- <description><p>Making packages for Debian requires quite a lot of attention to
-details. And one of the details is the content of the
-debian/copyright file, which should list all relevant licenses used by
-the code in the package in question, preferably in
-<a href="https://www.debian.org/doc/packaging-manuals/copyright-format/1.0/">machine
-readable DEP5 format</a>.</p>
-
-<p>For large packages with lots of contributors it is hard to write
-and update this file manually, and if you get some detail wrong, the
-package is normally rejected by the ftpmasters. So getting it right
-the first time around get the package into Debian faster, and save
-both you and the ftpmasters some work.. Today, while trying to figure
-out what was wrong with
-<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=686447">the
-zfsonlinux copyright file</a>, I decided to spend some time on
-figuring out the options for doing this job automatically, or at least
-semi-automatically.</p>
-
-<p>Lucikly, there are at least two tools available for generating the
-file based on the code in the source package,
-<tt><a href="https://tracker.debian.org/pkg/debmake">debmake</a></tt>
-and <tt><a href="https://tracker.debian.org/pkg/cme">cme</a></tt>. I'm
-not sure which one of them came first, but both seem to be able to
-create a sensible draft file. As far as I can tell, none of them can
-be trusted to get the result just right, so the content need to be
-polished a bit before the file is OK to upload. I found the debmake
-option in
-<a href="http://goofying-with-debian.blogspot.com/2014/07/debmake-checking-source-against-dep-5.html">a
-blog posts from 2014</a>.
-
-<p>To generate using debmake, use the -cc option:
-
-<p><pre>
-debmake -cc > debian/copyright
-</pre></p>
-
-<p>Note there are some problems with python and non-ASCII names, so
-this might not be the best option.</p>
-
-<p>The cme option is based on a config parsing library, and I found
-this approach in
-<a href="https://ddumont.wordpress.com/2015/04/05/improving-creation-of-debian-copyright-file/">a
-blog post from 2015</a>. To generate using cme, use the 'update
-dpkg-copyright' option:
-
-<p><pre>
-cme update dpkg-copyright -quiet
-</pre></p>
-
-<p>This will create or update debian/copyright. The cme tool seem to
-handle UTF-8 names better than debmake.</p>
-
-<p>When the copyright file is created, I would also like some help to
-check if the file is correct. For this I found two good options,
-<tt>debmake -k</tt> and <tt>license-reconcile</tt>. The former seem
-to focus on license types and file matching, and is able to detect
-ineffective blocks in the copyright file. The latter reports missing
-copyright holders and years, but was confused by inconsistent license
-names (like CDDL vs. CDDL-1.0). I suspect it is good to use both and
-fix all issues reported by them before uploading. But I do not know
-if the tools and the ftpmasters agree on what is important to fix in a
-copyright file, so the package might still be rejected.</p>
-
-<p>The devscripts tool <tt>licensecheck</tt> deserve mentioning. It
-will read through the source and try to find all copyright statements.
-It is not comparing the result to the content of debian/copyright, but
-can be useful when verifying the content of the copyright file.</p>
-
-<p>Are you aware of better tools in Debian to create and update
-debian/copyright file. Please let me know, or blog about it on
-planet.debian.org.</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>
-
-<p><strong>Update 2016-02-20</strong>: I got a tip from Mike Gabriel
-on how to use licensecheck and cdbs to create a draft copyright file
-
-<p><pre>
-licensecheck --copyright -r `find * -type f` | \
- /usr/lib/cdbs/licensecheck2dep5 > debian/copyright.auto
-</pre></p>
-
-<p>He mentioned that he normally check the generated file into the
-version control system to make it easier to discover license and
-copyright changes in the upstream source. I will try to do the same
-with my packages in the future.</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>

- <title>Using appstream in Debian to locate packages with firmware and mime type support</title>

- <description><p>The <a href="https://wiki.debian.org/DEP-11">appstream system</a>
-is taking shape in Debian, and one provided feature is a very
-convenient way to tell you which package to install to make a given
-firmware file available when the kernel is looking for it. This can
-be done using apt-file too, but that is for someone else to blog
-about. :)</p>
-
-<p>Here is a small recipe to find the package with a given firmware
-file, in this example I am looking for ctfw-3.2.3.0.bin, randomly
-picked from the set of firmware announced using appstream in Debian
-unstable. In general you would be looking for the firmware requested
-by the kernel during kernel module loading. To find the package
-providing the example file, do like this:</p>
-
-<blockquote><pre>
-% apt install appstream
-[...]
-% apt update
-[...]
-% appstreamcli what-provides firmware:runtime ctfw-3.2.3.0.bin | \
- awk '/Package:/ {print $2}'
-firmware-qlogic
-%
-</pre></blockquote>
-
-<p>See <a href="https://wiki.debian.org/AppStream/Guidelines">the
-appstream wiki</a> page to learn how to embed the package metadata in
-a way appstream can use.</p>
-
-<p>This same approach can be used to find any package supporting a
-given MIME type. This is very useful when you get a file you do not
-know how to handle. First find the mime type using <tt>file
---mime-type</tt>, and next look up the package providing support for
-it. Lets say you got an SVG file. Its MIME type is image/svg+xml,
-and you can find all packages handling this type like this:</p>
-
-<blockquote><pre>
-% apt install appstream
-[...]
-% apt update
-[...]
-% appstreamcli what-provides mimetype image/svg+xml | \
- awk '/Package:/ {print $2}'
-bkchem
-phototonic
-inkscape
-shutter
-tetzle
-geeqie
-xia
-pinta
-gthumb
-karbon
-comix
-mirage
-viewnior
-postr
-ristretto
-kolourpaint4
-eog
-eom
-gimagereader
-midori
-%
-</pre></blockquote>
-
-<p>I believe the MIME types are fetched from the desktop file for
-packages providing appstream metadata.</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>

- <description><p>Most people seem not to realise that every time they walk around
-with the computerised radio beacon known as a mobile phone their
-position is tracked by the phone company and often stored for a long
-time (like every time a SMS is received or sent). And if their
-computerised radio beacon is capable of running programs (often called
-mobile apps) downloaded from the Internet, these programs are often
-also capable of tracking their location (if the app requested access
-during installation). And when these programs send out information to
-central collection points, the location is often included, unless
-extra care is taken to not send the location. The provided
-information is used by several entities, for good and bad (what is
-good and bad, depend on your point of view). What is certain, is that
-the private sphere and the right to free movement is challenged and
-perhaps even eradicated for those announcing their location this way,
-when they share their whereabouts with private and public
-entities.</p>
-
-<p align="center"><img width="70%" src="http://people.skolelinux.org/pere/blog/images/2016-01-24-nice-creepy-desktop-window.png"></p>
-
-<p>The phone company logs provide a register of locations to check out
-when one want to figure out what the tracked person was doing. It is
-unavailable for most of us, but provided to selected government
-officials, company staff, those illegally buying information from
-unfaithful servants and crackers stealing the information. But the
-public information can be collected and analysed, and a free software
-tool to do so is called
-<a href="http://www.geocreepy.com/">Creepy or Cree.py</a>. I
-discovered it when I read
-<a href="http://www.aftenposten.no/kultur/Slik-kan-du-bli-overvaket-pa-Twitter-og-Instagram-uten-a-ane-det-7787884.html">an
-article about Creepy</a> in the Norwegian newspaper Aftenposten i
-November 2014, and decided to check if it was available in Debian.
-The python program was in Debian, but
-<a href="https://tracker.debian.org/pkg/creepy">the version in
-Debian</a> was completely broken and practically unmaintained. I
-uploaded a new version which did not work quite right, but did not
-have time to fix it then. This Christmas I decided to finally try to
-get Creepy operational in Debian. Now a fixed version is available in
-Debian unstable and testing, and almost all Debian specific patches
-are now included
-<a href="https://github.com/jkakavas/creepy">upstream</a>.</p>
-
-<p>The Creepy program visualises geolocation information fetched from
-Twitter, Instagram, Flickr and Google+, and allow one to get a
-complete picture of every social media message posted recently in a
-given area, or track the movement of a given individual across all
-these services. Earlier it was possible to use the search API of at
-least some of these services without identifying oneself, but these
-days it is impossible. This mean that to use Creepy, you need to
-configure it to log in as yourself on these services, and provide
-information to them about your search interests. This should be taken
-into account when using Creepy, as it will also share information
-about yourself with the services.</p>
-
-<p>The picture above show the twitter messages sent from (or at least
-geotagged with a position from) the city centre of Oslo, the capital
-of Norway. One useful way to use Creepy is to first look at
-information tagged with an area of interest, and next look at all the
-information provided by one or more individuals who was in the area.
-I tested it by checking out which celebrity provide their location in
-twitter messages by checkout out who sent twitter messages near a
-Norwegian TV station, and next could track their position over time,
-making it possible to locate their home and work place, among other
-things. A similar technique have been
-<a href="http://www.buzzfeed.com/maxseddon/does-this-soldiers-instagram-account-prove-russia-is-covertl">used
-to locate Russian soldiers in Ukraine</a>, and it is both a powerful
-tool to discover lying governments, and a useful tool to help people
-understand the value of the private information they provide to the
-public.</p>
-
-<p>The package is not trivial to backport to Debian Stable/Jessie, as
-it depend on several python modules currently missing in Jessie (at
-least python-instagram, python-flickrapi and
-python-requests-toolbelt).</p>
-
-<p>(I have uploaded
-<a href="https://screenshots.debian.net/package/creepy">the image to
-screenshots.debian.net</a> and licensed it under the same terms as the
-Creepy program in Debian.)</p>

- <description><p>During his DebConf15 keynote, Jacob Appelbaum
-<a href="https://summit.debconf.org/debconf15/meeting/331/what-is-to-be-done/">observed
-that those listening on the Internet lines would have good reason to
-believe a computer have a given security hole</a> if it download a
-security fix from a Debian mirror. This is a good reason to always
-use encrypted connections to the Debian mirror, to make sure those
-listening do not know which IP address to attack. In August, Richard
-Hartmann observed that encryption was not enough, when it was possible
-to interfere download size to security patches or the fact that
-download took place shortly after a security fix was released, and
-<a href="http://richardhartmann.de/blog/posts/2015/08/24-Tor-enabled_Debian_mirror/">proposed
-to always use Tor to download packages from the Debian mirror</a>. He
-was not the first to propose this, as the
-<tt><a href="https://tracker.debian.org/pkg/apt-transport-tor">apt-transport-tor</a></tt>
-package by Tim Retout already existed to make it easy to convince apt
-to use <a href="https://www.torproject.org/">Tor</a>, but I was not
-aware of that package when I read the blog post from Richard.</p>
-
-<p>Richard discussed the idea with Peter Palfrader, one of the Debian
-sysadmins, and he set up a Tor hidden service on one of the central
-Debian mirrors using the address vwakviie2ienjx6t.onion, thus making
-it possible to download packages directly between two tor nodes,
-making sure the network traffic always were encrypted.</p>
-
-<p>Here is a short recipe for enabling this on your machine, by
-installing <tt>apt-transport-tor</tt> and replacing http and https
-urls with tor+http and tor+https, and using the hidden service instead
-of the official Debian mirror site. I recommend installing
-<tt>etckeeper</tt> before you start to have a history of the changes
-done in /etc/.</p>
-
-<blockquote><pre>
-apt install apt-transport-tor
-sed -i 's% http://ftp.debian.org/% tor+http://vwakviie2ienjx6t.onion/%' /etc/apt/sources.list
-sed -i 's% http% tor+http%' /etc/apt/sources.list
-</pre></blockquote>
-
-<p>If you have more sources listed in /etc/apt/sources.list.d/, run
-the sed commands for these too. The sed command is assuming your are
-using the ftp.debian.org Debian mirror. Adjust the command (or just
-edit the file manually) to match your mirror.</p>
-
-<p>This work in Debian Jessie and later. Note that tools like
-<tt>apt-file</tt> only recently started using the apt transport
-system, and do not work with these tor+http URLs. For
-<tt>apt-file</tt> you need the version currently in experimental,
-which need a recent apt version currently only in unstable. So if you
-need a working <tt>apt-file</tt>, this is not for you.</p>
-
-<p>Another advantage from this change is that your machine will start
-using Tor regularly and at fairly random intervals (every time you
-update the package lists or upgrade or install a new package), thus
-masking other Tor traffic done from the same machine. Using Tor will
-become normal for the machine in question.</p>
-
-<p>On <a href="https://wiki.debian.org/FreedomBox">Freedombox</a>, APT
-is set up by default to use <tt>apt-transport-tor</tt> when Tor is
-enabled. It would be great if it was the default on any Debian
-system.</p>

- <description><p>Det kommer stadig nye løsninger for å ta lagre unna innslag fra NRK
-for å se på det senere. For en stund tilbake kom jeg over et script

-
-<p>Scriptet kan lagre som MPEG4 eller Matroska, og bake inn

+ <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>

- <description><p>When I was a kid, we used to collect "car numbers", as we used to
-call the car license plate numbers in those days. I would write the
-numbers down in my little book and compare notes with the other kids
-to see how many region codes we had seen and if we had seen some
-exotic or special region codes and numbers. It was a fun game to pass
-time, as we kids have plenty of it.</p>
-
-<p>A few days I came across
-<a href="https://github.com/openalpr/openalpr">the OpenALPR
-project</a>, a free software project to automatically discover and
-report license plates in images and video streams, and provide the
-"car numbers" in a machine readable format. I've been looking for
-such system for a while now, because I believe it is a bad idea that the
-<a href="https://en.wikipedia.org/wiki/Automatic_number_plate_recognition">automatic
-number plate recognition</a> tool only is available in the hands of
-the powerful, and want it to be available also for the powerless to
-even the score when it comes to surveillance and sousveillance. I
-discovered the developer
-<a href="https://bugs.debian.org/747509">wanted to get the tool into
-Debian</a>, and as I too wanted it to be in Debian, I volunteered to
-help him get it into shape to get the package uploaded into the Debian
-archive.</p>
-
-<p>Today we finally managed to get the package into shape and uploaded
-it into Debian, where it currently
-<a href="https://ftp-master.debian.org//new/openalpr_2.2.1-1.html">waits
-in the NEW queue</a> for review by the Debian ftpmasters.</p>
-
-<p>I guess you are wondering why on earth such tool would be useful
-for the common folks, ie those not running a large government
-surveillance system? Well, I plan to put it in a computer on my bike
-and in my car, tracking the cars nearby and allowing me to be notified
-when number plates on my watch list are discovered. Another use case
-was suggested by a friend of mine, who wanted to set it up at his home
-to open the car port automatically when it discovered the plate on his
-car. When I mentioned it perhaps was a bit foolhardy to allow anyone
-capable of placing his license plate number of a piece of cardboard to
-open his car port, men replied that it was always unlocked anyway. I
-guess for such use case it make sense. I am sure there are other use
-cases too, for those with imagination and a vision.</p>
-
-<p>If you want to build your own version of the Debian package, check
-out the upstream git source and symlink ./distros/debian to ./debian/
-before running "debuild" to build the source. Or wait a bit until the
-package show up in unstable.</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>

- <title>Using appstream with isenkram to install hardware related packages in Debian</title>
- <link>http://people.skolelinux.org/pere/blog/Using_appstream_with_isenkram_to_install_hardware_related_packages_in_Debian.html</link>
- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Using_appstream_with_isenkram_to_install_hardware_related_packages_in_Debian.html</guid>
- <pubDate>Sun, 20 Dec 2015 12:20:00 +0100</pubDate>
- <description><p>Around three years ago, I created
-<a href="http://packages.qa.debian.org/isenkram">the isenkram
-system</a> to get a more practical solution in Debian for handing
-hardware related packages. A GUI system in the isenkram package will
-present a pop-up dialog when some hardware dongle supported by
-relevant packages in Debian is inserted into the machine. The same
-lookup mechanism to detect packages is available as command line
-tools in the isenkram-cli package. In addition to mapping hardware,
-it will also map kernel firmware files to packages and make it easy to
-install needed firmware packages automatically. The key for this
-system to work is a good way to map hardware to packages, in other
-words, allow packages to announce what hardware they will work
-with.</p>
-
-<p>I started by providing data files in the isenkram source, and
-adding code to download the latest version of these data files at run
-time, to ensure every user had the most up to date mapping available.
-I also added support for storing the mapping in the Packages file in
-the apt repositories, but did not push this approach because while I
-was trying to figure out how to best store hardware/package mappings,
-<a href="http://www.freedesktop.org/software/appstream/docs/">the
-appstream system</a> was announced. I got in touch and suggested to
-add the hardware mapping into that data set to be able to use
-appstream as a data source, and this was accepted at least for the
-Debian version of appstream.</p>
-
-<p>A few days ago using appstream in Debian for this became possible,
-and today I uploaded a new version 0.20 of isenkram adding support for
-appstream as a data source for mapping hardware to packages. The only
-package so far using appstream to announce its hardware support is my
-pymissile package. I got help from Matthias Klumpp with figuring out
-how do add the required
-<a href="https://appstream.debian.org/html/sid/main/metainfo/pymissile.html">metadata
-in pymissile</a>. I added a file debian/pymissile.metainfo.xml with
-this content:</p>
-
-<blockquote><pre>
-&lt;?xml version="1.0" encoding="UTF-8"?&gt;
-&lt;component&gt;
- &lt;id&gt;pymissile&lt;/id&gt;
- &lt;metadata_license&gt;MIT&lt;/metadata_license&gt;
- &lt;name&gt;pymissile&lt;/name&gt;
- &lt;summary&gt;Control original Striker USB Missile Launcher&lt;/summary&gt;
- &lt;description&gt;
- &lt;p&gt;
- Pymissile provides a curses interface to control an original
- Marks and Spencer / Striker USB Missile Launcher, as well as a
- motion control script to allow a webcamera to control the
- launcher.
- &lt;/p&gt;
- &lt;/description&gt;
- &lt;provides&gt;
- &lt;modalias&gt;usb:v1130p0202d*&lt;/modalias&gt;
- &lt;/provides&gt;
-&lt;/component&gt;
-</pre></blockquote>
-
-<p>The key for isenkram is the component/provides/modalias value,
-which is a glob style match rule for hardware specific strings
-(modalias strings) provided by the Linux kernel. In this case, it
-will map to all USB devices with vendor code 1130 and product code
-0202.</p>
-
-<p>Note, it is important that the license of all the metadata files
-are compatible to have permissions to aggregate them into archive wide
-appstream files. Matthias suggested to use MIT or BSD licenses for
-these files. A challenge is figuring out a good id for the data, as
-it is supposed to be globally unique and shared across distributions
-(in other words, best to coordinate with upstream what to use). But
-it can be changed later or, so we went with the package name as
-upstream for this project is dormant.</p>
-
-<p>To get the metadata file installed in the correct location for the
-mirror update scripts to pick it up and include its content the
-appstream data source, the file must be installed in the binary
-package under /usr/share/appdata/. I did this by adding the following
-line to debian/pymissile.install:</p>
-
-<blockquote><pre>
-debian/pymissile.metainfo.xml usr/share/appdata
-</pre></blockquote>
-
-<p>With that in place, the command line tool isenkram-lookup will list
-all packages useful on the current computer automatically, and the GUI
-pop-up handler will propose to install the package not already
-installed if a hardware dongle is inserted into the machine in
-question.</p>
-
-<p>Details of the modalias field in appstream is available from the
-<a href="https://wiki.debian.org/DEP-11">DEP-11</a> proposal.</p>
-
-<p>To locate the modalias values of all hardware present in a machine,
-try running this command on the command line:</p>
-
-<blockquote><pre>
-cat $(find /sys/devices/|grep modalias)
-</pre></blockquote>

+ <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
+administratoren der, så hadde jeg brukt weblate i stedet.</p>

-<a href="https://github.com/petterreinholdtsen/free-culture-lessig/">github</a>.</strong></p>
-
-<p>Jeg ble gledelig overrasket i dag da jeg oppdaget at boken jeg har
-gitt ut
-<a href="https://www.amazon.com/Fri-kultur-Norwegian-Lawrence-Lessig/dp/8269018236/">hadde
-dukket opp i Amazon</a>. Jeg hadde trodd det skulle ta lenger tid, da
-jeg fikk beskjed om at det skulle ta seks til åtte uker.
-Amazonoppføringen er et resultat av at jeg for noen uker siden
-diskuterte prissetting og håndtering av profitt med forfatteren. Det
-måtte avklares da bruksvilkårene til boken har krav om
-ikke-kommersiell bruk. Vi ble enige om at overskuddet fra salg av
-boken skal sendes til
-<a href="https://creativecommons.org/">Creative Commons-stiftelsen</a>.
-Med det på plass kunne jeg be
-<a href="https://www.lulu.com/shop/lawrence-lessig/fri-kultur/paperback/product-22441576.html">lulu.com</a>
-om å gi boken «utvidet» distribusjon. Årsaken til at
-bokhandeldistribusjon var litt utfordrende er at bokhandlere krever
-mulighet for profitt på bøkene de selger (selvfølgelig), og dermed
-måtte de få lov til å selge til høyere pris enn lulu.com. I tillegg
-er det krav om samme pris på lulu.com og i bokhandlene, dermed blir
-prisen økt også hos lulu.com. Hva skulle jeg gjøre med den profitten
-uten å bryte med klausulen om ikkekommersiell? Løsningen var å gi
-bort profitten til CC-stiftelsen. Prisen på boken ble nesten
-tredoblet, til $19.99 (ca. 160,-) pluss frakt, men synligheten øker
-betraktelig når den kan finnes i katalogene til store nettbokhandlere.
-Det betyr at hvis du allerede har kjøpt boken har du fått den veldig
-billig, og kjøper du den nå, får du den fortsatt billig samt donerer i
-tillegg noen tiere til fremme av Creative Commons.</p>
-
-<p>Mens jeg var i gang med å titte etter informasjon om boken
-oppdaget jeg at den også var dukket opp på
-<a href="https://books.google.no/books?id=uKUGCwAAQBAJ">Google
-Books</a>, der en kan lese den på web. PDF-utgaven har ennå ikke
-dukket opp hos <a href="https://www.nb.no/">Nasjonalbiblioteket</a>,
-men det regner jeg med kommer på plass i løpet av noen uker. Boken er
-heller ikke dukket opp hos
-<a href="https://www.barnesandnoble.com/">Barnes & Noble</a> ennå, men
-jeg antar det bare er et tidsspørsmål før dette er på plass.</p>
-
-<p>Boken er dessverre ikke tilgjengelig fra norske bokhandlere, og
-kommer neppe til å bli det med det første. Årsaken er at for å få det
-til måtte jeg personlig håndtere bestilling av bøker, hvilket jeg ikke
-er interessert i å bruke tid på. Jeg kunne betalt ca 2000,- til
-<a href="http://www.bokbasen.no/">den norske bokbasen</a>, en felles
-database over bøker tilgjengelig for norske bokhandlere, for å få en
-oppføring der, men da måtte jeg tatt imot bestillinger på epost og
-sendt ut bøker selv. Det ville krevd at jeg var klar til å
-sende ut bøker på kort varsel, dvs. holdt meg med ekstra bøker,
-konvolutter og frimerker. Bokbasen har visst ikke opplegg for å be
-bokhandlene bestille direkte via web, så jeg droppet oppføring der.
-Jeg har spurt Haugen bok og Tronsmo direkte på epost om de er
-interessert i å ta inn boken i sin bestillingskatalog, men ikke fått
-svar, så jeg antar de ikke er interessert. Derimot har jeg fått en
-hyggelig henvendelse fra Biblioteksentralen som fortalte at de har
-lagt den inn i sin database slik at deres bibliotekskunder enkelt kan
-bestille den via dem.</p>
-
-<p>Boken er i følge

+ <description><p>Did you know there is a TV channel broadcasting talks from DebConf
+16 across an entire country? Or that there is a TV channel
+broadcasting talks by or about
+<a href="http://beta.frikanalen.no/video/625529/">Linus Torvalds</a>,
+<a href="http://beta.frikanalen.no/video/625599/">Tor</a>,

+<a href="http://beta.frikanalen.no/video/625090/">EFF founder John Barlow</a>,
+<a href="http://beta.frikanalen.no/video/625432/">how to make 3D
+printer electronics</a> and many more fascinating topics? It works
+using only free software (all of it
+<a href="http://github.com/Frikanalen">available from Github</a>), and
+is administrated using a web browser and a web API.</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

+ <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>

+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>

+git clone https://github.com/WhisperSystems/Signal-Desktop.git
</pre>
-<p>The key can be downloaded from the OpenPGP key servers, signed by
-my old key.</p>
+<p>Next, I patched the source to use the production servers, to be
+able to talk to other Signal users:</p>
+
+<pre>
+cat &lt;&lt;EOF | patch -p0

-<p>If you signed my old key
-(<a href="http://pgp.cs.uu.nl/stats/DB4CCC4B2A30D729.html">DB4CCC4B2A30D729</a>),
-I'd very much appreciate a signature on my new key, details and
-instructions in the transition statement. I m happy to reciprocate if
-you have a similarly signed transition statement to present.</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>
+#!/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 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>

+ <title>The new "best" multimedia player in Debian?</title>

+ <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>
