CodePad ^[1] is a simple web based compiler/interpreter, and a collaboration tool. To get started – just paste your code, CodePad runs it and gives you a short URL which can shared with friends via chat or email. This application will be helpful when you have to quickly check code and you don’t have a handy interpreter.

It currently supports programming languages such as C, C++, PHP, Perl, Ruby, Python, Tcl and Scheme. By default the code pasted on CodePad is public. It lets you mark your code as private so that its not publicly available. This way only users to whom you send the link will be able to find your code. You can also create projects ^[2] to group your files and collaborate with your peers.
