  26 <p><a href="http://www.dagbladet.no/2010/06/16/nyheter/innenriks/streik/arbeidsliv/12157858/">Dagbladet
  27 melder</a> at Vinmonopolet med bakgrunn i vekterstreiken som pågår i
  28 Norge for tiden, har bestemt seg for med vitende og vilje å bryte
  29 sentralbanklovens paragraf 14</a> ved å nekte folk å betale med
  30 kontanter, og at flere butikker planlegger å følge deres eksempel.
  31 Jeg synes det er hårreisende hvis de slipper unna med et slikt
  32 soleklart lovbrudd, og lurer på hva slags muligheter jeg vil ha hvis
  33 jeg blir nektet å handle med kontakter.  Jeg handler i hovedsak med
  34 kontanter selv, da jeg anser det som en borgerrett å kunne handle
  35 anonymt uten at det blir registrert.
  36
  37 <p><a href="http://www.lovdata.no/all/tl-19850524-028-003.html#14">Paragrafen
  38 i sentralbankloven</a> lyder:</p>
  39
  40 <blockquote>
  41 <p>§ 14. Tvungent betalingsmiddel</p>
  42
  43 <p>Bankens sedler og mynter er tvungent betalingsmiddel i Norge. Ingen
  44 er pliktig til i én betaling å ta imot mer enn femogtyve mynter av
  45 hver enhet.
  46
  47 <p>Sterkt skadde sedler og mynter er ikke tvungent
  48 betalingsmiddel. Banken gir nærmere forskrifter om erstatning for
  49 bortkomne, brente eller skadde sedler og mynter.</p>
  50
  51 <p>Selv om en avtale inneholder klausul om betaling av en
  52 pengeforpliktelse i gullverdi, kan skyldneren frigjøre seg med tvungne
  53 betalingsmidler uten hensyn til denne klausul.</p>
  54 </blockquote>
  55
  56 <p>Det er med bakgrunn i denne lovet ikke tillatt å nekte å ta imot
  57 kontakt betaling.  Det er en lov jeg har sans for, og som jeg mener må
  58 håndheves strengt.</p>

  74 <p>For those of us caring about document exchange and
  75 interoperability, <a href="http://www.officeshots.org/">OfficeShots</a>
  76 is a great service.  It is to ODF documents what
  77 <a href="http://browsershots.org/">BrowserShots</a> is for web
  78 pages.</p>
  79
  80 <p>A while back, I was contacted by Knut Yrvin at the part of Nokia
  81 that used to be Trolltech, who wanted to help the OfficeShots project
  82 and wondered if the University of Oslo where I work would be
  83 interested in supporting the project.  I helped him to navigate his
  84 request to the right people at work, and his request was answered with
  85 a spot in the machine room with power and network connected, and Knut
  86 arranged funding for a machine to fill the spot.  The machine is
  87 administrated by the OfficeShots people, so I do not have daily
  88 contact with its progress, and thus from time to time check back to
  89 see how the project is doing.</p>
  90
  91 <p>Today I had a look, and was happy to see that the Dell box in our
  92 machine room now is the host for several virtual machines running as
  93 OfficeShots factories, and the project is able to render ODF documents
  94 in 17 different document processing implementation on Linux and
  95 Windows.  This is great.</p>

 111 <p>My
 112 <a href="http://people.skolelinux.org/pere/blog/Automatic_upgrade_testing_from_Lenny_to_Squeeze.html">testing
 113 of Debian upgrades</a> from Lenny to Squeeze continues, and I've
 114 finally made the upgrade logs available from
 115 <a href="http://people.skolelinux.org/pere/debian-upgrade-testing/">http://people.skolelinux.org/pere/debian-upgrade-testing/</a>.
 116 I am now testing dist-upgrade of Gnome and KDE in a chroot using both
 117 apt and aptitude, and found their differences interesting.  This time
 118 I will only focus on their removal plans.</p>
 119
 120 <p>After installing a Gnome desktop and the laptop task, apt-get wants
 121 to remove 72 packages when dist-upgrading from Lenny to Squeeze.  The
 122 surprising part is that it want to remove xorg and all
 123 xserver-xorg-video* drivers.  Clearly not a good choice, but I am not
 124 sure why.  When asking aptitude to do the same, it want to remove 129
 125 packages, but most of them are library packages I suspect are no
 126 longer needed.  Both of them want to remove bluetooth packages, which
 127 I do not know.  Perhaps these bluetooth packages are obsolete?</p>
 128
 129 <p>For KDE, apt-get want to remove 82 packages, among them kdebase
 130 which seem like a bad idea and xorg the same way as with Gnome. Asking
 131 aptitude for the same, it wants to remove 192 packages, none which are
 132 too surprising.</p>
 133
 134 <p>I guess the removal of xorg during upgrades should be investigated
 135 and avoided, and perhaps others as well.  Here are the complete list
 136 of planned removals.  The complete logs is available from the URL
 137 above.  Note if you want to repeat these tests, that the upgrade test
 138 for kde+apt-get hung in the tasksel setup because of dpkg asking
 139 conffile questions.  No idea why.  I worked around it by using
 140 '<tt>echo >> /proc/<em>pidofdpkg</em>/fd/0</tt>' to tell dpkg to
 141 continue.</p>

 294 <p>Veldig glad for å oppdage via
 295 <a href="http://yro.slashdot.org/story/10/06/11/1841256/Finland-To-Legalize-Use-of-Unsecured-Wi-Fi">Slashdot</a>
 296 at folk i Finland har forstått at åpne trådløsnett er et samfunnsgode.
 297 Jeg ser på åpne trådløsnett som et fellesgode på linje med retten til
 298 ferdsel i utmark og retten til å bevege seg i strandsonen.  Jeg har
 299 glede av åpne trådløsnett når jeg finner dem, og deler gladelig nett
 300 med andre så lenge de ikke forstyrrer min bruk av eget nett.
 301 Nettkapasiteten er sjelden en begrensning ved normal browsing og enkel
 302 SSH-innlogging (som er min vanligste nettbruk), og nett kan brukes til
 303 så mye positivt og nyttig (som nyhetslesing, sjekke været, kontakte
 304 slekt og venner, holde seg oppdatert om politiske saker, kontakte
 305 organisasjoner og politikere, etc), at det for meg er helt urimelig å
 306 blokkere dette for alle som ikke gjør en flue fortred.  De som mener
 307 at potensialet for misbruk er grunn nok til å hindre all den positive
 308 og lovlydige bruken av et åpent trådløsnett har jeg dermed ingen
 309 forståelse for.  En kan ikke eksistensen av forbrytere styre hvordan
 310 samfunnet skal organiseres.  Da får en et kontrollsamfunn de færreste
 311 ønsker å leve i, og det at vi har et samfunn i Norge der tilliten til
 312 hverandre er høy gjør at samfunnet fungerer ganske godt.  Det bør vi
 313 anstrenge oss for å beholde.</p>

 328   <div class="body">
 329 <p>The last few days I have done some upgrade testing in Debian, to
 330 see if the upgrade from Lenny to Squeeze will go smoothly.  A few bugs
 331 have been discovered and reported in the process
 332 (<a href="http://bugs.debian.org/585410">#585410</a> in nagios3-cgi,
 333 <a href="http://bugs.debian.org/584879">#584879</a> already fixed in
 334 enscript and <a href="http://bugs.debian.org/584861">#584861</a> in
 335 kdebase-workspace-data), and to get a more regular testing going on, I
 336 am working on a script to automate the test.</p>
 337
 338 <p>The idea is to create a Lenny chroot and use tasksel to install a
 339 Gnome or KDE desktop installation inside the chroot before upgrading
 340 it.  To ensure no services are started in the chroot, a policy-rc.d
 341 script is inserted.  To make sure tasksel believe it is to install a
 342 desktop on a laptop, the tasksel tests are replaced in the chroot
 343 (only acceptable because this is a throw-away chroot).</p>
 344
 345 <p>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
 346 currently always fail because udev refuses to upgrade with the kernel
 347 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
 348 is created.  The bug report
 349 <a href="http://bugs.debian.org/566000">#566000</a> make me suspect
 350 this problem do not trigger in a chroot, but I touch the file anyway
 351 to make sure the upgrade go well.  Testing on virtual and real
 352 hardware have failed me because of udev so far, and creating this file
 353 do the trick in such settings anyway.  This is a
 354 <a href="http://www.linuxquestions.org/questions/debian-26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-804130/">known
 355 issue</a> and the current udev behaviour is intended by the udev
 356 maintainer because he lack the resources to rewrite udev to keep
 357 working with old kernels or something like that.  I really wish the
 358 udev upstream would keep udev backwards compatible, to avoid such
 359 upgrade problem, but given that they fail to do so, I guess
 360 documenting the way out of this mess is the best option we got for
 361 Debian Squeeze.</p>
 362
 363 <p>Anyway, back to the task at hand, testing upgrades.  This test
 364 script, which I call <tt>upgrade-test</tt> for now, is doing the
 365 trick:</p>
 366
 367 <blockquote><pre>

 425 </pre></blockquote>
 426
 427 <p>I suspect it would be useful to test upgrades with both apt-get and
 428 with aptitude, but I have not had time to look at how they behave
 429 differently so far.  I hope to get a cron job running to do the test
 430 regularly and post the result on the web.  The Gnome upgrade currently
 431 work, while the KDE upgrade fail because of the bug in
 432 kdebase-workspace-data</p>
 433
 434 <p>I am not quite sure what kind of extract from the huge upgrade logs
 435 (KDE 167 KiB, Gnome 516 KiB) it make sense to include in this blog
 436 post, so I will refrain from trying.  I can report that for Gnome,
 437 aptitude report 760 packages upgraded, 448 newly installed, 129 to
 438 remove and 1 not upgraded and 1024MB need to be downloaded while for
 439 KDE the same numbers are 702 packages upgraded, 507 newly installed,
 440 193 to remove and 0 not upgraded and 1117MB need to be downloaded</p>
 441
 442 <p>I am very happy to notice that the Gnome desktop + laptop upgrade
 443 is able to migrate to dependency based boot sequencing and parallel
 444 booting without a hitch.  Was unsure if there were still bugs with
 445 packages failing to clean up their obsolete init.d script during
 446 upgrades, and no such problem seem to affect the Gnome desktop+laptop
 447 packages.</p>

 463 <p>Det er merkelig hvordan myter om Skolelinux overlever.  En slik
 464 myte er at Skolelinux ikke kan sentraldriftes og ha sentralt plasserte
 465 tjenermaskiner.  I siste Computerworld Norge er
 466 <a href="http://www.idg.no/computerworld/article169432.ece">IT-sjef
 467 Viggo Billdal i Steinkjer intervjuet</a>, og forteller uten
 468 blygsel:</p>
 469
 470 <blockquote><p>Vi hadde Skolelinux, men det har vi sluttet med. Vi testet
 471 om det lønte seg med Microsoft eller en åpen plattform. Vi fant ut at
 472 Microsoft egentlig var totalt sett bedre egnet. Det var store
 473 driftskostnader med Skolelinux, blant annet på grunn av
 474 desentraliserte servere. Det var komplisert, så vi gikk vekk fra det
 475 og bruker nå bare Windows.</p></blockquote>
 476
 477 <p>En <a
 478 href="https://init.linpro.no/pipermail/skolelinux.no/bruker/2010-June/009101.html">rask
 479 sjekk</a> mot den norske brukerlista i Skolelinuxprosjektet forteller
 480 at Steinkjers forsøk foregikk fram til 2004/2005, og at Røysing skole
 481 i Steinkjer skal ha vært svært fornøyd med Skolelinux men at kommunen
 482 overkjørte skolen og krevde at de gikk over til Windows.  Et søk på
 483 nettet sendte meg til
 484 <a href="http://www.dn.no/multimedia/archive/00090/Dagens_it_nr__18_90826a.pdf">Dagens
 485 IT nr. 18 2005</a> hvor en kan lese på side 18:</p>
 486
 487 <blockquote><p>Inge Tømmerås ved Røysing skole i Steinkjer kjører ennå
 488 Microsoft, men forteller at kompetanseutfordringen med Skolelinux ikke
 489 var så stor.   Jeg syntes Skolelinux var utrolig lett å drifte uten
 490 forkunnskaper. Men man må jo selvsagt ha tilgang på ekstern kompetanse
 491 til installasjoner og maskinvarefeil, sier Tømmerås.</p></blockquote>
 492
 493 <p>Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
 494 over påstanden om at Skolelinux krever desentraliserte tjenere.
 495 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
 496 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
 497 Den er modellert på nettverks- og tjenerløsningen som brukes på
 498 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
 499 driftstjenester.  Dette er det heldigvis noen som har fått med seg, og
 500 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
 501 artikkelen.  Min venn og gamle kollega Sturle Sunde forteller der:
 502
 503 <blockquote>
 504 <p>I Flora kommune køyrer vi Skulelinux på skular med alt frå 15 til
 505 meir enn 500 elevar. Dei store skulane har eigen tenar, for det er
 506 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
 507 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
 508 avhengige av eksterne linjer som er trege eller dyre. Dei minste
 509 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
 510 noko problem. Småskulane klarar seg fint med 1 mbit-linje til ein
 511 sentral tenar eller tenaren på ein større skule.</p>
 512
 513 <p>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
 514 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
 515 programma lokalt. Eit klasserom med 30 sju-åtte år gamle maskiner har
 516 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
 517 millionen. Det trengst to kommandoar på den sentrale tenaren for å
 518 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
 519 problem med diskar som ryk heller, som var eit problem før fordi
 520 elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
 521 nettet, so det er fullt mogleg å køyre slike på småskular med trege
 522 linjer mot tenaren på ein større skule.</p>
 523
 524 <p>Flora kommune har nesten 800 Linux-maskiner i sitt skulenett, og
 525 ein person som tek seg av drift av heile nettet, inkludert tenarar,
 526 klientar, operativsystem, programvare, heimekontorløysing og
 527 administrasjon av brukarar.</p>
 528
 529 <p>No skal det seiast at vi ikkje køyrer rein Skulelinux ut av
 530 boksen. Vi har gjort ein del tilpassingar mot noko Novell-greier som
 531 var der frå før, og som har komplisert installasjonen vår. Etter at
 532 oppsettet var gjort har løysinga vore stabil og kravd minimalt med
 533 arbeid.</p>
 534 </blockquote>
 535
 536 <p>Jeg vet at Narvik, Harstad og Oslo er kommuner der Skolelinux
 537 sentraldriftes med sentrale tjenere.  Det forteller meg at Steinkjers
 538 IT-sjef neppe bør skylde på Skolelinux-løsningen for sine 5 år gamle
 539 minner.</p>

 554   <div class="body">
 555 <p>If Debian is to migrate to upstart on Linux, I expect some init.d
 556 scripts to migrate (some of) their operations to upstart job while
 557 keeping the init.d for hurd and kfreebsd.  The packages with such
 558 needs will need a way to get their init.d scripts to behave
 559 differently when used with sysvinit and with upstart.  Because of
 560 this, I had a look at the environment variables set when a init.d
 561 script is running under upstart, and when it is not.</p>
 562
 563 <p>With upstart, I notice these environment variables are set when a
 564 script is started from rcS.d/ (ignoring some irrelevant ones like
 565 COLUMNS):</p>
 566
 567 <blockquote><pre>
 568 DEFAULT_RUNLEVEL=2
 569 previous=N
 570 PREVLEVEL=
 571 RUNLEVEL=
 572 runlevel=S
 573 UPSTART_EVENTS=startup
 574 UPSTART_INSTANCE=
 575 UPSTART_JOB=rc-sysinit
 576 </pre></blockquote>
 577
 578 <p>With sysvinit, these environment variables are set for the same
 579 script.</p>
 580
 581 <blockquote><pre>
 582 INIT_VERSION=sysvinit-2.88
 583 previous=N
 584 PREVLEVEL=N
 585 RUNLEVEL=S
 586 runlevel=S
 587 </pre></blockquote>
 588
 589 <p>The RUNLEVEL and PREVLEVEL environment variables passed on from
 590 sysvinit are not set by upstart.  Not sure if it is intentional or not
 591 to not be compatible with sysvinit in this regard.</p>
 592
 593 <p>For scripts needing to behave differently when upstart is used,
 594 looking for the UPSTART_JOB environment variable seem to be a good
 595 choice.</p>

 632 <p>When using sitesummary at a site to track machines, it is possible
 633 to get a list of the machine types in use thanks to the DMI
 634 information extracted from each machine.  The script to do so is
 635 included in the sitesummary package, and here is example output from
 636 the Skolelinux build servers:</p>
 637
 638 <blockquote><pre>
 639 maintainer:~# /usr/lib/sitesummary/hardware-model-summary
 640   vendor                    count
 641   Dell Computer Corporation     1
 642     PowerEdge 1750              1

 647 maintainer:~#
 648 </pre></blockquote>
 649
 650 <p>The quality of the report depend on the quality of the DMI tables
 651 provided in each machine.  Here there are Intel machines without model
 652 information listed with Intel as vendor and mo model, and virtual Xen
 653 machines listed as [no-dmi-info].  One can add -l as a command line
 654 option to list the individual machines.</p>
 655
 656 <p>A larger list is
 657 <a href="http://narvikskolen.no/sitesummary/">available from the the
 658 city of Narvik</a>, which uses Skolelinux on all their shools and also
 659 provide the basic sitesummary report publicly.  In their report there
 660 are ~1400 machines. I know they use both Ubuntu and Skolelinux on
 661 their machines, and as sitesummary is available in both distributions,
 662 it is trivial to get all of them to report to the same central
 663 collector.</p>
