BeOS & Derivatives "Ultimately, Haiku represents a different way of viewing your personal computer. If you think that software shouldn't be riddled with bugs and incompatibilities and inefficiencies, if you hate being forced to swap out your hardware and software every few years because 'upgrades' have rendered them obsolete, and if you find that the idea of using an operating system that's fast, responsive, and simple is refreshingly novel and appealing, then maybe, just maybe, Haiku is for you." What fascinates me the most is that Haiku's not working on a tablet version. How delightfully quaint.

Hang on a minute. If you're talking kernels, both Linux and Haiku are POSIX systems. POSIX is codified UNIX.


While Haiku does support POSIX, it is not a "POSIX system", and not a *NIX. POSIX is simply an addition, not the base for it.

After all, Windows supports POSIX too, if you want it. Does that make it a "POSIX system" as well?

Correct me if I'm totally wrong here, but POSIX on Haiku is a first-class, and in many cases the only, API[1]. The Haiku kernel does not have Haiku-native equivalent of open() or read(), as a very simple example.

No, and you're making my point for me here. Linux is no more "based around a kernel that was originally designed for servers" than Haiku is.

[1]: kernel API. You can, of course, build non-POSIX APIs on top of it, which is obviously exactly what OSes like Haiku do, but the POSIX API is still at the bottom of the abstraction.

Hi,

"While Haiku does support POSIX, it is not a "POSIX system", and not a *NIX. POSIX is simply an addition, not the base for it.

Ok, you're wrong. The primary/native API used by Haiku is the same API that was used for BeOS. This API is described here: http://www.haiku-os.org/legacy-docs/bebook/index.html

Notice that it looks nothing like POSIX.

I'm not sure how well integrated their POSIX API actually is; but I also doubt it matters. Haiku/BeOS is different (lots of message passing and multiple threads) and applications designed for POSIX (that don't use message passing, etc) will always be a poor fit regardless of how well implemented the POSIX API is.

Unfortunately, for a new OS there's always a "chicken and egg" problem - it's hard to attract developers when there's no applications and hard to get applications without developers. I'd assume that the only reason they bothered with POSIX at all was to break this "chicken and egg" problem (by making it easy to port "better than nothing" applications from elsewhere).

Any operating system that is able to pass the POSIX certification tests, regardless in what form is a POSIX system.

Windows POSIX subsystem (Interix), althought not certified, is compatible with POSIX.1-1990.
