I don't think you can say a non-real-time operating system is
incorrectly designed.  It just has different goals.  

For example, A desktop operating system (especially multi-user
systems) try to be "fair" when allocating system resources.  An RTOS
tries to be "correct."  An RTOS has no qualms about starving a
philosopher, if that's what's required.

I haven't posted here for some time. I used to post quite regularly 
until the groups got swamped by flame wars and self appointed net cops. 
  I used to come here for a little pleasure, and to see if I could 
perhaps be of help to someone, but the recent influx of narrow minded 
bigots has taken all pleasure away from the experience. I still try to 
help, of course, but you can't sway a religious fanatic into believing 
there's more than one way to do things..

  There are many here who know me.  I have nearly 35 years experience as 
an engineer and designer. I have managed the systems division of a US 
corporation, consulted to Stoke Mandeville spinal injury unit, the VA 
rehab centre in Palo Alto, and the USAF, among others, and employed many 
engineers over the years in my own companies.

Within the last 2 years I've developed systems for military use which 
are under trials in the US. A 14 frame per second 4 image per frame, 
image processing system, based on an MSP430 ($600k in systems sold since 
shipping #1 last July). A non-intrusive scanning device which can detect 
tumours within 1cm of the skin surface before they reach pin head size, 
about to start clinical trials. And an adaptive pain suppression system, 
currently being trialled.  I did want to enter the DARPA autonomous UGV 
contest, but they only allowed US residents to play, and travel is a 
bitch these days. Not much I know, but I've had to fit spinal surgeries, 
and a pretty nasty bout of diverticulitis in between work. Hopefully 
I'll do better next year.

Call it what you will, at least I'm not hampered by a narrow mind.

I guess that has to be an American joke. It doesn't play in English.

I apologize for not having done the research before. You have indeed
made useful though irregular contributions to the group. In your
latest round, though (starting June 11) your very first word was
"Bullshit", and things have deteriorated from there.

We hadn't had a flame war here for some time, until the current one
was triggered by some particularly obnoxious top-poster/non-snipper.
You didn't start it, but you jumped right in calling those who
disagreed with you bigots, and adding further insult by expressing
agreement with something unspecified in the 145 lines which followed
your contribution.

Obviously. Well, I shall attempt rational discourse with religious
fanatics no longer. Top post all you like. Bye, now.

It is amazing how many posts one mis-spelling can cause.
