I hate absurdly long variable names like this: static const NSTimeInterval NYTArticleViewControllerNavigationFadeAnimationDuration = 0.3; I feel like if your naming convention forces you to have variable names over 50 letters long, there is a problem.
My only gripe about developing on a 13" MBP is not being able to have 2 buffers side by side without wrapping the snot out of half the lines.
