Free Coding Tutorials by Google! (MySQL, AJax, and more)

I am a CS major who really likes to program (kinda goes with the whole CS major I suppose) but there are a few areas where I know I am deficient, namely web programming and database stuff.

I have dabbled in both but never really looked very deeply into either one, then just today I saw a link on Digg directing me to this: http://code.google.com/edu/

So far it looks pretty interesting, but I have only looked at the MySQL page. I just wanted to share this and this forum looked as good as any other.
