- <description><p>Childs need to learn how to guard their privacy too. To help them,
-<a href="https://edri.org/">European Digital Rights (EDRi)</a> created
-a colorful booklet providing information on several privacy related topics,
-and tips on how to protect ones privacy in the digital age.</p>
-
-<p>The 24 page booklet titled Digital Defenders is
-<a href="https://edri.org/digital-defenders-help-kids-defend-their-privacy-around-europe">available
-in several languages</a>. Thanks to the valuable contributions from
-members of <a href="https://efn.no/">the Electronic Foundation Norway
-(EFN)</a> and others, it is also available in Norwegian Bokmål.
-If you would like to have it available in your language too,
-<a href="https://hosted.weblate.org/projects/efn/privacy4kids/">contribute
-via Weblate</a> and get in touch.</p>
-
-<p>But a funny, well written and good looking PDF do not have much
-impact, unless it is read by the right audience. To increase the
-chance of kids reading it, I am currently assisting EFN in getting
-copies printed on paper to distribute on the street and in class
-rooms. Print the booklet was made possible thanks to a small et of
-great sponsors. Thank you very much to each and every one of them! I
-hope to have the printed booklet ready to hand out on Tuesday, when
-<a href="https://www.nuug.no/>">the Norwegian Unix Users Group</a> is
-organizing <a href="https://wiki.nuug.no/sommerfest2019">its yearly
-barbecue for geeks and free software zealots in the Oslo area</a>. If
-you are nearby, feel free to come by and check out the party and the
-booklet.</p>
-
-<p>If the booklet proves to be a success, it would be great to get
-more sponsoring and distribute it to every kid in the country. :)</p>

- <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>

+ <description><p>I am very pleased to be able to share with you
+<a href="https://lists.nuug.no/pipermail/nikita-noark/2021-June/000576.html">the
+announcement of a new version of the archiving system Nikita</a>
+published by its lead developer Thomas Sødring:</p>
<p><blockquote>
-.../sakarkiv/journalpost?filter=contains(tittel, 'nabovarsel')
+
+<p>It is with great pleasure that we can announce a new release of
+nikita. Version 0.6
+(<a href="https://gitlab.com/OsloMet-ABI/nikita-noark5-core">https://gitlab.com/OsloMet-ABI/nikita-noark5-core</a>). This
+release makes new record keeping functionality available. This really
+is a maturity release. Both in terms of functionality but also code.
+Considerable effort has gone into refactoring the codebase and
+simplifying the code. Notable changes for this release include:</p>
+
+<ul>
+
+ <li>Significantly improved OData parsing</li>
+ <li>Support for business specific metadata and national identifiers</li>
+ <li>Continued implementation of domain model and endpoints</li>
+ <li>Improved testing</li>
+ <li>Ability to export and import from arkivstruktur.xml</li>
+
+</ul>
+
+<p>We are currently in the process of reaching an agreement with an
+archive institution to publish their picture archive using nikita with
+business specific metadata and we hope that we can share this with you
+soon. This is an interesting project as it allows the organisation to
+bring an older picture archive back to life while using the original
+metadata values stored as business specific metadata. Combined with
+OData means the scope and use of the archive is significantly
+increased and will showcase both the flexibility and power of
+Noark.</p>
+
+<p>I really think we are approaching a version 1.0 of nikita, even
+though there is still a lot of work to be done. The notable work at
+the moment is to implement access-control and full text indexing of
+documents.</p>
+
+<p>My sincere thanks to everyone who has contributed to this
+release!</p>
+
+<p>- Thomas</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.

-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>Yesterday morning I got a warning call from the Debian quality
+control system that
+<a href="https://tracker.debian.org/pkg/vlc-plugin-bittorrent">the VLC
+bittorrent plugin</a> was due to be removed because of a release
+critical bug in one of its dependencies. As you might remember, this
+plugin make VLC able to stream videos directly from a bittorrent
+source using both torrent files and magnet links, similar to using a
+HTTP source. I believe such protocol support is a vital feature in
+VLC, allowing efficient streaming from sources such at the almost 7
+million movies in <a href="https://archive.org/">the Internet
+Archive</a>.</p>
+
+<p>The dependency was the unmaintained
+<a href="https://tracker.debian.org/pkg/libtorrent-rasterbar">libtorrent-rasterbar</a>
+package, and <a href="https://bugs.debian.org/987306">the bug in
+question</a> blocked its python library from working properly. As I
+did not want Bullseye to release without bittorrent support in VLC, I
+set out to check out the status, and track down a fix for the problem.
+Luckily the issue had already been identified and fixed upstream,
+providing everything needed. All I needed to do was to fetch the
+Debian git repository, extract and trim the patch from upstream and
+apply it to the Debian package for upload.</p>
+
+<p>The fixed library was uploaded yesterday evening. But that is not
+enough to get it into Bullseye, as Debian is currently in package
+freeze to prepare for a new next stable release. Only non-critical
+packages with
+<a href="https://wiki.debian.org/ContinuousIntegration/autopkgtest">autopkgtest
+setup</a> included, in other words able to validate automatically that
+the package is working, are allowed to migrate automatically into the
+next release at this stage. And the unmaintained libtorrent-rasterbar
+lack such testing, and thus needed a manual override. I am happy to
+report that such manual override was approved a few minutes ago, thus
+increasing significantly the chance of VLC bittorrent streaming being
+available out of the box also for Debian/Buster users. A bit too
+close shave for my liking, as the Bullseye release is most likely just
+a few days away, and this did feel like the package was saved by the
+bell. I am so glad the warning email showed up in time for me to
+handle the issue, and a big thanks go to the Debian Release team for
+the quick feedback on
+<a href="irc://irc.debian.org/%23debian-release">#debian-release</a>
+and their <a href="https://bugs.debian.org/987865">swift
+unblocking</a>.</p>

- <description><p>The first book I published,
-<a href="http://www.free-culture.cc/">Free Culture by Lawrence
-Lessig</a>, is still selling a few copies. Not a lot, but enough to
-have contributed slightly over $500 to the <a
-href="https://creativecommons.org/">Creative Commons Corporation</a>
-so far. All the profit is sent there. Most books are still sold via
-Amazon (83 copies), with Ingram second (49) and Lulu (12) and Machette (7) as
-minor channels. Bying directly from Lulu bring the largest cut to
-Creative Commons. The English Edition sold 80 copies so far, the
-French 59 copies, and Norwegian only 8 copies. Nothing impressive,
-but nice to see the work we put down is still being appreciated. The

+from the newcomer Norwegian Bitcoin Exchange.</p>
+
+<p>I also decided to migrate the project from github to gitlab in the

+ <description><p>Etter intenst arbeid over mange måneder er endelig den norske
+utgaven av «Hvordan knuse overvåkningskapitalismen» av Cory Doctorow
+ferdig og klar til å glede millioner av lesere over hele verden.
+Følgende pressemelding ble nettopp sendt ut til norske redaksjoner:
+
+<blockquote>
+
+<p><strong>Hva gjør stordata med oss, og hvordan gjør algoritmene
+«fake news» til realiter?</strong></p>
+
+<p>Nå foreligger en viktig bok om temaet også på norsk. Boken klargjør
+og foreslår hvordan vi selv som enkeltpersoner, men også nasjonalt og
+internasjonalt kan bekjempe stordatakonsentrasjonene;
+«overvåkingskapitalismen». Boken er «Hvordan knuse
+overvåkingskapitalismen» av dr. Cory Doctorow. Den engelske
+bokutgivelsen kom for noen dager siden og lanseres med et Webinar
+torsdag 2021-01-28. Doctorow besøkte Norge og NUUG i desember med sin
+presentasjon Monopoly, Not Mind Control: What's Really Happening With
+"Surveillance Capitalism".</p>
+
+<p>I funn etter funn, eksempel etter eksempel, gjennomgår og
+analyserer dr. Doctorow de utfordringer vi møter i større og større
+omfang. Ikke bare i USA, men også her hjemme.</p>
+
+<p>Cory Doctorow er en britisk-kanadisk forfatter, journalist og
+aktivist, kjent for sine science fiction-romaner, for arbeidet for
+Creative Commons-bevegelsen, og for sine bidrag til reform av
+opphavsretten. Han er både æresdoktor og gjesteforeleser i
+datavitenskap ved Open University i UK, konsulent for Electronic
+Frontier Foundation, og godt kjent for innsiktsfullt å kommentere og
+skrive om digital utvikling.</p>
+
+<p>Boken lanseres nå på norsk, både som ebok og på papir, oversatt av
+en dugnadsgjeng ledet av Petter Reinholdtsen.</p>
+
+<p>Boken reiser noen helt grunnleggende og samfunnskritiske spørsmål:
+Hva fører det til når store deler av Internettet domineres av få store
+aktører og deres styringsverktøy og algoritmer?</p>
+
+<p>Som individer bør vi være opptatt at grenser blir satt og håndhevet
+- grenser for overvåkning av individet, for utøvelse av kommersiell
+og politisk påvirkning, og for monopoldannelser i
+dataverdenen. Slik grensesetting styrker personvernet.</p>
+
+<p>Konkurransetilsynet har ansvaret for at konkurranselovens § 11 skal
+forby «et dominerende foretak for utilbørlig å utnytte og misbruke
+sin dominerende stilling». Et tilsvarende forbud omfattes også av
+EØS-avtalens artikkel 54. Boken går i detalj om serien av
+innskrenkninger vi møter i valgfriheten, innskrenkninger som denne
+lovgivningen nettopp skal forhindre. Håndhevelse av en slik lovgivning
+er også til fordel for mindre næringsdrivende som uten dette får
+begrenset sine faktiske eller potensielle muligheter for vekst og
+etablering. «Slik atferd kan utgjøre et misbruk og kan ta ulike
+former», skriver Konkurransetilsynet.</p>
+
+<p>Cory Doctorow går i sin bok lengre enn det med sine mange eksempler
+på forhold det burde vært grepet inn mot.</p>
+
+<p>«Boken bør bidra til et sterkere engasjemen fra voktere av
+Internettet nasjonalt og internasjonalt - EU medregnet» sier
+oversetter Ole-Erik Yrvin og fortsetter: «Vi har derfor
+<a href="http://people.skolelinux.org/pere/blog/images/2021-01-26-knus-overvaakningskapitalismen-helleland.pdf">allerede
+tatt opp bokens forslag</a> direkte med Distrikts- og
+digitaliseringsminister Linda Hofstad Helleland (H) og
+Konkurransetilsynet slik at de kan følges opp.»</p>
+
+<p>«Også Norge bør innta en pådriverrolle i denne utviklingen», sier
+Petter Reinholdtsen. «Tiden er knapp, og tilsynsmyndighetene må få
+de verktøy og de ressurser de trenger for at vi her hjemme skal oppnå
+nødvendige resultater. Dette gjelder ikke bare vår egen generasjon;
+det gjelder alle generasjoner fremover», avslutter Petter
+Reinholdsen.</p>

- <description><p>A while back a college and friend from Debian and the Skolelinux /
-Debian Edu project approached me, asking if I knew someone that might
-be interested in helping out with a technology project he was running
-as a teacher at <a href="https://www.ecolefrancodanoise.dk/">L'école
-franco-danoise</a> - the Danish-French school and kindergarden. The
-kids were building robots, rovers. The story behind it is to build a
-rover for use
-<a href="http://blog.ecolefrancodanoise.dk/first-week-on-the-dark-side">on
-the dark side of the moon</a>, and remote control it. As travel cost
-was a bit high for the final destination, and they wanted to test the
-concept first, he was looking for volunteers to host a rover for the
-kids to control in a foreign country. I ended up volunteering as a
-host, and last week the rover arrived. It took a while to arrive
-after <a href="http://blog.ecolefrancodanoise.dk/model-moms">it was
-built and shipped</a>, because of customs confusion. Luckily we were
-able fix it quickly with help from my colleges at work.</p>
-
-<p>This is what it looked like when the rover arrived. Note the cute
-eyes looking up on me from the wrapping</p>
-

-
-<p style="text-align:left">Once the robot arrived, we needed to track
-down batteries and figure out how to build custom firmware for it with
-the appropriate wifi settings. I asked a friend if I could get two
-18650 batteries from his pile of Tesla batteries (he had them from the
-wrack of a crashed Tesla), so now the rover is running on Tesla
-batteries.</p>
-
-<p>Building
-<a href="https://gitlab.com/ecolefrancodanoise/arduino-efd/">the rover
-firmware</a> proved a bit harder, as the code did not work out of the
-box with the Arduino IDE package in Debian Buster. I suspect this is
-due to a unsolved
-<a href="https://github.com/arduino/Arduino/pull/2703"> license problem
-with arduino</a> blocking Debian from upgrading to the latest version.
-In the end we gave up debugging why the IDE failed to find the
-required libraries, and ended up using the Arduino Makefile from the
-<a href="https://tracker.debian.org/pkg/arduino-mk">arduino-mk Debian
-package</a> instead. Unfortunately the camera library is missing from
-the Arduino environment in Debian, so we disabled the camera support
-for the first firmware build, to get something up and running. With
-this reduced firmware, the robot could be controlled via the
-controller server, driving around and measuring distance using its
-internal acoustic sensor.</p>
-
-<p>Next, With some help from my friend in Denmark, which checked in the
-camera library into the gitlab repository for me to use, we were able
-to build a new and more complete version of the firmware, and the
-robot is now up and running. This is what the "commander" web page
-look like after taking a measurement and a snapshot:</p>

+ <description><p>After a lot of hard work by its maintainer Alexandre Viau and
+others, the decentralized communication platform
+<a href="https://en.wikipedia.org/wiki/Jami_(software)">Jami</a>
+(earlier known as Ring), managed to get
+<a href="https://tracker.debian.org/pkg/ring">its latest version</a>
+into Debian Testing. Several of its dependencies has caused build and
+propagation problems, which all seem to be solved now.</p>
+
+<p>In addition to the fact that Jami is decentralized, similar to how
+bittorrent is decentralized, I first of all like how it is not
+connected to external IDs like phone numbers. This allow me to set up
+computers to send me notifications using Jami without having to find
+get a phone number for each computer. Automatic notification via Jami
+is also made trivial thanks to the provided client side API (as a DBus
+service). Here is my bourne shell script demonstrating how to let any
+system send a message to any Jami address. It will create a new
+identity before sending the message, if no Jami identity exist
+already:</p>

+<p>«Gjort med Creative Commons» er en bok om gjenbruk, deling og den
+digitale allmenningen. Boken omhandler å bygge en forretningsmodell på
+åpne verdier, endringene i tankesett og filosofi, og fordelene og
+praksisen som kommer med å være «åpen».</p>
+<p>Forfatterne Paul Stacey og Sarah Hinchliff Pearson tar oss med inn
+i samtaler med 24 mennesker, prosjekter og organisasjoner som på ulike
+måter generere inntekter gjennom deling av sine verk. Som leser får
+man innsikt i hvordan alt fra forskere, forfattere, kunstnere og
+filmskapere tjener penger basert på åpne forretningsmodeller. En av
+referansestudiene i denne boken viser hvordan Blender Animation Studio
+lager vakre animasjonsfilmer som de publiserer under en fri lisens,
+basert på en plattform som er fri programvare.</p>
+
+<p>Utover praktiske eksempler på forskjellige forretningsmodeller berører
+også boken forskjellen mellom tradisjonelle kommersielle virksomheter og
+de som tar utgangspunkt i den globale delingskulturen.</p>
+
+<p>«Hvis du ønsker å lære mer om digital delingskultur og Creative Commons
+er dette en bok som både vil inspirere og gi grunnleggende innsikt» sier
+leder av Creative Commons Norge, Christer Solheim Gundersen. «De siste
+årene har denne globale bevegelsen sett en betydelig vekst med totalt
+over 1,6 milliarder verk med CC-lisens tilgjengelig på nett.»
+
+Nå er den tilgjengelig på norsk takket være liten gruppe frivillige
+entusiaster ledet av Petter Reinholdtsen. «På vegne av Creative Commons
+Norge vil jeg takke hver enkelt bidragsyter. Dette prosjektet er i seg
+selv et inspirerende eksempel på at delingskulturen også har godt
+fotfeste her i Norge.», avslutter Gundersen.</p>
+
+<p>Boken er selvsagt fritt tilgjengelig under en Creative Commons lisens,
+og kan også kjøpes som ebok og papirutgave på blant annet Lulu.com og
+Amazon.</p>

+
+<p>I am happy to report that we finally made it! Norwegian Bokmål
+became the first translation published on paper of the new Buster
+based edition of "<a href="https://debian-handbook.info/">The Debian
+Administrator's Handbook</a>". The print proof reading copy arrived
+some days ago, and it looked good, so now the book is approved for
+general distribution. This updated paperback edition <a
+href="https://debian-handbook.info/get/#norwegian">is available from
+lulu.com</a>. The book is also available for download in electronic
+form as PDF, EPUB and Mobipocket, and can also be
+<a href="https://debian-handbook.info/browse/nb-NO/stable/">read online</a>.</p>
+
+<p>I am very happy to wrap up this Creative Common licensed project,
+which concludes several months of work by several volunteers. The
+number of Linux related books published in Norwegian are few, and I
+really hope this one will gain many readers, as it is packed with deep
+knowledge on Linux and the Debian ecosystem. The book will be
+available for various Internet book stores like Amazon and Barnes &
+Noble soon, but I recommend buying
+"<a href="https://www.lulu.com/en/us/shop/roland-mas-and-rapha%C3%ABl-hertzog/h%C3%A5ndbok-for-debian-administratoren/paperback/product-9j7qwq.html">Håndbok

- <description><p>As part of my involvement in the work to
-<a href="https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard">standardise
-a REST based API for Noark 5</a>, the Norwegian archiving standard, I
-spent some time the last few months to try to register a
-<a href="https://www.iana.org/assignments/media-types/">MIME type</a>
-and <a href="https://www.nationalarchives.gov.uk/PRONOM/">PRONOM
-code</a> for the SOSI file format. The background is that there is a
-set of formats approved for long term storage and archiving in Norway,
-and among these formats, SOSI is the only format missing a MIME type
-and PRONOM code.</p>
-
-<p>What is SOSI, you might ask? To quote Wikipedia: SOSI is short for
-Samordnet Opplegg for Stedfestet Informasjon (literally "Coordinated
-Approach for Spatial Information", but more commonly expanded in
-English to Systematic Organization of Spatial Information). It is a
-text based file format for geo-spatial vector information used in
-Norway. Information about the SOSI format can be found in English
-from <a href="https://en.wikipedia.org/wiki/SOSI">Wikipedia</a>. The
-specification is available in Norwegian from
-<a href="https://www.kartverket.no/geodataarbeid/Standarder/SOSI/">the
-Norwegian mapping authority</a>. The SOSI standard, which originated
-in the beginning of nineteen eighties, was the inspiration and formed the
-basis for the XML based
-<a href="https://en.wikipedia.org/wiki/Geography_Markup_Language">Geography
-Markup Language</a>.</p>
-
-<p>I have so far written
-<a href="https://github.com/file/file/pull/67">a pattern matching
-rule</a> for the file(1) unix tool to recognize SOSI files, submitted
-a request to the PRONOM project to have a PRONOM ID assigned to the
-format (reference TNA1555078202S60), and today send a request to IANA
-to register the "text/vnd.sosi" MIME type for this format (referanse
-<a href="https://tools.iana.org/public-view/viewticket/1143144">IANA
-#1143144</a>). If all goes well, in a few months, anyone implementing
-the Noark 5 Tjenestegrensesnitt API spesification should be able to
-use an official MIME type and PRONOM code for SOSI files. In
-addition, anyone using SOSI files on Linux should be able to
-automatically recognise the format and web sites handing out SOSI
-files can begin providing a more specific MIME type. So far, SOSI
-files has been handed out from web sites using the
-"application/octet-stream" MIME type, which is just a nice way of
-stating "I do not know". Soon, we will know. :)</p>

- <title>PlantUML for text based UML diagram modelling - nice free software</title>
- <link>http://people.skolelinux.org/pere/blog/PlantUML_for_text_based_UML_diagram_modelling___nice_free_software.html</link>
- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/PlantUML_for_text_based_UML_diagram_modelling___nice_free_software.html</guid>
- <pubDate>Mon, 25 Mar 2019 09:35:00 +0100</pubDate>
- <description><p>As part of my involvement with the
-<a href="https://gitlab.com/OsloMet-ABI/nikita-noark5-core/">Nikita
-Noark 5 core project</a>, I have been proposing improvements to the
-API specification created by <a href="https://www.arkivverket.no/">The
-National Archives of Norway</a> and helped migrating the text from a
-version control system unfriendly binary format (docx) to Markdown in
-git. Combined with the migration to a public git repository (on
-github), this has made it possible for anyone to suggest improvement
-to the text.</p>
-
-<p>The specification is filled with UML diagrams. I believe the
-original diagrams were modelled using Sparx Systems Enterprise
-Architect, and exported as EMF files for import into docx. This
-approach make it very hard to track changes using a version control
-system. To improve the situation I have been looking for a good text
-based UML format with associated command line free software tools on
-Linux and Windows, to allow anyone to send in corrections to the UML
-diagrams in the specification. The tool must be text based to work
-with git, and command line to be able to run it automatically to
-generate the diagram images. Finally, it must be free software to
-allow anyone, even those that can not accept a non-free software
-license, to contribute.</p>
-
-<p>I did not know much about free software UML modelling tools when I
-started. I have used dia and inkscape for simple modelling in the
-past, but neither are available on Windows, as far as I could tell. I
-came across a nice
-<a href="https://modeling-languages.com/text-uml-tools-complete-list/">list
-of text mode uml tools</a>, and tested out a few of the tools listed
-there. <a href="http://plantuml.com/">The PlantUML tool</a> seemed
-most promising. After verifying that the packages
-<a href="https://tracker.debian.org/pkg/plantuml">is available in
-Debian</a> and found <a href="https://github.com/plantuml/plantuml">its
-Java source</a> under a GPL license on github, I set out to test if it
-could represent the diagrams we needed, ie the ones currently in
-<a href="https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/">the
-Noark 5 Tjenestegrensesnitt specification</a>. I am happy to report
-that it could represent them, even thought it have a few warts here
-and there.</p>
-
-<p>After a few days of modelling I completed the task this weekend. A
-temporary link to the complete set of diagrams (original and from
-PlantUML) is available in
-<a href="https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/issues/76">the
-github issue discussing the need for a text based UML format</a>, but
-please note I lack a sensible tool to convert EMF files to PNGs, so
-the "original" rendering is not as good as the original was in the
-publised PDF.</p>
-
-<p>Here is an example UML diagram, showing the core classes for
-keeping metadata about archived documents:</p>

-<tt>media/uml-class-arkivskaper.iuml<tt>:</p>
-
-<pre>
-@startuml
-class Arkivstruktur.Arkivskaper <Arkivenhet> {
- +arkivskaperID : string
- +arkivskaperNavn : string
- +beskrivelse : string [0..1]
-}
-@enduml
-</pre>
-
-<p>This is what the complete diagram for the PlantUML notation above
-look like:</p>
-
-<p><img width="80%" src="http://people.skolelinux.org/pere/blog/images/2019-03-25-noark5-plantuml-diagrameksempel.png"></p>
-
-<p>A cool feature of PlantUML is that the generated PNG files include
-the entire original source diagram as text. The source (with include
-statements expanded) can be extracted using for example
-<tt>exiftool</tt>. Another cool feature is that parts of the entities
-can be hidden after inclusion. This allow to use include files with
-all attributes listed, even for UML diagrams that should not list any
-attributes.</p>
-
-<p>The diagram also show some of the warts. Some times the layout
-engine place text labels on top of each other, and some times it place
-the class boxes too close to each other, not leaving room for the
-labels on the relationship arrows. The former can be worked around by
-placing extra newlines in the labes (ie "\n"). I did not do it here
-to be able to demonstrate the issue. I have not found a good way
-around the latter, so I normally try to reduce the problem by changing
-from vertical to horizontal links to improve the layout.</p>
-
-<p>All in all, I am quite happy with PlantUML, and very impressed with
-how quickly its lead developer responds to questions. So far I got an
-answer to my questions in a few hours when I send an email. I
-definitely recommend looking at PlantUML if you need to make UML
-diagrams. Note, PlantUML can draw a lot more than class relations.

+ <description><p>Three years ago, the first Norwegian Bokmål edition of
+"<a href="https://debian-handbook.info/">The Debian Administrator's
+Handbook</a>" was published. This was based on Debian Jessie. Now a
+new and updated version based on Buster is getting ready. Work on the
+updated Norwegian Bokmål edition has been going on for a few months
+now, and yesterday, we reached the first mile stone, with 100% of the
+texts being translated. A lot of proof reading remains, of course,
+but a major step towards a new edition has been taken.</p>
+
+<p>The book is translated by volunteers, and we would love to get some
+help with the proof reading. The translation uses
+<a href="https://hosted.weblate.org/languages/nb_NO/debian-handbook/">the
+hosted Weblate service</a>, and we welcome everyone to have a look and
+submit improvements and suggestions. There is also a proof readers
+PDF available on request, get in touch if you want to help out that
+way.</p>

- <description><p>Yesterday, a new release of
-<a href="https://gitlab.com/OsloMet-ABI/nikita-noark5-core/">Nikita
-Noark 5 core project</a> was
-<a href="https://lists.nuug.no/pipermail/nikita-noark/2019-March/000451.html">announced
-on the project mailing list</a>. The free software solution is an
-implementation of the Norwegian archive standard Noark 5 used by
-government offices in Norway. These were the changes in version 0.3
-since version 0.2.1 (from NEWS.md):</p>
-
-<ul>
- <li>Improved ClassificationSystem and Class behaviour.</li>
- <li>Tidied up known inconsistencies between domain model and hateaos links.</li>
- <li>Added experimental code for blockchain integration. </li>
- <li>Make token expiry time configurable at upstart from properties file.</li>
- <li>Continued work on OData search syntax.</li>
- <li>Started work on pagination for entities, partly implemented for Saksmappe.</li>
- <li>Finalise ClassifiedCode Metadata entity.</li>
- <li>Implement mechanism to check if authentication token is still
- valid. This allow the GUI to return a more sensible message to the
- user if the token is expired.</li>
- <li>Reintroduce browse.html page to allow user to browse JSON API using
- hateoas links.</li>
- <li>Fix bug in handling file/mappe sequence number. Year change was
- not properly handled.</li>
- <li>Update application yml files to be in sync with current development.</li>
- <li>Stop 'converting' everything to PDF using libreoffice. Only
- convert the file formats doc, ppt, xls, docx, pptx, xlsx, odt, odp
- and ods.</li>
- <li>Continued code style fixing, making code more readable.</li>
- <li>Minor bug fixes.</li>
-
-</ul>

+ <description><p>As a member of the <a href="https://www.nuug.no/">Norwegian Unix
+User Group</a>, I have the pleasure of receiving the
+<a href="https://www.usenix.org/">USENIX</a> magazine
+<a href="https://www.usenix.org/publications/login/">;login:</a>
+several times a year. I rarely have time to read all the articles,
+but try to at least skim through them all as there is a lot of nice
+knowledge passed on there. I even carry the latest issue with me most
+of the time to try to get through all the articles when I have a few
+spare minutes.</p>
+
+<p>The other day I came across a nice article titled
+"<a href="https://www.usenix.org/publications/login/winter2018/oneill">The
+Secure Socket API: TLS as an Operating System Service</a>" with a
+marvellous idea I hope can make it all the way into the POSIX standard.
+The idea is as simple as it is powerful. By introducing a new
+socket() option IPPROTO_TLS to use TLS, and a system wide service to
+handle setting up TLS connections, one both make it trivial to add TLS
+support to any program currently using the POSIX socket API, and gain
+system wide control over certificates, TLS versions and encryption
+systems used. Instead of doing this:</p>
+
+<p><blockquote><pre>
+int socket = socket(PF_INET, SOCK_STREAM, IPPROTO_TCP);
+</pre></blockquote></p>
+
+<p>the program code would be doing this:<p>
+
+<p><blockquote><pre>
+int socket = socket(PF_INET, SOCK_STREAM, IPPROTO_TLS);
+</pre></blockquote></p>
+
+<p>According to the ;login: article, converting a C program to use TLS
+would normally modify only 5-10 lines in the code, which is amazing
+when compared to using for example the OpenSSL API.</p>
+
+<p>The project has set up the
+<a href="https://securesocketapi.org/">https://securesocketapi.org/</a>
+web site to spread the idea, and the code for a kernel module and the
+associated system daemon is available from two github repositories:
+<a href="https://github.com/markoneill/ssa">ssa</a> and
+<a href="https://github.com/markoneill/ssa-daemon">ssa-daemon</a>.
+Unfortunately there is no explicit license information with the code,
+so its copyright status is unclear. A
+<a href="https://github.com/markoneill/ssa/issues/2">request to solve
+this</a> about it has been unsolved since 2018-08-17.</p>
+
+<p>I love the idea of extending socket() to gain TLS support, and
+understand why it is an advantage to implement this as a kernel module
+and system wide service daemon, but can not help to think that it
+would be a lot easier to get projects to move to this way of setting
+up TLS if it was done with a user space approach where programs
+wanting to use this API approach could just link with a wrapper
+library.</p>
+
+<p>I recommend you check out this simple and powerful approach to more
+secure network connections. :)</p>
