Some rantings about code and an introduction to using ReactiveCocoa to solve all of the problems currently facing mankind—a phrase I only use somewhat facetiously because if software really is taking over the world then better software can, in a very real way, lead to a better world, assuming you’re not writing software for a doomsday device, in which case you should go ahead and write terrible software—but mostly focusing on writing reactive user interfaces because that’s nice and demoable.
