How do you design user-friendly APIs in Rust? The answer is easy: you use them! Let’s build a simple Rust CLI tool using what I call the “magic function” approach.
What are the best Go books in 2025?
What are the best Go books this year? Read my (relatively) unbiased recommendations for the Go books you should absolutely buy and read right now, whether you’re a beginner or expert Gopher.
Rust vs Go in 2025
Which is a better choice, Rust or Go? Which language should you choose for your next project, and why? How do the two compare in areas like performance, simplicity, safety, features, scale, and concurrency?
Why you can't meditate
You can't clear your mind, or achieve bliss by sitting on a special cushion. But you can start to gently train your brain to stop craving distraction and overstimulation. In this excerpt from Monk Mode, we'll see how.
Undertesting and overtesting
Tests are great, provided they actually test something. But are your tests too optimistic (assuming the code already works), or too persnickety (testing the irrelevant)?
Rust and Go vs everything else
Alex Pliutau and I discuss what Go programmers should know about Rust, and why the two languages make perfect partners.
Constraints in Go
Freedom is nothing without constraints, and Go’s generics gives us a powerful way to build polymorphic types and functions constrained by type sets. Let’s geek out.
Generic types in Go
What kind of idiot would carry a package for someone when they've absolutely no idea what's inside it? Well, generic types in Go are exactly like that, only in a good way.
Testing legacy code
How do you rescue a legacy codebase that has no tests? Let's look at some techniques for clawing your way back to maintainability, one test at a time.
Programming is fun
I was a guest on the Cup o’ Go podcast recently, talking with Shay Nehmad and Jonathan Hall about writing and teaching Go. Here’s a transcript of our chat.
Cryptography in Go: AES encryption
AES is an amazing, state-of-the-art encryption system, and it’s built right in to Go as part of the standard library. It’s also incredibly easy to use. Let’s see how!
Functional programming in Go
Thanks to generics, there are some interesting new ways to program in Go. This article explains how we can use functional programming techniques like Map, Filter, and Reduce, and what kind of problems they might help us to solve.
Iterators in Go
Iterators in Go are a neat way to write “lazy loops”, where we never generate more results than we actually use. Let’s see what that would look like in Go programs, and what new facilities it gives us in the standard library.
Bitfield Institute of Technology
The Bitfield Institute of Technology (BIT) is a software engineering school that offers remote training and certifications in Go development to students worldwide.
Will write for food
In the final sizzling chapter of my career exposé, we’ll learn how I went from self-unemployment to founding the world’s tiniest publishing empire.
Seven Rust books that don't suck
There are many Rust books, but these are my favourites—and I think you’ll like them too. Here are my reviews of what I think are the truly essential Rust books available today.
Shameless green
Building software is easy when we’re guided by tests, because we can start with quick-and-dirty solutions, without worrying about whether the code is elegant and readable—yet. Let’s see how to use the TDD technique called “Shameless Green”.
Rust error handling is perfect actually
The night is dark and full of errors, so how should we handle these gracefully and safely in our Rust programs? Let’s introduce two of every Rust programmer’s favourite types: Option and Result.
Cryptography in Go: AES implementation
The AES cipher is complicated in principle, but the code isn’t all that scary in practice. Let’s take a look at the implementation in the Go standard library. Even I can understand it!
If you need the money, don't take the job
Money: how to get people to give it to you, how much to ask for, and how to be worth what you're asking. Some real talk about the challenges you’ll face as a newly independent worker.
