I support a few Freedom causes, I have learned how to program QuickBasic 4.5 into real time issues like firing the plugs on a 4 cylinder engine, designed and build the interface to the 25 pin printer port its was running my car for a few years off a Toshiba notebook. My next project was a 3 phase 4 bit D/A converter to drive speakers. I got side tracked with MP3StreetParty. I have been using and learning Ubuntu for some time now my forum has a section on it. I personally use Ubuntu 14.04 with a ThinLinc server installed on my P4. I have worked in the computer industry for over 10 years dealing with some servers I know about Citrix XP eg win 2000 server.
