QNX When Research In Motion unveiled its BlackBerry Playbook tablet on Monday, including the new QNX-based operating system it runs, I already speculated that it would probably make its way onto RIM's smartphones as well. RIM has now confirmed this suspicion.

The first thing I'd do in building any desktop operating system (if I had the skills) was to use QNX as a base. Fully transparent distributed computing, a true microkernel (none of that monolithic crap), a super-efficient and tiny (in all senses of the word) fully accelerated display server, self-healing and self-recovery in all layers and components of the system...

It's a piece of genius. Nothing comes even CLOSE - certainly not hodgepodges like Windows, Linux, and Mac OS X.

They have lots of nice optimizations in place to allow quick communication between kernel modules.

I imagine that QNX is the only successful micro-kernel OS out there.

VxWorks does quite well afaik and is a micro kernel too. Micro kernels in general are found in embedded computers anyway, because size and modularity are pretty key in that field.

Not quite right. SymbianOS has some success around the world, too, and if I remember well it's based on a microkernel called EKA2...

Yes, where would AmigaOS be nowadays, if Gateway did not screw the deal with QNX in 1998 :-( ... it would simply be power of QNX and brand power of Amiga (still good sounding brand back in 1998).

My point exactly, but ohno, better skip it for Linux, because, it's like, Linux!!! ...

Never mind AmigaDE (rather Tao-groups Elate and nothing more I suppose) which was just 100% retarded unless it actually _RAN_ on something Amiga.

Isn't QNX a major player in the embedded space (machinery, aerospace, etc, where there is zero fault tolerance) as well?

And yes, QNX and Symbian are two great examples of highly successful micro kernel OS's. Also, MacOS and iOS are based on the Mach micro kernel, and employ at least partial micro kernel design.

People often think that since Linux won over the failed (so far) Hurd project, and that Minix was only an academic OS, that the debate between monolithic kernels and micro kernels was over, and monolithic won.

But obviously that is not the case. Both have been successful.

What we in the business class "close but no Amiga", with two very different meanings.

#1: Sadly everything come short to the Amiga as we remember it.

#2: Amiga by all definitions of successful isn't ;)

We lend the concept to the quantum physics guys.
