</a>
32 <p>Recently, I needed to automatically check the copyright status of a
33 set of
<a href=
"http://www.imdb.com/">The Internet Movie database
34 (IMDB)
</a> entries, to figure out which one of the movies they refer
35 to can be freely distributed on the Internet. This proved to be
36 harder than it sounds. IMDB for sure list movies without any
37 copyright protection, where the copyright protection has expired or
38 where the movie is lisenced using a permissive license like one from
39 Creative Commons. These are mixed with copyright protected movies,
40 and there seem to be no way to separate these classes of movies using
41 the information in IMDB.
</p>
43 <p>First I tried to look up entries manually in IMDB,
44 <a href=
"https://www.wikipedia.org/">Wikipedia
</a> and
45 <a href=
"https://www.archive.org/">The Internet Archive
</a>, to get a
46 feel how to do this. It is hard to know for sure using these sources,
47 but it should be possible to be reasonable confident a movie is "out
48 of copyright" with a few hours work per movie. As I needed to check
49 almost
20,
000 entries, this approach was not sustainable. I simply
50 can not work around the clock for about
6 years to check this data
53 <p>I asked the people behind The Internet Archive if they could
54 introduce a new metadata field in their metadata XML for IMDB ID, but
55 was told that they leave it completely to the uploaders to update the
56 metadata. Some of the metadata entries had IMDB links in the
57 description, but I found no way to download all metadata files in bulk
58 to locate those ones and put that approach aside.
</p>
60 <p>In the process I noticed several Wikipedia articles about movies
61 had links to both IMDB and The Internet Archive, and it occured to me
62 that I could use the Wikipedia RDF data set to locate entries with
63 both, to at least get a lower bound on the number of movies on The
64 Internet Archive with a IMDB ID. This is useful based on the
65 assumption that movies distributed by The Internet Archive can be
66 legally distributed on the Internet. With some help from the RDF
67 community (thank you DanC), I was able to come up with this query to
68 pass to
<a href=
"https://query.wikidata.org/">the SPARQL interface on
72 SELECT ?work ?imdb ?ia ?when ?label
75 ?work wdt:P31/wdt:P279* wd:Q11424.
80 ?work rdfs:label ?label.
81 FILTER(LANG(?label) = "en").
86 <p>If I understand the query right, for every film entry anywhere in
87 Wikpedia, it will return the IMDB ID and The Internet Archive ID, and
88 when the movie was released and its English title, if either or both
89 of the latter two are available. At the moment the result set contain
90 2338 entries. Of course, it depend on volunteers including both
91 correct IMDB and The Internet Archive IDs in the wikipedia articles
92 for the movie. It should be noted that the result will include
93 duplicates if the movie have entries in several languages. There are
94 some bogus entries, either because The Internet Archive ID contain a
95 typo or because the movie is not available from The Internet Archive.
96 I did not verify the IMDB IDs, as I am unsure how to do that
99 <p>I wrote a small python script to extract the data set from Wikidata
100 and check if the XML metadata for the movie is available from The
101 Internet Archive, and after around
1.5 hour it produced a list of
2097
102 free movies and their IMDB ID. In total,
171 entries in Wikidata lack
103 the refered Internet Archive entry. I assume the
60 "disappearing"
104 entries (ie
2338-
2097-
171) are duplicate entries.
</p>
106 <p>This is not too bad, given that The Internet Archive report to
107 contain
<a href=
"https://archive.org/details/feature_films">5331
108 feature films
</a> at the moment, but it also mean more than
3000
109 movies are missing on Wikipedia or are missing the pair of references
112 <p>I was curious about the distribution by release year, and made a
113 little graph to show how the amount of free movies is spread over the
116 <p><img src=
"http://people.skolelinux.org/pere/blog/images/2017-10-25-verk-i-det-fri-filmer.png"></p>
118 <p>I expect the relative distribution of the remaining
3000 movies to
121 <p>If you want to help, and want to ensure Wikipedia can be used to
122 cross reference The Internet Archive and The Internet Movie Database,
123 please make sure entries like this are listed under the "External
124 links" heading on the Wikipedia article for the movie:
</p>
127 * {{Internet Archive film|id=FightingLady}}
128 * {{IMDb title|id=
0036823|title=The Fighting Lady}}
131 <p>Please verify the links on the final page, to make sure you did not
132 introduce a typo.

</a>
327 <p>I find it fascinating how many of the people being locked inside
328 the proposed border wall between USA and Mexico support the idea. The
329 proposal to keep Mexicans out reminds me of
330 <a href=
"http://www.history.com/news/10-things-you-may-not-know-about-the-berlin-wall">the
331 propaganda twist from the East Germany government
</a> calling the wall
332 the “Antifascist Bulwark” after erecting the Berlin Wall, claiming
333 that the wall was erected to keep enemies from creeping into East
334 Germany, while it was obvious to the people locked inside it that it
335 was erected to keep the people from escaping.
</p>
337 <p>Do the people in USA supporting this wall really believe it is a
338 one way wall, only keeping people on the outside from getting in,
339 while not keeping people in the inside from getting out?

3D prints in Debian using Cura and Slic3r(-prusa)
</a>
360 <p>At my nearby maker space,
361 <a href=
"http://sonen.ifi.uio.no/">Sonen
</a>, I heard the story that it
362 was easier to generate gcode files for theyr
3D printers (Ultimake
2+)
363 on Windows and MacOS X than Linux, because the software involved had
364 to be manually compiled and set up on Linux while premade packages
365 worked out of the box on Windows and MacOS X. I found this annoying,
366 as the software involved,
367 <a href=
"https://github.com/Ultimaker/Cura">Cura
</a>, is free software
368 and should be trivial to get up and running on Linux if someone took
369 the time to package it for the relevant distributions. I even found
370 <a href=
"https://bugs.debian.org/706656">a request for adding into
371 Debian
</a> from
2013, which had seem some activity over the years but
372 never resulted in the software showing up in Debian. So a few days
373 ago I offered my help to try to improve the situation.
</p>
375 <p>Now I am very happy to see that all the packages required by a
376 working Cura in Debian are uploaded into Debian and waiting in the NEW
377 queue for the ftpmasters to have a look. You can track the progress
379 <a href=
"https://qa.debian.org/developer.php?email=3dprinter-general%40lists.alioth.debian.org">the
380 status page for the
3D printer team
</a>.
</p>
382 <p>The uploaded packages are a bit behind upstream, and was uploaded
383 now to get slots in
<a href=
"https://ftp-master.debian.org/new.html">the NEW
384 queue
</a> while we work up updating the packages to the latest
385 upstream version.
</p>
387 <p>On a related note, two competitors for Cura, which I found harder
388 to use and was unable to configure correctly for Ultimaker
2+ in the
389 short time I spent on it, are already in Debian. If you are looking
390 for
3D printer "slicers" and want something already available in
392 <a href=
"https://tracker.debian.org/pkg/slic3r">slic3r
</a> and
393 <a href=
"https://tracker.debian.org/pkg/slic3r-prusa">slic3r-prusa
</a>.
394 The latter is a fork of the former.

</a>
415 Når jeg holder på med ulike prosjekter, så trenger jeg stadig ulike
416 skruer. Det siste prosjektet jeg holder på med er å lage
417 <a href=
"https://www.thingiverse.com/thing:676916">en boks til en
418 HDMI-touch-skjerm
</a> som skal brukes med Raspberry Pi. Boksen settes
419 sammen med skruer og bolter, og jeg har vært i tvil om hvor jeg kan
420 få tak i de riktige skruene. Clas Ohlson og Jernia i nærheten har
421 sjelden hatt det jeg trenger. Men her om dagen fikk jeg et fantastisk
422 tips for oss som bor i Oslo.
423 <a href=
"http://www.zachskruer.no/">Zachariassen Jernvare AS
</a> i
424 <a href=
"http://www.openstreetmap.org/?mlat=59.93421&mlon=10.76795#map=19/59.93421/10.76795">Hegermannsgate
425 23A på Torshov
</a> har et fantastisk utvalg, og åpent mellom
09:
00 og
426 17:
00. De selger skruer, muttere, bolter, skiver etc i løs vekt, og
427 så langt har jeg fått alt jeg har lett etter. De har i tillegg det
428 meste av annen jernvare, som verktøy, lamper, ledninger, etc. Jeg
429 håper de har nok kunder til å holde det gående lenge, da dette er en
430 butikk jeg kommer til å besøke ofte. Butikken er et funn å ha i
431 nabolaget for oss som liker å bygge litt selv. :)
