- <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><p>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'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
-<a href="https://github.com/Freeyourgadget/Gadgetbridge/">Gadgetbridge</a>.
-It provide cloudless collection and storing of data from a variety of
-trackers. Its
-<a href="https://github.com/Freeyourgadget/Gadgetbridge/#supported-devices">list
-of supported devices</a> 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
-<a href="https://us.amazfit.com/shop/bip?variant=336750">Amazfit
-Bip</a> and
-<a href="http://www.xiaomimi6phone.com/xiaomi-mi-band-3-features-release-date-rumors/">Xiaomi
-Band 3</a>.</p>
-
-<p>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
-<a href="https://www.gpsbabel.org/htmldoc-development/fmt_garmin_fit.html">Garmin
-FIT files</a> containing the collected measurements. While
-proprietary, FIT files apparently can be read at least by
-<a href="https://www.gpsbabel.org">GPSBabel</a> and the
-<a href="https://apps.nextcloud.com/apps/gpxpod">GpxPod</a> 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
-<a href="https://buy.garmin.com/en-US/US/p/564291">Garmin Forerunner
-935</a>, 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.</p>
-
-<p>A final idea was to build ones own unit, perhaps by basing it on a
-wearable hardware platforms like
-<a href="https://learn.adafruit.com/flora-geo-watch">the Flora Geo
-Watch</a>. 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.</p>
-
-<p>While I was working on tracking down links, I came across an
-inspiring TED talk by Dave Debronkart about
-<a href="https://archive.org/details/DavedeBronkart_2010X">being a
-e-patient</a>, and discovered the web site
-<a href="https://participatorymedicine.org/epatients/">Participatory
-Medicine</a>. 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.</p>

+ <description><p>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 <a href="https://en.wikipedia.org/wiki/Loren_Eiseley">Loren
+Eiseley</a> <a href="https://en.wikipedia.org/wiki/The_Star_Thrower">i
+flere ulike varianter</a>. På norsk tror jeg den går under navnet
+«Gutten og sjøstjernen», og jeg fant en oversettelse av en utgave av den
+hos
+<a href="https://no.quora.com/Hva-er-din-favoritthistorie">Quora</a>.
+Fant også <a href="https://www.youtube.com/watch?v=-qClChUdlfI">en
+filmatisering</a>, men den versjonen jeg liker best fant jeg
+<a href="https://www.goodreads.com/author/quotes/56782.Loren_Eiseley">hos
+Goodreads</a>. Jeg oversatte den utgaven til norsk i går, og har lyst
+til å dele den med deg:
+
+<blockquote><p>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.</p>
+
+<p>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.</p>

- <description><p>Dear lazyweb,</p>
-
-<p>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 <strong>only</strong> 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 "the cloud"). The collected data should be available
-using only free software. I'm not interested in depending on some
-non-free software that will leave me high and dry some time in the
-future. I'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 "cloud enabled").
-Is there an alternative? I'm not interested in giving money to people
-requiring me to accept "privacy terms" to allow myself to measure my
-own health.</p>

- <title>Sharing images with friends and family using RSS and EXIF/XMP metadata</title>

- <description><p>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
-&lt;enclosure&gt; RSS tag), but was unable to find a current supplier
-of such frames. In the end I gave up that approach.</p>
-
-<p>Some months ago, I discovered that
-<a href="https://www.jwz.org/xscreensaver/">XScreensaver</a> 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
-<a href="https://kodi.tv">Kodi</a> (both using
-<a href="https://www.openelec.tv/">OpenELEC</a> and
-<a href="https://libreelec.tv">LibreELEC</a>) provide the
-<a href="https://github.com/grinsted/script.screensaver.feedreader">Feedreader</a>
-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.</p>
-
-<p>Armed with motivation and a test photo frame, I set out to generate
-a RSS feed for the Kodi instance. I adjusted my <a
-href="https://freedombox.org/">Freedombox</a> 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.</p>
-
-<p>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:</p>
-
-<blockquote><pre>
-exiftool -headline='The RSS image title' \
- -description='The RSS image description.' \
- -subject+=for-family photo.jpeg
-</pre></blockquote>
-
-<p>I initially tried the "-title" and "keyword" tags, but they were
-invisible in digiKam, so I changed to "-headline" and "-subject". I
-use the keyword/subject 'for-family' 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.</p>
-
-<p>Are there better ways to do this? Get in touch if you have better
-suggestions.</p>

+ <description><p>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:</p>
+
+<blockquote>

+<br>Subject: When terms of use turn users away
+<br>To: [contact@some.site]
+<br>Date: Sat, 07 Dec 2019 16:30:56 +0100
+
+<p>Dear [Site Owner],</p>
+
+<p>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 &lt;URL:
+https://www.[some.site]/terms-of-use &gt; and &lt;URL:
+https://www.[some.site]/privacy-policy &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.</p>
+
+<p>--
+<br>Happy hacking
+<br>Petter Reinholdtsen</p>
+</blockquote>
+
+<p>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...</p>

- <title>Simple streaming the Linux desktop to Kodi using GStreamer and RTP</title>

- <description><p>Last night, I wrote
-<a href="http://people.skolelinux.org/pere/blog/Streaming_the_Linux_desktop_to_Kodi_using_VLC_and_RTSP.html">a
-recipe to stream a Linux desktop using VLC to a instance of Kodi</a>.
-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.</p>
-
-<p>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
-<a href="https://kodi.wiki/view/JSON-RPC_API/v8">the JSON-RPC API in
-Kodi</a> 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.</p>

+ <description><p>Four years ago, I did a back of the envelope calculation on
+<a href="http://people.skolelinux.org/pere/blog/What_would_it_cost_to_store_all_phone_calls_in_Norway_.html">how
+much it would cost to store audio recordings of all the phone calls in
+Norway</a>, 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.</p>
+
+<p>The number of phone call minutes for 2018 was fetched from
+<a href="https://ekomstatistikken.nkom.no/">the NKOM statistics
+site</a>, 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.</p>

+<p>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.</p>
+
+<p>So, with the parameters in place, lets update the old table
+estimating cost for calls in a given year:</p>
+
+<table border="1">
+<tr><th>Year</th><th>Call minutes</th><th>Size</th><th>Price in NOK / EUR</th></tr>
+<tr><td>2005</td><td align="right">24 000 000 000</td><td align="right">1.3 PiB</td><td align="right">1 170 000 / 117 000</td></tr>
+
+<tr><td>2012</td><td align="right">18 000 000 000</td><td align="right">1.0 PiB</td><td align="right">900 000 / 90 000</td></tr>
+
+<tr><td>2013</td><td align="right">17 000 000 000</td><td align="right">950 TiB</td><td align="right">855 000 / 85 500</td></tr>
+
+<tr><td>2018</td><td align="right">7 976 244 000</td><td align="right">445 TiB</td><td align="right">401 100 / 40 110</td></tr>
+</table>
+
+<p>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.</p>

- <pubDate>Thu, 12 Jul 2018 02:00:00 +0200</pubDate>
- <description><p>PS: See
-<ahref="http://people.skolelinux.org/pere/blog/Simple_streaming_the_Linux_desktop_to_Kodi_using_GStreamer_and_RTP.html">the
-followup post</a> for a even better approach.</p>
-
-<p>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.</p>
-
-<p>I had a look at several approaches, for example
-<a href="https://github.com/mfoetsch/dlna_live_streaming">using uPnP
-DLNA as described in 2011</a>, 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.</p>
-
-<p>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.</p>
-
-<p>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.</p>
-
-<p>I did not spend much time investigating codeces. I combined the
-rtp and rtsp recipes from
-<a href="https://wiki.videolan.org/Documentation:Streaming_HowTo/Command_Line_Examples/">the
-VLC Streaming HowTo/Command Line Examples</a>, and was able to get
-this working on the desktop/streaming end.</p>
-
-<blockquote><pre>
-vlc screen:// --sout \
- '#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:rtp{dst=projector.local,port=1234,sdp=rtsp://192.168.11.4:8080/test.sdp}'
-</pre></blockquote>
-
-<p>I ssh-ed into my Kodi box and created a file like this with the
-same IP address:</p>
-
-<blockquote><pre>
-echo rtsp://192.168.11.4:8080/test.sdp \
- > /storage/videos/screenstream.m3u
-</pre></blockquote>
-
-<p>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. :)</p>
-
-<p>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.</p>
-
-<p><strong>Update 2018-07-12</strong>: Johannes Schauer send me a few
-succestions and reminded me about an important step. The "screen:"
-input source is only available once the vlc-plugin-access-extra
-package is installed on Debian. Without it, you will see this error
-message: "VLC is unable to open the MRL 'screen://'. Check the log
-for details." 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
-
-<blockquote><pre>
-cvlc screen:// --sout \
- '#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:rtp{sdp=rtsp://:8080/}'
-</pre></blockquote>
-
-<p>and this on the Kodi end<p>
-
-<blockquote><pre>
-echo rtsp://192.168.11.4:8080/ \
- > /storage/videos/screenstream.m3u
-</pre></blockquote>
-
-<p>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've tried to change the vb and ab
-parameters to use more bandwidth, but it did not make a
-difference.</p>
-
-<p>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:
-
-<blockquote><pre>
-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=$(pactl list | grep -A2 'Source #' | \
- grep 'Name: .*\.monitor$' | cut -d" " -f2|head -1) ! \
- audioconvert ! queue2 ! avenc_aac ! queue2 ! mux.
-</pre></blockquote>
-
-<p>and this on the Kodi end<p>
-
-<blockquote><pre>
-echo udp://@239.255.0.1:1234 \
- > /storage/videos/screenstream.m3u
-</pre></blockquote>
-
-<p>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 "hop" for each increase (read up on
-multicast to learn more. :)!</p>
-
-<p>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.</p>
-
-<blockquote><pre>
-cvlc screen:// --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:rtp{mux=ts,dst=239.255.0.1,port=1234,sdp=sap}'

+ <description><p>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've been able to identify some of
+them, but for some it is hard to figure out when they died.</p>
+
+</p>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.</p>

-
-<p>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 "file --mime &lt;filename&gt;", and then
-look up all packages announcing support for this format in their
-AppStream metadata (XML or .desktop file) using "appstreamcli
-what-provides mimetype &lt;mime-type&gt;. For example if you, like
-me, want to know which packages support inode/directory, you can get a
-list like this:</p>
-
-<p><blockquote><pre>
-% 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: pcmanfm
-Package: pcmanfm-qt
-Package: qweborf
-Package: ranger
-Package: sirikali
-Package: spacefm
-Package: spacefm
-Package: vifm
-%
-</pre></blockquote></p>
-
-<p>Using the same method, I can quickly discover that the Sketchup file
-format is not yet supported by any package in Debian:</p>
-
-<p><blockquote><pre>
-% appstreamcli what-provides mimetype application/vnd.sketchup.skp
-Could not find component providing 'mimetype::application/vnd.sketchup.skp'.
-%
-</pre></blockquote></p>
-
-<p>Yesterday I used it to figure out which packages support the STL 3D
-format:</p>
-
-<p><blockquote><pre>
-% appstreamcli what-provides mimetype application/sla|grep Package
-Package: cura
-Package: meshlab
-Package: printrun
-%
-</pre></blockquote></p>
-
-<p>PS: A new version of Cura was uploaded to Debian yesterday.</p>
+<p>Perhaps you can help me figuring death year of those missing it, or
+right holders if some are missing in IMDb? It would be nice to have a
+definite list of Norwegian movies that are legal to share on the
+Internet.</p>

- <description><p>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 'apt upgrade'. I normally
-would resolve the issue by doing 'apt install &lt;somepackages&gt;' 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 'apt-in-chunks':</p>
-
-<p><blockquote><pre>
-#!/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 [ "$1" ]; then
- grep -v "$1"
- else
- cat
- fi
-}
-
-for p in $(apt list --upgradable | ignore "$@" |cut -d/ -f1 | grep -v '^Listing...'); do
- echo "Upgrading $p"
- apt clean
- apt install --download-only -y $p
- for f in /var/cache/apt/archives/*.deb; do
- if [ -e "$f" ]; then
- dpkg -i /var/cache/apt/archives/*.deb
- break
- fi
- done
-done
-</pre></blockquote></p>
-
-<p>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
-'apt install -f' 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.</p>
-
-<p>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
-'ghc', but I have run into other large packages causing similar
-problems earlier (like TeX).</p>
-
-<p>Update 2018-07-08: Thanks to Paul Wise, I am aware of two
-alternative ways to handle this. The "unattended-upgrades
---minimal-upgrade-steps" 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, "aptutude upgrade" can upgrade single packages, thus avoiding
-the need for using "dpkg -i" in the script above.</p>

+books published in the USA that are now in the public domain</a>,
+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 <a href="https://retrofilmvault.com/">Retro Film
+Vault</a> 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.</p>
+
+<p>The new total is 16307 IMDB IDs (aka films) in the public domain or

- <description><p>So far, at least hydro-electric power, coal power, wind power,

-Norway, where
-<a href="https://www.bontrup.com/en/activities/raw-materials/bremanger-quarry/">the

-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

+ <description><p>Jeg er veldig glad for å kunne fortelle at i går ble ny versjon av
+<a href="https://www.arkivverket.no/forvaltning-og-utvikling/noark-standarden/noark-5/tjenestegrensesnitt-noark5">API-spesifikasjonen
+for Noark 5 Tjenestegrensesnitt</a> 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.</p>
+
+<p>Spesifikasjonen er
+<a href="https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/">tilgjengelig
+som markdown-filer i Arkivverkets github-prosjekt for dette</a>, og de
+aller fleste av forslagene til forbedringer fra oss som holder på med
+<a href="https://gitlab.com/OsloMet-ABI/nikita-noark5-core">Nikita-prosjektet</a>
+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.</p>
+
+<p>Ellers må jeg jo si at det var hyggelig å se at min forrige

+ <description><p>Childs need to learn how to guard their privacy too. To help them,
+<a href="https://edri.org/">European Digital Rights (EDRi)</a> created

+
+<p>The 24 page booklet titled Digital Defenders is
+<a href="https://edri.org/digital-defenders-help-kids-defend-their-privacy-around-europe">available
+in several languages</a>. Thanks to the valuable contributions from

- <title>Add-on to control the projector from within Kodi</title>

- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Add_on_to_control_the_projector_from_within_Kodi.html</guid>
- <pubDate>Tue, 26 Jun 2018 23:55:00 +0200</pubDate>
- <description><p>My movie playing setup involve <a href="https://kodi.tv/">Kodi</a>,
-<a href="https://openelec.tv">OpenELEC</a> (probably soon to be
-replaced with <a href="https://libreelec.tv/">LibreELEC</a>) 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, <a href="https://www.infocus.com/">InFocus</a>, 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
-<a href="https://github.com/petterreinholdtsen/infocus-projector-control">a
-small script to control the projector</a>. 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.</p>
-
-<p>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.</p>
-
-<p>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
-<a href="https://github.com/pyserial/pyserial">pyserial module</a> in
-the add-on. The long term solution is to make a "script" type
-pyserial module for Kodi, that can be pulled in as a dependency in
-Kodi. But until that in place, I embed it.</p>
-
-<p>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.
-
-<p>If this sound interesting to you, check out
-<a href="https://github.com/fredrik-eriksson/kodi_projcontrol">the
-project github repository</a>. 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.</p>
-
-<p>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.</p>

+ <description><p><em>av Thomas Sødring (OsloMet) og Petter Reinholdtsen (foreningen
+NUUG)</em></p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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:</p>
+
+<p><blockquote>
+.../sakarkiv/journalpost?filter=contains(tittel, 'nabovarsel')
+</blockquote></p>
+
+<p>Spørringen over vil hente en liste av alle dine journalposter der
+tittelen til journalposten inneholder ordet 'nabovarsel'. 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.</p>
+
+<p>Standardisering er viktig fordi det <em>kan</em> 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.</p>
+
+<p>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.</p>

+<p>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.</p>
+
+<p>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.</p>
+
+<p>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
+<a href="https://nikita.oslomet.no">https://nikita.oslomet.no</a> 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
+<a href="https://nikita.oslomet.no/browse.html">https://nikita.oslomet.no/browse.html</a>
+og der se hvordan API-et fungerer mer i detalj. Innloggingsdetaljer
+her er det samme som for brukergrensesnittet.</p>
+
+<p>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 "pakker", 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
+<a href="https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/pull/120">planlagt
+fjernet</a> 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.</p>
+
+<p>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
+<a href="https://webchat.freenode.net?channels=#nikita">https://webchat.freenode.net?channels=#nikita</a>),
+og har en e-postliste nikita-noark@nuug.no hos NUUG (tilgjengelig for
+påmelding og arkiv på
+<a href="https://lists.nuug.no/mailman/listinfo/nikita-noark">https://lists.nuug.no/mailman/listinfo/nikita-noark</a>)
+der en kan følge med eller være med oss på den spennende veien videre.
+Spesifikasjonen for Noark 5 Tjenestegrensesnitt vedlikeholdes på
