  24       <div class="date"> 5th November 2023</div>
  25       <div class="body"><p>All the books I have published so far has been using
  26 <a href="https://docbook.org/">DocBook</a> somewhere in the process.
  27 For the first book, the source format was DocBook, while for every
  28 later book it was an intermediate format used as the stepping stone to
  29 be able to present the same manuscript in several formats, on paper,
  30 as ebook in ePub format, as a HTML page and as a PDF file either for
  31 paper production or for Internet consumption.  This is made possible
  32 with a wide variety of free software tools with DocBook support in
  33 Debian.  The source format of later books have been docx via rst,
  34 Markdown, Filemaker and Asciidoc, and for all of these I was able to
  35 generate a suitable DocBook file for further processing using pandoc,
  36 a2x and asciidoctor, as well as rendering using
  37 <a href="https://tracker.debian.org/pkg/xmlto">xmlto</a>,
  38 <a href="https://tracker.debian.org/pkg/dbtoepub">dbtoepub</a>,
  39 <a href="https://tracker.debian.org/pkg/dblatex">dblatex</a>,
  40 <a href="https://tracker.debian.org/pkg/dblatex">docbook-xsl</a> and
  41 <a href="https://tracker.debian.org/pkg/fop">fop</a>.</p>
  42
  43 <p>Most of the books I have published are translated books, with
  44 English as the source language.  The use of
  45 <a href="https://tracker.debian.org/pkg/po4a">po4a</a> to
  46 handle translations using the gettext PO format has been a blessing,
  47 but publishing translated books had triggered the need to ensure the
  48 DocBook tools handle relevant languages correctly.  For every new
  49 language I have published, I had to submit patches dblatex, dbtoepub
  50 and docbook-xsl fixing incorrect language and country specific issues
  51 in the framework themselves.  Typically this has been missing keywords
  52 like 'figure' or sort ordering of index entries.  After a while it
  53 became tiresome to only discover issues like this by accident, and I
  54 decided to write a DocBook "test framework" exercising various
  55 features of DocBook and allowing me to see all features exercised for
  56 a given language.  It consist of a set of DocBook files, a version 4
  57 book, a version 5 book, a v4 book set, a v4 selection of problematic
  58 tables, one v4 testing sidefloat and finally one v4 testing a book of
  59 articles.  The DocBook files are accompanied with a set of build rules
  60 for building PDF using dblatex and docbook-xsl/fop, HTML using xmlto
  61 or docbook-xsl and epub using dbtoepub.  The result is a set of files
  62 visualizing footnotes, indexes, table of content list, figures,
  63 formulas and other DocBook features, allowing for a quick review on
  64 the completeness of the given locale settings.  To build with a
  65 different language setting, all one need to do is edit the lang= value
  66 in the .xml file to pick a different ISO 639 code value and run
  67 'make'.</p>
  68
  69 <p>The <a href="https://codeberg.org/pere/docbook-example/">test framework
  70 source code</a> is available from Codeberg, and a generated set of
  71 presentations of the various examples is available as Codeberg static
  72 web pages at
  73 <a href="https://pere.codeberg.page/docbook-example/">https://pere.codeberg.page/docbook-example/</a>.
  74 Using this test framework I have been able to discover and report
  75 several bugs and missing features in various tools, and got a lot of
  76 them fixed.  For example I got Northern Sami keywoards added to both
  77 docbook-xsl and dblatex, fixed several typos in Norwegian bokmål and
  78 Norwegian Nynorsk, support for non-ascii title IDs added to pandoc,
  79 Norwegian index sorting support fixed in xindy and initial Norwegian
  80 Bokmål support added to dblatex.  Some issues still remains, though.
  81 Default index sorting rules are still broken in several tools, so the
  82 Norwegian letters æ, ø and å are more often than not sorted properly
  83 in the book index.</p>
  84
  85 <p>The test framework recently received some more polish, as part of
  86 publishing my latest book.  This book contained a lot of fairly
  87 complex tables, which exposed bugs in some of the tools.  This made me
  88 add a new test file with various tables, as well as spend some time to
  89 brush up the build rules.  My goal is for the test framework to
  90 exercise all DocBook features to make it easier to see which features
  91 work with different processors, and hopefully get them all to support
  92 the full set of DocBook features.  Feel free to send patches to extend
  93 the test set, and test it with your favorite DocBook processor.

 143 <p>I 1979 leverte Ole-Erik Yrvin en hovedfagsoppgave for Cand. Scient.
 144   ved Institutt for sosiologi på Universitetet i Oslo på oppdrag fra
 145   Forbruker- og administrasjonsdepartementet. Oppgaven evaluerte
 146   Angrefristloven fra 1972, og det han oppdaget førte til at loven ble
 147   endret fire år senere.</p>
 148
 149 <p>Jeg har kjent Ole-Erik en stund, og synes det var trist at hans
 150   oppgave ikke lenger er tilgjengelig, hverken fra oppdragsgiver
 151   eller fra universitetet.  Hans forsøk på å få den avbildet og lagt
 152   ut på Internett har vist seg fånyttes, så derfor tilbød jeg meg for
 153   en stund tilbake å publisere den og gjøre den tilgjengelig med
 154   fribruksvilkår på Internett.  Det er nå klart, og hovedfagsoppgaven
 155   er tilgjengelig blant annet via <a
 156   href="http://www.hungry.com/~pere/publisher/">min liste over
 157   publiserte bøker</a>, både som nettside,
 158   <a href="https://www.lulu.com/search?contributor=Ole-Erik+Yrvin">digital
 159   bok i ePub-format og på papir fra lulu.com</a>.  Jeg regner med at
 160   den også vil dukke opp på nettbokhandlere i løpet av en måned eller
 161   to.</p>
 162
 163 <p>Alle tabeller og figurer er gjenskapt for bedre lesbarhet, noen
 164   skrivefeil rettet opp og mange referanser har fått flere detaljer
 165   som ISBN-nummer og DOI-referanse.  Selv om jeg ikke regner med at
 166   dette blir en kioskvelter, så håper jeg denne nye utgaven kan komme
 167   fremtiden til glede.</p>

 187       <div class="date"> 7th September 2023</div>
 188       <div class="body"><p>Medlemmene av Norges regjering har demonstert de siste månedene at
 189 habilitetsvureringer ikke er deres sterke side og det gjelder både
 190 Arbeiderpartiets og Senterpartiers representater. Det er heldigvis
 191 enklere i det private, da inhabilitetsreglene kun gjelder de som
 192 jobber for folket, ikke seg selv.  Sist ut er utenriksminister
 193 Huitfeldt.  I går kom nyheten om at
 194 <a href="https://www.nrk.no/nyheter/riksadvokaten_-okokrim-nestsjef-kan-behandle-huitfeldt-saken-1.16545162">Riksadvokaten
 195 har konkludert med at nestsjefen i Økokrim kan behandle sak om
 196 habilitet og innsidekunnskap</a> for Huitfeldt, på tross av at hans
 197 overordnede, sjefen for Økokrim, har meldt seg inhabil i saken.  Dette
 198 er litt rart.  I veilednigen
 199 «<a href="https://www.regjeringen.no/globalassets/upload/krd/vedlegg/komm/veiledere/habilitet_i_kommuner_og_fylkeskommuner.pdf">Habilitet
 200 i kommuner og fylkeskommuner</a>» av Kommunal- og regionaldepartementet
 201 forteller de hva som gjelder, riktig nok gjelder veiledningen ikke for
 202 Økokrim som jo ikke er kommune eller fylkeskommune, men jeg får ikke
 203 inntrykk av at dette er regler som kun gjelder for kommune og
 204 fylkeskommune:
 205
 206 <blockquote>
 207 <p>«<strong>2.1 Oversikt over inhabilitetsgrunnlagene</strong>
 208
 209 <p>De alminnelige reglene om inhabilitet for den offentlige
 210 forvaltningen er gitt i
 211 <a href="https://lovdata.no/dokument/NL/lov/1967-02-10/KAPITTEL_2#KAPITTEL_2">forvaltningsloven
 212 §§ 6 til 10</a>. Forvaltningslovens hovedregel om inhabilitet framgår
 213 av § 6. Her er det gitt tre ulike grunnlag som kan føre til at en
 214 tjenestemann eller folkevalgt blir inhabil. I § 6 første ledd
 215 bokstavene a til e er det oppstilt konkrete tilknytningsforhold mellom
 216 tjenestemannen og saken eller sakens parter som automatisk fører til
 217 inhabilitet. Annet ledd oppstiller en skjønnsmessig regel om at
 218 tjenestemannen også kan bli inhabil etter en konkret vurdering av
 219 inhabilitetsspørsmålet, der en lang rekke momenter kan være
 220 relevante. I tredje ledd er det regler om såkalt avledet
 221 inhabilitet. Det vil si at en underordnet tjenestemann blir inhabil
 222 fordi en overordnet er inhabil.»</p>
 223 </blockquote>
 224
 225 <p>Loven sier ganske enkelt «Er den overordnede tjenestemann ugild,
 226 kan avgjørelse i saken heller ikke treffes av en direkte underordnet
 227 tjenestemann i samme forvaltningsorgan.»  Jeg antar tanken er at en
 228 underordnet vil stå i fare for å tilpasse sine konklusjoner til det
 229 overordnet vil ha fordel av, for å fortsatt ha et godt forhold til sin
 230 overordnede.  Men jeg er ikke jurist og forstår nok ikke kompliserte
 231 juridiske vurderinger.  For å sitere «Kamerat Napoleon» av George
 232 Orwell: «Alle dyr er like, men noen dyr er likere enn andre».

 246       <div class="date">10th August 2023</div>
 247       <div class="body"><p>I still enjoy <a href="https://kodi.tv/">Kodi</a> and
 248 <a href="https://libreelec.tv/">LibreELEC</a> as my multimedia center
 249 at home.  Sadly two of the services I really would like to use from
 250 within Kodi are not easily available.  The most wanted add-on would be
 251 one making <a href="https://archive.org/">The Internet Archive</a>
 252 available, and it has
 253 <a href="https://kodi.wiki/view/Add-on:Internet_Archive">not been
 254 working</a> for many years.  The second most wanted add-on is one
 255 using <a href="https://invidious.io/">the Invidious privacy enhanced
 256 Youtube frontent</a>.  A plugin for this has been partly working, but
 257 not been kept up to date in the Kodi add-on repository, and its
 258 upstream seem to have given it up in April this year, when the git
 259 repository was closed.  A few days ago I got tired of this sad state
 260 of affairs and decided to
 261 <a href="https://github.com/petterreinholdtsen/kodi-invidious-plugin">have
 262 a go at improving the Invidious add-on</a>.  As
 263 <a href="https://github.com/iv-org/invidious/issues/3872">Google has
 264 already attacked</a> the Invidious concept, so it need all the support
 265 if can get.  My small contribution here is to improve the service
 266 status on Kodi.</p>
 267
 268 <p>I added support to the Invidious add-on for automatically picking a
 269 working Invidious instance, instead of requiring the user to specify
 270 the URL to a specific instance after installation.  I also had a look
 271 at the set of patches floating around in the various forks on github,
 272 and decided to clean up at least some of the features I liked and
 273 integrate them into my new release branch.  Now the plugin can handle
 274 channel and short video items in search results.  Earlier it could
 275 only handle single video instances in the search response.  I also
 276 brushed up the set of metadata displayed a bit, but hope I can figure
 277 out how to get more relevant metadata displayed.</p>
 278
 279 <p>Because I only use Kodi 20 myself, I only test on version 20 and am
 280 only motivated to ensure version 20 is working.  Because of API changes
 281 between version 19 and 20, I suspect it will fail with earlier Kodi
 282 versions.</p>
 283
 284 <p>I already
 285 <a href="https://github.com/xbmc/repo-plugins/pull/4363">asked to have
 286 the add-on added</a> to the official Kodi 20 repository, and is
 287 waiting to heard back from the repo maintainers.</p>

 306       <div class="body"><p>With yesterdays
 307 <a href="https://www.debian.org/News/2023/20230610">release of Debian
 308 12 Bookworm</a>, I am happy to know the
 309 <a href="https://tracker.debian.org/pkg/opensnitch">the interactive
 310 application firewall OpenSnitch</a> is available for a wider audience.
 311 I have been running it for a few weeks now, and have been surprised
 312 about some of the programs connecting to the Internet.  Some programs
 313 are obviously calling out from my machine, like the NTP network based
 314 clock adjusting system and Tor to reach other Tor clients, but others
 315 were more dubious.  For example, the KDE Window manager try to look up
 316 the host name in DNS, for no apparent reason, but if this lookup is
 317 blocked the KDE desktop get periodically stuck when I use it.  Another
 318 surprise was how much Firefox call home directly to mozilla.com,
 319 mozilla.net and googleapis.com, to mention a few, when I visit other
 320 web pages.  This direct connection happen even if I told Firefox to
 321 always use a proxy, and the proxy setting is ignored for this traffic.
 322 Other surprising connections come from audacity and dirmngr (I do not
 323 use Gnome).  It took some trial and error to get a good default set of
 324 permissions.  Without it, I would get popups asking for permissions at
 325 any time, also the most inconvenient ones where I am in the middle of
 326 a time sensitive gaming session.</p>
 327
 328 <p>I suspect some application developers should rethink when then need
 329 to use network connections or DNS lookups, and recommend testing
 330 OpenSnitch (only <tt>apt install opensnitch</tt> away in Debian
 331 Bookworm) to locate and report any surprising Internet connections on
 332 your desktop machine.</p>
 333
 334 <p>At the moment the upstream developer and Debian package maintainer
 335 is working on making the system more reliable in Debian, by enabling
 336 the eBPF kernel module to track processes and connections instead of
 337 depending in content in /proc/.  This should enter unstable fairly
 338 soon.</p>

 367 (EN 13757-2, EN 13757-3 and EN 13757–4)</a> provide a cross vendor way
 368 to talk to and collect meter data.  I ran into this standard when I
 369 wanted to monitor some heat distribution meters, and managed to find
 370 free software that could do the job.  The meters in question broadcast
 371 encrypted messages with meter information via radio, and the hardest
 372 part was to track down the encryption keys from the vendor.  With this
 373 in place I could set up a MQTT gateway to submit the meter data for
 374 graphing.</p>
 375
 376 <p>The free software systems in question,
 377 <a href="https://tracker.debian.org/pkg/rtl-wmbus">rtl-wmbus</a> to
 378 read the messages from a software defined radio, and
 379 <a href="https://tracker.debian.org/pkg/wmbusmeters">wmbusmeters</a> to
 380 decrypt and decode the content of the messages, is working very well
 381 and allowe me to get frequent updates from my meters.  I got in touch
 382 with upstream last year to see if there was any interest in publishing
 383 the packages via Debian.  I was very happy to learn that Fredrik
 384 Öhrström volunteered to maintain the packages, and I have since
 385 assisted him in getting Debian package build rules in place as well as
 386 sponsoring the packages into the Debian archive.  Sadly we completed
 387 it too late for them to become part of the next stable Debian release
 388 (Bookworm).  The wmbusmeters package just cleared the NEW queue.  It
 389 will need some work to fix a built problem, but I expect Fredrik will
 390 find a solution soon.</p>
 391
 392 <p>If you got a infrastructure meter supporting the Meter Bus
 393 standard, I strongly recommend having a look at these nice
 394 packages.</p>

 412       <div class="date">14th May 2023</div>
 413       <div class="body"><p>The LinuxCNC project is making headway these days.  A lot of
 414 patches and issues have seen activity on
 415 <a href="https://github.com/LinuxCNC/linuxcnc/">the project github
 416 pages</a> recently.  A few weeks ago there was a developer gathering
 417 over at the <a href="https://tormach.com/">Tormach</a> headquarter in
 418 Wisconsin, and now we are planning a new gathering in Norway.  If you
 419 wonder what LinuxCNC is, lets quote Wikipedia:</p>
 420
 421 <blockquote>
 422 "LinuxCNC is a software system for numerical control of
 423 machines such as milling machines, lathes, plasma cutters, routers,
 424 cutting machines, robots and hexapods. It can control up to 9 axes or
 425 joints of a CNC machine using G-code (RS-274NGC) as input. It has
 426 several GUIs suited to specific kinds of usage (touch screen,
 427 interactive development)."
 428 </blockquote>
 429
 430 <p>The Norwegian developer gathering take place the weekend June 16th
 431 to 18th this year, and is open for everyone interested in contributing
 432 to LinuxCNC.  Up to date information about the gathering can be found
 433 in
 434 <a href="https://sourceforge.net/p/emc/mailman/emc-developers/thread/sa64jp06nob.fsf%40hjemme.reinholdtsen.name/#msg37837251">the
 435 developer mailing list thread</a> where the gathering was announced.
 436 Thanks to the good people at
 437 <a href="https://www.debian.org/">Debian</a>,
 438 <a href="https://www.redpill-linpro.com/">Redpill-Linpro</a> and

 460       <div class="date">13th May 2023</div>
 461       <div class="body"><p>A bit delayed,
 462 <a href="https://tracker.debian.org/pkg/opensnitch">the interactive
 463 application firewall OpenSnitch</a> package in Debian now got the
 464 latest fixes ready for Debian Bookworm.  Because it depend on a
 465 package missing on some architectures, the autopkgtest check of the
 466 testing migration script did not understand that the tests were
 467 actually working, so the migration was delayed.  A bug in the package
 468 dependencies is also fixed, so those installing the firewall package
 469 (opensnitch) now also get the GUI admin tool (python3-opensnitch-ui)
 470 installed by default.  I am very grateful to Gustavo Iñiguez Goya for
 471 his work on getting the package ready for Debian Bookworm.</p>
 472
 473 <p>Armed with this package I have discovered some surprising
 474 connections from programs I believed were able to work completly
 475 offline, and it has already proven its worth, at least to me.  If you
 476 too want to get more familiar with the kind of programs using
 477 Internett connections on your machine, I recommend testing <tt>apt
 478 install opensnitch</tt> in Bookworm and see what you think.</p>
 479
 480 <p>The package is still not able to build its eBPF module within
 481 Debian.  Not sure how much work it would be to get it working, but
 482 suspect some kernel related packages need to be extended with more
 483 header files to get it working.</p>

 501       <div class="date">23rd April 2023</div>
 502       <div class="body"><p>While visiting a convention during Easter, it occurred to me that
 503 it would be great if I could have a digital Dictaphone with
 504 transcribing capabilities, providing me with texts to cut-n-paste into
 505 stuff I need to write.  The background is that long drives often bring
 506 up the urge to write on texts I am working on, which of course is out
 507 of the question while driving.  With the release of
 508 <a href="https://github.com/openai/whisper/">OpenAI Whisper</a>, this
 509 seem to be within reach with Free Software, so I decided to give it a
 510 go.  OpenAI Whisper is a Linux based neural network system to read in
 511 audio files and provide text representation of the speech in that
 512 audio recording.  It handle multiple languages and according to its
 513 creators even can translate into a different language than the spoken
 514 one.  I have not tested the latter feature.  It can either use the CPU
 515 or a GPU with CUDA support.  As far as I can tell, CUDA in practice
 516 limit that feature to NVidia graphics cards.  I have few of those, as
 517 they do not work great with free software drivers, and have not tested
 518 the GPU option.  While looking into the matter, I did discover some
 519 work to provide CUDA support on non-NVidia GPUs, and some work with
 520 the library used by Whisper to port it to other GPUs, but have not
 521 spent much time looking into GPU support yet.  I've so far used an old
 522 X220 laptop as my test machine, and only transcribed using its
 523 CPU.</p>
 524
 525 <p>As it from a privacy standpoint is unthinkable to use computers
 526 under control of someone else (aka a "cloud" service) to transcribe
 527 ones thoughts and personal notes, I want to run the transcribing
 528 system locally on my own computers.  The only sensible approach to me
 529 is to make the effort I put into this available for any Linux user and
 530 to upload the needed packages into Debian.  Looking at Debian Bookworm, I
 531 discovered that only three packages were missing,
 532 <a href="https://bugs.debian.org/1034307">tiktoken</a>,
 533 <a href="https://bugs.debian.org/1034144">triton</a>, and
 534 <a href="https://bugs.debian.org/1034091">openai-whisper</a>.  For a while
 535 I also believed
 536 <a href="https://bugs.debian.org/1034286">ffmpeg-python</a> was
 537 needed, but as its
 538 <a href="https://github.com/kkroening/ffmpeg-python/issues/760">upstream
 539 seem to have vanished</a> I found it safer
 540 <a href="https://github.com/openai/whisper/pull/1242">to rewrite
 541 whisper</a> to stop depending on in than to introduce ffmpeg-python
 542 into Debian.  I decided to place these packages under the umbrella of
 543 <a href="https://salsa.debian.org/deeplearning-team">the Debian Deep
 544 Learning Team</a>, which seem like the best team to look after such
 545 packages.  Discussing the topic within the group also made me aware
 546 that the triton package was already a future dependency of newer
 547 versions of the torch package being planned, and would be needed after
 548 Bookworm is released.</p>
 549
 550 <p>All required code packages have been now waiting in
 551 <a href="https://ftp-master.debian.org/new.html">the Debian NEW
 552 queue</a> since Wednesday, heading for Debian Experimental until
 553 Bookworm is released.  An unsolved issue is how to handle the neural
 554 network models used by Whisper.  The default behaviour of Whisper is
 555 to require Internet connectivity and download the model requested to
 556 <tt>~/.cache/whisper/</tt> on first invocation.  This obviously would
 557 fail <a href="https://people.debian.org/~bap/dfsg-faq.html">the
 558 deserted island test of free software</a> as the Debian packages would
 559 be unusable for someone stranded with only the Debian archive and solar
 560 powered computer on a deserted island.</p>
 561
 562 <p>Because of this, I would love to include the models in the Debian
 563 mirror system.  This is problematic, as the models are very large
 564 files, which would put a heavy strain on the Debian mirror
 565 infrastructure around the globe.  The strain would be even higher if
 566 the models change often, which luckily as far as I can tell they do
 567 not.  The small model, which according to its creator is most useful
 568 for English and in my experience is not doing a great job there
 569 either, is 462 MiB (deb is 414 MiB).  The medium model, which to me
 570 seem to handle English speech fairly well is 1.5 GiB (deb is 1.3 GiB)
 571 and the large model is 2.9 GiB (deb is 2.6 GiB).  I would assume
 572 everyone with enough resources would prefer to use the large model for
 573 highest quality.  I believe the models themselves would have to go
 574 into the non-free part of the Debian archive, as they are not really
 575 including any useful source code for updating the models.  The
 576 "source", aka the model training set, according to the creators
 577 consist of "680,000 hours of multilingual and multitask supervised
 578 data collected from the web", which to me reads material with both
 579 unknown copyright terms, unavailable to the general public.  In other
 580 words, the source is not available according to the Debian Free
 581 Software Guidelines and the model should be considered non-free.</p>
 582
 583 <p>I asked the Debian FTP masters for advice regarding uploading a
 584 model package on their IRC channel, and based on the feedback there it
 585 is still unclear to me if such package would be accepted into the
 586 archive.  In any case I wrote build rules for a
 587 <a href="https://salsa.debian.org/deeplearning-team/openai-whisper-model">OpenAI
 588 Whisper model package</a> and
 589 <a href="https://github.com/openai/whisper/pull/1257">modified the
 590 Whisper code base</a> to prefer shared files under <tt>/usr/</tt> and
 591 <tt>/var/</tt> over user specific files in <tt>~/.cache/whisper/</tt>
 592 to be able to use these model packages, to prepare for such
 593 possibility.  One solution might be to include only one of the models
 594 (small or medium, I guess) in the Debian archive, and ask people to
 595 download the others from the Internet.  Not quite sure what to do
 596 here, and advice is most welcome (use the debian-ai mailing list).</p>
 597
 598 <p>To make it easier to test the new packages while I wait for them to
 599 clear the NEW queue, I created an APT source targeting bookworm.  I
 600 selected Bookworm instead of Bullseye, even though I know the latter
 601 would reach more users, is that some of the required dependencies are
 602 missing from Bullseye and I during this phase of testing did not want
 603 to backport a lot of packages just to get up and running.</p>
 604
 605 <p>Here is a recipe to run as user root if you want to test OpenAI
 606 Whisper using Debian packages on your Debian Bookworm installation,
 607 first adding the APT repository GPG key to the list of trusted keys,
 608 then setting up the APT repository and finally installing the packages
 609 and one of the models:</p>
 610
 611 <p><pre>
 612 curl https://geekbay.nuug.no/~pere/openai-whisper/D78F5C4796F353D211B119E28200D9B589641240.asc \
 613   -o /etc/apt/trusted.gpg.d/pere-whisper.asc
 614 mkdir -p /etc/apt/sources.list.d
 615 cat > /etc/apt/sources.list.d/pere-whisper.list &lt;&lt;EOF
 616 deb https://geekbay.nuug.no/~pere/openai-whisper/ bookworm main
 617 deb-src https://geekbay.nuug.no/~pere/openai-whisper/ bookworm main
 618 EOF
 619 apt update
 620 apt install openai-whisper
 621 </pre></p>
 622
 623 <p>The package work for me, but have not yet been tested on any other
 624 computer than my own.  With it, I have been able to (badly) transcribe
 625 a 2 minute 40 second Norwegian audio clip to test using the small
 626 model.  This took 11 minutes and around 2.2 GiB of RAM.  Transcribing
 627 the same file with the medium model gave a accurate text in 77 minutes
 628 using around 5.2 GiB of RAM.  My test machine had too little memory to
 629 test the large model, which I believe require 11 GiB of RAM.  In
 630 short, this now work for me using Debian packages, and I hope it will
 631 for you and everyone else once the packages enter Debian.</p>
 632
 633 <p>Now I can start on the audio recording part of this project.</p>

 651       <div class="date"> 7th April 2023</div>
 652       <div class="body"><p>Today I finally found time to track down a useful radio frequency
 653 scanner for my software defined radio.  Just for fun I tried to locate
 654 the radios used in the areas, and a good start would be to scan all
 655 the frequencies to see what is in use.  I've tried to find a useful
 656 program earlier, but ran out of time before I managed to find a useful
 657 tool.  This time I was more successful, and after a few false leads I
 658 found a description of
 659 <a href="https://www.kali.org/tools/rtlsdr-scanner/">rtlsdr-scanner
 660 over at the Kali site</a>, and was able to track down
 661 <a href="https://gitlab.com/kalilinux/packages/rtlsdr-scanner.git">the
 662 Kali package git repository</a> to build a deb package for the
 663 scanner.  Sadly the package is missing from the Debian project itself,
 664 at least in Debian Bullseye.  Two runtime dependencies,
 665 <a href="https://gitlab.com/kalilinux/packages/python-visvis.git">python-visvis</a>
 666 and
 667 <a href="https://gitlab.com/kalilinux/packages/python-rtlsdr.git">python-rtlsdr</a>
 668 had to be built and installed separately.  Luckily '<tt>gbp
 669 buildpackage</tt>' handled them just fine and no further packages had
 670 to be manually built.  The end result worked out of the box after
 671 installation.</p>
 672
 673 <p>My initial scans for FM channels worked just fine, so I knew the
 674 scanner was functioning.  But when I tried to scan every frequency
 675 from 100 to 1000 MHz, the program stopped unexpectedly near the
 676 completion.  After some debugging I discovered USB software radio I
 677 used rejected frequencies above 948 MHz, triggering a unreported
 678 exception breaking the scan.  Changing the scan to end at 957 worked
 679 better.  I similarly found the lower limit to be around 15, and ended
 680 up with the following full scan:</p>
 681
 682 <p><a href="https://people.skolelinux.org/pere/blog/images/2023-04-07-radio-freq-scanning.png"><img src="https://people.skolelinux.org/pere/blog/images/2023-04-07-radio-freq-scanning.png" width="100%"></a></p>
 683
 684 <p>Saving the scan did not work, but exporting it as a CSV file worked
 685 just fine.  I ended up with around 477k CVS lines with dB level for
 686 the given frequency.</p>
 687
 688 <p>The save failure seem to be a missing UTF-8 encoding issue in the
 689 python code.  Will see if I can find time to send a patch
 690 <a href="https://github.com/CdeMills/RTLSDR-Scanner/">upstream</a>
 691 later to fix this exception:</p>
