I was recently encouraged to watch A Practical Guide to Applying Data Oriented Design (DoD) by Andrew Kelley, the creator of Zig1. Just 10 minutes into the talk, I was confronted with a skill I had never formally learned… the arithmetic behind memory layout of types. Zig is a modern, C-like programming language which…
Raft is a consensus protocol for managing a replicated log across a cluster of nodes. Its key goals are: (1) maintain a consistent replicated log of state transitions, (2) tolerate node failures, and (3) ensure a single leader coordinates all changes while multiple followers replicate. Raft is designed to be…
One of the most surprising aspects of the Nix language is that it is lazy, especially if you have never used a lazy language before. This laziness is what makes much of Nixpkgs possible, and its complexity.

In mid-December last year I started making my own programming language. It's waaay far from any production quality yet (though I did manage to write a working 1k LOC Monte-Carlo path tracer in it), but the project is on pause right now, so I figured it's a good time to write something about it.
2. Functions delay binding; data structures induce binding. Moral: Structure data late in the programming process.
I have too many git branches and like many people I developed a convoluted script to show me the most recent ones. I ran this command many times a day for years:
There are a few different reasons to hit the brakes on a Postgres query. Maybe it’s taking too long to finish. Maybe you realised you forgot to create an index that will make it orders of magnitude quicker. Maybe there’s some reason the results are no longer needed. Or maybe you, or your LLM buddy, […]
I generally avoid messing with Li-ion battery packs, but these are both Ni-mh and expensive.
Made in Notion, the connected workspace where AI agents and teams organize docs, projects and knowledge together.
Typed decisions with a probability for every option, from GLM-5.3-Flash in a single forward pass: about as accurate as Jev, faster from Europe, and protected by confidential computing. With a playground and a benchmark on 29 datasets.
tiling window managers are wonderful. ultra-flexible text editors are also wonderful. for a spell, i thought i'd found the ideal solution in exwm … and i think it would have been, save for the fact that i use ordinary, graphical windows as much, if not more than, text buffers, and sometimes those windows are from…
A math solver leads to encrypted code in npm packages. Follow the loader, the trigger matrix that unlocks it, the remote access payload, and the full indicators.
System composition and other interfaces for Biff projects
The optimizations behind Wasmi 2.0, and how they compare to Wasm3 and Stitch.
Many legends of software development, like John Carmack or Chris Lattner, are very approachable. Check out their projects and go talk to them!
It will ask you hunk by hunk for the things to include in the first commit, and then bring up the editor for the first and second commit message. It couldn’t be simpler than that.
Using Oban to seamlessly exchange durable jobs between Elixir and Python applications through a shared PostgreSQL database.
It had been there long before Windows 95, but nobody remembered.
how to hide juicy data in plain sight
A tour of the-stats-duck v0.6.0: a one-shot data profiler, regression and bootstrap CIs in plain SQL, ten new distributions, and SAS/XPT imports that got 52x faster — with live Bedevere demos you can poke at.
This release will be the Reference Implementation of version 28 of the Java SE Platform, as specified by JSR 403 in the Java Community Process.
Recently, while working on an optimized Quicksort implementation, I came across a rather interesting quirk. Modern compilers (especially Clang) optimize loops using fast, branch-free instructions - provided you use the right programming style.
The trick that makes GHC’s ApplicativeDo optimization faster is structurally identical to how biologists predict RNA folding.
Over the course of four weeks in January and February, I built a new programming language using Claude Code. I named it Cutlet after my cat. It’s completely legal to do that. You can find the source code on GitHub , along with build instructions and example programs .
My friend and I have a game where we talk about what we'd do if we were rich. Not rich like 'paid off the mortgage' rich. Rich like a man who owns a submarine he's never been inside. Rich like a man whose third wife has a skincare
this is an incomplete list of some incompatibilities between c as it's written in the standard and c as it exists in the real world for people who use gcc/clang + glibc/musl.
Today, we are thrilled to announce the release of Angular v22. We continue to be proud of the work we do with each release. Our goal is to…
