  25       <div class="body"><p>The chrpath package provide a simple command line tool to remove
  26 the rpath or runpath of compiled ELF program.  It is almost 10 years
  27 since I updated the code base, but I stumbled over the tool today, and
  28 decided it was time to move the code base from Subversion to git and
  29 find a new home for it, as the previous one (Debian Alioth) has been
  30 shut down.  I decided to go with
  31 <a href="https://codeberg.org/">Codeberg</a> this time, as it is my git
  32 service of choice these days, did a quick and dirty migration to git
  33 and updated the code with a few patches I found in the Debian bug
  34 tracker.  These are the release notes:</p>
  35
  36 <p>New in 0.17 released 2023-11-10:</p>
  37
  38 <ul>
  39 <li>Moved project to Codeberg, as Alioth is shut down.</li>
  40 <li>Add Solaris support (use &lt;sys/byteorder.h> instead of &lt;byteswap.h>).
  41    Patch from Rainer Orth.</li>
  42 <li>Added missing newline from printf() line.  Patch from Frank Dana.</li>
  43 <li>Corrected handling of multiple ELF sections. Patch from Frank Dana.</li>
  44 <li>Updated build rules for .deb.  Partly based on patch from djcj.</li>

  66       <div class="date"> 5th November 2023</div>
  67       <div class="body"><p>All the books I have published so far has been using
  68 <a href="https://docbook.org/">DocBook</a> somewhere in the process.
  69 For the first book, the source format was DocBook, while for every
  70 later book it was an intermediate format used as the stepping stone to
  71 be able to present the same manuscript in several formats, on paper,
  72 as ebook in ePub format, as a HTML page and as a PDF file either for
  73 paper production or for Internet consumption.  This is made possible
  74 with a wide variety of free software tools with DocBook support in
  75 Debian.  The source format of later books have been docx via rst,
  76 Markdown, Filemaker and Asciidoc, and for all of these I was able to
  77 generate a suitable DocBook file for further processing using
  78 <a href="https://tracker.debian.org/pkg/pandoc">pandoc</a>,
  79 <a href="https://tracker.debian.org/pkg/asciidoc">a2x</a> and
  80 <a href="https://tracker.debian.org/pkg/asciidoctor">asciidoctor</a>,
  81 as well as rendering using
  82 <a href="https://tracker.debian.org/pkg/xmlto">xmlto</a>,
  83 <a href="https://tracker.debian.org/pkg/dbtoepub">dbtoepub</a>,
  84 <a href="https://tracker.debian.org/pkg/dblatex">dblatex</a>,
  85 <a href="https://tracker.debian.org/pkg/docbook-xsl">docbook-xsl</a> and
  86 <a href="https://tracker.debian.org/pkg/fop">fop</a>.</p>
  87
  88 <p>Most of the <a href="http://www.hungry.com/~pere/publisher/">books I
  89 have published</a> are translated books, with English as the source
  90 language.  The use of
  91 <a href="https://tracker.debian.org/pkg/po4a">po4a</a> to
  92 handle translations using the gettext PO format has been a blessing,
  93 but publishing translated books had triggered the need to ensure the
  94 DocBook tools handle relevant languages correctly.  For every new
  95 language I have published, I had to submit patches dblatex, dbtoepub
  96 and docbook-xsl fixing incorrect language and country specific issues
  97 in the framework themselves.  Typically this has been missing keywords
  98 like 'figure' or sort ordering of index entries.  After a while it
  99 became tiresome to only discover issues like this by accident, and I
 100 decided to write a DocBook "test framework" exercising various
 101 features of DocBook and allowing me to see all features exercised for
 102 a given language.  It consist of a set of DocBook files, a version 4
 103 book, a version 5 book, a v4 book set, a v4 selection of problematic
 104 tables, one v4 testing sidefloat and finally one v4 testing a book of
 105 articles.  The DocBook files are accompanied with a set of build rules
 106 for building PDF using dblatex and docbook-xsl/fop, HTML using xmlto
 107 or docbook-xsl and epub using dbtoepub.  The result is a set of files
 108 visualizing footnotes, indexes, table of content list, figures,
 109 formulas and other DocBook features, allowing for a quick review on
 110 the completeness of the given locale settings.  To build with a
 111 different language setting, all one need to do is edit the lang= value
 112 in the .xml file to pick a different ISO 639 code value and run
 113 'make'.</p>
 114
 115 <p>The <a href="https://codeberg.org/pere/docbook-example/">test framework
 116 source code</a> is available from Codeberg, and a generated set of
 117 presentations of the various examples is available as Codeberg static
 118 web pages at
 119 <a href="https://pere.codeberg.page/docbook-example/">https://pere.codeberg.page/docbook-example/</a>.
 120 Using this test framework I have been able to discover and report
 121 several bugs and missing features in various tools, and got a lot of
 122 them fixed.  For example I got Northern Sami keywords added to both
 123 docbook-xsl and dblatex, fixed several typos in Norwegian bokmål and
 124 Norwegian Nynorsk, support for non-ascii title IDs added to pandoc,
 125 Norwegian index sorting support fixed in xindy and initial Norwegian
 126 Bokmål support added to dblatex.  Some issues still remains, though.
 127 Default index sorting rules are still broken in several tools, so the
 128 Norwegian letters æ, ø and å are more often than not sorted properly
 129 in the book index.</p>
 130
 131 <p>The test framework recently received some more polish, as part of
 132 publishing my latest book.  This book contained a lot of fairly
 133 complex tables, which exposed bugs in some of the tools.  This made me
 134 add a new test file with various tables, as well as spend some time to
 135 brush up the build rules.  My goal is for the test framework to
 136 exercise all DocBook features to make it easier to see which features
 137 work with different processors, and hopefully get them all to support
 138 the full set of DocBook features.  Feel free to send patches to extend
 139 the test set, and test it with your favorite DocBook processor.

 192 <p>I 1979 leverte Ole-Erik Yrvin en hovedfagsoppgave for Cand. Scient.
 193   ved Institutt for sosiologi på Universitetet i Oslo på oppdrag fra
 194   Forbruker- og administrasjonsdepartementet. Oppgaven evaluerte
 195   Angrefristloven fra 1972, og det han oppdaget førte til at loven ble
 196   endret fire år senere.</p>
 197
 198 <p>Jeg har kjent Ole-Erik en stund, og synes det var trist at hans
 199   oppgave ikke lenger er tilgjengelig, hverken fra oppdragsgiver
 200   eller fra universitetet.  Hans forsøk på å få den avbildet og lagt
 201   ut på Internett har vist seg fånyttes, så derfor tilbød jeg meg for
 202   en stund tilbake å publisere den og gjøre den tilgjengelig med
 203   fribruksvilkår på Internett.  Det er nå klart, og hovedfagsoppgaven
 204   er tilgjengelig blant annet via <a
 205   href="http://www.hungry.com/~pere/publisher/">min liste over
 206   publiserte bøker</a>, både som nettside,
 207   <a href="https://www.lulu.com/search?contributor=Ole-Erik+Yrvin">digital
 208   bok i ePub-format og på papir fra lulu.com</a>.  Jeg regner med at
 209   den også vil dukke opp på nettbokhandlere i løpet av en måned eller
 210   to.</p>
 211
 212 <p>Alle tabeller og figurer er gjenskapt for bedre lesbarhet, noen
 213   skrivefeil rettet opp og mange referanser har fått flere detaljer
 214   som ISBN-nummer og DOI-referanse.  Selv om jeg ikke regner med at
 215   dette blir en kioskvelter, så håper jeg denne nye utgaven kan komme
 216   fremtiden til glede.</p>

 236       <div class="date"> 7th September 2023</div>
 237       <div class="body"><p>Medlemmene av Norges regjering har demonstert de siste månedene at
 238 habilitetsvureringer ikke er deres sterke side og det gjelder både
 239 Arbeiderpartiets og Senterpartiers representater. Det er heldigvis
 240 enklere i det private, da inhabilitetsreglene kun gjelder de som
 241 jobber for folket, ikke seg selv.  Sist ut er utenriksminister
 242 Huitfeldt.  I går kom nyheten om at
 243 <a href="https://www.nrk.no/nyheter/riksadvokaten_-okokrim-nestsjef-kan-behandle-huitfeldt-saken-1.16545162">Riksadvokaten
 244 har konkludert med at nestsjefen i Økokrim kan behandle sak om
 245 habilitet og innsidekunnskap</a> for Huitfeldt, på tross av at hans
 246 overordnede, sjefen for Økokrim, har meldt seg inhabil i saken.  Dette
 247 er litt rart.  I veilednigen
 248 «<a href="https://www.regjeringen.no/globalassets/upload/krd/vedlegg/komm/veiledere/habilitet_i_kommuner_og_fylkeskommuner.pdf">Habilitet
 249 i kommuner og fylkeskommuner</a>» av Kommunal- og regionaldepartementet
 250 forteller de hva som gjelder, riktig nok gjelder veiledningen ikke for
 251 Økokrim som jo ikke er kommune eller fylkeskommune, men jeg får ikke
 252 inntrykk av at dette er regler som kun gjelder for kommune og
 253 fylkeskommune:
 254
 255 <blockquote>
 256 <p>«<strong>2.1 Oversikt over inhabilitetsgrunnlagene</strong>
 257
 258 <p>De alminnelige reglene om inhabilitet for den offentlige
 259 forvaltningen er gitt i
 260 <a href="https://lovdata.no/dokument/NL/lov/1967-02-10/KAPITTEL_2#KAPITTEL_2">forvaltningsloven
 261 §§ 6 til 10</a>. Forvaltningslovens hovedregel om inhabilitet framgår
 262 av § 6. Her er det gitt tre ulike grunnlag som kan føre til at en
 263 tjenestemann eller folkevalgt blir inhabil. I § 6 første ledd
 264 bokstavene a til e er det oppstilt konkrete tilknytningsforhold mellom
 265 tjenestemannen og saken eller sakens parter som automatisk fører til
 266 inhabilitet. Annet ledd oppstiller en skjønnsmessig regel om at
 267 tjenestemannen også kan bli inhabil etter en konkret vurdering av
 268 inhabilitetsspørsmålet, der en lang rekke momenter kan være
 269 relevante. I tredje ledd er det regler om såkalt avledet
 270 inhabilitet. Det vil si at en underordnet tjenestemann blir inhabil
 271 fordi en overordnet er inhabil.»</p>
 272 </blockquote>
 273
 274 <p>Loven sier ganske enkelt «Er den overordnede tjenestemann ugild,
 275 kan avgjørelse i saken heller ikke treffes av en direkte underordnet
 276 tjenestemann i samme forvaltningsorgan.»  Jeg antar tanken er at en
 277 underordnet vil stå i fare for å tilpasse sine konklusjoner til det
 278 overordnet vil ha fordel av, for å fortsatt ha et godt forhold til sin
 279 overordnede.  Men jeg er ikke jurist og forstår nok ikke kompliserte
 280 juridiske vurderinger.  For å sitere «Kamerat Napoleon» av George
 281 Orwell: «Alle dyr er like, men noen dyr er likere enn andre».

 295       <div class="date">10th August 2023</div>
 296       <div class="body"><p>I still enjoy <a href="https://kodi.tv/">Kodi</a> and
 297 <a href="https://libreelec.tv/">LibreELEC</a> as my multimedia center
 298 at home.  Sadly two of the services I really would like to use from
 299 within Kodi are not easily available.  The most wanted add-on would be
 300 one making <a href="https://archive.org/">The Internet Archive</a>
 301 available, and it has
 302 <a href="https://kodi.wiki/view/Add-on:Internet_Archive">not been
 303 working</a> for many years.  The second most wanted add-on is one
 304 using <a href="https://invidious.io/">the Invidious privacy enhanced
 305 Youtube frontent</a>.  A plugin for this has been partly working, but
 306 not been kept up to date in the Kodi add-on repository, and its
 307 upstream seem to have given it up in April this year, when the git
 308 repository was closed.  A few days ago I got tired of this sad state
 309 of affairs and decided to
 310 <a href="https://github.com/petterreinholdtsen/kodi-invidious-plugin">have
 311 a go at improving the Invidious add-on</a>.  As
 312 <a href="https://github.com/iv-org/invidious/issues/3872">Google has
 313 already attacked</a> the Invidious concept, so it need all the support
 314 if can get.  My small contribution here is to improve the service
 315 status on Kodi.</p>
 316
 317 <p>I added support to the Invidious add-on for automatically picking a
 318 working Invidious instance, instead of requiring the user to specify
 319 the URL to a specific instance after installation.  I also had a look
 320 at the set of patches floating around in the various forks on github,
 321 and decided to clean up at least some of the features I liked and
 322 integrate them into my new release branch.  Now the plugin can handle
 323 channel and short video items in search results.  Earlier it could
 324 only handle single video instances in the search response.  I also
 325 brushed up the set of metadata displayed a bit, but hope I can figure
 326 out how to get more relevant metadata displayed.</p>
 327
 328 <p>Because I only use Kodi 20 myself, I only test on version 20 and am
 329 only motivated to ensure version 20 is working.  Because of API changes
 330 between version 19 and 20, I suspect it will fail with earlier Kodi
 331 versions.</p>
 332
 333 <p>I already
 334 <a href="https://github.com/xbmc/repo-plugins/pull/4363">asked to have
 335 the add-on added</a> to the official Kodi 20 repository, and is
 336 waiting to heard back from the repo maintainers.</p>

 362 are obviously calling out from my machine, like the NTP network based
 363 clock adjusting system and Tor to reach other Tor clients, but others
 364 were more dubious.  For example, the KDE Window manager try to look up
 365 the host name in DNS, for no apparent reason, but if this lookup is
 366 blocked the KDE desktop get periodically stuck when I use it.  Another
 367 surprise was how much Firefox call home directly to mozilla.com,
 368 mozilla.net and googleapis.com, to mention a few, when I visit other
 369 web pages.  This direct connection happen even if I told Firefox to
 370 always use a proxy, and the proxy setting is ignored for this traffic.
 371 Other surprising connections come from audacity and dirmngr (I do not
 372 use Gnome).  It took some trial and error to get a good default set of
 373 permissions.  Without it, I would get popups asking for permissions at
 374 any time, also the most inconvenient ones where I am in the middle of
 375 a time sensitive gaming session.</p>
 376
 377 <p>I suspect some application developers should rethink when then need
 378 to use network connections or DNS lookups, and recommend testing
 379 OpenSnitch (only <tt>apt install opensnitch</tt> away in Debian
 380 Bookworm) to locate and report any surprising Internet connections on
 381 your desktop machine.</p>
 382
 383 <p>At the moment the upstream developer and Debian package maintainer
 384 is working on making the system more reliable in Debian, by enabling
 385 the eBPF kernel module to track processes and connections instead of
 386 depending in content in /proc/.  This should enter unstable fairly
 387 soon.</p>

 412       <div class="date">19th May 2023</div>
 413       <div class="body"><p>There is a European standard for reading utility meters like water,
 414 gas, electricity or heat distribution meters.  The
 415 <a href="https://en.wikipedia.org/wiki/Meter-Bus">Meter-Bus standard
 416 (EN 13757-2, EN 13757-3 and EN 13757–4)</a> provide a cross vendor way
 417 to talk to and collect meter data.  I ran into this standard when I
 418 wanted to monitor some heat distribution meters, and managed to find
 419 free software that could do the job.  The meters in question broadcast
 420 encrypted messages with meter information via radio, and the hardest
 421 part was to track down the encryption keys from the vendor.  With this
 422 in place I could set up a MQTT gateway to submit the meter data for
 423 graphing.</p>
 424
 425 <p>The free software systems in question,
 426 <a href="https://tracker.debian.org/pkg/rtl-wmbus">rtl-wmbus</a> to
 427 read the messages from a software defined radio, and
 428 <a href="https://tracker.debian.org/pkg/wmbusmeters">wmbusmeters</a> to
 429 decrypt and decode the content of the messages, is working very well
 430 and allowe me to get frequent updates from my meters.  I got in touch
 431 with upstream last year to see if there was any interest in publishing
 432 the packages via Debian.  I was very happy to learn that Fredrik
 433 Öhrström volunteered to maintain the packages, and I have since
 434 assisted him in getting Debian package build rules in place as well as
 435 sponsoring the packages into the Debian archive.  Sadly we completed
 436 it too late for them to become part of the next stable Debian release
 437 (Bookworm).  The wmbusmeters package just cleared the NEW queue.  It
 438 will need some work to fix a built problem, but I expect Fredrik will
 439 find a solution soon.</p>
 440
 441 <p>If you got a infrastructure meter supporting the Meter Bus
 442 standard, I strongly recommend having a look at these nice
 443 packages.</p>

 461       <div class="date">14th May 2023</div>
 462       <div class="body"><p>The LinuxCNC project is making headway these days.  A lot of
 463 patches and issues have seen activity on
 464 <a href="https://github.com/LinuxCNC/linuxcnc/">the project github
 465 pages</a> recently.  A few weeks ago there was a developer gathering
 466 over at the <a href="https://tormach.com/">Tormach</a> headquarter in
 467 Wisconsin, and now we are planning a new gathering in Norway.  If you
 468 wonder what LinuxCNC is, lets quote Wikipedia:</p>
 469
 470 <blockquote>
 471 "LinuxCNC is a software system for numerical control of
 472 machines such as milling machines, lathes, plasma cutters, routers,
 473 cutting machines, robots and hexapods. It can control up to 9 axes or
 474 joints of a CNC machine using G-code (RS-274NGC) as input. It has
 475 several GUIs suited to specific kinds of usage (touch screen,
 476 interactive development)."
 477 </blockquote>
 478
 479 <p>The Norwegian developer gathering take place the weekend June 16th
 480 to 18th this year, and is open for everyone interested in contributing
 481 to LinuxCNC.  Up to date information about the gathering can be found
 482 in
 483 <a href="https://sourceforge.net/p/emc/mailman/emc-developers/thread/sa64jp06nob.fsf%40hjemme.reinholdtsen.name/#msg37837251">the
 484 developer mailing list thread</a> where the gathering was announced.

 509       <div class="date">13th May 2023</div>
 510       <div class="body"><p>A bit delayed,
 511 <a href="https://tracker.debian.org/pkg/opensnitch">the interactive
 512 application firewall OpenSnitch</a> package in Debian now got the
 513 latest fixes ready for Debian Bookworm.  Because it depend on a
 514 package missing on some architectures, the autopkgtest check of the
 515 testing migration script did not understand that the tests were
 516 actually working, so the migration was delayed.  A bug in the package
 517 dependencies is also fixed, so those installing the firewall package
 518 (opensnitch) now also get the GUI admin tool (python3-opensnitch-ui)
 519 installed by default.  I am very grateful to Gustavo Iñiguez Goya for
 520 his work on getting the package ready for Debian Bookworm.</p>
 521
 522 <p>Armed with this package I have discovered some surprising
 523 connections from programs I believed were able to work completly
 524 offline, and it has already proven its worth, at least to me.  If you
 525 too want to get more familiar with the kind of programs using
 526 Internett connections on your machine, I recommend testing <tt>apt
 527 install opensnitch</tt> in Bookworm and see what you think.</p>
 528
 529 <p>The package is still not able to build its eBPF module within
 530 Debian.  Not sure how much work it would be to get it working, but
 531 suspect some kernel related packages need to be extended with more
 532 header files to get it working.</p>

 550       <div class="date">23rd April 2023</div>
 551       <div class="body"><p>While visiting a convention during Easter, it occurred to me that
 552 it would be great if I could have a digital Dictaphone with
 553 transcribing capabilities, providing me with texts to cut-n-paste into
 554 stuff I need to write.  The background is that long drives often bring
 555 up the urge to write on texts I am working on, which of course is out
 556 of the question while driving.  With the release of
 557 <a href="https://github.com/openai/whisper/">OpenAI Whisper</a>, this
 558 seem to be within reach with Free Software, so I decided to give it a
 559 go.  OpenAI Whisper is a Linux based neural network system to read in
 560 audio files and provide text representation of the speech in that
 561 audio recording.  It handle multiple languages and according to its
 562 creators even can translate into a different language than the spoken
 563 one.  I have not tested the latter feature.  It can either use the CPU
 564 or a GPU with CUDA support.  As far as I can tell, CUDA in practice
 565 limit that feature to NVidia graphics cards.  I have few of those, as
 566 they do not work great with free software drivers, and have not tested
 567 the GPU option.  While looking into the matter, I did discover some
 568 work to provide CUDA support on non-NVidia GPUs, and some work with
 569 the library used by Whisper to port it to other GPUs, but have not
 570 spent much time looking into GPU support yet.  I've so far used an old
 571 X220 laptop as my test machine, and only transcribed using its
 572 CPU.</p>
 573
 574 <p>As it from a privacy standpoint is unthinkable to use computers
 575 under control of someone else (aka a "cloud" service) to transcribe
 576 ones thoughts and personal notes, I want to run the transcribing
 577 system locally on my own computers.  The only sensible approach to me
 578 is to make the effort I put into this available for any Linux user and
 579 to upload the needed packages into Debian.  Looking at Debian Bookworm, I
 580 discovered that only three packages were missing,
 581 <a href="https://bugs.debian.org/1034307">tiktoken</a>,
 582 <a href="https://bugs.debian.org/1034144">triton</a>, and
 583 <a href="https://bugs.debian.org/1034091">openai-whisper</a>.  For a while
 584 I also believed
 585 <a href="https://bugs.debian.org/1034286">ffmpeg-python</a> was
 586 needed, but as its
 587 <a href="https://github.com/kkroening/ffmpeg-python/issues/760">upstream
 588 seem to have vanished</a> I found it safer
 589 <a href="https://github.com/openai/whisper/pull/1242">to rewrite
 590 whisper</a> to stop depending on in than to introduce ffmpeg-python
 591 into Debian.  I decided to place these packages under the umbrella of
 592 <a href="https://salsa.debian.org/deeplearning-team">the Debian Deep
 593 Learning Team</a>, which seem like the best team to look after such
 594 packages.  Discussing the topic within the group also made me aware
 595 that the triton package was already a future dependency of newer
 596 versions of the torch package being planned, and would be needed after
 597 Bookworm is released.</p>
 598
 599 <p>All required code packages have been now waiting in
 600 <a href="https://ftp-master.debian.org/new.html">the Debian NEW
 601 queue</a> since Wednesday, heading for Debian Experimental until
 602 Bookworm is released.  An unsolved issue is how to handle the neural
 603 network models used by Whisper.  The default behaviour of Whisper is
 604 to require Internet connectivity and download the model requested to
 605 <tt>~/.cache/whisper/</tt> on first invocation.  This obviously would
 606 fail <a href="https://people.debian.org/~bap/dfsg-faq.html">the
 607 deserted island test of free software</a> as the Debian packages would
 608 be unusable for someone stranded with only the Debian archive and solar
 609 powered computer on a deserted island.</p>
 610
 611 <p>Because of this, I would love to include the models in the Debian
 612 mirror system.  This is problematic, as the models are very large
 613 files, which would put a heavy strain on the Debian mirror
 614 infrastructure around the globe.  The strain would be even higher if
 615 the models change often, which luckily as far as I can tell they do
 616 not.  The small model, which according to its creator is most useful
 617 for English and in my experience is not doing a great job there
 618 either, is 462 MiB (deb is 414 MiB).  The medium model, which to me
 619 seem to handle English speech fairly well is 1.5 GiB (deb is 1.3 GiB)
 620 and the large model is 2.9 GiB (deb is 2.6 GiB).  I would assume
 621 everyone with enough resources would prefer to use the large model for
 622 highest quality.  I believe the models themselves would have to go
 623 into the non-free part of the Debian archive, as they are not really
 624 including any useful source code for updating the models.  The
 625 "source", aka the model training set, according to the creators
 626 consist of "680,000 hours of multilingual and multitask supervised
 627 data collected from the web", which to me reads material with both
 628 unknown copyright terms, unavailable to the general public.  In other
 629 words, the source is not available according to the Debian Free
 630 Software Guidelines and the model should be considered non-free.</p>
 631
 632 <p>I asked the Debian FTP masters for advice regarding uploading a
 633 model package on their IRC channel, and based on the feedback there it
 634 is still unclear to me if such package would be accepted into the
 635 archive.  In any case I wrote build rules for a
 636 <a href="https://salsa.debian.org/deeplearning-team/openai-whisper-model">OpenAI
 637 Whisper model package</a> and
 638 <a href="https://github.com/openai/whisper/pull/1257">modified the
 639 Whisper code base</a> to prefer shared files under <tt>/usr/</tt> and
 640 <tt>/var/</tt> over user specific files in <tt>~/.cache/whisper/</tt>
 641 to be able to use these model packages, to prepare for such
 642 possibility.  One solution might be to include only one of the models
 643 (small or medium, I guess) in the Debian archive, and ask people to
 644 download the others from the Internet.  Not quite sure what to do
 645 here, and advice is most welcome (use the debian-ai mailing list).</p>
 646
 647 <p>To make it easier to test the new packages while I wait for them to
 648 clear the NEW queue, I created an APT source targeting bookworm.  I
 649 selected Bookworm instead of Bullseye, even though I know the latter
 650 would reach more users, is that some of the required dependencies are
 651 missing from Bullseye and I during this phase of testing did not want
 652 to backport a lot of packages just to get up and running.</p>
 653
 654 <p>Here is a recipe to run as user root if you want to test OpenAI
 655 Whisper using Debian packages on your Debian Bookworm installation,
 656 first adding the APT repository GPG key to the list of trusted keys,
 657 then setting up the APT repository and finally installing the packages
 658 and one of the models:</p>
 659
 660 <p><pre>
 661 curl https://geekbay.nuug.no/~pere/openai-whisper/D78F5C4796F353D211B119E28200D9B589641240.asc \
 662   -o /etc/apt/trusted.gpg.d/pere-whisper.asc
 663 mkdir -p /etc/apt/sources.list.d
 664 cat > /etc/apt/sources.list.d/pere-whisper.list &lt;&lt;EOF
 665 deb https://geekbay.nuug.no/~pere/openai-whisper/ bookworm main
 666 deb-src https://geekbay.nuug.no/~pere/openai-whisper/ bookworm main
 667 EOF
 668 apt update
 669 apt install openai-whisper
 670 </pre></p>
 671
 672 <p>The package work for me, but have not yet been tested on any other
 673 computer than my own.  With it, I have been able to (badly) transcribe
 674 a 2 minute 40 second Norwegian audio clip to test using the small
 675 model.  This took 11 minutes and around 2.2 GiB of RAM.  Transcribing
 676 the same file with the medium model gave a accurate text in 77 minutes
 677 using around 5.2 GiB of RAM.  My test machine had too little memory to
 678 test the large model, which I believe require 11 GiB of RAM.  In
 679 short, this now work for me using Debian packages, and I hope it will
 680 for you and everyone else once the packages enter Debian.</p>
 681
 682 <p>Now I can start on the audio recording part of this project.</p>
