 105       <div class="date"> 8th October 2018</div>
 106       <div class="body"><p>I have  earlier covered the basics of trusted timestamping using the
 107 'openssl ts' client.  See blog post for
 108 <a href="http://people.skolelinux.org/pere/blog/Public_Trusted_Timestamping_services_for_everyone.html">2014</a>,
 109 <a href="http://people.skolelinux.org/pere/blog/syslog_trusted_timestamp___chain_of_trusted_timestamps_for_your_syslog.html">2016</a>
 110 and
 111 <a href="http://people.skolelinux.org/pere/blog/Idea_for_storing_trusted_timestamps_in_a_Noark_5_archive.html">2017</a>
 112 for those stories.  But some times I want to integrate the timestamping
 113 in other code, and recently I needed to integrate it into Python.
 114 After searching a bit, I found
 115 <a href="https://dev.entrouvert.org/projects/python-rfc3161">the
 116 rfc3161 library</a> which seemed like a good fit, but I soon
 117 discovered it only worked for python version 2, and I needed something
 118 that work with python version 3.  Luckily I next came across
 119 <a href="https://github.com/trbs/rfc3161ng/">the rfc3161ng library</a>,
 120 a fork of the original rfc3161 library.  Not only is it working with
 121 python 3, it have fixed a few of the bugs in the original library, and
 122 it has an active maintainer.  I decided to wrap it up and make it
 123 <a href="https://tracker.debian.org/pkg/python-rfc3161ng">available in
 124 Debian</a>, and a few days ago it entered Debian unstable and testing.</p>
 125
 126 <p>Using the library is fairly straight forward.  The only slightly
 127 problematic step is to fetch the required certificates to verify the
 128 timestamp.  For some services it is straight forward, while for others
 129 I have not yet figured out how to do it.  Here is a small standalone
 130 code example based on of the integration tests in the library code:</p>

 141 library, ie MIT/BSD.

 199 use.</p>

 217       <div class="date"> 4th October 2018</div>
 218       <div class="body"><p>A few days, I rescued a Windows victim over to Debian.  To try to
 219 rescue the remains, I helped set up automatic sync with Google Drive.
 220 I did not find any sensible Debian package handling this
 221 automatically, so I rebuild the grive2 source from
 222 <a href="http://www.webupd8.org/">the Ubuntu UPD8 PPA</a> to do the
 223 task and added a autostart desktop entry and a small shell script to
 224 run in the background while the user is logged in to do the sync.
 225 Here is a sketch of the setup for future reference.</p>
 226
 227 <p>I first created <tt>~/googledrive</tt>, entered the directory and
 228 ran '<tt>grive -a</tt>' to authenticate the machine/user.  Next, I
 229 created a autostart hook in <tt>~/.config/autostart/grive.desktop</tt>
 230 to start the sync when the user log in:</p>
 231
 232 <p><blockquote><pre>
 233 [Desktop Entry]
 234 Name=Google drive autosync
 235 Type=Application
 236 Exec=/home/user/bin/grive-sync
 237 </pre></blockquote></p>
 238
 239 <p>Finally, I wrote the <tt>~/bin/grive-sync</tt> script to sync
 240 ~/googledrive/ with the files in Google Drive.</p>
 241
 242 <p><blockquote><pre>
 243 #!/bin/sh
 244 set -e
 245 cd ~/
 246 cleanup() {
 247     if [ "$syncpid" ] ; then
 248         kill $syncpid
 249     fi
 250 }
 251 trap cleanup EXIT INT QUIT
 252 /usr/lib/grive/grive-sync.sh listen googledrive 2>&1 | sed "s%^%$0:%" &
 253 syncpdi=$!
 254 while true; do
 255     if ! xhost >/dev/null 2>&1 ; then
 256         echo "no DISPLAY, exiting as the user probably logged out"
 257         exit 1
 258     fi
 259     if [ ! -e /run/user/1000/grive-sync.sh_googledrive ] ; then
 260         /usr/lib/grive/grive-sync.sh sync googledrive
 261     fi
 262     sleep 300
 263 done 2>&1 | sed "s%^%$0:%"
 264 </pre></blockquote></p>
 265
 266 <p>Feel free to use the setup if you want.  It can be assumed to be
 267 GNU GPL v2 licensed (or any later version, at your leisure), but I
 268 doubt this code is possible to claim copyright on.</p>

 286       <div class="date">29th September 2018</div>
 287       <div class="body"><p>It would come as no surprise to anyone that I am interested in
 288 bitcoins and virtual currencies.  I've been keeping an eye on virtual
 289 currencies for many years, and it is part of the reason a few months
 290 ago, I started writing a python library for collecting currency
 291 exchange rates and trade on virtual currency exchanges.  I decided to
 292 name the end result valutakrambod, which perhaps can be translated to
 293 small currency shop.</p>
 294
 295 <p>The library uses the tornado python library to handle HTTP and
 296 websocket connections, and provide a asynchronous system for
 297 connecting to and tracking several services.  The code is available
 298 from
 299 <a href="http://github.com/petterreinholdtsen/valutakrambod">github</a>.</p>
 300
 301 </p>There are two example clients of the library.  One is very simple and
 302 list every updated buy/sell price received from the various services.
 303 This code is started by running bin/btc-rates and call the client code
 304 in valutakrambod/client.py.  The simple client look like this:</p>
 305
 306 <p><blockquote><pre>
 307 import functools
 308 import tornado.ioloop
 309 import valutakrambod
 310 class SimpleClient(object):
 311     def __init__(self):
 312         self.services = []
 313         self.streams = []
 314         pass
 315     def newdata(self, service, pair, changed):
 316         print("%-15s %s-%s: %8.3f %8.3f" % (
 317             service.servicename(),
 318             pair[0],
 319             pair[1],
 320             service.rates[pair]['ask'],
 321             service.rates[pair]['bid'])
 322         )
 323     async def refresh(self, service):
 324         await service.fetchRates(service.wantedpairs)
 325     def run(self):
 326         self.ioloop = tornado.ioloop.IOLoop.current()
 327         self.services = valutakrambod.service.knownServices()
 328         for e in self.services:
 329             service = e()
 330             service.subscribe(self.newdata)
 331             stream = service.websocket()
 332             if stream:
 333                 self.streams.append(stream)
 334             else:
 335                 # Fetch information from non-streaming services immediately
 336                 self.ioloop.call_later(len(self.services),
 337                                        functools.partial(self.refresh, service))
 338                 # as well as regularly
 339                 service.periodicUpdate(60)
 340         for stream in self.streams:
 341             stream.connect()
 342         try:
 343             self.ioloop.start()
 344         except KeyboardInterrupt:
 345             print("Interrupted by keyboard, closing all connections.")
 346             pass
 347         for stream in self.streams:
 348             stream.close()
 349 </pre></blockquote></p>
 350
 351 <p>The library client loops over all known "public" services,
 352 initialises it, subscribes to any updates from the service, checks and
 353 activates websocket streaming if the service provide it, and if no
 354 streaming is supported, fetches information from the service and sets
 355 up a periodic update every 60 seconds.  The output from this client
 356 can look like this:</p>

 375 <p>The exchange order book is tracked in addition to the best buy/sell
 376 price, for those that need to know the details.</p>
 377
 378 <p>The other example client is focusing on providing a curses view
 379 with updated buy/sell prices as soon as they are received from the
 380 services.  This code is located in bin/btc-rates-curses and activated
 381 by using the '-c' argument.  Without the argument the "curses" output
 382 is printed without using curses, which is useful for debugging.  The
 383 curses view look like this:</p>

 419 <p>The code for this client is too complex for a simple blog post, so
 420 you will have to check out the git repository to figure out how it
 421 work.  What I can tell is how the three last numbers on each line
 422 should be interpreted.  The first is how many seconds ago information
 423 was received from the service.  The second is how long ago, according
 424 to the service, the provided information was updated.  The last is an
 425 estimate on how often the buy/sell values change.</p>
 426
 427 <p>If you find this library useful, or would like to improve it, I
 428 would love to hear from you.  Note that for some of the services I've

 449       <div class="body"><p>Back in February, I got curious to see
 450 <a href="http://people.skolelinux.org/pere/blog/Using_VLC_to_stream_bittorrent_sources.html">if
 451 VLC now supported Bittorrent streaming</a>.  It did not, despite the
 452 fact that the idea and code to handle such streaming had been floating
 453 around for years.  I did however find
 454 <a href="https://github.com/johang/vlc-bittorrent">a standalone plugin
 455 for VLC</a> to do it, and half a year later I decided to wrap up the
 456 plugin and get it into Debian.  I uploaded it to NEW a few days ago,
 457 and am very happy to report that it
 458 <a href="https://tracker.debian.org/pkg/vlc-plugin-bittorrent">entered
 459 Debian</a> a few hours ago, and should be available in Debian/Unstable
 460 tomorrow, and Debian/Testing in a few days.</p>
 461
 462 <p>With the vlc-plugin-bittorrent package installed you should be able
 463 to stream videos using a simple call to</p>
 464
 465 <p><blockquote><pre>
 466 vlc https://archive.org/download/TheGoat/TheGoat_archive.torrent
 467 </pre></blockquote></p>
 468
 469 </p>It can handle magnet links too.  Now if only native vlc had
 470 bittorrent support.  Then a lot more would be helping each other to
 471 share public domain and creative commons movies.  The plugin need some
 472 stability work with seeking and picking the right file in a torrent
 473 with many files, but is already usable.  Please note that the plugin
 474 is not removing downloaded files when vlc is stopped, so it can fill
 475 up your disk if you are not careful.  Have fun. :)</p>
 476

 552       <div class="date">13th August 2018</div>
 553       <div class="body"><p>A few days ago, I wondered if there are any privacy respecting
 554 health monitors and/or fitness trackers available for sale these days.
 555 I would like to buy one, but do not want to share my personal data
 556 with strangers, nor be forced to have a mobile phone to get data out
 557 of the unit.  I've received some ideas, and would like to share them
 558 with you.
 559
 560 One interesting data point was a pointer to a Free Software app for
 561 Android named
 562 <a href="https://github.com/Freeyourgadget/Gadgetbridge/">Gadgetbridge</a>.
 563 It provide cloudless collection and storing of data from a variety of
 564 trackers.  Its
 565 <a href="https://github.com/Freeyourgadget/Gadgetbridge/#supported-devices">list
 566 of supported devices</a> is a good indicator for units where the
 567 protocol is fairly open, as it is obviously being handled by Free
 568 Software.  Other units are reportedly encrypting the collected
 569 information with their own public key, making sure only the vendor
 570 cloud service is able to extract data from the unit.  The people
 571 contacting me about Gadgetbirde said they were using
 572 <a href="https://us.amazfit.com/shop/bip?variant=336750">Amazfit
 573 Bip</a> and
 574 <a href="http://www.xiaomimi6phone.com/xiaomi-mi-band-3-features-release-date-rumors/">Xiaomi
 575 Band 3</a>.</p>
 576
 577 <p>I also got a suggestion to look at some of the units from Garmin.
 578 I was told their GPS watches can be connected via USB and show up as a
 579 USB storage device with
 580 <a href="https://www.gpsbabel.org/htmldoc-development/fmt_garmin_fit.html">Garmin
 581 FIT files</a> containing the collected measurements.  While
 582 proprietary, FIT files apparently can be read at least by
 583 <a href="https://www.gpsbabel.org">GPSBabel</a> and the
 584 <a href="https://apps.nextcloud.com/apps/gpxpod">GpxPod</a> Nextcloud
 585 app.  It is unclear to me if they can read step count and heart rate
 586 data.  The person I talked to was using a
 587 <a href="https://buy.garmin.com/en-US/US/p/564291">Garmin Forerunner
 588 935</a>, which is a fairly expensive unit.  I doubt it is worth it for
 589 a unit where the vendor clearly is trying its best to move from open
 590 to closed systems.  I still remember when Garmin dropped NMEA support
 591 in its GPSes.</p>
 592
 593 <p>A final idea was to build ones own unit, perhaps by basing it on a
 594 wearable hardware platforms like
 595 <a href="https://learn.adafruit.com/flora-geo-watch">the Flora Geo
 596 Watch</a>.  Sound like fun, but I had more money than time to spend on
 597 the topic, so I suspect it will have to wait for another time.</p>
 598
 599 <p>While I was working on tracking down links, I came across an
 600 inspiring TED talk by Dave Debronkart about
 601 <a href="https://archive.org/details/DavedeBronkart_2010X">being a
 602 e-patient</a>, and discovered the web site
 603 <a href="https://participatorymedicine.org/epatients/">Participatory
 604 Medicine</a>.  If you too want to track your own health and fitness
 605 without having information about your private life floating around on
 606 computers owned by others, I recommend checking it out.</p>

 625       <div class="body"><p>Dear lazyweb,</p>
 626
 627 <p>I wonder, is there a fitness tracker / health monitor available for
 628 sale today that respect the users privacy?  With this I mean a
 629 watch/bracelet capable of measuring pulse rate and other
 630 fitness/health related values (and by all means, also the correct time
 631 and location if possible), which is <strong>only</strong> provided for
 632 me to extract/read from the unit with computer without a radio beacon
 633 and Internet connection.  In other words, it do not depend on a cell
 634 phone app, and do make the measurements available via other peoples
 635 computer (aka "the cloud").  The collected data should be available
 636 using only free software.  I'm not interested in depending on some
 637 non-free software that will leave me high and dry some time in the
 638 future.  I've been unable to find any such unit.  I would like to buy
 639 it.  The ones I have seen for sale here in Norway are proud to report
 640 that they share my health data with strangers (aka "cloud enabled").
 641 Is there an alternative?  I'm not interested in giving money to people
 642 requiring me to accept "privacy terms" to allow myself to measure my
 643 own health.</p>

 661       <div class="date">31st July 2018</div>
 662       <div class="body"><p>For a while now, I have looked for a sensible way to share images
 663 with my family using a self hosted solution, as it is unacceptable to
 664 place images from my personal life under the control of strangers
 665 working for data hoarders like Google or Dropbox.  The last few days I
 666 have drafted an approach that might work out, and I would like to
 667 share it with you.  I would like to publish images on a server under
 668 my control, and point some Internet connected display units using some
 669 free and open standard to the images I published.  As my primary
 670 language is not limited to ASCII, I need to store metadata using
 671 UTF-8.  Many years ago, I hoped to find a digital photo frame capable
 672 of reading a RSS feed with image references (aka using the
 673 &lt;enclosure&gt; RSS tag), but was unable to find a current supplier
 674 of such frames.  In the end I gave up that approach.</p>
 675
 676 <p>Some months ago, I discovered that
 677 <a href="https://www.jwz.org/xscreensaver/">XScreensaver</a> is able to
 678 read images from a RSS feed, and used it to set up a screen saver on
 679 my home info screen, showing images from the Daily images feed from
 680 NASA.  This proved to work well.  More recently I discovered that
 681 <a href="https://kodi.tv">Kodi</a> (both using
 682 <a href="https://www.openelec.tv/">OpenELEC</a> and
 683 <a href="https://libreelec.tv">LibreELEC</a>) provide the
 684 <a href="https://github.com/grinsted/script.screensaver.feedreader">Feedreader</a>
 685 screen saver capable of reading a RSS feed with images and news.  For
 686 fun, I used it this summer to test Kodi on my parents TV by hooking up
 687 a Raspberry PI unit with LibreELEC, and wanted to provide them with a
 688 screen saver showing selected pictures from my selection.</p>
 689
 690 <p>Armed with motivation and a test photo frame, I set out to generate
 691 a RSS feed for the Kodi instance.  I adjusted my <a
 692 href="https://freedombox.org/">Freedombox</a> instance, created
 693 /var/www/html/privatepictures/, wrote a small Perl script to extract
 694 title and description metadata from the photo files and generate the
 695 RSS file.  I ended up using Perl instead of python, as the
 696 libimage-exiftool-perl Debian package seemed to handle the EXIF/XMP
 697 tags I ended up using, while python3-exif did not.  The relevant EXIF
 698 tags only support ASCII, so I had to find better alternatives.  XMP
 699 seem to have the support I need.</p>
 700
 701 <p>I am a bit unsure which EXIF/XMP tags to use, as I would like to
 702 use tags that can be easily added/updated using normal free software
 703 photo managing software.  I ended up using the tags set using this
 704 exiftool command, as these tags can also be set using digiKam:</p>
 705
 706 <blockquote><pre>
 707 exiftool -headline='The RSS image title' \
 708   -description='The RSS image description.' \
 709   -subject+=for-family photo.jpeg
 710 </pre></blockquote>

 712 <p>I initially tried the "-title" and "keyword" tags, but they were
 713 invisible in digiKam, so I changed to "-headline" and "-subject".  I
 714 use the keyword/subject 'for-family' to flag that the photo should be
 715 shared with my family.  Images with this keyword set are located and
 716 copied into my Freedombox for the RSS generating script to find.</p>
 717
 718 <p>Are there better ways to do this?  Get in touch if you have better
 719 suggestions.</p>
