<p>[UPDATE]
This is a SharePoint/ASP.Net enviroment so yes it's multithreaded. However none of the code I've written is doing any threading. This is a simple enough call results in a boolean type that an if statement seems to think false=true. I've tried a clean solution, restarting the dev enviroment, restarting the machine. I can't find any evidence that the code in the debugger is different to whats being executed.</p>

The code isn't very good as I've hacked it around a bit to try different things and investigate why this is going a bit wrong. Don't hold the bad code against me. For example userFound should really be named userNotFound</p>

$('#sideNav a:eq(4)').delay(300).animate({'margin-right': '0', 'opacity': '1'}, 500);

});
</script>
</code></pre>
<p>The first if statement works fine and the animations work but adding in the else if to make it disappear when you scroll back to the top seems to break it. The animations still work but they don't fire until a few seconds after the page has been scrolled to the appropriate place and they look slower and choppy. I think the problem is I need to check to see what state the menu is in and then stop the animations if it is already in that state but I'm not sure how to go about doing it. </p>

<p>How can I watch for changes in markup in <code><select></code> and, more importantly, <code><option></code> tags? </p>
<p>I <strong>don't</strong> want to listen for the <code>.change()</code> event (<code>onChange</code>), but I <strong>do</strong> want to listen for any changes in attributes (<code>disabled="disabled"</code>), values (<code>value="foo"</code>) or text.</p>
<h2>The long version</h2>
<p>I'm writing a simple <code><select></code> replacement plugin for jQuery. As one of the features, I'd like it to dynamically update with the select box. The one feature I'm stuck with is how to watch for events such as another piece of JS changing one of the <code><select></code>'s <code><option></code>s by, for example, changing it's text, value or disabled state.</p>
<p>I've found a question <a href="http://stackoverflow.com/questions/843318/jquery-modify-event">here</a> that provides a solution, however it just sets up a <code>setTimeout()</code> to poll the element.</p>
<p>Is there a clean (by which I mean "not using <code>setTimeout()</code>) way of watching for modifications of elements, specifically the <code><option></code>s inside a dropdown select control? The three main things I want to watch for are:</p>

<li>When it is disabled or enabled.</li>

This process is in a separate thread and works fine when I have 3G or WiFi available. I also have code that checks signal before actually running the thread so it won't attempt with no connectivity.</p>
<p>During my testing I walked into a building that blocked all signal so the proces started while I was outside and had signal but when I went inside the signal dropped and my Progress dialog just kept runnnig, I had to manually shut the program down to get it to recover.</p>

<p>I have a pool of 26 letters ('A' - 'Z'), and each letter can be used as many times as needed. I want to create lists using these letters; each list will be 10 letters long with no repeats inside them, and I want to guarantee that if I compare any two lists generated, there will be <em>exactly one</em> letter in common.</p>
<p>Questions:</p>
<ul>
<li>Is there a simple way to do this (i.e., by using library functions)?</li>
<li>Can I calculate the maximum number of lists I'll be able to create given the size of the pool (pool_size) and the length of the list (list_length)? </li>
</ul>
<p>Any pointers to relevant material would be appreciated; I don't need an implementation so much as somewhere to lay my Archimedean lever (to be read as: I need a foundation before I can build my idea).</p>
<p>"Give me a place to stand on, and I will move the earth." - Archimedes</p>
<p><strong>UPDATE</strong>: How naive of me to think that the alphabet was enough to work with. Let's expand the pool to 300 symbols, but keep the lists at length 10. Does that work?</p>

<p>But your last suggestion seems like a good idea; how do I revert the theme to the old version? Is this something your suggesting I do in the code or is there a place I can download the old version?</p>
<p><em><strong>Edit:</em></strong> On the download WP page for the 'Responsive Child theme/plug in' it says it's WordPress 2.8+ compatible - the base version I downloaded didn't specify it's compatibility so it may very well be an updated version not compatible with 2.8 - though I feel like I've seen that theme for years, so hopefully I can find an older version and get it going with the child theme. </p>
<p>-cheers!</p>

2,370,918 | 2,370,919 | android.app.Application invoking ArrayAdapter.notifyDataSetChanged | <p>I have a static class which extends android.app.Application (<strong>HireApplication</strong>) which is doing a lot of my background work. I create AsyncTasks here, I store the largest data objects that my application uses. I'm writing this code in the Application class so that I can reuse it between separate activities for Phones and Tablets.</p>
<p>This feels like the right way to layout my app, but now I have a problem. An AsyncTask has finished and needs to run notifyDataSetChanged on an ArrayAdapter within a Fragment (<strong>ListFragment</strong>).</p>
<p>Here is my solution:</p>
<p><strong>ListFragment:</strong></p>
<pre><code>public void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myListAdapter = new MyListAdapter(getActivity(), HireApplication.myList);
HireApplication.myListAdapter = myListAdapter; // Tell the application where the ListView is so that it can notifyDataSetChanged
}
</code></pre>
<p><strong>HireApplication:</strong></p>
<pre><code>public static ArrayAdapter<BikeStation> stationListAdapter = null;
private static void asyncTaskCompleteCallback() {
{...}
myListAdapter.notifyDataSetChanged();
}
</code></pre>
<p>Now, this works... but it doesn't feel right. I am giving the Application a reference back to a UI element which sounds like it's a bit tightly coupled, but I don't know a better way to do this.</p>
<p>Is there a better way of my Application notifying my ArrayAdapter or Fragment that it should take some action to update the UI with fresh data?</p>

4,265,810 | 4,265,811 | Reloading python module with flattened namespace | <p>I have a package with a similar structure as scipy/numpy, where you have a few main submodules, and each submodule contains functions from various files that have been flattened into the same namespace. Let's say</p>
<pre><code>package/
sub1/
__init__.py
file1.py
file2.py
</code></pre>
<p>And then <code>sub1/__init__.py</code> looks like this:</p>
<pre><code>from .file1 import func1, func2
from .file2 import func3
</code></pre>
<p>The result is that I can do</p>
<pre><code>import package.sub1
package.sub1.func1()
</code></pre>
<p><strong>However</strong>, the problem is that the following does not work:</p>
<pre><code>>>> import package.sub1
-- change things in file1.py --
>>> reload(package.sub1)
</code></pre>
<p>The function does not update. It works if I do <code>import package.sub1.file1</code> instead, so there is something with flattening the namespace, that makes it lose the connection to the module. My main question is how I can still use the <code>reload</code> command, while still getting the benefits of being able to write sibling functions in separate files.</p>

<pre><code>data = [(0.1,100), (0.13,300), (0.2,10)...
</code></pre>
<p>The first value in each tuple, the X value, only occurs once for the list of tuples. In other words, there can only be one value for 0.1 etc. </p>
<p>I then have a sorted list of buckets. A bucket is defined as a tuple containing a range and an id, as follows:</p>
<pre><code>buckets = [((0,0.14), 2), ((0.135,0.19), 1), ((0.19,0.21), 2), ((0.19,0.24), 3)...
</code></pre>
<p>A range is with respect to the X axis. So, the id 2 has two buckets above and ids 1 and 3 have only one, respectively. The first bucket for id 2 has a range from 0 to 0.14. Please note that buckets can overlap. </p>
<p>So, I need an algorithm which drops the data into the buckets and then adds up the scores. For the data above, the result would be:</p>
<pre><code>1:0
2:410
3:10
</code></pre>
<p>Notice how each piece of data is caught by a bucket associated with the id 2, hence it gets the score <code>100+300+10=410</code>.</p>

4,761,322 | 4,761,323 | handling a compute intensive operation | <p>I'm writing a web based application (large cargo aircraft weight and balance) in which the user enters pallet weights. When an individual pallet weight is entered, a number of checks have to be made to determine if that weight can be accepted. The checks are all relatively trivial in terms of compute cycles required; one is not. As I understand it, JavaScript is single-threaded, which I take to mean that if the user starts to enter a weight in another pallet position, he's going to be locked out until the previous weight is fully processed.</p>
<p>I can't afford to have the user waiting every time he enters a weight (which they don't have to do at the moment as the app currently doesn't make that last check properly). Currently I'm thinking of not doing the final compute-intensive step until all weights are entered and the user signifies so by clicking on a button. However, this will deprive the user of immediate feedback as to which weight initially triggered the problem, a problem in which multiple weights may contribute, and which is going to be hard to sort out if they have to wait until the last.</p>
<p>My Google searches on the topic have been somewhat useful, but I'm asking here for possible ideas for an up-to-date solution to the dilemma. Any suggestions are most welcome. The context of the problem can be observed by going to <a href="http://terryliittschwager.com/WB/JWB.php" rel="nofollow">http://terryliittschwager.com/WB/JWB.php</a> and selecting an aircraft.</p>
