Matrix self-hosting
I started running my own Matrix server a little while ago. Matrix is something rather cool, a chat system similar to IRC or Slack, but open and federated. Open in that the standard is available for anyone to view, but also the reference implementations of server and client are open source, along with many other clients and a couple of nascent alternative servers. Federated in that, like email, it doesn’t matter what server you sign up with, you can talk to users on your own or any other server.
