Very nice (it even has an +ORC quote in it)!

I'd really like to see more people posting quality links like this. So please everyone, if you see any good articles (or other types of resources) about reversing/cracking/low-level stuff like this anywhere, please don't hesitate to share them with the rest of us by posting them here (if in doubt, simply use the off-topic forum)!
