Hvem fører Mediatilsynet tilsyn med?
-
28th June 2015
-

I en global verden med eierskap på tvers, trengs det informasjon om -hvem som har kontrollen i selskaper og bedrifter. Og for å få tilgang -til slik informasjon for alle som ønsker å analysere eierskap, holder -med ikke med nasjonale databaser over eierskap, det må globale -samledatabaser med åpne data til. Heldigvis finnes det en -internasjonal bevegelse for å gjøre selskapsinformasjon for alle land -offentlig tilgjengelig. En slik database heter -OpenCorporates, der -informasjonen er gratis tilgjengelig med en "del på samme -vilkår"-lisens. De samler inn selskapsinformasjon, eierskap, -konsesjonstildelinger og lignende. De manglet ganske mye for Norge, -da bruksvilkårene til Norsk offentlig informasjon i stor grad -blokkerer OpenCorporates fra å samle den inn.

- -

Men jeg er jo involvert i -Frikanalen, som har -TV-konsesjon, og tenkte det kunne være fint om informasjon om alle -mediakonsesjoner var tilgjengelig i OpenCorporates, så jeg sendte -avgårde følgende spørsmål til Mediatilsynet 2015-06-22:

- -
-

Hei. Finnes det en oversikt over enhetene som Mediatilsynet fører -tilsyn med som åpne data? Jeg lette etter den på -<URL:http://data.norge.no/> og -<URL:http://hotell.difi.no/> uten å -finne noe der, og fant heller ikke noe under -<URL:http://www.medietilsynet.no/>.

- -

Jeg tenker på alle som har fått kringkastingskonsesjon og alle som -er omtalt under -<URL:http://www.medietilsynet.no/mediebildet/>.

- -

Jeg skulle gjerne hatt dette maskinlesbart, og inkludert -organisasjonsnummer og hva slags forhold mediatilsynet har til -organisasjonene. Tanken er å importere det i -<URL:https://opencorporates.com/> for analyse, så det bør ikke ha -bruksbegresninger som gjør dette umulig.

-
- -

To dager senere fikk jeg svar, med de datasettene de hadde -tilgjengelig. Svaret fra Hanne Sekkelsten hos Medietilsynet var -informativt og imøtekommende.

- -
-

Vi viser til din e-post av 22. juni, der du ber om å få tilsendt oversikter -over aktører Medietilsynet fører tilsyn med.

- -

Medietilsynet fører tilsyn med kringkastere og audiovisuelle -bestillingstjenester som omfattes av kringkastingsloven, og med -eierskap i aviser, fjernsyn radio og elektroniske medier etter -medieeierskapsloven. I tillegg vil Medietilsynet etter at -beskyttelsesloven trer i kraft fra 1. juli ha tilsyn med en rekke nye -aktører. Nærmere informasjon om den nye loven finnes på Medietilsynets -nettsted, her: -http://www.medietilsynet.no/mediebransjen/bildeprogramloven/ -. Vi har ikke utarbeidet oversikter over alle aktørene, men vi sender -deg her de listene vi har utarbeidet, hentet fra våre databaser. Vi -har dessverre ikke ferdige rapporter som inneholder -organisasjonsnummer. Dersom du ønsker flere opplysninger ber vi om at -du tar kontakt med oss slik at vi kan finne ut av hvilke opplysninger -du trenger, og hvilke vi kan fremskaffe.

Desverre er formatene litt ustrukturerte og mangler endel -informasjon, men det er gode oversikter over hvem Medietilsynet fører -tilsyn med. Filene er på formatene PDF, XPS (XML-basert PDF-lignende -format fra Microsoft) og DOCX, så det vil være en liten jobb å -strukturere informasjonen på en måte som kan importeres i -OpenCorporates. Svaret er ikke i tråd med -Forskrift -om IT-standarder i offentlig forvaltning som sier epostvedlegg -skal sendes som PDF, så jeg har gjorde PDF-utgaver av XPS og -DOCX-utgavene tilgjengelig for å gjøre det enklere for alle å se -innholdet.

Vitenskapen tar som vanlig feil igjen - relativt feil
+
1st August 2016
+

For mange år siden leste jeg en klassisk tekst som gjorde såpass +inntrykk på meg at jeg husker den fortsatt, flere år senere, og bruker +argumentene fra den stadig vekk. Teksten var «The Relativity of +Wrong» som Isaac Asimov publiserte i Skeptical Inquirer i 1989. Den +gir litt perspektiv rundt formidlingen av vitenskapelige resultater. +Jeg har hatt lyst til å kunne dele den også med folk som ikke +behersker Engelsk så godt, som barn og noen av mine eldre slektninger, +og har savnet å ha den tilgjengelig på norsk. For to uker siden tok +jeg meg sammen og kontaktet Asbjørn Dyrendal i foreningen Skepsis om +de var interessert i å publisere en norsk utgave på bloggen sin, og da +han var positiv tok jeg kontakt med Skeptical Inquirer og spurte om +det var greit for dem. I løpet av noen dager fikk vi tilbakemelding +fra Barry Karr hos The Skeptical Inquirer som hadde sjekket og fått OK +fra Robyn Asimov som representerte arvingene i Asmiov-familien og gikk +igang med oversettingen.

+ +

Resultatet, «Relativt +feil» ble publisert på skepsis-bloggen for noen minutter siden. +Jeg anbefaler deg på det varmeste å lese denne teksten og dele den med +dine venner.

+ +

For å håndtere oversettelsen og sikre at original og oversettelse +var i sync brukte vi git, po4a, GNU make og Transifex. Det hele +fungerte utmerket og gjorde det enkelt å dele tekstene og jobbe sammen +om finpuss på formuleringene. Hadde hosted.weblate.org latt meg +opprette nye prosjekter selv i stedet for å måtte kontakte +administratoren der, så hadde jeg brukt weblate i stedet.

Graphing the Norwegian company ownership structure
-
15th June 2015
-

It is a bit work to figure out the ownership structure of companies -in Norway. The information is publicly available, but one need to -recursively look up ownership for all owners to figure out the complete -ownership graph of a given set of companies. To save me the work in -the future, I wrote a script to do this automatically, outputting the -ownership structure using the Graphviz/dotty format. The data source -is web scraping from Proff, because -I failed to find a useful source directly from the official keepers of -the ownership data, Brønnøysundsregistrene.

- -

To get an ownership graph for a set of companies, fetch -the code from git and run it using the organisation number. I'm -using the Norwegian newspaper Dagbladet as an example here, as its -ownership structure is very simple:

- -
-% time ./bin/eierskap-dotty 958033540 > dagbladet.dot
-
-real    0m2.841s
-user    0m0.184s
-sys     0m0.036s
-%
-
- -

The script accept several organisation numbers on the command line, -allowing a cluster of companies to be graphed in the same image. The -resulting dot file for the example above look like this. The edges -are labeled with the ownership percentage, and the nodes uses the -organisation number as their name and the name as the label:

- -
-digraph ownership {
-rankdir = LR;
-"Aller Holding A/s" -> "910119877" [label="100%"]
-"910119877" -> "998689015" [label="100%"]
-"998689015" -> "958033540" [label="99%"]
-"974530600" -> "958033540" [label="1%"]
-"958033540" [label="AS DAGBLADET"]
-"998689015" [label="Berner Media Holding AS"]
-"974530600" [label="Dagbladets Stiftelse"]
-"910119877" [label="Aller Media AS"]
-}
-
- -

To view the ownership graph, run "dotty dagbladet.dot" or -convert it to a PNG using "dot -T png dagbladet.dot > -dagbladet.png". The result can be seen below:

- - - -

Note that I suspect the "Aller Holding A/S" entry to be incorrect -data in the official ownership register, as that name is not -registered in the official company register for Norway. The ownership -register is sensitive to typos and there seem to be no strict checking -of the ownership links.

- -

Let me know if you improve the script or find better data sources. -The code is licensed according to GPL 2 or newer.

- -

Update 2015-06-15: Since the initial post I've been told that -"Aller -Holding A/S" is a Danish company, which explain why it did not -have a Norwegian organisation number. I've also been told that there -is a web -services API available from Brønnøysundsregistrene, for those -willing to accept the terms or pay the price.

Techno TV broadcasting live across Norway and the Internet (#debconf16, #nuug) on @frikanalen
+
1st August 2016
+

Did you know there is a TV channel broadcasting talks from DebConf +16 across an entire country? Or that there is a TV channel +broadcasting talks by or about +Linus Torvalds, +Tor, +OpenID, +Common Lisp, +Civic Tech, +EFF founder John Barlow, +how to make 3D +printer electronics and many more fascinating topics? It works +using only free software (all of it +available from Github), and +is administrated using a web browser and a web API.

+ +

The TV channel is the Norwegian open channel +Frikanalen, and I am involved +via the NUUG member association in +running and developing the software for the channel. The channel is +organised as a member organisation where its members can upload and +broadcast what they want (think of it as Youtube for national +broadcasting television). Individuals can broadcast too. The time +slots are handled on a first come, first serve basis. Because the +channel have almost no viewers and very few active members, we can +experiment with TV technology without too much flack when we make +mistakes. And thanks to the few active members, most of the slots on +the schedule are free. I see this as an opportunity to spread +knowledge about technology and free software, and have a script I run +regularly to fill up all the open slots the next few days with +technology related video. The end result is a channel I like to +describe as Techno TV - filled with interesting talks and +presentations.

+ +

It is available on channel 50 on the Norwegian national digital TV +network (RiksTV). It is also available as a multicast stream on +Uninett. And finally, it is available as +a WebM unicast stream from +Frikanalen and NUUG. Check it out. :)

Measuring and adjusting the loudness of a TV channel using bs1770gain
-
11th June 2015
-

Television loudness is the source of frustration for viewers -everywhere. Some channels are very load, others are less loud, and -ads tend to shout very high to get the attention of the viewers, and -the viewers do not like this. This fact is well known to the TV -channels. See for example the BBC white paper -"Terminology -for loudness and level dBTP, LU, and all that" from 2011 for a -summary of the problem domain. To better address the need for even -loadness, the TV channels got together several years ago to agree on a -new way to measure loudness in digital files as one step in -standardizing loudness. From this came the ITU-R standard BS.1770, -"Algorithms to -measure audio programme loudness and true-peak audio level".

- -

The ITU-R BS.1770 specification describe an algorithm to measure -loadness in LUFS (Loudness Units, referenced to Full Scale). But -having a way to measure is not enough. To get the same loudness -across TV channels, one also need to decide which value to standardize -on. For European TV channels, this was done in the EBU Recommondaton -R128, "Loudness -normalisation and permitted maximum level of audio signals", which -specifies a recommended level of -23 LUFS. In Norway, I have been -told that NRK, TV2, MTG and SBS have decided among themselves to -follow the R128 recommondation for playout from 2016-03-01.

- -

There are free software available to measure and adjust the loudness -level using the LUFS. In Debian, I am aware of a library named -libebur128 -able to measure the loudness and since yesterday morning a new binary -named bs1770gain -capable of both measuring and adjusting was uploaded and is waiting -for NEW processing. I plan to maintain the latter in Debian under the -Debian -multimedia umbrella.

- -

The free software based TV channel I am involved in, -Frikanalen, plan to follow the -R128 recommondation ourself as soon as we can adjust the software to -do so, and the bs1770gain tool seem like a good fit for that part of -the puzzle to measure loudness on new video uploaded to Frikanalen. -Personally, I plan to use bs1770gain to adjust the loudness of videos -I upload to Frikanalen on behalf of the -NUUG member organisation. The program seem to be able to measure -the LUFS value of any media file handled by ffmpeg, but I've only -successfully adjusted the LUFS value of WAV files. I suspect it -should be able to adjust it for all the formats handled by ffmpeg.

Unlocking HTC Desire HD on Linux using unruu and fastboot
+
7th July 2016
+

Yesterday, I tried to unlock a HTC Desire HD phone, and it proved +to be a slight challenge. Here is the recipe if I ever need to do it +again. It all started by me wanting to try the recipe to set up +an +hardened Android installation from the Tor project blog on a +device I had access to. It is a old mobile phone with a broken +microphone The initial idea had been to just +install +CyanogenMod on it, but did not quite find time to start on it +until a few days ago.

+ +

The unlock process is supposed to be simple: (1) Boot into the boot +loader (press volume down and power at the same time), (2) select +'fastboot' before (3) connecting the device via USB to a Linux +machine, (4) request the device identifier token by running 'fastboot +oem get_identifier_token', (5) request the device unlocking key using +the HTC developer web +site and unlock the phone using the key file emailed to you.

+ +

Unfortunately, this only work fi you have hboot version 2.00.0029 +or newer, and the device I was working on had 2.00.0027. This +apparently can be easily fixed by downloading a Windows program and +running it on your Windows machine, if you accept the terms Microsoft +require you to accept to use Windows - which I do not. So I had to +come up with a different approach. I got a lot of help from AndyCap +on #nuug, and would not have been able to get this working without +him.

+ +

First I needed to extract the hboot firmware from +the +windows binary for HTC Desire HD downloaded as 'the RUU' from HTC. +For this there is is a github +project named unruu using libunshield. The unshield tool did not +recognise the file format, but unruu worked and extracted rom.zip, +containing the new hboot firmware and a text file describing which +devices it would work for.

+ +

Next, I needed to get the new firmware into the device. For this I +followed some instructions +available +from HTC1Guru.com, and ran these commands as root on a Linux +machine with Debian testing:

+ +

+adb reboot-bootloader
+fastboot oem rebootRUU
+fastboot flash zip rom.zip
+fastboot flash zip rom.zip
+fastboot reboot
+

+ +

The flash command apparently need to be done twice to take effect, +as the first is just preparations and the second one do the flashing. +The adb command is just to get to the boot loader menu, so turning the +device on while holding volume down and the power button should work +too.

+ +

With the new hboot version in place I could start following the +instructions on the HTC developer web site. I got the device token +like this:

+ +

+fastboot oem get_identifier_token 2>&1 | sed 's/(bootloader) //'
+
+ +

And once I got the unlock code via email, I could use it like +this:

+ +

+fastboot flash unlocktoken Unlock_code.bin
+

+ +

And with that final step in place, the phone was unlocked and I +could start stuffing the software of my own choosing into the device. +So far I only inserted a replacement recovery image to wipe the phone +before I start. We will see what happen next. Perhaps I should +install Debian on it. :)

Hva gjør at NRK kan distribuere H.264-video uten patentavtale med MPEG LA?
-
10th June 2015
-

Helt siden jeg i 2012 fikk beskjed fra MPEG LA om at -NRK -trengte patentavtale med dem hvis de distribuerte H.264-video til -sluttbrukere, har jeg lurt på hva som gjør at NRK ikke har slik -avtale. For noen dager siden fikk jeg endelig gjort noe med min -undring, og sendte 2015-05-28 følgende epost til info (at) nrk.no med -tittel "Hva gjør at NRK kan distribuere H.264-video uten patentavtale -med MPEG LA?":

- -

-

Jeg lurer på en ting rundt NRKs bruk av H.264-video på sine -websider samt distribusjon via RiksTV og kabel-TV. Har NRK vurdert om -det er behov for en patentavtale med -MPEG LA slik det står i -programvarelisensene til blant annet Apple Final Cut Studio, Adobe -Premiere Pro, Avid og Apples Final Cut Pro X?

- -

Hvis dere har vurdert dette, hva var utfallet av en slik vurdering?

- -

Hvis dere ikke har vurdert dette, har NRK planer om å vurdere behovet -for patentavtale?

- -

I følge en artikkel på -NRK -Beta i 2012 har NRK brukt eller testet både Apple Final Cut -Studio, Adobe Premiere Pro, Avid og Apples Final Cut Pro X til bruk -for å redigere video før sending. Alle disse har bruksvilkår -understøttet av opphavsretten som sier at de kun kan brukes til å lage -filmer til personlig og ikke-kommersiell bruk - med mindre en har en -lisensavtale med MPEG LA om bruk av patenter utstedt i USA for H.264. -Se f.eks. bruksvilkårene for Avid, Adobe Premiere og Apple Final -Cut Studio og søk etter "MPEG LA".

- -

Dette får meg til å lure på om det er brudd på opphavsretten å bruke -disse verktøyene i strid med bruksvilkårene uten patentavtale med MPEG -LA. Men NRK bruker jo tilsynelatende disse verktøyene uten patentavtale -med MPEG LA.

- -

I følge forfatteren av Open Broadcast Encoder finnes det to typer -H.264-relaterte avtaler en kan få med MPEG LA. Det er én for å lage -programvare og utstyr som produserer H.264-video, og en annen for å -kringkaste video som bruker H.264. Dette forteller meg at selv om -produsentene av utstyr og programvare som NRK bruker har en slik avtale -med MPEG LA, så trenges det en egen avtale for å kringkaste video på det -formatet.

- -

I følge Ryan Rodriguez hos MPEG LA, da jeg spurte ham på epost i -juni 2012, har NRK ikke en slik avtale med MPEG LA. Han sa videre at -NRK trenger en slik avtale hvis NRK tilbyr H.264-kodet video til -sluttbrukere. Jeg sjekket listen med -organisasjoner -med avtale med MPEG LA og NRK står fortsatt ikke der.

- -

Jeg lurer dermed på hva som gjør at NRK kan bruke de overnevnte -videoredigeringsverktøyene, som tilsynelatende har krav om avtale med -MPEG LA for å kunne brukes slik NRK bruker dem, til å lage videofiler -for distribusjon uten å ha en avtale med MPEG LA om distribusjon av -H.264-video? Dette er spesielt interessant å vite for oss andre som -også vurderer å spre H.264-video etter å ha redigert dem med disse mye -brukte videoredigeringsverktøyene.

-

- -

Samme dag fikk jeg automatisk svar om at min henvendelse hadde fått -saksid 1294699. Jeg fikk deretter følgende respons fra NRK -2015-06-09:

- -

-

Hei, beklager lang svartid, men det tok litt tid å finne ut hvem som kunne -svare på dette.

- -

For selskaper som leverer h.264 til sluttbrukere på nett (f.eks -NRKs nett- tv utgaver som bruker h.264) - og som leverer slike -tjenester uten betaling fra forbrukere – er det heller ikke påkrevd -noen patentavtale.

- -

Spørsmålet er ikke kun om MPEG LA krever patentavtale eller ikke -(hvilket ikke helt besvares av pressemeldingen omtalt over, gitt at -pressemeldingen kom i 2010, to år før MPEG LA ansvarlige for -internasjonal lisensiering egen Ryan Rodriguez fortalte meg på epost -at NRK trenger en lisens.

- -

Det er uklart fra pressemeldingen hva "Internet Broadcast AVC -Video" konkret betyr, men i følge en -presentasjon -fra MPEG LA med tema "AVC PAtent Portfoli License Briefing" datert -2015-05-15 gjelder "Internet Broadcast AVC Video" kun kringkasting -på Internet som ikke tilbyr valg av enkeltinnslag ("not -title-by-title"), hvilket jo NRK gjør på sine nettsider. I tillegg -kringkaster jo NRK H.264-video også utenom Internet (RiksTV, kabel, -satelitt), hvilket helt klart ikke er dekket av vilkårene omtalt i -pressemeldingen.

- -

Spørsmålet mitt er hvordan NRK kan bruke verktøy med bruksvilkår -som krever avtale med MPEG LA for det NRK bruker dem til, når NRK ikke -har avtale med MPEG LA. Hvis jeg forsto spørsmålet riktig, så mener -NRK at dere ikke trenger avtale med MPEG LA, men uten slik avtale kan -dere vel ikke bruke hverken Apple Final Cut Studio, Adobe Premiere -Pro, Avid eller Apples Final Cut Pro X for å redigere video før -sending?

How to use the Signal app if you only have a land line (ie no mobile phone)

3rd July 2016

For a while now, I have wanted to test +the Signal app, as it is +said to provide end to end encrypted communication and several of my +friends and family are already using it. As I by choice do not own a +mobile phone, this proved to be harder than expected. And I wanted to +have the source of the client and know that it was the code used on my +machine. But yesterday I managed to get it working. I used the +Github source, compared it to the source in +the +Signal Chrome app available from the Chrome web store, applied +patches to use the production Signal servers, started the app and +asked for the hidden "register without a smart phone" form. Here is +the recipe how I did it.

+ +

First, I fetched the Signal desktop source from Github, using -

    +
    +git clone https://github.com/WhisperSystems/Signal-Desktop.git
+
    + +

    Next, I patched the source to use the production servers, to be +able to talk to other Signal users:

Det hjelper å ha funnet rette vedkommende i NRK, for denne gangen -fikk jeg svar tilbake dagen etter (2015-06-10), fra Geir Børdalen i -NRK:

Hei Petter Reinholdtsen

- -

Jeg har sjekket saken med distribusjonssjef for tv, Arild Hellgren -(som var teknologidirektør da bakkenettet ble satt opp). NRK v/ -Hellgren hadde møte med MPEG LA sammen med den europeiske -kringkastingsunionen EBU før bakkenettet for TV ble satt opp -(igangsatt høsten 2007). I dette møtet ble det avklart at NRK/EBU ikke -trengte noen patentavtale for h.264 i forbindelse med oppsett av -bakkenettet eller bruk av MPEG4 h.264 som kompresjonsalgoritme fordi -tjenesten «in full»(nor: helt) var betalt av utsendelseselskapene og -ikke av forbrukerne.

- -

http://www.nrk.no/oppdrag/digitalt-bakkenett-1.3214555

- -

Det er også klart slått fast at selskaper som leverer video basert -på MPEG4 h.264 til sluttbrukere på nett, heller ikke påkrevd noen -patentavtale – så lenge de leverer slike tjenester uten betaling fra -sluttbrukere.

- -http://www.businesswire.com/news/home/20100825006629/en/MPEG-LA%E2%80%99s-AVC-License-Charge-Royalties-Internet#.VWb2ws_774Y - -

“MPEG LA announced today that its AVC Patent Portfolio License will -continue not to charge royalties for Internet Video that is free to -end users (known as “Internet Broadcast AVC Video”) during the entire -life of this License. MPEG LA previously announced it would not charge -royalties for such video through December 31, 2015 (see -http://www.mpegla.com/Lists/MPEG%20LA%20News%20List/Attachments/226/n-10-02-02.pdf), -and today’s announcement makes clear that royalties will continue not -to be charged for such video beyond that time. Products and services -other than Internet Broadcast AVC Video continue to be -royalty-bearing.”

- -

Vi har derfor ikke noe behov for å vurdere noen patentavtale med -MPEG LA.

- -

Understreker for øvrig at NRK ikke er låst til MPEG4 – h.264 som -utsendelsesformat – og at vi har brukt og bruker flere andre -alternativer i våre tjenester. Ulike «devicer» har ofte behov for -forskjellige løsninger – og NRK har forsøkt å levere med best mulig -kvalitet /økonomi /stabilitet avhengig av -plattform. Produksjonsformater i NRK spenner for øvrig over en rekke -forskjellige formater – hvor MPEG4 bare er en av disse. Når NRK kjøper -teknisk utstyr er betaling for kodekstøtte ofte en del av -anskaffelsesprisen for denne maskinvaren (enten dette er spesialiserte -enkodere eller forskjellige typer produksjonsutstyr).

> Hei Petter Reinholdtsen

Hei, og takk for raskt svar. Er min henvendelse journalført slik -at den dukker opp i NRKs postjournal?

- -

Svaret ditt var meget nyttig, og jeg forstår ut fra det du skriver -at avklaringen med MPEG LA rundt H.264-distribusjon via bakkenettet -gjelder alle TV-kanaler i Norge. Hvilke saksnummer fikk dokumenter -som ble opprettet i forbindelse med det omtalte møtet NRK v/Hellgren -og EBU hadde med MPEG LA (dvs. referater, avtaler, etc), -f.eks. dokumentet der formuleringen "in full" som du omtaler -finnes?

- -

Men det er et par ting jeg fortsatt ikke forstår. Det ene er -hvorfor NRKs forståelse av hva "Internet Broadcast AVC Video" dekker -ser ut til å avvike fra det som presenteres i -lysark -fra MPEG LA i mai, der MPEG LA på lysark med overskriften -"AVC/H.264 License Terms Participation Fees" og undertittel "Where -remuneration is from other sources" skriver "Internet Broadcast AVC -Video (not title-by-title, not subscription) – no royalty for life of -the AVC Patent Portfolio License".

- -

Her leser jeg MPEG LA dithen at det kun er kringkasting uten -abonnement via Internet som er dekket at vilkårne omtalt i -pressemeldingen, mens jeg forstår deg dithen at NRK mener NRKs -nettsider som også har enkeltfilmer og innslag (som jeg forstår dekket -av formuleringen "title-by-title") dekkes av "Internet Broadcast AVC -Video" fra MPEG LA. Hva baserer dere denne tolkningen på? Jeg har -ikke sett noe skriftlig fra MPEG LA som støtter NRKs tolkning, og -lurer på om dere har andre kilder enn den pressemeldingen fra 5 år -tilbake, der NRKS forståelse av hva "Internet Broadcast AVC Video" -dekker er beskrevet?

- -

Det andre er at eposten din ikke nevnte spørsmålet mitt om -bruksvilkårene til videoredigeringsverktøyene som NRK bruker. Disse -har som tidligere nevnt krav om at de kun skal brukes til private og -ikke-kommersielle formål med mindre en har avtale med MPEG LA, og uten -avtale med MPEG LA kan det jo virke som om NRK bruker verktøyene i -strid med bruksvilkårene. Hva gjør at disse bruksvilkårene ikke -gjelder for NRK?

-

- -

Noen minutter senere får jeg foreløpig siste svar i -føljetongen:

- -

-

Hei igjen

Vårt dokumentarkiv har fått en kopi (journalføringsnr kan jeg -dessverre ikke gi deg).

> Svaret ditt var meget nyttig, og jeg forstår ut fra det du -

- -

Svar: Kan ikke svare for andre enn for NRK/EBU - og for bakkenettet -i Norge er det kun NRK som er et lisensbasert selskap. Kan ikke gi noe -svar på saksnr på dokumenter eller ytterligere informasjon da jeg selv -ikke var del i dette.

- -

> Men det er et par ting jeg fortsatt ikke forstår. ...

- -

Svar: Kan ikke gå ytterligere inn i dette fra min side og mitt -fagfelt som er produksjon/publisering og systemstrukturene bak -disse. For øvrig ligger det etter vår formening ingen begrensninger -for NRK i mulighetene til publisering mht til kodek i -produksjonssystemer. Som tidligere skrevet mener vi at NRK ikke -trenger noen avtale med MPEG LA og støtter oss til det vi allerede har -kommunisert i forrige epost.

Det syntes vanskelig å komme videre når NRK ikke ønsker å gå inn i -problemstillingen rundt bruksvilkårene til videoredigeringsverktøyene -NRK bruker, så jeg sendte takk for svarene og avsluttet utvekslingen -så langt:

- -

-

Tusen takk for rask respons, og oppklarende forklaring om hvordan -NRK tenker rundt MPEG LA.

- -

Jeg vil høre med NRK-arkivet for å se om de kan spore opp de -omtalte dokumentene. Jeg setter pris på om du kan dele titler, dato -eller annen informasjon som kan gjøre det enklere for arkivet å finne -dem.

- -

Når det gjelder hvordan bruksvilkårene til -videoredigeringsverktøyene skal tolkes, så skal jeg høre med MPEG LA -og produsentene av verktøyene for å forsøke å få klarhet i hva de -mener er rikgig rettstilstand.

-

- -

Jeg ble litt klokere, men fortsatt er det uklart for meg hva som er -grunnlaget til NRK for å se bort fra bruksvilkår i -videoredigeringsprogramvare som krever MPEG LA-avtale til alt annet -enn privat og ikke-kommersiell bruk.

The script start the app and configure Chromium to use the Tor +SOCKS5 proxy to make sure those controlling the Signal servers (today +Amazon and Whisper Systems) as well as those listening on the lines +will have a harder time location my laptop based on the Signal +connections if they use source IP address.

When the script starts, one need to follow the instructions under +"Standalone Registration" in the CONTRIBUTING.md file in the git +repository. I right clicked on the Signal window to get up the +Chromium debugging tool, visited the 'Console' tab and wrote +'extension.install("standalone")' on the console prompt to get the +registration form. Then I entered by land line phone number and +pressed 'Call'. 5 seconds later the phone rang and a robot voice +repeated the verification code three times. After entering the number +into the verification code field in the form, I could start using +Signal from my laptop. + +

As far as I can tell, The Signal app will leak who is talking to +whom and thus who know who to those controlling the central server, +but such leakage is hard to avoid with a centrally controlled server +setup. It is something to keep in mind when using Signal - the +content of your chats are harder to intercept, but the meta data +exposing your contact network is available to people you do not know. +So better than many options, but not great. And sadly the usage is +connected to my land line, thus allowing those controlling the server +to associate it to my home and person. I would prefer it if only +those I knew could tell who I was on Signal. There are options +avoiding such information leakage, but most of my friends are not +using them, so I am stuck with Signal for now.

Blir det virkelig krav om fingeravtrykk i nasjonale ID-kort?
-
12th May 2015
-

Noen finner det vanskelig å tro at Stortinget faktisk har vedtatt å -kreve at alle norske borgerne må avgi fingeravtrykk til politiet for å -fungere i samfunnet. Jeg er blitt spurt hva som er grunnlaget for -min -påstand i forrige bloggpost om at det nå blir krav om å avgi -fingeravtrykk til politiet for å fungere som borger i Norge. De som -spør klarer ikke lese det ut fra det som er vedtatt. Her er en liten -oppsummering om hva jeg baserer det på. Det sies ikke direkte i -hverken proposisjon, innstilling eller vedtak, men fremgår når en ser -på indirekte formuleringer.

- -

I -stortingsproposisjon -66, avsnitt 6.3.5 (Avgivelse av biometriske personopplysninger) -står det

- -

- -

Departementet foreslår at både ansiktsfoto og fingeravtrykk skal - kunne opptas og lagres som identifikasjonsdata i de nasjonale - ID-kortene, på samme måte som i passene. Lovforslaget er derfor - utformet i tråd med passloven § 6 annet ledd, som fastslår at det - til bruk for senere verifisering eller kontroll av passinnehaverens - identitet kan innhentes og lagres i passet biometrisk - personinformasjon i form av ansiktsfoto og fingeravtrykk (to - fingre). Dagens ordning med lagring av ansiktsfoto og fingeravtrykk - i et kontaktløst smartkort i passet er basert på internasjonale - standarder. Fingeravtrykkene i nasjonalt ID-kort vil bli beskyttet - på samme måte som fingeravtrykkene i passene.

- -

[...]

- -

For norske forhold understreker departementet at innføring av - nasjonale ID-kort sammen med innføring av nye systemer for sikrere - utstedelse og kontroll av pass og relaterte dokumenter gir mulighet - til å utforme ordningen slik at den best mulig møter utfordringene - forbundet med identitetskriminalitet. Det tilsier at fingeravtrykk - opptas og lagres i alle nasjonale ID-kort.

-

- -

Departementet sier altså at sin anbefaling er at fingeravtrykk skal -opptas og lagres i alle nasjonale ID-kort. Det skrives som om det -blir valgfritt, på samme måten som det skrives passloven, der det i -loven sier at det kan -«innhentes -og lagres i passet biometrisk personinformasjon i form av ansiktsfoto -og fingeravtrykk (to fingre)». Men på tross av bruken av «kan» i -passloven er det innført krav om å avgi fingeravtrykk for å få et pass -i Norge. Proposisjonen sier i tillegg i del 1 (Proposisjonens -hovedinnhold) at ID-kortene skal være like pålitelig som pass og ha -samme sikkerhetsnivå som pass. Departementet foreslår altså at -ID-kortene skal gis etter samme regler som for pass.

- -

Formuleringene fra hovedinnholdet i proposisjonen er videreført i -innstillingen -fra stortingskomiteen, der det konkret står «De foreslåtte reglene -vil gi befolkningen tilbud om et offentlig utstedt identitetsbevis som -vil være like pålitelig som passet, og mer praktisk å bruke som -legitimasjon» og «Det nasjonale ID-kortet skal også holde samme -sikkerhetsnivå som passet». Komiteen har altså ingen kommentarer -eller innsigelser til dette forslaget, og gjorde i debatten da saken -ble vedtatt det klart at dette var en god sak og at en enstemmig -komité var glad for resultatet. Stortinget har dermed stilt seg helt -og fullt bak departementets forslag.

- -

For meg er det åpenbart når en leser proposisjonen at «like -pålitelig» og «samme sikkerhetsnivå» vil bli tolket av departementet -som «med samme biometrisk informasjon som i passene», og departementet -forklarer i tillegg i proposisjonen at de har tenkt at -fingeravtrykkene «vil bli beskyttet på samme måte som fingeravtrykkene -i passene». Jeg ser det dermed som åpenbart at den samme -tvangsinnhentingen av fingeravtrykk som gjelder for pass vil bli -viderført til de nasjonale ID-kortene.

- -

Det eneste som kan endre dette er massive protester fra -befolkningen på at folk som ikke er mistenkt for noe kriminelt skal -tvinges til å gi fingeravtrykket til politiet for å f.eks. kunne få -bankkonto eller stemme ved valg. Det kunne få departementet til å -snu. Det tror jeg ikke vil skje.

The new "best" multimedia player in Debian?
+
6th June 2016
+

When I set out a few weeks ago to figure out +which +multimedia player in Debian claimed to support most file formats / +MIME types, I was a bit surprised how varied the sets of MIME types +the various players claimed support for. The range was from 55 to 130 +MIME types. I suspect most media formats are supported by all +players, but this is not really reflected in the MimeTypes values in +their desktop files. There are probably also some bogus MIME types +listed, but it is hard to identify which one this is.

+ +

Anyway, in the mean time I got in touch with upstream for some of +the players suggesting to add more MIME types to their desktop files, +and decided to spend some time myself improving the situation for my +favorite media player VLC. The fixes for VLC entered Debian unstable +yesterday. The complete list of MIME types can be seen on the +Multimedia +player MIME type support status Debian wiki page.

+ +

The new "best" multimedia player in Debian? It is VLC, followed by +totem, parole, kplayer, gnome-mpv, mpv, smplayer, mplayer-gui and +kmplayer. I am sure some of the other players desktop files support +several of the formats currently listed as working only with vlc, +toten and parole.

+ +

A sad observation is that only 14 MIME types are listed as +supported by all the tested multimedia players in Debian in their +desktop files: audio/mpeg, audio/vnd.rn-realaudio, audio/x-mpegurl, +audio/x-ms-wma, audio/x-scpls, audio/x-wav, video/mp4, video/mpeg, +video/quicktime, video/vnd.rn-realvideo, video/x-matroska, +video/x-ms-asf, video/x-ms-wmv and video/x-msvideo. Personally I find +it sad that video/ogg and video/webm is not supported by all the media +players in Debian. As far as I can tell, all of them can handle both +formats.

Norwegian citizens now required by law to give their fingerprint to the police
-
10th May 2015
-

5 days ago, the Norwegian Parliament decided, unanimously, that all -citizens of Norway, no matter if they are suspected of something -criminal or not, are -required to -give fingerprints to the police (vote details from Holder de -ord). The law make it sound like it will be optional, but in a few -years there will be no option any more. The ID will be required to -vote, to get a bank account, a bank card, to change address on the -post office, to receive an electronic ID or to get a drivers license -and many other tasks required to function in Norway. The banks plan -to stop providing their own ID on the bank cards when this new -national ID is introduced, and the national road authorities plan to -change the drivers license to no longer be usable as identity cards. -In effect, to function as a citizen in Norway a national ID card will -be required, and to get it one need to provide the fingerprints to -the police.

- -

In addition to handing the fingerprint to the police (which -promised to not make a copy of the fingerprint image at that point in -time, but say nothing about doing it later), a picture of the -fingerprint will be stored on the RFID chip, along with a picture of -the face and other information about the person. Some of the -information will be encrypted, but the encryption will be the same -system as currently used in the passports. The codes to decrypt will -be available to a lot of government offices and their suppliers around -the globe, but for those that do not know anyone in those circles it -is good to know that -the -encryption is already broken. And they -can -be read from 70 meters away. This can be mitigated a bit by -keeping it in a Faraday cage (metal box or metal wire container), but -one will be required to take it out of there often enough to expose -ones private and personal information to a lot of people that have no -business getting access to that information.

- -

The new Norwegian national IDs are a vehicle for identity theft, -and I feel sorry for us all having politicians accepting such invasion -of privacy without any objections. So are the Norwegian passports, -but it has been possible to function in Norway without those so far. -That option is going away with the passing of the new law. In this, I -envy the Germans, because for them it is optional how much biometric -information is stored in their national ID.

- -

And if forced collection of fingerprints was not bad enough, the -information collected in the national ID card register can be handed -over to foreign intelligence services and police authorities, "when -extradition is not considered disproportionate".

A program should be able to open its own files on Linux
+
5th June 2016
+

Many years ago, when koffice was fresh and with few users, I +decided to test its presentation tool when making the slides for a +talk I was giving for NUUG on Japhar, a free Java virtual machine. I +wrote the first draft of the slides, saved the result and went to bed +the day before I would give the talk. The next day I took a plane to +the location where the meeting should take place, and on the plane I +started up koffice again to polish the talk a bit, only to discover +that kpresenter refused to load its own data file. I cursed a bit and +started making the slides again from memory, to have something to +present when I arrived. I tested that the saved files could be +loaded, and the day seemed to be rescued. I continued to polish the +slides until I suddenly discovered that the saved file could no longer +be loaded into kpresenter. In the end I had to rewrite the slides +three times, condensing the content until the talk became shorter and +shorter. After the talk I was able to pinpoint the problem – +kpresenter wrote inline images in a way itself could not understand. +Eventually that bug was fixed and kpresenter ended up being a great +program to make slides. The point I'm trying to make is that we +expect a program to be able to load its own data files, and it is +embarrassing to its developers if it can't.

+ +

Did you ever experience a program failing to load its own data +files from the desktop file browser? It is not a uncommon problem. A +while back I discovered that the screencast recorder +gtk-recordmydesktop would save an Ogg Theora video file the KDE file +browser would refuse to open. No video player claimed to understand +such file. I tracked down the cause being file --mime-type +returning the application/ogg MIME type, which no video player I had +installed listed as a MIME type they would understand. I asked for +file to change its +behavour and use the MIME type video/ogg instead. I also asked +several video players to add video/ogg to their desktop files, to give +the file browser an idea what to do about Ogg Theora files. After a +while, the desktop file browsers in Debian started to handle the +output from gtk-recordmydesktop properly.

+ +

But history repeats itself. A few days ago I tested the music +system Rosegarden again, and I discovered that the KDE and xfce file +browsers did not know what to do with the Rosegarden project files +(*.rg). I've reported the +rosegarden problem to BTS and a fix is commited to git and will be +included in the next upload. To increase the chance of me remembering +how to fix the problem next time some program fail to load its files +from the file browser, here are some notes on how to fix it.

+ +

The file browsers in Debian in general operates on MIME types. +There are two sources for the MIME type of a given file. The output from +file --mime-type mentioned above, and the content of the +shared MIME type registry (under /usr/share/mime/). The file MIME +type is mapped to programs supporting the MIME type, and this +information is collected from +the +desktop files available in /usr/share/applications/. If there is +one desktop file claiming support for the MIME type of the file, it is +activated when asking to open a given file. If there are more, one +can normally select which one to use by right-clicking on the file and +selecting the wanted one using 'Open with' or similar. In general +this work well. But it depend on each program picking a good MIME +type (preferably +a +MIME type registered with IANA), file and/or the shared MIME +registry recognizing the file and the desktop file to list the MIME +type in its list of supported MIME types.

+ +

The /usr/share/mime/packages/rosegarden.xml entry for +the +Shared MIME database look like this:

+ +

+<?xml version="1.0" encoding="UTF-8"?>
+<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
+  <mime-type type="audio/x-rosegarden">
+    <sub-class-of type="application/x-gzip"/>
+    <comment>Rosegarden project file</comment>
+    <glob pattern="*.rg"/>
+  </mime-type>
+</mime-info>
+

+ +

This states that audio/x-rosegarden is a kind of application/x-gzip +(it is a gzipped XML file). Note, it is much better to use an +official MIME type registered with IANA than it is to make up ones own +unofficial ones like the x-rosegarden type used by rosegarden.

+ +

The desktop file of the rosegarden program failed to list +audio/x-rosegarden in its list of supported MIME types, causing the +file browsers to have no idea what to do with *.rg files:

+ +

+% grep Mime /usr/share/applications/rosegarden.desktop
+MimeType=audio/x-rosegarden-composition;audio/x-rosegarden-device;audio/x-rosegarden-project;audio/x-rosegarden-template;audio/midi;
+X-KDE-NativeMimeType=audio/x-rosegarden-composition
+%
+

+ +

The fix was to add "audio/x-rosegarden;" at the end of the +MimeType= line.

+ +

If you run into a file which fail to open the correct program when +selected from the file browser, please check out the output from +file --mime-type for the file, ensure the file ending and +MIME type is registered somewhere under /usr/share/mime/ and check +that some desktop file under /usr/share/applications/ is claiming +support for this MIME type. If not, please report a bug to have it +fixed. :)

What would it cost to store all phone calls in Norway?
-
1st May 2015
-

Many years ago, a friend of mine calculated how much it would cost -to store the sound of all phone calls in Norway, and came up with the -cost of around 20 million NOK (2.4 mill EUR) for all the calls in a -year. I got curious and wondered what the same calculation would look -like today. To do so one need an idea of how much data storage is -needed for each minute of sound, how many minutes all the calls in -Norway sums up to, and the cost of data storage.

- -

The 2005 numbers are from -digi.no, -the 2012 numbers are from -a -NKOM report, and I got the 2013 numbers after asking NKOM via -email. I was told the numbers for 2014 will be presented May 20th, -and decided not to wait for those, as I doubt they will be very -different from the numbers from 2013.

- -

The amount of data storage per minute sound depend on the wanted -quality, and for phone calls it is generally believed that 8 Kbit/s is -enough. See for example a -summary -on voice quality from Cisco for some alternatives. 8 Kbit/s is 60 -Kbytes/min, and this can be multiplied with the number of call minutes -to get the storage requirements.

- -

Storage prices varies a lot, depending on speed, backup strategies, -availability requirements etc. But a simple way to calculate can be -to use the price of a TiB-disk (around 1000 NOK / 120 EUR) and double -it to take space, power and redundancy into account. It could be much -higher with high speed and good redundancy requirements.

- -

But back to the question, What would it cost to store all phone -calls in Norway? Not much. Here is a small table showing the -estimated cost, which is within the budget constraint of most medium -and large organisations:

- - - - - - -
YearCall minutesSizePrice in NOK / EUR
200524 000 000 0001.3 PiB3 mill / 358 000
201218 000 000 0001.0 PiB2.2 mill / 262 000
201317 000 000 000950 TiB2.1 mill / 250 000
- -

This is the cost of buying the storage. Maintenance need to be -taken into account too, but calculating that is left as an exercise -for the reader. But it is obvious to me from those numbers that -recording the sound of all phone calls in Norway is not going to be -stopped because it is too expensive. I wonder if someone already is -collecting the data?

Tor - from its creators mouth 11 years ago

A little more than 11 years ago, one of the creators of Tor, and +the current President of the Tor +project, Roger Dingledine, gave a talk for the members of the +Norwegian Unix User group (NUUG).

Here is the video included for those of you using browsers with +HTML video and Ogg Theora support:

Isenkram with PackageKit support - new version 0.23 available in Debian unstable
+
25th May 2016
+

The isenkram +system is a user-focused solution in Debian for handling hardware +related packages. The idea is to have a database of mappings between +hardware and packages, and pop up a dialog suggesting for the user to +install the packages to use a given hardware dongle. Some use cases +are when you insert a Yubikey, it proposes to install the software +needed to control it; when you insert a braille reader list it +proposes to install the packages needed to send text to the reader; +and when you insert a ColorHug screen calibrator it suggests to +install the driver for it. The system work well, and even have a few +command line tools to install firmware packages and packages for the +hardware already in the machine (as opposed to hotpluggable hardware).

+ +

The system was initially written using aptdaemon, because I found +good documentation and example code on how to use it. But aptdaemon +is going away and is generally being replaced by +PackageKit, +so Isenkram needed a rewrite. And today, thanks to the great patch +from my college Sunil Mohan Adapa in the FreedomBox project, the +rewrite finally took place. I've just uploaded a new version of +Isenkram into Debian Unstable with the patch included, and the default +for the background daemon is now to use PackageKit. To check it out, +install the isenkram package and insert some hardware dongle +and see if it is recognised.

+ +

If you want to know what kind of packages isenkram would propose for +the machine it is running on, you can check out the isenkram-lookup +program. This is what it look like on a Thinkpad X230:

+ +

+% isenkram-lookup 
+bluez
+cheese
+fprintd
+fprintd-demo
+gkrellm-thinkbat
+hdapsd
+libpam-fprintd
+pidgin-blinklight
+thinkfan
+tleds
+tp-smapi-dkms
+tp-smapi-source
+tpb
+%p
+

+ +

The hardware mappings come from several places. The preferred way +is for packages to announce their hardware support using +the +cross distribution appstream system. +See +previous +blog posts about isenkram to learn how to do that.

Debian Edu interview: Shirish Agarwal
-
15th April 2015
-

It was a surprise to me to learn that project to create a complete -computer system for schools I've involved in, -Debian Edu / Skolelinux, was -being used in India. But apparently it is, and I managed to get an -interview with one of the friends of the project there, Shirish -Agarwal.

- -

Who are you, and how do you spend your days?

- -

My name is Shirish Agarwal. Based out of the educational and -historical city of Pune, from the western state of Maharashtra, India. -My bread comes from giving training, giving policy tips, -installations on free software to mom and pop shops in different -fields from Desktop publishing to retail shops as well as work with -few software start-ups as well.

- -

How did you get in contact with the Skolelinux / Debian Edu -project?

- -

It started innocently enough. I have been using Debian for a few -years and in one local minidebconf / debutsav I was asked if there was -anything for schools or education. I had worked / played with free -educational softwares such as Gcompris and Stellarium for my many -nieces and nephews so researched and found Debian Edu or Skolelinux as -it was known then. Since then I have started using the various -education meta-packages provided by the project.

- -

What do you see as the advantages of Skolelinux / Debian -Edu?

- -

It's closest I have seen where a package full of educational -software are packed, which are free and open (both literally and -figuratively). Even if I take the simplest software which is -gcompris, the number of activities therein are amazing. Another one of -the softwares that I have liked for a long time is stellarium. Even -pysycache is cool except for couple of issues I encountered -#781841 and -#781842.

- -

I prefer software installed on the system over web based solutions, -as a web site can disappear any time but the software on disk has the -possibility of a larger life span. Of course with both it's more a -question if it has enough users who make it fun or sustainable or both -for the developer per-se.

- -

What do you see as the disadvantages of Skolelinux / Debian -Edu?

- -

I do see that the Debian Edu team seems to be short-handed and I -think more efforts should be made to make it popular and ask and take -help from people and the larger community wherever possible.

- -

I don't see any disadvantage to use Skolelinux apart from the fact -that most apps. are generic which is good or bad how you see it. -However, saying that I do acknowledge the fact that the canvas is -pretty big and there are lot of interesting ideas that could be done -but for reasons not known not done or if done I don't know about them. -Let me share some of the ideas (these are more upstream based but -still) I have had for a long time :

- -

1. Classical maths question of two trains in opposing directions -each running @x kmph/mph at y distance, when they will meet and how -far would each travel and similar questions like these. - -

The computer is a fantastic system where questions like these can -be drawn, animated and the methodology and answers teased out in -interactive manner. While sites such as the -Ask -Dr. Math FAQ on The Two Trains problem (as an example or point of -inspiration) can be used there is lot more that can be done. I dunno -if there is a free software which does something like this. The idea -being a blend of objects + animation + interaction which does -this. The whole interaction could be gamified with points or sounds or -colourful celebration whenever the user gets even part of the question -or/and methodology right. That would help reinforce good behaviour. -This understanding could be used to share/showcase everything from how -the first wheel came to be, to evolution to how astronomy started, -psychics and everything in-between.

- -

One specific idea in the train part was having the Linux mascot on -one train and the BSD or GNU mascot on the other train and they -meeting somewhere in-between. Characters from blender movies could -also be used.

- -

2. Loads of crossword-puzzles with reference to subjects: We have -enormous data sets in Wikipedia and Wikitionary. I don't think it -should be a big job to design crossword puzzles. Using categories and -sub-categories it should be doable to have Q&A single word answers -from the existing data-sets. What would make it easy or hard could be -the length of the word + existence of many or few vowels depending on -the user's input.

- -

3. Jigsaw puzzles - We already have a great software called -palapeli with number of slicers making it pretty interesting. What -needs to be done is to download large number of public domain and -copyleft images, tease and use IPTC tags to categorise them into -nature, history etc. and let it loose. This could turn to be really -huge collection of images. One source could be taken from -commons.wikimedia.org, others could be huge collection of royalty-free -stock photos. Potential is immense.

- -

Apart from this, free software suffers in two directions, we lag -both in development (of using new features per-se) and maintenance a -lot. This is more so in educational software as these applications -need to be timely and the opportunity cost of missing deadlines is -immense. If we are able to solve issues of funding for development and -maintenance of such software I don't see any big difficulties. I know -of few start-ups in and around India who would love to develop and -maintain such software if funding issues could be solved.

- -

Which free software do you use daily?

- -

That would be huge list. Some of the softwares are obviously apt, -aptitude, debdelta, leafpad, the shell of course (zsh nowadays), -quassel for IRC. In games I use shisen-sho while card-games are evenly -between kpat and Aiselriot. In desktops it's a tie between -gnome-flashback and mate.

- -

Which strategy do you believe is the right one to use to -get schools to use free software?

- -

I think it should first start with using specific FOSS apps. in -whatever environment they are. If it's MS-Windows or Mac so be it. -Once they are habitual with the apps. and there is buy-in from the -school management then it could be installed anywhere. Most of the -people now understand the concept of a repository because of the -various online stores so it isn't hard to convince on that front.

- -

What is harder is having enough people with technical skills and -passion to service them. If you get buy-in from one or two teachers -then ideas like above could also be asked to be done as a project as -well.

- -

I think where we fall short more than anything is in marketing. For -instance, Debian has this whole range of fonts in its archive but -there isn't even a page where all those different fonts in the La -Ipsum format could be tried out for newcomers.

- -

One of the issues faced constantly in installations is with updates -and upgrades. People have this myth that each update and upgrade -means the user interface will / has to change. I have seen this -innumerable times. That perhaps is one of the reasons which browsers -like Iceweasel / Firefox change user interfaces so much, not because -it might be needed or be functional but because people believe that -changed user interfaces are better. This, can easily be pointed with -the user interfaces changed with almost every MS-Windows and Mac OS -releases.

- -

The problems with Debian Edu for deployment are many. The biggest -is the huge gap between what is taught in schools and what Debian Edu -is aimed at. - -

Me and my friends did teach on week-ends in a government school for -around 2 years, and -gathered -some experience there. Some of the things we learnt/discovered -there was :

- -
    - -
  1. Most of the teachers are very territorial about their subjects - and they do not want you to teach anything out of the - portion/syllabus given.
    2. - -
  2. They want any activity on the system in accordance to whatever - is in the syllabus.
    3. - -
  3. There are huge barriers both with the English language and at - times with objects or whatever. An example, let's say in gcompris - you have objects falling down and you have to name them and let's - say the falling object is a hat or a fedora hat, this would not be - as recognizable as say a - Puneri - Pagdi so there is need to inject local objects, words wherever - possible. Especially for word-games there are so many hindi words - which have become part of english vocabulary (for instance in - parley), those could be made into a hinglish collection or - something but that is something for upstream to do.

Discharge rate estimate in new battery statistics collector for Debian
+
23rd May 2016
+

Yesterday I updated the +battery-stats +package in Debian with a few patches sent to me by skilled and +enterprising users. There were some nice user and visible changes. +First of all, both desktop menu entries now work. A design flaw in +one of the script made the history graph fail to show up (its PNG was +dumped in ~/.xsession-errors) if no controlling TTY was available. +The script worked when called from the command line, but not when +called from the desktop menu. I changed this to look for a DISPLAY +variable or a TTY before deciding where to draw the graph, and now the +graph window pop up as expected.

+ +

The next new feature is a discharge rate estimator in one of the +graphs (the one showing the last few hours). New is also the user of +colours showing charging in blue and discharge in red. The percentages +of this graph is relative to last full charge, not battery design +capacity.

+ +

+ +

The other graph show the entire history of the collected battery +statistics, comparing it to the design capacity of the battery to +visualise how the battery life time get shorter over time. The red +line in this graph is what the previous graph considers 100 percent: + +

+ +

In this graph you can see that I only charge the battery to 80 +percent of last full capacity, and how the capacity of the battery is +shrinking. :(

+ +

The last new feature is in the collector, which now will handle +more hardware models. On some hardware, Linux power supply +information is stored in /sys/class/power_supply/ACAD/, while the +collector previously only looked in /sys/class/power_supply/AC/. Now +both are checked to figure if there is power connected to the +machine.

+ +

If you are interested in how your laptop battery is doing, please +check out the +battery-stats +in Debian unstable, or rebuild it on Jessie to get it working on +Debian stable. :) The upstream source is available from github. +Patches are very welcome.

+ +

As usual, if you use Bitcoin and want to show your support of my +activities, please send Bitcoin donations to my address +15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b.

21st May 2016
