A question about open source led several people to point out that there are a number of histories of BSD available – Steve Mynott pointed at excerpts from Kirk McKusick‘s O’Reilly book. Sascha Wildner also included GrokLaw’s excellent and long history, and McKusick’s BSDTalk interview (.mp3). Local ‘expert on old things’ Bill Hacker added that BSD-style sharing of code was happening before Linux, GNU, or even Richard Stallman had been born.
