My name's Jakob, and I'm a self-taught free software hacker. I'm into computer security, software verification, functional programming, and lifting weights.

That's the short version. I have a longer biography available here, and a page describing what I'm focused on at this point in my life available here.

If you've sent an email to an address of mine ending in 'sdf.lonestar.org' between January 2nd, 2020 and now, I have not received it. SDF has discontinued mail service on that domain. Accordingly, I have a new PGP key.

To the best of my knowledge, access to this website is not being blocked by any foreign government. Should this change, I maintain mirrors on Tor and i2p.

1: I'll just ask that you reach out to me through other channels before sending me an invitation on Jabber. My address ended up on the XSender list, so I have a script to block messages from anyone not on my roster.
