<p>I do have some sense of the "ugly" way to do it, as in keeping the same code base but have a build system that builds different versions for the platforms and keep different Java files around that get added in our out of the build based on which version is selected.

6,016,842 | 6,016,843 | Reading and writing pickles to an encoded stream | <p>A file format commonly used in our system is base64 encoded pickles - at the moment I can translate to and from strings in this trivial format with some simple code like this:</p>
<pre><code>def dumps( objinput ):
"""
Return an encoded cPickle
"""
return cpickle_dumps( objinput ).encode( ENCODING )
def loads( strinput ):
"""
Return an object from an encoded cpickle
"""
return cpickle_loads( strinput.decode( ENCODING ) )
</code></pre>
<p>I'd like to implement a new function, called "load" which works much like the standard pickle load function except that it will read just enough bytes from a stream and then return the decoded object. The trick here is to read just enough bytes - the cPickle.load function does this, it pops bytes off the stream until the pickled data is complete. My new function needs to look like this:</p>
<pre><code>def load( stream_input ):
""""
Return just one object popped from the stream.
If the stream has ended, raise an exception
Do not over-read the stream.
</code></pre>
<p>How might I do this when the data is base64 encoded pickle? The difficulty here seems to be that it's not obvious that this can be done either by wrapping the cPickle.load function or by wrapping the input stream, an additional difficulty is that what may be one-byte of pickle data may be encoded to more than one byte of base64 so it's not clear how to adapt stream_input.read(n) into something which is guaranteed to return n bytes of decoded data when the encoded input stream is base64.</p>

1,559,878 | 1,559,879 | Idiomatic way to print arbitrary number of items from a list on each line | <p>I want to print data from a list, such as:</p>
<pre><code>['0.10', '0.15', '-0.25', '0.30', '1.50', '1.70']
</code></pre>
<p>However, rather than printing one element in the list using something like:</p>
<pre><code>for item in list:
print item
</code></pre>
<p>I want to print an arbitrary number of items from the list on each line. I can think of many messy ways to do it and I saw an answer which used the grouper recipe from the itertools page on the docs. I'm happy to use that, but I suspect there might be a better way of doing it.</p>
<p>An example output I might like would be:</p>
<pre><code>0.10 0.15 -0.25
0.30 1.50 1.70
</code></pre>
<p>Or:</p>
<pre><code>0.10 0.15 -0.25 0.30
1.50 1.70
</code></pre>
<p>So the number of items on each line isn't necessarily a factor of the number of items on the list. Some lines may end with fewer elements if the list is too short.</p>

367,190 | 367,191 | displaying/adding to/removing from a list of items in asp.net? | <p>Users on my site can have any number of email addresses linked to their account. I'm making a page to do this. On page load, all the email addresses associated with a user are pulled from the database and displayed on the page. Then, the user should be able to add, edit and remove these emails.</p>
<p>Lots of websites need to do this, so I thought there might be existing tools that provide this functionality. Do any of the existing Controls do something like this?</p>
<p>I looked through the documentation, but there are lots of controls and it is hard to tell what it is possible to do with them.</p>
<p>I could make my own implementation, but I hate to reinvent the wheel (and it feels like this is something people should need to do all the time.)</p>
<p>Any suggestions?</p>

4,584,472 | 4,584,473 | How can I clear a timer when a variable is set to true? | <p>I'm just trying some JS animations, and I have animated a box that moves within borders, but I would like the animation to stop when the box hits one of the borders. This is one of the functions I use:</p>
<pre><code>function AnimMoveRight() {
var interval = setInterval("moveRight(10)", 40);
if (hitRight == true) {
clearInterval(interval);
}
}
</code></pre>
<p>The <code>moveRight(10)</code> changes the box'position for 10 pixels to the right. <code>hitRight</code> is set true when the box hits the right border. Well, obviously, this code doesn't work, it just keeps on looping the <code>moveRight()</code> function. Now, my question is, how do I cancel the interval from within the <code>AnimMoveRight()</code> function?</p>

<p>I want to be able to upload a file, and report on its progress. I've been playing with SWFUpload, and it seems like a bit to much messing around for my liking. Integrating it with code igniter just seems like it's going to cause headaches.</p>
<p>I want a visual progress indicator of some sort to show the user their upload hasn't stagnated. Even if it was just a spinner saying "Uploading. Do not close this window until upload is complete." that would be enough for me.</p>
<p>Security is the most important. Using something like SWFUpload is going to require passing variables to the upload form such as the user ID and other information I'd rather not give snooping noses the opportunity to sniff.</p>
<p>Any possible solutions. Help is much appreciated.</p>

<pre><code>l(x,y)=(l(x,y)-min)(no of intensity levels/(max-min)) + initial intensity level

<p>where, I( x,y ) represents the images, on the left side it represents the output image, while on the right side it represents the xth pixel in the yth column in the input image. In this equation the "min" and "max" are the minimum intensity value and the minimum intensity value in the current image. Here "no. of intensity levels" shows the total number of intensity values that can be assigned to a pixel. For example, normally in the gray-level images, the lowest possible intensity is 0, and the highest intensity value is 255. Thus "no. of intensity levels" is equal to 255.</p>
