Dear Dev Juice, I'm having an issue with UIView animations, that I'm struggling to describe in keywords, so I can't find anything helpful with Google. The problem is that I can't seem to work out how to make a UIButton move relative to the bottom of the parent view, as I shrink the parent view....

Dear Aunt TUAW, I'm in the Mac Developer program and I'd really like to be able to install Lion on my MacBook Air as a second OS. What are the best strategies to do this? Is it worth going out and buying a second SSD drive and swapping that out with my primary Snow Leopard system? Thanks for...
