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

  34
  35 <p>Boksen er tydelig merket «Kapsch >>>», logoen til
  36 <a href="http://www.kapsch.net/">det sveitsiske selskapet Kapsch</a> som
  37 blant annet lager sensorsystemer for veitrafikk.  Men de lager mye
  38 forskjellig, og jeg kjente ikke igjen boksen på utseendet etter en
  39 kjapp titt på produktlista til selskapet.</p>
  40
  41 <p>I og med at boksen henger over veien E16, en riksvei vedlikeholdt
  42 av Statens Vegvesen, så antok jeg at det burde være mulig å bruke
  43 REST-API-et som gir tilgang til vegvesenets database over veier,
  44 skilter og annet veirelatert til å finne ut hva i alle dager dette
  45 kunne være.  De har både
  46 <a href="https://www.vegvesen.no/nvdb/api/dokumentasjon/datakatalog">en
  47 datakatalog</a> og
  48 <a href="https://www.vegvesen.no/nvdb/api/dokumentasjon/sok">et
  49 søk</a>, der en kan søke etter ulike typer oppføringer innen for et
  50 gitt geografisk område.  Jeg laget et enkelt shell-script for å hente
  51 ut antall av en gitt type innenfor området skibrua dekker, og listet
  52 opp navnet på typene som ble funnet.  Orket ikke slå opp hvordan
  53 URL-koding av aktuelle strenger kunne gjøres mer generisk, og brukte
  54 en stygg sed-linje i stedet.</p>

 226
 227 <p>Av disse ser ID 775 og 862 mest relevant ut.  ID 775 antar jeg
 228 refererer til fotoboksen som står like ved brua, mens
 229 «Reisetidsregistreringspunkt» kanskje kan være boksen som henger der.
 230 Hvordan finner jeg så ut hva dette kan være for noe.  En titt på
 231 <a href="http://labs.vegdata.no/nvdb-datakatalog/862-Reisetidsregistreringspunkt/">datakatalogsiden
 232 for ID 862/Reisetidsregistreringspunkt</a> viser at det er finnes 53
 233 slike målere i Norge, og hvor de er plassert, men gir ellers få
 234 detaljer.  Det er plassert 40 på østlandet og 13 i Trondheimsregionen.
 235 Men siden nevner «AutoPASS», og hvis en slår opp oppføringen på
 236 Sollihøgda nevner den «Ciber AS» som ID for eksternt system.  (Kan det
 237 være snakk om
 238 <a href="http://www.proff.no/selskap/ciber-norge-as/oslo/internettdesign-og-programmering/Z0I3KMF4/">Ciber
 239 Norge AS</a>, et selskap eid av Ciber Europe Bv?)  Et nettsøk på
 240  «Ciber AS autopass» fører meg til en artikkel fra NRK Trøndelag i
 241  2013 med tittel
 242 «<a href="http://www.nrk.no/trondelag/sjekk-dette-hvis-du-vil-unnga-ko-1.11327947">Sjekk
 243 dette hvis du vil unngå kø</a>».  Artikkelen henviser til vegvesenets
 244 nettside
 245 <a href="http://www.reisetider.no/reisetid/forside.html">reisetider.no</a>
 246 som har en
 247 <a href="http://www.reisetider.no/reisetid/omrade.html?omrade=5">kartside
 248 for Østlandet</a> som viser at det måles mellom Sandvika og Sollihøgda.
 249 Det kan dermed se ut til at jeg har funnet ut hva boksene gjør.</p>
 250
 251 <p>Hvis det stemmer, så er dette bokser som leser av AutoPASS-ID-en
 252 til alle passerende biler med AutoPASS-brikke, og dermed gjør det mulig
 253 for de som kontrollerer boksene å holde rede på hvor en gitt bil er
 254 når den passerte et slikt målepunkt.  NRK-artikkelen forteller at
 255 denne informasjonen i dag kun brukes til å koble to
 256 AutoPASS-brikkepasseringer passeringer sammen for å beregne
 257 reisetiden, og at bruken er godkjent av Datatilsynet.  Det er desverre
 258 ikke mulig for en sjåfør som passerer under en slik boks å kontrollere
 259 at AutoPASS-ID-en kun brukes til dette i dag og i fremtiden.</p>
 260
 261 <p>I tillegg til denne type AutoPASS-sniffere vet jeg at det også
 262 finnes mange automatiske stasjoner som tar betalt pr. passering (aka
 263 bomstasjoner), og der lagres informasjon om tid, sted og bilnummer i
 264 10 år.  Finnes det andre slike sniffere plassert ut på veiene?</p>
 265
 266 <p>Personlig har jeg valgt å ikke bruke AutoPASS-brikke, for å gjøre
 267 det vanskeligere og mer kostbart for de som vil invadere privatsfæren
 268 og holde rede på hvor bilen min beveger seg til enhver tid.  Jeg håper
 269 flere vil gjøre det samme, selv om det gir litt høyere private
 270 utgifter (dyrere bompassering).  Vern om privatsfæren koster i disse
 271 dager.</p>

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

 288       <div class="date">16th September 2014</div>
 289       <div class="body"><p>The <a href="https://www.debian.org/">Debian</a> installer could be
 290 a lot quicker.  When we install more than 2000 packages in
 291 <a href="http://www.skolelinux.org/">Skolelinux / Debian Edu</a> using
 292 tasksel in the installer, unpacking the binary packages take forever.
 293 A part of the slow I/O issue was discussed in
 294 <a href="https://bugs.debian.org/613428">bug #613428</a> about too
 295 much file system sync-ing done by dpkg, which is the package
 296 responsible for unpacking the binary packages.  Other parts (like code
 297 executed by postinst scripts) might also sync to disk during
 298 installation.  All this sync-ing to disk do not really make sense to
 299 me.  If the machine crash half-way through, I start over, I do not try
 300 to salvage the half installed system.  So the failure sync-ing is
 301 supposed to protect against, hardware or system crash, is not really
 302 relevant while the installer is running.</p>
 303
 304 <p>A few days ago, I thought of a way to get rid of all the file
 305 system sync()-ing in a fairly non-intrusive way, without the need to
 306 change the code in several packages.  The idea is not new, but I have
 307 not heard anyone propose the approach using dpkg-divert before.  It
 308 depend on the small and clever package
 309 <a href="https://packages.qa.debian.org/eatmydata">eatmydata</a>, which
 310 uses LD_PRELOAD to replace the system functions for syncing data to
 311 disk with functions doing nothing, thus allowing programs to live
 312 dangerous while speeding up disk I/O significantly.  Instead of
 313 modifying the implementation of dpkg, apt and tasksel (which are the
 314 packages responsible for selecting, fetching and installing packages),
 315 it occurred to me that we could just divert the programs away, replace
 316 them with a simple shell wrapper calling
 317 "eatmydata&nbsp;$program&nbsp;$@", to get the same effect.
 318 Two days ago I decided to test the idea, and wrapped up a simple
 319 implementation for the Debian Edu udeb.</p>
 320
 321 <p>The effect was stunning.  In my first test it reduced the running
 322 time of the pkgsel step (installing tasks) from 64 to less than 44
 323 minutes (20 minutes shaved off the installation) on an old Dell
 324 Latitude D505 machine.  I am not quite sure what the optimised time
 325 would have been, as I messed up the testing a bit, causing the debconf
 326 priority to get low enough for two questions to pop up during
 327 installation.  As soon as I saw the questions I moved the installation
 328 along, but do not know how long the question were holding up the
 329 installation.  I did some more measurements using Debian Edu Jessie,
 330 and got these results.  The time measured is the time stamp in
 331 /var/log/syslog between the "pkgsel: starting tasksel" and the
 332 "pkgsel: finishing up" lines, if you want to do the same measurement
 333 yourself.  In Debian Edu, the tasksel dialog do not show up, and the
 334 timing thus do not depend on how quickly the user handle the tasksel
 335 dialog.</p>

 382
 383 <p>The test is done using a netinst ISO on a USB stick, so some of the
 384 time is spent downloading packages.  The connection to the Internet
 385 was 100Mbit/s during testing, so downloading should not be a
 386 significant factor in the measurement.  Download typically took a few
 387 seconds to a few minutes, depending on the amount of packages being
 388 installed.</p>
 389
 390 <p>The speedup is implemented by using two hooks in
 391 <a href="https://www.debian.org/devel/debian-installer/">Debian
 392 Installer</a>, the pre-pkgsel.d hook to set up the diverts, and the
 393 finish-install.d hook to remove the divert at the end of the
 394 installation.  I picked the pre-pkgsel.d hook instead of the
 395 post-base-installer.d hook because I test using an ISO without the
 396 eatmydata package included, and the post-base-installer.d hook in
 397 Debian Edu can only operate on packages included in the ISO.  The
 398 negative effect of this is that I am unable to activate this
 399 optimization for the kernel installation step in d-i.  If the code is
 400 moved to the post-base-installer.d hook, the speedup would be larger
 401 for the entire installation.</p>
 402
 403 <p>I've implemented this in the
 404 <a href="https://packages.qa.debian.org/debian-edu-install">debian-edu-install</a>
 405 git repository, and plan to provide the optimization as part of the
 406 Debian Edu installation.  If you want to test this yourself, you can
 407 create two files in the installer (or in an udeb).  One shell script
 408 need do go into /usr/lib/pre-pkgsel.d/, with content like this:</p>
 409
 410 <p><blockquote><pre>

 446 <p>To clean up, another shell script should go into
 447 /usr/lib/finish-install.d/ with code like this:
 448
 449 <p><blockquote><pre>
 450 #! /bin/sh -e
 451 . /usr/share/debconf/confmodule
 452 error() {
 453     logger -t my-finish-install "error: $@"
 454 }
 455 remove_install_override() {
 456     for bin in dpkg apt-get aptitude tasksel ; do
 457         file=/usr/bin/$bin
 458         if [ -x /target$file.edu ] ; then
 459             rm /target$file

 466     done
 467     sync # Flush file buffers before continuing
 468 }
 469

 471 </pre></blockquote></p>
 472
 473 <p>In Debian Edu, I placed both code fragments in a separate script
 474 edu-eatmydata-install and call it from the pre-pkgsel.d and
 475 finish-install.d scripts.</p>
 476
 477 <p>By now you might ask if this change should get into the normal
 478 Debian installer too?  I suspect it should, but am not sure the
 479 current debian-installer coordinators find it useful enough.  It also
 480 depend on the side effects of the change.  I'm not aware of any, but I
 481 guess we will see if the change is safe after some more testing.
 482 Perhaps there is some package in Debian depending on sync() and
 483 fsync() having effect?  Perhaps it should go into its own udeb, to
 484 allow those of us wanting to enable it to do so without affecting
 485 everyone.</p>

 499       <div class="date">10th September 2014</div>
 500       <div class="body"><p>Yesterday, I had the pleasure of attending a talk with the
 501 <a href="http://www.nuug.no/">Norwegian Unix User Group</a> about
 502 <a href="http://www.nuug.no/aktiviteter/20140909-sks-keyservers/">the
 503 OpenPGP keyserver pool sks-keyservers.net</a>, and was very happy to
 504 learn that there is a large set of publicly available key servers to
 505 use when looking for peoples public key.  So far I have used
 506 subkeys.pgp.net, and some times wwwkeys.nl.pgp.net when the former
 507 were misbehaving, but those days are ended.  The servers I have used
 508 up until yesterday have been slow and some times unavailable.  I hope
 509 those problems are gone now.</p>
 510
 511 <p>Behind the round robin DNS entry of the
 512 <a href="https://sks-keyservers.net/">sks-keyservers.net</a> service
 513 there is a pool of more than 100 keyservers which are checked every
 514 day to ensure they are well connected and up to date.  It must be
 515 better than what I have used so far. :)</p>
 516
 517 <p>Yesterdays speaker told me that the service is the default
 518 keyserver provided by the default configuration in GnuPG, but this do
 519 not seem to be used in Debian.  Perhaps it should?</p>
 520
 521 <p>Anyway, I've updated my ~/.gnupg/options file to now include this
 522 line:</p>
 523
 524 <p><blockquote><pre>
 525 keyserver pool.sks-keyservers.net
 526 </pre></blockquote></p>
 527
 528 <p>With GnuPG version 2 one can also locate the keyserver using SRV
 529 entries in DNS.  Just for fun, I did just that at work, so now every
 530 user of GnuPG at the University of Oslo should find a OpenGPG
 531 keyserver automatically should their need it:</p>
 532
 533 <p><blockquote><pre>
 534 % host -t srv _pgpkey-http._tcp.uio.no
 535 _pgpkey-http._tcp.uio.no has SRV record 0 100 11371 pool.sks-keyservers.net.
 536 %
 537 </pre></blockquote></p>
 538
 539 <p>Now if only
 540 <a href="http://ietfreport.isoc.org/idref/draft-shaw-openpgp-hkp/">the
 541 HKP lookup protocol</a> supported finding signature paths, I would be
 542 very happy.  It can look up a given key or search for a user ID, but I
 543 normally do not want that, but to find a trust path from my key to
 544 another key.  Given a user ID or key ID, I would like to find (and
 545 download) the keys representing a signature path from my key to the
 546 key in question, to be able to get a trust path between the two keys.
 547 This is as far as I can tell not possible today.  Perhaps something
 548 for a future version of the protocol?</p>

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

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

 847       <div class="date">31st July 2014</div>
 848       <div class="body"><p>The complete and free “out of the box” software solution for
 849 schools, <a href="http://www.skolelinux.org/">Debian Edu /
 850 Skolelinux</a>, is used quite a lot in Germany, and one of the people
 851 involved is Bernd Zeitzen, who show up on the project mailing lists
 852 from time to time with interesting questions and tips on how to adjust
 853 the setup.  I managed to interview him this summer.</p>
 854
 855 <p><strong>Who are you, and how do you spend your days?</strong></p>
 856
 857 <p>My name is Bernd Zeitzen and I'm married with Hedda, a self
 858 employed physiotherapist.  My former profession is tool maker, but I
 859 haven't worked for 30 years in this job.  30 years ago I started to
 860 support my wife and become her officeworker and a few years later the
 861 administrator for a small computer network, today based on Ubuntu
 862 Server (Samba, OpenVPN). For her daily work she has to use Windows
 863 Desktops because the software she needs to organize her business only
 864 works with Windows . :-(</p>
 865
 866 <p>In 1988 we started with one PC and DOS, then I learned to use
 867 Windows 98, 2000, XP, …, 8, Ubuntu, MacOSX.  Today we are running a
 868 Linux server with 6 Windows clients and 10 persons (teacher of
 869 children with special needs, speech therapist, occupational therapist,
 870 psychologist and officeworkers) using our Samba shares via OpenVPN to
 871 work with the documentations of our patients.</p>
 872
 873 <p><strong>How did you get in contact with the Skolelinux / Debian Edu
 874 project?</strong></p>
 875
 876 <p>Two years ago a friend of mine asked me, if I want to get a job in
 877 his school (<a href="http://www.gymnasium-harsewinkel.de/">Gymnasium
 878 Harsewinkel</a>).  They started with Skolelinux / Debian Edu and they
 879 were looking for people to give support to the teachers using the
 880 software and the network and teaching the pupils increasing their
 881 computer skills in optional lessons.  I'm spending 4-6 hours a week
 882 with this job.</p>
 883
 884 <p><strong>What do you see as the advantages of Skolelinux / Debian
 885 Edu?</strong></p>
 886
 887 <p>The independence.</p>
 888
 889 <p>First: Every person is allowed to use, share and develop the
 890 software. Even if you are poor, you are allowed to use the software
 891 included in Skolelinux/Debian Edu and all the other Free Software.</p>
 892
 893 <p>Second: The software runs on old machines and this gives us the
 894 possibility to recycle computers, weeded out from offices.  The
 895 servers and desktops are running for more than two years and they are
 896 working reliable. </p>
 897
 898 <p>We have two servers (one tjener and one terminal server), 45
 899 workstations in three classrooms and seven laptops as a mobile
 900 solution for all classrooms.  These machines are all booting from the
 901 terminal server.  In the moment we are installing 30 laptops as mobile
 902 workstations.  Then the pupils have the possibility to work with these
 903 machines in their classrooms.  Internet access is realized by a WLAN
 904 router, connected to the schools network. This is all done without a
 905 dedicated system administrator or a computer science teacher.</p>
 906
 907 <p><strong>What do you see as the disadvantages of Skolelinux / Debian
 908 Edu?</strong></p>
 909
 910 <p>Teachers and pupils are Windows users.  &lt;Irony on&gt; And Linux
 911 isn't cool. It's software for freaks using the command line. &lt;Irony
 912 off&gt; They don't realize the stability of the system. </p>
 913
 914 <p><strong>Which free software do you use daily?</strong></p>
 915
 916 <p>Firefox, Thunderbird, LibreOffice, Ubuntu Server 12.04 (Samba,
 917 Apache, MySQL, Joomla!, … and Skolelinux / Debian Edu)</p>
 918
 919 <p><strong>Which strategy do you believe is the right one to use to
 920 get schools to use free software?</strong></p>
 921
 922 <p>In Germany we have the situation: every school is free to decide
 923 which software they want to use. This decision is influenced by
 924 teachers who learned to use Windows and MS Office. They buy a PC with
 925 Windows preinstalled and an additional testing version of MS
 926 Office. They don't know about the possibility to use Free Software
 927 instead.  Another problem are the publisher of school books.  They
 928 develop their software, added to the school books, for Windows.</p>

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

 982       <div class="date">17th June 2014</div>
 983       <div class="body"><p>The <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux
 984 project</a> provide an instruction manual for teachers, system
 985 administrators and other users that contain useful tips for setting up
 986 and maintaining a Debian Edu installation.  This text is about how the
 987 text processing of this manual is handled in the project.</p>
 988
 989 <p>One goal of the project is to provide information in the native
 990 language of its users, and for this we need to handle translations.
 991 But we also want to make sure each language contain the same
 992 information, so for this we need a good way to keep the translations
 993 in sync.  And we want it to be easy for our users to improve the
 994 documentation, avoiding the need to learn special formats or tools to
 995 contribute, and the obvious way to do this is to make it possible to
 996 edit the documentation using a web browser.  We also want it to be
 997 easy for translators to keep the translation up to date, and give them
 998 help in figuring out what need to be translated. Here is the list of
 999 tools and the process we have found trying to reach all these
1000 goals.</p>
1001
1002 <p>We maintain the authoritative source of our manual in the
1003 <a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/">Debian
1004 wiki</a>, as several wiki pages written in English.  It consist of one
1005 front page with references to the different chapters, several pages
1006 for each chapter, and finally one "collection page" gluing all the
1007 chapters together into one large web page (aka
1008 <a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/AllInOne">the
1009 AllInOne page</a>).  The AllInOne page is the one used for further
1010 processing and translations.  Thanks to the fact that the
1011 <a href="http://moinmo.in/">MoinMoin</a> installation on
1012 wiki.debian.org support exporting pages in
1013 <a href="http://www.docbook.org/">the Docbook format</a>, we can fetch
1014 the list of pages to export using the raw version of the AllInOne
1015 page, loop over each of them to generate a Docbook XML version of the
1016 manual.  This process also download images and transform image
1017 references to use the locally downloaded images.  The generated
1018 Docbook XML files are slightly broken, so some post-processing is done
1019 using the <tt>documentation/scripts/get_manual</tt> program, and the
1020 result is a nice Docbook XML file (debian-edu-wheezy-manual.xml) and
1021 a handfull of images.  The XML file can now be used to generate PDF, HTML
1022 and epub versions of the English manual.  This is the basic step of
1023 our process, making PDF (using dblatex), HTML (using xsltproc) and
1024 epub (using dbtoepub) version from Docbook XML, and the resulting files
1025 are placed in the debian-edu-doc-en binary package.</p>
1026
1027 <p>But English documentation is not enough for us.  We want translated
1028 documentation too, and we want to make it easy for translators to
1029 track the English original.  For this we use the
1030 <a href="http://packages.qa.debian.org/p/poxml.html">poxml</a> package,
1031 which allow us to transform the English Docbook XML file into a
1032 translation file (a .pot file), usable with the normal gettext based
1033 translation tools used by those translating free software.  The pot
1034 file is used to create and maintain translation files (several .po
1035 files), which the translations update with the native language
1036 translations of all titles, paragraphs and blocks of text in the
1037 original.  The next step is combining the original English Docbook XML
1038 and the translation file (say debian-edu-wheezy-manual.nb.po), to
1039 create a translated Docbook XML file (in this case
1040 debian-edu-wheezy-manual.nb.xml).  This translated (or partly
1041 translated, if the translation is not complete) Docbook XML file can
1042 then be used like the original to create a PDF, HTML and epub version
1043 of the documentation.</p>
1044
1045 <p>The translators use different tools to edit the .po files.  We
1046 recommend using
1047 <a href="http://www.kde.org/applications/development/lokalize/">lokalize</a>,
1048 while some use emacs and vi, others can use web based editors like
1049 <a href="http://pootle.translatehouse.org/">Poodle</a> or
1050 <a href="https://www.transifex.com/">Transifex</a>.  All we care about
1051 is where the .po file end up, in our git repository.  Updated
1052 translations can either be committed directly to git, or submitted as
1053 <a href="https://bugs.debian.org/src:debian-edu-doc">bug reports
1054 against the debian-edu-doc package</a>.</p>
1055
1056 <p>One challenge is images, which both might need to be translated (if
1057 they show translated user applications), and are needed in different
1058 formats when creating PDF and HTML versions (epub is a HTML version in
1059 this regard).  For this we transform the original PNG images to the
1060 needed density and format during build, and have a way to provide
1061 translated images by storing translated versions in
1062 images/$LANGUAGECODE/.  I am a bit unsure about the details here.  The
1063 package maintainers know more.</p>
1064
1065 <p>If you wonder what the result look like, we provide
1066 <a href="http://maintainer.skolelinux.org/debian-edu-doc/">the content
1067 of the documentation packages on the web</a>.  See for example the
1068 <a href="http://maintainer.skolelinux.org/debian-edu-doc/it/debian-edu-wheezy-manual.pdf">Italian
1069 PDF version</a> or the
1070 <a href="http://maintainer.skolelinux.org/debian-edu-doc/de/debian-edu-wheezy-manual.html">German
1071 HTML version</a>.  We do not yet build the epub version by default,
1072 but perhaps it will be done in the future.</p>

1152       <div class="date">29th May 2014</div>
1153       <div class="body"><p>Dear lazyweb.  I'm planning to set up a small Raspberry Pi computer
1154 in my car, connected to
1155 <a href="http://www.dx.com/p/400a-4-0-tft-lcd-digital-monitor-for-vehicle-parking-reverse-camera-1440x272-12v-dc-57776">a
1156 small screen</a> next to the rear mirror.  I plan to hook it up with a
1157 GPS and a USB wifi card too.  The idea is to get my own
1158 "<a href="http://en.wikipedia.org/wiki/Carputer">Carputer</a>".  But I
1159 wonder if someone already created a good free software solution for
1160 such car computer.</p>
1161
1162 <p>This is my current wish list for such system:</p>
1163
1164 <ul>
1165
1166  <li>Work on Raspberry Pi.</li>
1167
1168  <li>Show current speed limit based on location, and warn if going too
1169    fast (for example using color codes yellow and red on the screen,
1170    or make a sound).  This could be done either using either data from
1171    <a href="http://www.openstreetmap.org/">Openstreetmap</a> or OCR
1172    info gathered from a dashboard camera.</li>
1173
1174  <li>Track automatic toll road passes and their cost, show total spent
1175    and make it possible to calculate toll costs for planned
1176    route.</li>
1177
1178  <li>Collect GPX tracks for use with OpenStreetMap.</li>
1179
1180  <li>Automatically detect and use any wireless connection to connect
1181    to home server.  Try IP over DNS
1182    (<a href="http://dev.kryo.se/iodine/">iodine</a>) or ICMP
1183    (<a href="http://code.gerade.org/hans/">Hans</a>) if direct
1184    connection do not work.</li>
1185
1186  <li>Set up mesh network to talk to other cars with the same system,
1187    or some standard car mesh protocol.</li>
1188
1189  <li>Warn when approaching speed cameras and speed camera ranges
1190    (speed calculated between two cameras).</li>
1191
1192  <li>Suport dashboard/front facing camera to discover speed limits and
1193    run OCR to track registration number of passing cars.</li>
1194
1195 </ul>
1196
1197 <p>If you know of any free software car computer system supporting
1198 some or all of these features, please let me know.</p>
