- <div class="date">22nd April 2013</div>
- <div class="body"><p><a href="http://www.bitcoin.org/">Bitcoin</a> er mye i mediene for
-tiden. Jeg følger med via Mylder for å finne
-<a href="http://mylder.no/?drill=bitcoin">artikler som omtaler
-temaet</a>, og takket være dette oppdaget jeg at stortingsrepresentant
-Ketil Solvik-Olsen fra FrP nylig har spurt finansminister Sigbjørn
-Johnsen om hans syn på Bitcoin, og
-<a href="http://www.stortinget.no/no/Saker-og-publikasjoner/Sporsmal/Skriftlige-sporsmal-og-svar/Skriftlig-sporsmal/?qid=57052">fått
-svar for noen dager siden</a>. Jeg bet meg spesielt merke til
-følgende formulering fra finansministeren:</p>
-
-<p><blockquote>
-«Det er også utfordringer ved at handel med Bitcoins er uregulert og
-at transaksjonene er anonyme.»
-</blockquote></p>
-
-<p>At Bitcoin er anonymt er en myte som spres av både journalister og
-andre, så det er ikke veldig overraskende at også finansministeren har
-gått på limpinnen. Det er dog litt rart, da jeg håper at
-finansdepartementet ikke baserer seg på rykter og myter når de
-besvarer Stortinget. Men du trenger ikke bare tro på meg som kilde
-til påstanden om at Bitcoin ikke er anonymt. Sondre Rønjom har
-<a href="http://blogg.nsm.stat.no/archives/3241">via Sikkerhetsbloggen
-hos Nasjonal Sikkerhetsmyndighet</a> uttalt følgende:</p>
-
-<p><blockquote>
-«At [bitcoin] i utgangspunktet
-<a href="http://arxiv.org/abs/1107.4524"><em>ikke</em> er anonymt</a>,
-kommer kanskje som en overraskelse på mange.»
-</blockquote></p>
-
-<p>Enhver bevegelse av Bitcoin er offentlig tilgjengelig for alle på
-Internet, og en må legge svært mye innsats inn hvis en skal hindre at
-nettverksanalyse av transaksjonsloggene kan brukes til å identifisere
-brukerne. F.eks. kan en enkelt se hva jeg har mottatt til min
-offentliggjorte mottaksadresse ved å besøke blockexplorer og slå opp
-adressen
-<a href="http://blockexplorer.com/address/15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a>.
-Det virker dermed på meg ganske klart at å påstå at
-Bitcoin-transaksjoner er anonyme strengt tatt er å føre Stortinget bak
-lyset.</p>
-
-<p>Finansministeren er ikke den eneste som har latt seg forlede av
-medieomtalen. I spørsmålet fra Hr. Solvik-Olseb skriver han at «For
-noen dager siden kom den første bitcoin-minibanken på Kypros», hvilket
-så vidt jeg har klart å finne ut ikke er riktig. Det er annonsert
-planer om en slik minibank (fra
-<a href="http://www.bitcoinatm.com/">BitcoinATM</a>), men jeg finner
-intet tegn til at en slik minibank er utplassert noe sted.</p>
-
-<p>Som vanlig, hvis du bruker Bitcoin og ønsker å vise din støtte til
-mine aktiviteter, så setter jeg pris på Bitcoin-donasjoner til min
-adresse

+ <div class="date">27th October 2013</div>
+ <div class="body"><p>The
+<a href="http://packages.qa.debian.org/v/vmdebootstrap.html">vmdebootstrap</a>
+program is a a very nice system to create virtual machine images. It
+create a image file, add a partition table, mount it and run
+debootstrap in the mounted directory to create a Debian system on a
+stick. Yesterday, I decided to try to teach it how to make images for
+<a href="https://wiki.debian.org/RaspberryPi">Raspberry Pi</a>, as part
+of a plan to simplify the build system for
+<a href="https://wiki.debian.org/FreedomBox">the FreedomBox
+project</a>. The FreedomBox project already uses vmdebootstrap for
+the virtualbox images, but its current build system made multistrap
+based system for Dreamplug images, and it is lacking support for
+Raspberry Pi.</p>
+
+<p>Armed with the knowledge on how to build "foreign" (aka non-native
+architecture) chroots for Raspberry Pi, I dived into the vmdebootstrap
+code and adjusted it to be able to build armel images on my amd64
+Debian laptop. I ended up giving vmdebootstrap five new options,
+allowing me to replicate the image creation process I use to make
+<a href="http://people.skolelinux.org/pere/blog/A_Raspberry_Pi_based_batman_adv_Mesh_network_node.html">Debian
+Jessie based mesh node images for the Raspberry Pi</a>. First, the
+<tt>--foreign /path/to/binfm_handler</tt> option tell vmdebootstrap to
+call debootstrap with --foreign and to copy the handler into the
+generated chroot before running the second stage. This allow
+vmdebootstrap to create armel images on an amd64 host. Next I added
+two new options <tt>--bootsize size</tt> and <tt>--boottype
+fstype</tt> to teach it to create a separate /boot/ partition with the
+given file system type, allowing me to create an image with a vfat
+partition for the /boot/ stuff. I also added a <tt>--variant
+variant</tt> option to allow me to create smaller images without the
+Debian base system packages installed. Finally, I added an option
+<tt>--no-extlinux</tt> to tell vmdebootstrap to not install extlinux
+as a boot loader. It is not needed on the Raspberry Pi and probably
+most other non-x86 architectures. The changes were accepted by the
+upstream author of vmdebootstrap yesterday and today, and is now
+available from
+<a href="http://git.liw.fi/cgi-bin/cgit/cgit.cgi/vmdebootstrap/">the
+upstream project page</a>.</p>
+
+<p>To use it to build a Raspberry Pi image using Debian Jessie, first
+create a small script (the customize script) to add the non-free
+binary blob needed to boot the Raspberry Pi and the APT source
+list:</p>
+
+<p><pre>
+#!/bin/sh
+set -e # Exit on first error
+rootdir="$1"
+cd "$rootdir"
+cat <<EOF > etc/apt/sources.list
+deb http://http.debian.net/debian/ jessie main contrib non-free
+EOF
+# Install non-free binary blob needed to boot Raspberry Pi. This
+# install a kernel somewhere too.
+wget https://raw.github.com/Hexxeh/rpi-update/master/rpi-update \
+ -O $rootdir/usr/bin/rpi-update
+chmod a+x $rootdir/usr/bin/rpi-update
+mkdir -p $rootdir/lib/modules
+touch $rootdir/boot/start.elf
+chroot $rootdir rpi-update
+</pre></p>
+
+<p>Next, fetch the latest vmdebootstrap script and call it like this
+to build the image:</p>
+
+<pre>
+sudo ./vmdebootstrap \
+ --variant minbase \
+ --arch armel \
+ --distribution jessie \
+ --mirror http://http.debian.net/debian \
+ --image test.img \
+ --size 600M \
+ --bootsize 64M \
+ --boottype vfat \
+ --log-level debug \
+ --verbose \
+ --no-kernel \
+ --no-extlinux \
+ --root-password raspberry \
+ --hostname raspberrypi \
+ --foreign /usr/bin/qemu-arm-static \
+ --customize `pwd`/customize \
+ --package netbase \
+ --package git-core \
+ --package binutils \
+ --package ca-certificates \
+ --package wget \
+ --package kmod
+</pre></p>
+
+<p>The list of packages being installed are the ones needed by
+rpi-update to make the image bootable on the Raspberry Pi, with the
+exception of netbase, which is needed by debootstrap to find
+/etc/hosts with the minbase variant. I really wish there was a way to
+set up an Raspberry Pi using only packages in the Debian archive, but
+that is not possible as far as I know, because it boots from the GPU
+using a non-free binary blob.</p>
+
+<p>The build host need debootstrap, kpartx and qemu-user-static and
+probably a few others installed. I have not checked the complete
+build dependency list.</p>
+
+<p>The resulting image will not use the hardware floating point unit
+on the Raspberry PI, because the armel architecture in Debian is not
+optimized for that use. So the images created will be a bit slower
+than <a href="http://www.raspbian.org/">Raspbian</a> based images.</p>

+<a href="http://www.aftenposten.no/nyheter/uriks/Her-er-Edvard-Snowdens-mest-omtalte-avsloringer-7351734.html">den
+totale overvåkningen som foregår i den vestlige verden dokumenterer
+hvor sårbare vi er</a>. Men det slår meg at de som er mest sårbare
+for dette, myndighetspersoner på alle nivåer, neppe har innsett at de
+selv er de mest interessante personene å lage profiler på, for å kunne
+påvirke dem.</p>
+
+<p>For å ta et lite eksempel: Stortingets nettsted,
+<a href="http://www.stortinget.no/">www.stortinget.no</a> (og
+forsåvidt også
+<a href="http://data.stortinget.no/">data.stortinget.no</a>),
+inneholder informasjon om det som foregår på Stortinget, og jeg antar
+de største brukerne av informasjonen der er representanter og
+rådgivere på Stortinget. Intet overraskende med det. Det som derimot
+er mer skjult er at Stortingets nettsted bruker
+<a href="http://en.wikipedia.org/wiki/Google_Analytics">Google
+Analytics</a>, hvilket gjør at enhver som besøker nettsidene der også
+rapporterer om besøket via Internett-linjer som passerer Sverige,
+England og videre til USA. Det betyr at informasjon om ethvert besøk
+på stortingets nettsider kan snappes opp av svensk, britisk og USAs
+etterretningsvesen. De kan dermed holde et øye med hvilke
+Stortingssaker stortingsrepresentantene synes er interessante å sjekke
+ut, og hvilke sider rådgivere og andre på stortinget synes er
+interessant å besøke, når de gjør det og hvilke andre representanter
+som sjekker de samme sidene omtrent samtidig. Stortingets bruk av
+Google Analytics gjør det dermed enkelt for utenlands etteretning å
+spore representantenes aktivitet og interesse. Hvis noen av
+representantene bruker Google Mail eller noen andre tjenestene som
+krever innlogging, så vil det være enda enklere å finne ut nøyaktig
+hvilke personer som bruker hvilke nettlesere og dermed knytte
+informasjonen opp til enkeltpersoner på Stortinget.</p>
+
+<p>Og jo flere nettsteder som bruker Google Analytics, jo bedre
+oversikt over stortingsrepresentantenes lesevaner og interesse blir
+tilgjengelig for svensk, britisk og USAs etterretning. Hva de kan
+bruke den informasjonen til overlater jeg til leseren å undres
+over.</p>

- <div class="date"> 7th April 2013</div>
- <div class="body"><p>For en stund tilbake gikk nyheten om
-<a href="http://en.wikipedia.org/wiki/Sandy_Island,_New_Caledonia">Sandy
-Island</a>, en øy som var dukket opp på noen kart, men som ikke var
-synlig når en sjekket den på satellittbilder. Dagbladet meldte for
-eksempel at
-«<a href="http://www.dagbladet.no/2012/11/22/nyheter/google_maps/google/utenriks/internett/24496816/">denne
-øya finnes på kart, men ikke i virkeligheten</a>». Noe senere begynte
-jeg å lese
-<a href="http://www.gyldendal.no/Barn-og-ungdom/3-6-aar/Den-store-Ruffen-boken">historier
-om Ruffen</a> til mine barn. Dette er historier om sjøormen Ruffen
-skapt av Tor Åge Bringsværd, som starter med følgende beskrivelse:</p>
-
-<p><blockquote>
-«Langt ute i havet ligger en mystisk øy. Den er bare synlig hver
-tirsdag og fredag. Derfor står den ikke på noe kart. På denne øya
-ligger et slott, og i slottet bor en gammel, fin sjøormfamilie.»
-</blockquote></p>
-
-<p>Det virker åpenbart at Hr. Bringsværd tok feil når han trodde den
-ikke var på noe kart, og at noen tydeligvis har vært i nærheten en
-tirsdag eller en fredag og fått den med på et kart, mens
-satellittbildene er tatt på noen av de fem andre dagene i uka og
-dermed ikke ser øya. :)</p>
-
-<p>I følge
-<a href="http://www.dagbladet.no/2012/12/03/nyheter/sandy_island/forskning/utenriks/24662158/">en
-senere artikkel i Dagbladet</a> hevder Shaun Higgins, en forsker fra
-New Zealand, at et hvalfangstskip fra 1876 er opprinnelsen til at
-spøkelsesøya i det hele tatt havnet på kartet. Det fremgår ikke fra
-historien hvilken ukedag de var innom.</p>
-
-<p>Jeg har stor sans for Tor Åge Bringsværd. Og han viste nylig en

+ <div class="date">21st October 2013</div>
+ <div class="body"><p>The last few days I have been experimenting with
+<a href="http://www.open-mesh.org/projects/batman-adv/wiki">the
+batman-adv mesh technology</a>. I want to gain some experience to see
+if it will fit <a href="https://wiki.debian.org/FreedomBox">the
+Freedombox project</a>, and together with my neighbors try to build a
+mesh network around the park where I live. Batman-adv is a layer 2
+mesh system ("ethernet" in other words), where the mesh network appear
+as if all the mesh clients are connected to the same switch.</p>
+
+<p>My hardware of choice was the Linksys WRT54GL routers I had lying
+around, but I've been unable to get them working with batman-adv. So
+instead, I started playing with a
+<a href="http://www.raspberrypi.org/">Raspberry Pi</a>, and tried to
+get it working as a mesh node. My idea is to use it to create a mesh
+node which function as a switch port, where everything connected to
+the Raspberry Pi ethernet plug is connected (bridged) to the mesh
+network. This allow me to hook a wifi base station like the Linksys
+WRT54GL to the mesh by plugging it into a Raspberry Pi, and allow
+non-mesh clients to hook up to the mesh. This in turn is useful for
+Android phones using <a href="http://servalproject.org/">the Serval
+Project</a> voip client, allowing every one around the playground to
+phone and message each other for free. The reason is that Android
+phones do not see ad-hoc wifi networks (they are filtered away from
+the GUI view), and can not join the mesh without being rooted. But if
+they are connected using a normal wifi base station, they can talk to
+every client on the local network.</p>
+
+<p>To get this working, I've created a debian package
+<a href="https://github.com/petterreinholdtsen/meshfx-node">meshfx-node</a>
+and a script
+<a href="https://github.com/petterreinholdtsen/meshfx-node/blob/master/build-rpi-mesh-node">build-rpi-mesh-node</a>
+to create the Raspberry Pi boot image. I'm using Debian Jessie (and
+not Raspbian), to get more control over the packages available.
+Unfortunately a huge binary blob need to be inserted into the boot
+image to get it booting, but I'll ignore that for now. Also, as
+Debian lack support for the CPU features available in the Raspberry
+Pi, the system do not use the hardware floating point unit. I hope
+the routing performance isn't affected by the lack of hardware FPU
+support.</p>
+
+<p>To create an image, run the following with a sudo enabled user
+after inserting the target SD card into the build machine:</p>
+
+<p><pre>
+% wget -O build-rpi-mesh-node \
+ https://raw.github.com/petterreinholdtsen/meshfx-node/master/build-rpi-mesh-node
+% sudo bash -x ./build-rpi-mesh-node > build.log 2>&1
+% dd if=/root/rpi/rpi_basic_jessie_$(date +%Y%m%d).img of=/dev/mmcblk0 bs=1M
+%
+</pre></p>
+
+<p>Booting with the resulting SD card on a Raspberry PI with a USB
+wifi card inserted should give you a mesh node. At least it does for
+me with a the wifi card I am using. The default mesh settings are the
+ones used by the Oslo mesh project at Hackeriet, as I mentioned in
+<a href="http://people.skolelinux.org/pere/blog/Oslo_community_mesh_network___with_NUUG_and_Hackeriet_at_Hausmania.html">an
+earlier blog post about this mesh testing</a>.</p>
+
+<p>The mesh node was not horribly expensive either. I bought
+everything over the counter in shops nearby. If I had ordered online
+from the lowest bidder, the price should be significantly lower:</p>
+
+<p><table>
+
+<tr><th>Supplier</th><th>Model</th><th>NOK</th></tr>
+<tr><td>Teknikkmagasinet</td><td>Raspberry Pi model B</td><td>349.90</td></tr>
+<tr><td>Teknikkmagasinet</td><td>Raspberry Pi type B case</td><td>99.90</td></tr>
+<tr><td>Lefdal</td><td>Jensen Air:Link 25150</td><td>295.-</td></tr>
+<tr><td>Clas Ohlson</td><td>Kingston 16 GB SD card</td><td>199.-</td></tr>
+<tr><td>Total cost</td><td></td><td>943.80</td></tr>
+
+</table></p>
+
+<p>Now my mesh network at home consist of one laptop in the basement
+connected to my production network, one Raspberry Pi node on the 1th
+floor that can be seen by my neighbor across the park, and one
+play-node I use to develop the image building script. And some times
+I hook up my work horse laptop to the mesh to test it. I look forward
+to figuring out what kind of latency the batman-adv setup will give,
+and how much packet loss we will experience around the park. :)</p>

- <div class="date">27th March 2013</div>
- <div class="body"><p>For noen dager siden nevnte jeg at vi jobbet med å typesette en
-novelle med <a href="http://www.docbook.org/">DocBook</a>. I dag ble
-utgivelsen annonsert med følgende pressemelding fra Elektronisk
-Forpost Norge), som jeg gjengir i sin helhet:</p>
-
-<p><blockquote>
-
-<p><strong>EFN nyutgir Kodémus:</strong></p>
-
-<p><strong>Tor Åge Bringsværd-novelle om IT og overvåkning fra
-informasjonsteknologiens spedbarndom får nytt liv</strong></p>
-
-<p>Elektronisk Forpost Norge (EFN) er veldig glad for anledningen til
-å nyutgi Tor Åge Bringsværds novelle Kodémus i digitalt format for nye
-(og gamle) generasjoner. Novellen ble skrevet så tidlig som vinteren
-1968, og første gang trykt i novellesamlingen Probok på Gyldendal
-samme år.</p>
-
-<p>Informasjonsteknologi spiller en sentral rolle i Kodémus, og det er
-spennende å sammenligne beskrivelsen av IT fra 1968 med dagens IT i
-2013. Forskjellene er mange -- men det er jammen likhetene også. Ikke
-minst det at idag går jo nesten alle rundt med lillebrødre på seg!</p>
-
-<p>"Riktignok er det ikke påbudt å ha mobil," sier Thomas Gramstad,
-leder i EFN. "Men vi holder på å lage et samfunn der det blir så
-upraktisk eller tungvint å ikke ha det, at man i praksis ikke slipper
-unna. Og disse lillebrødrene sladrer hele tiden til staten (og til
-mange andre) om hvor vi er, hva vi gjør, hva vi bryr oss om, hva vi
-liker..."</p>
-
-<p>Det at Kodémus åpenbart er skrevet i en annen tid med en annen type
-IT og likevel virker så relevant idag, er i seg selv et hardtslående
-tankekors.</p>
-
-<p>Tross sitt IT-tema fantes ikke Kodémus i elektronisk form, og
-frivillige i EFN har skannet inn, OCR-tolket og korrekturlest
-novellen, og deretter kodet den i en rekke digitale formater.</p>
-
-<p>Forfatteren har gitt tillatelse til publisering av Kodémus under ny
-lisens, og novellen utgis av EFN med en Creative Commons (CC)
-fribrukslisens (nærmere bestemt lisensen CC-BY-NC-ND). For leserne
-eller brukerne innebærer dette at de får en klar og standardisert
-beskjed om hvilke rettigheter de har til å dele novellen videre med
-andre. For forfatteren innebærer dette økt synlighet og
-tilgjengelighet for verket, slik at det ikke blir glemt, da
-søkemotorer og nettlesere inneholder egne søkevalg for CC-lisenser, og
-mange brukere søker etter verk som de vet de kan dele og bruke på
-lovlig vis.</p>
-
-<p>EFN oppfordrer andre forfattere om å gi ut sine gamle tekster med
-en fribrukslisens, slik at tekstene ikke blir glemt og for å stimulere
-lovlig deling på nettet. EFN kan være behjelpelig med digitalisering
-og utlegging på nett, i den grad det finnes kapasitet blant EFNs
-medlemmer til dette. Vi mener at nyutgivelser av tekster under frie
-lisenser kan øke interessen rundt forfatterskapet, og vil gjerne bidra
-til dette.</p>
-
-<p>EFN utgir og deler med dette en novelle fra den digitale
-informasjonsteknologiens tidligste barndom. En novelle som fortsatt er
-full av vitalitet og aktualitet, og som derfor kan bidra til, og gi
-ettertanke i dagens debatter om IT, personvern, overvåkning og
-individets frihet og integritet.</p>
-
-<p>Du finner novellen her:
-<br><a href="http://efn.no/kodemus/">http://efn.no/kodemus/</a></p>
-
-<p>i flere forskjellige formater, for ulike plattformer. Per idag
-finnes novellen i disse formatene: EPUB, MOBI, XML, HTML, PDF og
-txt. Det kan bli flere formater senere, og evt. frivillige
-bidragsytere til dette er velkommen.</p>

-
-<p>EFN arbeider for dine borgerrettigheter i IT-samfunnet, for
-nettverks- og delingskultur, personvern og frihet fra overvåkning,
-åpne standarder, brukerstyrt programvare, retten til å kopiere, og
-styrking av det digitale sivilsamfunnet m.m.

-
-<p>Jeg håper flere forfattere ser verdien av å gjøre kulturen
-tilgjengelig for flere, og slår følge med Hr. Bringsværd i å gi ut
-sine verker med bruksvilkår med færre bruksbegrensinger enn
-opphavsretten legger opp til. Selv om jeg gjerne skulle sett at han
-hadde brukt en Creative Commons-lisens som tillot avledede verker og
-kommersiell bruk.</p>

- <div class="date">26th March 2013</div>
- <div class="body"><p>Would you like to help the environment and save money at the same
-time, without much sacrifice? A small step could be to change the
-font you use when printing.</p>
-
-<p>Three years ago,
-<a href="http://arstechnica.com/business/2010/04/last-year-printer-comparison-website/">Ars
-Technica</a> reported how the University of Wisconsin-Green Bay
-changed their default front from
-<a href="http://en.wikipedia.org/wiki/Arial">Arial</a> to
-<a href="http://en.wikipedia.org/wiki/Century_Gothic">Century
-Gothic</a> to save money. The Century Gothic font uses 30% less toner
-than Arial to print the same text. In other word, you could cut your
-toner costs by 30% (or actually, increase your toner supply life time
-by more than 30%), by simply changing the default font used in your
-prints.</p>
-
-<p>But it is not quite obvious how much one will save by switching.
-The University of Wisconsin-Green Bay said it used $100,000 per year
-on ink and toner cartridges, according to
-<a href="http://www.twincities.com/ci_14833097">a report from
-TwinCities.com</a>, and expected to save between $5,000 and $10,000
-per year by asking staff and students to use a different font. Not
-all PDFs and documents are created internally, and those from external
-sources will most likely still use a different font. Also, the
-Century Gothic font is slightly wider than Arial, and thus might use
-more sheets of paper to print the same text, so the total saving
-depend on the documents printed.</p>
-
-<p>But it is definitely something to consider, if you want to reduce
-the amount of trash, decrease the amount of toner used in the world,
-and save some money in the process.</p>
-
-<p>Update 2013-04-10: If you want to know how much ink/toner could be
-saved when switching between fonts, Inkfarm got a
-<a href="http://www.inkfarm.com/What-the-Font">service to calculate the
-difference between font pairs</a>. They also
-<a href="http://www.inkfarm.com/Recommended-Ink-Saving-Fonts---">recommend
-which fonts to use</a> to save ink. Check it out. :) While updating
-this blog post, I also came across a blog post from InkCloners,
-<a href="http://inkcloners.com/blog/ink-cartridges/change-fonts-to-save-ink-costs/">listing
-the fonts they recommend</a>, with Centory Gothic at the top.</p>

+ <div class="date">11th October 2013</div>
+ <div class="body"><p>Wireless mesh networks are self organising and self healing
+networks that can be used to connect computers across small and large
+areas, depending on the radio technology used. Normal wifi equipment
+can be used to create home made radio networks, and there are several
+successful examples like
+<a href="http://www.freifunk.net/">Freifunk</a> and
+<a href="http://www.awmn.net/">Athens Wireless Metropolitan Network</a>
+(see
+<a href="http://en.wikipedia.org/wiki/List_of_wireless_community_networks_by_region#Greece">wikipedia
+for a large list</a>) around the globe. To give you an idea how it
+work, check out the nice overview of the Kiel Freifunk community which
+can be seen from their
+<a href="http://freifunk.in-kiel.de/ffmap/nodes.html">dynamically
+updated node graph and map</a>, where one can see how the mesh nodes
+automatically handle routing and recover from nodes disappearing.
+There is also a small community mesh network group in Oslo, Norway,
+and that is the main topic of this blog post.</p>
+
+<p>I've wanted to check out mesh networks for a while now, and hoped
+to do it as part of my involvement with the <a
+href="http://www.nuug.no/">NUUG member organisation</a> community, and
+my recent involvement in
+<a href="https://wiki.debian.org/FreedomBox">the Freedombox project</a>
+finally lead me to give mesh networks some priority, as I suspect a
+Freedombox should use mesh networks to connect neighbours and family
+when possible, given that most communication between people are
+between those nearby (as shown for example by research on Facebook
+communication patterns). It also allow people to communicate without
+any central hub to tap into for those that want to listen in on the
+private communication of citizens, which have become more and more
+important over the years.</p>
+
+<p>So far I have only been able to find one group of people in Oslo
+working on community mesh networks, over at the hack space
+<a href="http://hackeriet.no/">Hackeriet</a> at Husmania. They seem to
+have started with some Freifunk based effort using OLSR, called
+<a href="http://oslo.freifunk.net/index.php?title=Main_Page">the Oslo
+Freifunk project</a>, but that effort is now dead and the people
+behind it have moved on to a batman-adv based system called
+<a href="http://meshfx.org/trac">meshfx</a>. Unfortunately the wiki
+site for the Oslo Freifunk project is no longer possible to update to
+reflect this fact, so the old project page can't be updated to point to
+the new project. A while back, the people at Hackeriet invited people
+from the Freifunk community to Oslo to talk about mesh networks. I
+came across this video where Hans Jørgen Lysglimt interview the
+speakers about this talk (from
+<a href="https://www.youtube.com/watch?v=N2Kd7CLkhSY">youtube</a>):</p>
+
+<p><iframe width="420" height="315" src="https://www.youtube.com/embed/N2Kd7CLkhSY" frameborder="0" allowfullscreen></iframe></p>
+
+<p>I mentioned OLSR and batman-adv, which are mesh routing protocols.
+There are heaps of different protocols, and I am still struggling to
+figure out which one would be "best" for some definitions of best, but
+given that the community mesh group in Oslo is so small, I believe it
+is best to hook up with the existing one instead of trying to create a
+completely different setup, and thus I have decided to focus on
+batman-adv for now. It sure help me to know that the very cool
+<a href="http://www.servalproject.org/">Serval project in Australia</a>
+is using batman-adv as their meshing technology when it create a self
+organizing and self healing telephony system for disaster areas and
+less industrialized communities. Check out this cool video presenting
+that project (from
+<a href="https://www.youtube.com/watch?v=30qNfzJCQOA">youtube</a>):</p>
+
+<p><iframe width="560" height="315" src="https://www.youtube.com/embed/30qNfzJCQOA" frameborder="0" allowfullscreen></iframe></p>
+
+<p>According to the wikipedia page on
+<a href="http://en.wikipedia.org/wiki/Wireless_mesh_network">Wireless
+mesh network</a> there are around 70 competing schemes for routing
+packets across mesh networks, and OLSR, B.A.T.M.A.N. and
+B.A.T.M.A.N. advanced are protocols used by several free software
+based community mesh networks.</p>
+
+<p>The batman-adv protocol is a bit special, as it provide layer 2
+(as in ethernet ) routing, allowing ipv4 and ipv6 to work on the same
+network. One way to think about it is that it provide a mesh based
+vlan you can bridge to or handle like any other vlan connected to your
+computer. The required drivers are already in the Linux kernel at
+least since Debian Wheezy, and it is fairly easy to set up. A
+<a href="http://www.open-mesh.org/projects/batman-adv/wiki/Quick-start-guide">good
+introduction</a> is available from the Open Mesh project. These are
+the key settings needed to join the Oslo meshfx network:</p>
+
+<p><table>
+<tr><th>Setting</th><th>Value</th></tr>
+<tr><td>Protocol / kernel module</td><td>batman-adv</td></tr>
+<tr><td>ESSID</td><td>meshfx@hackeriet</td></tr>
+<td>Channel / Frequency</td><td>11 / 2462</td></tr>
+<td>Cell ID</td><td>02:BA:00:00:00:01</td>
+</table></p>
+
+<p>The reason for setting ad-hoc wifi Cell ID is to work around bugs
+in firmware used in wifi card and wifi drivers. (See a nice post from
+VillageTelco about
+"<a href="http://tiebing.blogspot.no/2009/12/ad-hoc-cell-splitting-re-post-original.html">Information
+about cell-id splitting, stuck beacons, and failed IBSS merges!</a>
+for details.) When these settings are activated and you have some
+other mesh node nearby, your computer will be connected to the mesh
+network and can communicate with any mesh node that is connected to
+any of the nodes in your network of nodes. :)</p>
+
+<p>My initial plan was to reuse my old Linksys WRT54GL as a mesh node,
+but that seem to be very hard, as I have not been able to locate a
+firmware supporting batman-adv. If anyone know how to use that old
+wifi access point with batman-adv these days, please let me know.</p>
+
+<p>If you find this project interesting and want to join, please join
+us on IRC, either channel
+<a href="irc://irc.freenode.net/#oslohackerspace">#oslohackerspace</a>
+or <a href="irc://irc.freenode.net/#nuug">#nuug</a> on

+
+<p>While investigating mesh networks in Oslo, I came across an old
+research paper from the university of Stavanger and Telenor Research
+and Innovation called
+<a href="http://folk.uio.no/paalee/publications/netrel-egeland-iswcs-2008.pdf">The
+reliability of wireless backhaul mesh networks</a> and elsewhere
+learned that Telenor have been experimenting with mesh networks at
+Grünerløkka in Oslo. So mesh networks are also interesting for
+commercial companies, even though Telenor discovered that it was hard
+to figure out a good business plan for mesh networking and as far as I
+know have closed down the experiment. Perhaps Telenor or others would
+be interested in a cooperation?</p>
+
+<p><strong>Update 2013-10-12</strong>: I was just
+<a href="http://lists.alioth.debian.org/pipermail/freedombox-discuss/2013-October/005900.html">told
+by the Serval project developers</a> that they no longer use
+batman-adv (but are compatible with it), but their own crypto based
+mesh system.</p>

- <div class="date">24th March 2013</div>
- <div class="body"><p>A few days ago, during a discussion in
-<a href="http://www.efn.no/">EFN</a> about interesting books to read
-about copyright and the data retention directive, a suggestion to read
-the 1968 short story Kodémus by
-<a href="http://web2.gyldendal.no/toraage/">Tore Åge Bringsværd</a>
-came up. The text was only available in old paper books, and thus not
-easily available for current and future generations. Some of the
-people participating in the discussion contacted the author, and
-reported back 2013-03-19 that the author was OK with releasing the
-short story using a <a href="http://www.creativecommons.org/">Creative
-Commons</a> license. The text was quickly scanned and OCR-ed, and we
-were ready to start on the editing and typesetting.</p>
-
-<p>As I already had some experience formatting text in my project to
-provide a Norwegian version of the Free Culture book by Lawrence
-Lessig, I chipped in and set up a
-<a href="http://www.docbook.org/">DocBook</a> processing framework to
-generate PDF, HTML and EPUB version of the short story. The tools to
-transform DocBook to different formats are already in my Linux
-distribution of choice, <a href="http://www.debian.org/">Debian</a>, so
-all I had to do was to use the
-<a href="http://dblatex.sourceforge.net/">dblatex</a>,
-<a href="http://docbook.sourceforge.net/release/xsl/current/epub/README">dbtoepub</a>
-and <a href="https://fedorahosted.org/xmlto/">xmlto</a> tools to do the
-conversion. After a few days, we decided to replace dblatex with
-xsltproc/fop (aka
-<a href="http://wiki.docbook.org/DocBookXslStylesheets">docbook-xsl</a>),
-to get the copyright information to show up in the PDF and to get a
-nicer <variablelist> typesetting, but that is just a minor
-technical detail.</p>
-
-<p>There were a few challenges, of course. We want to typeset the
-short story to look like the original, and that require fairly good
-control over the layout. The original short story have three
-parts/scenes separated by a single horizontally centred star (*), and
-the paragraphs do not contain only flowing text, but dialogs and text
-that started on a new line in the middle of the paragraph.</p>
-
-<p>I initially solved the first challenge by using a paragraph with a
-single star in it, ie <para>*</para>, but it made sure a
-placeholder indicated where the scene shifted. This did not look too
-good without the centring. The next approach was to create a new
-preprocessor directive <?newscene?>, mapping to "<hr/>"
-for HTML and "<fo:block text-align="center"><fo:leader
-leader-pattern="rule" rule-thickness="0.5pt"/></fo:block>"
-for FO/PDF output (did not try to implement this in dblatex, as we had
-switched at this time). The HTML XSL file looked like this:</p>
-
-<p><blockquote><pre>
-<?xml version='1.0'?>
-<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'>
- <xsl:template match="processing-instruction('newscene')">
- <hr/>
- </xsl:template>
-</xsl:stylesheet>
-</pre></blockquote></p>
-
-<p>And the FO/PDF XSL file looked like this:</p>
-
-<p><blockquote><pre>
-<?xml version='1.0'?>
-<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'>
- <xsl:template match="processing-instruction('newscene')">
- <fo:block text-align="center">
- <fo:leader leader-pattern="rule" rule-thickness="0.5pt"/>
- </fo:block>
- </xsl:template>
-</xsl:stylesheet>
-</pre></blockquote></p>
-
-<p>Finally, I came across the <bridgehead> tag, which seem to be
-a good fit for the task at hand, and I replaced <?newscene?>
-with <bridgehead>*</bridgehead>. It isn't centred, but we
-can fix it with some XSL rule if the current visual layout isn't
-enough.</p>
-
-<p>I did not find a good DocBook compliant way to solve the
-linebreak/paragraph challenge, so I ended up creating a new processor
-directive <?linebreak?>, mapping to <br/> in HTML, and
-<fo:block/> in FO/PDF. I suspect there are better ways to do
-this, and welcome ideas and patches on github. The HTML XSL file now
-look like this:</p>
-
-<p><blockquote><pre>
-<?xml version='1.0'?>
-<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'>
- <xsl:template match="processing-instruction('linebreak)">
- <br/>
- </xsl:template>
-</xsl:stylesheet>
-</pre></blockquote></p>
-
-<p>And the FO/PDF XSL file looked like this:</p>
-
-<p><blockquote><pre>
-<?xml version='1.0'?>
-<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'
- xmlns:fo="http://www.w3.org/1999/XSL/Format">
- <xsl:template match="processing-instruction('linebreak)">
- <fo:block/>
- </xsl:template>
-</xsl:stylesheet>
-</pre></blockquote></p>
-
-<p>One unsolved challenge is our wish to expose different ISBN numbers
-per publication format, while keeping all of them in some conditional
-structure in the DocBook source. No idea how to do this, so we ended
-up listing all the ISBN numbers next to their format in the colophon
-page.</p>

-<p>If you want to check out the finished result, check out the
-<a href="https://github.com/sickel/kodemus">source repository at
-github</a>
-(<a href="https://github.com/EFN/kodemus">future/new/official
-repository</a>). We expect it to be ready and announced in a few
-days.</p>

+ <div class="date"> 8th October 2013</div>
+ <div class="body"><p>The other day I was pleased and surprised to discover that Marcelo
+Salvador had published a
+<a href="https://www.youtube.com/watch?v=w-GgpdqgLFc">video on
+Youtube</a> showing how to install the standalone Debian Edu /
+Skolelinux profile. This is the profile intended for use at home or
+on laptops that should not be integrated into the provided network
+services (no central home directory, no Kerberos / LDAP directory etc,
+in other word a single user machine). The result is 11 minutes long,
+and show some user applications (seem to be rather randomly picked).
+Missed a few of my favorites like celestia, planets and chromium
+showing the <a href="http://www.zygotebody.com/">Zygote Body 3D model
+of the human body</a>, but I guess he did not know about those or find
+other programs more interesting. :) And the video do not show the
+advantages I believe is one of the most valuable featuers in Debian
+Edu, its central school server making it possible to run hundreds of
+computers without hard drives by installing one central
+<a href="http://www.ltsp.org/">LTSP server</a>.</p>
+
+<p>Anyway, check out the video, embedded below and linked to above:</p>

-høring</a> om
-<a href="http://standard.difi.no/forvaltningsstandarder">referansekatalogen
-for IT-standarder i offentlig sektor</a>, med høringsfrist 2012-09-30
-(DIFI-sak 2012/498), ble det foreslått å fjerne ODF som obligatorisk
-standard når en publiserte dokumenter som skulle kunne redigeres
-videre av mottaker. NUUG og andre protesterte på forslaget, som er et
-langt steg tilbake når det gjelder å sikre like rettigheter for alle
-når en kommuniserer med det offentlige. For noen dager siden ble jeg
-oppmerksom på at Direktoratet for forvaltning og IKT (DIFI) og
-Fornyings-,administrasjons- og kirkedepartementet (FAD) har
-konkludert, og oversendt forslag til regjeringen i saken. FADs
-dokument

-«Utkast til endring av standardiseringsforskriften» datert 2013-02-06
-har følgende triste oppsummering fra høringen i saken:</p>
-
-<p><blockquote>
-Det kom noen innvendinger på forslaget om å fjerne ODF som
-obligatorisk standard for redigerbare dokumenter. Innvendingene har
-ikke blitt ilagt avgjørende vekt.
-</blockquote></p>
-
-<p>Ved å fjerne ODF som obligatorisk format ved publisering av
-redigerbare dokumenter setter en Norge tiår tilbake. Det som vil skje
-er at offentlige etater går tilbake til kun å publisere dokumenter på
-et av de mange formatene til Microsoft Office, og alle som ikke
-aksepterer bruksvilkårene til Microsoft eller ikke har råd til å bruke
-penger på å få tilgang til Microsoft Office må igjen basere seg på
-verktøy fra utviklerne som er avhengig av å reversutvikle disse
-formatene. I og med at ISO-spesifikasjonen for OOXML ikke komplett og
-korrekt spesifiserer formatene til MS Office (men er nyttige å titte i
-når en reversutvikler), er en tilbake til en situasjon der en ikke har
-<a href="http://people.skolelinux.org/pere/blog/Fri_og__pen_standard__slik_Digistan_ser_det.html">en
-fri og åpen standard</a> å forholde seg til, men i stedet må springe
-etter Microsoft. Alle andre leverandører enn Microsoft vil dermed ha
-en seriøs ulempe. Det er som å fjerne krav om bruk av meter som
-måleenhet, og heretter aksepterer alle måleenheter som like gyldige,
-når en vet at den mest brukte enheten vil være armlengden til Steve
-Ballmer slik Microsoft måler den.</p>
-
-<p>Jeg er ikke sikker på om forslaget er vedtatt av regjeringen ennå.
-Kristian Bergem hos DIFI nevnte på et møte forrige tirsdag at han
-trodde det var vedtatt i statsråd 8. mars, men jeg har ikke klart å
-finne en skriftlig kilde på regjeringen.no som bekrefter dette.
-Kanskje det ennå ikke er for sent...</p>
-
-<p>Jeg ba i forrige uke om innsyn i dokument 6, 7 og 8 i FAD-saken, og
-har i dag fått innsyn i dokument 7 og 8. Ble nektet innsyn i
-dokumentet med tittelen «Oppsummering av høring om endringer i
-forskrift om IT-standarder i offentlig forvaltning» med hjemmel i
-off. lovens §15.1, så det er vanskelig å vite hvordan argumentene fra
-høringen ble mottatt og forstått av saksbehandleren hos DIFI. Lurer
-på hvordan jeg kan klage på at jeg ikke fikk se oppsummeringen. Fikk
-tre PDFer tilsendt fra FAD,

- <div class="body"><p>Via
-<a href="https://twitter.com/pcwizz/status/313044373262716930">twitter</a>
-I just discovered that <a href="http://pcwizz.net/">Pcwizz</a> have
-done a <a href="http://www.youtube.com/watch?v=wPzTZ61Pcuc">video
-review</a> on Youtube of <a href="http://www.skolelinux.org/">Skolelinux
-/ Debian Edu</a> version 6. He installed the standalone profile and
-the video show a walk-through of of the menu content, demonstration of
-a few programs and his view of our distribution.</p>
-
-<p>There is also some really nice quotes (transcribed by me, might
-have heard wrong). While looking thought the Graphics menu:</p>
-
-<blockquote>
-"Basically everything you ever need in a school environment."
-</blockquote>
-
-<p>And as a general evaluation of the entire distribution:</p>
-
-<blockquote>
-"So, yeah, a bit bloated. It kept all the Debian stuff in there, just
-to keep it nice and GNU. So, I do not want to go on about it, but
-lets give it 7 out of 10. I am not going to use it. That is because
-I am not deploying a school network. There may be some mythical
-feature to help you deploy Skolelinux on a school network."
-</blockquote>
-
-<p>To bad he did not test the server profile, and discovered the PXE
-installation option. It make it possible to install only the main
-server from CD, and the rest of the machines via the net, and might be
-considered the mythical feature he talk about. :)</p>
-
-<p>While looking through the menus, there is also this funny comment
-about the part of the K menu generated from the Debian menu subsystem:
-
-<blockquote>
-"[The K menu] have a special Debian section for software that no-one
-is going to look at, because it contain lots of junky stuff that you
-actually don't need in the education distribution, but have just been
-included because it isn't stripped out for some reason."
-</blockquote>
-
-<p>I guess it is yet another argument for merging the Debian menu and
-Gnome/KDE desktop menu entries into
-<a href="http://wiki.debian.org/Proposals/DebianMenuUsingDesktopEntries">one
-consistent menu system</a> instead of two incomplete and partly
-inconsistent menu systems.</p>
