<p><strong>Possible Duplicate:</strong><br>
<a href="http://stackoverflow.com/questions/9864476/jquery-on-vs-live">jquery: on vs live</a> </p>
</blockquote>
<p>I have code that works just fine using <code>$('thing').live("mousemove", function(e) {</code> and <code>$('thing').live({mouseenter:function(e) {</code>. I notice jquery said <code>live</code> is depreciated and to use <code>on</code> so i did. However it doesn't seem to work the way i expect it to. I had mousemove events but since objects were loaded dynamically the events werent triggering which is why i use live. Now live works perfectly but when i use <code>on</code> as jquery suggested it seems to act like .mousemove and such. It works on objects that exist when the code is executed and not on dynamically added events (the whole reason i use live).</p>
<p>Is there a way to tell on to act like live and add events on new object? or do i use live?</p>

Most of the implementations that we override it with are domain-centric, i.e. in model classes. I'm yet to see an implementation of <code>equals</code> in a factory class or something equivalent.</p>
<p>My conclusion is that it was primarily put in to support the Java Collection API, so that it could deal with any <code>Object</code>. Else, it could have been left to be defined by specific domain designs.</p>

2,341,463 | 2,341,464 | How does Python handle globals? | <p>I've come across some very odd handling of global variables in Python. I was hoping someone can explain and justify these surprises!</p>
<p>A) This code prints 10 as expected:</p>
<pre><code>def func():
print(a)
a = 10
func()
</code></pre>
<p>B) This code throws an exception about referencing a too early:</p>
<pre><code>def func():
print(a)
a += 1
a = 10
func()
</code></pre>
<p>C) But this code prints [10] as expected:</p>
<pre><code>def func():
print(a)
a.append(1)
a = [10]
func()
</code></pre>
<p>So I can gather that the type of <code>a</code> changes its scope and additionally later statements that haven't even been reached yet change how <code>a</code> is seen. I know I can use <code>global a</code> at the start of the function but it's rather verbose.</p>
<p>Can anyone tell me what rules Python is using to handle its bizarre scoping?</p>

<pre><code>float f = 2.0f;
int i = (int)f; // causes conversion
</code></pre>
<p>I only want to copy the bit-pattern from f to i. How can this be done?</p>
<p>2.
The implicit and explicit operators in C# uses one intermediate object because the operator function is 'static'</p>
<pre><code>public static implicit operator MyClass(double s)
{
return new MyClass(s);
}
..
..
MyClass m = 2.2; // this code uses 'm' and one intermediate object.
</code></pre>
<p>This is fine for reference types, but for value-types which are big (say 20-30 bytes), this will cause unnecessary data copy. Is my understanding correct? And If yes, then why doesn't C# have a non-static conversion operator or user-defined assignment operator so that the conversion/assignment takes place on 'this'? If it does, whats the way to do it?</p>

I've been looking into taking the snapshot without root, and seems that most solutions use ddmlib and require the device to be constantly connected via USB. </p>
<p>The only solution that doesn't require root and a constant usb connection is the android screenshot library. However, from the forum comments as well as my experience with the demo app, this library doesn't work very reliably/consistently.</p>
<p>Is there any other solution? </p>
<p>Note: I've also looked at the Noroot Screenshotit app (<a href="https://play.google.com/store/apps/details?id=com.edwardkim.android.screenshotitfullnoroot&hl=en" rel="nofollow">https://play.google.com/store/apps/details?id=com.edwardkim.android.screenshotitfullnoroot&hl=en</a>), and seem like they have a similar approach to the android screenshot library, but have no idea how they make it more reliable. If anyone has an idea, that would be helpful as well.</p>

<p>Fairly straightforward code here...</p>
<pre><code>[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(statusBarWillChangeFrame:)
name:UIApplicationWillChangeStatusBarFrameNotification
object:nil];
</code></pre>
<p>But the notification never seems to be sent in that case, either on the Simulator by using the "Toggle In-Call Status Bar" option or on the device when a call ends with the application open. In addition, the similar UIApplicationDelegate method is not called.</p>
<p>According to the documentation,</p>
<blockquote>
<p><strong>UIApplicationWillChangeStatusBarFrameNotification</strong></p>
<p>Posted when the application is about
to change the frame of the status bar.</p>
<p>The userInfo dictionary contains an
NSValue object that encapsulates a
CGRect structure expressing the
location and size of the new status
bar frame. Use
UIApplicationStatusBarFrameUserInfoKey
to access this value.</p>
</blockquote>
<p>Can anyone explain why this notification is not being sent in response to the in-call status bar being shown or hidden? According to the documentation, it should be.</p>
