Developers the world over talk about

Programming Ruby and the Ruby language. . .

“Ruby is a wonderfully powerful and useful language, and whenever I’m working

with it, this book is at my side.”

Martin Fowler , Chief Scientist, ThoughtWorks

“If your world revolves around Java, as mine did, then you need this outstanding book

to learn all the wonderful things you’re missing. There’s just one catch: you’ll be

spoiled from then on. Indeed, after reading just a few pages of Programming Ruby ,

programming in any language other than Ruby will feel like you’re pushing rope.”

Mike Clark , Author and Consultant

“Ruby is smart, elegant, and fun, and it deserves a book that’s smart, elegant, and fun.

The ﬁrst edition of Programming Ruby was such a book; the second edition is even

better.”

James Britt , Administrator, http://ruby-doc.org

“The best reason to learn a new programming language is to learn to think differently.

The best way to learn to think the Ruby way is to read Programming Ruby . Several

years ago, with the ﬁrst edition of this book, I did just that. Since then, I’ve had a

constant stream of enjoyable Ruby programming experiences. This is due in no

insigniﬁcant part to the quality of the source from which I learned the language. I’m

not the only person I’ve heard say that every language should have a book like this.”

Chad Fowler , Codirector, Ruby Central, Inc.

“The PickAxe got me started on Ruby. It is still the ﬁrst book I turn to.”

Ryan Davis , Founder, Seattle.rb

“This book changed my life. Sounds rather clichéd, but it’s the truth. After six years

and 300,000 lines of Java code, I needed a change. That change occurred upon reading

the ﬁrst edition of this book. With the support of a solid community and ever-growing

foundation of superb libraries, I founded a company that largely proﬁts from applying

Ruby to solve real-world problems. Ruby is ready for prime time, and this new

version of the PickAxe will show a waiting world what a gem Ruby really is.”

Rich Kilmer , President and CEO, InfoEther LLC

“The ﬁrst edition of PickAxe has been a desk-side companion for years. The second

edition will be an eagerly awaited replacement.”

Tom Enebo , JRuby Developer

“The ﬁrst edition of Programming Ruby brought about no less than the introduction of

Ruby on a large scale outside of Japan, in the process becoming the de facto standard

published language reference and an oft-cited model of clear, effective technical

writing. The appearance of the second, expanded edition is exciting for Ruby

programmers around the world and will no doubt attract a fresh wave of newcomers to

this elegant, versatile language.”

David A. Black, Ph.D. , Codirector, Ruby Central, Inc.

“Ruby is my deﬁnite choice for all scripting and prototyping issues, and this book will

help you to discover its usefulness as well as its beauty. Apart from that, it’s really fun

to read!”

Robert Klemme

“I bought the ﬁrst edition of this book the day it was released and had a fantastic time

using it to learn Ruby. I eventually bought a second copy to keep at home. But Ruby

has changed since then. I’m delighted that this second edition of Programming Ruby

is available to help a new round of programmers learn about this fantastic, beautiful

language. And it’s not just good news for Ruby newbies, of course—like me, most

Ruby developers will want a copy (no, make that two) so that all of the details about

today’s Ruby will be close at hand.”

Glenn Vanderburg , Software Architect, Countrywide Financial

“Ruby is one of those great languages that takes an afternoon to start using and years

(maybe a lifetime) to master. In C, I’m always having to work around the limitations

of the language; in Ruby, I’m always discovering a neater, cleaner, more efﬁcient way

to do things. Programming Ruby is the essential reference to the Ruby language. More

than just teaching you the syntax, it teaches you the spirit and the feel of the language.”

Ben Giddings

“Confucius said, “What you hear, you forget.” He also said, “What you do you

understand.” But it’s not easy to actually “do” things unless you’re using a great

language with strength in quick and clean prototyping. In my case, this language is

Ruby! Thank you!”
