<pre><code>$(document).ready(function () {

showHideZeroRowsEvent();
removeZeroOnClick();
bindMouseOverOutEvent();
bindTableRowEvents();
returnAsTabEvent();
budgetNivaChangedEvent();
</code></pre>
<p>});</p>
<p>as you see it contains some funtions, and those functions using child functions and so on.</p>
<p>here's a sample of a function using live</p>
<pre><code>function bindMouseOverOutEvent() {
$('#budgetTable tr').live({
mouseover: function () {

mouseout: function () {
$(this).find('td:eq(6)')
.addClass('budgetBelopp')
.end().toggleClass('budgetTable-hover');
}
});
</code></pre>
<p>}</p>
<p>but its not working because its wrapped in a function, and I want them to be wrapped so I see on the function name what the function is doing. </p>

4,955,340 | 4,955,341 | adding noise to a signal in python | <p>I want to add some random noise to some 100 bin signal that I am simulating in Python - to make it more realistic.</p>
<p>On a basic level, my first thought was to go bin by bin and just generate a random number between a certain range and add or subtract this from the signal.</p>
<p>I was hoping (as this is python) that there might a more intelligent way to do this via numpy or something. (I suppose that ideally a number drawn from a gaussian distribution and added to each bin would be better also.)</p>
<p>Thank you in advance of any replies.</p>
<hr>
<p>I'm just at the stage of planning my code, so I don't have anything to show. I was just thinking that there might be a more sophisticated way of generating the noise.</p>
<p>In terms out output, if I had 10 bins with the following values:</p>
<p>Bin 1: 1
Bin 2: 4
Bin 3: 9
Bin 4: 16
Bin 5: 25
Bin 6: 25
Bin 7: 16
Bin 8: 9
Bin 9: 4
Bin 10: 1</p>
<p>I just wondered if there was a pre-defined function that could add noise to give me something like:</p>
<p>Bin 1: 1.13
Bin 2: 4.21
Bin 3: 8.79
Bin 4: 16.08
Bin 5: 24.97
Bin 6: 25.14
Bin 7: 16.22
Bin 8: 8.90
Bin 9: 4.02
Bin 10: 0.91</p>
<p>If not, I will just go bin-by-bin and add a number selected from a gaussian distribution to each one.</p>
<p>Thank you.</p>
<hr>
<p>It's actually a signal from a radio telescope that I am simulating. I want to be able to eventually choose the signal to noise ratio of my simulation.</p>

Users have the ability to run one-off reports from the application. The reports are from from data which is created on the fly and saved to the individual user's pc. The data is deleted when the application is closed.</p>
<p>There is a 2 step process in the app to create the report. first, the report button is clicked, which creates the data in the local folder. then the the create report button is clicked, at which time the report is actually created using that data. As I said earlier, when the app is closed, all local data is deleted. </p>
<p>I have a need to collect this data so that it can be reported against. Currently, I have the user stop after the first step mentioned above and manually run a short program which copies the local data to a network share where it can be processed. I would like to eliminate the manual step of running the copy app.</p>
<p>How are people handling similar situations to this? I have less than 10 users who would need it, and it can be run once a day, sometimes as many as 5 times a day. I have considered creating a service to run locally on each users pc, but this seems like it would be difficult to maintain. Can a windows service be pushed out by a login script?</p>
<p>Does anyone have any other thoughts regarding how this could be handled?</p>

1,209,281 | 1,209,282 | ClassCastException Explanation | <p>Good day, i was having a little trouble with the following code below and i got a solution from a ticked answer in this link. I would like to know why.</p>
<p>Note: i had a similar type of layout as in the question, but with one TextView only.</p>
<p><a href="http://stackoverflow.com/questions/6054773/classcastexception-in-my-application">solution link here</a></p>
<p>my code below:</p>
<pre><code> public void onItemClick(AdapterView<?> av, View v, int position, long id) {
blueadapter.cancelDiscovery();
String info = ((TextView) v).getText().toString(); //classcastException here
String Bluetooth_address = info.substring(info.length()-17);
}
</code></pre>
<p>so from his solution, if i change this to this</p>
<pre><code>String info = ((TextView) v.findViewById(R.id.search_device_id)).getText().toString();
</code></pre>
<p>it solves my ClassCastException problem.</p>
<p>Now please can someone kindly explain to me or point me to the right direction, what he meant by in the answer <strong>"You receive the whole LinearLayout as the parameter v. You should try v.findViewById() and then use this textview."</strong> its nice it solves my problem, but i would like to understand why i had to do that?.. i have dealt with ListViews before, but i have not come across this, so its kind of strange for me. Thank you.</p>

5,875,863 | 5,875,864 | How does iOS determine to apply the autoresizing masks if launched on iPad? | <p><em>I do not know how to explain my question properly, but if anyone understand it is much appreciated else this question can be deleted.</em></p>
<p>I am making an universal application I wonder: The code I write in <code>loadView</code> I write positions of components specified in a iPhone points (320, 480). And from the documentation below it says that autoresizing is a response to their superview being moved or resized. So my question is how does the code/views know to autoresize when runned on a iPad? Because, are the superview (which is self.view) really resized? </p>
<p>Code you write outside of loadView and attaches to self.view and with iPhone positions (320, 480) are not automatically resized even though you use autoresizing masks.</p>
<p>I know this is for Mac OSX but: (Quote from <a href="http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/CocoaViewsGuide/WorkingWithAViewHierarchy/WorkingWithAViewHierarchy.html" rel="nofollow">Mac OSX Documentation</a>)</p>
<blockquote>
<p>Autoresizing of Subviews NSView
provides a mechanism for automatically
moving and resizing subviews in
response to their superview being
moved or resized. In many cases simply
configuring the autoresizing mask for
a view provides the appropriate
behavior for an application.
Autoresizing is on by default for
views created programmatically, but
you can turn it off using the
setAutoresizesSubviews: method.</p>

2,611,837 | 2,611,838 | Javascript .js loading issue | <p>I am editing an existing site, which is a typical merchant site. A series of PHP files with one main index that loads in the various content pages.</p>
<p>The main index.php, using <code><script></code>, loads in jsFunctions.js. </p>
<p>When ever I modify the jsFunctions.js file, the index only loads the jsFunctions.js partially. For example I will get a firebug error such as 'unterminated string literal' or 'missing end }' or similar. The errors themselves make sense, because the js file isn't fully loading, a brace or quote is missing and throwing an error. It is seemingly random, sometimes it will load 100 lines of the js, then sometimes 105 lines, etc. </p>
<p>But why would the file be partially loading if i edit it? If i remove the single line of my code, no matter how simple, it starts working again?</p>
