From Rust to Ruby
Who does things like that?!? Apparently: me. I have my own project, written in Rust. Not a big one, mind you, maybe approx. 30k lines of code in total. Rust is verbose so it’s not really that impressive. I’ve put it aside for some time and was toying with local inference, LLMs, writing agents and my attention was…

Raft Consensus with a Minority of Nodes
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…

A New Typst Template for Pandoc (2025)
Last summer I spent a lot of time with Typst (at that point v0.11) and Pandoc, working on a flexible and reusable workflow to typeset markdown-formatted articles to PDF. I designed a Pandoc template for Typst that would do nice things with layout and typography, and I posted about that here .

Using AI to write better code more slowly
A lot of people seem convinced that the point of AI coding is to write low-quality code as fast as possible. Spew out barely-passable slop, open massive PRs,…

C extensions, portability, and alternative compilers
Anyone who's written C knows that full ISO C standard-adhering code is an impractical rarity. Most real world C code out there relies on non-standard behaviors and language extensions to varying extents, and a lot of this isn't for extra features, but just to work around bugs and gaps in different compilers and…

C array types are weird
C array types are weird. In this article I’ll explain what I find weird about them, what I’d do differently, and ramble on a few related things.

Jira Is Turing-Complete
Engineering folklore holds that Jira (Atlassian's project-tracking tool) is Turing-complete . Existing claims point vaguely at automation features without exhibiting a reduction. This article supplies a proof, with setup instructions and execution trace.

Migrating from Go to Rust
Out of all the migrations I help teams with, Go to Rust is a bit of an outlier. It’s not a question of “is Rust faster?” or “does Rust have types?”, Go already gets you most of the way there. The discussion is mostly about correctness guarantees, run…

Claude is not your architect. Stop letting it pretend
Somewhere between 'ask Claude for a quick opinion' and 'Claude is writing our Jira tickets,' we lost the plot. AI agents are brilliant implementers. They're also confidently wrong about every decision that matters. And when it all falls over, they won't be the ones carrying the bag.

What it takes to transpose a matrix
Classical CPU architecture is a poor choice for performing matrix-oriented computations. Developers have to spend much effort to create efficient algorithms even for the problems appearing trivial on the surface. Matrix transpose is probably the most striking representative of such problems. It exposes numerous…

My I3-Emacs Integration
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…

Don't Roll Your Own
This is going to be a rant about modern web design practices. But before I get to that, let me begin with a familiar principle from the world of cryptography. Among software developers, and especially among those who work on security-sensitive systems, there is a well-known maxim: Don't roll your own crypto. This does…

z386: An Open-Source 80386 Built Around Original Microcode
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 .

Making deep learning go brrrr from first principles (2022)
So, you want to improve the performance of your deep learning model. How might you approach such a task? Often, folk fall back to a grab-bag of tricks that might've worked before or saw on a tweet. "Use in-place operations! Set gradients to None! Install PyTorch 1.10.0 but not 1.10.1!"

A blueprint for formal verification of Apple corecrypto
With the latest release of corecrypto, we’re publishing our implementations of quantum-secure ML-KEM and ML-DSA algorithms, along with the mathematical proofs we built to assure they are faithful to the FIPS 203 and FIPS 204 specifications. To advance the state of the art for assuring critical software, we're also…
