What is “good taste” in software engineering?
Technical taste is different from technical skill. You can be technically strong but have bad taste, or technically weak with good taste. Like taste in general…

I'll think twice before using GitHub Actions again
The blog post discusses dissatisfaction with GitHub Actions due to its limitations in managing complex workflows, especially in monorepo setups with certain features like pull request checks and workflow reusability. Several issues have been highlighted, along with alternatives for GitHub Actions.

How I blog with Obsidian, Hugo, GitHub, and Cloudflare
I’ve been using Obsidian for all my writing lately, and it’s been a game changer. The local-first model means everything lives as plain text on my machine, and with the Minimal theme, the interface stays clean and distraction-free. My vault lives in iCloud (Dropbox or Google Drive work too), so notes sync seamlessly…

Rv, a new kind of Ruby management tool
For the last ten years or so of working on Bundler, I’ve had a wish rattling around: I want a better dependency manager. It doesn’t just manage your gems, it manages your ruby versions, too. It doesn’t just manage your ruby versions, it installs pre-compiled rubies so you don’t have to wait for ruby to compile from…

Erlang's not about lightweight processes and message passing (2023)
I used to think that the big idea of Erlang is its lightweight processes and message passing. Over the last couple of years I’ve realised that there’s a bigger insight to be had, and in this post I’d like to share it with you.

I Wrote a WebAssembly VM in C
For the last 6 months, I’ve been spending my (limited) free time on evenings and weekends writing a WebAssembly VM in C. After repeatedly throwing away small side-projects, this was an extremely productive experience for me as an engineer. I’m writing this in order to put together some take-aways and organize my…

How I turned Zig into my favorite language to write network programs in
I’ve been watching the Zig language for a while now, given that it was created for writing audio software (low-level, no allocations, real time). I never paid too much attention though, it seemed a little weird to me and I didn’t see the real need. Then I saw a post from Andrew Kelley (creator of the language) on…

Python can run Mojo now
Chris Lattner mentioned that Python can actually call Mojo code now. I love this idea (!) as I'm definitely in the market for a simple compiled language that can offer Python some really fast functions.

Git without a forge
I’ve written quite a lot of free software in my life. Most of it was from scratch: projects I started myself. So I get to choose where to host them – or rather, I have to choose where to host them.

Beware of Fast-Math
One of my more frequent rants, both online and in person, is the danger posed by the "fast-math" compiler flag. While these rants may elicit resigned acknowledgment from those who already understand the dangers involved, they do little to help those who don't. So given the remarkable paucity of writing on the topic…

Why are QR Codes with capital letters smaller than QR codes with lower case?
Take a look at these two QR codes. Scan them if you like, I promise there's nothing dodgy in them. Left is upper-case HTTPS://EDENT.TEL/ and right is lower-case https://edent.tel/ You can clearly see that the one on the left is a "smaller" QR as it has fewer bits of data in it. Both go to the same URl, the only…

TinyCompiler: A compiler in a week-end
Have you ever wondered how a compiler works, but you never found courage to find out? Then this series of articles is for you. I have never had the chance to look under the hood either, but one week-end I have decided to to write a translator from the esoteric programming language wend (short for week-end), which I…
