-&quot;&lt;a href=&quot;https://debian-handbook.info/&quot;&gt;The Debian Administrator&#39;s
-Handbook&lt;/a&gt;&quot;.  This test copy arrived in the mail a few days ago, and
-I am very happy to hold the result in my hand.   We spent around one and a half year translating it. This paperbook edition
-&lt;a href=&quot;https://debian-handbook.info/get/#norwegian&quot;&gt;is available
-from lulu.com&lt;/a&gt;.  If you buy it quickly, you save 25% on the list
-price.  The book is also available for download in electronic form as
-PDF, EPUB and Mobipocket, as can be
-&lt;a href=&quot;https://debian-handbook.info/browse/nb-NO/stable/&quot;&gt;read online
-as a web page&lt;/a&gt;.&lt;/p&gt;
-
-&lt;p&gt;This is the second book I publish (the first was the book

+               <description>&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;p&gt;&lt;blockquote&gt;
-«Rapporten ser ikke på informasjonssikkerhet knyttet til personlig
-  integritet.»
-&lt;/blockquote&gt;&lt;/p&gt;
+&lt;blockquote&gt;&lt;pre&gt;
+vlc screen:// --sout \

+&lt;/pre&gt;&lt;/blockquote&gt;

 
 

-&lt;p&gt;Så enkelt kan det tydeligvis gjøres når en vurderer
-informasjonssikkerheten.  Det holder vel at folkene på toppen kan si
-at «Personvernet er ivaretatt», som jo er den populære intetsigende
-frasen som gjør at mange tror enkeltindividers integritet tas vare på.
-Sitatet fikk meg til å undres på hvor ofte samme tilnærming, å bare se
-bort fra behovet for personlig itegritet, blir valgt når en velger å
-legge til rette for nok et inngrep i privatsfæren til personer i
-Norge.  Det er jo sjelden det får reaksjoner.  Historien om
-reaksjonene på Helse Sør-Østs tjenesteutsetting er jo sørgelig nok et
-unntak og toppen av isfjellet, desverre.  Tror jeg fortsatt takker nei
-til både AutoPASS og holder meg så langt unna det norske helsevesenet
-som jeg kan, inntil de har demonstrert og dokumentert at de verdsetter
-individets privatsfære og personlige integritet høyere enn kortsiktig
-gevist og samfunnsnytte.&lt;/p&gt;

- &lt;li&gt;Added support for modifying entities using PUT and eTag.&lt;/li&gt;
- &lt;li&gt;Added support for returning XML output on request.&lt;/li&gt;
- &lt;li&gt;Removed support for English field and class names, limiting ourself
-   to the official names.&lt;/li&gt;
- &lt;li&gt;...&lt;/li&gt;
- 
-&lt;/ul&gt;
-
-&lt;p&gt;If this sound interesting to you, please contact us on IRC (#nikita
-on irc.freenode.net) or email
-(&lt;a href=&quot;https://lists.nuug.no/mailman/listinfo/nikita-noark&quot;&gt;nikita-noark
-mailing list).&lt;/p&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.m4u 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;As usual, if you use Bitcoin and want to show your support of my
+activities, please send Bitcoin donations to my address
+&lt;b&gt;&lt;a href=&quot;bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&quot;&gt;15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&lt;/a&gt;&lt;/b&gt;.&lt;/p&gt;

-               <title>Idea for storing trusted timestamps in a Noark 5 archive</title>

-                <pubDate>Wed, 7 Jun 2017 21:40:00 +0200</pubDate>
-               <description>&lt;p&gt;&lt;em&gt;This is a copy of
-&lt;a href=&quot;https://lists.nuug.no/pipermail/nikita-noark/2017-June/000297.html&quot;&gt;an
-email I posted to the nikita-noark mailing list&lt;/a&gt;.  Please follow up
-there if you would like to discuss this topic.  The background is that
-we are making a free software archive system based on the Norwegian
-&lt;a href=&quot;https://www.arkivverket.no/forvaltning-og-utvikling/regelverk-og-standarder/noark-standarden&quot;&gt;Noark
-5 standard&lt;/a&gt; for government archives.&lt;/em&gt;&lt;/p&gt;
-
-&lt;p&gt;I&#39;ve been wondering a bit lately how trusted timestamps could be
-stored in Noark 5.
-&lt;a href=&quot;https://en.wikipedia.org/wiki/Trusted_timestamping&quot;&gt;Trusted
-timestamps&lt;/a&gt; can be used to verify that some information
-(document/file/checksum/metadata) have not been changed since a
-specific time in the past.  This is useful to verify the integrity of
-the documents in the archive.&lt;/p&gt;
-
-&lt;p&gt;Then it occured to me, perhaps the trusted timestamps could be
-stored as dokument variants (ie dokumentobjekt referered to from
-dokumentbeskrivelse) with the filename set to the hash it is
-stamping?&lt;/p&gt;
-
-&lt;p&gt;Given a &quot;dokumentbeskrivelse&quot; with an associated &quot;dokumentobjekt&quot;,
-a new dokumentobjekt is associated with &quot;dokumentbeskrivelse&quot; with the
-same attributes as the stamped dokumentobjekt except these
-attributes:&lt;/p&gt;
-
-&lt;ul&gt;
-
-&lt;li&gt;format -&gt; &quot;RFC3161&quot;
-&lt;li&gt;mimeType -&gt; &quot;application/timestamp-reply&quot;
-&lt;li&gt;formatDetaljer -&gt; &quot;&amp;lt;source URL for timestamp service&amp;gt;&quot;
-&lt;li&gt;filenavn -&gt; &quot;&amp;lt;sjekksum&amp;gt;.tsr&quot;
-
-&lt;/ul&gt;
-
-&lt;p&gt;This assume a service following
-&lt;a href=&quot;https://tools.ietf.org/html/rfc3161&quot;&gt;IETF RFC 3161&lt;/a&gt; is
-used, which specifiy the given MIME type for replies and the .tsr file
-ending for the content of such trusted timestamp.  As far as I can
-tell from the Noark 5 specifications, it is OK to have several
-variants/renderings of a dokument attached to a given
-dokumentbeskrivelse objekt.  It might be stretching it a bit to make
-some of these variants represent crypto-signatures useful for
-verifying the document integrity instead of representing the dokument
-itself.&lt;/p&gt;
-
-&lt;p&gt;Using the source of the service in formatDetaljer allow several
-timestamping services to be used.  This is useful to spread the risk
-of key compromise over several organisations.  It would only be a
-problem to trust the timestamps if all of the organisations are
-compromised.&lt;/p&gt;
-
-&lt;p&gt;The following oneliner on Linux can be used to generate the tsr
-file.  $input is the path to the file to checksum, and $sha256 is the
-SHA-256 checksum of the file (ie the &quot;&lt;sjekksum&gt;.tsr&quot; value mentioned
-above).&lt;/p&gt;

+the task a lot easier.  This made me want to repeat the measurement,
+to see how much things changed.  Here are the new numbers, for
+unstable only this time:
+
+&lt;p&gt;&lt;strong&gt;Debian Unstable:&lt;/strong&gt;&lt;/p&gt;
+
+&lt;pre&gt;
+  count MIME type
+  ----- -----------------------
+     56 image/jpeg
+     55 image/png
+     49 image/tiff
+     48 image/gif
+     39 image/bmp
+     38 text/plain
+     37 audio/mpeg
+     34 application/ogg
+     33 audio/x-flac
+     32 audio/x-mp3
+     30 audio/x-wav
+     30 audio/x-vorbis+ogg
+     29 image/x-portable-pixmap
+     27 inode/directory
+     27 image/x-portable-bitmap
+     27 audio/x-mpeg
+     26 application/x-ogg
+     25 audio/x-mpegurl
+     25 audio/ogg
+     24 text/html
+&lt;/pre&gt;
+
+&lt;p&gt;The list was created like this using a sid chroot: &quot;cat
+/var/lib/apt/lists/*sid*_dep11_Components-amd64.yml.gz| zcat | awk &#39;/^
+- \S+\/\S+$/ {print $2 }&#39; | sort | uniq -c | sort -nr | head -20&quot;&lt;/p&gt;
+
+&lt;p&gt;It is interesting to see how image formats have passed text/plain
+as the most announced supported MIME type.  These days, thanks to the
+AppStream system, if you run into a file format you do not know, and
+want to figure out which packages support the format, you can find the
+MIME type of the file using &quot;file --mime &amp;lt;filename&amp;gt;&quot;, and then
+look up all packages announcing support for this format in their
+AppStream metadata (XML or .desktop file) using &quot;appstreamcli
+what-provides mimetype &amp;lt;mime-type&amp;gt;.  For example if you, like
+me, want to know which packages support inode/directory, you can get a
+list like this:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+% appstreamcli what-provides mimetype inode/directory | grep Package: | sort
+Package: anjuta
+Package: audacious
+Package: baobab
+Package: cervisia
+Package: chirp
+Package: dolphin
+Package: doublecmd-common
+Package: easytag
+Package: enlightenment
+Package: ephoto
+Package: filelight
+Package: gwenview
+Package: k4dirstat
+Package: kaffeine
+Package: kdesvn
+Package: kid3
+Package: kid3-qt
+Package: nautilus
+Package: nemo
+Package: pcmanfm
+Package: pcmanfm-qt
+Package: qweborf
+Package: ranger
+Package: sirikali
+Package: spacefm
+Package: spacefm
+Package: vifm
+%
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;Using the same method, I can quickly discover that the Sketchup file
+format is not yet supported by any package in Debian:&lt;/p&gt;

 
 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
 
 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;

-openssl ts -query -data &quot;$inputfile&quot; -cert -sha256 -no_nonce \
-  | curl -s -H &quot;Content-Type: application/timestamp-query&quot; \
-      --data-binary &quot;@-&quot; http://zeitstempel.dfn.de &gt; $sha256.tsr
+% appstreamcli what-provides mimetype  application/vnd.sketchup.skp
+Could not find component providing &#39;mimetype::application/vnd.sketchup.skp&#39;.
+%

 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 
 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 

-&lt;p&gt;To verify the timestamp, you first need to download the public key
-of the trusted timestamp service, for example using this command:&lt;/p&gt;
+&lt;p&gt;Yesterday I used it to figure out which packages support the STL 3D
+format:&lt;/p&gt;

 
 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
 
 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;

-wget -O ca-cert.txt \
-  https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt
+% appstreamcli what-provides mimetype  application/sla|grep Package
+Package: cura
+Package: meshlab
+Package: printrun
+%

 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 
 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 

-&lt;p&gt;Note, the public key should be stored alongside the timestamps in
-the archive to make sure it is also available 100 years from now.  It
-is probably a good idea to standardise how and were to store such
-public keys, to make it easier to find for those trying to verify
-documents 100 or 1000 years from now. :)&lt;/p&gt;
+&lt;p&gt;PS: A new version of Cura was uploaded to Debian yesterday.&lt;/p&gt;

 
 

-&lt;p&gt;The verification itself is a simple openssl command:&lt;/p&gt;

+               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_APT_upgrade_without_enough_free_space_on_the_disk___.html</guid>
+                <pubDate>Sun, 8 Jul 2018 12:10:00 +0200</pubDate>
+               <description>&lt;p&gt;Quite regularly, I let my Debian Sid/Unstable chroot stay untouch
+for a while, and when I need to update it there is not enough free
+space on the disk for apt to do a normal &#39;apt upgrade&#39;.  I normally
+would resolve the issue by doing &#39;apt install &amp;lt;somepackages&amp;gt;&#39; to
+upgrade only some of the packages in one batch, until the amount of
+packages to download fall below the amount of free space available.
+Today, I had about 500 packages to upgrade, and after a while I got
+tired of trying to install chunks of packages manually.  I concluded
+that I did not have the spare hours required to complete the task, and
+decided to see if I could automate it.  I came up with this small
+script which I call &#39;apt-in-chunks&#39;:&lt;/p&gt;

 
 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
 
 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;

-openssl ts -verify -data $inputfile -in $sha256.tsr \
-  -CAfile ca-cert.txt -text
+#!/bin/sh
+#
+# Upgrade packages when the disk is too full to upgrade every
+# upgradable package in one lump.  Fetching packages to upgrade using
+# apt, and then installing using dpkg, to avoid changing the package
+# flag for manual/automatic.
+
+set -e
+
+ignore() {
+    if [ &quot;$1&quot; ]; then
+       grep -v &quot;$1&quot;
+    else
+       cat
+    fi
+}
+
+for p in $(apt list --upgradable | ignore &quot;$@&quot; |cut -d/ -f1 | grep -v &#39;^Listing...&#39;); do
+    echo &quot;Upgrading $p&quot;
+    apt clean
+    apt install --download-only -y $p
+    for f in /var/cache/apt/archives/*.deb; do
+       if [ -e &quot;$f&quot; ]; then
+           dpkg -i /var/cache/apt/archives/*.deb
+           break
+       fi
+    done
+done

 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 
 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 

-&lt;p&gt;Is there any reason this approach would not work?  Is it somehow against
-the Noark 5 specification?&lt;/p&gt;
+&lt;p&gt;The script will extract the list of packages to upgrade, try to
+download the packages needed to upgrade one package, install the
+downloaded packages using dpkg.  The idea is to upgrade packages
+without changing the APT mark for the package (ie the one recording of
+the package was manually requested or pulled in as a dependency).  To
+use it, simply run it as root from the command line.  If it fail, try
+&#39;apt install -f&#39; to clean up the mess and run the script again.  This
+might happen if the new packages conflict with one of the old
+packages.  dpkg is unable to remove, while apt can do this.&lt;/p&gt;
+
+&lt;p&gt;It take one option, a package to ignore in the list of packages to
+upgrade.  The option to ignore a package is there to be able to skip
+the packages that are simply too large to unpack.  Today this was
+&#39;ghc&#39;, but I have run into other large packages causing similar
+problems earlier (like TeX).&lt;/p&gt;
+
+&lt;p&gt;Update 2018-07-08: Thanks to Paul Wise, I am aware of two
+alternative ways to handle this.  The &quot;unattended-upgrades
+--minimal-upgrade-steps&quot; option will try to calculate upgrade sets for
+each package to upgrade, and then upgrade them in order, smallest set
+first.  It might be a better option than my above mentioned script.
+Also, &quot;aptutude upgrade&quot; can upgrade single packages, thus avoiding
+the need for using &quot;dpkg -i&quot; in the script above.&lt;/p&gt;

-melder i dag&lt;/a&gt; om feil i eksamensoppgavene for eksamen i politikk og
-menneskerettigheter, der teksten i bokmåls og nynorskutgaven ikke var
-like.  Oppgaveteksten er gjengitt i artikkelen, og jeg ble nysgjerring
-på om den fri oversetterløsningen
-&lt;a href=&quot;https://www.apertium.org/&quot;&gt;Apertium&lt;/a&gt; ville gjort en bedre
-jobb enn Utdanningsdirektoratet.  Det kan se slik ut.&lt;/p&gt;
-
-&lt;p&gt;Her er bokmålsoppgaven fra eksamenen:&lt;/p&gt;
-
-&lt;blockquote&gt;
-&lt;p&gt;Drøft utfordringene knyttet til nasjonalstatenes og andre aktørers
-rolle og muligheter til å håndtere internasjonale utfordringer, som
-for eksempel flykningekrisen.&lt;/p&gt;
-
-&lt;p&gt;Vedlegge er eksempler på tekster som kan gi relevante perspektiver
-på temaet:&lt;/p&gt;
-&lt;ol&gt;
-&lt;li&gt;Flykningeregnskapet 2016, UNHCR og IDMC

-
-&lt;p&gt;Dette oversetter Apertium slik:&lt;/p&gt;
-
-&lt;blockquote&gt;
-&lt;p&gt;Drøft utfordringane knytte til nasjonalstatane sine og rolla til
-andre aktørar og høve til å handtera internasjonale utfordringar, som

-
-&lt;p&gt;Ord som ikke ble forstått er markert med stjerne (*), og trenger

+               <description>&lt;p&gt;So far, at least hydro-electric power, coal power, wind power,
+solar power, and wood power are well known.  Until a few days ago, I
+had never heard of stone power.  Then I learn about a quarry in a
+mountain in
+&lt;a href=&quot;https://en.wikipedia.org/wiki/Bremanger&quot;&gt;Bremanger&lt;/a&gt; i
+Norway, where
+&lt;a href=&quot;https://www.bontrup.com/en/activities/raw-materials/bremanger-quarry/&quot;&gt;the
+Bremanger Quarry&lt;/a&gt; company is extracting stone and dumping the stone
+into a shaft leading to its shipping harbour.  This downward movement
+in this shaft is used to produce electricity.  In short, it is using
+falling rocks instead of falling water to produce electricity, and
+according to its own statements it is producing more power than it is
+using, and selling the surplus electricity to the Norwegian power
+grid.  I find the concept truly amazing.  Is this the worlds only
+stone power plant?&lt;/p&gt;

-               <title>Epost inn som arkivformat i Riksarkivarens forskrift?</title>
-               <link>http://people.skolelinux.org/pere/blog/Epost_inn_som_arkivformat_i_Riksarkivarens_forskrift_.html</link>
-               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Epost_inn_som_arkivformat_i_Riksarkivarens_forskrift_.html</guid>
-                <pubDate>Thu, 27 Apr 2017 11:30:00 +0200</pubDate>
-               <description>&lt;p&gt;I disse dager, med frist 1. mai, har Riksarkivaren ute en høring på
-sin forskrift.  Som en kan se er det ikke mye tid igjen før fristen
-som går ut på søndag.  Denne forskriften er det som lister opp hvilke
-formater det er greit å arkivere i
-&lt;a href=&quot;http://www.arkivverket.no/arkivverket/Offentleg-forvalting/Noark/Noark-5&quot;&gt;Noark
-5-løsninger&lt;/a&gt; i Norge.&lt;/p&gt;
-
-&lt;p&gt;Jeg fant høringsdokumentene hos
-&lt;a href=&quot;https://www.arkivrad.no/aktuelt/riksarkivarens-forskrift-pa-horing&quot;&gt;Norsk
-Arkivråd&lt;/a&gt; etter å ha blitt tipset på epostlisten til
-&lt;a href=&quot;https://github.com/hiOA-ABI/nikita-noark5-core&quot;&gt;fri
-programvareprosjektet Nikita Noark5-Core&lt;/a&gt;, som lager et Noark 5
-Tjenestegresesnitt.  Jeg er involvert i Nikita-prosjektet og takket
-være min interesse for tjenestegrensesnittsprosjektet har jeg lest en
-god del Noark 5-relaterte dokumenter, og til min overraskelse oppdaget
-at standard epost ikke er på listen over godkjente formater som kan
-arkiveres.  Høringen med frist søndag er en glimrende mulighet til å
-forsøke å gjøre noe med det.  Jeg holder på med
-&lt;a href=&quot;https://github.com/petterreinholdtsen/noark5-tester/blob/master/docs/hoering-arkivforskrift.tex&quot;&gt;egen
-høringsuttalelse&lt;/a&gt;, og lurer på om andre er interessert i å støtte
-forslaget om å tillate arkivering av epost som epost i arkivet.&lt;/p&gt;
-
-&lt;p&gt;Er du igang med å skrive egen høringsuttalelse allerede?  I så fall
-kan du jo vurdere å ta med en formulering om epost-lagring. Jeg tror
-ikke det trengs så mye.  Her et kort forslag til tekst:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;
-
-  &lt;p&gt;Viser til høring sendt ut 2017-02-17 (Riksarkivarens referanse
-  2016/9840 HELHJO), og tillater oss å sende inn noen innspill om
-  revisjon av Forskrift om utfyllende tekniske og arkivfaglige
-  bestemmelser om behandling av offentlige arkiver (Riksarkivarens
-  forskrift).&lt;/p&gt;
-
-  &lt;p&gt;Svært mye av vår kommuikasjon foregår i dag på e-post.  Vi
-  foreslår derfor at Internett-e-post, slik det er beskrevet i IETF
-  RFC 5322,
-  &lt;a href=&quot;https://tools.ietf.org/html/rfc5322&quot;&gt;https://tools.ietf.org/html/rfc5322&lt;/a&gt;. bør
-  inn som godkjent dokumentformat.  Vi foreslår at forskriftens
-  oversikt over godkjente dokumentformater ved innlevering i § 5-16
-  endres til å ta med Internett-e-post.&lt;/p&gt;
-
-&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;Som del av arbeidet med tjenestegrensesnitt har vi testet hvordan
-epost kan lagres i en Noark 5-struktur, og holder på å skrive et
-forslag om hvordan dette kan gjøres som vil bli sendt over til
-arkivverket så snart det er ferdig.  De som er interesserte kan
-&lt;a href=&quot;https://github.com/petterreinholdtsen/noark5-tester/blob/master/docs/epostlagring.md&quot;&gt;følge
-fremdriften på web&lt;/a&gt;.&lt;/p&gt;
-
-&lt;p&gt;Oppdatering 2017-04-28: I dag ble høringuttalelsen jeg skrev
-  &lt;a href=&quot;https://www.nuug.no/news/NUUGs_h_ringuttalelse_til_Riksarkivarens_forskrift.shtml&quot;&gt;sendt
-  inn av foreningen NUUG&lt;/a&gt;.&lt;/p&gt;

+                <pubDate>Tue, 26 Jun 2018 23:55:00 +0200</pubDate>
+               <description>&lt;p&gt;My movie playing setup involve &lt;a href=&quot;https://kodi.tv/&quot;&gt;Kodi&lt;/a&gt;,
+&lt;a href=&quot;https://openelec.tv&quot;&gt;OpenELEC&lt;/a&gt; (probably soon to be
+replaced with &lt;a href=&quot;https://libreelec.tv/&quot;&gt;LibreELEC&lt;/a&gt;) and an
+Infocus IN76 video projector.  My projector can be controlled via both
+a infrared remote controller, and a RS-232 serial line.  The vendor of
+my projector, &lt;a href=&quot;https://www.infocus.com/&quot;&gt;InFocus&lt;/a&gt;, had been
+sensible enough to document the serial protocol in its user manual, so
+it is easily available, and I used it some years ago to write
+&lt;a href=&quot;https://github.com/petterreinholdtsen/infocus-projector-control&quot;&gt;a
+small script to control the projector&lt;/a&gt;.  For a while now, I longed
+for a setup where the projector was controlled by Kodi, for example in
+such a way that when the screen saver went on, the projector was
+turned off, and when the screen saver exited, the projector was turned
+on again.&lt;/p&gt;
+
+&lt;p&gt;A few days ago, with very good help from parts of my family, I
+managed to find a Kodi Add-on for controlling a Epson projector, and
+got in touch with its author to see if we could join forces and make a
+Add-on with support for several projectors.  To my pleasure, he was
+positive to the idea, and we set out to add InFocus support to his
+add-on, and make the add-on suitable for the official Kodi add-on
+repository.&lt;/p&gt;
+
+&lt;p&gt;The Add-on is now working (for me, at least), with a few minor
+adjustments.  The most important change I do relative to the master
+branch in the github repository is embedding the
+&lt;a href=&quot;https://github.com/pyserial/pyserial&quot;&gt;pyserial module&lt;/a&gt; in
+the add-on.  The long term solution is to make a &quot;script&quot; type
+pyserial module for Kodi, that can be pulled in as a dependency in
+Kodi.  But until that in place, I embed it.&lt;/p&gt;
+
+&lt;p&gt;The add-on can be configured to turn on the projector when Kodi
+starts, off when Kodi stops as well as turn the projector off when the
+screensaver start and on when the screesaver stops.  It can also be
+told to set the projector source when turning on the projector.
+
+&lt;p&gt;If this sound interesting to you, check out
+&lt;a href=&quot;https://github.com/fredrik-eriksson/kodi_projcontrol&quot;&gt;the
+project github repository&lt;/a&gt;.  Perhaps you can send patches to
+support your projector too?  As soon as we find time to wrap up the
+latest changes, it should be available for easy installation using any
+Kodi instance.&lt;/p&gt;
+
+&lt;p&gt;For future improvements, I would like to add projector model
+detection and the ability to adjust the brightness level of the
+projector from within Kodi.  We also need to figure out how to handle
+the cooling period of the projector.  My projector refuses to turn on
+for 60 seconds after it was turned off.  This is not handled well by
+the add-on at the moment.&lt;/p&gt;

-                <pubDate>Thu, 20 Apr 2017 13:00:00 +0200</pubDate>
-               <description>&lt;p&gt;Jeg oppdaget i dag at &lt;a href=&quot;https://www.oep.no/&quot;&gt;nettstedet som
-publiserer offentlige postjournaler fra statlige etater&lt;/a&gt;, OEP, har
-begynt å blokkerer enkelte typer webklienter fra å få tilgang.  Vet
-ikke hvor mange det gjelder, men det gjelder i hvert fall libwww-perl
-og curl.  For å teste selv, kjør følgende:&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-% curl -v -s https://www.oep.no/pub/report.xhtml?reportId=3 2&gt;&amp;1 |grep &#39;&lt; HTTP&#39;
-&lt; HTTP/1.1 404 Not Found
-% curl -v -s --header &#39;User-Agent:Opera/12.0&#39; https://www.oep.no/pub/report.xhtml?reportId=3 2&gt;&amp;1 |grep &#39;&lt; HTTP&#39;
-&lt; HTTP/1.1 200 OK
-%
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;Her kan en se at tjenesten gir «404 Not Found» for curl i
-standardoppsettet, mens den gir «200 OK» hvis curl hevder å være Opera
-versjon 12.0.  Offentlig elektronisk postjournal startet blokkeringen
-2017-03-02.&lt;/p&gt;
-
-&lt;p&gt;Blokkeringen vil gjøre det litt vanskeligere å maskinelt hente
-informasjon fra oep.no.  Kan blokkeringen være gjort for å hindre
-automatisert innsamling av informasjon fra OEP, slik Pressens
-Offentlighetsutvalg gjorde for å dokumentere hvordan departementene
-hindrer innsyn i
-&lt;a href=&quot;http://presse.no/dette-mener-np/undergraver-offentlighetsloven/&quot;&gt;rapporten
-«Slik hindrer departementer innsyn» som ble publiserte i januar
-2017&lt;/a&gt;.  Det virker usannsynlig, da det jo er trivielt å bytte
-User-Agent til noe nytt.&lt;/p&gt;
-
-&lt;p&gt;Finnes det juridisk grunnlag for det offentlige å diskriminere
-webklienter slik det gjøres her?  Der tilgang gis eller ikke alt etter
-hva klienten sier at den heter?  Da OEP eies av DIFI og driftes av
-Basefarm, finnes det kanskje noen dokumenter sendt mellom disse to
-aktørene man kan be om innsyn i for å forstå hva som har skjedd.  Men
-&lt;a href=&quot;https://www.oep.no/search/result.html?period=dateRange&amp;fromDate=01.01.2016&amp;toDate=01.04.2017&amp;dateType=documentDate&amp;caseDescription=&amp;descType=both&amp;caseNumber=&amp;documentNumber=&amp;sender=basefarm&amp;senderType=both&amp;documentType=all&amp;legalAuthority=&amp;archiveCode=&amp;list2=196&amp;searchType=advanced&amp;Search=Search+in+records&quot;&gt;postjournalen
-til DIFI viser kun to dokumenter&lt;/a&gt; det siste året mellom DIFI og
-Basefarm.
-&lt;a href=&quot;https://www.mimesbronn.no/request/blokkering_av_tilgang_til_oep_fo&quot;&gt;Mimes brønn neste&lt;/a&gt;,
-tenker jeg.&lt;/p&gt;

+               <description>&lt;p&gt;I &lt;a href=&quot;https://no.wikipedia.org/wiki/VHS&quot;&gt;VHS-kassettenes&lt;/a&gt;
+tid var det rett frem å ta vare på et TV-program en ønsket å kunne se
+senere, uten å være avhengig av at programmet ble sendt på nytt.
+Kanskje ønsket en å se programmet på hytten der det ikke var
+TV-signal, eller av andre grunner ha det tilgjengelig for fremtidig
+fornøyelse.  Dette er blitt vanskeligere med introduksjon av
+digital-TV og webstreaming, der opptak til harddisk er utenfor de
+flestes kontroll hvis de bruker ufri programvare og bokser kontrollert
+av andre.  Men for NRK her i Norge, finnes det heldigvis flere fri
+programvare-alternativer, som jeg har
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Hvordan_enkelt_laste_ned_filmer_fra_NRK.html&quot;&gt;skrevet&lt;/a&gt;
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Hvordan_enkelt_laste_ned_filmer_fra_NRK_med_den__nye__l_sningen.html&quot;&gt;om&lt;/a&gt;
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Nedlasting_fra_NRK__som_Matroska_med_undertekster.html&quot;&gt;før&lt;/a&gt;.
+Så lenge kilden for nedlastingen er lovlig lagt ut på nett (hvilket
+jeg antar NRK gjør), så er slik lagring til privat bruk også lovlig i
+Norge.&lt;/p&gt;
+
+&lt;p&gt;Sist jeg så på saken, i 2016, nevnte jeg at
+&lt;a href=&quot;https://rg3.github.com/youtube-dl/&quot;&gt;youtube-dl&lt;/a&gt; ikke kunne
+bake undertekster fra NRK inn i videofilene, og at jeg derfor
+foretrakk andre alternativer.  Nylig oppdaget jeg at dette har endret
+seg.  Fordelen med youtube-dl er at den er tilgjengelig direkte fra
+Linux-distribusjoner som &lt;a href=&quot;https://www.debian.org/&quot;&gt;Debian&lt;/a&gt;
+og &lt;a href=&quot;https://www.ubuntu.com/&quot;&gt;Ubuntu&lt;/a&gt;, slik at en slipper å
+finne ut selv hvordan en skal få dem til å virke.&lt;/p&gt;
+
+&lt;p&gt;For å laste ned et NRK-innslag med undertekster, og få den norske
+underteksten pakket inn i videofilen, så kan følgende kommando
+brukes:&lt;/p&gt;
+
+&lt;p&gt;&lt;pre&gt;
+youtube-dl --write-sub --sub-format ttml \
+  --convert-subtitles srt --embed-subs \
+  https://tv.nrk.no/serie/ramm-ferdig-gaa/MUHU11000316/27-04-2018
+&lt;/pre&gt;&lt;/p&gt;
+
+&lt;p&gt;URL-eksemplet er dagens toppsak på tv.nrk.no.  Resultatet er en
+MP4-fil med filmen og undertekster som kan spilles av med VLC.  Merk
+at VLC ikke viser frem undertekster før du aktiverer dem.  For å gjøre
+det, høyreklikk med musa i fremviservinduet, velg menyvalget for
+undertekst og så norsk språk.  Jeg testet også &#39;--write-auto-sub&#39;,
+men det kommandolinjeargumentet ser ikke ut til å fungere, så jeg
+endte opp med settet med argumentlisten over, som jeg fant i en
+feilrapport i youtube-dl-prosjektets samling over feilrapporter.&lt;/p&gt;
+
+&lt;p&gt;Denne støtten i youtube-dl gjør det svært enkelt å lagre
+NRK-innslag, det være seg nyheter, filmer, serier eller dokumentater,
+for å ha dem tilgjengelig for fremtidig referanse og bruk, uavhengig
+av hvor lenge innslagene ligger tilgjengelig hos NRK.  Så får det ikke
+hjelpe at NRKs jurister mener at det er
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Best___ikke_fortelle_noen_at_streaming_er_nedlasting___.html&quot;&gt;vesensforskjellig
+å legge tilgjengelig for nedlasting og for streaming&lt;/a&gt;, når det rent
+teknisk er samme sak.&lt;/p&gt;
+
+&lt;p&gt;Programmet youtube-dl støtter også en rekke andre nettsteder, se
+prosjektoversikten for
+&lt;a href=&quot;http://rg3.github.io/youtube-dl/supportedsites.html&quot;&gt;en
+komplett liste&lt;/a&gt;.&lt;/p&gt;

-                <pubDate>Sun, 19 Mar 2017 08:00:00 +0100</pubDate>
-               <description>&lt;p&gt;The &lt;a href=&quot;https://github.com/hiOA-ABI/nikita-noark5-core&quot;&gt;Nikita
-Noark 5 core project&lt;/a&gt; is implementing the Norwegian standard for
-keeping an electronic archive of government documents.
-&lt;a href=&quot;http://www.arkivverket.no/arkivverket/Offentlig-forvaltning/Noark/Noark-5/English-version&quot;&gt;The
-Noark 5 standard&lt;/a&gt; document the requirement for data systems used by
-the archives in the Norwegian government, and the Noark 5 web interface
-specification document a REST web service for storing, searching and
-retrieving documents and metadata in such archive.  I&#39;ve been involved
-in the project since a few weeks before Christmas, when the Norwegian
-Unix User Group
-&lt;a href=&quot;https://www.nuug.no/news/NOARK5_kjerne_som_fri_programvare_f_r_epostliste_hos_NUUG.shtml&quot;&gt;announced
-it supported the project&lt;/a&gt;.  I believe this is an important project,
-and hope it can make it possible for the government archives in the
-future to use free software to keep the archives we citizens depend
-on.  But as I do not hold such archive myself, personally my first use
-case is to store and analyse public mail journal metadata published
-from the government.  I find it useful to have a clear use case in
-mind when developing, to make sure the system scratches one of my
-itches.&lt;/p&gt;
-
-&lt;p&gt;If you would like to help make sure there is a free software
-alternatives for the archives, please join our IRC channel
-(&lt;a href=&quot;irc://irc.freenode.net/%23nikita&quot;&quot;&gt;#nikita on
-irc.freenode.net&lt;/a&gt;) and
-&lt;a href=&quot;https://lists.nuug.no/mailman/listinfo/nikita-noark&quot;&gt;the
-project mailing list&lt;/a&gt;.&lt;/p&gt;
-
-&lt;p&gt;When I got involved, the web service could store metadata about
-documents.  But a few weeks ago, a new milestone was reached when it
-became possible to store full text documents too.  Yesterday, I
-completed an implementation of a command line tool
-&lt;tt&gt;archive-pdf&lt;/tt&gt; to upload a PDF file to the archive using this
-API.  The tool is very simple at the moment, and find existing
-&lt;a href=&quot;https://en.wikipedia.org/wiki/Fonds&quot;&gt;fonds&lt;/a&gt;, series and
-files while asking the user to select which one to use if more than
-one exist.  Once a file is identified, the PDF is associated with the
-file and uploaded, using the title extracted from the PDF itself.  The
-process is fairly similar to visiting the archive, opening a cabinet,
-locating a file and storing a piece of paper in the archive.  Here is
-a test run directly after populating the database with test data using
-our API tester:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
-~/src//noark5-tester$ ./archive-pdf mangelmelding/mangler.pdf
-using arkiv: Title of the test fonds created 2017-03-18T23:49:32.103446
-using arkivdel: Title of the test series created 2017-03-18T23:49:32.103446
-
- 0 - Title of the test case file created 2017-03-18T23:49:32.103446
- 1 - Title of the test file created 2017-03-18T23:49:32.103446
-Select which mappe you want (or search term): 0
-Uploading mangelmelding/mangler.pdf
-  PDF title: Mangler i spesifikasjonsdokumentet for NOARK 5 Tjenestegrensesnitt
-  File 2017/1: Title of the test case file created 2017-03-18T23:49:32.103446
-~/src//noark5-tester$
-&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;You can see here how the fonds (arkiv) and serie (arkivdel) only had
-one option, while the user need to choose which file (mappe) to use
-among the two created by the API tester.  The &lt;tt&gt;archive-pdf&lt;/tt&gt;
-tool can be found in the git repository for the API tester.&lt;/p&gt;
-
-&lt;p&gt;In the project, I have been mostly working on
-&lt;a href=&quot;https://github.com/petterreinholdtsen/noark5-tester&quot;&gt;the API
-tester&lt;/a&gt; so far, while getting to know the code base.  The API
-tester currently use
-&lt;a href=&quot;https://en.wikipedia.org/wiki/HATEOAS&quot;&gt;the HATEOAS links&lt;/a&gt;
-to traverse the entire exposed service API and verify that the exposed
-operations and objects match the specification, as well as trying to
-create objects holding metadata and uploading a simple XML file to
-store.  The tester has proved very useful for finding flaws in our
-implementation, as well as flaws in the reference site and the
-specification.&lt;/p&gt;
-
-&lt;p&gt;The test document I uploaded is a summary of all the specification
-defects we have collected so far while implementing the web service.
-There are several unclear and conflicting parts of the specification,
-and we have
-&lt;a href=&quot;https://github.com/petterreinholdtsen/noark5-tester/tree/master/mangelmelding&quot;&gt;started
-writing down&lt;/a&gt; the questions we get from implementing it.  We use a
-format inspired by how &lt;a href=&quot;http://www.opengroup.org/austin/&quot;&gt;The
-Austin Group&lt;/a&gt; collect defect reports for the POSIX standard with
-&lt;a href=&quot;http://www.opengroup.org/austin/mantis.html&quot;&gt;their
-instructions for the MANTIS defect tracker system&lt;/a&gt;, in lack of an official way to structure defect reports for Noark 5 (our first submitted defect report was a &lt;a href=&quot;https://github.com/petterreinholdtsen/noark5-tester/blob/master/mangelmelding/sendt/2017-03-15-mangel-prosess.md&quot;&gt;request for a procedure for submitting defect reports&lt;/a&gt; :).
-
-&lt;p&gt;The Nikita project is implemented using Java and Spring, and is
-fairly easy to get up and running using Docker containers for those
-that want to test the current code base.  The API tester is
-implemented in Python.&lt;/p&gt;

+melder i dag at flertallet i Familie- og kulturkomiteen på Stortinget
+har bestemt seg for å introdusere en ny sensurinfrastruktur i Norge.
+Fra før har Norge en «frivillig» sensurinfrastruktur basert på
+DNS-navn, der de største ISP-ene basert på en liste med DNS-navn
+forgifter DNS-svar og omdirigerer til et annet IP-nummer enn det som
+ligger i DNS.  Nå kommer altså IP-basert omdirigering i tillegg.  Når
+infrastrukturen er på plass, er sensur av IP-adresser redusert et
+spørsmål om hvilke IP-nummer som skal blokkeres.  Listen over
+IP-adresser vil naturligvis endre seg etter hvert som myndighetene
+endrer seg.  Det er ingen betryggende tanke.&lt;/p&gt;

+               <description>&lt;p&gt;Brevpost er beskyttet av straffelovens bestemmelse som gjør det
+kriminelt å åpne andres brev.  Dette følger av (ny) straffelovs
+&lt;a href=&quot;https://lovdata.no/dokument/NL/lov/2005-05-20-28/§205&quot;&gt;§ 205
+(Krenkelse av retten til privat kommunikasjon)&lt;/a&gt;, som sier at «Med
+bot eller fengsel inntil 2 år straffes den som uberettiget ...  c)
+åpner brev eller annen lukket skriftlig meddelelse som er adressert
+til en annen, eller på annen måte skaffer seg uberettiget tilgang til
+innholdet.» Dette gjelder såvel postbud som alle andre som har
+befatning med brevet etter at avsender har befatning med et lukket
+brev. Tilsvarende står også tidligere utgaver av den norske
+straffeloven.&lt;/p&gt;
+
+&lt;p&gt;Når en registrerer seg på usikre digitale postkasseløsningene, som
+f.eks. Digipost og e-Boks, og slik tar disse i bruk, så gir en de som
+står bak løsningene tillatelse til å åpne sine brev.  Dette er
+nødvendig for at innholdet i digital post skal kunne vises frem til
+mottaker via tjenestens websider.  Dermed gjelder ikke straffelovens
+paragraf om forbud mot å åpne brev, da tilgangen ikke lenger er
+uberettiget.  En gir altså fremmede tilgang til å lese sin
+korrespondanse.  I tillegg vil bruk av slike usikre digitale
+postbokser føre til at det blir registrert når du leser brevene, hvor
+du befinner deg (vha. tilkoblingens IP-adresse), hvilket utstyr du
+bruker og en rekke annen personlig informasjon som ikke er
+tilgjengelig når papirpost brukes.  Jeg foretrekker at det er
+lovmessig beskyttelse av min korrespondanse, som jo inneholder privat
+og personlig informasjon.  Det bidrar til litt bedre vern av personlig
+integritet i dagens norske samfunn.&lt;/p&gt;

-               <description>&lt;p&gt;Over the years, administrating thousand of NFS mounting linux
-computers at the time, I often needed a way to detect if the machine
-was experiencing NFS hang.  If you try to use &lt;tt&gt;df&lt;/tt&gt; or look at a
-file or directory affected by the hang, the process (and possibly the
-shell) will hang too.  So you want to be able to detect this without
-risking the detection process getting stuck too.  It has not been
-obvious how to do this.  When the hang has lasted a while, it is
-possible to find messages like these in dmesg:&lt;/p&gt;

+               <description>&lt;p&gt;The leaders of the worlds have started to congratulate the
+re-elected Russian head of state, and this causes some criticism.  I
+am though a little fascinated by a comment from USA senator John McCain,
+&lt;a href=&quot;http://thehill.com/homenews/senate/379339-mccain-rips-trumps-congratulatory-call-to-putin-as-insult-to-russian-people&quot;&gt;sited
+by The Hill and others&lt;/a&gt;:

 
 &lt;p&gt;&lt;blockquote&gt;
 
 &lt;p&gt;&lt;blockquote&gt;

-nfs: server nfsserver not responding, still trying
-&lt;br&gt;nfs: server nfsserver OK
+&lt;p&gt;&quot;An American president does not lead the Free World by
+congratulating dictators on winning sham elections.&quot;&lt;/p&gt;

 &lt;/blockquote&gt;&lt;/p&gt;
 &lt;/blockquote&gt;&lt;/p&gt;

-  
-&lt;p&gt;It is hard to know if the hang is still going on, and it is hard to
-be sure looking in dmesg is going to work.  If there are lots of other
-messages in dmesg the lines might have rotated out of site before they
-are noticed.&lt;/p&gt;
-
-&lt;p&gt;While reading through the nfs client implementation in linux kernel
-code, I came across some statistics that seem to give a way to detect
-it.  The om_timeouts sunrpc value in the kernel will increase every
-time the above log entry is inserted into dmesg.  And after digging a
-bit further, I discovered that this value show up in
-/proc/self/mountstats on Linux.&lt;/p&gt;
-
-&lt;p&gt;The mountstats content seem to be shared between files using the
-same file system context, so it is enough to check one of the
-mountstats files to get the state of the mount point for the machine.
-I assume this will not show lazy umounted NFS points, nor NFS mount
-points in a different process context (ie with a different filesystem
-view), but that does not worry me.&lt;/p&gt;
-
-&lt;p&gt;The content for a NFS mount point look similar to this:&lt;/p&gt;

 
 

-&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
-[...]

+&lt;p&gt;While I totally agree with the senator here, the way the quote is
+phrased make me suspect that he is unaware of the simple fact that USA
+have not lead the Free World since at least before its government
+&lt;a href=&quot;https://en.wikipedia.org/wiki/Maher_Arar&quot;&gt;kidnapped a
+completely innocent Canadian citizen in transit on his way home to
+Canada via John F. Kennedy International Airport in September 2002 and
+sent him to be tortured in Syria for a year&lt;/a&gt;.&lt;/p&gt;

 
 

-&lt;p&gt;The key number to look at is the third number in the per-op list.
-It is the number of NFS timeouts experiences per file system
-operation.  Here 22 write timeouts and 5 access timeouts.  If these
-numbers are increasing, I believe the machine is experiencing NFS
-hang.  Unfortunately the timeout value do not start to increase right
-away.  The NFS operations need to time out first, and this can take a
-while.  The exact timeout value depend on the setup.  For example the
-defaults for TCP and UDP mount points are quite different, and the
-timeout value is affected by the soft, hard, timeo and retrans NFS
-mount options.&lt;/p&gt;
-
-&lt;p&gt;The only way I have been able to get working on Debian and RedHat
-Enterprise Linux for getting the timeout count is to peek in /proc/.
-But according to
-&lt;ahref=&quot;http://docs.oracle.com/cd/E19253-01/816-4555/netmonitor-12/index.html&quot;&gt;Solaris
-10 System Administration Guide: Network Services&lt;/a&gt;, the &#39;nfsstat -c&#39;
-command can be used to get these timeout values.  But this do not work
-on Linux, as far as I can tell.  I
-&lt;ahref=&quot;http://bugs.debian.org/857043&quot;&gt;asked Debian about this&lt;/a&gt;,
-but have not seen any replies yet.&lt;/p&gt;
-
-&lt;p&gt;Is there a better way to figure out if a Linux NFS client is
-experiencing NFS hangs?  Is there a way to detect which processes are
-affected?  Is there a way to get the NFS mount going quickly once the
-network problem causing the NFS hang has been cleared?  I would very
-much welcome some clues, as we regularly run into NFS hangs.&lt;/p&gt;
+&lt;p&gt;USA might be running ahead, but the path they are taking is not the
+one taken by any Free World.&lt;/p&gt;

+               <description>&lt;p&gt;So, Cambridge Analytica is getting some well deserved criticism for
+(mis)using information it got from Facebook about 50 million people,
+mostly in the USA.  What I find a bit surprising, is how little
+criticism Facebook is getting for handing the information over to
+Cambridge Analytica and others in the first place.  And what about the
+people handing their private and personal information to Facebook?
+And last, but not least, what about the government offices who are
+handing information about the visitors of their web pages to Facebook?
+No-one who looked at the terms of use of Facebook should be surprised
+that information about peoples interests, political views, personal
+lifes and whereabouts would be sold by Facebook.&lt;/p&gt;
+
+&lt;p&gt;What I find to be the real scandal is the fact that Facebook is
+selling your personal information, not that one of the buyers used it
+in a way Facebook did not approve when exposed.  It is well known that
+Facebook is selling out their users privacy, but a scandal
+nevertheless.  Of course the information provided to them by Facebook
+would be misused by one of the parties given access to personal
+information about the millions of Facebook users.  Collected
+information will be misused sooner or later.  The only way to avoid
+such misuse, is to not collect the information in the first place.  If
+you do not want Facebook to hand out information about yourself for
+the use and misuse of its customers, do not give Facebook the
+information.&lt;/p&gt;
+
+&lt;p&gt;Personally, I would recommend to completely remove your Facebook
+account, and take back some control of your personal information.
+&lt;a href=&quot;https://www.theguardian.com/technology/2018/mar/19/how-to-protect-your-facebook-privacy-or-delete-yourself-completely&quot;&gt;According
+to The Guardian&lt;/a&gt;, it is a bit hard to find out how to request
+account removal (and not just &#39;disabling&#39;).  You need to
+&lt;a href=&quot;https://www.facebook.com/help/224562897555674?helpref=faq_content&quot;&gt;visit
+a specific Facebook page&lt;/a&gt; and click on &#39;let us know&#39; on that page
+to get to &lt;a href=&quot;https://www.facebook.com/help/delete_account&quot;&gt;the
+real account deletion screen&lt;/a&gt;.  Perhaps something to consider?  I
+would not trust the information to really be deleted (who knows,
+perhaps NSA, GCHQ and FRA already got a copy), but it might reduce the
+exposure a bit.&lt;/p&gt;
+
+&lt;p&gt;If you want to learn more about the capabilities of Cambridge
+Analytica, I recommend to see the video recording of the one hour talk
+Paul-Olivier Dehaye gave to &lt;a href=&quot;&quot;&gt;NUUG&lt;/a&gt; last april about
+&lt;a href=&quot;https://www.nuug.no/aktiviteter/20170404-big-data-psychometric/&quot;&gt;
+Data collection, psychometric profiling and their impact on
+politics&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;And if you want to communicate with your friends and loved ones,
+use some end-to-end encrypted method like
+&lt;a href=&quot;https://www.signal.org/&quot;&gt;Signal&lt;/a&gt; or
+&lt;a href=&quot;https://ring.cx/&quot;&gt;Ring&lt;/a&gt;, and stop sharing your private
+messages with strangers like Facebook and Google.&lt;/p&gt;
