+               <description>&lt;p&gt;The curiosity got the better of me when
+&lt;a href=&quot;https://developers.slashdot.org/story/20/04/06/1424246/new-jersey-desperately-needs-cobol-programmers&quot;&gt;Slashdot
+reported&lt;/a&gt; that New Jersey was desperately looking for
+&lt;a href=&quot;https://en.wikipedia.org/wiki/COBOL&quot;&gt;COBOL&lt;/a&gt; programmers,
+and a few days later it was reported that
+&lt;a href=&quot;https://onezero.medium.com/ibm-rallies-cobol-engineers-to-save-overloaded-unemployment-systems-eeadf13eddce&quot;&gt;IBM
+tried to locate COBOL programmers&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;I thus decided to have a look at free software alternatives to
+learn COBOL, and had the pleasure to find
+&lt;a href=&quot;https://sourceforge.net/projects/open-cobol/&quot;&gt;GnuCOBOL&lt;/a&gt; was
+already &lt;a href=&quot;https://tracker.debian.org/pkg/gnucobol&quot;&gt;in
+Debian&lt;/a&gt;.  It used to be called Open Cobol, and is a &quot;compiler&quot;
+transforming COBOL code to C or C++ before giving it to GCC or Visual
+Studio to build binaries.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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,
+&lt;a href=&quot;https://en.wikipedia.org/wiki/GnuCOBOL&quot;&gt;the GnuCOBOL Wikipedia
+page&lt;/a&gt; have a few simple examples to get you startet.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;

-               <description>&lt;p&gt;Four years ago, I did a back of the envelope calculation on
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/What_would_it_cost_to_store_all_phone_calls_in_Norway_.html&quot;&gt;how
-much it would cost to store audio recordings of all the phone calls in
-Norway&lt;/a&gt;, and came up with NOK 2.1 million / EUR 250 000 for the
-year 2013.  It is time to repeat the calculation using updated
-numbers.  The calculation is based on how much data storage is needed
-for each minute of audio, how many minutes all the calls in Norway
-sums up to, multiplied by the cost of data storage.&lt;/p&gt;
-
-&lt;p&gt;The number of phone call minutes for 2018 was fetched from
-&lt;a href=&quot;https://ekomstatistikken.nkom.no/&quot;&gt;the NKOM statistics
-site&lt;/a&gt;, and for 2018, land line calls are listed as 434 238 000
-minutes, while mobile phone calls are listed with 7 542 006 000
-minutes.  The total number of minutes is thus 7 976 244 000.  For
-simplicity, I decided to ignore any advantages in audio compression the
-last four years, and continue to assume 60 Kbytes/min as the last
-time.&lt;/p&gt;
-
-&lt;p&gt;Storage prices still varies a lot, but as last time, I decide to
-take a reasonable big and cheap hard drive, and double its price to
-include the surrounding costs into account.  A 10 TB disk cost less
-than 4500 NOK / 450 EUR these days, and doubling it give 9000 NOK per
-10 TB.&lt;/p&gt;
-
-&lt;p&gt;So, with the parameters in place, lets update the old table
-estimating cost for calls in a given year:&lt;/p&gt;
-
-&lt;table border=&quot;1&quot;&gt;
-&lt;tr&gt;&lt;th&gt;Year&lt;/th&gt;&lt;th&gt;Call minutes&lt;/th&gt;&lt;th&gt;Size&lt;/th&gt;&lt;th&gt;Price in NOK / EUR&lt;/th&gt;&lt;/tr&gt;
-&lt;tr&gt;&lt;td&gt;2005&lt;/td&gt;&lt;td align=&quot;right&quot;&gt;24 000 000 000&lt;/td&gt;&lt;td align=&quot;right&quot;&gt;1.3 PiB&lt;/td&gt;&lt;td align=&quot;right&quot;&gt;1 170 000 / 117 000&lt;/td&gt;&lt;/tr&gt;
-
-&lt;tr&gt;&lt;td&gt;2012&lt;/td&gt;&lt;td align=&quot;right&quot;&gt;18 000 000 000&lt;/td&gt;&lt;td align=&quot;right&quot;&gt;1.0 PiB&lt;/td&gt;&lt;td align=&quot;right&quot;&gt;900 000 / 90 000&lt;/td&gt;&lt;/tr&gt;
-
-&lt;tr&gt;&lt;td&gt;2013&lt;/td&gt;&lt;td align=&quot;right&quot;&gt;17 000 000 000&lt;/td&gt;&lt;td align=&quot;right&quot;&gt;950 TiB&lt;/td&gt;&lt;td align=&quot;right&quot;&gt;855 000 / 85 500&lt;/td&gt;&lt;/tr&gt;
-
-&lt;tr&gt;&lt;td&gt;2018&lt;/td&gt;&lt;td align=&quot;right&quot;&gt;7 976 244 000&lt;/td&gt;&lt;td align=&quot;right&quot;&gt;445 TiB&lt;/td&gt;&lt;td align=&quot;right&quot;&gt;401 100 / 40 110&lt;/td&gt;&lt;/tr&gt;
-&lt;/table&gt;
-
-&lt;p&gt;Both the cost of storage and the number of phone call minutes have
-dropped since the last time, bringing the cost down to a level where I
-guess even small organizations can afford to store the audio recording
-from every phone call taken in a year in Norway.  Of course, this is
-just the cost of buying the storage equipment.  Maintenance, need to
-be included as well, but the volume of a single year is about a single
-rack of hard drives, so it is not much more than I could fit in my own
-home.  Wonder how much the electricity bill would raise if I had that
-kind of storage?  I doubt it would be more than a few tens of thousand
-NOK per year.&lt;/p&gt;
