This book is great.

This book certiantly is not a crash course. I have been working through it in my spare time since I got it a couple of years ago. I have been taking my time because I was going through school when I got it and couldn't make time for it. Now seeing this article I should pick it back up again.

I suggest though that everybody resist the urge to find the answers rather than doing them yourself. It's quite rewarding when you figure things out. There isn't one way to do it.

The only complaint I have is that when you start getting into higher functions they recommend you not use the pieces you built up for performance reasons. Personally I would like to figure these out but perhaps that should be left for a later day.
