Dave Thomas is one of the best tech authors I have read (up there with Forrest M. Mims III)! Good tech authors can talk down to you without making you feel like an idiot. This book taught me just enough about ruby to be dangerous. I like how it's divided into two major sections to include a language/stdlib reference in back. It also concisely explains the ruby object system and I had to reread that part like six times. That section of the book is more like a mathematical expression of truth than an explanation but if you seek you will find. Incidentally I can't see a better way of explaining ruby's OOP so I have no criticism for this book. It's one of the few I have read cover to cover.
