RE: Kernel Hacking (i tried not to make it lame)
I think Yahoo! is using still on 2.2.8. Don't let your imagination run away with you. :) Ok, ok. I just tried to say that there are still 2.2.8 users around with Yahoo! as an example. :-) Kees Jan You are only young once, but you can stay immature all your life.

Anyway, we rarely run the standard network services on them. And yes, we do have some 2.1.5 boxes kicking around still. I believe the number of 4.x boxes has finally passed the number of 2.2.x boxes, about a week or two ago.

On the other hand, the Daemon book (McKusick et al.) still has some fairly relevant sections (some of part 2, about half of part 3 and most of part 4), and does a good job of demystifying the kernel on a psychological level, i.e. teaching you that most of it really isn't deep voodoo and you can understand it if you try. In my experience, this psychological block is a much bigger obstacle to overcome than actual technical complexity.

I still think a really neat source for kernel hacking is Chuck Cranor's PhD thesis. He describes the kernel equivalent of open-heart surgery: replacing the old VM with a new one, while keep the kernel alive.

I'd imagine that just upgrading machines to recent versions of FreeBSD
would be just as easy as trying to push out that kind of update.
I'd encourage all others who are looking for softupdates in 2.2.8 to
just upgrade to 4.2-{RELEASE,STABLE}.

For example, Tannenbaum's or something like this. The 4.4BSD book goes into details expecting that you have the high-level knowledge of things, so without that knowledge it would be very difficult to read. Another prerequisite would be a book on general Unix systems programming, and by the same reason: reading about how things are implemented is much easier if you already know what these things being implemented are. -SB To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

so you mean like take one section at a time? like device drivers, smp etc? whatever catches my interest? ok i see just like programming when you got something big break it into parts, and wow can't belive the author of a great book and a core team member answered my question in less than an hour, try getting that from another OS :-) thanks greg! -Arthur To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
