The Node Beginner Book

I've read through this guide before, and it's okay, but it's not really all that good at defining best practices, and in fact in some places the code isn't very good, but Manuel fully admits this in a few places.
If you don't already know JavaScript, or only know a little, this is probably a good place to start, but if you're already fluent in JS and have used server-side JS a bit in the past (whether through Rhino, sm, v8, whatever), it's probably not a very useful guide. Unfortunately, there aren't a lot of good resources out there - the language is very new and the library of current and available knowledge is not very large.
I haven't checked out the Node Cookbook yet, but do plan to in the future. Until then, to really get a good knowledge of some of the APIs you still have to do a bit of trailblazing.
I think that really changed from back in the days when I wrote The Node Beginner Book. For example "Professional Node.js" has been published some weeks ago: http://www.amazon.com/Professional-Node-js-Building-Javascri...
Full disclosure: I did the technical editing for this book, thus I'm highly biased. However, it was a pleasure to receive the single chapters from Pedro Teixeira, the author. It really teached me a lot while working on them. I honestly think it is a wonderful book, and one that Node.js deserves now that it matures.

And seriously, before jumping into node one needs to know some javascript. Haverbeke's 'Eloquent Javascript' and Resig's 'Secrets of the JS Ninja' will provide a starting point. They're one of these rare books you thought 'boy, I wished it was longer...'.
'Up and Running with Node.js''s code aren't thoroughly polished yet (eg.chapter 2), but plenty people refined and posted them on StackOverflow.
