When Intel released the 80386 in October 1985, it marked a watershed moment for personal computing. The 386 was the first 32-bit x86 processor, increasing the register width from 16 to 32 bits and vastly expanding the address space compared to its predecessors. This wasn't just an incremental upgrade—it was the…
Why fixing package managers is harder than it looks.
Atwood's Law predicted JavaScript's dominance through accessibility. A new corollary is emerging: system languages will win through operational efficiency and AI-assisted development.

I got asked a good question today: what is the difference between Tree-sitter and a language server ? I don’t understand how either of these tools work in depth, so I’m just going to explain from an observable , pragmatic point of view.
Today, we will meet a spiky-haired nerd named Corey Dumm, who normally lives within Markdown code fences. We will get to know him a bit, smile with him when his fences hold and weep quietly when misfortune strikes.
I feel like I got substantial value out of Claude today, and want to document it. I am at the tail end of AI adoption, so I don't expect to say anything particularly useful or novel. However, I am constantly complaining about the lack of boring AI posts, so it's only proper if I write one.
Update: I've since added multithreading and pushed astroz to 326M propagations/sec. Read the follow-up → I've spent the past month optimizing SGP4 propagat...
A comprehensive guide to 113 production-informed patterns for building reliable AI agents.
Archiving 104K files into tar.gz reduced I/O time by 43x and total processing time by 2.3x. The bottleneck was not disk speed, it was syscall overhead.
How to run Claude Code with the `--dangerously-skip-permissions` flag in a safe way
Radio buttons are built into web browsers. Why are we using a UI library that wraps another UI library that rebuilds radio buttons from scratch? Why does rendering a radio button require multiple dependencies and several kilobytes of JavaScript? How did we make a built-in browser control so complicated?
New with expressions, type-safe error checking, and faster everything.
Wilson Lin at Cursor has been doing some experiments to see how far you can push a large fleet of "autonomous" coding agents: This post describes what we've learned from …
A floating point number f has the form f = m · 2 e where m is called the mantissa and e is a signed integer exponent . We like to read numbers scaled by powers of ten, not two, so computers need algorithms to convert binary floating-point to and from decimal text. My 2011 post “ Floating Point to Decimal Conversion is…
I've recently tasted AMD Zen 5 CPUs (AWS' m8a instances) and... Whooaaa. Even before talking about GPUs and NPUs, the next 5 years of CPUs will be very exciting! For
Despite it being the first “proper” programming language I learned—by reading K&R front-to-back no less—I don’t write C too terribly often nowadays. Playing resonite has gotten me into writing a load of C# for modding the game, and most of what I do day-to-day is automating the tedium on my computer, which gets…
When code execution really is all you need. Exploring what happens when an AI agent can only write and run code.
The bottleneck has shifted from implementation to specification.
A look at how I used shape vectors to achieve sharp, high-quality ASCII rendering.
Back pressure for agents You might notice a pattern in the most successful applications of agents over the last year. Projects that are able to setup structure around the agent itself, to provide it with automated feedback on quality and correctness, have been able to push them to work on longer horizon tasks. This…
Learn what a unikernel is and how it compares to a Linux container. Build and run your first unikernel inside a playground box.
It's not my favorite language
Why should anyone care about low-level programming?

Sharing a reluctant, "node & postgres" approach to engineering management for early-stage startups
A lot of people want to make a website but don’t know where to start or they get stuck. That’s in part because our perception of what websites should be has changed so dramatically over the last 20 years.
A few years ago, I wrote a blog post on design issues in LLVM IR . Since then, one of these issues has been fixed fully (opaque pointers migration), one has been mostly fixed (constant expression removal), and one is well on the way towards being fixed (ptradd migration).
DeepSeek replaced standard residuals with massive Hyper-Connections, and then watched them explode. I reproduced the 9x signal amplification to understand their fix: the Sinkhorn-Knopp algorithm. Part 1 of 2.
