+ <div class="date">13th August 2018</div>
+ <div class="body"><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>

+ <div class="body"><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>

+ <div class="date">31st July 2018</div>
+ <div class="body"><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
+<enclosure> 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>

+<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>

-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.</p>
-
-<p>Sist jeg så på saken, i 2016, nevnte jeg at
-<a href="https://rg3.github.com/youtube-dl/">youtube-dl</a> ikke kunne
-bake undertekster fra NRK inn i videofilene, og at jeg derfor
-foretrakk andre alternativer. Nylig oppdaget jeg at dette har endret

-Linux-distribusjoner som <a href="https://www.debian.org/">Debian</a>
-og <a href="https://www.ubuntu.com/">Ubuntu</a>, slik at en slipper å
-finne ut selv hvordan en skal få dem til å virke.</p>
-

-
-<p>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 '--write-auto-sub',
-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.</p>
-
-<p>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

-(Krenkelse av retten til privat kommunikasjon)</a>, 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.</p>
-
-<p>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.</p>

- <div class="body"><p>The leaders of the worlds have started to congratulate the

-am though a little fascinated by a comment from USA senator John McCain,
-<a href="http://thehill.com/homenews/senate/379339-mccain-rips-trumps-congratulatory-call-to-putin-as-insult-to-russian-people">sited

-
-<p><blockquote>
-<p>"An American president does not lead the Free World by

-</blockquote></p>
-
-<p>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

- <div class="date">21st March 2018</div>
- <div class="body"><p>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.</p>
-
-<p>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.</p>
-
-<p>Personally, I would recommend to completely remove your Facebook
-account, and take back some control of your personal information.
-<a href="https://www.theguardian.com/technology/2018/mar/19/how-to-protect-your-facebook-privacy-or-delete-yourself-completely">According
-to The Guardian</a>, it is a bit hard to find out how to request
-account removal (and not just 'disabling'). You need to
-<a href="https://www.facebook.com/help/224562897555674?helpref=faq_content">visit
-a specific Facebook page</a> and click on 'let us know' on that page
-to get to <a href="https://www.facebook.com/help/delete_account">the
-real account deletion screen</a>. 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.</p>
-
-<p>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 <a href="">NUUG</a> last april about
-<a href="https://www.nuug.no/aktiviteter/20170404-big-data-psychometric/">
-Data collection, psychometric profiling and their impact on
-politics</a>.</p>
-
-<p>And if you want to communicate with your friends and loved ones,
-use some end-to-end encrypted method like
-<a href="https://www.signal.org/">Signal</a> or
-<a href="https://ring.cx/">Ring</a>, and stop sharing your private
-messages with strangers like Facebook and Google.</p>
