Projects and Stuff

An open-source IDE I built for working with many coding agents at once. Works with all major coding agents, letting you manage multiple agents across worktrees, monitor their progress, and coordinate complex workflows from a single interface.

A browsable archive of all book and non-book reviews submitted to the annual Astral Codex Ten review contest. Searchable, organized by topic, and tracks your reading progress.

An interactive visualization of US, British and World history, including a graph of changes in world power. Inspired by John B Sparks' original 1931 Histomap.

A command-line tool to make it easier to work with multiple Git worktrees. Particularly useful when managing multiple coding agents

Slowpost is the social network where you can only post once a year. Or to put it another way, it's a simple app for managing the subscribers for your annual email.

Ever wondered what the difference is between different beer styles and why they taste different? A simple PDF I created for a beer tasting party

Working with an international consortium of public broadcasters to create a publicly owned, public-interest online space. I was the founding engineer, and designed the core architecture.

I joined Meta (then Facebook) in the aftermath of the 2016 US election to help them work out what to do about polarization and misinformation. I defined metrics, improved comment ranking, and led a team to understand fundamental drivers.

I was the founding Product Manager of Featured Snippets, which gave direct answers to user queries by quoting web content. This was a particularly fun project to work on because it meant working with the research team that would go on to invent transformers.

I represented Intel in the HTML5 Working Group, helping define the standard that turned the web from a document format into an application platform.

Developed one of the first systems to automatically identify online misinformation.
