Francisco Carvalho

Hi, I'm Francisco. Most people online know me as xiq. I build open tools that help online communities see themselves and find each other. Most of that happens at the Community Archive and in the lab around it, Epistemic Garden.

a. projects

Community Archive

An open, public archive of tweets donated by the people who wrote them. It holds 27 million tweets from 2,400 members, with an API, a daily bulletin, and agent search across the whole corpus.

The archive's map: 70,000 accounts in 38 neighbourhoods, placed by who talks to whom. Explore it live

2024–now · the paper on arXiv · the postrat canon

Epistemic Garden

The lab that holds the archive. We study how ideas spread, and we build coordination tools from what we learn: the bulletin, agent search, and opportunity mining and matching, which we are building with Cuties, where the network for it already exists.

e. background

My work is funded by Vitalik Buterin, the Survival and Flourishing Fund, Lightcone and Peter Wang.

Before that I worked at METR, Magic AI and the EU AI Office.

f. interests

The history of computers, and history in general. Phenomenology, and explaining the mystical in the vocabulary of computer science. Network science. Open data and open protocols.

I play guitar in GNU, a punky math rock trio with two records out. I dance, and I do contact improv and acro yoga.
