Praise for Head First Design Patterns

I received the book yesterday and started to read it on the way home... and I couldnt stop. I took it to the gym and I expect people saw me smiling a lot while I was exercising and reading. This is trs cool. It is fun, but they cover a lot of ground and they are right to the point. Im really impressed.

Head First Design Patterns manages to mix fun, belly-laughs, insight, technical depth, and great practical advice in one entertaining and thought-provoking read. Whether you are new to design patterns, or have been using them for years, you are sure to get something from visiting Objectville.

I feel like a thousand pounds of books have just been lifted off of my head.

This book is close to perfect, because of the way it combines expertise and readability. It speaks with authority and it reads beautifully. Its one of the very few software books Ive ever read that strikes me as indispensable. (Id put maybe 10 books in this category, at the outside.)

David Gelernter, Professor of Computer Science, Yale University, and author of Mirror Worlds and Machine Beauty

A Nose Dive into the realm of patterns, a land where complex things become simple, but where simple things can also become complex. I can think of no better tour guides than Eric and Elisabeth.

I laughed, I cried, it moved me.

Daniel Steinberg, Editor-in-Chief, java.net

My first reaction was to roll on the floor laughing. After I picked myself up, I realized that not only is the book technically accurate, it is the easiest-to-understand introduction to design patterns that I have seen.

Dr. Timothy A. Budd, Associate Professor of Computer Science at Oregon State University and author of more than a dozen books, including C++ for Java Programmers

Jerry Rice runs patterns better than any receiver in the NFL, but Eric and Elisabeth have out run him. Seriously...this is one of the funniest and smartest books on software design Ive ever read.

Aaron LaBerge, SVP Technology & Product Development, ESPN

Theres an old saying in the computer and videogame businesswell, it cant be that old because the discipline is not all that oldand it goes something like this: Design is Life. Whats particularly curious about this phrase is that even today almost no one who works at the craft of creating electronic games can agree on what it means to design a game. Is the designer a software engineer? An art director? A storyteller? An architect or a builder? A pitch person or a visionary? Can an individual indeed be in part all of these? And most importantly, who the %$!#&* cares?

It has been said that the designed by credit in interactive entertainment is akin to the directed by credit in filmmaking, which in fact allows it to share DNA with perhaps the single most controversial, overstated, and too often entirely lacking in humility credit grab ever propagated on commercial art. Good company, eh? Yet if Design is Life, then perhaps it is time we spent some quality cycles thinking about what it is.

Eric Freeman and Elisabeth Robson have intrepidly volunteered to look behind the code curtain for us in Head First Design Patterns . Im not sure either of them cares all that much about the PlayStation or X-Box, nor should they. Yet they do address the notion of design at a significantly honest level such that anyone looking for ego reinforcement of his or her own brilliant auteurship is best advised not to go digging here where truth is stunningly revealed. Sophists and circus barkers need not apply. Next-generation literati, please come equipped with a pencil.

Just the right tone for the geeked-out, casual-cool guru coder in all of us. The right reference for practical development strategiesgets my brain going without having to slog through a bunch of tired, stale professor-speak.

Travis Kalanick, CEO and cofounder of Uber and Member of the MIT TR100

This book combines good humor, great examples, and in-depth knowledge of Design Patterns in such a way that makes learning fun. Being in the entertainment technology industry, I am intrigued by the Hollywood Principle and the home theater Facade Pattern, to name a few. The understanding of Design Patterns not only helps us create reusable and maintainable quality software, but also helps sharpen our problem-solving skills across all problem domains. This book is a must-read for all computer professionals and students.

Head First HTML and CSS is a thoroughly modern introduction to forward-looking practices in web page markup and presentation. It correctly anticipates readers puzzlements and handles them just in time. The highly graphic and incremental approach precisely mimics the best way to learn this stuff: make a small change and see it in the browser to understand what each new item means.
