+ <description><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.

without success, so I decided I would have to live with this wart
until someone managed to fix the leak in the dring code base. But
another problem showed up once the rooms were password protected. I
consist of the room ID (a number), an @ character and the IP address
of the Zoom SIP gateway. But Zoom understand a lot more than just the
room ID in front of the at sign. The format is "<tt>[Meeting

can both enter password, control the layout (full screen, active
presence and gallery) and specify the host key to start the meeting.

recommend this setup to others. :)</p>

- <title>GnuCOBOL, a free platform to learn and use COBOL - nice free software</title>

- <description><p>The curiosity got the better of me when
-<a href="https://developers.slashdot.org/story/20/04/06/1424246/new-jersey-desperately-needs-cobol-programmers">Slashdot
-reported</a> that New Jersey was desperately looking for
-<a href="https://en.wikipedia.org/wiki/COBOL">COBOL</a> programmers,
-and a few days later it was reported that
-<a href="https://onezero.medium.com/ibm-rallies-cobol-engineers-to-save-overloaded-unemployment-systems-eeadf13eddce">IBM
-tried to locate COBOL programmers</a>.</p>
-
-<p>I thus decided to have a look at free software alternatives to
-learn COBOL, and had the pleasure to find
-<a href="https://sourceforge.net/projects/open-cobol/">GnuCOBOL</a> was
-already <a href="https://tracker.debian.org/pkg/gnucobol">in
-Debian</a>. It used to be called Open Cobol, and is a "compiler"
-transforming COBOL code to C or C++ before giving it to GCC or Visual
-Studio to build binaries.</p>
-
-<p>I managed to get in touch with upstream, and was impressed with the
-quick response, and also was happy to see a new Debian maintainer
-taking over when the original one recently asked to be replaced. A
-new Debian upload was done as recently as yesterday.</p>
-
-<p>Using the Debian package, I was able to follow a simple COBOL
-introduction and make and run simple COBOL programs. It was fun to
-learn a new programming language. If you want to test for yourself,
-<a href="https://en.wikipedia.org/wiki/GnuCOBOL">the GnuCOBOL Wikipedia
-page</a> have a few simple examples to get you startet.</p>
-
-<p>As I do not have much experience with COBOL, I do not know how
-standard compliant it is, but it claim to pass most tests from COBOL
-test suite, which sound good to me. It is nice to know it is possible
-to learn COBOL using software without any usage restrictions, and I am
-very happy such nice free software project as this is available. If
-you as me is curious about COBOL, check it out.</p>
