-<a href="http://people.skolelinux.org/pere/blog/Lets_make_a_Norwegian_Bokm_l_edition_of_The_Debian_Administrator_s_Handbook">started
-to work</a> on a Norwegian Bokmål edition of the "open access" 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 <a href="https://debian-handbook.info/get/">get the Debian
-Administrator's Handbook page</a> (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
-<a href="https://hosted.weblate.org/projects/debian-handbook/">the
-hosted weblate project page</a>, and get in touch using
-<a href="http://lists.alioth.debian.org/mailman/listinfo/debian-handbook-translators">the
-translators mailing list</a>. Please also check out
-<a href="https://debian-handbook.info/contribute/">the instructions for
-contributors</a>. A good way to contribute is to proofread the text
-and update weblate if you find errors.</p>

-<p>Our goal is still to make the Norwegian book available in paper as well as
-electronic form.</p>

+ <div class="date">25th October 2017</div>
+ <div class="body"><p>Recently, I needed to automatically check the copyright status of a
+set of <a href="http://www.imdb.com/">The Internet Movie database
+(IMDB)</a> entries, to figure out which one of the movies they refer
+to can be freely distributed on the Internet. This proved to be
+harder than it sounds. IMDB for sure list movies without any
+copyright protection, where the copyright protection has expired or
+where the movie is lisenced using a permissive license like one from
+Creative Commons. These are mixed with copyright protected movies,
+and there seem to be no way to separate these classes of movies using
+the information in IMDB.</p>
+
+<p>First I tried to look up entries manually in IMDB,
+<a href="https://www.wikipedia.org/">Wikipedia</a> and
+<a href="https://www.archive.org/">The Internet Archive</a>, to get a
+feel how to do this. It is hard to know for sure using these sources,
+but it should be possible to be reasonable confident a movie is "out
+of copyright" with a few hours work per movie. As I needed to check
+almost 20,000 entries, this approach was not sustainable. I simply
+can not work around the clock for about 6 years to check this data
+set.</p>
+
+<p>I asked the people behind The Internet Archive if they could
+introduce a new metadata field in their metadata XML for IMDB ID, but
+was told that they leave it completely to the uploaders to update the
+metadata. Some of the metadata entries had IMDB links in the
+description, but I found no way to download all metadata files in bulk
+to locate those ones and put that approach aside.</p>
+
+<p>In the process I noticed several Wikipedia articles about movies
+had links to both IMDB and The Internet Archive, and it occured to me
+that I could use the Wikipedia RDF data set to locate entries with
+both, to at least get a lower bound on the number of movies on The
+Internet Archive with a IMDB ID. This is useful based on the
+assumption that movies distributed by The Internet Archive can be
+legally distributed on the Internet. With some help from the RDF
+community (thank you DanC), I was able to come up with this query to
+pass to <a href="https://query.wikidata.org/">the SPARQL interface on
+Wikidata</a>:
+
+<p><pre>
+SELECT ?work ?imdb ?ia ?when ?label
+WHERE
+{
+ ?work wdt:P31/wdt:P279* wd:Q11424.
+ ?work wdt:P345 ?imdb.
+ ?work wdt:P724 ?ia.
+ OPTIONAL {
+ ?work wdt:P577 ?when.
+ ?work rdfs:label ?label.
+ FILTER(LANG(?label) = "en").
+ }
+}
+</pre></p>
+
+<p>If I understand the query right, for every film entry anywhere in
+Wikpedia, it will return the IMDB ID and The Internet Archive ID, and
+when the movie was released and its English title, if either or both
+of the latter two are available. At the moment the result set contain
+2338 entries. Of course, it depend on volunteers including both
+correct IMDB and The Internet Archive IDs in the wikipedia articles
+for the movie. It should be noted that the result will include
+duplicates if the movie have entries in several languages. There are
+some bogus entries, either because The Internet Archive ID contain a
+typo or because the movie is not available from The Internet Archive.
+I did not verify the IMDB IDs, as I am unsure how to do that
+automatically.</p>
+
+<p>I wrote a small python script to extract the data set from Wikidata
+and check if the XML metadata for the movie is available from The
+Internet Archive, and after around 1.5 hour it produced a list of 2097
+free movies and their IMDB ID. In total, 171 entries in Wikidata lack
+the refered Internet Archive entry. I assume the 60 "disappearing"
+entries (ie 2338-2097-171) are duplicate entries.</p>
+
+<p>This is not too bad, given that The Internet Archive report to
+contain <a href="https://archive.org/details/feature_films">5331
+feature films</a> at the moment, but it also mean more than 3000
+movies are missing on Wikipedia or are missing the pair of references
+on Wikipedia.</p>
+
+<p>I was curious about the distribution by release year, and made a
+little graph to show how the amount of free movies is spread over the
+years:<p>
+
+<p><img src="http://people.skolelinux.org/pere/blog/images/2017-10-25-verk-i-det-fri-filmer.png"></p>
+
+<p>I expect the relative distribution of the remaining 3000 movies to
+be similar.</p>
+
+<p>If you want to help, and want to ensure Wikipedia can be used to
+cross reference The Internet Archive and The Internet Movie Database,
+please make sure entries like this are listed under the "External
+links" heading on the Wikipedia article for the movie:</p>
+
+<p><pre>
+* {{Internet Archive film|id=FightingLady}}
+* {{IMDb title|id=0036823|title=The Fighting Lady}}
+</pre></p>
+
+<p>Please verify the links on the final page, to make sure you did not
+introduce a typo.</p>
+
+<p>Here is the complete list, if you want to correct the 171
+identified Wikipedia entries with broken links to The Internet

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

- <div class="date"> 5th August 2016</div>
- <div class="body"><p>As my regular readers probably remember, the last year I published
-a French and Norwegian translation of the classic
-<a href="http://www.free-culture.cc/">Free Culture book</a> 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.</p>
-
-<p>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:</p>
-
-<table border="0">
-<tr><th>Title / language</th><th>Quantity</th></tr>
-<tr><td><a href="http://www.lulu.com/shop/lawrence-lessig/culture-libre/paperback/product-22645082.html">Culture Libre / French</a></td><td align="right">3</td></tr>
-<tr><td><a href="http://www.lulu.com/shop/lawrence-lessig/fri-kultur/paperback/product-22441576.html">Fri kultur / Norwegian</a></td><td align="right">7</td></tr>

-</table>
-
-<p>The books are available both from Lulu.com and from large book
-stores like Amazon and Barnes&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.</p>
-
-<p>The ebook edition is available for free from
-<a href="https://github.com/petterreinholdtsen/free-culture-lessig">Github</a>.</p>
-
-<p>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.</p>

+ <div class="date"> 9th October 2017</div>
+ <div class="body"><p>At my nearby maker space,
+<a href="http://sonen.ifi.uio.no/">Sonen</a>, I heard the story that it
+was easier to generate gcode files for theyr 3D printers (Ultimake 2+)
+on Windows and MacOS X than Linux, because the software involved had
+to be manually compiled and set up on Linux while premade packages
+worked out of the box on Windows and MacOS X. I found this annoying,
+as the software involved,
+<a href="https://github.com/Ultimaker/Cura">Cura</a>, is free software
+and should be trivial to get up and running on Linux if someone took
+the time to package it for the relevant distributions. I even found
+<a href="https://bugs.debian.org/706656">a request for adding into
+Debian</a> from 2013, which had seem some activity over the years but
+never resulted in the software showing up in Debian. So a few days
+ago I offered my help to try to improve the situation.</p>
+
+<p>Now I am very happy to see that all the packages required by a
+working Cura in Debian are uploaded into Debian and waiting in the NEW
+queue for the ftpmasters to have a look. You can track the progress
+on
+<a href="https://qa.debian.org/developer.php?email=3dprinter-general%40lists.alioth.debian.org">the
+status page for the 3D printer team</a>.</p>
+
+<p>The uploaded packages are a bit behind upstream, and was uploaded
+now to get slots in <a href="https://ftp-master.debian.org/new.html">the NEW
+queue</a> while we work up updating the packages to the latest
+upstream version.</p>
+
+<p>On a related note, two competitors for Cura, which I found harder
+to use and was unable to configure correctly for Ultimaker 2+ in the
+short time I spent on it, are already in Debian. If you are looking
+for 3D printer "slicers" and want something already available in
+Debian, check out
+<a href="https://tracker.debian.org/pkg/slic3r">slic3r</a> and
+<a href="https://tracker.debian.org/pkg/slic3r-prusa">slic3r-prusa</a>.
+The latter is a fork of the former.</p>

-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
-fra Barry Karr hos The Skeptical Inquirer som hadde sjekket og fått OK
-fra Robyn Asimov som representerte arvingene i Asmiov-familien og gikk
-igang med oversettingen.</p>
-
-<p>Resultatet, <a href="http://www.skepsis.no/?p=1617">«Relativt
-feil»</a>, ble publisert på skepsis-bloggen for noen minutter siden.
-Jeg anbefaler deg på det varmeste å lese denne teksten og dele den med
-dine venner.</p>
-
-<p>For å håndtere oversettelsen og sikre at original og oversettelse
-var i sync brukte vi git, po4a, GNU make og Transifex. Det hele
-fungerte utmerket og gjorde det enkelt å dele tekstene og jobbe sammen
-om finpuss på formuleringene. Hadde hosted.weblate.org latt meg
-opprette nye prosjekter selv i stedet for å måtte kontakte

+Sone from the Computer Science department of the University of
+Oslo</a>. The presentation will show the nearby mobile phones (aka

+representing mobile base station it is talking to. It was working in
+the lab yesterday, and was moved into place this morning.</p>
+
+<p>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
+<a href="https://github.com/marlow925/hopglass">English version of

+<a href="https://tracker.debian.org/pkg/gr-gsm">gr-gsm</a> converting
+the radio signal to data packages is quite CPU intensive.</p>
+
+<p>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
+<a href="https://github.com/petterreinholdtsen/IMSI-catcher/tree/meshviewer-output">patches
+in my meshviewer-output branch</a>. 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

- <div class="date"> 7th July 2016</div>
- <div class="body"><p>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
-<a href="https://blog.torproject.org/blog/mission-impossible-hardening-android-security-and-privacy">an
-hardened Android installation</a> 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
-<a href="http://wiki.cyanogenmod.org/w/Install_CM_for_ace">install
-CyanogenMod on it</a>, but did not quite find time to start on it
-until a few days ago.</p>
-
-<p>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
-'fastboot' before (3) connecting the device via USB to a Linux
-machine, (4) request the device identifier token by running 'fastboot
-oem get_identifier_token', (5) request the device unlocking key using
-the <a href="http://www.htcdev.com/bootloader/">HTC developer web
-site</a> and unlock the phone using the key file emailed to you.</p>
-
-<p>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.</p>
-
-<p>First I needed to extract the hboot firmware from
-<a href="http://www.htcdev.com/ruu/PD9810000_Ace_Sense30_S_hboot_2.00.0029.exe">the
-windows binary for HTC Desire HD</a> downloaded as 'the RUU' from HTC.
-For this there is is <a href="https://github.com/kmdm/unruu/">a github
-project named unruu</a> 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.</p>
-
-<p>Next, I needed to get the new firmware into the device. For this I
-followed some instructions
-<a href="http://www.htc1guru.com/2013/09/new-ruu-zips-posted/">available
-from HTC1Guru.com</a>, and ran these commands as root on a Linux
-machine with Debian testing:</p>
-
-<p><pre>
-adb reboot-bootloader
-fastboot oem rebootRUU
-fastboot flash zip rom.zip
-fastboot flash zip rom.zip
-fastboot reboot
-</pre></p>
-
-<p>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.</p>
-
-<p>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:</p>
-
-<p><pre>
-fastboot oem get_identifier_token 2>&1 | sed 's/(bootloader) //'
-</pre>
-
-<p>And once I got the unlock code via email, I could use it like
-this:</p>
-
-<p><pre>
-fastboot flash unlocktoken Unlock_code.bin
-</pre></p>
-
-<p>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 <a href="https://www.debian.org/">Debian</a> on it. :)</p>

+ <div class="body"><p>A little more than a month ago I wrote
+<a href="http://people.skolelinux.org/pere/blog/Simpler_recipe_on_how_to_make_a_simple__7_IMSI_Catcher_using_Debian.html">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</a>, 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.</p>
+
+<p>The <a href="https://tracker.debian.org/pkg/gr-gsm">gr-gsm</a>
+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.</p>
+
+<p>Here is an updated recipe, using packages built by Debian and a git
+clone of two python scripts:</p>
+
+<ol>
+
+<li>Start with a Debian machine running the Buster version (aka
+ testing).</li>
+
+<li>Run '<tt>apt install gr-gsm python-numpy python-scipy
+ python-scapy</tt>' as root to install required packages.</li>
+
+<li>Fetch the code decoding GSM packages using '<tt>git clone
+ github.com/Oros42/IMSI-catcher.git</tt>'.</li>
+
+<li>Insert USB software defined radio supported by GNU Radio.</li>
+
+<li>Enter the IMSI-catcher directory and run '<tt>python
+ scan-and-livemon</tt>' to locate the frequency of nearby base
+ stations and start listening for GSM packages on one of them.</li>
+
+<li>Enter the IMSI-catcher directory and run '<tt>python
+ simple_IMSI-catcher.py</tt>' to display the collected information.</li>
+
+</ol>
+
+<p>Note, due to a bug somewhere the scan-and-livemon program (actually
+<a href="https://github.com/ptrkrysik/gr-gsm/issues/336">its underlying
+program grgsm_scanner</a>) do not work with the HackRF radio. It does
+work with RTL 8232 and other similar USB radio receivers you can get
+very cheaply
+(<a href="https://www.ebay.com/sch/items/?_nkw=rtl+2832">for example
+from ebay</a>), so for now the solution is to scan using the RTL radio
+and only use HackRF for fetching GSM data.</p>
+
+<p>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.</p>
+
+<p>I've tried to run the scanner on a
+<a href="https://wiki.debian.org/RaspberryPi">Raspberry Pi 2 and 3
+running Debian Buster</a>, but the grgsm_livemon_headless process seem
+to be too CPU intensive to keep up. When GNU Radio print 'O' 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 'O'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().</p>

- <div class="date"> 3rd July 2016</div>
- <div class="body"><p>For a while now, I have wanted to test
-<a href="https://whispersystems.org/">the Signal app</a>, 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
-<a href="https://chrome.google.com/webstore/detail/signal-private-messenger/bikioccmkafdpakkkcpdbppfkghcmihk?hl=en-US">the
-Signal Chrome app</a> available from the Chrome web store, applied
-patches to use the production Signal servers, started the app and
-asked for the hidden "register without a smart phone" form. Here is
-the recipe how I did it.</p>
-
-<p>First, I fetched the Signal desktop source from Github, using
-
-<pre>
-git clone https://github.com/WhisperSystems/Signal-Desktop.git
-</pre>
-
-<p>Next, I patched the source to use the production servers, to be
-able to talk to other Signal users:</p>

-<p>The first part is changing the servers, and the second is updating

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

+
+<p>Det er tydelig fra diskusjonen rundt grenseløs digital overvåkning

- <div class="date"> 6th June 2016</div>
- <div class="body"><p>When I set out a few weeks ago to figure out
-<a href="http://people.skolelinux.org/pere/blog/What_is_the_best_multimedia_player_in_Debian_.html">which
-multimedia player in Debian claimed to support most file formats /
-MIME types</a>, 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.</p>
-
-<p>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
-<a href="https://wiki.debian.org/DebianMultimedia/PlayerSupport">Multimedia
-player MIME type support status</a> Debian wiki page.</p>
-
-<p>The new "best" 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.</p>
-
-<p>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.</p>

+ <div class="date"> 9th August 2017</div>
+ <div class="body"><p>On friday, I came across an interesting article in the Norwegian
+web based ICT news magazine digi.no on
+<a href="https://www.digi.no/artikler/sikkerhetsforsker-lagde-enkel-imsi-catcher-for-60-kroner-na-kan-mobiler-kartlegges-av-alle/398588">how
+to collect the IMSI numbers of nearby cell phones</a> using the cheap
+DVB-T software defined radios. The article refered to instructions
+and <a href="https://www.youtube.com/watch?v=UjwgNd_as30">a recipe by
+Keld Norman on Youtube on how to make a simple $7 IMSI Catcher</a>, and I decided to test them out.</p>
+
+<p>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->pip->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.</p>
+
+<p>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've been testing the
+collector for a few days now.</p>
+
+<p>The updated and simpler recipe is thus to</p>
+
+<ol>
+
+<li>start with a Debian machine running Stretch or newer,</li>
+
+<li>build and install the gr-gsm package available from
+<a href="http://ppa.launchpad.net/ptrkrysik/gr-gsm/ubuntu/pool/main/g/gr-gsm/">http://ppa.launchpad.net/ptrkrysik/gr-gsm/ubuntu/pool/main/g/gr-gsm/</a>,</li>
+
+<li>clone the git repostory from <a href="https://github.com/Oros42/IMSI-catcher">https://github.com/Oros42/IMSI-catcher</a>,</li>
+
+<li>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).</li>
+
+<li>go into the IMSI-catcher directory and run 'sudo python simple_IMSI-catcher.py' to extract the IMSI numbers.</li>
+
+</ol>
+
+<p>To make it even easier in the future to get this sniffer up and
+running, I decided to package
+<a href="https://github.com/ptrkrysik/gr-gsm/">the gr-gsm project</a>
+for Debian (<a href="https://bugs.debian.org/871055">WNPP
+#871055</a>), 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.</p>
+
+<p>I doubt this "IMSI cacher" is anywhere near as powerfull as
+commercial tools like
+<a href="https://www.thespyphone.com/portable-imsi-imei-catcher/">The
+Spy Phone Portable IMSI / IMEI Catcher</a> or the
+<a href="https://en.wikipedia.org/wiki/Stingray_phone_tracker">Harris
+Stingray</a>, 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...</p>
+
+<p>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?</p>

- <div class="date"> 5th June 2016</div>
- <div class="body"><p>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 –
-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'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't.</p>
-
-<p>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 <tt>file --mime-type</tt>
-returning the application/ogg MIME type, which no video player I had
-installed listed as a MIME type they would understand. I asked for
-<a href="http://bugs.gw.com/view.php?id=382">file to change its
-behavour</a> 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.</p>
-
-<p>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've reported <a href="http://bugs.debian.org/825993">the
-rosegarden problem to BTS</a> 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.</p>
-
-<p>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
-<tt>file --mime-type</tt> 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
-<a href="https://www.freedesktop.org/wiki/Specifications/desktop-entry-spec/">the
-desktop files</a> 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 'Open with' or similar. In general
-this work well. But it depend on each program picking a good MIME
-type (preferably
-<a href="http://www.iana.org/assignments/media-types/media-types.xhtml">a
-MIME type registered with IANA</a>), 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.</p>
-
-<p>The <tt>/usr/share/mime/packages/rosegarden.xml</tt> entry for
-<a href="http://www.freedesktop.org/wiki/Specifications/shared-mime-info-spec">the
-Shared MIME database</a> look like this:</p>
-
-<p><blockquote><pre>
-<?xml version="1.0" encoding="UTF-8"?>
-<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
- <mime-type type="audio/x-rosegarden">
- <sub-class-of type="application/x-gzip"/>
- <comment>Rosegarden project file</comment>
- <glob pattern="*.rg"/>
- </mime-type>
-</mime-info>
-</pre></blockquote></p>
-
-<p>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.</p>
-
-<p>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:</p>
-
-<p><blockquote><pre>
-% 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
-%
-</pre></blockquote></p>
-
-<p>The fix was to add "audio/x-rosegarden;" at the end of the
-MimeType= line.</p>
-
-<p>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
-<tt>file --mime-type</tt> 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. :)</p>

- <div class="date">28th May 2016</div>
- <div class="body"><p>A little more than 11 years ago, one of the creators of Tor, and
-the current President of <a href="https://www.torproject.org/">the Tor
-project</a>, Roger Dingledine, gave a talk for the members of the
-<a href="http://www.nuug.no/">Norwegian Unix User group</a> (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
-<a href="http://frikanalen.no/se">watch the live stream using a web
-browser</a> with WebM support, or check out the recording on the video
-on demand page for the talk
-"<a href="http://beta.frikanalen.no/video/625599">Tor: Anonymous
-communication for the US Department of Defence...and you.</a>".</p>
-
-<p>Here is the video included for those of you using browsers with
-HTML video and Ogg Theora support:</p>

-
-<p>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. :)</p>

+ <div class="date">27th June 2017</div>
+ <div class="body"><p>Jeg kom over teksten
+«<a href="https://freedom-to-tinker.com/2017/06/21/killing-car-privacy-by-federal-mandate/">Killing
+car privacy by federal mandate</a>» 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.
+
+<p>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
+«<a href="https://www.sintef.no/publikasjoner/publikasjon/Download/?pubid=SINTEF+A23933">Informasjonssikkerhet
+i AutoPASS-brikker</a>» av Trond Foss:</p>
+
+<p><blockquote>
+«Rapporten ser ikke på informasjonssikkerhet knyttet til personlig
+ integritet.»
+</blockquote></p>
+
+<p>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.</p>
