Best technical writing I've read in years. Eloquently stated pragmatic advice on how to structure object-oriented code to withstand constant change without driving you to drink. Worth reading for anyone writing OO code, Rubyist or not. ( )
This book gets an inordinate amount of praise, for reasons I won't speculate here. It's an OK book on a *purely* technical basis. That is, if you can ignore the distractingly bad writing.
I mean, it's *really* badly written. There are so many run-on sentences that it's a huge distraction. And it gets worse in the later chapters, which are very slapdash. The few semi-colons that appear are almost inevitably used where a colon should be.
Some paragraphs contain almost verbatim information that appeared on the facing page.
And what is supposed (I think) to be "breezy" ends up being meandering and forced. Really getting "breezy" right in a technical book is almost impossible. Most writers shouldn't attempt it.
Nevertheless, there are some important and useful ideas here. But this book was in DIRE need of a real editor. Whomever Addison-Wesley paid didn't do their job.
Great book on software design - and it's concise. Review here: http://7fff.com/2012/11/25/sandi-metz-practical-object-oriented-design-in-ruby-b...

The Complete Guide to Writing More Maintainable, Manageable, Pleasing, and Powerful Ruby Applications Ruby's widely admired ease of use has a downside: Too many Ruby and Rails applications have been created without concern for their long-term maintenance or evolution. The Web is awash in Ruby code that is now virtually impossible to change or extend. This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples. Sandi Metz has distilled a lifetime of conversations and presentations about object-oriented design into a set of Ruby-focused practices for crafting manageable, extensible, and pleasing code. She shows you how to build new applications that can survive success and repair existing applications that have become impossible to change. Each technique is illustrated with extended examples, all downloadable from the companion Web site, poodr.info . The first title to focus squarely on object-oriented Ruby application design, Practical Object-Oriented Design in Ruby will guide you to superior outcomes, whatever your previous Ruby experience. Novice Ruby programmers will find specific rules to live by; intermediate Ruby programmers will find valuable principles they can flexibly interpret and apply; and advanced Ruby programmers will find a common language they can use to lead development and guide their colleagues. This guide will help you Understand how object-oriented programming can help you craft Ruby code that is easier to maintain and upgrade Decide what belongs in a single Ruby class Avoid entangling objects that should be kept separate Define flexible interfaces among objects Reduce programming overhead costs with duck typing Successfully apply inheritance Build objects via composition Design cost-effective tests Solve common problems associated with poorly designed Ruby code
