Discovering Dennis Ritchie’s Lost Dissertation
Until recently, across a half-century perhaps fewer than a dozen people had ever had the opportunity to read Dennis Ritchie’s dissertation—the intellectual and biographical fork-in-the-road separating an academic career in computer science from the one at Bell Labs leading to C and Unix. Why?

Programming with Categories
In this course we explain how category theory—a branch of mathematics known for its ability to organize the key abstractions that structure much of the mathematical universe—has become useful for writing elegant and maintainable code. In particular, we'll use examples from the Haskell programming language to motivate…

Stupid solutions: Live server push without JS
So in my post Is this evil? I covered a way of tracking users with CSS. While thinking about those weird ways of using the web I also started thinking about pushing live data to clients without JS. Or at least maintaining a connection. So WebSockets requires JS. WebRTC requires JS. Even HLS (video streaming), which…

Zlib-rs is faster than C
We've released version 0.4.2 of zlib-rs , featuring a number of substantial performance improvements. We are now (to our knowledge) the fastest api-compatible zlib implementation for decompression, and beat the competition in the most important compression cases too.

What's Functional Programming All About?
There are many descriptions floating around the internet, trying to explain functional programming in simple terms. Unfortunately, most discuss details only loosely related to functional programming, while others focus on topics that are completely irrelevant. So of course, I had to write my own!

A Review of the Zig Programming Language (Using Advent of Code 2021)
I’ve long thought that Zig was an interesting programming language, potentially more interesting than Rust in many respects given that Zig seems to be targetting a more modern C-like language replacement whereas Rust firmly looks like it is trying to take C++ out back like ol’ yeller. Rust is powerful, but the…

Textmate 2 - Alpha this year
There has been a lot of speculation and trepidation about the future of TextMate recently, mostly about whether there will be another major release. Work on 2.0 began and while we wish it could have been completed faster we are very pleased with how it is turning out. Development has reached a point finally where we…

Why am I interested in Elixir?
I’ve had Elixir on the brain recently. And by recently I probably mean 2 years. In my defense I think it is fair to say it is blooming right now. I haven’t had much need of it, or opportunity for it, in my day-to-day of maintaining a Python legacy system, renewing another legacy or optimizing Elasticsearch. So I’ve…

OpenClaw is changing my life
I want to share some thoughts on my recent experience with OpenClaw. Over the past year, I’ve been actively using Claude Code for development. Many people believed AI could already assist with programming—seemingly replacing programmers—but I never felt it brought any revolutionary change to the way I work. Sure…
