Book cover of Beyond the Basic Stuff with Python: Best Practices for Writing Clean Code

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 Domain-Specific Languages

Alexander Granin Author Of Functional Design and Architecture

From my list on domain modeling.

Why am I passionate about this?

If someone had told me during my early professional years that I would become a strong advocate for functional programming and the author of a fundamental book on functional software engineering, I would have found it hard to believe. Was functional programming truly worth dedicating my life to? However, once I experienced the sheer beauty of functional programming, there was no turning back. I delved deep into Haskell and functional C++, and began writing articles, giving talks, and developing various technologies. I realized that I possessed a truly unique perspective on approaching software engineering in functional languages, and that there was a significant knowledge gap that needed to be filled for the benefit of all.

Alexander's book list on domain modeling

Alexander Granin Why did Alexander love this book?

It was a wonderful time when I first embarked on my programming journey.

I felt an immense sense of power over computers and had countless ideas on how programming could improve my life and the lives of others. Everything seemed within reach, and I approached the world of programming with great enthusiasm in the early 2000s.

However, reality hit me like a cold shower when I started delving into actual software development. I quickly realized that it was far more challenging than just writing code.

Each programming language and technology had its hidden complexities and treacherous pitfalls. Every domain was rife with intricate nuances that had to be understood before attempting to develop software within it. I soon discovered that there was no such thing as a "perfect solution" that could be universally applied.

As I ventured into working with real-world domains, I confronted the daunting task of addressing the…

1 author picked Domain-Specific Languages as one of their favorite books, and they share why you should read it.

What is this book about?

When carefully selected and used, Domain-Specific Languages (DSLs) may simplify complex code, promote effective communication with customers, improve productivity, and unclog development bottlenecks. In Domain-Specific Languages, noted software development expert Martin Fowler first provides the information software professionals need to decide if and when to utilize DSLs. Then, where DSLs prove suitable, Fowler presents effective techniques for building them, and guides software engineers in choosing the right approaches for their applications.

This book's techniques may be utilized with most modern object-oriented languages; the author provides numerous examples in Java and C#, as well as selected examples in Ruby. Wherever possible,…


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.

1 author picked Head First Design Patterns as one of their favorite books, and they share why you should read it.

What is this book about?

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,…


Book cover of Growing Object-Oriented Software, Guided by Tests

Jan Van Ryswyck Author Of Writing Maintainable Unit Tests: Mastering the Art of Loosely Coupled Unit Tests

From my list on starting your software developer journey.

Why am I passionate about this?

I’m a professional software developer for more than 22 years now. I’ve used many programming languages, platforms, frameworks, etc. throughout my career. However, the only constant for me personally was the practice of Test-Driven Development. I’ve never stopped learning about the principles and practices behind it, and it paid huge dividends throughout my career. I’m very humbled and grateful to be able to learn from all those amazing people over the years, that I decided to write a book on the topic. Giving back some of the knowledge that I gathered about TDD throughout 18+ years. 

Jan's book list on starting your software developer journey

Jan Van Ryswyck Why did Jan love this book?

I must admit that the first time I read this book, it completely didn’t resonate with me. Sure, I picked up a couple of very important concepts here and there. One of those concepts is the “Test Data Builder”. However, some of the techniques I completely rejected. It took me a couple of years to start opening up to the practices described in this book. After a second read, I came to the conclusion that this excellent work deserved more credit. That’s why I added it to this list. This book shaped my entire thinking around Outside-In TDD, which is a very important approach to guiding well-designed software systems.

Book cover of Algorithms

Daniel Zingaro Author Of Algorithmic Thinking: A Problem-Based Introduction

From my list on for actually learning how to design algorithms.

Why am I passionate about this?

I love pulling back the curtain on how computers work. I want to go from thinking "that's magic" to "that's unbelievably clever but now I understand how it works." Each time I am able to do this feels like a hard-won but therefore meaningful step toward understanding. I want others to experience this empowering shift. 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's book list on for actually learning how to design algorithms

Daniel Zingaro Why did Daniel love this book?

Many of my favourite algorithms books give short shrift to designing APIs for the algorithms and data structures that they present. The Sedgewick and Wayne book, by contrast, goes all in on an object-oriented API design. This is my book choice for Java programmers and those interested in larger program design considerations. Clear your calendar: each chapter here is massive, but I think the time investment is worth it. I especially like the chapter that shows how to tune classic algorithms for realizing speedups when working with strings.

Alexander's book list on domain modeling

Alexander Granin Why did Alexander love this book?

I'm a devoted advocate of functional programming and a passionate Haskell enthusiast.

Ironically, there was a time in my life when I was a student and held the belief that functional programming was merely an impractical academic pursuit.

However, I soon had a revelation that the techniques I employed in C++ to mitigate the inherent unsafety of the language actually aligned with the core principles of functional programming: immutability, purity, and composability.

This realization left a profound impression on me, prompting me to delve into learning Haskell. It proved to be a pivotal moment that significantly shaped my entire career trajectory.

As I delved deeper into functional programming, I discovered a significant void in terms of software engineering practices that were prevalent in the realm of object-oriented programming.

Drawing from my experiences in C++ and C#, I noticed numerous gaps in our understanding of how to build robust applications using…

1 author picked Function and Reactive Domain Modeling as one of their favorite books, and they share why you should read it.

What is this book about?

Functional and Reactive Domain Modeling teaches readers how to think of the domain model in terms of pure functions and how to compose them to build larger abstractions. It begins with the basics of functional

programming and gradually progresses to the advanced concepts and patterns needed to implement complex domain models. The book demonstrates how advanced FP patterns like algebraic data types,

typeclass based design, and isolation of side-effects can make models compose for readability and verifiability.



On the subject of reactive modeling, the book focuses on higher order

concurrency patterns like actors and futures. It uses the Akka framework…

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

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.

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…


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 Dream Again

Danyelle Scroggins Author Of Blame It On My Boots

From my list on for spiritual growth, healing, and hope.

Why am I passionate about this?

In every book that I have recommended, you’ll find the dynamics of family and love. I’ve been a pastor for over fifteen years and now work as an author of both Christian fiction and non-fiction books. I'm a Chaplain for a Trauma One leveled hospital, and I counsel people of all ages. My master's degree in Religious Education is also a much-used tool as I’ve used education to deepen my quest to obtain knowledge. My love of books about family and love began when I lived in Yokosuka, Japan. I was far away from my family, beginning a new chapter with my own family, but right on the verge of learning how friends can truly turn into family.
