The Pragmatic Programmer is one of those rare tech books you’ll read, re-read, and read again over the years. Whether you’re new to the field or an experienced practitioner, you’ll come away with fresh insights each and every time.

Dave Thomas and Andy Hunt wrote the first edition of this influential book in 1999 to help their clients create better software and rediscover the joy of coding. These lessons have helped a generation of programmers examine the very essence of software development, independent of any particular language, framework, or methodology, and the Pragmatic philosophy has spawned hundreds of books, screencasts, and audio books, as well as thousands of careers and success stories.

Now, twenty years later, this new edition re-examines what it means to be a modern programmer. Topics range from personal responsibility and career development to architectural techniques for keeping your code flexible and easy to adapt and reuse. Read this book, and you’ll learn how to:
  • Fight software rot
  • Learn continuously
  • Avoid the trap of duplicating knowledge
  • Write flexible, dynamic, and adaptable code
  • Harness the power of basic tools
  • Avoid programming by coincidence
  • Learn real requirements
  • Solve the underlying problems of concurrent code
  • Guard against security vulnerabilities
  • Build teams of Pragmatic Programmers
  • Take responsibility for your work and career
  • Test ruthlessly and effectively, including property-based testing
  • Implement the Pragmatic Starter Kit
  • Delight your users
Written as a series of self-contained sections and filled with classic and fresh anecdotes, thoughtful examples, and interesting analogies, The Pragmatic Programmer illustrates the best approaches and major pitfalls of many different aspects of software development. Whether you’re a new coder, an experienced programmer, or a manager responsible for software projects, use these lessons daily, and you’ll quickly see improvements in personal productivity, accuracy, and job satisfaction. You’ll learn skills and develop habits and attitudes that form the foundation for long-term success in your career.

You’ll become a Pragmatic Programmer.

Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.

“Kaizen” is a Japanese term that captures the concept of continuously making many small improvements.

The Reviews

This is what I call a “peas and carrots” book. It’s not a bad book and it’s hard to argue with anything the authors advocate, but to me it’s a lot like a self-help book in that people will feel good while reading it (and thus rate it highly) but in the end a lot of people will not actually follow the material and unless you’re a newbie a whole lot of it will be pretty obvious. I know this because I’ve been working in the software industry for 20 years and this is hailed as a classic, yet people continue to make the same mistakes. This isn’t the book’s fault really, but I also feel like the book covers a lot without saying much at all. It’s similar to a self-help book for people who are feeling down, they might feel good reading it but does it really genuinely help you in the end? I suppose that depends on the person.Don’t repeat yourself (DRY), always be learning, be mindful of how you name your variables, avoid code rot, don’t over-engineer, don’t make excuses when you mess up, write unit tests, use version control, avoid global variables, use properties or getter/setter methods, work well with others, refactor your code when needed, break down complex problems into smaller more digestible chunks, double-check emails before sending them, etc etc. These are the concepts this book talks about.This is more a “why” book and less a “how” book. It does talk about the hows from a birds-eye perspective but it never really digs deep into any particular topic, rather it uses (well written) flowery language to say a lot without saying a whole lot. I really feel like this type of book, for the most part, could be distilled down into a couple pages of bullet points and not lose too much effect. It is well written though, so it’s kinda fun to read in a feel-good sense.There are good nuggets of information in this book and some topics are covered a bit more in depth than others, but in the end I think you will feel good while reading it because it is easy to read and agree with it, especially for a book focused on programming, but I don’t think you’ll come out of it leveling up your skills, especially if you’re experienced. Despite people saying that this is a book for all levels, I feel like you’ll get more out of it if you’re a new developer. For experienced developers, as I mentioned, it will serve as a gentle reminder of what you should do, even if you don’t follow the advice given when you’re finished with the book.One thing worth mentioning is that I purchased the Kindle version and it's done proper. There are no issues with blurry text or bad formatting like I see with many other technical books.

Read this as a book club with some coworkers - all software engineers. This book is wordy, rather pretentious, and creates unnecessary acronyms that only serve to complicate fairly simple/common-sense concepts. Overall, it hasn't much helped us grow as developers.

A friend convinced me to get this book when it came out in 99. Before that I was an opinionated zealot about specific programming languages, technologies and frameworks. I've applied the advice given in this book every day since then and it's become a guiding principle of how I hire software engineers to my team.

This was a gift for a top notch experienced programmer for Christmas. He mentioned wanting this book. He said it is a great book and he was very happy that I bought it for him. I believe he was telling the truth and not just being polite.

I think this book should be a textbook In programming schools. I loved this book! So many great takeaways. I read this religiously like a textbook while making notes.

It had been on my "need to read" list for a long time, I just hadn't gotten to it. Seeing the 20th Anniversary version come out made me realize it was way past time. I am reading in small chunks to give me time to thoroughly digest each nugget. It should be required reading for all programmers.

This book will teach not about codes, sometimes you can read but the main idea is to be a better programmer and think better, crack the problems, think about algorithm by yourself. There is not much to say, see the first edition was written 20 years ago and when you start reading you see the quality of the book.Its divided in some topics inside some subjects. You can read by look or follow cover to the end.This book does not have a specific language or a 'recipe' to follow, actually it will open your mind to think better.Totally recommend!!

In my opinion, this book should be a required read for anyone of any level and in any position in the software development/engineering field. This book teaches so many solid and timeless principles that could possibly take years or decades for the average person to learn, if ever.Before reading this book, I didn't know where I stood as a developer after 15 years of doing it. I'm self-taught, and also learned from my surroundings, assuming that people in higher positions than me must know better - now I never assume anything about anyone or anything. I never got much (useful) feedback but I wanted to be as good as I could be in my field. Reading this book and applying what I learned from it eventually lead to a great confidence in my way of problem solving and coding, and this confidence naturally caused me to be happier, and that's when I realized that when I'm confident and happy I produce my best work that I'm proud of. Not only do I feel like I have leveled up as a software engineer, but I also feel like I leveled up as a person. I also feel validated for a few things I was already doing, and learned that soft skills (communication, accountability, etc) are just as important as hard skills (coding).I've already convinced at least 3 developers to buy their own copy, and I'm about to suggest it to a few more, so I think I need to look up some kind of referral/commission program.This book is worth every penny and has me going back to it for reference all the time.

There is a slew of useful tidbits in there that will appeal to programmers of any language. Quite impressive.

I read the original Pragmatic Programmer years ago, and now read the 20th anniversary edition with some of my colleagues. It was an important book to me early in my career, and still has lots of useful reminders and updates with the new edition.I wish the whole book was available as pages on the public web. It's "written as a series of self-contained sections" in a way that would work really well with hyperlinks.

I have been a long time fan of The Pragmatic Programmer since I read it in the original form. The first edition is great but maybe a little dated here and there. This book takes that book and just made a masterpiece out of it. If there was only one book I could recommend for other programmers to read it would have to be this one. You and your coworkers will thank you in the future.

This book is so much more than a programming book. It is the mentor we all need, to become true professionals. It is easy to read and digest, yet so wise. I refer back to it often & am becoming a better person because of this book. I know that is a crazy and bold statement, yet I stand by it.

I seen this book popping up as a "must read" for a programmer so I decided to get it.I am still a student and have no professional experience. This book is a great read for someone who is still learning, or looking for answers to "why" ? It is a good quick reference guide. It provides a nice break from all of the really technical reading that is needed for all the classes. It has key concepts all in one place. Authors talk not only about the code but personal responsibility, career development and architectural techniques.

What an excellent book. For my this is most important book for programmers.It contains a lot of tips which will help you to become a better programmer, it discussed many topics, such as working on a team, use of IDEs, DevOps, security, patterns, among others.It has a lot of stories and recommendations which are very helpful for anyone. No matter if she/he is a novice programmer or even a senior developer. I even have more than 15 years of experience and this book was very helpful for me.

The person whose gift it was is in love with it the size colors etc

Excelente libro, adicional llegó en perfectas condiciones

It came with some scratches and damage at the edges of the cover, also there's one page that seems it wasn't cut off well

I bought this book because a lot of people recommends me and i started to read this a few days ago. The content of this book guides and give a los of tips to become more pragmatic and efficient in our work.100% recommended

I would recommend this book to new devs which have been given monoliths. This book teaches not only how to be a better dev, but how to be a better project participant. It's one of those books you can reread because you probably missed something the first time. It's packed so full of useful information, that one has to read it pragmatically. ;)

Great for programmers of any skill level and a must read for all interested in growing as any kind of programming in professional.

This book should be required for every undergraduate in CS or EE that aspires to make programming a part of their career. The text is less about software engineering, design patterns, or algorithms and more about how to make your programming environment and skill set take you from learner to professional.It is a guide to becoming an excellent programmer, plain and simple. As a computer engineering student, I wish this text would’ve been required in one of my introductory programming course. From tips like keeping your knowledge in plain text to customizing your shell, this book is filled with seemingly small suggestions that over time shape the way you work and think.

If you feel unmotivated and lost, reading this book will guide you!You can skip the order of the contents and go directly where it better suits your situation.


Came brand new with the sealing intact! Will be using this for my Environmental Science class this upcoming fall semester.

Glad it shipped to my country via Amazon Global shipping. The tips are good and the practices advocated are things that are relevant to my career and will remain relevant from years to come. I can see myself reading the book again years in the future.

Book is interesting and you can learn more from it. But book quality is not good. As soon as i received it i saw it was damaged.

Actually cool. Helped me be a better software engineer. Helps me see short coming in my own process. But i

Writing a hello world is the starting point of a software developer career, but it’s quite far from a real SE who can deliver something useful and solid. Reading this book gives you clear direction where you head to to pursue a successful career in software development.

I have to this day bought this book 6 times in physical copies, and 1 time electronically, I keep gifting it to other craftsman who can gain from this book, and they keep gifting it forward.So like the title said, read it, you won't regret it.

I only used the hat a couple of times this winter, and the last time was to a Korean BBQ, so everything had to be washed. There was no washing instructions tag, and I didn't check the Amazon page for instructions, so figured a light wash and hang-dry should be just fine. This hat was replacing a much older one, similar style, that I lost in Arizona. Well... it came out full of pile on both sides. So I grabbed one of those electric pile shavers, and much of it was coming off, but it snagged the cap a few times creating multiple holes and ripping the bottom pretty badly. Super bummed, so I wanted to share this that you DO NOT MACHINE WASH THIS HAT! These photos show one of the holes and the ripped bottom, and even though I already shaved it quite a bit, you can see that it's lost the smoothness it had. I hope this helps.

This hat was just as pictured. Sadly, I had to return it, but only because it was too small for my head (I purchased the orange & it came exactly as it appears in the pics). I have a large head that measures in at 7 3/4 (in a female).I think it’ll look great on anyone & is super trendy looking. Since it didn’t have “give” it’s solidly made & the material isn’t harsh or itchy.I was able to return this with ease & was refunded within 2-3 hours. Wishing it had worked out, as it was super cute. Thanks for reading this review.

I work at home and live in New England where things are really cold. I like to stay cozy so I often wear a light weight hat in the house. I decided to spoil myself for Christmas so I purchased a lovely cashmere beanie to up my game.It is just so lovely. Super soft, generous slouch but not messy. The knit is beautiful with a delicate dart knit. My original order was for the periwinkle one and the color is scrumptious. I immediately ordered two more. I slept in the pink one last night, and gently pulled the edge over my eyes as the sun came up and it was a dreamy nest I never wanted to leave. The price is right. These are great.

This would have recieved 5 stars if the color was actually as advertised. I ordered this because the "pink" as shown would go with what I have. This is a very very tan pink. In fact, I am hard pressed to say it is pink at all.Having said that, the material is very soft! The fit is very comfortable! And the quality is great!.

This is a lovely hat. It’s soft and comfortable. It fits well. The color matches the illustration in the ad. Because the edge is knit smaller than the rest of the hat, it fits securely without being too tight. It feels snug and probably won’t slip off. I think my head is average size and it fit me well. I would definitely purchase this hat again!!

This hat performed much better than I expected. The color was exactly as pictured. I was able to fit it over my very thick, long braids and still look put together (and cute 😍). Plus, it was warm. I tested it out in those below zero Temps we had before the holiday. Will definitely repurchase.

Great hat, great buy. Already ordered more in different colors. I have ordered several beanies over the past few years and sadly most live in a drawer unused. Time to donate those. This beanie has a great shape on my head and has enough room to put my very long (but thin!) hair inside if I want to. If you have thick hair and/or long dreads, this won’t fit all your hair inside. I am super happy with this hat and quick shipping. Side note: I am allergic to wool and even though this is a very soft yarn, I do wear this over a thin cotton beanie (also purchased on Amazon).

I love this hat! It is super soft and very flattering. Not bulky at all. The slouch is so nice. Hangs perfect. I ordered the black one. I am definitely going to buy more

Book is interesting and you can learn more from it. But book quality is not good. As soon as i received it i saw it was damaged.

I really enjoyed reading The Pragmatic Programmer. My team read it for an at work book club. I think the book has solid advice and fundamental principles for good software engineering. It has a good mix of content relevant to the different parts of being a good software engineer around both code and processes.
