You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
Image differentiation in three languages
The Visitor Pattern is one of the most mis-understood of the classic design patterns. While it has a reputation as a slightly roundabout technique for doing simple processing on simple trees, it is actually an advanced tool for a specific use case: flexible, streaming, zero-overhead processing of complex data…
I'm a fan of Lisp programming languages, but there's an incredible conceptual elegance that struggles to materialise as readable elegance for many unfamiliar programmers. The underlying concepts are incredibly simple, but the learning curve can represent a disproportionate challenge.
A follow-along series of coding experiments as I explore Rust's peculiarities, from a C++ developer's perspective.
Like the blip of an intro on the front page says, my degree was originally in music. My running joke as a web dev is that neither has meaningfully required me to count past 32. And while my main concentration was vocals, I've since realized I should probably stop strictly calling this a nontechnical field, because my…
My Functional Programming journey was filled with dead ends, false starts, failed attempts and frustration. And I suspect that I’m not…
TIL: `satisfies` is my favorite TypeScript keyword
In Rust in 2023, @nrc floated an idea of a Rust compiler rewrite. As my hobby is writing Rust compiler frontends (1, 2), I have some (but not very many) thoughts here! The post consists of two parts, covering organizational and technical aspects.
Ever wonder about that mysterious Content-Type tag? You know, the one you’re supposed to put in HTML and you never quite know what it should be? Did you ever get an email from your friends in…
This document comes with a companion example program, available as one file or as multiple files (zipped) .
Sometimes a pure Python script can't just deliver the performance we need. When that's the case we have to resort to writing our logic in a "fast" compiled language like C or Rust and expose the function with through a Python module. This way we get the best of both worlds. Today I focus on how to use Rust for writing…

My plans for Go 1.20 include landing the crypto/ecdh package, making progress on moving math/big out of the security perimeter, and a batch of crypto/tls work.
People in the programming language design community strive to make their languages more expressive, with a strong type system, mainly to increase ergonomics by avoiding code duplication in final software; however, the more expressive their languages become, the more abruptly duplication penetrates the language itself.
In my book Understanding the Odin Programming Language I wrote that “Odin incorporates some of my favorite C best practices, straight into the language”. But I didn’t really elaborate on the details. Let’s do that here! This brings me to talking a bit about a previous job I had. Back in 2021 I worked at a place called…
I was introduced to Rust in 2018 and has been enamored since. Rust is a system programming language, much like C++. Unlike C++ though, being relatively new, its language design is more modern and sophisticated. Writing with can feel more like writing TypeScript or Haskell. Not surprising since, despite being a…
I had a vague idea that closures could have a variety of performance implications; I did not believe that so many of the chosen and potential designs for C and C++ extensions ones, however, were so…
Looking back at my year of Rust. Part reflection, part waymark.
Last week I’ve self-published my first book called “Writing An Interpreter In Go”, which you can get at interpreterbook.com . I want to tell you a little bit about why I chose to write this particular book.
