The Value in Go’s Simplicity
After using Go for a couple years, I’ve really come to appreciate its simplicity. I started writing Go at work a couple months ago, and have found it really easy to iterate on – much more so than Python and Java.

Clear is better than clever
This article is based on my GopherCon Singapore 2019 presentation. In the presentation I referenced material from my post on declaring variables and my GolangUK 2017 presentation on SOLID design . For brevity those parts of the talk have been elided from this article. If you prefer, you can watch the recording of the…

Let's Build a Compiler
Compilers, interpreters, runtimes, and the like can sometimes feel vaguely magical. They take your code, perform complex transformations that you only partially understand, and spit out an executable binary. Clearly, the inner workings of such a beast must contain arcane secrets, not meant for the minds of mortals.

Algebraic Structures: Things I wish someone had explained about FP
Algebraic Structures are something I wish I’d understood better, sooner. I had a hazy idea of what they were, but didn’t know the correct terminology. That was a massive barrier to finding out more. This article is my attempt to stop that happening to others. We’ll look at: What are algebraic structures? How do we use…

A final proposal for Rust await syntax
This is an announcement regarding the resolution of the syntax for the await operator in Rust. This is one of the last major unresolved questions blocking the stabilization of the async/await feature, a feature which will enable many more people to write non-blocking network services in Rust. This post contains…

Go Slices Are Fat Pointers
One of the frequent challenges in C is that pointers are nothing but a memory address. A callee who is passed a pointer doesn’t truly know anything other than the type of object being pointed at, which says some things about alignment and how that pointer can be used… maybe. If it’s a pointer to void ( void * ) then…
