Design Patterns For Dummies

Like many other programmers, after reading the seminal Design Patterns by the GoF, I was under the charm, while at the same time quite confused by some of the patterns. I had to get an other book to polish the rough edges. I got this book, and quite frankly I only read one chapter, the one about Flyweights. Now if like me you work in the video game industry, you know full well how important Flyweights are in game dev, and one of the patterns you probably know, like me, in depth. I couldn't believe what I was reading. This chapter is not merely misleading, it is dead wrong. The code example doesn't show at all what a Flyweight is. Now the damage was done: how can I learn from patterns I have difficulties with, if that one I know full well is so wrong? I returned the book, did some research and got the one from Christopher Lasater instead. If you want to understand the most cryptic parts of the GoF book, avoid that dummy book and go straight to the Lasater one.
