1,900,337 | 1,900,338 | jQuery.extend and jQuery.fn.extend | <p>I am making some test with <code>extend</code> and I got a little puzzled after some observations I made. First observations:</p>
<pre><code>console.log($.extend === $.fn.extend); // trure
// and since $ === jQuery then ...
console.log(jQuery.extend === jQuery.fn.extend); // true
</code></pre>
<p>So far so good, isn't it? Given the above results I then thought that doing this:</p>
<pre><code>// SNIPPET 1
$.extend({
log: function(m) {
console.log(m);
}
});
</code></pre>
<p>and this:</p>
<pre><code>// SNIPPET 2
$.fn.extend({
log: function(m) {
console.log(m);
}
});
</code></pre>
<p>was the same very thing. But in fact things stand in a very different way. In fact if you run SNIPPET 1 and then do:</p>
<pre><code>$("body").log("whatever");
</code></pre>
<p>you get an error (log is not defined). But you can do:</p>
<pre><code>$.log("whatever");
</code></pre>
<p>If you run instead SNIPPET 2 you get the opposite result, that is to say:</p>
<pre><code>$("body").log("whatever"); // this will work
$.log("whatever"); // this won't
</code></pre>
<p>What the heck? I appreciate the fact that <code>.extend</code> extends the object against which it is executed (<code>$</code> vs <code>$.prototype</code>) but what I do not get is how iit does it! Expecially given the fact that:</p>
<pre><code>$.extend === $.fn.extend // true
</code></pre>
<p>The function is the same!! How can it produce 2 different results?</p>

4,953,935 | 4,953,936 | ASP.NET security | <p>I'm currently converting our company database application from VB to ASP.NET. This is pretty much my first ASP.NET application, and I had a question about security. I would like some users to have the ability to add or edit data, while other users can only view and print reports. Now, as I understand it, in ASP.NET, I can use form-based authentication to restrict access to certain pages, but what I really would like to do is use the same web page for not only viewing the data, but also editing it (using a grid view). I don't see how I can do that using forms-based authentication without having separate (but similar) web pages in different folders, each with it's own level of security.</p>
<p>I guess I could always use the same web page, then check the users roles to determine if I should enable the 'edit' button or not. Is that a good (and common) programming practice?</p>
<p>Thanks</p>

4,924,702 | 4,924,703 | How to pass data from Java applet to client side python script? | <p>I have a python script which does various number-crunching jobs and now need to put a graphical front-end on it (a molecular editor in which a user draws a compound to pass to the script) to allow others in the lab to use it more easily. The available editors are Java applets, standalone Java or written in JavaScript. </p>
<p>I would greatly appreciate any advice on the best strategy to put the editor and script together. I really don't want to get into client/server arrangement and envisage a self-contained install on each machine i.e. "client only". Is it better to start off in javascript and pass the output in some way to python and then run the python script from within js. Or (preferably) is there some way to run applets (or standalone java) within python e.g. in Tkinter or some other GUI and "on-click" take the output from the editor into the python script for the crunching bit. </p>
<p>Thanks for any pointers - book chapters, useful projects/libraries and links to examples would be great. </p>

I understand the basic language structure, it being similar to C. It is all of the function calls and class calls that seem to go nowhere and the fact that a var can be declared in the <strong>!middle of an expression!</strong> that is spinning my head, oh and the fact that there is zero "0" documentation.</p>
<p>What is the best <strong>method</strong> (and/or) <strong>tool</strong> (and/or) <strong>reference material</strong> to convert the php into java code?</p>
<p>edit: There is 3 reasons that I am having to convert the php to java. </p>
<ol>
<li>The usual reason, my boss told me too.</li>
<li>The php is too slow, it is taking <strong>minutes</strong> sometimes to run a request to the server. </li>
<li>php is a nightmare to scale and maintain.(at least for us strong typed language types)</li>

<li>Onload - get() function (retrieves data for both divs)</li>
<li>The move() function is activated via a button</li>
<li>move.php has the mysql_query update action</li>
<li>Reload the div with the updated database information.</li>

If anyone has a better title for this, please go ahead and edit it; I can't think of what else to call it. I am printing a button from PHP using <code>echo</code>.

The problem I'm having is that the echoed string has to have quotes around it, the <code>onclick</code> event has to have quotes around it, and the parameter passed to the JavaScript function has to have quotes around it. I tried escpaing the quotes for the parameter with backslashes but that didn't work. Can anyone help me?</p>

<p>But when I access the src bit using jQuery, jQuery gives me back:</p>

<p>This is causing problems in some comparisons I'm doing. I don't want to change my image paths to use absolute URLs.</p>
<p>Any ideas as to how I can either get the absolute URL from the image path (this might not be as simple as concatenating the domain - since the URLs may occasionally be absolute), or get the path I provided in the HTML? Either way I need them to match up.</p>
<h3>Edit per comment from activa</h3>
<p>There's not really a lot of jQuery code to post, I'm using the <a href="http://malsup.com/jquery/cycle/">cycle</a> plugin, and in the <code>onbefore</code> function, I'm just calling <code>next.src</code>. My jQuery and JavaScript foo isn't sufficient to really understand what the cycle plugin is doing to generate <code>next</code> - I think it's the DOM element for the next image being cycled in, if you're familiar with what cycle does.</p>
<p>My image tag is actually this:</p>
<pre><code><img src="/site_media/photologue/photos/cache/6927d406810ee9750a754606dcb61d28.jpg" alt="" class="landscape slideshow-image-1" />
</code></pre>
<p>and in my <code>onbefore</code> function this code:</p>
<pre><code>alert(next.src);
</code></pre>
<p>results in an alert with:</p>
<pre><code>http://127.0.0.1:8000/site_media/photologue/photos/cache/6927d406810ee9750a754606dcb61d28.jpg

<p>To see what I mean, find a text link on this page and try to click inside it and drag to select it. It won't let you -- you'll have to click outside the link and drag around it.</p>
<p>What do you need to do in JavaScript/JQuery to temporarily disable the link long enough for you to drag and highlight it? </p>

<p>where <code>father</code>, <code>mother</code>, and <code>spouse</code> are referencing the <code>id</code> column of the same table. The root node will have null for father and mother.</p>

<pre><code><div id="uxcParent">
<div id="uxcClickable"></div>
</div>
</code></pre>
<p>now when a user clicks in the inner element i want the mouse position with respect to the parent div and not the page.</p>
<p>this what i tried.</p>
<pre><code> var x= e.pageX- obj.offsetLeft;
var y= e.pageY- obj.offsetTop;
</code></pre>
<p>this works fine only when i don't scroll the page. I want the function to return the same values no matter where my elements are on the same page.</p>
<p><b>update</b>:</p>
<p>i think it was not clear enough. am detailing more now..</p>
<p>consider that the elements are in the document in x position with respect to the document. the page has a scroll bar. now i can scroll to any part of the page and the position is still going to be x. but the position with respect to the view port would have changed. so pageX and pageY will give different values. this is my catch.</p>
<p>my elements can be anywhere in the view port and when i go over the inner element i should get co-ordinates with respect to the parent only(should not be influenced by where the parent is)</p>
<p>hope i am clear now.</p>

4,474,473 | 4,474,474 | Weird stuttering issues that I cannot get rid of (full source included) | <p>I based my game off the lunarlander example and have been having stuttering issues since I first started making it. Nothing I have tried has gotten rid of them so I have gotten to the point where I have spent a few hours creating a stripped down version of the lunarlander example, and put a simple scrolling image in to show the stuttering. NOTE: it is not related to the garbage collector. If you think it is, just look at the log, the garbage collector runs no-where near as often as the stutter appears.</p>
<p>The image that scrolls down the screen stutters approximately every second for about 1/10th of a second on my phone (Motorola Milestone, 2.2). This kind of stuttering does not exactly completely destroy gameplay, but it is very distracting and frustrating. My game also involves a lot of fast scrolling and quick movements so it is generally more obvious there.</p>
<p>If any of you have the time could you take a quick look at this eclipse project and see if:</p>
<ol>
<li>It stutters for you on your phone (look closely as it scrolls, it has a small hitch every half second to second and a half)</li>
<li>If you can see any way to fix the stuttering</li>
</ol>
<p>I am hoping I simply have a retarded line of code that is causing this whole thing without me realising. I just can't believe that even after stripping out this much it still has the exact same amount of stutter as my full game with 1000 objects, especially since it runs at a solid 60fps on my phone.</p>
<p>EDIT: Have profiled my game on Traceview, it seems fine.</p>

5,542,779 | 5,542,780 | .NET port with Java's Map, Set, HashMap | <p>I am porting Java code in .NET and I am stuck in the following lines that (behave unexpectedly in .NET).</p>
<p><strong>Java</strong>:</p>
<pre><code>Map<Set<State>, Set<State>> sets = new HashMap<Set<State>, Set<State>>();
Set<State> p = new HashSet<State>();
if (!sets.containsKey(p)) { ... }
</code></pre>
<p>The equivalent <strong>.NET</strong> code could possibly be:</p>
<pre><code>IDictionary<HashSet<State>, HashSet<State>> sets = new Dictionary<HashSet<State>, HashSet<State>>();
HashSet<State> p = new HashSet<State>();
if (!sets.containsKey(p)) { /* (Add to a list). Always get here in .NET (??) */ }
</code></pre>
<p>However the code comparison fails, the program think that "sets" never contain Key "p" and eventually results in OutOfMemoryException.</p>
<p>Perhaps I am missing something, object equality and identity might be different between Java and .NET.</p>
<p><em>I tried implementing IComparable and IEquatable in class State but the results were the same.</em></p>
<p><strong>Edit:</strong> </p>
<p>What the code does is: If the sets does not contain key "p" (which is a HashSet) it is going to add "p" at the end of a LinkedList>.</p>
<p>The State class (Java) is a simple class defined as:</p>
<pre><code>public class State implements Comparable<State> {
boolean accept;
Set<Transition> transitions;
int number;
int id;
// ...
public int compareTo(State s) {
return s.id - id;
}
public boolean equals(Object obj) {
return super.equals(obj);
}
public int hashCode() {
return super.hashCode();

425,705 | 425,706 | Does java have an equivalent to python __call__? | <p>Just started learning python, I've come across <code>__call__</code> method. I understand when <code>__init__</code> gets called and when <code>__call__</code> gets called by running a simple example:</p>
<pre><code>class Constructor:
def __init__(self, a):
print "__init__ called"
def __call__(self):
print "__call__ called"
def dummy(self):
print "a dummy method called"
print "creating x obj"
x = Constructor(1)
print "calling x object"
x()
</code></pre>
<p>console output:</p>
<pre><code>creating x obj
__init__ called
calling x object
__call__ called
</code></pre>
<p>My questions are:</p>
<ol>
<li>I come from java background, I know <code>__init__</code> maps to java constructor, does java have an equivalent to <code>__call__</code> to help me understand this better?</li>
<li>Can someone give me a simple example of when <code>__call__</code> can be useful?</li>
</ol>

3,917,677 | 3,917,678 | Show information based on what button that was pressed | <p>I'm making a information app for Android and I can't figure out how to change a button depending on which button was pressed in a previous class.</p>
<p>I made this picture that shows how the app works: </p>
<p><img src="http://i.imgur.com/Q3a5f.jpg" alt="Flowchart"></p>
<p>After clicking the first button you get to a new class with 2 new buttons that sends you to the same class but the 3 buttons there is supposed to change depending on which one of the two buttons you pressed, the three buttons you get sent to sends you to the same class but there is a TextView that changes text depending on what button you pressed.</p>
<p>So I need to add some kind of information to the button (an intent?) so it knows what you pressed earlier.</p>
<p>I'm kinda new to Java and Android so I'm sorry if I explained in a weird way.</p>
<p>Thanks in advance</p>

<p>I have search in google, I got some answer about using FindControl but it doesn't work. Any idea?</p>

<p>I can access the FormView1 component but no the validator inside the EditItemTemplate. How can I access control that is inside the EditTemplate?</p>
<h2>Edit2:</h2>
<p>If I try: <code>FormView1.FindControl("DateBirthdayValidator")</code> it compile but always return null. So still doesn't work but at least I can access the FormView1...</p>
