After the forged "QNX for sale" posting in various conferences, I have to
wonder if this posting is a deliberate attempt at flame bait, but all the
same, I'll ask the obvious question.
"Best at what?"
Every Os has a different mix of strengths and weaknesses, features which
were deliberately added to address specific application needs. In the case
of QNX, a microkernel architecture, realtime, certified POSIX compliance,
network transparent distributed processing, and fault tolerant networking
are some attributes that differentiate it from Linux and 386BSD.
In the case of 386BSD and Linux, attributes such as being free and full source
being available differentiate it from QNX.
As to which is best, you have to look at your application and see what
it needs most, and then choose based on that. After all, most of us
don't run operating systems just for the fun of it. The OS is usually
part of the environment (which includes the hardware) necessary to
support the applications we need to run.
