Sure, the title sounds kinda nasty, but it's not.
OK. I gotta admit, the new oreilly "Head-First" book series looks awesome. Thanks to Oleg for pointing to it.
And yeah, the sample chapters do look amazingly as if Rory had done all the artwork using his tablet PC and imagination. Nice work. Check out the head-first patterns book chapter about the decorator pattern or the other samples. It's pretty cool.
Speaking of books, Moshe Eshel points to several online book resources. I personally am subscribed to safari books online which is pretty cool.
