Well, I moved down to Norwich about 2 months ago from York, where I'd been doing a Computer Science degree, and I've started using Linux about 6 years ago, about 3 years ago started using it as my main OS.
Hmmm, now for why i'm interested in Linux. Well, because its better.... :-), and the politics... and I can actually do decent programming on it, and when something goes wrong with it, the answer is just a google away, because it supports my USB OHCI PCI card, and my tulip network card (which win 2k doesn't), because it has xfce4 and many other reasons....
As for me, the main programming languages I use are C++ and java, I currently maintain a latex editor called AmyEdit [1] , written using gtkmm in C++, (end shameless plug). I'm also the current KBounce International Champion! [2]
That's me, Hello!
