-falling rocks instead of falling water to produce electricity, and
-according to its own statements it is producing more power than it is
-using, and selling the surplus electricity to the Norwegian power
-grid.  I find the concept truly amazing.  Is this the worlds only

+<a href="https://casparcg.com/">CasparCG Server</a>, entered Debian
+today.  This completes many months of work to get the source ready to
+go into Debian.  The first upload to the Debian NEW queue happened a

+<a href="https://tracker.debian.org/pkg/casparcg-server">the
+casparcg-server package</a> is only available for amd64, but I hope
+this can be improved.  The package is in contrib because it depend on

+library</a>.  The Debian package lack support for streaming web pages
+because Debian is missing CEF, Chromium Embedded Framework.  CEF is
+wanted by several packages in Debian.  But because the Chromium source
+is <a href="https://bugs.debian.org/893448">not available as a build
+dependency</a>, it is not yet possible to upload CEF to Debian.  I
+hope this will change in the future.</p>
+
+<p>The reason I got involved is that
+<a href="https://frikanalen.no/">the Norwegian open channel
+Frikanalen</a> is starting to use CasparCG for our HD playout, and I
+would like to have all the free software tools we use to run the TV
+channel available as packages from the Debian project.  The last
+remaining piece in the puzzle is Open Broadcast Encoder, but it depend
+on quite a lot of patched libraries which would have to be included in

-<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>

+<a href="https://www.python.org/">Python</a> is to follow the
+instructions in the book
+"<a href="https://nostarch.com/programwithminecraft">Learn to program
+with Minecraft</a>", which introduces programming in Python to people
+who like to play with Minecraft.  The book uses a Python library to
+talk to a TCP/IP socket with an API accepting build instructions and
+providing information about the current players in a Minecraft world.
+The TCP/IP API was first created for the Minecraft implementation for
+Raspberry Pi, and has since been ported to some server versions of
+Minecraft.  The book contain recipes for those using Windows, MacOSX
+and Raspian.  But a little known fact is that you can follow the same
+recipes using the free software construction game
+<a href="https://minetest.net/">Minetest</a>.</p>
+
+<p>There is <a href="https://github.com/sprintingkiwi/pycraft_mod">a
+Minetest module implementing the same API</a>, making it possible to
+use the Python programs coded to talk to Minecraft with Minetest too.
+I
+<a href="https://ftp-master.debian.org/new/minetest-mod-pycraft_0.20%2Bgit20180331.0376a0a%2Bdfsg-1.html">uploaded

+Debian will be a simple 'apt install' away.  The Debian package is
+maintained as part of the Debian Games team, and
+<a href="https://salsa.debian.org/games-team/unfinished/minetest-mod-pycraft">the
+packaging rules</a> are currently located under 'unfinished' on
+Salsa.</p>
+
+<p>You will most likely need to install several of the Minetest
+modules in Debian for the examples included with the library to work
+well, as there are several blocks used by the example scripts that are
+provided via modules in Minetest.  Without the required blocks, a
+simple stone block is used instead.  My initial testing with a analog
+clock did not get gold arms as instructed in the python library, but
+instead used stone arms.</p>
+
+<p>I tried to find a way to add the API to the desktop version of
+Minecraft, but were unable to find any working recipes.  The
+<a href="https://www.epiphanydigest.com/tag/minecraft-python-api/">recipes</a>
+I <a href="https://github.com/kbsriram/mcpiapi">found</a> are only

+</blockquote></p>
+
+<p>Det er altså en menneskerett å kunne bevege seg fritt i landet.
+For å bevege seg fritt i landet, så må en kunne bevege seg uten å bli
+sporet.  Det vil i dagens samfunn innebære å bevege seg uten å legge
+igjen digitale spor og uten å være radiomerket.  Hvis en vet at ens

+bevege seg fritt.  Dette gjør at det er en forutsetning for å ha glede
+av retten til å bevege seg fritt i landet at en motstår fristelsen til
+å legge igjen digitale spor når en betaler for seg.  Rettigheter som
+ikke blir brukt, blir fjernet.  Den eneste måten i dag å unngå å legge
+igjen digitale spor når en betaler for seg, er å betale med kontanter,
+samt takke nei til å legge igjen navn og adresse (slik f.eks. Elkjøp
+ber om &mdash; jeg sier de kan legge inn «anonym anonym» når
+datasystemet deres trenger et navn).  Personlig anbefaler jeg å
+konsekvent bruke kontant betaling når man beveger seg rundt, for å
+bidra til forsvaret av menneskerettighetene i Norge.  Kanskje noe også
+for deg?  Merk at det ikke er tilstrekkelig for å unngå sporing å
+betale med kontanter, men det er et lite steg i riktig retning.</p>
+
+<p>Det er flere andre argumenter i tillegg til
+menneskerettighetsargumentet for å bruke kontanter.  I går hadde

+Billions of Security Reports</a>".  I had not heard of the
+<a href="https://en.wikipedia.org/wiki/Content_Security_Policy">Content
+Security Policy standard</a> nor its ability to "call home" when a
+browser detect a policy breach (I do not follow web page design
+development much these days), and found the talk very illuminating.</p>
+
+<p>The mechanism allow a web site owner to use HTTP headers to tell
+visitors web browser which sources (internal and external) are allowed to
+be used on the web site.  Thus it become possible to enforce a "only
+local content" policy despite web designers urge to fetch programs
+from random sites on the Internet, like the one
+<a href="https://securityaffairs.co/wordpress/68966/hacking/browsealoud-plugin-hack.html">enabling
+the attack</a> reported by Scott Helme earlier this year.</p>
+
+<p>Using CSP seem like an obvious thing for a site admin to implement
+to take some control over the information leak that occur when
+external sources are used to render web pages, it is a mystery more
+sites are not using CSP?  It is being
+<a href="https://www.w3.org/TR/CSP/">standardized under W3C</a> these
+days, and is supposed by most web browsers</p>
+
+<p>I managed to find <a href="https://github.com/mozilla/django-csp">a
+Django middleware for implementing CSP</a> and was happy to discover
+it was already in Debian.  I plan to use it to add CSP support to the
+Frikanalen web site soon.</p>

+running and developing the <a href="https://frikanalen.no/">Norwegian
+TV channel Frikanalen</a>.  It is an open channel, allowing everyone
+in Norway to publish videos on a TV channel with national coverage.
+You can think of it as Youtube for national television.
+In addition to distribution on RiksTV and Uninett, Frikanalen is also
+available as a Kodi addon.  The last few days I have updated the code
+to add more features.  A
+<a href="https://kodi.tv/addon/plugins-video-add-ons/frikanalen-nett-tv">new
+and improved version 0.0.3 Frikanalen addon</a> was just made
+available via the Kodi repositories.  This new version include a
+option to browse videos by category, as well as free text search
+in the video archive.  It will now also show the video duration in the
+video lists, which were missing earlier.  A new and experimental
+link to the HD video stream currently being worked on is provided, for
+those that want to see what the <a href="https://casparcg.com/">CasparCG</a>
+output look like.  The alternative is the SD video stream, generated
+using MLT.  CasparCG is controlled by our
+<a href="https://github.com/Frikanalen/mltplayout/">mltplayout
+server</a> which instead of talking to mlt is giving PLAY instructions
+to the CasparCG server when it is time to start a new program.</p>
+
+<p>By now, you are probably wondering what kind of content is being
+played on the channel.  These days, it is filled with technical
+presentations like those from <a href="https://www.nuug.no/">NUUG</a>,
+<a href="https://www.debconf.org/">Debconf</a>, Makercon, and TED,

-      <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,

-exposure a bit.</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>

+<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>

-      <div class="body"><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>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>
