You can access onlineCompiler.org here. This is a joint project by CodeControl and Ajay Jain. OnlineCompiler.org has a lot of features that will make online development quite comfortable and fun. You can save your prohects over there, take a backup and retrieve it later, or may be download it. It is specially useful in cases when you need to do something and they don't have a compiler.
Currently onlinecompiler.org supports only Unix/Linux GCC based C/C++. We are planning to introduce Python support very soon. But no official dates. :-)
Hope you will like it. For any queries, comments, appreciation or crtisim, just comment out here. We will be glad to hear from you.
