  25       <div class="body"><p>A fun way to learn how to program
  26 <a href="https://www.python.org/">Python</a> is to follow the
  27 instructions in the book
  28 "<a href="https://nostarch.com/programwithminecraft">Learn to program
  29 with Minecraft</a>", which introduces programming in Python to people
  30 who like to play with Minecraft.  The book uses a Python library to
  31 talk to a TCP/IP socket with an API accepting build instructions and
  32 providing information about the current players in a Minecraft world.
  33 The TCP/IP API was first created for the Minecraft implementation for
  34 Raspberry Pi, and has since been ported to some server versions of
  35 Minecraft.  The book contain recipes for those using Windows, MacOSX
  36 and Raspian.  But a little known fact is that you can follow the same
  37 recipes using the free software construction game
  38 <a href="https://minetest.org/">Minetest</a>.</p>
  39
  40 <p>There is <a href="https://github.com/sprintingkiwi/pycraft_mod">a
  41 Minetest module implementing the same API</a>, making it possible to
  42 use the Python programs coded to talk to Minecraft with Minetest too.
  43 I
  44 <a href="https://ftp-master.debian.org/new/minetest-mod-pycraft_0.20%2Bgit20180331.0376a0a%2Bdfsg-1.html">uploaded
  45 this module</a> to Debian two weeks ago, and as soon as it clears the
  46 FTP masters NEW queue, learning to program Python with Minetest on
  47 Debian will be a simple 'apt install' away.  The Debian package is
  48 maintained as part of the Debian Games team, and
  49 <a href="https://salsa.debian.org/games-team/unfinished/minetest-mod-pycraft">the
  50 packaging rules</a> are currently located under 'unfinished' on
  51 Salsa.</p>
  52
  53 <p>You will most likely need to install several of the Minetest
  54 modules in Debian for the examples included with the library to work
  55 well, as there are several blocks used by the example scripts that are
  56 provided via modules in Minetest.  Without the required blocks, a
  57 simple stone block is used instead.  My initial testing with a analog
  58 clock did not get gold arms as instructed in the python library, but
  59 instead used stone arms.</p>
  60
  61 <p>I tried to find a way to add the API to the desktop version of
  62 Minecraft, but were unable to find any working recipes.  The
  63 <a href="https://www.epiphanydigest.com/tag/minecraft-python-api/">recipes</a>
  64 I <a href="https://github.com/kbsriram/mcpiapi">found</a> are only
  65 working with a standalone Minecraft server setup.  Are there any
  66 options to use with the normal desktop version?</p>

  85       <div class="body"><p>A few hours ago, a new and improved version (2.4) of
  86 <a href="https://tracker.debian.org/pkg/vlc-plugin-bittorrent">the VLC
  87 bittorrent plugin</a> was uploaded to Debian.  This new version
  88 include a complete rewrite of the bittorrent related code, which seem
  89 to make the plugin non-blocking.  This mean you can actually exit VLC
  90 even when the plugin seem to be unable to get the bittorrent streaming
  91 started.  The new version also include support for filtering playlist
  92 by file extension using command line options, if you want to avoid
  93 processing audio, video or images.  The package is currently in Debian
  94 unstable, but should be available in Debian testing in two days.  To
  95 test it, simply install it like this:</p>
  96
  97 <p><pre>
  98 apt install vlc-plugin-bittorrent
  99 </pre></p>
 100
 101 <p>After it is installed, you can try to use it to play a file
 102 downloaded live via bittorrent like this:

 125       <div class="body"><p><a href="https://www.fn.no/Om-FN/Avtaler/Menneskerettigheter/FNs-verdenserklaering-om-menneskerettigheter">FNs
 126 menneskerettighetserklæring</a> artikkel 13 første punkt lyder som
 127 følger:</p>
 128
 129 <p><blockquote>
 130 Enhver har rett til å bevege seg fritt og til fritt å velge
 131 oppholdssted innenfor en stats grenser.
 132 </blockquote></p>
 133
 134 <p>Det er altså en menneskerett å kunne bevege seg fritt i landet.
 135 For å bevege seg fritt i landet, så må en kunne bevege seg uten å bli
 136 sporet.  Det vil i dagens samfunn innebære å bevege seg uten å legge
 137 igjen digitale spor og uten å være radiomerket.  Hvis en vet at ens
 138 bevegelser, hvor en befinner seg når, og hvem som befinner seg i
 139 nærheten, blir samlet inn og gjort tilgjengelig for fremmede, det være
 140 seg myndighetene eller private organisasjoner, så kan en ikke lenger
 141 bevege seg fritt.  Dette gjør at det er en forutsetning for å ha glede
 142 av retten til å bevege seg fritt i landet at en motstår fristelsen til
 143 å legge igjen digitale spor når en betaler for seg.  Rettigheter som
 144 ikke blir brukt, blir fjernet.  Den eneste måten i dag å unngå å legge
 145 igjen digitale spor når en betaler for seg, er å betale med kontanter,
 146 samt takke nei til å legge igjen navn og adresse (slik f.eks. Elkjøp
 147 ber om &mdash; jeg sier de kan legge inn «anonym anonym» når
 148 datasystemet deres trenger et navn).  Personlig anbefaler jeg å
 149 konsekvent bruke kontant betaling når man beveger seg rundt, for å
 150 bidra til forsvaret av menneskerettighetene i Norge.  Kanskje noe også
 151 for deg?  Merk at det ikke er tilstrekkelig for å unngå sporing å
 152 betale med kontanter, men det er et lite steg i riktig retning.</p>
 153
 154 <p>Det er flere andre argumenter i tillegg til
 155 menneskerettighetsargumentet for å bruke kontanter.  I går hadde
 156 Dagbladet en utmerket kommentar av sin journalist John Olav Egeland om
 157 hvilket
 158 <a href="https://www.dagbladet.no/kultur/kontantlost-diktatur/70543434">kontantløst
 159 diktatur</a> som venter oss hvis mange nok slutter å insistere på å
 160 betale med kontanter.  Jeg anbefaler deg å lese den.</p>

 181       <div class="body"><p>Yesterday, I had the pleasure of watching on Frikanalen the OWASP
 182 talk by Scott Helme titled
 183 "<a href="https://frikanalen.no/video/626080/">What We’ve Learned From
 184 Billions of Security Reports</a>".  I had not heard of the
 185 <a href="https://en.wikipedia.org/wiki/Content_Security_Policy">Content
 186 Security Policy standard</a> nor its ability to "call home" when a
 187 browser detect a policy breach (I do not follow web page design
 188 development much these days), and found the talk very illuminating.</p>
 189
 190 <p>The mechanism allow a web site owner to use HTTP headers to tell
 191 visitors web browser which sources (internal and external) are allowed to
 192 be used on the web site.  Thus it become possible to enforce a "only
 193 local content" policy despite web designers urge to fetch programs
 194 from random sites on the Internet, like the one
 195 <a href="https://securityaffairs.co/wordpress/68966/hacking/browsealoud-plugin-hack.html">enabling
 196 the attack</a> reported by Scott Helme earlier this year.</p>
 197
 198 <p>Using CSP seem like an obvious thing for a site admin to implement
 199 to take some control over the information leak that occur when
 200 external sources are used to render web pages, it is a mystery more
 201 sites are not using CSP?  It is being
 202 <a href="https://www.w3.org/TR/CSP/">standardized under W3C</a> these
 203 days, and is supposed by most web browsers</p>
 204
 205 <p>I managed to find <a href="https://github.com/mozilla/django-csp">a
 206 Django middleware for implementing CSP</a> and was happy to discover
 207 it was already in Debian.  I plan to use it to add CSP support to the
 208 Frikanalen web site soon.</p>

 226       <div class="date"> 8th November 2018</div>
 227       <div class="body"><p>If you read my blog regularly, you probably know I am involved in
 228 running and developing the <a href="https://frikanalen.no/">Norwegian
 229 TV channel Frikanalen</a>.  It is an open channel, allowing everyone
 230 in Norway to publish videos on a TV channel with national coverage.
 231 You can think of it as Youtube for national television.
 232 In addition to distribution on RiksTV and Uninett, Frikanalen is also
 233 available as a Kodi addon.  The last few days I have updated the code
 234 to add more features.  A
 235 <a href="https://kodi.tv/addon/plugins-video-add-ons/frikanalen-nett-tv">new
 236 and improved version 0.0.3 Frikanalen addon</a> was just made
 237 available via the Kodi repositories.  This new version include a
 238 option to browse videos by category, as well as free text search
 239 in the video archive.  It will now also show the video duration in the
 240 video lists, which were missing earlier.  A new and experimental
 241 link to the HD video stream currently being worked on is provided, for
 242 those that want to see what the <a href="https://casparcg.com/">CasparCG</a>
 243 output look like.  The alternative is the SD video stream, generated
 244 using MLT.  CasparCG is controlled by our
 245 <a href="https://github.com/Frikanalen/mltplayout/">mltplayout
 246 server</a> which instead of talking to mlt is giving PLAY instructions
 247 to the CasparCG server when it is time to start a new program.</p>
 248
 249 <p>By now, you are probably wondering what kind of content is being
 250 played on the channel.  These days, it is filled with technical
 251 presentations like those from <a href="https://www.nuug.no/">NUUG</a>,
 252 <a href="https://www.debconf.org/">Debconf</a>, Makercon, and TED,
 253 but there are also some periods with

 274       <div class="body"><p>As part of my involvement in
 275 <a href="https://gitlab.com/OsloMet-ABI/nikita-noark5-core">the Nikita
 276 archive API project</a>, I've been importing a fairly large lump of
 277 emails into a test instance of the archive to see how well this would
 278 go.  I picked a subset of <a href="https://notmuchmail.org/">my
 279 notmuch email database</a>, all public emails sent to me via
 280 @lists.debian.org, giving me a set of around 216 000 emails to import.
 281 In the process, I had a look at the various attachments included in
 282 these emails, to figure out what to do with attachments, and noticed
 283 that one of the most common attachment formats do not have
 284 <a href="https://www.iana.org/assignments/media-types/media-types.xhtml">an
 285 official MIME type</a> registered with IANA/IETF.  The output from
 286 diff, ie the input for patch, is on the top 10 list of formats
 287 included in these emails.  At the moment people seem to use either
 288 text/x-patch or text/x-diff, but neither is officially registered.  It
 289 would be better if one official MIME type were registered and used
 290 everywhere.</p>
 291
 292 <p>To try to get one official MIME type for these files, I've brought
 293 up the topic on
 294 <a href="https://www.ietf.org/mailman/listinfo/media-types">the
 295 media-types mailing list</a>.  If you are interested in discussion
 296 which MIME type to use as the official for patch files, or involved in
 297 making software using a MIME type for patches, perhaps you would like
 298 to join the discussion?</p>

 319 <p>My current home stereo is a patchwork of various pieces I got on
 320 flee markeds over the years.  It is amazing what kind of equipment
 321 show up there.  I've been wondering for a while if it was possible to
 322 measure how well this equipment is working together, and decided to
 323 see how far I could get using free software.  After trawling the web I
 324 came across an article from DIY Audio and Video on
 325 <a href="https://www.diyaudioandvideo.com/Tutorial/SpeakerResponseTesting/">Speaker
 326 Testing and Analysis</a> describing how to test speakers, and it listing
 327 several software options, among them
 328 <a href="https://sourceforge.net/projects/audmes/">AUDio MEasurement
 329 System (AUDMES)</a>.  It is the only free software system I could find
 330 focusing on measuring speakers and audio frequency response.  In the
 331 process I also found an interesting article from NOVO on
 332 <a href="http://novo.press/understanding-speaker-specifications-and-frequency-response/">Understanding
 333 Speaker Specifications and Frequency Response</a> and an article from
 334 ecoustics on
 335 <a href="https://www.ecoustics.com/articles/understanding-speaker-frequency-response/">Understanding
 336 Speaker Frequency Response</a>, with a lot of information on what to
 337 look for and how to interpret the graphs.  Armed with this knowledge,
 338 I set out to measure the state of my speakers.</p>
 339
 340 <p>The first hurdle was that AUDMES hadn't seen a commit for 10 years
 341 and did not build with current compilers and libraries.  I got in
 342 touch with its author, who no longer was spending time on the program
 343 but gave me write access to the subversion repository on Sourceforge.
 344 The end result is that now the code build on Linux and is capable of
 345 saving and loading the collected frequency response data in CSV
 346 format.  The application is quite nice and flexible, and I was able to
 347 select the input and output audio interfaces independently.  This made
 348 it possible to use a USB mixer as the input source, while sending
 349 output via my laptop headphone connection.  I lacked the hardware and
 350 cabling to figure out a different way to get independent cabling to
 351 speakers and microphone.</p>
 352
 353 <p>Using this setup I could see how a large range of high frequencies
 354 apparently were not making it out of my speakers.  The picture show
 355 the frequency response measurement of one of the speakers.  Note the
 356 frequency lines seem to be slightly misaligned, compared to the CSV
 357 output from the program.  I can not hear several of these are high
 358 frequencies, according to measurement from
 359 <a href="http://freehearingtestsoftware.com">Free Hearing Test
 360 Software</a>, an freeware system to measure your hearing (still
 361 looking for a free software alternative), so I do not know if they are
 362 coming out out the speakers.  I thus do not quite know how to figure
 363 out if the missing frequencies is a problem with the microphone, the
 364 amplifier or the speakers, but I managed to rule out the audio card in my
 365 PC by measuring my Bose noise canceling headset using its own
 366 microphone.  This setup was able to see the high frequency tones, so
 367 the problem with my stereo had to be in the amplifier or speakers.</p>
 368
 369 <p>Anyway, to try to role out one factor I ended up picking up a new
 370 set of speakers at a flee marked, and these work a lot better than the
 371 old speakers, so I guess the microphone and amplifier is OK.  If you
 372 need to measure your own speakers, check out AUDMES.  If more people
 373 get involved, perhaps the project could become good enough to
 374 <a href="https://bugs.debian.org/910876">include in Debian</a>?  And if
 375 you know of some other free software to measure speakers and amplifier
 376 performance, please let me know.  I am aware of the freeware option
 377 <a href="https://www.roomeqwizard.com/">REW</a>, but I want something
 378 that can be developed also when the vendor looses interest.</p>

 396       <div class="date">21st October 2018</div>
 397       <div class="body"><p>Bittorrent is as far as I know, currently the most efficient way to
 398 distribute content on the Internet.  It is used all by all sorts of
 399 content providers, from national TV stations like
 400 <a href="https://www.nrk.no/">NRK</a>, Linux distributors like
 401 <a href="https://www.debian.org/">Debian</a> and
 402 <a href="https://www.ubuntu.com/">Ubuntu</a>, and of course the
 403 <a href="https://archive.org/">Internet archive</A>.
 404
 405 <p>Almost a month ago
 406 <a href="https://tracker.debian.org/pkg/vlc-plugin-bittorrent">a new
 407 package adding Bittorrent support to VLC</a> became available in
 408 Debian testing and unstable.  To test it, simply install it like
 409 this:</p>
 410
 411 <p><pre>
 412 apt install vlc-plugin-bittorrent
 413 </pre></p>
 414
 415 <p>Since the plugin was made available for the first time in Debian,
 416 several improvements have been made to it.  In version 2.2-4, now
 417 available in both testing and unstable, a desktop file is provided to
 418 teach browsers to start VLC when the user click on torrent files or
 419 magnet links.  The last part is thanks to me finally understanding
 420 what the strange x-scheme-handler style MIME types in desktop files
 421 are used for.  By adding x-scheme-handler/magnet to the MimeType entry
 422 in the desktop file, at least the browsers Firefox and Chromium will
 423 suggest to start VLC when selecting a magnet URI on a web page.  The
 424 end result is that now, with the plugin installed in Buster and Sid,
 425 one can visit any
 426 <a href="https://archive.org/details/CopyingIsNotTheft1080p">Internet
 427 Archive page with movies</a> using a web browser and click on the
 428 torrent link to start streaming the movie.</p>
 429
 430 <p>Note, there is still some misfeatures in the plugin.  One is the
 431 fact that it will hang and
 432 <a href="https://github.com/johang/vlc-bittorrent/issues/13">block VLC
 433 from exiting until the torrent streaming starts</a>.  Another is the
 434 fact that it
 435 <a href="https://github.com/johang/vlc-bittorrent/issues/9">will pick
 436 and play a random file in a multi file torrent</a>.  This is not
 437 always the video file you want.  Combined with the first it can be a
 438 bit hard to get the video streaming going.  But when it work, it seem
 439 to do a good job.</p>
 440
 441 <p>For the Debian packaging, I would love to find a good way to test
 442 if the plugin work with VLC using autopkgtest.  I tried, but do not
 443 know enough of the inner workings of VLC to get it working.  For now
 444 the autopkgtest script is only checking if the .so file was
 445 successfully loaded by VLC.  If you have any suggestions, please
 446 submit a patch to the Debian bug tracking system.</p>

 545       <div class="date"> 8th October 2018</div>
 546       <div class="body"><p>I have  earlier covered the basics of trusted timestamping using the
 547 'openssl ts' client.  See blog post for
 548 <a href="http://people.skolelinux.org/pere/blog/Public_Trusted_Timestamping_services_for_everyone.html">2014</a>,
 549 <a href="http://people.skolelinux.org/pere/blog/syslog_trusted_timestamp___chain_of_trusted_timestamps_for_your_syslog.html">2016</a>
 550 and
 551 <a href="http://people.skolelinux.org/pere/blog/Idea_for_storing_trusted_timestamps_in_a_Noark_5_archive.html">2017</a>
 552 for those stories.  But some times I want to integrate the timestamping
 553 in other code, and recently I needed to integrate it into Python.
 554 After searching a bit, I found
 555 <a href="https://dev.entrouvert.org/projects/python-rfc3161">the
 556 rfc3161 library</a> which seemed like a good fit, but I soon
 557 discovered it only worked for python version 2, and I needed something
 558 that work with python version 3.  Luckily I next came across
 559 <a href="https://github.com/trbs/rfc3161ng/">the rfc3161ng library</a>,
 560 a fork of the original rfc3161 library.  Not only is it working with
 561 python 3, it have fixed a few of the bugs in the original library, and
 562 it has an active maintainer.  I decided to wrap it up and make it
 563 <a href="https://tracker.debian.org/pkg/python-rfc3161ng">available in
 564 Debian</a>, and a few days ago it entered Debian unstable and testing.</p>
 565
 566 <p>Using the library is fairly straight forward.  The only slightly
 567 problematic step is to fetch the required certificates to verify the
 568 timestamp.  For some services it is straight forward, while for others
 569 I have not yet figured out how to do it.  Here is a small standalone
 570 code example based on of the integration tests in the library code:</p>

 574
 575 """
 576
 577 Python 3 script demonstrating how to use the rfc3161ng module to
 578 get trusted timestamps.
 579
 580 The license of this code is the same as the license of the rfc3161ng
 581 library, ie MIT/BSD.
