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

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

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

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

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

 530 </pre></blockquote></p>
 531
 532 <p>All in all, testing hurd has been an interesting experience. :)
 533 X.org did not work out of the box and I never took the time to follow
 534 the porters instructions to fix it.  This time I was interested in the
 535 command line stuff.<p>

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

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

 697 project</a> consist of both newcomers and old timers, and this time I
 698 was able to get an interview with a newcomer in the project who showed
 699 up on the IRC channel a few weeks ago to let us know about his
 700 successful installation of Debian Edu Wheezy in his School.  Say hello
 701 to <a href="https://www.ohloh.net/accounts/Natureshadow">Dominik
 702 George</a>.</p>
 703
 704 <!-- http://www.dominik-george.de/images/foto.jpg -->
 705
 706 <p><strong>Who are you, and how do you spend your days?</strong></p>
 707
 708 <p>I am a 23 year-old student from Germany who has spent half of his
 709 life with open source. In "real life", I am, as already mentioned, a
 710 student in the fields of Computer Science, Electrical Engineering,
 711 Information Technologies and Anglistics. Due to my (only partially
 712 voluntary) huge engagement in the open source world, these things are
 713 a bit vacant right now however.</p>
 714
 715 <p>I also have been working as a project teacher at a Gymasnium
 716 (public school) for various years now. I took up that work some time
 717 around 2005 when still attending that school myself and have continued
 718 it until today. I also had been running the (kind of very advanced)
 719 network of that school together with a team of very interested and
 720 talented students in the age of 11 to 15 years, who took the chance to
 721 learn a lot about open source and networking before I left the school
 722 to help building another school's informational education concept from
 723 scratch.</p>
 724
 725 <p>That said, one might see me as a kind of "glue" between school kids
 726 and the elderly of teachers as well as between the open source
 727 ecosystem and the (even more complex) educational ecosystem.</p>
 728
 729 <p>When I am not busy with open source or education, I like Geocaching
 730 and cycling.</p>
 731
 732 <p><strong>How did you get in contact with the Skolelinux / Debian Edu
 733 project?</strong></p>
 734
 735 <p>I think that happened some time around 2009 when I first attended
 736 <a href="http://www.froscon.org">FrOSCon</a> and visited the project
 737 booth. I think I wasn't too interested back then because I used to
 738 have an attitude of disliking software that does too much stuff on its
 739 own. Maybe I was too inexperienced to realise the upsides of an
 740 "out-of-the-box" solution ;).</p>
 741
 742 <p>The first time I actively talked to Skolelinux people was at
 743 <a href="http://www.openrheinruhr.de">OpenRheinRuhr</a> 2011 when the
 744 BiscuIT project, a home-grewn software used by my school for various
 745 really cool things from timetables and class contact lists to lunch
 746 ordering, student ID card printing and project elections first got to
 747 a stage where it could have been published. I asked the Skolelinux
 748 guys running the booth if the project were interested in it and gave a
 749 small demonstration, but there wasn't any real feedback and the guys
 750 seemed rather uninterested.</p>
 751
 752 <p>After I left the school where I developed the software, it got
 753 mostly lost, but I am now reimplementing it for my new school. I have
 754 reusability and compatibility in mind, and I hop there will be a new
 755 basis for contributing it to the Skolelinux project ;)!</p>
 756
 757 <p><strong>What do you see as the advantages of Skolelinux / Debian
 758 Edu?</strong></p>
 759
 760 <p>The most important advantage seems to be that it "just
 761 works". After overcoming some minor (but still very annoying) glitches
 762 in the installer, I got a fully functional, working school network,
 763 without the month-long hassle I experienced when setting all that up
 764 from scratch in earlier years. And above that, it rocked - I didn't
 765 have any real hardware at hand, because the school was just founded
 766 and has no money whatsoever, so I installed a combined server (main
 767 server, terminal services and workstation) in a VM on my personal
 768 notebook, bridging the LTSP network interface to the ethernet port,
 769 and then PXE-booted the Windows notebooks that were lying around from
 770 it. I could use 8 clients without any performance issues, by using a
 771 tiny little VM on a tiny little notebook. I think that's enough to say
 772 that it rocks!</p>
 773
 774 <p>Secondly, there are marketing reasons. Life's bad, and so no
 775 politician will ever permit a setup described as "Debian, an universal
 776 operating system, with some really cool educational tools" while they
 777 will be jsut fine with "Skolelinux, a single-purpose solution for your
 778 school network", even if both turn out to be the very same thing (yes,
 779 this is unfair towards the Skolelinux project, and must not be taken
 780 too seriously - you get the idea, anyway).</p>

 782 <p><strong>What do you see as the disadvantages of Skolelinux / Debian
 783 Edu?</strong></p>
 784
 785 <p>I have not been involved with Skolelinux long enough to really
 786 answer this question in a fair way. Thus, please allow me to put it in
 787 other words: "What do you expect from Skolelinux to keep liking it?" I
 788 can list a few points about that:</p>
 789
 790 <ul>
 791
 792  <li>always strive to get all things integrated into Debian upstream
 793  <li>be open to discussion about changes and the like, even with newcomers
 794  <li>be helpful at being helpful ;)
 795
 796 </ul>
 797
 798 <p>I'm really sorry I cannot say much more about that :(!</p>
 799
 800 <p><strong>Which free software do you use daily?</strong></p>
 801
 802 <p>First of all, all software I use is free and open. I have abandoned
 803 all non-free software (except for firmware on my darned phone) this
 804 year.</p>
 805
 806 <p>I run Debian GNU/Linux on all PC systems I use. On that, I mostly
 807 run text tools. I use
 808 <a href="https://www.mirbsd.org/mksh.htm">mksh</a> as shell,
 809 <a href="https://www.mirbsd.org/jupp.htm">jupp</a> as very advanced
 810 text editor (I even got the developer to help me write a script/macro
 811 based full-featured student management software with the two),
 812 <a href="http://mcabber.com/">mcabber</a> for XMPP and
 813 <a href="http://www.irssi.org/">irssi</a> for IRC. For that overly
 814 coloured world called the WWW, I use
 815 <a href="https://www.mozilla.org/en-US/firefox/new/">Iceweasel
 816 (Firefox)</a>. Oh, and <a href="http://www.mutt.org/">mutt</a> for
 817 e-mail.</p>
 818
 819 <p>However, while I am personally aware of the fact that text tools
 820 are more efficient and powerful than anything else, I also use (or at
 821 least operate) some tools that are suitable to bring open source to
 822 kids. One of these things is <a href="http://jappix.org/">Jappix</a>,
 823 which I already introduced to some kids even before they got aware of
 824 Facebook, making them see for themselves that they do not need
 825 Facebook now ;).</p>
 826
 827 <p><strong>Which strategy do you believe is the right one to use to
 828 get schools to use free software?</strong></p>
 829
 830 <p>Well, that's a two-sided thing. One side is what I believe, and one
 831 side is what I have experienced.</p>
 832
 833 <p>I believe that the right strategy is showing them the benefits. But
 834 that won't work out as long as the acceptance of free alternatives
 835 grows globally. What I mean is that if all the kids are almost forced
 836 to use Windows, Facebook, Skype, you name it at home, they will not
 837 see why they would want to use alternatives at school. I have seen
 838 students take seat in front of a fully-functional, modern Debian
 839 desktop that could do anything their Windows at home could do, and
 840 they jsut refused to use it because "Linux sucks". It is something
 841 that makes the council of our city spend around 600000 € to buy
 842 software - not including hardware, mind you - for operating school
 843 networks, and for installing a system that, as has been proved, does
 844 not work. For those of you readers who are good at maths, have you
 845 already found out how many lives could have been saved with that money
 846 if we had instead used it to bring education to parts of the world
 847 that need it? I have, and found it to be nothing less dramatic than
 848 plain criminal.</p>
 849
 850 <p>That said, the only feasible way appears to be the bottom up
 851 method. We have to bring free software to kids and parents. I have
 852 founded an association named
 853 <a href="https://www.teckids.org">Teckids</a> here in Germany that does
 854 just that. We organise several events for kids and adolescents in the
 855 area of free and open source software, for example the
 856 <a href="http://kids.froscon.org">FrogLabs</a>, which share staff with
 857 Teckids and are the youth programme of
 858 <a href="http://www.froscon.org">the Free and Open Source Software
 859 Conference (FrOSCon)</a>. We do a lot more than most other conferences
 860 - this year, we first offered the FrogLabs as a holiday camp for kids
 861 aged 10 to 16. It was a huge success, with approx. 30 kids taking part
 862 and learning with and about free software through a whole weekend. All
 863 of us had a lot of fun, and the results were really exciting.</p>
 864
 865 <p>Apart from that, we are preparing a campaign that is supposed to bring
 866 the message of free alternatives to stuff kids use every day to them and
 867 their parents, e.g. the use of Jabber / Jappix instead of Facebook and
 868 Skype. To make that possible, we are planning to get together a team of
 869 clever kids who understand very well what their peers need and can bring
 870 it across to them. So we will have a peer-driven network of adolescents
 871 who teach each other and collect feedback from the community of minors.
 872 We then take that feedback and our own experience to work closely with
 873 open source projects, such as Skolelinux or Jappix, at improving their
 874 software in a way that makes it more and more attractive for the target
 875 group. At least I hope that we will have good cooperation with
 876 Skolelinux in the future ;)!</p>
 877
 878 <p>So in conclusion, what I believe is that, if it weren't for the world
 879 being so bad, it should be very clear to the political decision makers
 880 that the only way to go nowadays is free software for various reasons,
 881 but I have learnt that the only way that seems to work is bottom up.</p>
 882
 883 <!--
 884
 885 >  * Who should be interviewed with this questions in the future?
 886
 887 That's probably the hardest question of them all, as I do not know the
 888 community. However, I would be willing to do the following:
 889
 890  <li>Run an interview with a German headteacher who is very open to
 891    free software, and also prefers it, but cannot really use it because
 892    of the decision makers above;
 893  <li>Run interviews with some kids, both with and without previous
 894    knowledge about free software
 895
 896 If that is wanted, just let me know ;).
 897

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