+ <div class="date">12th December 2014</div>
+ <div class="body"><p>For noen dager siden
+<a href="http://www.nb.no/Hva-skjer/Aktuelt/Nyheter/Tapt-filmskatt-fra-Disney-funnet-i-Nasjonalbiblioteket">annonserte
+Nasjonalbiblioteket gladnyheten</a> om at de i sine arkiver hadde
+funnet et nitratfilm-eksemplar av en 87 år gammel Disney-film ved navn
+Empty Socks, en film som tidligere var antatt tapt og der det i følge
+nyhetsmeldinger var kun ca. 25 sekunder bevart for ettertiden.
+Nasjonalbiblioteket hadde 5 minutter og 30 sekunder av filmen i sitt
+magasin. Dette er flott for bevaringen av verdens kulturarv. 5,5
+minutter mindre tapt enn vi trodde av får felles historie.</p>
+
+<p>Men hvordan kunne filmen gå tapt, når arkivlovene i USA krevde at
+publiserte filmer på den tiden ble deponert i bibliotek? Forklaringen
+har jeg fra Lawrence Lessig og boken
+<a href="http://free-culture.cc/">Free Culture</a>, som jeg holder på
+<a href="https://github.com/petterreinholdtsen/free-culture-lessig">å
+oversette til norsk</a>:</p>
+
+<p><blockquote>
+<p>Dette er delvis på grunn av loven. Opphavsrettseiere var tidlig i
+ amerikansk opphavsrettslov nødt til å deponere kopier av sine verk i
+ biblioteker. Disse kopiene skulle både sikre spredning av kunnskap,
+ og sikre at det fantes en kopi av verket tilgjengelig når vernetiden
+ utløp, slik at andre kunne få tilgang til og kopiere verket.</p>
+
+<p>Disse reglene gjaldt også for filmer. Men i 1915 gjorde
+ kongressbiblioteket et unntak for film. Filmer kunne bli
+ opphavsrettsbeskyttet så lenge det ble gjort slik deponering. Men
+ filmskaperne fikk så lov til å låne tilbake de deponerte filmene -
+ så lenge de ville uten noe kostnad. Bare i 1915 var det mer enn 5475
+ filmer deponert og “lånt tilbake”. Dermed var det ikke noe eksemplar
+ i noe bibliotek når vernetiden til filmen utløp. Eksemplaret
+ eksisterer - hvis den finnes i det hele tatt - i arkivbiblioteket
+ til filmselskapet.</p>
+</blockquote></p>
+
+<p>Nyheten gjorde meg nysgjerrig på om filmen kunne være falt i det
+fri. En 87 år gammel film kunne jo tenkes å ha blitt en del av
+allemannseiet, slik at vi alle kan bruke den til å bygge videre på vår
+felles kultur uten å måtte be om tillatelse - slik Walt Disney gjorde
+det i starten av sin karriere. Jeg spurte nasjonalbiblioteket, og de
+sa nei. Hvordan kan det ha seg med en så gammel film? Jeg besteme
+meg for å undersøke nærmere. En kan finne informasjon om den norske
+vernetiden på
+<a href="https://lovdata.no/dokument/NL/lov/1961-05-12-2">Lovdata</a>
+og </a>Wikipedia</A>. Her er et relevant <a
+href="https://no.wikipedia.org/wiki/Opphavsrett#Vernetid">utsnitt fra
+siden om opphavsrett i den norske Wikipedia</a>:</p>
+
+<p><blockquote>
+ Ifølge åndsverkloven §§ 40-41 utløper vernetiden for et åndsverk 70
+ år etter utløpet av opphavspersonens dødsår. [...] For filmverk
+ gjelder særlige regler: Her kommer ikke alle mulige opphavspersoner
+ i betraktning, men kun hovedregissøren, manusforfatteren,
+ dialogforfatteren og komponisten av filmmusikken. Vernetiden
+ begynner å løpe etter utgangen av dødsåret til den lengstlevende av
+ disse. [...] Der opphavspersonen er ukjent, utløper opphavsretten 70
+ år etter første kjente offentliggjørelse av verket. Det er kun de
+ økonomiske rettighetene som faller bort i det vernetiden er
+ utløpt. De ideelle rettighetene må fortsatt respekteres, noe som
+ blant annet innebærer at man plikter å navngi opphavspersonen ved
+ tilgjengeliggjøring.

+
+<p>Alle fødsels- og dødsdatoene er fra engelske Wikipedia. Det er
+ikke oppgitt navn på manusforfatter, dialogforfatter og komponist, men
+jeg mistenker at tegnerne vil få opphavsrettigheter på tegnefilmer her
+i Norge, og tar derfor med disse. Kameramannen vil ikke få noen
+rettigheter så vidt jeg forstår, og er derfor ignorert her.</p>
+
+<p>Slik jeg forstår den norske opphavsretten vil dermed dette
+filmverket bli allemannseie (også kalt å falle i det fri) i 2053, 126
+år etter at det ble utgitt. Hvis kun regissørens rettigheter er
+relevante, vil det skje i 2037, 110 år etter at det ble utgitt. Etter
+det vil enhver kunne dele det med alle de har lyst til, fremføre det
+offentlig eller klippe og lime i det for å lage sin egen film basert
+på det - helt uten å måtte spørre noen om lov.</p>
+
+<p>Måtte så Nasjonalbiblioteket spørre om lov før de kunne kopiere
+sitt nitrat-eksemplar over på mer varig format? Nei, heldigvis.
+Åndsverklovens § 16 sier at arkiv, bibliotek, museer og undervisnings-
+og forskningsinstitusjoner har rett til å fremstille eksemplar av verk
+for konserverings- og sikringsformål og andre særskilte formål.</p>

+ <div class="date">22nd November 2014</div>
+ <div class="body"><p>By now, it is well known that Debian Jessie will not be using
+sysvinit as its boot system by default. But how can one keep using
+sysvinit in Jessie? It is fairly easy, and here are a few recipes,
+courtesy of
+<a href="http://www.vitavonni.de/blog/201410/2014102101-avoiding-systemd.html">Erich
+Schubert</a> and
+<a href="http://smcv.pseudorandom.co.uk/2014/still_universal/">Simon
+McVittie</a>.
+
+<p>If you already are using Wheezy and want to upgrade to Jessie and
+keep sysvinit as your boot system, create a file
+<tt>/etc/apt/preferences.d/use-sysvinit</tt> with this content before
+you upgrade:</p>
+
+<p><blockquote><pre>
+Package: systemd-sysv
+Pin: release o=Debian
+Pin-Priority: -1
+</pre></blockquote><p>
+
+<p>This file content will tell apt and aptitude to not consider
+installing systemd-sysv as part of any installation and upgrade
+solution when resolving dependencies, and thus tell it to avoid
+systemd as a default boot system. The end result should be that the
+upgraded system keep using sysvinit.</p>
+
+<p>If you are installing Jessie for the first time, there is no way to
+get sysvinit installed by default (debootstrap used by
+debian-installer have no option for this), but one can tell the
+installer to switch to sysvinit before the first boot. Either by
+using a kernel argument to the installer, or by adding a line to the
+preseed file used. First, the kernel command line argument:
+
+<p><blockquote><pre>
+preseed/late_command="in-target apt-get install --purge -y sysvinit-core"
+</pre></blockquote><p>
+
+<p>Next, the line to use in a preseed file:</p>
+
+<p><blockquote><pre>
+d-i preseed/late_command string in-target apt-get install -y sysvinit-core
+</pre></blockquote><p>
+
+<p>One can of course also do this after the first boot by installing
+the sysvinit-core package.</p>
+
+<p>I recommend only using sysvinit if you really need it, as the
+sysvinit boot sequence in Debian have several hardware specific bugs
+on Linux caused by the fact that it is unpredictable when hardware
+devices show up during boot. But on the other hand, the new default
+boot system still have a few rough edges I hope will be fixed before
+Jessie is released.</p>

+ <div class="date">16th November 2014</div>
+ <div class="body"><p>For en stund tilbake spurte jeg Fornyingsdepartementet om hvilke
+juridiske vurderinger rundt patentproblemstillingen som var gjort da
+H.264 ble tatt inn i <a href="http://standard.difi.no/">statens
+referansekatalog over standarder</a>. Stig Hornnes i FAD tipset meg
+om følgende som står i oppsumeringen til høringen om
+referansekatalogen versjon 2.0, som jeg siden ved hjelp av en
+innsynsforespørsel fikk tak i
+<a href="http://wiki.nuug.no/uttalelser/200901-standardkatalog-v2?action=AttachFile&do=get&target=kongelig-resolusjon.pdf">PDF-utgaven av</a>
+datert 2009-06-03 (saksnummer 200803291, saksbehandler Henrik
+Linnestad).</p>
+
+<p>Der står det følgende om problemstillingen:</p>
+
+<p><blockquote>
+<strong>4.4 Patentproblematikk</strong>
+
+<p>NUUG og Opera ser det som særlig viktig at forslagene knyttet til
+lyd og video baserer seg på de royalty-frie standardene Vorbis, Theora
+og FLAC.</p>
+
+<p>Kommentarene relaterer seg til at enkelte standarder er åpne, men
+inneholder tekniske prosedyrer som det i USA (og noen andre land som
+Japan) er gitt patentrettigheter til. I vårt tilfelle berører dette
+spesielt standardene Mp3 og H.264, selv om Politidirektoratet peker på
+at det muligens kan være tilsvarende problematikk også for Theora og
+Vorbis. Dette medfører at det i USA kan kreves royalties for bruk av
+tekniske løsninger knyttet til standardene, et krav som også
+håndheves. Patenter kan imidlertid bare hevdes i de landene hvor
+patentet er gitt, så amerikanske patenter gjelder ikke andre steder
+enn USA.</p>
+
+<p>Spesielt for utvikling av fri programvare er patenter
+problematisk. GPL, en "grunnleggende" lisens for distribusjon av fri
+programvare, avviser at programvare kan distribueres under denne
+lisensen hvis det inneholder referanser til patenterte rutiner som
+utløser krav om royalties. Det er imidlertid uproblematisk å
+distribuere fri programvareløsninger under GPL som benytter de
+aktuelle standardene innen eller mellom land som ikke anerkjenner
+patentene. Derfor finner vi også flere implementeringer av Mp3 og
+H.264 som er fri programvare, lisensiert under GPL.</p>
+
+<p>I Norge og EU er patentlovgivningen langt mer restriktiv enn i USA,
+men det er også her mulig å få patentert metoder for løsning av et
+problem som relaterer seg til databehandling. Det er AIF bekjent ikke
+relevante patenter i EU eller Norge hva gjelder H.264 og Mp3, men
+muligheten for at det finnes patenter uten at det er gjort krav om
+royalties eller at det senere vil gis slike patenter kan ikke helt
+avvises.</p>
+
+<p>AIF mener det er et behov for å gi offentlige virksomheter mulighet
+til å benytte antatt royaltyfrie åpne standarder som et likeverdig
+alternativ eller i tillegg til de markedsledende åpne standardene.</p>
+
+</blockquote></p>
+
+<p>Det ser dermed ikke ut til at de har vurdert patentspørsmålet i
+sammenheng med opphavsrettsvilkår slik de er formulert for f.eks.
+Apple Final Cut Pro, Adobe Premiere Pro, Avid og Sorenson-verktøyene,
+der det kreves brukstillatelse for patenter som ikke er gyldige i
+Norge for å bruke disse verktøyene til annet en personlig og ikke
+kommersiell aktivitet når det gjelder H.264-video. Jeg må nok lete
+videre etter svar på det spørsmålet.</p>

+ <div class="date">10th November 2014</div>
+ <div class="body"><p>The right to communicate with your friends and family in private,
+without anyone snooping, is a right every citicen have in a liberal
+democracy. But this right is under serious attack these days.</p>
+
+<p>A while back it occurred to me that one way to make the dragnet
+surveillance conducted by NSA, GCHQ, FRA and others (and confirmed by
+the whisleblower Snowden) more expensive for Internet email,
+is to deliver all email using SMTP via Tor. Such SMTP option would be
+a nice addition to the FreedomBox project if we could send email
+between FreedomBox machines without leaking metadata about the emails
+to the people peeking on the wire. I
+<a href="http://lists.alioth.debian.org/pipermail/freedombox-discuss/2014-October/006493.html">proposed
+this on the FreedomBox project mailing list in October</a> and got a
+lot of useful feedback and suggestions. It also became obvious to me
+that this was not a novel idea, as the same idea was tested and
+documented by Johannes Berg as early as 2006, and both
+<a href="https://github.com/pagekite/Mailpile/wiki/SMTorP">the
+Mailpile</a> and <a href="http://dee.su/cables">the Cables</a> systems
+propose a similar method / protocol to pass emails between users.</p>
+
+<p>To implement such system one need to set up a Tor hidden service
+providing the SMTP protocol on port 25, and use email addresses
+looking like username@hidden-service-name.onion. With such addresses
+the connections to port 25 on hidden-service-name.onion using Tor will
+go to the correct SMTP server. To do this, one need to configure the
+Tor daemon to provide the hidden service and the mail server to accept
+emails for this .onion domain. To learn more about Exim configuration
+in Debian and test the design provided by Johannes Berg in his FAQ, I
+set out yesterday to create a Debian package for making it trivial to
+set up such SMTP over Tor service based on Debian. Getting it to work
+were fairly easy, and
+<a href="https://github.com/petterreinholdtsen/exim4-smtorp">the
+source code for the Debian package</a> is available from github. I
+plan to move it into Debian if further testing prove this to be a
+useful approach.</p>
+
+<p>If you want to test this, set up a blank Debian machine without any
+mail system installed (or run <tt>apt-get purge exim4-config</tt> to
+get rid of exim4). Install tor, clone the git repository mentioned
+above, build the deb and install it on the machine. Next, run
+<tt>/usr/lib/exim4-smtorp/setup-exim-hidden-service</tt> and follow
+the instructions to get the service up and running. Restart tor and
+exim when it is done, and test mail delivery using swaks like
+this:</p>
+
+<p><blockquote><pre>
+torsocks swaks --server dutlqrrmjhtfa3vp.onion \
+ --to fbx@dutlqrrmjhtfa3vp.onion
+</pre></blockquote></p>
+
+<p>This will test the SMTP delivery using tor. Replace the email
+address with your own address to test your server. :)</p>
+
+<p>The setup procedure is still to complex, and I hope it can be made
+easier and more automatic. Especially the tor setup need more work.
+Also, the package include a tor-smtp tool written in C, but its task
+should probably be rewritten in some script language to make the deb
+architecture independent. It would probably also make the code easier
+to review. The tor-smtp tool currently need to listen on a socket for
+exim to talk to it and is started using xinetd. It would be better if
+no daemon and no socket is needed. I suspect it is possible to get
+exim to run a command line tool for delivery instead of talking to a
+socket, and hope to figure out how in a future version of this
+system.</p>
+
+<p>Until I wipe my test machine, I can be reached using the
+<tt>fbx@dutlqrrmjhtfa3vp.onion</tt> mail address, deliverable over
+SMTorP. :)</p>

+About Debian Edu and Skolelinux
+===============================
+
+Debian Edu, also known as Skolelinux[2], is a Linux distribution based
+on Debian providing an out-of-the box environment of a completely
+configured school network. Immediately after installation a school
+server running all services needed for a school network is set up just
+waiting for users and machines being added via GOsa², a comfortable
+Web-UI. A netbooting environment is prepared using PXE, so after
+initial installation of the main server from CD or USB stick all other
+machines can be installed via the network. The provided school server
+provides LDAP database and Kerberos authentication service,
+centralized home directories, DHCP server, web proxy and many other
+services. The desktop contains more than 60 educational software
+packages[3] and more are available from the Debian archive, and
+schools can choose between KDE, Gnome, LXDE, Xfce and MATE desktop
+environment.

+Documentation and translation updates
+-------------------------------------
+
+ * The Debian Edu Jessie Manual is fully translated to German, French,
+ Italian, Danish and Dutch. Partly translated versions exist for
+ Norwegian Bokmal and Spanish.
+
+Other changes
+-------------
+
+ * Due to new Squid settings, powering off or rebooting the main
+ server takes more time.
+ * To manage printers localhost:631 has to be used, currently www:631
+ doesn't work.
+
+Regressions / known problems
+----------------------------
+
+ * Installing LTSP chroot fails with a bug related to eatmydata about
+ exim4-config failing to run its postinst (see Debian bug #765694
+ and Debian bug #762103).
+ * Munin collection is not properly configured on clients (Debian bug
+ #764594). The fix is available in a newer version of munin-node.
+ * PXE setup for Main Server and Thin Client Server setup does not
+ work when installing on a machine without direct Internet access.
+ Will be fixed when Debian bug #766960 is fixed in Jessie.

- <div class="date">26th September 2014</div>
- <div class="body"><p>The <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux
-project</a> provide a Linux solution for schools, including a
-powerful desktop with education software, a central server providing
-web pages, user database, user home directories, central login and PXE
-boot of both clients without disk and the installation to install Debian
-Edu on machines with disk (and a few other services perhaps to small
-to mention here). We in the Debian Edu team are currently working on
-the Jessie based version, trying to get everything in shape before the
-freeze, to avoid having to maintain our own package repository in the
-future. The
-<a href="https://wiki.debian.org/DebianEdu/Status/Jessie">current
-status</a> can be seen on the Debian wiki, and there is still heaps of
-work left. Some fatal problems block testing, breaking the installer,
-but it is possible to work around these to get anyway. Here is a
-recipe on how to get the installation limping along.</p>
-
-<p>First, download the test ISO via
-<a href="ftp://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso">ftp</a>,
-<a href="http://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso">http</a>
-or rsync (use
-ftp.skolelinux.org::cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso).
-The ISO build was broken on Tuesday, so we do not get a new ISO every
-12 hours or so, but thankfully the ISO we already got we are able to
-install with some tweaking.</p>
-
-<p>When you get to the Debian Edu profile question, go to tty2
-(use Alt-Ctrl-F2), run</p>
-
-<p><blockquote><pre>
-nano /usr/bin/edu-eatmydata-install
-</pre></blockquote></p>
-
-<p>and add 'exit 0' as the second line, disabling the eatmydata
-optimization. Return to the installation, select the profile you want
-and continue. Without this change, exim4-config will fail to install
-due to a known bug in eatmydata.</p>
-
-<p>When you get the grub question at the end, answer /dev/sda (or if
-this do not work, figure out what your correct value would be. All my
-test machines need /dev/sda, so I have no advice if it do not fit
-your need.</p>
-
-<p>If you installed a profile including a graphical desktop, log in as
-root after the initial boot from hard drive, and install the
-education-desktop-XXX metapackage. XXX can be kde, gnome, lxde, xfce
-or mate. If you want several desktop options, install more than one
-metapackage. Once this is done, reboot and you should have a working
-graphical login screen. This workaround should no longer be needed
-once the education-tasks package version 1.801 enter testing in two
-days.</p>
-
-<p>I believe the ISO build will start working on two days when the new
-tasksel package enter testing and Steve McIntyre get a chance to
-update the debian-cd git repository. The eatmydata, grub and desktop
-issues are already fixed in unstable and testing, and should show up
-on the ISO as soon as the ISO build start working again. Well the
-eatmydata optimization is really just disabled. The proper fix
-require an upload by the eatmydata maintainer applying the patch
-provided in bug <a href="https://bugs.debian.org/702711">#702711</a>.
-The rest have proper fixes in unstable.</p>
-
-<p>I hope this get you going with the installation testing, as we are
-quickly running out of time trying to get our Jessie based
-installation ready before the distribution freeze in a month.</p>

- <div class="date">25th September 2014</div>
- <div class="body"><p>I use the <a href="https://sourceforge.net/p/lsdvd/">lsdvd tool</a>
-to handle my fairly large DVD collection. It is a nice command line
-tool to get details about a DVD, like title, tracks, track length,
-etc, in XML, Perl or human readable format. But lsdvd have not seen
-any new development since 2006 and had a few irritating bugs affecting
-its use with some DVDs. Upstream seemed to be dead, and in January I
-sent a small probe asking for a version control repository for the
-project, without any reply. But I use it regularly and would like to
-get <a href="https://packages.qa.debian.org/lsdvd">an updated version
-into Debian</a>. So two weeks ago I tried harder to get in touch with
-the project admin, and after getting a reply from him explaining that
-he was no longer interested in the project, I asked if I could take
-over. And yesterday, I became project admin.</p>
-
-<p>I've been in touch with a Gentoo developer and the Debian
-maintainer interested in joining forces to maintain the upstream
-project, and I hope we can get a new release out fairly quickly,
-collecting the patches spread around on the internet into on place.
-I've added the relevant Debian patches to the freshly created git
-repository, and expect the Gentoo patches to make it too. If you got
-a DVD collection and care about command line tools, check out

- <div class="date">21st September 2014</div>
- <div class="body"><p>Rundt omkring i Oslo og Østlandsområdet henger det bokser over
-veiene som jeg har lurt på hva gjør. De har ut fra plassering og
-vinkling sett ut som bokser som sniffer ut et eller annet fra
-forbipasserende trafikk, men det har vært uklart for meg hva det er de
-leser av. Her om dagen tok jeg bilde av en slik boks som henger under
-<a href="http://www.openstreetmap.no/?zoom=19&mlat=59.96396&mlon=10.34443&layers=B00000">ei
-skibru på Sollihøgda</a>:</p>

-
-<p>Boksen er tydelig merket «Kapsch >>>», logoen til
-<a href="http://www.kapsch.net/">det sveitsiske selskapet Kapsch</a> som
-blant annet lager sensorsystemer for veitrafikk. Men de lager mye
-forskjellig, og jeg kjente ikke igjen boksen på utseendet etter en
-kjapp titt på produktlista til selskapet.</p>
-
-<p>I og med at boksen henger over veien E16, en riksvei vedlikeholdt
-av Statens Vegvesen, så antok jeg at det burde være mulig å bruke
-REST-API-et som gir tilgang til vegvesenets database over veier,
-skilter og annet veirelatert til å finne ut hva i alle dager dette
-kunne være. De har både
-<a href="https://www.vegvesen.no/nvdb/api/dokumentasjon/datakatalog">en
-datakatalog</a> og
-<a href="https://www.vegvesen.no/nvdb/api/dokumentasjon/sok">et
-søk</a>, der en kan søke etter ulike typer oppføringer innen for et
-gitt geografisk område. Jeg laget et enkelt shell-script for å hente
-ut antall av en gitt type innenfor området skibrua dekker, og listet
-opp navnet på typene som ble funnet. Orket ikke slå opp hvordan
-URL-koding av aktuelle strenger kunne gjøres mer generisk, og brukte
-en stygg sed-linje i stedet.</p>

-
-<p>Av disse ser ID 775 og 862 mest relevant ut. ID 775 antar jeg
-refererer til fotoboksen som står like ved brua, mens
-«Reisetidsregistreringspunkt» kanskje kan være boksen som henger der.
-Hvordan finner jeg så ut hva dette kan være for noe. En titt på
-<a href="http://labs.vegdata.no/nvdb-datakatalog/862-Reisetidsregistreringspunkt/">datakatalogsiden
-for ID 862/Reisetidsregistreringspunkt</a> viser at det er finnes 53
-slike målere i Norge, og hvor de er plassert, men gir ellers få
-detaljer. Det er plassert 40 på østlandet og 13 i Trondheimsregionen.
-Men siden nevner «AutoPASS», og hvis en slår opp oppføringen på
-Sollihøgda nevner den «Ciber AS» som ID for eksternt system. (Kan det
-være snakk om
-<a href="http://www.proff.no/selskap/ciber-norge-as/oslo/internettdesign-og-programmering/Z0I3KMF4/">Ciber
-Norge AS</a>, et selskap eid av Ciber Europe Bv?) Et nettsøk på
- «Ciber AS autopass» fører meg til en artikkel fra NRK Trøndelag i
- 2013 med tittel
-«<a href="http://www.nrk.no/trondelag/sjekk-dette-hvis-du-vil-unnga-ko-1.11327947">Sjekk
-dette hvis du vil unngå kø</a>». Artikkelen henviser til vegvesenets
-nettside
-<a href="http://www.reisetider.no/reisetid/forside.html">reisetider.no</a>
-som har en
-<a href="http://www.reisetider.no/reisetid/omrade.html?omrade=5">kartside
-for Østlandet</a> som viser at det måles mellom Sandvika og Sollihøgda.
-Det kan dermed se ut til at jeg har funnet ut hva boksene gjør.</p>
-
-<p>Hvis det stemmer, så er dette bokser som leser av AutoPASS-ID-en
-til alle passerende biler med AutoPASS-brikke, og dermed gjør det mulig
-for de som kontrollerer boksene å holde rede på hvor en gitt bil er
-når den passerte et slikt målepunkt. NRK-artikkelen forteller at
-denne informasjonen i dag kun brukes til å koble to
-AutoPASS-brikkepasseringer passeringer sammen for å beregne
-reisetiden, og at bruken er godkjent av Datatilsynet. Det er desverre
-ikke mulig for en sjåfør som passerer under en slik boks å kontrollere
-at AutoPASS-ID-en kun brukes til dette i dag og i fremtiden.</p>
-
-<p>I tillegg til denne type AutoPASS-sniffere vet jeg at det også
-finnes mange automatiske stasjoner som tar betalt pr. passering (aka
-bomstasjoner), og der lagres informasjon om tid, sted og bilnummer i
-10 år. Finnes det andre slike sniffere plassert ut på veiene?</p>
-
-<p>Personlig har jeg valgt å ikke bruke AutoPASS-brikke, for å gjøre
-det vanskeligere og mer kostbart for de som vil invadere privatsfæren
-og holde rede på hvor bilen min beveger seg til enhver tid. Jeg håper
-flere vil gjøre det samme, selv om det gir litt høyere private
-utgifter (dyrere bompassering). Vern om privatsfæren koster i disse
-dager.</p>
-
-<p>Takk til Jan Kristian Jensen i Statens Vegvesen for tips om
-dokumentasjon på vegvesenets REST-API.</p>

- <div class="date">16th September 2014</div>
- <div class="body"><p>The <a href="https://www.debian.org/">Debian</a> installer could be
-a lot quicker. When we install more than 2000 packages in
-<a href="http://www.skolelinux.org/">Skolelinux / Debian Edu</a> using
-tasksel in the installer, unpacking the binary packages take forever.
-A part of the slow I/O issue was discussed in
-<a href="https://bugs.debian.org/613428">bug #613428</a> about too
-much file system sync-ing done by dpkg, which is the package
-responsible for unpacking the binary packages. Other parts (like code
-executed by postinst scripts) might also sync to disk during
-installation. All this sync-ing to disk do not really make sense to
-me. If the machine crash half-way through, I start over, I do not try
-to salvage the half installed system. So the failure sync-ing is
-supposed to protect against, hardware or system crash, is not really
-relevant while the installer is running.</p>
-
-<p>A few days ago, I thought of a way to get rid of all the file
-system sync()-ing in a fairly non-intrusive way, without the need to
-change the code in several packages. The idea is not new, but I have
-not heard anyone propose the approach using dpkg-divert before. It
-depend on the small and clever package
-<a href="https://packages.qa.debian.org/eatmydata">eatmydata</a>, which
-uses LD_PRELOAD to replace the system functions for syncing data to
-disk with functions doing nothing, thus allowing programs to live
-dangerous while speeding up disk I/O significantly. Instead of
-modifying the implementation of dpkg, apt and tasksel (which are the
-packages responsible for selecting, fetching and installing packages),
-it occurred to me that we could just divert the programs away, replace
-them with a simple shell wrapper calling
-"eatmydata $program $@", to get the same effect.
-Two days ago I decided to test the idea, and wrapped up a simple
-implementation for the Debian Edu udeb.</p>
-
-<p>The effect was stunning. In my first test it reduced the running
-time of the pkgsel step (installing tasks) from 64 to less than 44
-minutes (20 minutes shaved off the installation) on an old Dell
-Latitude D505 machine. I am not quite sure what the optimised time
-would have been, as I messed up the testing a bit, causing the debconf
-priority to get low enough for two questions to pop up during
-installation. As soon as I saw the questions I moved the installation
-along, but do not know how long the question were holding up the
-installation. I did some more measurements using Debian Edu Jessie,
-and got these results. The time measured is the time stamp in
-/var/log/syslog between the "pkgsel: starting tasksel" and the
-"pkgsel: finishing up" lines, if you want to do the same measurement
-yourself. In Debian Edu, the tasksel dialog do not show up, and the
-timing thus do not depend on how quickly the user handle the tasksel
-dialog.</p>

-<p>The test is done using a netinst ISO on a USB stick, so some of the
-time is spent downloading packages. The connection to the Internet
-was 100Mbit/s during testing, so downloading should not be a
-significant factor in the measurement. Download typically took a few
-seconds to a few minutes, depending on the amount of packages being
-installed.</p>
-
-<p>The speedup is implemented by using two hooks in
-<a href="https://www.debian.org/devel/debian-installer/">Debian
-Installer</a>, the pre-pkgsel.d hook to set up the diverts, and the
-finish-install.d hook to remove the divert at the end of the
-installation. I picked the pre-pkgsel.d hook instead of the
-post-base-installer.d hook because I test using an ISO without the
-eatmydata package included, and the post-base-installer.d hook in
-Debian Edu can only operate on packages included in the ISO. The
-negative effect of this is that I am unable to activate this
-optimization for the kernel installation step in d-i. If the code is
-moved to the post-base-installer.d hook, the speedup would be larger
-for the entire installation.</p>
-
-<p>I've implemented this in the
-<a href="https://packages.qa.debian.org/debian-edu-install">debian-edu-install</a>
-git repository, and plan to provide the optimization as part of the
-Debian Edu installation. If you want to test this yourself, you can
-create two files in the installer (or in an udeb). One shell script
-need do go into /usr/lib/pre-pkgsel.d/, with content like this:</p>
-
-<p><blockquote><pre>
-#!/bin/sh
-set -e
-. /usr/share/debconf/confmodule
-info() {
- logger -t my-pkgsel "info: $*"
-}
-error() {
- logger -t my-pkgsel "error: $*"
-}
-override_install() {
- apt-install eatmydata || true
- if [ -x /target/usr/bin/eatmydata ] ; then
- for bin in dpkg apt-get aptitude tasksel ; do
- file=/usr/bin/$bin
- # Test that the file exist and have not been diverted already.
- if [ -f /target$file ] ; then
- info "diverting $file using eatmydata"
- printf "#!/bin/sh\neatmydata $bin.distrib \"\$@\"\n" \
- > /target$file.edu
- chmod 755 /target$file.edu
- in-target dpkg-divert --package debian-edu-config \
- --rename --quiet --add $file
- ln -sf ./$bin.edu /target$file
- else
- error "unable to divert $file, as it is missing."
- fi
- done
- else
- error "unable to find /usr/bin/eatmydata after installing the eatmydata pacage"
- fi
-}
-
-override_install
-</pre></blockquote></p>
-
-<p>To clean up, another shell script should go into
-/usr/lib/finish-install.d/ with code like this:
-
-<p><blockquote><pre>
-#! /bin/sh -e
-. /usr/share/debconf/confmodule
-error() {
- logger -t my-finish-install "error: $@"
-}
-remove_install_override() {
- for bin in dpkg apt-get aptitude tasksel ; do
- file=/usr/bin/$bin
- if [ -x /target$file.edu ] ; then
- rm /target$file
- in-target dpkg-divert --package debian-edu-config \
- --rename --quiet --remove $file
- rm /target$file.edu
- else
- error "Missing divert for $file."
- fi
- done
- sync # Flush file buffers before continuing
-}
-
-remove_install_override
-</pre></blockquote></p>
-
-<p>In Debian Edu, I placed both code fragments in a separate script
-edu-eatmydata-install and call it from the pre-pkgsel.d and
-finish-install.d scripts.</p>
-
-<p>By now you might ask if this change should get into the normal
-Debian installer too? I suspect it should, but am not sure the
-current debian-installer coordinators find it useful enough. It also
-depend on the side effects of the change. I'm not aware of any, but I
-guess we will see if the change is safe after some more testing.
-Perhaps there is some package in Debian depending on sync() and
-fsync() having effect? Perhaps it should go into its own udeb, to
-allow those of us wanting to enable it to do so without affecting
-everyone.</p>
-
-<p>Update 2014-09-24: Since a few days ago, enabling this optimization
-will break installation of all programs using gnutls because of
-<a href="https://bugs.debian.org/702711">bug #702711</a>. An updated
-eatmydata package in Debian will solve it.</p>
-
-<p>Update 2014-10-17: The bug mentioned above is fixed in testing and
-the optimization work again. And I have discovered that the
-dpkg-divert trick is not really needed and implemented a slightly
-simpler approach as part of the debian-edu-install package. See
-tools/edu-eatmydata-install in the source package.</p>

- <div class="date">10th September 2014</div>
- <div class="body"><p>Yesterday, I had the pleasure of attending a talk with the
-<a href="http://www.nuug.no/">Norwegian Unix User Group</a> about
-<a href="http://www.nuug.no/aktiviteter/20140909-sks-keyservers/">the
-OpenPGP keyserver pool sks-keyservers.net</a>, and was very happy to
-learn that there is a large set of publicly available key servers to
-use when looking for peoples public key. So far I have used
-subkeys.pgp.net, and some times wwwkeys.nl.pgp.net when the former
-were misbehaving, but those days are ended. The servers I have used
-up until yesterday have been slow and some times unavailable. I hope
-those problems are gone now.</p>
-
-<p>Behind the round robin DNS entry of the
-<a href="https://sks-keyservers.net/">sks-keyservers.net</a> service
-there is a pool of more than 100 keyservers which are checked every
-day to ensure they are well connected and up to date. It must be
-better than what I have used so far. :)</p>
-
-<p>Yesterdays speaker told me that the service is the default
-keyserver provided by the default configuration in GnuPG, but this do
-not seem to be used in Debian. Perhaps it should?</p>
-
-<p>Anyway, I've updated my ~/.gnupg/options file to now include this
-line:</p>
-
-<p><blockquote><pre>
-keyserver pool.sks-keyservers.net
-</pre></blockquote></p>
-
-<p>With GnuPG version 2 one can also locate the keyserver using SRV
-entries in DNS. Just for fun, I did just that at work, so now every
-user of GnuPG at the University of Oslo should find a OpenGPG
-keyserver automatically should their need it:</p>
-
-<p><blockquote><pre>
-% host -t srv _pgpkey-http._tcp.uio.no
-_pgpkey-http._tcp.uio.no has SRV record 0 100 11371 pool.sks-keyservers.net.
-%
-</pre></blockquote></p>
-
-<p>Now if only
-<a href="http://ietfreport.isoc.org/idref/draft-shaw-openpgp-hkp/">the
-HKP lookup protocol</a> supported finding signature paths, I would be
-very happy. It can look up a given key or search for a user ID, but I
-normally do not want that, but to find a trust path from my key to
-another key. Given a user ID or key ID, I would like to find (and
-download) the keys representing a signature path from my key to the
-key in question, to be able to get a trust path between the two keys.
-This is as far as I can tell not possible today. Perhaps something
-for a future version of the protocol?</p>
