This series of articles is a tutorial on the theory and practice of developing language parsers and compilers. Before we are finished, we will have covered every aspect of compiler construction, designed a new programming language, and built a working compiler.
TLDR: Demo is at , code is at . The Problem When building a website or app using HTML Canvas, it’s often a requirement to support a flood fill. That is, when the user chooses a colour and cli…
I previously wrote about starting a Go project in 2018. A lot has changed since I wrote that and I had been wanting to write an updated version. What follows should be enough for anyone new to Go to …
PyPI has removed support for uploading PGP signatures with new releases.
Building UIs in HTML+CSS can be untenable. When making complex frontend experiences, I reach for Elm.
In this long article, I, being as far as I know the first outside Microsoft to have learnt how the AARD code works, explain that I condemn its form but broadly sympathise with its function.
A book I was recently reading mentioned a mathematical curiosity I haven't seen before - Tupper's self-referential formula . There are some resources about it online, but this post is my attempt to explain how it works - along with an interactive implementation you can try in the browser.
Introduced in 2019 (kernel 5.1) by Jens Axboe, io_uring (henceforth uring) is a system for providing the kernel with a schedule of system calls, and receiving the results as they're generated. Whereas epoll and kqueue support multiplexing, where you're told when you can usefully perform a system call using some set of…

In this blog post, I delve into the comparison of memory consumption between asynchronous and multi-threaded programming across popular languages like Rust, ...
It's been a hectic past few months for the project. In addition to the upcoming release on Steam, a lot of focus has gone into other major features. While not everything has landed yet, two very important changes to Android did arrive, one of which has been in the works for a couple years! We're talking about a large…
I’d like to share with you my latest project: Decktility!

We’re happy to announce the first release of Topiary, a formatter for many languages that leverages Tree-sitter.
TL;DR I’ve been working on a WebGPU optimized inference and autograd library called webgpu-torch with an API that matches PyTorch. The goal is to run neural networks in the browser at speeds comparable to a Linux workstation. Many kernels have been implemented and its design is easily extensible. It’s available on NPM…

The handbook to the LangChain library for building applications around generative AI and large language models (LLMs).
Earlier this year, I lost the ability to use a keyboard and mouse for extended periods. Fortunately, this wasn't as catastrophic as it sounds! This article chronicles my experience using adaptive tools like dictation and eye-tracking as my primary mechanisms for writing code.
Listen in on Jane Street’s Ron Minsky as he has conversations with engineers working on everything from clock synchronization to reliable multicast, build systems to reconfigurable hardware. Get a peek at how Jane Street approaches problems, and how those ideas relate to tech more broadly.
They provide a safety net when making changes, and give you that nice, warm feeling when you see them all pass after a change.
Made in Notion, the connected workspace where AI agents and teams organize docs, projects and knowledge together.
A way to talk about programming languages, and a plea to Think Different™
Bash is oft-maligned: you hear it sneered at in sentences like “our continuous integration pipeline is just a pile of bash scripts .” It is commonly regarded as unintelligible and thus unmaintainable. The pile of bash scripts are the toxic byproduct of an infrastructure team understaffed, pressed for time, unwilling…
