On a tangent this makes me feel old. Unix, wasn't that solaris, aix, ... ?
Today I learned: Unix now is Linux and free bsd.
Get me right, this sounds good, great, actually. Still, it amazes me.

- AIX is Unix from IBM - A/UX is Unix from Apple. - They’re both AT&T System V with gratuitous changes. - Then there’s HP-UX which is HP’s version of System V with gratuitous changes. - DEC calls its system ULTRIX. - DGUX is Data General’s. - And don’t forget Xenix—that’s from SCO.
So if we want to talk about the most popular POSIX compatible systems today that are free we're left with the different kinds of BSDs and Linux OS. I also mentioned MacOS in the article, in relation to CoreAudio, but decided to leave it out as its design can't be inspected and compared properly. And also it's not a very popular OS amongst my readership and the world in general.
There's also the part where writing about it is not super interesting, because it mostly just works like it should.
And the binary compatibility of GNU/Linux, the interchangeability of suse, debian/ubuntu, red hat, keeps the promise that posix gave.
Which leads to the tangential point: a new generation which is growing up with "unix? That's Linux, right? Oh, and free bsd..."
Great, great article, btw
Arguably, this is sort of true today, adding MacOS to the mix. With Oracle Solaris discontinued, and Oracle Linux being where the work is at, plus a bit of IBM AIX and HP-UX used in some companies server but less common. That's mostly where the POSIX/Unix-like landscape is at today.
