Damn, I remember I worked through the whole damn thing some years ago when I read this article for the first time, and it didn't hold up to it's claim. I was actually contemplating to do a write-up, but it wasn't really important to me so I didn't. Seeing the same article re-appear on HN for the second time now I really wish that I did. Unfortunately I've forgotten the details by now.

If you ever do, post it! I'm sure it would be an interesting read
