The Solaris developers' holy trinity is complete!
Last Friday (August 4), I received my copies of the second edition of Solaris Internals by Jim Mauro and Richard McDougall, and Solaris Performance and Tools by Jim, Richard, and Brendan Gregg. I've only had a chance to skim them so far (although I did help review part of Solaris Internals), and I have to say: I'm impressed. So much so that I'd go as far to say that these two books complete the Solaris and the OpenSolaris developers' holy trinity.
What's the third book? With all humilty, I'd say it's Solaris Systems Programming, by yours truely. If you're serious about developing software--be it userland or kernel--for (Open)Solaris, you need these books.
