Since my last post on monocles, I've got into the XMPP also known as jabber rabbit hole, here are few things I learned that you might find useful.

What is XMPP

The architecture of the XMPP network is similar to email, while a XMPP server conforms an email server (server.com) and XMPP clients conforms email clients ([email protected]). The difference is that everything happens in realtime over a persistent XML-TCP stream. The XMPP protocols are free & public, that any of us can use.

Differences with other communication services

It's one of the few actually decentralized communication platforms, there is no default server to join like in matrix.org. In a group chat with 100 people don't be surprised that all 100 of them belong to different servers
Hacker friendly & knowledgeable communities that are usually friendly
Easy to setup transports/gateways (similar to bridges) between different networks, such as IRC or even proprietary ones like whatsapp.

Self hosting a server

Self hosting xmpp is really simple, I personally opted for ejabberd and it only took ~10 minutes to set it up with voice & video call support.

Other options for servers are available here

Joining a server
