1,658,255 | 1,658,256 | PHP stream multiple videos at once | <p>I want to build a little streaming service, nothing like YouTube (there will be no options for users to upload videos themselves), I calculate with not much more than 100-200 concurrent streams at once. The videos are quite short, around 3-10 minutes in HD-quality and shouldn't be much bigger than 200mb. My question is, if this is possible with PHP and what kind of hardware would be needed, I thought maybe the hard drive read'n'write-rate could be too slow to stream 200 different videos at once...Any suggestions?</p>

4,005,857 | 4,005,858 | What's a good way to provide additional decoration/metadata for Python function parameters? | <p>We're considering using Python (IronPython, but I don't think that's relevant) to provide a sort of 'macro' support for another application, which controls a piece of equipment.</p>
<p>We'd like to write fairly simple functions in Python, which take a few arguments - these would be things like times and temperatures and positions. Different functions would take different arguments, and the main application would contain user interface (something like a property grid) which allows the users to provide values for the Python function arguments.</p>
<p>So, for example function1 might take a time and a temperature, and function2 might take a position and a couple of times.</p>
<p>We'd like to be able to dynamically build the user interface from the Python code. Things which are easy to do are to find a list of functions in a module, and (using inspect.getargspec) to get a list of arguments to each function.</p>
<p>However, just a list of argument names is not really enough - ideally we'd like to be able to include some more information about each argument - for instance, it's 'type' (high-level type - time, temperature, etc, not language-level type), and perhaps a 'friendly name' or description.</p>
<p>So, the question is, what are good 'pythonic' ways of adding this sort of information to a function.</p>
<p>The two possibilities I have thought of are:</p>
<ul>
<li><p>Use a strict naming convention for arguments, and then infer stuff about them from their names (fetched using getargspec)</p></li>
<li><p>Invent our own docstring meta-language (could be little more than CSV) and use the docstring for our metadata.</p></li>
</ul>
<p>Because Python seems pretty popular for building scripting into large apps, I imagine this is a solved problem with some common conventions, but I haven't been able to find them.</p>

3,101,998 | 3,101,999 | PHP - Alternate row colours based on a 'grouping' value in an array | <p>There's probably an easy answer to this, but I just haven't been able to get my head around it.</p>

)
</code></pre>
<p>What I would like to do is output this data to an HTML table and colour code the rows. I know how to alternate the row colours, but in this case I need it to be colour coded based on the 'meeting_grouping'. I.e.

2,337,404 | 2,337,405 | Randomly get a emtpy message in networkstream Read | <p>I am doing a multiple channels chatting project.
Everytime a client joined a channel, the server will broadcast the message that someone joined.</p>
<p>I have to make sure that the client only receive message belong to the channel that they are currently in.
So i did something like clientName$channelName^
clientName$JoinedChannelName^
I used $ and ^ to tell the program which substring is client name and channel name.
And of course, the program needs to know how to extract the channelName when the server is broadcast a client join event or a client message sent event, because then it can determine if the message belong to this channel.</p>
<p>things are fine but...
The broadcasting of client Joined is fine, and after i type some words that are supposed to send to the channel and the channel broadcast it correctly. BUT SOMEHOW, the client gets another empty message on it's networks stream.read. I checked the server and it didn't do any unnecessary broadcast. The empty message isn't a big issue, it can be easily fixed, but i want to know why...Please help if you encounter similar situation before,</p>
<p>Here is the trouble part of the code, i cannot give the entire codes since its awfully long...</p>
<pre><code> string chan_name = null;
serverStream = clientSocket.GetStream();
int buffSize = 0;
byte[] inStream = new byte[10025];

<p>page_load
Hookup event handlers such as my button click
page_preRender</p>
<p>Does this mean that if I put the databinding for the gridview in preRender, that is the only place I need to worry about calling it. I can remove it from the button click. This is what I think, but I am not sure if my thinking is correct, so I would like some more insight as to the benefit of putting code in PreRender as opposed to PageLoad</p>

<p>In my "D:/collection" folder, I have two types of files, that are "8-digit-number_type.dbf" and "character_type.dbf" as follows: 00093282.dbf, 00345602.dbf, 69209340.dbf, 69806980.dbf, 92406482.dbf, 93609360.dbf,..., aaa.dbf, bbb.dbf,.... </p>

<p>I want to take only the "8-digit-number_type.dbf" files, and exclude the "character_type.dbf" files from my analysis. I don't care about the "character_type.dbf" files.

1,482,145 | 1,482,146 | Dynamic casting in Java | <p>I have two parallel class hierarchies and I would like to convert objects from one to another. I can do it by manually specifying what conversion to do, but I need to specify the conversion twice: first when the actual conversion happens and second when I need to call it. Is there a way to specify it only once?</p>
<p>So here is the example, that works, but I would like to simplify. There are two convert functions that allow me to go between input classes (bI, cI) and output classes (bO, cO). This is unavoidable. The instanceof comparisons though bother me. Is there an elegant solution to avoid them?</p>
<pre><code>public class ConversionTest {
static public class aI {}
static public class bI extends aI {}
static public class cI extends aI {}
static public class aO {}
static public class bO extends aO {}
static public class cO extends aO {}
// Convert from bI to bO.
private static aO convert(bI iVar) {return new bO();}
// Convert from cI to cO.
private static aO convert(cI iVar) {return new cO();}
public static void main(String argv []) {
// Input variable.
final aI iVar = new bI();
// Output variable.
final aO temp;
// Perform conversion.
if(iVar instanceof bI) {
temp = convert((bI)iVar);
} else if (iVar instanceof cI) {
temp = convert((cI)iVar);
}
}
}
</code></pre>
<p>I would like to do something like that:</p>
<pre><code>final a0 temp = convert(iVar.getClass().cast(iVar));
</code></pre>
<p>But in this case, compiler complains that it can not find the proper convert function. Maybe I can specify an array of all possible conversions to try?</p>
<pre><code>final a0 temp = convertHelp({bI,cI}, iVar);
</code></pre>
<p>I am not sure how I should implement this <code>convertHelp</code> function. It would iterate through the array and try to find the proper casting. Any suggestions?</p>
<p>Thanks.</p>
