-      <div class="body"><p>A while back I received a Gyro sensor for the NXT
-<a href="mindstorms.lego.com">Mindstorms</a> 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
-<a href="http://www.nxtprograms.com/NXT2/segway/">a simple balancing
-robot</a> 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,

-gyro sensor from HiTechnic</a> I believed would solve it on my
-wishlist for some years before it suddenly showed up as a gift from my
-loved ones. :)</p>
-
-<p>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
-<a href="http://www.hitechnic.com/blog/gyro-sensor/htway/">the
-HTWay</a>, a segway like balancing robot.  Build instructions and
-<a href="https://www.hitechnic.com/upload/786-HTWayC.nxc">source
-code</a> 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:</p>

-
-<p>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:</p>

-
-<p>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.</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>

-
-<blockquote>
-
-<p>Jeg ble veldig glad over å lese at Forbrukerrådet
-<a href="http://www.forbrukerradet.no/siste-nytt/klager-inn-aktivitetsarmband-for-brudd-pa-norsk-lov/">klager
-inn flere aktivitetsbånd til Datatilsynet for dårlige vilkår</a>.  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 <em>ikke</em> sender informasjon til
-skyen, men derimot bruker
-<a href="http://people.skolelinux.org/pere/blog/Fri_og__pen_standard__slik_Digistan_ser_det.html">en
-fritt og åpent standardisert</a> 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.</p>
-
-<p>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.</p>
-
-<p>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?</p>
-
-</blockquote>
-
-<p>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.</p>

+
+<p>There are two commercial services available,

+<a href="https://overleaf.com">Overleaf</a>.  They are very easy to
+use.  Just start a new document, select which publisher to write for

+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

+<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

+
+<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

-      <div class="date">10th October 2016</div>
-      <div class="body"><p>In July
-<a href="http://people.skolelinux.org/pere/blog/How_to_use_the_Signal_app_if_you_only_have_a_land_line__ie_no_mobile_phone_.html">I
-wrote how to get the Signal Chrome/Chromium app working</a> without
-the ability to receive SMS messages (aka without a cell phone).  It is
-time to share some experiences and provide an updated setup.</p>
-
-<p>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 <tt>userdata/</tt> 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 'reset session' 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.</p>
-
-<p>I'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.</p>
-
-<p>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 'Register without mobile phone' to get going
-now.  I've also modified the timeout code to always set it to 90 days
-in the future, to avoid having to patch the code regularly.</p>
-
-<p>So, the updated recipe for Debian Jessie:</p>
-
-<ol>
-
-<li>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.
-
-<pre>
-apt install git tor chromium
-git clone https://github.com/WhisperSystems/Signal-Desktop.git
-</pre></li>
-
-<li>Modify the source code using command listed in the the patch
-block below.</li>

+      <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>:

 
 

-<li>Start Signal using the run-signal-app wrapper (for example using
-<tt>`pwd`/run-signal-app</tt>).
-
-<li>Click on the 'Register without mobile phone', 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
-'Register'.  Note, the phone number you use will be user Signal
-username, ie the way others can find you on Signal.</li>
+<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>

 
 

-<li>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.</li>
+<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>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
-<a href="https://github.com/LibreSignal/LibreSignal/issues/37">the
-LibreSignal issue tracker</a> 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 <a href="https://ring.cx/">Ring</a>
-once it <a href="https://bugs.debian.org/830265">work on my
-laptop</a>?  It already work on Windows and Android, and is included
-in <a href="https://tracker.debian.org/pkg/ring">Debian</a> and
-<a href="https://launchpad.net/ubuntu/+source/ring">Ubuntu</a>, but not
-working on Debian Stable.</p>
-
-<p>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:</p>
-

-      <div class="date"> 8th October 2016</div>
-      <div class="body"><p>NRK
-<a href="https://nrkbeta.no/2016/09/02/securing-whistleblowers/">lanserte
-for noen uker siden</a> en ny
-<a href="https://www.nrk.no/varsle/">varslerportal som bruker
-SecureDrop til å ta imot tips</a> 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 "Nyhetstips som ikke krever denne
-typen ekstra vern vil vi gjerne ha på nrk.no/03030", og 03030-siden
-foreslår i tillegg til et webskjema å bruke epost, SMS, telefon,
-personlig oppmøte og brevpost.  Denne artikkelen handler disse andre
-metodene.</p>
-
-<p>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 "nrk-no.mail.protection.outlook.com".  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
-<tt>traceroute</tt>, 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).</p>
-
-<p>Vi vet fra
-<a href="https://no.wikipedia.org/wiki/FRA-loven">introduksjonen av
-FRA-loven</a> 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
-<a href="https://www.theguardian.com/world/2013/jul/11/microsoft-nsa-collaboration-user-data">samarbeider
-med USAs etterretning på flere områder</a>.  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.</p>
-
-<p>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.</p>
-
-<p>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).</p>
-
-<p>Personlig oppmøte hos en NRK-journalist er antagelig det tryggeste,
-men en bør passe seg for å bruke NRK-kantina.  Der bryter de nemlig
-<a href="http://www.lovdata.no/all/hl-19850524-028.html#14">Sentralbanklovens
-paragraf 14</a> 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 & 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.</p>
-
-<p>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 "i skyen" (eller
-andre folks datamaskiner, som det jo innebærer), så jeg vet ikke hvor
-lenge det i så fall vil vare.</p>
-
-<p>I tillegg vet en jo at
-<a href="https://www.nrk.no/ytring/elektronisk-kildevern-i-nrk-1.11941196">NRK
-har valgt å gi nasjonal sikkerhetsmyndighet (NSM) tilgang til å se på
-intern og ekstern Internett-trafikk</a> hos NRK ved oppsett av såkalte
-VDI-noder, på tross av
-<a href="https://www.nrk.no/ytring/bekymring-for-nrks-kildevern-1.11941584">protester
-fra NRKs journalistlag</a>.  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.</p>
-
-<p>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.</p>

-      <div class="date"> 7th October 2016</div>
-      <div class="body"><p><a href="http://packages.qa.debian.org/isenkram">The Isenkram
-system</a> provide a practical and easy way to figure out which
-packages support the hardware in a given machine.  The command line
-tool <tt>isenkram-lookup</tt> 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 <tt>pcscd</tt> if
-that package isn't already installed, and if you plug in a USB video
-camera the system will ask if you want to install <tt>cheese</tt> if
-cheese is currently missing.  This already work just fine.</p>
-
-<p>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.</p>
-
-<p>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.</p>
-
-<p>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
-<a href="http://people.skolelinux.org/pere/blog/Using_appstream_with_isenkram_to_install_hardware_related_packages_in_Debian.html">a
-recipe on how to add such meta-information</a> in a blog post last
-December.  If you have a hardware related package in Debian, please
-announce the relevant hardware IDs using AppStream.</p>
-
-<p>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.</p>
-
-<p>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 <tt>/lib/udev/rules.d/70-udev-acl.rules</tt>
-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.</p>
-
-<p>The new system uses a udev tag, 'uaccess'.  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
-<tt>/lib/udev/rules.d/60-nqc.rules</tt> file now look like this:
-
-<p><pre>
-SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="0694", ATTR{idProduct}=="0001", \
-    SYMLINK+="rcx-%k", TAG+="uaccess"
-</pre></p>
-
-<p>The key part is the 'TAG+="uaccess"' 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
-<tt>70-uaccess.rules</tt>).  Perhaps a lintian check should be created
-to detect this?</p>
-
-<p>I'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
-<tt>/lib/udev/rules.d/70-udev-acl.rules</tt>.  If it is, I guess the
-indirect method is the preferred way.  Michael
-<a href="https://github.com/systemd/systemd/issues/4288">asked for more
-documentation from the systemd project</a> and I hope it will make
-this clearer.  For now I use the generic classes when they exist and
-is already handled by <tt>70-uaccess.rules</tt>, and add the tag
-directly if no such class exist.</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"> 6th September 2016</div>
-      <div class="body"><p>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
-<a href="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">forslag
-om at e-tjenesten skal få lov til a avlytte all Internett-trafikk</a>
-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.</p>
-
-<p>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.</p
-
-<p>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 <a href="http://ipinfo.io/">ipinfo.io</a>
-for å få en ide om hvor i verden en IP-adresse hører til.</p>
-
-<p>På den positive siden vil forslaget gjøre at enda flere blir
-motivert til å ta grep for å bruke
-<a href="https://www.torproject.org/">Tor</a> og krypterte
-kommunikasjonsløsninger for å kommunisere med sine kjære, for å sikre
-at privatsfæren vernes.  Selv bruker jeg blant annet
-<a href="https://www.freedomboxfoundation.org/">FreedomBox</a> og
-<a href="https://whispersystems.org/">Signal</a> til slikt.  Ingen av
-dem er optimale, men de fungerer ganske bra allerede og øker kostnaden
-for dem som ønsker å invadere mitt privatliv.</p>
-
-<p>For øvrig burde varsleren Edward Snowden få politisk asyl i
-Norge.</p>

+      <div class="date">29th September 2017</div>
+      <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
+<a href="https://github.com/Oros42/IMSI-catcher/issues/14">the github
+issue for the topic</a>.
+
+<p>If this sound interesting, visit the stand at the festival!</p>

+<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="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 &lt;coz.h&gt; and insert the
-COZ_PROGRESS or COZ_BEGIN and COZ_END at appropriate places in the
-code, rebuild and run the profiler.  This allow coz to do more
-targeted experiments.</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

-      <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>
-
-<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>

+      <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>
