Since I am using Debian most of my free time, I decided to re-write Not Idle Task tool for Linux. Voilà:
If you have no idea what the “Not Idle Task” tool does, please consult the following page: http://www.shcherbyna.com/?page_id=1382
This version is tested in Debian 6 x86_64 and Fedora 16 x86_64 and is supposed to work in KDE based distributions. I have some ideas about Windows and Mac OS X support, and I guess I will release versions for these operating systems soon.
