Linux is my preferred development environment. I keep a number of small projects here starting with a simple keyboard layout for X Windows.
TODO - Normal configuration and tools installed (this is difficult as I use so many tools - but should be able to get the basics).
Up until recently my preferred distribution has always been debian. I have been using and building Debian systems since its initial release mid 90s'. More recently I use Ubuntu - for my money it is best of both worlds - stability and packaging of debian, with regular updates. However I regularly still use Debian as a server and Ubuntu as a workstation.
