Linux celebrates tenth birthday

but you can bet there wasn't so much as a card from Bill Gates...

The OS was first released by Finnish computer science student Linus Torvalds in August 1991. Torvalds had created a Unix based operating system in his bedroom while studying at the University of Helsinki.
The operating system is based on the open source principle, which means it is freely available for anyone and can be modified as long as the source code is returned back to Linus Torvalds.
