In a previous post SIMD Matters I discussed the big wins I got from graph coloring to make the contact solver faster. That same approach exists in Box3D. I like to call this approach “wide SIMD”. The idea is to process multiple work units at the same time. In the contact solver this means solving four contact points…
This is the fifth installment of the 80386 series . The FPGA CPU is now far enough along to run real software, and this post is about how it works. z386 is a 386-class CPU built around the original Intel microcode, in the same spirit as z8086 .
I am talking about the I/O operations as used in computing here. A typical example of how this kind of thing is exposed are the POSIX syscalls read(2) and write(2), which have the following C funct…
In reply to this email:
C interpreters are a common language implementation technique and the basis for the reference implementations of languages such as Lua, Ruby, and Python. Unfortunately, C interpreters are slow, especially compared to language implementations powered by JIT compilers. In this post I’m going to show that it is possible…
When seeing the title of this post, I bet in some people's minds, the first thought was "Rust devs!". This connection is not unfounded. Rust devs tend to be passionate about memory safety. Some of it, I'm sure, may have been caused by a classic language wars attitude: my language is better than yours, and here is why…

Enjoy Emacs and its built-in language server (LSP) superpowers, for JVM languages. Let's walk through basic language setups, specialized workspace configuration handling, and dive deep into some advanced JSON-RPC and advice-based workarounds for Scala (Metals) and Kotlin that make development truly seamless from Emacs…
The best parts of Django are the ones you stop noticing — a tour of the abstractions that have given Buttondown the most leverage over the years.
Agents used to be a thing you talked to synchronously. Now they’re a thing that runs in the background while you work. When you make that change, the …
Unified code base. Upstream first. No fork. SoC agnostic. Learn how you can build with Qualcomm Linux 2.0
tapo now logs in over the TPAP protocol, so the Third-Party Compatibility switch in the Tapo app can stay off. Also new: H200 and H500 camera hubs with recording downloads, and plug schedules and timers.
Most linux software just work on FreeBSD
Back in November last year, I started a new job at Intercom, and one of the first projects I got to work on was improving the Intercom monolith CI with some of my new colleagues.
Here's an interesting bug I ran into recently: After transferring some files to my server via scp, I couldn't log in via SSH anymore - my key was rejected by sshd.
A real VLC video filter, ported line by line to C# and raced against the original C inside VLC 4, then optimized on both sides, with byte-identical output throughout.
LocalAI is the open source AI engine. Run any model, LLMs, vision, voice, image and video, on any hardware. No GPU required.

Measuring a commercial spatial audio processor, extracting its stereo impulse responses, and rebuilding the effect as a convolution filter on Linux.
I spent the summer at Recurse Center, a programming retreat in Brooklyn, at the recommendation of my friend Cory. These are some things I did there.
From a single pilot to an air campaign: planning, parallelism, memory, verification, and observability for production-shaped agents.
Writing, compiling, loading, and querying eBPF programs in one Lisp form.
Instead of just learning how to use a deep learning library, we are going to learn how to create one.
An interactive explaination of how QR codes work and techniques for rendering artistic QR codes
I’ve been going round and round in my mind about a particular discussion around LLMs: are they really similar to compilers? Are we headed toward a world where people don’t look at the underlying code for their programs?
Verily, some of our brethren (and sistren) be afflicted with a sinister disposition. While the righteous scroll using the thumb of their right hand - as is good and proper - an accurs'd minority swing the other way. Look, you try writing an interesting bug report without sounding like a clanker, OK! I try to optimise…
Scaling is a complex topic, but after working at big tech on services handling millions of requests and scaling my own startup (AlgoMaster.io) from scratch, I’ve realized that most systems evolve through a surprisingly similar set of stages as they grow.
We’re excited to announce that Google will launch Chrome for ARM64 Linux devices in Q2 2026, following the successful expansion of Chrome to Arm-powered macOS devices in…
