UNIX is always diverging/converging. Here are a couple examples: 2) There was at least one major divergence inside Bell Labs in the mid-70s: the convergence was getting USG + PWB + (others) back together, synchronized around Edition 7, and the UNIX/TS 1.0, PWB/UNIX 2.0, System III, 4.0, and System V stream. (Of course, this was at the same time as Lab 127 was off doing Edition 8 & later...:-) 3) I'd suggest that XENIX divergence was another major one. 4) The BSD/System V split is at least the 3rd; note that many vendors already offer merged versions, so the split is not as bad as it might be. 5) The mutation/selection cycle is more like 6-8 years, although it's fuzzy, because it's clear that it's starting to happen long before it's finished. None of this is new: the battles inside BTL amongst UNIX variants (+ MERT, too) were pretty fierce, and for all of the same reasons: a) Take UNIX because it's at least close to what you need. b) Modify it because it is'nt 100% what you really need. c) Lobby like crazy to get your goodies accepted as part of the next standard version, so YOU don't have to continually retrofit your necessary changes into every new version, and so you don't get somebody else getting their [similar, but not as good as yours] feature in there, causing you to have to change... The fundamentals of this game haven't changed much in 10+ years, just the size of the playing field and the number of players :-) -- -john mashey DISCLAIMER:UUCP: {ames,decwrl,prls,pyramid}!mips!mash OR mash@mips.com DDD: 408-991-0253 or 408-720-1700, x253 USPS: MIPS Computer Systems, 930 E.
