I use hpux everyday. Mostly it still runs what it needs to run and the hardware for the most part is a tank so you don’t have to think about it.
When it breaks it’s the most infuriating thing in the world. All the hardware is bespoke and obsolete, old unix is maddening coming from modern Linux, it’s a nightmare but kind of fun at the same time. My only hope that HP will open source it at the end of the year.
There are a lot of hobby Unix-like OS’s however. I don’t see the point in most of them, but still.
You also forgot macOS. It’s a shitty “UNIX-certified” OS though.
In a sense, NextStep is the only one of the old Unix vendors to still have a significant install base.
I spent so much time working with Solaris, in a weird way I kinda miss it
SerenityOS has some relevance and its new.
While much of the Unix family has died, (especially in the System V family) there is an old one surviving and a few new additions being added.
Solaris is still alive, and from it was forked illumos. Meanwhile BSD has spawned its own family made up of FreeBSD, OpenBSD, NetBSD, and DragonFlyBSD, but also MacOS and Playstation. Other systems that appeared without any prior history like Linux include Redox OS and SerenityOS.
With that being said, the Unix family has noticeably shrunk, and the System V family is very much in danger of going extinct, with only the Solaris branch looking like it will survive the next year. If the System V family goes extinct, it would make the BSD family the only surviving branch descended from the original Unix.
Oh, and Minix still exists.
I watch a lot of videos to this day from Bryan Cantrill (Oxide computer) and he’s got some wild stories about the forking of illumos and how difficult it was to essentially “save” Solaris. His company uses their own illumos based distro called heliOS on their oxide computer rack.
SCO crashed and burned in part because they tried to sue multiple Linux providers claiming that they owned all the rights to certain pieces of code that they’d contractually leased from IBM, and that IBM giving code to Linux distributors violated the terms of their agreement with IBM. It was a lawsuit that dragged on for over a decade and a half–I think that it’s still going–and it’s bled SCO of tens of millions of dollars ,esp. since they’ve lost nearly every single claim they’ve made.
SCO Unix was mostly dead before then (not fully dead, just smelled like it). They were never the most popular Unix vendor to begin with. Caldera–a commercial Linux distro–had bought them out, and that’s when the legal trouble started.
All those old vendors tended to have one specific thing they were really good at. IIRC, the thing for SCO was that they could load up hundreds of users on a single box on 1990s hardware. No small feat when the traditional Unix model needs to
fork()a process for login/shell/whatever.It’s been a long time since I worked on that case, and I only did a very small part working on the discovery documents, so I’ve forgotten a lot, and had a lot of details a little confused. :)
It sounds like it was probably one of the seminal patent troll cases.
Copyright, yes. And a lot of this is corporate history rather than the legal portion.
SCO always reminds me of this:
The only one of these I never used was AIX. My first unix was Unixware.
Good, almost all of them were horrible, like AIX.
AIX is still alive and kicking if anyone still wants that “Linux but on hard mode” experience.
Where BeOS?
…beOS wasn’t really a POSIX system, but NeXTstep might fit alongside the others…
NeXTSTEP (and therefore, modern macOS) is a BSD.
Irix is missing. It was quite cool at the time. (Well, its desktop was).
Redox OS is a little baby sprout of grass on the very right
I don’t think that’s a good fit there, Redox OS is 10 years old and has yet to go stable. In the same timespan in the 90s, Linux managed to carve out a notable portion of server market share. I am not going to Tanenbaum myself and claim it’s never going to go anywhere but as is, Redox is more like the one who didn’t show up because they are still in their moms basement.
Actually Solaris is still squirming while the first shovels of dirt are being heaped on.
No love for temple os 😢
Temple OS wasn’t Unix-like.
Also it gets way too much attention as is IMO. Its the only hobby OS project people know about, purely because 4chan turned its mentally ill creator into a meme.
I didn’t realize the pattern
OP rewrite this meme…right now! TempleOS or ban.
Out of all those I only ever used Solaris and the most polite thing I can say is: I have no nostalgia for that time.
Well there is also macos
Is that open source?
Parts of it, yes. Not the components that make macOS a macOS though (AFAIK).
Which is BSD with a paint job and kiddy gloves
Well there are BSD components in there, but much of the kernel comes from Mach.
