+ <div class="body"><p>The movie "<a href="http://www.takepart.com/internets-own-boy">The
+Internet's Own Boy: The Story of Aaron Swartz</a>" is both inspiring
+and depressing at the same time. The work of Aaron Swartz has
+inspired me in my work, and I am grateful of all the improvements he
+was able to initiate or complete. I wish I am able to do as much good
+in my life as he did in his. Every minute of this 1:45 long movie is
+inspiring in documenting how much impact a single person can have on
+improving the society and this world. And it is depressing in
+documenting how the law enforcement of USA (and other countries) is
+corrupted to a point where they can push a bright kid to his death for
+downloading too many scientific articles. Aron is dead. Let us all
+weep.</p>
+
+<p>The movie is also available on
+<a href="https://www.youtube.com/watch?v=vXr-2hwTk58">Youtube</a>. I
+wish there were Norwegian subtitles available, so I could show it to
+my parents.</p>

+ <div class="date"> 7th October 2015</div>
+ <div class="body"><p>Jeg lot meg fascinere av
+<a href="http://www.aftenposten.no/nyheter/iriks/politikk/Stortinget-har-tilgang-til-a-fjernstyre-600-mobiler-8192692.html">en
+artikkel i Aftenposten</a> der det fortelles at «over 600 telefoner som
+benyttes av stortingsrepresentanter, rådgivere og ansatte på
+Stortinget, kan «fjernstyres» ved hjelp av
+<a href="https://play.google.com/store/apps/details?id=com.airwatch.androidagent">programvaren
+Airwatch</a>, et såkalte MDM-program (Mobile Device Managment)». Det
+hele bagatelliseres av Stortingets IT-stab, men det er i hovedsak på
+grunn av at journalisten ikke stiller de relevante spørsmålene. For
+meg er det relevante spørsmålet hvem som har lovlig tilgang (i henhold
+til lokal lovgiving, dvs. i hvert fall i Norge, Sverige, UK og USA)
+til informasjon om og på telefonene, og hvor enkelt det er å skaffe
+seg tilgang til hvor mobilene befinner seg og informasjon som befinner
+seg på telefonene ved hjelp av utro tjenere, trusler, innbrudd og
+andre ulovlige metoder.</p>
+
+<p>Bruken av AirWatch betyr i realiteten at USAs etteretning og
+politimyndigheter har full tilgang til stortingets mobiltelefoner,
+inkludert posisjon og innhold, takket være
+<a href="https://en.wikipedia.org/wiki/Foreign_Intelligence_Surveillance_Act_of_1978_Amendments_Act_of_2008">FISAAA-loven</a>
+og
+"<a href="https://en.wikipedia.org/wiki/National_security_letter">National
+Security Letters</a>" og det enkle faktum at selskapet
+<a href="http://www.airwatch.com/">AirWatch</a> er kontrollert av et
+selskap i USA. I tillegg er det kjent at flere lands
+etterretningstjenester kan lytte på trafikken når den passerer
+landegrensene.</p>
+
+<p>Jeg har bedt om mer informasjon
+<a href="https://www.mimesbronn.no/request/saksnummer_for_saker_anganede_br">fra
+Stortinget om bruken av AirWatch</a> via Mimes brønn så får vi se hva
+de har å fortelle om saken. Fant ingenting om 'airwatch' i
+postjournalen til Stortinget, så jeg trenger hjelp før jeg kan be om
+innsyn i konkrete dokumenter.</p>
+
+<p>Oppdatering 2015-10-07: Jeg er blitt spurt hvorfor jeg antar at
+AirWatch-agenten rapporterer til USA og ikke direkte til Stortingets
+egen infrastruktur. Det stemmer at det er teknisk mulig å sette
+opp mobiltelefonene til å rapportere til datamaskiner som eies av
+Stortinget. Jeg antar det rapporteres til AirWatch sine sentrale
+tjenester basert på det jeg leste fra beskrivelsen av
+<a href="http://www.airwatch.com/solutions/mobile-device-management/">Mobile
+Device Management</A> på AirWatch sine egne nettsider, koblet med at
+det brukes en standard app som kan hentes fra "app-butikkene" for å få
+tilgang. Enten må app-en settes opp individuelt hos Stortinget, eller
+så får den beskjed fra AirWatch i USA om hvor den skal koble seg opp.
+I det første tilfellet vil den ikke rapportere direkte til USA, men
+til programvare utviklet av AirWatch som kjører på en maskin under
+Stortingets kontroll. Det er litt bedre, men fortsatt vil det være
+umulig for Stortinget å være sikker på hva programvaren som tar imot
+forbindelser gjør. Jeg ser fra beskrivelsen av
+<a href="http://www.airwatch.com/differentiators/enterprise-integration/">Enterprice
+Integration</a> hos AirWatch at det er mulig å ha lokal installasjon,
+og håper innsynsforespørsler mot Stortinget kan fortelle mer om
+hvordan ting konkret fungerer der.</p>

+ <div class="body"><p>As I wrap up the Norwegian version of
+<a href="https://github.com/petterreinholdtsen/free-culture-lessig">Free
+Culture</a> book by Lawrence Lessig (still waiting for my final proof
+reading copy to arrive in the mail), my great
+<a href="http://dblatex.sourceforge.net/">dblatex</a> helper and
+developer of the dblatex docbook processor, Benoît Guillon, decided a
+to try to create a French version of the book. He started with the
+French translation available from the

+pages</a>, and wrote a program to convert it into a PO file, allowing
+the translation to be integrated into the po4a based framework I use
+to create the Norwegian translation from the English edition. We meet
+on the <a href="irc://irc.freenode.net/%23dblatex">#dblatex IRC
+channel</a> to discuss the work. If you want to help create a French
+edition, check out
+<a href="https://github.com/marsgui/free-culture-lessig">his git
+repository</a> and join us on IRC. If the French edition look good,
+we might publish it as a paper book on lulu.com. A French version of
+the drawings and the cover need to be provided for this to happen.</p>

+ <div class="date">24th September 2015</div>
+ <div class="body"><p>When I get a new laptop, the battery life time at the start is OK.
+But this do not last. The last few laptops gave me a feeling that
+within a year, the life time is just a fraction of what it used to be,
+and it slowly become painful to use the laptop without power connected
+all the time. Because of this, when I got a new Thinkpad X230 laptop
+about two years ago, I decided to monitor its battery state to have
+more hard facts when the battery started to fail.</p>
+
+<img src="http://people.skolelinux.org/pere/blog/images/2015-09-24-laptop-battery-graph.png"/>
+
+<p>First I tried to find a sensible Debian package to record the
+battery status, assuming that this must be a problem already handled
+by someone else. I found
+<a href="https://tracker.debian.org/pkg/battery-stats">battery-stats</a>,
+which collects statistics from the battery, but it was completely
+broken. I sent a few suggestions to the maintainer, but decided to
+write my own collector as a shell script while I waited for feedback
+from him. Via
+<a href="http://www.ifweassume.com/2013/08/the-de-evolution-of-my-laptop-battery.html">a
+blog post about the battery development on a MacBook Air</a> I also
+discovered
+<a href="https://github.com/jradavenport/batlog.git">batlog</a>, not
+available in Debian.</p>
+
+<p>I started my collector 2013-07-15, and it has been collecting
+battery stats ever since. Now my
+/var/log/hjemmenett-battery-status.log file contain around 115,000
+measurements, from the time the battery was working great until now,
+when it is unable to charge above 7% of original capacity. My
+collector shell script is quite simple and look like this:</p>
+
+<pre>
+#!/bin/sh
+# Inspired by
+# http://www.ifweassume.com/2013/08/the-de-evolution-of-my-laptop-battery.html
+# See also
+# http://blog.sleeplessbeastie.eu/2013/01/02/debian-how-to-monitor-battery-capacity/
+logfile=/var/log/hjemmenett-battery-status.log
+
+files="manufacturer model_name technology serial_number \
+ energy_full energy_full_design energy_now cycle_count status"
+
+if [ ! -e "$logfile" ] ; then
+ (
+ printf "timestamp,"
+ for f in $files; do
+ printf "%s," $f
+ done
+ echo
+ ) > "$logfile"
+fi
+
+log_battery() {
+ # Print complete message in one echo call, to avoid race condition
+ # when several log processes run in parallel.
+ msg=$(printf "%s," $(date +%s); \
+ for f in $files; do \
+ printf "%s," $(cat $f); \
+ done)
+ echo "$msg"
+}
+
+cd /sys/class/power_supply
+
+for bat in BAT*; do
+ (cd $bat && log_battery >> "$logfile")
+done
+</pre>
+
+<p>The script is called when the power management system detect a
+change in the power status (power plug in or out), and when going into
+and out of hibernation and suspend. In addition, it collect a value
+every 10 minutes. This make it possible for me know when the battery
+is discharging, charging and how the maximum charge change over time.
+The code for the Debian package
+<a href="https://github.com/petterreinholdtsen/battery-status">is now
+available on github</a>.</p>
+
+<p>The collected log file look like this:</p>
+
+<pre>
+timestamp,manufacturer,model_name,technology,serial_number,energy_full,energy_full_design,energy_now,cycle_count,status,
+1376591133,LGC,45N1025,Li-ion,974,62800000,62160000,39050000,0,Discharging,
+[...]

+</pre>
+
+<p>I wrote a small script to create a graph of the charge development
+over time. This graph depicted above show the slow death of my laptop
+battery.</p>
+
+<p>But why is this happening? Why are my laptop batteries always
+dying in a year or two, while the batteries of space probes and
+satellites keep working year after year. If we are to believe
+<a href="http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries">Battery
+University</a>, the cause is me charging the battery whenever I have a
+chance, and the fix is to not charge the Lithium-ion batteries to 100%
+all the time, but to stay below 90% of full charge most of the time.
+I've been told that the Tesla electric cars
+<a href="http://my.teslamotors.com/de_CH/forum/forums/battery-charge-limit">limit
+the charge of their batteries to 80%</a>, with the option to charge to
+100% when preparing for a longer trip (not that I would want a car
+like Tesla where rights to privacy is abandoned, but that is another
+story), which I guess is the option we should have for laptops on
+Linux too.</p>
+
+<p>Is there a good and generic way with Linux to tell the battery to
+stop charging at 80%, unless requested to charge to 100% once in
+preparation for a longer trip? I found
+<a href="http://askubuntu.com/questions/34452/how-can-i-limit-battery-charging-to-80-capacity">one
+recipe on askubuntu for Ubuntu to limit charging on Thinkpad to
+80%</a>, but could not get it to work (kernel module refused to
+load).</p>
+
+<p>I wonder why the battery capacity was reported to be more than 100%
+at the start. I also wonder why the "full capacity" increases some
+times, and if it is possible to repeat the process to get the battery
+back to design capacity. And I wonder if the discharge and charge
+speed change over time, or if this stay the same. I did not yet try
+to write a tool to calculate the derivative values of the battery
+level, but suspect some interesting insights might be learned from
+those.</p>
+
+<p>Update 2015-09-24: I got a tip to install the packages
+acpi-call-dkms and tlp (unfortunately missing in Debian stable)
+packages instead of the tp-smapi-dkms package I had tried to use
+initially, and use 'tlp setcharge 40 80' to change when charging start
+and stop. I've done so now, but expect my existing battery is toast
+and need to be replaced. The proposal is unfortunately Thinkpad
+specific.</p>

+ <div class="date"> 3rd September 2015</div>
+ <div class="body"><p>Creating a good looking book cover proved harder than I expected.
+I wanted to create a cover looking similar to the original cover of
+the
+<a href="https://github.com/petterreinholdtsen/free-culture-lessig">Free
+Culture</a> book we are translating to Norwegian, and I wanted it in
+vector format for high resolution printing. But my inkscape knowledge
+were not nearly good enough to pull that off.
+
+<p>But thanks to the great inkscape community, I was able to wrap up
+the cover yesterday evening. I asked on the
+<a href="irc://irc.freenode.net/%23inkscape">#inkscape IRC channel</a>
+on Freenode for help and clues, and Marc Jeanmougin (Mc-) volunteered
+to try to recreate it based on the PDF of the cover from the HTML
+version. Not only did he create a
+<a href="https://marc.jeanmougin.fr/share/copy1.svg ">SVG document with
+the original and his vector version side by side</a>, he even provided
+an <a href="https://marc.jeanmougin.fr/share/out-1.ogv">instruction
+video</a> explaining how he did it</a>. But the instruction video is
+not easy to follow for an untrained inkscape user. The video is a
+recording on how he did it, and he is obviously very experienced as
+the menu selections are very quick and he mentioned on IRC that he did
+use some keyboard shortcuts that can't be seen on the video, but it
+give a good idea about the inkscape operations to use to create the
+stripes with the embossed copyright sign in the center.</p>
+
+<p>I took his SVG file, copied the vector image and re-sized it to fit
+on the cover I was drawing. I am happy with the end result, and the
+current english version look like this:</p>
+
+<img src="http://people.skolelinux.org/pere/blog/images/2015-09-03-free-culture-cover.png" width="70%" align="center"/>
+
+<p>I am not quite sure about the text on the back, but guess it will
+do. I picked three quotes from the official site for the book, and
+hope it will work to trigger the interest of potential readers. The
+Norwegian cover will look the same, but with the texts and bar code
+replaced with the Norwegian version.</p>
+
+<p>The book is very close to being ready for publication, and I expect
+to upload the final draft to Lulu in the next few days and order a
+final proof reading copy to verify that everything look like it should
+before allowing everyone to order their own copy of Free Culture, in
+English or Norwegian Bokmål. I'm waiting to give the the productive
+proof readers a chance to complete their work.</p>

+ <div class="date">19th August 2015</div>
+ <div class="body"><p>Today, finally, my first printed draft edition of the Norwegian
+translation of Free Culture I have been working on for the last few
+years arrived in the mail. I had to fake a cover to get the interior
+printed, and the exterior of the book look awful, but that is
+irrelevant at this point. I asked for a printed pocket book version
+to get an idea about the font sizes and paper format as well as how
+good the figures and images look in print, but also to test what the
+pocket book version would look like. After receiving the 500 page
+pocket book, it became obvious to me that that pocket book size is too
+small for this book. I believe the book is too thick, and several
+tables and figures do not look good in the size they get with that
+small page sizes. I believe I will go with the 5.5x8.5 inch size
+instead. A surprise discovery from the paper version was how bad the
+URLs look in print. They are very hard to read in the colophon page.
+The URLs are red in the PDF, but light gray on paper. I need to
+change the color of links somehow to look better. But there is a
+printed book in my hand, and it feels great. :)</p>
+
+<p>Now I only need to fix the cover, wrap up the postscript with the
+store behind the book, and collect the last corrections from the proof
+readers before the book is ready for proper printing. Cover artists
+willing to work for free and create a Creative Commons licensed vector
+file looking similar to the original is most welcome, as my skills as
+a graphics designer are mostly missing.</p>

- <div class="date"> 5th July 2015</div>
- <div class="body"><p>Several people contacted me after my previous blog post about my
-need for a new laptop, and provided very useful feedback. I wish to
-thank every one of these. Several pointed me to the possibility of
-fixing my X230, and I am already in the process of getting Lenovo to
-do so thanks to the on site, next day support contract covering the
-machine. But the battery is almost useless (I expect to replace it
-with a non-official battery) and I do not expect the machine to live
-for many more years, so it is time to plan its replacement. If I did
-not have a support contract, it was suggested to find replacement parts
-using <a href="http://www.francecrans.com/">FrancEcrans</a>, but it
-might present a language barrier as I do not understand French.</p>
-
-<p>One tip I got was to use the
-<a href="https://skinflint.co.uk/?cat=nb">Skinflint</a> web service to
-compare laptop models. It seem to have more models available than
-prisjakt.no. Another tip I got from someone I know have similar
-keyboard preferences was that the HP EliteBook 840 keyboard is not
-very good, and this matches my experience with earlier EliteBook
-keyboards I tested. Because of this, I will not consider it any further.
-
-<p>When I wrote my blog post, I was not aware of Thinkpad X250, the
-newest Thinkpad X model. The keyboard reintroduces mouse buttons
-(which is missing from the X240), and is working fairly well with
-Debian Sid/Unstable according to
-<a href="http://www.corsac.net/X250/">Corsac.net</a>. The reports I
-got on the keyboard quality are not consistent. Some say the keyboard
-is good, others say it is ok, while others say it is not very good.
-Those with experience from X41 and and X60 agree that the X250
-keyboard is not as good as those trusty old laptops, and suggest I
-keep and fix my X230 instead of upgrading, or get a used X230 to
-replace it. I'm also told that the X250 lack leds for caps lock, disk
-activity and battery status, which is very convenient on my X230. I'm
-also told that the CPU fan is running very often, making it a bit
-noisy. In any case, the X250 do not work out of the box with Debian
-Stable/Jessie, one of my requirements.</p>
-
-<p>I have also gotten a few vendor proposals, one was
-<a href="http://pro-star.com">Pro-Star</a>, another was
-<a href="http://shop.gluglug.org.uk/product/libreboot-x200/">Libreboot</a>.
-The latter look very attractive to me.</p>
-
-<p>Again, thank you all for the very useful feedback. It help a lot
-as I keep looking for a replacement.</p>
-
-<p>Update 2015-07-06: I was recommended to check out the
-<a href="">lapstore.de</a> web shop for used laptops. They got several
-different
-<a href="http://www.lapstore.de/f.php/shop/lapstore/f/411/lang/x/kw/Lenovo_ThinkPad_X_Serie/">old
-thinkpad X models</a>, and provide one year warranty.</p>

- <div class="body"><p>My primary work horse laptop is failing, and will need a
-replacement soon. The left 5 cm of the screen on my Thinkpad X230
-started flickering yesterday, and I suspect the cause is a broken
-cable, as changing the angle of the screen some times get rid of the
-flickering.</p>
-
-<p>My requirements have not really changed since I bought it, and is
-still as
-<a href="http://people.skolelinux.org/pere/blog/Thank_you_Thinkpad_X41__for_your_long_and_trustworthy_service.html">I
-described them in 2013</a>. The last time I bought a laptop, I had
-good help from
-<a href="http://www.prisjakt.no/category.php?k=353">prisjakt.no</a>
-where I could select at least a few of the requirements (mouse pin,
-wifi, weight) and go through the rest manually. Three button mouse
-and a good keyboard is not available as an option, and all the three
-laptop models proposed today (Thinkpad X240, HP EliteBook 820 G1 and
-G2) lack three mouse buttons). It is also unclear to me how good the
-keyboard on the HP EliteBooks are. I hope Lenovo have not messed up
-the keyboard, even if the quality and robustness in the X series have
-deteriorated since X41.</p>
-
-<p>I wonder how I can find a sensible laptop when none of the options
-seem sensible to me? Are there better services around to search the
-set of available laptops for features? Please send me an email if you

- <div class="body"><p>Last oktober I was involved on behalf of
-<a href="http://www.nuug.no/">NUUG</a> with recording the talks at
-<a href="http://www.makercon.no/">MakerCon Nordic</a>, a conference for
-the Maker movement. Since then it has been the plan to publish the
-recordings on <a href="http://www.frikanalen.no/">Frikanalen</a>, which
-finally happened the last few days. A few talks are missing because
-the speakers asked the organizers to not publish them, but most of the
-talks are available. The talks are being broadcasted on RiksTV
-channel 50 and using multicast on Uninett, as well as being available
-from the Frikanalen web site. The unedited recordings are
-<a href="https://www.youtube.com/user/MakerConNordic/">available on
-Youtube too</a>.</p>
-
-<p>This is the list of talks available at the moment. Visit the

- <div class="date">28th June 2015</div>
- <div class="body"><p>I en global verden med eierskap på tvers, trengs det informasjon om
-hvem som har kontrollen i selskaper og bedrifter. Og for å få tilgang
-til slik informasjon for alle som ønsker å analysere eierskap, holder
-med ikke med nasjonale databaser over eierskap, det må globale
-samledatabaser med åpne data til. Heldigvis finnes det en
-internasjonal bevegelse for å gjøre selskapsinformasjon for alle land
-offentlig tilgjengelig. En slik database heter
-<a href="http://opencorporates.com">OpenCorporates</a>, der
-informasjonen er gratis tilgjengelig med en "del på samme
-vilkår"-lisens. De samler inn selskapsinformasjon, eierskap,
-konsesjonstildelinger og lignende. De manglet ganske mye for Norge,
-da bruksvilkårene til Norsk offentlig informasjon i stor grad
-blokkerer OpenCorporates fra å samle den inn.</p>
-
-<p>Men jeg er jo involvert i
-<a href="http://www.frikanalen.no/">Frikanalen</a>, som har
-TV-konsesjon, og tenkte det kunne være fint om informasjon om alle
-mediakonsesjoner var tilgjengelig i OpenCorporates, så jeg sendte
-avgårde følgende spørsmål til Medietilsynet 2015-06-22:</p>
-
-<blockquote>
-<p>Hei. Finnes det en oversikt over enhetene som Mediatilsynet fører
-tilsyn med som åpne data? Jeg lette etter den på
-<URL:<a href="http://data.norge.no/">http://data.norge.no/</a>> og
-<URL:<a href="http://hotell.difi.no/">http://hotell.difi.no/</a>> uten å
-finne noe der, og fant heller ikke noe under
-<URL:<a href="http://www.medietilsynet.no/">http://www.medietilsynet.no/</a>>.</p>
-
-<p>Jeg tenker på alle som har fått kringkastingskonsesjon og alle som
-er omtalt under
-<URL:<a href="http://www.medietilsynet.no/mediebildet/">http://www.medietilsynet.no/mediebildet/</a>>.</p>
-
-<p>Jeg skulle gjerne hatt dette maskinlesbart, og inkludert
-organisasjonsnummer og hva slags forhold mediatilsynet har til
-organisasjonene. Tanken er å importere det i
-<URL:<a href="https://opencorporates.com/">https://opencorporates.com/</a>> for analyse, så det bør ikke ha
-bruksbegresninger som gjør dette umulig.</p>
-</blockquote>
-
-<p>To dager senere fikk jeg svar, med de datasettene de hadde
-tilgjengelig. Svaret fra Hanne Sekkelsten hos Medietilsynet var
-informativt og imøtekommende.</p>

- <div class="title"><a href="http://people.skolelinux.org/pere/blog/Graphing_the_Norwegian_company_ownership_structure.html">Graphing the Norwegian company ownership structure</a></div>
- <div class="date">15th June 2015</div>
- <div class="body"><p>It is a bit work to figure out the ownership structure of companies
-in Norway. The information is publicly available, but one need to
-recursively look up ownership for all owners to figure out the complete
-ownership graph of a given set of companies. To save me the work in
-the future, I wrote a script to do this automatically, outputting the
-ownership structure using the Graphviz/dotty format. The data source
-is web scraping from <a href="http://www.proff.no/">Proff</a>, because
-I failed to find a useful source directly from the official keepers of
-the ownership data, <a href="http://www.brreg.no/">Brønnøysundsregistrene</a>.</p>
-
-<p>To get an ownership graph for a set of companies, fetch
-<a href="https://github.com/petterreinholdtsen/brreg-norway-ownership-graph">the code from git</a> and run it using the organisation number. I'm
-using the Norwegian newspaper Dagbladet as an example here, as its
-ownership structure is very simple:</p>
-
-<pre>
-% time ./bin/eierskap-dotty 958033540 > dagbladet.dot
-
-real 0m2.841s
-user 0m0.184s
-sys 0m0.036s
-%
-</pre>
-
-<p>The script accept several organisation numbers on the command line,
-allowing a cluster of companies to be graphed in the same image. The
-resulting dot file for the example above look like this. The edges
-are labeled with the ownership percentage, and the nodes uses the
-organisation number as their name and the name as the label:</p>
-
-<pre>
-digraph ownership {
-rankdir = LR;
-"Aller Holding A/s" -> "910119877" [label="100%"]
-"910119877" -> "998689015" [label="100%"]
-"998689015" -> "958033540" [label="99%"]
-"974530600" -> "958033540" [label="1%"]
-"958033540" [label="AS DAGBLADET"]
-"998689015" [label="Berner Media Holding AS"]
-"974530600" [label="Dagbladets Stiftelse"]
-"910119877" [label="Aller Media AS"]
-}
-</pre>
-
-<p>To view the ownership graph, run "<tt>dotty dagbladet.dot</tt>" or
-convert it to a PNG using "<tt>dot -T png dagbladet.dot >
-dagbladet.png</tt>". The result can be seen below:</p>
-
-<img src="http://people.skolelinux.org/pere/blog/images/2015-06-15-ownership-graphs-norway-dagbladet.png" width="80%">
-
-<p>Note that I suspect the "Aller Holding A/S" entry to be incorrect
-data in the official ownership register, as that name is not
-registered in the official company register for Norway. The ownership
-register is sensitive to typos and there seem to be no strict checking
-of the ownership links.</p>
-
-<p>Let me know if you improve the script or find better data sources.
-The code is licensed according to GPL 2 or newer.</p>
-
-<p>Update 2015-06-15: Since the initial post I've been told that
-"<a href="http://www.proff.dk/firma/carl-allers-etablissement-aktieselskab/københavn-v/hovedkontorer/13624518-3/">Aller
-Holding A/S</a>" is a Danish company, which explain why it did not
-have a Norwegian organisation number. I've also been told that there
-is a <a href="http://www.brreg.no/automatiske/webservices/">web
-services API available</a> from Brønnøysundsregistrene, for those
-willing to accept the terms or pay the price.</p>

- <div class="date">11th June 2015</div>
- <div class="body"><p>Television loudness is the source of frustration for viewers
-everywhere. Some channels are very load, others are less loud, and
-ads tend to shout very high to get the attention of the viewers, and
-the viewers do not like this. This fact is well known to the TV
-channels. See for example the BBC white paper
-"<a href="http://downloads.bbc.co.uk/rd/pubs/whp/whp-pdf-files/WHP202.pdf">Terminology
-for loudness and level dBTP, LU, and all that</a>" from 2011 for a
-summary of the problem domain. To better address the need for even
-loadness, the TV channels got together several years ago to agree on a
-new way to measure loudness in digital files as one step in
-standardizing loudness. From this came the ITU-R standard BS.1770,
-"<a href="http://www.itu.int/rec/R-REC-BS.1770/en">Algorithms to
-measure audio programme loudness and true-peak audio level</a>".</p>
-
-<p>The ITU-R BS.1770 specification describe an algorithm to measure
-loadness in LUFS (Loudness Units, referenced to Full Scale). But
-having a way to measure is not enough. To get the same loudness
-across TV channels, one also need to decide which value to standardize
-on. For European TV channels, this was done in the EBU Recommondaton
-R128, "<a href="https://tech.ebu.ch/docs/r/r128.pdf">Loudness
-normalisation and permitted maximum level of audio signals</a>", which
-specifies a recommended level of -23 LUFS. In Norway, I have been
-told that NRK, TV2, MTG and SBS have decided among themselves to
-follow the R128 recommondation for playout from 2016-03-01.</p>
-
-<p>There are free software available to measure and adjust the loudness
-level using the LUFS. In Debian, I am aware of a library named
-<a href="https://tracker.debian.org/pkg/libebur128">libebur128</a>
-able to measure the loudness and since yesterday morning a new binary
-named <a href="http://bs1770gain.sourceforge.net">bs1770gain</a>
-capable of both measuring and adjusting was uploaded and is waiting
-for NEW processing. I plan to maintain the latter in Debian under the
-<a href="https://qa.debian.org/developer.php?email=pkg-multimedia-maintainers%40lists.alioth.debian.org">Debian
-multimedia</a> umbrella.</p>
-
-<p>The free software based TV channel I am involved in,
-<a href="http://www.frikanalen.no/">Frikanalen</a>, plan to follow the
-R128 recommondation ourself as soon as we can adjust the software to
-do so, and the bs1770gain tool seem like a good fit for that part of
-the puzzle to measure loudness on new video uploaded to Frikanalen.
-Personally, I plan to use bs1770gain to adjust the loudness of videos
-I upload to Frikanalen on behalf of <a href="http://www.nuug.no/">the
-NUUG member organisation</a>. The program seem to be able to measure
-the LUFS value of any media file handled by ffmpeg, but I've only
-successfully adjusted the LUFS value of WAV files. I suspect it
-should be able to adjust it for all the formats handled by ffmpeg.</p>
