All it took was a quick -visit to the BIOS during boot it disable it.</p> - -<p>But there is a fatal problem with the laptop. The 180 GB SSD disk -lock up during load. And this happen when installing Debian Wheezy -with encrypted disk, while the disk is being filled with random data. -I also tested to install Ubuntu Raring, and it happen there too if I -reenable the code to fill the disk with random data (it is disabled by -default in Ubuntu). And the bug with is already known. It was -reported to Debian as <a href="http://bugs.debian.org/691427">BTS -report #691427 2012-10-25</a> (journal commit I/O error on brand-new -Thinkpad T430s ext4 on lvm on SSD).

The design for handling this +in <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>, is +to update the automount rules in LDAP and let the automount daemon on +the clients take care of the rest. I was reminded about the need to +document this better when one of the customers of +<a href="http://www.slxdrift.no/">Skolelinux Drift AS</a>, where I am +on the board of directors, asked about how to do this. The steps to +get this working are the following:</p> + +<p><ol> + +<li>Add new storage server in DNS. I use nas-server.intern as the +example host here.</li> + +<li>Add automoun LDAP information about this server in LDAP, to allow +all clients to automatically mount it on reqeust.</li> + +<li>Add the relevant entries in tjener.intern:/etc/fstab, because +tjener.intern do not use automount to avoid mounting loops.</li> + +</ol></p> + +<p>DNS entries are added in GOsa², and not described here. Follow the +<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted">instructions +in the manual</a> (Machine Management with GOsa² in section Getting +started).</p> + +<p>Ensure that the NFS export points on the server are exported to the +relevant subnets or machines:</p> + +<p><blockquote><pre> +root@tjener:~# showmount -e nas-server +Export list for nas-server: +/storage 10.0.0.0/8 +root@tjener:~# +</pre></blockquote></p> + +<p>Here everything on the backbone network is granted access to the +/storage export. With NFSv3 it is slightly better to limit it to +netgroup membership or single IP addresses to have some limits on the +NFS access.</p> + +<p>The next step is to update LDAP. This can not be done using GOsa², +because it lack a module for automount. Instead, use ldapvi and add +the required LDAP objects using an editor.</p> + +<p><blockquote><pre> +ldapvi --ldap-conf -ZD '(cn=admin)' -b ou=automount,dc=skole,dc=skolelinux,dc=no +</pre></blockquote></p> + +<p>When the editor show up, add the following LDAP objects at the +bottom of the document. The "/&" part in the last LDAP object is a +wild card matching everything the nas-server exports, removing the +need to list individual mount points in LDAP.</p> + +<p><blockquote><pre> +add cn=nas-server,ou=auto.skole,ou=automount,dc=skole,dc=skolelinux,dc=no +objectClass: automount +cn: nas-server +automountInformation: -fstype=autofs --timeout=60 ldap:ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no + +add ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no +objectClass: top +objectClass: automountMap +ou: auto.nas-server + +add cn=/,ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no +objectClass: automount +cn: / +automountInformation: -fstype=nfs,tcp,rsize=32768,wsize=32768,rw,intr,hard,nodev,nosuid,noatime nas-server.intern:/& +</pre></blockquote></p> + +<p>The last step to remember is to mount the relevant mount points in +tjener.intern by adding them to /etc/fstab, creating the mount +directories using mkdir and running "mount -a" to mount them.</p> + +<p>When this is done, your users should be able to access the files on +the storage server directly by just visiting the +/tjener/nas-server/storage/ directory using any application on any +workstation, LTSP client or LTSP server.</p> - Fourth alpha release of Debian Edu/Skolelinux based on Debian Wheezy - http://people.skolelinux.org/pere/blog/Fourth_alpha_release_of_Debian_Edu_Skolelinux_based_on_Debian_Wheezy.html - http://people.skolelinux.org/pere/blog/Fourth_alpha_release_of_Debian_Edu_Skolelinux_based_on_Debian_Wheezy.html - Wed, 3 Jul 2013 14:00:00 +0200 - <p>The fourth wheezy based alpha release of Debian Edu was wrapped up -today.

Jeg lurer på +om denne kjernen kan være nyttig i et par av mine prosjekter, og for ett +av dem er det mest aktuelt å lagre epost. Jeg klarte ikke finne noen +anbefaling om hvordan RFC 822-formattert epost (aka Internett-epost) +burde lagres i NOARK5, selv om jeg vet at noen arkiver tar +PDF-utskrift av eposten med sitt epostprogram og så arkiverer PDF-en +(eller enda værre, tar papirutskrift og lagrer bildet av eposten som +PDF i arkivet).</p> + +<p>Det er ikke så mange formater som er akseptert av riksarkivet til +langtidsoppbevaring av offentlige arkiver, og PDF og XML er de mest +aktuelle i så måte. Det slo meg at det måtte da finnes en eller annen +egnet XML-representasjon og at det kanskje var enighet om hvilken som +burde brukes, så jeg tok mot til meg og spurte +<a href="http://samdok.com/">SAMDOK</a>, en gruppe tilknyttet +arkivverket som ser ut til å jobbe med NOARK-samhandling, om de hadde +noen anbefalinger: + +<p><blockquote> +<p>Hei.</p> + +<p>Usikker på om dette er riktig forum å ta opp mitt spørsmål, men jeg +lurer på om det er definert en anbefaling om hvordan RFC +822-formatterte epost (aka vanlig Internet-epost) bør lages håndteres +i NOARK5, slik at en bevarer all informasjon i eposten +(f.eks. Received-linjer). Finnes det en anbefalt XML-mapping ala den +som beskrives på +&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 +mål er at det skal være mulig å lagre eposten i en NOARK5-kjerne og +kunne få ut en identisk formattert kopi av opprinnelig epost ved +behov.</p> +</blockquote></p> + +<p>Postmottaker hos SAMDOK mente spørsmålet heller burde stilles +direkte til riksarkivet, og jeg fikk i dag svar derfra formulert av +seniorrådgiver Geir Ivar Tungesvik:</p> + +<p><blockquote> +<p>Riksarkivet har ingen anbefalinger når det gjelder konvertering fra +e-post til XML. Det står arkivskaper fritt å eventuelt definere/bruke +eget format. Inklusive da - som det spørres om - et format der det er +mulig å re-etablere e-post format ut fra XML-en. XML (e-post) +dokumenter må være referert i arkivstrukturen, og det må vedlegges et +gyldig XML skjema (.xsd) for XML-filene. Arkivskaper står altså fritt +til å gjøre hva de vil, bare det dokumenteres og det kan dannes et +utrekk ved avlevering til depot.</p> + +<p>De obligatoriske kravene i Noark 5 standarden må altså oppfylles - +etter dialog med Riksarkivet i forbindelse med godkjenning. For +offentlige arkiv er det særlig viktig med filene loependeJournal.xml +og offentligJournal.xml. Private arkiv som vil forholde seg til Noark +5 standarden er selvsagt frie til å bruke det som er relevant for dem +av obligatoriske krav.</p> +</blockquote></p> + +<p>Det ser dermed ut for meg som om det er et lite behov for å +standardisere XML-lagring av RFC-822-formatterte meldinger. Noen som +vet om god spesifikasjon i så måte?

It test that the LDAP service is -operating, Kerberos is responding, DNS is replying, file systems are -online resizable, etc, etc. And it check that the PXE service is -configured, which is the topic of this post.</p> - -<p>The last week I've fixed the DVD and USB stick ISOs for our Debian -Edu Wheezy release. These ISOs are supposed to be able to install a -complete system without any Internet connection, but for that to -happen all the needed packages need to be on them. Thanks to our test -suite, I discovered that we had forgotten to adjust our PXE setup to -cope with the new names and paths used by the netboot d-i packages. -When Internet connectivity was available, the installer fall back to -using wget to fetch d-i boot images, but when offline it require -working packages to get it working. And ad the packages changed name -from debian-installer-6.0-netboot-$arch to -debian-installer-7.0-netboot-$arch, we no longer pulled in the -packages during installation. Without our test suite, I suspect we -would never have discovered this before release. Now it is fixed -right after we got the ISOs operational.</p> - -<p>Another by-product of the test suite is that we can ask system -administrators with problems getting Debian Edu to work, to run the -test suite using <tt>/usr/sbin/debian-edu-test-install</tt> and see if -any errors are detected.

I called the project +ng-utils, and it has served me well. I placed the project under the +<a href="http://www.hungry.com/">Hungry Programmer</a> umbrella, and it was maintained in our CVS +repository. But many years ago, the CVS repository was dropped (lost, +not migrated to new hardware, not sure), and the project have lacked a +proper home since then.</p> + +<p>Last summer, I had a look at the package and made a new release +fixing a irritating crash bug, but was unable to store the changes in +a proper source control system. I applied for a project on +<a href="https://alioth.debian.org/">Alioth</a>, but did not have time +to follow up on it. Until today. :)</p> + +<p>After many hours of cleaning and migration, the ng-utils project +now have a new home, and a git repository with the highlight of the +history of the project. I published all release tarballs and imported +them into the git repository.

Immediately after installation a school server running all -services needed for a school network is set up just waiting for users -and machines being added via GOsa², a comfortable Web-UI. A netbooting -environment is prepared using PXE, so after initial installation of -the main server from CD, DVD or USB stick all other machines can be -installed via the network. The provided school server provides LDAP -database and Kerberos authentication service, centralized home -directories, DHCP server, web proxy and many other services. The -desktop contains -<a href="http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html">more -than 60 educational software packages</a> and more are available from -the Debian archive, and schools can choose between KDE, Gnome, LXDE -and Xfce desktop environment.</p> - -<p>This is the third test release based on Debian Wheezy.

This follow up on the +<a href="https://teythoon.cryptobitch.de//categories/gsoc.html">great +Google Summer of Code work</a> done last summer by Justus Winter to +get Debian on Hurd working more like Debian on Linux. To get started, +I downloaded a prebuilt hard disk image from +<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>, +and started it using virt-manager.</p> + +<p>The first think I had to do after logging in (root without any +password) was to get the network operational. I followed +<a href="https://www.debian.org/ports/hurd/hurd-install">the +instructions on the Debian GNU/Hurd ports page</a> and ran these +commands as root to get the machine to accept a IP address from the +kvm internal DHCP server:</p> + +<p><blockquote><pre> +settrans -fgap /dev/netdde /hurd/netdde +kill $(ps -ef|awk '/[p]finet/ { print $2}') +kill $(ps -ef|awk '/[d]evnode/ { print $2}') +dhclient /dev/eth0 +</pre></blockquote></p> + +<p>After this, the machine had internet connectivity, and I could +upgrade it and install the sysvinit packages from experimental and +enable it as the default boot system in Hurd.</p> + +<p>But before I did that, I set a password on the root user, as ssh is +running on the machine it for ssh login to work a password need to be +set. Also, note that a bug somewhere in openssh on Hurd block +compression from working. Remember to turn that off on the client +side.</p> + +<p>Run these commands as root to upgrade and test the new sysvinit +stuff:</p> + +<p><blockquote><pre> +cat > /etc/apt/sources.list.d/experimental.list &lt;&lt;EOF +deb http://http.debian.net/debian/ experimental main +EOF +apt-get update +apt-get dist-upgrade +apt-get install -t experimental initscripts sysv-rc sysvinit \ + sysvinit-core sysvinit-utils +update-alternatives --config runsystem +</pre></blockquote></p> + +<p>To reboot after switching boot system, you have to use +<tt>reboot-hurd</tt> instead of just <tt>reboot</tt>, as there is not +yet a sysvinit process able to receive the signals from the normal +'reboot' command. After switching to sysvinit as the boot system, +upgrading every package and rebooting, the network come up with DHCP +after boot as it should, and the settrans/pkill hack mentioned at the +start is no longer needed. But for some strange reason, there are no +longer any login prompt in the virtual console, so I logged in using +ssh instead. + +<p>Note that there are some race conditions in Hurd making the boot +fail some times. No idea what the cause is, but hope the Hurd porters +figure it out. At least Justus said on IRC (#debian-hurd on +irc.debian.org) that they are aware of the problem. A way to reduce +the impact is to upgrade to the Hurd packages built by Justus by +adding this repository to the machine:</p> + +<p><blockquote><pre> +cat > /etc/apt/sources.list.d/hurd-ci.list &lt;&lt;EOF +deb http://darnassus.sceen.net/~teythoon/hurd-ci/ sid main +EOF +</pre></blockquote></p> + +<p>At the moment the prebuilt virtual machine get some packages from +http://ftp.debian-ports.org/debian, because some of the packages in +unstable do not yet include the required patches that are lingering in +BTS. This is the completely list of "unofficial" packages installed:</p> + +<p><blockquote><pre> +# aptitude search '?narrow(?version(CURRENT),?origin(Debian Ports))' +i emacs - GNU Emacs editor (metapackage) +i gdb - GNU Debugger +i hurd-recommended - Miscellaneous translators +i isc-dhcp-client - ISC DHCP client +i isc-dhcp-common - common files used by all the isc-dhcp* packages +i libc-bin - Embedded GNU C Library: Binaries +i libc-dev-bin - Embedded GNU C Library: Development binaries +i libc0.3 - Embedded GNU C Library: Shared libraries +i A libc0.3-dbg - Embedded GNU C Library: detached debugging symbols +i libc0.3-dev - Embedded GNU C Library: Development Libraries and Hea +i multiarch-support - Transitional package to ensure multiarch compatibilit +i A x11-common - X Window System (X.Org) infrastructure +i xorg - X.Org X Window System +i A xserver-xorg - X.Org X server +i A xserver-xorg-input-all - X.Org X server -- input driver metapackage +# +</pre></blockquote></p> + +<p>All in all, testing hurd has been an interesting experience. :) +X.org did not work out of the box and I never took the time to follow +the porters instructions to fix it. This time I was interested in the +command line stuff.<p> + + + + + A fist full of non-anonymous Bitcoins + http://people.skolelinux.org/pere/blog/A_fist_full_of_non_anonymous_Bitcoins.html + http://people.skolelinux.org/pere/blog/A_fist_full_of_non_anonymous_Bitcoins.html + Wed, 29 Jan 2014 14:10:00 +0100 + <p>Bitcoin is a incredible use of peer to peer communication and +encryption, allowing direct and immediate money transfer without any +central control. It is sometimes claimed to be ideal for illegal +activity, which I believe is quite a long way from the truth. At least +I would not conduct illegal money transfers using a system where the +details of every transaction are kept forever. This point is +investigated in +<a href="https://www.usenix.org/publications/login">USENIX ;login:</a> +from December 2013, in the article +"<a href="https://www.usenix.org/system/files/login/articles/03_meiklejohn-online.pdf">A +Fistful of Bitcoins - Characterizing Payments Among Men with No +Names</a>" by Sarah Meiklejohn, Marjori Pomarole,Grant Jordan, Kirill +Levchenko, Damon McCoy, Geoffrey M. Voelker, and Stefan Savage. They +analyse the transaction log in the Bitcoin system, using it to find +addresses belong to individuals and organisations and follow the flow +of money from both Bitcoin theft and trades on Silk Road to where the +money end up. This is how they wrap up their article:</p> + +<p><blockquote> +<p>"To demonstrate the usefulness of this type of analysis, we turned +our attention to criminal activity. In the Bitcoin economy, criminal +activity can appear in a number of forms, such as dealing drugs on +Silk Road or simply stealing someone else’s bitcoins. We followed the +flow of bitcoins out of Silk Road (in particular, from one notorious +address) and from a number of highly publicized thefts to see whether +we could track the bitcoins to known services. Although some of the +thieves attempted to use sophisticated mixing techniques (or possibly +mix services) to obscure the flow of bitcoins, for the most part +tracking the bitcoins was quite straightforward, and we ultimately saw +large quantities of bitcoins flow to a variety of exchanges directly +from the point of theft (or the withdrawal from Silk Road).</p> + +<p>As acknowledged above, following stolen bitcoins to the point at +which they are deposited into an exchange does not in itself identify +the thief; however, it does enable further de-anonymization in the +case in which certain agencies can determine (through, for example, +subpoena power) the real-world owner of the account into which the +stolen bitcoins were deposited. Because such exchanges seem to serve +as chokepoints into and out of the Bitcoin economy (i.e., there are +few alternative ways to cash out), we conclude that using Bitcoin for +money laundering or other illicit purposes does not (at least at +present) seem to be particularly attractive."</p> +</blockquote><p> + +<p>These researches are not the first to analyse the Bitcoin +transaction log. The 2011 paper +"<a href="http://arxiv.org/abs/1107.4524">An Analysis of Anonymity in +the Bitcoin System</A>" by Fergal Reid and Martin Harrigan is +summarized like this:</p> + +<p><blockquote> +"Anonymity in Bitcoin, a peer-to-peer electronic currency system, is a +complicated issue. Within the system, users are identified by +public-keys only. An attacker wishing to de-anonymize its users will +attempt to construct the one-to-many mapping between users and +public-keys and associate information external to the system with the +users. Bitcoin tries to prevent this attack by storing the mapping of +a user to his or her public-keys on that user's node only and by +allowing each user to generate as many public-keys as required. In +this chapter we consider the topological structure of two networks +derived from Bitcoin's public transaction history. We show that the +two networks have a non-trivial topological structure, provide +complementary views of the Bitcoin system and have implications for +anonymity. We combine these structures with external information and +techniques such as context discovery and flow analysis to investigate +an alleged theft of Bitcoins, which, at the time of the theft, had a +market value of approximately half a million U.S. dollars." +</blockquote></p> + +<p>I hope these references can help kill the urban myth that Bitcoin +is anonymous. It isn't really a good fit for illegal activites. Use +cash if you need to stay anonymous, at least until regular DNA +sampling of notes and coins become the norm. :)</p> + +<p>As usual, if you use Bitcoin and want to show your support of my +activities, please send Bitcoin donations to my address +<b><a href="bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&label=PetterReinholdtsenBlog">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a></b>.</p> + + + + + New chrpath release 0.16 + http://people.skolelinux.org/pere/blog/New_chrpath_release_0_16.html + http://people.skolelinux.org/pere/blog/New_chrpath_release_0_16.html + Tue, 14 Jan 2014 11:00:00 +0100 + <p><a href="http://www.coverity.com/">Coverity</a> is a nice tool to +find problems in C, C++ and Java code using static source code +analysis.

Due to my (only partially +voluntary) huge engagement in the open source world, these things are +a bit vacant right now however.</p> + +<p>I also have been working as a project teacher at a Gymasnium +(public school) for various years now. I took up that work some time +around 2005 when still attending that school myself and have continued +it until today. I also had been running the (kind of very advanced) +network of that school together with a team of very interested and +talented students in the age of 11 to 15 years, who took the chance to +learn a lot about open source and networking before I left the school +to help building another school's informational education concept from +scratch.</p> + +<p>That said, one might see me as a kind of "glue" between school kids +and the elderly of teachers as well as between the open source +ecosystem and the (even more complex) educational ecosystem.</p> + +<p>When I am not busy with open source or education, I like Geocaching +and cycling.</p> -<li>Update thin client and diskless workstation setup to work with -LTSP in Wheezy.</li> +<p><strong>How did you get in contact with the Skolelinux / Debian Edu +project?</strong></p> -<li>Diskless workstations now run out of the box -- no need to set -them up with GOsa².</li> +<p>I think that happened some time around 2009 when I first attended +<a href="http://www.froscon.org">FrOSCon</a> and visited the project +booth. I think I wasn't too interested back then because I used to +have an attitude of disliking software that does too much stuff on its +own. Maybe I was too inexperienced to realise the upsides of an +"out-of-the-box" solution ;).</p> + +<p>The first time I actively talked to Skolelinux people was at +<a href="http://www.openrheinruhr.de">OpenRheinRuhr</a> 2011 when the +BiscuIT project, a home-grewn software used by my school for various +really cool things from timetables and class contact lists to lunch +ordering, student ID card printing and project elections first got to +a stage where it could have been published. I asked the Skolelinux +guys running the booth if the project were interested in it and gave a +small demonstration, but there wasn't any real feedback and the guys +seemed rather uninterested.</p> + +<p>After I left the school where I developed the software, it got +mostly lost, but I am now reimplementing it for my new school. I have +reusability and compatibility in mind, and I hop there will be a new +basis for contributing it to the Skolelinux project ;)!</p> -<li>Update IMAP server setup. </li> +<p><strong>What do you see as the advantages of Skolelinux / Debian +Edu?</strong></p> -<li>Fix login into Skolelinux Backup Tool (Closed in -slbackup-php/0.4.4-1: #700257: slbackup-php: Fails to submit correctly -entered password). </li> +<p>The most important advantage seems to be that it "just +works". After overcoming some minor (but still very annoying) glitches +in the installer, I got a fully functional, working school network, +without the month-long hassle I experienced when setting all that up +from scratch in earlier years. And above that, it rocked - I didn't +have any real hardware at hand, because the school was just founded +and has no money whatsoever, so I installed a combined server (main +server, terminal services and workstation) in a VM on my personal +notebook, bridging the LTSP network interface to the ethernet port, +and then PXE-booted the Windows notebooks that were lying around from +it. I could use 8 clients without any performance issues, by using a +tiny little VM on a tiny little notebook. I think that's enough to say +that it rocks!</p> + +<p>Secondly, there are marketing reasons. Life's bad, and so no +politician will ever permit a setup described as "Debian, an universal +operating system, with some really cool educational tools" while they +will be jsut fine with "Skolelinux, a single-purpose solution for your +school network", even if both turn out to be the very same thing (yes, +this is unfair towards the Skolelinux project, and must not be taken +too seriously - you get the idea, anyway).</p> -</ul> +<p><strong>What do you see as the disadvantages of Skolelinux / Debian +Edu?</strong></p> -<p><strong>Known issues</strong></p> +<p>I have not been involved with Skolelinux long enough to really +answer this question in a fair way.

But +that won't work out as long as the acceptance of free alternatives +grows globally. What I mean is that if all the kids are almost forced +to use Windows, Facebook, Skype, you name it at home, they will not +see why they would want to use alternatives at school. I have seen +students take seat in front of a fully-functional, modern Debian +desktop that could do anything their Windows at home could do, and +they jsut refused to use it because "Linux sucks". It is something +that makes the council of our city spend around 600000 € to buy +software - not including hardware, mind you - for operating school +networks, and for installing a system that, as has been proved, does +not work. For those of you readers who are good at maths, have you +already found out how many lives could have been saved with that money +if we had instead used it to bring education to parts of the world +that need it? I have, and found it to be nothing less dramatic than +plain criminal.</p> + +<p>That said, the only feasible way appears to be the bottom up +method. We have to bring free software to kids and parents. I have +founded an association named +<a href="https://www.teckids.org">Teckids</a> here in Germany that does +just that. We organise several events for kids and adolescents in the +area of free and open source software, for example the +<a href="http://kids.froscon.org">FrogLabs</a>, which share staff with +Teckids and are the youth programme of +<a href="http://www.froscon.org">the Free and Open Source Software +Conference (FrOSCon)</a>. We do a lot more than most other conferences +- this year, we first offered the FrogLabs as a holiday camp for kids +aged 10 to 16. It was a huge success, with approx. 30 kids taking part +and learning with and about free software through a whole weekend. All +of us had a lot of fun, and the results were really exciting.</p> + +<p>Apart from that, we are preparing a campaign that is supposed to bring +the message of free alternatives to stuff kids use every day to them and +their parents, e.g. the use of Jabber / Jappix instead of Facebook and +Skype. To make that possible, we are planning to get together a team of +clever kids who understand very well what their peers need and can bring +it across to them. So we will have a peer-driven network of adolescents +who teach each other and collect feedback from the community of minors. +We then take that feedback and our own experience to work closely with +open source projects, such as Skolelinux or Jappix, at improving their +software in a way that makes it more and more attractive for the target +group. At least I hope that we will have good cooperation with +Skolelinux in the future ;)!</p> + +<p>So in conclusion, what I believe is that, if it weren't for the world +being so bad, it should be very clear to the political decision makers +that the only way to go nowadays is free software for various reasons, +but I have learnt that the only way that seems to work is bottom up.</p> + +<!-- + +> * Who should be interviewed with this questions in the future? + +That's probably the hardest question of them all, as I do not know the +community. However, I would be willing to do the following: + + <li>Run an interview with a German headteacher who is very open to + free software, and also prefers it, but cannot really use it because + of the decision makers above; + <li>Run interviews with some kids, both with and without previous + knowledge about free software + +If that is wanted, just let me know ;). + +--> + + + + + Dugnadsnett for alle stiller på Oslo Maker Faire i januar 2014 + http://people.skolelinux.org/pere/blog/Dugnadsnett_for_alle_stiller_p__Oslo_Maker_Faire_i_januar_2014.html + http://people.skolelinux.org/pere/blog/Dugnadsnett_for_alle_stiller_p__Oslo_Maker_Faire_i_januar_2014.html + Tue, 10 Dec 2013 19:20:00 +0100 + <p>Helga 18. og 19. januar 2014 arrangeres +<a href="http://makerfaireoslo.no/no/program/dugnadsnett">Oslo Maker +Faire</a>, og <a href="http://www.dugnadsnett.no/">Dugnadsnett for +alle</a> har fått plass! Planen er å ha et bord med en plakat der vi +forteller om hva Dugnadsnett for alle er for noe, og et lite verksted +der vi hjelper folk som er interessert i å få opp sin egen mesh-node. +Jeg gleder meg til å se hvordan prosjektet blir mottatt der.</p> + +<p>Målet med dugnadsnett for alle i Oslo er å få på plass et datanett +for kommunikasjon ved hjelp av radio-repeaterstasjoner (kalt +mesh-noder) som gjør at en kan direkte kommunisere med slekt, venner +og bekjente i Oslo via andre som deltar i dugnadsnettet, samt gjøre +det mulig komme ut på internett via dugnadsnettet. Første delmål er å +kunne sende SMS-meldinger vha. IP-telefoni løsningen +<a href="http://www.servalproject.org/">Serval project</a> mellom +deltagerne i Dugnadsnett for alle i Oslo. Formålet er å ta tilbake +kontrollen over egen nett-infrastruktur og gjøre det dyrere å bedrive +massiv innsamling av informasjon om borgernes bruk av datanett.</p> + +<p>Høres dette interessant ut? Bli med på prosjektet, fortell oss +hvor du kunne tenke deg å sette opp en radio-repeater (slik at folk i +nærheten kan finne hverandre ved hjelp av +<a href="http://flynor.net/mesh/mesh.php">kartet over planlagte og +eksisterende radio-repeatere</A>), bli med på epostlisten +<a href="http://lists.nuug.no/mailman/listinfo/dugnadsnett">dugnadsnett +(at) nuug.no</a> og stikk innom +<a href="irc://irc.freenode.net/#dugnadsnett.no">IRC-kanalen +#dugnadsnett.no</a>. Så langt er det planlagt over 40 +radio-repeatere, med VPN-forbindelser via Internet for å la de delene +av nettet som ikke når hverandre via radio kunne snakke med hverandre +likevel.</p>
