"Everybody complains about the weather but nobody does anything about it." Likewise, everyone has an opinion about what good code looks like, but those opinions don't help you create it. This book fills that gap. It explains the process of writing good code, and teaches you to achieve beautifully programmed ends by way of extremely practical means.

This is not just a book on OOP, it’s basically a full blown OOP course you can follow along at your own pace wherever you are. The domain is so simple that anybody can grasp it in a very short time, no need to know anything about bikes - looking at you, POODR… :D

The whole thing is quite ambitious, as Sandi and Katrina say in the preface “it turns out that everything you need to know about Object-Oriented Design (OOD) can be learned from the 99 Bottles of Beer song. Well, perhaps not everything,

Really great book, I devoured it in 3 days. The style is very similar to Kent Beck's "Test Driven Development by Example": it describes concepts of object oriented, refactoring and good design working iteratively on a very simple exercise over several chapters (the 99 bottles of beers). I would have never thought that such a simple code could be source of so many challenges and inspiration ("horizontal refactoring" and "Flocking rules" are very interesting practices as well as kind of mindsets). ...more

This is an astonishing book about OOP and good coding in general. It's great both for people that want to bring back memories but also for newcomers that just learnt coding (although they should certainly read the references that the book provides as well).

Much like Kent Beck's TDD book, 99 Bottles is a chance to pair program with Sandi and Katrina. During the programming, you'll discover at least four fundamental techniques for refactoring, each of which justifies the purchase, along with concrete examples of how to apply the concepts to real code. I recommend this book to all object-oriented programmers, whether you are using Ruby (as per the specific examples in the book) or C#, Java, TypeScript, PHP, et al.

Read it again after the last two chapters had been published. Fantastic book! as mentioned in previous comments this is a full blown OOP course! you may see familiar techniques in case you've been doing OOP for a while however, it totally worth reading. It's perfect to be read after the Practical Object-Oriented Design in Ruby (also from Sandy).

If there’s any fault with little book on object-oriented programming, it’s that it sometimes feels slow—especially if you already know where’s it’s headed. But that’s exactly what makes it great. It goes through the logic of every step in the thought process—even parts that are “easier done than said.” There’s nothing left to mysterious hand-waving here.

I’m going to go on record and predict that this will be a classic. It brings clarity to many of the misunderstandings that continue to surround

Very clear writing and step-by-step walkthrough of refactoring, with explanations for why to make certain choices. If you get a chance to take her in-person workshop, definitely do that, but this is a good companion resource if you don't have that opportunity or need a refresher.

The book describes a program that prints the 99 bottles song, and more importantly the detailed steps of refactoring the program. The task seems to be pretty simple, but in fact the average, basic code for the solution is far from ideal, and the book explains how to improve it. From this point of view, it's a perfect fit. I'm impressed by the detailed explanations of the refactoring process.
It's also interesting to compare it with this article: https://fsharpforfunandprofit.com/pos... , which de

Sandi Metz's prior book Practical Object Oriented Design in Ruby (POODR) sets the bar very high, so I had higher expectations for this one, but it is still absolutely worth reading. It focuses on different strategies and tradeoffs when implementing a ruby program that spits out 99 Bottles of Beer song. It covers topics like naming, extendability, developer speed, changing requirements, abstraction etc..

This book has written for a pretty wide audience (TBH I think that this audience is too wide). I'm not sure that it's worth reading for experienced software engineers, there are no things that will blow your mind, but I'll definitely recommend this book for junior/middle-level devs.
Please, guys, don't ignore practice! Try to write your own solution of 99 bottles and then see, how it differs from Sandi's solution. Even better if you'll be repeating refactoring step by step, as shown in the book.

This book is definitely among the top 3 best books about programming of all time. Sendi Metz and Katrina Owen lead you to the solution of a well know problem. Not too complex and not too shallow, just at the right level that allow them to exemplify how to make decisions about code design at every step of the way, all guided by tests. Can't recommend this enough, I will most certainly read multiple times.

TDD and refactoring seem so obvious and straightforward when Sandi Metz walks you through them. This book almost convinces me to mend my evil habits and TDD everything. Almost, but not quite. Very much worth reading, but in the end I consider it another in a suite of useful techniques for developing good code, not the only way to do it.

Fun and enlightening read. If you're a developer, regardless of your experience, this is a great book to have in your bookshelf. It certainly made me want to review my code and see where can I apply all these new knowledge.

A very detailed book on how to use different practical techniques in TDD and refactoring to approach a seemingly simple problem but containing different level of abstraction. It would be great if the book can give an example of "Replace conditional with state/strategy" as in appendix.

If you're into Refactoring, this book is for you: really amenable and easy to follow, well written, focused and practice driven. The only bad thing I can say about it is that the same code snippets are repeated to much times, instead of just referencing it.

Great practical guide on refactoring by coding the 99 bottles problem. The explanations given for design choices are detailed enough for a relatively novice developer to understand. Reader is left with a number of easy to remember strategies for methodical refactoring.

Great book – it provides a step-by-step guide for a rigid software design process. An easy-to-read and practical advice on refactoring, TDD and object design.

Enjoyable writing style and very informative, for experienced and novice developers alike. It's worth having a go at the sample problem, it's deceptively not-as-simple as it seems!

A very gentle and exemplary intro to OOP, even though the code is in Ruby I would recommend this book to any developer who wants to learn / refresh their knowledge of core OOP principlies.

I’m fascinated by the way this book challenged many misconceptions of mine on so many levels. Sandi Metz not only writes truly elegant code, but is a fantastic guide through her mental process.

I will probably do more vertical refactoring even if horizontal refactoring allows you to write better tests.

Still in beta but already a great book on object oriented programming. A simple song of 99 bottles is all it takes for Sandi Metz and Katrina Owen to explain the design decisions one can take to turn a piece of code into an easy to understand solution.

Easily one of the best programming books I've ever read. Great overview of OOP and walk-throughs of best practices: from how to approach testing, refactoring and even naming things.
