One of my early mentors was a former product person at Apollo in Mass. and was nice enough to tell me all sorts of war stories working there. I had known about Plan9 at the time, and from what he described to me about domain/OS it sounded like there was lots of overlap between the two from a high level design perspective at the least. I've always been keen to understand if domain/OS grew out of former Bell Labs folks, or how it got started. As an aside, he gifted me a whole bunch of marketing collateral from Apollo (from before the HQ acquisition) that i'd be happy to share if there is any historical value in that. At the time I was a video/special effects engineer are was amazed at how beneficial having something like domain/OS or Plan9 would have been for us, it felt we were basically trying to accomplish a lot of the same goals by duct taping a bunch of Irix and Linux systems together.

It would be news to me if there was overlap. I used apollos at my first job and hated them. Diskless and slow as molasses.

As I understood it, Domain/OS was more influenced by Multics and maybe the Pr1me machines than anything else. Plan 9 came from the Unix heritage (and thus had Multics as a grandparent, in a manner of speaking). If there was any connection at all, I suspect it was tenuous and more in the form of an indirect influence, such as an idea someone got from a paper or something like that. - Dan C.

I agree it was a wonderful intellectual playground for some very cool ideas. Some worked pretty well, but not all did. For example, as Larry said earlier today, the "twin'ed" or diskless nodes were awful (replace the S with C for what many of us think about them). But it got Sun to make them too and ended up being a great add-in disk business later. I refused at Masscomo and ended up losing war, even though the cost of a WS500 was less than a Sun2 with a disk, people bought Sun's diskless and then after they discovered they sucked, spent another 6K to buy a desk system for them (we lost for economics, but I was technically right - a.k.a. Cole's law of economics vs. sophisticated technology). Anyway, we (as a community) are better for having that system but other than the registry, I can think of little actual technology that we continue to use from Aegis.

The OSF/DCE's RPC system came from Apollo, as does the predecessor for the UUID layout still in use today (RFC 4122). Paul Leach brought both to the OSF, and as the Kerberos V5 Tech Lead, I worked with Paul, and used an early Internet-Draft spec of the OSF UUID and implemented it in e2fsprogs for labelling ext2/3/4 superblocks, and from there the infection vector spread to the GNOME project. When Paul brought both of those technologies to Microsoft when he went there after OSF went belly up. - Ted ^ permalink raw reply [flat|nested] 17+ messages in thread

I don't know when he left Apollo (or HP/Chelmsford after they bought it) for Microsoft, but it was before OSF died. That latter happened because Sun (Rob Gingell?) insisted OSF stop doing all development as the price of ending the Unix wars and joining everyone in opposing Redmond. We could no longer say OSF stood for Oppose Sun Forever. I liked that NCA could handle env vars in pathnames, which Locus also had IIRC. Domain also had "fat executables" similar to what Apple did when migrating across CPUs. And their build and source system was recreated as ClearCase.

That was the Domain Software Engineering Environment (DSEE). One of my fellow engineers in DEC's Software Development Methods & Tools group was Dave Leblang, He had been working on CMS (Code Management System), DEC's source code versioning system for VAX/VMS. At Apollo he developed DSEE, and he was a co-founder of Atria. CMS took many ideas from SCCS on the PWB. Apollo also did some early work in the field of CGI ray-tracing. They released the very impressive 4-minute film "Quest: A Long Ray's Journey into Night" in 1986. The ray-tracing was done by a network of 100 Apollo workstations and was revolutionary for its time. -Paul W. ^ permalink raw reply [flat|nested] 17+ messages in thread

Thanks Paul, I vaguely remember being told about this effort by my mentor which is what sparked my interest. At the time we were trying to optimally use all available CPU resources for rendering and while we did have working solutions it required lots of perl and shell. so the idea of CPU resources being available and shared as a foundational concept on the network was really interesting to me. I also seem to remember him telling me about working on the patriot missile system, although i am not certain if i am remembering correctly that this was something he did at apollo or at another company in the boston area. -pete -- Pete Wright pete@nomadlogic.org @nomadlogicLA ^ permalink raw reply [flat|nested] 17+ messages in thread
