-               <description>&lt;p&gt;For a while now, I have wanted to test
-&lt;a href=&quot;https://whispersystems.org/&quot;&gt;the Signal app&lt;/a&gt;, as it is
-said to provide end to end encrypted communication and several of my
-friends and family are already using it.  As I by choice do not own a
-mobile phone, this proved to be harder than expected.  And I wanted to
-have the source of the client and know that it was the code used on my
-machine.  But yesterday I managed to get it working.  I used the
-Github source, compared it to the source in
-&lt;a href=&quot;https://chrome.google.com/webstore/detail/signal-private-messenger/bikioccmkafdpakkkcpdbppfkghcmihk?hl=en-US&quot;&gt;the
-Signal Chrome app&lt;/a&gt; available from the Chrome web store, applied
-patches to use the production Signal servers, started the app and
-asked for the hidden &quot;register without a smart phone&quot; form.  Here is
-the recipe how I did it.&lt;/p&gt;

-&lt;p&gt;First, I fetched the Signal desktop source from Github, using

+               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/My_own_self_balancing_Lego_Segway.html</guid>
+                <pubDate>Fri, 4 Nov 2016 10:15:00 +0100</pubDate>
+               <description>&lt;p&gt;A while back I received a Gyro sensor for the NXT
+&lt;a href=&quot;mindstorms.lego.com&quot;&gt;Mindstorms&lt;/a&gt; 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
+&lt;a href=&quot;http://www.nxtprograms.com/NXT2/segway/&quot;&gt;a simple balancing
+robot&lt;/a&gt; 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
+&lt;a href=&quot;https://www.hitechnic.com/cgi-bin/commerce.cgi?preadd=action&amp;key=NGY1044&quot;&gt;the
+gyro sensor from HiTechnic&lt;/a&gt; I believed would solve it on my
+wishlist for some years before it suddenly showed up as a gift from my
+loved ones. :)&lt;/p&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;http://www.hitechnic.com/blog/gyro-sensor/htway/&quot;&gt;the
+HTWay&lt;/a&gt;, a segway like balancing robot.  Build instructions and
+&lt;a href=&quot;https://www.hitechnic.com/upload/786-HTWayC.nxc&quot;&gt;source
+code&lt;/a&gt; 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:&lt;/p&gt;
+
+&lt;p align=&quot;center&quot;&gt;&lt;img width=&quot;70%&quot; src=&quot;http://people.skolelinux.org/pere/blog/images/2016-11-04-lego-htway-robot.jpeg&quot;&gt;&lt;/p&gt;
+
+&lt;p&gt;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:&lt;/p&gt;
+
+&lt;p align=&quot;center&quot;&gt;&lt;video width=&quot;70%&quot; controls=&quot;true&quot;&gt;
+   &lt;source src=&quot;http://people.skolelinux.org/pere/blog/images/2016-11-04-lego-htway-balancing.ogv&quot; type=&quot;video/ogg&quot;&gt;
+&lt;/video&gt;&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;http://wiki.debian.org/LegoDesigners&quot;&gt;the LEGO designers
+project page&lt;/a&gt; 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.&lt;/p&gt;

+               <description>&lt;p&gt;Jeg ble så imponert over
+&lt;a href=&quot;https://www.nrk.no/norge/forbrukerradet-mener-aktivitetsarmband-strider-mot-norsk-lov-1.13209079&quot;&gt;dagens
+gladnyhet på NRK&lt;/a&gt;, 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:
+
+&lt;blockquote&gt;
+
+&lt;p&gt;Jeg ble veldig glad over å lese at Forbrukerrådet
+&lt;a href=&quot;http://www.forbrukerradet.no/siste-nytt/klager-inn-aktivitetsarmband-for-brudd-pa-norsk-lov/&quot;&gt;klager
+inn flere aktivitetsbånd til Datatilsynet for dårlige vilkår&lt;/a&gt;.  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 &lt;em&gt;ikke&lt;/em&gt; sender informasjon til
+skyen, men derimot bruker
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Fri_og__pen_standard__slik_Digistan_ser_det.html&quot;&gt;en
+fritt og åpent standardisert&lt;/a&gt; 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.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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?&lt;/p&gt;
+
+&lt;/blockquote&gt;
+
+&lt;p&gt;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.&lt;/p&gt;

+                <pubDate>Mon, 10 Oct 2016 11:30:00 +0200</pubDate>
+               <description>&lt;p&gt;In July
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/How_to_use_the_Signal_app_if_you_only_have_a_land_line__ie_no_mobile_phone_.html&quot;&gt;I
+wrote how to get the Signal Chrome/Chromium app working&lt;/a&gt; without
+the ability to receive SMS messages (aka without a cell phone).  It is
+time to share some experiences and provide an updated setup.&lt;/p&gt;
+
+&lt;p&gt;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 &lt;tt&gt;userdata/&lt;/tt&gt; 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 &#39;reset session&#39; 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.&lt;/p&gt;
+
+&lt;p&gt;I&#39;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.&lt;/p&gt;
+
+&lt;p&gt;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 &#39;Register without mobile phone&#39; to get going
+now.  I&#39;ve also modified the timeout code to always set it to 90 days
+in the future, to avoid having to patch the code regularly.&lt;/p&gt;
+
+&lt;p&gt;So, the updated recipe for Debian Jessie:&lt;/p&gt;
+
+&lt;ol&gt;
+
+&lt;li&gt;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.

 
 &lt;pre&gt;
 
 &lt;pre&gt;

+apt install git tor chromium

 git clone https://github.com/WhisperSystems/Signal-Desktop.git
 git clone https://github.com/WhisperSystems/Signal-Desktop.git

-&lt;/pre&gt;
-
-&lt;p&gt;Next, I patched the source to use the production servers, to be
-able to talk to other Signal users:&lt;/p&gt;
+&lt;/pre&gt;&lt;/li&gt;
+
+&lt;li&gt;Modify the source code using command listed in the the patch
+block below.&lt;/li&gt;
+
+&lt;li&gt;Start Signal using the run-signal-app wrapper (for example using
+&lt;tt&gt;`pwd`/run-signal-app&lt;/tt&gt;).
+
+&lt;li&gt;Click on the &#39;Register without mobile phone&#39;, 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
+&#39;Register&#39;.  Note, the phone number you use will be user Signal
+username, ie the way others can find you on Signal.&lt;/li&gt;
+
+&lt;li&gt;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.&lt;/li&gt;
+
+&lt;/ol&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;https://github.com/LibreSignal/LibreSignal/issues/37&quot;&gt;the
+LibreSignal issue tracker&lt;/a&gt; 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 &lt;a href=&quot;https://ring.cx/&quot;&gt;Ring&lt;/a&gt;
+once it &lt;a href=&quot;https://bugs.debian.org/830265&quot;&gt;work on my
+laptop&lt;/a&gt;?  It already work on Windows and Android, and is included
+in &lt;a href=&quot;https://tracker.debian.org/pkg/ring&quot;&gt;Debian&lt;/a&gt; and
+&lt;a href=&quot;https://launchpad.net/ubuntu/+source/ring&quot;&gt;Ubuntu&lt;/a&gt;, but not
+working on Debian Stable.&lt;/p&gt;
+
+&lt;p&gt;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:&lt;/p&gt;

-&lt;p&gt;Based on a tip and good help from the #nuug IRC channel, I wrote a
-script to launch Signal in Chromium.&lt;/p&gt;
-
-&lt;pre&gt;
-#!/bin/sh
-cd $(dirname $0)
-mkdir -p userdata
-exec chromium \
-  --proxy-server=&quot;socks://localhost:9050&quot; \
-  --user-data-dir=`pwd`/userdata --load-and-launch-app=`pwd`
-&lt;/pre&gt;
-
-&lt;p&gt; 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.&lt;/p&gt;
-
-&lt;p&gt;When the script starts, one need to follow the instructions under
-&quot;Standalone Registration&quot; 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 &#39;Console&#39; tab and wrote
-&#39;extension.install(&quot;standalone&quot;)&#39; on the console prompt to get the
-registration form.  Then I entered by land line phone number and
-pressed &#39;Call&#39;.  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.
-
-&lt;p&gt;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.&lt;/p&gt;

-               <link>http://people.skolelinux.org/pere/blog/The_new__best__multimedia_player_in_Debian_.html</link>

-                <pubDate>Mon, 6 Jun 2016 12:50:00 +0200</pubDate>
-               <description>&lt;p&gt;When I set out a few weeks ago to figure out
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/What_is_the_best_multimedia_player_in_Debian_.html&quot;&gt;which
-multimedia player in Debian claimed to support most file formats /
-MIME types&lt;/a&gt;, 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.&lt;/p&gt;
-
-&lt;p&gt;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
-&lt;a href=&quot;https://wiki.debian.org/DebianMultimedia/PlayerSupport&quot;&gt;Multimedia
-player MIME type support status&lt;/a&gt; Debian wiki page.&lt;/p&gt;
-
-&lt;p&gt;The new &quot;best&quot; 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.&lt;/p&gt;
-
-&lt;p&gt;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.&lt;/p&gt;

-               <description>&lt;p&gt;Many years ago, when koffice was fresh and with few users, I
-decided to test its presentation tool when making the slides for a
-talk I was giving for NUUG on Japhar, a free Java virtual machine.  I
-wrote the first draft of the slides, saved the result and went to bed
-the day before I would give the talk.  The next day I took a plane to
-the location where the meeting should take place, and on the plane I
-started up koffice again to polish the talk a bit, only to discover
-that kpresenter refused to load its own data file.  I cursed a bit and
-started making the slides again from memory, to have something to
-present when I arrived.  I tested that the saved files could be
-loaded, and the day seemed to be rescued.  I continued to polish the
-slides until I suddenly discovered that the saved file could no longer
-be loaded into kpresenter.  In the end I had to rewrite the slides
-three times, condensing the content until the talk became shorter and
-shorter.  After the talk I was able to pinpoint the problem &amp;ndash;
-kpresenter wrote inline images in a way itself could not understand.
-Eventually that bug was fixed and kpresenter ended up being a great
-program to make slides.  The point I&#39;m trying to make is that we
-expect a program to be able to load its own data files, and it is
-embarrassing to its developers if it can&#39;t.&lt;/p&gt;
-
-&lt;p&gt;Did you ever experience a program failing to load its own data
-files from the desktop file browser?  It is not a uncommon problem.  A
-while back I discovered that the screencast recorder
-gtk-recordmydesktop would save an Ogg Theora video file the KDE file
-browser would refuse to open.  No video player claimed to understand
-such file.  I tracked down the cause being &lt;tt&gt;file --mime-type&lt;/tt&gt;
-returning the application/ogg MIME type, which no video player I had
-installed listed as a MIME type they would understand.  I asked for
-&lt;a href=&quot;http://bugs.gw.com/view.php?id=382&quot;&gt;file to change its
-behavour&lt;/a&gt; and use the MIME type video/ogg instead.  I also asked
-several video players to add video/ogg to their desktop files, to give
-the file browser an idea what to do about Ogg Theora files.  After a
-while, the desktop file browsers in Debian started to handle the
-output from gtk-recordmydesktop properly.&lt;/p&gt;
-
-&lt;p&gt;But history repeats itself.  A few days ago I tested the music
-system Rosegarden again, and I discovered that the KDE and xfce file
-browsers did not know what to do with the Rosegarden project files
-(*.rg).  I&#39;ve reported &lt;a href=&quot;http://bugs.debian.org/825993&quot;&gt;the
-rosegarden problem to BTS&lt;/a&gt; and a fix is commited to git and will be
-included in the next upload.  To increase the chance of me remembering
-how to fix the problem next time some program fail to load its files
-from the file browser, here are some notes on how to fix it.&lt;/p&gt;
-
-&lt;p&gt;The file browsers in Debian in general operates on MIME types.
-There are two sources for the MIME type of a given file.  The output from
-&lt;tt&gt;file --mime-type&lt;/tt&gt; mentioned above, and the content of the
-shared MIME type registry (under /usr/share/mime/).  The file MIME
-type is mapped to programs supporting the MIME type, and this
-information is collected from
-&lt;a href=&quot;https://www.freedesktop.org/wiki/Specifications/desktop-entry-spec/&quot;&gt;the
-desktop files&lt;/a&gt; available in /usr/share/applications/.  If there is
-one desktop file claiming support for the MIME type of the file, it is
-activated when asking to open a given file.  If there are more, one
-can normally select which one to use by right-clicking on the file and
-selecting the wanted one using &#39;Open with&#39; or similar.  In general
-this work well.  But it depend on each program picking a good MIME
-type (preferably
-&lt;a href=&quot;http://www.iana.org/assignments/media-types/media-types.xhtml&quot;&gt;a
-MIME type registered with IANA&lt;/a&gt;), file and/or the shared MIME
-registry recognizing the file and the desktop file to list the MIME
-type in its list of supported MIME types.&lt;/p&gt;
-
-&lt;p&gt;The &lt;tt&gt;/usr/share/mime/packages/rosegarden.xml&lt;/tt&gt; entry for
-&lt;a href=&quot;http://www.freedesktop.org/wiki/Specifications/shared-mime-info-spec&quot;&gt;the
-Shared MIME database&lt;/a&gt; look like this:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
-&amp;lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&amp;gt;
-&amp;lt;mime-info xmlns=&quot;http://www.freedesktop.org/standards/shared-mime-info&quot;&amp;gt;
-  &amp;lt;mime-type type=&quot;audio/x-rosegarden&quot;&amp;gt;
-    &amp;lt;sub-class-of type=&quot;application/x-gzip&quot;/&amp;gt;
-    &amp;lt;comment&amp;gt;Rosegarden project file&amp;lt;/comment&amp;gt;
-    &amp;lt;glob pattern=&quot;*.rg&quot;/&amp;gt;
-  &amp;lt;/mime-type&amp;gt;
-&amp;lt;/mime-info&amp;gt;
-&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;This states that audio/x-rosegarden is a kind of application/x-gzip
-(it is a gzipped XML file).  Note, it is much better to use an
-official MIME type registered with IANA than it is to make up ones own
-unofficial ones like the x-rosegarden type used by rosegarden.&lt;/p&gt;
-
-&lt;p&gt;The desktop file of the rosegarden program failed to list
-audio/x-rosegarden in its list of supported MIME types, causing the
-file browsers to have no idea what to do with *.rg files:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
-% grep Mime /usr/share/applications/rosegarden.desktop
-MimeType=audio/x-rosegarden-composition;audio/x-rosegarden-device;audio/x-rosegarden-project;audio/x-rosegarden-template;audio/midi;
-X-KDE-NativeMimeType=audio/x-rosegarden-composition
-%
-&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;The fix was to add &quot;audio/x-rosegarden;&quot; at the end of the
-MimeType= line.&lt;/p&gt;
-
-&lt;p&gt;If you run into a file which fail to open the correct program when
-selected from the file browser, please check out the output from
-&lt;tt&gt;file --mime-type&lt;/tt&gt; for the file, ensure the file ending and
-MIME type is registered somewhere under /usr/share/mime/ and check
-that some desktop file under /usr/share/applications/ is claiming
-support for this MIME type.  If not, please report a bug to have it
-fixed. :)&lt;/p&gt;

+activities, please send Bitcoin donations to my address
+&lt;b&gt;&lt;a href=&quot;bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&amp;label=PetterReinholdtsenBlog&quot;&gt;15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&lt;/a&gt;&lt;/b&gt;.&lt;/p&gt;

-               <description>&lt;p&gt;A little more than 11 years ago, one of the creators of Tor, and
-the current President of &lt;a href=&quot;https://www.torproject.org/&quot;&gt;the Tor
-project&lt;/a&gt;, Roger Dingledine, gave a talk for the members of the
-&lt;a href=&quot;http://www.nuug.no/&quot;&gt;Norwegian Unix User group&lt;/a&gt; (NUUG).  A
-video of the talk was recorded, and today, thanks to the great help
-from David Noble, I finally was able to publish the video of the talk
-on Frikanalen, the Norwegian open channel TV station where NUUG
-currently publishes its talks.  You can
-&lt;a href=&quot;http://frikanalen.no/se&quot;&gt;watch the live stream using a web
-browser&lt;/a&gt; with WebM support, or check out the recording on the video
-on demand page for the talk
-&quot;&lt;a href=&quot;http://beta.frikanalen.no/video/625599&quot;&gt;Tor: Anonymous
-communication for the US Department of Defence...and you.&lt;/a&gt;&quot;.&lt;/p&gt;
-
-&lt;p&gt;Here is the video included for those of you using browsers with
-HTML video and Ogg Theora support:&lt;/p&gt;
-
-&lt;p&gt;&lt;video width=&quot;70%&quot; poster=&quot;http://simula.gunkies.org/media/625599/large_thumb/20050421-tor-frikanalen.jpg&quot; controls&gt;

-&lt;/video&gt;&lt;/p&gt;
-
-&lt;p&gt;I guess the gist of the talk can be summarised quite simply: If you
-want to help the military in USA (and everyone else), use Tor. :)&lt;/p&gt;

+               <description>&lt;p&gt;NRK
+&lt;a href=&quot;https://nrkbeta.no/2016/09/02/securing-whistleblowers/&quot;&gt;lanserte
+for noen uker siden&lt;/a&gt; en ny
+&lt;a href=&quot;https://www.nrk.no/varsle/&quot;&gt;varslerportal som bruker
+SecureDrop til å ta imot tips&lt;/a&gt; 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 &quot;Nyhetstips som ikke krever denne
+typen ekstra vern vil vi gjerne ha på nrk.no/03030&quot;, og 03030-siden
+foreslår i tillegg til et webskjema å bruke epost, SMS, telefon,
+personlig oppmøte og brevpost.  Denne artikkelen handler disse andre
+metodene.&lt;/p&gt;
+
+&lt;p&gt;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 &quot;nrk-no.mail.protection.outlook.com&quot;.  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
+&lt;tt&gt;traceroute&lt;/tt&gt;, 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).&lt;/p&gt;
+
+&lt;p&gt;Vi vet fra
+&lt;a href=&quot;https://no.wikipedia.org/wiki/FRA-loven&quot;&gt;introduksjonen av
+FRA-loven&lt;/a&gt; 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
+&lt;a href=&quot;https://www.theguardian.com/world/2013/jul/11/microsoft-nsa-collaboration-user-data&quot;&gt;samarbeider
+med USAs etterretning på flere områder&lt;/a&gt;.  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.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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).&lt;/p&gt;
+
+&lt;p&gt;Personlig oppmøte hos en NRK-journalist er antagelig det tryggeste,
+men en bør passe seg for å bruke NRK-kantina.  Der bryter de nemlig
+&lt;a href=&quot;http://www.lovdata.no/all/hl-19850524-028.html#14&quot;&gt;Sentralbanklovens
+paragraf 14&lt;/a&gt; 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 &amp; 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.&lt;/p&gt;
+
+&lt;p&gt;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 &quot;i skyen&quot; (eller
+andre folks datamaskiner, som det jo innebærer), så jeg vet ikke hvor
+lenge det i så fall vil vare.&lt;/p&gt;
+
+&lt;p&gt;I tillegg vet en jo at
+&lt;a href=&quot;https://www.nrk.no/ytring/elektronisk-kildevern-i-nrk-1.11941196&quot;&gt;NRK
+har valgt å gi nasjonal sikkerhetsmyndighet (NSM) tilgang til å se på
+intern og ekstern Internett-trafikk&lt;/a&gt; hos NRK ved oppsett av såkalte
+VDI-noder, på tross av
+&lt;a href=&quot;https://www.nrk.no/ytring/bekymring-for-nrks-kildevern-1.11941584&quot;&gt;protester
+fra NRKs journalistlag&lt;/a&gt;.  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.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;

-               <description>&lt;p&gt;&lt;a href=&quot;https://tracker.debian.org/pkg/isenkram&quot;&gt;The isenkram
-system&lt;/a&gt; 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).&lt;/p&gt;
-
-&lt;p&gt;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
-&lt;a href=&quot;http://www.freedesktop.org/software/PackageKit/&quot;&gt;PackageKit&lt;/a&gt;,
-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&#39;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 &lt;tt&gt;isenkram&lt;/tt&gt; package and insert some hardware dongle
-and see if it is recognised.&lt;/p&gt;
-
-&lt;p&gt;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:&lt;/p&gt;

+                <pubDate>Fri, 7 Oct 2016 09:50:00 +0200</pubDate>
+               <description>&lt;p&gt;&lt;a href=&quot;http://packages.qa.debian.org/isenkram&quot;&gt;The Isenkram
+system&lt;/a&gt; provide a practical and easy way to figure out which
+packages support the hardware in a given machine.  The command line
+tool &lt;tt&gt;isenkram-lookup&lt;/tt&gt; 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 &lt;tt&gt;pcscd&lt;/tt&gt; if
+that package isn&#39;t already installed, and if you plug in a USB video
+camera the system will ask if you want to install &lt;tt&gt;cheese&lt;/tt&gt; if
+cheese is currently missing.  This already work just fine.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Using_appstream_with_isenkram_to_install_hardware_related_packages_in_Debian.html&quot;&gt;a
+recipe on how to add such meta-information&lt;/a&gt; in a blog post last
+December.  If you have a hardware related package in Debian, please
+announce the relevant hardware IDs using AppStream.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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 &lt;tt&gt;/lib/udev/rules.d/70-udev-acl.rules&lt;/tt&gt;
+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.&lt;/p&gt;
+
+&lt;p&gt;The new system uses a udev tag, &#39;uaccess&#39;.  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
+&lt;tt&gt;/lib/udev/rules.d/60-nqc.rules&lt;/tt&gt; file now look like this:
+
+&lt;p&gt;&lt;pre&gt;
+SUBSYSTEM==&quot;usb&quot;, ACTION==&quot;add&quot;, ATTR{idVendor}==&quot;0694&quot;, ATTR{idProduct}==&quot;0001&quot;, \
+    SYMLINK+=&quot;rcx-%k&quot;, TAG+=&quot;uaccess&quot;
+&lt;/pre&gt;&lt;/p&gt;
+
+&lt;p&gt;The key part is the &#39;TAG+=&quot;uaccess&quot;&#39; 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
+&lt;tt&gt;70-uaccess.rules&lt;/tt&gt;).  Perhaps a lintian check should be created
+to detect this?&lt;/p&gt;
+
+&lt;p&gt;I&#39;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
+&lt;tt&gt;/lib/udev/rules.d/70-udev-acl.rules&lt;/tt&gt;.  If it is, I guess the
+indirect method is the preferred way.  Michael
+&lt;a href=&quot;https://github.com/systemd/systemd/issues/4288&quot;&gt;asked for more
+documentation from the systemd project&lt;/a&gt; and I hope it will make
+this clearer.  For now I use the generic classes when they exist and
+is already handled by &lt;tt&gt;70-uaccess.rules&lt;/tt&gt;, and add the tag
+directly if no such class exist.&lt;/p&gt;

-               <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>&lt;p&gt;Yesterday I updated the
-&lt;a href=&quot;https://tracker.debian.org/pkg/battery-stats&quot;&gt;battery-stats
-package in Debian&lt;/a&gt; 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.&lt;/p&gt;
-
-&lt;p&gt;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.&lt;/p&gt;
-
-&lt;p align=&quot;center&quot;&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2016-05-23-battery-stats-rate.png&quot;/&gt;&lt;/p&gt;
-
-&lt;p&gt;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:
-
-&lt;p align=&quot;center&quot;&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2016-05-23-battery-stats-history.png&quot;/&gt;&lt;/p&gt;
-
-&lt;p&gt;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. :(&lt;/p&gt;
-
-&lt;p&gt;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.&lt;/p&gt;
-
-&lt;p&gt;If you are interested in how your laptop battery is doing, please
-check out the
-&lt;a href=&quot;https://tracker.debian.org/pkg/battery-stats&quot;&gt;battery-stats&lt;/a&gt;
-in Debian unstable, or rebuild it on Jessie to get it working on
-Debian stable. :) The upstream source is available from &lt;a
-href=&quot;https://github.com/petterreinholdtsen/battery-stats&quot;&gt;github&lt;/a&gt;.
-Patches are very welcome.&lt;/p&gt;

+               <description>&lt;p&gt;En av dagens nyheter er at Aftenpostens redaktør Espen Egil Hansen
+bruker
+&lt;a href=&quot;https://www.nrk.no/kultur/aftenposten-brukar-heile-forsida-pa-facebook-kritikk-1.13126918&quot;&gt;forsiden
+av papiravisen på et åpent brev til Facebooks sjef Mark Zuckerberg om
+Facebooks fjerning av bilder, tekster og sider de ikke liker&lt;/a&gt;.  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
+&lt;a href=&quot;https://stallman.org/facebook.html&quot;&gt;Richard Stallmans side om
+Facebook&lt;/a&gt;.
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;Men det vil nok ta tid, i et Norge der de fleste nettredaktører
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Snurpenot_overv_kning_av_sensitiv_personinformasjon.html&quot;&gt;deler
+sine leseres personopplysinger med utenlands etterretning&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;For øvrig burde varsleren Edward Snowden få politisk asyl i
+Norge.&lt;/p&gt;

-               <description>&lt;p&gt;A few weeks ago the French paperback edition of Lawrence Lessigs
-2004 book Cultura Libre was published.  Today I noticed that the book
-is now available from book stores.  You can now buy it from
-&lt;a href=&quot;http://www.amazon.com/Culture-Libre-French-Lawrence-Lessig/dp/8269018260&quot;&gt;Amazon&lt;/a&gt;
-($19.99),
-&lt;a href=&quot;http://www.barnesandnoble.com/w/culture-libre-lawrence-lessig/1123776705&quot;&gt;Barnes
-&amp; Noble&lt;/a&gt; ($?) and as always from
-&lt;a href=&quot;http://www.lulu.com/shop/lawrence-lessig/culture-libre/paperback/product-22645082.html&quot;&gt;Lulu.com&lt;/a&gt;
-($19.99).  The revenue is donated to the Creative Commons project.  If
-you buy from Lulu.com, they currently get $10.59, while if you buy
-from one of the book stores most of the revenue go to the book store
-and the Creative Commons project get much (not sure how much
-less).&lt;/p&gt;
-
-&lt;p&gt;I was a bit surprised to discover that there is a kindle edition
-sold by Amazon Digital Services LLC on Amazon.  Not quite sure how
-that edition was created, but if you want to download a electronic
-edition (PDF, EPUB, Mobi) generated from the same files used to create
-the paperback edition, they are

+                <pubDate>Tue, 6 Sep 2016 23:00:00 +0200</pubDate>
+               <description>&lt;p&gt;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
+&lt;a href=&quot;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&quot;&gt;forslag
+om at e-tjenesten skal få lov til a avlytte all Internett-trafikk&lt;/a&gt;
+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.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p
+
+&lt;p&gt;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 &lt;a href=&quot;http://ipinfo.io/&quot;&gt;ipinfo.io&lt;/a&gt;
+for å få en ide om hvor i verden en IP-adresse hører til.&lt;/p&gt;
+
+&lt;p&gt;På den positive siden vil forslaget gjøre at enda flere blir
+motivert til å ta grep for å bruke
+&lt;a href=&quot;https://www.torproject.org/&quot;&gt;Tor&lt;/a&gt; og krypterte
+kommunikasjonsløsninger for å kommunisere med sine kjære, for å sikre
+at privatsfæren vernes.  Selv bruker jeg blant annet
+&lt;a href=&quot;https://www.freedomboxfoundation.org/&quot;&gt;FreedomBox&lt;/a&gt; og
+&lt;a href=&quot;https://whispersystems.org/&quot;&gt;Signal&lt;/a&gt; til slikt.  Ingen av
+dem er optimale, men de fungerer ganske bra allerede og øker kostnaden
+for dem som ønsker å invadere mitt privatliv.&lt;/p&gt;
+
+&lt;p&gt;For øvrig burde varsleren Edward Snowden få politisk asyl i
+Norge.&lt;/p&gt;

-                <pubDate>Thu, 19 May 2016 14:00:00 +0200</pubDate>
-               <description>&lt;p&gt;I just donated to the
-&lt;a href=&quot;http://www.nuug.no/dns-beslag-donasjon.shtml&quot;&gt;NUUG defence
-&quot;fond&quot;&lt;/a&gt; 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.&lt;/p&gt;
-
-&lt;p&gt;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.&lt;/p&gt;
-
-&lt;p&gt;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
-&lt;a href=&quot;https://web.archive.org/web/*/http://popcorn-time.no&quot;&gt;the web
-site content on the Internet Archive&lt;/A&gt;, and only found news coverage
-about Popcorn Time, not any material published without the right
-holders permissions.&lt;/p&gt;
-
-&lt;p&gt;The seizure was widely covered in the Norwegian press (see for
-example &lt;a href=&quot;http://www.hegnar.no/Nyheter/Naeringsliv/2016/03/Popcorn-time.no-beslaglagt-av-OEkokrim&quot;&gt;Hegnar Online&lt;/a&gt; and
-&lt;a href=&quot;http://itavisen.no/2016/03/08/okokrim-har-beslaglagt-popcorn-time-no/&quot;&gt;ITavisen&lt;a/&gt;
-and
-&lt;a href=&quot;http://www.nrk.no/kultur/okokrim-gar-til-aksjon-mot-popcorn-time-1.12842452&quot;&gt;NRK&lt;/a&gt;),
-at first due to the press release sent out by Økokrim, but then based
-on
-&lt;a href=&quot;http://blogg.torvund.net/2016/03/09/okokrims-beslag-i-domenet-popcorn-time-no/&quot;&gt;protests
-from the law professor Olav Torvund&lt;/a&gt; and
-&lt;a href=&quot;http://www.klassekampen.no/article/20160311/ARTICLE/160319995&quot;&gt;lawyer
-Jon Wessel-Aas&lt;/a&gt;.  It even got some
-&lt;a href=&quot;https://torrentfreak.com/norwegian-authorities-sued-over-popcorn-time-domain-seizure-160418/&quot;&gt;coverage
-on TorrentFreak&lt;/a&gt;.&lt;/p&gt;
-
-&lt;p&gt;I
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/NUUG_contests_Norwegian_police_DNS_seizure_of_popcorn_time_no.html&quot;&gt;
-wrote about the case a month ago&lt;/a&gt;, when the
-&lt;a href=&quot;http://www.nuug.no/&quot;&gt;Norwegian Unix User Group&lt;/a&gt; (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.&lt;/p&gt;
-
-&lt;p&gt;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 &lt;a href=&quot;http://www.nuug.no/dns-beslag-donasjon.shtml&quot;&gt;show
-your support by donating to NUUG&lt;/a&gt;.&lt;/a&gt;

+               <description>&lt;p&gt;In April we
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Lets_make_a_Norwegian_Bokm_l_edition_of_The_Debian_Administrator_s_Handbook.html&quot;&gt;started
+to work&lt;/a&gt; on a Norwegian Bokmål edition of the &quot;open access&quot; book on
+how to set up and administrate a Debian system.  Today I am happy to
+report that the first draft is now publicly available.  You can find
+it on &lt;a href=&quot;https://debian-handbook.info/get/&quot;&gt;get the Debian
+Administrator&#39;s Handbook page&lt;/a&gt; (under Other languages).  The first
+eight chapters have a first draft translation, and we are working on
+proofreading the content.  If you want to help out, please start
+contributing using
+&lt;a href=&quot;https://hosted.weblate.org/projects/debian-handbook/&quot;&gt;the

+contributors&lt;/a&gt;.  A good way to contribute is to proofread the text
+and update weblate if you find errors.&lt;/p&gt;
+

-&lt;a href=&quot;http://zfsonlinux.org/&quot;&gt;ZFS for Linux&lt;/a&gt; finally entered

+                <pubDate>Thu, 11 Aug 2016 12:00:00 +0200</pubDate>
+               <description>&lt;p&gt;This summer, I read a great article
+&quot;&lt;a href=&quot;https://www.usenix.org/publications/login/summer2016/curtsinger&quot;&gt;coz:
+This Is the Profiler You&#39;re Looking For&lt;/a&gt;&quot; 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 &quot;speeding up&quot; parts of
+the code to various degrees compared to a normal run.  It does this by
+slowing down parallel threads while the &quot;faster up&quot; 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.&lt;/p&gt;
+
+&lt;p&gt;The project and presentation was so inspiring that I would like to
+get the system into Debian.  I
+&lt;a href=&quot;https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=830708&quot;&gt;created
+a WNPP request for it&lt;/a&gt; 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 &#39;git clone&#39; 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.&lt;/p&gt;
+
+&lt;p&gt;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:
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+coz run --- program-to-run
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;http://plasma-umass.github.io/coz/&quot;&gt;http://plasma-umass.github.io/coz/&lt;/a&gt;
+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 &amp;lt;coz.h&amp;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.&lt;/p&gt;
+
+&lt;p&gt;A video published by ACM
+&lt;a href=&quot;https://www.youtube.com/watch?v=jE0V-p1odPg&quot;&gt;presenting the
+Coz profiler&lt;/a&gt; is available from Youtube.  There is also a paper
+from the 25th Symposium on Operating Systems Principles available
+titled
+&lt;a href=&quot;https://www.usenix.org/conference/atc16/technical-sessions/presentation/curtsinger&quot;&gt;Coz:
+finding code that counts with causal profiling&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;&lt;a href=&quot;https://github.com/plasma-umass/coz&quot;&gt;The source code&lt;/a&gt;
+for Coz is available from github.  It will only build with clang
+because it uses a
+&lt;a href=&quot;https://gcc.gnu.org/bugzilla/show_bug.cgi?id=55606&quot;&gt;C++
+feature missing in GCC&lt;/a&gt;, but I&#39;ve submitted
+&lt;a href=&quot;https://github.com/plasma-umass/coz/pull/67&quot;&gt;a patch to solve
+it&lt;/a&gt; and hope it will be included in the upstream source soon.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;

-               <description>&lt;p&gt;&lt;strong&gt;Where I set out to figure out which multimedia player in
-Debian claim support for most file formats.&lt;/strong&gt;&lt;/p&gt;
-
-&lt;p&gt;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.
-&lt;a href=&quot;https://wiki.debian.org/DebianEdu/BrowserMultimedia&quot;&gt;The
-result&lt;/a&gt; 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.&lt;/p&gt;
-
-&lt;p&gt;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
-&lt;a href=&quot;https://bugs.debian.org/822245&quot;&gt;missing MIME type in the VLC
-desktop file&lt;/a&gt;.  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.&lt;/p&gt;
-
-&lt;p&gt;The result can be seen on the Debian Wiki, as
-&lt;a href=&quot;https://wiki.debian.org/DebianMultimedia/PlayerSupport&quot;&gt;a
-table listing all MIME types supported by one of the packages included
-in the table&lt;/a&gt;, with the package supporting most MIME types being
-listed first in the table.&lt;/p&gt;
-
-&lt;/p&gt;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?&lt;/p&gt;

+               <description>&lt;p&gt;As my regular readers probably remember, the last year I published
+a French and Norwegian translation of the classic
+&lt;a href=&quot;http://www.free-culture.cc/&quot;&gt;Free Culture book&lt;/a&gt; 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.&lt;/p&gt;
+
+&lt;p&gt;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:&lt;/p&gt;
+
+&lt;table border=&quot;0&quot;&gt;
+&lt;tr&gt;&lt;th&gt;Title / language&lt;/th&gt;&lt;th&gt;Quantity&lt;/th&gt;&lt;/tr&gt;
+&lt;tr&gt;&lt;td&gt;&lt;a href=&quot;http://www.lulu.com/shop/lawrence-lessig/culture-libre/paperback/product-22645082.html&quot;&gt;Culture Libre / French&lt;/a&gt;&lt;/td&gt;&lt;td align=&quot;right&quot;&gt;3&lt;/td&gt;&lt;/tr&gt;
+&lt;tr&gt;&lt;td&gt;&lt;a href=&quot;http://www.lulu.com/shop/lawrence-lessig/fri-kultur/paperback/product-22441576.html&quot;&gt;Fri kultur / Norwegian&lt;/a&gt;&lt;/td&gt;&lt;td align=&quot;right&quot;&gt;7&lt;/td&gt;&lt;/tr&gt;
+&lt;tr&gt;&lt;td&gt;&lt;a href=&quot;http://www.lulu.com/shop/lawrence-lessig/free-culture/paperback/product-22440520.html&quot;&gt;Free Culture / English&lt;/a&gt;&lt;/td&gt;&lt;td align=&quot;right&quot;&gt;14&lt;/td&gt;&lt;/tr&gt;
+&lt;/table&gt;
+
+&lt;p&gt;The books are available both from Lulu.com and from large book
+stores like Amazon and Barnes&amp;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.&lt;/p&gt;
+
+&lt;p&gt;The ebook edition is available for free from
+&lt;a href=&quot;https://github.com/petterreinholdtsen/free-culture-lessig&quot;&gt;Github&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
