Understanding OS X Kernel Internals

jglidell writes "The OS X kernel has been in the news alot this past year, whether it's why its slow, Mach/micro-kernel makes it bad, it's going closed source and what not. Amit Singh has put up a new presentation on the innards of OS X. It does a pretty good job of summing up the OS X kernel architecture, and has some pretty detailed diagrams... for instance they show that there are so many process/threads layers in OS X. So if you are in the mood for doing some OS studying then head over."

"alot" isn't a word! It's "a lot."

I also get kinda pissed off because lotsa people write it that way.

I think the problem is that they're not as skilled in writing english as they are in writing PERL.

I've seen slashcode.

I think the problem is that they're exactly as skilled in writing english as they are in writing PERL.

Nope, it's still gibberish.

whether it's why it's slow

Well... why is it slow?

Mach/micro-kernel makes it bad

Debating the pros and cons of Mach is a valid topic, but a phrase like this is so vague that it's meaningless.

it's going closed source

OK, that one's intelligible. But then we come across gems like this:

for instance they show that there are so many process/threads layers in OS X.

A small request for submitters: Take a minute to actually proof-read your summary. I'm not even talking about simple typos, or the correct use of "you're/your" - those look ugly, but most of the time people can still figure out what you meant. Just ask yourself: will these words make sense to a moderately intelligent English speaker who's not on a meth bender?
