-               <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;

-&lt;p&gt;As usual, if you use Bitcoin and want to show your support of my
-activities, please send Bitcoin donations to my address

+               <description>&lt;p&gt;Like før julaften ble en artikkel jeg har skrevet om vedlikehold av
+&lt;a href=&quot;https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard&quot;&gt;Noark
+5 Tjenestegrensesnitt&lt;/a&gt; og Nikita publisert i &lt;a
+href=&quot;https://www.arkivrad.no/arkivrad&quot;&gt;tidsskriftet Arkivråd&lt;/a&gt;.
+Det er basert på
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/_pen_og_gjennomsiktig_vedlikehold_av_spesifikasjonen_for_Noark_5_Tjenestegrensesnitt.html&quot;&gt;min bloggpost
+om samme tema&lt;/a&gt; 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
+&lt;a href=&quot;https://www.arkivrad.no/sites/arkivrad/files/arkivrad_03_2019_nett.pdf&quot;&gt;PDF-en
+til nummer 2019/3 på side 30-33&lt;/a&gt;.  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
+&lt;a href=&quot;https://gitlab.com/OsloMet-ABI/nikita-noark5-core/&quot;&gt;arkivsystemet
+Nikita&lt;/a&gt; kan bli enda bedre når spesifikasjonen forbedres.&lt;/p&gt;

-               <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;
-

-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
-you will have to check out the git repository to figure out how it
-work.  What I can tell is how the three last numbers on each line
-should be interpreted.  The first is how many seconds ago information
-was received from the service.  The second is how long ago, according
-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
-would love to hear from you.  Note that for some of the services I&#39;ve
-implemented a trading API.  It might be the topic of a future blog
-post.&lt;/p&gt;

+               <description>&lt;p&gt;En historie som har betydd endel for meg, og som jeg av og til
+tenker på når hverdagen tynger, ble så vidt jeg har klart å finne ut,
+skrevet av &lt;a href=&quot;https://en.wikipedia.org/wiki/Loren_Eiseley&quot;&gt;Loren
+Eiseley&lt;/a&gt; &lt;a href=&quot;https://en.wikipedia.org/wiki/The_Star_Thrower&quot;&gt;i
+flere ulike varianter&lt;/a&gt;.  På norsk tror jeg den går under navnet
+«Gutten og sjøstjernen», og jeg fant en oversettelse av en utgave av den
+hos
+&lt;a href=&quot;https://no.quora.com/Hva-er-din-favoritthistorie&quot;&gt;Quora&lt;/a&gt;.
+Fant også &lt;a href=&quot;https://www.youtube.com/watch?v=-qClChUdlfI&quot;&gt;en
+filmatisering&lt;/a&gt;, men den versjonen jeg liker best fant jeg
+&lt;a href=&quot;https://www.goodreads.com/author/quotes/56782.Loren_Eiseley&quot;&gt;hos
+Goodreads&lt;/a&gt;.  Jeg oversatte den utgaven til norsk i går, og har lyst
+til å dele den med deg:
+
+&lt;blockquote&gt;&lt;p&gt;Mens jeg tok en pause fra skrivingen og vandret på en
+øde strand ved daggry, så jeg en gutt i det fjerne bøye seg ned og
+kaste noe mens han vandret mot meg over den endeløse stranden.  Da han
+kom nærmere, kunne jeg se at han kastet sjøstjerner, som var etterlatt
+i sanden av tidevannet, tilbake i havet. Da han var nær nok spurte jeg
+ham hvorfor han jobbet så hardt på denne merkelige oppgaven. Han sa at
+solen snart ville stå opp og tørke sjøstjernene slik at de ville
+dø.&lt;/p&gt;
+
+&lt;p&gt;Jeg sa til ham at dette var helt meningsløst.  Det var kilometer på
+kilometer med strand, og det lå sjøstjerner hele veien.  En person
+alene kunne ikke gjøre noen forskjell.  Han smilte da han plukket opp
+neste sjøstjerne. Mens han kastet den så langt ut i havet som han
+klarte sa han, «for denne gjør det en forskjell».  Jeg droppet
+skrivingen og tilbrakte resten av morgenen med å kaste
+sjøstjerner.&lt;/p&gt;
+
+&lt;p&gt;- Loren Eiseley&lt;/p&gt;
+&lt;/blockquote&gt;
+
+&lt;p&gt;Kanskje noe du også kan ha glede av å tenke på når ting virker
+håpløst?&lt;/p&gt;
+
+&lt;p&gt;Teksten er gjengitt og oversatt basert på utgaven på Good Read,
+uten tillatelse fra noen andre enn meg selv.  Jeg håper på tilgivelse,
+hvis det er et problem for noen, da det er gjort i beste mening.  Hvis
+eventuell rettighetshaver tar kontakt vil jeg fjerne teksten og i
+stedet legge ut henvendelsen der teksten kreves fjernet.&lt;/p&gt;

+&lt;p&gt;Som vanlig, hvis du bruker Bitcoin og ønsker å vise din støtte til

-               <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;

-               <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;When asked to accept terms of use and privacy policies that state
+it will to remove rights I otherwise had or accept unreasonable terms
+undermining my privacy, I choose away the service.  I simply do not
+have the conscience to accept terms I have no indention of upholding.
+But how are the system and service providers to know how many people
+they scared away?  Normally I just quietly walk away.  But today, I
+tried a new approach.  I sent the following email (removing the
+specifics, as I am not out to take the specific service in question)
+to the service provider I decided to not use, to at least give them
+one data point on how many users are unhappy with their terms:&lt;/p&gt;
+
+&lt;blockquote&gt;
+From: Petter Reinholdtsen
+&lt;br&gt;Subject: When terms of use turn users away
+&lt;br&gt;To: [contact@some.site]
+&lt;br&gt;Date: Sat, 07 Dec 2019 16:30:56 +0100
+
+&lt;p&gt;Dear [Site Owner],&lt;/p&gt;
+
+&lt;p&gt;I was eager to test the system, as it seemed like a fun and
+interesting application of [some] technology, but after reading the
+terms of use and privacy policy on &amp;lt;URL:
+https://www.[some.site]/terms-of-use &amp;gt; and &amp;lt;URL:
+https://www.[some.site]/privacy-policy &amp;gt; I want you to know that I
+decided to turn away.  There were several provisions in the terms and
+policy turning me off, but the final term that convinced me was being
+asked to sign away my right to reverse engineer.&lt;/p&gt;
+
+&lt;p&gt;-- 
+&lt;br&gt;Happy hacking
+&lt;br&gt;Petter Reinholdtsen&lt;/p&gt;
+&lt;/blockquote&gt;
+
+&lt;p&gt;I do not expect much to come out of it, but sharing it here in case
+others want to give something similar a try too.  If companies
+discover their terms scare away enough people, perhaps they will be
+improved...&lt;/p&gt;

+               <link>http://people.skolelinux.org/pere/blog/What_would_it_cost_to_store_all_2018_phone_calls_in_Norway_.html</link>

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

-               <title>A bit more on privacy respecting health monitor / fitness tracker</title>
-               <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;While working on identifying and counting movies that can be
+legally shared on the Internet, I also looked at the Norwegian movies
+listed in IMDb.  So far I have identified 54 candidates published
+before 1940 that might no longer be protected by norwegian copyright
+law.  Of these, only 29 are available at least in part from the
+Norwegian National Library.  It can be assumed that the remaining 25
+movies are lost.  It seem most useful to identify the copyright status
+of movies that are not lost.  To verify that the movie is really no
+longer protected, one need to verify the list of copyright holders and
+figure out if and when they died.  I&#39;ve been able to identify some of
+them, but for some it is hard to figure out when they died.&lt;/p&gt;
+
+&lt;/p&gt;This is the list of 29 movies both available from the library and
+possibly no longer protected by copyright law.  The year range
+(1909-1979 on the first line) is year of publication and last year
+with copyright protection.&lt;/p&gt;

+
+To be sure which one of these can be legally shared on the Internet,
+in addition to verifying the right holders list is complete, one need
+to verify the death year of these persons:

+&lt;/pre&gt;
+
+&lt;p&gt;Perhaps you can help me figuring death year of those missing it, or

+
+&lt;p&gt;Several of these movies completely lack right holder information in
+IMDb and elsewhere.  Without access to a copy of the movie, it is
+often impossible to get the list of people involved in making the
+movie, making it impossible to figure out the correct copyright
+status.&lt;/p&gt;
+
+&lt;p&gt;Not listed here are the movies still protected by copyright law.
+Their copyright terms varies from 79 to 144 years, according to the
+information I have available so far.  One of the non-lost movies might
+change status next year,
+&lt;a href=&quot;https://www.imdb.com/title/tt1008007/&quot;&gt;Mustads Mono from 1920&lt;/a&gt;.
+The next one might be
+&lt;a href=&quot;https://www.imdb.com/title/tt0347215/&quot;&gt;Hvor isbjørnen ferdes
+from 1935&lt;/a&gt; in 2024.&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;

+               <description>&lt;p&gt;The recent announcement of from the New York Public Library on its
+results in
+&lt;a href=&quot;https://www.vice.com/en_us/article/kz4e3e/millions-of-books-are-secretly-in-the-public-domain-you-can-download-them-free&quot;&gt;identifying
+books published in the USA that are now in the public domain&lt;/a&gt;,
+inspired me to update the scripts I use to track down movies that are
+in the public domain.  This involved updating the script used to
+extract lists of movies believed to be in the public domain, to work
+with the latest version of the source web sites.  In particular the
+new edition of the &lt;a href=&quot;https://retrofilmvault.com/&quot;&gt;Retro Film
+Vault&lt;/a&gt; web site now seem to list all the films available from that
+distributor, bringing the films identified there to more than 12.000
+movies, and I was able to connect 46% of these to IMDB titles.&lt;/p&gt;
+
+&lt;p&gt;The new total is 16307 IMDB IDs (aka films) in the public domain or
+creative commons licensed, and unknown status for 31460 movies
+(possibly duplicates of the 16307).&lt;/p&gt;
+
+&lt;p&gt;The complete data set is available from
+&lt;a href=&quot;https://github.com/petterreinholdtsen/public-domain-free-imdb&quot;&gt;a
+public git repository&lt;/a&gt;, including the scripts used to create it.&lt;/p&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;Jeg er veldig glad for å kunne fortelle at i går ble ny versjon av
+&lt;a href=&quot;https://www.arkivverket.no/forvaltning-og-utvikling/noark-standarden/noark-5/tjenestegrensesnitt-noark5&quot;&gt;API-spesifikasjonen
+for Noark 5 Tjenestegrensesnitt&lt;/a&gt; gitt ut.  Det så lenge mørkt ut
+for sjansene for å få inn nødvendige korreksjoner i
+spesifikasjonsteksten innen rimelig tid, men takket være intens og god
+innsats fra Mona og Anne Sofie hos Arkivverket de siste ukene, så ble
+resultatet som ble gitt ut på USAs uavhengighetsdag mye bedre enn jeg
+fryktet.&lt;/p&gt;
+
+&lt;p&gt;Spesifikasjonen er
+&lt;a href=&quot;https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/&quot;&gt;tilgjengelig
+som markdown-filer i Arkivverkets github-prosjekt for dette&lt;/a&gt;, og de
+aller fleste av forslagene til forbedringer fra oss som holder på med
+&lt;a href=&quot;https://gitlab.com/OsloMet-ABI/nikita-noark5-core&quot;&gt;Nikita-prosjektet&lt;/a&gt;
+kom med i denne nye og oppdaterte spesifikasjonsteksten.  Det er
+fortsatt mye som gjenstår før den er entydig, klar og sikrer samvirke
+på tvers av leverandører, men utgangspunktet er veldig mye bedre enn
+forrige versjon fra 2016.  Ta gjerne en titt.&lt;/p&gt;
+
+&lt;p&gt;Ellers må jeg jo si at det var hyggelig å se at min forrige
+bloggpost om tjenestegrensesnittet fikk en
+&lt;a href=&quot;https://beta.arkivverket.no/post/186020592045/noark-5-versjon-50-tjenestegrensesnitt-10&quot;&gt;lenke
+fra Arkivverket Beta&lt;/a&gt;.&lt;/p&gt;

-               <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;

+               <description>&lt;p&gt;Childs need to learn how to guard their privacy too.  To help them,
+&lt;a href=&quot;https://edri.org/&quot;&gt;European Digital Rights (EDRi)&lt;/a&gt; created
+a colorful booklet providing information on several privacy related topics,
+and tips on how to protect ones privacy in the digital age.&lt;/p&gt;
+
+&lt;p&gt;The 24 page booklet titled Digital Defenders is
+&lt;a href=&quot;https://edri.org/digital-defenders-help-kids-defend-their-privacy-around-europe&quot;&gt;available
+in several languages&lt;/a&gt;.  Thanks to the valuable contributions from

+If you would like to have it available in your language too,
+&lt;a href=&quot;https://hosted.weblate.org/projects/efn/privacy4kids/&quot;&gt;contribute
+via Weblate&lt;/a&gt; and get in touch.&lt;/p&gt;
+
+&lt;p&gt;But a funny, well written and good looking PDF do not have much

-               <description>&lt;p&gt;PS: See
-&lt;ahref=&quot;http://people.skolelinux.org/pere/blog/Simple_streaming_the_Linux_desktop_to_Kodi_using_GStreamer_and_RTP.html&quot;&gt;the
-followup post&lt;/a&gt; for a even better approach.&lt;/p&gt;
-
-&lt;p&gt;A while back, I was asked by a friend how to stream the desktop to
-my projector connected to Kodi.  I sadly had to admit that I had no
-idea, as it was a task I never had tried.  Since then, I have been
-looking for a way to do so, preferable without much extra software to
-install on either side.  Today I found a way that seem to kind of
-work.  Not great, but it is a start.&lt;/p&gt;
-
-&lt;p&gt;I had a look at several approaches, for example
-&lt;a href=&quot;https://github.com/mfoetsch/dlna_live_streaming&quot;&gt;using uPnP
-DLNA as described in 2011&lt;/a&gt;, but it required a uPnP server, fuse and
-local storage enough to store the stream locally.  This is not going
-to work well for me, lacking enough free space, and it would
-impossible for my friend to get working.&lt;/p&gt;
-
-&lt;p&gt;Next, it occurred to me that perhaps I could use VLC to create a
-video stream that Kodi could play.  Preferably using
-broadcast/multicast, to avoid having to change any setup on the Kodi
-side when starting such stream.  Unfortunately, the only recipe I
-could find using multicast used the rtp protocol, and this protocol
-seem to not be supported by Kodi.&lt;/p&gt;
-
-&lt;p&gt;On the other hand, the rtsp protocol is working!  Unfortunately I
-have to specify the IP address of the streaming machine in both the
-sending command and the file on the Kodi server.  But it is showing my
-desktop, and thus allow us to have a shared look on the big screen at
-the programs I work on.&lt;/p&gt;
-
-&lt;p&gt;I did not spend much time investigating codeces.  I combined the
-rtp and rtsp recipes from
-&lt;a href=&quot;https://wiki.videolan.org/Documentation:Streaming_HowTo/Command_Line_Examples/&quot;&gt;the
-VLC Streaming HowTo/Command Line Examples&lt;/a&gt;, and was able to get
-this working on the desktop/streaming end.&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-vlc screen:// --sout \
-  &#39;#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:rtp{dst=projector.local,port=1234,sdp=rtsp://192.168.11.4:8080/test.sdp}&#39;
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;I ssh-ed into my Kodi box and created a file like this with the
-same IP address:&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-echo rtsp://192.168.11.4:8080/test.sdp \
-  &gt; /storage/videos/screenstream.m3u
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;Note the 192.168.11.4 IP address is my desktops IP address.  As far
-as I can tell the IP must be hardcoded for this to work.  In other
-words, if someone elses machine is going to do the steaming, you have
-to update screenstream.m3u on the Kodi machine and adjust the vlc
-recipe.  To get started, locate the file in Kodi and select the m3u
-file while the VLC stream is running.  The desktop then show up in my
-big screen. :)&lt;/p&gt;
-
-&lt;p&gt;When using the same technique to stream a video file with audio,
-the audio quality is really bad.  No idea if the problem is package
-loss or bad parameters for the transcode.  I do not know VLC nor Kodi
-enough to tell.&lt;/p&gt;
-
-&lt;p&gt;&lt;strong&gt;Update 2018-07-12&lt;/strong&gt;: Johannes Schauer send me a few
-succestions and reminded me about an important step.  The &quot;screen:&quot;
-input source is only available once the vlc-plugin-access-extra
-package is installed on Debian.  Without it, you will see this error
-message: &quot;VLC is unable to open the MRL &#39;screen://&#39;.  Check the log
-for details.&quot;  He further found that it is possible to drop some parts
-of the VLC command line to reduce the amount of hardcoded information.
-It is also useful to consider using cvlc to avoid having the VLC
-window in the desktop view.  In sum, this give us this command line on
-the source end
-
-&lt;blockquote&gt;&lt;pre&gt;
-cvlc screen:// --sout \
-  &#39;#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:rtp{sdp=rtsp://:8080/}&#39;
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;and this on the Kodi end&lt;p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-echo rtsp://192.168.11.4:8080/ \
-  &gt; /storage/videos/screenstream.m3u
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;Still bad image quality, though.  But I did discover that streaming
-a DVD using dvdsimple:///dev/dvd as the source had excellent video and
-audio quality, so I guess the issue is in the input or transcoding
-parts, not the rtsp part.  I&#39;ve tried to change the vb and ab
-parameters to use more bandwidth, but it did not make a
-difference.&lt;/p&gt;
-
-&lt;p&gt;I further received a suggestion from Einar Haraldseid to try using
-gstreamer instead of VLC, and this proved to work great!  He also
-provided me with the trick to get Kodi to use a multicast stream as
-its source.  By using this monstrous oneliner, I can stream my desktop
-with good video quality in reasonable framerate to the 239.255.0.1
-multicast address on port 1234:
-
-&lt;blockquote&gt;&lt;pre&gt;
-gst-launch-1.0 ximagesrc use-damage=0 ! video/x-raw,framerate=30/1 ! \
-  videoconvert ! queue2 ! \
-  x264enc bitrate=8000 speed-preset=superfast tune=zerolatency qp-min=30 \
-  key-int-max=15 bframes=2 ! video/x-h264,profile=high ! queue2 ! \
-  mpegtsmux alignment=7 name=mux ! rndbuffersize max=1316 min=1316 ! \
-  udpsink host=239.255.0.1 port=1234 ttl-mc=1 auto-multicast=1 sync=0 \
-  pulsesrc device=$(pactl list | grep -A2 &#39;Source #&#39; | \
-    grep &#39;Name: .*\.monitor$&#39; |  cut -d&quot; &quot; -f2|head -1) ! \
-  audioconvert ! queue2 ! avenc_aac ! queue2 ! mux.
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;and this on the Kodi end&lt;p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-echo udp://@239.255.0.1:1234 \
-  &gt; /storage/videos/screenstream.m3u
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;Note the trick to pick a valid pulseaudio source.  It might not
-pick the one you need.  This approach will of course lead to trouble
-if more than one source uses the same multicast port and address.
-Note the ttl-mc=1 setting, which limit the multicast packages to the
-local network.  If the value is increased, your screen will be
-broadcasted further, one network &quot;hop&quot; for each increase (read up on
-multicast to learn more. :)!&lt;/p&gt;
-
-&lt;p&gt;Having cracked how to get Kodi to receive multicast streams, I
-could use this VLC command to stream to the same multicast address.
-The image quality is way better than the rtsp approach, but gstreamer
-seem to be doing a better job.&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-cvlc screen:// --sout &#39;#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:rtp{mux=ts,dst=239.255.0.1,port=1234,sdp=sap}&#39;

+               <description>&lt;p&gt;&lt;em&gt;av Thomas Sødring (OsloMet) og Petter Reinholdtsen (foreningen
+NUUG)&lt;/em&gt;&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;
+.../sakarkiv/journalpost?filter=contains(tittel, &#39;nabovarsel&#39;)
+&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;Spørringen over vil hente en liste av alle dine journalposter der
+tittelen til journalposten inneholder ordet &#39;nabovarsel&#39;. 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.&lt;/p&gt;
+
+&lt;p&gt;Standardisering er viktig fordi det &lt;em&gt;kan&lt;/em&gt; 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.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;https://nikita.oslomet.no&quot;&gt;https://nikita.oslomet.no&lt;/a&gt; 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
+&lt;a href=&quot;https://nikita.oslomet.no/browse.html&quot;&gt;https://nikita.oslomet.no/browse.html&lt;/a&gt;
+og der se hvordan API-et fungerer mer i detalj.  Innloggingsdetaljer
+her er det samme som for brukergrensesnittet.&lt;/p&gt;
+
+&lt;p&gt;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 &quot;pakker&quot;, 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
+&lt;a href=&quot;https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/pull/120&quot;&gt;planlagt
+fjernet&lt;/a&gt; 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.&lt;/p&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;https://webchat.freenode.net?channels=#nikita&quot;&gt;https://webchat.freenode.net?channels=#nikita&lt;/a&gt;),
+og har en e-postliste nikita-noark@nuug.no hos NUUG (tilgjengelig for
+påmelding og arkiv på
+&lt;a href=&quot;https://lists.nuug.no/mailman/listinfo/nikita-noark&quot;&gt;https://lists.nuug.no/mailman/listinfo/nikita-noark&lt;/a&gt;)
+der en kan følge med eller være med oss på den spennende veien videre.
+Spesifikasjonen for Noark 5 Tjenestegrensesnitt vedlikeholdes på
