I’m friends with a bunch of nerds, and we choose some unusual services to keep in touch.

For chatting, I run a Matrix server. It’s similar to private offerings from Slack and Discord, but is entirely federated and end-to-end encrypted.

I wrote a bot named Theorem that hangs out in our Matrix server and does some helpful things:

• Periodically posts the latest movies that are showing in nearby theaters
• Periodically posts upcoming volunteering events happening in nearby cities
• Posts a notification when folks are chatting in our voice server
• Posts a notification when folks are streaming video to our private streaming server

The source code is available on GitHub.
