This is a pretty awful book. The author has at best a tenuous grasp on object oriented programming. Pick up The Ruby Way instead.

Must have if you programming Ruby.

Great book to learn ruby.

You definitely shouldn't read it like a normal book... It's more like a "reference book"

A very handy guide. Will keep around for checking up on things.

Great reference work that also manages to be a good introduction to the language itself. Not the bets place for Ruby on Rails, but an essential addition to your Ruby library.

The key reference for understanding the Ruby programming language. If you want to be up-to-speed on Ruby you've got to have this book. I also have the PDF version which is great to have if you're not by your bookshelf.

Old but gold, back to the time where lamdba is frequently called Proc, reflection for the term metaprogramming, not surprising surprisingly Profiler. For me the diamonds are `Object-Oriented Design Libraries` and `Sharing Data Between Ruby and C` makes me think about native approachs POROs more than the go-get a library.

It provides a ground surface for new developer who wanted to step into Ruby, a beautiful interpreter language supporting OOP-first in its design. The patch for this book should be Ancestry chain to know deeper about the inheritance and newer Enum map-reduce for FP paradigm.

There are many ways to achieve a purpose in Ruby, the freedom of choice, to sail a ship into the ocean, to know the vast ocean, to gain the knowledge. Writing Ruby is a joy!

This was a hard read to me and it took so much of will to finish it so I am not too sure if I would like to ever re-read that book or even answer affirmative to the question if I would read it at all if I knew how hard it was. Don't get me wrong, there is useful information, it is a known classic and it provides an overview of the language, but the writing style is sometimes too abstract or just doesn't spark interest (for me).

Programming Ruby: The Pragmatic Programmers' Guide, Second Edition by Dave Thomas (2004)

My current class @ UW Extension College

The "pick axe" book; more than a reference it's fun to read
