  24       <div class="date">12th November 2023</div>
  25       <div class="body"><p>For a while now I wanted to have direct access to the
  26 <a href="https://signal.org/">Signal</a> database of messages and
  27 channels of my Desktop edition of Signal.  I prefer the enforced end
  28 to end encryption of Signal these days for my communication with
  29 friends and family, to increase the level of safety and privacy as
  30 well as raising the cost of the mass surveillance government and
  31 non-government entities practice these days.  In August I came across
  32 a nice
  33 <a href="https://www.yoranbrondsema.com/post/the-guide-to-extracting-statistics-from-your-signal-conversations/">recipe
  34 on how to use sqlcipher to extract statistics from the Signal
  35 database</a> explaining how to do this.  Unfortunately this did not
  36 work with the version of sqlcipher in Debian.  The
  37 <a href="http://tracker.debian.org/sqlcipher/">sqlcipher</a>
  38 package is a "fork" of the sqlite package with added support for
  39 encrypted databases.  Sadly the current Debian maintainer
  40 <a href="https://bugs.debian.org/961598">announced more than three
  41 years ago that he did not have time to maintain sqlcipher</a>, so it
  42 seemed unlikely to be upgraded by the maintainer.  I was reluctant to
  43 take on the job myself, as I have very limited experience maintaining
  44 shared libraries in Debian.  After waiting and hoping for a few
  45 months, I gave up the last  week, and set out to update the package.  In
  46 the process I orphaned it to make it more obvious for the next person
  47 looking at it that the package need proper maintenance.</p>
  48
  49 <p>The version in Debian was around five years old, and quite a lot of
  50 changes had taken place upstream into the Debian maintenance git
  51 repository.  After spending a few days importing the new upstream
  52 versions, realising that upstream did not care much for SONAME
  53 versioning as I saw library symbols being both added and removed with
  54 minor version number changes to the project, I concluded that I had to
  55 do a SONAME bump of the library package to avoid surprising the
  56 reverse dependencies.  I even added a simple
  57 autopkgtest script to ensure the package work as intended.  Dug deep
  58 into the hole of learning shared library maintenance, I set out a few
  59 days ago to upload the new version to Debian experimental to see what
  60 the quality assurance framework in Debian had to say about the result.
  61 The feedback told me the pacakge was not too shabby, and yesterday I
  62 uploaded the latest version to Debian unstable.  It should enter
  63 testing today or tomorrow, perhaps delayed by
  64 <a href="https://bugs.debian.org/1055812">a small library
  65 transition</a>.</p>
  66
  67 <p>Armed with a new version of sqlcipher, I can now have a look at the
  68 SQL database in ~/.config/Signal/sql/db.sqlite.  First, one need to
  69 fetch the encryption key from the Signal configuration using this
  70 simple JSON extraction command:</p>
  71
  72 <pre>/usr/bin/jq -r '."key"' ~/.config/Signal/config.json</pre>
  73
  74 <p>Assuming the result from that command is 'secretkey', which is a
  75 hexadecimal number representing the key used to encrypt the database.
  76 Next, one can now connect to the database and inject the encryption
  77 key for access via SQL to fetch information from the database.  Here
  78 is an example dumping the database structure:</p>
  79
  80 <pre>
  81 % sqlcipher ~/.config/Signal/sql/db.sqlite
  82 sqlite> PRAGMA key = "x'secretkey'";

 508 today, and decided it was time to move the code base from Subversion
 509 to git and find a new home for it, as the previous one (Debian Alioth)
 510 has been shut down.  I decided to go with
 511 <a href="https://codeberg.org/">Codeberg</a> this time, as it is my git
 512 service of choice these days, did a quick and dirty migration to git
 513 and updated the code with a few patches I found in the Debian bug
 514 tracker.  These are the release notes:</p>
 515
 516 <p>New in 0.17 released 2023-11-10:</p>
 517
 518 <ul>
 519 <li>Moved project to Codeberg, as Alioth is shut down.</li>
 520 <li>Add Solaris support (use &lt;sys/byteorder.h> instead of &lt;byteswap.h>).
 521    Patch from Rainer Orth.</li>
 522 <li>Added missing newline from printf() line.  Patch from Frank Dana.</li>

 546       <div class="date"> 5th November 2023</div>
 547       <div class="body"><p>All the books I have published so far has been using
 548 <a href="https://docbook.org/">DocBook</a> somewhere in the process.
 549 For the first book, the source format was DocBook, while for every
 550 later book it was an intermediate format used as the stepping stone to
 551 be able to present the same manuscript in several formats, on paper,
 552 as ebook in ePub format, as a HTML page and as a PDF file either for
 553 paper production or for Internet consumption.  This is made possible
 554 with a wide variety of free software tools with DocBook support in
 555 Debian.  The source format of later books have been docx via rst,
 556 Markdown, Filemaker and Asciidoc, and for all of these I was able to
 557 generate a suitable DocBook file for further processing using
 558 <a href="https://tracker.debian.org/pkg/pandoc">pandoc</a>,
 559 <a href="https://tracker.debian.org/pkg/asciidoc">a2x</a> and
 560 <a href="https://tracker.debian.org/pkg/asciidoctor">asciidoctor</a>,
 561 as well as rendering using
 562 <a href="https://tracker.debian.org/pkg/xmlto">xmlto</a>,
 563 <a href="https://tracker.debian.org/pkg/dbtoepub">dbtoepub</a>,
 564 <a href="https://tracker.debian.org/pkg/dblatex">dblatex</a>,
 565 <a href="https://tracker.debian.org/pkg/docbook-xsl">docbook-xsl</a> and
 566 <a href="https://tracker.debian.org/pkg/fop">fop</a>.</p>
 567
 568 <p>Most of the <a href="http://www.hungry.com/~pere/publisher/">books I
 569 have published</a> are translated books, with English as the source
 570 language.  The use of
 571 <a href="https://tracker.debian.org/pkg/po4a">po4a</a> to
 572 handle translations using the gettext PO format has been a blessing,
 573 but publishing translated books had triggered the need to ensure the
 574 DocBook tools handle relevant languages correctly.  For every new
 575 language I have published, I had to submit patches dblatex, dbtoepub
 576 and docbook-xsl fixing incorrect language and country specific issues
 577 in the framework themselves.  Typically this has been missing keywords
 578 like 'figure' or sort ordering of index entries.  After a while it
 579 became tiresome to only discover issues like this by accident, and I
 580 decided to write a DocBook "test framework" exercising various
 581 features of DocBook and allowing me to see all features exercised for
 582 a given language.  It consist of a set of DocBook files, a version 4
 583 book, a version 5 book, a v4 book set, a v4 selection of problematic
 584 tables, one v4 testing sidefloat and finally one v4 testing a book of
 585 articles.  The DocBook files are accompanied with a set of build rules
 586 for building PDF using dblatex and docbook-xsl/fop, HTML using xmlto
 587 or docbook-xsl and epub using dbtoepub.  The result is a set of files
 588 visualizing footnotes, indexes, table of content list, figures,
 589 formulas and other DocBook features, allowing for a quick review on
 590 the completeness of the given locale settings.  To build with a
 591 different language setting, all one need to do is edit the lang= value
 592 in the .xml file to pick a different ISO 639 code value and run
 593 'make'.</p>
 594
 595 <p>The <a href="https://codeberg.org/pere/docbook-example/">test framework
 596 source code</a> is available from Codeberg, and a generated set of
 597 presentations of the various examples is available as Codeberg static
 598 web pages at
 599 <a href="https://pere.codeberg.page/docbook-example/">https://pere.codeberg.page/docbook-example/</a>.
 600 Using this test framework I have been able to discover and report
 601 several bugs and missing features in various tools, and got a lot of
 602 them fixed.  For example I got Northern Sami keywords added to both
 603 docbook-xsl and dblatex, fixed several typos in Norwegian bokmål and
 604 Norwegian Nynorsk, support for non-ascii title IDs added to pandoc,
 605 Norwegian index sorting support fixed in xindy and initial Norwegian
 606 Bokmål support added to dblatex.  Some issues still remains, though.
 607 Default index sorting rules are still broken in several tools, so the
 608 Norwegian letters æ, ø and å are more often than not sorted properly
 609 in the book index.</p>
 610
 611 <p>The test framework recently received some more polish, as part of
 612 publishing my latest book.  This book contained a lot of fairly
 613 complex tables, which exposed bugs in some of the tools.  This made me
 614 add a new test file with various tables, as well as spend some time to
 615 brush up the build rules.  My goal is for the test framework to
 616 exercise all DocBook features to make it easier to see which features
 617 work with different processors, and hopefully get them all to support
 618 the full set of DocBook features.  Feel free to send patches to extend
 619 the test set, and test it with your favorite DocBook processor.

 672 <p>I 1979 leverte Ole-Erik Yrvin en hovedfagsoppgave for Cand. Scient.
 673   ved Institutt for sosiologi på Universitetet i Oslo på oppdrag fra
 674   Forbruker- og administrasjonsdepartementet. Oppgaven evaluerte
 675   Angrefristloven fra 1972, og det han oppdaget førte til at loven ble
 676   endret fire år senere.</p>
 677
 678 <p>Jeg har kjent Ole-Erik en stund, og synes det var trist at hans
 679   oppgave ikke lenger er tilgjengelig, hverken fra oppdragsgiver
 680   eller fra universitetet.  Hans forsøk på å få den avbildet og lagt
 681   ut på Internett har vist seg fånyttes, så derfor tilbød jeg meg for
 682   en stund tilbake å publisere den og gjøre den tilgjengelig med
 683   fribruksvilkår på Internett.  Det er nå klart, og hovedfagsoppgaven
 684   er tilgjengelig blant annet via <a
 685   href="http://www.hungry.com/~pere/publisher/">min liste over
 686   publiserte bøker</a>, både som nettside,
 687   <a href="https://www.lulu.com/search?contributor=Ole-Erik+Yrvin">digital
 688   bok i ePub-format og på papir fra lulu.com</a>.  Jeg regner med at
 689   den også vil dukke opp på nettbokhandlere i løpet av en måned eller
 690   to.</p>
 691
 692 <p>Alle tabeller og figurer er gjenskapt for bedre lesbarhet, noen
 693   skrivefeil rettet opp og mange referanser har fått flere detaljer
 694   som ISBN-nummer og DOI-referanse.  Selv om jeg ikke regner med at
 695   dette blir en kioskvelter, så håper jeg denne nye utgaven kan komme
 696   fremtiden til glede.</p>

 716       <div class="date"> 7th September 2023</div>
 717       <div class="body"><p>Medlemmene av Norges regjering har demonstert de siste månedene at
 718 habilitetsvureringer ikke er deres sterke side og det gjelder både
 719 Arbeiderpartiets og Senterpartiers representater. Det er heldigvis
 720 enklere i det private, da inhabilitetsreglene kun gjelder de som
 721 jobber for folket, ikke seg selv.  Sist ut er utenriksminister
 722 Huitfeldt.  I går kom nyheten om at
 723 <a href="https://www.nrk.no/nyheter/riksadvokaten_-okokrim-nestsjef-kan-behandle-huitfeldt-saken-1.16545162">Riksadvokaten
 724 har konkludert med at nestsjefen i Økokrim kan behandle sak om
 725 habilitet og innsidekunnskap</a> for Huitfeldt, på tross av at hans
 726 overordnede, sjefen for Økokrim, har meldt seg inhabil i saken.  Dette
 727 er litt rart.  I veilednigen
 728 «<a href="https://www.regjeringen.no/globalassets/upload/krd/vedlegg/komm/veiledere/habilitet_i_kommuner_og_fylkeskommuner.pdf">Habilitet
 729 i kommuner og fylkeskommuner</a>» av Kommunal- og regionaldepartementet
 730 forteller de hva som gjelder, riktig nok gjelder veiledningen ikke for
 731 Økokrim som jo ikke er kommune eller fylkeskommune, men jeg får ikke
 732 inntrykk av at dette er regler som kun gjelder for kommune og
 733 fylkeskommune:
 734
 735 <blockquote>
 736 <p>«<strong>2.1 Oversikt over inhabilitetsgrunnlagene</strong>
 737
 738 <p>De alminnelige reglene om inhabilitet for den offentlige
 739 forvaltningen er gitt i
 740 <a href="https://lovdata.no/dokument/NL/lov/1967-02-10/KAPITTEL_2#KAPITTEL_2">forvaltningsloven
 741 §§ 6 til 10</a>. Forvaltningslovens hovedregel om inhabilitet framgår
 742 av § 6. Her er det gitt tre ulike grunnlag som kan føre til at en
 743 tjenestemann eller folkevalgt blir inhabil. I § 6 første ledd
 744 bokstavene a til e er det oppstilt konkrete tilknytningsforhold mellom
 745 tjenestemannen og saken eller sakens parter som automatisk fører til
 746 inhabilitet. Annet ledd oppstiller en skjønnsmessig regel om at
 747 tjenestemannen også kan bli inhabil etter en konkret vurdering av
 748 inhabilitetsspørsmålet, der en lang rekke momenter kan være
 749 relevante. I tredje ledd er det regler om såkalt avledet
 750 inhabilitet. Det vil si at en underordnet tjenestemann blir inhabil
 751 fordi en overordnet er inhabil.»</p>
 752 </blockquote>
 753
 754 <p>Loven sier ganske enkelt «Er den overordnede tjenestemann ugild,
 755 kan avgjørelse i saken heller ikke treffes av en direkte underordnet
 756 tjenestemann i samme forvaltningsorgan.»  Jeg antar tanken er at en
 757 underordnet vil stå i fare for å tilpasse sine konklusjoner til det
 758 overordnet vil ha fordel av, for å fortsatt ha et godt forhold til sin
 759 overordnede.  Men jeg er ikke jurist og forstår nok ikke kompliserte
 760 juridiske vurderinger.  For å sitere «Kamerat Napoleon» av George
 761 Orwell: «Alle dyr er like, men noen dyr er likere enn andre».

 793 already attacked</a> the Invidious concept, so it need all the support
 794 if can get.  My small contribution here is to improve the service
 795 status on Kodi.</p>
 796
 797 <p>I added support to the Invidious add-on for automatically picking a
 798 working Invidious instance, instead of requiring the user to specify
 799 the URL to a specific instance after installation.  I also had a look
 800 at the set of patches floating around in the various forks on github,
 801 and decided to clean up at least some of the features I liked and
 802 integrate them into my new release branch.  Now the plugin can handle
 803 channel and short video items in search results.  Earlier it could
 804 only handle single video instances in the search response.  I also
 805 brushed up the set of metadata displayed a bit, but hope I can figure
 806 out how to get more relevant metadata displayed.</p>
 807
 808 <p>Because I only use Kodi 20 myself, I only test on version 20 and am
 809 only motivated to ensure version 20 is working.  Because of API changes
 810 between version 19 and 20, I suspect it will fail with earlier Kodi
 811 versions.</p>
 812
 813 <p>I already
 814 <a href="https://github.com/xbmc/repo-plugins/pull/4363">asked to have
 815 the add-on added</a> to the official Kodi 20 repository, and is
 816 waiting to heard back from the repo maintainers.</p>

 834       <div class="date">11th June 2023</div>
 835       <div class="body"><p>With yesterdays
 836 <a href="https://www.debian.org/News/2023/20230610">release of Debian
 837 12 Bookworm</a>, I am happy to know the
 838 <a href="https://tracker.debian.org/pkg/opensnitch">the interactive
 839 application firewall OpenSnitch</a> is available for a wider audience.
 840 I have been running it for a few weeks now, and have been surprised
 841 about some of the programs connecting to the Internet.  Some programs
 842 are obviously calling out from my machine, like the NTP network based
 843 clock adjusting system and Tor to reach other Tor clients, but others
 844 were more dubious.  For example, the KDE Window manager try to look up
 845 the host name in DNS, for no apparent reason, but if this lookup is
 846 blocked the KDE desktop get periodically stuck when I use it.  Another
 847 surprise was how much Firefox call home directly to mozilla.com,
 848 mozilla.net and googleapis.com, to mention a few, when I visit other
 849 web pages.  This direct connection happen even if I told Firefox to
 850 always use a proxy, and the proxy setting is ignored for this traffic.
 851 Other surprising connections come from audacity and dirmngr (I do not
 852 use Gnome).  It took some trial and error to get a good default set of
 853 permissions.  Without it, I would get popups asking for permissions at
 854 any time, also the most inconvenient ones where I am in the middle of
 855 a time sensitive gaming session.</p>
 856
 857 <p>I suspect some application developers should rethink when then need
 858 to use network connections or DNS lookups, and recommend testing
 859 OpenSnitch (only <tt>apt install opensnitch</tt> away in Debian
 860 Bookworm) to locate and report any surprising Internet connections on
 861 your desktop machine.</p>
 862
 863 <p>At the moment the upstream developer and Debian package maintainer
 864 is working on making the system more reliable in Debian, by enabling
 865 the eBPF kernel module to track processes and connections instead of
 866 depending in content in /proc/.  This should enter unstable fairly
 867 soon.</p>

 872
 873 <p><strong>Update 2023-06-12</strong>: I got a tip about
 874 <a href="https://wiki.debian.org/PrivacyIssues">a list of privacy

 892       <div class="date">19th May 2023</div>
 893       <div class="body"><p>There is a European standard for reading utility meters like water,
 894 gas, electricity or heat distribution meters.  The
 895 <a href="https://en.wikipedia.org/wiki/Meter-Bus">Meter-Bus standard
 896 (EN 13757-2, EN 13757-3 and EN 13757–4)</a> provide a cross vendor way
 897 to talk to and collect meter data.  I ran into this standard when I
 898 wanted to monitor some heat distribution meters, and managed to find
 899 free software that could do the job.  The meters in question broadcast
 900 encrypted messages with meter information via radio, and the hardest
 901 part was to track down the encryption keys from the vendor.  With this
 902 in place I could set up a MQTT gateway to submit the meter data for
 903 graphing.</p>
 904
 905 <p>The free software systems in question,
 906 <a href="https://tracker.debian.org/pkg/rtl-wmbus">rtl-wmbus</a> to
 907 read the messages from a software defined radio, and
 908 <a href="https://tracker.debian.org/pkg/wmbusmeters">wmbusmeters</a> to
 909 decrypt and decode the content of the messages, is working very well
 910 and allowe me to get frequent updates from my meters.  I got in touch
 911 with upstream last year to see if there was any interest in publishing
 912 the packages via Debian.  I was very happy to learn that Fredrik
 913 Öhrström volunteered to maintain the packages, and I have since
 914 assisted him in getting Debian package build rules in place as well as
 915 sponsoring the packages into the Debian archive.  Sadly we completed
 916 it too late for them to become part of the next stable Debian release
 917 (Bookworm).  The wmbusmeters package just cleared the NEW queue.  It
 918 will need some work to fix a built problem, but I expect Fredrik will
 919 find a solution soon.</p>
 920
 921 <p>If you got a infrastructure meter supporting the Meter Bus
 922 standard, I strongly recommend having a look at these nice
 923 packages.</p>

 941       <div class="date">14th May 2023</div>
 942       <div class="body"><p>The LinuxCNC project is making headway these days.  A lot of
 943 patches and issues have seen activity on
 944 <a href="https://github.com/LinuxCNC/linuxcnc/">the project github
 945 pages</a> recently.  A few weeks ago there was a developer gathering
 946 over at the <a href="https://tormach.com/">Tormach</a> headquarter in
 947 Wisconsin, and now we are planning a new gathering in Norway.  If you
 948 wonder what LinuxCNC is, lets quote Wikipedia:</p>
 949
 950 <blockquote>
 951 "LinuxCNC is a software system for numerical control of
 952 machines such as milling machines, lathes, plasma cutters, routers,
 953 cutting machines, robots and hexapods. It can control up to 9 axes or
 954 joints of a CNC machine using G-code (RS-274NGC) as input. It has
 955 several GUIs suited to specific kinds of usage (touch screen,
 956 interactive development)."
 957 </blockquote>
 958
 959 <p>The Norwegian developer gathering take place the weekend June 16th
 960 to 18th this year, and is open for everyone interested in contributing
 961 to LinuxCNC.  Up to date information about the gathering can be found
 962 in
 963 <a href="https://sourceforge.net/p/emc/mailman/emc-developers/thread/sa64jp06nob.fsf%40hjemme.reinholdtsen.name/#msg37837251">the
 964 developer mailing list thread</a> where the gathering was announced.
 965 Thanks to the good people at

 990       <div class="body"><p>A bit delayed,
 991 <a href="https://tracker.debian.org/pkg/opensnitch">the interactive
 992 application firewall OpenSnitch</a> package in Debian now got the
 993 latest fixes ready for Debian Bookworm.  Because it depend on a
 994 package missing on some architectures, the autopkgtest check of the
 995 testing migration script did not understand that the tests were
 996 actually working, so the migration was delayed.  A bug in the package
 997 dependencies is also fixed, so those installing the firewall package
 998 (opensnitch) now also get the GUI admin tool (python3-opensnitch-ui)
 999 installed by default.  I am very grateful to Gustavo Iñiguez Goya for
1000 his work on getting the package ready for Debian Bookworm.</p>
1001
1002 <p>Armed with this package I have discovered some surprising
1003 connections from programs I believed were able to work completly
1004 offline, and it has already proven its worth, at least to me.  If you
1005 too want to get more familiar with the kind of programs using
1006 Internett connections on your machine, I recommend testing <tt>apt
1007 install opensnitch</tt> in Bookworm and see what you think.</p>
1008
1009 <p>The package is still not able to build its eBPF module within
1010 Debian.  Not sure how much work it would be to get it working, but
1011 suspect some kernel related packages need to be extended with more
1012 header files to get it working.</p>
