- <description><p>I am working on publishing yet another book related to Creative
-Commons. This time it is a book filled with interviews and histories
-from those around the globe making a living using Creative
-Commons.</p>
-
-<p>Yesterday, after many months of hard work by several volunteer
-translators, the first draft of a Norwegian Bokmål edition of the book
-<a href="https://madewith.cc">Made with Creative Commons from 2017</a>
-was complete. The Spanish translation is also complete, while the
-Dutch, Polish, German and Ukraine edition need a lot of work. Get in
-touch if you want to help make those happen, or would like to
-translate into your mother tongue.</p>
-
-<p>The whole book project started when
-<a href="http://gwolf.org/node/4102">Gunnar Wolf announced</a> that he
-was going to make a Spanish edition of the book. I noticed, and
-offered some input on how to make a book, based on my experience with
-translating the
-<a href="https://www.lulu.com/shop/lawrence-lessig/fri-kultur/paperback/product-22441576.html">Free
-Culture</a> and
-<a href="https://debian-handbook.info/get/#norwegian">The Debian
-Administrator's Handbook</a> books to Norwegian Bokmål. To make a
-long story short, we ended up working on a Bokmål edition, and now the
-first rough translation is complete, thanks to the hard work of
-Ole-Erik Yrvin, Ingrid Yrvin, Allan Nordhøy and myself. The first
-proof reading is almost done, and only the second and third proof
-reading remains. We will also need to translate the 14 figures and
-create a book cover. Once it is done we will publish the book on
-paper, as well as in PDF, ePub and possibly Mobi formats.</p>
-
-<p>The book itself originates as a manuscript on Google Docs, is
-downloaded as ODT from there and converted to Markdown using pandoc.
-The Markdown in modified by a script before is converted to DocBook
-using pandoc. The DocBook is modified again using a script before it
-is used to create a Gettext POT file for translators. The translated
-PO file is then combined with the earlier mentioned DocBook file to
-create a translated DocBook file, which finally is given to dblatex to
-create the final PDF. The end result is a set of editions of the
-manuscript, one English and one for each of the translations.</p>
-
-<p>The translation is conducted using
-<a href="https://hosted.weblate.org/projects/madewithcc/translation/">the
-Weblate web based translation system</a>. Please have a look there
-and get in touch if you would like to help out with proof
-reading. :)</p>

+ <description><p>As part of my involvement in
+<a href="https://gitlab.com/OsloMet-ABI/nikita-noark5-core">the Nikita
+archive API project</a>, I've been importing a fairly large lump of
+emails into a test instance of the archive to see how well this would
+go. I picked a subset of <a href="https://notmuchmail.org/">my
+notmuch email database</a>, all public emails sent to me via
+@lists.debian.org, giving me a set of around 216 000 emails to import.
+In the process, I had a look at the various attachments included in
+these emails, to figure out what to do with attachments, and noticed
+that one of the most common attachment formats do not have
+<a href="https://www.iana.org/assignments/media-types/media-types.xhtml">an
+official MIME type</a> registered with IANA/IETF. The output from
+diff, ie the input for patch, is on the top 10 list of formats
+included in these emails. At the moment people seem to use either
+text/x-patch or text/x-diff, but neither is officially registered. It
+would be better if one official MIME type were registered and used
+everywhere.</p>
+
+<p>To try to get one official MIME type for these files, I've brought
+up the topic on
+<a href="https://www.ietf.org/mailman/listinfo/media-types">the
+media-types mailing list</a>. If you are interested in discussion
+which MIME type to use as the official for patch files, or involved in
+making software using a MIME type for patches, perhaps you would like
+to join the discussion?</p>

- <title>Debian used in the subway info screens in Oslo, Norway</title>

- <description><p>Today I was pleasantly surprised to discover my operating system of
-choice, Debian, was used in the info screens on the subway stations.
-While passing Nydalen subway station in Oslo, Norway, I discovered the
-info screen booting with some text scrolling. I was not quick enough
-with my camera to be able to record a video of the scrolling boot
-screen, but I did get a photo from when the boot got stuck with a
-corrupt file system:
-
-<p align="center"><a href="http://people.skolelinux.org/pere/blog/images/2018-03-02-ruter-debian-lenny.jpeg"><img align="center" width="40%" src="http://people.skolelinux.org/pere/blog/images/2018-03-02-ruter-debian-lenny.jpeg" alt="[photo of subway info screen]"></a></p>
-
-<p>While I am happy to see Debian used more places, some details of the
-content on the screen worries me.</p>
-
-<p>The image show the version booting is 'Debian GNU/Linux lenny/sid',
-indicating that this is based on code taken from Debian Unstable/Sid
-after Debian Etch (version 4) was released 2007-04-08 and before
-Debian Lenny (version 5) was released 2009-02-14. Since Lenny Debian
-has released version 6 (Squeeze) 2011-02-06, 7 (Wheezy) 2013-05-04, 8
-(Jessie) 2015-04-25 and 9 (Stretch) 2017-06-15, according to
-<a href="https://en.wikipedia.org/wiki/Debian_version_history">a Debian
-version history on Wikpedia</a>. This mean the system is running
-around 10 year old code, with no security fixes from the vendor for
-many years.</p>
-
-<p>This is not the first time I discover the Oslo subway company,
-Ruter, running outdated software. In 2012,
-<a href="http://people.skolelinux.org/pere/blog/Er_billettautomatene_til_kollektivtrafikken_i_Oslo_uten_sikkerhetsoppdateringer_.html">I
-discovered the ticket vending machines were running Windows 2000</a>,
-and this was
-<a href="http://people.skolelinux.org/pere/blog/Fortsatt_ingen_sikkerhetsoppdateringer_for_billettautomatene_til_kollektivtrafikken_i_Oslo_.html">still
-the case in 2016</a>. Given the response from the responsible people
-in 2016, I would assume the machines are still running unpatched
-Windows 2000. Thus, an unpatched Debian setup come as no surprise.</p>

+
+<p>My current home stereo is a patchwork of various pieces I got on
+flee markeds over the years. It is amazing what kind of equipment
+show up there. I've been wondering for a while if it was possible to
+measure how well this equipment is working together, and decided to
+see how far I could get using free software. After trawling the web I
+came across an article from DIY Audio and Video on
+<a href="https://www.diyaudioandvideo.com/Tutorial/SpeakerResponseTesting/">Speaker
+Testing and Analysis</a> describing how to test speakers, and it listing
+several software options, among them
+<a href="https://sourceforge.net/projects/audmes/">AUDio MEasurement
+System (AUDMES)</a>. It is the only free software system I could find
+focusing on measuring speakers and audio frequency response. In the
+process I also found an interesting article from NOVO on
+<a href="http://novo.press/understanding-speaker-specifications-and-frequency-response/">Understanding
+Speaker Specifications and Frequency Response</a> and an article from
+ecoustics on
+<a href="https://www.ecoustics.com/articles/understanding-speaker-frequency-response/">Understanding
+Speaker Frequency Response</a>, with a lot of information on what to
+look for and how to interpret the graphs. Armed with this knowledge,
+I set out to measure the state of my speakers.</p>
+
+<p>The first hurdle was that AUDMES hadn't seen a commit for 10 years
+and did not build with current compilers and libraries. I got in
+touch with its author, who no longer was spending time on the program
+but gave me write access to the subversion repository on Sourceforge.
+The end result is that now the code build on Linux and is capable of
+saving and loading the collected frequency response data in CSV
+format. The application is quite nice and flexible, and I was able to
+select the input and output audio interfaces independently. This made
+it possible to use a USB mixer as the input source, while sending
+output via my laptop headphone connection. I lacked the hardware and
+cabling to figure out a different way to get independent cabling to
+speakers and microphone.</p>
+
+<p>Using this setup I could see how a large range of high frequencies
+apparently were not making it out of my speakers. The picture show
+the frequency response measurement of one of the speakers. Note the
+frequency lines seem to be slightly misaligned, compared to the CSV
+output from the program. I can not hear several of these are high
+frequencies, according to measurement from
+<a href="http://freehearingtestsoftware.com">Free Hearing Test
+Software</a>, an freeware system to measure your hearing (still
+looking for a free software alternative), so I do not know if they are
+coming out out the speakers. I thus do not quite know how to figure
+out if the missing frequencies is a problem with the microphone, the
+amplifier or the speakers, but I managed to rule out the audio card in my
+PC by measuring my Bose noise canceling headset using its own
+microphone. This setup was able to see the high frequency tones, so
+the problem with my stereo had to be in the amplifier or speakers.</p>
+
+<p>Anyway, to try to role out one factor I ended up picking up a new
+set of speakers at a flee marked, and these work a lot better than the
+old speakers, so I guess the microphone and amplifier is OK. If you
+need to measure your own speakers, check out AUDMES. If more people
+get involved, perhaps the project could become good enough to
+<a href="https://bugs.debian.org/910876">include in Debian</a>? And if
+you know of some other free software to measure speakers and amplifier
+performance, please let me know. I am aware of the freeware option
+<a href="https://www.roomeqwizard.com/">REW</a>, but I want something
+that can be developed also when the vendor looses interest.</p>

+ <description><p>Bittorrent is as far as I know, currently the most efficient way to
+distribute content on the Internet. It is used all by all sorts of
+content providers, from national TV stations like
+<a href="https://www.nrk.no/">NRK</a>, Linux distributors like
+<a href="https://www.debian.org/">Debian</a> and
+<a href="https://www.ubuntu.com/">Ubuntu</a>, and of course the
+<a href="https://archive.org/">Internet archive</A>.
+
+<p>Almost a month ago
+<a href="https://tracker.debian.org/pkg/vlc-plugin-bittorrent">a new
+package adding Bittorrent support to VLC</a> became available in
+Debian testing and unstable. To test it, simply install it like
+this:</p>
-<ul>
-
-<li><a href="http://git.savannah.nongnu.org/cgit/sysvinit.git">sysvinit</a></li>
-<li><a href="http://git.savannah.nongnu.org/cgit/sysvinit/insserv.git">insserv</a></li>
-<li><a href="http://git.savannah.nongnu.org/cgit/sysvinit/startpar.git">startpar</a></li>
-
-</ul>
+<p><pre>
+apt install vlc-plugin-bittorrent
+</pre></p>
-<p>I do not really spend much time on the project these days, and I
-has mostly retired, but found it best to migrate the source to a good
-version control system to help those willing to move it forward.</p>
+<p>Since the plugin was made available for the first time in Debian,
+several improvements have been made to it. In version 2.2-4, now
+available in both testing and unstable, a desktop file is provided to
+teach browsers to start VLC when the user click on torrent files or
+magnet links. The last part is thanks to me finally understanding
+what the strange x-scheme-handler style MIME types in desktop files
+are used for. By adding x-scheme-handler/magnet to the MimeType entry
+in the desktop file, at least the browsers Firefox and Chromium will
+suggest to start VLC when selecting a magnet URI on a web page. The
+end result is that now, with the plugin installed in Buster and Sid,
+one can visit any
+<a href="https://archive.org/details/CopyingIsNotTheft1080p">Internet
+Archive page with movies</a> using a web browser and click on the
+torrent link to start streaming the movie.</p>
+
+<p>Note, there is still some misfeatures in the plugin. One is the
+fact that it will hang and
+<a href="https://github.com/johang/vlc-bittorrent/issues/13">block VLC
+from exiting until the torrent streaming starts</a>. Another is the
+fact that it
+<a href="https://github.com/johang/vlc-bittorrent/issues/9">will pick
+and play a random file in a multi file torrent</a>. This is not
+always the video file you want. Combined with the first it can be a
+bit hard to get the video streaming going. But when it work, it seem
+to do a good job.</p>
+
+<p>For the Debian packaging, I would love to find a good way to test
+if the plugin work with VLC using autopkgtest. I tried, but do not
+know enough of the inner workings of VLC to get it working. For now
+the autopkgtest script is only checking if the .so file was
+successfully loaded by VLC. If you have any suggestions, please
+submit a patch to the Debian bug tracking system.</p>

- <title>Using VLC to stream bittorrent sources</title>

- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Using_VLC_to_stream_bittorrent_sources.html</guid>
- <pubDate>Wed, 14 Feb 2018 08:00:00 +0100</pubDate>
- <description><p>A few days ago, a new major version of
-<a href="https://www.videolan.org/">VLC</a> was announced, and I
-decided to check out if it now supported streaming over
-<a href="http://bittorrent.org/">bittorrent</a> and
-<a href="https://webtorrent.io">webtorrent</a>. Bittorrent is one of
-the most efficient ways to distribute large files on the Internet, and
-Webtorrent is a variant of Bittorrent using
-<a href="https://webrtc.org">WebRTC</a> as its transport channel,
-allowing web pages to stream and share files using the same technique.
-The network protocols are similar but not identical, so a client
-supporting one of them can not talk to a client supporting the other.
-I was a bit surprised with what I discovered when I started to look.
-Looking at
-<a href="https://www.videolan.org/vlc/releases/3.0.0.html">the release
-notes</a> did not help answering this question, so I started searching
-the web. I found several news articles from 2013, most of them
-tracing the news from Torrentfreak
-("<a href=https://torrentfreak.com/open-source-giant-vlc-mulls-bittorrent-support-130211/">Open
-Source Giant VLC Mulls BitTorrent Streaming Support</a>"), about a
-initiative to pay someone to create a VLC patch for bittorrent
-support. To figure out what happend with this initiative, I headed
-over to the #videolan IRC channel and asked if there were some bug or
-feature request tickets tracking such feature. I got an answer from
-lead developer Jean-Babtiste Kempf, telling me that there was a patch
-but neither he nor anyone else knew where it was. So I searched a bit
-more, and came across an independent
-<a href="https://github.com/johang/vlc-bittorrent">VLC plugin to add
-bittorrent support</a>, created by Johan Gunnarsson in 2016/2017.
-Again according to Jean-Babtiste, this is not the patch he was talking
-about.</p>
-
-<p>Anyway, to test the plugin, I made a working Debian package from
-the git repository, with some modifications. After installing this
-package, I could stream videos from
-<a href="https://www.archive.org/">The Internet Archive</a> using VLC
-commands like this:</p>

-<p>The plugin is supposed to handle magnet links too, but since The
-Internet Archive do not have magnet links and I did not want to spend
-time tracking down another source, I have not tested it. It can take
-quite a while before the video start playing without any indication of
-what is going on from VLC. It took 10-20 seconds when I measured it.
-Some times the plugin seem unable to find the correct video file to
-play, and show the metadata XML file name in the VLC status line. I
-have no idea why.</p>
-
-<p>I have created a <a href="https://bugs.debian.org/890360">request for
-a new package in Debian (RFP)</a> and
-<a href="https://github.com/johang/vlc-bittorrent/issues/1">asked if

-wait to see what come out of this. I do not want to maintain a
-package that is not maintained upstream, nor do I really have time to
-maintain more packages myself, so I might leave it at this. But I
-really hope someone step up to do the packaging, and hope upstream is
-still maintaining the source. If you want to help, please update the
-RFP request or the upstream issue.</p>

+ <description><p>I have earlier covered the basics of trusted timestamping using the
+'openssl ts' client. See blog post for
+<a href="http://people.skolelinux.org/pere/blog/Public_Trusted_Timestamping_services_for_everyone.html">2014</a>,
+<a href="http://people.skolelinux.org/pere/blog/syslog_trusted_timestamp___chain_of_trusted_timestamps_for_your_syslog.html">2016</a>
+and
+<a href="http://people.skolelinux.org/pere/blog/Idea_for_storing_trusted_timestamps_in_a_Noark_5_archive.html">2017</a>
+for those stories. But some times I want to integrate the timestamping
+in other code, and recently I needed to integrate it into Python.
+After searching a bit, I found
+<a href="https://dev.entrouvert.org/projects/python-rfc3161">the
+rfc3161 library</a> which seemed like a good fit, but I soon
+discovered it only worked for python version 2, and I needed something
+that work with python version 3. Luckily I next came across
+<a href="https://github.com/trbs/rfc3161ng/">the rfc3161ng library</a>,
+a fork of the original rfc3161 library. Not only is it working with
+python 3, it have fixed a few of the bugs in the original library, and
+it has an active maintainer. I decided to wrap it up and make it
+<a href="https://tracker.debian.org/pkg/python-rfc3161ng">available in
+Debian</a>, and a few days ago it entered Debian unstable and testing.</p>
+
+<p>Using the library is fairly straight forward. The only slightly
+problematic step is to fetch the required certificates to verify the
+timestamp. For some services it is straight forward, while for others
+I have not yet figured out how to do it. Here is a small standalone
+code example based on of the integration tests in the library code:</p>
+
+<pre>
+#!/usr/bin/python3
+
+"""
+
+Python 3 script demonstrating how to use the rfc3161ng module to
+get trusted timestamps.
+
+The license of this code is the same as the license of the rfc3161ng
+library, ie MIT/BSD.
+
+"""
+
+import os
+import pyasn1.codec.der
+import rfc3161ng
+import subprocess
+import tempfile
+import urllib.request
+
+def store(f, data):
+ f.write(data)
+ f.flush()
+ f.seek(0)
+
+def fetch(url, f=None):
+ response = urllib.request.urlopen(url)
+ data = response.read()
+ if f:
+ store(f, data)
+ return data
+
+def main():
+ with tempfile.NamedTemporaryFile() as cert_f,\
+ tempfile.NamedTemporaryFile() as ca_f,\
+ tempfile.NamedTemporaryFile() as msg_f,\
+ tempfile.NamedTemporaryFile() as tsr_f:
+
+ # First fetch certificates used by service
+ certificate_data = fetch('https://freetsa.org/files/tsa.crt', cert_f)
+ ca_data_data = fetch('https://freetsa.org/files/cacert.pem', ca_f)
+
+ # Then timestamp the message
+ timestamper = \
+ rfc3161ng.RemoteTimestamper('http://freetsa.org/tsr',
+ certificate=certificate_data)
+ data = b"Python forever!\n"
+ tsr = timestamper(data=data, return_tsr=True)
+
+ # Finally, convert message and response to something 'openssl ts' can verify
+ store(msg_f, data)
+ store(tsr_f, pyasn1.codec.der.encoder.encode(tsr))
+ args = ["openssl", "ts", "-verify",
+ "-data", msg_f.name,
+ "-in", tsr_f.name,
+ "-CAfile", ca_f.name,
+ "-untrusted", cert_f.name]
+ subprocess.check_call(args)
+
+if '__main__' == __name__:
+ main()
+</pre>
+
+<p>The code fetches the required certificates, store them as temporary
+files, timestamp a simple message, store the message and timestamp to
+disk and ask 'openssl ts' to verify the timestamp. A timestamp is
+around 1.5 kiB in size, and should be fairly easy to store for future
+use.</p>

-
-<p>«I den sørvestlige byen Kashgar nærmere grensa til
-Sentral-Asia meldes det nå at 120.000 uigurer er internert i såkalte
-omskoleringsleirer. Samtidig er det innført et omfattende
-helsesjekk-program med innsamling og lagring av DNA-prøver fra
-absolutt alle innbyggerne. De mest avanserte overvåkingsmetodene
-testes ut her. Programmer for å gjenkjenne ansikter og stemmer er på
-plass i regionen. Der har de lokale myndighetene begynt å installere
-GPS-systemer i alle kjøretøy og egne sporingsapper i
-mobiltelefoner.</p>
-
-<p>Politimetodene griper så dypt inn i folks dagligliv at motstanden

+ <description><p>A few days, I rescued a Windows victim over to Debian. To try to
+rescue the remains, I helped set up automatic sync with Google Drive.
+I did not find any sensible Debian package handling this
+automatically, so I rebuild the grive2 source from
+<a href="http://www.webupd8.org/">the Ubuntu UPD8 PPA</a> to do the
+task and added a autostart desktop entry and a small shell script to
+run in the background while the user is logged in to do the sync.
+Here is a sketch of the setup for future reference.</p>
+
+<p>I first created <tt>~/googledrive</tt>, entered the directory and
+ran '<tt>grive -a</tt>' to authenticate the machine/user. Next, I
+created a autostart hook in <tt>~/.config/autostart/grive.desktop</tt>
+to start the sync when the user log in:</p>
+
+<p><blockquote><pre>
+[Desktop Entry]
+Name=Google drive autosync
+Type=Application
+Exec=/home/user/bin/grive-sync
+</pre></blockquote></p>
+
+<p>Finally, I wrote the <tt>~/bin/grive-sync</tt> script to sync
+~/googledrive/ with the files in Google Drive.</p>
+
+<p><blockquote><pre>
+#!/bin/sh
+set -e
+cd ~/
+cleanup() {
+ if [ "$syncpid" ] ; then
+ kill $syncpid
+ fi
+}
+trap cleanup EXIT INT QUIT
+/usr/lib/grive/grive-sync.sh listen googledrive 2>&1 | sed "s%^%$0:%" &
+syncpdi=$!
+while true; do
+ if ! xhost >/dev/null 2>&1 ; then
+ echo "no DISPLAY, exiting as the user probably logged out"
+ exit 1
+ fi
+ if [ ! -e /run/user/1000/grive-sync.sh_googledrive ] ; then
+ /usr/lib/grive/grive-sync.sh sync googledrive
+ fi
+ sleep 300
+done 2>&1 | sed "s%^%$0:%"
+</pre></blockquote></p>
+
+<p>Feel free to use the setup if you want. It can be assumed to be
+GNU GPL v2 licensed (or any later version, at your leisure), but I
+doubt this code is possible to claim copyright on.</p>

+ <description><p>It would come as no surprise to anyone that I am interested in
+bitcoins and virtual currencies. I've been keeping an eye on virtual
+currencies for many years, and it is part of the reason a few months
+ago, I started writing a python library for collecting currency
+exchange rates and trade on virtual currency exchanges. I decided to
+name the end result valutakrambod, which perhaps can be translated to
+small currency shop.</p>
+
+<p>The library uses the tornado python library to handle HTTP and
+websocket connections, and provide a asynchronous system for
+connecting to and tracking several services. The code is available
+from
+<a href="http://github.com/petterreinholdtsen/valutakrambod">github</a>.</p>
+
+</p>There are two example clients of the library. One is very simple and
+list every updated buy/sell price received from the various services.
+This code is started by running bin/btc-rates and call the client code
+in valutakrambod/client.py. The simple client look like this:</p>
+
+<p><blockquote><pre>
+import functools
+import tornado.ioloop
+import valutakrambod
+class SimpleClient(object):
+ def __init__(self):
+ self.services = []
+ self.streams = []
+ pass
+ def newdata(self, service, pair, changed):
+ print("%-15s %s-%s: %8.3f %8.3f" % (
+ service.servicename(),
+ pair[0],
+ pair[1],
+ service.rates[pair]['ask'],
+ service.rates[pair]['bid'])
+ )
+ async def refresh(self, service):
+ await service.fetchRates(service.wantedpairs)
+ def run(self):
+ self.ioloop = tornado.ioloop.IOLoop.current()
+ self.services = valutakrambod.service.knownServices()
+ for e in self.services:
+ service = e()
+ service.subscribe(self.newdata)
+ stream = service.websocket()
+ if stream:
+ self.streams.append(stream)
+ else:
+ # Fetch information from non-streaming services immediately
+ self.ioloop.call_later(len(self.services),
+ functools.partial(self.refresh, service))
+ # as well as regularly
+ service.periodicUpdate(60)
+ for stream in self.streams:
+ stream.connect()
+ try:
+ self.ioloop.start()
+ except KeyboardInterrupt:
+ print("Interrupted by keyboard, closing all connections.")
+ pass
+ for stream in self.streams:
+ stream.close()
+</pre></blockquote></p>
-<p>We write 2018, and it is 30 years since Unicode was introduced.
-Most of us in Norway have come to expect the use of our alphabet to
-just work with any computer system. But it is apparently beyond reach
-of the computers printing recites at a restaurant. Recently I visited
-a Peppes pizza resturant, and noticed a few details on the recite.
-Notice how 'ø' and 'å' are replaced with strange symbols in
-'Servitør', 'Å BETALE', 'Beløp pr. gjest', 'Takk for besøket.' and 'Vi
-gleder oss til å se deg igjen'.</p>
+<p>The library client loops over all known "public" services,
+initialises it, subscribes to any updates from the service, checks and
+activates websocket streaming if the service provide it, and if no
+streaming is supported, fetches information from the service and sets
+up a periodic update every 60 seconds. The output from this client
+can look like this:</p>
-<p>I would say that this state is passed sad and over in embarrassing.</p>

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

-<p>I removed personal and private information to be nice.</p>
+<p>The code for this client is too complex for a simple blog post, so
+you will have to check out the git repository to figure out how it
+work. What I can tell is how the three last numbers on each line
+should be interpreted. The first is how many seconds ago information
+was received from the service. The second is how long ago, according
+to the service, the provided information was updated. The last is an
+estimate on how often the buy/sell values change.</p>
+
+<p>If you find this library useful, or would like to improve it, I
+would love to hear from you. Note that for some of the services I've
+implemented a trading API. It might be the topic of a future blog
+post.</p>

-<p> I keep finding more data sources. I found the cinemovies source
-just a few days ago, and as you can see from the summary, it extended
-my list with 63 movies. Check out the mklist-* scripts in the git
-repository if you are curious how the lists are created. Many of the
-titles are extracted using searches on IMDB, where I look for the
-title and year, and accept search results with only one movie listed
-if the year matches. This allow me to automatically use many lists of
-movies without IMDB title ID references at the cost of increasing the
-risk of wrongly identify a IMDB title ID as public domain. So far my
-random manual checks have indicated that the method is solid, but I
-really wish all lists of public domain movies would include unique
-movie identifier like the IMDB title ID. It would make the job of
-counting movies in the public domain a lot easier.</p>
+</p>It can handle magnet links too. Now if only native vlc had
+bittorrent support. Then a lot more would be helping each other to
+share public domain and creative commons movies. The plugin need some
+stability work with seeking and picking the right file in a torrent
+with many files, but is already usable. Please note that the plugin
+is not removing downloaded files when vlc is stopped, so it can fill
+up your disk if you are not careful. Have fun. :)</p>

+<p>I would love to get help maintaining this package. Get in touch if
+you are interested.</p>

- <description><p>I går var jeg i Follo tingrett som sakkyndig vitne og presenterte
- mine undersøkelser rundt
- <a href="https://github.com/petterreinholdtsen/public-domain-free-imdb">telling
- av filmverk i det fri</a>, relatert til
- <a href="https://www.nuug.no/">foreningen NUUG</a>s involvering i
- <a href="https://www.nuug.no/news/tags/dns-domenebeslag/">saken om
- Økokrims beslag og senere inndragning av DNS-domenet
- popcorn-time.no</a>. Jeg snakket om flere ting, men mest om min
- vurdering av hvordan filmbransjen har målt hvor ulovlig Popcorn Time
- er. Filmbransjens måling er så vidt jeg kan se videreformidlet uten
- endringer av norsk politi, og domstolene har lagt målingen til grunn
- når de har vurdert Popcorn Time både i Norge og i utlandet (tallet
- 99% er referert også i utenlandske domsavgjørelser).</p>
-
-<p>I forkant av mitt vitnemål skrev jeg et notat, mest til meg selv,
- med de punktene jeg ønsket å få frem. Her er en kopi av notatet jeg
- skrev og ga til aktoratet. Merkelig nok ville ikke dommerene ha
- notatet, så hvis jeg forsto rettsprosessen riktig ble kun
- histogram-grafen lagt inn i dokumentasjonen i saken. Dommerne var
- visst bare interessert i å forholde seg til det jeg sa i retten,
- ikke det jeg hadde skrevet i forkant. Uansett så antar jeg at flere
- enn meg kan ha glede av teksten, og publiserer den derfor her.
- Legger ved avskrift av dokument 09,13, som er det sentrale
- dokumentet jeg kommenterer.</p>
-
-<p><strong>Kommentarer til «Evaluation of (il)legality» for Popcorn
- Time</strong></p>
-
-<p><strong>Oppsummering</strong></p>
-
-<p>Målemetoden som Økokrim har lagt til grunn når de påstår at 99% av
- filmene tilgjengelig fra Popcorn Time deles ulovlig har
- svakheter.</p>
-
-<p>De eller den som har vurdert hvorvidt filmer kan lovlig deles har
- ikke lyktes med å identifisere filmer som kan deles lovlig og har
- tilsynelatende antatt at kun veldig gamle filmer kan deles lovlig.
- Økokrim legger til grunn at det bare finnes èn film, Charlie
- Chaplin-filmen «The Circus» fra 1928, som kan deles fritt blant de
- som ble observert tilgjengelig via ulike Popcorn Time-varianter.
- Jeg finner tre flere blant de observerte filmene: «The Brain That
- Wouldn't Die» fra 1962, «God’s Little Acre» fra 1958 og «She Wore a
- Yellow Ribbon» fra 1949. Det er godt mulig det finnes flere. Det
- finnes dermed minst fire ganger så mange filmer som lovlig kan deles
- på Internett i datasettet Økokrim har lagt til grunn når det påstås
- at mindre enn 1 % kan deles lovlig.</p>
-
-<p>Dernest, utplukket som gjøres ved søk på tilfeldige ord hentet fra
- ordlisten til Dale-Chall avviker fra årsfordelingen til de brukte
- filmkatalogene som helhet, hvilket påvirker fordelingen mellom
- filmer som kan lovlig deles og filmer som ikke kan lovlig deles. I
- tillegg gir valg av øvre del (de fem første) av søkeresultatene et
- avvik fra riktig årsfordeling, hvilket påvirker fordelingen av verk
- i det fri i søkeresultatet.</p>
-
-<p>Det som måles er ikke (u)lovligheten knyttet til bruken av Popcorn
- Time, men (u)lovligheten til innholdet i bittorrent-filmkataloger
- som vedlikeholdes uavhengig av Popcorn Time.</p>
-
-<p>Omtalte dokumenter: 09,12, <a href="#dok-09-13">09,13</a>, 09,14,
-09,18, 09,19, 09,20.</p>
-
-<p><strong>Utfyllende kommentarer</strong></p>
-
-<p>Økokrim har forklart domstolene at minst 99% av alt som er
- tilgjengelig fra ulike Popcorn Time-varianter deles ulovlig på
- Internet. Jeg ble nysgjerrig på hvordan de er kommet frem til dette
- tallet, og dette notatet er en samling kommentarer rundt målingen
- Økokrim henviser til. Litt av bakgrunnen for at jeg valgte å se på
- saken er at jeg er interessert i å identifisere og telle hvor mange
- kunstneriske verk som er falt i det fri eller av andre grunner kan
- lovlig deles på Internett, og dermed var interessert i hvordan en
- hadde funnet den ene prosenten som kanskje deles lovlig.</p>
-
-<p>Andelen på 99% kommer fra et ukreditert og udatert notatet som tar
- mål av seg å dokumentere en metode for å måle hvor (u)lovlig ulike
- Popcorn Time-varianter er.</p>
-
-<p>Raskt oppsummert, så forteller metodedokumentet at på grunn av at
- det ikke er mulig å få tak i komplett liste over alle filmtitler
- tilgjengelig via Popcorn Time, så lages noe som skal være et
- representativt utvalg ved å velge 50 søkeord større enn tre tegn fra
- ordlisten kjent som Dale-Chall. For hvert søkeord gjøres et søk og
- de første fem filmene i søkeresultatet samles inn inntil 100 unike
- filmtitler er funnet. Hvis 50 søkeord ikke var tilstrekkelig for å
- nå 100 unike filmtitler ble flere filmer fra hvert søkeresultat lagt
- til. Hvis dette heller ikke var tilstrekkelig, så ble det hentet ut
- og søkt på flere tilfeldig valgte søkeord inntil 100 unike
- filmtitler var identifisert.</p>
-
-<p>Deretter ble for hver av filmtitlene «vurdert hvorvidt det var
- rimelig å forvente om at verket var vernet av copyright, ved å se på
- om filmen var tilgjengelig i IMDB, samt se på regissør,
- utgivelsesår, når det var utgitt for bestemte markedsområder samt
- hvilke produksjons- og distribusjonsselskap som var registrert» (min
- oversettelse).</p>
-
-<p>Metoden er gjengitt både i de ukrediterte dokumentene 09,13 og
- 09,19, samt beskrevet fra side 47 i dokument 09,20, lysark datert
- 2017-02-01. Sistnevnte er kreditert Geerart Bourlon fra Motion
- Picture Association EMEA. Metoden virker å ha flere svakheter som
- gir resultatene en slagside. Den starter med å slå fast at det ikke
- er mulig å hente ut en komplett liste over alle filmtitler som er
- tilgjengelig, og at dette er bakgrunnen for metodevalget. Denne
- forutsetningen er ikke i tråd med det som står i dokument 09,12, som
- ikke heller har oppgitt forfatter og dato. Dokument 09,12 forteller
- hvordan hele kataloginnholdet ble lasted ned og talt opp. Dokument
- 09,12 er muligens samme rapport som ble referert til i dom fra Oslo
- Tingrett 2017-11-03
- (<a href="https://www.domstol.no/no/Enkelt-domstol/Oslo--tingrett/Nyheter/ma-sperre-for-popcorn-time/">sak
- 17-093347TVI-OTIR/05</a>) som rapport av 1. juni 2017 av Alexander
- Kind Petersen, men jeg har ikke sammenlignet dokumentene ord for ord
- for å kontrollere dette.</p>
-
-<p>IMDB er en forkortelse for The Internet Movie Database, en
- anerkjent kommersiell nettjeneste som brukes aktivt av både
- filmbransjen og andre til å holde rede på hvilke spillefilmer (og
- endel andre filmer) som finnes eller er under produksjon, og
- informasjon om disse filmene. Datakvaliteten er høy, med få feil og
- få filmer som mangler. IMDB viser ikke informasjon om
- opphavsrettslig status for filmene på infosiden for hver film. Som
- del av IMDB-tjenesten finnes det lister med filmer laget av
- frivillige som lister opp det som antas å være verk i det fri.</p>
-
-<p>Det finnes flere kilder som kan brukes til å finne filmer som er
- allemannseie (public domain) eller har bruksvilkår som gjør det
- lovlig for alleå dele dem på Internett. Jeg har de siste ukene
- forsøkt å samle og krysskoble disse listene for å forsøke å telle
- antall filmer i det fri. Ved å ta utgangspunkt i slike lister (og
- publiserte filmer for Internett-arkivets del), har jeg så langt
- klart å identifisere over 11 000 filmer, hovedsaklig spillefilmer.
-
-<p>De aller fleste oppføringene er hentet fra IMDB selv, basert på det
- faktum at alle filmer laget i USA før 1923 er falt i det fri.
- Tilsvarende tidsgrense for Storbritannia er 1912-07-01, men dette
- utgjør bare veldig liten del av spillefilmene i IMDB (19 totalt).
- En annen stor andel kommer fra Internett-arkivet, der jeg har
- identifisert filmer med referanse til IMDB. Internett-arkivet, som
- holder til i USA, har som
- <a href="https://archive.org/about/terms.php">policy å kun publisere
- filmer som det er lovlig å distribuere</a>. Jeg har under arbeidet
- kommet over flere filmer som har blitt fjernet fra
- Internett-arkivet, hvilket gjør at jeg konkluderer med at folkene
- som kontrollerer Internett-arkivet har et aktivt forhold til å kun
- ha lovlig innhold der, selv om det i stor grad er drevet av
- frivillige. En annen stor liste med filmer kommer fra det
- kommersielle selskapet Retro Film Vault, som selger allemannseide
- filmer til TV- og filmbransjen, Jeg har også benyttet meg av lister
- over filmer som hevdes å være allemannseie, det være seg Public
- Domain Review, Public Domain Torrents og Public Domain Movies (.net
- og .info), samt lister over filmer med Creative Commons-lisensiering
- fra Wikipedia, VODO og The Hill Productions. Jeg har gjort endel
- stikkontroll ved å vurdere filmer som kun omtales på en liste. Der
- jeg har funnet feil som har gjort meg i tvil om vurderingen til de
- som har laget listen har jeg forkastet listen fullstendig (gjelder
- en liste fra IMDB).</p>
-
-<p>Ved å ta utgangspunkt i verk som kan antas å være lovlig delt på
- Internett (fra blant annet Internett-arkivet, Public Domain
- Torrents, Public Domain Reivew og Public Domain Movies), og knytte
- dem til oppføringer i IMDB, så har jeg så langt klart å identifisere
- over 11 000 filmer (hovedsaklig spillefilmer) det er grunn til å tro
- kan lovlig distribueres av alle på Internett. Som ekstra kilder er
- det brukt lister over filmer som antas/påstås å være allemannseie.
- Disse kildene kommer fra miljøer som jobber for å gjøre tilgjengelig
- for almennheten alle verk som er falt i det fri eller har
- bruksvilkår som tillater deling.
-
-<p>I tillegg til de over 11 000 filmene der tittel-ID i IMDB er
- identifisert, har jeg funnet mer enn 20 000 oppføringer der jeg ennå
- ikke har hatt kapasitet til å spore opp tittel-ID i IMDB. Noen av
- disse er nok duplikater av de IMDB-oppføringene som er identifisert
- så langt, men neppe alle. Retro Film Vault hevder å ha 44 000
- filmverk i det fri i sin katalog, så det er mulig at det reelle
- tallet er betydelig høyere enn de jeg har klart å identifisere så
- langt. Konklusjonen er at tallet 11 000 er nedre grense for hvor
- mange filmer i IMDB som kan lovlig deles på Internett. I følge <a
- href="http://www.imdb.com/stats">statistikk fra IMDB</a> er det 4.6
- millioner titler registrert, hvorav 3 millioner er TV-serieepisoder.
- Jeg har ikke funnet ut hvordan de fordeler seg per år.</p>
-
-<p>Hvis en fordeler på år alle tittel-IDene i IMDB som hevdes å lovlig
- kunne deles på Internett, får en følgende histogram:</p>
-
-<p align="center"><img width="80%" src="http://people.skolelinux.org/pere/blog/images/2017-12-20-histogram-year.png"></p>
-
-<p>En kan i histogrammet se at effekten av manglende registrering
- eller fornying av registrering er at mange filmer gitt ut i USA før
- 1978 er allemannseie i dag. I tillegg kan en se at det finnes flere
- filmer gitt ut de siste årene med bruksvilkår som tillater deling,
- muligens på grunn av fremveksten av
- <a href="https://creativecommons.org/">Creative
- Commons</a>-bevegelsen..</p>
-
-<p>For maskinell analyse av katalogene har jeg laget et lite program
- som kobler seg til bittorrent-katalogene som brukes av ulike Popcorn
- Time-varianter og laster ned komplett liste over filmer i
- katalogene, noe som bekrefter at det er mulig å hente ned komplett
- liste med alle filmtitler som er tilgjengelig. Jeg har sett på fire
- bittorrent-kataloger. Den ene brukes av klienten tilgjengelig fra
- www.popcorntime.sh og er navngitt 'sh' i dette dokumentet. Den
- andre brukes i følge dokument 09,12 av klienten tilgjengelig fra
- popcorntime.ag og popcorntime.sh og er navngitt 'yts' i dette
- dokumentet. Den tredje brukes av websidene tilgjengelig fra
- popcorntime-online.tv og er navngitt 'apidomain' i dette dokumentet.
- Den fjerde brukes av klienten tilgjenglig fra popcorn-time.to i
- følge dokument 09,12, og er navngitt 'ukrfnlge' i dette
- dokumentet.</p>
-
-<p>Metoden Økokrim legger til grunn skriver i sitt punkt fire at
- skjønn er en egnet metode for å finne ut om en film kan lovlig deles
- på Internett eller ikke, og sier at det ble «vurdert hvorvidt det
- var rimelig å forvente om at verket var vernet av copyright». For
- det første er det ikke nok å slå fast om en film er «vernet av
- copyright» for å vite om det er lovlig å dele den på Internett eller
- ikke, da det finnes flere filmer med opphavsrettslige bruksvilkår
- som tillater deling på Internett. Eksempler på dette er Creative
- Commons-lisensierte filmer som Citizenfour fra 2014 og Sintel fra
- 2010. I tillegg til slike finnes det flere filmer som nå er
- allemannseie (public domain) på grunn av manglende registrering
- eller fornying av registrering selv om både regisør,
- produksjonsselskap og distributør ønsker seg vern. Eksempler på
- dette er Plan 9 from Outer Space fra 1959 og Night of the Living
- Dead fra 1968. Alle filmer fra USA som var allemannseie før
- 1989-03-01 forble i det fri da Bern-konvensjonen, som tok effekt i
- USA på det tidspunktet, ikke ble gitt tilbakevirkende kraft. Hvis
- det er noe
- <a href="http://www.latimes.com/local/lanow/la-me-ln-happy-birthday-song-lawsuit-decision-20150922-story.html">historien
- om sangen «Happy birthday»</a> forteller oss, der betaling for bruk
- har vært krevd inn i flere tiår selv om sangen ikke egentlig var
- vernet av åndsverksloven, så er det at hvert enkelt verk må vurderes
- nøye og i detalj før en kan slå fast om verket er allemannseie eller
- ikke, det holder ikke å tro på selverklærte rettighetshavere. Flere
- eksempel på verk i det fri som feilklassifiseres som vernet er fra
- dokument 09,18, som lister opp søkeresultater for klienten omtalt
- som popcorntime.sh og i følge notatet kun inneholder en film (The
- Circus fra 1928) som under tvil kan antas å være allemannseie.</p>
-
-<p>Ved rask gjennomlesning av dokument 09,18, som inneholder
- skjermbilder fra bruk av en Popcorn Time-variant, fant jeg omtalt
- både filmen «The Brain That Wouldn't Die» fra 1962 som er
- <a href="https://archive.org/details/brain_that_wouldnt_die">tilgjengelig
- fra Internett-arkivet</a> og som
- <a href="https://en.wikipedia.org/wiki/List_of_films_in_the_public_domain_in_the_United_States">i
- følge Wikipedia er allemannseie i USA</a> da den ble gitt ut i
- 1962 uten 'copyright'-merking, og filmen «God’s Little Acre» fra
- 1958 <a href="https://en.wikipedia.org/wiki/God%27s_Little_Acre_%28film%29">som
- er lagt ut på Wikipedia</a>, der det fortelles at
- sort/hvit-utgaven er allemannseie. Det fremgår ikke fra dokument
- 09,18 om filmen omtalt der er sort/hvit-utgaven. Av
- kapasitetsårsaker og på grunn av at filmoversikten i dokument 09,18
- ikke er maskinlesbart har jeg ikke forsøkt å sjekke alle filmene som
- listes opp der om mot liste med filmer som er antatt lovlig kan
- distribueres på Internet.</p>
-
-<p>Ved maskinell gjennomgang av listen med IMDB-referanser under
- regnearkfanen 'Unique titles' i dokument 09.14, fant jeg i tillegg
- filmen «She Wore a Yellow Ribbon» fra 1949) som nok også er
- feilklassifisert. Filmen «She Wore a Yellow Ribbon» er tilgjengelig
- fra Internett-arkivet og markert som allemannseie der. Det virker
- dermed å være minst fire ganger så mange filmer som kan lovlig deles
- på Internett enn det som er lagt til grunn når en påstår at minst
- 99% av innholdet er ulovlig. Jeg ser ikke bort fra at nærmere
- undersøkelser kan avdekke flere. Poenget er uansett at metodens
- punkt om «rimelig å forvente om at verket var vernet av copyright»
- gjør metoden upålitelig.</p>
-
-<p>Den omtalte målemetoden velger ut tilfeldige søketermer fra
- ordlisten Dale-Chall. Den ordlisten inneholder 3000 enkle engelske
- som fjerdeklassinger i USA er forventet å forstå. Det fremgår ikke
- hvorfor akkurat denne ordlisten er valgt, og det er uklart for meg
- om den er egnet til å få et representativt utvalg av filmer. Mange
- av ordene gir tomt søkeresultat. Ved å simulerte tilsvarende søk
- ser jeg store avvik fra fordelingen i katalogen for enkeltmålinger.
- Dette antyder at enkeltmålinger av 100 filmer slik målemetoden
- beskriver er gjort, ikke er velegnet til å finne andel ulovlig
- innhold i bittorrent-katalogene.</p>
-
-<p>En kan motvirke dette store avviket for enkeltmålinger ved å gjøre
- mange søk og slå sammen resultatet. Jeg har testet ved å
- gjennomføre 100 enkeltmålinger (dvs. måling av (100x100=) 10 000
- tilfeldig valgte filmer) som gir mindre, men fortsatt betydelig
- avvik, i forhold til telling av filmer pr år i hele katalogen.</p>
-
-<p>Målemetoden henter ut de fem øverste i søkeresultatet.
- Søkeresultatene er sortert på antall bittorrent-klienter registrert
- som delere i katalogene, hvilket kan gi en slagside mot hvilke
- filmer som er populære blant de som bruker bittorrent-katalogene,
- uten at det forteller noe om hvilket innhold som er tilgjengelig
- eller hvilket innhold som deles med Popcorn Time-klienter. Jeg har
- forsøkt å måle hvor stor en slik slagside eventuelt er ved å
- sammenligne fordelingen hvis en tar de 5 nederste i søkeresultatet i
- stedet. Avviket for disse to metodene for endel kataloger er godt
- synlig på histogramet. Her er histogram over filmer funnet i den
- komplette katalogen (grønn strek), og filmer funnet ved søk etter
- ord i Dale-Chall. Grafer merket 'top' henter fra de 5 første i
- søkeresultatet, mens de merket 'bottom' henter fra de 5 siste. En
- kan her se at resultatene påvirkes betydelig av hvorvidt en ser på
- de første eller de siste filmene i et søketreff.</p>

-
-<p>Det er verdt å bemerke at de omtalte bittorrent-katalogene ikke er
- laget for bruk med Popcorn Time. Eksempelvis tilhører katalogen
- YTS, som brukes av klientet som ble lastes ned fra popcorntime.sh,
- et selvstendig fildelings-relatert nettsted YTS.AG med et separat
- brukermiljø. Målemetoden foreslått av Økokrim måler dermed ikke
- (u)lovligheten rundt bruken av Popcorn Time, men (u)lovligheten til
- innholdet i disse katalogene.</p>

-
-<p><strong>1.1. Methodology</strong>
-
-<p>Due to its technical configuration, Popcorn Time applications don't

-evaluate the level of illegal operation of PCT, the following
-methodology was applied:</p>
-
-<ol>
-
- <li>A random selection of 50 keywords, greater than 3 letters, was
- made from the Dale-Chall list that contains 3000 simple English
- words1. The selection was made by using a Random Number
- Generator2.</li>
-
- <li>For each keyword, starting with the first randomly selected
- keyword, a search query was conducted in the movie section of the
- respective Popcorn Time application. For each keyword, the first
- five results were added to the title list until the number of 100
- unique titles was reached (duplicates were removed).</li>
-
- <li>For one fork, .CH, insufficient titles were generated via this
- approach to reach 100 titles. This was solved by adding any
- additional query results above five for each of the 50 keywords.
- Since this still was not enough, another 42 random keywords were
- selected to finally reach 100 titles.</li>
-
- <li>It was verified whether or not there is a reasonable expectation
- that the work is copyrighted by checking if they are available on
- IMDb, also verifying the director, the year when the title was
- released, the release date for a certain market, the production
- company/ies of the title and the distribution company/ies.</li>

-<p><strong>1.2. Results</strong></p>
-
-<p>Between 6 and 9 June 2016, four forks of Popcorn Time were
-investigated: popcorn-time.to, popcorntime.ag, popcorntime.sh and
-popcorntime.ch. An excel sheet with the results is included in
-Appendix 1. Screenshots were secured in separate Appendixes for each
-respective fork, see Appendix 2-5.</p>
-
-<p>For each fork, out of 100, de-duplicated titles it was possible to
-retrieve data according to the parameters set out above that indicate
-that the title is commercially available. Per fork, there was 1 title
-that presumably falls within the public domain, i.e. the 1928 movie
-"The Circus" by and with Charles Chaplin.</p>
-
-<p>Based on the above it is reasonable to assume that 99% of the movie
-content of each fork is copyright protected and is made available
-illegally.</p>
-
-<p>This exercise was not repeated for TV series, but considering that
-besides production companies and distribution companies also
-broadcasters may have relevant rights, it is reasonable to assume that
-at least a similar level of infringement will be established.</p>
-
-<p>Based on the above it is reasonable to assume that 99% of all the
-content of each fork is copyright protected and are made available
-illegally.</p>

+ <description><p>I continue to explore my Kodi installation, and today I wanted to
+tell it to play a youtube URL I received in a chat, without having to
+insert search terms using the on-screen keyboard. After searching the
+web for API access to the Youtube plugin and testing a bit, I managed
+to find a recipe that worked. If you got a kodi instance with its API
+available from http://kodihost/jsonrpc, you can try the following to
+have check out a nice cover band.</p>
+
+<p><blockquote><pre>curl --silent --header 'Content-Type: application/json' \
+ --data-binary '{ "id": 1, "jsonrpc": "2.0", "method": "Player.Open",
+ "params": {"item": { "file":
+ "plugin://plugin.video.youtube/play/?video_id=LuRGVM9O0qg" } } }' \
+ http://projector.local/jsonrpc</pre></blockquote></p>
+
+<p>I've extended kodi-stream program to take a video source as its
+first argument. It can now handle direct video links, youtube links
+and 'desktop' to stream my desktop to Kodi. It is almost like a
+Chromecast. :)</p>
+
+<p>As usual, if you use Bitcoin and want to show your support of my
+activities, please send Bitcoin donations to my address

- <title>Cura, the nice 3D print slicer, is now in Debian Unstable</title>

- <description><p>After several months of working and waiting, I am happy to report
-that the nice and user friendly 3D printer slicer software Cura just
-entered Debian Unstable. It consist of five packages,
-<a href="https://tracker.debian.org/pkg/cura">cura</a>,
-<a href="https://tracker.debian.org/pkg/cura-engine">cura-engine</a>,
-<a href="https://tracker.debian.org/pkg/libarcus">libarcus</a>,
-<a href="https://tracker.debian.org/pkg/fdm-materials">fdm-materials</a>,
-<a href="https://tracker.debian.org/pkg/libsavitar">libsavitar</a> and
-<a href="https://tracker.debian.org/pkg/uranium">uranium</a>. The last
-two, uranium and cura, entered Unstable yesterday. This should make
-it easier for Debian users to print on at least the Ultimaker class of
-3D printers. My nearest 3D printer is an Ultimaker 2+, so it will
-make life easier for at least me. :)</p>
-
-<p>The work to make this happen was done by Gregor Riepl, and I was
-happy to assist him in sponsoring the packages. With the introduction
-of Cura, Debian is up to three 3D printer slicers at your service,
-Cura, Slic3r and Slic3r Prusa. If you own or have access to a 3D
-printer, give it a go. :)</p>
-
-<p>The 3D printer software is maintained by the 3D printer Debian
-team, flocking together on the
-<a href="http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/3dprinter-general">3dprinter-general</a>
-mailing list and the
-<a href="irc://irc.debian.org/#debian-3dprinting">#debian-3dprinting</a>
-IRC channel.</p>
-
-<p>The next step for Cura in Debian is to update the cura package to
-version 3.0.3 and then update the entire set of packages to version
-3.1.0 which showed up the last few days.</p>

+ <description><p>It might seem obvious that software created using tax money should
+be available for everyone to use and improve. Free Software
+Foundation Europe recentlystarted a campaign to help get more people
+to understand this, and I just signed the petition on
+<a href="https://publiccode.eu/">Public Money, Public Code</a> to help
+them. I hope you too will do the same.</p>
