Linux celebrates its 10th Birthday this weekend. Written by Finish programmer Linuz Tovalds whilst he was still sturdying at University, Linux can now be run on everything from handhelds such as the Compaq Ipaq right up to IBM mainframes and supercomputers.

Linux is a version of Unix which remains popular as it can be moved relatively easily from one make of computer to another. But while Unix was generally tied to expensive hardware vendors, Linux was intended to be a cheaper scaled down version. It is now a worldwide industry. Because of the openness and collaborative development associated with the Linux developmers, Linux is now finding place in many businesses tired of continuing price increases, upgrades and fixes.
