-               <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&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
-hosted weblate project page&lt;/a&gt;, and get in touch using
-&lt;a href=&quot;http://lists.alioth.debian.org/mailman/listinfo/debian-handbook-translators&quot;&gt;the
-translators mailing list&lt;/a&gt;.  Please also check out
-&lt;a href=&quot;https://debian-handbook.info/contribute/&quot;&gt;the instructions for
-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;p&gt;Our goal is still to make the Norwegian book available in paper as well as
-electronic form.&lt;/p&gt;

+               <description>Når jeg holder på med ulike prosjekter, så trenger jeg stadig ulike
+skruer.  Det siste prosjektet jeg holder på med er å lage
+&lt;a href=&quot;https://www.thingiverse.com/thing:676916&quot;&gt;en boks til en
+HDMI-touch-skjerm&lt;/a&gt; som skal brukes med Raspberry Pi.  Boksen settes
+sammen med skruer og bolter, og jeg har vært i tvil om hvor jeg kan
+få tak i de riktige skruene.  Clas Ohlson og Jernia i nærheten har
+sjelden hatt det jeg trenger.  Men her om dagen fikk jeg et fantastisk
+tips for oss som bor i Oslo.
+&lt;a href=&quot;http://www.zachskruer.no/&quot;&gt;Zachariassen Jernvare AS&lt;/a&gt; i
+&lt;a href=&quot;http://www.openstreetmap.org/?mlat=59.93421&amp;mlon=10.76795#map=19/59.93421/10.76795&quot;&gt;Hegermannsgate
+23A på Torshov&lt;/a&gt; har et fantastisk utvalg, og åpent mellom 09:00 og
+17:00.  De selger skruer, muttere, bolter, skiver etc i løs vekt, og
+så langt har jeg fått alt jeg har lett etter.  De har i tillegg det
+meste av annen jernvare, som verktøy, lamper, ledninger, etc.  Jeg
+håper de har nok kunder til å holde det gående lenge, da dette er en
+butikk jeg kommer til å besøke ofte.  Butikken er et funn å ha i
+nabolaget for oss som liker å bygge litt selv. :)&lt;/p&gt;

-               <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;Every mobile phone announce its existence over radio to the nearby
+mobile cell towers.  And this radio chatter is available for anyone
+with a radio receiver capable of receiving them.  Details about the
+mobile phones with very good accuracy is of course collected by the
+phone companies, but this is not the topic of this blog post.  The
+mobile phone radio chatter make it possible to figure out when a cell
+phone is nearby, as it include the SIM card ID (IMSI).  By paying
+attention over time, one can see when a phone arrive and when it leave
+an area.  I believe it would be nice to make this information more
+available to the general public, to make more people aware of how
+their phones are announcing their whereabouts to anyone that care to
+listen.&lt;/p&gt;
+
+&lt;p&gt;I am very happy to report that we managed to get something
+visualizing this information up and running for
+&lt;a href=&quot;http://norwaymakers.org/osf17&quot;&gt;Oslo Skaperfestival 2017&lt;/a&gt;
+(Oslo Makers Festival) taking place today and tomorrow at Deichmanske
+library.  The solution is based on the
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Easier_recipe_to_observe_the_cell_phones_around_you.html&quot;&gt;simple
+recipe for listening to GSM chatter&lt;/a&gt; I posted a few days ago, and
+will show up at the stand of &lt;a href=&quot;http://sonen.ifi.uio.no/&quot;&gt;Åpen
+Sone from the Computer Science department of the University of
+Oslo&lt;/a&gt;.  The presentation will show the nearby mobile phones (aka
+IMSIs) as dots in a web browser graph, with lines to the dot
+representing mobile base station it is talking to. It was working in
+the lab yesterday, and was moved into place this morning.&lt;/p&gt;
+
+&lt;p&gt;We set up a fairly powerful desktop machine using Debian
+Buster/Testing with several (five, I believe) RTL2838 DVB-T receivers
+connected and visualize the visible cell phone towers using an
+&lt;a href=&quot;https://github.com/marlow925/hopglass&quot;&gt;English version of
+Hopglass&lt;/a&gt;.  A fairly powerfull machine is needed as the
+grgsm_livemon_headless processes from
+&lt;a href=&quot;https://tracker.debian.org/pkg/gr-gsm&quot;&gt;gr-gsm&lt;/a&gt; converting
+the radio signal to data packages is quite CPU intensive.&lt;/p&gt;
+                                       
+&lt;p&gt;The frequencies to listen to, are identified using a slightly
+patched scan-and-livemon (to set the --args values for each receiver),
+and the Hopglass data is generated using the
+&lt;a href=&quot;https://github.com/petterreinholdtsen/IMSI-catcher/tree/meshviewer-output&quot;&gt;patches
+in my meshviewer-output branch&lt;/a&gt;.  For some reason we could not get
+more than four SDRs working.  There is also a geographical map trying
+to show the location of the base stations, but I believe their
+coordinates are hardcoded to some random location in Germany, I
+believe.  The code should be replaced with code to look up location in
+a text file, a sqlite database or one of the online databases
+mentioned in
+&lt;a href=&quot;https://github.com/Oros42/IMSI-catcher/issues/14&quot;&gt;the github
+issue for the topic&lt;/a&gt;.
+
+&lt;p&gt;If this sound interesting, visit the stand at the festival!&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;

+               <description>&lt;p&gt;A little more than a month ago I wrote
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Simpler_recipe_on_how_to_make_a_simple__7_IMSI_Catcher_using_Debian.html&quot;&gt;how
+to observe the SIM card ID (aka IMSI number) of mobile phones talking
+to nearby mobile phone base stations using Debian GNU/Linux and a
+cheap USB software defined radio&lt;/a&gt;, and thus being able to pinpoint
+the location of people and equipment (like cars and trains) with an
+accuracy of a few kilometer.  Since then we have worked to make the
+procedure even simpler, and it is now possible to do this without any
+manual frequency tuning and without building your own packages.&lt;/p&gt;
+
+&lt;p&gt;The &lt;a href=&quot;https://tracker.debian.org/pkg/gr-gsm&quot;&gt;gr-gsm&lt;/a&gt;
+package is now included in Debian testing and unstable, and the
+IMSI-catcher code no longer require root access to fetch and decode
+the GSM data collected using gr-gsm.&lt;/p&gt;
+
+&lt;p&gt;Here is an updated recipe, using packages built by Debian and a git
+clone of two python scripts:&lt;/p&gt;
+
+&lt;ol&gt;
+
+&lt;li&gt;Start with a Debian machine running the Buster version (aka
+  testing).&lt;/li&gt;
+
+&lt;li&gt;Run &#39;&lt;tt&gt;apt install gr-gsm python-numpy python-scipy
+  python-scapy&lt;/tt&gt;&#39; as root to install required packages.&lt;/li&gt;
+
+&lt;li&gt;Fetch the code decoding GSM packages using &#39;&lt;tt&gt;git clone
+  github.com/Oros42/IMSI-catcher.git&lt;/tt&gt;&#39;.&lt;/li&gt;
+
+&lt;li&gt;Insert USB software defined radio supported by GNU Radio.&lt;/li&gt;
+
+&lt;li&gt;Enter the IMSI-catcher directory and run &#39;&lt;tt&gt;python
+  scan-and-livemon&lt;/tt&gt;&#39; to locate the frequency of nearby base
+  stations and start listening for GSM packages on one of them.&lt;/li&gt;
+
+&lt;li&gt;Enter the IMSI-catcher directory and run &#39;&lt;tt&gt;python
+  simple_IMSI-catcher.py&lt;/tt&gt;&#39; to display the collected information.&lt;/li&gt;
+
+&lt;/ol&gt;
+
+&lt;p&gt;Note, due to a bug somewhere the scan-and-livemon program (actually
+&lt;a href=&quot;https://github.com/ptrkrysik/gr-gsm/issues/336&quot;&gt;its underlying
+program grgsm_scanner&lt;/a&gt;) do not work with the HackRF radio.  It does
+work with RTL 8232 and other similar USB radio receivers you can get
+very cheaply
+(&lt;a href=&quot;https://www.ebay.com/sch/items/?_nkw=rtl+2832&quot;&gt;for example
+from ebay&lt;/a&gt;), so for now the solution is to scan using the RTL radio
+and only use HackRF for fetching GSM data.&lt;/p&gt;
+
+&lt;p&gt;As far as I can tell, a cell phone only show up on one of the
+frequencies at the time, so if you are going to track and count every
+cell phone around you, you need to listen to all the frequencies used.
+To listen to several frequencies, use the --numrecv argument to
+scan-and-livemon to use several receivers.  Further, I am not sure if
+phones using 3G or 4G will show as talking GSM to base stations, so
+this approach might not see all phones around you.  I typically see
+0-400 IMSI numbers an hour when looking around where I live.&lt;/p&gt;
+
+&lt;p&gt;I&#39;ve tried to run the scanner on a
+&lt;a href=&quot;https://wiki.debian.org/RaspberryPi&quot;&gt;Raspberry Pi 2 and 3
+running Debian Buster&lt;/a&gt;, but the grgsm_livemon_headless process seem
+to be too CPU intensive to keep up.  When GNU Radio print &#39;O&#39; to
+stdout, I am told there it is caused by a buffer overflow between the
+radio and GNU Radio, caused by the program being unable to read the
+GSM data fast enough.  If you see a stream of &#39;O&#39;s from the terminal
+where you started scan-and-livemon, you need a give the process more
+CPU power.  Perhaps someone are able to optimize the code to a point
+where it become possible to set up RPi3 based GSM sniffers?  I tried
+using Raspbian instead of Debian, but there seem to be something wrong
+with GNU Radio on raspbian, causing glibc to abort().&lt;/p&gt;

-               <description>&lt;p&gt;For mange år siden leste jeg en klassisk tekst som gjorde såpass
-inntrykk på meg at jeg husker den fortsatt, flere år senere, og bruker
-argumentene fra den stadig vekk.  Teksten var «The Relativity of
-Wrong» som Isaac Asimov publiserte i Skeptical Inquirer i 1989.  Den
-gir litt perspektiv rundt formidlingen av vitenskapelige resultater.
-Jeg har hatt lyst til å kunne dele den også med folk som ikke
-behersker engelsk så godt, som barn og noen av mine eldre slektninger,
-og har savnet å ha den tilgjengelig på norsk.  For to uker siden tok
-jeg meg sammen og kontaktet Asbjørn Dyrendal i foreningen Skepsis om
-de var interessert i å publisere en norsk utgave på bloggen sin, og da
-han var positiv tok jeg kontakt med Skeptical Inquirer og spurte om
-det var greit for dem.  I løpet av noen dager fikk vi tilbakemelding

+               <description>&lt;p&gt;For noen dager siden publiserte Jon Wessel-Aas en bloggpost om
+«&lt;a href=&quot;http://www.uhuru.biz/?p=1821&quot;&gt;Konklusjonen om datalagring som
+EU-kommisjonen ikke ville at vi skulle få se&lt;/a&gt;».  Det er en
+interessant gjennomgang av EU-domstolens syn på snurpenotovervåkning
+av befolkningen, som er klar på at det er i strid med
+EU-lovgivingen.&lt;/p&gt;
+
+&lt;p&gt;Valgkampen går for fullt i Norge, og om noen få dager er siste
+frist for å avgi stemme.  En ting er sikkert, Høyre og Arbeiderpartiet
+får ikke min stemme
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Datalagringsdirektivet_gj_r_at_Oslo_H_yre_og_Arbeiderparti_ikke_f_r_min_stemme_i__r.html&quot;&gt;denne
+gangen heller&lt;/a&gt;.  Jeg har ikke glemt at de tvang igjennom loven som
+skulle pålegge alle data- og teletjenesteleverandører å overvåke alle
+sine kunder.  En lov som er vedtatt, og aldri opphevet igjen.&lt;/p&gt;
+
+&lt;p&gt;Det er tydelig fra diskusjonen rundt grenseløs digital overvåkning
+(eller &quot;Digital Grenseforsvar&quot; som det kalles i Orvellisk nytale) at
+hverken Høyre og Arbeiderpartiet har noen prinsipielle sperrer mot å
+overvåke hele befolkningen, og diskusjonen så langt tyder på at flere
+av de andre partiene heller ikke har det. Mange av
+&lt;a href=&quot;https://data.holderdeord.no/votes/1301946411e&quot;&gt;de som stemte
+for Datalagringsdirektivet i Stortinget&lt;/a&gt; (64 fra Arbeiderpartiet,
+25 fra Høyre) er fortsatt aktive og argumenterer fortsatt for å radere
+vekk mer av innbyggernes privatsfære.&lt;/p&gt;
+
+&lt;p&gt;Når myndighetene demonstrerer sin mistillit til folket, tror jeg
+folket selv bør legge litt innsats i å verne sitt privatliv, ved å ta
+i bruk ende-til-ende-kryptert kommunikasjon med sine kjente og kjære,
+og begrense hvor mye privat informasjon som deles med uvedkommende.
+Det er jo ingenting som tyder på at myndighetene kommer til å være vår
+privatsfære.
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/How_to_talk_with_your_loved_ones_in_private.html&quot;&gt;Det
+er mange muligheter&lt;/a&gt;.  Selv har jeg litt sans for
+&lt;a href=&quot;https://ring.cx/&quot;&gt;Ring&lt;/a&gt;, som er basert på p2p-teknologi
+uten sentral kontroll, er fri programvare, og støtter meldinger, tale
+og video.  Systemet er tilgjengelig ut av boksen fra
+&lt;a href=&quot;https://tracker.debian.org/pkg/ring&quot;&gt;Debian&lt;/a&gt; og
+&lt;a href=&quot;https://launchpad.net/ubuntu/+source/ring&quot;&gt;Ubuntu&lt;/a&gt;, og det
+finnes pakker for Android, MacOSX og Windows.  Foreløpig er det få
+brukere med Ring, slik at jeg også bruker
+&lt;a href=&quot;https://signal.org/&quot;&gt;Signal&lt;/a&gt; som nettleserutvidelse.&lt;/p&gt;

-               <description>&lt;p&gt;Did you know there is a TV channel broadcasting talks from DebConf
-16 across an entire country?  Or that there is a TV channel
-broadcasting talks by or about
-&lt;a href=&quot;http://beta.frikanalen.no/video/625529/&quot;&gt;Linus Torvalds&lt;/a&gt;,
-&lt;a href=&quot;http://beta.frikanalen.no/video/625599/&quot;&gt;Tor&lt;/a&gt;,
-&lt;a href=&quot;http://beta.frikanalen.no/video/624019/&quot;&gt;OpenID&lt;/A&gt;,
-&lt;a href=&quot;http://beta.frikanalen.no/video/625624/&quot;&gt;Common Lisp&lt;/a&gt;,
-&lt;a href=&quot;http://beta.frikanalen.no/video/625446/&quot;&gt;Civic Tech&lt;/a&gt;,
-&lt;a href=&quot;http://beta.frikanalen.no/video/625090/&quot;&gt;EFF founder John Barlow&lt;/a&gt;,
-&lt;a href=&quot;http://beta.frikanalen.no/video/625432/&quot;&gt;how to make 3D
-printer electronics&lt;/a&gt; and many more fascinating topics?  It works
-using only free software (all of it
-&lt;a href=&quot;http://github.com/Frikanalen&quot;&gt;available from Github&lt;/a&gt;), and
-is administrated using a web browser and a web API.&lt;/p&gt;
-
-&lt;p&gt;The TV channel is the Norwegian open channel
-&lt;a href=&quot;http://www.frikanalen.no/&quot;&gt;Frikanalen&lt;/a&gt;, and I am involved
-via &lt;a href=&quot;https://www.nuug.no/&quot;&gt;the NUUG member association&lt;/a&gt; in
-running and developing the software for the channel.  The channel is
-organised as a member organisation where its members can upload and
-broadcast what they want (think of it as Youtube for national
-broadcasting television).  Individuals can broadcast too.  The time
-slots are handled on a first come, first serve basis.  Because the
-channel have almost no viewers and very few active members, we can
-experiment with TV technology without too much flack when we make
-mistakes.  And thanks to the few active members, most of the slots on
-the schedule are free.  I see this as an opportunity to spread
-knowledge about technology and free software, and have a script I run
-regularly to fill up all the open slots the next few days with
-technology related video.  The end result is a channel I like to
-describe as Techno TV - filled with interesting talks and
-presentations.&lt;/p&gt;
-
-&lt;p&gt;It is available on channel 50 on the Norwegian national digital TV
-network (RiksTV).  It is also available as a multicast stream on
-Uninett.  And finally, it is available as
-&lt;a href=&quot;http://beta.frikanalen.no/&quot;&gt;a WebM unicast stream&lt;/a&gt; from
-Frikanalen and NUUG.  Check it out. :)&lt;/p&gt;

+                <pubDate>Wed, 9 Aug 2017 23:59:00 +0200</pubDate>
+               <description>&lt;p&gt;On friday, I came across an interesting article in the Norwegian
+web based ICT news magazine digi.no on
+&lt;a href=&quot;https://www.digi.no/artikler/sikkerhetsforsker-lagde-enkel-imsi-catcher-for-60-kroner-na-kan-mobiler-kartlegges-av-alle/398588&quot;&gt;how
+to collect the IMSI numbers of nearby cell phones&lt;/a&gt; using the cheap
+DVB-T software defined radios.  The article refered to instructions
+and &lt;a href=&quot;https://www.youtube.com/watch?v=UjwgNd_as30&quot;&gt;a recipe by
+Keld Norman on Youtube on how to make a simple $7 IMSI Catcher&lt;/a&gt;, and I decided to test them out.&lt;/p&gt;
+
+&lt;p&gt;The instructions said to use Ubuntu, install pip using apt (to
+bypass apt), use pip to install pybombs (to bypass both apt and pip),
+and the ask pybombs to fetch and build everything you need from
+scratch.  I wanted to see if I could do the same on the most recent
+Debian packages, but this did not work because pybombs tried to build
+stuff that no longer build with the most recent openssl library or
+some other version skew problem.  While trying to get this recipe
+working, I learned that the apt-&gt;pip-&gt;pybombs route was a long detour,
+and the only piece of software dependency missing in Debian was the
+gr-gsm package.  I also found out that the lead upstream developer of
+gr-gsm (the name stand for GNU Radio GSM) project already had a set of
+Debian packages provided in an Ubuntu PPA repository.  All I needed to
+do was to dget the Debian source package and built it.&lt;/p&gt;
+
+&lt;p&gt;The IMSI collector is a python script listening for packages on the
+loopback network device and printing to the terminal some specific GSM
+packages with IMSI numbers in them.  The code is fairly short and easy
+to understand.  The reason this work is because gr-gsm include a tool
+to read GSM data from a software defined radio like a DVB-T USB stick
+and other software defined radios, decode them and inject them into a
+network device on your Linux machine (using the loopback device by
+default).  This proved to work just fine, and I&#39;ve been testing the
+collector for a few days now.&lt;/p&gt;
+
+&lt;p&gt;The updated and simpler recipe is thus to&lt;/p&gt;
+
+&lt;ol&gt;
+
+&lt;li&gt;start with a Debian machine running Stretch or newer,&lt;/li&gt;
+
+&lt;li&gt;build and install the gr-gsm package available from
+&lt;a href=&quot;http://ppa.launchpad.net/ptrkrysik/gr-gsm/ubuntu/pool/main/g/gr-gsm/&quot;&gt;http://ppa.launchpad.net/ptrkrysik/gr-gsm/ubuntu/pool/main/g/gr-gsm/&lt;/a&gt;,&lt;/li&gt;
+
+&lt;li&gt;clone the git repostory from &lt;a href=&quot;https://github.com/Oros42/IMSI-catcher&quot;&gt;https://github.com/Oros42/IMSI-catcher&lt;/a&gt;,&lt;/li&gt;
+
+&lt;li&gt;run grgsm_livemon and adjust the frequency until the terminal
+where it was started is filled with a stream of text (meaning you
+found a GSM station).&lt;/li&gt;
+
+&lt;li&gt;go into the IMSI-catcher directory and run &#39;sudo python simple_IMSI-catcher.py&#39; to extract the IMSI numbers.&lt;/li&gt;
+
+&lt;/ol&gt;
+
+&lt;p&gt;To make it even easier in the future to get this sniffer up and
+running, I decided to package
+&lt;a href=&quot;https://github.com/ptrkrysik/gr-gsm/&quot;&gt;the gr-gsm project&lt;/a&gt;
+for Debian (&lt;a href=&quot;https://bugs.debian.org/871055&quot;&gt;WNPP
+#871055&lt;/a&gt;), and the package was uploaded into the NEW queue today.
+Luckily the gnuradio maintainer has promised to help me, as I do not
+know much about gnuradio stuff yet.&lt;/p&gt;
+
+&lt;p&gt;I doubt this &quot;IMSI cacher&quot; is anywhere near as powerfull as
+commercial tools like
+&lt;a href=&quot;https://www.thespyphone.com/portable-imsi-imei-catcher/&quot;&gt;The
+Spy Phone Portable IMSI / IMEI Catcher&lt;/a&gt; or the
+&lt;a href=&quot;https://en.wikipedia.org/wiki/Stingray_phone_tracker&quot;&gt;Harris
+Stingray&lt;/a&gt;, but I hope the existance of cheap alternatives can make
+more people realise how their whereabouts when carrying a cell phone
+is easily tracked.  Seeing the data flow on the screen, realizing that
+I live close to a police station and knowing that the police is also
+wearing cell phones, I wonder how hard it would be for criminals to
+track the position of the police officers to discover when there are
+police near by, or for foreign military forces to track the location
+of the Norwegian military forces, or for anyone to track the location
+of government officials...&lt;/p&gt;
+
+&lt;p&gt;It is worth noting that the data reported by the IMSI-catcher
+script mentioned above is only a fraction of the data broadcasted on
+the GSM network.  It will only collect one frequency at the time,
+while a typical phone will be using several frequencies, and not all
+phones will be using the frequencies tracked by the grgsm_livemod
+program.  Also, there is a lot of radio chatter being ignored by the
+simple_IMSI-catcher script, which would be collected by extending the
+parser code.  I wonder if gr-gsm can be set up to listen to more than
+one frequency?&lt;/p&gt;

-               <title>Unlocking HTC Desire HD on Linux using unruu and fastboot</title>
-               <link>http://people.skolelinux.org/pere/blog/Unlocking_HTC_Desire_HD_on_Linux_using_unruu_and_fastboot.html</link>
-               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Unlocking_HTC_Desire_HD_on_Linux_using_unruu_and_fastboot.html</guid>
-                <pubDate>Thu, 7 Jul 2016 11:30:00 +0200</pubDate>
-               <description>&lt;p&gt;Yesterday, I tried to unlock a HTC Desire HD phone, and it proved
-to be a slight challenge.  Here is the recipe if I ever need to do it
-again.  It all started by me wanting to try the recipe to set up
-&lt;a href=&quot;https://blog.torproject.org/blog/mission-impossible-hardening-android-security-and-privacy&quot;&gt;an
-hardened Android installation&lt;/a&gt; from the Tor project blog on a
-device I had access to.  It is a old mobile phone with a broken
-microphone The initial idea had been to just
-&lt;a href=&quot;http://wiki.cyanogenmod.org/w/Install_CM_for_ace&quot;&gt;install
-CyanogenMod on it&lt;/a&gt;, but did not quite find time to start on it
-until a few days ago.&lt;/p&gt;
-
-&lt;p&gt;The unlock process is supposed to be simple: (1) Boot into the boot
-loader (press volume down and power at the same time), (2) select
-&#39;fastboot&#39; before (3) connecting the device via USB to a Linux
-machine, (4) request the device identifier token by running &#39;fastboot
-oem get_identifier_token&#39;, (5) request the device unlocking key using
-the &lt;a href=&quot;http://www.htcdev.com/bootloader/&quot;&gt;HTC developer web
-site&lt;/a&gt; and unlock the phone using the key file emailed to you.&lt;/p&gt;
-
-&lt;p&gt;Unfortunately, this only work fi you have hboot version 2.00.0029
-or newer, and the device I was working on had 2.00.0027.  This
-apparently can be easily fixed by downloading a Windows program and
-running it on your Windows machine, if you accept the terms Microsoft
-require you to accept to use Windows - which I do not.  So I had to
-come up with a different approach.  I got a lot of help from AndyCap
-on #nuug, and would not have been able to get this working without
-him.&lt;/p&gt;
-
-&lt;p&gt;First I needed to extract the hboot firmware from
-&lt;a href=&quot;http://www.htcdev.com/ruu/PD9810000_Ace_Sense30_S_hboot_2.00.0029.exe&quot;&gt;the
-windows binary for HTC Desire HD&lt;/a&gt; downloaded as &#39;the RUU&#39; from HTC.
-For this there is is &lt;a href=&quot;https://github.com/kmdm/unruu/&quot;&gt;a github
-project named unruu&lt;/a&gt; using libunshield.  The unshield tool did not
-recognise the file format, but unruu worked and extracted rom.zip,
-containing the new hboot firmware and a text file describing which
-devices it would work for.&lt;/p&gt;
-
-&lt;p&gt;Next, I needed to get the new firmware into the device.  For this I
-followed some instructions
-&lt;a href=&quot;http://www.htc1guru.com/2013/09/new-ruu-zips-posted/&quot;&gt;available
-from HTC1Guru.com&lt;/a&gt;, and ran these commands as root on a Linux
-machine with Debian testing:&lt;/p&gt;
-
-&lt;p&gt;&lt;pre&gt;
-adb reboot-bootloader
-fastboot oem rebootRUU
-fastboot flash zip rom.zip
-fastboot flash zip rom.zip
-fastboot reboot
-&lt;/pre&gt;&lt;/p&gt;
-
-&lt;p&gt;The flash command apparently need to be done twice to take effect,
-as the first is just preparations and the second one do the flashing.
-The adb command is just to get to the boot loader menu, so turning the
-device on while holding volume down and the power button should work
-too.&lt;/p&gt;
-
-&lt;p&gt;With the new hboot version in place I could start following the
-instructions on the HTC developer web site.  I got the device token
-like this:&lt;/p&gt;
-
-&lt;p&gt;&lt;pre&gt;
-fastboot oem get_identifier_token 2&gt;&amp;1 | sed &#39;s/(bootloader) //&#39;
-&lt;/pre&gt;
-
-&lt;p&gt;And once I got the unlock code via email, I could use it like
-this:&lt;/p&gt;
-
-&lt;p&gt;&lt;pre&gt;
-fastboot flash unlocktoken Unlock_code.bin
-&lt;/pre&gt;&lt;/p&gt;
-
-&lt;p&gt;And with that final step in place, the phone was unlocked and I
-could start stuffing the software of my own choosing into the device.
-So far I only inserted a replacement recovery image to wipe the phone
-before I start.  We will see what happen next.  Perhaps I should
-install &lt;a href=&quot;https://www.debian.org/&quot;&gt;Debian&lt;/a&gt; on it. :)&lt;/p&gt;

+&lt;a href=&quot;https://debian-handbook.info/get/#norwegian&quot;&gt;is available
+from lulu.com&lt;/a&gt;.  If you buy it quickly, you save 25% on the list

+&lt;a href=&quot;https://debian-handbook.info/browse/nb-NO/stable/&quot;&gt;read online
+as a web page&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;This is the second book I publish (the first was the book

-                <pubDate>Sun, 3 Jul 2016 14:20:00 +0200</pubDate>
-               <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
-
-&lt;pre&gt;
-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;p&gt;The first part is changing the servers, and the second is updating
-an expiration timestamp.  This timestamp need to be updated regularly.
-It is set 90 days in the future by the build process (Gruntfile.js).
-The value is seconds since 1970 times 1000, as far as I can tell.&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;

+               <description>&lt;p&gt;Jeg kom over teksten
+«&lt;a href=&quot;https://freedom-to-tinker.com/2017/06/21/killing-car-privacy-by-federal-mandate/&quot;&gt;Killing
+car privacy by federal mandate&lt;/a&gt;» av Leonid Reyzin på Freedom to
+Tinker i dag, og det gleder meg å se en god gjennomgang om hvorfor det
+er et urimelig inngrep i privatsfæren å la alle biler kringkaste sin
+posisjon og bevegelse via radio.  Det omtalte forslaget basert på
+Dedicated Short Range Communication (DSRC) kalles Basic Safety Message
+(BSM) i USA og Cooperative Awareness Message (CAM) i Europa, og det
+norske Vegvesenet er en av de som ser ut til å kunne tenke seg å
+pålegge alle biler å fjerne nok en bit av innbyggernes privatsfære.
+Anbefaler alle å lese det som står der.
+
+&lt;p&gt;Mens jeg tittet litt på DSRC på biler i Norge kom jeg over et sitat
+jeg synes er illustrativt for hvordan det offentlige Norge håndterer
+problemstillinger rundt innbyggernes privatsfære i SINTEF-rapporten
+«&lt;a href=&quot;https://www.sintef.no/publikasjoner/publikasjon/Download/?pubid=SINTEF+A23933&quot;&gt;Informasjonssikkerhet
+i AutoPASS-brikker&lt;/a&gt;» av Trond Foss:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;
+«Rapporten ser ikke på informasjonssikkerhet knyttet til personlig
+  integritet.»
+&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;Så enkelt kan det tydeligvis gjøres når en vurderer
+informasjonssikkerheten.  Det holder vel at folkene på toppen kan si
+at «Personvernet er ivaretatt», som jo er den populære intetsigende
+frasen som gjør at mange tror enkeltindividers integritet tas vare på.
+Sitatet fikk meg til å undres på hvor ofte samme tilnærming, å bare se
+bort fra behovet for personlig itegritet, blir valgt når en velger å
+legge til rette for nok et inngrep i privatsfæren til personer i
+Norge.  Det er jo sjelden det får reaksjoner.  Historien om
+reaksjonene på Helse Sør-Østs tjenesteutsetting er jo sørgelig nok et
+unntak og toppen av isfjellet, desverre.  Tror jeg fortsatt takker nei
+til både AutoPASS og holder meg så langt unna det norske helsevesenet
+som jeg kan, inntil de har demonstrert og dokumentert at de verdsetter
+individets privatsfære og personlige integritet høyere enn kortsiktig
+gevist og samfunnsnytte.&lt;/p&gt;

-               <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;a href=&quot;https://www.arkivverket.no/forvaltning-og-utvikling/regelverk-og-standarder/noark-standarden&quot;&gt;Noark
+5 standard&lt;/a&gt; for government archives.&lt;/em&gt;&lt;/p&gt;
+
+&lt;p&gt;I&#39;ve been wondering a bit lately how trusted timestamps could be
+stored in Noark 5.
+&lt;a href=&quot;https://en.wikipedia.org/wiki/Trusted_timestamping&quot;&gt;Trusted
+timestamps&lt;/a&gt; can be used to verify that some information
+(document/file/checksum/metadata) have not been changed since a
+specific time in the past.  This is useful to verify the integrity of
+the documents in the archive.&lt;/p&gt;
+
+&lt;p&gt;Then it occured to me, perhaps the trusted timestamps could be
+stored as dokument variants (ie dokumentobjekt referered to from
+dokumentbeskrivelse) with the filename set to the hash it is
+stamping?&lt;/p&gt;
+
+&lt;p&gt;Given a &quot;dokumentbeskrivelse&quot; with an associated &quot;dokumentobjekt&quot;,
+a new dokumentobjekt is associated with &quot;dokumentbeskrivelse&quot; with the
+same attributes as the stamped dokumentobjekt except these
+attributes:&lt;/p&gt;
+
+&lt;ul&gt;
+
+&lt;li&gt;format -&gt; &quot;RFC3161&quot;
+&lt;li&gt;mimeType -&gt; &quot;application/timestamp-reply&quot;
+&lt;li&gt;formatDetaljer -&gt; &quot;&amp;lt;source URL for timestamp service&amp;gt;&quot;
+&lt;li&gt;filenavn -&gt; &quot;&amp;lt;sjekksum&amp;gt;.tsr&quot;
+
+&lt;/ul&gt;
+
+&lt;p&gt;This assume a service following
+&lt;a href=&quot;https://tools.ietf.org/html/rfc3161&quot;&gt;IETF RFC 3161&lt;/a&gt; is
+used, which specifiy the given MIME type for replies and the .tsr file
+ending for the content of such trusted timestamp.  As far as I can
+tell from the Noark 5 specifications, it is OK to have several
+variants/renderings of a dokument attached to a given
+dokumentbeskrivelse objekt.  It might be stretching it a bit to make
+some of these variants represent crypto-signatures useful for
+verifying the document integrity instead of representing the dokument
+itself.&lt;/p&gt;
+
+&lt;p&gt;Using the source of the service in formatDetaljer allow several
+timestamping services to be used.  This is useful to spread the risk
+of key compromise over several organisations.  It would only be a
+problem to trust the timestamps if all of the organisations are
+compromised.&lt;/p&gt;
+
+&lt;p&gt;The following oneliner on Linux can be used to generate the tsr
+file.  $input is the path to the file to checksum, and $sha256 is the
+SHA-256 checksum of the file (ie the &quot;&lt;sjekksum&gt;.tsr&quot; value mentioned
+above).&lt;/p&gt;

 
 &lt;p&gt;&lt;blockquote&gt;&lt;pre&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;
+openssl ts -query -data &quot;$inputfile&quot; -cert -sha256 -no_nonce \
+  | curl -s -H &quot;Content-Type: application/timestamp-query&quot; \
+      --data-binary &quot;@-&quot; http://zeitstempel.dfn.de &gt; $sha256.tsr

 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&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;To verify the timestamp, you first need to download the public key
+of the trusted timestamp service, for example using this command:&lt;/p&gt;

 
 &lt;p&gt;&lt;blockquote&gt;&lt;pre&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
-%
+wget -O ca-cert.txt \
+  https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt

 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 
 &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;Note, the public key should be stored alongside the timestamps in
+the archive to make sure it is also available 100 years from now.  It
+is probably a good idea to standardise how and were to store such
+public keys, to make it easier to find for those trying to verify
+documents 100 or 1000 years from now. :)&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;

-               <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;source src=&quot;http://simula.gunkies.org/media/625599/theora/20050421-tor-frikanalen.ogv&quot; type=&quot;video/ogg&quot;/&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;
+&lt;p&gt;The verification itself is a simple openssl command:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+openssl ts -verify -data $inputfile -in $sha256.tsr \
+  -CAfile ca-cert.txt -text
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;Is there any reason this approach would not work?  Is it somehow against
+the Noark 5 specification?&lt;/p&gt;
