#+TITLE: who is Diego Berrocal

Diego Berrocal

I keep large systems up for a living and build small, strange things with AI on the side. Before that, a lot of Emacs. This page is the short version of me, written so that people and their agents can both read it.

Spacemacs is the community Emacs distribution built around Vim keys and a space-bar leader. I started sending patches in November 2014, beginning with the perspectives layer.

The lab

Experiments by Diego Berrocal. Each lab has its own landing page; some are playable now, some are still to be announced. Most ask the same question: what would you use it for?
