4,729,258 | 4,729,259 | Functions with dependencies passed as parameters | <p>I'm working on a project where I'm batch generating XML files which can import to the IDE of an industrial touchscreen.</p>
<p>Each XML file represents a screen, and most screens require the same functions and the process for dealing with them is the same, with the exception of the fact that each screen type has a unique configuration function.</p>
<p>I'm using a <code>ScreenType</code> class to hold attributes specific to a screen type, so I decided to write a unique configuration for each type, and pass it as a parameter to the <code>__init__()</code> of this class. This way, when I pass around my <code>ScreenType</code> as it is needed, it's configuration function will stay bundled and can be used whenever needed. </p>
<p>But I'm not sure what will happen if my configuration function itself has a dependency. For example:</p>
<pre><code>def configure_inputdiag(a, b, c):
numerical_formatting = get_numerics(a)
# ...
return configured_object
</code></pre>
<p>Then, when it comes time to create an instance of a <code>ScreenType</code></p>
<pre><code>myscreentype = ScreenType(foo, man, shoe, configure_inputdiag)
</code></pre>
<p><code>get_numerics</code> is a module scoped function, but <code>myscreentype</code> could (and does) get passed within other modules. </p>
<p>Does this create a problem with dependencies? I'd try to test it myself, but it seems like I don't have a fundamental understanding behind what's going on when I pass a function as a parameter. I don't want to draw incorrect conclusions about what's happening.</p>
<p>What I've tried: Googling, Search SO, and I didn't find anything specifically for Python.</p>
<p>Thanks in advance.</p>

You can try it here:
<a href="http://sn2010.x10.mx/" rel="nofollow">http://sn2010.x10.mx/</a></p>
<p>I'm not sure exactly why it's giving me that problem, but here's my codes on both pages:</p>
<p>index.html</p>
<pre><code> <form name="form1" action="pagetwo.php" method="POST">

echo "<hr align='left' width='680px' /><br /><br />";
$redirect = "Location: " . $_REQUEST["bootoon"] . ".php";

<p>Anyone know why the webpages are creating this error? I've tried using ob_start(); and ob_end_flush();. So those two codes are out of the picture...</p>

1,039,578 | 1,039,579 | Best way to stream audio and video from an Android phone to a RTMP server | <p>I'm looking for the best way to stream video and audio from an Android phone to a server using RTMP. I've spent some time on this problem and this far I've been able to stream video only using FFMPEG. There are many ways to build the lib for Android and I guess that with some more work I should be able to stream Audio too. </p>
<p>The thing is that I need to encode the video in h264 and the audio in AAC, and it would be very easy to do it using Android's <a href="http://developer.android.com/reference/android/media/MediaRecorder.html" rel="nofollow">MediaRecorder</a>. So I started looking for a RTMP library for Android and found this <a href="http://code.google.com/p/android-rtmp-client/" rel="nofollow">Red5 port</a> that seems to be working pretty well. Using it I can stream a video file stored on the phone very easily, and the audio is working too.</p>
<p>So my question is the following: Is there a way to connect Android's MediaRecorder output to the RTMP library? I guess the way would be to 'fake' a file in setOutputFile(), and then to send the data to the RTMP encoding methods, but I can't figure a way to do it. </p>
<p>Any clue is welcome, really. Thanks in advance. </p>

$(function () {
$("#myCheckbox").click(function(){
$("#display-hide").toggle(this.checked);
});
$("#display-hide").hide();
});
</script>
</code></pre>
<p>The first time I access the page, everything works fine (i.e. div is hidden - when I check the checkbox, the div is displayed).</p>
<p>BUT, when I come back to the page (to edit, for instance), no-matter the value of the checkbox (checked or not), the div is hidden first. The div becomes only visible after I uncheck then check again. </p>
<p>I guess that because of this statement:</p>
<pre><code>$("#display-hide").hide();

<p>Is there anyway to verify the value of the checkbox and hide/show the div accordingly?</p>

3,943,501 | 3,943,502 | Set initial height of div based on how much space is left inside of parent div | <p><strong>I have 3 divs:</strong></p>
<p><strong>.main_content, .content_top, .content_bottom</strong></p>
<p>.main_content is set to 100% but 100% is not the size of the browser window, it's inside the middle of my page.</p>
<p>.content_top is set at 60% height.</p>
<p><strong>I want to set the height of .content_bottom to the rest of the space available inside .main_content via javascript.</strong></p>
<p>For example, if .main_content was 800px high, and .content_top was 600px high, I want to set .content_bottom to 200px.</p>
<p>This is a simplified example, my situation is not as easy as specifying 40% or leaving the browser to decide. For one, there's currently 46px of padding on .content_top. I'm doing a split screen like interface between .content_top and .content_bottom dragging a bar to resize both. This is mostly working, just having trouble with the bottom portion. Being able to set .content_bottom to a specific height(i.e. 198px) would solve all of my current problems. Happy to elaborate on this example, as well as dig into some actual code, but was hoping there was an easy method for calculating this and was having trouble finding a good example that worked cross-browser, thanks!</p>

Each time I want to install the new version of the app on the device I need to connect it, enable USB Debugging, install the app, disable USB Debugging, unplug the device (optional). I was wondering if it was safe to just unplug the device without disabling USB Debugging. After all, the device is not mounted, right? But there is the adb, talking to it. It would be much more convenient to be able to do that. Does anyone know if it is safe or unsafe?</p>
