  24       <div class="date"> 7th March 2014</div>
  25       <div class="body"><p>For noen uker siden ble NXCs fri programvarelisenserte
  26 NOARK5-løsning
  27 <a href="http://www.nuug.no/aktiviteter/20140211-noark/">presentert hos
  28 NUUG</a> (video
  29 <a href="https://www.youtube.com/watch?v=JCb_dNS3MHQ">på youtube
  30 foreløbig</a>), og det fikk meg til å titte litt mer på NOARK5,
  31 standarden for arkivhåndtering i det offentlige Norge.  Jeg lurer på
  32 om denne kjernen kan være nyttig i et par av mine prosjekter, og for ett
  33 av dem er det mest aktuelt å lagre epost.  Jeg klarte ikke finne noen
  34 anbefaling om hvordan RFC 822-formattert epost (aka Internett-epost)
  35 burde lagres i NOARK5, selv om jeg vet at noen arkiver tar
  36 PDF-utskrift av eposten med sitt epostprogram og så arkiverer PDF-en
  37 (eller enda værre, tar papirutskrift og lagrer bildet av eposten som
  38 PDF i arkivet).</p>
  39
  40 <p>Det er ikke så mange formater som er akseptert av riksarkivet til
  41 langtidsoppbevaring av offentlige arkiver, og PDF og XML er de mest
  42 aktuelle i så måte.  Det slo meg at det måtte da finnes en eller annen
  43 egnet XML-representasjon og at det kanskje var enighet om hvilken som
  44 burde brukes, så jeg tok mot til meg og spurte
  45 <a href="http://samdok.com/">SAMDOK</a>, en gruppe tilknyttet
  46 arkivverket som ser ut til å jobbe med NOARK-samhandling, om de hadde
  47 noen anbefalinger:
  48
  49 <p><blockquote>
  50 <p>Hei.</p>
  51
  52 <p>Usikker på om dette er riktig forum å ta opp mitt spørsmål, men jeg
  53 lurer på om det er definert en anbefaling om hvordan RFC
  54 822-formatterte epost (aka vanlig Internet-epost) bør lages håndteres
  55 i NOARK5, slik at en bevarer all informasjon i eposten
  56 (f.eks. Received-linjer).  Finnes det en anbefalt XML-mapping ala den
  57 som beskrives på
  58 &lt;URL: <a href="https://www.informit.com/articles/article.aspx?p=32074">https://www.informit.com/articles/article.aspx?p=32074</a> &gt;?  Mitt
  59 mål er at det skal være mulig å lagre eposten i en NOARK5-kjerne og
  60 kunne få ut en identisk formattert kopi av opprinnelig epost ved
  61 behov.</p>
  62 </blockquote></p>
  63
  64 <p>Postmottaker hos SAMDOK mente spørsmålet heller burde stilles
  65 direkte til riksarkivet, og jeg fikk i dag svar derfra formulert av
  66 seniorrådgiver Geir Ivar Tungesvik:</p>
  67
  68 <p><blockquote>
  69 <p>Riksarkivet har ingen anbefalinger når det gjelder konvertering fra
  70 e-post til XML.  Det står arkivskaper fritt å eventuelt definere/bruke
  71 eget format.  Inklusive da - som det spørres om - et format der det er
  72 mulig å re-etablere e-post format ut fra XML-en.  XML (e-post)
  73 dokumenter må være referert i arkivstrukturen, og det må vedlegges et
  74 gyldig XML skjema (.xsd) for XML-filene. Arkivskaper står altså fritt
  75 til å gjøre hva de vil, bare det dokumenteres og det kan dannes et
  76 utrekk ved avlevering til depot.</p>
  77
  78 <p>De obligatoriske kravene i Noark 5 standarden må altså oppfylles -
  79 etter dialog med Riksarkivet i forbindelse med godkjenning. For
  80 offentlige arkiv er det særlig viktig med filene loependeJournal.xml
  81 og offentligJournal.xml. Private arkiv som vil forholde seg til Noark
  82 5 standarden er selvsagt frie til å bruke det som er relevant for dem
  83 av obligatoriske krav.</p>
  84 </blockquote></p>
  85
  86 <p>Det ser dermed ut for meg som om det er et lite behov for å
  87 standardisere XML-lagring av RFC-822-formatterte meldinger.  Noen som
  88 vet om god spesifikasjon i så måte?  I tillegg til den omtalt over,
  89 har jeg kommte over følgende aktuelle beskrivelser (søk på "rfc 822
  90 xml", så finner du aktuelle alternativer).</p>

 233       <div class="date">22nd February 2014</div>
 234       <div class="body"><p>Many years ago, I wrote a GPL licensed version of the netgroup and
 235 innetgr tools, because I needed them in
 236 <a href="http://www.skolelinux.org/">Skolelinux</a>.  I called the project
 237 ng-utils, and it has served me well.  I placed the project under the
 238 <a href="http://www.hungry.com/">Hungry Programmer</a> umbrella, and it was maintained in our CVS
 239 repository.  But many years ago, the CVS repository was dropped (lost,
 240 not migrated to new hardware, not sure), and the project have lacked a
 241 proper home since then.</p>
 242
 243 <p>Last summer, I had a look at the package and made a new release
 244 fixing a irritating crash bug, but was unable to store the changes in
 245 a proper source control system.  I applied for a project on
 246 <a href="https://alioth.debian.org/">Alioth</a>, but did not have time
 247 to follow up on it.  Until today. :)</p>
 248
 249 <p>After many hours of cleaning and migration, the ng-utils project
 250 now have a new home, and a git repository with the highlight of the
 251 history of the project.  I published all release tarballs and imported
 252 them into the git repository.  As the project is really stable and not
 253 expected to gain new features any time soon, I decided to make a new
 254 release and call it 1.0.  Visit the new project home on
 255 <a href="https://alioth.debian.org/projects/ng-utils/">https://alioth.debian.org/projects/ng-utils/</a>
 256 if you want to check it out.  The new version is also uploaded into

 271       <div class="date"> 3rd February 2014</div>
 272       <div class="body"><p>A few days ago I decided to try to help the Hurd people to get
 273 their changes into sysvinit, to allow them to use the normal sysvinit
 274 boot system instead of their old one.  This follow up on the
 275 <a href="https://teythoon.cryptobitch.de//categories/gsoc.html">great
 276 Google Summer of Code work</a> done last summer by Justus Winter to
 277 get Debian on Hurd working more like Debian on Linux.  To get started,
 278 I downloaded a prebuilt hard disk image from
 279 <a href="http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz">http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz</a>,
 280 and started it using virt-manager.</p>
 281
 282 <p>The first think I had to do after logging in (root without any
 283 password) was to get the network operational.  I followed
 284 <a href="https://www.debian.org/ports/hurd/hurd-install">the
 285 instructions on the Debian GNU/Hurd ports page</a> and ran these
 286 commands as root to get the machine to accept a IP address from the
 287 kvm internal DHCP server:</p>
 288
 289 <p><blockquote><pre>
 290 settrans -fgap /dev/netdde /hurd/netdde
 291 kill $(ps -ef|awk '/[p]finet/ { print $2}')
 292 kill $(ps -ef|awk '/[d]evnode/ { print $2}')
 293 dhclient /dev/eth0
 294 </pre></blockquote></p>
 295
 296 <p>After this, the machine had internet connectivity, and I could
 297 upgrade it and install the sysvinit packages from experimental and
 298 enable it as the default boot system in Hurd.</p>
 299
 300 <p>But before I did that, I set a password on the root user, as ssh is
 301 running on the machine it for ssh login to work a password need to be
 302 set.  Also, note that a bug somewhere in openssh on Hurd block
 303 compression from working.  Remember to turn that off on the client
 304 side.</p>
 305
 306 <p>Run these commands as root to upgrade and test the new sysvinit
 307 stuff:</p>
 308
 309 <p><blockquote><pre>
 310 cat > /etc/apt/sources.list.d/experimental.list &lt;&lt;EOF
 311 deb http://http.debian.net/debian/ experimental main
 312 EOF
 313 apt-get update
 314 apt-get dist-upgrade
 315 apt-get install -t experimental initscripts sysv-rc sysvinit \
 316     sysvinit-core sysvinit-utils
 317 update-alternatives --config runsystem
 318 </pre></blockquote></p>
 319
 320 <p>To reboot after switching boot system, you have to use
 321 <tt>reboot-hurd</tt> instead of just <tt>reboot</tt>, as there is not
 322 yet a sysvinit process able to receive the signals from the normal
 323 'reboot' command.  After switching to sysvinit as the boot system,
 324 upgrading every package and rebooting, the network come up with DHCP
 325 after boot as it should, and the settrans/pkill hack mentioned at the
 326 start is no longer needed.  But for some strange reason, there are no
 327 longer any login prompt in the virtual console, so I logged in using
 328 ssh instead.
 329
 330 <p>Note that there are some race conditions in Hurd making the boot
 331 fail some times.  No idea what the cause is, but hope the Hurd porters
 332 figure it out.  At least Justus said on IRC (#debian-hurd on
 333 irc.debian.org) that they are aware of the problem.  A way to reduce
 334 the impact is to upgrade to the Hurd packages built by Justus by
 335 adding this repository to the machine:</p>
 336
 337 <p><blockquote><pre>
 338 cat > /etc/apt/sources.list.d/hurd-ci.list &lt;&lt;EOF
 339 deb http://darnassus.sceen.net/~teythoon/hurd-ci/ sid main
 340 EOF
 341 </pre></blockquote></p>
 342
 343 <p>At the moment the prebuilt virtual machine get some packages from
 344 http://ftp.debian-ports.org/debian, because some of the packages in
 345 unstable do not yet include the required patches that are lingering in
 346 BTS.  This is the completely list of "unofficial" packages installed:</p>
 347

 368 <p>All in all, testing hurd has been an interesting experience. :)
 369 X.org did not work out of the box and I never took the time to follow
 370 the porters instructions to fix it.  This time I was interested in the

 385       <div class="date">29th January 2014</div>
 386       <div class="body"><p>Bitcoin is a incredible use of peer to peer communication and
 387 encryption, allowing direct and immediate money transfer without any
 388 central control.  It is sometimes claimed to be ideal for illegal
 389 activity, which I believe is quite a long way from the truth.  At least
 390 I would not conduct illegal money transfers using a system where the
 391 details of every transaction are kept forever.  This point is
 392 investigated in
 393 <a href="https://www.usenix.org/publications/login">USENIX ;login:</a>
 394 from December 2013, in the article
 395 "<a href="https://www.usenix.org/system/files/login/articles/03_meiklejohn-online.pdf">A
 396 Fistful of Bitcoins - Characterizing Payments Among Men with No
 397 Names</a>" by Sarah Meiklejohn, Marjori Pomarole,Grant Jordan, Kirill
 398 Levchenko, Damon McCoy, Geoffrey M. Voelker, and Stefan Savage.  They
 399 analyse the transaction log in the Bitcoin system, using it to find
 400 addresses belong to individuals and organisations and follow the flow
 401 of money from both Bitcoin theft and trades on Silk Road to where the
 402 money end up.  This is how they wrap up their article:</p>
 403
 404 <p><blockquote>
 405 <p>"To demonstrate the usefulness of this type of analysis, we turned
 406 our attention to criminal activity. In the Bitcoin economy, criminal
 407 activity can appear in a number of forms, such as dealing drugs on
 408 Silk Road or simply stealing someone else’s bitcoins. We followed the
 409 flow of bitcoins out of Silk Road (in particular, from one notorious
 410 address) and from a number of highly publicized thefts to see whether
 411 we could track the bitcoins to known services. Although some of the
 412 thieves attempted to use sophisticated mixing techniques (or possibly
 413 mix services) to obscure the flow of bitcoins, for the most part
 414 tracking the bitcoins was quite straightforward, and we ultimately saw
 415 large quantities of bitcoins flow to a variety of exchanges directly
 416 from the point of theft (or the withdrawal from Silk Road).</p>
 417
 418 <p>As acknowledged above, following stolen bitcoins to the point at
 419 which they are deposited into an exchange does not in itself identify
 420 the thief; however, it does enable further de-anonymization in the
 421 case in which certain agencies can determine (through, for example,
 422 subpoena power) the real-world owner of the account into which the
 423 stolen bitcoins were deposited.  Because such exchanges seem to serve
 424 as chokepoints into and out of the Bitcoin economy (i.e., there are
 425 few alternative ways to cash out), we conclude that using Bitcoin for
 426 money laundering or other illicit purposes does not (at least at
 427 present) seem to be particularly attractive."</p>
 428 </blockquote><p>
 429
 430 <p>These researches are not the first to analyse the Bitcoin
 431 transaction log.  The 2011 paper
 432 "<a href="http://arxiv.org/abs/1107.4524">An Analysis of Anonymity in
 433 the Bitcoin System</A>" by Fergal Reid and Martin Harrigan is
 434 summarized like this:</p>
 435
 436 <p><blockquote>
 437 "Anonymity in Bitcoin, a peer-to-peer electronic currency system, is a
 438 complicated issue. Within the system, users are identified by
 439 public-keys only. An attacker wishing to de-anonymize its users will
 440 attempt to construct the one-to-many mapping between users and
 441 public-keys and associate information external to the system with the
 442 users. Bitcoin tries to prevent this attack by storing the mapping of
 443 a user to his or her public-keys on that user's node only and by
 444 allowing each user to generate as many public-keys as required. In
 445 this chapter we consider the topological structure of two networks
 446 derived from Bitcoin's public transaction history. We show that the
 447 two networks have a non-trivial topological structure, provide
 448 complementary views of the Bitcoin system and have implications for
 449 anonymity. We combine these structures with external information and
 450 techniques such as context discovery and flow analysis to investigate
 451 an alleged theft of Bitcoins, which, at the time of the theft, had a
 452 market value of approximately half a million U.S. dollars."
 453 </blockquote></p>
 454
 455 <p>I hope these references can help kill the urban myth that Bitcoin
 456 is anonymous.  It isn't really a good fit for illegal activites.  Use
 457 cash if you need to stay anonymous, at least until regular DNA
 458 sampling of notes and coins become the norm. :)</p>

 460 <p>As usual, if you use Bitcoin and want to show your support of my
 461 activities, please send Bitcoin donations to my address

 477       <div class="body"><p><a href="http://www.coverity.com/">Coverity</a> is a nice tool to
 478 find problems in C, C++ and Java code using static source code
 479 analysis.  It can detect a lot of different problems, and is very
 480 useful to find memory and locking bugs in the error handling part of
 481 the source.  The company behind it provide
 482 <a href="https://scan.coverity.com/">check of free software projects as
 483 a community service</a>, and many hundred free software projects are
 484 already checked.  A few days ago I decided to have a closer look at
 485 the Coverity system, and discovered that the
 486 <a href="http://www.gnu.org/software/gnash/">gnash</a> and
 487 <a href="http://sourceforge.net/projects/ipmitool/">ipmitool</a>
 488 projects I am involved with was already registered.  But these are
 489 fairly big, and I would also like to have a small and easy project to
 490 check, and decided to <a href="http://scan.coverity.com/projects/1179">request
 491 checking of the chrpath project</a>.  It was
 492 added to the checker and discovered seven potential defects.  Six of
 493 these were real, mostly resource "leak" when the program detected an
 494 error.  Nothing serious, as the resources would be released a fraction
 495 of a second later when the program exited because of the error, but it
 496 is nice to do it right in case the source of the program some time in
 497 the future end up in a library.  Having fixed all defects and added
 498 <a href="https://lists.alioth.debian.org/mailman/listinfo/chrpath-devel">a
 499 mailing list for the chrpath developers</a>, I decided it was time to
 500 publish a new release.  These are the release notes:</p>

 502 <p>New in 0.16 released 2014-01-14:</p>
 503
 504 <ul>

 532       <div class="body"><p>The <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux
 533 project</a> consist of both newcomers and old timers, and this time I
 534 was able to get an interview with a newcomer in the project who showed
 535 up on the IRC channel a few weeks ago to let us know about his
 536 successful installation of Debian Edu Wheezy in his School.  Say hello
 537 to <a href="https://www.ohloh.net/accounts/Natureshadow">Dominik
 538 George</a>.</p>
 539
 540 <!-- http://www.dominik-george.de/images/foto.jpg -->
 541
 542 <p><strong>Who are you, and how do you spend your days?</strong></p>
 543
 544 <p>I am a 23 year-old student from Germany who has spent half of his
 545 life with open source. In "real life", I am, as already mentioned, a
 546 student in the fields of Computer Science, Electrical Engineering,
 547 Information Technologies and Anglistics. Due to my (only partially
 548 voluntary) huge engagement in the open source world, these things are
 549 a bit vacant right now however.</p>
 550
 551 <p>I also have been working as a project teacher at a Gymasnium
 552 (public school) for various years now. I took up that work some time
 553 around 2005 when still attending that school myself and have continued
 554 it until today. I also had been running the (kind of very advanced)
 555 network of that school together with a team of very interested and
 556 talented students in the age of 11 to 15 years, who took the chance to
 557 learn a lot about open source and networking before I left the school
 558 to help building another school's informational education concept from
 559 scratch.</p>
 560
 561 <p>That said, one might see me as a kind of "glue" between school kids
 562 and the elderly of teachers as well as between the open source
 563 ecosystem and the (even more complex) educational ecosystem.</p>
 564
 565 <p>When I am not busy with open source or education, I like Geocaching
 566 and cycling.</p>
 567
 568 <p><strong>How did you get in contact with the Skolelinux / Debian Edu
 569 project?</strong></p>
 570
 571 <p>I think that happened some time around 2009 when I first attended
 572 <a href="http://www.froscon.org">FrOSCon</a> and visited the project
 573 booth. I think I wasn't too interested back then because I used to
 574 have an attitude of disliking software that does too much stuff on its
 575 own. Maybe I was too inexperienced to realise the upsides of an
 576 "out-of-the-box" solution ;).</p>
 577
 578 <p>The first time I actively talked to Skolelinux people was at
 579 <a href="http://www.openrheinruhr.de">OpenRheinRuhr</a> 2011 when the
 580 BiscuIT project, a home-grewn software used by my school for various
 581 really cool things from timetables and class contact lists to lunch
 582 ordering, student ID card printing and project elections first got to
 583 a stage where it could have been published. I asked the Skolelinux
 584 guys running the booth if the project were interested in it and gave a
 585 small demonstration, but there wasn't any real feedback and the guys
 586 seemed rather uninterested.</p>
 587
 588 <p>After I left the school where I developed the software, it got
 589 mostly lost, but I am now reimplementing it for my new school. I have
 590 reusability and compatibility in mind, and I hop there will be a new
 591 basis for contributing it to the Skolelinux project ;)!</p>
 592
 593 <p><strong>What do you see as the advantages of Skolelinux / Debian
 594 Edu?</strong></p>
 595
 596 <p>The most important advantage seems to be that it "just
 597 works". After overcoming some minor (but still very annoying) glitches
 598 in the installer, I got a fully functional, working school network,
 599 without the month-long hassle I experienced when setting all that up
 600 from scratch in earlier years. And above that, it rocked - I didn't
 601 have any real hardware at hand, because the school was just founded
 602 and has no money whatsoever, so I installed a combined server (main
 603 server, terminal services and workstation) in a VM on my personal
 604 notebook, bridging the LTSP network interface to the ethernet port,
 605 and then PXE-booted the Windows notebooks that were lying around from
 606 it. I could use 8 clients without any performance issues, by using a
 607 tiny little VM on a tiny little notebook. I think that's enough to say
 608 that it rocks!</p>
 609
 610 <p>Secondly, there are marketing reasons. Life's bad, and so no
 611 politician will ever permit a setup described as "Debian, an universal
 612 operating system, with some really cool educational tools" while they
 613 will be jsut fine with "Skolelinux, a single-purpose solution for your
 614 school network", even if both turn out to be the very same thing (yes,
 615 this is unfair towards the Skolelinux project, and must not be taken
 616 too seriously - you get the idea, anyway).</p>
 617
 618 <p><strong>What do you see as the disadvantages of Skolelinux / Debian
 619 Edu?</strong></p>
 620
 621 <p>I have not been involved with Skolelinux long enough to really
 622 answer this question in a fair way. Thus, please allow me to put it in
 623 other words: "What do you expect from Skolelinux to keep liking it?" I
 624 can list a few points about that:</p>
 625
 626 <ul>
 627
 628  <li>always strive to get all things integrated into Debian upstream
 629  <li>be open to discussion about changes and the like, even with newcomers
 630  <li>be helpful at being helpful ;)
 631
 632 </ul>
 633
 634 <p>I'm really sorry I cannot say much more about that :(!</p>
 635
 636 <p><strong>Which free software do you use daily?</strong></p>
 637
 638 <p>First of all, all software I use is free and open. I have abandoned
 639 all non-free software (except for firmware on my darned phone) this
 640 year.</p>
 641
 642 <p>I run Debian GNU/Linux on all PC systems I use. On that, I mostly
 643 run text tools. I use
 644 <a href="https://www.mirbsd.org/mksh.htm">mksh</a> as shell,
 645 <a href="https://www.mirbsd.org/jupp.htm">jupp</a> as very advanced
 646 text editor (I even got the developer to help me write a script/macro
 647 based full-featured student management software with the two),
 648 <a href="http://mcabber.com/">mcabber</a> for XMPP and
 649 <a href="http://www.irssi.org/">irssi</a> for IRC. For that overly
 650 coloured world called the WWW, I use
 651 <a href="https://www.mozilla.org/en-US/firefox/new/">Iceweasel
 652 (Firefox)</a>. Oh, and <a href="http://www.mutt.org/">mutt</a> for
 653 e-mail.</p>
 654
 655 <p>However, while I am personally aware of the fact that text tools
 656 are more efficient and powerful than anything else, I also use (or at
 657 least operate) some tools that are suitable to bring open source to
 658 kids. One of these things is <a href="http://jappix.org/">Jappix</a>,
 659 which I already introduced to some kids even before they got aware of
 660 Facebook, making them see for themselves that they do not need
 661 Facebook now ;).</p>
 662
 663 <p><strong>Which strategy do you believe is the right one to use to
 664 get schools to use free software?</strong></p>
 665
 666 <p>Well, that's a two-sided thing. One side is what I believe, and one
 667 side is what I have experienced.</p>
 668
 669 <p>I believe that the right strategy is showing them the benefits. But
 670 that won't work out as long as the acceptance of free alternatives
 671 grows globally. What I mean is that if all the kids are almost forced
 672 to use Windows, Facebook, Skype, you name it at home, they will not
 673 see why they would want to use alternatives at school. I have seen
 674 students take seat in front of a fully-functional, modern Debian
 675 desktop that could do anything their Windows at home could do, and
 676 they jsut refused to use it because "Linux sucks". It is something
 677 that makes the council of our city spend around 600000 € to buy
 678 software - not including hardware, mind you - for operating school
 679 networks, and for installing a system that, as has been proved, does
 680 not work. For those of you readers who are good at maths, have you
 681 already found out how many lives could have been saved with that money
 682 if we had instead used it to bring education to parts of the world
 683 that need it? I have, and found it to be nothing less dramatic than
 684 plain criminal.</p>
 685
 686 <p>That said, the only feasible way appears to be the bottom up
 687 method. We have to bring free software to kids and parents. I have
 688 founded an association named
 689 <a href="https://www.teckids.org">Teckids</a> here in Germany that does
 690 just that. We organise several events for kids and adolescents in the
 691 area of free and open source software, for example the
 692 <a href="http://kids.froscon.org">FrogLabs</a>, which share staff with
 693 Teckids and are the youth programme of
 694 <a href="http://www.froscon.org">the Free and Open Source Software
 695 Conference (FrOSCon)</a>. We do a lot more than most other conferences
 696 - this year, we first offered the FrogLabs as a holiday camp for kids
 697 aged 10 to 16. It was a huge success, with approx. 30 kids taking part
 698 and learning with and about free software through a whole weekend. All
 699 of us had a lot of fun, and the results were really exciting.</p>
 700
 701 <p>Apart from that, we are preparing a campaign that is supposed to bring
 702 the message of free alternatives to stuff kids use every day to them and
 703 their parents, e.g. the use of Jabber / Jappix instead of Facebook and
 704 Skype. To make that possible, we are planning to get together a team of
 705 clever kids who understand very well what their peers need and can bring
 706 it across to them. So we will have a peer-driven network of adolescents
 707 who teach each other and collect feedback from the community of minors.
 708 We then take that feedback and our own experience to work closely with
 709 open source projects, such as Skolelinux or Jappix, at improving their
 710 software in a way that makes it more and more attractive for the target
 711 group. At least I hope that we will have good cooperation with
 712 Skolelinux in the future ;)!</p>
 713
 714 <p>So in conclusion, what I believe is that, if it weren't for the world
 715 being so bad, it should be very clear to the political decision makers
 716 that the only way to go nowadays is free software for various reasons,
 717 but I have learnt that the only way that seems to work is bottom up.</p>
 718
 719 <!--
 720
 721 >  * Who should be interviewed with this questions in the future?
 722
 723 That's probably the hardest question of them all, as I do not know the
 724 community. However, I would be willing to do the following:
 725
 726  <li>Run an interview with a German headteacher who is very open to
 727    free software, and also prefers it, but cannot really use it because
 728    of the decision makers above;
 729  <li>Run interviews with some kids, both with and without previous
 730    knowledge about free software
 731
 732 If that is wanted, just let me know ;).

 751 Faire</a>, og <a href="http://www.dugnadsnett.no/">Dugnadsnett for
 752 alle</a> har fått plass!  Planen er å ha et bord med en plakat der vi
 753 forteller om hva Dugnadsnett for alle er for noe, og et lite verksted
 754 der vi hjelper folk som er interessert i å få opp sin egen mesh-node.
 755 Jeg gleder meg til å se hvordan prosjektet blir mottatt der.</p>
 756
 757 <p>Målet med dugnadsnett for alle i Oslo er å få på plass et datanett
 758 for kommunikasjon ved hjelp av radio-repeaterstasjoner (kalt
 759 mesh-noder) som gjør at en kan direkte kommunisere med slekt, venner
 760 og bekjente i Oslo via andre som deltar i dugnadsnettet, samt gjøre
 761 det mulig komme ut på internett via dugnadsnettet.  Første delmål er å
 762 kunne sende SMS-meldinger vha. IP-telefoni løsningen
 763 <a href="http://www.servalproject.org/">Serval project</a> mellom
 764 deltagerne i Dugnadsnett for alle i Oslo.  Formålet er å ta tilbake
 765 kontrollen over egen nett-infrastruktur og gjøre det dyrere å bedrive
 766 massiv innsamling av informasjon om borgernes bruk av datanett.</p>
 767
 768 <p>Høres dette interessant ut?  Bli med på prosjektet, fortell oss
 769 hvor du kunne tenke deg å sette opp en radio-repeater (slik at folk i
 770 nærheten kan finne hverandre ved hjelp av
 771 <a href="http://flynor.net/mesh/mesh.php">kartet over planlagte og
 772 eksisterende radio-repeatere</A>), bli med på epostlisten

 775 <a href="irc://irc.freenode.net/#dugnadsnett.no">IRC-kanalen
 776 #dugnadsnett.no</a>.  Så langt er det planlagt over 40
 777 radio-repeatere, med VPN-forbindelser via Internet for å la de delene
 778 av nettet som ikke når hverandre via radio kunne snakke med hverandre
 779 likevel.</p>

 793       <div class="date"> 6th December 2013</div>
 794       <div class="body"><p>It has been a while since I managed to publish the last interview,
 795 but the <a href="http://www.skolelinux.org/">Debian Edu /
 796 Skolelinux</a> community is still going strong, and yesterday we even
 797 had a new school administrator show up on
 798 <a href="irc://irc.debian.org/#debian-edu">#debian-edu</a> to share
 799 his success story with installing Debian Edu at their school.  This
 800 time I have been able to get some helpful comments from the creator of
 801 Knoppix, Klaus Knopper, who was involved in a Skolelinux project in
 802 Germany a few years ago.</p>
 803
 804 <p><strong>Who are you, and how do you spend your days?</strong></p>
 805
 806 <p>I am Klaus Knopper.  I have a master degree in electrical
 807 engineering, and is currently professor in information management at
 808 the university of applied sciences Kaiserslautern / Germany and
 809 freelance Open Source software developer and consultant.</p>
 810
 811 <p>All of this is pretty much of the work I spend my days with. Apart
 812 from teaching, I'm also conducting some more or less experimental
 813 projects like the <a href="http://www.knoppix.org">Knoppix GNU/Linux live
 814 system</a> (Debian-based like Skolelinux),
 815 <a href="http://www.knopper.net/knoppix-adriane/index-en.html">ADRIANE</a>
 816 (a blind-friendly talking desktop system) and
 817 <a href="http://www.knopper.net/linbo/index-en.html">LINBO</a>
 818 (Linux-based network boot console, a fast remote install and repair
 819 system supporting various operating systems).</p>
 820
 821 <p><strong>How did you get in contact with the Skolelinux / Debian Edu
 822 project?</strong></p>
 823
 824 <p>The credit for this have to go to Kurt Gramlich, who is the German
 825 coordinator for Skolelinux.  We were looking for an all-in-one open
 826 source community-supported distribution for schools, and Kurt
 827 introduced us to Skolelinux for this purpose.</p>
 828
 829 <p><strong>What do you see as the advantages of Skolelinux / Debian
 830 Edu?</strong></p>
 831
 832 <ul>
 833   <li>Quick installation,</li>
 834   <li>works (almost) out of the box,</li>
 835   <li>contains many useful software packages for teaching and learning,</li>
 836   <li>is a purely community-based distro and not controlled by a
 837     single company,</li>
 838   <li>has a large number of supporters and teachers who share their
 839     experience and problem solutions.</li>
 840 </ul>
 841
 842 <p><strong>What do you see as the disadvantages of Skolelinux / Debian
 843 Edu?</strong></p>
 844
 845 <ul>
 846   <li>Skolelinux is - as we had to learn - not easily upgradable to
 847   the next version.  Opposed to its genuine Debian base, upgrading to
 848   a new version means a full new installation from scratch to get it
 849   working again reliably.
 850
 851   <li>Skolelinux is based on Debian/stable, and therefore always a
 852   little outdated in terms of program versions compared to Edubuntu or
 853   similar educational Linux distros, which rather use Debian/testing
 854   as their base.
 855
 856   <li>Skolelinux has some very self-opinionated and stubborn default
 857   configuration which in my opinion adds unnecessary complexity and is
 858   not always suitable for a schools needs, the preset network
 859   configuration is actually a core definition feature of Skolelinux
 860   and not easy to change, so schools sometimes have to change their
 861   network configuration to make it "Skolelinux-compatible".
 862
 863   <li>Some proposed extensions, which were made available as
 864   contribution, like secure examination mode and lecture material
 865   distribution and collection, were not accepted into the mainline
 866   Skolelinux development and are now not easy to maintain in the
 867   future because of Skolelinux somewhat undeterministic update
 868   schemes.</li>
 869
 870   <li>Skolelinux has only a very tiny number of base developers
 871   compared to Debian.</li>
 872
 873 </ul>
 874
 875 <p>For these reasons and experience from our project, I would now
 876 rather consider using plain Debian for schools next time, until
 877 Skolelinux is more closely integrated into Debian and becomes
 878 upgradeable without reinstallation.</p>
 879
 880 <p><strong>Which free software do you use daily?</strong></p>
 881
 882 <p>GNU/Linux with LXDE desktop, bash for interactive dialog and
 883 programming, texlive for documentation and correspondence,
 884 occasionally LibreOffice for document format conversion. Various
 885 programming languages for teaching.</p>
 886
 887 <p><strong>Which strategy do you believe is the right one to use to
 888 get schools to use free software?</strong></p>
 889
 890 <p>Strong arguments are</p>
 891
 892 <ul>
 893
 894   <li>Knowledge is free, and so should be methods and tools for
 895     teaching and learning.</li>
 896
 897   <li>Students can learn with and use the same software at school, at
 898     home, and at their working place without running into license or
 899     conversion problems.</li>
 900
 901   <li>Closed source or proprietary software hides knowledge rather
 902     than exposing it, and proprietary software vendors try to bind
 903     customers to certain products.  But teachers need to teach
 904     science, not products.</li>
 905
 906   <li>If you have everything you for daily work as open source, what
 907     would you need proprietary software for?</li>
 908
 909 </ul>

 924       <div class="body"><p>If you want the ability to electronically communicate directly with
 925 your neighbors and friends using a network controlled by your peers in
 926 stead of centrally controlled by a few corporations, or would like to
 927 experiment with interesting network technology, the
 928 <a href="http://www.dugnadsnett.no/">Dugnasnett for alle i Oslo</a>
 929 might be project for you.  39 mesh nodes are currently being planned,
 930 in the freshly started initiative from NUUG and Hackeriet to create a
 931 wireless community network.  The work is inspired by
 932 <a href="http://freifunk.net/">Freifunk</a>,
 933 <a href="http://www.awmn.net/">Athens Wireless Metropolitan
 934 Network</a>, <a href="http://en.wikipedia.org/wiki/Roofnet">Roofnet</a>
 935 and other successful mesh networks around the globe.  Two days ago we
 936 held a workshop to try to get people started on setting up their own
 937 mesh node, and there we decided to create a new mailing list
 938 <a href="http://lists.nuug.no/mailman/listinfo/dugnadsnett">dugnadsnett
 939 (at) nuug.no</a> and IRC channel
 940 <a href="irc://irc.freenode.net/#dugnadsnett.no">#dugnadsnett.no</a> to
 941 coordinate the work.  See also the NUUG blog post
