I saw the SoundCloud group recording widget here (http://grouprecorder.soundcloudlabs.com) which looks great. I'm wondering if the widget returns the ID of a track once the user finishes uploading it. I'm asking because I want to put the widget in a larger form with fields for pictures, text, etc. and then associate the user's uploaded Soundcloud track with the other fields which are stored in my site's database.

compiling a small C++ program with Visual C++ Express
I opened hello.cpp. Why isn't there File -> Compile -> hello.cpp? What is an other easy way, if any?
Smoothly rotate and change size of UIView with shadow
I have a UIView with a shadow, and subview of the view is a UIImageView.
I want to resize the view when the iPad is rotated, and I'm trying to do this in willRotateToInterfaceOrientation.
If I set the shadow on the UIView in the basic way, the rotation is very choppy, so I'd like to use the suggestion by some people to set the shadow setting layer.shadowPath.
I have tried animating the frame size change using [UIView animateWithDuration:animations], and setting the new shadowPath in the same block, but the shadow path snaps to the new size.
And if I don't change the shadowPath in the animations block, it doesn't change.
From a few searches I've done, animating changes to layer stuff needs to be done with a CABasicAnimation.
So I think the question is, how do I animate a frame size and layer change simultaneously?
Hayes AT Commands: Detect Remote Hangup?
How are you supposed to programatically detect when the remote modem on your call hangs up? I am writing a C program which interfaces with a SoftModem device /dev/ttySL0 in Ubuntu linux. I am able to configure the modem using Hayes AT commands and communicate with the remote modem. However, I haven't been able to determine how I'm supposed to detect that the other end has hung up the line.
I have the modem configured so that when the other end hangs up, the device prints NO CARRIER and switches to command mode. However, I can't use the NO CARRIER string because I can't guarantee that the modem won't receive that string while in data mode.
How do you "listen" for remote hang up?

No Persistence provider for EntityManager named xx
I've searched entire SO, and although posts with the similar title exists this is a different scenario.
I've two projects in my eclipse 1) One JPA project 2) One Web project which consumes the entities from the JPA project. Both are OSGi and Maven enabled. I'm using the latest SpringFramework (3.1.1) for creating RESTful webservices in the Web project.
The project layouts are as follows:

Sorry for the huge post. But I export my persistence package in the Manifest file and import the same in my web app.
And the persistence provider used is org.eclipse.persistence.jpa.PersistenceProvider.
This has been stopping my project from a month.. :( Please help.
Thanks in advance.

Vertical Align Wrapper
I'm messing around with a website out of boredom, and trying to figure out how to vertical align my wrap, which I am failing at lol. I've already horizontally aligned it, and just need help vertical aligning it. (Yes, I have tried vertical-align:middle, but it doesn't work).
* { margin:0; padding:0; }
html { height:100%; }
body { background:/*url(images/bg.jpg)*/#14181a; }
#wrap { width:960px; height:55%; margin:0 auto; background:#293033; }
<div id="wrap">
<div id="logo"></div>
<div id="navgation"></div>
<div id="content"></div>
<div id="footer"></div>
</div>
