  25       <div class="body"><p>I use the <a href="https://sourceforge.net/p/lsdvd/">lsdvd tool</a>
  26 to handle my fairly large DVD collection.  It is a nice command line
  27 tool to get details about a DVD, like title, tracks, track length,
  28 etc, in XML, perl or human readable format.  But lsdvd have not seen
  29 any new development since 2006 and had a few irritating bugs affecting
  30 its use with some DVDs.  Upstream seemed to be dead, and in January I
  31 sent a small probe asking for a version control repository for the
  32 project, without any reply.  But I use it regularly and would like to
  33 get <a href="https://packages.qa.debian.org/lsdvd">an updated version
  34 into Debian</a>.  So two weeks ago I tried harder to get in touch with
  35 the project admin, and after getting a reply from him explaining that
  36 he was no longer interested in the project, I asked if I could take
  37 over.  And yesterday, I became project admin.</p>
  38
  39 <p>I've been in touch with a Gentoo developer and the Debian
  40 maintainer interested in joining forces to maintain the upstream
  41 project, and I hope we can get a new release out fairly quickly,
  42 collecting the patches spread around on the internet into on place.
  43 I've added the relevant Debian patches to the freshly created git
  44 repository, and expect the Gentoo patches to make it too.  If you got
  45 a DVD collection and care about command line tools, check out
  46 <a href="https://sourceforge.net/p/lsdvd/git/ci/master/tree/">the git source</a> and join
  47 <a href="https://sourceforge.net/p/lsdvd/mailman/">the project mailing
  48 list</a>. :)</p>

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

  72
  73 <p>Boksen er tydelig merket «Kapsch >>>», logoen til
  74 <a href="http://www.kapsch.net/">det sveitsiske selskapet Kapsch</a> som
  75 blant annet lager sensorsystemer for veitrafikk.  Men de lager mye
  76 forskjellig, og jeg kjente ikke igjen boksen på utseendet etter en
  77 kjapp titt på produktlista til selskapet.</p>
  78
  79 <p>I og med at boksen henger over veien E16, en riksvei vedlikeholdt
  80 av Statens Vegvesen, så antok jeg at det burde være mulig å bruke
  81 REST-API-et som gir tilgang til vegvesenets database over veier,
  82 skilter og annet veirelatert til å finne ut hva i alle dager dette
  83 kunne være.  De har både
  84 <a href="https://www.vegvesen.no/nvdb/api/dokumentasjon/datakatalog">en
  85 datakatalog</a> og
  86 <a href="https://www.vegvesen.no/nvdb/api/dokumentasjon/sok">et
  87 søk</a>, der en kan søke etter ulike typer oppføringer innen for et
  88 gitt geografisk område.  Jeg laget et enkelt shell-script for å hente
  89 ut antall av en gitt type innenfor området skibrua dekker, og listet
  90 opp navnet på typene som ble funnet.  Orket ikke slå opp hvordan
  91 URL-koding av aktuelle strenger kunne gjøres mer generisk, og brukte
  92 en stygg sed-linje i stedet.</p>

 264
 265 <p>Av disse ser ID 775 og 862 mest relevant ut.  ID 775 antar jeg
 266 refererer til fotoboksen som står like ved brua, mens
 267 «Reisetidsregistreringspunkt» kanskje kan være boksen som henger der.
 268 Hvordan finner jeg så ut hva dette kan være for noe.  En titt på
 269 <a href="http://labs.vegdata.no/nvdb-datakatalog/862-Reisetidsregistreringspunkt/">datakatalogsiden
 270 for ID 862/Reisetidsregistreringspunkt</a> viser at det er finnes 53
 271 slike målere i Norge, og hvor de er plassert, men gir ellers få
 272 detaljer.  Det er plassert 40 på østlandet og 13 i Trondheimsregionen.
 273 Men siden nevner «AutoPASS», og hvis en slår opp oppføringen på
 274 Sollihøgda nevner den «Ciber AS» som ID for eksternt system.  (Kan det
 275 være snakk om
 276 <a href="http://www.proff.no/selskap/ciber-norge-as/oslo/internettdesign-og-programmering/Z0I3KMF4/">Ciber
 277 Norge AS</a>, et selskap eid av Ciber Europe Bv?)  Et nettsøk på
 278  «Ciber AS autopass» fører meg til en artikkel fra NRK Trøndelag i
 279  2013 med tittel
 280 «<a href="http://www.nrk.no/trondelag/sjekk-dette-hvis-du-vil-unnga-ko-1.11327947">Sjekk
 281 dette hvis du vil unngå kø</a>».  Artikkelen henviser til vegvesenets
 282 nettside
 283 <a href="http://www.reisetider.no/reisetid/forside.html">reisetider.no</a>
 284 som har en
 285 <a href="http://www.reisetider.no/reisetid/omrade.html?omrade=5">kartside
 286 for Østlandet</a> som viser at det måles mellom Sandvika og Sollihøgda.
 287 Det kan dermed se ut til at jeg har funnet ut hva boksene gjør.</p>
 288
 289 <p>Hvis det stemmer, så er dette bokser som leser av AutoPASS-ID-en
 290 til alle passerende biler med AutoPASS-brikke, og dermed gjør det mulig
 291 for de som kontrollerer boksene å holde rede på hvor en gitt bil er
 292 når den passerte et slikt målepunkt.  NRK-artikkelen forteller at
 293 denne informasjonen i dag kun brukes til å koble to
 294 AutoPASS-brikkepasseringer passeringer sammen for å beregne
 295 reisetiden, og at bruken er godkjent av Datatilsynet.  Det er desverre
 296 ikke mulig for en sjåfør som passerer under en slik boks å kontrollere
 297 at AutoPASS-ID-en kun brukes til dette i dag og i fremtiden.</p>
 298
 299 <p>I tillegg til denne type AutoPASS-sniffere vet jeg at det også
 300 finnes mange automatiske stasjoner som tar betalt pr. passering (aka
 301 bomstasjoner), og der lagres informasjon om tid, sted og bilnummer i
 302 10 år.  Finnes det andre slike sniffere plassert ut på veiene?</p>
 303
 304 <p>Personlig har jeg valgt å ikke bruke AutoPASS-brikke, for å gjøre
 305 det vanskeligere og mer kostbart for de som vil invadere privatsfæren
 306 og holde rede på hvor bilen min beveger seg til enhver tid.  Jeg håper
 307 flere vil gjøre det samme, selv om det gir litt høyere private
 308 utgifter (dyrere bompassering).  Vern om privatsfæren koster i disse
 309 dager.</p>

 311 <p>Takk til Jan Kristian Jensen i Statens Vegvesen for tips om
 312 dokumentasjon på vegvesenets REST-API.</p>

 326       <div class="date">16th September 2014</div>
 327       <div class="body"><p>The <a href="https://www.debian.org/">Debian</a> installer could be
 328 a lot quicker.  When we install more than 2000 packages in
 329 <a href="http://www.skolelinux.org/">Skolelinux / Debian Edu</a> using
 330 tasksel in the installer, unpacking the binary packages take forever.
 331 A part of the slow I/O issue was discussed in
 332 <a href="https://bugs.debian.org/613428">bug #613428</a> about too
 333 much file system sync-ing done by dpkg, which is the package
 334 responsible for unpacking the binary packages.  Other parts (like code
 335 executed by postinst scripts) might also sync to disk during
 336 installation.  All this sync-ing to disk do not really make sense to
 337 me.  If the machine crash half-way through, I start over, I do not try
 338 to salvage the half installed system.  So the failure sync-ing is
 339 supposed to protect against, hardware or system crash, is not really
 340 relevant while the installer is running.</p>
 341
 342 <p>A few days ago, I thought of a way to get rid of all the file
 343 system sync()-ing in a fairly non-intrusive way, without the need to
 344 change the code in several packages.  The idea is not new, but I have
 345 not heard anyone propose the approach using dpkg-divert before.  It
 346 depend on the small and clever package
 347 <a href="https://packages.qa.debian.org/eatmydata">eatmydata</a>, which
 348 uses LD_PRELOAD to replace the system functions for syncing data to
 349 disk with functions doing nothing, thus allowing programs to live
 350 dangerous while speeding up disk I/O significantly.  Instead of
 351 modifying the implementation of dpkg, apt and tasksel (which are the
 352 packages responsible for selecting, fetching and installing packages),
 353 it occurred to me that we could just divert the programs away, replace
 354 them with a simple shell wrapper calling
 355 "eatmydata&nbsp;$program&nbsp;$@", to get the same effect.
 356 Two days ago I decided to test the idea, and wrapped up a simple
 357 implementation for the Debian Edu udeb.</p>
 358
 359 <p>The effect was stunning.  In my first test it reduced the running
 360 time of the pkgsel step (installing tasks) from 64 to less than 44
 361 minutes (20 minutes shaved off the installation) on an old Dell
 362 Latitude D505 machine.  I am not quite sure what the optimised time
 363 would have been, as I messed up the testing a bit, causing the debconf
 364 priority to get low enough for two questions to pop up during
 365 installation.  As soon as I saw the questions I moved the installation
 366 along, but do not know how long the question were holding up the
 367 installation.  I did some more measurements using Debian Edu Jessie,
 368 and got these results.  The time measured is the time stamp in
 369 /var/log/syslog between the "pkgsel: starting tasksel" and the
 370 "pkgsel: finishing up" lines, if you want to do the same measurement
 371 yourself.  In Debian Edu, the tasksel dialog do not show up, and the
 372 timing thus do not depend on how quickly the user handle the tasksel
 373 dialog.</p>

 424 significant factor in the measurement.  Download typically took a few
 425 seconds to a few minutes, depending on the amount of packages being
 426 installed.</p>
 427
 428 <p>The speedup is implemented by using two hooks in
 429 <a href="https://www.debian.org/devel/debian-installer/">Debian
 430 Installer</a>, the pre-pkgsel.d hook to set up the diverts, and the
 431 finish-install.d hook to remove the divert at the end of the
 432 installation.  I picked the pre-pkgsel.d hook instead of the
 433 post-base-installer.d hook because I test using an ISO without the
 434 eatmydata package included, and the post-base-installer.d hook in
 435 Debian Edu can only operate on packages included in the ISO.  The
 436 negative effect of this is that I am unable to activate this
 437 optimization for the kernel installation step in d-i.  If the code is
 438 moved to the post-base-installer.d hook, the speedup would be larger
 439 for the entire installation.</p>
 440
 441 <p>I've implemented this in the
 442 <a href="https://packages.qa.debian.org/debian-edu-install">debian-edu-install</a>
 443 git repository, and plan to provide the optimization as part of the
 444 Debian Edu installation.  If you want to test this yourself, you can
 445 create two files in the installer (or in an udeb).  One shell script
 446 need do go into /usr/lib/pre-pkgsel.d/, with content like this:</p>
 447
 448 <p><blockquote><pre>
 449 #!/bin/sh
 450 set -e
 451 . /usr/share/debconf/confmodule
 452 info() {
 453     logger -t my-pkgsel "info: $*"
 454 }
 455 error() {
 456     logger -t my-pkgsel "error: $*"
 457 }
 458 override_install() {
 459     apt-install eatmydata || true
 460     if [ -x /target/usr/bin/eatmydata ] ; then
 461         for bin in dpkg apt-get aptitude tasksel ; do
 462             file=/usr/bin/$bin
 463             # Test that the file exist and have not been diverted already.
 464             if [ -f /target$file ] ; then
 465                 info "diverting $file using eatmydata"
 466                 printf "#!/bin/sh\neatmydata $bin.distrib \"\$@\"\n" \
 467                     > /target$file.edu
 468                 chmod 755 /target$file.edu
 469                 in-target dpkg-divert --package debian-edu-config \
 470                     --rename --quiet --add $file
 471                 ln -sf ./$bin.edu /target$file
 472             else
 473                 error "unable to divert $file, as it is missing."
 474             fi
 475         done
 476     else
 477         error "unable to find /usr/bin/eatmydata after installing the eatmydata pacage"
 478     fi
 479 }
 480
 481 override_install
 482 </pre></blockquote></p>
 483
 484 <p>To clean up, another shell script should go into
 485 /usr/lib/finish-install.d/ with code like this:
 486
 487 <p><blockquote><pre>
 488 #! /bin/sh -e
 489 . /usr/share/debconf/confmodule
 490 error() {
 491     logger -t my-finish-install "error: $@"
 492 }
 493 remove_install_override() {
 494     for bin in dpkg apt-get aptitude tasksel ; do
 495         file=/usr/bin/$bin
 496         if [ -x /target$file.edu ] ; then
 497             rm /target$file
 498             in-target dpkg-divert --package debian-edu-config \
 499                 --rename --quiet --remove $file
 500             rm /target$file.edu
 501         else
 502             error "Missing divert for $file."
 503         fi
 504     done
 505     sync # Flush file buffers before continuing
 506 }
 507
 508 remove_install_override
 509 </pre></blockquote></p>
 510
 511 <p>In Debian Edu, I placed both code fragments in a separate script
 512 edu-eatmydata-install and call it from the pre-pkgsel.d and
 513 finish-install.d scripts.</p>
 514
 515 <p>By now you might ask if this change should get into the normal
 516 Debian installer too?  I suspect it should, but am not sure the
 517 current debian-installer coordinators find it useful enough.  It also
 518 depend on the side effects of the change.  I'm not aware of any, but I
 519 guess we will see if the change is safe after some more testing.
 520 Perhaps there is some package in Debian depending on sync() and
 521 fsync() having effect?  Perhaps it should go into its own udeb, to
 522 allow those of us wanting to enable it to do so without affecting
 523 everyone.</p>
 524
 525 <p>Update 2014-09-24: Since a few days ago, enabling this optimization
 526 will break installation of all programs using gnutls because of
 527 <ahref="https://bugs.debian.org/702711">bug #702711.  An updated
 528 eatmydata package in Debian will solve it.</p>

 542       <div class="date">10th September 2014</div>
 543       <div class="body"><p>Yesterday, I had the pleasure of attending a talk with the
 544 <a href="http://www.nuug.no/">Norwegian Unix User Group</a> about
 545 <a href="http://www.nuug.no/aktiviteter/20140909-sks-keyservers/">the
 546 OpenPGP keyserver pool sks-keyservers.net</a>, and was very happy to
 547 learn that there is a large set of publicly available key servers to
 548 use when looking for peoples public key.  So far I have used
 549 subkeys.pgp.net, and some times wwwkeys.nl.pgp.net when the former
 550 were misbehaving, but those days are ended.  The servers I have used
 551 up until yesterday have been slow and some times unavailable.  I hope
 552 those problems are gone now.</p>
 553
 554 <p>Behind the round robin DNS entry of the
 555 <a href="https://sks-keyservers.net/">sks-keyservers.net</a> service
 556 there is a pool of more than 100 keyservers which are checked every
 557 day to ensure they are well connected and up to date.  It must be
 558 better than what I have used so far. :)</p>
 559
 560 <p>Yesterdays speaker told me that the service is the default
 561 keyserver provided by the default configuration in GnuPG, but this do
 562 not seem to be used in Debian.  Perhaps it should?</p>
 563
 564 <p>Anyway, I've updated my ~/.gnupg/options file to now include this
 565 line:</p>
 566
 567 <p><blockquote><pre>
 568 keyserver pool.sks-keyservers.net
 569 </pre></blockquote></p>
 570
 571 <p>With GnuPG version 2 one can also locate the keyserver using SRV
 572 entries in DNS.  Just for fun, I did just that at work, so now every
 573 user of GnuPG at the University of Oslo should find a OpenGPG
 574 keyserver automatically should their need it:</p>
 575
 576 <p><blockquote><pre>
 577 % host -t srv _pgpkey-http._tcp.uio.no
 578 _pgpkey-http._tcp.uio.no has SRV record 0 100 11371 pool.sks-keyservers.net.
 579 %
 580 </pre></blockquote></p>
 581
 582 <p>Now if only
 583 <a href="http://ietfreport.isoc.org/idref/draft-shaw-openpgp-hkp/">the
 584 HKP lookup protocol</a> supported finding signature paths, I would be
 585 very happy.  It can look up a given key or search for a user ID, but I
 586 normally do not want that, but to find a trust path from my key to
 587 another key.  Given a user ID or key ID, I would like to find (and
 588 download) the keys representing a signature path from my key to the
 589 key in question, to be able to get a trust path between the two keys.
 590 This is as far as I can tell not possible today.  Perhaps something
 591 for a future version of the protocol?</p>

 605       <div class="date">25th August 2014</div>
 606       <div class="body"><p>Two years later, I am still not sure if it is legal here in Norway
 607 to use or publish a video in H.264 or MPEG4 format edited by the
 608 commercially licensed video editors, without limiting the use to
 609 create "personal" or "non-commercial" videos or get a license
 610 agreement with <a href="http://www.mpegla.com">MPEG LA</a>.  If one
 611 want to publish and broadcast video in a non-personal or commercial
 612 setting, it might be that those tools can not be used, or that video
 613 format can not be used, without breaking their copyright license.  I
 614 am not sure.

 616 then</a>, I found that the copyright license terms for Adobe Premiere
 617 and Apple Final Cut Pro both specified that one could not use the
 618 program to produce anything else without a patent license from MPEG
 619 LA.  The issue is not limited to those two products, though.  Other
 620 much used products like those from Avid and Sorenson Media have terms
 621 of use are similar to those from Adobe and Apple.  The complicating
 622 factor making me unsure if those terms have effect in Norway or not is
 623 that the patents in question are not valid in Norway, but copyright
 624 licenses are.</p>

 890       <div class="date">31st July 2014</div>
 891       <div class="body"><p>The complete and free “out of the box” software solution for
 892 schools, <a href="http://www.skolelinux.org/">Debian Edu /
 893 Skolelinux</a>, is used quite a lot in Germany, and one of the people
 894 involved is Bernd Zeitzen, who show up on the project mailing lists
 895 from time to time with interesting questions and tips on how to adjust
 896 the setup.  I managed to interview him this summer.</p>
 897
 898 <p><strong>Who are you, and how do you spend your days?</strong></p>
 899
 900 <p>My name is Bernd Zeitzen and I'm married with Hedda, a self
 901 employed physiotherapist.  My former profession is tool maker, but I
 902 haven't worked for 30 years in this job.  30 years ago I started to
 903 support my wife and become her officeworker and a few years later the
 904 administrator for a small computer network, today based on Ubuntu
 905 Server (Samba, OpenVPN). For her daily work she has to use Windows
 906 Desktops because the software she needs to organize her business only
 907 works with Windows . :-(</p>
 908
 909 <p>In 1988 we started with one PC and DOS, then I learned to use
 910 Windows 98, 2000, XP, …, 8, Ubuntu, MacOSX.  Today we are running a
 911 Linux server with 6 Windows clients and 10 persons (teacher of
 912 children with special needs, speech therapist, occupational therapist,
 913 psychologist and officeworkers) using our Samba shares via OpenVPN to
 914 work with the documentations of our patients.</p>
 915
 916 <p><strong>How did you get in contact with the Skolelinux / Debian Edu
 917 project?</strong></p>
 918
 919 <p>Two years ago a friend of mine asked me, if I want to get a job in
 920 his school (<a href="http://www.gymnasium-harsewinkel.de/">Gymnasium
 921 Harsewinkel</a>).  They started with Skolelinux / Debian Edu and they
 922 were looking for people to give support to the teachers using the
 923 software and the network and teaching the pupils increasing their
 924 computer skills in optional lessons.  I'm spending 4-6 hours a week
 925 with this job.</p>
 926
 927 <p><strong>What do you see as the advantages of Skolelinux / Debian
 928 Edu?</strong></p>
 929
 930 <p>The independence.</p>
 931
 932 <p>First: Every person is allowed to use, share and develop the
 933 software. Even if you are poor, you are allowed to use the software
 934 included in Skolelinux/Debian Edu and all the other Free Software.</p>
 935
 936 <p>Second: The software runs on old machines and this gives us the
 937 possibility to recycle computers, weeded out from offices.  The
 938 servers and desktops are running for more than two years and they are
 939 working reliable. </p>
 940
 941 <p>We have two servers (one tjener and one terminal server), 45
 942 workstations in three classrooms and seven laptops as a mobile
 943 solution for all classrooms.  These machines are all booting from the
 944 terminal server.  In the moment we are installing 30 laptops as mobile
 945 workstations.  Then the pupils have the possibility to work with these
 946 machines in their classrooms.  Internet access is realized by a WLAN
 947 router, connected to the schools network. This is all done without a
 948 dedicated system administrator or a computer science teacher.</p>
 949
 950 <p><strong>What do you see as the disadvantages of Skolelinux / Debian
 951 Edu?</strong></p>
 952
 953 <p>Teachers and pupils are Windows users.  &lt;Irony on&gt; And Linux
 954 isn't cool. It's software for freaks using the command line. &lt;Irony
 955 off&gt; They don't realize the stability of the system. </p>
 956
 957 <p><strong>Which free software do you use daily?</strong></p>
 958
 959 <p>Firefox, Thunderbird, LibreOffice, Ubuntu Server 12.04 (Samba,
 960 Apache, MySQL, Joomla!, … and Skolelinux / Debian Edu)</p>
 961
 962 <p><strong>Which strategy do you believe is the right one to use to
 963 get schools to use free software?</strong></p>
 964
 965 <p>In Germany we have the situation: every school is free to decide
 966 which software they want to use. This decision is influenced by
 967 teachers who learned to use Windows and MS Office. They buy a PC with
 968 Windows preinstalled and an additional testing version of MS
 969 Office. They don't know about the possibility to use Free Software
 970 instead.  Another problem are the publisher of school books.  They
 971 develop their software, added to the school books, for Windows.</p>

 988 <a href="http://free-culture.cc/">Free Culture</a> by Lawrence Lessig,
 989 to get a Norwegian text explaining the problems with todays copyright
 990 law.  Yesterday, I finally completed translated the book text.  There
 991 are still some foot/end notes left to translate, the colophon page
 992 need to be rewritten, and a few words and phrases still need to be
 993 translated, but the Norwegian text is ready for the first proof
 994 reading. :) More spell checking is needed, and several illustrations
 995 need to be cleaned up.  The work stopped up because I had to give
 996 priority to other projects the last year, and the progress graph of
 997 the translation show this very well:</p>

1025       <div class="date">17th June 2014</div>
1026       <div class="body"><p>The <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux
1027 project</a> provide an instruction manual for teachers, system
1028 administrators and other users that contain useful tips for setting up
1029 and maintaining a Debian Edu installation.  This text is about how the
1030 text processing of this manual is handled in the project.</p>
1031
1032 <p>One goal of the project is to provide information in the native
1033 language of its users, and for this we need to handle translations.
1034 But we also want to make sure each language contain the same
1035 information, so for this we need a good way to keep the translations
1036 in sync.  And we want it to be easy for our users to improve the
1037 documentation, avoiding the need to learn special formats or tools to
1038 contribute, and the obvious way to do this is to make it possible to
1039 edit the documentation using a web browser.  We also want it to be
1040 easy for translators to keep the translation up to date, and give them
1041 help in figuring out what need to be translated. Here is the list of
1042 tools and the process we have found trying to reach all these
1043 goals.</p>
1044
1045 <p>We maintain the authoritative source of our manual in the
1046 <a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/">Debian
1047 wiki</a>, as several wiki pages written in English.  It consist of one
1048 front page with references to the different chapters, several pages
1049 for each chapter, and finally one "collection page" gluing all the
1050 chapters together into one large web page (aka
1051 <a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/AllInOne">the
1052 AllInOne page</a>).  The AllInOne page is the one used for further
1053 processing and translations.  Thanks to the fact that the
1054 <a href="http://moinmo.in/">MoinMoin</a> installation on
1055 wiki.debian.org support exporting pages in
1056 <a href="http://www.docbook.org/">the Docbook format</a>, we can fetch
1057 the list of pages to export using the raw version of the AllInOne
1058 page, loop over each of them to generate a Docbook XML version of the
1059 manual.  This process also download images and transform image
1060 references to use the locally downloaded images.  The generated
1061 Docbook XML files are slightly broken, so some post-processing is done
1062 using the <tt>documentation/scripts/get_manual</tt> program, and the
1063 result is a nice Docbook XML file (debian-edu-wheezy-manual.xml) and
1064 a handfull of images.  The XML file can now be used to generate PDF, HTML
1065 and epub versions of the English manual.  This is the basic step of
1066 our process, making PDF (using dblatex), HTML (using xsltproc) and
1067 epub (using dbtoepub) version from Docbook XML, and the resulting files
1068 are placed in the debian-edu-doc-en binary package.</p>
1069
1070 <p>But English documentation is not enough for us.  We want translated
1071 documentation too, and we want to make it easy for translators to
1072 track the English original.  For this we use the
1073 <a href="http://packages.qa.debian.org/p/poxml.html">poxml</a> package,
1074 which allow us to transform the English Docbook XML file into a
1075 translation file (a .pot file), usable with the normal gettext based
1076 translation tools used by those translating free software.  The pot
1077 file is used to create and maintain translation files (several .po
1078 files), which the translations update with the native language
1079 translations of all titles, paragraphs and blocks of text in the
1080 original.  The next step is combining the original English Docbook XML
1081 and the translation file (say debian-edu-wheezy-manual.nb.po), to
1082 create a translated Docbook XML file (in this case
1083 debian-edu-wheezy-manual.nb.xml).  This translated (or partly
1084 translated, if the translation is not complete) Docbook XML file can
1085 then be used like the original to create a PDF, HTML and epub version
1086 of the documentation.</p>
1087
1088 <p>The translators use different tools to edit the .po files.  We
1089 recommend using
1090 <a href="http://www.kde.org/applications/development/lokalize/">lokalize</a>,
1091 while some use emacs and vi, others can use web based editors like
1092 <a href="http://pootle.translatehouse.org/">Poodle</a> or
1093 <a href="https://www.transifex.com/">Transifex</a>.  All we care about
1094 is where the .po file end up, in our git repository.  Updated
1095 translations can either be committed directly to git, or submitted as
1096 <a href="https://bugs.debian.org/src:debian-edu-doc">bug reports
1097 against the debian-edu-doc package</a>.</p>
1098
1099 <p>One challenge is images, which both might need to be translated (if
1100 they show translated user applications), and are needed in different
1101 formats when creating PDF and HTML versions (epub is a HTML version in
1102 this regard).  For this we transform the original PNG images to the
1103 needed density and format during build, and have a way to provide
1104 translated images by storing translated versions in
1105 images/$LANGUAGECODE/.  I am a bit unsure about the details here.  The
1106 package maintainers know more.</p>
1107
1108 <p>If you wonder what the result look like, we provide
1109 <a href="http://maintainer.skolelinux.org/debian-edu-doc/">the content
1110 of the documentation packages on the web</a>.  See for example the
1111 <a href="http://maintainer.skolelinux.org/debian-edu-doc/it/debian-edu-wheezy-manual.pdf">Italian
1112 PDF version</a> or the
1113 <a href="http://maintainer.skolelinux.org/debian-edu-doc/de/debian-edu-wheezy-manual.html">German
1114 HTML version</a>.  We do not yet build the epub version by default,
1115 but perhaps it will be done in the future.</p>

1169 <p>Takk til gode venner på foreningen NUUGs IRC-kanal
1170 <a href="irc://irc.freenode.net/%23nuug">#nuug på irc.freenode.net</a>
1171 for tipsene som fikk meg i mål</a>.</p>
1172
1173 <p><strong>Oppdatering 2014-06-17</strong>: Etter at jeg publiserte
1174 denne, ble jeg tipset om bloggposten
1175 "<a href="http://ingvar.blog.redpill-linpro.com/2012/05/31/downloading-hd-content-from-tv-nrk-no/">Downloading
1176 HD content from tv.nrk.no</a>" av Ingvar Hagelund, som har alternativ
1177 implementasjon og tips for å lage mkv-fil med undertekstene inkludert.
1178 Kanskje den passer bedre for deg?  I tillegg ble feilen i youtube-dl
1179 ble fikset litt senere ut på dagen i går, samt at youtube-dl fikk
1180 støtte for å laste ned undertitler.  Takk til Anders Einar Hilden for
1181 god innsats og youtube-dl-utviklerne for rask respons.</p>
