- <description><p>Last year, <a href="https://lessig2016.us/">US president candidate
-in the Democratic Party</a> Lawrence interviewed Edward Snowden. The
-one hour interview was
-<a href="https://www.youtube.com/watch?v=o_Sr96TFQQE">published by
-Harvard Law School 2014-10-23 on Youtube</a>, and the meeting took
-place 2014-10-20.</p>
-
-<p>The questions are very good, and there is lots of useful
-information to be learned and very interesting issues to think about
-being raised. Please check it out.</p>

-
-<p>I find it especially interesting to hear again that Snowden did try
-to bring up his reservations through the official channels without any
-luck. It is in sharp contrast to the answers made by the Norwegian
-prime minister Erna Solberg said 2013-11-06 to the Norwegian
-Parliament,
-<a href="https://tale.holderdeord.no/speeches/s131106/68">claiming
-Snowden is no Whistle-Blower</a> because he should have taken up his
-concerns internally and using official channels. It make me sad
-that this is the political leadership we have here in Norway.</p>

+ <description><p>En av dagens nyheter er at Aftenpostens redaktør Espen Egil Hansen
+bruker
+<a href="https://www.nrk.no/kultur/aftenposten-brukar-heile-forsida-pa-facebook-kritikk-1.13126918">forsiden
+av papiravisen på et åpent brev til Facebooks sjef Mark Zuckerberg om
+Facebooks fjerning av bilder, tekster og sider de ikke liker</a>. Det
+må være uvant for redaktøren i avisen Aftenposten å stå med lua i
+handa og håpe på å bli hørt. Spesielt siden Aftenposten har vært med
+på å gi Facebook makten de nå demonstrerer at de har. Ved å melde seg
+inn i Facebook-samfunnet har de sagt ja til bruksvilkårene og inngått
+en antagelig bindende avtale. Kanskje de skulle lest og vurdert
+vilkårene litt nærmere før de sa ja, i stedet for å klage over at
+reglende de har valgt å akseptere blir fulgt? Personlig synes jeg
+vilkårene er uakseptable og det ville ikke falle meg inn å gå inn på
+en avtale med slike vilkår. I tillegg til uakseptable vilkår er det
+mange andre grunner til å unngå Facebook. Du kan finne en solid
+gjennomgang av flere slike argumenter hos
+<a href="https://stallman.org/facebook.html">Richard Stallmans side om
+Facebook</a>.
+
+<p>Jeg håper flere norske redaktører på samme vis må stå med lua i
+hånden inntil de forstår at de selv er med på å føre samfunnet på
+ville veier ved å omfavne Facebook slik de gjør når de omtaler og
+løfter frem saker fra Facebook, og tar i bruk Facebook som
+distribusjonskanal for sine nyheter. De bidrar til
+overvåkningssamfunnet og raderer ut lesernes privatsfære når de lenker
+til Facebook på sine sider, og låser seg selv inne i en omgivelse der
+det er Facebook, og ikke redaktøren, som sitter med makta.</p>
+
+<p>Men det vil nok ta tid, i et Norge der de fleste nettredaktører
+<a href="http://people.skolelinux.org/pere/blog/Snurpenot_overv_kning_av_sensitiv_personinformasjon.html">deler
+sine leseres personopplysinger med utenlands etterretning</a>.</p>
+
+<p>For øvrig burde varsleren Edward Snowden få politisk asyl i
+Norge.</p>

- <description><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. Aaron 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>

+ <description><p>I helga kom det et hårreisende forslag fra Lysne II-utvalget satt
+ned av Forsvarsdepartementet. Lysne II-utvalget var bedt om å vurdere
+ønskelista til Forsvarets etterretningstjeneste (e-tjenesten), og har
+kommet med
+<a href="http://www.aftenposten.no/norge/Utvalg-sier-ja-til-at-E-tjenesten-far-overvake-innholdet-i-all-internett--og-telefontrafikk-som-krysser-riksgrensen-603232b.html">forslag
+om at e-tjenesten skal få lov til a avlytte all Internett-trafikk</a>
+som passerer Norges grenser. Få er klar over at dette innebærer at
+e-tjenesten får tilgang til epost sendt til de fleste politiske
+partiene på Stortinget. Regjeringspartiet Høyre (@hoyre.no),
+støttepartiene Venstre (@venstre.no) og Kristelig Folkeparti (@krf.no)
+samt Sosialistisk Ventreparti (@sv.no) og Miljøpartiet de grønne
+(@mdg.no) har nemlig alle valgt å ta imot eposten sin via utenlandske
+tjenester. Det betyr at hvis noen sender epost til noen med en slik
+adresse vil innholdet i eposten, om dette forslaget blir vedtatt, gjøres
+tilgjengelig for e-tjenesten. Venstre, Sosialistisk Ventreparti og
+Miljøpartiet De Grønne har valgt å motta sin epost hos Google,
+Kristelig Folkeparti har valgt å motta sin epost hos Microsoft, og
+Høyre har valgt å motta sin epost hos Comendo med mottak i Danmark og
+Irland. Kun Arbeiderpartiet og Fremskrittspartiet har valgt å motta
+eposten sin i Norge, hos henholdsvis Intility AS og Telecomputing
+AS.</p>
+
+<p>Konsekvensen er at epost inn og ut av de politiske organisasjonene,
+til og fra partimedlemmer og partiets tillitsvalgte vil gjøres
+tilgjengelig for e-tjenesten for analyse og sortering. Jeg mistenker
+at kunnskapen som slik blir tilgjengelig vil være nyttig hvis en
+ønsker å vite hvilke argumenter som treffer publikum når en ønsker å
+påvirke Stortingets representanter.</p
+
+<p>Ved hjelp av MX-oppslag i DNS for epost-domene, tilhørende
+whois-oppslag av IP-adressene og traceroute for å se hvorvidt
+trafikken går via utlandet kan enhver få bekreftet at epost sendt til
+de omtalte partiene vil gjøres tilgjengelig for forsvarets
+etterretningstjeneste hvis forslaget blir vedtatt. En kan også bruke
+den kjekke nett-tjenesten <a href="http://ipinfo.io/">ipinfo.io</a>
+for å få en ide om hvor i verden en IP-adresse hører til.</p>
+
+<p>På den positive siden vil forslaget gjøre at enda flere blir
+motivert til å ta grep for å bruke
+<a href="https://www.torproject.org/">Tor</a> og krypterte
+kommunikasjonsløsninger for å kommunisere med sine kjære, for å sikre
+at privatsfæren vernes. Selv bruker jeg blant annet
+<a href="https://www.freedomboxfoundation.org/">FreedomBox</a> og
+<a href="https://whispersystems.org/">Signal</a> til slikt. Ingen av
+dem er optimale, men de fungerer ganske bra allerede og øker kostnaden
+for dem som ønsker å invadere mitt privatliv.</p>
+
+<p>For øvrig burde varsleren Edward Snowden få politisk asyl i
+Norge.</p>

- <pubDate>Wed, 7 Oct 2015 09:55:00 +0200</pubDate>
- <description><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>

+ <description><p>In April we
+<a href="http://people.skolelinux.org/pere/blog/Lets_make_a_Norwegian_Bokm_l_edition_of_The_Debian_Administrator_s_Handbook.html">started
+to work</a> on a Norwegian Bokmål edition of the "open access" book on
+how to set up and administrate a Debian system. Today I am happy to
+report that the first draft is now publicly available. You can find
+it on <a href="https://debian-handbook.info/get/">get the Debian
+Administrator's Handbook page</a> (under Other languages). The first
+eight chapters have a first draft translation, and we are working on
+proofreading the content. If you want to help out, please start
+contributing using
+<a href="https://hosted.weblate.org/projects/debian-handbook/">the
+hosted weblate project page</a>, and get in touch using
+<a href="http://lists.alioth.debian.org/mailman/listinfo/debian-handbook-translators">the
+translators mailing list</a>. Please also check out
+<a href="https://debian-handbook.info/contribute/">the instructions for
+contributors</a>. A good way to contribute is to proofread the text
+and update weblate if you find errors.</p>
+
+<p>Our goal is still to make the Norwegian book available on paper as well as
+electronic form.</p>

- <description><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
-<a href="http://www.wikilivres.ca/wiki/Culture_libre">Wikilivres wiki
-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

+ <description><p>This summer, I read a great article
+"<a href="https://www.usenix.org/publications/login/summer2016/curtsinger">coz:
+This Is the Profiler You're Looking For</a>" in USENIX ;login: about
+how to profile multi-threaded programs. It presented a system for
+profiling software by running experiences in the running program,
+testing how run time performance is affected by "speeding up" parts of
+the code to various degrees compared to a normal run. It does this by
+slowing down parallel threads while the "faster up" code is running
+and measure how this affect processing time. The processing time is
+measured using probes inserted into the code, either using progress
+counters (COZ_PROGRESS) or as latency meters (COZ_BEGIN/COZ_END). It
+can also measure unmodified code by measuring complete the program
+runtime and running the program several times instead.</p>
+
+<p>The project and presentation was so inspiring that I would like to
+get the system into Debian. I
+<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=830708">created
+a WNPP request for it</a> and contacted upstream to try to make the
+system ready for Debian by sending patches. The build process need to
+be changed a bit to avoid running 'git clone' to get dependencies, and
+to include the JavaScript web page used to visualize the collected
+profiling information included in the source package.
+But I expect that should work out fairly soon.</p>
+
+<p>The way the system work is fairly simple. To run an coz experiment
+on a binary with debug symbols available, start the program like this:
+
+<p><blockquote><pre>
+coz run --- program-to-run
+</pre></blockquote></p>
+
+<p>This will create a text file profile.coz with the instrumentation
+information. To show what part of the code affect the performance
+most, use a web browser and either point it to
+<a href="http://plasma-umass.github.io/coz/">http://plasma-umass.github.io/coz/</a>
+or use the copy from git (in the gh-pages branch). Check out this web
+site to have a look at several example profiling runs and get an idea what the end result from the profile runs look like. To make the
+profiling more useful you include &lt;coz.h&gt; and insert the
+COZ_PROGRESS or COZ_BEGIN and COZ_END at appropriate places in the
+code, rebuild and run the profiler. This allow coz to do more
+targeted experiments.</p>
+
+<p>A video published by ACM
+<a href="https://www.youtube.com/watch?v=jE0V-p1odPg">presenting the
+Coz profiler</a> is available from Youtube. There is also a paper
+from the 25th Symposium on Operating Systems Principles available
+titled
+<a href="https://www.usenix.org/conference/atc16/technical-sessions/presentation/curtsinger">Coz:
+finding code that counts with causal profiling</a>.</p>
+
+<p><a href="https://github.com/plasma-umass/coz">The source code</a>
+for Coz is available from github. It will only build with clang
+because it uses a
+<a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=55606">C++
+feature missing in GCC</a>, but I've submitted
+<a href="https://github.com/plasma-umass/coz/pull/67">a patch to solve
+it</a> and hope it will be included in the upstream source soon.</p>
+
+<p>Please get in touch if you, like me, would like to see this piece
+of software in Debian. I would very much like some help with the
+packaging effort, as I lack the in depth knowledge on how to package
+C++ libraries.</p>

- <title>The life and death of a laptop battery</title>
- <link>http://people.skolelinux.org/pere/blog/The_life_and_death_of_a_laptop_battery.html</link>
- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/The_life_and_death_of_a_laptop_battery.html</guid>
- <pubDate>Thu, 24 Sep 2015 16:00:00 +0200</pubDate>
- <description><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,
-[...]
-1443090528,LGC,45N1025,Li-ion,974,4900000,62160000,4900000,0,Full,
-1443090601,LGC,45N1025,Li-ion,974,4900000,62160000,4900000,0,Full,
-</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>

+ <description><p>As my regular readers probably remember, the last year I published
+a French and Norwegian translation of the classic
+<a href="http://www.free-culture.cc/">Free Culture book</a> by the
+founder of the Creative Commons movement, Lawrence Lessig. A bit less
+known is the fact that due to the way I created the translations,
+using docbook and po4a, I also recreated the English original. And
+because I already had created a new the PDF edition, I published it
+too. The revenue from the books are sent to the Creative Commons
+Corporation. In other words, I do not earn any money from this
+project, I just earn the warm fuzzy feeling that the text is available
+for a wider audience and more people can learn why the Creative
+Commons is needed.</p>
+
+<p>Today, just for fun, I had a look at the sales number over at
+Lulu.com, which take care of payment, printing and shipping. Much to
+my surprise, the English edition is selling better than both the
+French and Norwegian edition, despite the fact that it has been
+available in English since it was first published. In total, 24 paper
+books was sold for USD $19.99 between 2016-01-01 and 2016-07-31:</p>
+
+<table border="0">
+<tr><th>Title / language</th><th>Quantity</th></tr>
+<tr><td><a href="http://www.lulu.com/shop/lawrence-lessig/culture-libre/paperback/product-22645082.html">Culture Libre / French</a></td><td align="right">3</td></tr>
+<tr><td><a href="http://www.lulu.com/shop/lawrence-lessig/fri-kultur/paperback/product-22441576.html">Fri kultur / Norwegian</a></td><td align="right">7</td></tr>
+<tr><td><a href="http://www.lulu.com/shop/lawrence-lessig/free-culture/paperback/product-22440520.html">Free Culture / English</a></td><td align="right">14</td></tr>
+</table>
+
+<p>The books are available both from Lulu.com and from large book
+stores like Amazon and Barnes&Noble. Most revenue, around $10 per
+book, is sent to the Creative Commons project when the book is sold
+directly by Lulu.com. The other channels give less revenue. The
+summary from Lulu tell me 10 books was sold via the Amazon channel, 10
+via Ingram (what is this?) and 4 directly by Lulu. And Lulu.com tells
+me that the revenue sent so far this year is USD $101.42. No idea
+what kind of sales numbers to expect, so I do not know if that is a
+good amount of sales for a 10 year old book or not. But it make me
+happy that the buyers find the book, and I hope they enjoy reading it
+as much as I did.</p>
+
+<p>The ebook edition is available for free from
+<a href="https://github.com/petterreinholdtsen/free-culture-lessig">Github</a>.</p>
+
+<p>If you would like to translate and publish the book in your native
+language, I would be happy to help make it happen. Please get in
+touch.</p>

- <description><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>

+ <description><p>For mange år siden leste jeg en klassisk tekst som gjorde såpass
+inntrykk på meg at jeg husker den fortsatt, flere år senere, og bruker
+argumentene fra den stadig vekk. Teksten var «The Relativity of
+Wrong» som Isaac Asimov publiserte i Skeptical Inquirer i 1989. Den
+gir litt perspektiv rundt formidlingen av vitenskapelige resultater.
+Jeg har hatt lyst til å kunne dele den også med folk som ikke
+behersker engelsk så godt, som barn og noen av mine eldre slektninger,
+og har savnet å ha den tilgjengelig på norsk. For to uker siden tok
+jeg meg sammen og kontaktet Asbjørn Dyrendal i foreningen Skepsis om
+de var interessert i å publisere en norsk utgave på bloggen sin, og da
+han var positiv tok jeg kontakt med Skeptical Inquirer og spurte om
+det var greit for dem. I løpet av noen dager fikk vi tilbakemelding
+fra Barry Karr hos The Skeptical Inquirer som hadde sjekket og fått OK
+fra Robyn Asimov som representerte arvingene i Asmiov-familien og gikk
+igang med oversettingen.</p>
+
+<p>Resultatet, <a href="http://www.skepsis.no/?p=1617">«Relativt
+feil»</a>, ble publisert på skepsis-bloggen for noen minutter siden.
+Jeg anbefaler deg på det varmeste å lese denne teksten og dele den med
+dine venner.</p>
+
+<p>For å håndtere oversettelsen og sikre at original og oversettelse
+var i sync brukte vi git, po4a, GNU make og Transifex. Det hele
+fungerte utmerket og gjorde det enkelt å dele tekstene og jobbe sammen
+om finpuss på formuleringene. Hadde hosted.weblate.org latt meg
+opprette nye prosjekter selv i stedet for å måtte kontakte

- <description><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>

+<p>The TV channel is the Norwegian open channel
+<a href="http://www.frikanalen.no/">Frikanalen</a>, and I am involved
+via <a href="https://www.nuug.no/">the NUUG member association</a> in
+running and developing the software for the channel. The channel is
+organised as a member organisation where its members can upload and
+broadcast what they want (think of it as Youtube for national
+broadcasting television). Individuals can broadcast too. The time
+slots are handled on a first come, first serve basis. Because the
+channel have almost no viewers and very few active members, we can
+experiment with TV technology without too much flack when we make
+mistakes. And thanks to the few active members, most of the slots on
+the schedule are free. I see this as an opportunity to spread
+knowledge about technology and free software, and have a script I run
+regularly to fill up all the open slots the next few days with
+technology related video. The end result is a channel I like to
+describe as Techno TV - filled with interesting talks and
+presentations.</p>
+
+<p>It is available on channel 50 on the Norwegian national digital TV
+network (RiksTV). It is also available as a multicast stream on
+Uninett. And finally, it is available as
+<a href="http://beta.frikanalen.no/">a WebM unicast stream</a> from
+Frikanalen and NUUG. Check it out. :)</p>

- <description><p>Typesetting a book is harder than I hoped. As the translation is
-mostly done, and a volunteer proof reader was going to check the text
-on paper, it was time this summer to focus on formatting my translated
-<a href="http://www.docbook.org/">docbook</a> based version of the
-<a href="http://free-culture.cc/">Free Culture</a> book by Lawrence
-Lessig. I've been trying to get both docboox-xsl+fop and dblatex to
-give me a good looking PDF, but in the end I went with dblatex, because
-its Debian maintainer and upstream developer were responsive and very
-helpful in solving my formatting challenges.</p>
-
-<p>Last night, I finally managed to create a PDF that no longer made
-<a href="http://www.lulu.com/">Lulu.com</a> complain after uploading,
-and I ordered a text version of the book on paper. It is lacking a
-proper book cover and is not tagged with the correct ISBN number, but
-should give me an idea what the finished book will look like.</p>
-
-<p>Instead of using Lulu, I did consider printing the book using
-<a href="http://www.createspace.com/">CreateSpace</a>, but ended up
-using Lulu because it had smaller book size options (CreateSpace seem
-to lack pocket book with extended distribution). I looked for a
-similar service in Norway, but have not seen anything so far. Please
-let me know if I am missing out on something here.</p>
-
-<p>But I still struggle to decide the book size. Should I go for
-pocket book (4.25x6.875 inches / 10.8x17.5 cm) with 556 pages, Digest
-(5.5x8.5 inches / 14x21.6 cm) with 323 pages or US Trade (6x8 inches /
-15.3x22.9 cm) with 280 pages? Fewer pager give a cheaper book, and a
-smaller book is easier to carry around. The test book I ordered was
-pocket book sized, to give me an idea how well that fit in my hand,
-but I suspect I will end up using a digest sized book in the end to
-bring the prize down further.</p>
-
-<p>My biggest challenge at the moment is making nice cover art. My
-inkscape skills are not yet up to the task of replicating the original
-cover in SVG format. I also need to figure out what to write about
-the book on the back (will most likely use the same text as the
-description on web based book stores). I would love help with this,
-if you are willing to license the art source and final version using
-the same CC license as the book. My artistic skills are not really up
-to the task.</p>
-
-<p>I plan to publish the book in both English and Norwegian and on
-paper, in PDF form as well as EPUB and MOBI format. The current
-status can as usual be found on
-<a href="https://github.com/petterreinholdtsen/free-culture-lessig">github</a>
-in the archive/ directory. So far I have spent all time on making the
-PDF version look good. Someone should probably do the same with the
-dbtoepub generated e-book. Help is definitely needed here, as I
-expect to run out of steem before I find time to improve the epub
-formatting.</p>
-
-<p>Please let me know via github if you find typos in the book or
-discover translations that should be improved. The final proof
-reading is being done right now, and I expect to publish the finished
-result in a few months.</p>

+ <pubDate>Thu, 7 Jul 2016 11:30:00 +0200</pubDate>
+ <description><p>Yesterday, I tried to unlock a HTC Desire HD phone, and it proved
+to be a slight challenge. Here is the recipe if I ever need to do it
+again. It all started by me wanting to try the recipe to set up
+<a href="https://blog.torproject.org/blog/mission-impossible-hardening-android-security-and-privacy">an
+hardened Android installation</a> from the Tor project blog on a
+device I had access to. It is a old mobile phone with a broken
+microphone The initial idea had been to just
+<a href="http://wiki.cyanogenmod.org/w/Install_CM_for_ace">install
+CyanogenMod on it</a>, but did not quite find time to start on it
+until a few days ago.</p>
+
+<p>The unlock process is supposed to be simple: (1) Boot into the boot
+loader (press volume down and power at the same time), (2) select
+'fastboot' before (3) connecting the device via USB to a Linux
+machine, (4) request the device identifier token by running 'fastboot
+oem get_identifier_token', (5) request the device unlocking key using
+the <a href="http://www.htcdev.com/bootloader/">HTC developer web
+site</a> and unlock the phone using the key file emailed to you.</p>
+
+<p>Unfortunately, this only work fi you have hboot version 2.00.0029
+or newer, and the device I was working on had 2.00.0027. This
+apparently can be easily fixed by downloading a Windows program and
+running it on your Windows machine, if you accept the terms Microsoft
+require you to accept to use Windows - which I do not. So I had to
+come up with a different approach. I got a lot of help from AndyCap
+on #nuug, and would not have been able to get this working without
+him.</p>
+
+<p>First I needed to extract the hboot firmware from
+<a href="http://www.htcdev.com/ruu/PD9810000_Ace_Sense30_S_hboot_2.00.0029.exe">the
+windows binary for HTC Desire HD</a> downloaded as 'the RUU' from HTC.
+For this there is is <a href="https://github.com/kmdm/unruu/">a github
+project named unruu</a> using libunshield. The unshield tool did not
+recognise the file format, but unruu worked and extracted rom.zip,
+containing the new hboot firmware and a text file describing which
+devices it would work for.</p>
+
+<p>Next, I needed to get the new firmware into the device. For this I
+followed some instructions
+<a href="http://www.htc1guru.com/2013/09/new-ruu-zips-posted/">available
+from HTC1Guru.com</a>, and ran these commands as root on a Linux
+machine with Debian testing:</p>
+
+<p><pre>
+adb reboot-bootloader
+fastboot oem rebootRUU
+fastboot flash zip rom.zip
+fastboot flash zip rom.zip
+fastboot reboot
+</pre></p>
+
+<p>The flash command apparently need to be done twice to take effect,
+as the first is just preparations and the second one do the flashing.
+The adb command is just to get to the boot loader menu, so turning the
+device on while holding volume down and the power button should work
+too.</p>
+
+<p>With the new hboot version in place I could start following the
+instructions on the HTC developer web site. I got the device token
+like this:</p>
+
+<p><pre>
+fastboot oem get_identifier_token 2>&1 | sed 's/(bootloader) //'
+</pre>
+
+<p>And once I got the unlock code via email, I could use it like
+this:</p>
+
+<p><pre>
+fastboot flash unlocktoken Unlock_code.bin
+</pre></p>
+
+<p>And with that final step in place, the phone was unlocked and I
+could start stuffing the software of my own choosing into the device.
+So far I only inserted a replacement recovery image to wipe the phone
+before I start. We will see what happen next. Perhaps I should
+install <a href="https://www.debian.org/">Debian</a> on it. :)</p>

- <title>Typesetting DocBook footnotes as endnotes with dblatex</title>

- <description><p>I'm still working on the Norwegian version of the
-<a href="http://free-culture.cc/">Free Culture book by Lawrence
-Lessig</a>, and is now working on the final typesetting and layout.
-One of the features I want to get the structure similar to the
-original book is to typeset the footnotes as endnotes in the notes
-chapter. Based on the
-<a href="https://bugs.debian.org/685063">feedback from the Debian
-maintainer and the dblatex developer</a>, I came up with this recipe I
-would like to share with you. The proposal was to create a new LaTeX
-class file and add the LaTeX code there, but this is not always
-practical, when I want to be able to replace the class using a make
-file variable. So my proposal misuses the latex.begindocument XSL
-parameter value, to get a small fragment into the correct location in
-the generated LaTeX File.</p>
-
-<p>First, decide where in the DocBook document to place the endnotes,
-and add this text there:</p>

+ <description><p>For a while now, I have wanted to test
+<a href="https://whispersystems.org/">the Signal app</a>, as it is
+said to provide end to end encrypted communication and several of my
+friends and family are already using it. As I by choice do not own a
+mobile phone, this proved to be harder than expected. And I wanted to
+have the source of the client and know that it was the code used on my
+machine. But yesterday I managed to get it working. I used the
+Github source, compared it to the source in
+<a href="https://chrome.google.com/webstore/detail/signal-private-messenger/bikioccmkafdpakkkcpdbppfkghcmihk?hl=en-US">the
+Signal Chrome app</a> available from the Chrome web store, applied
+patches to use the production Signal servers, started the app and
+asked for the hidden "register without a smart phone" form. Here is
+the recipe how I did it.</p>
+
+<p>First, I fetched the Signal desktop source from Github, using
<pre>
-&lt;?latex \theendnotes ?&gt;
+git clone https://github.com/WhisperSystems/Signal-Desktop.git
</pre>
-<p>Next, create a xsl stylesheet file dblatex-endnotes.xsl to add the
-code needed to add the endnote instructions in the preamble of the
-generated LaTeX document, with content like this:</p>
+<p>Next, I patched the source to use the production servers, to be
+able to talk to other Signal users:</p>
<pre>
-&lt;?xml version='1.0'?&gt;
-&lt;xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'&gt;
- &lt;xsl:param name="latex.begindocument"&gt;
- &lt;xsl:text&gt;
-\usepackage{endnotes}
-\let\footnote=\endnote
-\def\enoteheading{\mbox{}\par\vskip-\baselineskip }
-\begin{document}
- &lt;/xsl:text&gt;
- &lt;/xsl:param&gt;
-&lt;/xsl:stylesheet&gt;

-<p>Finally, load this xsl file when running dblatex, for example like
-this:</p>
+<p>The first part is changing the servers, and the second is updating
+an expiration timestamp. This timestamp need to be updated regularly.
+It is set 90 days in the future by the build process (Gruntfile.js).
+The value is seconds since 1970 times 1000, as far as I can tell.</p>
+
+<p>Based on a tip and good help from the #nuug IRC channel, I wrote a
+script to launch Signal in Chromium.</p>
<pre>
-dblatex --xsl-user=dblatex-endnotes.xsl freeculture.nb.xml
+#!/bin/sh
+cd $(dirname $0)
+mkdir -p userdata
+exec chromium \
+ --proxy-server="socks://localhost:9050" \
+ --user-data-dir=`pwd`/userdata --load-and-launch-app=`pwd`
</pre>
-<p>The end result can be seen on github, where
-<a href="https://github.com/petterreinholdtsen/free-culture-lessig">my
-book project</a> is located.</p>
+<p> The script start the app and configure Chromium to use the Tor
+SOCKS5 proxy to make sure those controlling the Signal servers (today
+Amazon and Whisper Systems) as well as those listening on the lines
+will have a harder time location my laptop based on the Signal
+connections if they use source IP address.</p>
+
+<p>When the script starts, one need to follow the instructions under
+"Standalone Registration" in the CONTRIBUTING.md file in the git
+repository. I right clicked on the Signal window to get up the
+Chromium debugging tool, visited the 'Console' tab and wrote
+'extension.install("standalone")' on the console prompt to get the
+registration form. Then I entered by land line phone number and
+pressed 'Call'. 5 seconds later the phone rang and a robot voice
+repeated the verification code three times. After entering the number
+into the verification code field in the form, I could start using
+Signal from my laptop.
+
+<p>As far as I can tell, The Signal app will leak who is talking to
+whom and thus who know who to those controlling the central server,
+but such leakage is hard to avoid with a centrally controlled server
+setup. It is something to keep in mind when using Signal - the
+content of your chats are harder to intercept, but the meta data
+exposing your contact network is available to people you do not know.
+So better than many options, but not great. And sadly the usage is
+connected to my land line, thus allowing those controlling the server
+to associate it to my home and person. I would prefer it if only
+those I knew could tell who I was on Signal. There are options
+avoiding such information leakage, but most of my friends are not
+using them, so I am stuck with Signal for now.</p>

- <description><p>I går fikk vi endelig lansert en norsk version av mySocietys
-<a href="https://www.whatdotheyknow.com/">WhatDoTheyKnow</a>.
-Tjenesten heter Mimes brønn, og ble
-<a href="http://www.nuug.no/news/NUUG_lanserer_innsynstjenesten_Mimes_Br_nn.shtml">annonsert
-av NUUG</a> via blogg, epost og twitter til NUUG-assosierte personer.
-Det har tatt noen år, men de siste dagene fikk vi endelig tid til å få
-på plass de siste bitene. Vi er to, Gorm og meg selv, som har vært
-primus motor for det hele, men vi har fått hjelp med oversettelser og
-oppsett fra mange flere. Jeg vil si tusen takk til hver og en av dem,
-og er veldig fornøyd med at vi klarte å få tjenesten opp å kjøre før
-ferietiden slo inn for fullt.</p>
-
-<p>Vi er usikker på hvor mye belastning den virtuelle maskinen der
-tjenesten kjører klarer, så vi har lansert litt i det stille og ikke
-til for mange folk for å se hvordan maskinen klarer seg over sommeren,
-før vi går mer aktivt ut og annonserer til høsten. Ta en titt, og se
-om du kanskje har et spørsmål til det offentlige som er egnet å sende
-inn via Mimes brønn.</p>
-
-<p>Hvis du lurer på hva i alle dager en slik tjenestes kan brukes til,
-anbefaler jeg deg å se
-<a href="http://beta.frikanalen.no/video/625321">TED-foredraget til
-Heather Brook</a> om hvordan hun brukte WhatDoTheyKnow til å lære
-hvordan offentlige midler ble misbrukt. Det er en inspirerende

+ <pubDate>Mon, 6 Jun 2016 12:50:00 +0200</pubDate>
+ <description><p>When I set out a few weeks ago to figure out
+<a href="http://people.skolelinux.org/pere/blog/What_is_the_best_multimedia_player_in_Debian_.html">which
+multimedia player in Debian claimed to support most file formats /
+MIME types</a>, I was a bit surprised how varied the sets of MIME types
+the various players claimed support for. The range was from 55 to 130
+MIME types. I suspect most media formats are supported by all
+players, but this is not really reflected in the MimeTypes values in
+their desktop files. There are probably also some bogus MIME types
+listed, but it is hard to identify which one this is.</p>
+
+<p>Anyway, in the mean time I got in touch with upstream for some of
+the players suggesting to add more MIME types to their desktop files,
+and decided to spend some time myself improving the situation for my
+favorite media player VLC. The fixes for VLC entered Debian unstable
+yesterday. The complete list of MIME types can be seen on the
+<a href="https://wiki.debian.org/DebianMultimedia/PlayerSupport">Multimedia
+player MIME type support status</a> Debian wiki page.</p>
+
+<p>The new "best" multimedia player in Debian? It is VLC, followed by
+totem, parole, kplayer, gnome-mpv, mpv, smplayer, mplayer-gui and
+kmplayer. I am sure some of the other players desktop files support
+several of the formats currently listed as working only with vlc,
+toten and parole.</p>
+
+<p>A sad observation is that only 14 MIME types are listed as
+supported by all the tested multimedia players in Debian in their
+desktop files: audio/mpeg, audio/vnd.rn-realaudio, audio/x-mpegurl,
+audio/x-ms-wma, audio/x-scpls, audio/x-wav, video/mp4, video/mpeg,
+video/quicktime, video/vnd.rn-realvideo, video/x-matroska,
+video/x-ms-asf, video/x-ms-wmv and video/x-msvideo. Personally I find
+it sad that video/ogg and video/webm is not supported by all the media
+players in Debian. As far as I can tell, all of them can handle both
+formats.</p>
