  74       <div class="date">26th September 2014</div>
  75       <div class="body"><p>The <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux
  76 project</a> provide a Linux solution for schools, including a
  77 powerful desktop with education software, a central server providing
  78 web pages, user database, user home directories, central login and PXE
  79 boot of both  clients without disk and the installation to install Debian
  80 Edu on machines with disk (and a few other services perhaps to small
  81 to mention here).  We in the Debian Edu team are currently working on
  82 the Jessie based version, trying to get everything in shape before the
  83 freeze, to avoid having to maintain our own package repository in the
  84 future.  The
  85 <a href="https://wiki.debian.org/DebianEdu/Status/Jessie">current
  86 status</a> can be seen on the Debian wiki, and there is still heaps of
  87 work left.  Some fatal problems block testing, breaking the installer,
  88 but it is possible to work around these to get anyway.  Here is a
  89 recipe on how to get the installation limping along.</p>
  90
  91 <p>First, download the test ISO via
  92 <a href="ftp://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso">ftp</a>,
  93 <a href="http://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso">http</a>
  94 or rsync (use
  95 ftp.skolelinux.org::cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso).
  96 The ISO build was broken on Tuesday, so we do not get a new ISO every
  97 12 hours or so, but thankfully the ISO we already got we are able to
  98 install with some tweaking.</p>
  99
 100 <p>When you get to the Debian Edu profile question, go to tty2
 101 (use Alt-Ctrl-F2), run</p>
 102
 103 <p><blockquote><pre>
 104 nano /usr/bin/edu-eatmydata-install
 105 </pre></blockquote></p>
 106
 107 <p>and add 'exit 0' as the second line, disabling the eatmydata
 108 optimization.  Return to the installation, select the profile you want
 109 and continue.  Without this change, exim4-config will fail to install
 110 due to a known bug in eatmydata.</p>
 111
 112 <p>When you get the grub question at the end, answer /dev/sda (or if
 113 this do not work, figure out what your correct value would be.  All my
 114 test machines need /dev/sda, so I have no advice if it do not fit
 115 your need.</p>
 116
 117 <p>If you installed a profile including a graphical desktop, log in as
 118 root after the initial boot from hard drive, and install the
 119 education-desktop-XXX metapackage.  XXX can be kde, gnome, lxde, xfce
 120 or mate.  If you want several desktop options, install more than one
 121 metapackage.  Once this is done, reboot and you should have a working
 122 graphical login screen.  This workaround should no longer be needed
 123 once the education-tasks package version 1.801 enter testing in two
 124 days.</p>
 125
 126 <p>I believe the ISO build will start working on two days when the new
 127 tasksel package enter testing and Steve McIntyre get a chance to
 128 update the debian-cd git repository.  The eatmydata, grub and desktop
 129 issues are already fixed in unstable and testing, and should show up
 130 on the ISO as soon as the ISO build start working again.  Well the
 131 eatmydata optimization is really just disabled.  The proper fix
 132 require an upload by the eatmydata maintainer applying the patch
 133 provided in bug <a href="https://bugs.debian.org/702711">#702711</a>.
 134 The rest have proper fixes in unstable.</p>
 135
 136 <p>I hope this get you going with the installation testing, as we are
 137 quickly running out of time trying to get our Jessie based
 138 installation ready before the distribution freeze in a month.</p>

 152       <div class="date">25th September 2014</div>
 153       <div class="body"><p>I use the <a href="https://sourceforge.net/p/lsdvd/">lsdvd tool</a>
 154 to handle my fairly large DVD collection.  It is a nice command line
 155 tool to get details about a DVD, like title, tracks, track length,
 156 etc, in XML, Perl or human readable format.  But lsdvd have not seen
 157 any new development since 2006 and had a few irritating bugs affecting
 158 its use with some DVDs.  Upstream seemed to be dead, and in January I
 159 sent a small probe asking for a version control repository for the
 160 project, without any reply.  But I use it regularly and would like to
 161 get <a href="https://packages.qa.debian.org/lsdvd">an updated version
 162 into Debian</a>.  So two weeks ago I tried harder to get in touch with
 163 the project admin, and after getting a reply from him explaining that
 164 he was no longer interested in the project, I asked if I could take
 165 over.  And yesterday, I became project admin.</p>
 166
 167 <p>I've been in touch with a Gentoo developer and the Debian
 168 maintainer interested in joining forces to maintain the upstream
 169 project, and I hope we can get a new release out fairly quickly,
 170 collecting the patches spread around on the internet into on place.
 171 I've added the relevant Debian patches to the freshly created git
 172 repository, and expect the Gentoo patches to make it too.  If you got
 173 a DVD collection and care about command line tools, check out
 174 <a href="https://sourceforge.net/p/lsdvd/git/ci/master/tree/">the git source</a> and join
 175 <a href="https://sourceforge.net/p/lsdvd/mailman/">the project mailing
 176 list</a>. :)</p>

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

 200
 201 <p>Boksen er tydelig merket «Kapsch >>>», logoen til
 202 <a href="http://www.kapsch.net/">det sveitsiske selskapet Kapsch</a> som
 203 blant annet lager sensorsystemer for veitrafikk.  Men de lager mye
 204 forskjellig, og jeg kjente ikke igjen boksen på utseendet etter en
 205 kjapp titt på produktlista til selskapet.</p>
 206
 207 <p>I og med at boksen henger over veien E16, en riksvei vedlikeholdt
 208 av Statens Vegvesen, så antok jeg at det burde være mulig å bruke
 209 REST-API-et som gir tilgang til vegvesenets database over veier,
 210 skilter og annet veirelatert til å finne ut hva i alle dager dette
 211 kunne være.  De har både
 212 <a href="https://www.vegvesen.no/nvdb/api/dokumentasjon/datakatalog">en
 213 datakatalog</a> og
 214 <a href="https://www.vegvesen.no/nvdb/api/dokumentasjon/sok">et
 215 søk</a>, der en kan søke etter ulike typer oppføringer innen for et
 216 gitt geografisk område.  Jeg laget et enkelt shell-script for å hente
 217 ut antall av en gitt type innenfor området skibrua dekker, og listet
 218 opp navnet på typene som ble funnet.  Orket ikke slå opp hvordan
 219 URL-koding av aktuelle strenger kunne gjøres mer generisk, og brukte
 220 en stygg sed-linje i stedet.</p>

 393 <p>Av disse ser ID 775 og 862 mest relevant ut.  ID 775 antar jeg
 394 refererer til fotoboksen som står like ved brua, mens
 395 «Reisetidsregistreringspunkt» kanskje kan være boksen som henger der.
 396 Hvordan finner jeg så ut hva dette kan være for noe.  En titt på
 397 <a href="http://labs.vegdata.no/nvdb-datakatalog/862-Reisetidsregistreringspunkt/">datakatalogsiden
 398 for ID 862/Reisetidsregistreringspunkt</a> viser at det er finnes 53
 399 slike målere i Norge, og hvor de er plassert, men gir ellers få
 400 detaljer.  Det er plassert 40 på østlandet og 13 i Trondheimsregionen.
 401 Men siden nevner «AutoPASS», og hvis en slår opp oppføringen på
 402 Sollihøgda nevner den «Ciber AS» som ID for eksternt system.  (Kan det
 403 være snakk om
 404 <a href="http://www.proff.no/selskap/ciber-norge-as/oslo/internettdesign-og-programmering/Z0I3KMF4/">Ciber
 405 Norge AS</a>, et selskap eid av Ciber Europe Bv?)  Et nettsøk på
 406  «Ciber AS autopass» fører meg til en artikkel fra NRK Trøndelag i

 414 for Østlandet</a> som viser at det måles mellom Sandvika og Sollihøgda.
 415 Det kan dermed se ut til at jeg har funnet ut hva boksene gjør.</p>
 416
 417 <p>Hvis det stemmer, så er dette bokser som leser av AutoPASS-ID-en
 418 til alle passerende biler med AutoPASS-brikke, og dermed gjør det mulig
 419 for de som kontrollerer boksene å holde rede på hvor en gitt bil er
 420 når den passerte et slikt målepunkt.  NRK-artikkelen forteller at
 421 denne informasjonen i dag kun brukes til å koble to
 422 AutoPASS-brikkepasseringer passeringer sammen for å beregne
 423 reisetiden, og at bruken er godkjent av Datatilsynet.  Det er desverre
 424 ikke mulig for en sjåfør som passerer under en slik boks å kontrollere
 425 at AutoPASS-ID-en kun brukes til dette i dag og i fremtiden.</p>
 426
 427 <p>I tillegg til denne type AutoPASS-sniffere vet jeg at det også
 428 finnes mange automatiske stasjoner som tar betalt pr. passering (aka
 429 bomstasjoner), og der lagres informasjon om tid, sted og bilnummer i
 430 10 år.  Finnes det andre slike sniffere plassert ut på veiene?</p>
 431
 432 <p>Personlig har jeg valgt å ikke bruke AutoPASS-brikke, for å gjøre
 433 det vanskeligere og mer kostbart for de som vil invadere privatsfæren
 434 og holde rede på hvor bilen min beveger seg til enhver tid.  Jeg håper
 435 flere vil gjøre det samme, selv om det gir litt høyere private
 436 utgifter (dyrere bompassering).  Vern om privatsfæren koster i disse
 437 dager.</p>

 454       <div class="date">16th September 2014</div>
 455       <div class="body"><p>The <a href="https://www.debian.org/">Debian</a> installer could be
 456 a lot quicker.  When we install more than 2000 packages in
 457 <a href="http://www.skolelinux.org/">Skolelinux / Debian Edu</a> using
 458 tasksel in the installer, unpacking the binary packages take forever.
 459 A part of the slow I/O issue was discussed in
 460 <a href="https://bugs.debian.org/613428">bug #613428</a> about too
 461 much file system sync-ing done by dpkg, which is the package
 462 responsible for unpacking the binary packages.  Other parts (like code
 463 executed by postinst scripts) might also sync to disk during
 464 installation.  All this sync-ing to disk do not really make sense to
 465 me.  If the machine crash half-way through, I start over, I do not try
 466 to salvage the half installed system.  So the failure sync-ing is
 467 supposed to protect against, hardware or system crash, is not really
 468 relevant while the installer is running.</p>
 469
 470 <p>A few days ago, I thought of a way to get rid of all the file
 471 system sync()-ing in a fairly non-intrusive way, without the need to
 472 change the code in several packages.  The idea is not new, but I have
 473 not heard anyone propose the approach using dpkg-divert before.  It
 474 depend on the small and clever package
 475 <a href="https://packages.qa.debian.org/eatmydata">eatmydata</a>, which
 476 uses LD_PRELOAD to replace the system functions for syncing data to
 477 disk with functions doing nothing, thus allowing programs to live
 478 dangerous while speeding up disk I/O significantly.  Instead of
 479 modifying the implementation of dpkg, apt and tasksel (which are the
 480 packages responsible for selecting, fetching and installing packages),
 481 it occurred to me that we could just divert the programs away, replace
 482 them with a simple shell wrapper calling
 483 "eatmydata&nbsp;$program&nbsp;$@", to get the same effect.
 484 Two days ago I decided to test the idea, and wrapped up a simple
 485 implementation for the Debian Edu udeb.</p>
 486
 487 <p>The effect was stunning.  In my first test it reduced the running
 488 time of the pkgsel step (installing tasks) from 64 to less than 44
 489 minutes (20 minutes shaved off the installation) on an old Dell
 490 Latitude D505 machine.  I am not quite sure what the optimised time
 491 would have been, as I messed up the testing a bit, causing the debconf
 492 priority to get low enough for two questions to pop up during
 493 installation.  As soon as I saw the questions I moved the installation
 494 along, but do not know how long the question were holding up the
 495 installation.  I did some more measurements using Debian Edu Jessie,
 496 and got these results.  The time measured is the time stamp in
 497 /var/log/syslog between the "pkgsel: starting tasksel" and the
 498 "pkgsel: finishing up" lines, if you want to do the same measurement
 499 yourself.  In Debian Edu, the tasksel dialog do not show up, and the
 500 timing thus do not depend on how quickly the user handle the tasksel
 501 dialog.</p>

 548
 549 <p>The test is done using a netinst ISO on a USB stick, so some of the
 550 time is spent downloading packages.  The connection to the Internet
 551 was 100Mbit/s during testing, so downloading should not be a
 552 significant factor in the measurement.  Download typically took a few
 553 seconds to a few minutes, depending on the amount of packages being
 554 installed.</p>
 555
 556 <p>The speedup is implemented by using two hooks in
 557 <a href="https://www.debian.org/devel/debian-installer/">Debian
 558 Installer</a>, the pre-pkgsel.d hook to set up the diverts, and the
 559 finish-install.d hook to remove the divert at the end of the
 560 installation.  I picked the pre-pkgsel.d hook instead of the
 561 post-base-installer.d hook because I test using an ISO without the
 562 eatmydata package included, and the post-base-installer.d hook in
 563 Debian Edu can only operate on packages included in the ISO.  The
 564 negative effect of this is that I am unable to activate this
 565 optimization for the kernel installation step in d-i.  If the code is
 566 moved to the post-base-installer.d hook, the speedup would be larger
 567 for the entire installation.</p>
 568
 569 <p>I've implemented this in the
 570 <a href="https://packages.qa.debian.org/debian-edu-install">debian-edu-install</a>
 571 git repository, and plan to provide the optimization as part of the
 572 Debian Edu installation.  If you want to test this yourself, you can
 573 create two files in the installer (or in an udeb).  One shell script
 574 need do go into /usr/lib/pre-pkgsel.d/, with content like this:</p>
 575
 576 <p><blockquote><pre>
 577 #!/bin/sh
 578 set -e
 579 . /usr/share/debconf/confmodule
 580 info() {
 581     logger -t my-pkgsel "info: $*"
 582 }
 583 error() {
 584     logger -t my-pkgsel "error: $*"
 585 }
 586 override_install() {
 587     apt-install eatmydata || true
 588     if [ -x /target/usr/bin/eatmydata ] ; then
 589         for bin in dpkg apt-get aptitude tasksel ; do
 590             file=/usr/bin/$bin
 591             # Test that the file exist and have not been diverted already.
 592             if [ -f /target$file ] ; then
 593                 info "diverting $file using eatmydata"
 594                 printf "#!/bin/sh\neatmydata $bin.distrib \"\$@\"\n" \
 595                     > /target$file.edu
 596                 chmod 755 /target$file.edu
 597                 in-target dpkg-divert --package debian-edu-config \
 598                     --rename --quiet --add $file
 599                 ln -sf ./$bin.edu /target$file
 600             else
 601                 error "unable to divert $file, as it is missing."
 602             fi
 603         done
 604     else
 605         error "unable to find /usr/bin/eatmydata after installing the eatmydata pacage"
 606     fi
 607 }
 608
 609 override_install
 610 </pre></blockquote></p>
 611
 612 <p>To clean up, another shell script should go into
 613 /usr/lib/finish-install.d/ with code like this:
 614
 615 <p><blockquote><pre>
 616 #! /bin/sh -e
 617 . /usr/share/debconf/confmodule
 618 error() {
 619     logger -t my-finish-install "error: $@"
 620 }
 621 remove_install_override() {
 622     for bin in dpkg apt-get aptitude tasksel ; do
 623         file=/usr/bin/$bin
 624         if [ -x /target$file.edu ] ; then
 625             rm /target$file
 626             in-target dpkg-divert --package debian-edu-config \
 627                 --rename --quiet --remove $file
 628             rm /target$file.edu
 629         else
 630             error "Missing divert for $file."
 631         fi
 632     done
 633     sync # Flush file buffers before continuing
 634 }
 635
 636 remove_install_override
 637 </pre></blockquote></p>
 638
 639 <p>In Debian Edu, I placed both code fragments in a separate script
 640 edu-eatmydata-install and call it from the pre-pkgsel.d and
 641 finish-install.d scripts.</p>
 642
 643 <p>By now you might ask if this change should get into the normal
 644 Debian installer too?  I suspect it should, but am not sure the
 645 current debian-installer coordinators find it useful enough.  It also
 646 depend on the side effects of the change.  I'm not aware of any, but I
 647 guess we will see if the change is safe after some more testing.
 648 Perhaps there is some package in Debian depending on sync() and
 649 fsync() having effect?  Perhaps it should go into its own udeb, to
 650 allow those of us wanting to enable it to do so without affecting
 651 everyone.</p>
 652
 653 <p>Update 2014-09-24: Since a few days ago, enabling this optimization
 654 will break installation of all programs using gnutls because of
 655 <a href="https://bugs.debian.org/702711">bug #702711.  An updated
 656 eatmydata package in Debian will solve it.</p>

 670       <div class="date">10th September 2014</div>
 671       <div class="body"><p>Yesterday, I had the pleasure of attending a talk with the
 672 <a href="http://www.nuug.no/">Norwegian Unix User Group</a> about
 673 <a href="http://www.nuug.no/aktiviteter/20140909-sks-keyservers/">the
 674 OpenPGP keyserver pool sks-keyservers.net</a>, and was very happy to
 675 learn that there is a large set of publicly available key servers to
 676 use when looking for peoples public key.  So far I have used
 677 subkeys.pgp.net, and some times wwwkeys.nl.pgp.net when the former
 678 were misbehaving, but those days are ended.  The servers I have used
 679 up until yesterday have been slow and some times unavailable.  I hope
 680 those problems are gone now.</p>
 681
 682 <p>Behind the round robin DNS entry of the
 683 <a href="https://sks-keyservers.net/">sks-keyservers.net</a> service
 684 there is a pool of more than 100 keyservers which are checked every
 685 day to ensure they are well connected and up to date.  It must be
 686 better than what I have used so far. :)</p>
 687
 688 <p>Yesterdays speaker told me that the service is the default
 689 keyserver provided by the default configuration in GnuPG, but this do
 690 not seem to be used in Debian.  Perhaps it should?</p>
 691
 692 <p>Anyway, I've updated my ~/.gnupg/options file to now include this
 693 line:</p>
 694
 695 <p><blockquote><pre>
 696 keyserver pool.sks-keyservers.net
 697 </pre></blockquote></p>
 698
 699 <p>With GnuPG version 2 one can also locate the keyserver using SRV
 700 entries in DNS.  Just for fun, I did just that at work, so now every
 701 user of GnuPG at the University of Oslo should find a OpenGPG
 702 keyserver automatically should their need it:</p>
 703
 704 <p><blockquote><pre>
 705 % host -t srv _pgpkey-http._tcp.uio.no
 706 _pgpkey-http._tcp.uio.no has SRV record 0 100 11371 pool.sks-keyservers.net.
 707 %
 708 </pre></blockquote></p>
 709
 710 <p>Now if only
 711 <a href="http://ietfreport.isoc.org/idref/draft-shaw-openpgp-hkp/">the
 712 HKP lookup protocol</a> supported finding signature paths, I would be
 713 very happy.  It can look up a given key or search for a user ID, but I
 714 normally do not want that, but to find a trust path from my key to
 715 another key.  Given a user ID or key ID, I would like to find (and
 716 download) the keys representing a signature path from my key to the
 717 key in question, to be able to get a trust path between the two keys.
 718 This is as far as I can tell not possible today.  Perhaps something
 719 for a future version of the protocol?</p>

1018       <div class="date">31st July 2014</div>
1019       <div class="body"><p>The complete and free “out of the box” software solution for
1020 schools, <a href="http://www.skolelinux.org/">Debian Edu /
1021 Skolelinux</a>, is used quite a lot in Germany, and one of the people
1022 involved is Bernd Zeitzen, who show up on the project mailing lists
1023 from time to time with interesting questions and tips on how to adjust
1024 the setup.  I managed to interview him this summer.</p>
1025
1026 <p><strong>Who are you, and how do you spend your days?</strong></p>
1027
1028 <p>My name is Bernd Zeitzen and I'm married with Hedda, a self
1029 employed physiotherapist.  My former profession is tool maker, but I
1030 haven't worked for 30 years in this job.  30 years ago I started to
1031 support my wife and become her officeworker and a few years later the
1032 administrator for a small computer network, today based on Ubuntu
1033 Server (Samba, OpenVPN). For her daily work she has to use Windows
1034 Desktops because the software she needs to organize her business only
1035 works with Windows . :-(</p>
1036
1037 <p>In 1988 we started with one PC and DOS, then I learned to use
1038 Windows 98, 2000, XP, …, 8, Ubuntu, MacOSX.  Today we are running a
1039 Linux server with 6 Windows clients and 10 persons (teacher of
1040 children with special needs, speech therapist, occupational therapist,
1041 psychologist and officeworkers) using our Samba shares via OpenVPN to
1042 work with the documentations of our patients.</p>
1043
1044 <p><strong>How did you get in contact with the Skolelinux / Debian Edu
1045 project?</strong></p>
1046
1047 <p>Two years ago a friend of mine asked me, if I want to get a job in
1048 his school (<a href="http://www.gymnasium-harsewinkel.de/">Gymnasium
1049 Harsewinkel</a>).  They started with Skolelinux / Debian Edu and they
1050 were looking for people to give support to the teachers using the
1051 software and the network and teaching the pupils increasing their
1052 computer skills in optional lessons.  I'm spending 4-6 hours a week
1053 with this job.</p>
1054
1055 <p><strong>What do you see as the advantages of Skolelinux / Debian
1056 Edu?</strong></p>
1057
1058 <p>The independence.</p>
1059
1060 <p>First: Every person is allowed to use, share and develop the
1061 software. Even if you are poor, you are allowed to use the software
1062 included in Skolelinux/Debian Edu and all the other Free Software.</p>
1063
1064 <p>Second: The software runs on old machines and this gives us the
1065 possibility to recycle computers, weeded out from offices.  The
1066 servers and desktops are running for more than two years and they are
1067 working reliable. </p>
1068
1069 <p>We have two servers (one tjener and one terminal server), 45
1070 workstations in three classrooms and seven laptops as a mobile
1071 solution for all classrooms.  These machines are all booting from the
1072 terminal server.  In the moment we are installing 30 laptops as mobile
1073 workstations.  Then the pupils have the possibility to work with these
1074 machines in their classrooms.  Internet access is realized by a WLAN
1075 router, connected to the schools network. This is all done without a
1076 dedicated system administrator or a computer science teacher.</p>
1077
1078 <p><strong>What do you see as the disadvantages of Skolelinux / Debian
1079 Edu?</strong></p>
1080
1081 <p>Teachers and pupils are Windows users.  &lt;Irony on&gt; And Linux
1082 isn't cool. It's software for freaks using the command line. &lt;Irony
1083 off&gt; They don't realize the stability of the system. </p>
1084
1085 <p><strong>Which free software do you use daily?</strong></p>
1086
1087 <p>Firefox, Thunderbird, LibreOffice, Ubuntu Server 12.04 (Samba,
1088 Apache, MySQL, Joomla!, … and Skolelinux / Debian Edu)</p>
1089
1090 <p><strong>Which strategy do you believe is the right one to use to
1091 get schools to use free software?</strong></p>
1092
1093 <p>In Germany we have the situation: every school is free to decide
1094 which software they want to use. This decision is influenced by
1095 teachers who learned to use Windows and MS Office. They buy a PC with
1096 Windows preinstalled and an additional testing version of MS
1097 Office. They don't know about the possibility to use Free Software
1098 instead.  Another problem are the publisher of school books.  They
1099 develop their software, added to the school books, for Windows.</p>

1114       <div class="body"><p>This summer I finally had time to continue working on the Norwegian
1115 <a href="http://www.docbook.org/">docbook</a> version of the 2004 book
1116 <a href="http://free-culture.cc/">Free Culture</a> by Lawrence Lessig,
1117 to get a Norwegian text explaining the problems with todays copyright
1118 law.  Yesterday, I finally completed translated the book text.  There
1119 are still some foot/end notes left to translate, the colophon page
1120 need to be rewritten, and a few words and phrases still need to be
1121 translated, but the Norwegian text is ready for the first proof
1122 reading. :) More spell checking is needed, and several illustrations
1123 need to be cleaned up.  The work stopped up because I had to give
1124 priority to other projects the last year, and the progress graph of
1125 the translation show this very well:</p>
