4,966,591 | 4,966,592 | Will strtok(null) cause any bugs? | <p>PHP script to read in user action requests and parse them to their components. Example, user types in <code>SET Colour = Blue</code> or <code>describe Chocolate Cake = The best cake ever!</code> I'm using like this:</p>
<pre><code>$actionKeyword = strtok( $actionRequest, " " ); // keyword followed by space
$name = strtok( "=" ); // Then name followed by equals
$description = strtok(null); // get the rest of the string
</code></pre>
<p>I could not find anything on getting the rest of the string. PHP.net's example was using spaces to tokenize each word but there was no character I could think of that might not be part of the description. This solution works in my tests.</p>
<p>Is there a side effect or special case this would fail on? Or is this a perfectly safe and acceptable way of getting the rest of the line?</p>

4,701,390 | 4,701,391 | Passing a variable through to another PHP page | <p>I'm making a server manager. I want to add a "kill" command, which would call a php script that would essentially run a shell_exec('kill $arrtext'); and kill the process, thus closing the server down. Here is the part of my script that returns the results and checks to see which servers are running:</p>
<pre><code><?php
$COMMAND = shell_exec('ps -o command ax | grep skulltag | grep -v grep');
$old = array("skulltag-server", "-port", "-iwad", "-wad", "+exec");
$new = array("SKULLTAG", "Running on Port", "Using IWAD", "+ PWAD", "with Config");
$COMMAND = str_replace($old, $new, $COMMAND);
$arr = explode("./",$COMMAND);
$text = shell_exec('pgrep -u doom');
$arrtext = preg_split('/\s+/', $text);
for( $i = 1; $i < count($arr); $i++ ) {
echo '<div class = "serverborder">';
echo '<div class = "servertextalign">';
echo $i,'. PROCESS ID <span style="color: #f00;">',$arrtext[$i],'</span> with server parameters: <span style="color: #777;">',$arr[$i],'</span>';
echo '</div>';
echo '</div>';
echo '<br>';
}
?>
</code></pre>
<p>However, I have no idea how I would add a link or something that would set the proper $arrtext[] variable (depending on which one they picked) and pass it to the PHP script that would kill the server.</p>

4,458,299 | 4,458,300 | Why does Firebug say toFixed() is not a function? | <p>I am using jQuery 1.7.2 and jQuery UI 1.9.1. I am using the code below within a slider. (http://jqueryui.com/slider/)</p>
<p>I have a function that should test two values and depending on the difference between the two values reformat them (to the appropriate decimal place). If the difference is greater than 10, I will parse out the integer. If the difference is greater than 5, it should keep one decimal. Everything else, I will keep two decimals. </p>
<p>When I enter two values that have a difference that is ten or less, I use the toFixed() function. And, in Firebug, I see an error:</p>
<pre><code>TypeError: Low.toFixed is not a function
Low = Low.toFixed(2);
</code></pre>
<p>Is there something simple that I am doing wrong? </p>
<p>Here is my code:</p>

High = $SliderValTo.val();
// THE NUMBER IS VALID
if (isNaN(Low) == false && isNaN(High) == false) {
Diff = High - Low;
if (Diff > 10) {
Low = parseInt(Low);
High = parseInt(High);

3,350,803 | 3,350,804 | TextView.onDraw causing endless loop | <p>I want a TextView which adjusts the font size so that the text in the view will automatically expand (or shrink) to fill the full width of the view. I thought I might be able to do this by creating a customised TextView which overrides onDraw() as follows:</p>
<pre><code>public class MaximisedTextView extends TextView {
// (calls to super constructors here...)
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
TextPaint textPaint = this.getPaint();
Rect bounds = new Rect();
String text = (String)this.getText(); // current text in view
float textSize = this.getTextSize(); // current font size
int viewWidth = this.getWidth() - this.getPaddingLeft() - this.getPaddingRight();
textPaint.getTextBounds(text, 0, text.length(), bounds);
int textWidth = bounds.width();
// reset font size to make text fill full width of this view
this.setTextSize(textSize * viewWidth/textWidth);
}
}
</code></pre>
<p>However, this sends the app into an endless loop (with the text size growing and shrinking slightly each time!), so I'm clearly going about it the wrong way. Does the call to setTextSize() trigger an invalidate so that onDraw is called again, endlessly?</p>
<p>Is there a way I can prevent the recursive call (if that's what is happening)? Or should I be going about it a completely different way?</p>

<pre><code>$.post("php/getSettings.php",

....................
$element.addClass('cl-Colour1');
// Second alert
alert($('.cl-Colour1').css('background-color'));

</code></pre>
<p>The above code was intended to make use of the classes created in the earlier block of codes.</p>
<p>However, I found that in the first alert, I see value = "138.43.226" which is correct (ie, it corresponds to the color code I have set). But in the second alert, I get a value of "0,0,0".</p>
<p>It appears that the classes in the first block of codes is not visible in the dialog page.</p>
<p>The next thing I did, I added the following into the CSS file:</p>
<pre><code>.cl-Colour1 {
background-color: #FE2EC8;
}
</code></pre>
<p>With this, the second alert will show "254,46,200" which seems to be the color defined in the CSS file.</p>
<p>So, how do I solve this problem?
In a nutshell, basically I want to define a set of classes of colors when the app loads and then make them available when I open a dialog.</p>

<p>I have an .each() loop that changes the value of sz[1] and fires a .load() for each value. However, when I place sz[1] in the callback function, it only uses the last recorded value of sz[1], and not the value it had when I initially called .load().</p>

5,559,097 | 5,559,098 | - (IBAction)doSomething:(id)sender model used generically | <p>So I was curious about something and not sure if there is a "standard" or "good" coding practice for something. If you have a home page for example with 3 buttons (like the facebook iphone app dashboard), that go to various parts of the app by pushing a view controller, then on one button, I would have the IBAction tied to it as:</p>
<pre><code>- (IBAction)showSummary:(id)sender {
SummaryViewController *detailViewController = [[[SummaryViewController alloc] initWithNibName:@"SummaryViewController" bundle:nil] autorelease];
detailViewController.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
detailViewController.view.autoresizesSubviews = YES;
[self.navigationController pushViewController:detailViewController animated:YES];
}
</code></pre>
<p>So my first question is, let's say on the first time I launch the app, I want to show this page first. So in viewDidLoad, could I just call this method</p>
<pre><code>[self showSummary:nil];
</code></pre>
<p>Or is it better to just have the same code in my viewDidLoad.</p>
<p>The second question regarding this is refactoring. If all 3 of my buttons do the same thing in creating a viewController and pushing it onto the stack, the only difference being which viewController to initializer </p>
<p>e.g.</p>
<pre><code>SummaryViewController *detailViewController = [[[SummaryViewController alloc]
</code></pre>
<p>Should I refactor these methods? If so, what would be a good way to do it? Thanks!</p>

<p>Even when the ViewStateEncryptionMode is not specified, the __VIEWSTATE hidden filed seem to be having encrypted values.</p>
<p>Assuming this is based on the default value ViewStateEncryptionMode.Auto, I set the page's ViewStateEncryptionMode to Never. Still I see the same value (in encrypted form) in the hidden field.</p>
<p>Is ViewStateEncryptionMode is dealing with something else than, the __viewstate hidden field? Please explain.</p>

4,310,532 | 4,310,533 | Genetic Algorithm optimization - using the -O3 flag | <p>Working on a problem that requires a GA. I have all of that working and spent quite a bit of time trimming the fat and optimizing the code before resorting to compiler optimization. Because the GA runs as a result of user input it has to find a solution within a reasonable period of time, otherwise the UI stalls and it just won't play well at all. I got this binary GA solving a 27 variable problem in about 0.1s on an iPhone 3GS.</p>
<p>In order to achieve this level of performance the entire GA was coded in C, not Objective-C.</p>
<p>In a search for a further reduction of run time I was considering the idea of using the "-O3" optimization switch only for the solver module. I tried it and it cut run time nearly in half.</p>
<p>Should I be concerned about any gotcha's by setting optimization to "-O3"? Keep in mind that I am doing this at the file level and not for the entire project.</p>

1,355,352 | 1,355,353 | Android Development: How do graphics work in Android? | <p>I am an android development beginner with some experience in other object oriented languages like java, python, c#. So I have created various games before in Java, using buffers and graphics to draw lines and stuff. How do I do that stuff in android? I looked at some online guides, and they all seem to create a class to extend a View object, and the class will overrule the onDraw method, where they can cause the Canvas or something to draw a line.</p>
<p>But what if you want to draw a line based on user input? That method wouldn't work then would it?</p>
<p>For example, what is the simplest code for which I could draw a circle where the user touches the screen?</p>
<p>Also, i was wondering what books people would reccomend for beginners, especially one that includes stuff on graphics? I user the developer site for android, but I feel a book would also help a lot to understand android? Any suggestoins?</p>

3,750,149 | 3,750,150 | In JavaScript doing a simple shipping and handling calculation | <p>I am having trouble with a simple JavaScript calculation. My document is supposed to add $1.50 to an order if it is $25 or less, or add 10% of the order if it is more then $25. The exact problem is: </p>
<p>Many companies normally charge a shipping and handling charge for purchases. Create a Web page that allows a user to enter a purchase price into a text box and includes a JavaScript function that calculates shipping and handling. Add functionality to the script that adds a minimum shipping and handling charge of $1.50 for any purchase that is less than or equal to $25.00. For any orders over $25.00, add 10% to the total purchase price for shipping and handling, but do not include the $1.50 minimum shipping and handling charge. The formula for calculating a percentage is price * percent / 100. For example, the formula for calculating 10% of a $50.00 purchase price is 50 * 10 / 100, which results in a shipping and handling charge of $5.00. After you determine the total cost of the order (purchase plus shipping and handling), display it in an alert dialog box.</p>
<p>This is my code:</p>
<pre><code> var price = window.prompt("What is the purchase price?", 0);
var shipping = calculateShipping(price);
var total = price + shipping;
function calculateShipping(price){
if (price <= 25){
return 1.5;
}
else{
return price * 10 / 100
}
}
window.alert("Your total is $" + total + ".");
</code></pre>
<p>When testing I enter a number in the prompt box, and instead of calculating as if I entered a number it calculates as if I entered a string. i.e. i enter 19 and it gives me 191.5 or I enter 26 and it gives me 262.6</p>

4,190,072 | 4,190,073 | Why does a global application context not work with "getassets" | <p>Just ironed out a bug in my Android app. I was trying to use getAssets() to pull a file from my assets directory. I subclassed Application and returned a "getApplicationContext" object so that all my classes can use a context whenever they need to.</p>
<p>But after much headache and NullPointerExceptions, it turns out that I needed to pass a local context variable and use THAT instead. If I use a global application context, getAssets doesn't work!</p>
<p>So why is this? What's so special about a local context variable that makes it work. I thought any old "Context" variable was enough to access the necessary methods and make them work properly!</p>

3,540,278 | 3,540,279 | Understanding Global & Local Scope in Javascript | <p>I've been learning Javascript using <a href="http://www.packtpub.com/object-oriented-javascript/book" rel="nofollow">Object-Oriented JavaScript by Stoyan Stefanov</a></p>
<p>He offers an example comparing global and local scope:</p>
<pre><code>var a = 123;
function f() {
alert(a);
var a = 1;
alert(a);
}
f();
</code></pre>
<p>Looking at this example, I expected the first alert to be '123' and the second alert to be '1'. Lo and behold, Stoyan says:</p>
<blockquote>
<p>You might expect that the first alert() will display 123 (the value of
the global variable a) and the second will display 1 (the local a).
This is not the case. The first alert will show “undefined”. This is
because inside the function the local scope is more important than the
global scope. So a local variable overwrites any global variable with
the same name. At the time of the first alert() a was not yet defined
(hence the value undefined) but it still existed in the local space.</p>
</blockquote>
<p>The explanation was not clear to me, how can the local variable overwrite the global variable in the first alert? Any other/different explanations would be appreciated.</p>
