Did something change? Ooops ! Mea Culpa (shows what happens when you just grab text) I still stand by my basic arguement, though. As long as we have a market driven by simplistic enumeration of system "features" we're going to get bulky systems comprised of poorly integrated, hacked-on kludges to what once were a fairly elegant and simple systems (we could start all over again with . . say MACH, and in 5 years or less we'd have another, slightly different, gigantic mess) That is, UNLESS we can "sell" a new buzz-concept: the Reduced Feature Set System (All the advantages of RISC only now at the system level ! Build your OWN features quickly and easily through the simple combination of these basic features ! Prototype and test new software with speed and ease !) . . . naaah, it'll never work.

I read, > Looks like folks are now beginning to credit the development > of UNIX to Kernighan and Ritchie, but I thought the principal > investigators were *Thompson* and Ritchie. Did something change? The differences between Kernighan Ritchie Thompson are real but very subtle. We all look alike (middle aged with scruffy graying beards). Note these distinctions: -- Kernighan is slimmest, Ritchie middlest, Thompson heaviest in body build -- Ritchie got contacts a couple of years ago and so is the only current non-glasses wearer -- Thompson wouldn't touch netnews with a pole, Kernighan secretly gets misc.invest and misc.taxes mailed to him, Ritchie reads it more than is good for him and occasionally contributes -- Ritchie is the only one who has met five people who have appeared on David Letterman (Penn, Teller, Rob Pike, Mayor Koch, and the guy who raised the biggest hog in Ohio) -- Kernighan has written ten times as much readable prose as has Ritchie, Ritchie ten times as much as Thompson. It's tempting to say that the reverse proportions hold for code, but in fact Kernighan and Ritchie are more nearly tied and Thompson wipes us both out. Dennis

Did something change? From what I understand, Thompson and Ritchie wrote the Unix Kernel, mostly by themselves, up to V7 included (one did IO, the other the rest). But a crew of various colleagues of those two wrote most the of UNIX utilities; Bourne the shell, Kernighan Weinberger coded AWK (I think mostly Kernighan) with design help from Aho, the late Ossanna [tn]roff, Bourne the V7 shell, Kernighan again produced ditroff and pic, Ritchie himself the first C compiler, Johnson the pcc, Lesk a number of text processing thingies, and many others that I omit for brevity. Kernighan, Ritchie (and Pike) are the names most frequently associated with Unix because they wrote the C language book and the Unix environment book on which most UNIX programmers start. Therefore they have enjoyed more public exposure than Thompson, which (I seem to remember) arguably considers UNIX mostly a development system for chess machines... :-) As far I can see, the fundamental Unix flavour is from Thompson, the fundamental C flavour is from Ritchie. -- Piercarlo Grandi | ARPA: pcg%uk.ac.aber.cs@nsfnet-relay.ac.uk Dept of CS, UCW Aberystwyth | UUCP: ...!mcsun!ukc!aber-cs!pcg Penglais, Aberystwyth SY23 3BZ, UK | INET: pcg@cs.aber.ac.uk

He said, "I used to work for Bell Labs out in New Jersey. Kernighan and Ritchie are flakes who run around outside in sandals and no socks in the middle of the winter." It's impossible to represent his tone of voice, but it was obvious he thought he was giving me the last word on the usefulness of c as a programming language. dan herrick herrickd@astro.pc.ab.com

Actually if they had the resources, I believe that today's processes would make this part fast enough to be useful, and salable in a niche market for doing object oriented stuff. I confess that I see no hope there will be unused resources in Intel's future, so I'm not holding my breath. The concepts were way ahead of their time, though, in both advance of the market, and advance of the processes which would make the chip reasonably fast. -- bill davidsen (davidsen@crdos1.crd.GE.COM -or- uunet!crdgw1!crdos1!davidsen) VMS is a text-only adventure game.

Researchers probably need not apply - although several parallel computer companies have made money off the parallel research market, the type of problems that are attacked by parallelism tend to have more money thrown at them than the type of problems solved by objects. (Disprove by showing a budget breakdown for the NSF and other funders, with funds available for machine purchase.) Security? Maybe - but security, at least, has moved away from complexity in the hardware, and towards secure OSes running on stock hardware. Fault tolerant/reliable systems? Maybe - but Tandem's recent UNIX based systems may indicate the trend for FT to run on stock hardware as well. Although, to take the other point of view - the Intel i960 really very much is a descendant of the 432. With the various problems that led to poor performance fixed. -- Andy Glew, a-glew@uiuc.edu [get ph nameserver from uxc.cso.uiuc.edu:net/qi]

How is the Touchstone Delta _qualitatively_ different than the
original Cosmic Cube by Sietz et al ? It certainly is faster, and has
more processors (and snazzier ones at that) .... but the other
machines listed seem to be attempts to chose seminal machines ....
else one would expect the S/360 to be a 3090 (or whatever), the XMP
with a YMP, etc.

I am pleased that he has taken the time to post a correction. Note that in Kernighan and Pike's "The Unix Programming Environment" the authors state that the first version of Unix was written in 1969 by "Ken Thompson, with ideas and support from Rudd Canaday, Doug McIlroy, and Dennis Ritchie" and that "In 1973 Ritchie and Thompson rewrote the Unix kernel in C..."
