-               <description>&lt;p&gt;I have  earlier covered the basics of trusted timestamping using the
-&#39;openssl ts&#39; client.  See blog post for
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Public_Trusted_Timestamping_services_for_everyone.html&quot;&gt;2014&lt;/a&gt;,
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/syslog_trusted_timestamp___chain_of_trusted_timestamps_for_your_syslog.html&quot;&gt;2016&lt;/a&gt;
-and
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Idea_for_storing_trusted_timestamps_in_a_Noark_5_archive.html&quot;&gt;2017&lt;/a&gt;
-for those stories.  But some times I want to integrate the timestamping
-in other code, and recently I needed to integrate it into Python.
-After searching a bit, I found
-&lt;a href=&quot;https://dev.entrouvert.org/projects/python-rfc3161&quot;&gt;the
-rfc3161 library&lt;/a&gt; which seemed like a good fit, but I soon
-discovered it only worked for python version 2, and I needed something
-that work with python version 3.  Luckily I next came across
-&lt;a href=&quot;https://github.com/trbs/rfc3161ng/&quot;&gt;the rfc3161ng library&lt;/a&gt;,
-a fork of the original rfc3161 library.  Not only is it working with
-python 3, it have fixed a few of the bugs in the original library, and
-it has an active maintainer.  I decided to wrap it up and make it
-&lt;a href=&quot;https://tracker.debian.org/pkg/python-rfc3161ng&quot;&gt;available in
-Debian&lt;/a&gt;, and a few days ago it entered Debian unstable and testing.&lt;/p&gt;
-
-&lt;p&gt;Using the library is fairly straight forward.  The only slightly
-problematic step is to fetch the required certificates to verify the
-timestamp.  For some services it is straight forward, while for others
-I have not yet figured out how to do it.  Here is a small standalone
-code example based on of the integration tests in the library code:&lt;/p&gt;
-
-&lt;pre&gt;
-#!/usr/bin/python3
-
-&quot;&quot;&quot;
-
-Python 3 script demonstrating how to use the rfc3161ng module to
-get trusted timestamps.
-
-The license of this code is the same as the license of the rfc3161ng
-library, ie MIT/BSD.
-
-&quot;&quot;&quot;

-import os
-import pyasn1.codec.der
-import rfc3161ng

-    f.write(data)
-    f.flush()
-    f.seek(0)
-
-def fetch(url, f=None):
-    response = urllib.request.urlopen(url)
-    data = response.read()
-    if f:
-        store(f, data)
-    return data
-
-def main():
-    with tempfile.NamedTemporaryFile() as cert_f,\
-        tempfile.NamedTemporaryFile() as ca_f,\
-        tempfile.NamedTemporaryFile() as msg_f,\
-        tempfile.NamedTemporaryFile() as tsr_f:
-
-        # First fetch certificates used by service
-        certificate_data = fetch(&#39;https://freetsa.org/files/tsa.crt&#39;, cert_f)
-        ca_data_data = fetch(&#39;https://freetsa.org/files/cacert.pem&#39;, ca_f)
-
-        # Then timestamp the message
-        timestamper = \
-            rfc3161ng.RemoteTimestamper(&#39;http://freetsa.org/tsr&#39;,
-                                        certificate=certificate_data)
-        data = b&quot;Python forever!\n&quot;
-        tsr = timestamper(data=data, return_tsr=True)
-
-        # Finally, convert message and response to something &#39;openssl ts&#39; can verify
-        store(msg_f, data)
-        store(tsr_f, pyasn1.codec.der.encoder.encode(tsr))
-        args = [&quot;openssl&quot;, &quot;ts&quot;, &quot;-verify&quot;,
-                &quot;-data&quot;, msg_f.name,
-               &quot;-in&quot;, tsr_f.name,
-               &quot;-CAfile&quot;, ca_f.name,
-                &quot;-untrusted&quot;, cert_f.name]
-        subprocess.check_call(args)
-
-if &#39;__main__&#39; == __name__:
-   main()
-&lt;/pre&gt;
-
-&lt;p&gt;The code fetches the required certificates, store them as temporary
-files, timestamp a simple message, store the message and timestamp to
-disk and ask &#39;openssl ts&#39; to verify the timestamp.  A timestamp is
-around 1.5 kiB in size, and should be fairly easy to store for future
-use.&lt;/p&gt;

+               <description>&lt;p&gt;Det er tett med sensorstasjoner langs veinettet i Norge, som
+registrerer hvilke kjøretøy som passerer eller tar bilde av de som
+drar forbi.  I følge
+&lt;a href=&quot;https://vegkart.atlas.vegvesen.no/&quot;&gt;Vegvesenets nasjonale
+veidatabank (NVDB)&lt;/a&gt;, er det 353 bomstasjoner langs det norske
+veinettet.  21 i nordnorge, 48 i trøndelagsområdet, 13 på
+nordvestlandet, 91 i bergenstraktene og 180 på østlandsområdet.  I
+tillegg finnes det et utall overvåkningskamera og noen titalls
+RFID-avlesere for bompengebrikker som samler inn informasjon om hvilke
+biler som befinner seg hvor i landet.  For ikke å glemme alle
+mobilbasestasjoner som registrerer hvor brukere av mobilnettverket
+befinner seg.  De er ikke tema i dag.&lt;/p&gt;
+
+&lt;p&gt;De som kjører mye har interesse av å vite hvor mye bompenger det vil
+koste å kjøre fra et sted til et annet, og dette behovet har aktørene
+bak &lt;a href=&quot;https://bompengekalkulator.no/&quot;&gt;Bompengekalkulatoren&lt;/a&gt;
+tatt sikte på å tilby i markedet.  Fornuftig nok har de også en
+gratistjeneste, slik at de får frivillige til å gi innspill om feil i
+datagrunnlaget.  Jeg ble nylig nysgjerring på hvor mye det til koste å
+kjøre på kryss og tvers i Norge, og valgte meg ut en teststrekning fra
+Oslo til Tromsø for å se hvilke beløp som gjelder.&lt;/p&gt;
+
+&lt;p&gt;Bompengekalkulatoren viser frem flere rutealternativer for et gitt
+reisesøk, og i dette tilfellet, for reise fra Oslo Sentralstasjon til
+Tromsø sentrum, viser den tre alternativ.  Merk, disse tallene gjelder
+bensindrevet personbil.  En kan velge takstkategori i
+webgrensesnittet.  Det ene rutealternativet er E6 gjennom Norge, de to
+andre er E45 og E4 gjennom sverige.  E45 er innlandsruten i Sverige,
+motorvei gjennom store skoger som i følge kalkulatoren skal ta 22
+timer og 26 minutter med norsk bompengebeløp på 164 kroner.  Jeg har
+mine tvil til om datasettet til Bompengekalkulatoren har svenske
+bomstasjoner, så ta dette beløpet med en klype salt.  E4 er veien
+langs Bottenviken og mer befolket område, og skal ta 22 timer og 50
+minutter til en norsk bompengebeløp på 71 kroner.  Den norske ruten
+langs E6 skal derimot ta 23 timer og 16 minutter og beløpe seg til 664
+kroner.  Beløpene er uten autopass-brikke, slik at en slipper å få
+bilens posisjon registrert i alle bompengeavleserne som ikke også er
+bomstasjoner.  For trailere er bompengekostnaden 2-3 ganger så høy som
+for personbil.  I tillegg til pengebeløpet, som faktureres
+etterskuddsvis og de siste årene har blitt umulig å gjøre opp kontant
+på stedet, så kommer kostnaden med å få sine personopplysninger samlet
+inn, lagret og gjort tilgjengelig for fremmede på ubestemt tid.  Jeg
+ser på den kostnaden som mye høyere en pengebeløpet som
+faktureres.&lt;/p&gt;
+
+&lt;p&gt;For en tilsvarende tur fra Oslo til Bergen, så forteller
+kalkulatoren at raskeste vei er riksvei 7 på 7 timer 4 minutter med
+bompengebeløp 409 kroner.  Alternativene listet opp er E134 på 8 timer
+37 minutter med bompengebeløp 318 kroner og fylkesivei 40 på 7 timer
+30 minutter med beløp 331.  Det kan kanskje være greit å sjekke ut før
+en setter seg i bilen hvor ens personopplysninger vil bli samlet inn
+og lagret 5 fem år, når en velger hvilken rute en går for.&lt;/p&gt;
+
+&lt;p&gt;Som vanlig, hvis du bruker Bitcoin og ønsker å vise din støtte til
+det jeg driver med, setter jeg pris på om du sender Bitcoin-donasjoner
+til min adresse
+&lt;b&gt;&lt;a href=&quot;bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&quot;&gt;15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&lt;/a&gt;&lt;/b&gt;.
+Merk, betaling med bitcoin er ikke anonymt. :)&lt;/p&gt;

-               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Automatic_Google_Drive_sync_using_grive_in_Debian.html</guid>
-                <pubDate>Thu, 4 Oct 2018 15:20:00 +0200</pubDate>
-               <description>&lt;p&gt;A few days, I rescued a Windows victim over to Debian.  To try to
-rescue the remains, I helped set up automatic sync with Google Drive.
-I did not find any sensible Debian package handling this
-automatically, so I rebuild the grive2 source from
-&lt;a href=&quot;http://www.webupd8.org/&quot;&gt;the Ubuntu UPD8 PPA&lt;/a&gt; to do the
-task and added a autostart desktop entry and a small shell script to
-run in the background while the user is logged in to do the sync.
-Here is a sketch of the setup for future reference.&lt;/p&gt;
-
-&lt;p&gt;I first created &lt;tt&gt;~/googledrive&lt;/tt&gt;, entered the directory and
-ran &#39;&lt;tt&gt;grive -a&lt;/tt&gt;&#39; to authenticate the machine/user.  Next, I
-created a autostart hook in &lt;tt&gt;~/.config/autostart/grive.desktop&lt;/tt&gt;
-to start the sync when the user log in:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
-[Desktop Entry]
-Name=Google drive autosync
-Type=Application
-Exec=/home/user/bin/grive-sync
-&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;Finally, I wrote the &lt;tt&gt;~/bin/grive-sync&lt;/tt&gt; script to sync
-~/googledrive/ with the files in Google Drive.&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
-#!/bin/sh
-set -e
-cd ~/
-cleanup() {
-    if [ &quot;$syncpid&quot; ] ; then
-        kill $syncpid
-    fi
-}
-trap cleanup EXIT INT QUIT
-/usr/lib/grive/grive-sync.sh listen googledrive 2&gt;&amp;1 | sed &quot;s%^%$0:%&quot; &amp;
-syncpdi=$!
-while true; do
-    if ! xhost &gt;/dev/null 2&gt;&amp;1 ; then
-        echo &quot;no DISPLAY, exiting as the user probably logged out&quot;
-        exit 1
-    fi
-    if [ ! -e /run/user/1000/grive-sync.sh_googledrive ] ; then
-        /usr/lib/grive/grive-sync.sh sync googledrive
-    fi
-    sleep 300
-done 2&gt;&amp;1 | sed &quot;s%^%$0:%&quot;
-&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;Feel free to use the setup if you want.  It can be assumed to be
-GNU GPL v2 licensed (or any later version, at your leisure), but I
-doubt this code is possible to claim copyright on.&lt;/p&gt;

+               <description>&lt;p&gt;I am very happy to report that a more reliable
+&lt;a href=&quot;https://tracker.debian.org/pkg/vlc-plugin-bittorrent&quot;&gt;VLC
+bittorrent plugin&lt;/a&gt; was just uploaded into debian.  This fixes a
+couple of crash bugs in the plugin, hopefully making the VLC
+experience even better when streaming directly from a bittorrent
+source.  The package is currently in Debian unstable, but should be
+available in Debian testing in two days.  To test it, simply install
+it like this:&lt;/p&gt;
+
+&lt;p&gt;&lt;pre&gt;
+apt install vlc-plugin-bittorrent
+&lt;/pre&gt;&lt;/p&gt;
+
+&lt;p&gt;After it is installed, you can try to use it to play a file
+downloaded live via bittorrent like this:
+
+&lt;p&gt;&lt;pre&gt;
+vlc https://archive.org/download/Glass_201703/Glass_201703_archive.torrent
+&lt;/pre&gt;&lt;/p&gt;
+
+&lt;p&gt;It also support magnet links and local .torrent files.&lt;/p&gt;

-               <link>http://people.skolelinux.org/pere/blog/Valutakrambod___A_python_and_bitcoin_love_story.html</link>

-               <description>&lt;p&gt;It would come as no surprise to anyone that I am interested in
-bitcoins and virtual currencies.  I&#39;ve been keeping an eye on virtual
-currencies for many years, and it is part of the reason a few months
-ago, I started writing a python library for collecting currency
-exchange rates and trade on virtual currency exchanges.  I decided to
-name the end result valutakrambod, which perhaps can be translated to
-small currency shop.&lt;/p&gt;
-
-&lt;p&gt;The library uses the tornado python library to handle HTTP and
-websocket connections, and provide a asynchronous system for
-connecting to and tracking several services.  The code is available
-from
-&lt;a href=&quot;http://github.com/petterreinholdtsen/valutakrambod&quot;&gt;github&lt;/a&gt;.&lt;/p&gt;
-
-&lt;/p&gt;There are two example clients of the library.  One is very simple and
-list every updated buy/sell price received from the various services.
-This code is started by running bin/btc-rates and call the client code
-in valutakrambod/client.py.  The simple client look like this:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
-import functools
-import tornado.ioloop
-import valutakrambod
-class SimpleClient(object):
-    def __init__(self):
-        self.services = []
-        self.streams = []
-        pass
-    def newdata(self, service, pair, changed):
-        print(&quot;%-15s %s-%s: %8.3f %8.3f&quot; % (
-            service.servicename(),
-            pair[0],
-            pair[1],
-            service.rates[pair][&#39;ask&#39;],
-            service.rates[pair][&#39;bid&#39;])
-        )
-    async def refresh(self, service):
-        await service.fetchRates(service.wantedpairs)
-    def run(self):
-        self.ioloop = tornado.ioloop.IOLoop.current()
-        self.services = valutakrambod.service.knownServices()
-        for e in self.services:
-            service = e()
-            service.subscribe(self.newdata)
-            stream = service.websocket()
-            if stream:
-                self.streams.append(stream)
-            else:
-                # Fetch information from non-streaming services immediately
-                self.ioloop.call_later(len(self.services),
-                                       functools.partial(self.refresh, service))
-                # as well as regularly
-                service.periodicUpdate(60)
-        for stream in self.streams:
-            stream.connect()
-        try:
-            self.ioloop.start()
-        except KeyboardInterrupt:
-            print(&quot;Interrupted by keyboard, closing all connections.&quot;)
-            pass
-        for stream in self.streams:
-            stream.close()
-&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;The library client loops over all known &quot;public&quot; services,
-initialises it, subscribes to any updates from the service, checks and
-activates websocket streaming if the service provide it, and if no
-streaming is supported, fetches information from the service and sets
-up a periodic update every 60 seconds.  The output from this client
-can look like this:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;

-Paymium         BTC-EUR: 5680.000 5620.240
-&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;The exchange order book is tracked in addition to the best buy/sell
-price, for those that need to know the details.&lt;/p&gt;
-
-&lt;p&gt;The other example client is focusing on providing a curses view
-with updated buy/sell prices as soon as they are received from the
-services.  This code is located in bin/btc-rates-curses and activated
-by using the &#39;-c&#39; argument.  Without the argument the &quot;curses&quot; output
-is printed without using curses, which is useful for debugging.  The
-curses view look like this:&lt;/p&gt;
-

-&lt;p&gt;The code for this client is too complex for a simple blog post, so

-to the service, the provided information was updated.  The last is an
-estimate on how often the buy/sell values change.&lt;/p&gt;
-
-&lt;p&gt;If you find this library useful, or would like to improve it, I

+                <pubDate>Tue, 12 May 2020 06:30:00 +0200</pubDate>
+               <description>&lt;p&gt;It has been way too long since my last interview, but as the
+&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt;
+community is still active, and new people keep showing up on the IRC
+channel &lt;a href=&quot;irc://irc.debian.org/#debian-edu&quot;&gt;#debian-edu&lt;/a&gt; and
+&lt;a href=&quot;https://lists.debian.org/debian-edu/&quot;&gt;the debian-edu mailing
+list&lt;/a&gt;, I decided to give it another go.  I was hoping someone else
+might pick up the idea and run with it, but this has not happened as
+far as I can tell, so here we are… This time the announcement of a new
+free software tool to
+&lt;a href=&quot;https://framagit.org/Yvan-Masson/WhosWho&quot;&gt;create a school year
+book&lt;/a&gt; triggered my interest, and I decided to learn more about its
+author.&lt;/p&gt;
+
+&lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
+
+&lt;p&gt;My name is Yvan MASSON, I live in France. I have my own one person
+business in computer services.  The work consist of visiting my
+customers (person&#39;s home, local authority, small business) to give
+advise, install computers and software, fix issues, and provide
+computing usage training.  I spend the rest of my time enjoying my
+family and promoting free software.&lt;/p&gt;
+
+&lt;p&gt;&lt;strong&gt;What is your approach for promoting free
+software?&lt;/strong&gt;&lt;/p&gt;
+
+&lt;p&gt;When I think that free software could be suitable for someone, I
+explain what it is, with simple words, give a few known examples, and
+explain that while there is no fee it is a viable alternative in many
+situations. Most people are receptive when you explain how it is
+better (I simplify arguments here, I know that it is not so simple):
+Linux works on older hardware, there are no viruses, and the software
+can be audited to ensure user is not spied upon. I think the most
+important is to keep a clear but moderated speech: when you try to
+convince too much, people feel attacked and stop listening.&lt;/p&gt;
+
+&lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux / Debian Edu
+project?&lt;/strong&gt;&lt;/p&gt;
+
+&lt;p&gt;I can not remember how I first heard of Skolelinux / Debian Edu,
+but probably on planet.debian.org. As I have been working for a
+school, I have interest in this type of project.
+
+&lt;p&gt;The school I am involved in is a school for &quot;children&quot; between 14
+and 18 years old.  The French government has recommended free software
+since 2012, but they do not always use free software themselves.  The
+school computers are still using the Windows operating system, but all
+of them have the classic set of free software: Firefox ESR,
+LibreOffice (with the excellent extension Grammalecte that indicates
+French grammatical errors), SumatraPDF, Audacity, 7zip, KeePass2, VLC,
+GIMP, Inkscape…
+
+&lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux / Debian
+Edu?&lt;/strong&gt;&lt;/p&gt;
+
+&lt;p&gt;It is free software! Built on Debian, I am sure that users are not
+spied upon, and that it can run on low end hardware.  This last point
+is very important, because we really need to improve &quot;green IT&quot;.  I do
+not know enough about Skolelinux / Debian Edu to tell how it is better
+than another free software solution, but what I like is the &quot;all in
+one&quot; solution: everything has been thought of and prepared to ease
+installation and usage.&lt;/p&gt;
+
+&lt;p&gt;I like Free Software because I hate using something that I can not
+understand. I do not say that I can understand everything nor that I
+want to understand everything, but knowing that someone / some company
+intentionally prevents me from understanding how things work is really
+unacceptable to me.&lt;/p&gt;
+
+&lt;p&gt;Secondly, and more importantly, free software is a requirement to
+prevent abuses regarding human rights and environmental care.
+Humanity can not rely on tools that are in the hands of small group of
+people.&lt;/p&gt;
+
+&lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux / Debian
+Edu?&lt;/strong&gt;&lt;/p&gt;
+
+&lt;p&gt;Again, I don&#39;t know this project enough. Maybe a dedicated website?
+Debian wiki works well for documentation, but is not very appealing to
+someone discovering the project. Also, as Skolelinux / Debian Edu uses
+OpenLDAP, it probably means that Windows workstations cannot use
+centralized authentication. Maybe the project could use Samba as an
+Active Directory domain controller instead, allowing Windows desktop
+usage when necessary.&lt;/p&gt;
+
+&lt;p&gt;(Editors note: In fact Windows workstations can
+&lt;a href=&quot;https://wiki.debian.org/DebianEdu/Documentation/Buster/HowTo/Samba&quot;&gt;use
+the centralized authentication in a Debian Edu setup&lt;/a&gt;, at least for
+some versions of Windows, but the fact that this is not well known can
+be seen as an indication of the need for better documentation and
+marketing. :)&lt;/p&gt;
+     
+&lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
+
+&lt;p&gt;Nothing original: Debian testing/sid with Gnome desktop, Firefox,
+Thunderbird, LibreOffice…&lt;/p&gt;
+     
+&lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
+get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
+
+&lt;p&gt;Every effort to spread free software into schools is important,
+whatever it is. But I think, at least where I live, that IT
+professionals maintaining schools networks are still very &quot;Microsoft
+centric&quot;.  Schools will use any working solution, but they need people
+to install and maintain it.  How to make these professionals sensitive
+about free software and train them with solutions like Debian Edu /
+Skolelinux is a really good question :-)&lt;/p&gt;

-                <pubDate>Mon, 24 Sep 2018 21:20:00 +0200</pubDate>
-               <description>&lt;p&gt;Back in February, I got curious to see
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Using_VLC_to_stream_bittorrent_sources.html&quot;&gt;if
-VLC now supported Bittorrent streaming&lt;/a&gt;.  It did not, despite the
-fact that the idea and code to handle such streaming had been floating
-around for years.  I did however find
-&lt;a href=&quot;https://github.com/johang/vlc-bittorrent&quot;&gt;a standalone plugin
-for VLC&lt;/a&gt; to do it, and half a year later I decided to wrap up the
-plugin and get it into Debian.  I uploaded it to NEW a few days ago,
-and am very happy to report that it
-&lt;a href=&quot;https://tracker.debian.org/pkg/vlc-plugin-bittorrent&quot;&gt;entered
-Debian&lt;/a&gt; a few hours ago, and should be available in Debian/Unstable
-tomorrow, and Debian/Testing in a few days.&lt;/p&gt;
-
-&lt;p&gt;With the vlc-plugin-bittorrent package installed you should be able
-to stream videos using a simple call to&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
-vlc https://archive.org/download/TheGoat/TheGoat_archive.torrent
-&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;/p&gt;It can handle magnet links too.  Now if only native vlc had
-bittorrent support.  Then a lot more would be helping each other to
-share public domain and creative commons movies.  The plugin need some
-stability work with seeking and picking the right file in a torrent
-with many files, but is already usable.  Please note that the plugin
-is not removing downloaded files when vlc is stopped, so it can fill
-up your disk if you are not careful.  Have fun. :)&lt;/p&gt;
-
-&lt;p&gt;I would love to get help maintaining this package.  Get in touch if
-you are interested.&lt;/p&gt;

+                <pubDate>Fri, 8 May 2020 13:30:00 +0200</pubDate>
+               <description>&lt;p&gt;Half a year ago,
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Jami_Ring__finally_functioning_peer_to_peer_communication_client.html&quot;&gt;I
+wrote&lt;/a&gt; about &lt;a href=&quot;https://jami.net/&quot;&gt;the Jami communication
+client&lt;/a&gt;, capable of peer-to-peer encrypted communication.  It
+handle both messages, audio and video.  It uses distributed hash
+tables instead of central infrastructure to connect its users to each
+other, which in my book is a plus.  I mentioned briefly that it could
+also work as a SIP client, which came in handy when the higher
+educational sector in Norway started to promote Zoom as its video
+conferencing solution.  I am reluctant to use the official Zoom client
+software, due to their &lt;a href=&quot;https://zoom.us/terms&quot;&gt;copyright
+license clauses&lt;/a&gt; prohibiting users to reverse engineer (for example
+to check the security) and benchmark it, and thus prefer to connect to
+Zoom meetings with free software clients.&lt;/p&gt;
+
+&lt;p&gt;Jami worked OK as a SIP client to Zoom as long as there was no
+password set on the room.  The Jami daemon leak memory like crazy
+(approximately 1 GiB a minute) when I am connected to the video
+conference, so I had to restart the client every 7-10 minutes, which
+is not a great.  I tried to get other SIP Linux clients to work
+without success, so I decided I would have to live with this wart
+until someone managed to fix the leak in the dring code base.  But
+another problem showed up once the rooms were password protected.  I
+could not get my dial tone signaling through from Jami to Zoom, and
+dial tone signaling is used to enter the password when connecting to
+Zoom.  I tried a lot of different permutations with my Jami and
+Asterisk setup to try to figure out why the signaling did not get
+through, only to finally discover that the fundamental problem seem to
+be that Zoom is simply not able to receive dial tone signaling when
+connecting via SIP.  There seem to be nothing wrong with the Jami and
+Asterisk end, it is simply broken in the Zoom end.  I got help from a
+very skilled VoIP engineer figuring out this last part.  And being a
+very skilled engineer, he was also able to locate a solution for me.
+Or to be exact, a workaround that solve my initial problem of
+connecting to password protected Zoom rooms using Jami.&lt;/p&gt;
+
+&lt;p&gt;So, how do you do this, I am sure you are wondering by now.  The
+trick is already
+&lt;a href=&quot;https://support.zoom.us/hc/en-us/articles/202405539-H-323-SIP-Room-Connector-Dial-Strings#sip&quot;&gt;documented
+from Zoom&lt;/a&gt;, and it is to modify the SIP address to include the room
+password.  What is most surprising about this is that the
+automatically generated email from Zoom with instructions on how to
+connect via SIP do not mention this.  The SIP address to use normally
+consist of the room ID (a number), an @ character and the IP address
+of the Zoom SIP gateway.  But Zoom understand a lot more than just the
+room ID in front of the at sign.  The format is &quot;&lt;tt&gt;[Meeting
+ID].[Password].[Layout].[Host Key]&lt;/tt&gt;&quot;, and you can hear see how you
+can both enter password, control the layout (full screen, active
+presence and gallery) and specify the host key to start the meeting.
+The full SIP address entered into Jami to provide the password will
+then look like this (all using made up numbers):&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;
+&lt;tt&gt;sip:657837644.522827@192.168.169.170&lt;/tt&gt;
+&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;Now if only jami would reduce its memory usage, I could even
+recommend this setup to others. :)&lt;/p&gt;

-               <description>&lt;p&gt;I continue to explore my Kodi installation, and today I wanted to
-tell it to play a youtube URL I received in a chat, without having to
-insert search terms using the on-screen keyboard.  After searching the
-web for API access to the Youtube plugin and testing a bit, I managed
-to find a recipe that worked.  If you got a kodi instance with its API
-available from http://kodihost/jsonrpc, you can try the following to
-have check out a nice cover band.&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;curl --silent --header &#39;Content-Type: application/json&#39; \
-  --data-binary &#39;{ &quot;id&quot;: 1, &quot;jsonrpc&quot;: &quot;2.0&quot;, &quot;method&quot;: &quot;Player.Open&quot;,
-  &quot;params&quot;: {&quot;item&quot;: { &quot;file&quot;:
-  &quot;plugin://plugin.video.youtube/play/?video_id=LuRGVM9O0qg&quot; } } }&#39; \
-  http://projector.local/jsonrpc&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;I&#39;ve extended kodi-stream program to take a video source as its
-first argument.  It can now handle direct video links, youtube links
-and &#39;desktop&#39; to stream my desktop to Kodi.  It is almost like a
-Chromecast. :)&lt;/p&gt;

+               <description>&lt;p&gt;The curiosity got the better of me when
+&lt;a href=&quot;https://developers.slashdot.org/story/20/04/06/1424246/new-jersey-desperately-needs-cobol-programmers&quot;&gt;Slashdot
+reported&lt;/a&gt; that New Jersey was desperately looking for
+&lt;a href=&quot;https://en.wikipedia.org/wiki/COBOL&quot;&gt;COBOL&lt;/a&gt; programmers,
+and a few days later it was reported that
+&lt;a href=&quot;https://onezero.medium.com/ibm-rallies-cobol-engineers-to-save-overloaded-unemployment-systems-eeadf13eddce&quot;&gt;IBM
+tried to locate COBOL programmers&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;I thus decided to have a look at free software alternatives to
+learn COBOL, and had the pleasure to find
+&lt;a href=&quot;https://sourceforge.net/projects/open-cobol/&quot;&gt;GnuCOBOL&lt;/a&gt; was
+already &lt;a href=&quot;https://tracker.debian.org/pkg/gnucobol&quot;&gt;in
+Debian&lt;/a&gt;.  It used to be called Open Cobol, and is a &quot;compiler&quot;
+transforming COBOL code to C or C++ before giving it to GCC or Visual
+Studio to build binaries.&lt;/p&gt;
+
+&lt;p&gt;I managed to get in touch with upstream, and was impressed with the
+quick response, and also was happy to see a new Debian maintainer
+taking over when the original one recently asked to be replaced.  A
+new Debian upload was done as recently as yesterday.&lt;/p&gt;
+
+&lt;p&gt;Using the Debian package, I was able to follow a simple COBOL
+introduction and make and run simple COBOL programs.  It was fun to
+learn a new programming language.  If you want to test for yourself,
+&lt;a href=&quot;https://en.wikipedia.org/wiki/GnuCOBOL&quot;&gt;the GnuCOBOL Wikipedia
+page&lt;/a&gt; have a few simple examples to get you startet.&lt;/p&gt;
+
+&lt;p&gt;As I do not have much experience with COBOL, I do not know how
+standard compliant it is, but it claim to pass most tests from COBOL
+test suite, which sound good to me.  It is nice to know it is possible
+to learn COBOL using software without any usage restrictions, and I am
+very happy such nice free software project as this is available.  If
+you as me is curious about COBOL, check it out.&lt;/p&gt;

+               <description>&lt;p&gt;Jeg er blitt spurt hva jeg synes om lansering av smittestopp-appen,
+overvåkningsløsningen lansert av Folkehelseinstituttet,
+Simula-senteret og Regjeringen i dag, fulgt av klare trusler fra
+regjeringen om konsekvenser hvis befolkningen ikke tar den i bruk.
+Rekker ikke skrive noe fyldig om temaet, men det er klart for meg at
+den utraderer retten til privatliv samt utgjør en personlig
+sikkerhetsrisiko for alle som tar den i bruk.  Bare det er nok til at
+det fremstår som en svært dårlig ide å bli med på denne &quot;dugnaden&quot;.
+Det finnes andre og bedre tilnærminger enn den valgt av FHI.  Har de
+valgt sin tilnærming for å sikre seg nok et datasett i den fremtidige
+ehelse-portalen?  Potensialet for misbruk av informasjon samlet inn av
+appen er for stort, effekten på neste krise for klar og gevinsten for
+liten.&lt;/p&gt;
+
+&lt;p&gt;For å si det med forhenværende leder i Datatilsynet, Georg Apenes,
+som skrev i en kronikk den gang Datatilsynet vernet
+privatsfæren at
+«&lt;a href=&quot;https://www.dagbladet.no/kultur/rent-mel-i-bilen/66333882&quot;&gt;SENTRALT
+I en liberal forestillingsverden finner vi aksept av borgerens rett
+til å kunne velge å være i fred; å være u-iakttatt, uregistrert og
+anonym&lt;/a&gt;».  Det er ikke uten grunn han startet kronikken med
+«Personvern et fremmedord i enkelte av de statsorganene som samler
+inn, oppbevarer og bruker personopplysninger».  Der har nok
+statsorganene bare blitt dårligere på 13 år.&lt;/p&gt;
+
+&lt;p&gt;Det er jo også verdt å merke seg at personvernrådet i EU (EDPB)
+mener smittestopp-appen
+&lt;a href=&quot;https://nrkbeta.no/2020/04/16/personvernrad-i-eu-mener-norsk-app-bryter-med-viktig-personvernprinsipp/&quot;&gt;opererer
+i strid med prinsippet om dataminimering&lt;/a&gt;.  Også de ser at det
+finnes mye bedre måter å gjøre dette på.&lt;/p&gt;

-               <link>http://people.skolelinux.org/pere/blog/A_bit_more_on_privacy_respecting_health_monitor___fitness_tracker.html</link>
-               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/A_bit_more_on_privacy_respecting_health_monitor___fitness_tracker.html</guid>
-                <pubDate>Mon, 13 Aug 2018 09:00:00 +0200</pubDate>
-               <description>&lt;p&gt;A few days ago, I wondered if there are any privacy respecting
-health monitors and/or fitness trackers available for sale these days.
-I would like to buy one, but do not want to share my personal data
-with strangers, nor be forced to have a mobile phone to get data out
-of the unit.  I&#39;ve received some ideas, and would like to share them
-with you.
-
-One interesting data point was a pointer to a Free Software app for
-Android named
-&lt;a href=&quot;https://github.com/Freeyourgadget/Gadgetbridge/&quot;&gt;Gadgetbridge&lt;/a&gt;.
-It provide cloudless collection and storing of data from a variety of
-trackers.  Its
-&lt;a href=&quot;https://github.com/Freeyourgadget/Gadgetbridge/#supported-devices&quot;&gt;list
-of supported devices&lt;/a&gt; is a good indicator for units where the
-protocol is fairly open, as it is obviously being handled by Free
-Software.  Other units are reportedly encrypting the collected
-information with their own public key, making sure only the vendor
-cloud service is able to extract data from the unit.  The people
-contacting me about Gadgetbirde said they were using
-&lt;a href=&quot;https://us.amazfit.com/shop/bip?variant=336750&quot;&gt;Amazfit
-Bip&lt;/a&gt; and
-&lt;a href=&quot;http://www.xiaomimi6phone.com/xiaomi-mi-band-3-features-release-date-rumors/&quot;&gt;Xiaomi
-Band 3&lt;/a&gt;.&lt;/p&gt;
-
-&lt;p&gt;I also got a suggestion to look at some of the units from Garmin.
-I was told their GPS watches can be connected via USB and show up as a
-USB storage device with
-&lt;a href=&quot;https://www.gpsbabel.org/htmldoc-development/fmt_garmin_fit.html&quot;&gt;Garmin
-FIT files&lt;/a&gt; containing the collected measurements.  While
-proprietary, FIT files apparently can be read at least by
-&lt;a href=&quot;https://www.gpsbabel.org&quot;&gt;GPSBabel&lt;/a&gt; and the
-&lt;a href=&quot;https://apps.nextcloud.com/apps/gpxpod&quot;&gt;GpxPod&lt;/a&gt; Nextcloud
-app.  It is unclear to me if they can read step count and heart rate
-data.  The person I talked to was using a
-&lt;a href=&quot;https://buy.garmin.com/en-US/US/p/564291&quot;&gt;Garmin Forerunner
-935&lt;/a&gt;, which is a fairly expensive unit.  I doubt it is worth it for
-a unit where the vendor clearly is trying its best to move from open
-to closed systems.  I still remember when Garmin dropped NMEA support
-in its GPSes.&lt;/p&gt;
-
-&lt;p&gt;A final idea was to build ones own unit, perhaps by basing it on a
-wearable hardware platforms like
-&lt;a href=&quot;https://learn.adafruit.com/flora-geo-watch&quot;&gt;the Flora Geo
-Watch&lt;/a&gt;.  Sound like fun, but I had more money than time to spend on
-the topic, so I suspect it will have to wait for another time.&lt;/p&gt;
-
-&lt;p&gt;While I was working on tracking down links, I came across an
-inspiring TED talk by Dave Debronkart about
-&lt;a href=&quot;https://archive.org/details/DavedeBronkart_2010X&quot;&gt;being a
-e-patient&lt;/a&gt;, and discovered the web site
-&lt;a href=&quot;https://participatorymedicine.org/epatients/&quot;&gt;Participatory
-Medicine&lt;/a&gt;.  If you too want to track your own health and fitness
-without having information about your private life floating around on
-computers owned by others, I recommend checking it out.&lt;/p&gt;

+               <description>&lt;p&gt;Det er lenge siden jeg har sett på den norske stavekontrollen, sist
+jeg skrev om temaet var i 2016, og i mellomtiden har nettstedet
+no.speling.org forsvunnet, og både git-depotet på Alioth og
+mailman-tjenesten som hadde epostlistene for oversettelser blitt lagt
+ned.  Men bokmål og nynorsk trenger fortsatt stavekontroll, så etter
+et par purringer fra en som har lyst til å forbedre stavekontrollen
+har jeg endelig fått lagt ut ny offentlig kopi av git-depotet.  Jeg
+valgte gitlab foran github..  Siste utgave av stavekontrollen kan
+hentes ned fra
+&lt;a href=&quot;https://gitlab.com/norwegian-language-tools/spell-norwegian&quot;&gt;https://gitlab.com/norwegian-language-tools/spell-norwegian&lt;/a&gt;.
+Ingen ny versjon i denne omgang altså, bare et nytt sted å samle
+forbedringer til den frie norske stavekontrollen. :)

-               <description>&lt;p&gt;Dear lazyweb,&lt;/p&gt;
-
-&lt;p&gt;I wonder, is there a fitness tracker / health monitor available for
-sale today that respect the users privacy?  With this I mean a
-watch/bracelet capable of measuring pulse rate and other
-fitness/health related values (and by all means, also the correct time
-and location if possible), which is &lt;strong&gt;only&lt;/strong&gt; provided for
-me to extract/read from the unit with computer without a radio beacon
-and Internet connection.  In other words, it do not depend on a cell
-phone app, and do make the measurements available via other peoples
-computer (aka &quot;the cloud&quot;).  The collected data should be available
-using only free software.  I&#39;m not interested in depending on some
-non-free software that will leave me high and dry some time in the
-future.  I&#39;ve been unable to find any such unit.  I would like to buy
-it.  The ones I have seen for sale here in Norway are proud to report
-that they share my health data with strangers (aka &quot;cloud enabled&quot;).
-Is there an alternative?  I&#39;m not interested in giving money to people
-requiring me to accept &quot;privacy terms&quot; to allow myself to measure my
-own health.&lt;/p&gt;

+      &lt;li&gt;Corrected to use new official relation keys when possible.&lt;/li&gt;
+      &lt;li&gt;Renamed Sakspart to Part and connect it to Mappe, Registrering
+      and Dokumentbeskrivelse instead of only Saksmappe.&lt;/li&gt;

+  &lt;li&gt;No longer exposes attribute Dokumentobjekt.referanseDokumentfil,
+   one should use the relation in _links instead.&lt;/li&gt;
+  &lt;li&gt;Corrected relation keys under
+   https://rel.arkivverket.no/noark5/v5/api/administrasjon/, replacing
+   &#39;administrasjon&#39; with &#39;admin&#39;.&lt;/li&gt;
+  &lt;li&gt;Fixed several security and stability issues discovered by Coverity.&lt;/li&gt;
+  &lt;li&gt;Corrected handling ETag errors, now return code 409.&lt;/li&gt;

+  &lt;li&gt;Changed instance lists with subtypes (like .../registrering/ and
+   .../mappe/) to include the attributes and _links entries for the
+   subtype in the supertype lists.&lt;/li&gt;
+  &lt;li&gt;Adjusted _links relations to make it possible to figure out the
+   entity of an instance using the self-&gt;href-&gt;relation key lookup
+   method.&lt;/li&gt;
+  &lt;li&gt;Fixed several end points to make sure GET, PUT, POST and DELETE

+  &lt;li&gt;Updated DELETE endpoints to work with UUID based entity

+  &lt;li&gt;Restructured code to use more common URL related constants in entry

+  &lt;li&gt;Added first unit test code.&lt;/li&gt;
+  &lt;li&gt;Updated web GUI to work with the updated API.&lt;/li&gt;
+  &lt;li&gt;Changed integer fields, enforce them as numeric.&lt;/li&gt;
+  &lt;li&gt;Rewrote and simplify metadata handling to use common service and
+   controller code instead of duplicating for each type.&lt;/li&gt;
+  &lt;li&gt;Implemented the remaining metadata types.&lt;/li&gt;
+  &lt;li&gt;Changed Country list source from Wikipedia to Debian iso-codes and

+  &lt;li&gt;Many many corrections and improvements.&lt;/li&gt;

-               <description>&lt;p&gt;For a while now, I have looked for a sensible way to share images
-with my family using a self hosted solution, as it is unacceptable to
-place images from my personal life under the control of strangers
-working for data hoarders like Google or Dropbox.  The last few days I
-have drafted an approach that might work out, and I would like to
-share it with you.  I would like to publish images on a server under
-my control, and point some Internet connected display units using some
-free and open standard to the images I published.  As my primary
-language is not limited to ASCII, I need to store metadata using
-UTF-8.  Many years ago, I hoped to find a digital photo frame capable
-of reading a RSS feed with image references (aka using the
-&amp;lt;enclosure&amp;gt; RSS tag), but was unable to find a current supplier
-of such frames.  In the end I gave up that approach.&lt;/p&gt;
-
-&lt;p&gt;Some months ago, I discovered that
-&lt;a href=&quot;https://www.jwz.org/xscreensaver/&quot;&gt;XScreensaver&lt;/a&gt; is able to
-read images from a RSS feed, and used it to set up a screen saver on
-my home info screen, showing images from the Daily images feed from
-NASA.  This proved to work well.  More recently I discovered that
-&lt;a href=&quot;https://kodi.tv&quot;&gt;Kodi&lt;/a&gt; (both using
-&lt;a href=&quot;https://www.openelec.tv/&quot;&gt;OpenELEC&lt;/a&gt; and
-&lt;a href=&quot;https://libreelec.tv&quot;&gt;LibreELEC&lt;/a&gt;) provide the
-&lt;a href=&quot;https://github.com/grinsted/script.screensaver.feedreader&quot;&gt;Feedreader&lt;/a&gt;
-screen saver capable of reading a RSS feed with images and news.  For
-fun, I used it this summer to test Kodi on my parents TV by hooking up
-a Raspberry PI unit with LibreELEC, and wanted to provide them with a
-screen saver showing selected pictures from my selection.&lt;/p&gt;
-
-&lt;p&gt;Armed with motivation and a test photo frame, I set out to generate
-a RSS feed for the Kodi instance.  I adjusted my &lt;a
-href=&quot;https://freedombox.org/&quot;&gt;Freedombox&lt;/a&gt; instance, created
-/var/www/html/privatepictures/, wrote a small Perl script to extract
-title and description metadata from the photo files and generate the
-RSS file.  I ended up using Perl instead of python, as the
-libimage-exiftool-perl Debian package seemed to handle the EXIF/XMP
-tags I ended up using, while python3-exif did not.  The relevant EXIF
-tags only support ASCII, so I had to find better alternatives.  XMP
-seem to have the support I need.&lt;/p&gt;
-
-&lt;p&gt;I am a bit unsure which EXIF/XMP tags to use, as I would like to
-use tags that can be easily added/updated using normal free software
-photo managing software.  I ended up using the tags set using this
-exiftool command, as these tags can also be set using digiKam:&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-exiftool -headline=&#39;The RSS image title&#39; \
-  -description=&#39;The RSS image description.&#39; \
-  -subject+=for-family photo.jpeg
-&lt;/pre&gt;&lt;/blockquote&gt;

-&lt;p&gt;I initially tried the &quot;-title&quot; and &quot;keyword&quot; tags, but they were
-invisible in digiKam, so I changed to &quot;-headline&quot; and &quot;-subject&quot;.  I
-use the keyword/subject &#39;for-family&#39; to flag that the photo should be
-shared with my family.  Images with this keyword set are located and
-copied into my Freedombox for the RSS generating script to find.&lt;/p&gt;
-
-&lt;p&gt;Are there better ways to do this?  Get in touch if you have better
-suggestions.&lt;/p&gt;

+               <description>&lt;p&gt;On Tuesday, two scietific articles we have been working on for a
+while, was finally accepted for publication into
+&lt;a href=&quot;https://www.emerald.com/insight/publication/issn/0956-5698&quot;&gt;Records
+Management Journal&lt;/a&gt;.  Still waiting for the assigned DOI urls to
+start working, but you can have a look at the LaTeX originals here.&lt;/p&gt;
+
+&lt;p&gt;The first article is
+&quot;&lt;a href=&quot;http://people.skolelinux.org/pere/blog/images/2020-02-25-rmj-iot-record-keeping.pdf&quot;&gt;A
+record-keeping approach to managing IoT-data for government

+10.1108/RMJ-09-2019-0050&lt;a/&gt;) by Thomas Sødring, Petter Reinholdtsen
+and David Massey, and sketches some approaches for storing measurement
+data (aka Internet of Things sensor data) in a archive, thus providing
+a well defined mechanism for screening and deletion of the information &lt;/p&gt;
+
+&lt;p&gt;The second article is

+10.1108/RMJ-09-2019-0056&lt;/a&gt;) by Thomas Sødring, Petter Reinholdtsen
+and Svein Ølnes, where we describe a way for third parties to validate
+authenticity and thus improve trust in the records kept in a

-               <description>&lt;p&gt;Last night, I wrote
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Streaming_the_Linux_desktop_to_Kodi_using_VLC_and_RTSP.html&quot;&gt;a
-recipe to stream a Linux desktop using VLC to a instance of Kodi&lt;/a&gt;.
-During the day I received valuable feedback, and thanks to the
-suggestions I have been able to rewrite the recipe into a much simpler
-approach requiring no setup at all.  It is a single script that take
-care of it all.&lt;/p&gt;
-
-&lt;p&gt;This new script uses GStreamer instead of VLC to capture the
-desktop and stream it to Kodi.  This fixed the video quality issue I
-saw initially.  It further removes the need to add a m3u file on the
-Kodi machine, as it instead connects to
-&lt;a href=&quot;https://kodi.wiki/view/JSON-RPC_API/v8&quot;&gt;the JSON-RPC API in
-Kodi&lt;/a&gt; and simply ask Kodi to play from the stream created using
-GStreamer.  Streaming the desktop to Kodi now become trivial.  Copy
-the script below, run it with the DNS name or IP address of the kodi
-server to stream to as the only argument, and watch your screen show
-up on the Kodi screen.  Note, it depend on multicast on the local
-network, so if you need to stream outside the local network, the
-script must be modified.  Also note, I have no idea if audio work, as
-I only care about the picture part.&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-#!/bin/sh
-#
-# Stream the Linux desktop view to Kodi.  See
-# http://people.skolelinux.org/pere/blog/Streaming_the_Linux_desktop_to_Kodi_using_VLC_and_RTSP.html
-# for backgorund information.
-
-# Make sure the stream is stopped in Kodi and the gstreamer process is
-# killed if something go wrong (for example if curl is unable to find the
-# kodi server).  Do the same when interrupting this script.

+               <description>&lt;p&gt;Arbeidet med å lage et godt, fritt og åpent standardisert maskinelt
+grensesnitt for arkivering, med tilhørende fri
+programvareimplementasjon fortsetter.  Jeg snakker om
+&lt;a href=&quot;https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard&quot;&gt;Noark
+5 Tjenestegrensesnitt&lt;/a&gt; og
+&lt;a href=&quot;https://gitlab.com/OsloMet-ABI/nikita-noark5-core/&quot;&gt;Nikita&lt;/a&gt;.
+Siste nytt etter
+&lt;a href=&quot;https://www.nuug.no/aktiviteter/20200127-noark-seminar/&quot;&gt;seminaret
+for noen dager siden&lt;/a&gt;, er vi i Nikita-prosjektet har fått beskjed
+fra Arkivverket at det blir satt ned en redaksjon for å videreutvikle
+spesifikasjonen.  Redaksjonen består av Mona Danielsen og Anne Sofie
+Knutsen ved arkivverket, Thomas Sødring ved OsloMet, og meg selv fra
+NUUG.  De to sistenevnte tar seg av de åpenbare forbedringene, mens
+hele redaksjonen diskuterer tvilstilfeller.  Jeg håper dette vil bidra
+til at vi lykkes i å gjøre denne protokollspesifikasjonen så entydig
+og klar at den vil bidra til et velfungerende marked for
+arkivsystemer, og sikre at programmer som trenger å snakke med
+arkivsystemet kan snakke med enhver implementasjon av
+API-spesifikasjonen.  Nikita er den første implementasjonen, men det
+bør blir flere.&lt;/p&gt;
+
+&lt;p&gt;Det gjenstår riktig nok endel før vi er i mål, selv om svært mye
+allerede er på plass.  Med innspill og forslag til forbedringer fra
+alle som vil ha et leverandøruavhengig og fullstendig
+datamaskinlesbart grensesnitt til arkivet, så tror jeg vi vil
+lykkes.&lt;/p&gt;
+
+&lt;p&gt;Som vanlig, hvis du bruker Bitcoin og ønsker å vise din støtte til
+det jeg driver med, setter jeg pris på om du sender Bitcoin-donasjoner
+til min adresse

+Merk, betaling med bitcoin er ikke anonymt. :)&lt;/p&gt;
