"I guess I need to support my assertion that Dr. Rashid wasn't the only person who worked on the Mach kernel"

Rick Rashid is still the one who is credited with developing the Mach multiprocessor operating system, which has been influential in the design of many modern operating systems and remains at the core of a number of commercial systems.
Of course most professors get some of the legwork done by their students in any research project.
That doesn't mean those students are credited with having invented or developed what was invented or developed.

Still doesn't explain your weird claim that:

"dalight: "The only University professor that I know who wrote a major operating system that enjoys any market share today is Linus Torvalds"

Does it?
You just keep lying and hope no one catches you out, don't you? Normal open source fanatic practice..

Ummm about Linus Torvalds being a professor like you claimed.. what university was that at again?

You don't have a clue what you are talking about do you?
You just keep making things up.

Still doesn't explain your weird claim that:

He's already corrected himself on this, and complained that you didn't notice his correction.

Either you can or won't read what is written by those responding to you.

I don't guess I care which.
