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.

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.


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.

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


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).

POSIX is a second-class citizen to the Be API, and as such, most of the POSIX API that Haiku supports is just "bolted" on top of Haiku to provide a certain level of compatability with non-native code. In fact, a lot of the POSIX compatability has only been implemented in the last few years for this exact reason.

BeOS, although it had a certain degree of POSIX compatability, was nothing compared to what Haiku has gained in the last few years

I knew that was going to be the answer.

The Be API is NOT the kernel API. It is a user space library which sits on top of the kernel API. Using the Be API on Haiku is the same as using Qt on Linux. Neither invalidates the fact that the kernel API is POSIX.
