367,817 | 367,818 | Using jQuery's .add method | <p>Either I am making a very silly mistake here, or there is a bug with jQuery's <code>.add</code> method. Most likely the former.</p>
<p>I am trying to implement a list of items that could be selected. Here's my <a href="http://jsfiddle.net/2weq2/" rel="nofollow">code on jsfiddle</a>.</p>
<p>The test case that is failing is the following:</p>
<ol>
<li>Click the first element to select it.</li>
<li>Ctrl-click the second element to select it too.</li>
<li>Then click the third element (without <code>Ctrl</code>).</li>
</ol>
<p>Now, I'd expect the first and second to be de-selected, I believe the implementation also does this. But the second one does not get de-selected.</p>
<p>Digging a little, it seems that the <code>.add</code> is actually not adding my elements to the jQuery object set and for the life of me, I can't figure out why.</p>
<p>Any suggestions on this? Or is this not the way the <code>.add</code> method is supposed to be used?</p>
<p><strong>Edit</strong>: I know jquery-ui has a control for this kind of thing, but I have already evaluated it and it does not work for me. Thanks.</p>

2,582,178 | 2,582,179 | Using java arrays | <p>I have 7 lines of data in a text file (shown below). </p>
<pre><code>name: abcd
temp: 623.2
vel: 8
name: xyz
temp: 432
vel: 7.6
</code></pre>
<p>Using regex, I was able to read this data and I have been able to print it out. Now I need to store this data in some variable. I'm leaning towards storing this data in an array/ matrix. So physically, it would look something like this:</p>
<pre><code> data = [abcd, 623.2, 8
xyz, 432, 7.6]
</code></pre>
<p>So in effect, 1st row contains the first 3 lines, the 2nd row contains lines from 5 to 7. My reason for choosing this type of variable for storage is that in the long run, calling out the data will be simpler - as in: </p>
<pre><code> data[0][0] = abcd
data[1][1] = 432
</code></pre>
<p>I can't use the java matrix files from math.nist.gov because I'm not the root user and getting the IT dept to install stuff on my machine is proving to be a MAJOR waste of time. So I want to work with the resources I have - which is Eclipse and a java installation version 1.6. </p>
<p>I want to get this data and store it into a java array variable. What I wanted to know is: is choosing the array variable the right way to proceed? Or should I use a vector variable (altho, in my opinion, using a vector variable will complicate stuff)? or is there some other variable that will <strong>allow me to store data easily and call it out easily</strong>?</p>
<p>Btw, a little more details regarding my java installation - in case it helps in some way:</p>

the first digit from the left is divisible by 1, good, continue<br>
the first 2 digits from the left are divisible by 2, good, continue<br>

the first 4 digits from the left are NOT divisible by 4, you get a remainder, bad, restart with different numbers, or go back until one of the numbers can be replaced (the even spaces are pretty interchangeable)<br>
the tricky part here is that you cant use the same integer twice<br>

1,401,255 | 1,401,256 | Iframe loading time with multiple sources, 1 value is always bad | <p>I got a script witch puts urls from a txt file into an iframe, then checks the loading time of each source. If i have 4urls in my txt file, i get 3 results witch are good enough for me, but 1 result is always too short (says frame loaded in 0,016 seconds or so, where others take 1-4 seconds to load). If i delete other urls from my list, and only leave the one that gives bad value and then run my script - i get a normal value (few seconds to load).</p>
<p>Heres the script im talking about:</p>
<pre><code><script type="text/javascript">
$.get("imones.txt", function (data) {
var array = data.split(/\r\n|\r|\n/);
var beforeloadingtime = (new Date()).getTime();
var beforeTime = [];
beforeTime[0] = beforeloadingtime;
$.each(array, function (index, value) {
var jsonnuorodos = "http://anyorigin.com/get?url=" + array[index] + "&callback=?";
$.getJSON(jsonnuorodos, function (data) {
var iframe = $("#frame_id")[0];
var doc = iframe.document;
if (iframe.contentDocument) {
doc = iframe.contentDocument;
} else if (iframe.contentWindow) {
doc = iframe.contentWindow.document;
}
doc.open();
doc.writeln(data.contents);
doc.close();
var loadingtime = (new Date()).getTime();
beforeTime.push(loadingtime);
for (i = 0; i < array.length; i++) {
var result;
result = (beforeTime[i + 1] - beforeTime[i]) / 1000;
$("#loadingtimediv" + i).html(result);
}
});
});
});
</script>
</code></pre>
<p>Why do i get this inacurate result when running my script when i have multiple urls?</p>
<p>Edit: i think my script doesnt actually wait for 1 url to load completely before adding the next one, can this be the reason im getting false results?</p>

3,834,173 | 3,834,174 | Is there a way to load javascript scripts concurrently? | <p>Probably not. But still would be nice to have it. Kinda hard to believe that modern standards do not support it.</p>
<p><strong>Update</strong>: I would like to load scripts concurrently as opposed to the asynchronous scripts execution. So that if there are 10 scripts to load (9 small, 1 big) - in that case the big script won't "stuck" the download of the smaller ones.</p>

1,083,000 | 1,083,001 | Most efficient way to package php API | <p>I am writing a small api that will involve a number of "commands" with common elements, which involve reading parameters POST'ed to the script(s) and acted upon accordingly</p>
<p>I would like to have the most optimum execution, and am not sure if it's better to have one largish script that switches on a $cmd variable, or to have each command in it's own script.</p>
<p>it all really depends on how php handles script execution. if for example, the script is parsed and tokenized each time on the fly, it would be better to have a lot of short scripts that don't have redundant code being loaded and parsed/tokenized each time.</p>
<p>if however php reads,parses and tokenizes the scripts, and caches the "instructions" in memory, only re-loading/parsing/tokenizeing when the script has actually been edited (eg based on filedate), it would be better to have it all in one script, as then the code could be factorized into functions, and would be easier to maintain, as there would be no repeated code. i don't like the idea of including common files, if that inclusion invokes a reparse each time.</p>
<p>hopefully this question is not to generic in nature - i see no need to give sample code as i am really just wanting to know the best way to "package" my api </p>

5,749,096 | 5,749,097 | How can I make my program return to the beginning in Python? | <p>I'm a really new programmer, just programing for fun. I usually write my programs with a series of while loops to get to different sections of the program at different times. It's probably not the best way, but it's all I know how to do. </p>
<p>For example, I'm working on a little program that runs in a shell meant to solve an equation. Here's part of the program that's supposed to bring you back to the beginning.</p>
<pre><code>while loop==4:
goagain = raw_input("Would you like to do the equation again? (Y/N)")
if goagain == "Y":
#Get values again
loop=2
elif goagain == "N":
print "Bye!"
#End program
loop=0
else:
print"Sorry, that wasn't Y or N. Try again."
</code></pre>
<p>I have it set so that while loop==2, it gets the values to put into the equation and while loop==0, nothing happens. </p>
<p>The problem I have, though, is that when my loop changes back to 2, the program just ends there. It doesn't want to back in the code to where I told it what to do while loop==2.</p>
<p>So what I need to know is how to get my program to go back to that section. Should I use a different method than the while loops? Or is there a way to get my program to go back to that section?</p>

2,858,263 | 2,858,264 | WinForms/C#: Implementing long scrollable list of images blows up memory | <p>I try to load jpg-images as a long list of picture boxes into a table layout panel. The list of the images should be scrollable smoothly, i.e. without flickering or visible blurring or dithering. There are around 300 images, each with a size of around 150kb (600px x 850px).</p>
<p>The problem is that when loading the images into the panel, the memory (RAM) is much more blown up that it should be (considered the size of the images files). If the list is loaded, around 500Mb are blocked in memory, but the images should need around 300 x 150kb = 45MB. </p>
<p>It does not matter if I load the image into the picturebox directly or as MemoryStream: The result concerning the memory load is the same.</p>
<p>So, something is blowing up my memory-load, to an extent of more than 10 times as much as the image files would need.</p>
<p>The question is: How can I get the memory load under around 100Mb without changing image quality or image size. Does anyone have a good idea?</p>
