                <description>&lt;p&gt;I was surprised today to learn that a friend in academia did not
know there are easily available web services available for writing
LaTeX documents as a team.  I thought it was common knowledge, but to
make sure at least my readers are aware of it, I would like to mention
these useful services for writing LaTeX documents.  Some of them even
provide a WYSIWYG editor to ease writing even further.&lt;/p&gt;

&lt;p&gt;There are two commercial services available, &lt;a
href=&quot;https://sharelatex.com&quot;&gt;ShareLaTeX&lt;/a&gt; and &lt;a
href=&quot;https://overleaf.com&quot;&gt;Overleaf&lt;/a&gt;.  They are very easy to use.
Just start a new document, select which publisher to write for (ie
which LaTeX style to use), and start writing.  Note, these two have announced their
intention to join forces, so soon it will only be one joint service.
I&#39;ve used both for different documents, and they work just fine.
While &lt;a href=&quot;https://github.com/sharelatex/sharelatex&quot;&gt;ShareLaTeX is
free software&lt;/a&gt;, while the latter is not.  According to &lt;a
href=&quot;https://www.overleaf.com/help/17-is-overleaf-open-source&quot;&gt;a
announcement from Overleaf&lt;/a&gt;, they plan to keep the ShareLaTeX code
base maintained as free software.&lt;/p&gt;

But these two are not the only alternatives.
&lt;a href=&quot;https://app.fiduswriter.org/&quot;&gt;Fidus Writer&lt;/a&gt; is another free
software solution with &lt;a href=&quot;https://github.com/fiduswriter&quot;&gt;the
source available on github&lt;/a&gt;.  I have not used it myself.  Several
others can be found on the nice
&lt;a href=&quot;https://alternativeto.net/software/sharelatex/&quot;&gt;alterntiveTo
web service&lt;/a&gt;.

&lt;p&gt;If you like Google Docs or Etherpad, but would like to write
documents in LaTeX, you should check out these services.  You can even
host your own, if you want to. :)&lt;/p&gt;

                <title>Locating IMDB IDs of movies in the Internet Archive using Wikidata</title>
                <link>http://people.skolelinux.org/pere/blog/Locating_IMDB_IDs_of_movies_in_the_Internet_Archive_using_Wikidata.html</link>        
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Locating_IMDB_IDs_of_movies_in_the_Internet_Archive_using_Wikidata.html</guid>
                <pubDate>Wed, 25 Oct 2017 12:20:00 +0200</pubDate>
                <description>&lt;p&gt;Recently, I needed to automatically check the copyright status of a
set of &lt;a href=&quot;http://www.imdb.com/&quot;&gt;The Internet Movie database
(IMDB)&lt;/a&gt; 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.&lt;/p&gt;

&lt;p&gt;First I tried to look up entries manually in IMDB,
&lt;a href=&quot;https://www.wikipedia.org/&quot;&gt;Wikipedia&lt;/a&gt; and
&lt;a href=&quot;https://www.archive.org/&quot;&gt;The Internet Archive&lt;/a&gt;, 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 &quot;out
of copyright&quot; 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.&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;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 &lt;a href=&quot;https://query.wikidata.org/&quot;&gt;the SPARQL interface on
Wikidata&lt;/a&gt;:

&lt;p&gt;&lt;pre&gt;
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) = &quot;en&quot;).
  }
}
&lt;/pre&gt;&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;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 &quot;disappearing&quot;
entries (ie 2338-2097-171) are duplicate entries.&lt;/p&gt;

&lt;p&gt;This is not too bad, given that The Internet Archive report to
contain &lt;a href=&quot;https://archive.org/details/feature_films&quot;&gt;5331
feature films&lt;/a&gt; at the moment, but it also mean more than 3000
movies are missing on Wikipedia or are missing the pair of references
on Wikipedia.&lt;/p&gt;

&lt;p&gt;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:&lt;p&gt;

&lt;p&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2017-10-25-verk-i-det-fri-filmer.png&quot;&gt;&lt;/p&gt;

&lt;p&gt;I expect the relative distribution of the remaining 3000 movies to
be similar.&lt;/p&gt;

&lt;p&gt;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 &quot;External
links&quot; heading on the Wikipedia article for the movie:&lt;/p&gt;

&lt;p&gt;&lt;pre&gt;
* {{Internet Archive film|id=FightingLady}}
* {{IMDb title|id=0036823|title=The Fighting Lady}}
&lt;/pre&gt;&lt;/p&gt;

&lt;p&gt;Please verify the links on the final page, to make sure you did not
introduce a typo.&lt;/p&gt;

&lt;p&gt;Here is the complete list, if you want to correct the 171
identified Wikipedia entries with broken links to The Internet
Archive: &lt;a href=&quot;http://www.wikidata.org/entity/Q1140317&quot;&gt;Q1140317&lt;/a&gt;,

                <description>&lt;p&gt;I find it fascinating how many of the people being locked inside
the proposed border wall between USA and Mexico support the idea.  The
proposal to keep Mexicans out reminds me of
&lt;a href=&quot;http://www.history.com/news/10-things-you-may-not-know-about-the-berlin-wall&quot;&gt;the
propaganda twist from the East Germany government&lt;/a&gt; calling the wall
the “Antifascist Bulwark” after erecting the Berlin Wall, claiming
that the wall was erected to keep enemies from creeping into East
Germany, while it was obvious to the people locked inside it that it
was erected to keep the people from escaping.&lt;/p&gt;

&lt;p&gt;Do the people in USA supporting this wall really believe it is a
one way wall, only keeping people on the outside from getting in,
while not keeping people in the inside from getting out?&lt;/p&gt;

                <title>Generating 3D prints in Debian using Cura and Slic3r(-prusa)</title>
                <link>http://people.skolelinux.org/pere/blog/Generating_3D_prints_in_Debian_using_Cura_and_Slic3r__prusa_.html</link>

                <pubDate>Mon, 9 Oct 2017 10:50:00 +0200</pubDate>
                <description>&lt;p&gt;At my nearby maker space,
&lt;a href=&quot;http://sonen.ifi.uio.no/&quot;&gt;Sonen&lt;/a&gt;, 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,
&lt;a href=&quot;https://github.com/Ultimaker/Cura&quot;&gt;Cura&lt;/a&gt;, 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
&lt;a href=&quot;https://bugs.debian.org/706656&quot;&gt;a request for adding into
Debian&lt;/a&gt; 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.&lt;/p&gt;

&lt;p&gt;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
&lt;a href=&quot;https://qa.debian.org/developer.php?email=3dprinter-general%40lists.alioth.debian.org&quot;&gt;the
status page for the 3D printer team&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;The uploaded packages are a bit behind upstream, and was uploaded
now to get slots in &lt;a href=&quot;https://ftp-master.debian.org/new.html&quot;&gt;the NEW
queue&lt;/a&gt; while we work up updating the packages to the latest
upstream version.&lt;/p&gt;

&lt;p&gt;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 &quot;slicers&quot; and want something already available in
Debian, check out
&lt;a href=&quot;https://tracker.debian.org/pkg/slic3r&quot;&gt;slic3r&lt;/a&gt; and
&lt;a href=&quot;https://tracker.debian.org/pkg/slic3r-prusa&quot;&gt;slic3r-prusa&lt;/a&gt;.
The latter is a fork of the former.&lt;/p&gt;

                <description>Når jeg holder på med ulike prosjekter, så trenger jeg stadig ulike
skruer.  Det siste prosjektet jeg holder på med er å lage
&lt;a href=&quot;https://www.thingiverse.com/thing:676916&quot;&gt;en boks til en
HDMI-touch-skjerm&lt;/a&gt; som skal brukes med Raspberry Pi.  Boksen settes
sammen med skruer og bolter, og jeg har vært i tvil om hvor jeg kan
få tak i de riktige skruene.  Clas Ohlson og Jernia i nærheten har
sjelden hatt det jeg trenger.  Men her om dagen fikk jeg et fantastisk
tips for oss som bor i Oslo.
&lt;a href=&quot;http://www.zachskruer.no/&quot;&gt;Zachariassen Jernvare AS&lt;/a&gt; i
&lt;a href=&quot;http://www.openstreetmap.org/?mlat=59.93421&amp;mlon=10.76795#map=19/59.93421/10.76795&quot;&gt;Hegermannsgate
23A på Torshov&lt;/a&gt; har et fantastisk utvalg, og åpent mellom 09:00 og
17:00.  De selger skruer, muttere, bolter, skiver etc i løs vekt, og
så langt har jeg fått alt jeg har lett etter.  De har i tillegg det
meste av annen jernvare, som verktøy, lamper, ledninger, etc.  Jeg
håper de har nok kunder til å holde det gående lenge, da dette er en
butikk jeg kommer til å besøke ofte.  Butikken er et funn å ha i
nabolaget for oss som liker å bygge litt selv. :)&lt;/p&gt;
