(IDG) — FreeBSD, a port of BSD Unix to Intel, has been around almost as long as Linux has — but without the media hype. Its developer and user community recently got a chance to get together for the first time, and they did it in the city where BSD — the Berkeley Software Distribution — was born some 25 years ago.
October 17, 1999 marked a milestone in the history of FreeBSD — the first FreeBSD conference was held in the city where it all began, Berkeley, CA. Over 300 developers, users, and interested parties attended from around the globe.
