- <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="date"> 3rd July 2015</div>
- <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
-have suggestions.</p>
-
-<p>Update 2015-07-23: I got a suggestion to check out the FSF
-<a href="http://www.fsf.org/resources/hw/endorsement/respects-your-freedom">list
-of endorsed hardware</a>, which is useful background information.</p>

- <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://hotell.difi.no/">http://hotell.difi.no/</a>> uten å
-finne noe der, og fant heller ikke noe under

-
-<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>

- <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>
