The evolution of the UNIX time-sharing system - Dennis M. Ritchie

This quote fue agregado por riffcentric
During the past few years, the Unix operating system has come into wide use, so wide that its very name has become a trademark of Bell Laboratories. Its important characteristics have become known to many people. It has suffered much rewriting and tinkering since the first publication describing it in 1974, but few fundamental changes. However, Unix was born in 1969 not 1974, and the account of its development makes a little-known and perhaps instructive story.

1969... nice. (I'm not smart enough to say anything constructive sorry)
