Raleigh, NC—Want to become a better programmer? Learning a new programming language will show you new ways of thinking, and new approaches to problem solving that will help you be a better programmer in any language. And what if you could learn the important lessons from seven different languages? You'd be unstoppable.

In Seven Languages in Seven Weeks (Pragmatic Bookshelf, $34.95) best-selling author Bruce A. Tate gives you a hands-on tour of Clojure, Haskell, Io, Prolog, Scala, Erlang, and Ruby. Bruce says, "The languages that I picked are not necessarily the best, but each one is unique, with something important to teach you." Bruce hits what's essential about each language and will help you learn how to learn new languages.

Among this group of seven, you'll explore the most critical programming models of our time. Learn the dynamic typing that makes Ruby, Python, and Perl so flexible and compelling. Understand the underlying prototype system that's at the heart of JavaScript. See how pattern matching in Prolog shaped the development of Scala and Erlang. Discover how pure functional programming in Haskell is different from the Lisp family of languages, including Clojure.

Explore the concurrency techniques that are quickly becoming the backbone of a new generation of Internet applications. Find out how to use Erlang's let-it-crash philosophy for building fault-tolerant systems. Understand the actor model that drives concurrency design in Io and Scala. Learn how Clojure uses versioning to solve some of the most difficult concurrency problems.

It's all here, all in one place. Use the concepts from one language to find creative solutions in another—or discover a language that may become one of your favorites.
