Code::Blocks is a complete, cross-platform integrated development environment for C and C++, built using the wxWidgets toolkit. Code::Blocks is available on Linux, Windows and OS X, so you may find it useful on Linux if you switched and are already used to it or an IDE like Dev-C++, for example.
Torrent is a great way to transfer large files very quickly.

Being able to run it in a screen session (also upon boot) makes it ideal to also control it from a remote location.
