+ <description><p>Det er tett med sensorstasjoner langs veinettet i Norge, som
+registrerer hvilke kjøretøy som passerer eller tar bilde av de som
+drar forbi. I følge
+<a href="https://vegkart.atlas.vegvesen.no/">Vegvesenets nasjonale
+veidatabank (NVDB)</a>, er det 353 bomstasjoner langs det norske
+veinettet. 21 i nordnorge, 48 i trøndelagsområdet, 13 på
+nordvestlandet, 91 i bergenstraktene og 180 på østlandsområdet. I
+tillegg finnes det et utall overvåkningskamera og noen titalls
+RFID-avlesere for bompengebrikker som samler inn informasjon om hvilke
+biler som befinner seg hvor i landet. For ikke å glemme alle
+mobilbasestasjoner som registrerer hvor brukere av mobilnettverket
+befinner seg. De er ikke tema i dag.</p>
+
+<p>De som kjører mye har interesse av å vite hvor mye bompenger det vil
+koste å kjøre fra et sted til et annet, og dette behovet har aktørene
+bak <a href="https://bompengekalkulator.no/">Bompengekalkulatoren</a>
+tatt sikte på å tilby i markedet. Fornuftig nok har de også en
+gratistjeneste, slik at de får frivillige til å gi innspill om feil i
+datagrunnlaget. Jeg ble nylig nysgjerring på hvor mye det til koste å
+kjøre på kryss og tvers i Norge, og valgte meg ut en teststrekning fra
+Oslo til Tromsø for å se hvilke beløp som gjelder.</p>
+
+<p>Bompengekalkulatoren viser frem flere rutealternativer for et gitt
+reisesøk, og i dette tilfellet, for reise fra Oslo Sentralstasjon til
+Tromsø sentrum, viser den tre alternativ. Merk, disse tallene gjelder
+bensindrevet personbil. En kan velge takstkategori i
+webgrensesnittet. Det ene rutealternativet er E6 gjennom Norge, de to
+andre er E45 og E4 gjennom sverige. E45 er innlandsruten i Sverige,
+motorvei gjennom store skoger som i følge kalkulatoren skal ta 22
+timer og 26 minutter med norsk bompengebeløp på 164 kroner. Jeg har
+mine tvil til om datasettet til Bompengekalkulatoren har svenske
+bomstasjoner, så ta dette beløpet med en klype salt. E4 er veien
+langs Bottenviken og mer befolket område, og skal ta 22 timer og 50
+minutter til en norsk bompengebeløp på 71 kroner. Den norske ruten
+langs E6 skal derimot ta 23 timer og 16 minutter og beløpe seg til 664
+kroner. Beløpene er uten autopass-brikke, slik at en slipper å få
+bilens posisjon registrert i alle bompengeavleserne som ikke også er
+bomstasjoner. For trailere er bompengekostnaden 2-3 ganger så høy som
+for personbil. I tillegg til pengebeløpet, som faktureres
+etterskuddsvis og de siste årene har blitt umulig å gjøre opp kontant
+på stedet, så kommer kostnaden med å få sine personopplysninger samlet
+inn, lagret og gjort tilgjengelig for fremmede på ubestemt tid. Jeg
+ser på den kostnaden som mye høyere en pengebeløpet som
+faktureres.</p>
+
+<p>For en tilsvarende tur fra Oslo til Bergen, så forteller
+kalkulatoren at raskeste vei er riksvei 7 på 7 timer 4 minutter med
+bompengebeløp 409 kroner. Alternativene listet opp er E134 på 8 timer
+37 minutter med bompengebeløp 318 kroner og fylkesivei 40 på 7 timer
+30 minutter med beløp 331. Det kan kanskje være greit å sjekke ut før
+en setter seg i bilen hvor ens personopplysninger vil bli samlet inn
+og lagret 5 fem år, når en velger hvilken rute en går for.</p>

+ <description><p>I am very happy to report that a more reliable
+<a href="https://tracker.debian.org/pkg/vlc-plugin-bittorrent">VLC
+bittorrent plugin</a> was just uploaded into debian. This fixes a
+couple of crash bugs in the plugin, hopefully making the VLC
+experience even better when streaming directly from a bittorrent
+source. The package is currently in Debian unstable, but should be
+available in Debian testing in two days. To test it, simply install
+it like this:</p>
+
+<p><pre>
+apt install vlc-plugin-bittorrent
+</pre></p>
+
+<p>After it is installed, you can try to use it to play a file
+downloaded live via bittorrent like this:
+
+<p><pre>
+vlc https://archive.org/download/Glass_201703/Glass_201703_archive.torrent
+</pre></p>
+
+<p>It also support magnet links and local .torrent files.</p>

+ <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Yvan_Masson.html</guid>
+ <pubDate>Tue, 12 May 2020 06:30:00 +0200</pubDate>
+ <description><p>It has been way too long since my last interview, but as the
+<a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>
+community is still active, and new people keep showing up on the IRC
+channel <a href="irc://irc.debian.org/#debian-edu">#debian-edu</a> and
+<a href="https://lists.debian.org/debian-edu/">the debian-edu mailing
+list</a>, I decided to give it another go. I was hoping someone else
+might pick up the idea and run with it, but this has not happened as
+far as I can tell, so here we are… This time the announcement of a new
+free software tool to
+<a href="https://framagit.org/Yvan-Masson/WhosWho">create a school year
+book</a> triggered my interest, and I decided to learn more about its
+author.</p>
+
+<p><strong>Who are you, and how do you spend your days?</strong></p>
+
+<p>My name is Yvan MASSON, I live in France. I have my own one person
+business in computer services. The work consist of visiting my
+customers (person's home, local authority, small business) to give
+advise, install computers and software, fix issues, and provide
+computing usage training. I spend the rest of my time enjoying my
+family and promoting free software.</p>
+
+<p><strong>What is your approach for promoting free
+software?</strong></p>
+
+<p>When I think that free software could be suitable for someone, I
+explain what it is, with simple words, give a few known examples, and
+explain that while there is no fee it is a viable alternative in many
+situations. Most people are receptive when you explain how it is
+better (I simplify arguments here, I know that it is not so simple):
+Linux works on older hardware, there are no viruses, and the software
+can be audited to ensure user is not spied upon. I think the most
+important is to keep a clear but moderated speech: when you try to
+convince too much, people feel attacked and stop listening.</p>
+
+<p><strong>How did you get in contact with the Skolelinux / Debian Edu
+project?</strong></p>
+
+<p>I can not remember how I first heard of Skolelinux / Debian Edu,
+but probably on planet.debian.org. As I have been working for a
+school, I have interest in this type of project.
+
+<p>The school I am involved in is a school for "children" between 14
+and 18 years old. The French government has recommended free software
+since 2012, but they do not always use free software themselves. The
+school computers are still using the Windows operating system, but all
+of them have the classic set of free software: Firefox ESR,
+LibreOffice (with the excellent extension Grammalecte that indicates
+French grammatical errors), SumatraPDF, Audacity, 7zip, KeePass2, VLC,
+GIMP, Inkscape…
+
+<p><strong>What do you see as the advantages of Skolelinux / Debian
+Edu?</strong></p>
+
+<p>It is free software! Built on Debian, I am sure that users are not
+spied upon, and that it can run on low end hardware. This last point
+is very important, because we really need to improve "green IT". I do
+not know enough about Skolelinux / Debian Edu to tell how it is better
+than another free software solution, but what I like is the "all in
+one" solution: everything has been thought of and prepared to ease
+installation and usage.</p>
+
+<p>I like Free Software because I hate using something that I can not
+understand. I do not say that I can understand everything nor that I
+want to understand everything, but knowing that someone / some company
+intentionally prevents me from understanding how things work is really
+unacceptable to me.</p>
+
+<p>Secondly, and more importantly, free software is a requirement to
+prevent abuses regarding human rights and environmental care.
+Humanity can not rely on tools that are in the hands of small group of
+people.</p>
+
+<p><strong>What do you see as the disadvantages of Skolelinux / Debian
+Edu?</strong></p>
+
+<p>Again, I don't know this project enough. Maybe a dedicated website?
+Debian wiki works well for documentation, but is not very appealing to
+someone discovering the project. Also, as Skolelinux / Debian Edu uses
+OpenLDAP, it probably means that Windows workstations cannot use
+centralized authentication. Maybe the project could use Samba as an
+Active Directory domain controller instead, allowing Windows desktop
+usage when necessary.</p>
+
+<p>(Editors note: In fact Windows workstations can
+<a href="https://wiki.debian.org/DebianEdu/Documentation/Buster/HowTo/Samba">use
+the centralized authentication in a Debian Edu setup</a>, at least for
+some versions of Windows, but the fact that this is not well known can
+be seen as an indication of the need for better documentation and
+marketing. :)</p>
+
+<p><strong>Which free software do you use daily?</strong></p>
+
+<p>Nothing original: Debian testing/sid with Gnome desktop, Firefox,
+Thunderbird, LibreOffice…</p>
+
+<p><strong>Which strategy do you believe is the right one to use to
+get schools to use free software?</strong></p>
+
+<p>Every effort to spread free software into schools is important,
+whatever it is. But I think, at least where I live, that IT
+professionals maintaining schools networks are still very "Microsoft
+centric". Schools will use any working solution, but they need people
+to install and maintain it. How to make these professionals sensitive
+about free software and train them with solutions like Debian Edu /
+Skolelinux is a really good question :-)</p>

+ <title>Jami as a Zoom client, a trick for password protected rooms...</title>

+ <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Jami_as_a_Zoom_client__a_trick_for_password_protected_rooms___.html</guid>
+ <pubDate>Fri, 8 May 2020 13:30:00 +0200</pubDate>
+ <description><p>Half a year ago,
+<a href="http://people.skolelinux.org/pere/blog/Jami_Ring__finally_functioning_peer_to_peer_communication_client.html">I
+wrote</a> about <a href="https://jami.net/">the Jami communication
+client</a>, capable of peer-to-peer encrypted communication. It
+handle both messages, audio and video. It uses distributed hash
+tables instead of central infrastructure to connect its users to each
+other, which in my book is a plus. I mentioned briefly that it could
+also work as a SIP client, which came in handy when the higher
+educational sector in Norway started to promote Zoom as its video
+conferencing solution. I am reluctant to use the official Zoom client
+software, due to their <a href="https://zoom.us/terms">copyright
+license clauses</a> prohibiting users to reverse engineer (for example
+to check the security) and benchmark it, and thus prefer to connect to
+Zoom meetings with free software clients.</p>
+
+<p>Jami worked OK as a SIP client to Zoom as long as there was no
+password set on the room. The Jami daemon leak memory like crazy
+(approximately 1 GiB a minute) when I am connected to the video
+conference, so I had to restart the client every 7-10 minutes, which
+is not a great. I tried to get other SIP Linux clients to work
+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
+could not get my dial tone signaling through from Jami to Zoom, and
+dial tone signaling is used to enter the password when connecting to
+Zoom. I tried a lot of different permutations with my Jami and
+Asterisk setup to try to figure out why the signaling did not get
+through, only to finally discover that the fundamental problem seem to
+be that Zoom is simply not able to receive dial tone signaling when
+connecting via SIP. There seem to be nothing wrong with the Jami and
+Asterisk end, it is simply broken in the Zoom end. I got help from a
+very skilled VoIP engineer figuring out this last part. And being a
+very skilled engineer, he was also able to locate a solution for me.
+Or to be exact, a workaround that solve my initial problem of
+connecting to password protected Zoom rooms using Jami.</p>
+
+<p>So, how do you do this, I am sure you are wondering by now. The
+trick is already
+<a href="https://support.zoom.us/hc/en-us/articles/202405539-H-323-SIP-Room-Connector-Dial-Strings#sip">documented
+from Zoom</a>, and it is to modify the SIP address to include the room
+password. What is most surprising about this is that the
+automatically generated email from Zoom with instructions on how to
+connect via SIP do not mention this. The SIP address to use normally
+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
+ID].[Password].[Layout].[Host Key]</tt>", and you can hear see how you
+can both enter password, control the layout (full screen, active
+presence and gallery) and specify the host key to start the meeting.
+The full SIP address entered into Jami to provide the password will
+then look like this (all using made up numbers):</p>
+
+<p><blockquote>
+<tt>sip:657837644.522827@192.168.169.170</tt>
+</blockquote></p>
+
+<p>Now if only jami would reduce its memory usage, I could even
+recommend this setup to others. :)</p>

+ <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>

-hos
-<a href="https://no.quora.com/Hva-er-din-favoritthistorie">Quora</a>.
-Fant også <a href="https://www.youtube.com/watch?v=-qClChUdlfI">en
-filmatisering</a>, men den versjonen jeg liker best fant jeg
-<a href="https://www.goodreads.com/author/quotes/56782.Loren_Eiseley">hos
-Goodreads</a>. Jeg oversatte den utgaven til norsk i går, og har lyst
-til å dele den med deg:
-
-<blockquote><p>Mens jeg tok en pause fra skrivingen og vandret på en
-øde strand ved daggry, så jeg en gutt i det fjerne bøye seg ned og
-kaste noe mens han vandret mot meg over den endeløse stranden. Da han
-kom nærmere, kunne jeg se at han kastet sjøstjerner, som var etterlatt
-i sanden av tidevannet, tilbake i havet. Da han var nær nok spurte jeg
-ham hvorfor han jobbet så hardt på denne merkelige oppgaven. Han sa at
-solen snart ville stå opp og tørke sjøstjernene slik at de ville
-dø.</p>
-
-<p>Jeg sa til ham at dette var helt meningsløst. Det var kilometer på
-kilometer med strand, og det lå sjøstjerner hele veien. En person
-alene kunne ikke gjøre noen forskjell. Han smilte da han plukket opp
-neste sjøstjerne. Mens han kastet den så langt ut i havet som han
-klarte sa han, «for denne gjør det en forskjell». Jeg droppet
-skrivingen og tilbrakte resten av morgenen med å kaste
-sjøstjerner.</p>

- <description><p>When asked to accept terms of use and privacy policies that state
-it will to remove rights I otherwise had or accept unreasonable terms
-undermining my privacy, I choose away the service. I simply do not
-have the conscience to accept terms I have no indention of upholding.
-But how are the system and service providers to know how many people
-they scared away? Normally I just quietly walk away. But today, I
-tried a new approach. I sent the following email (removing the
-specifics, as I am not out to take the specific service in question)
-to the service provider I decided to not use, to at least give them
-one data point on how many users are unhappy with their terms:</p>

-<p>Dear [Site Owner],</p>
-
-<p>I was eager to test the system, as it seemed like a fun and
-interesting application of [some] technology, but after reading the
-terms of use and privacy policy on &lt;URL:
-https://www.[some.site]/terms-of-use &gt; and &lt;URL:
-https://www.[some.site]/privacy-policy &gt; I want you to know that I
-decided to turn away. There were several provisions in the terms and
-policy turning me off, but the final term that convinced me was being
-asked to sign away my right to reverse engineer.</p>
-
-<p>--
-<br>Happy hacking
-<br>Petter Reinholdtsen</p>
-</blockquote>
-
-<p>I do not expect much to come out of it, but sharing it here in case
-others want to give something similar a try too. If companies
-discover their terms scare away enough people, perhaps they will be
-improved...</p>

- <title>What would it cost to store all 2018 phone calls in Norway?</title>

- <description><p>Four years ago, I did a back of the envelope calculation on
-<a href="http://people.skolelinux.org/pere/blog/What_would_it_cost_to_store_all_phone_calls_in_Norway_.html">how
-much it would cost to store audio recordings of all the phone calls in
-Norway</a>, 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.</p>
-
-<p>The number of phone call minutes for 2018 was fetched from
-<a href="https://ekomstatistikken.nkom.no/">the NKOM statistics
-site</a>, 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.</p>
-
-<p>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.</p>
-
-<p>So, with the parameters in place, lets update the old table
-estimating cost for calls in a given year:</p>
-
-<table border="1">
-<tr><th>Year</th><th>Call minutes</th><th>Size</th><th>Price in NOK / EUR</th></tr>
-<tr><td>2005</td><td align="right">24 000 000 000</td><td align="right">1.3 PiB</td><td align="right">1 170 000 / 117 000</td></tr>
-
-<tr><td>2012</td><td align="right">18 000 000 000</td><td align="right">1.0 PiB</td><td align="right">900 000 / 90 000</td></tr>
-
-<tr><td>2013</td><td align="right">17 000 000 000</td><td align="right">950 TiB</td><td align="right">855 000 / 85 500</td></tr>
-
-<tr><td>2018</td><td align="right">7 976 244 000</td><td align="right">445 TiB</td><td align="right">401 100 / 40 110</td></tr>
-</table>
-
-<p>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.</p>
