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.

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.

Personally, I would recommend to completely remove your Facebook account, and take back some control of your personal information. According to The Guardian, it is a bit hard to find out how to request account removal (and not just 'disabling'). You need to visit a specific Facebook page and click on 'let us know' on that page to get to the real account deletion screen. 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.

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 NUUG last april about Data collection, psychometric profiling and their impact on politics.

And if you want to communicate with your friends and loved ones, use some end-to-end encrypted method like Signal or Ring, and stop sharing your private messages with strangers like Facebook and Google.

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. Stortingets flertallsinnstilling er at tidsbegrensingen skal fjernes, og mener at tidsubegrenset lagring ikke vil påvirke oppslutningen om undersøkelsen.

Datatilsynet har ikke akkurat applaudert forslaget:

«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.»

Det er flere historier om hvordan innsamlet biologisk materiale har blitt brukt til andre formål enn de ble innsamlet til, og historien om folkehelseinstituttets lagring på vegne av politiet (Kripos) av innsamlet biologisk materiale og DNA-informasjon i strid med loven 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.

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 folkehelseinstituttets websider, 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.

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.

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.

Yesterday, after many months of hard work by several volunteer translators, the first draft of a Norwegian Bokmål edition of the book Made with Creative Commons from 2017 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.

The whole book project started when Gunnar Wolf announced 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 Free Culture and The Debian Administrator's Handbook 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.

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.

The translation is conducted using the Weblate web based translation system. Please have a look there and get in touch if you would like to help out with proof reading. :)

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:

While I am happy to see Debian used more places, some details of the content on the screen worries me.

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 Debian version history on Wikpedia. This mean the system is running around 10 year old code, with no security fixes from the vendor for many years.

This is not the first time I discover the Oslo subway company, Ruter, running outdated software. In 2012, I discovered the ticket vending machines were running Windows 2000, and this was still the case in 2016. 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.

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. The upstream project still exist, though, and up until today, the upstream source was available from Savannah via subversion. I am happy to report that this just changed.

The upstream source is now in Git, and consist of three repositories:

• sysvinit
• insserv
• startpar

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.

A few days ago, a new major version of VLC was announced, and I decided to check out if it now supported streaming over bittorrent and webtorrent. Bittorrent is one of the most efficient ways to distribute large files on the Internet, and Webtorrent is a variant of Bittorrent using WebRTC 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 the release notes 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 ("Open Source Giant VLC Mulls BitTorrent Streaming Support"), 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 VLC plugin to add bittorrent support, created by Johan Gunnarsson in 2016/2017. Again according to Jean-Babtiste, this is not the patch he was talking about.

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 The Internet Archive using VLC commands like this:

vlc https://archive.org/download/LoveNest/LoveNest_archive.torrent

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.

I have created a request for a new package in Debian (RFP) and asked if the upstream author is willing to help make this happen. 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.

I have not found any traces of webtorrent support for VLC.

A new version of the 3D printer slicer software Cura, version 3.1.0, is now available in Debian Testing (aka Buster) and Debian Unstable (aka Sid). I hope you find it useful. It was uploaded the last few days, and the last update will enter testing tomorrow. See the release notes for the list of bug fixes and new features. Version 3.2 was announced 6 days ago. We will try to get it into Debian as well.

More information related to 3D printing is available on the 3D printing and 3D printer wiki pages in Debian.

Jeg lar meg fascinere av en artikkel i Dagbladet om Kinas håndtering av Xinjiang, spesielt følgende utsnitt:

«I den sørvestlige byen Kashgar nærmere grensa til Sentral-Asia meldes det nå at 120.000 uigurer er internert i såkalte omskoleringsleirer. Samtidig er det innført et omfattende helsesjekk-program med innsamling og lagring av DNA-prøver fra absolutt alle innbyggerne. De mest avanserte overvåkingsmetodene testes ut her. Programmer for å gjenkjenne ansikter og stemmer er på plass i regionen. Der har de lokale myndighetene begynt å installere GPS-systemer i alle kjøretøy og egne sporingsapper i mobiltelefoner.

Politimetodene griper så dypt inn i folks dagligliv at motstanden mot Beijing-regimet øker.»

Beskrivelsen avviker jo desverre ikke så veldig mye fra tilstanden her i Norge.

I Norge har jo situasjonen rundt Folkehelseinstituttets lagring av DNA-informasjon på vegne av politiet, der de nektet å slette informasjon politiet ikke hadde lov til å ta vare på, gjort det klart at DNA tar vare på ganske lenge. I tillegg finnes det utallige biobanker som lagres til evig tid, og det er planer om å innføre evig lagring av DNA-materiale fra alle spebarn som fødes (med mulighet for å be om sletting).

I Norge er det system på plass for ansiktsgjenkjenning, som en NRK-artikkel fra 2015 forteller er aktiv på Gardermoen, samt brukes til å analysere bilder innsamlet av myndighetene. Brukes det også flere plasser? Det er tett med overvåkningskamera kontrollert av politi og andre myndigheter i for eksempel Oslo sentrum.

Jeg er ikke kjent med at Norge har noe system for identifisering av personer ved hjelp av stemmegjenkjenning.

Posisjons-sporing av mobiltelefoner er ruinemessig tilgjengelig for blant annet politi, NAV og Finanstilsynet, i tråd med krav i telefonselskapenes konsesjon. I tillegg rapporterer smarttelefoner sin posisjon til utviklerne av utallige mobil-apper, der myndigheter og andre kan hente ut informasjon ved behov. Det er intet behov for noen egen app for dette.

Posisjons-sporing av biler er rutinemessig tilgjengelig via et tett nett av målepunkter på veiene (automatiske bomstasjoner, køfribrikke-registrering, automatiske fartsmålere og andre veikamera). Det er i tillegg vedtatt at alle nye biler skal selges med utstyr for GPS-sporing (eCall).

Det er jammen godt vi lever i et liberalt demokrati, og ikke en overvåkningsstat, eller?

We write 2018, and it is 30 years since Unicode was introduced. Most of us in Norway have come to expect the use of our alphabet to just work with any computer system. But it is apparently beyond reach of the computers printing recites at a restaurant. Recently I visited a Peppes pizza resturant, and noticed a few details on the recite. Notice how 'ø' and 'å' are replaced with strange symbols in 'Servitør', 'Å BETALE', 'Beløp pr. gjest', 'Takk for besøket.' and 'Vi gleder oss til å se deg igjen'.

I would say that this state is passed sad and over in embarrassing.

I removed personal and private information to be nice.

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 Retro Film Vault, there are 44,000 public domain films, so I guess there are still some left to identify.

The complete data set is available from a public git repository, 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.

Anyway, this is the summary of the 28 collected data sources so far:

 2352 entries (   66 unique) with and 15983 without IMDB title ID in free-movies-archive-org-search.json
 2302 entries (  120 unique) with and     0 without IMDB title ID in free-movies-archive-org-wikidata.json

  698 entries (   64 unique) with and   118 without IMDB title ID in free-movies-publicdomaintorrents.json
 1758 entries (  882 unique) with and  3786 without IMDB title ID in free-movies-retrofilmvault.json
   16 entries (    0 unique) with and     0 without IMDB title ID in free-movies-thehillproductions.json
   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

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.
