111,562 | 111,563 | triggering jquery on dynamic elements | <p>I'm trying to trigger a <code>.show</code> on a div, when a link has a dynamically added class and it's parent has the class <code>pdSelectedSwatch</code> which is added on selection(click).</p>
<p>example code:</p>

<a href="javascript:void(0)" class="outOfStock">

</li>

<p>But I can't get it to work properly, and I'm betting my syntax is off.</p>
<p>I should note that the <code>outOfStock</code> class is determined by values in an xml file, and there are several functions that determine the link's class based on that file.</p>

5,686,159 | 5,686,160 | Animation of different images in list | <p>I have different images, say 100 images or so. Now, I want to apply animation on them. I want my ImageView to get each image after specified interval but when the change of image occurs, each image should FadeIn or FadeOut. I place my images in @drawable/[list_of_images].xml file as:</p>
<pre><code><animation-list xmlns:android="http://schemas.android.com/apk/res/android"
android:oneshot="false">
<item android:drawable="@drawable/a1" android:duration="1000"/>
<item android:drawable="@drawable/a2" android:duration="2000"/>
<item android:drawable="@drawable/a3" android:duration="3000"/>
<item android:drawable="@drawable/a4" android:duration="500"/>
</code></pre>
<p></p>
<p>and then I can successfully change these images depending on their time interval in ImageView by using:</p>
<pre><code>public class AnimTest extends Activity
{
AnimationDrawable myAnim;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.anim);
ImageView myIV = (ImageView) findViewById(R.id.image_view);
myIV.setBackgroundResource(R.drawable.list_of_images.xml);
myAnim = (AnimationDrawable) myIV.getBackground();

{

{
myAnim.start();
return true;
}
return super.onTouchEvent(event);
}
</code></pre>
<p>}</p>
<p>The problem is that I can't figure out on how to apply fade effect on every single image, while they are getting changed by the above animation. I can apply fade animation on whole list of images but cannot do this on every image. Am i going to the right direction to achieve this functionality? If not, please guide me to the right path.</p>

2,034,993 | 2,034,994 | Python: Object identity assertions thrown by differences in import statement notations | <p>When checking an object's identity, I am getting assertion errors because the object creation code imports the object-defining module under one notation (<code>base.other_stuff.BarCode</code>) and the identity-checking code imports that same module under a different notation (<code>other_stuff.BarCode</code>). (Please see below for gory details.)</p>
<p>It seems that the isinstance() call is sticky about the references to the object definition module, and wants it imported under the exact same notation. (I'm using version 2.5.)</p>
<p>I suppose could fix this by changing the import notation in the code checking the identity, but I'm worried that I'll just propagate the same problem to other code that depends on it. And I'm sure there is some more elegant solution that I probably should be using in the first place.</p>
<p>So how do I fix this?</p>
<p>DETAILS</p>
<p>PythonPath: '/', '/base/'</p>
<p>Files: </p>
<pre><code>/__init__.py
base/__init__.py
base/other_stuff/__init__.py
base/other_stuff/BarCode.py
base/stuff/__init__.py
camp/__init__.py
</code></pre>
<p>Text of base/stuff/FooCode.py:</p>
<pre><code>import other_stuff.BarCode as bc
class Foo:
def __init__(self, barThing):
assert isinstance(barThing, bc.Bar)

<p>Text of camp/new_code.py:</p>
<pre><code>import base.stuff.FooCode as fc
import base.other_stuff.BarCode as bc
thisBar = bc.Bar()
assert isinstance(thisBar, bc.Bar)
thisFoo = fc.Foo(barThing=thisBar)
</code></pre>
<p>This fails. It survives its assertion test, but blows up on the assertion in the initial code.</p>
<p>However, it works when I modify new_code to import BarCode.py with:</p>
<pre><code>import other_stuff.BarCode as bc
</code></pre>
<p>. . . because both base/ and base/other_stuff are on the PythonPath.</p>

<p>My initial thought was to create a copy of the original class:</p>

pass
Foo = _Foo
Foo.x = 1
Foo = _Foo # Clear added attributes
o = Foo()
print o.x # Should raise exception

<p>in case that would help but apparently it does not.</p>
<p><strong>clarification</strong>:</p>
<p>The user should not need to care about how the class is implemented. It should, therefore, have the same features of a "normally defined" class, i.e. introspection, built-in help, subclassing, etc. This pretty much rules out anything based on <code>__getattr__</code></p>

<p>This is quite trivial for simple classes like <code>Boolean, BigDecimal</code> etc. But it is proving somewhat problematic for converting a <code>Calendar</code> object.</p>
<p>I am not overly familiar with all the nuances of Calendars/Dates etc in Java so would appreciate some advice on converting my Calendar to a String and then back again.</p>
<p>When my application receives a request, it already has the Calendar constructed. It must then convert this to a String (1), pass it through the API (2), and then convert it back to a Calendar (3) on the other side.</p>

<p>Based on this, what is the easiest way to convert to and then from a String?</p>

a[i].x = rand()%3; //3 and 10 are just for testing isort
a[i].y = rand()%10;

439,790 | 439,791 | Resolving DNS in bulk | <p>I need to resolve a large number (hundreds of thousands) of domains to IP addresses in Java. While using <code>InetAddress.getByName()</code> is feasible for small numbers it is far to slow for use in large quantities (probably because it is only sending one request at a time to the DNS server and waiting for the response before moving on to the next one).</p>
<p>Is there a more efficient way (such as sending them to the DNS server in bulk) that would cut down the time required to resolve a large number of domains?</p>
<p>At fmucar's request I'm adding the code used to try a more multi-threaded approach:</p>
<pre><code>Set<String> ips = Collections.synchronizedSet(new HashSet<String>());
int i = 0;
List<Set<String>> sets = new ArrayList<Set<String>>();
for (String host : domains) {
if (i++ % 5 == 0) {
sets.add(new HashSet<String>());
}
Set<String> ipset = sets.get(sets.size()-1);
ipset.add(host);
}
for (Set<String> ipset : sets) {
Thread t = new Thread(new DomainResolver(ips, ipset));
t.start();
}
</code></pre>
<p>At 250 per thread we peaked around 700 results per minute. Which, while better than before (<300) was still not that great when needing to resolve hundreds of thousands. Lowering it to only 5 per thread greatly speeds this up to several thousand per minute. This obviously creates an insane amount of threads though, so presently investigating doing the resolving in C to make use of <a href="http://www.chiark.greenend.org.uk/~ian/adns/" rel="nofollow">http://www.chiark.greenend.org.uk/~ian/adns/</a> </p>

2,943,219 | 2,943,220 | Try Catch errors when setting attributes | <p>Is there a rule of thumb to follow for error catching while setting attributes of an object? Let's say for example that you have a Shape class as follows:</p>

def __init__(self, size):
self.size = size
</code></pre>
<p>I can do the following:</p>
<blockquote>
<p>>>> s = Shape(3)</p>
<p>>>> s.size</p>
<p>3</p>
<p>>>> s.size = "hello"</p>
<p>>>> s.size</p>
<p>'hello'</p>
</blockquote>
<p>But what if the attribute must be numeric? How do I catch TypeErrors in this situation? Do I put a try/except inside the <strong>init</strong> definition? This is my guess:</p>
<pre><code>class Shape():
def __init__(self, size):
try:
float(size)
self.size = size
except:
raise TypeError, "Value must be numeric"
</code></pre>
<p>This will catch the error on initialization but not when setting the attribute. How do I catch a TypeError when the user tries s.size = "hello" ?</p>
<p>Thank you!</p>
<p>I tried implementing the answer below and it didn't work:</p>
<pre><code>class Shape():
def __init(self, size):
self.size = size
@property
def size(self):
return self._size
@size.setter
def size(self, value):
self._size = float(value)
</code></pre>
<p>I get the following error message:</p>
<blockquote>
<p>Traceback (most recent call last): File "python_playground.py", line 18, in </p>
<pre><code>print s.size File "python_playground.py", line 9, in size
