[An aside: I’m not sure exactly when I became enough of a graybeard to remember as current events things which are now discussed as history. It’s really disturbing that an article from almost a decade ago talks about events seven years earlier than that, and I remember them happening! To me, the real graybeards are the guys that created UNIX and C to begin with. Me? I’m part of the second or third UNIX generation, at best. Sigh…]
Anyway, Bill and Lynne Jolitz created the first free, open-source UNIX that ran on x86 chips. Coherent was around before that, and I think SCO UNIX was available for x86 at the same time. SCO wasn’t evil then, just expensive. In those days, you had to lay down some serious jing to get UNIX on your PC. Minix was available for free, but Tannenbaum held firm that Minix should teach principles rather than be a production OS, so he favor pedagogical value over functionality. Consequently, Minix wasn’t a full UNIX implementation. (At least at that time. It might be now.)
Just contemplate the hubris of two programmers deciding that they would create their own operating system, to be UNIX, but fixing the flaws, hacks, and workarounds that had built up over more than a decade. Not only that, but they would choose to give it away for the cost of floppies! And not only that, but they would build it for a processor that serious UNIX people sneered at. Most impressive of all, they succeeded. 386BSD was a technically superior, well-architected version of UNIX for commodity hardware. The Jolitzes extrapolated Intel’s growth curve and rapid product cycles and saw that x86 processors would advance far faster than the technically superior RISC chips.
At various times, I ran Minix, 386BSD, and SCO UNIX on my PC well before I even heard of Linux. Each of them had the field before Linus even made his 0.1 release.
So why is Linux everywhere, and we only hear about 386BSD in historical contexts? There is exactly one answer, and it’s what Eric Raymond was really talking about in The Cathedral and the Bazaar. TCatB has been seen mostly as an argument for open-source versus commercial software, but what Raymond saw was that the real competition comes down to an open contribution model versus closed contributions. Linus’ promiscuous contribution policy simply let Linux out-evolve 386BSD. More contributors meant more drivers, more bug fixes, more enhancements… more ideas, ultimately. Two people, no matter how talented, cannot outcode thousands of Linux contributors. The best programmers are 10 times more productive than the average, and I would rate Bill and Lynne among the very best. But, as of last April, the Linux Foundation reported that more than 3,600 people had contributed to the kernel alone.
Iteration is one of the fundamental dynamics. Iteration facilitates adaptation, and adaptation wins competition. History is littered with the carcasses of "superior" contenders that simply didn’t adapt as fast as their victorious challengers.
