Linux, Mono, Hello World...
Last night I decided to play on the other side of the fence. I downloaded Puppy (just a small variant of linux) and installed it on a 128MB pen drive. I boot from the pen drive itself. I didnt want to mess with any other HDD's and crap and since I wanted to carry the OS around with me it was just easier.
So, next I grabbed the Linux Installer for x86 (All distributions) of Mono installed it on the pen drive and compiled and ran my first "Hello World" application.
Amazingly easy.
