I read a chapter on writing API's. Nice chapter. Not to be sarcastic, but he does help us understand how to get around the limitation of not being able to create multiple constructors for a class. Coming from a Java background, that was one really confusing thing in ruby.
But for those who enjoy the book, I've already moved on to my next project: http://www.rubyproblems.com/
Couple of suggestions, if you had a one off membership fee (instead of $3 per solution), and a way of registering without using OpenID, I would have signed up/paid immediately.
