Matt Gallagher has an awesome collection of articles over at his blog, Cocoa
with Love. If you want to know the deep secrets behind Cocoa,
you will love browsing the post archives. He covers the gamut from Quartz, Core
Data, command line tricks, Audio, and so much more. Some of my favorite posts
he’s done are on core data performance, future proofing iOS
applications, minimalist cocoa programming, and how
malloc works on OSX.
Budget a long time to curl up next to the fire with your iPad. You’ll be lost
in this site for hours.
