+      <div class="date">13th August 2018</div>
+      <div class="body"><p>A few days ago, I wondered if there are any privacy respecting
+health monitors and/or fitness trackers available for sale these days.
+I would like to buy one, but do not want to share my personal data
+with strangers, nor be forced to have a mobile phone to get data out
+of the unit.  I've received some ideas, and would like to share them
+with you.
+
+One interesting data point was a pointer to a Free Software app for
+Android named
+<a href="https://github.com/Freeyourgadget/Gadgetbridge/">Gadgetbridge</a>.
+It provide cloudless collection and storing of data from a variety of
+trackers.  Its
+<a href="https://github.com/Freeyourgadget/Gadgetbridge/#supported-devices">list
+of supported devices</a> is a good indicator for units where the
+protocol is fairly open, as it is obviously being handled by Free
+Software.  Other units are reportedly encrypting the collected
+information with their own public key, making sure only the vendor
+cloud service is able to extract data from the unit.  The people
+contacting me about Gadgetbirde said they were using
+<a href="https://us.amazfit.com/shop/bip?variant=336750">Amazfit
+Bip</a> and
+<a href="http://www.xiaomimi6phone.com/xiaomi-mi-band-3-features-release-date-rumors/">Xiaomi
+Band 3</a>.</p>
+
+<p>I also got a suggestion to look at some of the units from Garmin.
+I was told their GPS watches can be connected via USB and show up as a
+USB storage device with
+<a href="https://www.gpsbabel.org/htmldoc-development/fmt_garmin_fit.html">Garmin
+FIT files</a> containing the collected measurements.  While
+proprietary, FIT files apparently can be read at least by
+<a href="https://www.gpsbabel.org">GPSBabel</a> and the
+<a href="https://apps.nextcloud.com/apps/gpxpod">GpxPod</a> Nextcloud
+app.  It is unclear to me if they can read step count and heart rate
+data.  The person I talked to was using a
+<a href="https://buy.garmin.com/en-US/US/p/564291">Garmin Forerunner
+935</a>, which is a fairly expensive unit.  I doubt it is worth it for
+a unit where the vendor clearly is trying its best to move from open
+to closed systems.  I still remember when Garmin dropped NMEA support
+in its GPSes.</p>
+
+<p>A final idea was to build ones own unit, perhaps by basing it on a
+wearable hardware platforms like
+<a href="https://learn.adafruit.com/flora-geo-watch">the Flora Geo
+Watch</a>.  Sound like fun, but I had more money than time to spend on
+the topic, so I suspect it will have to wait for another time.</p>
+
+<p>While I was working on tracking down links, I came across an
+inspiring TED talk by Dave Debronkart about
+<a href="https://archive.org/details/DavedeBronkart_2010X">being a
+e-patient</a>, and discovered the web site
+<a href="https://participatorymedicine.org/epatients/">Participatory
+Medicine</a>.  If you too want to track your own health and fitness
+without having information about your private life floating around on
+computers owned by others, I recommend checking it out.</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>

+      <div class="date">31st July 2018</div>
+      <div class="body"><p>For a while now, I have looked for a sensible way to share images
+with my family using a self hosted solution, as it is unacceptable to
+place images from my personal life under the control of strangers
+working for data hoarders like Google or Dropbox.  The last few days I
+have drafted an approach that might work out, and I would like to
+share it with you.  I would like to publish images on a server under
+my control, and point some Internet connected display units using some
+free and open standard to the images I published.  As my primary
+language is not limited to ASCII, I need to store metadata using
+UTF-8.  Many years ago, I hoped to find a digital photo frame capable
+of reading a RSS feed with image references (aka using the
+&lt;enclosure&gt; RSS tag), but was unable to find a current supplier
+of such frames.  In the end I gave up that approach.</p>
+
+<p>Some months ago, I discovered that
+<a href="https://www.jwz.org/xscreensaver/">XScreensaver</a> is able to
+read images from a RSS feed, and used it to set up a screen saver on
+my home info screen, showing images from the Daily images feed from
+NASA.  This proved to work well.  More recently I discovered that
+<a href="https://kodi.tv">Kodi</a> (both using
+<a href="https://www.openelec.tv/">OpenELEC</a> and
+<a href="https://libreelec.tv">LibreELEC</a>) provide the
+<a href="https://github.com/grinsted/script.screensaver.feedreader">Feedreader</a>
+screen saver capable of reading a RSS feed with images and news.  For
+fun, I used it this summer to test Kodi on my parents TV by hooking up
+a Raspberry PI unit with LibreELEC, and wanted to provide them with a
+screen saver showing selected pictures from my selection.</p>
+
+<p>Armed with motivation and a test photo frame, I set out to generate
+a RSS feed for the Kodi instance.  I adjusted my <a
+href="https://freedombox.org/">Freedombox</a> instance, created
+/var/www/html/privatepictures/, wrote a small Perl script to extract
+title and description metadata from the photo files and generate the
+RSS file.  I ended up using Perl instead of python, as the
+libimage-exiftool-perl Debian package seemed to handle the EXIF/XMP
+tags I ended up using, while python3-exif did not.  The relevant EXIF
+tags only support ASCII, so I had to find better alternatives.  XMP
+seem to have the support I need.</p>
+
+<p>I am a bit unsure which EXIF/XMP tags to use, as I would like to
+use tags that can be easily added/updated using normal free software
+photo managing software.  I ended up using the tags set using this
+exiftool command, as these tags can also be set using digiKam:</p>
+
+<blockquote><pre>
+exiftool -headline='The RSS image title' \
+  -description='The RSS image description.' \
+  -subject+=for-family photo.jpeg
+</pre></blockquote>
+
+<p>I initially tried the "-title" and "keyword" tags, but they were
+invisible in digiKam, so I changed to "-headline" and "-subject".  I
+use the keyword/subject 'for-family' to flag that the photo should be
+shared with my family.  Images with this keyword set are located and
+copied into my Freedombox for the RSS generating script to find.</p>
+
+<p>Are there better ways to do this?  Get in touch if you have better
+suggestions.</p>

-      <div class="body"><p>I går var jeg i Follo tingrett som sakkyndig vitne og presenterte
-  mine undersøkelser rundt
-  <a href="https://github.com/petterreinholdtsen/public-domain-free-imdb">telling
-    av filmverk i det fri</a>, relatert til
-  <a href="https://www.nuug.no/">foreningen NUUG</a>s involvering i
-  <a href="https://www.nuug.no/news/tags/dns-domenebeslag/">saken om
-  Økokrims beslag og senere inndragning av DNS-domenet
-  popcorn-time.no</a>.  Jeg snakket om flere ting, men mest om min
-  vurdering av hvordan filmbransjen har målt hvor ulovlig Popcorn Time
-  er.  Filmbransjens måling er så vidt jeg kan se videreformidlet uten
-  endringer av norsk politi, og domstolene har lagt målingen til grunn
-  når de har vurdert Popcorn Time både i Norge og i utlandet (tallet
-  99% er referert også i utenlandske domsavgjørelser).</p>
-
-<p>I forkant av mitt vitnemål skrev jeg et notat, mest til meg selv,
-  med de punktene jeg ønsket å få frem.  Her er en kopi av notatet jeg
-  skrev og ga til aktoratet.  Merkelig nok ville ikke dommerene ha
-  notatet, så hvis jeg forsto rettsprosessen riktig ble kun
-  histogram-grafen lagt inn i dokumentasjonen i saken.  Dommerne var
-  visst bare interessert i å forholde seg til det jeg sa i retten,
-  ikke det jeg hadde skrevet i forkant.  Uansett så antar jeg at flere
-  enn meg kan ha glede av teksten, og publiserer den derfor her.
-  Legger ved avskrift av dokument 09,13, som er det sentrale
-  dokumentet jeg kommenterer.</p>
-
-<p><strong>Kommentarer til «Evaluation of (il)legality» for Popcorn
-  Time</strong></p>
-
-<p><strong>Oppsummering</strong></p>		
-
-<p>Målemetoden som Økokrim har lagt til grunn når de påstår at 99% av
-  filmene tilgjengelig fra Popcorn Time deles ulovlig har
-  svakheter.</p>
-
-<p>De eller den som har vurdert hvorvidt filmer kan lovlig deles har
-  ikke lyktes med å identifisere filmer som kan deles lovlig og har
-  tilsynelatende antatt at kun veldig gamle filmer kan deles lovlig.
-  Økokrim legger til grunn at det bare finnes èn film, Charlie
-  Chaplin-filmen «The Circus» fra 1928, som kan deles fritt blant de
-  som ble observert tilgjengelig via ulike Popcorn Time-varianter.
-  Jeg finner tre flere blant de observerte filmene: «The Brain That
-  Wouldn't Die» fra 1962, «God’s Little Acre» fra 1958 og «She Wore a
-  Yellow Ribbon» fra 1949.  Det er godt mulig det finnes flere.  Det
-  finnes dermed minst fire ganger så mange filmer som lovlig kan deles
-  på Internett i datasettet Økokrim har lagt til grunn når det påstås
-  at mindre enn 1 % kan deles lovlig.</p>
-
-<p>Dernest, utplukket som gjøres ved søk på tilfeldige ord hentet fra
-  ordlisten til Dale-Chall avviker fra årsfordelingen til de brukte
-  filmkatalogene som helhet, hvilket påvirker fordelingen mellom
-  filmer som kan lovlig deles og filmer som ikke kan lovlig deles.  I
-  tillegg gir valg av øvre del (de fem første) av søkeresultatene et
-  avvik fra riktig årsfordeling, hvilket påvirker fordelingen av verk
-  i det fri i søkeresultatet.</p>
-
-<p>Det som måles er ikke (u)lovligheten knyttet til bruken av Popcorn
-  Time, men (u)lovligheten til innholdet i bittorrent-filmkataloger
-  som vedlikeholdes uavhengig av Popcorn Time.</p>
-
-<p>Omtalte dokumenter: 09,12, <a href="#dok-09-13">09,13</a>, 09,14,
-09,18, 09,19, 09,20.</p>
-
-<p><strong>Utfyllende kommentarer</strong></p>
-
-<p>Økokrim har forklart domstolene at minst 99% av alt som er
-  tilgjengelig fra ulike Popcorn Time-varianter deles ulovlig på
-  Internet.  Jeg ble nysgjerrig på hvordan de er kommet frem til dette
-  tallet, og dette notatet er en samling kommentarer rundt målingen
-  Økokrim henviser til.  Litt av bakgrunnen for at jeg valgte å se på
-  saken er at jeg er interessert i å identifisere og telle hvor mange
-  kunstneriske verk som er falt i det fri eller av andre grunner kan
-  lovlig deles på Internett, og dermed var interessert i hvordan en
-  hadde funnet den ene prosenten som kanskje deles lovlig.</p>
-
-<p>Andelen på 99% kommer fra et ukreditert og udatert notatet som tar
-  mål av seg å dokumentere en metode for å måle hvor (u)lovlig ulike
-  Popcorn Time-varianter er.</p>
-
-<p>Raskt oppsummert, så forteller metodedokumentet at på grunn av at
-  det ikke er mulig å få tak i komplett liste over alle filmtitler
-  tilgjengelig via Popcorn Time, så lages noe som skal være et
-  representativt utvalg ved å velge 50 søkeord større enn tre tegn fra
-  ordlisten kjent som Dale-Chall.  For hvert søkeord gjøres et søk og
-  de første fem filmene i søkeresultatet samles inn inntil 100 unike
-  filmtitler er funnet.  Hvis 50 søkeord ikke var tilstrekkelig for å
-  nå 100 unike filmtitler ble flere filmer fra hvert søkeresultat lagt
-  til.  Hvis dette heller ikke var tilstrekkelig, så ble det hentet ut
-  og søkt på flere tilfeldig valgte søkeord inntil 100 unike
-  filmtitler var identifisert.</p>
-
-<p>Deretter ble for hver av filmtitlene «vurdert hvorvidt det var
-  rimelig å forvente om at verket var vernet av copyright, ved å se på
-  om filmen var tilgjengelig i IMDB, samt se på regissør,
-  utgivelsesår, når det var utgitt for bestemte markedsområder samt
-  hvilke produksjons- og distribusjonsselskap som var registrert» (min
-  oversettelse).</p>
-
-<p>Metoden er gjengitt både i de ukrediterte dokumentene 09,13 og
-  09,19, samt beskrevet fra side 47 i dokument 09,20, lysark datert
-  2017-02-01.  Sistnevnte er kreditert Geerart Bourlon fra Motion
-  Picture Association EMEA.  Metoden virker å ha flere svakheter som
-  gir resultatene en slagside.  Den starter med å slå fast at det ikke
-  er mulig å hente ut en komplett liste over alle filmtitler som er
-  tilgjengelig, og at dette er bakgrunnen for metodevalget.  Denne
-  forutsetningen er ikke i tråd med det som står i dokument 09,12, som
-  ikke heller har oppgitt forfatter og dato.  Dokument 09,12 forteller
-  hvordan hele kataloginnholdet ble lasted ned og talt opp.  Dokument
-  09,12 er muligens samme rapport som ble referert til i dom fra Oslo
-  Tingrett 2017-11-03
-  (<a href="https://www.domstol.no/no/Enkelt-domstol/Oslo--tingrett/Nyheter/ma-sperre-for-popcorn-time/">sak
-  17-093347TVI-OTIR/05</a>) som rapport av 1. juni 2017 av Alexander
-  Kind Petersen, men jeg har ikke sammenlignet dokumentene ord for ord
-  for å kontrollere dette.</p>
-
-<p>IMDB er en forkortelse for The Internet Movie Database, en
-  anerkjent kommersiell nettjeneste som brukes aktivt av både
-  filmbransjen og andre til å holde rede på hvilke spillefilmer (og
-  endel andre filmer) som finnes eller er under produksjon, og
-  informasjon om disse filmene.  Datakvaliteten er høy, med få feil og
-  få filmer som mangler.  IMDB viser ikke informasjon om
-  opphavsrettslig status for filmene på infosiden for hver film.  Som
-  del av IMDB-tjenesten finnes det lister med filmer laget av
-  frivillige som lister opp det som antas å være verk i det fri.</p>
-  
-<p>Det finnes flere kilder som kan brukes til å finne filmer som er
-  allemannseie (public domain) eller har bruksvilkår som gjør det
-  lovlig for alleå dele dem på Internett.  Jeg har de siste ukene
-  forsøkt å samle og krysskoble disse listene for å forsøke å telle
-  antall filmer i det fri.  Ved å ta utgangspunkt i slike lister (og
-  publiserte filmer for Internett-arkivets del), har jeg så langt
-  klart å identifisere over 11 000 filmer, hovedsaklig spillefilmer.
-
-<p>De aller fleste oppføringene er hentet fra IMDB selv, basert på det
-  faktum at alle filmer laget i USA før 1923 er falt i det fri.
-  Tilsvarende tidsgrense for Storbritannia er 1912-07-01, men dette
-  utgjør bare veldig liten del av spillefilmene i IMDB (19 totalt).
-  En annen stor andel kommer fra Internett-arkivet, der jeg har
-  identifisert filmer med referanse til IMDB.  Internett-arkivet, som
-  holder til i USA, har som
-  <a href="https://archive.org/about/terms.php">policy å kun publisere
-  filmer som det er lovlig å distribuere</a>.  Jeg har under arbeidet
-  kommet over flere filmer som har blitt fjernet fra
-  Internett-arkivet, hvilket gjør at jeg konkluderer med at folkene
-  som kontrollerer Internett-arkivet har et aktivt forhold til å kun
-  ha lovlig innhold der, selv om det i stor grad er drevet av
-  frivillige.  En annen stor liste med filmer kommer fra det
-  kommersielle selskapet Retro Film Vault, som selger allemannseide
-  filmer til TV- og filmbransjen, Jeg har også benyttet meg av lister
-  over filmer som hevdes å være allemannseie, det være seg Public
-  Domain Review, Public Domain Torrents og Public Domain Movies (.net
-  og .info), samt lister over filmer med Creative Commons-lisensiering
-  fra Wikipedia, VODO og The Hill Productions.  Jeg har gjort endel
-  stikkontroll ved å vurdere filmer som kun omtales på en liste.  Der
-  jeg har funnet feil som har gjort meg i tvil om vurderingen til de
-  som har laget listen har jeg forkastet listen fullstendig (gjelder
-  en liste fra IMDB).</p>
-  
-<p>Ved å ta utgangspunkt i verk som kan antas å være lovlig delt på
-  Internett (fra blant annet Internett-arkivet, Public Domain
-  Torrents, Public Domain Reivew og Public Domain Movies), og knytte
-  dem til oppføringer i IMDB, så har jeg så langt klart å identifisere
-  over 11 000 filmer (hovedsaklig spillefilmer) det er grunn til å tro
-  kan lovlig distribueres av alle på Internett.  Som ekstra kilder er
-  det brukt lister over filmer som antas/påstås å være allemannseie.
-  Disse kildene kommer fra miljøer som jobber for å gjøre tilgjengelig
-  for almennheten alle verk som er falt i det fri eller har
-  bruksvilkår som tillater deling.
-
-<p>I tillegg til de over 11 000 filmene der tittel-ID i IMDB er
-  identifisert, har jeg funnet mer enn 20 000 oppføringer der jeg ennå
-  ikke har hatt kapasitet til å spore opp tittel-ID i IMDB.  Noen av
-  disse er nok duplikater av de IMDB-oppføringene som er identifisert
-  så langt, men neppe alle.  Retro Film Vault hevder å ha 44 000
-  filmverk i det fri i sin katalog, så det er mulig at det reelle
-  tallet er betydelig høyere enn de jeg har klart å identifisere så
-  langt.  Konklusjonen er at tallet 11 000 er nedre grense for hvor
-  mange filmer i IMDB som kan lovlig deles på Internett.  I følge <a
-  href="http://www.imdb.com/stats">statistikk fra IMDB</a> er det 4.6
-  millioner titler registrert, hvorav 3 millioner er TV-serieepisoder.
-  Jeg har ikke funnet ut hvordan de fordeler seg per år.</p>
-
-<p>Hvis en fordeler på år alle tittel-IDene i IMDB som hevdes å lovlig
-  kunne deles på Internett, får en følgende histogram:</p>
-
-<p align="center"><img width="80%" src="http://people.skolelinux.org/pere/blog/images/2017-12-20-histogram-year.png"></p>
-
-<p>En kan i histogrammet se at effekten av manglende registrering
-  eller fornying av registrering er at mange filmer gitt ut i USA før
-  1978 er allemannseie i dag.  I tillegg kan en se at det finnes flere
-  filmer gitt ut de siste årene med bruksvilkår som tillater deling,
-  muligens på grunn av fremveksten av
-  <a href="https://creativecommons.org/">Creative
-  Commons</a>-bevegelsen..</p>
-  
-<p>For maskinell analyse av katalogene har jeg laget et lite program
-  som kobler seg til bittorrent-katalogene som brukes av ulike Popcorn
-  Time-varianter og laster ned komplett liste over filmer i
-  katalogene, noe som bekrefter at det er mulig å hente ned komplett
-  liste med alle filmtitler som er tilgjengelig.  Jeg har sett på fire
-  bittorrent-kataloger.  Den ene brukes av klienten tilgjengelig fra
-  www.popcorntime.sh og er navngitt 'sh' i dette dokumentet.  Den
-  andre brukes i følge dokument 09,12 av klienten tilgjengelig fra
-  popcorntime.ag og popcorntime.sh og er navngitt 'yts' i dette
-  dokumentet.  Den tredje brukes av websidene tilgjengelig fra
-  popcorntime-online.tv og er navngitt 'apidomain' i dette dokumentet.
-  Den fjerde brukes av klienten tilgjenglig fra popcorn-time.to i
-  følge dokument 09,12, og er navngitt 'ukrfnlge' i dette
-  dokumentet.</p>
-
-<p>Metoden Økokrim legger til grunn skriver i sitt punkt fire at
-  skjønn er en egnet metode for å finne ut om en film kan lovlig deles
-  på Internett eller ikke, og sier at det ble «vurdert hvorvidt det
-  var rimelig å forvente om at verket var vernet av copyright».  For
-  det første er det ikke nok å slå fast om en film er «vernet av
-  copyright» for å vite om det er lovlig å dele den på Internett eller
-  ikke, da det finnes flere filmer med opphavsrettslige bruksvilkår
-  som tillater deling på Internett.  Eksempler på dette er Creative
-  Commons-lisensierte filmer som Citizenfour fra 2014 og Sintel fra
-  2010.  I tillegg til slike finnes det flere filmer som nå er
-  allemannseie (public domain) på grunn av manglende registrering
-  eller fornying av registrering selv om både regisør,
-  produksjonsselskap og distributør ønsker seg vern.  Eksempler på
-  dette er Plan 9 from Outer Space fra 1959 og Night of the Living
-  Dead fra 1968.  Alle filmer fra USA som var allemannseie før
-  1989-03-01 forble i det fri da Bern-konvensjonen, som tok effekt i
-  USA på det tidspunktet, ikke ble gitt tilbakevirkende kraft.  Hvis
-  det er noe
-  <a href="http://www.latimes.com/local/lanow/la-me-ln-happy-birthday-song-lawsuit-decision-20150922-story.html">historien
-  om sangen «Happy birthday»</a> forteller oss, der betaling for bruk
-  har vært krevd inn i flere tiår selv om sangen ikke egentlig var
-  vernet av åndsverksloven, så er det at hvert enkelt verk må vurderes
-  nøye og i detalj før en kan slå fast om verket er allemannseie eller
-  ikke, det holder ikke å tro på selverklærte rettighetshavere.  Flere
-  eksempel på verk i det fri som feilklassifiseres som vernet er fra
-  dokument 09,18, som lister opp søkeresultater for klienten omtalt
-  som popcorntime.sh og i følge notatet kun inneholder en film (The
-  Circus fra 1928) som under tvil kan antas å være allemannseie.</p>
-
-<p>Ved rask gjennomlesning av dokument 09,18, som inneholder
-  skjermbilder fra bruk av en Popcorn Time-variant, fant jeg omtalt
-  både filmen «The Brain That Wouldn't Die» fra 1962 som er
-  <a href="https://archive.org/details/brain_that_wouldnt_die">tilgjengelig
-  fra Internett-arkivet</a> og som
-  <a href="https://en.wikipedia.org/wiki/List_of_films_in_the_public_domain_in_the_United_States">i
-    følge Wikipedia er allemannseie i USA</a> da den ble gitt ut i
-  1962 uten 'copyright'-merking, og filmen «God’s Little Acre» fra
-  1958 <a href="https://en.wikipedia.org/wiki/God%27s_Little_Acre_%28film%29">som
-    er lagt ut på Wikipedia</a>, der det fortelles at
-  sort/hvit-utgaven er allemannseie.  Det fremgår ikke fra dokument
-  09,18 om filmen omtalt der er sort/hvit-utgaven.  Av
-  kapasitetsårsaker og på grunn av at filmoversikten i dokument 09,18
-  ikke er maskinlesbart har jeg ikke forsøkt å sjekke alle filmene som
-  listes opp der om mot liste med filmer som er antatt lovlig kan
-  distribueres på Internet.</p>
-
-<p>Ved maskinell gjennomgang av listen med IMDB-referanser under
-  regnearkfanen 'Unique titles' i dokument 09.14, fant jeg i tillegg
-  filmen «She Wore a Yellow Ribbon» fra 1949) som nok også er
-  feilklassifisert. Filmen «She Wore a Yellow Ribbon» er tilgjengelig
-  fra Internett-arkivet og markert som allemannseie der.  Det virker
-  dermed å være minst fire ganger så mange filmer som kan lovlig deles
-  på Internett enn det som er lagt til grunn når en påstår at minst
-  99% av innholdet er ulovlig.  Jeg ser ikke bort fra at nærmere
-  undersøkelser kan avdekke flere.  Poenget er uansett at metodens
-  punkt om «rimelig å forvente om at verket var vernet av copyright»
-  gjør metoden upålitelig.</p>
-
-<p>Den omtalte målemetoden velger ut tilfeldige søketermer fra
-  ordlisten Dale-Chall.  Den ordlisten inneholder 3000 enkle engelske
-  som fjerdeklassinger i USA er forventet å forstå.  Det fremgår ikke
-  hvorfor akkurat denne ordlisten er valgt, og det er uklart for meg
-  om den er egnet til å få et representativt utvalg av filmer.  Mange
-  av ordene gir tomt søkeresultat.  Ved å simulerte tilsvarende søk
-  ser jeg store avvik fra fordelingen i katalogen for enkeltmålinger.
-  Dette antyder at enkeltmålinger av 100 filmer slik målemetoden
-  beskriver er gjort, ikke er velegnet til å finne andel ulovlig
-  innhold i bittorrent-katalogene.</p>
-
-<p>En kan motvirke dette store avviket for enkeltmålinger ved å gjøre
-  mange søk og slå sammen resultatet.  Jeg har testet ved å
-  gjennomføre 100 enkeltmålinger (dvs. måling av (100x100=) 10 000
-  tilfeldig valgte filmer) som gir mindre, men fortsatt betydelig
-  avvik, i forhold til telling av filmer pr år i hele katalogen.</p>
-  
-<p>Målemetoden henter ut de fem øverste i søkeresultatet.
-  Søkeresultatene er sortert på antall bittorrent-klienter registrert
-  som delere i katalogene, hvilket kan gi en slagside mot hvilke
-  filmer som er populære blant de som bruker bittorrent-katalogene,
-  uten at det forteller noe om hvilket innhold som er tilgjengelig
-  eller hvilket innhold som deles med Popcorn Time-klienter.  Jeg har
-  forsøkt å måle hvor stor en slik slagside eventuelt er ved å
-  sammenligne fordelingen hvis en tar de 5 nederste i søkeresultatet i
-  stedet.  Avviket for disse to metodene for endel kataloger er godt
-  synlig på histogramet.  Her er histogram over filmer funnet i den
-  komplette katalogen (grønn strek), og filmer funnet ved søk etter
-  ord i Dale-Chall.  Grafer merket 'top' henter fra de 5 første i
-  søkeresultatet, mens de merket 'bottom' henter fra de 5 siste.  En
-  kan her se at resultatene påvirkes betydelig av hvorvidt en ser på
-  de første eller de siste filmene i et søketreff.</p>

-</p>
-  
-<p>Det er verdt å bemerke at de omtalte bittorrent-katalogene ikke er
-  laget for bruk med Popcorn Time.  Eksempelvis tilhører katalogen
-  YTS, som brukes av klientet som ble lastes ned fra popcorntime.sh,
-  et selvstendig fildelings-relatert nettsted YTS.AG med et separat
-  brukermiljø.  Målemetoden foreslått av Økokrim måler dermed ikke
-  (u)lovligheten rundt bruken av Popcorn Time, men (u)lovligheten til
-  innholdet i disse katalogene.</p>

+      <div class="date">12th July 2018</div>
+      <div class="body"><p>Last night, I wrote
+<a href="http://people.skolelinux.org/pere/blog/Streaming_the_Linux_desktop_to_Kodi_using_VLC_and_RTSP.html">a
+recipe to stream a Linux desktop using VLC to a instance of Kodi</a>.
+During the day I received valuable feedback, and thanks to the
+suggestions I have been able to rewrite the recipe into a much simpler
+approach requiring no setup at all.  It is a single script that take
+care of it all.</p>
+
+<p>This new script uses GStreamer instead of VLC to capture the
+desktop and stream it to Kodi.  This fixed the video quality issue I
+saw initially.  It further removes the need to add a m3u file on the
+Kodi machine, as it instead connects to
+<a href="https://kodi.wiki/view/JSON-RPC_API/v8">the JSON-RPC API in
+Kodi</a> and simply ask Kodi to play from the stream created using
+GStreamer.  Streaming the desktop to Kodi now become trivial.  Copy
+the script below, run it with the DNS name or IP address of the kodi
+server to stream to as the only argument, and watch your screen show
+up on the Kodi screen.  Note, it depend on multicast on the local
+network, so if you need to stream outside the local network, the
+script must be modified.  Also note, I have no idea if audio work, as
+I only care about the picture part.</p>

-<p><strong>1.1. Methodology</strong>
-     
-<p>Due to its technical configuration, Popcorn Time applications don't
-allow to make a full list of all titles made available. In order to
-evaluate the level of illegal operation of PCT, the following
-methodology was applied:</p>
-
-<ol>
-
- <li>A random selection of 50 keywords, greater than 3 letters, was
-    made from the Dale-Chall list that contains 3000 simple English
-    words1. The selection was made by using a Random Number
-    Generator2.</li>
-	  
- <li>For each keyword, starting with the first randomly selected
-    keyword, a search query was conducted in the movie section of the
-    respective Popcorn Time application. For each keyword, the first
-    five results were added to the title list until the number of 100
-    unique titles was reached (duplicates were removed).</li>
-	  
- <li>For one fork, .CH, insufficient titles were generated via this
-    approach to reach 100 titles. This was solved by adding any
-    additional query results above five for each of the 50 keywords.
-    Since this still was not enough, another 42 random keywords were
-    selected to finally reach 100 titles.</li>
-	  
- <li>It was verified whether or not there is a reasonable expectation
-    that the work is copyrighted by checking if they are available on
-    IMDb, also verifying the director, the year when the title was
-    released, the release date for a certain market, the production
-    company/ies of the title and the distribution company/ies.</li>
-
-</ol>
-
-<p><strong>1.2. Results</strong></p>
-     
-<p>Between 6 and 9 June 2016, four forks of Popcorn Time were
-investigated: popcorn-time.to, popcorntime.ag, popcorntime.sh and
-popcorntime.ch. An excel sheet with the results is included in
-Appendix 1. Screenshots were secured in separate Appendixes for each
-respective fork, see Appendix 2-5.</p>
-
-<p>For each fork, out of 100, de-duplicated titles it was possible to
-retrieve data according to the parameters set out above that indicate
-that the title is commercially available. Per fork, there was 1 title
-that presumably falls within the public domain, i.e. the 1928 movie
-"The Circus" by and with Charles Chaplin.</p>
-
-<p>Based on the above it is reasonable to assume that 99% of the movie
-content of each fork is copyright protected and is made available
-illegally.</p>
-
-<p>This exercise was not repeated for TV series, but considering that
-besides production companies and distribution companies also
-broadcasters may have relevant rights, it is reasonable to assume that
-at least a similar level of infringement will be established.</p>
-
-<p>Based on the above it is reasonable to assume that 99% of all the
-content of each fork is copyright protected and are made available
-illegally.</p>

-
-<p>The work to make this happen was done by Gregor Riepl, and I was

-
-<p>The 3D printer software is maintained by the 3D printer Debian

+      <div class="date">12th July 2018</div>
+      <div class="body"><p>PS: See
+<ahref="http://people.skolelinux.org/pere/blog/Simple_streaming_the_Linux_desktop_to_Kodi_using_GStreamer_and_RTP.html">the
+followup post</a> for a even better approach.</p>
+
+<p>A while back, I was asked by a friend how to stream the desktop to
+my projector connected to Kodi.  I sadly had to admit that I had no
+idea, as it was a task I never had tried.  Since then, I have been
+looking for a way to do so, preferable without much extra software to
+install on either side.  Today I found a way that seem to kind of
+work.  Not great, but it is a start.</p>
+
+<p>I had a look at several approaches, for example
+<a href="https://github.com/mfoetsch/dlna_live_streaming">using uPnP
+DLNA as described in 2011</a>, but it required a uPnP server, fuse and
+local storage enough to store the stream locally.  This is not going
+to work well for me, lacking enough free space, and it would
+impossible for my friend to get working.</p>
+
+<p>Next, it occurred to me that perhaps I could use VLC to create a
+video stream that Kodi could play.  Preferably using
+broadcast/multicast, to avoid having to change any setup on the Kodi
+side when starting such stream.  Unfortunately, the only recipe I
+could find using multicast used the rtp protocol, and this protocol
+seem to not be supported by Kodi.</p>
+
+<p>On the other hand, the rtsp protocol is working!  Unfortunately I
+have to specify the IP address of the streaming machine in both the
+sending command and the file on the Kodi server.  But it is showing my
+desktop, and thus allow us to have a shared look on the big screen at
+the programs I work on.</p>
+
+<p>I did not spend much time investigating codeces.  I combined the
+rtp and rtsp recipes from
+<a href="https://wiki.videolan.org/Documentation:Streaming_HowTo/Command_Line_Examples/">the
+VLC Streaming HowTo/Command Line Examples</a>, and was able to get
+this working on the desktop/streaming end.</p>
+
+<blockquote><pre>
+vlc screen:// --sout \
+  '#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:rtp{dst=projector.local,port=1234,sdp=rtsp://192.168.11.4:8080/test.sdp}'
+</pre></blockquote>
+
+<p>I ssh-ed into my Kodi box and created a file like this with the
+same IP address:</p>
+
+<blockquote><pre>
+echo rtsp://192.168.11.4:8080/test.sdp \
+  > /storage/videos/screenstream.m3u
+</pre></blockquote>
+
+<p>Note the 192.168.11.4 IP address is my desktops IP address.  As far
+as I can tell the IP must be hardcoded for this to work.  In other
+words, if someone elses machine is going to do the steaming, you have
+to update screenstream.m3u on the Kodi machine and adjust the vlc
+recipe.  To get started, locate the file in Kodi and select the m3u
+file while the VLC stream is running.  The desktop then show up in my
+big screen. :)</p>
+
+<p>When using the same technique to stream a video file with audio,
+the audio quality is really bad.  No idea if the problem is package
+loss or bad parameters for the transcode.  I do not know VLC nor Kodi
+enough to tell.</p>
+
+<p><strong>Update 2018-07-12</strong>: Johannes Schauer send me a few
+succestions and reminded me about an important step.  The "screen:"
+input source is only available once the vlc-plugin-access-extra
+package is installed on Debian.  Without it, you will see this error
+message: "VLC is unable to open the MRL 'screen://'.  Check the log
+for details."  He further found that it is possible to drop some parts
+of the VLC command line to reduce the amount of hardcoded information.
+It is also useful to consider using cvlc to avoid having the VLC
+window in the desktop view.  In sum, this give us this command line on
+the source end
+
+<blockquote><pre>
+cvlc screen:// --sout \
+  '#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:rtp{sdp=rtsp://:8080/}'
+</pre></blockquote>
+
+<p>and this on the Kodi end<p>
+
+<blockquote><pre>
+echo rtsp://192.168.11.4:8080/ \
+  > /storage/videos/screenstream.m3u
+</pre></blockquote>
+
+<p>Still bad image quality, though.  But I did discover that streaming
+a DVD using dvdsimple:///dev/dvd as the source had excellent video and
+audio quality, so I guess the issue is in the input or transcoding
+parts, not the rtsp part.  I've tried to change the vb and ab
+parameters to use more bandwidth, but it did not make a
+difference.</p>
+
+<p>I further received a suggestion from Einar Haraldseid to try using
+gstreamer instead of VLC, and this proved to work great!  He also
+provided me with the trick to get Kodi to use a multicast stream as
+its source.  By using this monstrous oneliner, I can stream my desktop
+with good video quality in reasonable framerate to the 239.255.0.1
+multicast address on port 1234:
+
+<blockquote><pre>
+gst-launch-1.0 ximagesrc use-damage=0 ! video/x-raw,framerate=30/1 ! \
+  videoconvert ! queue2 ! \
+  x264enc bitrate=8000 speed-preset=superfast tune=zerolatency qp-min=30 \
+  key-int-max=15 bframes=2 ! video/x-h264,profile=high ! queue2 ! \
+  mpegtsmux alignment=7 name=mux ! rndbuffersize max=1316 min=1316 ! \
+  udpsink host=239.255.0.1 port=1234 ttl-mc=1 auto-multicast=1 sync=0 \
+  pulsesrc device=$(pactl list | grep -A2 'Source #' | \
+    grep 'Name: .*\.monitor$' |  cut -d" " -f2|head -1) ! \
+  audioconvert ! queue2 ! avenc_aac ! queue2 ! mux.
+</pre></blockquote>
+
+<p>and this on the Kodi end<p>
+
+<blockquote><pre>
+echo udp://@239.255.0.1:1234 \
+  > /storage/videos/screenstream.m3u
+</pre></blockquote>
+
+<p>Note the trick to pick a valid pulseaudio source.  It might not
+pick the one you need.  This approach will of course lead to trouble
+if more than one source uses the same multicast port and address.
+Note the ttl-mc=1 setting, which limit the multicast packages to the
+local network.  If the value is increased, your screen will be
+broadcasted further, one network "hop" for each increase (read up on
+multicast to learn more. :)!</p>
+
+<p>Having cracked how to get Kodi to receive multicast streams, I
+could use this VLC command to stream to the same multicast address.
+The image quality is way better than the rtsp approach, but gstreamer
+seem to be doing a better job.</p>
+
+<blockquote><pre>
+cvlc screen:// --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:rtp{mux=ts,dst=239.255.0.1,port=1234,sdp=sap}'

-      <div class="date">13th December 2017</div>
-      <div class="body"><p>While looking at
-<a href="http://onlinebooks.library.upenn.edu/cce/">the scanned copies
-for the copyright renewal entries for movies published in the USA</a>,
-an idea occurred to me.  The number of renewals are so few per year, it
-should be fairly quick to transcribe them all and add references to
-the corresponding IMDB title ID.  This would give the (presumably)
-complete list of movies published 28 years earlier that did _not_
-enter the public domain for the transcribed year.  By fetching the
-list of USA movies published 28 years earlier and subtract the movies
-with renewals, we should be left with movies registered in IMDB that
-are now in the public domain.  For the year 1955 (which is the one I
-have looked at the most), the total number of pages to transcribe is
-21.  For the 28 years from 1950 to 1978, it should be in the range
-500-600 pages.  It is just a few days of work, and spread among a
-small group of people it should be doable in a few weeks of spare
-time.</p>
-
-<p>A typical copyright renewal entry look like this (the first one
-listed for 1955):</p>
-
-<p><blockquote>
-  ADAM AND EVIL, a photoplay in seven reels by Metro-Goldwyn-Mayer
-  Distribution Corp. (c) 17Aug27; L24293. Loew's Incorporated (PWH);
-  10Jun55; R151558.
-</blockquote></p>
-
-<p>The movie title as well as registration and renewal dates are easy
-enough to locate by a program (split on first comma and look for
-DDmmmYY).  The rest of the text is not required to find the movie in
-IMDB, but is useful to confirm the correct movie is found.  I am not
-quite sure what the L and R numbers mean, but suspect they are
-reference numbers into the archive of the US Copyright Office.</p>
-
-<p>Tracking down the equivalent IMDB title ID is probably going to be
-a manual task, but given the year it is fairly easy to search for the
-movie title using for example
-<a href="http://www.imdb.com/find?q=adam+and+evil+1927&s=all">http://www.imdb.com/find?q=adam+and+evil+1927&s=all</a>.
-Using this search, I find that the equivalent IMDB title ID for the
-first renewal entry from 1955 is
-<a href="http://www.imdb.com/title/tt0017588/">http://www.imdb.com/title/tt0017588/</a>.</p>
-
-<p>I suspect the best way to do this would be to make a specialised
-web service to make it easy for contributors to transcribe and track
-down IMDB title IDs.  In the web service, once a entry is transcribed,
-the title and year could be extracted from the text, a search in IMDB
-conducted for the user to pick the equivalent IMDB title ID right
-away.  By spreading out the work among volunteers, it would also be
-possible to make at least two persons transcribe the same entries to
-be able to discover any typos introduced.  But I will need help to
-make this happen, as I lack the spare time to do all of this on my
-own.  If you would like to help, please get in touch.  Perhaps you can
-draft a web service for crowd sourcing the task?</p>
-
-<p>Note, Project Gutenberg already have some
-<a href="http://www.gutenberg.org/ebooks/search/?query=copyright+office+renewals">transcribed
-copies of the US Copyright Office renewal protocols</a>, but I have
-not been able to find any film renewals there, so I suspect they only
-have copies of renewal for written works.  I have not been able to find
-any transcribed versions of movie renewals so far.  Perhaps they exist
-somewhere?</p>
-
-<p>I would love to figure out methods for finding all the public
-domain works in other countries too, but it is a lot harder.  At least
-for Norway and Great Britain, such work involve tracking down the
-people involved in making the movie and figuring out when they died.
-It is hard enough to figure out who was part of making a movie, but I
-do not know how to automate such procedure without a registry of every
-person involved in making movies and their death year.</p>

+analysing the desktop files in all packages in the archive.  Since
+then, the DEP-11 AppStream system has been put into production, making
+the task a lot easier.  This made me want to repeat the measurement,
+to see how much things changed.  Here are the new numbers, for
+unstable only this time:
+
+<p><strong>Debian Unstable:</strong></p>

+
+<p>It is interesting to see how image formats have passed text/plain
+as the most announced supported MIME type.  These days, thanks to the
+AppStream system, if you run into a file format you do not know, and
+want to figure out which packages support the format, you can find the
+MIME type of the file using "file --mime &lt;filename&gt;", and then
+look up all packages announcing support for this format in their
+AppStream metadata (XML or .desktop file) using "appstreamcli
+what-provides mimetype &lt;mime-type&gt;.  For example if you, like
+me, want to know which packages support inode/directory, you can get a
+list like this:</p>
+
+<p><blockquote><pre>
+% appstreamcli what-provides mimetype inode/directory | grep Package: | sort
+Package: anjuta

+</pre></blockquote></p>
+
+<p>Using the same method, I can quickly discover that the Sketchup file
+format is not yet supported by any package in Debian:</p>
+
+<p><blockquote><pre>
+% appstreamcli what-provides mimetype  application/vnd.sketchup.skp
+Could not find component providing 'mimetype::application/vnd.sketchup.skp'.

-time it was discovered, it was generally assumed to be copyrighted by
-The Walt Disney Company, and I blogged about
-<a href="http://people.skolelinux.org/pere/blog/Opphavsretts_status_for__Empty_Socks__fra_1927_.html">my
-reasoning to conclude</a> that it would would enter the Norwegian

-Norwegian Copyright Law.  But a few days ago, I came across
-<a href="http://www.toonzone.net/forums/threads/exposed-disneys-repurchase-of-oswald-the-rabbit-a-sham.4792291/">a
-blog post claiming the movie was already in the public domain</a>, at
-least in USA.  The reasoning is as follows: The film was released in
-November or Desember 1927 (sources disagree), and presumably
-registered its copyright that year.  At that time, right holders of
-movies registered by the copyright office received government
-protection for there work for 28 years.  After 28 years, the copyright
-had to be renewed if the wanted the government to protect it further.
-The blog post I found claim such renewal did not happen for this
-movie, and thus it entered the public domain in 1956.  Yet someone
-claim the copyright was renewed and the movie is still copyright
-protected.  Can anyone help me to figure out which claim is correct?
-I have not been able to find Empty Socks in Catalog of copyright
-entries.  Ser.3 pt.12-13 v.9-12 1955-1958 Motion Pictures

+      <div class="date"> 8th July 2018</div>
+      <div class="body"><p>Quite regularly, I let my Debian Sid/Unstable chroot stay untouch
+for a while, and when I need to update it there is not enough free
+space on the disk for apt to do a normal 'apt upgrade'.  I normally
+would resolve the issue by doing 'apt install &lt;somepackages&gt;' to
+upgrade only some of the packages in one batch, until the amount of
+packages to download fall below the amount of free space available.
+Today, I had about 500 packages to upgrade, and after a while I got
+tired of trying to install chunks of packages manually.  I concluded
+that I did not have the spare hours required to complete the task, and
+decided to see if I could automate it.  I came up with this small
+script which I call 'apt-in-chunks':</p>
+
+<p><blockquote><pre>
+#!/bin/sh
+#
+# Upgrade packages when the disk is too full to upgrade every
+# upgradable package in one lump.  Fetching packages to upgrade using
+# apt, and then installing using dpkg, to avoid changing the package
+# flag for manual/automatic.
+
+set -e
+
+ignore() {
+    if [ "$1" ]; then
+	grep -v "$1"
+    else
+	cat
+    fi
+}
+
+for p in $(apt list --upgradable | ignore "$@" |cut -d/ -f1 | grep -v '^Listing...'); do
+    echo "Upgrading $p"
+    apt clean
+    apt install --download-only -y $p
+    for f in /var/cache/apt/archives/*.deb; do
+	if [ -e "$f" ]; then
+	    dpkg -i /var/cache/apt/archives/*.deb
+	    break
+	fi
+    done
+done
+</pre></blockquote></p>
+
+<p>The script will extract the list of packages to upgrade, try to
+download the packages needed to upgrade one package, install the
+downloaded packages using dpkg.  The idea is to upgrade packages
+without changing the APT mark for the package (ie the one recording of
+the package was manually requested or pulled in as a dependency).  To
+use it, simply run it as root from the command line.  If it fail, try
+'apt install -f' to clean up the mess and run the script again.  This
+might happen if the new packages conflict with one of the old
+packages.  dpkg is unable to remove, while apt can do this.</p>
+
+<p>It take one option, a package to ignore in the list of packages to
+upgrade.  The option to ignore a package is there to be able to skip
+the packages that are simply too large to unpack.  Today this was
+'ghc', but I have run into other large packages causing similar
+problems earlier (like TeX).</p>
+
+<p>Update 2018-07-08: Thanks to Paul Wise, I am aware of two
+alternative ways to handle this.  The "unattended-upgrades
+--minimal-upgrade-steps" option will try to calculate upgrade sets for
+each package to upgrade, and then upgrade them in order, smallest set
+first.  It might be a better option than my above mentioned script.
+Also, "aptutude upgrade" can upgrade single packages, thus avoiding
+the need for using "dpkg -i" in the script above.</p>

-      <div class="title"><a href="http://people.skolelinux.org/pere/blog/Metadata_proposal_for_movies_on_the_Internet_Archive.html">Metadata proposal for movies on the Internet Archive</a></div>
-      <div class="date">28th November 2017</div>
-      <div class="body"><p>It would be easier to locate the movie you want to watch in
-<a href="https://www.archive.org/">the Internet Archive</a>, if the
-metadata about each movie was more complete and accurate.  In the
-archiving community, a well known saying state that good metadata is a
-love letter to the future.  The metadata in the Internet Archive could
-use a face lift for the future to love us back.  Here is a proposal
-for a small improvement that would make the metadata more useful
-today.  I've been unable to find any document describing the various
-standard fields available when uploading videos to the archive, so
-this proposal is based on my best quess and searching through several
-of the existing movies.</p>
-
-<p>I have a few use cases in mind.  First of all, I would like to be
-able to count the number of distinct movies in the Internet Archive,
-without duplicates.  I would further like to identify the IMDB title
-ID of the movies in the Internet Archive, to be able to look up a IMDB
-title ID and know if I can fetch the video from there and share it
-with my friends.</p>
-
-<p>Second, I would like the Butter data provider for The Internet
-archive
-(<a href="https://github.com/butterproviders/butter-provider-archive">available
-from github</a>), to list as many of the good movies as possible.  The
-plugin currently do a search in the archive with the following
-parameters:</p>
-
-<p><pre>
-collection:moviesandfilms
-AND NOT collection:movie_trailers
-AND -mediatype:collection
-AND format:"Archive BitTorrent"
-AND year
-</pre></p>
-
-<p>Most of the cool movies that fail to show up in Butter do so
-because the 'year' field is missing.  The 'year' field is populated by
-the year part from the 'date' field, and should be when the movie was
-released (date or year).  Two such examples are
-<a href="https://archive.org/details/SidneyOlcottsBen-hur1905">Ben Hur
-from 1905</a> and
-<a href="https://archive.org/details/Caminandes2GranDillama">Caminandes
-2: Gran Dillama from 2013</a>, where the year metadata field is
-missing.</p>
-
-So, my proposal is simply, for every movie in The Internet Archive
-where an IMDB title ID exist, please fill in these metadata fields
-(note, they can be updated also long after the video was uploaded, but
-as far as I can tell, only by the uploader):
-
-<dl>
-
-<dt>mediatype</dt>
-<dd>Should be 'movie' for movies.</dd>
-
-<dt>collection</dt>
-<dd>Should contain 'moviesandfilms'.</dd>
-
-<dt>title</dt>
-<dd>The title of the movie, without the publication year.</dd>
-
-<dt>date</dt>
-<dd>The data or year the movie was released.  This make the movie show
-up in Butter, as well as make it possible to know the age of the
-movie and is useful to figure out copyright status.</dd>
-
-<dt>director</dt>
-<dd>The director of the movie.  This make it easier to know if the
-correct movie is found in movie databases.</dd>
-
-<dt>publisher</dt>
-<dd>The production company making the movie.  Also useful for
-identifying the correct movie.</dd>
-
-<dt>links</dt>
-
-<dd>Add a link to the IMDB title page, for example like this: &lt;a
-href="http://www.imdb.com/title/tt0028496/"&gt;Movie in
-IMDB&lt;/a&gt;.  This make it easier to find duplicates and allow for
-counting of number of unique movies in the Archive.  Other external
-references, like to TMDB, could be added like this too.</dd>
-
-</dl>
-
-<p>I did consider proposing a Custom field for the IMDB title ID (for
-example 'imdb_title_url', 'imdb_code' or simply 'imdb', but suspect it
-will be easier to simply place it in the links free text field.</p>
-
-<p>I created
-<a href="https://github.com/petterreinholdtsen/public-domain-free-imdb">a
-list of IMDB title IDs for several thousand movies in the Internet
-Archive</a>, but I also got a list of several thousand movies without
-such IMDB title ID (and quite a few duplicates).  It would be great if
-this data set could be integrated into the Internet Archive metadata
-to be available for everyone in the future, but with the current
-policy of leaving metadata editing to the uploaders, it will take a
-while before this happen.  If you have uploaded movies into the
-Internet Archive, you can help.  Please consider following my proposal
-above for your movies, to ensure that movie is properly
-counted. :)</p>
-
-<p>The list is mostly generated using wikidata, which based on
-Wikipedia articles make it possible to link between IMDB and movies in
-the Internet Archive.  But there are lots of movies without a
-Wikipedia article, and some movies where only a collection page exist
-(like for <a href="https://en.wikipedia.org/wiki/Caminandes">the
-Caminandes example above</a>, where there are three movies but only
-one Wikidata entry).</p>

-
-<p>So far I have identified 3186 unique IMDB title IDs.  To gain

-
-<pre>
-  249 entries (    6 unique) with and   288 without IMDB title ID in free-movies-archive-org-butter.json
- 2301 entries (  540 unique) with and     0 without IMDB title ID in free-movies-archive-org-wikidata.json
-  830 entries (   29 unique) with and     0 without IMDB title ID in free-movies-icheckmovies-archive-mochard.json
- 2109 entries (  377 unique) with and     0 without IMDB title ID in free-movies-imdb-pd.json
-  291 entries (  122 unique) with and     0 without IMDB title ID in free-movies-letterboxd-pd.json
-  144 entries (  135 unique) with and     0 without IMDB title ID in free-movies-manual.json
-  350 entries (    1 unique) with and   801 without IMDB title ID in free-movies-publicdomainmovies.json
-    4 entries (    0 unique) with and   124 without IMDB title ID in free-movies-publicdomainreview.json
-  698 entries (  119 unique) with and   118 without IMDB title ID in free-movies-publicdomaintorrents.json
-    8 entries (    8 unique) with and   196 without IMDB title ID in free-movies-vodo.json
- 3186 unique IMDB title IDs in total
-</pre>
-
-<p>The entries without IMDB title ID are candidates to increase the
-data set, but might equally well be duplicates of entries already
-listed with IMDB title ID in one of the other sources, or represent
-movies that lack a IMDB title ID.  I've seen examples of all these
-situations when peeking at the entries without IMDB title ID.  Based
-on these data sources, the lower bound for movies listed in IMDB that
-are legal to distribute on the Internet is between 3186 and 4713.
-
-<p>It would be great for improving the accuracy of this measurement,
-if the various sources added IMDB title ID to their metadata.  I have
-tried to reach the people behind the various sources to ask if they
-are interested in doing this, without any replies so far.  Perhaps you
-can help me get in touch with the people behind VODO, Public Domain
-Torrents, Public Domain Movies and Public Domain Review to try to
-convince them to add more metadata to their movie entries?</p>
-
-<p>Another way you could help is by adding pages to Wikipedia about
-movies that are legal to distribute on the Internet.  If such page

+<a href="https://openelec.tv">OpenELEC</a> (probably soon to be
+replaced with <a href="https://libreelec.tv/">LibreELEC</a>) and an
+Infocus IN76 video projector.  My projector can be controlled via both
+a infrared remote controller, and a RS-232 serial line.  The vendor of
+my projector, <a href="https://www.infocus.com/">InFocus</a>, had been
+sensible enough to document the serial protocol in its user manual, so
+it is easily available, and I used it some years ago to write
+<a href="https://github.com/petterreinholdtsen/infocus-projector-control">a
+small script to control the projector</a>.  For a while now, I longed
+for a setup where the projector was controlled by Kodi, for example in
+such a way that when the screen saver went on, the projector was
+turned off, and when the screen saver exited, the projector was turned
+on again.</p>
+
+<p>A few days ago, with very good help from parts of my family, I
+managed to find a Kodi Add-on for controlling a Epson projector, and
+got in touch with its author to see if we could join forces and make a
+Add-on with support for several projectors.  To my pleasure, he was
+positive to the idea, and we set out to add InFocus support to his
+add-on, and make the add-on suitable for the official Kodi add-on
+repository.</p>
+
+<p>The Add-on is now working (for me, at least), with a few minor
+adjustments.  The most important change I do relative to the master
+branch in the github repository is embedding the
+<a href="https://github.com/pyserial/pyserial">pyserial module</a> in
+the add-on.  The long term solution is to make a "script" type
+pyserial module for Kodi, that can be pulled in as a dependency in
+Kodi.  But until that in place, I embed it.</p>
+
+<p>The add-on can be configured to turn on the projector when Kodi
+starts, off when Kodi stops as well as turn the projector off when the
+screensaver start and on when the screesaver stops.  It can also be
+told to set the projector source when turning on the projector.
+
+<p>If this sound interesting to you, check out
+<a href="https://github.com/fredrik-eriksson/kodi_projcontrol">the
+project github repository</a>.  Perhaps you can send patches to
+support your projector too?  As soon as we find time to wrap up the
+latest changes, it should be available for easy installation using any
+Kodi instance.</p>
+
+<p>For future improvements, I would like to add projector model
+detection and the ability to adjust the brightness level of the
+projector from within Kodi.  We also need to figure out how to handle
+the cooling period of the projector.  My projector refuses to turn on
+for 60 seconds after it was turned off.  This is not handled well by
+the add-on at the moment.</p>
