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.

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> + + + + + Jami as a Zoom client, a trick for password protected rooms... + http://people.skolelinux.org/pere/blog/Jami_as_a_Zoom_client__a_trick_for_password_protected_rooms___.html + http://people.skolelinux.org/pere/blog/Jami_as_a_Zoom_client__a_trick_for_password_protected_rooms___.html + Fri, 8 May 2020 13:30:00 +0200 + <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> + +<p>As usual, if you use Bitcoin and want to show your support of my +activities, please send Bitcoin donations to my address +<b><a href="bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a></b>.</p> + + + + + GnuCOBOL, a free platform to learn and use COBOL - nice free software + http://people.skolelinux.org/pere/blog/GnuCOBOL__a_free_platform_to_learn_and_use_COBOL___nice_free_software.html + http://people.skolelinux.org/pere/blog/GnuCOBOL__a_free_platform_to_learn_and_use_COBOL___nice_free_software.html + Wed, 29 Apr 2020 13:10:00 +0200 + <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 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> - - -
