Type-safe HTML templating in Zig
I’ve done a lot of web development over the years. I started around the year 2000, just after PHP 3.0 was released and started taking over the web world. I’ve used all kinds of approaches for generating HTML: raw PHP, string concatenation in Python, Smarty templates in PHP, Template Toolkit in Perl, and Jinja/Django…

C++ std::move doesn't move anything: A deep dive into Value Categories
Why std::move is just a cast, how it kills RVO if used wrong, and the mechanics of ownership transfer.

How to make a fast dynamic language interpreter
This post is about optimizing an extremely simple AST-walking interpreter for a dynamic language called Zef that I created for fun to the point where it is competitive with the likes of Lua, QuickJS, and CPython.

An incoherent Rust
Coherence and the orphan rules are a frequent source of complaints about Rust, and a common topic of language proposals. This post covers most of the existing proposals around coherence and my vision for how we should solve coherence once and for all.

An agent in 100 lines of Lisp
Around 2000 I took an AI course at the University of Guelph. I don’t think I learned too much. We didn’t talk about neural networks, as far as I can remember. My end of term project was, I think, a pathfinding algorithm wearing an AI costume. There were certainly no discussions of transformers. No CUDA. No PyTorch…

Swift at Apple: Migrating the TrueType hinting interpreter
TrueType is a widely used vector font standard for rendering text in web pages, PDFs, operating systems, and applications. Familiar fonts like Helvetica, Garamond, and Monaco are all built on TrueType outlines. The format specifies a hinting interpreter intended to help outlines rasterize faithfully on low-resolution…

RE#: how we built the fastest regex engine in F#
around a year ago, we built a regex engine in F# that not only outperformed the ones in dotnet, but went above and beyond competing with every other industrial regex engine on a large set of industry-standard benchmarks. it also supports the full set of boolean operators (union, intersection, complement) and even a…

The Mojo language (by Modular, now Qualcomm) is now open-source
Four and a half years ago, Modular made a bet: AI would not run on one kind of silicon forever, and the software stack would need to be rearchitected for a world of heterogeneous hardware and increasingly complex AI workloads.

sp.h: Fixing C by giving it a high quality, ultra portable standard library
Over the past year, I’ve been working on fixing C by giving it a high quality, ultra portable standard library. It is not a simple wrapper on top of libc; it doesn’t depend on libc except when required to by the platform. To my knowledge, there is nothing like it.

Some C habits I employ for the modern day
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…
