About Me

I am a software developer and data science student interested in civic technology. I am currently pursuing a master's degree at the University of Chicago in Computational Analysis and Public Policy. In my free time, I like to write about computer history and why the software we use every day works the way it does.

I am looking for work! If you think you could use my skills, please reach out. I graduate in June.


Two-Bit History

This is my blog about the history of computing and in particular the history of software development. There is a lot of writing out there about A) vintage computers and B) Silicon Valley's seminal corporate triumphs. But what about important questions like Where did JSON come from? or Why are man pages still a thing?

My history of the RSS standard was published by Vice News. Another article I wrote about the rendering technology in DOOM was republished by Ars Technica.

I was also interviewed for the podcast Secret History of the Future, which is jointly produced by Slate and The Economist.

A command-line utility to create and manage a parallel set of man pages—except these man pages, rather than being incomprehensibly dense, are your notes on how a program works. Now available in Homebrew/Core!
