I forrige uke var jeg i Borgarting lagmannsrett som partshjelper og + sakkyndig vitne og presenterte mine oppdaterte undersøkelser rundt + telling + av filmverk i det fri, relatert til + foreningen NUUGs involvering i saken om + Ãkokrims beslag og senere inndragning av DNS-domenet + popcorn-time.no. I forkant hadde jeg oppdatert mitt notat med + kommentarer til et av aktors bevis, som forsøkte Ã¥ mÃ¥le hvor stor + andel ulovligheter som var tilgjengelig via Popcorn Time-avspillere. + Jeg mistenker flere kan ha glede av Ã¥ lese dette notatet, som jeg + publiserte en tidligere versjon av i fjor, sÃ¥ her er det. Legger + ogsÃ¥ ved avskrift av dokument 09,13, som er det sentrale dokumentet + jeg kommenterer.
+ +Oppdaterte kommentarer til «Evaluation of (il)legality» for +Popcorn Time
+ +Oppsummering
+ +MÃ¥lemetoden som Ãkokrim har lagt til grunn nÃ¥r de pÃ¥stÃ¥r at 99% av + filmene tilgjengelig fra Popcorn Time deles ulovlig har svakheter + som gjør resultatet upÃ¥litelig.
+ +De eller den som har vurdert hvorvidt filmer kan lovlig deles er + ikke i stand til Ã¥ identifisere filmer som kan deles lovlig eller er + falt i det fri og har tilsynelatende antatt at kun veldig gamle + filmer kan deles lovlig. Ãkokrim 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. Med min begrensede og ufullstendige oversikt finner + jeg tre flere blant de observerte filmene: «The Brain That Wouldn't + Die» fra 1962, «Godâs 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 sÃ¥ mange filmer som lovlig kan deles pÃ¥ + Internett i datasettet Ãkokrim har lagt til grunn nÃ¥r det pÃ¥stÃ¥s at + mindre enn 1 % kan deles lovlig.
+ +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.
+ +Til sist er det viktig å merke seg at det som måles er ikke + (u)lovligheten knyttet til bruken av Popcorn Time, + men (u)lovligheten til innholdet i ulike bittorrent-filmkataloger + som vedlikeholdes av ulike miljøer uavhengig av Popcorn Time, og som + ulike Popcorn Time-varianter har benyttet seg av.
+ +Omtalte dokumenter: 09,12, 09,13, 09,14, + 09,18, 09,19, 09,20.
+ +Utfyllende kommentarer
+ +Ãkokrim har forklart domstolene at minst 99% av alt som er + tilgjengelig fra ulike Popcorn Time-varianter deles ulovlig pÃ¥ + Internet. Jeg ble nysgjerrig pÃ¥ hvordan de er kommet frem til dette + tallet, og dette notatet er en samling kommentarer rundt mÃ¥lingen + Ãkokrim henviser til. Litt av bakgrunnen for at jeg valgte Ã¥ se pÃ¥ + saken er at jeg er interessert i Ã¥ identifisere og telle hvor mange + kunstneriske verk som er falt i det fri eller av andre grunner kan + lovlig deles pÃ¥ Internett, og dermed var interessert i hvordan en + hadde funnet den ene prosenten som kanskje deles lovlig.
+ +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.
+ +Raskt oppsummert, så forteller metodedokumentet at fordi 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 tilfeldige søkeord større enn tre tegn fra en + ordliste 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.
+ +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).
+ +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 i en bittorrent-katalog ble lasted ned og talt + opp. Dokument 09,12 er muligens samme rapport som det ble referert + til i dom fra Oslo Tingrett 2017-11-03 + (sak + 17-093347TVI-OTIR/05) under navnet rapport av 1. juni 2017 av + Alexander Kind Petersen. De ligner, men jeg har ikke sammenlignet + dokumentene ord for ord for å kontrollere om de er identiske.
+ +Det finnes flere kilder som kan brukes til å finne filmer som er + allemannseie (public domain) eller har bruksvilkår som gjør det + lovlig for alle å dele dem på Internett. Jeg har det siste året + forsøkt å samle og krysskoble disse listene ved hjelp av tittel-ID i + IMDB 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 + 14 000 filmer, hovedsaklig spillefilmer. Noen filmer er gått tapt + ved at de eneste kjente eksemplarene er blitt ødelagt. Jeg har ikke + forsøkt å finne ut hvilke filmer som er gått tapt, ut over å se + hvilke filmer som er tilgjengelig på filmdelings-nettsteder.
+ +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, samt + 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, men + frivillige har lagt ut på IMDB-tjenesten lister med filmer som antas + å være verk i det fri. Disse listene er en liten del av kildene for + min telling av verk som kan lovlig deles på Internett.
+ +De aller fleste oppføringene over verk i det fri 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 som har referanse + til IMDB. Internett-arkivet, som holder til i USA, har + som policy å kun + publisere filmer som det er lovlig å distribuere. 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 kun å + ha lovlig innhold der, selv om det i stor grad er drevet av + frivillige. Internett-arkivet har publisert 4.6 millioner + videofilmer som samtlige er tilgjengelig også med + Bittorrent-protokollen. 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 (to ulike tjenester med samme navn, på .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 for eksemel en av + listene fra IMDB).
+ +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 14 000 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.
+ +I tillegg til de over 14 000 filmene der tittel-ID i IMDB er + identifisert, har jeg funnet mer enn 26 000 oppføringer der jeg ennå + ikke har hatt kapasitet til å spore opp tittel-ID i IMDB. Jeg har + sett at noen av disse er duplikater av de IMDB-oppføringene som er + identifisert så langt, men de fleste jeg har hatt tid til å + undersøke så langt har vist seg å ikke være duplikater. 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 en kan trekke fra dette er at + tallet 14 000 er nedre grense for hvor mange filmer i IMDB som kan + lovlig deles på Internett. I + følge statistikk fra IMDB + er det 4.6 millioner titler registrert, hvorav 3 millioner er + TV-serieepisoder.
+ +Hvis en fordeler på år alle tittel-IDene i IMDB som hevdes å deles + lovlig på Internett, får en følgende histogram:
+ +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 Creative + Commons-bevegelsen.
+ +IMDB har lagt ut en + maskinlesbare liste over alle registreringene i sin database, og + ved hjelp av denne har jeg oppsummert antall titler per år i + kategoriene «movies» og «short», som er det jeg fokuserer på i min + telling. Inn i oversikten er det tegnet hvor stor prosentandel + antallet filmer som hevdes å kunne deles lovlig på Internett utgjør + av IMDB-totalen. Ut fra oversikten får man en ide om hvor stor andel + av totalen som kan mangle i min telling, for eksempel ved å merke + seg at få prosenter av filmene utgitt tidlig på 1900-tallet er med i + min telling.
+ +For maskinell analyse av katalogene laget jeg 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. Dette bekrefter at det er mulig å hente ut komplett + liste med alle filmtitler som er tilgjengelig i katalogene, i strid + med påstanden i dokumentene 09,13, 09,19 og 09,20. Jeg har sett på + fire bittorrent-kataloger. Den ene ble brukt av klienten + tilgjengelig fra www.popcorntime.sh 2017-12-18 og er navngitt «sh» i + dette dokumentet. Den andre brukes i følge dokument 09,12 av + klienten tilgjengelig fra popcorntime.ag og popcorntime.sh på ukjent + tidspunkt og er navngitt «yts» i dette dokumentet. Den tredje ble + brukt av websidene tilgjengelig fra popcorntime-online.tv 2017-12-18 + og er navngitt «apidomain» i dette dokumentet. Den fjerde ble brukt + av klienten tilgjengelig fra popcorn-time.to i følge dokument 09,12 + på ukjent tidspunkt, og er navngitt «ukrfnlge» i dette + dokumentet. Hvilke kataloger som brukes av ulike Popcorn + Time-klienter endrer seg over tid, da Popcorn Time-klientene i + praksis er nettlesere som viser frem ulike nettsider og disse + nettsidene bytter datakilder når nettsidens eier ønsker det.
+ +Metoden som Ãkokrim legger til grunn, skriver i sitt punkt fire at + skjønn er en egnet metode for Ã¥ finne ut om en film kan lovlig deles + pÃ¥ Internett eller ikke, og sier at det ble «vurdert hvorvidt det + var rimelig Ã¥ forvente om at verket var vernet av copyright». For + det første er det ikke nok Ã¥ slÃ¥ fast om en film er «vernet av + copyright» for Ã¥ vite om det er lovlig Ã¥ dele den pÃ¥ Internett eller + ikke, da det finnes flere filmer med opphavsrettslige bruksvilkÃ¥r + som tillater deling pÃ¥ Internett. Eksempler pÃ¥ dette er Creative + Commons-lisensierte filmer som Citizenfour fra 2014 og Sintel fra + 2010. I tillegg til slike finnes det flere filmer som nÃ¥ er + allemannseie (public domain) pÃ¥ grunn av manglende registrering + eller fornying av registrering selv om bÃ¥de regisør, + produksjonsselskap og distributør ønsker seg vern. Eksempler pÃ¥ + 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 pÃ¥ det tidspunktet, ikke ble gitt tilbakevirkende + kraft. Historien + om sangen «Happy birthday», der betaling for bruk har vært krevd + inn i flere tiÃ¥r selv om sangen ikke var vernet av Ã¥ndsverksloven, + forteller oss at hvert enkelt verk mÃ¥ vurderes nøye og i detalj før + en kan slÃ¥ fast om verket er allemannseie eller ikke, det holder + ikke Ã¥ tro pÃ¥ selverklærte rettighetshavere. Flere eksempel pÃ¥ verk + i det fri som feilklassifiseres som vernet er fra dokument 09,18, + som lister opp søkeresultater for pklienten omtalt som + popcorntime.sh og i følge notatet kun inneholder en film (The Circus + fra 1928) som under tvil kan antas Ã¥ være allemannseie.
+ +Ved rask gjennomlesning av dokument 09,18, som inneholder + skjermbilder fra bruk av en Popcorn Time-variant, fant jeg omtalt + bÃ¥de filmen «The Brain That Wouldn't Die» fra 1962 som + er tilgjengelig + fra Internett-arkivet og + som i + følge Wikipedia er allemannseie i USA da den ble gitt ut i 1962 + uten «copyright»-merking, og filmen «Godâs Little Acre» fra + 1958 som + er lagt ut pÃ¥ Wikipedia, der det fortelles at sort/hvit-utgaven + er allemannseie. Det fremgÃ¥r ikke fra dokument 09,18 om filmen + omtalt der er sort/hvit-utgaven. Av kapasitetsÃ¥rsaker og pÃ¥ grunn av + at filmoversikten i dokument 09,18 ikke er maskinlesbart har jeg + ikke forsøkt Ã¥ sjekke alle filmene som listes opp der om mot liste + med filmer som er antatt lovlig kan distribueres pÃ¥ Internet.
+ +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 ikke hvor mange + filmer i listen som er lovlig å dele på Internet, men at metodens + punkt med vurdering av «rimelig å forvente om at verket var vernet + av copyright» gjør metoden upålitelig.
+ +Den omtalte målemetoden velger ut tilfeldige søketermer fra + ordlisten Dale-Chall. Den ordlisten inneholder 3000 enkle engelske + ord 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.
+ +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.
+ +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 flere + av katalogene 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.

My current home stereo is a patchwork of various pieces I got on -flee markeds over the years. It is amazing what kind of equipment -show up there. I've been wondering for a while if it was possible to -measure how well this equipment is working together, and decided to -see how far I could get using free software. After trawling the web I -came across an article from DIY Audio and Video on -Speaker -Testing and Analysis describing how to test speakers, and it listing -several software options, among them -AUDio MEasurement -System (AUDMES). It is the only free software system I could find -focusing on measuring speakers and audio frequency response. In the -process I also found an interesting article from NOVO on -Understanding -Speaker Specifications and Frequency Response and an article from -ecoustics on -Understanding -Speaker Frequency Response, with a lot of information on what to -look for and how to interpret the graphs. Armed with this knowledge, -I set out to measure the state of my speakers.
+Det er viktig Ã¥ merke seg at de omtalte bittorrent-katalogene ikke + er laget for bruk med Popcorn Time, men for ulike miljøer av + bittorrent-brukere. 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. MÃ¥lemetoden foreslÃ¥tt av Ãkokrim mÃ¥ler dermed ikke + (u)lovligheten rundt bruken av Popcorn Time, men (u)lovligheten til + innholdet i disse katalogene.
-The first hurdle was that AUDMES hadn't seen a commit for 10 years -and did not build with current compilers and libraries. I got in -touch with its author, who no longer was spending time on the program -but gave me write access to the subversion repository on Sourceforge. -The end result is that now the code build on Linux and is capable of -saving and loading the collected frequency response data in CSV -format. The application is quite nice and flexible, and I was able to -select the input and output audio interfaces independently. This made -it possible to use a USB mixer as the input source, while sending -output via my laptop headphone connection. I lacked the hardware and -cabling to figure out a different way to get independent cabling to -speakers and microphone.
+-
Using this setup I could see how a large range of high frequencies -apparently were not making it out of my speakers. The picture show -the frequency response measurement of one of the speakers. Note the -frequency lines seem to be slightly misaligned, compared to the CSV -output from the program. I can not hear several of these are high -frequencies, according to measurement from -Free Hearing Test -Software, an freeware system to measure your hearing (still -looking for a free software alternative), so I do not know if they are -coming out out the speakers. I thus do not quite know how to figure -out if the missing frequencies is a problem with the microphone, the -amplifier or the speakers, but I managed to rule out the audio card in my -PC by measuring my Bose noise canceling headset using its own -microphone. This setup was able to see the high frequency tones, so -the problem with my stereo had to be in the amplifier or speakers.
+Metoden fra Ãkokrims dokument 09,13 i straffesaken + om DNS-beslag.
-Anyway, to try to role out one factor I ended up picking up a new -set of speakers at a flee marked, and these work a lot better than the -old speakers, so I guess the microphone and amplifier is OK. If you -need to measure your own speakers, check out AUDMES. If more people -get involved, perhaps the project could become good enough to include -in Debian? And if you know of some other free software to measure -speakers and amplifier performance, please let me know. I am aware of -the freeware option REW, -but I want something that can be developed also when the vendor -looses interest.

+1. Evaluation of (il)legality
+ +1.1. Methodology + +
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:
+ ++ +
+ +- 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.
+ +- 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).
+ +- 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.
+ +- 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.
+ +1.2. Results
+ +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.
+ +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.
+ +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.
+ +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.
+ +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.

Bittorrent is as far as I know, currently the most efficient way to -distribute content on the Internet. It is used all by all sorts of -content providers, from national TV stations like -NRK, Linux distributors like -Debian and -Ubuntu, and of course the -Internet archive. - -
Almost a month ago -a new -package adding Bittorrent support to VLC became available in -Debian testing and unstable. To test it, simply install it like -this:
- --apt install vlc-plugin-bittorrent -- -
Since the plugin was made available for the first time in Debian, -several improvements have been made to it. In version 2.2-4, now -available in both testing and unstable, a desktop file is provided to -teach browsers to start VLC when the user click on torrent files or -magnet links. The last part is thanks to me finally understanding -what the strange x-scheme-handler style MIME types in desktop files -are used for. By adding x-scheme-handler/magnet to the MimeType entry -in the desktop file, at least the browsers Firefox and Chromium will -suggest to start VLC when selecting a magnet URI on a web page. The -end result is that now, with the plugin installed in Buster and Sid, -one can visit any -Internet -Archive page with movies using a web browser and click on the -torrent link to start streaming the movie.
- -Note, there is still some misfeatures in the plugin. One is the -fact that it will hang and -block VLC -from exiting until the torrent streaming starts. Another is the -fact that it -will pick -and play a random file in a multi file torrent. This is not -always the video file you want. Combined with the first it can be a -bit hard to get the video streaming going. But when it work, it seem -to do a good job.
- -For the Debian packaging, I would love to find a good way to test -if the plugin work with VLC using autopkgtest. I tried, but do not -know enough of the inner workings of VLC to get it working. For now -the autopkgtest script is only checking if the .so file was -successfully loaded by VLC. If you have any suggestions, please -submit a patch to the Debian bug tracking system.
+ +The layered video playout server created by Sveriges Television, +CasparCG Server, entered Debian +today. This completes many months of work to get the source ready to +go into Debian. The first upload to the Debian NEW queue happened a +month ago, but the work upstream to prepare it for Debian started more +than two and a half month ago. So far +the +casparcg-server package is only available for amd64, but I hope +this can be improved. The package is in contrib because it depend on +the non-free fdk-aac +library. The Debian package lack support for streaming web pages +because Debian is missing CEF, Chromium Embedded Framework. CEF is +wanted by several packages in Debian. But because the Chromium source +is not available as a build +dependency, it is not yet possible to upload CEF to Debian. I +hope this will change in the future.
+ +The reason I got involved is that +the Norwegian open channel +Frikanalen is starting to use CasparCG for our HD playout, and I +would like to have all the free software tools we use to run the TV +channel available as packages from the Debian project. The last +remaining piece in the puzzle is Open Broadcast Encoder, but it depend +on quite a lot of patched libraries which would have to be included in +Debian first.

+ +A fun way to learn how to program +Python is to follow the +instructions in the book +"Learn to program +with Minecraft", which introduces programming in Python to people +who like to play with Minecraft. The book uses a Python library to +talk to a TCP/IP socket with an API accepting build instructions and +providing information about the current players in a Minecraft world. +The TCP/IP API was first created for the Minecraft implementation for +Raspberry Pi, and has since been ported to some server versions of +Minecraft. The book contain recipes for those using Windows, MacOSX +and Raspian. But a little known fact is that you can follow the same +recipes using the free software construction game +Minetest.
+ +There is a +Minetest module implementing the same API, making it possible to +use the Python programs coded to talk to Minecraft with Minetest too. +I +uploaded +this module to Debian two weeks ago, and as soon as it clears the +FTP masters NEW queue, learning to program Python with Minetest on +Debian will be a simple 'apt install' away. The Debian package is +maintained as part of the Debian Games team, and +the +packaging rules are currently located under 'unfinished' on +Salsa.
+ +You will most likely need to install several of the Minetest +modules in Debian for the examples included with the library to work +well, as there are several blocks used by the example scripts that are +provided via modules in Minetest. Without the required blocks, a +simple stone block is used instead. My initial testing with a analog +clock did not get gold arms as instructed in the python library, but +instead used stone arms.
+ +I tried to find a way to add the API to the desktop version of +Minecraft, but were unable to find any working recipes. The +recipes +I found are only +working with a standalone Minecraft server setup. Are there any +options to use with the normal desktop version?

Det er altsÃ¥ en menneskerett Ã¥ kunne bevege seg fritt i landet. +For Ã¥ bevege seg fritt i landet, sÃ¥ mÃ¥ en kunne bevege seg uten Ã¥ bli +sporet.

Rettigheter som +ikke blir brukt, blir fjernet.

It would come as no surprise to anyone that I am interested in -bitcoins and virtual currencies. I've been keeping an eye on virtual -currencies for many years, and it is part of the reason a few months -ago, I started writing a python library for collecting currency -exchange rates and trade on virtual currency exchanges. I decided to -name the end result valutakrambod, which perhaps can be translated to -small currency shop.
- -The library uses the tornado python library to handle HTTP and -websocket connections, and provide a asynchronous system for -connecting to and tracking several services. The code is available -from -github.
- -There are two example clients of the library. One is very simple and -list every updated buy/sell price received from the various services. -This code is started by running bin/btc-rates and call the client code -in valutakrambod/client.py. The simple client look like this: - -- --import functools -import tornado.ioloop -import valutakrambod -class SimpleClient(object): - def __init__(self): - self.services = [] - self.streams = [] - pass - def newdata(self, service, pair, changed): - print("%-15s %s-%s: %8.3f %8.3f" % ( - service.servicename(), - pair[0], - pair[1], - service.rates[pair]['ask'], - service.rates[pair]['bid']) - ) - async def refresh(self, service): - await service.fetchRates(service.wantedpairs) - def run(self): - self.ioloop = tornado.ioloop.IOLoop.current() - self.services = valutakrambod.service.knownServices() - for e in self.services: - service = e() - service.subscribe(self.newdata) - stream = service.websocket() - if stream: - self.streams.append(stream) - else: - # Fetch information from non-streaming services immediately - self.ioloop.call_later(len(self.services), - functools.partial(self.refresh, service)) - # as well as regularly - service.periodicUpdate(60) - for stream in self.streams: - stream.connect() - try: - self.ioloop.start() - except KeyboardInterrupt: - print("Interrupted by keyboard, closing all connections.") - pass - for stream in self.streams: - stream.close() -
The library client loops over all known "public" services, -initialises it, subscribes to any updates from the service, checks and -activates websocket streaming if the service provide it, and if no -streaming is supported, fetches information from the service and sets -up a periodic update every 60 seconds. The output from this client -can look like this:
- -- --Bl3p BTC-EUR: 5687.110 5653.690 -Bl3p BTC-EUR: 5687.110 5653.690 -Bl3p BTC-EUR: 5687.110 5653.690 -Hitbtc BTC-USD: 6594.560 6593.690 -Hitbtc BTC-USD: 6594.560 6593.690 -Bl3p BTC-EUR: 5687.110 5653.690 -Hitbtc BTC-USD: 6594.570 6593.690 -Bitstamp EUR-USD: 1.159 1.154 -Hitbtc BTC-USD: 6594.570 6593.690 -Hitbtc BTC-USD: 6594.580 6593.690 -Hitbtc BTC-USD: 6594.580 6593.690 -Hitbtc BTC-USD: 6594.580 6593.690 -Bl3p BTC-EUR: 5687.110 5653.690 -Paymium BTC-EUR: 5680.000 5620.240 -
The exchange order book is tracked in addition to the best buy/sell -price, for those that need to know the details.
- -The other example client is focusing on providing a curses view -with updated buy/sell prices as soon as they are received from the -services. This code is located in bin/btc-rates-curses and activated -by using the '-c' argument. Without the argument the "curses" output -is printed without using curses, which is useful for debugging. The -curses view look like this:

It is the only free software system I could find +focusing on measuring speakers and audio frequency response. In the +process I also found an interesting article from NOVO on +Understanding +Speaker Specifications and Frequency Response and an article from +ecoustics on +Understanding +Speaker Frequency Response, with a lot of information on what to +look for and how to interpret the graphs. Armed with this knowledge, +I set out to measure the state of my speakers.
+ +The first hurdle was that AUDMES hadn't seen a commit for 10 years +and did not build with current compilers and libraries. I got in +touch with its author, who no longer was spending time on the program +but gave me write access to the subversion repository on Sourceforge. +The end result is that now the code build on Linux and is capable of +saving and loading the collected frequency response data in CSV +format. The application is quite nice and flexible, and I was able to +select the input and output audio interfaces independently. This made +it possible to use a USB mixer as the input source, while sending +output via my laptop headphone connection. I lacked the hardware and +cabling to figure out a different way to get independent cabling to +speakers and microphone.
+ +Using this setup I could see how a large range of high frequencies +apparently were not making it out of my speakers. The picture show +the frequency response measurement of one of the speakers. Note the +frequency lines seem to be slightly misaligned, compared to the CSV +output from the program. I can not hear several of these are high +frequencies, according to measurement from +Free Hearing Test +Software, an freeware system to measure your hearing (still +looking for a free software alternative), so I do not know if they are +coming out out the speakers. I thus do not quite know how to figure +out if the missing frequencies is a problem with the microphone, the +amplifier or the speakers, but I managed to rule out the audio card in my +PC by measuring my Bose noise canceling headset using its own +microphone. This setup was able to see the high frequency tones, so +the problem with my stereo had to be in the amplifier or speakers.
+ +Anyway, to try to role out one factor I ended up picking up a new +set of speakers at a flee marked, and these work a lot better than the +old speakers, so I guess the microphone and amplifier is OK. If you +need to measure your own speakers, check out AUDMES. If more people +get involved, perhaps the project could become good enough to +include in Debian? And if +you know of some other free software to measure speakers and amplifier +performance, please let me know. I am aware of the freeware option +REW, but I want something +that can be developed also when the vendor looses interest.

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 -Gadgetbridge. -It provide cloudless collection and storing of data from a variety of -trackers. Its -list -of supported devices 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 -Amazfit -Bip and -Xiaomi -Band 3.
- -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 -Garmin -FIT files containing the collected measurements. While -proprietary, FIT files apparently can be read at least by -GPSBabel and the -GpxPod 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 -Garmin Forerunner -935, 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.
- -A final idea was to build ones own unit, perhaps by basing it on a -wearable hardware platforms like -the Flora Geo -Watch. 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.
- -While I was working on tracking down links, I came across an -inspiring TED talk by Dave Debronkart about -being a -e-patient, and discovered the web site -Participatory -Medicine. 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.
+ +Bittorrent is as far as I know, currently the most efficient way to +distribute content on the Internet. It is used all by all sorts of +content providers, from national TV stations like +NRK, Linux distributors like +Debian and +Ubuntu, and of course the +Internet archive. + +
Almost a month ago +a new +package adding Bittorrent support to VLC became available in +Debian testing and unstable. To test it, simply install it like +this:
+ ++apt install vlc-plugin-bittorrent ++ +
Since the plugin was made available for the first time in Debian, +several improvements have been made to it. In version 2.2-4, now +available in both testing and unstable, a desktop file is provided to +teach browsers to start VLC when the user click on torrent files or +magnet links. The last part is thanks to me finally understanding +what the strange x-scheme-handler style MIME types in desktop files +are used for. By adding x-scheme-handler/magnet to the MimeType entry +in the desktop file, at least the browsers Firefox and Chromium will +suggest to start VLC when selecting a magnet URI on a web page. The +end result is that now, with the plugin installed in Buster and Sid, +one can visit any +Internet +Archive page with movies using a web browser and click on the +torrent link to start streaming the movie.
+ +Note, there is still some misfeatures in the plugin. One is the +fact that it will hang and +block VLC +from exiting until the torrent streaming starts. Another is the +fact that it +will pick +and play a random file in a multi file torrent. This is not +always the video file you want. Combined with the first it can be a +bit hard to get the video streaming going. But when it work, it seem +to do a good job.
+ +For the Debian packaging, I would love to find a good way to test +if the plugin work with VLC using autopkgtest. I tried, but do not +know enough of the inner workings of VLC to get it working. For now +the autopkgtest script is only checking if the .so file was +successfully loaded by VLC. If you have any suggestions, please +submit a patch to the Debian bug tracking system.
