Regex engine internals as a library
Over the last several years, I’ve rewritten Rust’s regex crate to enable better internal composition, and to make it easier to add optimizations while maintaining correctness. In the course of this rewrite I created a new crate, regex-automata , which exposes much of the regex crate internals as their own APIs for…

Useless Use of "dd" (2015)
tl;dr: dd works for reading and writing disks, but it has no "low level I/O" capabilities that make it more suited for this than any other shell utility. Like cat you should use it where it makes sense, e.g. to take advantage of its wide array of options, rather than try to ensure that all disk related commands begin…

Batteries included with Emacs (2020)
Emacs has a reputation for being borderline unusable out of the box, of being bloated but somehow surprisingly bare. This is largely a discoverability problem1. The solution the Internet has settled on seems to be “Emacs distributions” like Doom, Spacemacs or Prelude that glue together dozens (sometimes hundreds) of…

Vale's first prototype for immutable region borrowing
Three years, two states, and one pandemic ago, I wrote about a very weird idea: what if the type system could track which data existed before a pure call, to eliminate its memory safety overhead? 0

Let's build a full-text search engine
Full-Text Search is one of those tools people use every day without realizing it. If you ever googled "golang coverage report" or tried to find "indoor wireless camera" on an e-commerce website, you used some kind of full-text search.

Audio Processing for Dummies
In my spare time I’m an emergency services volunteer, and one of the tasks our unit has is to run the radio network and keep track of what’s happening. This can be a pretty stressful job, especially when there’s lots of radio traffic, and it’s not unusual to miss words or entire transmissions. To help with a personal…
