Holy shit, I grew up from a dropout waiter to an iOS dev via twitter circa 2009, and he always stood out. Literally 24 hours ago I remembered this via a rando shower thought, but couldn't remember his name. A little weird, but I was, young, innocent, and unusually starry-eyed worshipful of people who pulled off deep contributions like his ObjC safer code macros / preprocessor magic library, libextobjc(?)
