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 React Re-Renders
In React, we don't update the DOM directly, we tell React what we want the DOM to look like, and React tackles the rest. But how exactly does it do this? In this tutorial, we'll unpack exactly when and why React re-renders, and how we can use this information to optimize the performance of our React apps.

Using S3 as a Container Registry
For the last four months I’ve been developing a custom container image builder, collaborating with Outerbounds1. The technical details of the builder itself might be the topic of a future article, but there’s something surprising I wanted to share already: you can use S3 as a container registry! You heard it right…

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…

Develop the three great virtues of a programmer: laziness, impatience, and hubris
In computing, “laziness” is a broad term, generally referring to not doing any work unless you need it. Whereas its opposite is “eagerness,” doing as much work as possible in case you need it later.

I made a patch for Mozilla, and you can do it too
In this article, I will tell how I contributed code to Mozilla during a Bug Squashing Party. I hope to provide some tips and advice about how to start contributing to a Mozilla project (or any other open-source project). I will talk about Firefox and Servo, which, I think, are somehow representative of two common ways…

A 100x speedup with unsafe Python
We're going to speed up some numpy code by 100x using "unsafe Python." Which is not quite the same as unsafe Rust, but it's a bit similar, and I'm not sure what else to call it... you'll see. It's not something you'd use in most Python code, but it's handy on occasion, and I think it shows "the nature of Python” from…

A Real Life Off-by-One Error
The Championnats d’Europe d’Escalade (climbing) in Villars-sur-Ollon has just finished. I couldn’t make it to all the events, but did see the finals of the “Speed” event. It’s a series of head-to-head elimination races up a 15m tall wall, resulting in an eventual victor after enough rounds.
