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

-multi-threaded program, finally
-&lt;a href=&quot;https://tracker.debian.org/pkg/coz-profiler&quot;&gt;made it into
-Debian unstable yesterday&lt;/A&gt;.  Lluís Vilanova and I have spent many
-months since
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Coz_can_help_you_find_bottlenecks_in_multi_threaded_software___nice_free_software.html&quot;&gt;I
-blogged about the coz tool&lt;/a&gt; in August working with upstream to make
-it suitable for Debian.  There are still issues with clang
-compatibility, inline assembly only working x86 and minimized
-JavaScript libraries.&lt;/p&gt;
-
-&lt;p&gt;To test it, install &#39;coz-profiler&#39; using apt and run it like this:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;
-&lt;tt&gt;coz run --- /path/to/binary-with-debug-info&lt;/tt&gt;
-&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;This will produce a profile.coz file in the current working
-directory with the profiling information.  This is then given to a
-JavaScript application provided in the package and available from
-&lt;a href=&quot;http://plasma-umass.github.io/coz/&quot;&gt;a project web page&lt;/a&gt;.
-To start the local copy, invoke it in a browser like this:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;
-&lt;tt&gt;sensible-browser /usr/share/coz-profiler/viewer/index.htm&lt;/tt&gt;
-&lt;/blockquote&gt;&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;

-                <pubDate>Mon, 7 Nov 2016 10:25:00 +0100</pubDate>
-               <description>&lt;p&gt;A few days ago I ran a very biased and informal survey to get an
-idea about what options are being used to communicate with end to end
-encryption with friends and family.  I explicitly asked people not to
-list options only used in a work setting.  The background is the
-uneasy feeling I get when using Signal, a feeling shared by others as
-a blog post from Sander Venima about
-&lt;a href=&quot;https://sandervenema.ch/2016/11/why-i-wont-recommend-signal-anymore/&quot;&gt;why
-he do not recommend Signal anymore&lt;/a&gt; (with
-&lt;a href=&quot;https://news.ycombinator.com/item?id=12883410&quot;&gt;feedback from
-the Signal author available from ycombinator&lt;/a&gt;).  I wanted an
-overview of the options being used, and hope to include those options
-in a less biased survey later on.  So far I have not taken the time to
-look into the individual proposed systems.  They range from text
-sharing web pages, via file sharing and email to instant messaging,
-VOIP and video conferencing.  For those considering which system to
-use, it is also useful to have a look at
-&lt;a href=&quot;https://www.eff.org/secure-messaging-scorecard&quot;&gt;the EFF Secure
-messaging scorecard&lt;/a&gt; which is slightly out of date but still
-provide valuable information.&lt;/p&gt;
-
-&lt;p&gt;So, on to the list.  There were some used by many, some used by a
-few, some rarely used ones and a few mentioned but without anyone
-claiming to use them.  Notice the grouping is in reality quite random
-given the biased self selected set of participants.  First the ones
-used by many:&lt;/p&gt;
-
-&lt;ul&gt;
-
-&lt;li&gt;&lt;a href=&quot;https://whispersystems.org/&quot;&gt;Signal&lt;/a&gt;&lt;/li&gt;
-&lt;li&gt;Email w/&lt;a href=&quot;http://openpgp.org/&quot;&gt;OpenPGP&lt;/a&gt; (Enigmail, GPGSuite,etc)&lt;/li&gt;
-&lt;li&gt;&lt;a href=&quot;https://www.whatsapp.com/&quot;&gt;Whatsapp&lt;/a&gt;&lt;/li&gt;
-&lt;li&gt;IRC w/&lt;a href=&quot;https://otr.cypherpunks.ca/&quot;&gt;OTR&lt;/a&gt;&lt;/li&gt;
-&lt;li&gt;XMPP w/&lt;a href=&quot;https://otr.cypherpunks.ca/&quot;&gt;OTR&lt;/a&gt;&lt;/li&gt;
-
-&lt;/ul&gt;
-
-&lt;p&gt;Then the ones used by a few.&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;ul&gt;
+&lt;ol&gt;
 
-&lt;li&gt;&lt;a href=&quot;https://wiki.mumble.info/wiki/Main_Page&quot;&gt;Mumble&lt;/a&gt;&lt;/li&gt;
-&lt;li&gt;iMessage (included in iOS from Apple)&lt;/li&gt;
-&lt;li&gt;&lt;a href=&quot;https://telegram.org/&quot;&gt;Telegram&lt;/a&gt;&lt;/li&gt;
-&lt;li&gt;&lt;a href=&quot;https://jitsi.org/&quot;&gt;Jitsi&lt;/a&gt;&lt;/li&gt;
-&lt;li&gt;&lt;a href=&quot;https://keybase.io/download&quot;&gt;Keybase file&lt;/a&gt;&lt;/li&gt;
+&lt;li&gt;Start with a Debian machine running the Buster version (aka
+  testing).&lt;/li&gt;
 
-&lt;/ul&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;p&gt;Then the ones used by even fewer people&lt;/p&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;ul&gt;
+&lt;li&gt;Insert USB software defined radio supported by GNU Radio.&lt;/li&gt;

-
-&lt;/ul&gt;
+&lt;/ol&gt;
 
-&lt;p&gt;Given the network effect it seem obvious to me that we as a society
-have been divided and conquered by those interested in keeping
-encrypted and secure communication away from the masses.  The
-finishing remarks &lt;a href=&quot;https://vimeo.com/97505679&quot;&gt;from Aral Balkan
-in his talk &quot;Free is a lie&quot;&lt;/a&gt; about the usability of free software
-really come into effect when you want to communicate in private with
-your friends and family.  We can not expect them to allow the
-usability of communication tool to block their ability to talk to
-their loved ones.&lt;/p&gt;
-
-&lt;p&gt;Note for example the option IRC w/OTR.  Most IRC clients do not
-have OTR support, so in most cases OTR would not be an option, even if
-you wanted to.  In my personal experience, about 1 in 20 I talk to
-have a IRC client with OTR.  For private communication to really be
-available, most people to talk to must have the option in their
-currently used client.  I can not simply ask my family to install an
-IRC client.  I need to guide them through a technical multi-step
-process of adding extensions to the client to get them going.  This is
-a non-starter for most.&lt;/p&gt;
-
-&lt;p&gt;I would like to be able to do video phone calls, audio phone calls,
-exchange instant messages and share files with my loved ones, without
-being forced to share with people I do not know.  I do not want to
-share the content of the conversations, and I do not want to share who
-I communicate with or the fact that I communicate with someone.
-Without all these factors in place, my private life is being more or
-less invaded.&lt;/p&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;

-                <pubDate>Fri, 4 Nov 2016 10:15:00 +0100</pubDate>
-               <description>&lt;p&gt;A while back I received a Gyro sensor for the NXT
-&lt;a href=&quot;mindstorms.lego.com&quot;&gt;Mindstorms&lt;/a&gt; controller as a birthday
-present.  It had been on my wishlist for a while, because I wanted to
-build a Segway like balancing lego robot.  I had already built
-&lt;a href=&quot;http://www.nxtprograms.com/NXT2/segway/&quot;&gt;a simple balancing
-robot&lt;/a&gt; with the kids, using the light/color sensor included in the
-NXT kit as the balance sensor, but it was not working very well.  It
-could balance for a while, but was very sensitive to the light
-condition in the room and the reflective properties of the surface and
-would fall over after a short while.  I wanted something more robust,
-and had
-&lt;a href=&quot;https://www.hitechnic.com/cgi-bin/commerce.cgi?preadd=action&amp;key=NGY1044&quot;&gt;the
-gyro sensor from HiTechnic&lt;/a&gt; I believed would solve it on my
-wishlist for some years before it suddenly showed up as a gift from my
-loved ones. :)&lt;/p&gt;
-
-&lt;p&gt;Unfortunately I have not had time to sit down and play with it
-since then.  But that changed some days ago, when I was searching for
-lego segway information and came across a recipe from HiTechnic for
-building
-&lt;a href=&quot;http://www.hitechnic.com/blog/gyro-sensor/htway/&quot;&gt;the
-HTWay&lt;/a&gt;, a segway like balancing robot.  Build instructions and
-&lt;a href=&quot;https://www.hitechnic.com/upload/786-HTWayC.nxc&quot;&gt;source
-code&lt;/a&gt; was included, so it was just a question of putting it all
-together.  And thanks to the great work of many Debian developers, the
-compiler needed to build the source for the NXT is already included in
-Debian, so I was read to go in less than an hour.  The resulting robot
-do not look very impressive in its simplicity:&lt;/p&gt;
-
-&lt;p align=&quot;center&quot;&gt;&lt;img width=&quot;70%&quot; src=&quot;http://people.skolelinux.org/pere/blog/images/2016-11-04-lego-htway-robot.jpeg&quot;&gt;&lt;/p&gt;
-
-&lt;p&gt;Because I lack the infrared sensor used to control the robot in the
-design from HiTechnic, I had to comment out the last task
-(taskControl).  I simply placed /* and */ around it get the program
-working without that sensor present.  Now it balances just fine until
-the battery status run low:&lt;/p&gt;
-
-&lt;p align=&quot;center&quot;&gt;&lt;video width=&quot;70%&quot; controls=&quot;true&quot;&gt;
-   &lt;source src=&quot;http://people.skolelinux.org/pere/blog/images/2016-11-04-lego-htway-balancing.ogv&quot; type=&quot;video/ogg&quot;&gt;
-&lt;/video&gt;&lt;/p&gt;
-
-&lt;p&gt;Now we would like to teach it how to follow a line and take remote
-control instructions using the included Bluetooth receiver in the NXT.&lt;/p&gt;
-
-&lt;p&gt;If you, like me, love LEGO and want to make sure we find the tools
-they need to work with LEGO in Debian and all our derivative
-distributions like Ubuntu, check out
-&lt;a href=&quot;http://wiki.debian.org/LegoDesigners&quot;&gt;the LEGO designers
-project page&lt;/a&gt; and join the Debian LEGO team.  Personally I own a
-RCX and NXT controller (no EV3), and would like to make sure the
-Debian tools needed to program the systems I own work as they
-should.&lt;/p&gt;

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

-                <pubDate>Mon, 10 Oct 2016 11:30:00 +0200</pubDate>
-               <description>&lt;p&gt;In July
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/How_to_use_the_Signal_app_if_you_only_have_a_land_line__ie_no_mobile_phone_.html&quot;&gt;I
-wrote how to get the Signal Chrome/Chromium app working&lt;/a&gt; without
-the ability to receive SMS messages (aka without a cell phone).  It is
-time to share some experiences and provide an updated setup.&lt;/p&gt;
-
-&lt;p&gt;The Signal app have worked fine for several months now, and I use
-it regularly to chat with my loved ones.  I had a major snag at the
-end of my summer vacation, when the the app completely forgot my
-setup, identity and keys.  The reason behind this major mess was
-running out of disk space.  To avoid that ever happening again I have
-started storing everything in &lt;tt&gt;userdata/&lt;/tt&gt; in git, to be able to
-roll back to an earlier version if the files are wiped by mistake.  I
-had to use it once after introducing the git backup.  When rolling
-back to an earlier version, one need to use the &#39;reset session&#39; option
-in Signal to get going, and notify the people you talk with about the
-problem.  I assume there is some sequence number tracking in the
-protocol to detect rollback attacks.  The git repository is rather big
-(674 MiB so far), but I have not tried to figure out if some of the
-content can be added to a .gitignore file due to lack of spare
-time.&lt;/p&gt;
-
-&lt;p&gt;I&#39;ve also hit the 90 days timeout blocking, and noticed that this
-make it impossible to send messages using Signal.  I could still
-receive them, but had to patch the code with a new timestamp to send.
-I believe the timeout is added by the developers to force people to
-upgrade to the latest version of the app, even when there is no
-protocol changes, to reduce the version skew among the user base and
-thus try to keep the number of support requests down.&lt;/p&gt;
-
-&lt;p&gt;Since my original recipe, the Signal source code changed slightly,
-making the old patch fail to apply cleanly.  Below is an updated
-patch, including the shell wrapper I use to start Signal.  The
-original version required a new user to locate the JavaScript console
-and call a function from there.  I got help from a friend with more
-JavaScript knowledge than me to modify the code to provide a GUI
-button instead.  This mean that to get started you just need to run
-the wrapper and click the &#39;Register without mobile phone&#39; to get going
-now.  I&#39;ve also modified the timeout code to always set it to 90 days
-in the future, to avoid having to patch the code regularly.&lt;/p&gt;
-
-&lt;p&gt;So, the updated recipe for Debian Jessie:&lt;/p&gt;
+               <title>Simpler recipe on how to make a simple $7 IMSI Catcher using Debian</title>

+                <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;First, install required packages to get the source code and the
-browser you need.  Signal only work with Chrome/Chromium, as far as I
-know, so you need to install it.
+&lt;li&gt;start with a Debian machine running Stretch or newer,&lt;/li&gt;
 
-&lt;pre&gt;
-apt install git tor chromium
-git clone https://github.com/WhisperSystems/Signal-Desktop.git
-&lt;/pre&gt;&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;Modify the source code using command listed in the the patch
-block below.&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;Start Signal using the run-signal-app wrapper (for example using
-&lt;tt&gt;`pwd`/run-signal-app&lt;/tt&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;Click on the &#39;Register without mobile phone&#39;, will in a phone
-number you can receive calls to the next minute, receive the
-verification code and enter it into the form field and press
-&#39;Register&#39;.  Note, the phone number you use will be user Signal
-username, ie the way others can find you on Signal.&lt;/li&gt;
-
-&lt;li&gt;You can now use Signal to contact others.  Note, new contacts do
-not show up in the contact list until you restart Signal, and there is
-no way to assign names to Contacts.  There is also no way to create or
-update chat groups.  I suspect this is because the web app do not have
-a associated contact database.&lt;/li&gt;
+&lt;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;I am still a bit uneasy about using Signal, because of the way its
-main author moxie0 reject federation and accept dependencies to major
-corporations like Google (part of the code is fetched from Google) and
-Amazon (the central coordination point is owned by Amazon).  See for
-example
-&lt;a href=&quot;https://github.com/LibreSignal/LibreSignal/issues/37&quot;&gt;the
-LibreSignal issue tracker&lt;/a&gt; for a thread documenting the authors
-view on these issues.  But the network effect is strong in this case,
-and several of the people I want to communicate with already use
-Signal.  Perhaps we can all move to &lt;a href=&quot;https://ring.cx/&quot;&gt;Ring&lt;/a&gt;
-once it &lt;a href=&quot;https://bugs.debian.org/830265&quot;&gt;work on my
-laptop&lt;/a&gt;?  It already work on Windows and Android, and is included
-in &lt;a href=&quot;https://tracker.debian.org/pkg/ring&quot;&gt;Debian&lt;/a&gt; and
-&lt;a href=&quot;https://launchpad.net/ubuntu/+source/ring&quot;&gt;Ubuntu&lt;/a&gt;, but not
-working on Debian Stable.&lt;/p&gt;
-
-&lt;p&gt;Anyway, this is the patch I apply to the Signal code to get it
-working.  It switch to the production servers, disable to timeout,
-make registration easier and add the shell wrapper:&lt;/p&gt;
-
-&lt;pre&gt;

+&lt;p&gt;To make it even easier in the future to get this sniffer up and

+&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;

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

+                <pubDate>Tue, 27 Jun 2017 17:50:00 +0200</pubDate>
+               <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

+&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;&lt;a href=&quot;http://packages.qa.debian.org/isenkram&quot;&gt;The Isenkram
-system&lt;/a&gt; provide a practical and easy way to figure out which
-packages support the hardware in a given machine.  The command line
-tool &lt;tt&gt;isenkram-lookup&lt;/tt&gt; and the tasksel options provide a
-convenient way to list and install packages relevant for the current
-hardware during system installation, both user space packages and
-firmware packages. The GUI background daemon on the other hand provide
-a pop-up proposing to install packages when a new dongle is inserted
-while using the computer.  For example, if you plug in a smart card
-reader, the system will ask if you want to install &lt;tt&gt;pcscd&lt;/tt&gt; if
-that package isn&#39;t already installed, and if you plug in a USB video
-camera the system will ask if you want to install &lt;tt&gt;cheese&lt;/tt&gt; if
-cheese is currently missing.  This already work just fine.&lt;/p&gt;
-
-&lt;p&gt;But Isenkram depend on a database mapping from hardware IDs to
-package names.  When I started no such database existed in Debian, so
-I made my own data set and included it with the isenkram package and
-made isenkram fetch the latest version of this database from git using
-http.  This way the isenkram users would get updated package proposals
-as soon as I learned more about hardware related packages.&lt;/p&gt;
-
-&lt;p&gt;The hardware is identified using modalias strings.  The modalias
-design is from the Linux kernel where most hardware descriptors are
-made available as a strings that can be matched using filename style
-globbing.  It handle USB, PCI, DMI and a lot of other hardware related
-identifiers.&lt;/p&gt;
-
-&lt;p&gt;The downside to the Isenkram specific database is that there is no
-information about relevant distribution / Debian version, making
-isenkram propose obsolete packages too.  But along came AppStream, a
-cross distribution mechanism to store and collect metadata about
-software packages.  When I heard about the proposal, I contacted the
-people involved and suggested to add a hardware matching rule using
-modalias strings in the specification, to be able to use AppStream for
-mapping hardware to packages.  This idea was accepted and AppStream is
-now a great way for a package to announce the hardware it support in a
-distribution neutral way.  I wrote
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Using_appstream_with_isenkram_to_install_hardware_related_packages_in_Debian.html&quot;&gt;a
-recipe on how to add such meta-information&lt;/a&gt; in a blog post last
-December.  If you have a hardware related package in Debian, please
-announce the relevant hardware IDs using AppStream.&lt;/p&gt;
-
-&lt;p&gt;In Debian, almost all packages that can talk to a LEGO Mindestorms
-RCX or NXT unit, announce this support using AppStream.  The effect is
-that when you insert such LEGO robot controller into your Debian
-machine, Isenkram will propose to install the packages needed to get
-it working.  The intention is that this should allow the local user to
-start programming his robot controller right away without having to
-guess what packages to use or which permissions to fix.&lt;/p&gt;
-
-&lt;p&gt;But when I sat down with my son the other day to program our NXT
-unit using his Debian Stretch computer, I discovered something
-annoying.  The local console user (ie my son) did not get access to
-the USB device for programming the unit.  This used to work, but no
-longer in Jessie and Stretch.  After some investigation and asking
-around on #debian-devel, I discovered that this was because udev had
-changed the mechanism used to grant access to local devices.  The
-ConsoleKit mechanism from &lt;tt&gt;/lib/udev/rules.d/70-udev-acl.rules&lt;/tt&gt;
-no longer applied, because LDAP users no longer was added to the
-plugdev group during login.  Michael Biebl told me that this method
-was obsolete and the new method used ACLs instead.  This was good
-news, as the plugdev mechanism is a mess when using a remote user
-directory like LDAP.  Using ACLs would make sure a user lost device
-access when she logged out, even if the user left behind a background
-process which would retain the plugdev membership with the ConsoleKit
-setup.  Armed with this knowledge I moved on to fix the access problem
-for the LEGO Mindstorms related packages.&lt;/p&gt;
-
-&lt;p&gt;The new system uses a udev tag, &#39;uaccess&#39;.  It can either be
-applied directly for a device, or is applied in
-/lib/udev/rules.d/70-uaccess.rules for classes of devices.  As the
-LEGO Mindstorms udev rules did not have a class, I decided to add the
-tag directly in the udev rules files included in the packages.  Here
-is one example.  For the nqc C compiler for the RCX, the
-&lt;tt&gt;/lib/udev/rules.d/60-nqc.rules&lt;/tt&gt; file now look like this:
-
-&lt;p&gt;&lt;pre&gt;
-SUBSYSTEM==&quot;usb&quot;, ACTION==&quot;add&quot;, ATTR{idVendor}==&quot;0694&quot;, ATTR{idProduct}==&quot;0001&quot;, \
-    SYMLINK+=&quot;rcx-%k&quot;, TAG+=&quot;uaccess&quot;
-&lt;/pre&gt;&lt;/p&gt;
-
-&lt;p&gt;The key part is the &#39;TAG+=&quot;uaccess&quot;&#39; at the end.  I suspect all
-packages using plugdev in their /lib/udev/rules.d/ files should be
-changed to use this tag (either directly or indirectly via
-&lt;tt&gt;70-uaccess.rules&lt;/tt&gt;).  Perhaps a lintian check should be created
-to detect this?&lt;/p&gt;
-
-&lt;p&gt;I&#39;ve been unable to find good documentation on the uaccess feature.
-It is unclear to me if the uaccess tag is an internal implementation
-detail like the udev-acl tag used by
-&lt;tt&gt;/lib/udev/rules.d/70-udev-acl.rules&lt;/tt&gt;.  If it is, I guess the
-indirect method is the preferred way.  Michael
-&lt;a href=&quot;https://github.com/systemd/systemd/issues/4288&quot;&gt;asked for more
-documentation from the systemd project&lt;/a&gt; and I hope it will make
-this clearer.  For now I use the generic classes when they exist and
-is already handled by &lt;tt&gt;70-uaccess.rules&lt;/tt&gt;, and add the tag
-directly if no such class exist.&lt;/p&gt;

+               <description>&lt;p&gt;It is pleasing to see that the work we put down in publishing new
+editions 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, is still being appreciated.  I had a look at the
+latest sales numbers for the paper edition today.  Not too impressive,
+but happy to see some buyers still exist.  All the revenue from the
+books is sent to the &lt;a href=&quot;https://creativecommons.org/&quot;&gt;Creative
+Commons Corporation&lt;/a&gt;, and they receive the largest cut if you buy
+directly from Lulu.  Most books are sold via Amazon, with Ingram
+second and only a small fraction directly from Lulu.  The ebook
+edition is available for free from

-                <pubDate>Fri, 9 Sep 2016 11:30:00 +0200</pubDate>
-               <description>&lt;p&gt;En av dagens nyheter er at Aftenpostens redaktør Espen Egil Hansen
-bruker
-&lt;a href=&quot;https://www.nrk.no/kultur/aftenposten-brukar-heile-forsida-pa-facebook-kritikk-1.13126918&quot;&gt;forsiden
-av papiravisen på et åpent brev til Facebooks sjef Mark Zuckerberg om
-Facebooks fjerning av bilder, tekster og sider de ikke liker&lt;/a&gt;.  Det
-må være uvant for redaktøren i avisen Aftenposten å stå med lua i
-handa og håpe på å bli hørt.  Spesielt siden Aftenposten har vært med
-på å gi Facebook makten de nå demonstrerer at de har.  Ved å melde seg
-inn i Facebook-samfunnet har de sagt ja til bruksvilkårene og inngått
-en antagelig bindende avtale.  Kanskje de skulle lest og vurdert
-vilkårene litt nærmere før de sa ja, i stedet for å klage over at
-reglende de har valgt å akseptere blir fulgt?  Personlig synes jeg
-vilkårene er uakseptable og det ville ikke falle meg inn å gå inn på
-en avtale med slike vilkår.  I tillegg til uakseptable vilkår er det
-mange andre grunner til å unngå Facebook.  Du kan finne en solid
-gjennomgang av flere slike argumenter hos
-&lt;a href=&quot;https://stallman.org/facebook.html&quot;&gt;Richard Stallmans side om
-Facebook&lt;/a&gt;.
-
-&lt;p&gt;Jeg håper flere norske redaktører på samme vis må stå med lua i
-hånden inntil de forstår at de selv er med på å føre samfunnet på
-ville veier ved å omfavne Facebook slik de gjør når de omtaler og
-løfter frem saker fra Facebook, og tar i bruk Facebook som
-distribusjonskanal for sine nyheter.  De bidrar til
-overvåkningssamfunnet og raderer ut lesernes privatsfære når de lenker
-til Facebook på sine sider, og låser seg selv inne i en omgivelse der
-det er Facebook, og ikke redaktøren, som sitter med makta.&lt;/p&gt;
-
-&lt;p&gt;Men det vil nok ta tid, i et Norge der de fleste nettredaktører
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Snurpenot_overv_kning_av_sensitiv_personinformasjon.html&quot;&gt;deler
-sine leseres personopplysinger med utenlands etterretning&lt;/a&gt;.&lt;/p&gt;
-
-&lt;p&gt;For øvrig burde varsleren Edward Snowden få politisk asyl i
-Norge.&lt;/p&gt;

+               <description>&lt;p&gt;I am very happy to report that the
+&lt;a href=&quot;https://github.com/hiOA-ABI/nikita-noark5-core&quot;&gt;Nikita Noark 5
+core project&lt;/a&gt; tagged its second release today.  The free software
+solution is an implementation of the Norwegian archive standard Noark
+5 used by government offices in Norway.  These were the changes in
+version 0.1.1 since version 0.1.0 (from NEWS.md):
+
+&lt;ul&gt;
+
+ &lt;li&gt;Continued work on the angularjs GUI, including document upload.&lt;/li&gt;
+ &lt;li&gt;Implemented correspondencepartPerson, correspondencepartUnit and
+   correspondencepartInternal&lt;/li&gt;
+ &lt;li&gt;Applied for coverity coverage and started submitting code on
+   regualr basis.&lt;/li&gt;
+ &lt;li&gt;Started fixing bugs reported by coverity&lt;/li&gt;
+ &lt;li&gt;Corrected and completed HATEOAS links to make sure entire API is
+   available via URLs in _links.&lt;/li&gt;
+ &lt;li&gt;Corrected all relation URLs to use trailing slash.&lt;/li&gt;
+ &lt;li&gt;Add initial support for storing data in ElasticSearch.&lt;/li&gt;
+ &lt;li&gt;Now able to receive and store uploaded files in the archive.&lt;/li&gt;
+ &lt;li&gt;Changed JSON output for object lists to have relations in _links.&lt;/li&gt;
+ &lt;li&gt;Improve JSON output for empty object lists.&lt;/li&gt;
+ &lt;li&gt;Now uses correct MIME type application/vnd.noark5-v4+json.&lt;/li&gt;
+ &lt;li&gt;Added support for docker container images.&lt;/li&gt;
+ &lt;li&gt;Added simple API browser implemented in JavaScript/Angular.&lt;/li&gt;
+ &lt;li&gt;Started on archive client implemented in JavaScript/Angular.&lt;/li&gt;
+ &lt;li&gt;Started on prototype to show the public mail journal.&lt;/li&gt;
+ &lt;li&gt;Improved performance by disabling Sprint FileWatcher.&lt;/li&gt;
+ &lt;li&gt;Added support for &#39;arkivskaper&#39;, &#39;saksmappe&#39; and &#39;journalpost&#39;.&lt;/li&gt;
+ &lt;li&gt;Added support for some metadata codelists.&lt;/li&gt;
+ &lt;li&gt;Added support for Cross-origin resource sharing (CORS).&lt;/li&gt;
+ &lt;li&gt;Changed login method from Basic Auth to JSON Web Token (RFC 7519)
+   style.&lt;/li&gt;
+ &lt;li&gt;Added support for GET-ing ny-* URLs.&lt;/li&gt;
+ &lt;li&gt;Added support for modifying entities using PUT and eTag.&lt;/li&gt;
+ &lt;li&gt;Added support for returning XML output on request.&lt;/li&gt;
+ &lt;li&gt;Removed support for English field and class names, limiting ourself
+   to the official names.&lt;/li&gt;

-                <pubDate>Tue, 6 Sep 2016 23:00:00 +0200</pubDate>
-               <description>&lt;p&gt;I helga kom det et hårreisende forslag fra Lysne II-utvalget satt
-ned av Forsvarsdepartementet.  Lysne II-utvalget var bedt om å vurdere
-ønskelista til Forsvarets etterretningstjeneste (e-tjenesten), og har
-kommet med
-&lt;a href=&quot;http://www.aftenposten.no/norge/Utvalg-sier-ja-til-at-E-tjenesten-far-overvake-innholdet-i-all-internett--og-telefontrafikk-som-krysser-riksgrensen-603232b.html&quot;&gt;forslag
-om at e-tjenesten skal få lov til a avlytte all Internett-trafikk&lt;/a&gt;
-som passerer Norges grenser.  Få er klar over at dette innebærer at
-e-tjenesten får tilgang til epost sendt til de fleste politiske
-partiene på Stortinget.  Regjeringspartiet Høyre (@hoyre.no),
-støttepartiene Venstre (@venstre.no) og Kristelig Folkeparti (@krf.no)
-samt Sosialistisk Ventreparti (@sv.no) og Miljøpartiet de grønne
-(@mdg.no) har nemlig alle valgt å ta imot eposten sin via utenlandske
-tjenester.  Det betyr at hvis noen sender epost til noen med en slik
-adresse vil innholdet i eposten, om dette forslaget blir vedtatt, gjøres
-tilgjengelig for e-tjenesten.  Venstre, Sosialistisk Ventreparti og
-Miljøpartiet De Grønne har valgt å motta sin epost hos Google,
-Kristelig Folkeparti har valgt å motta sin epost hos Microsoft, og
-Høyre har valgt å motta sin epost hos Comendo med mottak i Danmark og
-Irland.  Kun Arbeiderpartiet og Fremskrittspartiet har valgt å motta
-eposten sin i Norge, hos henholdsvis Intility AS og Telecomputing
-AS.&lt;/p&gt;
-
-&lt;p&gt;Konsekvensen er at epost inn og ut av de politiske organisasjonene,
-til og fra partimedlemmer og partiets tillitsvalgte vil gjøres
-tilgjengelig for e-tjenesten for analyse og sortering.  Jeg mistenker
-at kunnskapen som slik blir tilgjengelig vil være nyttig hvis en
-ønsker å vite hvilke argumenter som treffer publikum når en ønsker å
-påvirke Stortingets representanter.&lt;/p
-
-&lt;p&gt;Ved hjelp av MX-oppslag i DNS for epost-domene, tilhørende
-whois-oppslag av IP-adressene og traceroute for å se hvorvidt
-trafikken går via utlandet kan enhver få bekreftet at epost sendt til
-de omtalte partiene vil gjøres tilgjengelig for forsvarets
-etterretningstjeneste hvis forslaget blir vedtatt.  En kan også bruke
-den kjekke nett-tjenesten &lt;a href=&quot;http://ipinfo.io/&quot;&gt;ipinfo.io&lt;/a&gt;
-for å få en ide om hvor i verden en IP-adresse hører til.&lt;/p&gt;
-
-&lt;p&gt;På den positive siden vil forslaget gjøre at enda flere blir
-motivert til å ta grep for å bruke
-&lt;a href=&quot;https://www.torproject.org/&quot;&gt;Tor&lt;/a&gt; og krypterte
-kommunikasjonsløsninger for å kommunisere med sine kjære, for å sikre
-at privatsfæren vernes.  Selv bruker jeg blant annet
-&lt;a href=&quot;https://www.freedomboxfoundation.org/&quot;&gt;FreedomBox&lt;/a&gt; og
-&lt;a href=&quot;https://whispersystems.org/&quot;&gt;Signal&lt;/a&gt; til slikt.  Ingen av
-dem er optimale, men de fungerer ganske bra allerede og øker kostnaden
-for dem som ønsker å invadere mitt privatliv.&lt;/p&gt;
-
-&lt;p&gt;For øvrig burde varsleren Edward Snowden få politisk asyl i
-Norge.&lt;/p&gt;

+                <pubDate>Wed, 7 Jun 2017 21:40:00 +0200</pubDate>
+               <description>&lt;p&gt;&lt;em&gt;This is a copy of
+&lt;a href=&quot;https://lists.nuug.no/pipermail/nikita-noark/2017-June/000297.html&quot;&gt;an
+email I posted to the nikita-noark mailing list&lt;/a&gt;.  Please follow up
+there if you would like to discuss this topic.  The background is that
+we are making a free software archive system based on the Norwegian
+&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 $sha256 is the
+SHA-256 checksum of the file (ie the &quot;&lt;sjekksum&gt;.tsr&quot; value mentioned
+above).&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+openssl ts -query -data &quot;$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;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;
+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;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;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;
