-               <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
-import subprocess
-import tempfile
-import urllib.request
-
-def store(f, data):
-    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;I am very pleased to be able to share with you
+&lt;a href=&quot;https://lists.nuug.no/pipermail/nikita-noark/2021-June/000576.html&quot;&gt;the
+announcement of a new version of the archiving system Nikita&lt;/a&gt;
+published by its lead developer Thomas Sødring:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;
+
+&lt;p&gt;It is with great pleasure that we can announce a new release of
+nikita.  Version 0.6
+(&lt;a href=&quot;https://gitlab.com/OsloMet-ABI/nikita-noark5-core&quot;&gt;https://gitlab.com/OsloMet-ABI/nikita-noark5-core&lt;/a&gt;). This
+release makes new record keeping functionality available. This really
+is a maturity release. Both in terms of functionality but also code.
+Considerable effort has gone into refactoring the codebase and
+simplifying the code. Notable changes for this release include:&lt;/p&gt;
+
+&lt;ul&gt;
+
+  &lt;li&gt;Significantly improved OData parsing&lt;/li&gt;
+  &lt;li&gt;Support for business specific metadata and national identifiers&lt;/li&gt;
+  &lt;li&gt;Continued implementation of domain model and endpoints&lt;/li&gt;
+  &lt;li&gt;Improved testing&lt;/li&gt;
+  &lt;li&gt;Ability to export and import from arkivstruktur.xml&lt;/li&gt;
+
+&lt;/ul&gt;
+
+&lt;p&gt;We are currently in the process of reaching an agreement with an
+archive institution to publish their picture archive using nikita with
+business specific metadata and we hope that we can share this with you
+soon. This is an interesting project as it allows the organisation to
+bring an older picture archive back to life while using the original
+metadata values stored as business specific metadata. Combined with
+OData means the scope and use of the archive is significantly
+increased and will showcase both the flexibility and power of
+Noark.&lt;/p&gt;
+
+&lt;p&gt;I really think we are approaching a version 1.0 of nikita, even
+though there is still a lot of work to be done. The notable work at
+the moment is to implement access-control and full text indexing of
+documents.&lt;/p&gt;
+
+&lt;p&gt;My sincere thanks to everyone who has contributed to this
+release!&lt;/p&gt;
+
+&lt;p&gt;- Thomas&lt;/p&gt;
+
+&lt;p&gt;&lt;strong&gt;Release 0.6 2021-06-10 (d1ba5fc7e8bad0cfdce45ac20354b19d10ebbc7b)&lt;/strong&gt;&lt;/p&gt;

+       &lt;li&gt;Author&lt;/li&gt;
+       &lt;li&gt;Screening for relevant objects&lt;/li&gt;
+       &lt;li&gt;ChangeLog&lt;/li&gt;

+  &lt;li&gt;Finalise File-&gt;CaseFile expansion and Record-&gt;registryEntry/recordNote 
+expansion&lt;/li&gt;
+  &lt;li&gt;Improved Continuous Integration (CI) approach via gitlab&lt;/li&gt;

+  &lt;li&gt;Implemented storing of Precedence.&lt;/li&gt;
+  &lt;li&gt;Corrected handling of screening.&lt;/li&gt;
+  &lt;li&gt;Corrected _links collection returned for list of mixed entity types

-               <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;

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

+               <description>&lt;p&gt;I have neglected the Valutakrambod library for a while, but decided
+this weekend to give it a face lift.  I fixed a few minor glitches in
+several of the service drivers, where the API had changed since I last
+looked at the code.  I also added support for fetching the order book
+from the newcomer Norwegian Bitcoin Exchange.&lt;/p&gt;
+
+&lt;p&gt;I also decided to migrate the project from github to gitlab in the
+process.  If you want a python library for talking to various currency
+exchanges, check out
+&lt;a href=&quot;https://gitlab.com/petterreinholdtsen/valutakrambod&quot;&gt;code for
+valutakrambod&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;This is what the output from &#39;&lt;tt&gt;bin/btc-rates-curses -c&lt;/tt&gt;&#39;
+looked like a few minutes ago:&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;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;
+&lt;p&gt;Yes, I notice the negative spread on Hitbtc.  Either I fail to
+understand their Websocket API or they are sending bogus data.  I&#39;ve
+seen the same with Kraken, and suspect there is something wrong with
+the data they send.&lt;/p&gt;

-&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

-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;Etter intenst arbeid over mange måneder er endelig den norske
+utgaven av «Hvordan knuse overvåkningskapitalismen» av Cory Doctorow
+ferdig og klar til å glede millioner av lesere over hele verden.
+Følgende pressemelding ble nettopp sendt ut til norske redaksjoner:
+
+&lt;blockquote&gt;
+
+&lt;p&gt;&lt;strong&gt;Hva gjør stordata med oss, og hvordan gjør algoritmene
+«fake news» til realiter?&lt;/strong&gt;&lt;/p&gt;
+
+&lt;p&gt;Nå foreligger en viktig bok om temaet også på norsk. Boken klargjør
+og foreslår hvordan vi selv som enkeltpersoner, men også nasjonalt og
+internasjonalt kan bekjempe stordatakonsentrasjonene;
+«overvåkingskapitalismen».  Boken er «Hvordan knuse
+overvåkingskapitalismen» av dr. Cory Doctorow. Den engelske
+bokutgivelsen kom for noen dager siden og lanseres med et Webinar
+torsdag 2021-01-28. Doctorow besøkte Norge og NUUG i desember med sin
+presentasjon Monopoly, Not Mind Control: What&#39;s Really Happening With
+&quot;Surveillance Capitalism&quot;.&lt;/p&gt;
+
+&lt;p&gt;I funn etter funn, eksempel etter eksempel, gjennomgår og
+analyserer dr. Doctorow de utfordringer vi møter i større og større
+omfang. Ikke bare i USA, men også her hjemme.&lt;/p&gt;
+
+&lt;p&gt;Cory Doctorow er en britisk-kanadisk forfatter, journalist og
+aktivist, kjent for sine science fiction-romaner, for arbeidet for
+Creative Commons-bevegelsen, og for sine bidrag til reform av
+opphavsretten. Han er både æresdoktor og gjesteforeleser i
+datavitenskap ved Open University i UK, konsulent for Electronic
+Frontier Foundation, og godt kjent for innsiktsfullt å kommentere og
+skrive om digital utvikling.&lt;/p&gt;
+
+&lt;p&gt;Boken lanseres nå på norsk, både som ebok og på papir, oversatt av
+en dugnadsgjeng ledet av Petter Reinholdtsen.&lt;/p&gt;
+
+&lt;p&gt;Boken reiser noen helt grunnleggende og samfunnskritiske spørsmål:
+Hva fører det til når store deler av Internettet domineres av få store
+aktører og deres styringsverktøy og algoritmer?&lt;/p&gt;
+
+&lt;p&gt;Som individer bør vi være opptatt at grenser blir satt og håndhevet
+- grenser for overvåkning av individet, for utøvelse av kommersiell
+og politisk påvirkning, og for monopoldannelser i
+dataverdenen. Slik grensesetting styrker personvernet.&lt;/p&gt;
+
+&lt;p&gt;Konkurransetilsynet har ansvaret for at konkurranselovens § 11 skal
+forby «et dominerende foretak for utilbørlig å utnytte og misbruke
+sin dominerende stilling». Et tilsvarende forbud omfattes også av
+EØS-avtalens artikkel 54. Boken går i detalj om serien av
+innskrenkninger vi møter i valgfriheten, innskrenkninger som denne
+lovgivningen nettopp skal forhindre. Håndhevelse av en slik lovgivning
+er også til fordel for mindre næringsdrivende som uten dette får
+begrenset sine faktiske eller potensielle muligheter for vekst og
+etablering. «Slik atferd kan utgjøre et misbruk og kan ta ulike
+former», skriver Konkurransetilsynet.&lt;/p&gt;
+
+&lt;p&gt;Cory Doctorow går i sin bok lengre enn det med sine mange eksempler
+på forhold det burde vært grepet inn mot.&lt;/p&gt;
+
+&lt;p&gt;«Boken bør bidra til et sterkere engasjemen fra voktere av
+Inter­nettet nasjonalt og internasjonalt - EU medregnet» sier
+oversetter Ole-Erik Yrvin og fortsetter: «Vi har derfor
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/images/2021-01-26-knus-overvaakningskapitalismen-helleland.pdf&quot;&gt;allerede
+tatt opp bokens forslag&lt;/a&gt; direkte med Distrikts- og
+digitaliseringsminister Linda Hofstad Helleland (H) og
+Konkurransetilsynet slik at de kan følges opp.»&lt;/p&gt;
+
+&lt;p&gt;«Også Norge bør innta en pådriverrolle i denne utviklingen», sier
+Petter Reinholdtsen. «Tiden er knapp, og tilsynsmyndighetene må få
+de verktøy og de ressurser de trenger for at vi her hjemme skal oppnå
+nødvendige resultater. Dette gjelder ikke bare vår egen generasjon;
+det gjelder alle generasjoner fremover», avslutter Petter
+Reinholdsen.&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;After a lot of hard work by its maintainer Alexandre Viau and
+others, the decentralized communication platform
+&lt;a href=&quot;https://en.wikipedia.org/wiki/Jami_(software)&quot;&gt;Jami&lt;/a&gt;
+(earlier known as Ring), managed to get
+&lt;a href=&quot;https://tracker.debian.org/pkg/ring&quot;&gt;its latest version&lt;/a&gt;
+into Debian Testing.  Several of its dependencies has caused build and
+propagation problems, which all seem to be solved now.&lt;/p&gt;
+
+&lt;p&gt;In addition to the fact that Jami is decentralized, similar to how
+bittorrent is decentralized, I first of all like how it is not
+connected to external IDs like phone numbers.  This allow me to set up
+computers to send me notifications using Jami without having to find
+get a phone number for each computer.  Automatic notification via Jami
+is also made trivial thanks to the provided client side API (as a DBus
+service).  Here is my bourne shell script demonstrating how to let any
+system send a message to any Jami address.  It will create a new
+identity before sending the message, if no Jami identity exist
+already:&lt;/p&gt;
+
+&lt;p&gt;&lt;pre&gt;

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

+
+&lt;/ul&gt;

-               <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;

+
+&lt;p&gt;I am happy to report that we finally made it!  Norwegian Bokmål
+became the first translation published on paper of the new Buster
+based edition of &quot;&lt;a href=&quot;https://debian-handbook.info/&quot;&gt;The Debian
+Administrator&#39;s Handbook&lt;/a&gt;&quot;.  The print proof reading copy arrived
+some days ago, and it looked good, so now the book is approved for
+general distribution.  This updated paperback edition &lt;a
+href=&quot;https://debian-handbook.info/get/#norwegian&quot;&gt;is available from
+lulu.com&lt;/a&gt;.  The book is also available for download in electronic
+form as PDF, EPUB and Mobipocket, and can also be
+&lt;a href=&quot;https://debian-handbook.info/browse/nb-NO/stable/&quot;&gt;read online&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;I am very happy to wrap up this Creative Common licensed project,
+which concludes several months of work by several volunteers. The
+number of Linux related books published in Norwegian are few, and I
+really hope this one will gain many readers, as it is packed with deep
+knowledge on Linux and the Debian ecosystem.  The book will be
+available for various Internet book stores like Amazon and Barnes &amp;
+Noble soon, but I recommend buying
+&quot;&lt;a href=&quot;https://www.lulu.com/en/us/shop/roland-mas-and-rapha%C3%ABl-hertzog/h%C3%A5ndbok-for-debian-administratoren/paperback/product-9j7qwq.html&quot;&gt;Håndbok

-&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;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;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;As a member of the &lt;a href=&quot;https://www.nuug.no/&quot;&gt;Norwegian Unix
+User Group&lt;/a&gt;, I have the pleasure of receiving the
+&lt;a href=&quot;https://www.usenix.org/&quot;&gt;USENIX&lt;/a&gt; magazine
+&lt;a href=&quot;https://www.usenix.org/publications/login/&quot;&gt;;login:&lt;/a&gt;
+several times a year.  I rarely have time to read all the articles,
+but try to at least skim through them all as there is a lot of nice
+knowledge passed on there.  I even carry the latest issue with me most
+of the time to try to get through all the articles when I have a few
+spare minutes.&lt;/p&gt;
+
+&lt;p&gt;The other day I came across a nice article titled
+&quot;&lt;a href=&quot;https://www.usenix.org/publications/login/winter2018/oneill&quot;&gt;The
+Secure Socket API: TLS as an Operating System Service&lt;/a&gt;&quot; with a
+marvellous idea I hope can make it all the way into the POSIX standard.
+The idea is as simple as it is powerful.  By introducing a new
+socket() option IPPROTO_TLS to use TLS, and a system wide service to
+handle setting up TLS connections, one both make it trivial to add TLS
+support to any program currently using the POSIX socket API, and gain
+system wide control over certificates, TLS versions and encryption
+systems used.  Instead of doing this:&lt;/p&gt;

 
 

-if [ -n &quot;$1&quot; ]; then
-    kodihost=$1
-    shift
-else
-    kodihost=kodi.local
-fi
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+int socket = socket(PF_INET, SOCK_STREAM, IPPROTO_TCP);
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;the program code would be doing this:&lt;p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+int socket = socket(PF_INET, SOCK_STREAM, IPPROTO_TLS);
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;

-
-&lt;p&gt;I hope you find the approach useful.  I know I do.&lt;/p&gt;
+&lt;p&gt;According to the ;login: article, converting a C program to use TLS
+would normally modify only 5-10 lines in the code, which is amazing
+when compared to using for example the OpenSSL API.&lt;/p&gt;
+
+&lt;p&gt;The project has set up the
+&lt;a href=&quot;https://securesocketapi.org/&quot;&gt;https://securesocketapi.org/&lt;/a&gt;
+web site to spread the idea, and the code for a kernel module and the
+associated system daemon is available from two github repositories:

+&lt;a href=&quot;https://github.com/markoneill/ssa-daemon&quot;&gt;ssa-daemon&lt;/a&gt;.
+Unfortunately there is no explicit license information with the code,
+so its copyright status is unclear.  A
+&lt;a href=&quot;https://github.com/markoneill/ssa/issues/2&quot;&gt;request to solve
+this&lt;/a&gt; about it has been unsolved since 2018-08-17.&lt;/p&gt;
+
+&lt;p&gt;I love the idea of extending socket() to gain TLS support, and
+understand why it is an advantage to implement this as a kernel module
+and system wide service daemon, but can not help to think that it
+would be a lot easier to get projects to move to this way of setting
+up TLS if it was done with a user space approach where programs
+wanting to use this API approach could just link with a wrapper
+library.&lt;/p&gt;
+
+&lt;p&gt;I recommend you check out this simple and powerful approach to more
+secure network connections. :)&lt;/p&gt;
