+ <description><p>Like før julaften ble en artikkel jeg har skrevet om vedlikehold av
+<a href="https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard">Noark
+5 Tjenestegrensesnitt</a> og Nikita publisert i <a
+href="https://www.arkivrad.no/arkivrad">tidsskriftet Arkivråd</a>.
+Det er basert på
+<a href="http://people.skolelinux.org/pere/blog/_pen_og_gjennomsiktig_vedlikehold_av_spesifikasjonen_for_Noark_5_Tjenestegrensesnitt.html">min bloggpost
+om samme tema</a> som ble publisert 2019-03-11. Jeg oppdaget nettopp
+at nettsiden til tidsskriftet Arkivråd er oppdatert med siste utgave,
+og artikkelen dermed er tilgjengelig for alle. Du finner den i
+<a href="https://www.arkivrad.no/sites/arkivrad/files/arkivrad_03_2019_nett.pdf">PDF-en
+til nummer 2019/3 på side 30-33</a>. Jeg håper leserne av
+tidsskriftet får lyst til å sjekke ut tjenestegrensesnittet og at
+artikkelen vil gjøre det enklere for flere å bidra til en enda bedre,
+klarere og mer entydig API-spesifikasjon. Det kan gjøre at
+<a href="https://gitlab.com/OsloMet-ABI/nikita-noark5-core/">arkivsystemet
+Nikita</a> kan bli enda bedre når spesifikasjonen forbedres.</p>

- <title>Jami/Ring, finally functioning peer to peer communication client</title>

- <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>
