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…

Sync Engines Are the Future
We've been building frontends that talk to backends for years. But in the meantime the browser has become an OS. In that case what should your stack look like?

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…

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…

Use Your Type System
Today I'm discussing a trivially simple technique that I've rarely seen used in production codebases. In programming, we often need to deal with simple values that can be represented by simple, generic types built into our programming language or provided by libraries: types like integer, string, or UUID. In any

The Journey Before main()
A while back, I worked on a RISC-V-based userspace simulator for fun. In doing so, taught myself a lot more than I wanted to know about what happens in-between when the Kernel is asked to run a program, and when the first line of our program’s main function is actually executed. Here’s a summary of that rabbit hole.
