In April 2026, Canonical disclosed 44 CVEs in uutils, the Rust reimplementation of GNU coreutils that ships by default since 25.10. Most of them came out of an external audit commissioned ahead of the 26.04 LTS. I read through the list and thought th…
Open Source before GitHub was reputation-driven and full of friction
The origin story of a 3D Modeler made very quickly
Hello! This post somehow got a lot of attention. Thanks for visiting! If you like it, it would be awesome if you’d check my app Findings, a …

“signed char lotte” is a computer program written by Brian Westley and the winner of the “Best Layout” award in the 1990 International Obfuscated C Code Contest. The cleverness of the text is staggering. Superficially it reads as an epistolary exchange between two (possibly former) lovers, Charlotte and Charlie. At…
Google's plans on making Swift the first mainstream language with first-class language-integrated differentiable programming capabilities. What's so cool about Swift?
Developing Opinions - A blog by Jimmy Breck-McKye
Vector embeddings have been an Overton window shifting experience for me, not because they’re sufficiently advanced technology indistinguishable from magic, but the opposite.
Take the following code: a = 1 a = a + 1 print(a) A common FP critique of imperative programming goes like this: “How can a = a + 1? That’s like saying 1 = 2. Mutable assignment makes no sense.” This is a notation mismatch: “equals” should mean “equality”, when it really means “assign”. I agree with this criticism and…
An updated generics design draft, and a translation tool for experimentation
Claude can now discover, learn, and execute tools dynamically to enable agents that take action in the real world. Here’s how.
In this post, I describe the phenomenon of the so-called expert beginner -- someone with mediocre skill who thinks he's an expert.
Muse Wonder is Meta's frontier AI model that keeps track of what matters to you with Active Memory & Active Focus to work towards your goals at work & life.
SIMD has a reputation for being complex. I've met many very good software engineers who dismiss it as something too complex to learn or a niche optimization meant for only the highest-performance software, not useful in everyday programming.
A Coherent Vision for the Future of Version Control
If you’re still using IP geolocation to decide what language to show, stop screwing around. It’s a broken assumption dressed up as a feature.
Deno 1.9 adds a new native HTTP/2 web server, a vastly improved op infrastructure, import completions in the LSP, an interactive permission prompt, blob url support.
Note: this post is also available in video format on YouTube . Some demo/ difference would be more obvious in video.
The other day, I saw a viral tweet saying that people talking about how LLMs are causing slow, bloated, code are going to eat crow once they re-write everything in super-optimized assembly. We're not quite at the point where we want to write everything in assembly , but some variant of what Nolan Lawson said about…
Brave Shields, which protect users’ privacy from trackers and ads, are one of the cornerstone components of the browser involved in handling every single web request made for loading a website.
This project is discontinued. The github repos are still available as archives, but no deployment is maintained and no PRs will be accepted. You can still join the Discord if you want but it is not active.
JSONB is a rewrite of the SQLite JSON functions that, depending on usage patterns, could be several times faster than the original JSON functions. This enhancement has now landed on trunk .
