Rise of Linux – a hacker’s history

The original code of Linux was written for fun, or in Eric Raymond’s phrase, to ‘scratch the itch’ of Linus Torvalds, and later to satisfy the enthusiasm and programming itch of an assortment of hackers and hobbyists who, for the most part, had grown up in the age of the ZX80 and the BBC Micro, Acorns and Apricots, for which the code was often available – and hackable.
