- <div class="date">28th November 2017</div>
- <div class="body"><p>It would be easier to locate the movie you want to watch in
-<a href="https://www.archive.org/">the Internet Archive</a>, if the
-metadata about each movie was more complete and accurate. In the
-archiving community, a well known saying state that good metadata is a
-love letter to the future. The metadata in the Internet Archive could
-use a face lift for the future to love us back. Here is a proposal
-for a small improvement that would make the metadata more useful
-today. I've been unable to find any document describing the various
-standard fields available when uploading videos to the archive, so
-this proposal is based on my best quess and searching through several
-of the existing movies.</p>
-
-<p>I have a few use cases in mind. First of all, I would like to be
-able to count the number of distinct movies in the Internet Archive,
-without duplicates. I would further like to identify the IMDB title
-ID of the movies in the Internet Archive, to be able to look up a IMDB
-title ID and know if I can fetch the video from there and share it
-with my friends.</p>
-
-<p>Second, I would like the Butter data provider for The Internet
-archive
-(<a href="https://github.com/butterproviders/butter-provider-archive">available
-from github</a>), to list as many of the good movies as possible. The
-plugin currently do a search in the archive with the following
-parameters:</p>
-
-<p><pre>
-collection:moviesandfilms
-AND NOT collection:movie_trailers
-AND -mediatype:collection
-AND format:"Archive BitTorrent"
-AND year
-</pre></p>
-
-<p>Most of the cool movies that fail to show up in Butter do so
-because the 'year' field is missing. The 'year' field is populated by
-the year part from the 'date' field, and should be when the movie was
-released (date or year). Two such examples are
-<a href="https://archive.org/details/SidneyOlcottsBen-hur1905">Ben Hur
-from 1905</a> and
-<a href="https://archive.org/details/Caminandes2GranDillama">Caminandes
-2: Gran Dillama from 2013</a>, where the year metadata field is
-missing.</p>
-
-So, my proposal is simply, for every movie in The Internet Archive
-where an IMDB title ID exist, please fill in these metadata fields
-(note, they can be updated also long after the video was uploaded, but
-as far as I can tell, only by the uploader):
-
-<dl>
-
-<dt>mediatype</dt>
-<dd>Should be 'movie' for movies.</dd>
-
-<dt>collection</dt>
-<dd>Should contain 'moviesandfilms'.</dd>
-
-<dt>title</dt>
-<dd>The title of the movie, without the publication year.</dd>
-
-<dt>date</dt>
-<dd>The data or year the movie was released. This make the movie show
-up in Butter, as well as make it possible to know the age of the
-movie and is useful to figure out copyright status.</dd>
-
-<dt>director</dt>
-<dd>The director of the movie. This make it easier to know if the
-correct movie is found in movie databases.</dd>
-
-<dt>publisher</dt>
-<dd>The production company making the movie. Also useful for
-identifying the correct movie.</dd>
-
-<dt>links</dt>
-
-<dd>Add a link to the IMDB title page, for example like this: <a
-href="http://www.imdb.com/title/tt0028496/">Movie in
-IMDB</a>. This make it easier to find duplicates and allow for
-counting of number of unique movies in the Archive. Other external
-references, like to TMDB, could be added like this too.</dd>
-
-</dl>
-
-<p>I did consider proposing a Custom field for the IMDB title ID (for
-example 'imdb_title_url', 'imdb_code' or simply 'imdb', but suspect it
-will be easier to simply place it in the links free text field.</p>
-
-<p>I created
-<a href="https://github.com/petterreinholdtsen/public-domain-free-imdb">a
-list of IMDB title IDs for several thousand movies in the Internet
-Archive</a>, but I also got a list of several thousand movies without
-such IMDB title ID (and quite a few duplicates). It would be great if
-this data set could be integrated into the Internet Archive metadata
-to be available for everyone in the future, but with the current
-policy of leaving metadata editing to the uploaders, it will take a
-while before this happen. If you have uploaded movies into the
-Internet Archive, you can help. Please consider following my proposal
-above for your movies, to ensure that movie is properly
-counted. :)</p>
-
-<p>The list is mostly generated using wikidata, which based on
-Wikipedia articles make it possible to link between IMDB and movies in
-the Internet Archive. But there are lots of movies without a
-Wikipedia article, and some movies where only a collection page exist
-(like for <a href="https://en.wikipedia.org/wiki/Caminandes">the
-Caminandes example above</a>, where there are three movies but only
-one Wikidata entry).</p>

+ <div class="date">15th January 2019</div>
+ <div class="body"><p>The layered video playout server created by Sveriges Television,
+<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
+month ago, but the work upstream to prepare it for Debian started more
+than two and a half month ago. So far
+<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
+the <a href="https://tracker.debian.org/pkg/fdk-aac">non-free fdk-aac
+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
+Debian first.</p>

- <div class="date">18th November 2017</div>
- <div class="body"><p>A month ago, I blogged about my work to
-<a href="http://people.skolelinux.org/pere/blog/Locating_IMDB_IDs_of_movies_in_the_Internet_Archive_using_Wikidata.html">automatically
-check the copyright status of IMDB entries</a>, and try to count the
-number of movies listed in IMDB that is legal to distribute on the
-Internet. I have continued to look for good data sources, and
-identified a few more. The code used to extract information from
-various data sources is available in
-<a href="https://github.com/petterreinholdtsen/public-domain-free-imdb">a
-git repository</a>, currently available from github.</p>
-
-<p>So far I have identified 3186 unique IMDB title IDs. To gain
-better understanding of the structure of the data set, I created a
-histogram of the year associated with each movie (typically release
-year). It is interesting to notice where the peaks and dips in the
-graph are located. I wonder why they are placed there. I suspect
-World War II caused the dip around 1940, but what caused the peak
-around 2010?</p>
-
-<p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2017-11-18-verk-i-det-fri-filmer.png" /></p>
-
-<p>I've so far identified ten sources for IMDB title IDs for movies in
-the public domain or with a free license. This is the statistics
-reported when running 'make stats' in the git repository:</p>
-
-<pre>
- 249 entries ( 6 unique) with and 288 without IMDB title ID in free-movies-archive-org-butter.json
- 2301 entries ( 540 unique) with and 0 without IMDB title ID in free-movies-archive-org-wikidata.json
- 830 entries ( 29 unique) with and 0 without IMDB title ID in free-movies-icheckmovies-archive-mochard.json
- 2109 entries ( 377 unique) with and 0 without IMDB title ID in free-movies-imdb-pd.json
- 291 entries ( 122 unique) with and 0 without IMDB title ID in free-movies-letterboxd-pd.json
- 144 entries ( 135 unique) with and 0 without IMDB title ID in free-movies-manual.json
- 350 entries ( 1 unique) with and 801 without IMDB title ID in free-movies-publicdomainmovies.json
- 4 entries ( 0 unique) with and 124 without IMDB title ID in free-movies-publicdomainreview.json
- 698 entries ( 119 unique) with and 118 without IMDB title ID in free-movies-publicdomaintorrents.json
- 8 entries ( 8 unique) with and 196 without IMDB title ID in free-movies-vodo.json
- 3186 unique IMDB title IDs in total
-</pre>
-
-<p>The entries without IMDB title ID are candidates to increase the
-data set, but might equally well be duplicates of entries already
-listed with IMDB title ID in one of the other sources, or represent
-movies that lack a IMDB title ID. I've seen examples of all these
-situations when peeking at the entries without IMDB title ID. Based
-on these data sources, the lower bound for movies listed in IMDB that
-are legal to distribute on the Internet is between 3186 and 4713.
-
-<p>It would be great for improving the accuracy of this measurement,
-if the various sources added IMDB title ID to their metadata. I have
-tried to reach the people behind the various sources to ask if they
-are interested in doing this, without any replies so far. Perhaps you
-can help me get in touch with the people behind VODO, Public Domain
-Torrents, Public Domain Movies and Public Domain Review to try to
-convince them to add more metadata to their movie entries?</p>
-
-<p>Another way you could help is by adding pages to Wikipedia about
-movies that are legal to distribute on the Internet. If such page
-exist and include a link to both IMDB and The Internet Archive, the
-script used to generate free-movies-archive-org-wikidata.json should
-pick up the mapping as soon as wikidata is updates.</p>

+ <div class="body"><p>A fun way to learn how to program
+<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
+this module</a> to Debian two weeks ago, and as soon as it clears the
+FTP masters NEW queue, learning to program Python with Minetest on
+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
+working with a standalone Minecraft server setup. Are there any
+options to use with the normal desktop version?</p>

-
-<p>There are two commercial services available,

-<a href="https://overleaf.com">Overleaf</a>. They are very easy to
-use. Just start a new document, select which publisher to write for

-have announced their intention to join forces, so soon it will only be
-one joint service. I've used both for different documents, and they
-work just fine. While
-<a href="https://github.com/sharelatex/sharelatex">ShareLaTeX is free
-software</a>, while the latter is not. According to <a
-href="https://www.overleaf.com/help/17-is-overleaf-open-source">a

-base maintained as free software.</p>
-
-But these two are not the only alternatives.
-<a href="https://app.fiduswriter.org/">Fidus Writer</a> is another free
-software solution with <a href="https://github.com/fiduswriter">the
-source available on github</a>. I have not used it myself. Several
-others can be found on the nice

-
-<p>If you like Google Docs or Etherpad, but would like to write

+følger:</p>
+
+<p><blockquote>
+Enhver har rett til å bevege seg fritt og til fritt å velge
+oppholdssted innenfor en stats grenser.
+</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
+bevegelser, hvor en befinner seg når, og hvem som befinner seg i
+nærheten, blir samlet inn og gjort tilgjengelig for fremmede, det være
+seg myndighetene eller private organisasjoner, så kan en ikke lenger
+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 — 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
+Dagbladet en utmerket kommentar av sin journalist John Olav Egeland om
+hvilket
+<a href="https://www.dagbladet.no/kultur/kontantlost-diktatur/70543434">kontantløst
+diktatur</a> som venter oss hvis mange nok slutter å insistere på å
+betale med kontanter. Jeg anbefaler deg å lese den.</p>

- <div class="date">25th October 2017</div>
- <div class="body"><p>Recently, I needed to automatically check the copyright status of a
-set of <a href="http://www.imdb.com/">The Internet Movie database
-(IMDB)</a> entries, to figure out which one of the movies they refer
-to can be freely distributed on the Internet. This proved to be
-harder than it sounds. IMDB for sure list movies without any
-copyright protection, where the copyright protection has expired or
-where the movie is lisenced using a permissive license like one from
-Creative Commons. These are mixed with copyright protected movies,
-and there seem to be no way to separate these classes of movies using
-the information in IMDB.</p>
-
-<p>First I tried to look up entries manually in IMDB,
-<a href="https://www.wikipedia.org/">Wikipedia</a> and
-<a href="https://www.archive.org/">The Internet Archive</a>, to get a
-feel how to do this. It is hard to know for sure using these sources,
-but it should be possible to be reasonable confident a movie is "out
-of copyright" with a few hours work per movie. As I needed to check
-almost 20,000 entries, this approach was not sustainable. I simply
-can not work around the clock for about 6 years to check this data
-set.</p>
-
-<p>I asked the people behind The Internet Archive if they could
-introduce a new metadata field in their metadata XML for IMDB ID, but
-was told that they leave it completely to the uploaders to update the
-metadata. Some of the metadata entries had IMDB links in the
-description, but I found no way to download all metadata files in bulk
-to locate those ones and put that approach aside.</p>
-
-<p>In the process I noticed several Wikipedia articles about movies
-had links to both IMDB and The Internet Archive, and it occured to me
-that I could use the Wikipedia RDF data set to locate entries with
-both, to at least get a lower bound on the number of movies on The
-Internet Archive with a IMDB ID. This is useful based on the
-assumption that movies distributed by The Internet Archive can be
-legally distributed on the Internet. With some help from the RDF
-community (thank you DanC), I was able to come up with this query to
-pass to <a href="https://query.wikidata.org/">the SPARQL interface on
-Wikidata</a>:
-
-<p><pre>
-SELECT ?work ?imdb ?ia ?when ?label
-WHERE
-{
- ?work wdt:P31/wdt:P279* wd:Q11424.
- ?work wdt:P345 ?imdb.
- ?work wdt:P724 ?ia.
- OPTIONAL {
- ?work wdt:P577 ?when.
- ?work rdfs:label ?label.
- FILTER(LANG(?label) = "en").
- }
-}
-</pre></p>
-
-<p>If I understand the query right, for every film entry anywhere in
-Wikpedia, it will return the IMDB ID and The Internet Archive ID, and
-when the movie was released and its English title, if either or both
-of the latter two are available. At the moment the result set contain
-2338 entries. Of course, it depend on volunteers including both
-correct IMDB and The Internet Archive IDs in the wikipedia articles
-for the movie. It should be noted that the result will include
-duplicates if the movie have entries in several languages. There are
-some bogus entries, either because The Internet Archive ID contain a
-typo or because the movie is not available from The Internet Archive.
-I did not verify the IMDB IDs, as I am unsure how to do that
-automatically.</p>
-
-<p>I wrote a small python script to extract the data set from Wikidata
-and check if the XML metadata for the movie is available from The
-Internet Archive, and after around 1.5 hour it produced a list of 2097
-free movies and their IMDB ID. In total, 171 entries in Wikidata lack
-the refered Internet Archive entry. I assume the 70 "disappearing"
-entries (ie 2338-2097-171) are duplicate entries.</p>
-
-<p>This is not too bad, given that The Internet Archive report to
-contain <a href="https://archive.org/details/feature_films">5331
-feature films</a> at the moment, but it also mean more than 3000
-movies are missing on Wikipedia or are missing the pair of references
-on Wikipedia.</p>
-
-<p>I was curious about the distribution by release year, and made a
-little graph to show how the amount of free movies is spread over the
-years:<p>
-
-<p><img src="http://people.skolelinux.org/pere/blog/images/2017-10-25-verk-i-det-fri-filmer.png"></p>
-
-<p>I expect the relative distribution of the remaining 3000 movies to
-be similar.</p>
-
-<p>If you want to help, and want to ensure Wikipedia can be used to
-cross reference The Internet Archive and The Internet Movie Database,
-please make sure entries like this are listed under the "External
-links" heading on the Wikipedia article for the movie:</p>
-
-<p><pre>
-* {{Internet Archive film|id=FightingLady}}
-* {{IMDb title|id=0036823|title=The Fighting Lady}}
-</pre></p>
-
-<p>Please verify the links on the final page, to make sure you did not
-introduce a typo.</p>
-
-<p>Here is the complete list, if you want to correct the 171
-identified Wikipedia entries with broken links to The Internet

+ <div class="body"><p>If you read my blog regularly, you probably know I am involved in
+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,
+but there are also some periods with
+<a href="https://www.empo.no/">EMPT TV</a> and
+<a href="https://www.p7.no/">P7</a>.

- <div class="date"> 9th October 2017</div>
- <div class="body"><p>At my nearby maker space,
-<a href="http://sonen.ifi.uio.no/">Sonen</a>, I heard the story that it
-was easier to generate gcode files for theyr 3D printers (Ultimake 2+)
-on Windows and MacOS X than Linux, because the software involved had
-to be manually compiled and set up on Linux while premade packages
-worked out of the box on Windows and MacOS X. I found this annoying,
-as the software involved,
-<a href="https://github.com/Ultimaker/Cura">Cura</a>, is free software
-and should be trivial to get up and running on Linux if someone took
-the time to package it for the relevant distributions. I even found
-<a href="https://bugs.debian.org/706656">a request for adding into
-Debian</a> from 2013, which had seem some activity over the years but
-never resulted in the software showing up in Debian. So a few days
-ago I offered my help to try to improve the situation.</p>
-
-<p>Now I am very happy to see that all the packages required by a
-working Cura in Debian are uploaded into Debian and waiting in the NEW
-queue for the ftpmasters to have a look. You can track the progress
-on
-<a href="https://qa.debian.org/developer.php?email=3dprinter-general%40lists.alioth.debian.org">the
-status page for the 3D printer team</a>.</p>
-
-<p>The uploaded packages are a bit behind upstream, and was uploaded
-now to get slots in <a href="https://ftp-master.debian.org/new.html">the NEW
-queue</a> while we work up updating the packages to the latest
-upstream version.</p>
-
-<p>On a related note, two competitors for Cura, which I found harder
-to use and was unable to configure correctly for Ultimaker 2+ in the
-short time I spent on it, are already in Debian. If you are looking
-for 3D printer "slicers" and want something already available in
-Debian, check out
-<a href="https://tracker.debian.org/pkg/slic3r">slic3r</a> and

+
+<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>

- <div class="body"><p>Every mobile phone announce its existence over radio to the nearby
-mobile cell towers. And this radio chatter is available for anyone
-with a radio receiver capable of receiving them. Details about the
-mobile phones with very good accuracy is of course collected by the
-phone companies, but this is not the topic of this blog post. The
-mobile phone radio chatter make it possible to figure out when a cell
-phone is nearby, as it include the SIM card ID (IMSI). By paying
-attention over time, one can see when a phone arrive and when it leave
-an area. I believe it would be nice to make this information more
-available to the general public, to make more people aware of how
-their phones are announcing their whereabouts to anyone that care to
-listen.</p>
-
-<p>I am very happy to report that we managed to get something
-visualizing this information up and running for
-<a href="http://norwaymakers.org/osf17">Oslo Skaperfestival 2017</a>
-(Oslo Makers Festival) taking place today and tomorrow at Deichmanske

-<a href="http://people.skolelinux.org/pere/blog/Easier_recipe_to_observe_the_cell_phones_around_you.html">simple
-recipe for listening to GSM chatter</a> I posted a few days ago, and
-will show up at the stand of <a href="http://sonen.ifi.uio.no/">Åpen
-Sone from the Computer Science department of the University of
-Oslo</a>. The presentation will show the nearby mobile phones (aka
-IMSIs) as dots in a web browser graph, with lines to the dot
-representing mobile base station it is talking to. It was working in
-the lab yesterday, and was moved into place this morning.</p>
-
-<p>We set up a fairly powerful desktop machine using Debian
-Buster/Testing with several (five, I believe) RTL2838 DVB-T receivers
-connected and visualize the visible cell phone towers using an
-<a href="https://github.com/marlow925/hopglass">English version of

-grgsm_livemon_headless processes from
-<a href="https://tracker.debian.org/pkg/gr-gsm">gr-gsm</a> converting
-the radio signal to data packages is quite CPU intensive.</p>
-
-<p>The frequencies to listen to, are identified using a slightly
-patched scan-and-livemon (to set the --args values for each receiver),
-and the Hopglass data is generated using the
-<a href="https://github.com/petterreinholdtsen/IMSI-catcher/tree/meshviewer-output">patches
-in my meshviewer-output branch</a>. For some reason we could not get
-more than four SDRs working. There is also a geographical map trying
-to show the location of the base stations, but I believe their
-coordinates are hardcoded to some random location in Germany, I
-believe. The code should be replaced with code to look up location in

+ <div class="date">21st October 2018</div>
+ <div class="body"><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>
+
+<p><pre>
+apt install vlc-plugin-bittorrent
+</pre></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>

-<a href="http://people.skolelinux.org/pere/blog/Simpler_recipe_on_how_to_make_a_simple__7_IMSI_Catcher_using_Debian.html">how
-to observe the SIM card ID (aka IMSI number) of mobile phones talking
-to nearby mobile phone base stations using Debian GNU/Linux and a
-cheap USB software defined radio</a>, and thus being able to pinpoint
-the location of people and equipment (like cars and trains) with an
-accuracy of a few kilometer. Since then we have worked to make the
-procedure even simpler, and it is now possible to do this without any
-manual frequency tuning and without building your own packages.</p>
-
-<p>The <a href="https://tracker.debian.org/pkg/gr-gsm">gr-gsm</a>
-package is now included in Debian testing and unstable, and the
-IMSI-catcher code no longer require root access to fetch and decode
-the GSM data collected using gr-gsm.</p>
-
-<p>Here is an updated recipe, using packages built by Debian and a git
-clone of two python scripts:</p>
-
-<ol>
-
-<li>Start with a Debian machine running the Buster version (aka
- testing).</li>
-
-<li>Run '<tt>apt install gr-gsm python-numpy python-scipy
- python-scapy</tt>' as root to install required packages.</li>
-
-<li>Fetch the code decoding GSM packages using '<tt>git clone
- github.com/Oros42/IMSI-catcher.git</tt>'.</li>
-
-<li>Insert USB software defined radio supported by GNU Radio.</li>
-
-<li>Enter the IMSI-catcher directory and run '<tt>python
- scan-and-livemon</tt>' to locate the frequency of nearby base
- stations and start listening for GSM packages on one of them.</li>
-
-<li>Enter the IMSI-catcher directory and run '<tt>python
- simple_IMSI-catcher.py</tt>' to display the collected information.</li>
-
-</ol>
-
-<p>Note, due to a bug somewhere the scan-and-livemon program (actually
-<a href="https://github.com/ptrkrysik/gr-gsm/issues/336">its underlying
-program grgsm_scanner</a>) do not work with the HackRF radio. It does
-work with RTL 8232 and other similar USB radio receivers you can get
-very cheaply
-(<a href="https://www.ebay.com/sch/items/?_nkw=rtl+2832">for example
-from ebay</a>), so for now the solution is to scan using the RTL radio
-and only use HackRF for fetching GSM data.</p>
-
-<p>As far as I can tell, a cell phone only show up on one of the
-frequencies at the time, so if you are going to track and count every
-cell phone around you, you need to listen to all the frequencies used.
-To listen to several frequencies, use the --numrecv argument to
-scan-and-livemon to use several receivers. Further, I am not sure if
-phones using 3G or 4G will show as talking GSM to base stations, so
-this approach might not see all phones around you. I typically see
-0-400 IMSI numbers an hour when looking around where I live.</p>
-
-<p>I've tried to run the scanner on a
-<a href="https://wiki.debian.org/RaspberryPi">Raspberry Pi 2 and 3
-running Debian Buster</a>, but the grgsm_livemon_headless process seem
-to be too CPU intensive to keep up. When GNU Radio print 'O' to
-stdout, I am told there it is caused by a buffer overflow between the
-radio and GNU Radio, caused by the program being unable to read the
-GSM data fast enough. If you see a stream of 'O's from the terminal
-where you started scan-and-livemon, you need a give the process more
-CPU power. Perhaps someone are able to optimize the code to a point
-where it become possible to set up RPi3 based GSM sniffers? I tried
-using Raspbian instead of Debian, but there seem to be something wrong
-with GNU Radio on raspbian, causing glibc to abort().</p>
