Have you ever read the Head First Design Patterns book ?
If you haven't, you have to ! If you have, you have to re-read it again just for fun !
Jokes aside, I'd like to congratulate Eric Freeman, Elisabeth Freeman, Kathy Sierra and Bert Bates for this so wonderful book.
Honestly, after read this from book cover to cover, I realized how smart the authors are and how novice grasshopper I am.
For sure when you, authors, decide to get retired from Java world, (and I don't hope so shortly...) maybe when Bert can upgrade from his Subaru , you still will leave us a big legacy among with your wonderful books.
I'm really impressed about the graphic quality of the pictures and so detailed and simple explanations.
After read your wonderful book from cover to cover, with authority I can define you as Gang of Four (Eric, Elisabeth, Kathy and Bert ) once the book was created by a Computer Scientist from Yale University and Indiana University, Master Trainer for Sun Microsystems, Dedicade-Long stint in artificial intelligence ...., well, there are so many skills that I could full fill this page.
Very nice job guys. Many congrats and if this so kind words can massage your egos, here's my thoughts.
