-<p>Several of these research papers are based on data collected from
-hundred thousands or millions of disk, and their findings are eye
-opening. The short story is simply do not implicitly trust RAID or
-redundant storage systems. Details matter. And unfortunately there
-are few options on Linux addressing all the identified issues. Both
-ZFS and Btrfs are doing a fairly good job, but have legal and
-practical issues on their own. I wonder how cluster file systems like
-Ceph do in this regard. After, all the old saying, you know you have
-a distributed system when the crash of a compyter you have never heard
-of stops you from getting any work done. The same holds true if fault
-tolerance do not work.</p>
-
-<p>Just remember, in the end, it do not matter how redundant, or how
-fault tolerant your storage is, if you do not continuously monitor its
-status to detect and replace failed disks.</p>

+ <div class="date">21st March 2018</div>
+ <div class="body"><p>So, Cambridge Analytica is getting some well deserved criticism for
+(mis)using information it got from Facebook about 50 million people,
+mostly in the USA. What I find a bit surprising, is how little
+criticism Facebook is getting for handing the information over to
+Cambridge Analytica and others in the first place. And what about the
+people handing their private and personal information to Facebook?
+And last, but not least, what about the government offices who are
+handing information about the visitors of their web pages to Facebook?
+No-one who looked at the terms of use of Facebook should be surprised
+that information about peoples interests, political views, personal
+lifes and whereabouts would be sold by Facebook.</p>
+
+<p>What I find to be the real scandal is the fact that Facebook is
+selling your personal information, not that one of the buyers used it
+in a way Facebook did not approve when exposed. It is well known that
+Facebook is selling out their users privacy, but a scandal
+nevertheless. Of course the information provided to them by Facebook
+would be misused by one of the parties given access to personal
+information about the millions of Facebook users. Collected
+information will be misused sooner or later. The only way to avoid
+such misuse, is to not collect the information in the first place. If
+you do not want Facebook to hand out information about yourself for
+the use and misuse of its customers, do not give Facebook the
+information.</p>
+
+<p>Personally, I would recommend to completely remove your Facebook
+account, and take back some control of your personal information.
+<a href="https://www.theguardian.com/technology/2018/mar/19/how-to-protect-your-facebook-privacy-or-delete-yourself-completely">According
+to The Guardian</a>, it is a bit hard to find out how to request
+account removal (and not just 'disabling'). You need to
+<a href="https://www.facebook.com/help/224562897555674?helpref=faq_content">visit
+a specific Facebook page</a> and click on 'let us know' on that page
+to get to <a href="https://www.facebook.com/help/delete_account">the
+real account deletion screen</a>. Perhaps something to consider? I
+would not trust the information to really be deleted (who knows,
+perhaps NSA, GCHQ and FRA already got a copy), but it might reduce the
+exposure a bit.</p>
+
+<p>If you want to learn more about the capabilities of Cambridge
+Analytica, I recommend to see the video recording of the one hour talk
+Paul-Olivier Dehaye gave to <a href="">NUUG</a> last april about
+<a href="https://www.nuug.no/aktiviteter/20170404-big-data-psychometric/">
+Data collection, psychometric profiling and their impact on
+politics</a>.</p>
+
+<p>And if you want to communicate with your friends and loved ones,
+use some end-to-end encrypted method like
+<a href="https://www.signal.org/">Signal</a> or
+<a href="https://ring.cx/">Ring</a>, and stop sharing your private
+messages with strangers like Facebook and Google.</p>

- <div class="date">31st October 2017</div>
- <div class="body"><p>I was surprised today to learn that a friend in academia did not
-know there are easily available web services available for writing
-LaTeX documents as a team. I thought it was common knowledge, but to
-make sure at least my readers are aware of it, I would like to mention
-these useful services for writing LaTeX documents. Some of them even
-provide a WYSIWYG editor to ease writing even further.</p>
-
-<p>There are two commercial services available,
-<a href="https://sharelatex.com">ShareLaTeX</a> and
-<a href="https://overleaf.com">Overleaf</a>. They are very easy to
-use. Just start a new document, select which publisher to write for
-(ie which LaTeX style to use), and start writing. Note, these two
-have announced their intention to join forces, so soon it will only be
-one joint service. I've used both for different documents, and they
-work just fine. While
-<a href="https://github.com/sharelatex/sharelatex">ShareLaTeX is free
-software</a>, while the latter is not. According to <a
-href="https://www.overleaf.com/help/17-is-overleaf-open-source">a
-announcement from Overleaf</a>, they plan to keep the ShareLaTeX code
-base maintained as free software.</p>
-
-But these two are not the only alternatives.
-<a href="https://app.fiduswriter.org/">Fidus Writer</a> is another free
-software solution with <a href="https://github.com/fiduswriter">the
-source available on github</a>. I have not used it myself. Several
-others can be found on the nice
-<a href="https://alternativeto.net/software/sharelatex/">alterntiveTo
-web service</a>.
-
-<p>If you like Google Docs or Etherpad, but would like to write
-documents in LaTeX, you should check out these services. You can even
-host your own, if you want to. :)</p>

+ <div class="date">14th March 2018</div>
+ <div class="body"><p>I går kom det nok et argument for å holde seg unna det norske
+helsevesenet. Da annonserte et stortingsflertall, bestående av Høyre,
+Arbeiderpartiet, Fremskrittspartiet og Venstre, at de går inn for å
+samle inn og lagre DNA-prøver fra hele befolkningen i Norge til evig
+tid. Endringen gjelder innsamlede blodprøver fra nyfødte i Norge.
+Det vil dermed ta litt tid før en har hele befolkningen, men det er
+dit vi havner gitt nok tid. I dag er det nesten hundre prosent
+oppslutning om undersøkelsen som gjøres like etter fødselen, på
+bakgrunn av blodprøven det er snakk om å lagre, for å oppdage endel
+medfødte sykdommer. Blodprøven lagres i dag i inntil seks år.
+<a href="https://www.stortinget.no/no/Saker-og-publikasjoner/Publikasjoner/Innstillinger/Stortinget/2017-2018/inns-201718-182l/?all=true">Stortingets
+flertallsinnstilling</a> er at tidsbegrensingen skal fjernes, og mener
+at tidsubegrenset lagring ikke vil påvirke oppslutningen om
+undersøkelsen.</p>
+
+<p>Datatilsynet har ikke akkurat applaudert forslaget:</p>
+
+<p><blockquote>
+
+ <p>«Datatilsynet mener forslaget ikke i tilstrekkelig grad
+ synliggjør hvilke etiske og personvernmessige utfordringer som må
+ diskuteres før en etablerer en nasjonal biobank med blodprøver fra
+ hele befolkningen.»</p>
+
+</blockquote></p>
+
+<p>Det er flere historier om hvordan innsamlet biologisk materiale har
+blitt brukt til andre formål enn de ble innsamlet til, og historien om
+<a href="https://www.aftenposten.no/norge/i/Ql0WR/Na-ma-Folkehelsa-slette-uskyldiges-DNA-info">folkehelseinstituttets
+lagring på vegne av politiet (Kripos) av innsamlet biologisk materiale
+og DNA-informasjon i strid med loven</a> viser at en ikke kan være
+trygg på at lover og intensjoner beskytter de som blir berørt mot
+misbruk av slik privat og personlig informasjon.</p>
+
+<p>Det er verdt å merke seg at det kan forskes på de innsamlede
+blodprøvene uten samtykke fra den det gjelder (eller foreldre når det
+gjelder barn), etter en lovendring for en stund tilbake, med mindre
+det er sendt inn skjema der en reserverer seg mot forskning uten
+samtykke. Skjemaet er tilgjengelig fra
+<a href="https://www.fhi.no/arkiv/publikasjoner/for-pasienter-skjema-for-reservasjo/">folkehelseinstituttets
+websider</a>, og jeg anbefaler, uavhengig av denne saken, varmt alle å
+sende inn skjemaet for å dokumentere hvor mange som ikke synes det er
+greit å fjerne krav om samtykke.</p>
+
+<p>I tillegg bør en kreve destruering av alt biologisk materiale som
+er samlet inn om en selv, for å redusere eventuelle negative
+konsekvenser i fremtiden når materialet kommer på avveie eller blir
+brukt uten samtykke, men det er så vidt jeg vet ikke noe system for
+dette i dag.</p>
+
+<p>Som vanlig, hvis du bruker Bitcoin og ønsker å vise din støtte til
+det jeg driver med, setter jeg pris på om du sender Bitcoin-donasjoner
+til min adresse

- <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 70 "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>

+ <div class="date">13th March 2018</div>
+ <div class="body"><p>I am working on publishing yet another book related to Creative
+Commons. This time it is a book filled with interviews and histories
+from those around the globe making a living using Creative
+Commons.</p>
+
+<p>Yesterday, after many months of hard work by several volunteer
+translators, the first draft of a Norwegian Bokmål edition of the book
+<a href="https://madewith.cc">Made with Creative Commons from 2017</a>
+was complete. The Spanish translation is also complete, while the
+Dutch, Polish, German and Ukraine edition need a lot of work. Get in
+touch if you want to help make those happen, or would like to
+translate into your mother tongue.</p>
+
+<p>The whole book project started when
+<a href="http://gwolf.org/node/4102">Gunnar Wolf announced</a> that he
+was going to make a Spanish edition of the book. I noticed, and
+offered some input on how to make a book, based on my experience with
+translating the
+<a href="https://www.lulu.com/shop/lawrence-lessig/fri-kultur/paperback/product-22441576.html">Free
+Culture</a> and
+<a href="https://debian-handbook.info/get/#norwegian">The Debian
+Administrator's Handbook</a> books to Norwegian Bokmål. To make a
+long story short, we ended up working on a Bokmål edition, and now the
+first rough translation is complete, thanks to the hard work of
+Ole-Erik Yrvin, Ingrid Yrvin, Allan Nordhøy and myself. The first
+proof reading is almost done, and only the second and third proof
+reading remains. We will also need to translate the 14 figures and
+create a book cover. Once it is done we will publish the book on
+paper, as well as in PDF, ePub and possibly Mobi formats.</p>
+
+<p>The book itself originates as a manuscript on Google Docs, is
+downloaded as ODT from there and converted to Markdown using pandoc.
+The Markdown is modified by a script before is converted to DocBook
+using pandoc. The DocBook is modified again using a script before it
+is used to create a Gettext POT file for translators. The translated
+PO file is then combined with the earlier mentioned DocBook file to
+create a translated DocBook file, which finally is given to dblatex to
+create the final PDF. The end result is a set of editions of the
+manuscript, one English and one for each of the translations.</p>
+
+<p>The translation is conducted using
+<a href="https://hosted.weblate.org/projects/madewithcc/translation/">the
+Weblate web based translation system</a>. Please have a look there
+and get in touch if you would like to help out with proof
+reading. :)</p>

-the proposed border wall between USA and Mexico support the idea. The
-proposal to keep Mexicans out reminds me of
-<a href="http://www.history.com/news/10-things-you-may-not-know-about-the-berlin-wall">the

-the “Antifascist Bulwark” after erecting the Berlin Wall, claiming
-that the wall was erected to keep enemies from creeping into East
-Germany, while it was obvious to the people locked inside it that it
-was erected to keep the people from escaping.</p>
-
-<p>Do the people in USA supporting this wall really believe it is a
-one way wall, only keeping people on the outside from getting in,
-while not keeping people in the inside from getting out?</p>
+ <div class="title"><a href="http://people.skolelinux.org/pere/blog/Debian_used_in_the_subway_info_screens_in_Oslo__Norway.html">Debian used in the subway info screens in Oslo, Norway</a></div>
+ <div class="date"> 2nd March 2018</div>
+ <div class="body"><p>Today I was pleasantly surprised to discover my operating system of
+choice, Debian, was used in the info screens on the subway stations.
+While passing Nydalen subway station in Oslo, Norway, I discovered the
+info screen booting with some text scrolling. I was not quick enough
+with my camera to be able to record a video of the scrolling boot
+screen, but I did get a photo from when the boot got stuck with a
+corrupt file system:
+
+<p align="center"><a href="http://people.skolelinux.org/pere/blog/images/2018-03-02-ruter-debian-lenny.jpeg"><img align="center" width="40%" src="http://people.skolelinux.org/pere/blog/images/2018-03-02-ruter-debian-lenny.jpeg" alt="[photo of subway info screen]"></a></p>
+
+<p>While I am happy to see Debian used more places, some details of the
+content on the screen worries me.</p>
+
+<p>The image show the version booting is 'Debian GNU/Linux lenny/sid',
+indicating that this is based on code taken from Debian Unstable/Sid
+after Debian Etch (version 4) was released 2007-04-08 and before
+Debian Lenny (version 5) was released 2009-02-14. Since Lenny Debian
+has released version 6 (Squeeze) 2011-02-06, 7 (Wheezy) 2013-05-04, 8
+(Jessie) 2015-04-25 and 9 (Stretch) 2017-06-15, according to
+<a href="https://en.wikipedia.org/wiki/Debian_version_history">a Debian
+version history on Wikpedia</a>. This mean the system is running
+around 10 year old code, with no security fixes from the vendor for
+many years.</p>
+
+<p>This is not the first time I discover the Oslo subway company,
+Ruter, running outdated software. In 2012,
+<a href="http://people.skolelinux.org/pere/blog/Er_billettautomatene_til_kollektivtrafikken_i_Oslo_uten_sikkerhetsoppdateringer_.html">I
+discovered the ticket vending machines were running Windows 2000</a>,
+and this was
+<a href="http://people.skolelinux.org/pere/blog/Fortsatt_ingen_sikkerhetsoppdateringer_for_billettautomatene_til_kollektivtrafikken_i_Oslo_.html">still
+the case in 2016</a>. Given the response from the responsible people
+in 2016, I would assume the machines are still running unpatched
+Windows 2000. Thus, an unpatched Debian setup come as no surprise.</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>

+ <div class="date">18th February 2018</div>
+ <div class="body"><p>Surprising as it might sound, there are still computers using the
+traditional Sys V init system, and there probably will be until
+systemd start working on Hurd and FreeBSD.
+<a href="https://savannah.nongnu.org/projects/sysvinit">The upstream
+project still exist</a>, though, and up until today, the upstream
+source was available from Savannah via subversion. I am happy to
+report that this just changed.</p>
+
+<p>The upstream source is now in Git, and consist of three
+repositories:</p>
+
+<ul>
+
+<li><a href="http://git.savannah.nongnu.org/cgit/sysvinit.git">sysvinit</a></li>

+
+</ul>
+
+<p>I do not really spend much time on the project these days, and I
+has mostly retired, but found it best to migrate the source to a good
+version control system to help those willing to move it forward.</p>

+ <div class="date">14th February 2018</div>
+ <div class="body"><p>A few days ago, a new major version of
+<a href="https://www.videolan.org/">VLC</a> was announced, and I
+decided to check out if it now supported streaming over
+<a href="http://bittorrent.org/">bittorrent</a> and
+<a href="https://webtorrent.io">webtorrent</a>. Bittorrent is one of
+the most efficient ways to distribute large files on the Internet, and
+Webtorrent is a variant of Bittorrent using
+<a href="https://webrtc.org">WebRTC</a> as its transport channel,
+allowing web pages to stream and share files using the same technique.
+The network protocols are similar but not identical, so a client
+supporting one of them can not talk to a client supporting the other.
+I was a bit surprised with what I discovered when I started to look.
+Looking at
+<a href="https://www.videolan.org/vlc/releases/3.0.0.html">the release
+notes</a> did not help answering this question, so I started searching
+the web. I found several news articles from 2013, most of them
+tracing the news from Torrentfreak
+("<a href=https://torrentfreak.com/open-source-giant-vlc-mulls-bittorrent-support-130211/">Open
+Source Giant VLC Mulls BitTorrent Streaming Support</a>"), about a
+initiative to pay someone to create a VLC patch for bittorrent
+support. To figure out what happend with this initiative, I headed
+over to the #videolan IRC channel and asked if there were some bug or
+feature request tickets tracking such feature. I got an answer from
+lead developer Jean-Babtiste Kempf, telling me that there was a patch
+but neither he nor anyone else knew where it was. So I searched a bit
+more, and came across an independent
+<a href="https://github.com/johang/vlc-bittorrent">VLC plugin to add
+bittorrent support</a>, created by Johan Gunnarsson in 2016/2017.
+Again according to Jean-Babtiste, this is not the patch he was talking
+about.</p>
+
+<p>Anyway, to test the plugin, I made a working Debian package from
+the git repository, with some modifications. After installing this
+package, I could stream videos from
+<a href="https://www.archive.org/">The Internet Archive</a> using VLC
+commands like this:</p>
+
+<p><blockquote><pre>
+vlc https://archive.org/download/LoveNest/LoveNest_archive.torrent
+</pre></blockquote></p>
+
+<p>The plugin is supposed to handle magnet links too, but since The
+Internet Archive do not have magnet links and I did not want to spend
+time tracking down another source, I have not tested it. It can take
+quite a while before the video start playing without any indication of
+what is going on from VLC. It took 10-20 seconds when I measured it.
+Some times the plugin seem unable to find the correct video file to
+play, and show the metadata XML file name in the VLC status line. I
+have no idea why.</p>
+
+<p>I have created a <a href="https://bugs.debian.org/890360">request for
+a new package in Debian (RFP)</a> and
+<a href="https://github.com/johang/vlc-bittorrent/issues/1">asked if
+the upstream author is willing to help make this happen</a>. Now we
+wait to see what come out of this. I do not want to maintain a
+package that is not maintained upstream, nor do I really have time to
+maintain more packages myself, so I might leave it at this. But I
+really hope someone step up to do the packaging, and hope upstream is
+still maintaining the source. If you want to help, please update the
+RFP request or the upstream issue.</p>
+
+<p>I have not found any traces of webtorrent support for VLC.</p>

- <div class="body"><p>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.</p>
-
-<p>I am very happy to report that we managed to get something
-visualizing this information up and running for
-<a href="http://norwaymakers.org/osf17">Oslo Skaperfestival 2017</a>
-(Oslo Makers Festival) taking place today and tomorrow at Deichmanske
-library. The solution is based on the
-<a href="http://people.skolelinux.org/pere/blog/Easier_recipe_to_observe_the_cell_phones_around_you.html">simple
-recipe for listening to GSM chatter</a> I posted a few days ago, and
-will show up at the stand of <a href="http://sonen.ifi.uio.no/">Åpen
-Sone from the Computer Science department of the University of
-Oslo</a>. 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.</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
-Hopglass</a>. A fairly powerfull machine is needed as the
-grgsm_livemon_headless processes from
-<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="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>

+<p>I Norge har jo situasjonen rundt Folkehelseinstituttets lagring av

+at DNA tar vare på ganske lenge. I tillegg finnes det utallige

+
+<p>Jeg er ikke kjent med at Norge har noe system for identifisering av

+
+<p>Posisjons-sporing av mobiltelefoner er ruinemessig tilgjengelig for

-<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"> 7th January 2018</div>
+ <div class="body"><p>I've continued to track down list of movies that are legal to
+distribute on the Internet, and identified more than 11,000 title IDs
+in The Internet Movie Database (IMDB) so far. Most of them (57%) are
+feature films from USA published before 1923. I've also tracked down
+more than 24,000 movies I have not yet been able to map to IMDB title
+ID, so the real number could be a lot higher. According to the front
+web page for <a href="https://retrofilmvault.com/">Retro Film
+Vault</A>, there are 44,000 public domain films, so I guess there are
+still some left to identify.</p>
+
+<p>The complete data set is available from
+<a href="https://github.com/petterreinholdtsen/public-domain-free-imdb">a
+public git repository</a>, including the scripts used to create it.
+Most of the data is collected using web scraping, for example from the
+"product catalog" of companies selling copies of public domain movies,
+but any source I find believable is used. I've so far had to throw
+out three sources because I did not trust the public domain status of
+the movies listed.</p>
+
+<p>Anyway, this is the summary of the 28 collected data sources so
+far:</p>
+
+<p><pre>

+ 63 entries ( 16 unique) with and 141 without IMDB title ID in free-movies-vodo.json
+11583 unique IMDB title IDs in total, 8724 only in one list, 24647 without IMDB title ID
+</pre></p>
+
+<p> I keep finding more data sources. I found the cinemovies source
+just a few days ago, and as you can see from the summary, it extended
+my list with 63 movies. Check out the mklist-* scripts in the git
+repository if you are curious how the lists are created. Many of the
+titles are extracted using searches on IMDB, where I look for the
+title and year, and accept search results with only one movie listed
+if the year matches. This allow me to automatically use many lists of
+movies without IMDB title ID references at the cost of increasing the
+risk of wrongly identify a IMDB title ID as public domain. So far my
+random manual checks have indicated that the method is solid, but I
+really wish all lists of public domain movies would include unique
+movie identifier like the IMDB title ID. It would make the job of
+counting movies in the public domain a lot easier.</p>
