Book cover of Effective C++: 55 Specific Ways to Improve Your Programs and Designs

Jeff Langr Author Of Modern C++ Programming with Test-Driven Development: Code Better, Sleep Better

From my list on doing it right in your programming language.

Why am I passionate about this?

I love computer programming books almost as much as I love computer programming. As a high school student in 1980 I remember typing in really frustrating source code from the book BASIC Computer Games. Was programming meant to be a black art? Was code supposed to be an impenetrable mess of buried intent? When I started getting paid to program, I was happy to see that the answer to both questions was "no." I began to seek and enjoy books that espoused the "right" way to code in a given language. Here is a handful of books that have helped me and countless others learn to produce correct, clear, and maintainable code.

Jeff's book list on doing it right in your programming language

Jeff Langr Why did Jeff love this book?

C++ is a tricky, beastly language, and there are no end of ways to program either incorrectly or inefficiently with it. Meyer's 1991 book set the bar high for similar books to come, providing great, detailed explanations about the language's pitfalls and how to avoid them. After reading Effective C++, though, you might find yourself wondering why you are coding in C++: The tips reveal so many insidious ways to shoot yourself in the foot, and worse, sometimes in a way that you won't even notice that your little toe is missing.

Effective C++ and the two follow-ons are essential reading for anyone working in C++. Nowadays you can purchase a digital edition that provides 140 total ways—adding in 50 additional tips from More Effective C++ and 40 from Effective STL.

Book cover of Smalltalk Best Practice Patterns

Philipp Fehre Author Of JavaScript Domain-Driven Design

From my list on learning from programming classics.

Why am I passionate about this?

Computers have fascinated me since my childhood, having fond memories of my dad's ZX81, but even so I played around I was never truly captured by the programming until I recognized it as a way of writing rather than raw engineering. Through my studies of media sciences I found my fascination with how language can shape perception, and through my work in developer advocacy, I found how communities are shaped as well. Now I am fascinated with how different programming languages can shape thinking, having had the opportunity to solve problems at large companies in nonmainstream languages.

Philipp Fehre Why did Philipp love this book?

Smalltalk is not as common or popular as it once was, but the influence its design had on programming is hard to overstate.

Reading this book has changed how I think about object orientation, and how I design systems, learning the patterns of Smalltalk makes it clear what object oriented design is really intended to achieve.

Jeff Langr Why did Jeff love this book?

When seeking a book on how to use a language effectively, getting one written by someone who helped design and implement the language is usually a great idea. With Effective Java, you get a book written by someone who contributed a significant amount to the language: Joshua Bloch had a lot to do with the design of the Java 5.0 features circa 2004, which is where Java moved for me from "inelegant" to "hey I can finally make things look good in this language." Bloch goes into considerable and passionate depth about each of the 90 items in the 2018 edition and will help you ensure you don't make the mistakes that can lead to defective or bad code.

Jeff Langr Why did Jeff love this book?

During my first few weeks of JavaScript coding, I encountered what seemed to be an endless number of head-scratching moments: "I'm slowly reading the few lines of code I just wrote, it seems fine, so why isn't it doing what it looks like it should be doing?" Even more insidious at times than C++, JavaScript contains a number of fairly clever constructs, including things like hoisting, duck typing, and a loosey-goosey argument passing mechanism. This concise tome of fewer than 175 pages helped get me past those first few months, and as an author-stated goal, it helped me "learn to think in JavaScript."

Why should I read it?

1 author picked JavaScript as one of their favorite books, and they share why you should read it.

What is this book about?

Most programming languages contain good and bad parts, but JavaScript has more than its share of the bad, having been developed and released in a hurry before it could be refined. This authoritative book scrapes away these bad features to reveal a subset of JavaScript that's more reliable, readable, and maintainable than the language as a whole-a subset you can use to create truly extensible and efficient code. Considered the JavaScript expert by many people in the development community, author Douglas Crockford identifies the abundance of good ideas that make JavaScript an outstanding object-oriented programming language-ideas such as functions, loose…


Book cover of Head First Design Patterns: A Brain-Friendly Guide

Paolo Perrotta Author Of Programming Machine Learning: From Coding to Deep Learning

From my list on classic software that are still worth reading.

Why am I passionate about this?

You know what ages like milk? Programming books. I always cringe when someone glances at my programming bookshelf. Some of those books are so dated, they make me appear out of touch by association. Sometimes, I feel compelled to justify myself. “Yes, that's the first edition of Thinking in Java I keep it for nostalgic reasons, you know!” Yesterday’s software book is today’s fish and chip wrapper. However, there are exceptions. A few classics stay relevant for years, or even decades. This is a shortlist of software books that might be older than you, but are still very much worth reading.

Paolo's book list on classic software that are still worth reading

Paolo Perrotta Why did Paolo love this book?

If you check out Amazon’s best selling books on object-oriented design, you might see a relic from 1995 still hanging near the top: "Design Patterns". That book transformed software design. Its four authors will forever be known to my generation as the “Gang of Four".

Some of the original patterns may feel outdated today, but others remain essential. Pity that the book itself is such a tough read. Good thing that another "gang of four”, spearheaded by the excellent Kathy Sierra, gave us this lighthearted take on the original patterns.

The Design Patterns book was a densely packed truck of ideas. By comparison, Head First Design Patterns is a whimsical bumper car. It’s quirky and accessible, which some serious programmers found off-putting: “It’s a book for teenagers!“, they griped.

Yes, it’s not for everybody. But it’s fun, unassuming, and it teaches important concepts. So it makes my list.

You're not alone. At any given moment, somewhere in the world someone struggles with the same software design problems you have. You know you don't want to reinvent the wheel (or worse, a flat tire), so you look to Design Patterns--the lessons learned by those who've faced the same problems. With Design Patterns, you get to take advantage of the best practices and experience of others, so that you can spend your time on...something else. Something more challenging. Something more complex. Something more fun. You want to learn about the patterns that matter--why to use them, when to use them,…

Paolo Perrotta Why did Paolo love this book?

Few people want to grow up like their parents. In the early 2010s, many programmers scoffed at the design principles of the ‘90s. Why should anyone care about the nuances of object-oriented design? That’s such a Java thing to bother with!

To seasoned developers, this rejection felt like a baby and bathwater situation. Then Sandy Metz came to the rescue. Her book persuaded younger developers (or at least, those in the Ruby community) that those old ideas were still valuable.

Practical Object-Oriented Design in Ruby traced a straight line from the pioneering times of Smalltalk, through the years of the software craftsmanship movement, directly to modern programming.

It’s a timeless book in the best sense of the word: it would have felt relevant back in the 90s, or when it was published, or today. Few people want to grow up like our parents–but as it turns out, we all do.

Naomi R. Ceder Author Of The Quick Python Book

From my list on to level up your Python skills.

Why am I passionate about this?

I’ve been teaching and writing Python code (and managing others while they write Python code) for over 20 years. After all that time Python is still my tool of choice, and many times Python is the key part of how I explore and think about problems. My experience as a teacher also has prompted me to dig in and look for the simplest way of understanding and explaining the elegant way that Python features fit together.

Book cover of Refactoring: Improving the Design of Existing Code

Federico Kereki Author Of Mastering JavaScript Functional Programming: Write clean, robust, and maintainable web and server code using functional JavaScript and TypeScript

From my list on the theory and practice of computer programming.

Why am I passionate about this?

I have been working with computers for decades now – having started with programmable handheld calculators and working my way up and down through mainframes, mini- and micro-computers. I always thought there is an art to writing software, and that good software can be read and admired. Maintainability, readability, and testability are some core needs for software, and after going through many programming paradigms, I feel that functional programming (FP) is the way to go – and several modern web frameworks agree. JavaScript (and now, TypeScript) are essential to web development, and I wanted to show how FP could be successfully used with those languages, and thus my book.

Federico's book list on the theory and practice of computer programming

Federico Kereki Why did Federico love this book?

This book is different from the others I recommended, because its focus is not really on creating algorithms, but rather on how to improve code with a systematic process, keeping functionality but enhancing quality.

The author shows several practical techniques that he applies to real-world problems and empower you to elevate your code's quality and adapt it seamlessly to changing needs. It's not just about writing code; it's about becoming a more effective and confident developer.

I consider this book a companion on the journey to mastering the craft of coding. With it, you’ll always be able to achieve higher-quality code, no matter the original version of the code.

What is this book about?

Refactoring is about improving the design of existing code. It is the process of changing a software system in such a way that it does not alter the external behavior of the code, yet improves its internal structure. With refactoring you can even take a bad design and rework it into a good one. This book offers a thorough discussion of the principles of refactoring, including where to spot opportunities for refactoring, and how to set up the required tests. There is also a catalog of more than 40 proven refactorings with details as to when and why to use…


Book cover of Get Programming: Learn to Code with Python

Daniel Zingaro Author Of Learn to Code by Solving Problems: A Python Programming Primer

From my list on for a rock solid python programming foundation.

Why am I passionate about this?

Some programmers learn through online articles, videos, and blog posts. Not me. I need a throughline—a consistent, expert distillation of the material to take me from where I am to where I want to be. I am not good at patching together information from disparate sources. I need a great book. I have a PhD in computer science education, and I want to know what helps people learn. More importantly, I want to know how we can use such discoveries to write more effective books. The books I appreciate most are those that demonstrate not only mastery of the subject matter but also mastery of teaching.

Daniel Zingaro Why did Daniel love this book?

Bell is an expert teacher. I like the order of topics; the breakdown of topics into units; the short, targeted lessons in each unit; the varied capstone projects to tie things together; the explicit learning goals; the structured approach to solving problems. The first bit of code that you’ll write is on page 30. Your first complete program is on page 60. What’s up with those first 59 pages, then? Motivation, comparisons to daily life, setup, and building blocks. Things that other authors tend to skip but that may be important for some learners. Bonus feature: “I try not to forget what it’s like to start learning to program from scratch, no matter how many times I teach the course.”

Of all the books I recommend, this is practically a sort of personal bible, which I very frequently consult.

This book doesn't just show you how to code; with realistic patterns and real-world examples, it's like having experienced mentors guiding your every keystroke. These patterns aren't just snippets; they're blueprints for building robust, flexible software.

I think the book is practically mandatory for all developers, novice or seasoned. It transformed how I approach problems, teaching me techniques I use daily in systems design and development.

Capturing a wealth of experience about the design of object-oriented software, four top-notch designers present a catalog of simple and succinct solutions to commonly occurring design problems. Previously undocumented, these 23 patterns allow designers to create more flexible, elegant, and ultimately reusable designs without having to rediscover the design solutions themselves.


The authors begin by describing what patterns are and how they can help you design object-oriented software. They then go on to systematically name, explain, evaluate, and catalog recurring designs in object-oriented systems. With Design Patterns as your guide, you will learn how these important patterns fit into the…
