  14                 <description>&lt;p&gt;Surprising as it might sound, there are still computers using the
  15 traditional Sys V init system, and there probably will be until
  16 systemd start working on Hurd and FreeBSD.
  17 &lt;a href=&quot;https://savannah.nongnu.org/projects/sysvinit&quot;&gt;The upstream
  18 project still exist&lt;/a&gt;, though, and up until today, the upstream
  19 source was available from Savannah via subversion.  I am happy to
  20 report that this just changed.&lt;/p&gt;
  21
  22 &lt;p&gt;The upstream source is now in Git, and consist of three
  23 repositories:&lt;/p&gt;
  24
  25 &lt;ul&gt;
  26
  27 &lt;li&gt;&lt;a href=&quot;http://git.savannah.nongnu.org/cgit/sysvinit.git&quot;&gt;sysvinit&lt;/a&gt;&lt;/li&gt;
  28 &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;
  29 &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;
  30
  31 &lt;/ul&gt;
  32
  33 &lt;p&gt;I do not really spend much time on the project these days, and I
  34 has mostly retired, but found it best to migrate the source to a good
  35 version control system to help those willing to move it forward.&lt;/p&gt;

  45                 <link>http://www.hungry.com/~pere/blog/Using_VLC_to_stream_bittorrent_sources.html</link>
  46                 <guid isPermaLink="true">http://www.hungry.com/~pere/blog/Using_VLC_to_stream_bittorrent_sources.html</guid>
  47                 <pubDate>Wed, 14 Feb 2018 08:00:00 +0100</pubDate>
  48                 <description>&lt;p&gt;A few days ago, a new major version of
  49 &lt;a href=&quot;https://www.videolan.org/&quot;&gt;VLC&lt;/a&gt; was announced, and I
  50 decided to check out if it now supported streaming over
  51 &lt;a href=&quot;http://bittorrent.org/&quot;&gt;bittorrent&lt;/a&gt; and
  52 &lt;a href=&quot;https://webtorrent.io&quot;&gt;webtorrent&lt;/a&gt;.  Bittorrent is one of
  53 the most efficient ways to distribute large files on the Internet, and
  54 Webtorrent is a variant of Bittorrent using
  55 &lt;a href=&quot;https://webrtc.org&quot;&gt;WebRTC&lt;/a&gt; as its transport channel,
  56 allowing web pages to stream and share files using the same technique.
  57 The network protocols are similar but not identical, so a client
  58 supporting one of them can not talk to a client supporting the other.
  59 I was a bit surprised with what I discovered when I started to look.
  60 Looking at
  61 &lt;a href=&quot;https://www.videolan.org/vlc/releases/3.0.0.html&quot;&gt;the release
  62 notes&lt;/a&gt; did not help answering this question, so I started searching
  63 the web.  I found several news articles from 2013, most of them
  64 tracing the news from Torrentfreak
  65 (&quot;&lt;a href=https://torrentfreak.com/open-source-giant-vlc-mulls-bittorrent-support-130211/&quot;&gt;Open
  66 Source Giant VLC Mulls BitTorrent Streaming Support&lt;/a&gt;&quot;), about a
  67 initiative to pay someone to create a VLC patch for bittorrent
  68 support.  To figure out what happend with this initiative, I headed
  69 over to the #videolan IRC channel and asked if there were some bug or
  70 feature request tickets tracking such feature.  I got an answer from
  71 lead developer Jean-Babtiste Kempf, telling me that there was a patch
  72 but neither he nor anyone else knew where it was.  So I searched a bit
  73 more, and came across an independent
  74 &lt;a href=&quot;https://github.com/johang/vlc-bittorrent&quot;&gt;VLC plugin to add
  75 bittorrent support&lt;/a&gt;, created by Johan Gunnarsson in 2016/2017.
  76 Again according to Jean-Babtiste, this is not the patch he was talking
  77 about.&lt;/p&gt;
  78
  79 &lt;p&gt;Anyway, to test the plugin, I made a working Debian package from
  80 the git repository, with some modifications.  After installing this
  81 package, I could stream videos from
  82 &lt;a href=&quot;https://www.archive.org/&quot;&gt;The Internet Archive&lt;/a&gt; using VLC
  83 commands like this:&lt;/p&gt;
  84
  85 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
  86 vlc https://archive.org/download/LoveNest/LoveNest_archive.torrent
  87 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
  88
  89 &lt;p&gt;The plugin is supposed to handle magnet links too, but since The
  90 Internet Archive do not have magnet links and I did not want to spend
  91 time tracking down another source, I have not tested it.  It can take
  92 quite a while before the video start playing without any indication of
  93 what is going on from VLC.  It took 10-20 seconds when I measured it.
  94 Some times the plugin seem unable to find the correct video file to
  95 play, and show the metadata XML file name in the VLC status line.  I
  96 have no idea why.&lt;/p&gt;
  97
  98 &lt;p&gt;I have created a &lt;a href=&quot;https://bugs.debian.org/890360&quot;&gt;request for
  99 a new package in Debian (RFP)&lt;/a&gt; and
 100 &lt;a href=&quot;https://github.com/johang/vlc-bittorrent/issues/1&quot;&gt;asked if
 101 the upstream author is willing to help make this happen&lt;/a&gt;.  Now we
 102 wait to see what come out of this.  I do not want to maintain a
 103 package that is not maintained upstream, nor do I really have time to
 104 maintain more packages myself, so I might leave it at this.  But I
 105 really hope someone step up to do the packaging, and hope upstream is
 106 still maintaining the source.  If you want to help, please update the
 107 RFP request or the upstream issue.&lt;/p&gt;
 108
 109 &lt;p&gt;I have not found any traces of webtorrent support for VLC.&lt;/p&gt;

 122                 <description>&lt;p&gt;A new version of the
 123 &lt;a href=&quot;https://tracker.debian.org/pkg/cura&quot;&gt;3D printer slicer
 124 software Cura&lt;/a&gt;, version 3.1.0, is now available in Debian Testing
 125 (aka Buster) and Debian Unstable (aka Sid).  I hope you find it
 126 useful.  It was uploaded the last few days, and the last update will
 127 enter testing tomorrow.  See the
 128 &lt;a href=&quot;https://ultimaker.com/en/products/cura-software/release-notes&quot;&gt;release
 129 notes&lt;/a&gt; for the list of bug fixes and new features.  Version 3.2
 130 was announced 6 days ago.  We will try to get it into Debian as
 131 well.&lt;/p&gt;
 132
 133 &lt;p&gt;More information related to 3D printing is available on the
 134 &lt;a href=&quot;https://wiki.debian.org/3DPrinting&quot;&gt;3D printing&lt;/a&gt; and

 149                 <description>&lt;p&gt;Jeg lar meg fascinere av en artikkel
 150 &lt;a href=&quot;https://www.dagbladet.no/kultur/terroristene-star-pa-dora/69436116&quot;&gt;i
 151 Dagbladet om Kinas håndtering av Xinjiang&lt;/a&gt;, spesielt følgende
 152 utsnitt:&lt;/p&gt;
 153
 154 &lt;p&gt;&lt;blockquote&gt;
 155
 156 &lt;p&gt;«I den sørvestlige byen Kashgar nærmere grensa til
 157 Sentral-Asia meldes det nå at 120.000 uigurer er internert i såkalte
 158 omskoleringsleirer. Samtidig er det innført et omfattende
 159 helsesjekk-program med innsamling og lagring av DNA-prøver fra
 160 absolutt alle innbyggerne. De mest avanserte overvåkingsmetodene
 161 testes ut her. Programmer for å gjenkjenne ansikter og stemmer er på
 162 plass i regionen. Der har de lokale myndighetene begynt å installere
 163 GPS-systemer i alle kjøretøy og egne sporingsapper i
 164 mobiltelefoner.&lt;/p&gt;
 165
 166 &lt;p&gt;Politimetodene griper så dypt inn i folks dagligliv at motstanden
 167 mot Beijing-regimet øker.»&lt;/p&gt;
 168
 169 &lt;/blockquote&gt;&lt;/p&gt;
 170
 171 &lt;p&gt;Beskrivelsen avviker jo desverre ikke så veldig mye fra tilstanden
 172 her i Norge.&lt;/p&gt;
 173
 174 &lt;table&gt;

 176 &lt;th&gt;Dataregistrering&lt;/th&gt;

 179
 180 &lt;tr&gt;
 181 &lt;td&gt;Innsamling og lagring av DNA-prøver fra befolkningen&lt;/td&gt;
 182 &lt;td&gt;Ja&lt;/td&gt;
 183 &lt;td&gt;Delvis, planlagt for alle nyfødte.&lt;/td&gt;
 184 &lt;/tr&gt;
 185
 186 &lt;tr&gt;
 187 &lt;td&gt;Ansiktsgjenkjenning&lt;/td&gt;
 188 &lt;td&gt;Ja&lt;/td&gt;
 189 &lt;td&gt;Ja&lt;/td&gt;
 190 &lt;/tr&gt;
 191
 192 &lt;tr&gt;
 193 &lt;td&gt;Stemmegjenkjenning&lt;/td&gt;
 194 &lt;td&gt;Ja&lt;/td&gt;
 195 &lt;td&gt;Nei&lt;/td&gt;
 196 &lt;/tr&gt;
 197
 198 &lt;tr&gt;
 199 &lt;td&gt;Posisjons-sporing av mobiltelefoner&lt;/td&gt;
 200 &lt;td&gt;Ja&lt;/td&gt;
 201 &lt;td&gt;Ja&lt;/td&gt;
 202 &lt;/tr&gt;
 203
 204 &lt;tr&gt;
 205 &lt;td&gt;Posisjons-sporing av biler&lt;/td&gt;
 206 &lt;td&gt;Ja&lt;/td&gt;
 207 &lt;td&gt;Ja&lt;/td&gt;
 208 &lt;/tr&gt;
 209
 210 &lt;/table&gt;
 211
 212 &lt;p&gt;I Norge har jo situasjonen rundt Folkehelseinstituttets lagring av
 213 DNA-informasjon på vegne av politiet, der de nektet å slette
 214 informasjon politiet ikke hadde lov til å ta vare på, gjort det klart
 215 at DNA tar vare på ganske lenge.  I tillegg finnes det utallige
 216 biobanker som lagres til evig tid, og det er planer om å innføre
 217 &lt;a href=&quot;https://www.aftenposten.no/norge/i/75E9/4-av-10-mener-staten-bor-lagre-DNA-profiler-pa-alle-nyfodte&quot;&gt;evig
 218 lagring av DNA-materiale fra alle spebarn som fødes&lt;/a&gt; (med mulighet
 219 for å be om sletting).&lt;/p&gt;
 220
 221 &lt;p&gt;I Norge er det system på plass for ansiktsgjenkjenning, som
 222 &lt;a href=&quot;https://www.nrk.no/norge/kun-gardermoen-har-teknologi-for-ansiktsgjenkjenning-i-norge-1.12719461&quot;&gt;en
 223 NRK-artikkel fra 2015&lt;/a&gt; forteller er aktiv på Gardermoen, samt
 224 &lt;a href=&quot;https://www.dagbladet.no/nyheter/inntil-27-000-bor-i-norge-under-falsk-id/60500781&quot;&gt;brukes
 225 til å analysere bilder innsamlet av myndighetene&lt;/a&gt;.  Brukes det også
 226 flere plasser?  Det er tett med overvåkningskamera kontrollert av
 227 politi og andre myndigheter i for eksempel Oslo sentrum.&lt;/p&gt;
 228
 229 &lt;p&gt;Jeg er ikke kjent med at Norge har noe system for identifisering av
 230 personer ved hjelp av stemmegjenkjenning.&lt;/p&gt;
 231
 232 &lt;p&gt;Posisjons-sporing av mobiltelefoner er ruinemessig tilgjengelig for
 233 blant annet politi, NAV og Finanstilsynet, i tråd med krav i
 234 telefonselskapenes konsesjon.  I tillegg rapporterer smarttelefoner
 235 sin posisjon til utviklerne av utallige mobil-apper, der myndigheter
 236 og andre kan hente ut informasjon ved behov.  Det er intet behov for
 237 noen egen app for dette.&lt;/p&gt;
 238
 239 &lt;p&gt;Posisjons-sporing av biler er rutinemessig tilgjengelig via et tett
 240 nett av målepunkter på veiene (automatiske bomstasjoner,
 241 køfribrikke-registrering, automatiske fartsmålere og andre veikamera).
 242 Det er i tillegg vedtatt at alle nye biler skal selges med utstyr for
 243 GPS-sporing (eCall).&lt;/p&gt;
 244
 245 &lt;p&gt;Det er jammen godt vi lever i et liberalt demokrati, og ikke en
 246 overvåkningsstat, eller?&lt;/p&gt;
 247

 262 &lt;p&gt;We write 2018, and it is 30 years since Unicode was introduced.
 263 Most of us in Norway have come to expect the use of our alphabet to
 264 just work with any computer system.  But it is apparently beyond reach
 265 of the computers printing recites at a restaurant.  Recently I visited
 266 a Peppes pizza resturant, and noticed a few details on the recite.
 267 Notice how &#39;ø&#39; and &#39;å&#39; are replaced with strange symbols in
 268 &#39;Servitør&#39;, &#39;Å BETALE&#39;, &#39;Beløp pr. gjest&#39;, &#39;Takk for besøket.&#39; and &#39;Vi

 271 &lt;p&gt;I would say that this state is passed sad and over in embarrassing.&lt;/p&gt;
