Enrico Zini, a Debian developer, writes practical notes on Linux administration, Python, Raspberry Pi and secure messaging setup.
HN links it for practical Linux fixes, like the Raspberry Pi 4 WiFi problem at 2560x1440, and for guides on XMPP and DebOps.
How many trustworthy and well administered XMPP servers are out there?
BTW, for anyone wanting to setup a modern XMPP server, check out this:

Personally I would use standard practices of the open source world; package your app properly into a .deb/.rpm, deploy that and push configuration for it out using puppet/ansible/etc. aka, debops!
