  24       <div class="date">13th December 2017</div>
  25       <div class="body"><p>While looking at
  26 <a href="http://onlinebooks.library.upenn.edu/cce/">the scanned copies
  27 for the copyright renewal entries for movies published in the USA</a>,
  28 an idea occurred to me.  The number of renewals are so few per year, it
  29 should be fairly quick to transcribe them all and add references to
  30 the corresponding IMDB title ID.  This would give the (presumably)
  31 complete list of movies published 28 years earlier that did _not_
  32 enter the public domain for the transcribed year.  By fetching the
  33 list of USA movies published 28 years earlier and subtract the movies
  34 with renewals, we should be left with movies registered in IMDB that
  35 are now in the public domain.  For the year 1955 (which is the one I
  36 have looked at the most), the total number of pages to transcribe is
  37 21.  For the 28 years from 1950 to 1978, it should be in the range
  38 500-600 pages.  It is just a few days of work, and spread among a
  39 small group of people it should be doable in a few weeks of spare
  40 time.</p>
  41
  42 <p>A typical copyright renewal entry look like this (the first one
  43 listed for 1955):</p>
  44
  45 <p><blockquote>
  46   ADAM AND EVIL, a photoplay in seven reels by Metro-Goldwyn-Mayer
  47   Distribution Corp. (c) 17Aug27; L24293. Loew's Incorporated (PWH);
  48   10Jun55; R151558.
  49 </blockquote></p>
  50
  51 <p>The movie title as well as registration and renewal dates are easy
  52 enough to locate by a program (split on first comma and look for
  53 DDmmmYY).  The rest of the text is not required to find the movie in
  54 IMDB, but is useful to confirm the correct movie is found.  I am not
  55 quite sure what the L and R numbers mean, but suspect they are
  56 reference numbers into the archive of the US Copyright Office.</p>
  57
  58 <p>Tracking down the equivalent IMDB title ID is probably going to be
  59 a manual task, but given the year it is fairly easy to search for the
  60 movie title using for example
  61 <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>.
  62 Using this search, I find that the equivalent IMDB title ID for the
  63 first renewal entry from 1955 is
  64 <a href="http://www.imdb.com/title/tt0017588/">http://www.imdb.com/title/tt0017588/</a>.</p>
  65
  66 <p>I suspect the best way to do this would be to make a specialised
  67 web service to make it easy for contributors to transcribe and track
  68 down IMDB title IDs.  In the web service, once a entry is transcribed,
  69 the title and year could be extracted from the text, a search in IMDB
  70 conducted for the user to pick the equivalent IMDB title ID right
  71 away.  By spreading out the work among volunteers, it would also be
  72 possible to make at least two persons transcribe the same entries to
  73 be able to discover any typos introduced.  But I will need help to
  74 make this happen, as I lack the spare time to do all of this on my
  75 own.  If you would like to help, please get in touch.  Perhaps you can
  76 draft a web service for crowd sourcing the task?</p>
  77
  78 <p>Note, Project Gutenberg already have some
  79 <a href="http://www.gutenberg.org/ebooks/search/?query=copyright+office+renewals">transcribed
  80 copies of the US Copyright Office renewal protocols</a>, but I have
  81 not been able to find any film renewals there, so I suspect they only
  82 have copies of renewal for written works.  I have not been able to find
  83 any transcribed versions of movie renewals so far.  Perhaps they exist
  84 somewhere?</p>
  85
  86 <p>I would love to figure out methods for finding all the public
  87 domain works in other countries too, but it is a lot harder.  At least
  88 for Norway and Great Britain, such work involve tracking down the
  89 people involved in making the movie and figuring out when they died.
  90 It is hard enough to figure out who was part of making a movie, but I
  91 do not know how to automate such procedure without a registry of every
  92 person involved in making movies and their death year.</p>

 110       <div class="date"> 5th December 2017</div>
 111       <div class="body"><p>Three years ago, a presumed lost animation film,
 112 <a href="https://en.wikipedia.org/wiki/Empty_Socks">Empty Socks from
 113 1927</a>, was discovered in the Norwegian National Library.  At the
 114 time it was discovered, it was generally assumed to be copyrighted by
 115 The Walt Disney Company, and I blogged about
 116 <a href="http://people.skolelinux.org/pere/blog/Opphavsretts_status_for__Empty_Socks__fra_1927_.html">my
 117 reasoning to conclude</a> that it would would enter the Norwegian
 118 equivalent of the public domain in 2053, based on my understanding of
 119 Norwegian Copyright Law.  But a few days ago, I came across
 120 <a href="http://www.toonzone.net/forums/threads/exposed-disneys-repurchase-of-oswald-the-rabbit-a-sham.4792291/">a
 121 blog post claiming the movie was already in the public domain</a>, at
 122 least in USA.  The reasoning is as follows: The film was released in
 123 November or Desember 1927 (sources disagree), and presumably
 124 registered its copyright that year.  At that time, right holders of
 125 movies registered by the copyright office received government
 126 protection for there work for 28 years.  After 28 years, the copyright
 127 had to be renewed if the wanted the government to protect it further.
 128 The blog post I found claim such renewal did not happen for this
 129 movie, and thus it entered the public domain in 1956.  Yet someone
 130 claim the copyright was renewed and the movie is still copyright
 131 protected.  Can anyone help me to figure out which claim is correct?
 132 I have not been able to find Empty Socks in Catalog of copyright
 133 entries.  Ser.3 pt.12-13 v.9-12 1955-1958 Motion Pictures
 134 <a href="http://onlinebooks.library.upenn.edu/cce/1955r.html#film">available

 139 119 for the second half of 1955</a>.  It is of course possible that
 140 the renewal entry was left out of the printed catalog by mistake.  Is
 141 there some way to rule out this possibility?  Please help, and update
 142 the wikipedia page with your findings.

 159       <div class="title"><a href="http://people.skolelinux.org/pere/blog/Metadata_proposal_for_movies_on_the_Internet_Archive.html">Metadata proposal for movies on the Internet Archive</a></div>
 160       <div class="date">28th November 2017</div>
 161       <div class="body"><p>It would be easier to locate the movie you want to watch in
 162 <a href="https://www.archive.org/">the Internet Archive</a>, if the
 163 metadata about each movie was more complete and accurate.  In the
 164 archiving community, a well known saying state that good metadata is a
 165 love letter to the future.  The metadata in the Internet Archive could
 166 use a face lift for the future to love us back.  Here is a proposal
 167 for a small improvement that would make the metadata more useful
 168 today.  I've been unable to find any document describing the various
 169 standard fields available when uploading videos to the archive, so
 170 this proposal is based on my best quess and searching through several
 171 of the existing movies.</p>
 172
 173 <p>I have a few use cases in mind.  First of all, I would like to be
 174 able to count the number of distinct movies in the Internet Archive,
 175 without duplicates.  I would further like to identify the IMDB title
 176 ID of the movies in the Internet Archive, to be able to look up a IMDB
 177 title ID and know if I can fetch the video from there and share it
 178 with my friends.</p>
 179
 180 <p>Second, I would like the Butter data provider for The Internet
 181 archive
 182 (<a href="https://github.com/butterproviders/butter-provider-archive">available
 183 from github</a>), to list as many of the good movies as possible.  The
 184 plugin currently do a search in the archive with the following
 185 parameters:</p>
 186
 187 <p><pre>
 188 collection:moviesandfilms
 189 AND NOT collection:movie_trailers
 190 AND -mediatype:collection
 191 AND format:"Archive BitTorrent"
 192 AND year
 193 </pre></p>
 194
 195 <p>Most of the cool movies that fail to show up in Butter do so
 196 because the 'year' field is missing.  The 'year' field is populated by
 197 the year part from the 'date' field, and should be when the movie was
 198 released (date or year).  Two such examples are
 199 <a href="https://archive.org/details/SidneyOlcottsBen-hur1905">Ben Hur
 200 from 1905</a> and
 201 <a href="https://archive.org/details/Caminandes2GranDillama">Caminandes
 202 2: Gran Dillama from 2013</a>, where the year metadata field is
 203 missing.</p>
 204
 205 So, my proposal is simply, for every movie in The Internet Archive
 206 where an IMDB title ID exist, please fill in these metadata fields
 207 (note, they can be updated also long after the video was uploaded, but
 208 as far as I can tell, only by the uploader):
 209
 210 <dl>
 211
 212 <dt>mediatype</dt>
 213 <dd>Should be 'movie' for movies.</dd>
 214
 215 <dt>collection</dt>
 216 <dd>Should contain 'moviesandfilms'.</dd>
 217
 218 <dt>title</dt>
 219 <dd>The title of the movie, without the publication year.</dd>
 220
 221 <dt>date</dt>
 222 <dd>The data or year the movie was released.  This make the movie show
 223 up in Butter, as well as make it possible to know the age of the
 224 movie and is useful to figure out copyright status.</dd>
 225
 226 <dt>director</dt>
 227 <dd>The director of the movie.  This make it easier to know if the
 228 correct movie is found in movie databases.</dd>
 229
 230 <dt>publisher</dt>
 231 <dd>The production company making the movie.  Also useful for
 232 identifying the correct movie.</dd>
 233
 234 <dt>links</dt>
 235
 236 <dd>Add a link to the IMDB title page, for example like this: &lt;a
 237 href="http://www.imdb.com/title/tt0028496/"&gt;Movie in
 238 IMDB&lt;/a&gt;.  This make it easier to find duplicates and allow for
 239 counting of number of unique movies in the Archive.  Other external
 240 references, like to TMDB, could be added like this too.</dd>
 241
 242 </dl>
 243
 244 <p>I did consider proposing a Custom field for the IMDB title ID (for
 245 example 'imdb_title_url', 'imdb_code' or simply 'imdb', but suspect it
 246 will be easier to simply place it in the links free text field.</p>
 247
 248 <p>I created
 249 <a href="https://github.com/petterreinholdtsen/public-domain-free-imdb">a
 250 list of IMDB title IDs for several thousand movies in the Internet
 251 Archive</a>, but I also got a list of several thousand movies without
 252 such IMDB title ID (and quite a few duplicates).  It would be great if
 253 this data set could be integrated into the Internet Archive metadata
 254 to be available for everyone in the future, but with the current
 255 policy of leaving metadata editing to the uploaders, it will take a
 256 while before this happen.  If you have uploaded movies into the
 257 Internet Archive, you can help.  Please consider following my proposal
 258 above for your movies, to ensure that movie is properly
 259 counted. :)</p>
 260
 261 <p>The list is mostly generated using wikidata, which based on
 262 Wikipedia articles make it possible to link between IMDB and movies in
 263 the Internet Archive.  But there are lots of movies without a
 264 Wikipedia article, and some movies where only a collection page exist
 265 (like for <a href="https://en.wikipedia.org/wiki/Caminandes">the
 266 Caminandes example above</a>, where there are three movies but only
 267 one Wikidata entry).</p>

 285       <div class="date">18th November 2017</div>
 286       <div class="body"><p>A month ago, I blogged about my work to
 287 <a href="http://people.skolelinux.org/pere/blog/Locating_IMDB_IDs_of_movies_in_the_Internet_Archive_using_Wikidata.html">automatically
 288 check the copyright status of IMDB entries</a>, and try to count the
 289 number of movies listed in IMDB that is legal to distribute on the
 290 Internet.  I have continued to look for good data sources, and
 291 identified a few more.  The code used to extract information from
 292 various data sources is available in
 293 <a href="https://github.com/petterreinholdtsen/public-domain-free-imdb">a
 294 git repository</a>, currently available from github.</p>
 295
 296 <p>So far I have identified 3186 unique IMDB title IDs.  To gain
 297 better understanding of the structure of the data set, I created a
 298 histogram of the year associated with each movie (typically release
 299 year).  It is interesting to notice where the peaks and dips in the
 300 graph are located.  I wonder why they are placed there.  I suspect
 301 World War II caused the dip around 1940, but what caused the peak
 302 around 2010?</p>
 303
 304 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2017-11-18-verk-i-det-fri-filmer.png" /></p>
 305
 306 <p>I've so far identified ten sources for IMDB title IDs for movies in
 307 the public domain or with a free license.  This is the statistics
 308 reported when running 'make stats' in the git repository:</p>
 309
 310 <pre>
 311   249 entries (    6 unique) with and   288 without IMDB title ID in free-movies-archive-org-butter.json
 312  2301 entries (  540 unique) with and     0 without IMDB title ID in free-movies-archive-org-wikidata.json
 313   830 entries (   29 unique) with and     0 without IMDB title ID in free-movies-icheckmovies-archive-mochard.json
 314  2109 entries (  377 unique) with and     0 without IMDB title ID in free-movies-imdb-pd.json
 315   291 entries (  122 unique) with and     0 without IMDB title ID in free-movies-letterboxd-pd.json
 316   144 entries (  135 unique) with and     0 without IMDB title ID in free-movies-manual.json
 317   350 entries (    1 unique) with and   801 without IMDB title ID in free-movies-publicdomainmovies.json
 318     4 entries (    0 unique) with and   124 without IMDB title ID in free-movies-publicdomainreview.json
 319   698 entries (  119 unique) with and   118 without IMDB title ID in free-movies-publicdomaintorrents.json
 320     8 entries (    8 unique) with and   196 without IMDB title ID in free-movies-vodo.json
 321  3186 unique IMDB title IDs in total
 322 </pre>
 323
 324 <p>The entries without IMDB title ID are candidates to increase the
 325 data set, but might equally well be duplicates of entries already
 326 listed with IMDB title ID in one of the other sources, or represent
 327 movies that lack a IMDB title ID.  I've seen examples of all these
 328 situations when peeking at the entries without IMDB title ID.  Based
 329 on these data sources, the lower bound for movies listed in IMDB that
 330 are legal to distribute on the Internet is between 3186 and 4713.
 331
 332 <p>It would be great for improving the accuracy of this measurement,
 333 if the various sources added IMDB title ID to their metadata.  I have
 334 tried to reach the people behind the various sources to ask if they
 335 are interested in doing this, without any replies so far.  Perhaps you
 336 can help me get in touch with the people behind VODO, Public Domain
 337 Torrents, Public Domain Movies and Public Domain Review to try to
 338 convince them to add more metadata to their movie entries?</p>
 339
 340 <p>Another way you could help is by adding pages to Wikipedia about
 341 movies that are legal to distribute on the Internet.  If such page
 342 exist and include a link to both IMDB and The Internet Archive, the
 343 script used to generate free-movies-archive-org-wikidata.json should
 344 pick up the mapping as soon as wikidata is updates.</p>

 418 <p>Several of these research papers are based on data collected from
 419 hundred thousands or millions of disk, and their findings are eye
 420 opening.  The short story is simply do not implicitly trust RAID or
 421 redundant storage systems.  Details matter.  And unfortunately there
 422 are few options on Linux addressing all the identified issues.  Both
 423 ZFS and Btrfs are doing a fairly good job, but have legal and
 424 practical issues on their own.  I wonder how cluster file systems like
 425 Ceph do in this regard.  After all, there is an old saying, you know
 426 you have a distributed system when the crash of a computer you have
 427 never heard of stops you from getting any work done.  The same holds
 428 true if fault tolerance do not work.</p>
 429
 430 <p>Just remember, in the end, it do not matter how redundant, or how
 431 fault tolerant your storage is, if you do not continuously monitor its
 432 status to detect and replace failed disks.</p>

 451       <div class="body"><p>I was surprised today to learn that a friend in academia did not
 452 know there are easily available web services available for writing
 453 LaTeX documents as a team.  I thought it was common knowledge, but to
 454 make sure at least my readers are aware of it, I would like to mention
 455 these useful services for writing LaTeX documents.  Some of them even
 456 provide a WYSIWYG editor to ease writing even further.</p>
 457
 458 <p>There are two commercial services available,
 459 <a href="https://sharelatex.com">ShareLaTeX</a> and
 460 <a href="https://overleaf.com">Overleaf</a>.  They are very easy to
 461 use.  Just start a new document, select which publisher to write for
 462 (ie which LaTeX style to use), and start writing.  Note, these two
 463 have announced their intention to join forces, so soon it will only be
 464 one joint service.  I've used both for different documents, and they
 465 work just fine.  While
 466 <a href="https://github.com/sharelatex/sharelatex">ShareLaTeX is free
 467 software</a>, while the latter is not.  According to <a
 468 href="https://www.overleaf.com/help/17-is-overleaf-open-source">a
 469 announcement from Overleaf</a>, they plan to keep the ShareLaTeX code
 470 base maintained as free software.</p>
 471
 472 But these two are not the only alternatives.
 473 <a href="https://app.fiduswriter.org/">Fidus Writer</a> is another free
 474 software solution with <a href="https://github.com/fiduswriter">the
 475 source available on github</a>.  I have not used it myself.  Several
 476 others can be found on the nice
 477 <a href="https://alternativeto.net/software/sharelatex/">alterntiveTo
 478 web service</a>.
 479
 480 <p>If you like Google Docs or Etherpad, but would like to write
 481 documents in LaTeX, you should check out these services.  You can even
 482 host your own, if you want to. :)</p>

 500       <div class="date">25th October 2017</div>
 501       <div class="body"><p>Recently, I needed to automatically check the copyright status of a
 502 set of <a href="http://www.imdb.com/">The Internet Movie database
 503 (IMDB)</a> entries, to figure out which one of the movies they refer
 504 to can be freely distributed on the Internet.  This proved to be
 505 harder than it sounds.  IMDB for sure list movies without any
 506 copyright protection, where the copyright protection has expired or
 507 where the movie is lisenced using a permissive license like one from
 508 Creative Commons.  These are mixed with copyright protected movies,
 509 and there seem to be no way to separate these classes of movies using
 510 the information in IMDB.</p>
 511
 512 <p>First I tried to look up entries manually in IMDB,
 513 <a href="https://www.wikipedia.org/">Wikipedia</a> and
 514 <a href="https://www.archive.org/">The Internet Archive</a>, to get a
 515 feel how to do this.  It is hard to know for sure using these sources,
 516 but it should be possible to be reasonable confident a movie is "out
 517 of copyright" with a few hours work per movie.  As I needed to check
 518 almost 20,000 entries, this approach was not sustainable.  I simply
 519 can not work around the clock for about 6 years to check this data
 520 set.</p>
 521
 522 <p>I asked the people behind The Internet Archive if they could
 523 introduce a new metadata field in their metadata XML for IMDB ID, but
 524 was told that they leave it completely to the uploaders to update the
 525 metadata.  Some of the metadata entries had IMDB links in the
 526 description, but I found no way to download all metadata files in bulk
 527 to locate those ones and put that approach aside.</p>
 528
 529 <p>In the process I noticed several Wikipedia articles about movies
 530 had links to both IMDB and The Internet Archive, and it occured to me
 531 that I could use the Wikipedia RDF data set to locate entries with
 532 both, to at least get a lower bound on the number of movies on The
 533 Internet Archive with a IMDB ID.  This is useful based on the
 534 assumption that movies distributed by The Internet Archive can be
 535 legally distributed on the Internet.  With some help from the RDF
 536 community (thank you DanC), I was able to come up with this query to
 537 pass to <a href="https://query.wikidata.org/">the SPARQL interface on
 538 Wikidata</a>:
 539
 540 <p><pre>
 541 SELECT ?work ?imdb ?ia ?when ?label
 542 WHERE
 543 {
 544   ?work wdt:P31/wdt:P279* wd:Q11424.
 545   ?work wdt:P345 ?imdb.
 546   ?work wdt:P724 ?ia.
 547   OPTIONAL {
 548         ?work wdt:P577 ?when.
 549         ?work rdfs:label ?label.
 550         FILTER(LANG(?label) = "en").
 551   }
 552 }
 553 </pre></p>
 554
 555 <p>If I understand the query right, for every film entry anywhere in
 556 Wikpedia, it will return the IMDB ID and The Internet Archive ID, and
 557 when the movie was released and its English title, if either or both
 558 of the latter two are available.  At the moment the result set contain
 559 2338 entries.  Of course, it depend on volunteers including both
 560 correct IMDB and The Internet Archive IDs in the wikipedia articles
 561 for the movie.  It should be noted that the result will include
 562 duplicates if the movie have entries in several languages.  There are
 563 some bogus entries, either because The Internet Archive ID contain a
 564 typo or because the movie is not available from The Internet Archive.
 565 I did not verify the IMDB IDs, as I am unsure how to do that
 566 automatically.</p>
 567
 568 <p>I wrote a small python script to extract the data set from Wikidata
 569 and check if the XML metadata for the movie is available from The
 570 Internet Archive, and after around 1.5 hour it produced a list of 2097
 571 free movies and their IMDB ID.  In total, 171 entries in Wikidata lack
 572 the refered Internet Archive entry.  I assume the 70 "disappearing"
 573 entries (ie 2338-2097-171) are duplicate entries.</p>
 574
 575 <p>This is not too bad, given that The Internet Archive report to
 576 contain <a href="https://archive.org/details/feature_films">5331
 577 feature films</a> at the moment, but it also mean more than 3000
 578 movies are missing on Wikipedia or are missing the pair of references
 579 on Wikipedia.</p>
 580
 581 <p>I was curious about the distribution by release year, and made a
 582 little graph to show how the amount of free movies is spread over the
 583 years:<p>
 584
 585 <p><img src="http://people.skolelinux.org/pere/blog/images/2017-10-25-verk-i-det-fri-filmer.png"></p>
 586
 587 <p>I expect the relative distribution of the remaining 3000 movies to
 588 be similar.</p>
 589
 590 <p>If you want to help, and want to ensure Wikipedia can be used to
 591 cross reference The Internet Archive and The Internet Movie Database,
 592 please make sure entries like this are listed under the "External
 593 links" heading on the Wikipedia article for the movie:</p>
 594
 595 <p><pre>
 596 * {{Internet Archive film|id=FightingLady}}
 597 * {{IMDb title|id=0036823|title=The Fighting Lady}}
 598 </pre></p>
 599
 600 <p>Please verify the links on the final page, to make sure you did not
 601 introduce a typo.</p>

 794       <div class="body"><p>I find it fascinating how many of the people being locked inside
 795 the proposed border wall between USA and Mexico support the idea.  The
 796 proposal to keep Mexicans out reminds me of
 797 <a href="http://www.history.com/news/10-things-you-may-not-know-about-the-berlin-wall">the
 798 propaganda twist from the East Germany government</a> calling the wall
 799 the “Antifascist Bulwark” after erecting the Berlin Wall, claiming
 800 that the wall was erected to keep enemies from creeping into East
 801 Germany, while it was obvious to the people locked inside it that it
 802 was erected to keep the people from escaping.</p>
 803
 804 <p>Do the people in USA supporting this wall really believe it is a
 805 one way wall, only keeping people on the outside from getting in,
 806 while not keeping people in the inside from getting out?</p>

 824       <div class="date"> 9th October 2017</div>
 825       <div class="body"><p>At my nearby maker space,
 826 <a href="http://sonen.ifi.uio.no/">Sonen</a>, I heard the story that it
 827 was easier to generate gcode files for theyr 3D printers (Ultimake 2+)
 828 on Windows and MacOS X than Linux, because the software involved had
 829 to be manually compiled and set up on Linux while premade packages
 830 worked out of the box on Windows and MacOS X.  I found this annoying,
 831 as the software involved,
 832 <a href="https://github.com/Ultimaker/Cura">Cura</a>, is free software
 833 and should be trivial to get up and running on Linux if someone took
 834 the time to package it for the relevant distributions.  I even found
 835 <a href="https://bugs.debian.org/706656">a request for adding into
 836 Debian</a> from 2013, which had seem some activity over the years but
 837 never resulted in the software showing up in Debian.  So a few days
 838 ago I offered my help to try to improve the situation.</p>
 839
 840 <p>Now I am very happy to see that all the packages required by a
 841 working Cura in Debian are uploaded into Debian and waiting in the NEW
 842 queue for the ftpmasters to have a look.  You can track the progress
 843 on
 844 <a href="https://qa.debian.org/developer.php?email=3dprinter-general%40lists.alioth.debian.org">the
 845 status page for the 3D printer team</a>.</p>
 846
 847 <p>The uploaded packages are a bit behind upstream, and was uploaded
 848 now to get slots in <a href="https://ftp-master.debian.org/new.html">the NEW
 849 queue</a> while we work up updating the packages to the latest
 850 upstream version.</p>
 851
 852 <p>On a related note, two competitors for Cura, which I found harder
 853 to use and was unable to configure correctly for Ultimaker 2+ in the
 854 short time I spent on it, are already in Debian.  If you are looking
 855 for 3D printer "slicers" and want something already available in
 856 Debian, check out
 857 <a href="https://tracker.debian.org/pkg/slic3r">slic3r</a> and
 858 <a href="https://tracker.debian.org/pkg/slic3r-prusa">slic3r-prusa</a>.
 859 The latter is a fork of the former.</p>

 878       <div class="body">Når jeg holder på med ulike prosjekter, så trenger jeg stadig ulike
 879 skruer.  Det siste prosjektet jeg holder på med er å lage
 880 <a href="https://www.thingiverse.com/thing:676916">en boks til en
 881 HDMI-touch-skjerm</a> som skal brukes med Raspberry Pi.  Boksen settes
 882 sammen med skruer og bolter, og jeg har vært i tvil om hvor jeg kan
 883 få tak i de riktige skruene.  Clas Ohlson og Jernia i nærheten har
 884 sjelden hatt det jeg trenger.  Men her om dagen fikk jeg et fantastisk
 885 tips for oss som bor i Oslo.
 886 <a href="http://www.zachskruer.no/">Zachariassen Jernvare AS</a> i
 887 <a href="http://www.openstreetmap.org/?mlat=59.93421&mlon=10.76795#map=19/59.93421/10.76795">Hegermannsgate
 888 23A på Torshov</a> har et fantastisk utvalg, og åpent mellom 09:00 og
 889 17:00.  De selger skruer, muttere, bolter, skiver etc i løs vekt, og
 890 så langt har jeg fått alt jeg har lett etter.  De har i tillegg det
 891 meste av annen jernvare, som verktøy, lamper, ledninger, etc.  Jeg
 892 håper de har nok kunder til å holde det gående lenge, da dette er en
 893 butikk jeg kommer til å besøke ofte.  Butikken er et funn å ha i
 894 nabolaget for oss som liker å bygge litt selv. :)</p>
