This is not a spot. This is a book I’ve been leaving closed because of its cover… what a pity! This is the first book I’ve ever read that actually talks and explain object oriented in an easy and pleasant way. Most experienced programmers will find it not much useful, but for a newbie or an intermediate OO programmer this is a must read.
In case of doubt, just read it :) It will worth the time you’re going to spend. Definitely. And it’s also quite amusing sometimes!
