Mac OS X Hacks
I am starting to go through O'Reilly's Mac OS X Hacks to do a review for the Chicago Perl Mongers.
So far so good. :)
Aside from some trouble getting a couple of perl modules compiled to run the examples, there are some great tricks in here. My G4 is very happy. ;)
UPDATE: I compiled perl 5.8.0 on my G4 and everything is peachy-keen now.
