currently in effect.</p>

</blockquote>
<p>I'm working on an assignment for my C++ class and I was hoping I could get some help. One of my biggest problems in coding with C++ is parsing strings. I have found longer more complicated ways to parse strings but I have a very simple program I need to write which only needs to parse a string into 2 sections: a command and a data section. For instance: <code>Insert 25</code> which will split it into Insert and 25. </p>
<p>I was planning on using an array of strings to store the data since I know that it will only split the string into 2 sections. However I also need to be able to read in strings that require no parsing such as <code>Quit</code> </p>
<p>What is the simplest way to accomplish this without using an outside library such as boost? </p>

97,720 | 97,721 | EditText hint not displaying | <p>Being new to Android Development <code>(c# OOP dev 10+)</code> I ran into a slight snag (2.3.3) I don't know how to address. I have an <code><EditText.../></code> that has two parameters that cancel each other out. </p>
<p>What I mean is that as an Android user I really appreciate when people use tags such as android:inputType="numberDecimal" for an input field where they expect numbers. This saves me from
having to flip from ABC to 123 keyboard while trying to complete a field. However the problem comes in when trying to use the <code>android:hint="Hint Text"</code>. The hint text won't display if the field has been determined to be a numeric as defined by the <code>android:inputtype</code>. </p>
<p>So I was looking for input on how best to resolve this problem. My thoughts are have a label above the input field...this would standout as the rest of the app uses hint's. I could forgo a hint but not really a good idea as the user would be lost as to what info goes in the field. My third and best thought is to define the inputtype as text then handle the onFocus event and switch it to numeric.</p>
<p>Any other suggestions welcome.

The question asks whether it's better to have a well-commented fancy piece of code or a self-commented (i.e. no comments) longer version.</p>
<p>The problem with my example was that the fancy version turned out to be more understandable than the non-fancy version. Since I can't think of any good examples, I figure I'd try asking here. So what I need is two examples of C++ code which produce the exact same result, but in one version the code is short but very complicated and cannot be understood immediately without having to think about it, and a longer but much more readable and understandable version.</p>
<p>I want someone to look at the fancy version and go "Shit, that's complicated. I'm glad it's commented, otherwise I wouldn't have understood what it does" and then look at the longer version and go "Ah, I understand what it does, even without comments". The shorter example should be something like 1-10 lines and the longer maybe 10-30 lines.</p>
