It's also kinda a pile of garbage. But so is everything else... (actually in many ways it was a lot better than some others, but that's beside the point here).

It's also kinda a pile of garbage. But so is everything else... (actually in many ways it was a lot better than some others, but that's beside the point here). Part of my job at Apple was simply to cache and organize things locally for our team in a way that made sense to us. Every team is going to want to do this differently. Find good abstractions that are generic enough to let people do with them as they please. Don't force your model down my throat, I'll probably just gag it up and come after you instead. The issues at Apple stem from the top. Replacing Radar alone solves nothing.
