25 <div class="body"><p>If you want the ability to electronically communicate directly with
26 your neighbors and friends using a network controlled by your peers in
27 stead of centrally controlled by a few corporations, or would like to
28 experiment with interesting network technology, the
29 <a href="http://www.dugnadsnett.no/">Dugnasnett for alle i Oslo</a>
30 might be project for you. 39 mesh nodes are currently being planned,
31 in the freshly started initiative from NUUG and Hackeriet to create a
32 wireless community network. The work is inspired by
33 <a href="http://freifunk.net/">Freifunk</a>,
34 <a href="http://www.awmn.net/">Athens Wireless Metropolitan
35 Network</a>, <a href="http://en.wikipedia.org/wiki/Roofnet">Roofnet</a>
36 and other successful mesh networks around the globe. Two days ago we
37 held a workshop to try to get people started on setting up their own
38 mesh node, and there we decided to create a new mailing list
39 <a href="http://lists.nuug.no/mailman/listinfo/dugnadsnett">dugnadsnett
40 (at) nuug.no</a> and IRC channel
41 <a href="irc://irc.freenode.net/#dugnadsnett.no">#dugnadsnett.no</a> to
42 coordinate the work. See also the NUUG blog post

103 <p>Prosjektledelsen har fortalt at dette skal fungere like godt for
104 Linux-brukere som for brukere av Microsoft Windows og Apple MacOSX,
105 men jeg lurer på hva slags erfaringer Linux-brukere i eksisterende
106 miljøer som bruker MS Exchange har gjort. Hvis du har slik erfaring
107 hadet det vært veldig fint om du kan send et leserbrev til
108 <a href="http://www.uniforum.uio.no/">Uniforum</a> og fortelle om hvor
109 greit det er å bruke Exchange i kryss-platform-miljøer? De jeg har
110 snakket med sier en greit får lest e-posten sin hvis Exchange har
111 slått på IMAP-funksjonalitet, men at kalender og møtebooking ikke
112 fungerer godt for Linux-klienter. Jeg har ingen personlig erfaring å
113 komme med, så jeg er nysgjerrig på hva andre kan dele av erfaringer
114 med universitetet.</p>
115
116 <p>Mitt ankerpunkt mot å bytte ut fri programvare som fungerer godt
117 med godseid programvare er at en mister kontroll over egen
118 infrastruktur, låser seg inn i en løsning det vil bli dyrt å komme ut
119 av, uten at en får funksjonalitet en ikke kunne skaffet seg med fri
120 programvare, eventuelt videreutviklet med de pengene som brukes på
121 overgangen til MS Exchange. Personlig planlegger jeg å fortsette å
122 laste ned all eposten min til lokal maskin for indeksering og lesing
123 med <a href=="http://notmuchmail.org">notmuch</a>, så jeg håper jeg
124 ikke blir veldig skadelidende av overgangen.</p>

143 <div class="date">24th November 2013</div>
144 <div class="body"><p>After many years break from the package and a vain hope that
145 development would be continued by someone else, I finally pulled my
146 acts together this morning and wrapped up a new release of chrpath,
147 the command line tool to modify the rpath and runpath of already
148 compiled ELF programs. The update was triggered by the persistence of
149 Isha Vishnoi at IBM, which needed a new config.guess file to get
150 support for the ppc64le architecture (powerpc 64-bit Little Endian) he
151 is working on. I checked the
152 <a href="http://packages.qa.debian.org/chrpath">Debian</a>,
153 <a href="https://launchpad.net/ubuntu/+source/chrpath">Ubuntu</a> and
154 <a href="https://admin.fedoraproject.org/pkgdb/acls/name/chrpath">Fedora</a>
155 packages for interesting patches (failed to find the source from
156 OpenSUSE and Mandriva packages), and found quite a few nice fixes.
157 These are the release notes:</p>
158
159 <p>New in 0.15 released 2013-11-24:</p>
160
161 <ul>
162
163 <li>Updated config.sub and config.guess from the GNU project to work
164 with newer architectures. Thanks to isha vishnoi for the heads
165 up.</li>
166
167 <li>Updated README with current URLs.</li>
168
169 <li>Added byteswap fix found in Ubuntu, credited Jeremy Kerr and
170 Matthias Klose.</li>
171
172 <li>Added missing help for -k|--keepgoing option, using patch by
173 Petr Machata found in Fedora.</li>
174
175 <li>Rewrite removal of RPATH/RUNPATH to make sure the entry in
176 .dynamic is a NULL terminated string. Based on patch found in
177 Fedora credited Axel Thimm and Christian Krause.</li>

200 <div class="date">22nd November 2013</div>
201 <div class="body"><p>I fjor sommer lagde jeg en
202 <a href="http://people.skolelinux.org/pere/blog/SQL_database_med_anbud_publisert_p__Doffin.html">offentlig
203 tilgjengelig SQL-database over offentlig anbud</a> basert på skraping
204 av HTML-data fra Doffin. Den har stått og gått siden da, og har nå
205 ca. 28000 oppføringer. Jeg oppdaget da jeg tittet innom at noen
206 oppføringer var ikke blitt med, antagelig på grunn av at de fikk
207 tildelt sekvensnummer i Doffin en godt stund før de ble publisert,
208 slik at min nettsideskraper som fortsatte skrapingen der den slapp
209 sist ikke fikk dem med seg. Jeg har fikset litt slik at skraperen nå
210 ser litt tilbake i tid for å se om den har gått glipp av noen
211 oppføringer, og har skrapet på nytt fra midten av september 2013 og
212 fremover. Det bør dermed bli en mer komplett database for kommende
213 måneder. Hvis jeg får tid skal jeg forsøke å skrape "glemte" data fra
214 før midten av september 2013, men tør ikke garantere at det blir
215 prioritert med det første. </p>
216
217 <p>Men målet med denne bloggposten er å vise hvordan denne
218 Doffin-databasen kan brukes og integreres med en RSS-leser, slik at en
219 kan la datamaskinen holde et øye med Doffin-annonseringer etter
220 nøkkelord. En kan lage sitt eget søk ved å besøke
221 <ahref="https://classic.scraperwiki.com/docs/api?name=norwegian-doffin#sqlite">API-et
222 hos Scraperwiki</a>, velge format rss2 og så legge inn noe ala dette i
223 "query in SQL":</p>
224
225 <p><pre>
226 select title, scrapedurl as link, abstract as description,
227 publishdate as pubDate from 'swdata'
228 where abstract like '%linux%' or title like '%linux%'
229 order by seq desc limit 20
230 </pre></p>
231
232 <p>Dette vil søke opp alle anbud med ordet linux i oppsummering eller
233 tittel. En kan lage mer avanserte søk hvis en ønsker det. URL-en som
234 dukker opp nederst på siden kan en så gi til sin RSS-leser (jeg bruker
235 akregator selv), og så automatisk få beskjed hvis det dukker opp anbud
236 med det aktuelle nøkkelordet i teksten. Merk at kapasiteten og
237 ytelsen hos Scraperwiki er begrenset, så ikke be RSS-leseren hente ned
238 oftere enn en gang hver dag.</p>
239
240 <p>Du lurer kanskje på hva slags informasjon en kan få ut fra denne
241 databasen. Her er to RSS-kilder, med søkeordet
242 "<a href="https://api.scraperwiki.com/api/1.0/datastore/sqlite?format=rss2&name=norwegian-doffin&query=select%20title%2C%20scrapedurl%20as%20link%2C%20abstract%20as%20description%2C%0A%20%20%20%20%20%20%20publishdate%20as%20pubDate%20from%20'swdata'%0A%20%20%20where%20abstract%20like%20'%25linux%25'%20or%20title%20like%20'%25linux%25'%0A%20%20%20order%20by%20seq%20desc%20limit%2020">linux</a>",

245 programvare</a>"
246 og søkeordet
247 "<a href="https://api.scraperwiki.com/api/1.0/datastore/sqlite?format=rss2&name=norwegian-doffin&query=select%20title%2C%20scrapedurl%20as%20link%2C%20abstract%20as%20description%2C%0A%20%20%20%20%20%20%20publishdate%20as%20pubDate%20from%20'swdata'%0A%20%20%20where%20abstract%20like%20'%25odf%25'%20or%20title%20like%20'%25odf%25'%0A%20%20%20order%20by%20seq%20desc%20limit%2020">odf</a>".
248 Det er bare å søke på det en er interessert i. Kopier gjerne
249 datasettet og sett opp din egen tjeneste hvis du vil gjøre mer
250 avanserte søk. SQLite-filen med Doffin-oppføringer kan lastes med fra
251 Scraperwiki for de som vil grave dypere.</p>

265 <div class="date">21st November 2013</div>
266 <div class="body"><p>Drones, flying robots, are getting more and more popular. The most
267 know ones are the killer drones used by some government to murder
268 people they do not like without giving them the chance of a fair
269 trial, but the technology have many good uses too, from mapping and
270 forest maintenance to photography and search and rescue. I am sure it
271 is just a question of time before "bad drones" are in the hands of
272 private enterprises and not only state criminals but petty criminals
273 too. The drone technology is very useful and very dangerous. To have
274 some control over the use of drones, I agree with Daniel Suarez in his
275 TED talk
276 "<a href="https://archive.org/details/DanielSuarez_2013G">The kill
277 decision shouldn't belong to a robot</a>", where he suggested this
278 little gem to keep the good while limiting the bad use of drones:</p>
279
280 <blockquote>
281
282 <p>Each robot and drone should have a cryptographically signed
283 I.D. burned in at the factory that can be used to track its movement
284 through public spaces. We have license plates on cars, tail numbers on
285 aircraft. This is no different. And every citizen should be able to
286 download an app that shows the population of drones and autonomous
287 vehicles moving through public spaces around them, both right now and
288 historically. And civic leaders should deploy sensors and civic drones
289 to detect rogue drones, and instead of sending killer drones of their
290 own up to shoot them down, they should notify humans to their
291 presence. And in certain very high-security areas, perhaps civic
292 drones would snare them and drag them off to a bomb disposal facility.</p>
293
294 <p>But notice, this is more an immune system than a weapons system. It
295 would allow us to avail ourselves of the use of autonomous vehicles
296 and drones while still preserving our open, civil society.</p>
297
298 </blockquote>
299
300 <p>The key is that <em>every citizen</em> should be able to read the
301 radio beacons sent from the drones in the area, to be able to check
302 both the government and others use of drones. For such control to be
303 effective, everyone must be able to do it. What should such beacon
304 contain? At least formal owner, purpose, contact information and GPS
305 location. Probably also the origin and target position of the current
306 flight. And perhaps some registration number to be able to look up
307 the drone in a central database tracking their movement. Robots
308 should not have privacy. It is people who need privacy.</p>

349 <div class="date">10th November 2013</div>
350 <div class="body"><p>Continuing my research into mesh networking, I was recommended to
351 use TP-Link 3040 and 3600 access points as mesh nodes, and the pair I
352 bought arrived on Friday. Here are my notes on how to set up the
353 MR3040 as a mesh node using
354 <a href="http://www.openwrt.org/">OpenWrt</a>.</p>
355
356 <p>I started by following the instructions on the OpenWRT wiki for
357 <a href="http://wiki.openwrt.org/toh/tp-link/tl-mr3040">TL-MR3040</a>,
358 and downloaded
359 <a href="http://downloads.openwrt.org/snapshots/trunk/ar71xx/openwrt-ar71xx-generic-tl-mr3040-v2-squashfs-factory.bin">the
360 recommended firmware image</a>
361 (openwrt-ar71xx-generic-tl-mr3040-v2-squashfs-factory.bin) and
362 uploaded it into the original web interface. The flashing went fine,
363 and the machine was available via telnet on the ethernet port. After
364 logging in and setting the root password, ssh was available and I
365 could start to set it up as a batman-adv mesh node.</p>
366
367 <p>I started off by reading the instructions from
368 <a href="http://wirelessafrica.meraka.org.za/wiki/index.php?title=Antoine's_Research">Wireless

370 eventually I followed the recipe from the Open Mesh wiki for
371 <a href="http://www.open-mesh.org/projects/batman-adv/wiki/Batman-adv-openwrt-config">using
372 batman-adv on OpenWrt</a>. A small snag was the fact that the
373 <tt>opkg install kmod-batman-adv</tt> command did not work as it
374 should. The batman-adv kernel module would fail to load because its
375 dependency crc16 was not already loaded. I
376 <a href="https://dev.openwrt.org/ticket/14452">reported the bug</a> to
377 the openwrt project and hope it will be fixed soon. But the problem
378 only seem to affect initial testing of batman-adv, as configuration
379 seem to work when booting from scratch.</p>
380
381 <p>The setup is done using files in /etc/config/. I did not bridge
382 the Ethernet and mesh interfaces this time, to be able to hook up the
383 box on my local network and log into it for configuration updates.

483 <a href="http://thomas.goirand.fr/blog/?p=147">to get rid of huge
484 init.d scripts</a>, I doubt we need to switch away from sysvinit and
485 init.d scripts at all. Here is an example init.d script, ie a rewrite

663 <p>It is based on /etc/init.d/skeleton, and could be improved quite a
664 lot. I did not really polish the approach, so it might not always
665 work out of the box, but you get the idea. I did not try very hard to
666 optimize it nor make it more robust either.</p>
667
668 <p>A better argument for switching init system in Debian than reducing
669 the size of init scripts (which is a good thing to do anyway), is to
670 get boot system that is able to handle the kernel events sensibly and
671 robustly, and do not depend on the boot to run sequentially. The boot
672 and the kernel have not behaved sequentially in years.</p>

688 remote display access is the preferred solution with oVirt and RedHat

691 missing in Debian. The <a href="http://bugs.debian.org/668284">request
692 for a package</a> was from 2012-04-10 with no progress since
693 2013-04-01, so I decided to wrap up a package based on the great work
694 from Cajus Pollmeier and put it in a collab-maint maintained git
695 repository to get a package I could use. I would very much like
696 others to help me maintain the package (or just take over, I do not
697 mind), but as no-one had volunteered so far, I just uploaded it to
698 NEW. I hope it will be available in Debian in a few days.</p>

715 <div class="date">27th October 2013</div>
716 <div class="body"><p>The
717 <a href="http://packages.qa.debian.org/v/vmdebootstrap.html">vmdebootstrap</a>
718 program is a a very nice system to create virtual machine images. It
719 create a image file, add a partition table, mount it and run
720 debootstrap in the mounted directory to create a Debian system on a
721 stick. Yesterday, I decided to try to teach it how to make images for
722 <a href="https://wiki.debian.org/RaspberryPi">Raspberry Pi</a>, as part
723 of a plan to simplify the build system for
724 <a href="https://wiki.debian.org/FreedomBox">the FreedomBox
725 project</a>. The FreedomBox project already uses vmdebootstrap for
726 the virtualbox images, but its current build system made multistrap
727 based system for Dreamplug images, and it is lacking support for
728 Raspberry Pi.</p>
729
730 <p>Armed with the knowledge on how to build "foreign" (aka non-native
731 architecture) chroots for Raspberry Pi, I dived into the vmdebootstrap
732 code and adjusted it to be able to build armel images on my amd64
733 Debian laptop. I ended up giving vmdebootstrap five new options,
734 allowing me to replicate the image creation process I use to make
735 <a href="http://people.skolelinux.org/pere/blog/A_Raspberry_Pi_based_batman_adv_Mesh_network_node.html">Debian
736 Jessie based mesh node images for the Raspberry Pi</a>. First, the
737 <tt>--foreign /path/to/binfm_handler</tt> option tell vmdebootstrap to
738 call debootstrap with --foreign and to copy the handler into the
739 generated chroot before running the second stage. This allow
740 vmdebootstrap to create armel images on an amd64 host. Next I added
741 two new options <tt>--bootsize size</tt> and <tt>--boottype
742 fstype</tt> to teach it to create a separate /boot/ partition with the
743 given file system type, allowing me to create an image with a vfat
744 partition for the /boot/ stuff. I also added a <tt>--variant
745 variant</tt> option to allow me to create smaller images without the
746 Debian base system packages installed. Finally, I added an option
747 <tt>--no-extlinux</tt> to tell vmdebootstrap to not install extlinux
748 as a boot loader. It is not needed on the Raspberry Pi and probably
749 most other non-x86 architectures. The changes were accepted by the
750 upstream author of vmdebootstrap yesterday and today, and is now
751 available from
752 <a href="http://git.liw.fi/cgi-bin/cgit/cgit.cgi/vmdebootstrap/">the
753 upstream project page</a>.</p>
754
755 <p>To use it to build a Raspberry Pi image using Debian Jessie, first
756 create a small script (the customize script) to add the non-free
757 binary blob needed to boot the Raspberry Pi and the APT source
758 list:</p>
759
760 <p><pre>
761 #!/bin/sh
762 set -e # Exit on first error
763 rootdir="$1"
764 cd "$rootdir"
765 cat &lt;&lt;EOF > etc/apt/sources.list
766 deb http://http.debian.net/debian/ jessie main contrib non-free
767 EOF
768 # Install non-free binary blob needed to boot Raspberry Pi. This
769 # install a kernel somewhere too.
770 wget https://raw.github.com/Hexxeh/rpi-update/master/rpi-update \
771 -O $rootdir/usr/bin/rpi-update
772 chmod a+x $rootdir/usr/bin/rpi-update
773 mkdir -p $rootdir/lib/modules
774 touch $rootdir/boot/start.elf
775 chroot $rootdir rpi-update
776 </pre></p>
777
778 <p>Next, fetch the latest vmdebootstrap script and call it like this
779 to build the image:</p>
780
781 <pre>
782 sudo ./vmdebootstrap \
783 --variant minbase \
784 --arch armel \
785 --distribution jessie \
786 --mirror http://http.debian.net/debian \
787 --image test.img \
788 --size 600M \
789 --bootsize 64M \
790 --boottype vfat \
791 --log-level debug \
792 --verbose \
793 --no-kernel \
794 --no-extlinux \
795 --root-password raspberry \
796 --hostname raspberrypi \
797 --foreign /usr/bin/qemu-arm-static \
798 --customize `pwd`/customize \
799 --package netbase \
800 --package git-core \
801 --package binutils \
802 --package ca-certificates \
803 --package wget \
804 --package kmod
805 </pre></p>
806
807 <p>The list of packages being installed are the ones needed by
808 rpi-update to make the image bootable on the Raspberry Pi, with the
809 exception of netbase, which is needed by debootstrap to find
810 /etc/hosts with the minbase variant. I really wish there was a way to
811 set up an Raspberry Pi using only packages in the Debian archive, but
812 that is not possible as far as I know, because it boots from the GPU
813 using a non-free binary blob.</p>
814
815 <p>The build host need debootstrap, kpartx and qemu-user-static and
816 probably a few others installed. I have not checked the complete
817 build dependency list.</p>
818
819 <p>The resulting image will not use the hardware floating point unit
820 on the Raspberry PI, because the armel architecture in Debian is not
821 optimized for that use. So the images created will be a bit slower
822 than <a href="http://www.raspbian.org/">Raspbian</a> based images.</p>
