- <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>

- <title>Idea for finding all public domain movies in the USA</title>

- <description><p>While looking at
-<a href="http://onlinebooks.library.upenn.edu/cce/">the scanned copies
-for the copyright renewal entries for movies published in the USA</a>,
-an idea occurred to me. The number of renewals are so few per year, it
-should be fairly quick to transcribe them all and add references to
-the corresponding IMDB title ID. This would give the (presumably)
-complete list of movies published 28 years earlier that did _not_
-enter the public domain for the transcribed year. By fetching the
-list of USA movies published 28 years earlier and subtract the movies
-with renewals, we should be left with movies registered in IMDB that
-are now in the public domain. For the year 1955 (which is the one I
-have looked at the most), the total number of pages to transcribe is
-21. For the 28 years from 1950 to 1978, it should be in the range
-500-600 pages. It is just a few days of work, and spread among a
-small group of people it should be doable in a few weeks of spare
-time.</p>
-
-<p>A typical copyright renewal entry look like this (the first one
-listed for 1955):</p>
-
-<p><blockquote>
- ADAM AND EVIL, a photoplay in seven reels by Metro-Goldwyn-Mayer
- Distribution Corp. (c) 17Aug27; L24293. Loew's Incorporated (PWH);
- 10Jun55; R151558.
-</blockquote></p>
-
-<p>The movie title as well as registration and renewal dates are easy
-enough to locate by a program (split on first comma and look for
-DDmmmYY). The rest of the text is not required to find the movie in
-IMDB, but is useful to confirm the correct movie is found. I am not
-quite sure what the L and R numbers mean, but suspect they are
-reference numbers into the archive of the US Copyright Office.</p>
-
-<p>Tracking down the equivalent IMDB title ID is probably going to be
-a manual task, but given the year it is fairly easy to search for the
-movie title using for example
-<a href="http://www.imdb.com/find?q=adam+and+evil+1927&s=all">http://www.imdb.com/find?q=adam+and+evil+1927&s=all</a>.
-Using this search, I find that the equivalent IMDB title ID for the
-first renewal entry from 1955 is
-<a href="http://www.imdb.com/title/tt0017588/">http://www.imdb.com/title/tt0017588/</a>.</p>
-
-<p>I suspect the best way to do this would be to make a specialised
-web service to make it easy for contributors to transcribe and track
-down IMDB title IDs. In the web service, once a entry is transcribed,
-the title and year could be extracted from the text, a search in IMDB
-conducted for the user to pick the equivalent IMDB title ID right
-away. By spreading out the work among volunteers, it would also be
-possible to make at least two persons transcribe the same entries to
-be able to discover any typos introduced. But I will need help to
-make this happen, as I lack the spare time to do all of this on my
-own. If you would like to help, please get in touch. Perhaps you can
-draft a web service for crowd sourcing the task?</p>
-
-<p>Note, Project Gutenberg already have some
-<a href="http://www.gutenberg.org/ebooks/search/?query=copyright+office+renewals">transcribed
-copies of the US Copyright Office renewal protocols</a>, but I have
-not been able to find any film renewals there, so I suspect they only
-have copies of renewal for written works. I have not been able to find
-any transcribed versions of movie renewals so far. Perhaps they exist
-somewhere?</p>
-
-<p>I would love to figure out methods for finding all the public
-domain works in other countries too, but it is a lot harder. At least
-for Norway and Great Britain, such work involve tracking down the
-people involved in making the movie and figuring out when they died.
-It is hard enough to figure out who was part of making a movie, but I
-do not know how to automate such procedure without a registry of every
-person involved in making movies and their death year.</p>

+ <description><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>
