Ruby Under a Microscope

Praise

“Nearly every Ruby expert will benefit from knowing so much about how the language and runtime operate.”
—Dr. Dobb’s 

“Many people have dug into the Ruby source code, but few make it back out and tell the tale as elegantly as Pat does in Ruby Under a Microscope! I particularly love the diagrams—and there are lots of them—as they make many opaque implementation topics a lot easier to understand, especially when coupled with Pat’s gentle narrative. This book is a delight for language implementation geeks and Rubyists with a penchant for digging into the guts of their tools.”
—Peter Cooper, Editor of Ruby Inside and Ruby Weekly

“Man, this book was missing in the Ruby landscape—awesome content.”
—Xavier Noria, winner of the Ruby Hero Award, Ruby on Rails Core Team Member

“Pat Shaughnessy did a tremendous job writing the book about Ruby internals. Definitely a must read—you won’t find information like this anywhere else.”
—Santiago Pastorino, WyeWorks Co-Founder, Ruby on Rails Core Team Member

“By far the best Ruby book I’ve ever read.”
—Tomasz Węgrzanowski, Ruby hacker 

“The seemingly “magic” things that Ruby does all have a clear and straightforward, step-by-step, explanation.”
—Dustin Schultz, Software Engineer

“I really enjoyed the book and now have a far better understanding of both Ruby and CS. The writing made very complex topics (at least for me) very accessible, and I found the book hard to put down. Diagrams were awesome and are already popping in my head as I code. This is by far one of my top 3 favourite Ruby books.”
—Vlad Ivanovic, Digital Strategist at Holly Sydney

“While I’m not usually digging into Ruby Internals, this book was an absolutely awesome read.”
—David Deryl Downey, Found of Cyberspace Technologies Group
