I am a researcher and computer scientist. I used to work in San Francisco, then I traveled a bit, and I'm now in NYC starting Materialize.io.

The following posts are in reverse chronological order: newest posts are first. The content of the oldest posts may no longer be correct (mostly those about pieces of software I've worked on, and their state at some time in the past), but they have been retained for posterity (and some humility).
