  25       <div class="body"><p>The <a href="https://wiki.debian.org/FreedomBox">Freedombox
  26 project</a> is working on providing the software and hardware for
  27 making it easy for non-technical people to host their data and
  28 communication at home, and being able to communicate with their
  29 friends and family encrypted and away from prying eyes.  It has been
  30 going on for a while, and is slowly progressing towards a new test
  31 release (0.2).</p>
  32
  33 <p>And what day could be better than the Pi day to announce that the
  34 new version will provide "hard drive" / SD card / USB stick images for
  35 Dreamplug, Raspberry Pi and VirtualBox (or any other virtualization
  36 system), and can also be installed using a Debian installer preseed
  37 file.  The Debian based Freedombox is now based on Debian Jessie,
  38 where most of the needed packages used are already present.  Only one,
  39 the freedombox-setup package, is missing.  To try to build your own
  40 boot image to test the current status, fetch the freedom-maker scripts
  41 and build using
  42 <a href="http://packages.qa.debian.org/vmdebootstrap">vmdebootstrap</a>
  43 with a user with sudo access to become root:
  44
  45 <pre>
  46 git clone http://anonscm.debian.org/git/freedombox/freedom-maker.git \
  47   freedom-maker
  48 sudo apt-get install git vmdebootstrap mercurial python-docutils \
  49   mktorrent extlinux virtualbox qemu-user-static binfmt-support \
  50   u-boot-tools
  51 make -C freedom-maker dreamplug-image raspberry-image virtualbox-image
  52 </pre>
  53
  54 <p>Root access is needed to run debootstrap and mount loopback
  55 devices.  See the README for more details on the build. If you do not
  56 want all three images, trim the make line.  But note that thanks to <a
  57 href="https://bugs.debian.org/741407">a race condition in
  58 vmdebootstrap</a>, the build might fail without the patch to the
  59 kpartx call.</p>
  60
  61 <p>If you instead want to install using a Debian CD and the preseed
  62 method, boot a Debian Wheezy ISO and use this boot argument to load
  63 the preseed values:</p>
  64
  65 <pre>
  66 url=<a href="http://www.reinholdtsen.name/freedombox/preseed-jessie.dat">http://www.reinholdtsen.name/freedombox/preseed-jessie.dat</a>
  67 </pre>
  68
  69 <p>But note that due to <a href="https://bugs.debian.org/740673">a
  70 recently introduced bug in apt in Jessie</a>, the installer will
  71 currently hang while setting up APT sources.  Killing the
  72 '<tt>apt-cdrom ident</tt>' process when it hang a few times during the
  73 installation will get the installation going.  This affect all
  74 installations in Jessie, and I expect it will be fixed soon.</p>
  75
  76 Give it a go and let us know how it goes on the mailing list, and help
  77 us get the new release published. :) Please join us on
  78 <a href="irc://irc.debian.org:6667/%23freedombox">IRC (#freedombox on

  95       <div class="date">12th March 2014</div>
  96       <div class="body"><p>On larger sites, it is useful to use a dedicated storage server for
  97 storing user home directories and data.  The design for handling this
  98 in <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>, is
  99 to update the automount rules in LDAP and let the automount daemon on
 100 the clients take care of the rest.  I was reminded about the need to
 101 document this better when one of the customers of
 102 <a href="http://www.slxdrift.no/">Skolelinux Drift AS</a>, where I am
 103 on the board of directors, asked about how to do this.  The steps to
 104 get this working are the following:</p>
 105
 106 <p><ol>
 107
 108 <li>Add new storage server in DNS.  I use nas-server.intern as the
 109 example host here.</li>
 110
 111 <li>Add automoun LDAP information about this server in LDAP, to allow
 112 all clients to automatically mount it on reqeust.</li>
 113
 114 <li>Add the relevant entries in tjener.intern:/etc/fstab, because
 115 tjener.intern do not use automount to avoid mounting loops.</li>
 116
 117 </ol></p>
 118
 119 <p>DNS entries are added in GOsa², and not described here.  Follow the
 120 <a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted">instructions
 121 in the manual</a> (Machine Management with GOsa² in section Getting
 122 started).</p>
 123
 124 <p>Ensure that the NFS export points on the server are exported to the
 125 relevant subnets or machines:</p>
 126
 127 <p><blockquote><pre>
 128 root@tjener:~# showmount -e nas-server
 129 Export list for nas-server:
 130 /storage         10.0.0.0/8
 131 root@tjener:~#
 132 </pre></blockquote></p>
 133
 134 <p>Here everything on the backbone network is granted access to the
 135 /storage export.  With NFSv3 it is slightly better to limit it to
 136 netgroup membership or single IP addresses to have some limits on the
 137 NFS access.</p>
 138
 139 <p>The next step is to update LDAP.  This can not be done using GOsa²,
 140 because it lack a module for automount.  Instead, use ldapvi and add
 141 the required LDAP objects using an editor.</p>
 142
 143 <p><blockquote><pre>
 144 ldapvi --ldap-conf -ZD '(cn=admin)' -b ou=automount,dc=skole,dc=skolelinux,dc=no
 145 </pre></blockquote></p>
 146
 147 <p>When the editor show up, add the following LDAP objects at the
 148 bottom of the document.  The "/&" part in the last LDAP object is a
 149 wild card matching everything the nas-server exports, removing the
 150 need to list individual mount points in LDAP.</p>
 151
 152 <p><blockquote><pre>
 153 add cn=nas-server,ou=auto.skole,ou=automount,dc=skole,dc=skolelinux,dc=no
 154 objectClass: automount
 155 cn: nas-server
 156 automountInformation: -fstype=autofs --timeout=60 ldap:ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
 157
 158 add ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
 159 objectClass: top
 160 objectClass: automountMap
 161 ou: auto.nas-server
 162
 163 add cn=/,ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
 164 objectClass: automount
 165 cn: /
 166 automountInformation: -fstype=nfs,tcp,rsize=32768,wsize=32768,rw,intr,hard,nodev,nosuid,noatime nas-server.intern:/&
 167 </pre></blockquote></p>
 168
 169 <p>The last step to remember is to mount the relevant mount points in
 170 tjener.intern by adding them to /etc/fstab, creating the mount
 171 directories using mkdir and running "mount -a" to mount them.</p>
 172
 173 <p>When this is done, your users should be able to access the files on
 174 the storage server directly by just visiting the
 175 /tjener/nas-server/storage/ directory using any application on any
 176 workstation, LTSP client or LTSP server.</p>

 190       <div class="date"> 7th March 2014</div>
 191       <div class="body"><p>For noen uker siden ble NXCs fri programvarelisenserte
 192 NOARK5-løsning
 193 <a href="http://www.nuug.no/aktiviteter/20140211-noark/">presentert hos
 194 NUUG</a> (video
 195 <a href="https://www.youtube.com/watch?v=JCb_dNS3MHQ">på youtube
 196 foreløbig</a>), og det fikk meg til å titte litt mer på NOARK5,
 197 standarden for arkivhåndtering i det offentlige Norge.  Jeg lurer på
 198 om denne kjernen kan være nyttig i et par av mine prosjekter, og for ett
 199 av dem er det mest aktuelt å lagre epost.  Jeg klarte ikke finne noen
 200 anbefaling om hvordan RFC 822-formattert epost (aka Internett-epost)
 201 burde lagres i NOARK5, selv om jeg vet at noen arkiver tar
 202 PDF-utskrift av eposten med sitt epostprogram og så arkiverer PDF-en
 203 (eller enda værre, tar papirutskrift og lagrer bildet av eposten som
 204 PDF i arkivet).</p>
 205
 206 <p>Det er ikke så mange formater som er akseptert av riksarkivet til
 207 langtidsoppbevaring av offentlige arkiver, og PDF og XML er de mest
 208 aktuelle i så måte.  Det slo meg at det måtte da finnes en eller annen
 209 egnet XML-representasjon og at det kanskje var enighet om hvilken som
 210 burde brukes, så jeg tok mot til meg og spurte
 211 <a href="http://samdok.com/">SAMDOK</a>, en gruppe tilknyttet
 212 arkivverket som ser ut til å jobbe med NOARK-samhandling, om de hadde
 213 noen anbefalinger:
 214
 215 <p><blockquote>
 216 <p>Hei.</p>
 217
 218 <p>Usikker på om dette er riktig forum å ta opp mitt spørsmål, men jeg
 219 lurer på om det er definert en anbefaling om hvordan RFC
 220 822-formatterte epost (aka vanlig Internet-epost) bør lages håndteres
 221 i NOARK5, slik at en bevarer all informasjon i eposten
 222 (f.eks. Received-linjer).  Finnes det en anbefalt XML-mapping ala den
 223 som beskrives på
 224 &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
 225 mål er at det skal være mulig å lagre eposten i en NOARK5-kjerne og
 226 kunne få ut en identisk formattert kopi av opprinnelig epost ved
 227 behov.</p>
 228 </blockquote></p>
 229
 230 <p>Postmottaker hos SAMDOK mente spørsmålet heller burde stilles
 231 direkte til riksarkivet, og jeg fikk i dag svar derfra formulert av
 232 seniorrådgiver Geir Ivar Tungesvik:</p>
 233
 234 <p><blockquote>
 235 <p>Riksarkivet har ingen anbefalinger når det gjelder konvertering fra
 236 e-post til XML.  Det står arkivskaper fritt å eventuelt definere/bruke
 237 eget format.  Inklusive da - som det spørres om - et format der det er
 238 mulig å re-etablere e-post format ut fra XML-en.  XML (e-post)
 239 dokumenter må være referert i arkivstrukturen, og det må vedlegges et
 240 gyldig XML skjema (.xsd) for XML-filene. Arkivskaper står altså fritt
 241 til å gjøre hva de vil, bare det dokumenteres og det kan dannes et
 242 utrekk ved avlevering til depot.</p>
 243
 244 <p>De obligatoriske kravene i Noark 5 standarden må altså oppfylles -
 245 etter dialog med Riksarkivet i forbindelse med godkjenning. For
 246 offentlige arkiv er det særlig viktig med filene loependeJournal.xml
 247 og offentligJournal.xml. Private arkiv som vil forholde seg til Noark
 248 5 standarden er selvsagt frie til å bruke det som er relevant for dem
 249 av obligatoriske krav.</p>
 250 </blockquote></p>
 251
 252 <p>Det ser dermed ut for meg som om det er et lite behov for å
 253 standardisere XML-lagring av RFC-822-formatterte meldinger.  Noen som
 254 vet om god spesifikasjon i så måte?  I tillegg til den omtalt over,
 255 har jeg kommet over flere aktuelle beskrivelser (søk på "rfc 822
 256 xml", så finner du aktuelle alternativer).</p>

 399       <div class="date">22nd February 2014</div>
 400       <div class="body"><p>Many years ago, I wrote a GPL licensed version of the netgroup and
 401 innetgr tools, because I needed them in
 402 <a href="http://www.skolelinux.org/">Skolelinux</a>.  I called the project
 403 ng-utils, and it has served me well.  I placed the project under the
 404 <a href="http://www.hungry.com/">Hungry Programmer</a> umbrella, and it was maintained in our CVS
 405 repository.  But many years ago, the CVS repository was dropped (lost,
 406 not migrated to new hardware, not sure), and the project have lacked a
 407 proper home since then.</p>
 408
 409 <p>Last summer, I had a look at the package and made a new release
 410 fixing a irritating crash bug, but was unable to store the changes in
 411 a proper source control system.  I applied for a project on
 412 <a href="https://alioth.debian.org/">Alioth</a>, but did not have time
 413 to follow up on it.  Until today. :)</p>
 414
 415 <p>After many hours of cleaning and migration, the ng-utils project
 416 now have a new home, and a git repository with the highlight of the
 417 history of the project.  I published all release tarballs and imported
 418 them into the git repository.  As the project is really stable and not
 419 expected to gain new features any time soon, I decided to make a new
 420 release and call it 1.0.  Visit the new project home on
 421 <a href="https://alioth.debian.org/projects/ng-utils/">https://alioth.debian.org/projects/ng-utils/</a>
 422 if you want to check it out.  The new version is also uploaded into
 423 <a href="http://packages.qa.debian.org/n/ng-utils.html">Debian Unstable</a>.</p>

 437       <div class="date"> 3rd February 2014</div>
 438       <div class="body"><p>A few days ago I decided to try to help the Hurd people to get
 439 their changes into sysvinit, to allow them to use the normal sysvinit
 440 boot system instead of their old one.  This follow up on the
 441 <a href="https://teythoon.cryptobitch.de//categories/gsoc.html">great
 442 Google Summer of Code work</a> done last summer by Justus Winter to
 443 get Debian on Hurd working more like Debian on Linux.  To get started,
 444 I downloaded a prebuilt hard disk image from
 445 <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>,
 446 and started it using virt-manager.</p>
 447
 448 <p>The first think I had to do after logging in (root without any
 449 password) was to get the network operational.  I followed
 450 <a href="https://www.debian.org/ports/hurd/hurd-install">the
 451 instructions on the Debian GNU/Hurd ports page</a> and ran these
 452 commands as root to get the machine to accept a IP address from the
 453 kvm internal DHCP server:</p>
 454
 455 <p><blockquote><pre>
 456 settrans -fgap /dev/netdde /hurd/netdde
 457 kill $(ps -ef|awk '/[p]finet/ { print $2}')
 458 kill $(ps -ef|awk '/[d]evnode/ { print $2}')
 459 dhclient /dev/eth0
 460 </pre></blockquote></p>
 461
 462 <p>After this, the machine had internet connectivity, and I could
 463 upgrade it and install the sysvinit packages from experimental and
 464 enable it as the default boot system in Hurd.</p>
 465
 466 <p>But before I did that, I set a password on the root user, as ssh is
 467 running on the machine it for ssh login to work a password need to be
 468 set.  Also, note that a bug somewhere in openssh on Hurd block
 469 compression from working.  Remember to turn that off on the client
 470 side.</p>
 471
 472 <p>Run these commands as root to upgrade and test the new sysvinit
 473 stuff:</p>
 474
 475 <p><blockquote><pre>
 476 cat > /etc/apt/sources.list.d/experimental.list &lt;&lt;EOF
 477 deb http://http.debian.net/debian/ experimental main
 478 EOF
 479 apt-get update
 480 apt-get dist-upgrade
 481 apt-get install -t experimental initscripts sysv-rc sysvinit \
 482     sysvinit-core sysvinit-utils
 483 update-alternatives --config runsystem
 484 </pre></blockquote></p>
 485
 486 <p>To reboot after switching boot system, you have to use
 487 <tt>reboot-hurd</tt> instead of just <tt>reboot</tt>, as there is not
 488 yet a sysvinit process able to receive the signals from the normal
 489 'reboot' command.  After switching to sysvinit as the boot system,
 490 upgrading every package and rebooting, the network come up with DHCP
 491 after boot as it should, and the settrans/pkill hack mentioned at the
 492 start is no longer needed.  But for some strange reason, there are no
 493 longer any login prompt in the virtual console, so I logged in using
 494 ssh instead.
 495
 496 <p>Note that there are some race conditions in Hurd making the boot
 497 fail some times.  No idea what the cause is, but hope the Hurd porters
 498 figure it out.  At least Justus said on IRC (#debian-hurd on
 499 irc.debian.org) that they are aware of the problem.  A way to reduce
 500 the impact is to upgrade to the Hurd packages built by Justus by
 501 adding this repository to the machine:</p>
 502
 503 <p><blockquote><pre>
 504 cat > /etc/apt/sources.list.d/hurd-ci.list &lt;&lt;EOF
 505 deb http://darnassus.sceen.net/~teythoon/hurd-ci/ sid main
 506 EOF
 507 </pre></blockquote></p>
 508
 509 <p>At the moment the prebuilt virtual machine get some packages from
 510 http://ftp.debian-ports.org/debian, because some of the packages in
 511 unstable do not yet include the required patches that are lingering in
 512 BTS.  This is the completely list of "unofficial" packages installed:</p>
 513
 514 <p><blockquote><pre>
 515 # aptitude search '?narrow(?version(CURRENT),?origin(Debian Ports))'
 516 i   emacs                   - GNU Emacs editor (metapackage)

 532 </pre></blockquote></p>
 533
 534 <p>All in all, testing hurd has been an interesting experience. :)
 535 X.org did not work out of the box and I never took the time to follow
 536 the porters instructions to fix it.  This time I was interested in the
 537 command line stuff.<p>

 551       <div class="date">29th January 2014</div>
 552       <div class="body"><p>Bitcoin is a incredible use of peer to peer communication and
 553 encryption, allowing direct and immediate money transfer without any
 554 central control.  It is sometimes claimed to be ideal for illegal
 555 activity, which I believe is quite a long way from the truth.  At least
 556 I would not conduct illegal money transfers using a system where the
 557 details of every transaction are kept forever.  This point is
 558 investigated in
 559 <a href="https://www.usenix.org/publications/login">USENIX ;login:</a>
 560 from December 2013, in the article
 561 "<a href="https://www.usenix.org/system/files/login/articles/03_meiklejohn-online.pdf">A
 562 Fistful of Bitcoins - Characterizing Payments Among Men with No
 563 Names</a>" by Sarah Meiklejohn, Marjori Pomarole,Grant Jordan, Kirill
 564 Levchenko, Damon McCoy, Geoffrey M. Voelker, and Stefan Savage.  They
 565 analyse the transaction log in the Bitcoin system, using it to find
 566 addresses belong to individuals and organisations and follow the flow
 567 of money from both Bitcoin theft and trades on Silk Road to where the
 568 money end up.  This is how they wrap up their article:</p>
 569
 570 <p><blockquote>
 571 <p>"To demonstrate the usefulness of this type of analysis, we turned
 572 our attention to criminal activity. In the Bitcoin economy, criminal
 573 activity can appear in a number of forms, such as dealing drugs on
 574 Silk Road or simply stealing someone else’s bitcoins. We followed the
 575 flow of bitcoins out of Silk Road (in particular, from one notorious
 576 address) and from a number of highly publicized thefts to see whether
 577 we could track the bitcoins to known services. Although some of the
 578 thieves attempted to use sophisticated mixing techniques (or possibly
 579 mix services) to obscure the flow of bitcoins, for the most part
 580 tracking the bitcoins was quite straightforward, and we ultimately saw
 581 large quantities of bitcoins flow to a variety of exchanges directly
 582 from the point of theft (or the withdrawal from Silk Road).</p>
 583
 584 <p>As acknowledged above, following stolen bitcoins to the point at
 585 which they are deposited into an exchange does not in itself identify
 586 the thief; however, it does enable further de-anonymization in the
 587 case in which certain agencies can determine (through, for example,
 588 subpoena power) the real-world owner of the account into which the
 589 stolen bitcoins were deposited.  Because such exchanges seem to serve
 590 as chokepoints into and out of the Bitcoin economy (i.e., there are
 591 few alternative ways to cash out), we conclude that using Bitcoin for
 592 money laundering or other illicit purposes does not (at least at
 593 present) seem to be particularly attractive."</p>
 594 </blockquote><p>
 595
 596 <p>These researches are not the first to analyse the Bitcoin
 597 transaction log.  The 2011 paper
 598 "<a href="http://arxiv.org/abs/1107.4524">An Analysis of Anonymity in
 599 the Bitcoin System</A>" by Fergal Reid and Martin Harrigan is
 600 summarized like this:</p>
 601
 602 <p><blockquote>
 603 "Anonymity in Bitcoin, a peer-to-peer electronic currency system, is a
 604 complicated issue. Within the system, users are identified by
 605 public-keys only. An attacker wishing to de-anonymize its users will
 606 attempt to construct the one-to-many mapping between users and
 607 public-keys and associate information external to the system with the
 608 users. Bitcoin tries to prevent this attack by storing the mapping of
 609 a user to his or her public-keys on that user's node only and by
 610 allowing each user to generate as many public-keys as required. In
 611 this chapter we consider the topological structure of two networks
 612 derived from Bitcoin's public transaction history. We show that the
 613 two networks have a non-trivial topological structure, provide
 614 complementary views of the Bitcoin system and have implications for
 615 anonymity. We combine these structures with external information and
 616 techniques such as context discovery and flow analysis to investigate
 617 an alleged theft of Bitcoins, which, at the time of the theft, had a
 618 market value of approximately half a million U.S. dollars."
 619 </blockquote></p>
 620
 621 <p>I hope these references can help kill the urban myth that Bitcoin
 622 is anonymous.  It isn't really a good fit for illegal activites.  Use
 623 cash if you need to stay anonymous, at least until regular DNA
 624 sampling of notes and coins become the norm. :)</p>
 625
 626 <p>As usual, if you use Bitcoin and want to show your support of my
 627 activities, please send Bitcoin donations to my address

 643       <div class="body"><p><a href="http://www.coverity.com/">Coverity</a> is a nice tool to
 644 find problems in C, C++ and Java code using static source code
 645 analysis.  It can detect a lot of different problems, and is very
 646 useful to find memory and locking bugs in the error handling part of
 647 the source.  The company behind it provide
 648 <a href="https://scan.coverity.com/">check of free software projects as
 649 a community service</a>, and many hundred free software projects are
 650 already checked.  A few days ago I decided to have a closer look at
 651 the Coverity system, and discovered that the
 652 <a href="http://www.gnu.org/software/gnash/">gnash</a> and
 653 <a href="http://sourceforge.net/projects/ipmitool/">ipmitool</a>
 654 projects I am involved with was already registered.  But these are
 655 fairly big, and I would also like to have a small and easy project to
 656 check, and decided to <a href="http://scan.coverity.com/projects/1179">request
 657 checking of the chrpath project</a>.  It was
 658 added to the checker and discovered seven potential defects.  Six of
 659 these were real, mostly resource "leak" when the program detected an
 660 error.  Nothing serious, as the resources would be released a fraction
 661 of a second later when the program exited because of the error, but it
 662 is nice to do it right in case the source of the program some time in
 663 the future end up in a library.  Having fixed all defects and added
 664 <a href="https://lists.alioth.debian.org/mailman/listinfo/chrpath-devel">a

 699 project</a> consist of both newcomers and old timers, and this time I
 700 was able to get an interview with a newcomer in the project who showed
 701 up on the IRC channel a few weeks ago to let us know about his
 702 successful installation of Debian Edu Wheezy in his School.  Say hello
 703 to <a href="https://www.ohloh.net/accounts/Natureshadow">Dominik
 704 George</a>.</p>
 705
 706 <!-- http://www.dominik-george.de/images/foto.jpg -->
 707
 708 <p><strong>Who are you, and how do you spend your days?</strong></p>
 709
 710 <p>I am a 23 year-old student from Germany who has spent half of his
 711 life with open source. In "real life", I am, as already mentioned, a
 712 student in the fields of Computer Science, Electrical Engineering,
 713 Information Technologies and Anglistics. Due to my (only partially
 714 voluntary) huge engagement in the open source world, these things are
 715 a bit vacant right now however.</p>
 716
 717 <p>I also have been working as a project teacher at a Gymasnium
 718 (public school) for various years now. I took up that work some time
 719 around 2005 when still attending that school myself and have continued
 720 it until today. I also had been running the (kind of very advanced)
 721 network of that school together with a team of very interested and
 722 talented students in the age of 11 to 15 years, who took the chance to
 723 learn a lot about open source and networking before I left the school
 724 to help building another school's informational education concept from
 725 scratch.</p>
 726
 727 <p>That said, one might see me as a kind of "glue" between school kids
 728 and the elderly of teachers as well as between the open source
 729 ecosystem and the (even more complex) educational ecosystem.</p>
 730
 731 <p>When I am not busy with open source or education, I like Geocaching
 732 and cycling.</p>
 733
 734 <p><strong>How did you get in contact with the Skolelinux / Debian Edu
 735 project?</strong></p>
 736
 737 <p>I think that happened some time around 2009 when I first attended
 738 <a href="http://www.froscon.org">FrOSCon</a> and visited the project
 739 booth. I think I wasn't too interested back then because I used to
 740 have an attitude of disliking software that does too much stuff on its
 741 own. Maybe I was too inexperienced to realise the upsides of an
 742 "out-of-the-box" solution ;).</p>
 743
 744 <p>The first time I actively talked to Skolelinux people was at
 745 <a href="http://www.openrheinruhr.de">OpenRheinRuhr</a> 2011 when the
 746 BiscuIT project, a home-grewn software used by my school for various
 747 really cool things from timetables and class contact lists to lunch
 748 ordering, student ID card printing and project elections first got to
 749 a stage where it could have been published. I asked the Skolelinux
 750 guys running the booth if the project were interested in it and gave a
 751 small demonstration, but there wasn't any real feedback and the guys
 752 seemed rather uninterested.</p>
 753
 754 <p>After I left the school where I developed the software, it got
 755 mostly lost, but I am now reimplementing it for my new school. I have
 756 reusability and compatibility in mind, and I hop there will be a new
 757 basis for contributing it to the Skolelinux project ;)!</p>
 758
 759 <p><strong>What do you see as the advantages of Skolelinux / Debian
 760 Edu?</strong></p>
 761
 762 <p>The most important advantage seems to be that it "just
 763 works". After overcoming some minor (but still very annoying) glitches
 764 in the installer, I got a fully functional, working school network,
 765 without the month-long hassle I experienced when setting all that up
 766 from scratch in earlier years. And above that, it rocked - I didn't
 767 have any real hardware at hand, because the school was just founded
 768 and has no money whatsoever, so I installed a combined server (main
 769 server, terminal services and workstation) in a VM on my personal
 770 notebook, bridging the LTSP network interface to the ethernet port,
 771 and then PXE-booted the Windows notebooks that were lying around from
 772 it. I could use 8 clients without any performance issues, by using a
 773 tiny little VM on a tiny little notebook. I think that's enough to say
 774 that it rocks!</p>
 775
 776 <p>Secondly, there are marketing reasons. Life's bad, and so no
 777 politician will ever permit a setup described as "Debian, an universal
 778 operating system, with some really cool educational tools" while they
 779 will be jsut fine with "Skolelinux, a single-purpose solution for your
 780 school network", even if both turn out to be the very same thing (yes,
 781 this is unfair towards the Skolelinux project, and must not be taken
 782 too seriously - you get the idea, anyway).</p>
 783
 784 <p><strong>What do you see as the disadvantages of Skolelinux / Debian
 785 Edu?</strong></p>
 786
 787 <p>I have not been involved with Skolelinux long enough to really
 788 answer this question in a fair way. Thus, please allow me to put it in
 789 other words: "What do you expect from Skolelinux to keep liking it?" I
 790 can list a few points about that:</p>
 791
 792 <ul>
 793
 794  <li>always strive to get all things integrated into Debian upstream
 795  <li>be open to discussion about changes and the like, even with newcomers
 796  <li>be helpful at being helpful ;)
 797
 798 </ul>
 799
 800 <p>I'm really sorry I cannot say much more about that :(!</p>
 801
 802 <p><strong>Which free software do you use daily?</strong></p>
 803
 804 <p>First of all, all software I use is free and open. I have abandoned
 805 all non-free software (except for firmware on my darned phone) this
 806 year.</p>
 807
 808 <p>I run Debian GNU/Linux on all PC systems I use. On that, I mostly
 809 run text tools. I use
 810 <a href="https://www.mirbsd.org/mksh.htm">mksh</a> as shell,
 811 <a href="https://www.mirbsd.org/jupp.htm">jupp</a> as very advanced
 812 text editor (I even got the developer to help me write a script/macro
 813 based full-featured student management software with the two),
 814 <a href="http://mcabber.com/">mcabber</a> for XMPP and
 815 <a href="http://www.irssi.org/">irssi</a> for IRC. For that overly
 816 coloured world called the WWW, I use
 817 <a href="https://www.mozilla.org/en-US/firefox/new/">Iceweasel
 818 (Firefox)</a>. Oh, and <a href="http://www.mutt.org/">mutt</a> for
 819 e-mail.</p>
 820
 821 <p>However, while I am personally aware of the fact that text tools
 822 are more efficient and powerful than anything else, I also use (or at
 823 least operate) some tools that are suitable to bring open source to
 824 kids. One of these things is <a href="http://jappix.org/">Jappix</a>,
 825 which I already introduced to some kids even before they got aware of
 826 Facebook, making them see for themselves that they do not need
 827 Facebook now ;).</p>
 828
 829 <p><strong>Which strategy do you believe is the right one to use to
 830 get schools to use free software?</strong></p>
 831
 832 <p>Well, that's a two-sided thing. One side is what I believe, and one
 833 side is what I have experienced.</p>
 834
 835 <p>I believe that the right strategy is showing them the benefits. But
 836 that won't work out as long as the acceptance of free alternatives
 837 grows globally. What I mean is that if all the kids are almost forced
 838 to use Windows, Facebook, Skype, you name it at home, they will not
 839 see why they would want to use alternatives at school. I have seen
 840 students take seat in front of a fully-functional, modern Debian
 841 desktop that could do anything their Windows at home could do, and
 842 they jsut refused to use it because "Linux sucks". It is something
 843 that makes the council of our city spend around 600000 € to buy
 844 software - not including hardware, mind you - for operating school
 845 networks, and for installing a system that, as has been proved, does
 846 not work. For those of you readers who are good at maths, have you
 847 already found out how many lives could have been saved with that money
 848 if we had instead used it to bring education to parts of the world
 849 that need it? I have, and found it to be nothing less dramatic than
 850 plain criminal.</p>
 851
 852 <p>That said, the only feasible way appears to be the bottom up
 853 method. We have to bring free software to kids and parents. I have
 854 founded an association named
 855 <a href="https://www.teckids.org">Teckids</a> here in Germany that does
 856 just that. We organise several events for kids and adolescents in the
 857 area of free and open source software, for example the
 858 <a href="http://kids.froscon.org">FrogLabs</a>, which share staff with
 859 Teckids and are the youth programme of
 860 <a href="http://www.froscon.org">the Free and Open Source Software
 861 Conference (FrOSCon)</a>. We do a lot more than most other conferences
 862 - this year, we first offered the FrogLabs as a holiday camp for kids
 863 aged 10 to 16. It was a huge success, with approx. 30 kids taking part
 864 and learning with and about free software through a whole weekend. All
 865 of us had a lot of fun, and the results were really exciting.</p>
 866
 867 <p>Apart from that, we are preparing a campaign that is supposed to bring
 868 the message of free alternatives to stuff kids use every day to them and
 869 their parents, e.g. the use of Jabber / Jappix instead of Facebook and
 870 Skype. To make that possible, we are planning to get together a team of
 871 clever kids who understand very well what their peers need and can bring
 872 it across to them. So we will have a peer-driven network of adolescents
 873 who teach each other and collect feedback from the community of minors.
 874 We then take that feedback and our own experience to work closely with
 875 open source projects, such as Skolelinux or Jappix, at improving their
 876 software in a way that makes it more and more attractive for the target
 877 group. At least I hope that we will have good cooperation with
 878 Skolelinux in the future ;)!</p>
 879
 880 <p>So in conclusion, what I believe is that, if it weren't for the world
 881 being so bad, it should be very clear to the political decision makers
 882 that the only way to go nowadays is free software for various reasons,
 883 but I have learnt that the only way that seems to work is bottom up.</p>
 884
 885 <!--
 886
 887 >  * Who should be interviewed with this questions in the future?
 888
 889 That's probably the hardest question of them all, as I do not know the
 890 community. However, I would be willing to do the following:
 891
 892  <li>Run an interview with a German headteacher who is very open to
 893    free software, and also prefers it, but cannot really use it because
 894    of the decision makers above;
 895  <li>Run interviews with some kids, both with and without previous
 896    knowledge about free software
 897
 898 If that is wanted, just let me know ;).

 914       <div class="date">10th December 2013</div>
 915       <div class="body"><p>Helga 18. og 19. januar 2014 arrangeres
 916 <a href="http://makerfaireoslo.no/no/program/dugnadsnett">Oslo Maker
 917 Faire</a>, og <a href="http://www.dugnadsnett.no/">Dugnadsnett for
 918 alle</a> har fått plass!  Planen er å ha et bord med en plakat der vi
 919 forteller om hva Dugnadsnett for alle er for noe, og et lite verksted
 920 der vi hjelper folk som er interessert i å få opp sin egen mesh-node.
 921 Jeg gleder meg til å se hvordan prosjektet blir mottatt der.</p>
 922
 923 <p>Målet med dugnadsnett for alle i Oslo er å få på plass et datanett
 924 for kommunikasjon ved hjelp av radio-repeaterstasjoner (kalt
 925 mesh-noder) som gjør at en kan direkte kommunisere med slekt, venner
 926 og bekjente i Oslo via andre som deltar i dugnadsnettet, samt gjøre
 927 det mulig komme ut på internett via dugnadsnettet.  Første delmål er å
 928 kunne sende SMS-meldinger vha. IP-telefoni løsningen
 929 <a href="http://www.servalproject.org/">Serval project</a> mellom
 930 deltagerne i Dugnadsnett for alle i Oslo.  Formålet er å ta tilbake
 931 kontrollen over egen nett-infrastruktur og gjøre det dyrere å bedrive
 932 massiv innsamling av informasjon om borgernes bruk av datanett.</p>
 933
 934 <p>Høres dette interessant ut?  Bli med på prosjektet, fortell oss
 935 hvor du kunne tenke deg å sette opp en radio-repeater (slik at folk i
 936 nærheten kan finne hverandre ved hjelp av
 937 <a href="http://flynor.net/mesh/mesh.php">kartet over planlagte og
 938 eksisterende radio-repeatere</A>), bli med på epostlisten
 939 <a href="http://lists.nuug.no/mailman/listinfo/dugnadsnett">dugnadsnett
 940 (at) nuug.no</a> og stikk innom
 941 <a href="irc://irc.freenode.net/#dugnadsnett.no">IRC-kanalen
 942 #dugnadsnett.no</a>.  Så langt er det planlagt over 40
 943 radio-repeatere, med VPN-forbindelser via Internet for å la de delene
 944 av nettet som ikke når hverandre via radio kunne snakke med hverandre
 945 likevel.</p>
