And sgi had irix, sco, let's not talk about sco, and even windows nt and os/2 claimed a posix layer, and I'm old enough to have used a couple of them, always "configure; make; make install"-ing GNU in top to get true interoperability, lol 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

> "unix? That's Linux, right? Oh, and free bsd..." 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.
