Rather than taking up space in my crowded bookmarks folder, I thought I'd just blog these two posts and reference them from here.
Sean Moore has posted an Actionscript 2.0 to Actionscript 3.0 migration cheatsheet which I may find very useful in the near future. He's also got a lot of other cheatsheets on his site. If you haven't gotten a chance to check them out I recommend you do.

Also, Alex Ulhmann has updated his distortion effects component. I made some modifications to the first version of his component to create a iTunes-type image scroller in Flex (sorry, it's not online... yet). I'm looking forward to seeing what he's done to improve it and what new things I can do with it.
