- <description><p>When asked to accept terms of use and privacy policies that state

+<p>I 1979 leverte Ole-Erik Yrvin en hovedfagsoppgave for Cand. Scient.
+ ved Institutt for sosiologi på Universitetet i Oslo på oppdrag fra
+ Forbruker- og administrasjonsdepartementet. Oppgaven evaluerte
+ Angrefristloven fra 1972, og det han oppdaget førte til at loven ble
+ endret fire år senere.</p>
+
+<p>Jeg har kjent Ole-Erik en stund, og synes det var trist at hans
+ oppgave ikke lenger er tilgjengelig, hverken fra oppdragsgiver
+ eller fra universitetet. Hans forsøk på å få den avbildet og lagt
+ ut på Internett har vist seg fånyttes, så derfor tilbød jeg meg for
+ en stund tilbake å publisere den og gjøre den tilgjengelig med
+ fribruksvilkår på Internett. Det er nå klart, og hovedfagsoppgaven
+ er tilgjengelig blant annet via <a
+ href="http://www.hungry.com/~pere/publisher/">min liste over
+ publiserte bøker</a>, både som nettside,
+ <a href="https://www.lulu.com/search?contributor=Ole-Erik+Yrvin">digital
+ bok i ePub-format og på papir fra lulu.com</a>. Jeg regner med at
+ den også vil dukke opp på nettbokhandlere i løpet av en måned eller
+ to.</p>
+
+<p>Alle tabeller og figurer er gjenskapt for bedre lesbarhet, noen
+ skrivefeil rettet opp og mange referanser har fått flere detaljer
+ som ISBN-nummer og DOI-referanse. Selv om jeg ikke regner med at
+ dette blir en kioskvelter, så håper jeg denne nye utgaven kan komme
+ fremtiden til glede.</p>

- <title>What would it cost to store all 2018 phone calls in Norway?</title>

- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/What_would_it_cost_to_store_all_2018_phone_calls_in_Norway_.html</guid>
- <pubDate>Mon, 25 Nov 2019 20:15:00 +0100</pubDate>
- <description><p>Four years ago, I did a back of the envelope calculation on
-<a href="http://people.skolelinux.org/pere/blog/What_would_it_cost_to_store_all_phone_calls_in_Norway_.html">how
-much it would cost to store audio recordings of all the phone calls in
-Norway</a>, and came up with NOK 2.1 million / EUR 250 000 for the
-year 2013. It is time to repeat the calculation using updated
-numbers. The calculation is based on how much data storage is needed
-for each minute of audio, how many minutes all the calls in Norway
-sums up to, multiplied by the cost of data storage.</p>
-
-<p>The number of phone call minutes for 2018 was fetched from
-<a href="https://ekomstatistikken.nkom.no/">the NKOM statistics
-site</a>, and for 2018, land line calls are listed as 434 238 000
-minutes, while mobile phone calls are listed with 7 542 006 000
-minutes. The total number of minutes is thus 7 976 244 000. For
-simplicity, I decided to ignore any advantages in audio compression the
-last four years, and continue to assume 60 Kbytes/min as the last
-time.</p>
-
-<p>Storage prices still varies a lot, but as last time, I decide to
-take a reasonable big and cheap hard drive, and double its price to
-include the surrounding costs into account. A 10 TB disk cost less
-than 4500 NOK / 450 EUR these days, and doubling it give 9000 NOK per
-10 TB.</p>
-
-<p>So, with the parameters in place, lets update the old table
-estimating cost for calls in a given year:</p>
-
-<table border="1">
-<tr><th>Year</th><th>Call minutes</th><th>Size</th><th>Price in NOK / EUR</th></tr>
-<tr><td>2005</td><td align="right">24 000 000 000</td><td align="right">1.3 PiB</td><td align="right">1 170 000 / 117 000</td></tr>
-
-<tr><td>2012</td><td align="right">18 000 000 000</td><td align="right">1.0 PiB</td><td align="right">900 000 / 90 000</td></tr>
-
-<tr><td>2013</td><td align="right">17 000 000 000</td><td align="right">950 TiB</td><td align="right">855 000 / 85 500</td></tr>
-
-<tr><td>2018</td><td align="right">7 976 244 000</td><td align="right">445 TiB</td><td align="right">401 100 / 40 110</td></tr>
-</table>
-
-<p>Both the cost of storage and the number of phone call minutes have
-dropped since the last time, bringing the cost down to a level where I
-guess even small organizations can afford to store the audio recording
-from every phone call taken in a year in Norway. Of course, this is
-just the cost of buying the storage equipment. Maintenance, need to
-be included as well, but the volume of a single year is about a single
-rack of hard drives, so it is not much more than I could fit in my own
-home. Wonder how much the electricity bill would raise if I had that
-kind of storage? I doubt it would be more than a few tens of thousand
-NOK per year.</p>

+ <description><p>Medlemmene av Norges regjering har demonstert de siste månedene at
+habilitetsvureringer ikke er deres sterke side og det gjelder både
+Arbeiderpartiets og Senterpartiers representater. Det er heldigvis
+enklere i det private, da inhabilitetsreglene kun gjelder de som
+jobber for folket, ikke seg selv. Sist ut er utenriksminister
+Huitfeldt. I går kom nyheten om at
+<a href="https://www.nrk.no/nyheter/riksadvokaten_-okokrim-nestsjef-kan-behandle-huitfeldt-saken-1.16545162">Riksadvokaten
+har konkludert med at nestsjefen i Økokrim kan behandle sak om
+habilitet og innsidekunnskap</a> for Huitfeldt, på tross av at hans
+overordnede, sjefen for Økokrim, har meldt seg inhabil i saken. Dette
+er litt rart. I veilednigen
+«<a href="https://www.regjeringen.no/globalassets/upload/krd/vedlegg/komm/veiledere/habilitet_i_kommuner_og_fylkeskommuner.pdf">Habilitet
+i kommuner og fylkeskommuner</a>» av Kommunal- og regionaldepartementet
+forteller de hva som gjelder, riktig nok gjelder veiledningen ikke for
+Økokrim som jo ikke er kommune eller fylkeskommune, men jeg får ikke
+inntrykk av at dette er regler som kun gjelder for kommune og
+fylkeskommune:
+
+<blockquote>
+<p>«<strong>2.1 Oversikt over inhabilitetsgrunnlagene</strong>
+
+<p>De alminnelige reglene om inhabilitet for den offentlige
+forvaltningen er gitt i
+<a href="https://lovdata.no/dokument/NL/lov/1967-02-10/KAPITTEL_2#KAPITTEL_2">forvaltningsloven
+§§ 6 til 10</a>. Forvaltningslovens hovedregel om inhabilitet framgår
+av § 6. Her er det gitt tre ulike grunnlag som kan føre til at en
+tjenestemann eller folkevalgt blir inhabil. I § 6 første ledd
+bokstavene a til e er det oppstilt konkrete tilknytningsforhold mellom
+tjenestemannen og saken eller sakens parter som automatisk fører til
+inhabilitet. Annet ledd oppstiller en skjønnsmessig regel om at
+tjenestemannen også kan bli inhabil etter en konkret vurdering av
+inhabilitetsspørsmålet, der en lang rekke momenter kan være
+relevante. I tredje ledd er det regler om såkalt avledet
+inhabilitet. Det vil si at en underordnet tjenestemann blir inhabil
+fordi en overordnet er inhabil.»</p>
+</blockquote>
+
+<p>Loven sier ganske enkelt «Er den overordnede tjenestemann ugild,
+kan avgjørelse i saken heller ikke treffes av en direkte underordnet
+tjenestemann i samme forvaltningsorgan.» Jeg antar tanken er at en
+underordnet vil stå i fare for å tilpasse sine konklusjoner til det
+overordnet vil ha fordel av, for å fortsatt ha et godt forhold til sin
+overordnede. Men jeg er ikke jurist og forstår nok ikke kompliserte
+juridiske vurderinger. For å sitere «Kamerat Napoleon» av George
+Orwell: «Alle dyr er like, men noen dyr er likere enn andre».

- <title>Norwegian movies that might be legal to share on the Internet</title>

- <description><p>While working on identifying and counting movies that can be
-legally shared on the Internet, I also looked at the Norwegian movies
-listed in IMDb. So far I have identified 54 candidates published
-before 1940 that might no longer be protected by norwegian copyright
-law. Of these, only 29 are available at least in part from the
-Norwegian National Library. It can be assumed that the remaining 25
-movies are lost. It seem most useful to identify the copyright status
-of movies that are not lost. To verify that the movie is really no
-longer protected, one need to verify the list of copyright holders and
-figure out if and when they died. I've been able to identify some of
-them, but for some it is hard to figure out when they died.</p>
-
-</p>This is the list of 29 movies both available from the library and
-possibly no longer protected by copyright law. The year range
-(1909-1979 on the first line) is year of publication and last year
-with copyright protection.</p>

-1939-2009 ( 70 year) Til Vesterheimen - http://www.imdb.com/title/tt0032036/
-</pre>
-
-To be sure which one of these can be legally shared on the Internet,
-in addition to verifying the right holders list is complete, one need
-to verify the death year of these persons:
-
-<pre>
-Bjørnstjerne Bjørnson (dead 1910) - http://www.imdb.com/name/nm0085085/
-Gustav Adolf Olsen (missing death year) - http://www.imdb.com/name/nm0647652/
-Gustav Lund (missing death year) - http://www.imdb.com/name/nm0526168/
-John W. Brunius (dead 1937) - http://www.imdb.com/name/nm0116307/
-Ola Cornelius (missing death year) - http://www.imdb.com/name/nm1227236/
-Oskar Omdal (dead 1927) - http://www.imdb.com/name/nm3116241/
-Paul Berge (missing death year) - http://www.imdb.com/name/nm0074006/
-Peter Lykke-Seest (dead 1948) - http://www.imdb.com/name/nm0528064/

-Thomas W. Schwartz (missing death year) - http://www.imdb.com/name/nm2616250/
-</pre>
-
-<p>Perhaps you can help me figuring death year of those missing it, or
-right holders if some are missing in IMDb? It would be nice to have a
-definite list of Norwegian movies that are legal to share on the
-Internet.</p>

-<p>Several of these movies completely lack right holder information in
-IMDb and elsewhere. Without access to a copy of the movie, it is
-often impossible to get the list of people involved in making the
-movie, making it impossible to figure out the correct copyright
-status.</p>
-
-<p>Not listed here are the movies still protected by copyright law.
-Their copyright terms varies from 79 to 144 years, according to the
-information I have available so far. One of the non-lost movies might
-change status next year,
-<a href="https://www.imdb.com/title/tt1008007/">Mustads Mono from 1920</a>.

+ <description><p>I still enjoy <a href="https://kodi.tv/">Kodi</a> and
+<a href="https://libreelec.tv/">LibreELEC</a> as my multimedia center
+at home. Sadly two of the services I really would like to use from
+within Kodi are not easily available. The most wanted add-on would be
+one making <a href="https://archive.org/">The Internet Archive</a>
+available, and it has
+<a href="https://kodi.wiki/view/Add-on:Internet_Archive">not been
+working</a> for many years. The second most wanted add-on is one
+using <a href="https://invidious.io/">the Invidious privacy enhanced
+Youtube frontent</a>. A plugin for this has been partly working, but
+not been kept up to date in the Kodi add-on repository, and its
+upstream seem to have given it up in April this year, when the git
+repository was closed. A few days ago I got tired of this sad state
+of affairs and decided to
+<a href="https://github.com/petterreinholdtsen/kodi-invidious-plugin">have
+a go at improving the Invidious add-on</a>. As
+<a href="https://github.com/iv-org/invidious/issues/3872">Google has
+already attacked</a> the Invidious concept, so it need all the support
+if can get. My small contribution here is to improve the service
+status on Kodi.</p>
+
+<p>I added support to the Invidious add-on for automatically picking a
+working Invidious instance, instead of requiring the user to specify
+the URL to a specific instance after installation. I also had a look
+at the set of patches floating around in the various forks on github,
+and decided to clean up at least some of the features I liked and
+integrate them into my new release branch. Now the plugin can handle
+channel and short video items in search results. Earlier it could
+only handle single video instances in the search response. I also
+brushed up the set of metadata displayed a bit, but hope I can figure
+out how to get more relevant metadata displayed.</p>
+
+<p>Because I only use Kodi 20 myself, I only test on version 20 and am
+only motivated to ensure version 20 is working. Because of API changes
+between version 19 and 20, I suspect it will fail with earlier Kodi
+versions.</p>
+
+<p>I already
+<a href="https://github.com/xbmc/repo-plugins/pull/4363">asked to have
+the add-on added</a> to the official Kodi 20 repository, and is
+waiting to heard back from the repo maintainers.</p>

-books published in the USA that are now in the public domain</a>,
-inspired me to update the scripts I use to track down movies that are
-in the public domain. This involved updating the script used to
-extract lists of movies believed to be in the public domain, to work
-with the latest version of the source web sites. In particular the
-new edition of the <a href="https://retrofilmvault.com/">Retro Film
-Vault</a> web site now seem to list all the films available from that
-distributor, bringing the films identified there to more than 12.000
-movies, and I was able to connect 46% of these to IMDB titles.</p>
-
-<p>The new total is 16307 IMDB IDs (aka films) in the public domain or
-creative commons licensed, and unknown status for 31460 movies
-(possibly duplicates of the 16307).</p>

+ <description><p>With yesterdays
+<a href="https://www.debian.org/News/2023/20230610">release of Debian
+12 Bookworm</a>, I am happy to know the
+<a href="https://tracker.debian.org/pkg/opensnitch">the interactive
+application firewall OpenSnitch</a> is available for a wider audience.
+I have been running it for a few weeks now, and have been surprised
+about some of the programs connecting to the Internet. Some programs
+are obviously calling out from my machine, like the NTP network based
+clock adjusting system and Tor to reach other Tor clients, but others
+were more dubious. For example, the KDE Window manager try to look up
+the host name in DNS, for no apparent reason, but if this lookup is
+blocked the KDE desktop get periodically stuck when I use it. Another
+surprise was how much Firefox call home directly to mozilla.com,
+mozilla.net and googleapis.com, to mention a few, when I visit other
+web pages. This direct connection happen even if I told Firefox to
+always use a proxy, and the proxy setting is ignored for this traffic.
+Other surprising connections come from audacity and dirmngr (I do not
+use Gnome). It took some trial and error to get a good default set of
+permissions. Without it, I would get popups asking for permissions at
+any time, also the most inconvenient ones where I am in the middle of
+a time sensitive gaming session.</p>
+
+<p>I suspect some application developers should rethink when then need
+to use network connections or DNS lookups, and recommend testing
+OpenSnitch (only <tt>apt install opensnitch</tt> away in Debian
+Bookworm) to locate and report any surprising Internet connections on
+your desktop machine.</p>
+
+<p>At the moment the upstream developer and Debian package maintainer
+is working on making the system more reliable in Debian, by enabling
+the eBPF kernel module to track processes and connections instead of
+depending in content in /proc/. This should enter unstable fairly
+soon.</p>

- <description><p>Jeg er veldig glad for å kunne fortelle at i går ble ny versjon av
-<a href="https://www.arkivverket.no/forvaltning-og-utvikling/noark-standarden/noark-5/tjenestegrensesnitt-noark5">API-spesifikasjonen
-for Noark 5 Tjenestegrensesnitt</a> gitt ut. Det så lenge mørkt ut
-for sjansene for å få inn nødvendige korreksjoner i
-spesifikasjonsteksten innen rimelig tid, men takket være intens og god
-innsats fra Mona og Anne Sofie hos Arkivverket de siste ukene, så ble
-resultatet som ble gitt ut på USAs uavhengighetsdag mye bedre enn jeg
-fryktet.</p>
-
-<p>Spesifikasjonen er
-<a href="https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/">tilgjengelig
-som markdown-filer i Arkivverkets github-prosjekt for dette</a>, og de
-aller fleste av forslagene til forbedringer fra oss som holder på med
-<a href="https://gitlab.com/OsloMet-ABI/nikita-noark5-core">Nikita-prosjektet</a>
-kom med i denne nye og oppdaterte spesifikasjonsteksten. Det er
-fortsatt mye som gjenstår før den er entydig, klar og sikrer samvirke
-på tvers av leverandører, men utgangspunktet er veldig mye bedre enn
-forrige versjon fra 2016. Ta gjerne en titt.</p>
-
-<p>Ellers må jeg jo si at det var hyggelig å se at min forrige
-bloggpost om tjenestegrensesnittet fikk en
-<a href="https://beta.arkivverket.no/post/186020592045/noark-5-versjon-50-tjenestegrensesnitt-10">lenke

+ <description><p>There is a European standard for reading utility meters like water,
+gas, electricity or heat distribution meters. The
+<a href="https://en.wikipedia.org/wiki/Meter-Bus">Meter-Bus standard
+(EN 13757-2, EN 13757-3 and EN 13757–4)</a> provide a cross vendor way
+to talk to and collect meter data. I ran into this standard when I
+wanted to monitor some heat distribution meters, and managed to find
+free software that could do the job. The meters in question broadcast
+encrypted messages with meter information via radio, and the hardest
+part was to track down the encryption keys from the vendor. With this
+in place I could set up a MQTT gateway to submit the meter data for
+graphing.</p>
+
+<p>The free software systems in question,
+<a href="https://tracker.debian.org/pkg/rtl-wmbus">rtl-wmbus</a> to
+read the messages from a software defined radio, and
+<a href="https://tracker.debian.org/pkg/wmbusmeters">wmbusmeters</a> to
+decrypt and decode the content of the messages, is working very well
+and allowe me to get frequent updates from my meters. I got in touch
+with upstream last year to see if there was any interest in publishing
+the packages via Debian. I was very happy to learn that Fredrik
+Öhrström volunteered to maintain the packages, and I have since
+assisted him in getting Debian package build rules in place as well as
+sponsoring the packages into the Debian archive. Sadly we completed
+it too late for them to become part of the next stable Debian release
+(Bookworm). The wmbusmeters package just cleared the NEW queue. It
+will need some work to fix a built problem, but I expect Fredrik will
+find a solution soon.</p>
+
+<p>If you got a infrastructure meter supporting the Meter Bus
+standard, I strongly recommend having a look at these nice
+packages.</p>

-
-<p>The 24 page booklet titled Digital Defenders is

+ <description><p>The LinuxCNC project is making headway these days. A lot of
+patches and issues have seen activity on
+<a href="https://github.com/LinuxCNC/linuxcnc/">the project github
+pages</a> recently. A few weeks ago there was a developer gathering
+over at the <a href="https://tormach.com/">Tormach</a> headquarter in
+Wisconsin, and now we are planning a new gathering in Norway. If you
+wonder what LinuxCNC is, lets quote Wikipedia:</p>
+
+<blockquote>
+"LinuxCNC is a software system for numerical control of
+machines such as milling machines, lathes, plasma cutters, routers,
+cutting machines, robots and hexapods. It can control up to 9 axes or
+joints of a CNC machine using G-code (RS-274NGC) as input. It has
+several GUIs suited to specific kinds of usage (touch screen,
+interactive development)."
+</blockquote>
+<p>The Norwegian developer gathering take place the weekend June 16th
+to 18th this year, and is open for everyone interested in contributing
+to LinuxCNC. Up to date information about the gathering can be found
+in
+<a href="https://sourceforge.net/p/emc/mailman/emc-developers/thread/sa64jp06nob.fsf%40hjemme.reinholdtsen.name/#msg37837251">the

- <title>Nikita og Noark 5 tjenestegrensesnittet tilbyr ny måte å tenke arkivering</title>

- <description><p><em>av Thomas Sødring (OsloMet) og Petter Reinholdtsen (foreningen
-NUUG)</em></p>
-
-<p>Nikita Noark 5-kjerne er et fri programvareprosjekt som tar i bruk
-Arkivverkets spesifikasjonen for Noark 5 Tjenestegrensesnitt og tilbyr
-et maskinlesbart grensesnitt (arkiv-API) til datasystemer som trenger å
-arkivere dokumenter og informasjon. I tillegg tilbyr Nikita et
-nettleserbasert brukergrensesnitt for brukere av arkivet. Dette
-brukergrensesnittet benytter det maskinlesbare grensesnittet. Noark 5
-Tjenestegrensesnitt er en ny måte å tenke arkivering, med fokus på
-automatisering og maskinell behandling av arkivmateriale, i stedet for
-å fokusere på brukergrensesnitt. En kan tenke på
-tjenestegrensesnittet som arkivet uten brukergrensesnitt, der flere
-aktører kan koble til ulike brukergrensesnitt, tilpasset ulike
-behov.</p>
-
-<p>Historisk sett gjorde Noark standarden en veldig bra jobb med
-overgangen fra
-papir til digital saksbehandling, men det har kommet til kort på andre
-områder. Den teknologiske utviklingen har brakt oss ditt at vi kan og
-skal forvente langt mer fra en arkivkjerne enn før, men det offentlig
-er ofte konservativ når det gjelder nytenking. For lengst skulle
-begreper som samvirke mellom datasystemer, metadata, prosess og
-tjenestegrensesnitt (API) vært dominerende når systemer kjøpes
-inn. Dessverre er det slik at ikke alle ønsker samvirke mellom
-datasystemer velkommen, og det kan være trygt å kjøpe «svarte bokser»
-der du slipper å ta stilling til hvordan man skal få flere systemer
-til å virke sammen. Men IT-arkitektur er et begrep arkivfolk også
-begynner å ta inn over seg.</p>
-
-<p>Slike systemer for å organisere metadata bør ha nettbaserte
-tjenestegrensesnitt der brukergrensesnitt er tydelig adskilt fra
-bakenforliggende system. Det finnes mange rapporter som snakker om å
-bryte ned siloer i forvaltningen og standardiserte tjenestegrensesnitt
-er det viktigste virkemiddel mot datasiloer og legger til rette for
-økt samvirke mellom systemer. Et standardisert tjenestegrensesnitt er
-et viktig middel for å få systemer til å samhandle da det sikrer at
-ulike produsenters systemer kan snakke sammen på tvers. Samfunnet
-fungerer ikke uten standardisering. Vi har alle samme strømstyrke og
-kontakter i veggene og kjører alle på høyre side av veien i Norge. Det er i en slik
-sammenheng at prosjektet «Noark 5 Tjenestegrensesnitt» er veldig
-viktig. Hvis alle leverandører av arkivsystemer forholdt seg til et
-standardisert tjenestegrensesnitt kunne kostnadene for arkivering
-reduseres. Tenk deg at du er en kommune som ønsker et fagsystem integrert
-med arkivløsningen din. I dag må fagsystemleverandøren vite og
-tilpasse seg den spesifikke versjonen og varianten av arkivløsningen
-du har. Hvis vi antar at alle leverandører av arkivkjerner har solgt
-inn enten SOAP eller REST-grensesnitt til kunder de siste 10 årene og
-det kommer endret versjon av grensesnittet innimellom, så gir det
-veldig mange forskjellige tjenestegrensesnitt en fagsystemleverandør
-må forholde seg til. Med 12 leverandører og kvartalsvise oppdateringer
-kan det potensielt bli 96 ulike varianter hvert eneste år. Det sier
-seg selv at det blir dyrt. Men det blir faktisk verre. Hvis du senere
-ønsker å bytte ut arkivsystemet med et annet så er du avhengig å få
-alle integrasjonene dine laget på nytt. Dette kan gjøre at du velger å
-forbli hos en dårlig leverandør framfor å skaffe nytt system, fordi
-det blir for vanskelig og dyrt å bytte. Dermed etableres det «små»
-monopolsituasjoner som er vanskelig å bryte ut av. Dårlige valg i dag
-kan ha uante kostander på sikt. I Nikita-prosjektet har vi kun jobbet
-opp mot Noark 5 Tjenestegrensesnittet. Det har tatt en god del
-ressurser å sette seg inn i spesifikasjonen og ta den i bruk, spesielt
-på grunn av uklarheter i spesifikasjonen. Hvis vi måtte gjøre det
-samme for alle versjoner og varianter av de forskjellige
-tjenestegrensesnittene ville det blitt veldig tidkrevende og
-kostbart.</p>
-
-<p>For deg som arkivar er digitalisering og systemer som skal virke
-sammen en del av den nye hverdagen. Du har kanskje blitt skånet for
-det ved å kjøpe svarte bokser, men du risikerer at du gjør deg selv en
-bjørnetjeneste. Det kan oppleves som kjedelig å fortelle kolleger at
-du skal sette deg inn i et tjenestegrensesnitt, men dette er faktisk
-veldig spennende. Tjenestegrensesnittet er på en måte blitt levende og
-det er spesielt et begrep du bør merke deg: OData. Å trekke inn deler
-av OData-standarden som en måte å filtrere entitetsøk i et arkivsystem
-var et nyttig trekk i prosjektet. Følgende eksempel er en
-OData-spørring det går an å sende inn til en standardisert
-arkivkjerne:</p>
-
-<p><blockquote>
-.../sakarkiv/journalpost?filter=contains(tittel, 'nabovarsel')
-</blockquote></p>
-
-<p>Spørringen over vil hente en liste av alle dine journalposter der
-tittelen til journalposten inneholder ordet 'nabovarsel'. Alle
-leverandører som implementerer tjenestegrensesnittet vil måtte tilby
-dette. Det betyr at hvis du lærer dette språket for et system, vil det
-være gjeldende for alle. Dette er egentlig en ny måte å søke i
-arkivdatabasen på og vil være svært nyttig, for eksempel kan søk i
-tjenestegrensesnittet antagelig brukes til å hente ut offentlig
-postjournal. I arkivverden pleier vi å like teknologier som er
-menneskelesbart, da vet vi det er enkelt og nyttig! OData er også
-viktig fordi det kan bli en ny måte å svare innsynsforespørsler på i
-tråd med offentlighetsloven § 9, der retten til å kreve innsyn i
-sammenstilling fra databaser er nedfelt. I dag ser vi
-forvaltningsorganer som avviser slike krav fordi det «ikke kan gjøres
-med enkle framgangsmåter». Bruken av OData i tjenestegrensesnittet,
-sammen med maskinlesbar markeringsformater kan være et viktig bidrag
-til å åpne arkivene i tråd med prinsippene om en åpen og transparent
-forvaltning.</p>
-
-<p>Standardisering er viktig fordi det <em>kan</em> sikre samvirke.
-Men den effekten kommer kun hvis standardiseringen sikrer at alle
-forstår standarden på samme måte, dvs. at den er entydig og klar. En
-god måte å sikre en entydig og klar spesifikasjon er ved å kreve at
-det finnes minst to ulike implementasjoner som følger spesifikasjonen
-og som kan snakke sammen, det vil si at de snakker samme språk, slik
-IETF krever for alle sine standarder, før spesifikasjonen anses å være
-ferdig. Tilbakemelding fra miljøet forteller at både leverandører og
-kunder har et avslappet forhold til Noark 5 Tjenestegrensesnitt og det
-er så langt kun Evry som har visst offentlig at de har en
-implementasjon av tjenestegrensesnittet. Evry, HK Data og Fredrikstad
-kommune er igang med et pilotprosjekt på Noark 5
-Tjenestegrensesnitt. For å redusere kostnadene for samvirkende
-datasystemer betraktelig, er det veldig viktig at vi kommer i en
-situasjon der alle leverandører har sine egne implementasjoner av
-tjenestegrensesnittet, og at disse oppfører seg likt og i tråd med det
-som er beskrevet i spesifikasjonen.</p>
-
-<p>Det er her fri programvare spiller en viktig rolle. Med en uklar
-standard blir det som en polsk riksdag, der ingenting fungerer. Nikita
-er en fri programvareimplementasjon av tjenestegrensesnitt og kan
-fungere som teknisk referanse slik at leverandører enklere kan se og
-forstå hvordan standarden skal tolkes. Vi har i Nikitaprosjektet
-erfart å ende opp med vidt forskjellige tolkninger når
-prosjektmedlemmene leser spesifikasjonsteksten, en effekt av en uklar
-spesifikasjon. Men Nikitaprosjektet har også utviklet et test-program
-som sjekker om et tjenestegrensesnitt er i samsvar med standarden, og
-prosjektet bruker det hele tiden for å sikre at endringer og
-forbedringer fungerer. Egenerklæringsskjemaenes dager kan være talte!
-Snart vil du selv kunne teste hver oppdatering av arkivsystemet med en
-uavhengig sjekk.</p>
-
-<p>Fri programvare representerer en demokratisering av kunnskap der
-tolkning- og innlåsingsmakt flyttes fra leverandør til allmenheten.
-Med fri programvare har du en litt annerledes verdikjede, der selve
-produktet ikke holdes hemmelig for å tjene penger, slik en gjør med
-ufri programvare og skytjenester som ikke bruker fri programvare, men
-du kan tjene penger på andre deler av verdikjeden. Med fri programvare
-kan samfunnet betale for å videreutvikle nyttig
-fellesfunksjonalitet.</p>
-
-<p>Nikita er en fri programvareimplementasjon av tjenestegrensesnittet og
-kan fungere som en referanseimplementasjon dersom det er ønskelig.
-Alle har lik tilgang til koden og det koster ingenting å ta den i bruk
-og utforske det. Nikitaprosjektet ønsker tjenestegrensesnittet
-velkommen og stiller veldig gjerne opp i diskusjoner om tolkning av
-tjenestegrensesnittet. Nikita er bygget på moderne
-programmeringsrammeverk og utviklet i full åpenhet. Men Nikita er ikke
-noe du kan kjøpe. Nikita er først og fremst et verktøy for forsking og
-utvikling laget for å fremme forskning på arkivfeltet. Systemer som
-virker sammen har alltid vært hovedfokus og vil være det fremover.
-Det brukes som undervisningsverktøy der studentene ved OsloMet lærer
-om administrativt oppsett, saksbehandling, uttrekk og samvirkende
-datasystemer. Det brukes også som forskningsobjekt der vi ser på
-import av dokumentsamlinger, bruk av blokkjede og andre nyskapende
-måter å tenke arkiv på. Det er dog helt greit om andre tar Nikita og
-pakker det for å selge det som produkt. Forvaltningsorganer med
-sterke drift- og utviklingsmiljøer kan også se på Nikita og utforske
-hva som er mulig. Dette kan de gjøre uten å måtte betale for
-bruksrettigheter eller tilgang til konsulenter. Men arkivering blir
-ikke gratis på grunn av Nikita. Det trengs fortsatt folk med
-kompetanse og tid til å ta i bruk Nikita.</p>
-
-<p>Nikita har nylig kommet med en ny utgave, den sjette i rekken.
-Systemet er ikke ferdig, mest på grunn av at API-spesifikasjonen for
-Noark 5 Tjenestegrensesnitt ikke er ferdig, men allerede i dag kan en
-bruke Nikita som arkiv. Vi har laget eksempelsystem for å importere
-data fra deponi-XML og slik gjøre eksisterende arkivdata tilgjengelig
-via et API. Vi har også laget en testklient som importerer epost inn
-i arkivet med vedlegg der epostenes trådinformasjon brukes til å legge
-eposttråder i samme arkivmappe, og en annen testklient som henter
-epost ut av en arkivmappe på mbox-format slik at en vanlig epostklient
-kan brukes til å lese igjennom og svare på epostene i en
-arkivmappe. De som vil ta en titt på Nikita kan besøke
-<a href="https://nikita.oslomet.no">https://nikita.oslomet.no</a> og
-logge inn med brukernavn «admin@example.com» og passord «password».
-Dette gir tilgang til det forenklede brukergrensesnittet som brukes
-til undervisning. De som heller vil ta en titt under panseret kan
-besøke
-<a href="https://nikita.oslomet.no/browse.html">https://nikita.oslomet.no/browse.html</a>
-og der se hvordan API-et fungerer mer i detalj. Innloggingsdetaljer
-her er det samme som for brukergrensesnittet.</p>
-
-<p>Fremover er fokuset på forbedring av spesifikasjonen Noark 5
-Tjenestegrensesnitt. De som skrev tjenestegrensesnittet gjorde et
-interessant og framtidsrettet grep, de skilte sak fra arkiv.
-Tjenestegrensesnittet består av flere "pakker", der noen er
-grunnleggende mens andre bygger på de grunnleggende pakkene. Pakkene
-som er beskrevet så langt heter «arkivstruktur», «sakarkiv»,
-«administrasjon», «loggogsporing» og «moeter» (dessverre
-<a href="https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/pull/120">planlagt
-fjernet</a> i første utgave). Etter hvert håper vi å utforske
-prosses- og metadatabeskrivelser til flere fagområder og bidra til at
-tjenestegrensesnittet kan legge til flere pakker som «byggarkiv»,
-«barnevern», «personal», «barnehage», der arkivfaglig metadata- og
-dokumentasjonsbehov er kartlagt og standardisert.</p>
-
-<p>Nikita utvikles av en liten prosjektgruppe, og vi er alltid
-interessert å bli flere. Hvis en åpen, fri og standardisert tilnærming
-til arkivering høres interessant ut, bli med oss på veien videre. Vi
-er tilstede på IRC-kanalen #nikita hos FreeNode (tilgjengelig via
-nettleser på
-<a href="https://webchat.freenode.net?channels=#nikita">https://webchat.freenode.net?channels=#nikita</a>),
-og har en e-postliste nikita-noark@nuug.no hos NUUG (tilgjengelig for
-påmelding og arkiv på
-<a href="https://lists.nuug.no/mailman/listinfo/nikita-noark">https://lists.nuug.no/mailman/listinfo/nikita-noark</a>)
-der en kan følge med eller være med oss på den spennende veien videre.

+ <description><p>A bit delayed,
+<a href="https://tracker.debian.org/pkg/opensnitch">the interactive
+application firewall OpenSnitch</a> package in Debian now got the
+latest fixes ready for Debian Bookworm. Because it depend on a
+package missing on some architectures, the autopkgtest check of the
+testing migration script did not understand that the tests were
+actually working, so the migration was delayed. A bug in the package
+dependencies is also fixed, so those installing the firewall package
+(opensnitch) now also get the GUI admin tool (python3-opensnitch-ui)
+installed by default. I am very grateful to Gustavo Iñiguez Goya for
+his work on getting the package ready for Debian Bookworm.</p>
+
+<p>Armed with this package I have discovered some surprising
+connections from programs I believed were able to work completly
+offline, and it has already proven its worth, at least to me. If you
+too want to get more familiar with the kind of programs using
+Internett connections on your machine, I recommend testing <tt>apt
+install opensnitch</tt> in Bookworm and see what you think.</p>
+
+<p>The package is still not able to build its eBPF module within
+Debian. Not sure how much work it would be to get it working, but
+suspect some kernel related packages need to be extended with more
+header files to get it working.</p>

- <title>Jami/Ring, finally functioning peer to peer communication client</title>
- <link>http://people.skolelinux.org/pere/blog/Jami_Ring__finally_functioning_peer_to_peer_communication_client.html</link>
- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Jami_Ring__finally_functioning_peer_to_peer_communication_client.html</guid>
- <pubDate>Wed, 19 Jun 2019 08:50:00 +0200</pubDate>
- <description><p>Some years ago, in 2016, I
-<a href="http://people.skolelinux.org/pere/blog/Experience_and_updated_recipe_for_using_the_Signal_app_without_a_mobile_phone.html">wrote
-for the first time about</a> the Ring peer to peer messaging system.
-It would provide messaging without any central server coordinating the
-system and without requiring all users to register a phone number or
-own a mobile phone. Back then, I could not get it to work, and put it
-aside until it had seen more development. A few days ago I decided to
-give it another try, and am happy to report that this time I am able
-to not only send and receive messages, but also place audio and video
-calls. But only if UDP is not blocked into your network.</p>
-
-<p>The Ring system changed name earlier this year to
-<a href="https://en.wikipedia.org/wiki/Jami_(software)">Jami</a>. I
-tried doing web search for 'ring' when I discovered it for the first
-time, and can only applaud this change as it is impossible to find
-something called Ring among the noise of other uses of that word. Now
-you can search for 'jami' and this client and
-<a href="https://jami.net/">the Jami system</a> is the first hit at
-least on duckduckgo.</p>
-
-<p>Jami will by default encrypt messages as well as audio and video
-calls, and try to send them directly between the communicating parties
-if possible. If this proves impossible (for example if both ends are
-behind NAT), it will use a central SIP TURN server maintained by the
-Jami project. Jami can also be a normal SIP client. If the SIP
-server is unencrypted, the audio and video calls will also be
-unencrypted. This is as far as I know the only case where Jami will
-do anything without encryption.</p>
-
-<p>Jami is available for several platforms: Linux, Windows, MacOSX,
-Android, iOS, and Android TV. It is included in Debian already. Jami
-also work for those using F-Droid without any Google connections,
-while Signal do not.
-<a href="https://git.jami.net/savoirfairelinux/ring-project/wikis/technical/Protocol">The
-protocol</a> is described in the Ring project wiki. The system uses a
-distributed hash table (DHT) system (similar to BitTorrent) running
-over UDP. On one of the networks I use, I discovered Jami failed to
-work. I tracked this down to the fact that incoming UDP packages
-going to ports 1-49999 were blocked, and the DHT would pick a random
-port and end up in the low range most of the time. After talking to
-the developers, I solved this by enabling the dhtproxy in the
-settings, thus using TCP to talk to a central DHT proxy instead of
-
-peering directly with others. I've been told the developers are
-working on allowing DHT to use TCP to avoid this problem. I also ran
-into a problem when trying to talk to the version of Ring included in
-Debian Stable (Stretch). Apparently the protocol changed between
-beta2 and the current version, making these clients incompatible.
-Hopefully the protocol will not be made incompatible in the
-future.</p>
-
-<p>It is worth noting that while looking at Jami and its features, I
-came across another communication platform I have not tested yet. The
-<a href="https://en.wikipedia.org/wiki/Tox_(protocol)">Tox protocol</a>
-and <a href="https://tox.chat/">family of Tox clients</a>. It might
-become the topic of a future blog post.</p>

+ <description><p>While visiting a convention during Easter, it occurred to me that
+it would be great if I could have a digital Dictaphone with
+transcribing capabilities, providing me with texts to cut-n-paste into
+stuff I need to write. The background is that long drives often bring
+up the urge to write on texts I am working on, which of course is out
+of the question while driving. With the release of
+<a href="https://github.com/openai/whisper/">OpenAI Whisper</a>, this
+seem to be within reach with Free Software, so I decided to give it a
+go. OpenAI Whisper is a Linux based neural network system to read in
+audio files and provide text representation of the speech in that
+audio recording. It handle multiple languages and according to its
+creators even can translate into a different language than the spoken
+one. I have not tested the latter feature. It can either use the CPU
+or a GPU with CUDA support. As far as I can tell, CUDA in practice
+limit that feature to NVidia graphics cards. I have few of those, as
+they do not work great with free software drivers, and have not tested
+the GPU option. While looking into the matter, I did discover some
+work to provide CUDA support on non-NVidia GPUs, and some work with
+the library used by Whisper to port it to other GPUs, but have not
+spent much time looking into GPU support yet. I've so far used an old
+X220 laptop as my test machine, and only transcribed using its
+CPU.</p>
+
+<p>As it from a privacy standpoint is unthinkable to use computers
+under control of someone else (aka a "cloud" service) to transcribe
+ones thoughts and personal notes, I want to run the transcribing
+system locally on my own computers. The only sensible approach to me
+is to make the effort I put into this available for any Linux user and
+to upload the needed packages into Debian. Looking at Debian Bookworm, I
+discovered that only three packages were missing,
+<a href="https://bugs.debian.org/1034307">tiktoken</a>,
+<a href="https://bugs.debian.org/1034144">triton</a>, and
+<a href="https://bugs.debian.org/1034091">openai-whisper</a>. For a while
+I also believed
+<a href="https://bugs.debian.org/1034286">ffmpeg-python</a> was
+needed, but as its
+<a href="https://github.com/kkroening/ffmpeg-python/issues/760">upstream
+seem to have vanished</a> I found it safer
+<a href="https://github.com/openai/whisper/pull/1242">to rewrite
+whisper</a> to stop depending on in than to introduce ffmpeg-python
+into Debian. I decided to place these packages under the umbrella of
+<a href="https://salsa.debian.org/deeplearning-team">the Debian Deep
+Learning Team</a>, which seem like the best team to look after such
+packages. Discussing the topic within the group also made me aware
+that the triton package was already a future dependency of newer
+versions of the torch package being planned, and would be needed after
+Bookworm is released.</p>
+
+<p>All required code packages have been now waiting in
+<a href="https://ftp-master.debian.org/new.html">the Debian NEW
+queue</a> since Wednesday, heading for Debian Experimental until
+Bookworm is released. An unsolved issue is how to handle the neural
+network models used by Whisper. The default behaviour of Whisper is
+to require Internet connectivity and download the model requested to
+<tt>~/.cache/whisper/</tt> on first invocation. This obviously would
+fail <a href="https://people.debian.org/~bap/dfsg-faq.html">the
+deserted island test of free software</a> as the Debian packages would
+be unusable for someone stranded with only the Debian archive and solar
+powered computer on a deserted island.</p>
+
+<p>Because of this, I would love to include the models in the Debian
+mirror system. This is problematic, as the models are very large
+files, which would put a heavy strain on the Debian mirror
+infrastructure around the globe. The strain would be even higher if
+the models change often, which luckily as far as I can tell they do
+not. The small model, which according to its creator is most useful
+for English and in my experience is not doing a great job there
+either, is 462 MiB (deb is 414 MiB). The medium model, which to me
+seem to handle English speech fairly well is 1.5 GiB (deb is 1.3 GiB)
+and the large model is 2.9 GiB (deb is 2.6 GiB). I would assume
+everyone with enough resources would prefer to use the large model for
+highest quality. I believe the models themselves would have to go
+into the non-free part of the Debian archive, as they are not really
+including any useful source code for updating the models. The
+"source", aka the model training set, according to the creators
+consist of "680,000 hours of multilingual and multitask supervised
+data collected from the web", which to me reads material with both
+unknown copyright terms, unavailable to the general public. In other
+words, the source is not available according to the Debian Free
+Software Guidelines and the model should be considered non-free.</p>
+
+<p>I asked the Debian FTP masters for advice regarding uploading a
+model package on their IRC channel, and based on the feedback there it
+is still unclear to me if such package would be accepted into the
+archive. In any case I wrote build rules for a
+<a href="https://salsa.debian.org/deeplearning-team/openai-whisper-model">OpenAI
+Whisper model package</a> and
+<a href="https://github.com/openai/whisper/pull/1257">modified the
+Whisper code base</a> to prefer shared files under <tt>/usr/</tt> and
+<tt>/var/</tt> over user specific files in <tt>~/.cache/whisper/</tt>
+to be able to use these model packages, to prepare for such
+possibility. One solution might be to include only one of the models
+(small or medium, I guess) in the Debian archive, and ask people to
+download the others from the Internet. Not quite sure what to do
+here, and advice is most welcome (use the debian-ai mailing list).</p>
+
+<p>To make it easier to test the new packages while I wait for them to
+clear the NEW queue, I created an APT source targeting bookworm. I
+selected Bookworm instead of Bullseye, even though I know the latter
+would reach more users, is that some of the required dependencies are
+missing from Bullseye and I during this phase of testing did not want
+to backport a lot of packages just to get up and running.</p>
+
+<p>Here is a recipe to run as user root if you want to test OpenAI
+Whisper using Debian packages on your Debian Bookworm installation,
+first adding the APT repository GPG key to the list of trusted keys,
+then setting up the APT repository and finally installing the packages
+and one of the models:</p>
+<p><pre>
+curl https://geekbay.nuug.no/~pere/openai-whisper/D78F5C4796F353D211B119E28200D9B589641240.asc \
+ -o /etc/apt/trusted.gpg.d/pere-whisper.asc
+mkdir -p /etc/apt/sources.list.d
+cat > /etc/apt/sources.list.d/pere-whisper.list &lt;&lt;EOF
+deb https://geekbay.nuug.no/~pere/openai-whisper/ bookworm main
+deb-src https://geekbay.nuug.no/~pere/openai-whisper/ bookworm main
+EOF
+apt update
+apt install openai-whisper
+</pre></p>
+
+<p>The package work for me, but have not yet been tested on any other
+computer than my own. With it, I have been able to (badly) transcribe
+a 2 minute 40 second Norwegian audio clip to test using the small
+model. This took 11 minutes and around 2.2 GiB of RAM. Transcribing
+the same file with the medium model gave a accurate text in 77 minutes
+using around 5.2 GiB of RAM. My test machine had too little memory to
+test the large model, which I believe require 11 GiB of RAM. In
+short, this now work for me using Debian packages, and I hope it will
+for you and everyone else once the packages enter Debian.</p>
+
+<p>Now I can start on the audio recording part of this project.</p>

+ <description><p>Today I finally found time to track down a useful radio frequency
+scanner for my software defined radio. Just for fun I tried to locate
+the radios used in the areas, and a good start would be to scan all
+the frequencies to see what is in use. I've tried to find a useful
+program earlier, but ran out of time before I managed to find a useful
+tool. This time I was more successful, and after a few false leads I
+found a description of
+<a href="https://www.kali.org/tools/rtlsdr-scanner/">rtlsdr-scanner
+over at the Kali site</a>, and was able to track down
+<a href="https://gitlab.com/kalilinux/packages/rtlsdr-scanner.git">the
+Kali package git repository</a> to build a deb package for the
+scanner. Sadly the package is missing from the Debian project itself,
+at least in Debian Bullseye. Two runtime dependencies,
+<a href="https://gitlab.com/kalilinux/packages/python-visvis.git">python-visvis</a>
+and
+<a href="https://gitlab.com/kalilinux/packages/python-rtlsdr.git">python-rtlsdr</a>
+had to be built and installed separately. Luckily '<tt>gbp
+buildpackage</tt>' handled them just fine and no further packages had
+to be manually built. The end result worked out of the box after
+installation.</p>
+
+<p>My initial scans for FM channels worked just fine, so I knew the
+scanner was functioning. But when I tried to scan every frequency
+from 100 to 1000 MHz, the program stopped unexpectedly near the
+completion. After some debugging I discovered USB software radio I
+used rejected frequencies above 948 MHz, triggering a unreported
+exception breaking the scan. Changing the scan to end at 957 worked
+better. I similarly found the lower limit to be around 15, and ended

- <description><p>Just 15 days ago,
-<ahref="http://people.skolelinux.org/pere/blog/MIME_type__text_vnd_sosi__for_SOSI_map_data.html">I
-mentioned</a> my submission to IANA to register an official MIME type
-for the SOSI vector map format. This morning, just an hour ago, I was
-notified that
-<a href="https://www.iana.org/assignments/media-types/text/vnd.sosi">the
-MIME type "text/vnd.sosi"</a> is registered for this format. In
-addition to this registration, my
-<a href="https://github.com/file/file/blob/master/magic/Magdir/sosi">file(1)
-patch for a pattern matching rule for SOSI files</a> has been accepted
-into the official source of that program (pending a new release), and
-I've been told by the team behind
-<a href="https://www.nationalarchives.gov.uk/PRONOM/">PRONOM</a> that
-the SOSI format will be included in the next release of PRONOM, which
-they plan to release this summer around July.</p>

+ <description><p>Thanks to the efforts of the OpenSnitch lead developer Gustavo
+Iñiguez Goya allowing me to sponsor the upload,
+<a href="https://tracker.debian.org/pkg/opensnitch">the interactive
+application firewall OpenSnitch</a> is now available in Debian
+Testing, soon to become the next stable release of Debian.</p>
+
+<p>This is a package which set up a network firewall on one or more
+machines, which is controlled by a graphical user interface that will
+ask the user if a program should be allowed to connect to the local
+network or the Internet. If some background daemon is trying to dial
+home, it can be blocked from doing so with a simple mouse click, or by
+default simply by not doing anything when the GUI question dialog pop
+up. A list of all programs discovered using the network is provided
+in the GUI, giving the user an overview of how the machine(s) programs
+use the network.</p>
+
+<p>OpenSnitch was uploaded for NEW processing about a month ago, and I
+had little hope of it getting accepted and shaping up in time for the
+package freeze, but the Debian ftpmasters proved to be amazingly quick
+at checking out the package and it was accepted into the archive about
+week after the first upload. It is now team maintained under the Go
+language team umbrella. A few fixes to the default setup is only in
+Sid, and should migrate to Testing/Bookworm in a week.</p>
+
+<p>During testing I ran into an
+<a href="https://github.com/evilsocket/opensnitch/issues/813">issue
+with Minecraft server broadcasts disappearing</a>, which was quickly
+resolved by the developer with a patch and a proposed configuration
+change. I've been told this was caused by the Debian packages default
+use if /proc/ information to track down kernel status, instead of the
+newer eBPF module that can be used. The reason is simply that
+upstream and I have failed to find a way to build the eBPF modules for
+OpenSnitch without a complete configured Linux kernel source tree,
+which as far as we can tell is unavailable as a build dependency in
+Debian. We tried unsuccessfully so far to use the kernel-headers
+package. It would be great if someone could provide some clues how to
+build eBPF modules on build daemons in Debian, possibly without the full
+kernel source.</p>
