14 <description>&lt;p&gt;I &lt;a href=&quot;https://no.wikipedia.org/wiki/VHS&quot;&gt;VHS-kassettenes&lt;/a&gt;
15 tid var det rett frem å ta vare på et TV-program en ønsket å kunne se
16 senere, uten å være avhengig av at programmet ble sendt på nytt.
17 Kanskje ønsket en å se programmet på hytten der det ikke var
18 TV-signal, eller av andre grunner ha det tilgjengelig for fremtidig
19 fornøyelse. Dette er blitt vanskeligere med introduksjon av
20 digital-TV og webstreaming, der opptak til harddisk er utenfor de
21 flestes kontroll. Men for NRK her i Norge, finnes det heldigvis flere
22 fri programvare-alternativer, som jeg har
23 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Hvordan_enkelt_laste_ned_filmer_fra_NRK.html&quot;&gt;skrevet&lt;/a&gt;
24 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Hvordan_enkelt_laste_ned_filmer_fra_NRK_med_den__nye__l_sningen.html&quot;&gt;om&lt;/a&gt;
25 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Nedlasting_fra_NRK__som_Matroska_med_undertekster.html&quot;&gt;før&lt;/a&gt;.
26 Så lenge kilden for nedlastingen er lovlig lagt ut på nett (hvilket
27 jeg antar NRK gjør), så er slik lagring til privat bruk også lovlig i
28 Norge.&lt;/p&gt;
29
30 &lt;p&gt;Sist jeg så på saken, i 2016, nevnte jeg at
31 &lt;a href=&quot;https://rg3.github.com/youtube-dl/&quot;&gt;youtube-dl&lt;/a&gt; ikke kunne
32 bake undertekster fra NRK inn i videofilene, og at jeg derfor
33 foretrakk andre alternativer. Nylig oppdaget jeg at dette har endret
34 seg. Fordelen med youtube-dl er at den er tilgjengelig direkte fra
35 Linux-distribusjoner som &lt;a href=&quot;https://www.debian.org/&quot;&gt;Debian&lt;/a&gt;
36 og &lt;a href=&quot;https://www.ubuntu.com/&quot;&gt;Ubuntu&lt;/a&gt;, slik at en slipper å
37 finne ut selv hvordan en skal få dem til å virke.&lt;/p&gt;
38
39 &lt;p&gt;For å laste ned et NRK-innslag med undertekster, og få den norske
40 underteksten pakket inn i videofilen, så kan følgende kommando
41 brukes:&lt;/p&gt;
42
43 &lt;p&gt;&lt;pre&gt;
44 youtube-dl --write-sub --sub-format ttml \
45 --convert-subtitles srt --embed-subs \
46 https://tv.nrk.no/serie/ramm-ferdig-gaa/MUHU11000316/27-04-2018
47 &lt;/pre&gt;&lt;/p&gt;
48
49 &lt;p&gt;URL-eksemplet er dagens toppsak på tv.nrk.no. Resultatet er en
50 MP4-fil med filmen og undertekster som kan spilles av med VLC. Merk
51 at VLC ikke viser frem undertekster før du aktiverer dem. For å gjøre
52 det, høyreklikk med musa i fremviservinduet, velg menyvalget for
53 undertekst og så norsk språk. Jeg testet også &#39;--write-auto-sub&#39;,
54 men det kommandolinjeargumentet ser ikke ut til å fungere, så jeg
55 endte opp med settet med argumentlisten over, som jeg fant i en
56 feilrapport i youtube-dl-prosjektets samling over feilrapporter.&lt;/p&gt;
57
58 &lt;p&gt;Denne støtten i youtube-dl gjør det svært enkelt å lagre
59 NRK-innslag, det være seg nyheter, filmer, serier eller dokumentater,
60 for å ha dem tilgjengelig for fremtidig referanse og bruk, uavhengig
61 av hvor lenge innslagene ligger tilgjengelig hos NRK.&lt;/p&gt;
62
63 &lt;p&gt;Programmet youtube-dl støtter også en rekke andre nettsteder, se
64 prosjektoversikten for
65 &lt;a href=&quot;http://rg3.github.io/youtube-dl/supportedsites.html&quot;&gt;en

79 melder i dag at flertallet i Familie- og kulturkomiteen på Stortinget
80 har bestemt seg for å introdusere en ny sensurinfrastruktur i Norge.
81 Fra før har Norge en «frivillig» sensurinfrastruktur basert på
82 DNS-navn, der de største ISP-ene basert på en liste med DNS-navn
83 forgifter DNS-svar og omdirigerer til et annet IP-nummer enn det som
84 ligger i DNS. Nå kommer altså IP-basert omdirigering i tillegg. Når
85 infrastrukturen er på plass, er sensur av IP-adresser redusert et
86 spørsmål om hvilke IP-nummer som skal blokkeres. Listen over
87 IP-adresser vil naturligvis endre seg etter hvert som myndighetene
88 endrer seg. Det er ingen betryggende tanke.&lt;/p&gt;

93 <title>En grunn til å takke nei til usikker digital post</title>

96 <pubDate>Mon, 2 Apr 2018 13:30:00 +0200</pubDate>
97 <description>&lt;p&gt;Brevpost er beskyttet av straffelovens bestemmelse som gjør det
98 kriminelt å åpne andres brev. Dette følger av (ny) straffelovs
99 &lt;a href=&quot;https://lovdata.no/dokument/NL/lov/2005-05-20-28205&quot;&gt;§ 205
100 (Krenkelse av retten til privat kommunikasjon)&lt;/a&gt;, som sier at «Med
101 bot eller fengsel inntil 2 år straffes den som uberettiget ... c)
102 åpner brev eller annen lukket skriftlig meddelelse som er adressert
103 til en annen, eller på annen måte skaffer seg uberettiget tilgang til
104 innholdet.» Dette gjelder såvel postbud som alle andre som har
105 befatning med brevet etter at avsender har befatning med et lukket
106 brev. Tilsvarende står også tidligere utgaver av den norske
107 straffeloven.&lt;/p&gt;
108
109 &lt;p&gt;Når en registrerer seg på usikre digitale postkasseløsningene, som
110 f.eks. Digipost og e-Boks, og slik tar disse i bruk, så gir en de som
111 står bak løsningene tillatelse til å åpne sine brev. Dette er
112 nødvendig for at innholdet i digital post skal kunne vises frem til
113 mottaker via tjenestens websider. Dermed gjelder ikke straffelovens
114 paragraf om forbud mot å åpne brev, da tilgangen ikke lenger er
115 uberettiget. En gir altså fremmede tilgang til å lese sin
116 korrespondanse. I tillegg vil bruk av slike usikre digitale
117 postbokser føre til at det blir registrert når du leser brevene, hvor
118 du befinner deg (vha. tilkoblingens IP-adresse), hvilket utstyr du
119 bruker og en rekke annen personlig informasjon som ikke er
120 tilgjengelig når papirpost brukes. Jeg foretrekker at det er
121 lovmessig beskyttelse av min korrespondanse, som jo inneholder privat
122 og personlig informasjon. Det bidrar til litt bedre vern av personlig
123 integritet i dagens norske samfunn.&lt;/p&gt;

130 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Self_appointed_leaders_of_the_Free_World.html</guid>
131 <pubDate>Thu, 22 Mar 2018 11:00:00 +0100</pubDate>
132 <description>&lt;p&gt;The leaders of the worlds have started to congratulate the
133 re-elected Russian head of state, and this causes some criticism. I
134 am though a little fascinated by a comment from USA senator John McCain,
135 &lt;a href=&quot;http://thehill.com/homenews/senate/379339-mccain-rips-trumps-congratulatory-call-to-putin-as-insult-to-russian-people&quot;&gt;sited
136 by The Hill and others&lt;/a&gt;:
137
138 &lt;p&gt;&lt;blockquote&gt;
139 &lt;p&gt;&quot;An American president does not lead the Free World by
140 congratulating dictators on winning sham elections.&quot;&lt;/p&gt;
141 &lt;/blockquote&gt;&lt;/p&gt;
142
143 &lt;p&gt;While I totally agree with the senator here, the way the quote is
144 phrased make me suspect that he is unaware of the simple fact that USA
145 have not lead the Free World since at least before its government
146 &lt;a href=&quot;https://en.wikipedia.org/wiki/Maher_Arar&quot;&gt;kidnapped a
147 completely innocent Canadian citizen in transit on his way home to
148 Canada via John F. Kennedy International Airport in September 2002 and
149 sent him to be tortured in Syria for a year&lt;/a&gt;.&lt;/p&gt;
150
151 &lt;p&gt;USA might be running ahead, but the path they are taking is not the
152 one taken by any Free World.&lt;/p&gt;

157 <title>Facebooks ability to sell your personal information is the real Cambridge Analytica scandal</title>
158 <link>http://people.skolelinux.org/pere/blog/Facebooks_ability_to_sell_your_personal_information_is_the_real_Cambridge_Analytica_scandal.html</link>
159 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Facebooks_ability_to_sell_your_personal_information_is_the_real_Cambridge_Analytica_scandal.html</guid>
160 <pubDate>Wed, 21 Mar 2018 16:30:00 +0100</pubDate>
161 <description>&lt;p&gt;So, Cambridge Analytica is getting some well deserved criticism for
162 (mis)using information it got from Facebook about 50 million people,
163 mostly in the USA. What I find a bit surprising, is how little
164 criticism Facebook is getting for handing the information over to
165 Cambridge Analytica and others in the first place. And what about the
166 people handing their private and personal information to Facebook?
167 And last, but not least, what about the government offices who are
168 handing information about the visitors of their web pages to Facebook?
169 No-one who looked at the terms of use of Facebook should be surprised
170 that information about peoples interests, political views, personal
171 lifes and whereabouts would be sold by Facebook.&lt;/p&gt;
172
173 &lt;p&gt;What I find to be the real scandal is the fact that Facebook is
174 selling your personal information, not that one of the buyers used it
175 in a way Facebook did not approve when exposed. It is well known that
176 Facebook is selling out their users privacy, but a scandal
177 nevertheless. Of course the information provided to them by Facebook
178 would be misused by one of the parties given access to personal
179 information about the millions of Facebook users. Collected
180 information will be misused sooner or later. The only way to avoid
181 such misuse, is to not collect the information in the first place. If
182 you do not want Facebook to hand out information about yourself for
183 the use and misuse of its customers, do not give Facebook the
184 information.&lt;/p&gt;
185
186 &lt;p&gt;Personally, I would recommend to completely remove your Facebook
187 account, and take back some control of your personal information.
188 &lt;a href=&quot;https://www.theguardian.com/technology/2018/mar/19/how-to-protect-your-facebook-privacy-or-delete-yourself-completely&quot;&gt;According
189 to The Guardian&lt;/a&gt;, it is a bit hard to find out how to request
190 account removal (and not just &#39;disabling&#39;). You need to
191 &lt;a href=&quot;https://www.facebook.com/help/224562897555674?helpref=faq_content&quot;&gt;visit
192 a specific Facebook page&lt;/a&gt; and click on &#39;let us know&#39; on that page
193 to get to &lt;a href=&quot;https://www.facebook.com/help/delete_account&quot;&gt;the
194 real account deletion screen&lt;/a&gt;. Perhaps something to consider? I
195 would not trust the information to really be deleted (who knows,
196 perhaps NSA, GCHQ and FRA already got a copy), but it might reduce the
197 exposure a bit.&lt;/p&gt;
198
199 &lt;p&gt;If you want to learn more about the capabilities of Cambridge
200 Analytica, I recommend to see the video recording of the one hour talk
201 Paul-Olivier Dehaye gave to &lt;a href=&quot;&quot;&gt;NUUG&lt;/a&gt; last april about
202 &lt;a href=&quot;https://www.nuug.no/aktiviteter/20170404-big-data-psychometric/&quot;&gt;
203 Data collection, psychometric profiling and their impact on
204 politics&lt;/a&gt;.&lt;/p&gt;
205
206 &lt;p&gt;And if you want to communicate with your friends and loved ones,
207 use some end-to-end encrypted method like
208 &lt;a href=&quot;https://www.signal.org/&quot;&gt;Signal&lt;/a&gt; or
209 &lt;a href=&quot;https://ring.cx/&quot;&gt;Ring&lt;/a&gt;, and stop sharing your private
210 messages with strangers like Facebook and Google.&lt;/p&gt;

219 <description>&lt;p&gt;I går kom det nok et argument for å holde seg unna det norske
220 helsevesenet. Da annonserte et stortingsflertall, bestående av Høyre,
221 Arbeiderpartiet, Fremskrittspartiet og Venstre, at de går inn for å
222 samle inn og lagre DNA-prøver fra hele befolkningen i Norge til evig
223 tid. Endringen gjelder innsamlede blodprøver fra nyfødte i Norge.
224 Det vil dermed ta litt tid før en har hele befolkningen, men det er
225 dit vi havner gitt nok tid. I dag er det nesten hundre prosent
226 oppslutning om undersøkelsen som gjøres like etter fødselen, på
227 bakgrunn av blodprøven det er snakk om å lagre, for å oppdage endel
228 medfødte sykdommer. Blodprøven lagres i dag i inntil seks år.
229 &lt;a href=&quot;https://www.stortinget.no/no/Saker-og-publikasjoner/Publikasjoner/Innstillinger/Stortinget/2017-2018/inns-201718-182l/?all=true&quot;&gt;Stortingets
230 flertallsinnstilling&lt;/a&gt; er at tidsbegrensingen skal fjernes, og mener
231 at tidsubegrenset lagring ikke vil påvirke oppslutningen om
232 undersøkelsen.&lt;/p&gt;
233
234 &lt;p&gt;Datatilsynet har ikke akkurat applaudert forslaget:&lt;/p&gt;
235
236 &lt;p&gt;&lt;blockquote&gt;
237
238 &lt;p&gt;«Datatilsynet mener forslaget ikke i tilstrekkelig grad
239 synliggjør hvilke etiske og personvernmessige utfordringer som må
240 diskuteres før en etablerer en nasjonal biobank med blodprøver fra
241 hele befolkningen.»&lt;/p&gt;
242
243 &lt;/blockquote&gt;&lt;/p&gt;
244
245 &lt;p&gt;Det er flere historier om hvordan innsamlet biologisk materiale har
246 blitt brukt til andre formål enn de ble innsamlet til, og historien om
247 &lt;a href=&quot;https://www.aftenposten.no/norge/i/Ql0WR/Na-ma-Folkehelsa-slette-uskyldiges-DNA-info&quot;&gt;folkehelseinstituttets
248 lagring på vegne av politiet (Kripos) av innsamlet biologisk materiale
249 og DNA-informasjon i strid med loven&lt;/a&gt; viser at en ikke kan være
250 trygg på at lover og intensjoner beskytter de som blir berørt mot
251 misbruk av slik privat og personlig informasjon.&lt;/p&gt;
252
253 &lt;p&gt;Det er verdt å merke seg at det kan forskes på de innsamlede
254 blodprøvene uten samtykke fra den det gjelder (eller foreldre når det
255 gjelder barn), etter en lovendring for en stund tilbake, med mindre
256 det er sendt inn skjema der en reserverer seg mot forskning uten
257 samtykke. Skjemaet er tilgjengelig fra
258 &lt;a href=&quot;https://www.fhi.no/arkiv/publikasjoner/for-pasienter-skjema-for-reservasjo/&quot;&gt;folkehelseinstituttets
259 websider&lt;/a&gt;, og jeg anbefaler, uavhengig av denne saken, varmt alle å
260 sende inn skjemaet for å dokumentere hvor mange som ikke synes det er
261 greit å fjerne krav om samtykke.&lt;/p&gt;
262
263 &lt;p&gt;I tillegg bør en kreve destruering av alt biologisk materiale som
264 er samlet inn om en selv, for å redusere eventuelle negative
265 konsekvenser i fremtiden når materialet kommer på avveie eller blir
266 brukt uten samtykke, men det er så vidt jeg vet ikke noe system for
267 dette i dag.&lt;/p&gt;
268
269 &lt;p&gt;Som vanlig, hvis du bruker Bitcoin og ønsker å vise din støtte til
270 det jeg driver med, setter jeg pris på om du sender Bitcoin-donasjoner
271 til min adresse

277 <title>First rough draft Norwegian and Spanish edition of the book Made with Creative Commons</title>
278 <link>http://people.skolelinux.org/pere/blog/First_rough_draft_Norwegian_and_Spanish_edition_of_the_book_Made_with_Creative_Commons.html</link>

280 <pubDate>Tue, 13 Mar 2018 13:00:00 +0100</pubDate>
281 <description>&lt;p&gt;I am working on publishing yet another book related to Creative
282 Commons. This time it is a book filled with interviews and histories
283 from those around the globe making a living using Creative
284 Commons.&lt;/p&gt;
285
286 &lt;p&gt;Yesterday, after many months of hard work by several volunteer
287 translators, the first draft of a Norwegian Bokmål edition of the book
288 &lt;a href=&quot;https://madewith.cc&quot;&gt;Made with Creative Commons from 2017&lt;/a&gt;
289 was complete. The Spanish translation is also complete, while the
290 Dutch, Polish, German and Ukraine edition need a lot of work. Get in
291 touch if you want to help make those happen, or would like to
292 translate into your mother tongue.&lt;/p&gt;
293
294 &lt;p&gt;The whole book project started when
295 &lt;a href=&quot;http://gwolf.org/node/4102&quot;&gt;Gunnar Wolf announced&lt;/a&gt; that he
296 was going to make a Spanish edition of the book. I noticed, and
297 offered some input on how to make a book, based on my experience with
298 translating the
299 &lt;a href=&quot;https://www.lulu.com/shop/lawrence-lessig/fri-kultur/paperback/product-22441576.html&quot;&gt;Free
300 Culture&lt;/a&gt; and
301 &lt;a href=&quot;https://debian-handbook.info/get/#norwegian&quot;&gt;The Debian
302 Administrator&#39;s Handbook&lt;/a&gt; books to Norwegian Bokmål. To make a
303 long story short, we ended up working on a Bokmål edition, and now the
304 first rough translation is complete, thanks to the hard work of
305 Ole-Erik Yrvin, Ingrid Yrvin, Allan Nordhøy and myself. The first
306 proof reading is almost done, and only the second and third proof
307 reading remains. We will also need to translate the 14 figures and
308 create a book cover. Once it is done we will publish the book on
309 paper, as well as in PDF, ePub and possibly Mobi formats.&lt;/p&gt;
310
311 &lt;p&gt;The book itself originates as a manuscript on Google Docs, is
312 downloaded as ODT from there and converted to Markdown using pandoc.
313 The Markdown is modified by a script before is converted to DocBook
314 using pandoc. The DocBook is modified again using a script before it
315 is used to create a Gettext POT file for translators. The translated
316 PO file is then combined with the earlier mentioned DocBook file to
317 create a translated DocBook file, which finally is given to dblatex to
318 create the final PDF. The end result is a set of editions of the
319 manuscript, one English and one for each of the translations.&lt;/p&gt;
320
321 &lt;p&gt;The translation is conducted using
322 &lt;a href=&quot;https://hosted.weblate.org/projects/madewithcc/translation/&quot;&gt;the
323 Weblate web based translation system&lt;/a&gt;. Please have a look there
324 and get in touch if you would like to help out with proof
325 reading. :)&lt;/p&gt;
326
327 &lt;p&gt;As usual, if you use Bitcoin and want to show your support of my
328 activities, please send Bitcoin donations to my address

338 <description>&lt;p&gt;Today I was pleasantly surprised to discover my operating system of
339 choice, Debian, was used in the info screens on the subway stations.
340 While passing Nydalen subway station in Oslo, Norway, I discovered the
341 info screen booting with some text scrolling. I was not quick enough
342 with my camera to be able to record a video of the scrolling boot
343 screen, but I did get a photo from when the boot got stuck with a
344 corrupt file system:

346 &lt;p align=&quot;center&quot;&gt;&lt;a href=&quot;http://people.skolelinux.org/pere/blog/images/2018-03-02-ruter-debian-lenny.jpeg&quot;&gt;&lt;img align=&quot;center&quot; width=&quot;40%&quot; src=&quot;http://people.skolelinux.org/pere/blog/images/2018-03-02-ruter-debian-lenny.jpeg&quot; alt=&quot;[photo of subway info screen]&quot;&gt;&lt;/a&gt;&lt;/p&gt;
347
348 &lt;p&gt;While I am happy to see Debian used more places, some details of the
349 content on the screen worries me.&lt;/p&gt;
350
351 &lt;p&gt;The image show the version booting is &#39;Debian GNU/Linux lenny/sid&#39;,
352 indicating that this is based on code taken from Debian Unstable/Sid
353 after Debian Etch (version 4) was released 2007-04-08 and before
354 Debian Lenny (version 5) was released 2009-02-14. Since Lenny Debian
355 has released version 6 (Squeeze) 2011-02-06, 7 (Wheezy) 2013-05-04, 8
356 (Jessie) 2015-04-25 and 9 (Stretch) 2017-06-15, according to
357 &lt;a href=&quot;https://en.wikipedia.org/wiki/Debian_version_history&quot;&gt;a Debian
358 version history on Wikpedia&lt;/a&gt;. This mean the system is running
359 around 10 year old code, with no security fixes from the vendor for
360 many years.&lt;/p&gt;
361
362 &lt;p&gt;This is not the first time I discover the Oslo subway company,
363 Ruter, running outdated software. In 2012,
364 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Er_billettautomatene_til_kollektivtrafikken_i_Oslo_uten_sikkerhetsoppdateringer_.html&quot;&gt;I
365 discovered the ticket vending machines were running Windows 2000&lt;/a&gt;,
366 and this was
367 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Fortsatt_ingen_sikkerhetsoppdateringer_for_billettautomatene_til_kollektivtrafikken_i_Oslo_.html&quot;&gt;still
368 the case in 2016&lt;/a&gt;. Given the response from the responsible people
369 in 2016, I would assume the machines are still running unpatched
370 Windows 2000. Thus, an unpatched Debian setup come as no surprise.&lt;/p&gt;

383 <title>The SysVinit upstream project just migrated to git</title>

387 <description>&lt;p&gt;Surprising as it might sound, there are still computers using the
388 traditional Sys V init system, and there probably will be until
389 systemd start working on Hurd and FreeBSD.
390 &lt;a href=&quot;https://savannah.nongnu.org/projects/sysvinit&quot;&gt;The upstream
391 project still exist&lt;/a&gt;, though, and up until today, the upstream
392 source was available from Savannah via subversion. I am happy to
393 report that this just changed.&lt;/p&gt;
394
395 &lt;p&gt;The upstream source is now in Git, and consist of three
396 repositories:&lt;/p&gt;
397
398 &lt;ul&gt;
399
400 &lt;li&gt;&lt;a href=&quot;http://git.savannah.nongnu.org/cgit/sysvinit.git&quot;&gt;sysvinit&lt;/a&gt;&lt;/li&gt;
401 &lt;li&gt;&lt;a href=&quot;http://git.savannah.nongnu.org/cgit/sysvinit/insserv.git&quot;&gt;insserv&lt;/a&gt;&lt;/li&gt;
402 &lt;li&gt;&lt;a href=&quot;http://git.savannah.nongnu.org/cgit/sysvinit/startpar.git&quot;&gt;startpar&lt;/a&gt;&lt;/li&gt;
403
404 &lt;/ul&gt;
405
406 &lt;p&gt;I do not really spend much time on the project these days, and I
407 has mostly retired, but found it best to migrate the source to a good
408 version control system to help those willing to move it forward.&lt;/p&gt;

417 <title>Using VLC to stream bittorrent sources</title>
418 <link>http://people.skolelinux.org/pere/blog/Using_VLC_to_stream_bittorrent_sources.html</link>
419 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Using_VLC_to_stream_bittorrent_sources.html</guid>
420 <pubDate>Wed, 14 Feb 2018 08:00:00 +0100</pubDate>
421 <description>&lt;p&gt;A few days ago, a new major version of
422 &lt;a href=&quot;https://www.videolan.org/&quot;&gt;VLC&lt;/a&gt; was announced, and I
423 decided to check out if it now supported streaming over
424 &lt;a href=&quot;http://bittorrent.org/&quot;&gt;bittorrent&lt;/a&gt; and
425 &lt;a href=&quot;https://webtorrent.io&quot;&gt;webtorrent&lt;/a&gt;. Bittorrent is one of
426 the most efficient ways to distribute large files on the Internet, and
427 Webtorrent is a variant of Bittorrent using
428 &lt;a href=&quot;https://webrtc.org&quot;&gt;WebRTC&lt;/a&gt; as its transport channel,
429 allowing web pages to stream and share files using the same technique.
430 The network protocols are similar but not identical, so a client
431 supporting one of them can not talk to a client supporting the other.
432 I was a bit surprised with what I discovered when I started to look.
433 Looking at
434 &lt;a href=&quot;https://www.videolan.org/vlc/releases/3.0.0.html&quot;&gt;the release
435 notes&lt;/a&gt; did not help answering this question, so I started searching
436 the web. I found several news articles from 2013, most of them
437 tracing the news from Torrentfreak
438 (&quot;&lt;a href=https://torrentfreak.com/open-source-giant-vlc-mulls-bittorrent-support-130211/&quot;&gt;Open
439 Source Giant VLC Mulls BitTorrent Streaming Support&lt;/a&gt;&quot;), about a
440 initiative to pay someone to create a VLC patch for bittorrent
441 support. To figure out what happend with this initiative, I headed
442 over to the #videolan IRC channel and asked if there were some bug or
443 feature request tickets tracking such feature. I got an answer from
444 lead developer Jean-Babtiste Kempf, telling me that there was a patch
445 but neither he nor anyone else knew where it was. So I searched a bit
446 more, and came across an independent
447 &lt;a href=&quot;https://github.com/johang/vlc-bittorrent&quot;&gt;VLC plugin to add
448 bittorrent support&lt;/a&gt;, created by Johan Gunnarsson in 2016/2017.
449 Again according to Jean-Babtiste, this is not the patch he was talking
450 about.&lt;/p&gt;
451
452 &lt;p&gt;Anyway, to test the plugin, I made a working Debian package from
453 the git repository, with some modifications. After installing this
454 package, I could stream videos from
455 &lt;a href=&quot;https://www.archive.org/&quot;&gt;The Internet Archive&lt;/a&gt; using VLC
456 commands like this:&lt;/p&gt;
457
458 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
459 vlc https://archive.org/download/LoveNest/LoveNest_archive.torrent
460 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
461
462 &lt;p&gt;The plugin is supposed to handle magnet links too, but since The
463 Internet Archive do not have magnet links and I did not want to spend
464 time tracking down another source, I have not tested it. It can take
465 quite a while before the video start playing without any indication of
466 what is going on from VLC. It took 10-20 seconds when I measured it.
467 Some times the plugin seem unable to find the correct video file to
468 play, and show the metadata XML file name in the VLC status line. I
469 have no idea why.&lt;/p&gt;
470
471 &lt;p&gt;I have created a &lt;a href=&quot;https://bugs.debian.org/890360&quot;&gt;request for
472 a new package in Debian (RFP)&lt;/a&gt; and
473 &lt;a href=&quot;https://github.com/johang/vlc-bittorrent/issues/1&quot;&gt;asked if
474 the upstream author is willing to help make this happen&lt;/a&gt;. Now we
475 wait to see what come out of this. I do not want to maintain a
476 package that is not maintained upstream, nor do I really have time to
477 maintain more packages myself, so I might leave it at this. But I
478 really hope someone step up to do the packaging, and hope upstream is
479 still maintaining the source. If you want to help, please update the
480 RFP request or the upstream issue.&lt;/p&gt;
481
482 &lt;p&gt;I have not found any traces of webtorrent support for VLC.&lt;/p&gt;
