   5 <p>After a lot of hard work by its maintainer Alexandre Viau and
   6 others, the decentralized communication platform
   7 <a href="https://en.wikipedia.org/wiki/Jami_(software)">Jami</a>
   8 (earlier known as Ring), managed to get
   9 <a href="https://tracker.debian.org/pkg/ring">its latest version</a>
  10 into Debian Testing.  Several of its dependencies has caused build and
  11 propagation problems, which all seem to be solved now.</p>
  12
  13 <p>In addition to the fact that Jami is decentralized, similar to how
  14 bittorrent is decentralized, I first of all like how it is not
  15 connected to external IDs like phone numbers.  This allow me to set up
  16 computers to send me notifications using Jami without having to find
  17 get a phone number for each computer.  Automatic notification via Jami
  18 is also made trivial thanks to the provided client side API (as a DBus
  19 service).  Here is my bourne shell script demonstrating how to let any
  20 system send a message to any Jami address.  It will create a new
  21 identity before sending the message, if no Jami identity exist
  22 already:</p>

  24 <p><pre>
  25 #!/bin/sh
  26 #
  27 # Usage: $0 <jami-address> <message>
  28 #
  29 # Send <message> to <jami-address>, create local jami account if
  30 # missing.
