Practical Object-Oriented Design in Ruby: An Agile Primer (Addison-Wesley Professional Ruby Series) (English Edition) eBook: Sandi Metz: Amazon.fr: Amazon Media EUS.à r.l. While the industry moves towards Functional Programming Paradigms and away from Object Oriented Thinking, Sandi Metz s book, Practical Object Oriented Design in Ruby, published in 2012, still stands the test of time with OOP best practices It is truly a practitioner s guide to Navigating Changing Requirements and being truly Agile.The book addresses OOP Anti patterns and the Reader is taken through iterative steps in evolving the Example Applications throughout the chapters In some ways, it can be likened to thinking in of a Data Modeling Manner, though adapted for OOP instead of Relational Databases.If you work in Software, you should read or re read this book The author also has a recent book available through her web site, which is of similar quality though has of a Programming or Puzzle like Feel. I hate bronchitis Reading Practical Object Oriented Design in Ruby was a blast Reading it while ill was frustrating Lots of thought provoking ideas written in an easy to read style I kept falling asleep due to sickness and my brain kept yelling This is cool Stay awake Still, Sandi achieved her goal even through my fog of exhaustion I now see objects very differently and will happily refactor my code to make it better.The only real ding to the book is Chapter 8 s references to Enumerable and Forwardable Everything else in the book was either easy to read or well explained These two characters seem to have slipped in without fanfare or explanation I don t understand them and thus probably missed some of the book s goodness Perhaps I ll get it later I still rate this book a 5 star buy Despite being almost 7 years old at the time of this review, it s still a very relevant book If you re an experienced Ruby developer, many of the concepts described in this book may already be familiar But I think there s good value in having these ideas described clearly and with good examples The book gives details on when to use and when not to use certain techniques You may also find this book fill in some gaps in your knowledge as a Ruby developer.Tip Watching Sandi Metz presentations at conferences which is readily available on YouTube is a good complementary material to this book.On the other hand, for an experienced Ruby developer, this book can also be a little boring if you re already familiar with many of the ideas You still gain better understanding of the concepts but it can feel a little slow.I m also not a fan of the Kindle format in general and this book is not an exception I m pretty sure the physical book has a much better formatting, but I try to avoid having too many physical books at home If you re undecided between getting the physical or digital copy and you don t have a strong preference, get the physical book. I have programmed in Ruby for a number of years now and still found this book of value I would not recommend it for absolute beginners because it assumes knowledge of the language, though you will learn general principles I would recommend it for anyone wanting to get a better grasp of writing good object oriented code, especially in Ruby I found it helpful to think of Messages sent instead of just the class hierarchy. This is my favorite tech read so far this year It takes a straight forward approach to writing code that you won t hate yourself for a day or month or year later.The term design in the title is not referring to making wild speculative guesses about the future and planning for any number of contingencies, it is about arranging the code so that it is understandable, and to minimize cost and pain.There is a focus on designing the communication between objects as much as focusing on the structure of the objects themselves, which I found to be extremely interesting This discussion helped clarify a lot of thoughts and ideas about abstractions and where responsibilities belong, as well as the directions of dependencies things that had been rattling around in my brain for a while but that I had trouble applying in the real world Reading this let me put all these pieces together and then some into a coherent whole Or at least a coherent seed of a whole.The code examples are simple, but the author manages to wrangle some serious dramatic tension out of every line of code, and they illustrate the concepts covered well enough that I was able to make the leap to applying the concepts in much complex code bases.The chapter on testing was sublime It took an immensely practical approach to which methods to test and which tests to write in order to avoid duplication and brittleness in both tests and designs.I also appreciated that none of the discussions were about any sort of moral superiority The discussions were about getting things done The argument for arranging code nicely wasn t about aesthetics or professional duty, but rather about lowering cost and allowing you to make changes without causing expensive outages and making people frustrated.Soap boxes Sure High horses Nowhere in sight.Note I read a pre release version of the book I did not know the author at the time, but sent her quite a lot of feedback, which led to several conversations to clarify When I waxed enthusiastic about the contents, she asked if she could forward this to the publisher, and a quote ended up in the paper copy.
