For all of you following Scala, the first real book is out now! I just bought/ downloaded it, and it looks good. You can get it on the Artima website. Where do I get some time to actually read it. :-)
If you have plans to dive into Scala and you are new to Functional Programming (like I am), I’d recommend you to also learn Haskell to get a good foundation. At least I found that when reading Programming In Haskell, some Scala constructs started to make more sense to me.
