- <description><p>A little more than 11 years ago, one of the creators of Tor, and
-the current President of the Tor project, Roger Dingledine, gave a
-talk for the members of the Norwegian Unix User group (NUUG). A video

-video of the talk on Frikanalen, the Norwegian open channel TV station
-where NUUG currently publishes its talks. You can

+ <title>Quicker Debian installations using eatmydata</title>

+ <pubDate>Fri, 25 Nov 2016 14:50:00 +0100</pubDate>
+ <description><p>Two years ago, I did some experiments with eatmydata and the Debian
+installation system, observing how using
+<a href="http://people.skolelinux.org/pere/blog/Speeding_up_the_Debian_installer_using_eatmydata_and_dpkg_divert.html">eatmydata
+could speed up the installation</a> quite a bit. My testing measured
+speedup around 20-40 percent for Debian Edu, where we install around
+1000 packages from within the installer. The eatmydata package
+provide a way to disable/delay file system flushing. This is a bit
+risky in the general case, as files that should be stored on disk will
+stay only in memory a bit longer than expected, causing problems if a
+machine crashes at an inconvenient time. But for an installation, if
+the machine crashes during installation the process is normally
+restarted, and avoiding disk operations as much as possible to speed
+up the process make perfect sense.
+
+<p>I added code in the Debian Edu specific installation code to enable
+<a href="https://tracker.debian.org/pkg/libeatmydata">eatmydata</a>,
+but did not have time to push it any further. But a few months ago I
+picked it up again and worked with the libeatmydata package maintainer
+Mattia Rizzolo to make it easier for everyone to get this installation
+speedup in Debian. Thanks to our cooperation There is now an
+eatmydata-udeb package in Debian testing and unstable, and simply
+enabling/installing it in debian-installer (d-i) is enough to get the
+quicker installations. It can be enabled using preseeding. The
+following untested kernel argument should do the trick:</p>
+
+<blockquote><pre>
+preseed/early_command="anna-install eatmydata-udeb"
+</pre></blockquote>
+
+<p>This should ask d-i to install the package inside the d-i
+environment early in the installation sequence. Having it installed
+in d-i in turn will make sure the relevant scripts are called just
+after debootstrap filled /target/ with the freshly installed Debian
+system to configure apt to run dpkg with eatmydata. This is enough to
+speed up the installation process. There is a proposal to
+<a href="https://bugs.debian.org/841153">extend the idea a bit further
+by using /etc/ld.so.preload instead of apt.conf</a>, but I have not
+tested its impact.</p>
-<p>I guess the gist of the talk can be summarized quite simply: If you
-want to help the military in USA (and everyone else), use Tor. :)</p>

- <title>Isenkram with PackageKit support - new version 0.23 available in Debian unstable</title>

- <description><p><a href="https://tracker.debian.org/pkg/isenkram">The isenkram
-system</a> is a user-focused solution in Debian for handling hardware
-related packages. The idea is to have a database of mappings between
-hardware and packages, and pop up a dialog suggesting for the user to
-install the packages to use a given hardware dongle. Some use cases
-are when you insert a Yubikey, it proposes to install the software
-needed to control it; when you insert a braille reader list it
-proposes to install the packages needed to send text to the reader;
-and when you insert a ColorHug screen calibrator it suggests to
-install the driver for it. The system work well, and even have a few
-command line tools to install firmware packages and packages for the
-hardware already in the machine (as opposed to hotpluggable hardware).</p>
-
-<p>The system was initially written using aptdaemon, because I found
-good documentation and example code on how to use it. But aptdaemon
-is going away and is generally being replaced by
-<a href="http://www.freedesktop.org/software/PackageKit/">PackageKit</a>,
-so Isenkram needed a rewrite. And today, thanks to the great patch
-from my college Sunil Mohan Adapa in the FreedomBox project, the
-rewrite finally took place. I've just uploaded a new version of
-Isenkram into Debian Unstable with the patch included, and the default
-for the background daemon is now to use PackageKit. To check it out,
-install the <tt>isenkram</tt> package and insert some hardware dongle
-and see if it is recognised.</p>
-
-<p>If you want to know what kind of packages isenkram would propose for
-the machine it is running on, you can check out the isenkram-lookup
-program. This is what it look like on a Thinkpad X230:</p>
-
-<p><blockquote><pre>
-% isenkram-lookup
-bluez
-cheese
-fprintd
-fprintd-demo
-gkrellm-thinkbat
-hdapsd
-libpam-fprintd
-pidgin-blinklight
-thinkfan
-tleds
-tp-smapi-dkms
-tp-smapi-source
-tpb
-%p
-</pre></blockquote></p>
-
-<p>The hardware mappings come from several places. The preferred way
-is for packages to announce their hardware support using
-<a href="https://www.freedesktop.org/software/appstream/docs/">the
-cross distribution appstream system</a>.
-See
-<a href="http://people.skolelinux.org/pere/blog/tags/isenkram/">previous
-blog posts about isenkram</a> to learn how to do that.</p>

- <title>Discharge rate estimate in new battery statistics collector for Debian</title>
- <link>http://people.skolelinux.org/pere/blog/Discharge_rate_estimate_in_new_battery_statistics_collector_for_Debian.html</link>
- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Discharge_rate_estimate_in_new_battery_statistics_collector_for_Debian.html</guid>
- <pubDate>Mon, 23 May 2016 09:35:00 +0200</pubDate>
- <description><p>Yesterday I updated the
-<a href="https://tracker.debian.org/pkg/battery-stats">battery-stats
-package in Debian</a> with a few patches sent to me by skilled and
-enterprising users. There were some nice user and visible changes.
-First of all, both desktop menu entries now work. A design flaw in
-one of the script made the history graph fail to show up (its PNG was
-dumped in ~/.xsession-errors) if no controlling TTY was available.
-The script worked when called from the command line, but not when
-called from the desktop menu. I changed this to look for a DISPLAY
-variable or a TTY before deciding where to draw the graph, and now the
-graph window pop up as expected.</p>
-
-<p>The next new feature is a discharge rate estimator in one of the
-graphs (the one showing the last few hours). New is also the user of
-colours showing charging in blue and discharge in red. The percentages
-of this graph is relative to last full charge, not battery design
-capacity.</p>
-
-<p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2016-05-23-battery-stats-rate.png"/></p>
-
-<p>The other graph show the entire history of the collected battery
-statistics, comparing it to the design capacity of the battery to
-visualise how the battery life time get shorter over time. The red
-line in this graph is what the previous graph considers 100 percent:
-
-<p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2016-05-23-battery-stats-history.png"/></p>
-
-<p>In this graph you can see that I only charge the battery to 80
-percent of last full capacity, and how the capacity of the battery is
-shrinking. :(</p>
-
-<p>The last new feature is in the collector, which now will handle
-more hardware models. On some hardware, Linux power supply
-information is stored in /sys/class/power_supply/ACAD/, while the
-collector previously only looked in /sys/class/power_supply/AC/. Now
-both are checked to figure if there is power connected to the
-machine.</p>
-
-<p>If you are interested in how your laptop battery is doing, please
-check out the
-<a href="https://tracker.debian.org/pkg/battery-stats">battery-stats</a>
-in Debian unstable, or rebuild it on Jessie to get it working on
-Debian stable. :) The upstream source is available from <a
-href="https://github.com/petterreinholdtsen/battery-stats">github</a>.
-Patches are very welcome.</p>

-activities, please send Bitcoin donations to my address

+ <description><p>For noen dager siden ble jeg tipset av min venn Andreas
+Aanerud om at <a href="http://magasinetpegasus.no">magasinet
+Pegasus</a> skulle ta i bruk
+<a href="https://creativecommons.org/">Creative
+Commons</a>-lisensiering på sine artikler. Han fortalte at den
+direkte årsaken var at han hadde blitt inspirert av å lese
+<a href=" http://www.lulu.com/shop/http://www.lulu.com/shop/lawrence-lessig/fri-kultur/paperback/product-22441576.html">boken
+Fri kultur</a>
+(<a href="https://github.com/petterreinholdtsen/free-culture-lessig">github</a>)
+og foreslått endringen. Jeg ble veldig glad for å høre
+dette, da det er det første konkrete tilfellet jeg har hørt om der den
+norske oversettelsen av <a href="http://www.free-culture.cc/">
+Lawrence Lessigs bok Free Culture</a> som jeg ga ut i fjor høst hadde
+fått noen til å ta i bruk Creative Commons.</p>
+
+<p>Andreas fikk boken av meg som takk for at han inviterte meg til
+<a href="http://www.gathering.org/">The Gathering</a>, og jeg er veldig
+glad for at den falt i smak. Jeg ble nysgjerrig på hva som var
+bakgrunnen for denne policy-endringen hos Hyperion og han sa seg
+villig til å la seg intervjue til bloggen min. </p>
+
+<blockquote>
+
+<p><strong>Hvilke tanker gjorde du deg da boken lå i hånden første
+gang?</strong></p>
+
+<p>Jeg husker da jeg fikk boken, etter en omvisning på The Gathering i
+2016, der jeg var Core Organizer. The Gathering er jo et sted hvor en
+fremmer delingskultur, i alt fra kode, til løsninger og «hacks», så en
+kan vel si at boken er veldig relevant!</p>
+
+<p>Mine første tanker om boken, var at den trengte et grafisk løft.
+Selv har jeg dysleksi og er ikke verdens beste i å lese, men for meg
+så skal ikke det bety at jeg ikke klarer å lese. Jeg har jo også mine
+egne tanker om «Fri kultur», ettersom jeg har jobbet med noen norske
+filmer via NRK og TV2 og nå sitter som en teknisk leder i
+filmavdelingen til Schjærven Reklamebyrå.</p>
+
+<p><strong>Har du lest boken, og hva tenker du om den nå?</strong></p>
+
+<p>Jeg har lest boken, og for meg er det jo veldig moro å kunne si at
+Disney var en pirat og nå ha bevisene. Men det å gå fra Disney via
+RIAA, og så igjennom en jungel av teknikk og programmering og ende opp
+med spørsmålet om vi alle piratkopierer litt, er enda bedre. For ja,
+boken klarer å få frem en diskusjon om åndsverk på en god måte
+gjennom en samling historier, men den viste meg også et bilde, hvor
+teknologi blir kneblet, og ikke får lov til å utvikle seg, ettersom
+«opphavsrettsinnehaverne» bryr seg mer om sin industri enn om verden
+går fremover. Ta f.eks. internettradio! Hvorfor tuller vi med DAB+
+og alt det der, når radio kan være en app på alle telefoner i dag.
+Men den største tanken som jeg satt igjen med, er at vi må få færre
+advokater og flere tenkere som kan dra oss vekk fra de feilene vi er i
+ferd med å ende opp i.</p>
+
+<p><strong>Har budskapet i boken påvirker deg og det du holder på
+med?</strong></p>
+
+<p>The Gathering sin moderforening er
+<a href="http://www.kandu.no/">KANDU</a>, som er et stolt medlem av <a
+href="http://n4f.no/">Hyperion</a>. Hyperion har et mandat igjennom
+sitt interne magasin Pegasus å fremme Hyperion sine
+medlemsarrangementer og kultur. Dette tror jeg er veldig viktig, og en
+av de viktigste virkemidlene det magasinet nå har fått, er pålegget om
+å publisere alt under de forskjellige Creative Commons
+retningslinjer. Grunnen til at Pegasus kan velge fritt blant lisensene
+til Creative Commons er deres bruk av freelancere m.m. som også må få
+sine rettigheter dekket.</p>
+
+<p>Det er et steg i riktig retning som jeg håper, vil gi lokalaviser,
+nasjonale aviser, bloggere m.m. muligheten til å referere til Pegasus
+sitt innhold uten å måtte be om tillatelse først, som i bunnen vil
+hjelpe oss å spre vår kultur i Hyperion.</p>
+
+<p><strong>Hva fikk Pegasus til å vedta retninglinjer om bruk av
+Creative Commons, og hvordan kom dere frem til en slik
+policy?</strong></p>
+
+<p>Dette skjedde på Hyperion sitt landsting, hvor jeg ønsket å fremme
+Creative Commons som en retning som flere mener magasinet burde ta,
+hvordan Pegasus tar det i bruk er mer opp til redaksjonen. Det som var
+trist er at en del har misforstått hva Creative Commons er. Vi fikk
+en veldig het «debatt» på facebook i etterkant hvor noen blant annet
+mener at dette vedtaket har drept Pegasus.</p>
+
+<p>Personlig syntes jeg disse reaksjonene er rare, ettersom Pegasus er
+et medlemsmagasin og magasinet sitt mål er å spre vår fantastiske
+kultur. Jeg mener at Ceative Commons-bruksvilkår på artikler skaper
+en veldig god mulighet til å spre denne kulturen. Det gjør at større
+og mindre aviser kan låne artikler fra medlemsmagasinet og publisere
+det hos seg, slik at effekten nettopp er fremme vår kultur.</p>
+
+<p>Jeg gleder meg til å se hvordan redaksjonen håndhever bruken av
+Creative Commons.</p>
+
+<p><strong>Hvem tror du kunne ha mest nytte av å lese Fri
+kultur?</strong></p>
+
+<p>Jeg tror at boken Fri kultur bør leses av de som ønsker en debatt
+om nye medier, samt de som jobber med medier og føler seg «truet» av
+utviklingen. Kanskje det kan være et lysglimt om at vi må heller være
+med å utvikle oss, enn å stoppe opp og «beskytte» våre eier-, penge-
+og materielle interesser.</p>
+
+<p>Spørsmålet for redaksjoner vil vel være om de «tjener» på klikk og
+sine artikler via annonser, i så fall ville jeg tenkt litt rundt
+spredningen. Nettavisen Digi.no gjorde en analyse i 2015 som var
+veldig fin. Hvor de måtte konkludere med at de fikk ut budskapet
+bedre, men de mistet inntekter på annonsevisning.</p>
+
+<p>Derfor for et magasin som skal «spre» kultur, så burde Creative
+Commons være en no-brainer, en kunne også kanskje argumentere med at
+NRK også burde gjøre dette, ettersom de ikke lever av reklame, og vi
+betaler for innholdet deres.</p>
+
+<p><strong>Kommer du til å anbefale boken til noen du
+kjenner?</strong></p>
+
+<p>Absolutt! Jeg har faktisk tenkt å gi den videre som en vandrebok,
+til redaksjonen i Pegasus slik at de kan lese den og få noen ider og
+tanker om fri kultur.</p>
+
+<p><strong>Du sier at boken klarer å få frem viktig en diskusjon om
+ vern av åndsverk. Boken er jo skrevet med bakgrunn i USAs
+ Copyright-lovgiving og ikke den norske åndsverksloven. Hva gjør at
+ du mener boken er relevant for den norske debatten?</strong></p>
+
+<p>En av tingene boken pekte på var tanken om hvor opphavsretten skal
+ligge. Skal den ligge hos den som skriver sangen, den som fremfører
+eller den som tar opp sangen. Og når spørsmålet kom tilbake i en
+software-utgave, «hvordan kan Adobe styre opphavsretten i sin eBook
+Publisher» så føler jeg at vi kommer inn på spennende tanker som jeg
+mener vi glemmer i norsk åndsverksdebatt. USA har rett å slett et
+«større bilde» som kanskje vi kan ta lærdom av.</p>
+
+</blockquote>
+
+<p>Jeg er veldig spent på hvordan redaksjonen i Pegasus kommer til å
+ta i bruk Creative Commons, og gleder meg til neste tegn på at
+bokutgivelsen har fått noen til å tenke mer på problemene med dagens
+åndsverksvern.</p>

- <description><p>I just donated to the
-<a href="http://www.nuug.no/dns-beslag-donasjon.shtml">NUUG defence
-"fond"</a> to fund the effort in Norway to get the seizure of the news
-site popcorn-time.no tested in court. I hope everyone that agree with
-me will do the same.</p>
-
-<p>Would you be worried if you knew the police in your country could
-hijack DNS domains of news sites covering free software system without
-talking to a judge first? I am. What if the free software system
-combined search engine lookups, bittorrent downloads and video playout
-and was called Popcorn Time? Would that affect your view? It still
-make me worried.</p>
-
-<p>In March 2016, the Norwegian police seized (as in forced NORID to
-change the IP address pointed to by it to one controlled by the
-police) the DNS domain popcorn-time.no, without any supervision from
-the courts. I did not know about the web site back then, and assumed
-the courts had been involved, and was very surprised when I discovered
-that the police had hijacked the DNS domain without asking a judge for
-permission first. I was even more surprised when I had a look at
-<a href="https://web.archive.org/web/*/http://popcorn-time.no">the web
-site content on the Internet Archive</A>, and only found news coverage
-about Popcorn Time, not any material published without the right
-holders permissions.</p>
-
-<p>The seizure was widely covered in the Norwegian press (see for
-example <a href="http://www.hegnar.no/Nyheter/Naeringsliv/2016/03/Popcorn-time.no-beslaglagt-av-OEkokrim">Hegnar Online</a> and
-<a href="http://itavisen.no/2016/03/08/okokrim-har-beslaglagt-popcorn-time-no/">ITavisen<a/>
-and
-<a href="http://www.nrk.no/kultur/okokrim-gar-til-aksjon-mot-popcorn-time-1.12842452">NRK</a>),
-at first due to the press release sent out by Økokrim, but then based
-on
-<a href="http://blogg.torvund.net/2016/03/09/okokrims-beslag-i-domenet-popcorn-time-no/">protests
-from the law professor Olav Torvund</a> and
-<a href="http://www.klassekampen.no/article/20160311/ARTICLE/160319995">lawyer
-Jon Wessel-Aas</a>. It even got some
-<a href="https://torrentfreak.com/norwegian-authorities-sued-over-popcorn-time-domain-seizure-160418/">coverage
-on TorrentFreak</a>.</p>
-
-<p>I
-<a href="http://people.skolelinux.org/pere/blog/NUUG_contests_Norwegian_police_DNS_seizure_of_popcorn_time_no.html">
-wrote about the case a month ago</a>, when the
-<a href="http://www.nuug.no/">Norwegian Unix User Group</a> (NUUG),
-where I am an active member, decided to ask the courts to test this seizure.
-The request was denied, but NUUG and its co-requestor EFN have not
-given up, and now they are rallying for support to get the seizure
-legally challenged. They accept both bank and Bitcoin transfer for
-those that want to support the request.</p>
-
-<p>If you as me believe news sites about free software should not be
-censored, even if the free software have both legal and illegal
-applications, and that DNS hijacking should be tested by the courts, I
-suggest you <a href="http://www.nuug.no/dns-beslag-donasjon.shtml">show
-your support by donating to NUUG</a>.</a>

+ <description><p>A few days ago I ran a very biased and informal survey to get an
+idea about what options are being used to communicate with end to end
+encryption with friends and family. I explicitly asked people not to
+list options only used in a work setting. The background is the
+uneasy feeling I get when using Signal, a feeling shared by others as
+a blog post from Sander Venima about
+<a href="https://sandervenema.ch/2016/11/why-i-wont-recommend-signal-anymore/">why
+he do not recommend Signal anymore</a> (with
+<a href="https://news.ycombinator.com/item?id=12883410">feedback from
+the Signal author available from ycombinator</a>). I wanted an
+overview of the options being used, and hope to include those options
+in a less biased survey later on. So far I have not taken the time to
+look into the individual proposed systems. They range from text
+sharing web pages, via file sharing and email to instant messaging,
+VOIP and video conferencing. For those considering which system to
+use, it is also useful to have a look at
+<a href="https://www.eff.org/secure-messaging-scorecard">the EFF Secure
+messaging scorecard</a> which is slightly out of date but still
+provide valuable information.</p>
+
+<p>So, on to the list. There were some used by many, some used by a
+few, some rarely used ones and a few mentioned but without anyone
+claiming to use them. Notice the grouping is in reality quite random
+given the biased self selected set of participants. First the ones
+used by many:</p>
+
+<ul>
+
+<li><a href="https://whispersystems.org/">Signal</a></li>
+<li>Email w/<a href="http://openpgp.org/">OpenPGP</a> (Enigmail, GPGSuite,etc)</li>
+<li><a href="https://www.whatsapp.com/">Whatsapp</a></li>
+<li>IRC w/<a href="https://otr.cypherpunks.ca/">OTR</a></li>
+<li>XMPP w/<a href="https://otr.cypherpunks.ca/">OTR</a></li>
+
+</ul>
+
+<p>Then the ones used by a few.</p>
+
+<ul>
+
+<li><a href="https://wiki.mumble.info/wiki/Main_Page">Mumble</a></li>
+<li>iMessage (included in iOS from Apple)</li>
+<li><a href="https://telegram.org/">Telegram</a></li>
+<li><a href="https://jitsi.org/">Jitsi</a></li>
+<li><a href="https://keybase.io/download">Keybase file</a></li>
+
+</ul>
+
+<p>Then the ones used by even fewer people</p>
+
+<ul>
+
+<li><a href="https://ring.cx/">Ring</a></li>
+<li><a href="https://bitmessage.org/">Bitmessage</a></li>
+<li><a href="https://wire.com/">Wire</a></li>
+<li>VoIP w/<a href="https://en.wikipedia.org/wiki/ZRTP">ZRTP</a> or controlled <a href="https://en.wikipedia.org/wiki/Secure_Real-time_Transport_Protocol">SRTP</a> (e.g using <a href="https://en.wikipedia.org/wiki/CSipSimple">CSipSimple</a>, <a href="https://en.wikipedia.org/wiki/Linphone">Linphone</a>)</li>
+<li><a href="https://matrix.org/">Matrix</a></li>
+<li><a href="https://kontalk.org/">Kontalk</a></li>
+<li><a href="https://0bin.net/">0bin</a> (encrypted pastebin)</li>

+<li><a href="https://riot.im/">riot</a></li>
+<li><a href="https://www.wickr.com/">Wickr Me</a></li>
+
+</ul>
+
+<p>And finally the ones mentioned by not marked as used by
+anyone. This might be a mistake, perhaps the person adding the entry
+forgot to flag it as used?</p>
+
+<ul>
+
+<li>Email w/Certificates <a href="https://en.wikipedia.org/wiki/S/MIME">S/MIME</a></li>
+<li><a href="https://www.crypho.com/">Crypho</a></li>
+<li><a href="https://cryptpad.fr/">CryptPad</a></li>
+<li><a href="https://github.com/ricochet-im/ricochet">ricochet</a></li>
+
+</ul>
+
+<p>Given the network effect it seem obvious to me that we as a society
+have been divided and conquered by those interested in keeping
+encrypted and secure communication away from the masses. The
+finishing remarks <a href="https://vimeo.com/97505679">from Aral Balkan
+in his talk "Free is a lie"</a> about the usability of free software
+really come into effect when you want to communicate in private with
+your friends and family. We can not expect them to allow the
+usability of communication tool to block their ability to talk to
+their loved ones.</p>
+
+<p>Note for example the option IRC w/OTR. Most IRC clients do not
+have OTR support, so in most cases OTR would not be an option, even if
+you wanted to. In my personal experience, about 1 in 20 I talk to
+have a IRC client with OTR. For private communication to really be
+available, most people to talk to must have the option in their
+currently used client. I can not simply ask my family to install an
+IRC client. I need to guide them through a technical multi-step
+process of adding extensions to the client to get them going. This is
+a non-starter for most.</p>
+
+<p>I would like to be able to do video phone calls, audio phone calls,
+exchange instant messages and share files with my loved ones, without
+being forced to share with people I do not know. I do not want to
+share the content of the conversations, and I do not want to share who
+I communicate with or the fact that I communicate with someone.
+Without all these factors in place, my private life is being more or
+less invaded.</p>

+ <description><p>A while back I received a Gyro sensor for the NXT
+<a href="mindstorms.lego.com">Mindstorms</a> controller as a birthday
+present. It had been on my wishlist for a while, because I wanted to
+build a Segway like balancing lego robot. I had already built
+<a href="http://www.nxtprograms.com/NXT2/segway/">a simple balancing
+robot</a> with the kids, using the light/color sensor included in the
+NXT kit as the balance sensor, but it was not working very well. It
+could balance for a while, but was very sensitive to the light
+condition in the room and the reflective properties of the surface and
+would fall over after a short while. I wanted something more robust,
+and had
+<a href="https://www.hitechnic.com/cgi-bin/commerce.cgi?preadd=action&key=NGY1044">the
+gyro sensor from HiTechnic</a> I believed would solve it on my
+wishlist for some years before it suddenly showed up as a gift from my
+loved ones. :)</p>
+
+<p>Unfortunately I have not had time to sit down and play with it
+since then. But that changed some days ago, when I was searching for
+lego segway information and came across a recipe from HiTechnic for
+building
+<a href="http://www.hitechnic.com/blog/gyro-sensor/htway/">the
+HTWay</a>, a segway like balancing robot. Build instructions and
+<a href="https://www.hitechnic.com/upload/786-HTWayC.nxc">source
+code</a> was included, so it was just a question of putting it all
+together. And thanks to the great work of many Debian developers, the
+compiler needed to build the source for the NXT is already included in
+Debian, so I was read to go in less than an hour. The resulting robot
+do not look very impressive in its simplicity:</p>
+
+<p align="center"><img width="70%" src="http://people.skolelinux.org/pere/blog/images/2016-11-04-lego-htway-robot.jpeg"></p>
+
+<p>Because I lack the infrared sensor used to control the robot in the
+design from HiTechnic, I had to comment out the last task
+(taskControl). I simply placed /* and */ around it get the program
+working without that sensor present. Now it balances just fine until
+the battery status run low:</p>
+
+<p align="center"><video width="70%" controls="true">
+ <source src="http://people.skolelinux.org/pere/blog/images/2016-11-04-lego-htway-balancing.ogv" type="video/ogg">
+</video></p>
+
+<p>Now we would like to teach it how to follow a line and take remote
+control instructions using the included Bluetooth receiver in the NXT.</p>
+
+<p>If you, like me, love LEGO and want to make sure we find the tools
+they need to work with LEGO in Debian and all our derivative
+distributions like Ubuntu, check out
+<a href="http://wiki.debian.org/LegoDesigners">the LEGO designers
+project page</a> and join the Debian LEGO team. Personally I own a
+RCX and NXT controller (no EV3), and would like to make sure the
+Debian tools needed to program the systems I own work as they
+should.</p>

- <title>What is the best multimedia player in Debian?</title>

- <description><p><strong>Where I set out to figure out which multimedia player in
-Debian claim support for most file formats.</strong></p>
-
-<p>A few years ago, I had a look at the media support for Browser
-plugins in Debian, to get an idea which plugins to include in Debian
-Edu. I created a script to extract the set of supported MIME types
-for each plugin, and used this to find out which multimedia browser
-plugin supported most file formats / media types.
-<a href="https://wiki.debian.org/DebianEdu/BrowserMultimedia">The
-result</a> can still be seen on the Debian wiki, even though it have
-not been updated for a while. But browser plugins are less relevant
-these days, so I thought it was time to look at standalone
-players.</p>
-
-<p>A few days ago I was tired of VLC not being listed as a viable
-player when I wanted to play videos from the Norwegian National
-Broadcasting Company, and decided to investigate why. The cause is a
-<a href="https://bugs.debian.org/822245">missing MIME type in the VLC
-desktop file</a>. In the process I wrote a script to compare the set
-of MIME types announced in the desktop file and the browser plugin,
-only to discover that there is quite a large difference between the
-two for VLC. This discovery made me dig up the script I used to
-compare browser plugins, and adjust it to compare desktop files
-instead, to try to figure out which multimedia player in Debian
-support most file formats.</p>
-
-<p>The result can be seen on the Debian Wiki, as
-<a href="https://wiki.debian.org/DebianMultimedia/PlayerSupport">a
-table listing all MIME types supported by one of the packages included
-in the table</a>, with the package supporting most MIME types being
-listed first in the table.</p>
-
-</p>The best multimedia player in Debian? It is totem, followed by
-parole, kplayer, mpv, vlc, smplayer mplayer-gui gnome-mpv and
-kmplayer. Time for the other players to update their announced MIME
-support?</p>

+ <description><p>Jeg ble så imponert over
+<a href="https://www.nrk.no/norge/forbrukerradet-mener-aktivitetsarmband-strider-mot-norsk-lov-1.13209079">dagens
+gladnyhet på NRK</a>, om at Forbrukerrådet klager inn vilkårene for
+bruk av aktivitetsbånd fra Fitbit, Garmin, Jawbone og Mio til
+Datatilsynet og forbrukerombudet, at jeg sendte følgende brev til
+forbrukerrådet for å uttrykke min støtte:
+
+<blockquote>
+
+<p>Jeg ble veldig glad over å lese at Forbrukerrådet
+<a href="http://www.forbrukerradet.no/siste-nytt/klager-inn-aktivitetsarmband-for-brudd-pa-norsk-lov/">klager
+inn flere aktivitetsbånd til Datatilsynet for dårlige vilkår</a>. Jeg
+har ønsket meg et aktivitetsbånd som kan måle puls, bevegelse og
+gjerne også andre helserelaterte indikatorer en stund nå. De eneste
+jeg har funnet i salg gjør, som dere også har oppdaget, graverende
+inngrep i privatsfæren og sender informasjonen ut av huset til folk og
+organisasjoner jeg ikke ønsker å dele aktivitets- og helseinformasjon
+med. Jeg ønsker et alternativ som <em>ikke</em> sender informasjon til
+skyen, men derimot bruker
+<a href="http://people.skolelinux.org/pere/blog/Fri_og__pen_standard__slik_Digistan_ser_det.html">en
+fritt og åpent standardisert</a> protokoll (eller i det minste en
+dokumentert protokoll uten patent- og opphavsrettslige
+bruksbegrensinger) til å kommunisere med datautstyr jeg kontrollerer.
+Er jo ikke interessert i å betale noen for å tilrøve seg
+personopplysninger fra meg. Desverre har jeg ikke funnet noe
+alternativ så langt.</p>
+
+<p>Det holder ikke å endre på bruksvilkårene for enhetene, slik
+Datatilsynet ofte legger opp til i sin behandling, når de gjør slik
+f.eks. Fitbit (den jeg har sett mest på). Fitbit krypterer
+informasjonen på enheten og sender den kryptert til leverandøren. Det
+gjør det i praksis umulig både å sjekke hva slags informasjon som
+sendes over, og umulig å ta imot informasjonen selv i stedet for
+Fitbit. Uansett hva slags historie som forteller i bruksvilkårene er
+en jo både prisgitt leverandørens godvilje og at de ikke tvinges av
+sitt lands myndigheter til å lyve til sine kunder om hvorvidt
+personopplysninger spres ut over det bruksvilkårene sier. Det er
+veldokumentert hvordan f.eks. USA tvinger selskaper vha. såkalte
+National security letters til å utlevere personopplysninger samtidig
+som de ikke får lov til å fortelle dette til kundene sine.</p>
+
+<p>Stå på, jeg er veldig glade for at dere har sett på saken. Vet
+dere om aktivitetsbånd i salg i dag som ikke tvinger en til å utlevere
+aktivitets- og helseopplysninger med leverandøren?</p>
+
+</blockquote>
+
+<p>Jeg håper en konkurrent som respekterer kundenes privatliv klarer å
+nå opp i markedet, slik at det finnes et reelt alternativ for oss som
+har full tillit til at skyleverandører vil prioritere egen inntjening
+og myndighetspålegg langt foran kundenes rett til privatliv. Jeg har
+ingen tiltro til at Datatilsynet vil kreve noe mer enn at vilkårene
+endres slik at de forklarer eksplisitt i hvor stor grad bruk av
+produktene utraderer privatsfæren til kundene. Det vil nok gjøre de
+innklagede armbåndene «lovlige», men fortsatt tvinge kundene til å
+dele sine personopplysninger med leverandøren.</p>

+ <pubDate>Mon, 10 Oct 2016 11:30:00 +0200</pubDate>
+ <description><p>In July
+<a href="http://people.skolelinux.org/pere/blog/How_to_use_the_Signal_app_if_you_only_have_a_land_line__ie_no_mobile_phone_.html">I
+wrote how to get the Signal Chrome/Chromium app working</a> without
+the ability to receive SMS messages (aka without a cell phone). It is
+time to share some experiences and provide an updated setup.</p>
+
+<p>The Signal app have worked fine for several months now, and I use
+it regularly to chat with my loved ones. I had a major snag at the
+end of my summer vacation, when the the app completely forgot my
+setup, identity and keys. The reason behind this major mess was
+running out of disk space. To avoid that ever happening again I have
+started storing everything in <tt>userdata/</tt> in git, to be able to
+roll back to an earlier version if the files are wiped by mistake. I
+had to use it once after introducing the git backup. When rolling
+back to an earlier version, one need to use the 'reset session' option
+in Signal to get going, and notify the people you talk with about the
+problem. I assume there is some sequence number tracking in the
+protocol to detect rollback attacks. The git repository is rather big
+(674 MiB so far), but I have not tried to figure out if some of the
+content can be added to a .gitignore file due to lack of spare
+time.</p>
+
+<p>I've also hit the 90 days timeout blocking, and noticed that this
+make it impossible to send messages using Signal. I could still
+receive them, but had to patch the code with a new timestamp to send.
+I believe the timeout is added by the developers to force people to
+upgrade to the latest version of the app, even when there is no
+protocol changes, to reduce the version skew among the user base and
+thus try to keep the number of support requests down.</p>
+
+<p>Since my original recipe, the Signal source code changed slightly,
+making the old patch fail to apply cleanly. Below is an updated
+patch, including the shell wrapper I use to start Signal. The
+original version required a new user to locate the JavaScript console
+and call a function from there. I got help from a friend with more
+JavaScript knowledge than me to modify the code to provide a GUI
+button instead. This mean that to get started you just need to run
+the wrapper and click the 'Register without mobile phone' to get going
+now. I've also modified the timeout code to always set it to 90 days
+in the future, to avoid having to patch the code regularly.</p>
+
+<p>So, the updated recipe for Debian Jessie:</p>
+
+<ol>
+
+<li>First, install required packages to get the source code and the
+browser you need. Signal only work with Chrome/Chromium, as far as I
+know, so you need to install it.
+
+<pre>
+apt install git tor chromium
+git clone https://github.com/WhisperSystems/Signal-Desktop.git

+
+<li>Modify the source code using command listed in the the patch
+block below.</li>
+
+<li>Start Signal using the run-signal-app wrapper (for example using
+<tt>`pwd`/run-signal-app</tt>).
+
+<li>Click on the 'Register without mobile phone', will in a phone
+number you can receive calls to the next minute, receive the
+verification code and enter it into the form field and press
+'Register'. Note, the phone number you use will be user Signal
+username, ie the way others can find you on Signal.</li>
+
+<li>You can now use Signal to contact others. Note, new contacts do
+not show up in the contact list until you restart Signal, and there is
+no way to assign names to Contacts. There is also no way to create or
+update chat groups. I suspect this is because the web app do not have
+a associated contact database.</li>
+
+</ol>
+
+<p>I am still a bit uneasy about using Signal, because of the way its
+main author moxie0 reject federation and accept dependencies to major
+corporations like Google (part of the code is fetched from Google) and
+Amazon (the central coordination point is owned by Amazon). See for
+example
+<a href="https://github.com/LibreSignal/LibreSignal/issues/37">the
+LibreSignal issue tracker</a> for a thread documenting the authors
+view on these issues. But the network effect is strong in this case,
+and several of the people I want to communicate with already use
+Signal. Perhaps we can all move to <a href="https://ring.cx/">Ring</a>
+once it <a href="https://bugs.debian.org/830265">work on my
+laptop</a>? It already work on Windows and Android, and is included
+in <a href="https://tracker.debian.org/pkg/ring">Debian</a> and
+<a href="https://launchpad.net/ubuntu/+source/ring">Ubuntu</a>, but not
+working on Debian Stable.</p>
+
+<p>Anyway, this is the patch I apply to the Signal code to get it
+working. It switch to the production servers, disable to timeout,
+make registration easier and add the shell wrapper:</p>

+ <description><p>NRK
+<a href="https://nrkbeta.no/2016/09/02/securing-whistleblowers/">lanserte
+for noen uker siden</a> en ny
+<a href="https://www.nrk.no/varsle/">varslerportal som bruker
+SecureDrop til å ta imot tips</a> der det er vesentlig at ingen
+utenforstående får vite at NRK er tipset. Det er et langt steg
+fremover for NRK, og når en leser bloggposten om hva de har tenkt på
+og hvordan løsningen er satt opp virker det som om de har gjort en
+grundig jobb der. Men det er ganske mye ekstra jobb å motta tips via
+SecureDrop, så varslersiden skriver "Nyhetstips som ikke krever denne
+typen ekstra vern vil vi gjerne ha på nrk.no/03030", og 03030-siden
+foreslår i tillegg til et webskjema å bruke epost, SMS, telefon,
+personlig oppmøte og brevpost. Denne artikkelen handler disse andre
+metodene.</p>
+
+<p>Når en sender epost til en @nrk.no-adresse så vil eposten sendes ut
+av landet til datamaskiner kontrollert av Microsoft. En kan sjekke
+dette selv ved å slå opp epostleveringsadresse (MX) i DNS. For NRK er
+dette i dag "nrk-no.mail.protection.outlook.com". NRK har som en ser
+valgt å sette bort epostmottaket sitt til de som står bak outlook.com,
+dvs. Microsoft. En kan sjekke hvor nettverkstrafikken tar veien
+gjennom Internett til epostmottaket vha. programmet
+<tt>traceroute</tt>, og finne ut hvem som eier en Internett-adresse
+vha. whois-systemet. Når en gjør dette for epost-trafikk til @nrk.no
+ser en at trafikken fra Norge mot nrk-no.mail.protection.outlook.com
+går via Sverige mot enten Irland eller Tyskland (det varierer fra gang
+til gang og kan endre seg over tid).</p>
+
+<p>Vi vet fra
+<a href="https://no.wikipedia.org/wiki/FRA-loven">introduksjonen av
+FRA-loven</a> at IP-trafikk som passerer grensen til Sverige avlyttes
+av Försvarets radioanstalt (FRA). Vi vet videre takket være
+Snowden-bekreftelsene at trafikk som passerer grensen til
+Storbritannia avlyttes av Government Communications Headquarters
+(GCHQ). I tillegg er er det nettopp lansert et forslag i Norge om at
+forsvarets E-tjeneste skal få avlytte trafikk som krysser grensen til
+Norge. Jeg er ikke kjent med dokumentasjon på at Irland og Tyskland
+gjør det samme. Poenget er uansett at utenlandsk etterretning har
+mulighet til å snappe opp trafikken når en sender epost til @nrk.no.
+I tillegg er det selvsagt tilgjengelig for Microsoft som er underlagt USAs
+jurisdiksjon og
+<a href="https://www.theguardian.com/world/2013/jul/11/microsoft-nsa-collaboration-user-data">samarbeider
+med USAs etterretning på flere områder</a>. De som tipser NRK om
+nyheter via epost kan dermed gå ut fra at det blir kjent for mange
+andre enn NRK at det er gjort.</p>
+
+<p>Bruk av SMS og telefon registreres av blant annet telefonselskapene
+og er tilgjengelig i følge lov og forskrift for blant annet Politi,
+NAV og Finanstilsynet, i tillegg til IT-folkene hos telefonselskapene
+og deres overordnede. Hvis innringer eller mottaker bruker
+smarttelefon vil slik kontakt også gjøres tilgjengelig for ulike
+app-leverandører og de som lytter på trafikken mellom telefon og
+app-leverandør, alt etter hva som er installert på telefonene som
+brukes.</p>
+
+<p>Brevpost kan virke trygt, og jeg vet ikke hvor mye som registreres
+og lagres av postens datastyrte postsorteringssentraler. Det vil ikke
+overraske meg om det lagres hvor i landet hver konvolutt kommer fra og
+hvor den er adressert, i hvert fall for en kortere periode. Jeg vet
+heller ikke hvem slik informasjon gjøres tilgjengelig for. Det kan
+være nok til å ringe inn potensielle kilder når det krysses med hvem
+som kjente til aktuell informasjon og hvor de befant seg (tilgjengelig
+f.eks. hvis de bærer mobiltelefon eller bor i nærheten).</p>
+
+<p>Personlig oppmøte hos en NRK-journalist er antagelig det tryggeste,
+men en bør passe seg for å bruke NRK-kantina. Der bryter de nemlig
+<a href="http://www.lovdata.no/all/hl-19850524-028.html#14">Sentralbanklovens
+paragraf 14</a> og nekter folk å betale med kontanter. I stedet
+krever de at en varsle sin bankkortutsteder om hvor en befinner seg
+ved å bruke bankkort. Banktransaksjoner er tilgjengelig for
+bankkortutsteder (det være seg VISA, Mastercard, Nets og/eller en
+bank) i tillegg til politiet og i hvert fall tidligere med Se & Hør
+(via utro tjenere, slik det ble avslørt etter utgivelsen av boken
+«Livet, det forbannede» av Ken B. Rasmussen). Men hvor mange kjenner
+en NRK-journalist personlig? Besøk på NRK på Marienlyst krever at en
+registrerer sin ankost elektronisk i besøkssystemet. Jeg vet ikke hva
+som skjer med det datasettet, men har grunn til å tro at det sendes ut
+SMS til den en skal besøke med navnet som er oppgitt. Kanskje greit å
+oppgi falskt navn.</p>
+
+<p>Når så tipset er kommet frem til NRK skal det behandles
+redaksjonelt i NRK. Der vet jeg via ulike kilder at de fleste
+journalistene bruker lokalt installert programvare, men noen bruker
+Google Docs og andre skytjenester i strid med interne retningslinjer
+når de skriver. Hvordan vet en hvem det gjelder? Ikke vet jeg, men
+det kan være greit å spørre for å sjekke at journalisten har tenkt på
+problemstillingen, før en gir et tips. Og hvis tipset omtales internt
+på epost, er det jo grunn til å tro at også intern eposten vil deles
+med Microsoft og utenlands etterretning, slik tidligere nevnt, men det
+kan hende at det holdes internt i NRKs interne MS Exchange-løsning.
+Men Microsoft ønsker å få alle Exchange-kunder over "i skyen" (eller
+andre folks datamaskiner, som det jo innebærer), så jeg vet ikke hvor
+lenge det i så fall vil vare.</p>
+
+<p>I tillegg vet en jo at
+<a href="https://www.nrk.no/ytring/elektronisk-kildevern-i-nrk-1.11941196">NRK
+har valgt å gi nasjonal sikkerhetsmyndighet (NSM) tilgang til å se på
+intern og ekstern Internett-trafikk</a> hos NRK ved oppsett av såkalte
+VDI-noder, på tross av
+<a href="https://www.nrk.no/ytring/bekymring-for-nrks-kildevern-1.11941584">protester
+fra NRKs journalistlag</a>. Jeg vet ikke om den vil kunne snappe opp
+dokumenter som lagres på interne filtjenere eller dokumenter som lages
+i de interne webbaserte publiseringssystemene, men vet at hva noden
+ser etter på nettet kontrolleres av NSM og oppdateres automatisk, slik
+at det ikke gir så mye mening å sjekke hva noden ser etter i dag når
+det kan endres automatisk i morgen.</p>
+
+<p>Personlig vet jeg ikke om jeg hadde turt tipse NRK hvis jeg satt på
+noe som kunne være en trussel mot den bestående makten i Norge eller
+verden. Til det virker det å være for mange åpninger for
+utenforstående med andre prioriteter enn NRKs journalistiske fokus.
+Og den største truslen for en varsler er jo om metainformasjon kommer
+på avveie, dvs. informasjon om at en har vært i kontakt med en
+journalist. Det kan være nok til at en kommer i myndighetenes
+søkelys, og de færreste har nok operasjonell sikkerhet til at vil tåle
+slik flombelysning på sitt privatliv.</p>

+ <description><p><a href="http://packages.qa.debian.org/isenkram">The Isenkram
+system</a> provide a practical and easy way to figure out which
+packages support the hardware in a given machine. The command line
+tool <tt>isenkram-lookup</tt> and the tasksel options provide a
+convenient way to list and install packages relevant for the current
+hardware during system installation, both user space packages and
+firmware packages. The GUI background daemon on the other hand provide
+a pop-up proposing to install packages when a new dongle is inserted
+while using the computer. For example, if you plug in a smart card
+reader, the system will ask if you want to install <tt>pcscd</tt> if
+that package isn't already installed, and if you plug in a USB video
+camera the system will ask if you want to install <tt>cheese</tt> if
+cheese is currently missing. This already work just fine.</p>
+
+<p>But Isenkram depend on a database mapping from hardware IDs to
+package names. When I started no such database existed in Debian, so
+I made my own data set and included it with the isenkram package and
+made isenkram fetch the latest version of this database from git using
+http. This way the isenkram users would get updated package proposals
+as soon as I learned more about hardware related packages.</p>
+
+<p>The hardware is identified using modalias strings. The modalias
+design is from the Linux kernel where most hardware descriptors are
+made available as a strings that can be matched using filename style
+globbing. It handle USB, PCI, DMI and a lot of other hardware related
+identifiers.</p>
+
+<p>The downside to the Isenkram specific database is that there is no
+information about relevant distribution / Debian version, making
+isenkram propose obsolete packages too. But along came AppStream, a
+cross distribution mechanism to store and collect metadata about
+software packages. When I heard about the proposal, I contacted the
+people involved and suggested to add a hardware matching rule using
+modalias strings in the specification, to be able to use AppStream for
+mapping hardware to packages. This idea was accepted and AppStream is
+now a great way for a package to announce the hardware it support in a
+distribution neutral way. I wrote
+<a href="http://people.skolelinux.org/pere/blog/Using_appstream_with_isenkram_to_install_hardware_related_packages_in_Debian.html">a
+recipe on how to add such meta-information</a> in a blog post last
+December. If you have a hardware related package in Debian, please
+announce the relevant hardware IDs using AppStream.</p>
+
+<p>In Debian, almost all packages that can talk to a LEGO Mindestorms
+RCX or NXT unit, announce this support using AppStream. The effect is
+that when you insert such LEGO robot controller into your Debian
+machine, Isenkram will propose to install the packages needed to get
+it working. The intention is that this should allow the local user to
+start programming his robot controller right away without having to
+guess what packages to use or which permissions to fix.</p>
+
+<p>But when I sat down with my son the other day to program our NXT
+unit using his Debian Stretch computer, I discovered something
+annoying. The local console user (ie my son) did not get access to
+the USB device for programming the unit. This used to work, but no
+longer in Jessie and Stretch. After some investigation and asking
+around on #debian-devel, I discovered that this was because udev had
+changed the mechanism used to grant access to local devices. The
+ConsoleKit mechanism from <tt>/lib/udev/rules.d/70-udev-acl.rules</tt>
+no longer applied, because LDAP users no longer was added to the
+plugdev group during login. Michael Biebl told me that this method
+was obsolete and the new method used ACLs instead. This was good
+news, as the plugdev mechanism is a mess when using a remote user
+directory like LDAP. Using ACLs would make sure a user lost device
+access when she logged out, even if the user left behind a background
+process which would retain the plugdev membership with the ConsoleKit
+setup. Armed with this knowledge I moved on to fix the access problem
+for the LEGO Mindstorms related packages.</p>
+
+<p>The new system uses a udev tag, 'uaccess'. It can either be
+applied directly for a device, or is applied in
+/lib/udev/rules.d/70-uaccess.rules for classes of devices. As the
+LEGO Mindstorms udev rules did not have a class, I decided to add the
+tag directly in the udev rules files included in the packages. Here
+is one example. For the nqc C compiler for the RCX, the
+<tt>/lib/udev/rules.d/60-nqc.rules</tt> file now look like this:
+
+<p><pre>
+SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="0694", ATTR{idProduct}=="0001", \
+ SYMLINK+="rcx-%k", TAG+="uaccess"
+</pre></p>
+
+<p>The key part is the 'TAG+="uaccess"' at the end. I suspect all
+packages using plugdev in their /lib/udev/rules.d/ files should be
+changed to use this tag (either directly or indirectly via
+<tt>70-uaccess.rules</tt>). Perhaps a lintian check should be created
+to detect this?</p>
+
+<p>I've been unable to find good documentation on the uaccess feature.
+It is unclear to me if the uaccess tag is an internal implementation
+detail like the udev-acl tag used by
+<tt>/lib/udev/rules.d/70-udev-acl.rules</tt>. If it is, I guess the
+indirect method is the preferred way. Michael
+<a href="https://github.com/systemd/systemd/issues/4288">asked for more
+documentation from the systemd project</a> and I hope it will make
+this clearer. For now I use the generic classes when they exist and
+is already handled by <tt>70-uaccess.rules</tt>, and add the tag
+directly if no such class exist.</p>
