Patrick Steger, Zühlke Engineering AG

The Well-Grounded Rubyist takes you from interested novice to proficient practitioner. It's a beautifully written tutorial that begins with the basic steps to get your first Ruby program up and running and goes on to explore sophisticated topics like callable objects, reflection, and threading The book concentrates on the language, preparing you for any way you may choose to use Ruby. Whether the topic is simple or tough, the book's easy-to-follow examples and explanations give you immediate confidence as you build your Ruby programming skills.

About the Technology

Interest in Ruby has exploded. Developers discovering this elegant, dynamic language quickly learn that Ruby is a powerful alternative to traditional static languages like Java or C++. It runs in most operating environments and can handle virtually any programming task you throw at it. Ruby code is clean and elegant. Best of all, Ruby is dynamic, which means that it's designed to react at runtime to changes in an application's environment or requirements.

About the book

The Well-Grounded Rubyist is a thoroughly revised and updated edition of the best-selling Ruby for Rails. In this new book, expert author David A. Black moves beyond Rails and presents a broader view of Ruby. It covers Ruby 1.9, and keeps the same sharp focus and clear writing that made Ruby for Rails stand out.

It's no wonder one reader commented: "The technical depth is just right to not distract beginners, yet detailed enough for more advanced readers."
