Mac is now UNIX (officially)
I know it has been blogged to death by now, but Mac OSX, my desktop OS of choice, is now officially a standard UNIX. Specifically to the UNIX 03 Product Standard. This confirms it conforms to Version 3 of the Single UNIX Specification. This makes Apple Inc. an official UNIX vendor along with all the other big boys.
On the serverside, I will stick with OpenBSD as my personal server OS of choice, with Solaris following close behind.
