+Title: Latest Jami back in Debian Testing, and scriptable using dbus
+Tags: english, debian, sikkerhet, surveillance
+Date: 2021-01-12 17:00
+
+<p>After a lot of hard work by its maintainer Alexandre Viau and
+others, the decentralized communication platform
+<a href="https://en.wikipedia.org/wiki/Jami_(software)">Jami</a>
+(earlier known as Ring), managed to get its latest version into Debian
+Testing.  Several of its dependencies has caused build and propagation
+problems, which all seem to be solved now.</p>
+
+<p>In addition to the fact that Jami is decentralized, similar to how
+bittorrent is decentralized, I first of all like how it is not
+connected to external IDs like phone numbers.  This allow me to set up
+computers to send me notifications using Jami without having to find
+get a phone number for each computer.  Automatic notification via Jami
+is also made trivial thanks to the provided client side API (as a DBus
+service).  Here is my bourne shell script demonstrating how to let any
+system send a message to any Jami address.  It will create a new
+identity before sending the message, if no Jami identity exist
+already:</p>
+
+<p><pre>
+#!/bin/sh
+#
+# Usage: $0 <jami-address> <message>
+#
+# Send <message> to <jami-address>, create local jami account if
+# missing.
+#
+# License: GPL v2 or later at your choice
