-               <description>&lt;p&gt;Back in September, I blogged about
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/The_life_and_death_of_a_laptop_battery.html&quot;&gt;the
-system I wrote to collect statistics about my laptop battery&lt;/a&gt;, and
-how it showed the decay and death of this battery (now replaced).  I
-created a simple deb package to handle the collection and graphing,
-but did not want to upload it to Debian as there were already
-&lt;a href=&quot;https://tracker.debian.org/pkg/battery-stats&quot;&gt;a battery-stats
-package in Debian&lt;/a&gt; that should do the same thing, and I did not see
-a point of uploading a competing package when battery-stats could be
-fixed instead.  I reported a few bugs about its non-function, and
-hoped someone would step in and fix it.  But no-one did.&lt;/p&gt;
-
-&lt;p&gt;I got tired of waiting a few days ago, and took matters in my own
-hands.  The end result is that I am now the new upstream developer of
-battery stats (&lt;a href=&quot;https://github.com/petterreinholdtsen/battery-stats&quot;&gt;available from github&lt;/a&gt;) and part of the team maintaining
-battery-stats in Debian, and the package in Debian unstable is finally
-able to collect battery status using the /sys/class/power_supply/
-information provided by the Linux kernel.  If you install the
-battery-stats package from unstable now, you will be able to get a
-graph of the current battery fill level, to get some idea about the
-status of the battery.  The source package build and work just fine in
-Debian testing and stable (and probably oldstable too, but I have not
-tested).  The default graph you get for that system look like this:&lt;/p&gt;
-
-&lt;p align=&quot;center&quot;&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2016-03-15-battery-stats-graph-example.png&quot; width=&quot;70%&quot; align=&quot;center&quot;&gt;&lt;/p&gt;
-
-&lt;p&gt;My plans for the future is to merge my old scripts into the
-battery-stats package, as my old scripts collected a lot more details
-about the battery.  The scripts are merged into the upstream
-battery-stats git repository already, but I am not convinced they work
-yet, as I changed a lot of paths along the way.  Will have to test a
-bit more before I make a new release.&lt;/p&gt;
-
-&lt;p&gt;I will also consider changing the file format slightly, as I
-suspect the way I combine several values into one field might make it
-impossible to know the type of the value when using it for processing
-and graphing.&lt;/p&gt;
-
-&lt;p&gt;If you would like I would like to keep an close eye on your laptop
-battery, check out the battery-stats package in
-&lt;a href=&quot;https://tracker.debian.org/pkg/battery-stats&quot;&gt;Debian&lt;/a&gt; and
-on
-&lt;a href=&quot;https://github.com/petterreinholdtsen/battery-stats&quot;&gt;github&lt;/a&gt;.
-I would love some help to improve the system further.&lt;/p&gt;

+                <pubDate>Thu, 9 Mar 2017 15:20:00 +0100</pubDate>
+               <description>&lt;p&gt;Over the years, administrating thousand of NFS mounting linux
+computers at the time, I often needed a way to detect if the machine
+was experiencing NFS hang.  If you try to use &lt;tt&gt;df&lt;/tt&gt; or look at a
+file or directory affected by the hang, the process (and possibly the
+shell) will hang too.  So you want to be able to detect this without
+risking the detection process getting stuck too.  It has not been
+obvious how to do this.  When the hang has lasted a while, it is
+possible to find messages like these in dmesg:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;
+nfs: server nfsserver not responding, still trying
+&lt;br&gt;nfs: server nfsserver OK
+&lt;/blockquote&gt;&lt;/p&gt;
+  
+&lt;p&gt;It is hard to know if the hang is still going on, and it is hard to
+be sure looking in dmesg is going to work.  If there are lots of other
+messages in dmesg the lines might have rotated out of site before they
+are noticed.&lt;/p&gt;
+
+&lt;p&gt;While reading through the nfs client implementation in linux kernel
+code, I came across some statistics that seem to give a way to detect
+it.  The om_timeouts sunrpc value in the kernel will increase every
+time the above log entry is inserted into dmesg.  And after digging a
+bit further, I discovered that this value show up in
+/proc/self/mountstats on Linux.&lt;/p&gt;
+
+&lt;p&gt;The mountstats content seem to be shared between files using the
+same file system context, so it is enough to check one of the
+mountstats files to get the state of the mount point for the machine.
+I assume this will not show lazy umounted NFS points, nor NFS mount
+points in a different process context (ie with a different filesystem
+view), but that does not worry me.&lt;/p&gt;
+
+&lt;p&gt;The content for a NFS mount point look similar to this:&lt;/p&gt;
+

+[...]
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;The key number to look at is the third number in the per-op list.
+It is the number of NFS timeouts experiences per file system
+operation.  Here 22 write timeouts and 5 access timeouts.  If these
+numbers are increasing, I believe the machine is experiencing NFS
+hang.  Unfortunately the timeout value do not start to increase right
+away.  The NFS operations need to time out first, and this can take a
+while.  The exact timeout value depend on the setup.  For example the
+defaults for TCP and UDP mount points are quite different, and the
+timeout value is affected by the soft, hard, timeo and retrans NFS
+mount options.&lt;/p&gt;
+
+&lt;p&gt;The only way I have been able to get working on Debian and RedHat
+Enterprise Linux for getting the timeout count is to peek in /proc/.
+But according to
+&lt;ahref=&quot;http://docs.oracle.com/cd/E19253-01/816-4555/netmonitor-12/index.html&quot;&gt;Solaris
+10 System Administration Guide: Network Services&lt;/a&gt;, the &#39;nfsstat -c&#39;
+command can be used to get these timeout values.  But this do not work
+on Linux, as far as I can tell.  I
+&lt;ahref=&quot;http://bugs.debian.org/857043&quot;&gt;asked Debian about this&lt;/a&gt;,
+but have not seen any replies yet.&lt;/p&gt;
+
+&lt;p&gt;Is there a better way to figure out if a Linux NFS client is
+experiencing NFS hangs?  Is there a way to detect which processes are
+affected?  Is there a way to get the NFS mount going quickly once the
+network problem causing the NFS hang has been cleared?  I would very
+much welcome some clues, as we regularly run into NFS hangs.&lt;/p&gt;

-               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Creating__updating_and_checking_debian_copyright_semi_automatically.html</guid>
-                <pubDate>Fri, 19 Feb 2016 15:00:00 +0100</pubDate>
-               <description>&lt;p&gt;Making packages for Debian requires quite a lot of attention to
-details.  And one of the details is the content of the
-debian/copyright file, which should list all relevant licenses used by
-the code in the package in question, preferably in
-&lt;a href=&quot;https://www.debian.org/doc/packaging-manuals/copyright-format/1.0/&quot;&gt;machine
-readable DEP5 format&lt;/a&gt;.&lt;/p&gt;
-
-&lt;p&gt;For large packages with lots of contributors it is hard to write
-and update this file manually, and if you get some detail wrong, the
-package is normally rejected by the ftpmasters.  So getting it right
-the first time around get the package into Debian faster, and save
-both you and the ftpmasters some work..  Today, while trying to figure
-out what was wrong with
-&lt;a href=&quot;https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=686447&quot;&gt;the
-zfsonlinux copyright file&lt;/a&gt;, I decided to spend some time on
-figuring out the options for doing this job automatically, or at least
-semi-automatically.&lt;/p&gt;
-
-&lt;p&gt;Lucikly, there are at least two tools available for generating the
-file based on the code in the source package,
-&lt;tt&gt;&lt;a href=&quot;https://tracker.debian.org/pkg/debmake&quot;&gt;debmake&lt;/a&gt;&lt;/tt&gt;
-and &lt;tt&gt;&lt;a href=&quot;https://tracker.debian.org/pkg/cme&quot;&gt;cme&lt;/a&gt;&lt;/tt&gt;.  I&#39;m
-not sure which one of them came first, but both seem to be able to
-create a sensible draft file.  As far as I can tell, none of them can
-be trusted to get the result just right, so the content need to be
-polished a bit before the file is OK to upload.  I found the debmake
-option in
-&lt;a href=&quot;http://goofying-with-debian.blogspot.com/2014/07/debmake-checking-source-against-dep-5.html&quot;&gt;a
-blog posts from 2014&lt;/a&gt;.
-
-&lt;p&gt;To generate using debmake, use the -cc option:
-
-&lt;p&gt;&lt;pre&gt;
-debmake -cc &gt; debian/copyright
-&lt;/pre&gt;&lt;/p&gt;
-
-&lt;p&gt;Note there are some problems with python and non-ASCII names, so
-this might not be the best option.&lt;/p&gt;
-
-&lt;p&gt;The cme option is based on a config parsing library, and I found
-this approach in
-&lt;a href=&quot;https://ddumont.wordpress.com/2015/04/05/improving-creation-of-debian-copyright-file/&quot;&gt;a
-blog post from 2015&lt;/a&gt;.  To generate using cme, use the &#39;update
-dpkg-copyright&#39; option:
-
-&lt;p&gt;&lt;pre&gt;
-cme update dpkg-copyright
-&lt;/pre&gt;&lt;/p&gt;
-
-&lt;p&gt;This will create or update debian/copyright.  The cme tool seem to
-handle UTF-8 names better than debmake.&lt;/p&gt;
-
-&lt;p&gt;When the copyright file is created, I would also like some help to
-check if the file is correct.  For this I found two good options,
-&lt;tt&gt;debmake -k&lt;/tt&gt; and &lt;tt&gt;license-reconcile&lt;/tt&gt;.  The former seem
-to focus on license types and file matching, and is able to detect
-ineffective blocks in the copyright file.  The latter reports missing
-copyright holders and years, but was confused by inconsistent license
-names (like CDDL vs. CDDL-1.0).  I suspect it is good to use both and
-fix all issues reported by them before uploading.  But I do not know
-if the tools and the ftpmasters agree on what is important to fix in a
-copyright file, so the package might still be rejected.&lt;/p&gt;
-
-&lt;p&gt;The devscripts tool &lt;tt&gt;licensecheck&lt;/tt&gt; deserve mentioning.  It
-will read through the source and try to find all copyright statements.
-It is not comparing the result to the content of debian/copyright, but
-can be useful when verifying the content of the copyright file.&lt;/p&gt;
-
-&lt;p&gt;Are you aware of better tools in Debian to create and update
-debian/copyright file.  Please let me know, or blog about it on
-planet.debian.org.&lt;/p&gt;
-
-&lt;p&gt;As usual, if you use Bitcoin and want to show your support of my
-activities, please send Bitcoin donations to my address
-&lt;b&gt;&lt;a href=&quot;bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&quot;&gt;15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&lt;/a&gt;&lt;/b&gt;.&lt;/p&gt;
-
-&lt;p&gt;&lt;strong&gt;Update 2016-02-20&lt;/strong&gt;: I got a tip from Mike Gabriel
-on how to use licensecheck and cdbs to create a draft copyright file
-
-&lt;p&gt;&lt;pre&gt;
-licensecheck --copyright -r `find * -type f` | \
-  /usr/lib/cdbs/licensecheck2dep5 &gt; debian/copyright.auto
-&lt;/pre&gt;&lt;/p&gt;
-
-&lt;p&gt;He mentioned that he normally check the generated file into the
-version control system to make it easier to discover license and
-copyright changes in the upstream source.  I will try to do the same
-with my packages in the future.&lt;/p&gt;
-
-&lt;p&gt;&lt;strong&gt;Update 2016-02-21&lt;/strong&gt;: The cme author recommended
-against using -quiet for new users, so I removed it from the proposed
-command line.&lt;/p&gt;

+               <description>&lt;p&gt;So the new president in the United States of America claim to be
+surprised to discover that he was wiretapped during the election
+before he was elected president.  He even claim this must be illegal.
+Well, doh, if it is one thing the confirmations from Snowden
+documented, it is that the entire population in USA is wiretapped, one
+way or another.  Of course the president candidates were wiretapped,
+alongside the senators, judges and the rest of the people in USA.&lt;/p&gt;
+
+&lt;p&gt;Next, the Federal Bureau of Investigation ask the Department of
+Justice to go public rejecting the claims that Donald Trump was
+wiretapped illegally.  I fail to see the relevance, given that I am
+sure the surveillance industry in USA believe they have all the legal
+backing they need to conduct mass surveillance on the entire
+world.&lt;/p&gt;
+
+&lt;p&gt;There is even the director of the FBI stating that he never saw an
+order requesting wiretapping of Donald Trump.  That is not very
+surprising, given how the FISA court work, with all its activity being
+secret.  Perhaps he only heard about it?&lt;/p&gt;
+
+&lt;p&gt;What I find most sad in this story is how Norwegian journalists
+present it.  In a news reports the other day in the radio from the
+Norwegian National broadcasting Company (NRK), I heard the journalist
+claim that &#39;the FBI denies any wiretapping&#39;, while the reality is that
+&#39;the FBI denies any illegal wiretapping&#39;.  There is a fundamental and
+important difference, and it make me sad that the journalists are
+unable to grasp it.&lt;/p&gt;

+&lt;p&gt;&lt;strong&gt;Update 2017-03-13:&lt;/strong&gt; Look like

+               <description>&lt;p&gt;For almost a year now, we have been working on making a Norwegian
+Bokmål edition of &lt;a href=&quot;https://debian-handbook.info/&quot;&gt;The Debian
+Administrator&#39;s Handbook&lt;/a&gt;.  Now, thanks to the tireless effort of
+Ole-Erik, Ingrid and Andreas, the initial translation is complete, and
+we are working on the proof reading to ensure consistent language and
+use of correct computer science terms.  The plan is to make the book
+available on paper, as well as in electronic form.  For that to
+happen, the proof reading must be completed and all the figures need
+to be translated.  If you want to help out, get in touch.&lt;/p&gt;
+
+&lt;p&gt;&lt;a href=&quot;http://people.skolelinux.org/pere/debian-handbook/debian-handbook-nb-NO.pdf&quot;&gt;A
+
+fresh PDF edition&lt;/a&gt; in A4 format (the final book will have smaller
+pages) of the book created every morning is available for
+proofreading.  If you find any errors, please
+&lt;a href=&quot;https://hosted.weblate.org/projects/debian-handbook/&quot;&gt;visit
+Weblate and correct the error&lt;/a&gt;.  The
+&lt;a href=&quot;http://l.github.io/debian-handbook/stat/nb-NO/index.html&quot;&gt;state
+of the translation including figures&lt;/a&gt; is a useful source for those
+provide Norwegian bokmål screen shots and figures.&lt;/p&gt;

-               <description>&lt;p&gt;The &lt;a href=&quot;https://wiki.debian.org/DEP-11&quot;&gt;appstream system&lt;/a&gt;
-is taking shape in Debian, and one provided feature is a very
-convenient way to tell you which package to install to make a given
-firmware file available when the kernel is looking for it.  This can
-be done using apt-file too, but that is for someone else to blog
-about. :)&lt;/p&gt;
-
-&lt;p&gt;Here is a small recipe to find the package with a given firmware
-file, in this example I am looking for ctfw-3.2.3.0.bin, randomly
-picked from the set of firmware announced using appstream in Debian
-unstable.  In general you would be looking for the firmware requested
-by the kernel during kernel module loading.  To find the package
-providing the example file, do like this:&lt;/p&gt;

+               <link>http://people.skolelinux.org/pere/blog/Unlimited_randomness_with_the_ChaosKey_.html</link>
+               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Unlimited_randomness_with_the_ChaosKey_.html</guid>
+                <pubDate>Wed, 1 Mar 2017 20:50:00 +0100</pubDate>
+               <description>&lt;p&gt;A few days ago I ordered a small batch of
+&lt;a href=&quot;http://altusmetrum.org/ChaosKey/&quot;&gt;the ChaosKey&lt;/a&gt;, a small
+USB dongle for generating entropy created by Bdale Garbee and Keith
+Packard.  Yesterday it arrived, and I am very happy to report that it
+work great!  According to its designers, to get it to work out of the
+box, you need the Linux kernel version 4.1 or later.  I tested on a
+Debian Stretch machine (kernel version 4.9), and there it worked just
+fine, increasing the available entropy very quickly.  I wrote a small
+test oneliner to test.  It first print the current entropy level,
+drain /dev/random, and then print the entropy level for five seconds.
+Here is the situation without the ChaosKey inserted:&lt;/p&gt;

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

-% apt install appstream
-[...]
-% apt update
-[...]
-% appstreamcli what-provides firmware:runtime ctfw-3.2.3.0.bin | \
-  awk &#39;/Package:/ {print $2}&#39;
-firmware-qlogic
+% cat /proc/sys/kernel/random/entropy_avail; \
+  dd bs=1M if=/dev/random of=/dev/null count=1; \
+  for n in $(seq 1 5); do \
+     cat /proc/sys/kernel/random/entropy_avail; \
+     sleep 1; \
+  done

+21

 %
 &lt;/pre&gt;&lt;/blockquote&gt;
 
 %
 &lt;/pre&gt;&lt;/blockquote&gt;
 

-&lt;p&gt;See &lt;a href=&quot;https://wiki.debian.org/AppStream/Guidelines&quot;&gt;the
-appstream wiki&lt;/a&gt; page to learn how to embed the package metadata in
-a way appstream can use.&lt;/p&gt;
-
-&lt;p&gt;This same approach can be used to find any package supporting a
-given MIME type.  This is very useful when you get a file you do not
-know how to handle.  First find the mime type using &lt;tt&gt;file
---mime-type&lt;/tt&gt;, and next look up the package providing support for
-it.  Lets say you got an SVG file.  Its MIME type is image/svg+xml,
-and you can find all packages handling this type like this:&lt;/p&gt;
+&lt;p&gt;The entropy level increases by 3-4 every second.  In such case any
+application requiring random bits (like a HTTPS enabled web server)
+will halt and wait for more entrpy.  And here is the situation with
+the ChaosKey inserted:&lt;/p&gt;

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

-% apt install appstream
-[...]
-% apt update
-[...]
-% appstreamcli what-provides mimetype image/svg+xml | \
-  awk &#39;/Package:/ {print $2}&#39;

-&lt;p&gt;I believe the MIME types are fetched from the desktop file for
-packages providing appstream metadata.&lt;/p&gt;

-               <description>&lt;p&gt;Most people seem not to realise that every time they walk around
-with the computerised radio beacon known as a mobile phone their
-position is tracked by the phone company and often stored for a long
-time (like every time a SMS is received or sent).  And if their
-computerised radio beacon is capable of running programs (often called
-mobile apps) downloaded from the Internet, these programs are often
-also capable of tracking their location (if the app requested access
-during installation).  And when these programs send out information to
-central collection points, the location is often included, unless
-extra care is taken to not send the location.  The provided
-information is used by several entities, for good and bad (what is
-good and bad, depend on your point of view).  What is certain, is that
-the private sphere and the right to free movement is challenged and
-perhaps even eradicated for those announcing their location this way,
-when they share their whereabouts with private and public
-entities.&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/2016-01-24-nice-creepy-desktop-window.png&quot;&gt;&lt;/p&gt;
-
-&lt;p&gt;The phone company logs provide a register of locations to check out
-when one want to figure out what the tracked person was doing.  It is
-unavailable for most of us, but provided to selected government
-officials, company staff, those illegally buying information from
-unfaithful servants and crackers stealing the information.  But the
-public information can be collected and analysed, and a free software
-tool to do so is called
-&lt;a href=&quot;http://www.geocreepy.com/&quot;&gt;Creepy or Cree.py&lt;/a&gt;.  I
-discovered it when I read
-&lt;a href=&quot;http://www.aftenposten.no/kultur/Slik-kan-du-bli-overvaket-pa-Twitter-og-Instagram-uten-a-ane-det-7787884.html&quot;&gt;an
-article about Creepy&lt;/a&gt; in the Norwegian newspaper Aftenposten i
-November 2014, and decided to check if it was available in Debian.
-The python program was in Debian, but
-&lt;a href=&quot;https://tracker.debian.org/pkg/creepy&quot;&gt;the version in
-Debian&lt;/a&gt; was completely broken and practically unmaintained.  I
-uploaded a new version which did not work quite right, but did not
-have time to fix it then.  This Christmas I decided to finally try to
-get Creepy operational in Debian.  Now a fixed version is available in
-Debian unstable and testing, and almost all Debian specific patches
-are now included
-&lt;a href=&quot;https://github.com/jkakavas/creepy&quot;&gt;upstream&lt;/a&gt;.&lt;/p&gt;
-
-&lt;p&gt;The Creepy program visualises geolocation information fetched from
-Twitter, Instagram, Flickr and Google+, and allow one to get a
-complete picture of every social media message posted recently in a
-given area, or track the movement of a given individual across all
-these services.  Earlier it was possible to use the search API of at
-least some of these services without identifying oneself, but these
-days it is impossible.  This mean that to use Creepy, you need to
-configure it to log in as yourself on these services, and provide
-information to them about your search interests.  This should be taken
-into account when using Creepy, as it will also share information
-about yourself with the services.&lt;/p&gt;
-
-&lt;p&gt;The picture above show the twitter messages sent from (or at least
-geotagged with a position from) the city centre of Oslo, the capital
-of Norway.  One useful way to use Creepy is to first look at
-information tagged with an area of interest, and next look at all the
-information provided by one or more individuals who was in the area.
-I tested it by checking out which celebrity provide their location in
-twitter messages by checkout out who sent twitter messages near a
-Norwegian TV station, and next could track their position over time,
-making it possible to locate their home and work place, among other
-things.  A similar technique have been
-&lt;a href=&quot;http://www.buzzfeed.com/maxseddon/does-this-soldiers-instagram-account-prove-russia-is-covertl&quot;&gt;used
-to locate Russian soldiers in Ukraine&lt;/a&gt;, and it is both a powerful
-tool to discover lying governments, and a useful tool to help people
-understand the value of the private information they provide to the
-public.&lt;/p&gt;
-
-&lt;p&gt;The package is not trivial to backport to Debian Stable/Jessie, as
-it depend on several python modules currently missing in Jessie (at
-least python-instagram, python-flickrapi and
-python-requests-toolbelt).&lt;/p&gt;
-
-&lt;p&gt;(I have uploaded
-&lt;a href=&quot;https://screenshots.debian.net/package/creepy&quot;&gt;the image to
-screenshots.debian.net&lt;/a&gt; and licensed it under the same terms as the
-Creepy program in Debian.)&lt;/p&gt;
+&lt;p&gt;Quite the difference. :) I bought a few more than I need, in case
+someone want to buy one here in Norway. :)&lt;/p&gt;
+
+&lt;p&gt;Update: The dongle was presented at Debconf last year.  You might
+find &lt;a href=&quot;https://debconf16.debconf.org/talks/94/&quot;&gt;the talk
+recording illuminating&lt;/a&gt;.  It explains exactly what the source of
+randomness is, if you are unable to spot it from the schema drawing
+available from the ChaosKey web site linked at the start of this blog
+post.&lt;/p&gt;

-               <description>&lt;p&gt;During his DebConf15 keynote, Jacob Appelbaum
-&lt;a href=&quot;https://summit.debconf.org/debconf15/meeting/331/what-is-to-be-done/&quot;&gt;observed
-that those listening on the Internet lines would have good reason to
-believe a computer have a given security hole&lt;/a&gt; if it download a
-security fix from a Debian mirror.  This is a good reason to always
-use encrypted connections to the Debian mirror, to make sure those
-listening do not know which IP address to attack.  In August, Richard
-Hartmann observed that encryption was not enough, when it was possible
-to interfere download size to security patches or the fact that
-download took place shortly after a security fix was released, and
-&lt;a href=&quot;http://richardhartmann.de/blog/posts/2015/08/24-Tor-enabled_Debian_mirror/&quot;&gt;proposed
-to always use Tor to download packages from the Debian mirror&lt;/a&gt;.  He
-was not the first to propose this, as the
-&lt;tt&gt;&lt;a href=&quot;https://tracker.debian.org/pkg/apt-transport-tor&quot;&gt;apt-transport-tor&lt;/a&gt;&lt;/tt&gt;
-package by Tim Retout already existed to make it easy to convince apt
-to use &lt;a href=&quot;https://www.torproject.org/&quot;&gt;Tor&lt;/a&gt;, but I was not
-aware of that package when I read the blog post from Richard.&lt;/p&gt;
-
-&lt;p&gt;Richard discussed the idea with Peter Palfrader, one of the Debian
-sysadmins, and he set up a Tor hidden service on one of the central
-Debian mirrors using the address vwakviie2ienjx6t.onion, thus making
-it possible to download packages directly between two tor nodes,
-making sure the network traffic always were encrypted.&lt;/p&gt;
-
-&lt;p&gt;Here is a short recipe for enabling this on your machine, by
-installing &lt;tt&gt;apt-transport-tor&lt;/tt&gt; and replacing http and https
-urls with tor+http and tor+https, and using the hidden service instead
-of the official Debian mirror site.  I recommend installing
-&lt;tt&gt;etckeeper&lt;/tt&gt; before you start to have a history of the changes
-done in /etc/.&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-apt install apt-transport-tor
-sed -i &#39;s% http://ftp.debian.org/% tor+http://vwakviie2ienjx6t.onion/%&#39; /etc/apt/sources.list
-sed -i &#39;s% http% tor+http%&#39; /etc/apt/sources.list
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;If you have more sources listed in /etc/apt/sources.list.d/, run
-the sed commands for these too.  The sed command is assuming your are
-using the ftp.debian.org Debian mirror.  Adjust the command (or just
-edit the file manually) to match your mirror.&lt;/p&gt;
-
-&lt;p&gt;This work in Debian Jessie and later.  Note that tools like
-&lt;tt&gt;apt-file&lt;/tt&gt; only recently started using the apt transport
-system, and do not work with these tor+http URLs.  For
-&lt;tt&gt;apt-file&lt;/tt&gt; you need the version currently in experimental,
-which need a recent apt version currently only in unstable.  So if you
-need a working &lt;tt&gt;apt-file&lt;/tt&gt;, this is not for you.&lt;/p&gt;
-
-&lt;p&gt;Another advantage from this change is that your machine will start
-using Tor regularly and at fairly random intervals (every time you
-update the package lists or upgrade or install a new package), thus
-masking other Tor traffic done from the same machine.  Using Tor will
-become normal for the machine in question.&lt;/p&gt;
-
-&lt;p&gt;On &lt;a href=&quot;https://wiki.debian.org/FreedomBox&quot;&gt;Freedombox&lt;/a&gt;, APT
-is set up by default to use &lt;tt&gt;apt-transport-tor&lt;/tt&gt; when Tor is
-enabled.  It would be great if it was the default on any Debian
-system.&lt;/p&gt;

+               <description>&lt;p&gt;I just noticed

+new Norwegian proposal for archiving rules in the goverment&lt;/a&gt; list
+&lt;a href=&quot;http://www.ecma-international.org/publications/standards/Ecma-376.htm&quot;&gt;ECMA-376&lt;/a&gt;
+/ ISO/IEC 29500 (aka OOXML) as valid formats to put in long term
+storage.  Luckily such files will only be accepted based on
+pre-approval from the National Archive.  Allowing OOXML files to be
+used for long term storage might seem like a good idea as long as we
+forget that there are plenty of ways for a &quot;valid&quot; OOXML document to
+have content with no defined interpretation in the standard, which
+lead to a question and an idea.&lt;/p&gt;
+
+&lt;p&gt;Is there any tool to detect if a OOXML document depend on such
+undefined behaviour?  It would be useful for the National Archive (and
+anyone else interested in verifying that a document is well defined)
+to have such tool available when considering to approve the use of
+OOXML.  I&#39;m aware of the
+&lt;a href=&quot;https://github.com/arlm/officeotron/&quot;&gt;officeotron OOXML
+validator&lt;/a&gt;, but do not know how complete it is nor if it will
+report use of undefined behaviour.  Are there other similar tools
+available?  Please send me an email if you know of any such tool.&lt;/p&gt;

-               <description>&lt;p&gt;Det kommer stadig nye løsninger for å ta lagre unna innslag fra NRK
-for å se på det senere.  For en stund tilbake kom jeg over et script
-nrkopptak laget av Ingvar Hagelund.  Han fjernet riktignok sitt script
-etter forespørsel fra Erik Bolstad i NRK, men noen tok heldigvis og
-gjorde det &lt;a href=&quot;https://github.com/liangqi/nrkopptak&quot;&gt;tilgjengelig
-via github&lt;/a&gt;.&lt;/p&gt;
-
-&lt;p&gt;Scriptet kan lagre som MPEG4 eller Matroska, og bake inn
-undertekster i fila på et vis som blant annet VLC forstår.  For å
-bruke scriptet, kopier ned git-arkivet og kjør&lt;/p&gt;
-
-&lt;p&gt;&lt;pre&gt;
-nrkopptak/bin/nrk-opptak k &lt;ahref=&quot;https://tv.nrk.no/serie/bmi-turne/MUHH45000115/sesong-1/episode-1&quot;&gt;https://tv.nrk.no/serie/bmi-turne/MUHH45000115/sesong-1/episode-1&lt;/a&gt;
-&lt;/pre&gt;&lt;/p&gt;
-
-&lt;p&gt;URL-eksemplet er dagens toppsak på tv.nrk.no.  Argument &#39;k&#39; ber
-scriptet laste ned og lagre som Matroska.  Det finnes en rekke andre
-muligheter for valg av kvalitet og format.&lt;/p&gt;
-
-&lt;p&gt;Jeg foretrekker dette scriptet fremfor youtube-dl, som
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Hvordan_enkelt_laste_ned_filmer_fra_NRK_med_den__nye__l_sningen.html&quot;&gt;
-nevnt i 2014 støtter NRK&lt;/a&gt; og en rekke andre videokilder, på grunn
-av at nrkopptak samler undertekster og video i en enkelt fil, hvilket

+               <description>&lt;p&gt;A few days ago, we received the ruling from
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/A_day_in_court_challenging_seizure_of_popcorn_time_no_for__domstolkontroll.html&quot;&gt;my

+of the DNS domain popcorn-time.no.  The ruling simply did not mention

+face value, ignoring our demonstration and explanations.  But it is
+hard to tell for sure, as we still have not seen most of the documents
+in the case and thus were unprepared and unable to contradict several

-               <description>&lt;p&gt;When I was a kid, we used to collect &quot;car numbers&quot;, as we used to
-call the car license plate numbers in those days.  I would write the
-numbers down in my little book and compare notes with the other kids
-to see how many region codes we had seen and if we had seen some
-exotic or special region codes and numbers.  It was a fun game to pass
-time, as we kids have plenty of it.&lt;/p&gt;
-
-&lt;p&gt;A few days I came across
-&lt;a href=&quot;https://github.com/openalpr/openalpr&quot;&gt;the OpenALPR
-project&lt;/a&gt;, a free software project to automatically discover and
-report license plates in images and video streams, and provide the
-&quot;car numbers&quot; in a machine readable format.  I&#39;ve been looking for
-such system for a while now, because I believe it is a bad idea that the
-&lt;a href=&quot;https://en.wikipedia.org/wiki/Automatic_number_plate_recognition&quot;&gt;automatic
-number plate recognition&lt;/a&gt; tool only is available in the hands of
-the powerful, and want it to be available also for the powerless to
-even the score when it comes to surveillance and sousveillance.  I
-discovered the developer
-&lt;a href=&quot;https://bugs.debian.org/747509&quot;&gt;wanted to get the tool into
-Debian&lt;/a&gt;, and as I too wanted it to be in Debian, I volunteered to
-help him get it into shape to get the package uploaded into the Debian
-archive.&lt;/p&gt;
-
-&lt;p&gt;Today we finally managed to get the package into shape and uploaded
-it into Debian, where it currently
-&lt;a href=&quot;https://ftp-master.debian.org//new/openalpr_2.2.1-1.html&quot;&gt;waits
-in the NEW queue&lt;/a&gt; for review by the Debian ftpmasters.&lt;/p&gt;
-
-&lt;p&gt;I guess you are wondering why on earth such tool would be useful
-for the common folks, ie those not running a large government
-surveillance system?  Well, I plan to put it in a computer on my bike
-and in my car, tracking the cars nearby and allowing me to be notified
-when number plates on my watch list are discovered.  Another use case
-was suggested by a friend of mine, who wanted to set it up at his home
-to open the car port automatically when it discovered the plate on his
-car.  When I mentioned it perhaps was a bit foolhardy to allow anyone
-capable of placing his license plate number of a piece of cardboard to
-open his car port, men replied that it was always unlocked anyway.  I
-guess for such use case it make sense.  I am sure there are other use
-cases too, for those with imagination and a vision.&lt;/p&gt;
-
-&lt;p&gt;If you want to build your own version of the Debian package, check
-out the upstream git source and symlink ./distros/debian to ./debian/
-before running &quot;debuild&quot; to build the source.  Or wait a bit until the
-package show up in unstable.&lt;/p&gt;

+
+&lt;p&gt;On Wednesday, I spent the entire day in court in Follo Tingrett
+representing &lt;a href=&quot;https://www.nuug.no/&quot;&gt;the member association
+NUUG&lt;/a&gt;, alongside &lt;a href=&quot;https://www.efn.no/&quot;&gt;the member
+association EFN&lt;/a&gt; and &lt;a href=&quot;http://www.imc.no&quot;&gt;the DNS registrar
+IMC&lt;/a&gt;, challenging the seizure of the DNS name popcorn-time.no.  It
+was interesting to sit in a court of law for the first time in my
+life.  Our team can be seen in the picture above: attorney Ola
+Tellesbø, EFN board member Tom Fredrik Blenning, IMC CEO Morten Emil
+Eriksen and NUUG board member Petter Reinholdtsen.&lt;/p&gt;
+
+&lt;p&gt;&lt;a href=&quot;http://www.domstol.no/no/Enkelt-domstol/follo-tingrett/Nar-gar-rettssaken/Beramming/?cid=AAAA1701301512081262234UJFBVEZZZZZEJBAvtale&quot;&gt;The
+case at hand&lt;/a&gt; is that the Norwegian National Authority for
+Investigation and Prosecution of Economic and Environmental Crime (aka
+Økokrim) decided on their own, to seize a DNS domain early last
+year, without following
+&lt;a href=&quot;https://www.norid.no/no/regelverk/navnepolitikk/#link12&quot;&gt;the
+official policy of the Norwegian DNS authority&lt;/a&gt; which require a
+court decision.  The web site in question was a site covering Popcorn
+Time.  And Popcorn Time is the name of a technology with both legal
+and illegal applications.  Popcorn Time is a client combining
+searching a Bittorrent directory available on the Internet with
+downloading/distribute content via Bittorrent and playing the
+downloaded content on screen.  It can be used illegally if it is used
+to distribute content against the will of the right holder, but it can
+also be used legally to play a lot of content, for example the
+millions of movies
+&lt;a href=&quot;https://archive.org/details/movies&quot;&gt;available from the
+Internet Archive&lt;/a&gt; or the collection
+&lt;a href=&quot;http://vodo.net/films/&quot;&gt;available from Vodo&lt;/a&gt;.  We created
+&lt;a href=&quot;magnet:?xt=urn:btih:86c1802af5a667ca56d3918aecb7d3c0f7173084&amp;dn=PresentasjonFolloTingrett.mov&amp;tr=udp%3A%2F%2Fpublic.popcorn-tracker.org%3A6969%2Fannounce&quot;&gt;a
+video demonstrating legally use of Popcorn Time&lt;/a&gt; and played it in
+Court.  It can of course be downloaded using Bittorrent.&lt;/p&gt;
+
+&lt;p&gt;I did not quite know what to expect from a day in court.  The
+government held on to their version of the story and we held on to
+ours, and I hope the judge is able to make sense of it all.  We will
+know in two weeks time.  Unfortunately I do not have high hopes, as
+the Government have the upper hand here with more knowledge about the
+case, better training in handling criminal law and in general higher
+standing in the courts than fairly unknown DNS registrar and member
+associations.  It is expensive to be right also in Norway.  So far the
+case have cost more than NOK 70 000,-.  To help fund the case, NUUG
+and EFN have asked for donations, and managed to collect around NOK 25
+000,- so far.  Given the presentation from the Government, I expect
+the government to appeal if the case go our way.  And if the case do
+not go our way, I hope we have enough funding to appeal.&lt;/p&gt;
+
+&lt;p&gt;From the other side came two people from Økokrim.  On the benches,
+appearing to be part of the group from the government were two people
+from the Simonsen Vogt Wiik lawyer office, and three others I am not
+quite sure who was.  Økokrim had proposed to present two witnesses
+from The Motion Picture Association, but this was rejected because
+they did not speak Norwegian and it was a bit late to bring in a
+translator, but perhaps the two from MPA were present anyway.  All
+seven appeared to know each other.  Good to see the case is take
+seriously.&lt;/p&gt;
+
+&lt;p&gt;If you, like me, believe the courts should be involved before a DNS
+domain is hijacked by the government, or you believe the Popcorn Time
+technology have a lot of useful and legal applications, I suggest you
+too &lt;a href=&quot;http://www.nuug.no/dns-beslag-donasjon.shtml&quot;&gt;donate to
+the NUUG defense fund&lt;/a&gt;.  Both Bitcoin and bank transfer are
+available. If NUUG get more than we need for the legal action (very
+unlikely), the rest will be spend promoting free software, open
+standards and unix-like operating systems in Norway, so no matter what
+happens the money will be put to good use.&lt;/p&gt;
+
+&lt;p&gt;If you want to lean more about the case, I recommend you check out
+&lt;a href=&quot;https://www.nuug.no/news/tags/dns-domenebeslag/&quot;&gt;the blog
+posts from NUUG covering the case&lt;/a&gt;.  They cover the legal arguments
+on both sides.&lt;/p&gt;

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

+                <pubDate>Thu, 12 Jan 2017 09:40:00 +0100</pubDate>
+               <description>&lt;p&gt;I dag fikk jeg en skikkelig gladmelding.  Bakgrunnen er at før jul
+arrangerte Nasjonalbiblioteket
+&lt;a href=&quot;http://www.nb.no/Bibliotekutvikling/Kunnskapsorganisering/Nasjonalt-verksregister/Seminar-om-verksregister&quot;&gt;et
+seminar om sitt knakende gode tiltak «verksregister»&lt;/a&gt;.  Eneste
+måten å melde seg på dette seminaret var å sende personopplysninger
+til Google via Google Skjemaer.  Dette syntes jeg var tvilsom praksis,
+da det bør være mulig å delta på seminarer arrangert av det offentlige
+uten å måtte dele sine interesser, posisjon og andre
+personopplysninger med Google.  Jeg ba derfor om innsyn via
+&lt;a href=&quot;https://www.mimesbronn.no/&quot;&gt;Mimes brønn&lt;/a&gt; i
+&lt;a href=&quot;https://www.mimesbronn.no/request/personopplysninger_til_google_sk&quot;&gt;avtaler
+og vurderinger Nasjonalbiblioteket hadde rundt dette&lt;/a&gt;.
+Personopplysningsloven legger klare rammer for hva som må være på
+plass før en kan be tredjeparter, spesielt i utlandet, behandle
+personopplysninger på sine vegne, så det burde eksistere grundig
+dokumentasjon før noe slikt kan bli lovlig.  To jurister hos
+Nasjonalbiblioteket mente først dette var helt i orden, og at Googles
+standardavtale kunne brukes som databehandlingsavtale.  Det syntes jeg
+var merkelig, men har ikke hatt kapasitet til å følge opp saken før
+for to dager siden.&lt;/p&gt;
+
+&lt;p&gt;Gladnyheten i dag, som kom etter at jeg tipset Nasjonalbiblioteket
+om at Datatilsynet underkjente Googles standardavtaler som
+databehandleravtaler i 2011, er at Nasjonalbiblioteket har bestemt seg
+for å avslutte bruken av Googles Skjemaer/Apps og gå i dialog med DIFI
+for å finne bedre måter å håndtere påmeldinger i tråd med
+personopplysningsloven.  Det er fantastisk å se at av og til hjelper
+det å spørre hva i alle dager det offentlige holder på med.&lt;/p&gt;

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

+                <pubDate>Wed, 11 Jan 2017 06:50:00 +0100</pubDate>
+               <description>&lt;p&gt;Jeg leste med interesse en nyhetssak hos
+&lt;a href=&quot;http://www.digi.no/artikler/nav-avslorer-trygdemisbruk-ved-a-spore-ip-adresser/367394&quot;&gt;digi.no&lt;/a&gt;
+og
+&lt;a href=&quot;https://www.nrk.no/buskerud/trygdesvindlere-avslores-av-utenlandske-ip-adresser-1.13313461&quot;&gt;NRK&lt;/a&gt;
+om at det ikke bare er meg, men at også NAV bedriver geolokalisering
+av IP-adresser, og at det gjøres analyse av IP-adressene til de som
+sendes inn meldekort for å se om meldekortet sendes inn fra
+utenlandske IP-adresser.  Politiadvokat i Drammen, Hans Lyder Haare,
+er sitert i NRK på at «De to er jo blant annet avslørt av
+IP-adresser. At man ser at meldekortet kommer fra utlandet.»&lt;/p&gt;
+
+&lt;p&gt;Jeg synes det er fint at det blir bedre kjent at IP-adresser
+knyttes til enkeltpersoner og at innsamlet informasjon brukes til å
+stedsbestemme personer også av aktører her i Norge.  Jeg ser det som
+nok et argument for å bruke
+&lt;a href=&quot;https://www.torproject.org/&quot;&gt;Tor&lt;/a&gt; så mye som mulig for å
+gjøre gjøre IP-lokalisering vanskeligere, slik at en kan beskytte sin
+privatsfære og unngå å dele sin fysiske plassering med
+uvedkommede.&lt;/p&gt;
+
+&lt;P&gt;Men det er en ting som bekymrer meg rundt denne nyheten.  Jeg ble
+tipset (takk #nuug) om
+&lt;a href=&quot;https://www.nav.no/no/NAV+og+samfunn/Kontakt+NAV/Teknisk+brukerstotte/Snarveier/personvernerkl%C3%A6ring-for-arbeids-og-velferdsetaten&quot;&gt;NAVs
+personvernerklæring&lt;/a&gt;, som under punktet «Personvern og statistikk»
+lyder:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;
+
+&lt;p&gt;«Når du besøker nav.no, etterlater du deg elektroniske spor. Sporene
+dannes fordi din nettleser automatisk sender en rekke opplysninger til
+NAVs tjener (server-maskin) hver gang du ber om å få vist en side. Det
+er eksempelvis opplysninger om hvilken nettleser og -versjon du
+bruker, og din internettadresse (ip-adresse). For hver side som vises,
+lagres følgende opplysninger:&lt;/p&gt;
+
+&lt;ul&gt;
+&lt;li&gt;hvilken side du ser på&lt;/li&gt;
+&lt;li&gt;dato og tid&lt;/li&gt;
+&lt;li&gt;hvilken nettleser du bruker&lt;/li&gt;
+&lt;li&gt;din ip-adresse&lt;/li&gt;
+&lt;/ul&gt;
+
+&lt;p&gt;Ingen av opplysningene vil bli brukt til å identifisere
+enkeltpersoner. NAV bruker disse opplysningene til å generere en
+samlet statistikk som blant annet viser hvilke sider som er mest
+populære. Statistikken er et redskap til å forbedre våre
+tjenester.»&lt;/p&gt;
+
+&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;Jeg klarer ikke helt å se hvordan analyse av de besøkendes
+IP-adresser for å se hvem som sender inn meldekort via web fra en
+IP-adresse i utlandet kan gjøres uten å komme i strid med påstanden om
+at «ingen av opplysningene vil bli brukt til å identifisere
+enkeltpersoner».  Det virker dermed for meg som at NAV bryter sine
+egen personvernerklæring, hvilket
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Er_lover_brutt_n_r_personvernpolicy_ikke_stemmer_med_praksis_.html&quot;&gt;Datatilsynet
+fortalte meg i starten av desember antagelig er brudd på
+personopplysningsloven&lt;/a&gt;.
+
+&lt;p&gt;I tillegg er personvernerklæringen ganske misvisende i og med at
+NAVs nettsider ikke bare forsyner NAV med personopplysninger, men i
+tillegg ber brukernes nettleser kontakte fem andre nettjenere
+(script.hotjar.com, static.hotjar.com, vars.hotjar.com,
+www.google-analytics.com og www.googletagmanager.com), slik at
+personopplysninger blir gjort tilgjengelig for selskapene Hotjar og
+Google , og alle som kan lytte på trafikken på veien (som FRA, GCHQ og
+NSA).  Jeg klarer heller ikke se hvordan slikt spredning av
+personopplysninger kan være i tråd med kravene i
+personopplysningloven, eller i tråd med NAVs personvernerklæring.&lt;/p&gt;
+
+&lt;p&gt;Kanskje NAV bør ta en nøye titt på sin personvernerklæring?  Eller
+kanskje Datatilsynet bør gjøre det?&lt;/p&gt;

-The GPL is not magic pixie dust. It does not work by itself.&lt;br/&gt;
-
-The first step is to choose a

-code.&lt;br/&gt;
-
-The next step is, when someone fails to follow that copyleft license,
-&lt;b&gt;it must be enforced&lt;/b&gt;&lt;br/&gt;
-
-and its a simple fact of our modern society that such type of
-work&lt;br/&gt;
-
-is incredibly expensive to do and incredibly difficult to do.

-imply, public domain and permissively licensed software can lead to
-the production of more proprietary software as people discover useful
-software, extend it and or incorporate it into their hardware or
-software products.  Copyleft licenses such as the GNU GPL were created
-to close off this avenue to the production of proprietary software but
-such licenses are not enough.  With the ongoing adoption of Free
-Software by individuals and groups, inevitably the community&#39;s
-expectations of license compliance are violated, usually out of
-ignorance of the way Free Software works, but not always.  As Karen

-&lt;a href=&quot;http://faif.us/cast/2015/nov/24/0x57/&quot;&gt;episode 0x57&lt;/a&gt;,
-copyleft is nothing if no-one is willing and able to stand up in court
-to protect it.  The reality of today&#39;s world is that legal

-Freedom Conservancy&lt;/a&gt; (a tax-exempt charity) is the major defender
-of the Linux project, Debian and other groups against GPL violations.
-In March the SFC supported a

-by Christoph Hellwig&lt;/a&gt; against VMware for refusing to
-&lt;a href=&quot;https://sfconservancy.org/linux-compliance/vmware-lawsuit-faq.html&quot;&gt;comply
-with the GPL&lt;/a&gt; in relation to their use of parts of the Linux
-kernel.  Since then two of their sponsors pulled corporate funding and
-conferences
-&lt;a href=&quot;https://sfconservancy.org/blog/2015/nov/24/faif-carols-fundraiser/&quot;&gt;blocked
-or cancelled their talks&lt;/a&gt;.  As a result they have decided to rely
-less on corporate funding and more on the broad community of
-individuals who support Free Software and copyleft.  So the SFC has
-&lt;a href=&quot;https://sfconservancy.org/news/2015/nov/23/2015fundraiser/&quot;&gt;launched&lt;/a&gt;
-a &lt;a href=&quot;https://sfconservancy.org/supporter/&quot;&gt;campaign&lt;/a&gt; to create
-a community of folks who stand up for copyleft and the GPL by
-supporting their work on promoting and supporting copyleft and Free
-Software.&lt;/p&gt;

+               <description>&lt;p&gt;Did you ever wonder where the web trafic really flow to reach the
+web servers, and who own the network equipment it is flowing through?
+It is possible to get a glimpse of this from using traceroute, but it
+is hard to find all the details.  Many years ago, I wrote a system to
+map the Norwegian Internet (trying to figure out if our plans for a
+network game service would get low enough latency, and who we needed
+to talk to about setting up game servers close to the users.  Back
+then I used traceroute output from many locations (I asked my friends
+to run a script and send me their traceroute output) to create the
+graph and the map.  The output from traceroute typically look like
+this:
+
+&lt;p&gt;&lt;pre&gt;
+traceroute to www.stortinget.no (85.88.67.10), 30 hops max, 60 byte packets
+ 1  uio-gw10.uio.no (129.240.202.1)  0.447 ms  0.486 ms  0.621 ms
+ 2  uio-gw8.uio.no (129.240.24.229)  0.467 ms  0.578 ms  0.675 ms
+ 3  oslo-gw1.uninett.no (128.39.65.17)  0.385 ms  0.373 ms  0.358 ms
+ 4  te3-1-2.br1.fn3.as2116.net (193.156.90.3)  1.174 ms  1.172 ms  1.153 ms
+ 5  he16-1-1.cr1.san110.as2116.net (195.0.244.234)  2.627 ms he16-1-1.cr2.oslosda310.as2116.net (195.0.244.48)  3.172 ms he16-1-1.cr1.san110.as2116.net (195.0.244.234)  2.857 ms
+ 6  ae1.ar8.oslosda310.as2116.net (195.0.242.39)  0.662 ms  0.637 ms ae0.ar8.oslosda310.as2116.net (195.0.242.23)  0.622 ms
+ 7  89.191.10.146 (89.191.10.146)  0.931 ms  0.917 ms  0.955 ms
+ 8  * * *
+ 9  * * *
+[...]
+&lt;/pre&gt;&lt;/p&gt;
+
+&lt;p&gt;This show the DNS names and IP addresses of (at least some of the)
+network equipment involved in getting the data traffic from me to the
+www.stortinget.no server, and how long it took in milliseconds for a
+package to reach the equipment and return to me.  Three packages are
+sent, and some times the packages do not follow the same path.  This
+is shown for hop 5, where three different IP addresses replied to the
+traceroute request.&lt;/p&gt;
+
+&lt;p&gt;There are many ways to measure trace routes.  Other good traceroute
+implementations I use are traceroute (using ICMP packages) mtr (can do
+both ICMP, UDP and TCP) and scapy (python library with ICMP, UDP, TCP
+traceroute and a lot of other capabilities).  All of them are easily
+available in &lt;a href=&quot;https://www.debian.org/&quot;&gt;Debian&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;This time around, I wanted to know the geographic location of
+different route points, to visualize how visiting a web page spread
+information about the visit to a lot of servers around the globe.  The
+background is that a web site today often will ask the browser to get
+from many servers the parts (for example HTML, JSON, fonts,
+JavaScript, CSS, video) required to display the content.  This will
+leak information about the visit to those controlling these servers
+and anyone able to peek at the data traffic passing by (like your ISP,
+the ISPs backbone provider, FRA, GCHQ, NSA and others).&lt;/p&gt;
+
+&lt;p&gt;Lets pick an example, the Norwegian parliament web site
+www.stortinget.no.  It is read daily by all members of parliament and
+their staff, as well as political journalists, activits and many other
+citizens of Norway.  A visit to the www.stortinget.no web site will
+ask your browser to contact 8 other servers: ajax.googleapis.com,
+insights.hotjar.com, script.hotjar.com, static.hotjar.com,
+stats.g.doubleclick.net, www.google-analytics.com,
+www.googletagmanager.com and www.netigate.se.  I extracted this by
+asking &lt;a href=&quot;http://phantomjs.org/&quot;&gt;PhantomJS&lt;/a&gt; to visit the
+Stortinget web page and tell me all the URLs PhantomJS downloaded to
+render the page (in HAR format using
+&lt;a href=&quot;https://github.com/ariya/phantomjs/blob/master/examples/netsniff.js&quot;&gt;their
+netsniff example&lt;/a&gt;.  I am very grateful to Gorm for showing me how
+to do this).  My goal is to visualize network traces to all IP
+addresses behind these DNS names, do show where visitors personal
+information is spread when visiting the page.&lt;/p&gt;
+
+&lt;p align=&quot;center&quot;&gt;&lt;a href=&quot;www.stortinget.no-geoip.kml&quot;&gt;&lt;img
+src=&quot;http://people.skolelinux.org/pere/blog/images/2017-01-09-www.stortinget.no-geoip-small.png&quot; alt=&quot;map of combined traces for URLs used by www.stortinget.no using GeoIP&quot;/&gt;&lt;/a&gt;&lt;/p&gt;
+
+&lt;p&gt;When I had a look around for options, I could not find any good
+free software tools to do this, and decided I needed my own traceroute
+wrapper outputting KML based on locations looked up using GeoIP.  KML
+is easy to work with and easy to generate, and understood by several
+of the GIS tools I have available.  I got good help from by NUUG
+colleague Anders Einar with this, and the result can be seen in
+&lt;a href=&quot;https://github.com/petterreinholdtsen/kmltraceroute&quot;&gt;my
+kmltraceroute git repository&lt;/a&gt;.  Unfortunately, the quality of the
+free GeoIP databases I could find (and the for-pay databases my
+friends had access to) is not up to the task.  The IP addresses of
+central Internet infrastructure would typically be placed near the
+controlling companies main office, and not where the router is really
+located, as you can see from &lt;a href=&quot;www.stortinget.no-geoip.kml&quot;&gt;the
+KML file I created&lt;/a&gt; using the GeoLite City dataset from MaxMind.
+
+&lt;p align=&quot;center&quot;&gt;&lt;a href=&quot;http://people.skolelinux.org/pere/blog/images/2017-01-09-www.stortinget.no-scapy.svg&quot;&gt;&lt;img

+
+&lt;p&gt;I also had a look at the visual traceroute graph created by
+&lt;a href=&quot;http://www.secdev.org/projects/scapy/&quot;&gt;the scrapy project&lt;/a&gt;,
+showing IP network ownership (aka AS owner) for the IP address in
+question.
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/images/2017-01-09-www.stortinget.no-scapy.svg&quot;&gt;The
+graph display a lot of useful information about the traceroute in SVG
+format&lt;/a&gt;, and give a good indication on who control the network
+equipment involved, but it do not include geolocation.  This graph
+make it possible to see the information is made available at least for
+UNINETT, Catchcom, Stortinget, Nordunet, Google, Amazon, Telia, Level
+3 Communications and NetDNA.&lt;/p&gt;
+
+&lt;p align=&quot;center&quot;&gt;&lt;a href=&quot;https://geotraceroute.com/index.php?node=4&amp;host=www.stortinget.no&quot;&gt;&lt;img
+src=&quot;http://people.skolelinux.org/pere/blog/images/2017-01-09-www.stortinget.no-geotraceroute-small.png&quot; alt=&quot;example geotraceroute view for www.stortinget.no&quot;/&gt;&lt;/a&gt;&lt;/p&gt;
+
+&lt;p&gt;In the process, I came across the
+&lt;a href=&quot;https://geotraceroute.com/&quot;&gt;web service GeoTraceroute&lt;/a&gt; by
+Salim Gasmi.  Its methology of combining guesses based on DNS names,
+various location databases and finally use latecy times to rule out
+candidate locations seemed to do a very good job of guessing correct
+geolocation.  But it could only do one trace at the time, did not have
+a sensor in Norway and did not make the geolocations easily available
+for postprocessing.  So I contacted the developer and asked if he
+would be willing to share the code (he refused until he had time to
+clean it up), but he was interested in providing the geolocations in a
+machine readable format, and willing to set up a sensor in Norway.  So
+since yesterday, it is possible to run traces from Norway in this
+service thanks to a sensor node set up by
+&lt;a href=&quot;https://www.nuug.no/&quot;&gt;the NUUG assosiation&lt;/a&gt;, and get the
+trace in KML format for further processing.&lt;/p&gt;
+
+&lt;p align=&quot;center&quot;&gt;&lt;a href=&quot;http://people.skolelinux.org/pere/blog/images/2017-01-09-www.stortinget.no-geotraceroute-kml-join.kml&quot;&gt;&lt;img

+
+&lt;p&gt;Here we can see a lot of trafic passes Sweden on its way to
+Denmark, Germany, Holland and Ireland.  Plenty of places where the
+Snowden confirmations verified the traffic is read by various actors
+without your best interest as their top priority.&lt;/p&gt;
+
+&lt;p&gt;Combining KML files is trivial using a text editor, so I could loop
+over all the hosts behind the urls imported by www.stortinget.no and
+ask for the KML file from GeoTraceroute, and create a combined KML
+file with all the traces (unfortunately only one of the IP addresses
+behind the DNS name is traced this time.  To get them all, one would
+have to request traces using IP number instead of DNS names from
+GeoTraceroute).  That might be the next step in this project.&lt;/p&gt;
+
+&lt;p&gt;Armed with these tools, I find it a lot easier to figure out where
+the IP traffic moves and who control the boxes involved in moving it.
+And every time the link crosses for example the Swedish border, we can
+be sure Swedish Signal Intelligence (FRA) is listening, as GCHQ do in
+Britain and NSA in USA and cables around the globe.  (Hm, what should
+we tell them? :) Keep that in mind if you ever send anything
+unencrypted over the Internet.&lt;/p&gt;
+
+&lt;p&gt;PS: KML files are drawn using
+&lt;a href=&quot;http://ivanrublev.me/kml/&quot;&gt;the KML viewer from Ivan
+Rublev&lt;a/&gt;, as it was less cluttered than the local Linux application
+Marble.  There are heaps of other options too.&lt;/p&gt;
