javascript book or tutorial?
I spent the first half of my carre (three years) in QA - partly doing some qa automation in python. I then spent the second half of my career working mostly in the DB world (python scripting and sql-server with some java mixed in). Now I'm working with Ruby on Rails and finding my lack of knowledge with javascript to be unbearable.

I'm sure most of you learned javascript by just mucking around/ working with it but I need something to prime the pump and at least get me in a position to write some simple JS and be able to understand what's happening with some of the more complex stuff.
