  24       <div class="date">22nd November 2013</div>
  25       <div class="body"><p>I fjor sommer lagde jeg en
  26 <a href="http://people.skolelinux.org/pere/blog/SQL_database_med_anbud_publisert_p__Doffin.html">offentlig
  27 tilgjengelig SQL-database over offentlig anbud</a> basert på skraping
  28 av HTML-data fra Doffin.  Den har stått og gått siden da, og har nå
  29 ca. 28000 oppføringer.  Jeg oppdaget da jeg tittet innom at noen
  30 oppføringer var ikke blitt med, antagelig på grunn av at de fikk
  31 tildelt sekvensnummer i Doffin en godt stund før de ble publisert,
  32 slik at min nettsideskraper som fortsatte skrapingen der den slapp
  33 sist ikke fikk dem med seg.  Jeg har fikset litt slik at skraperen nå
  34 ser litt tilbake i tid for å se om den har gått glipp av noen
  35 oppføringer, og har skrapet på nytt fra midten av september 2013 og
  36 fremover.  Det bør dermed bli en mer komplett database for kommende
  37 måneder.  Hvis jeg får tid skal jeg forsøke å skrape "glemte" data fra
  38 før midten av september 2013, men tør ikke garantere at det blir
  39 prioritert med det første. </p>
  40
  41 <p>Men målet med denne bloggposten er å vise hvordan denne
  42 Doffin-databasen kan brukes og integreres med en RSS-leser, slik at en
  43 kan la datamaskinen holde et øye med Doffin-annonseringer etter
  44 nøkkelord.  En kan lage sitt eget søk ved å besøke
  45 <ahref="https://classic.scraperwiki.com/docs/api?name=norwegian-doffin#sqlite">API-et
  46 hos Scraperwiki</a>, velge format rss2 og så legge inn noe ala dette i
  47 "query in SQL":</p>
  48
  49 <p><pre>
  50 select title, scrapedurl as link, abstract as description,
  51        publishdate as pubDate from 'swdata'
  52    where abstract like '%linux%' or title like '%linux%'
  53    order by seq desc limit 20
  54 </pre></p>
  55
  56 <p>Dette vil søke opp alle anbud med ordet linux i oppsummering eller
  57 tittel.  En kan lage mer avanserte søk hvis en ønsker det.  URL-en som
  58 dukker opp nederst på siden kan en så gi til sin RSS-leser (jeg bruker
  59 akregator selv), og så automatisk få beskjed hvis det dukker opp anbud
  60 med det aktuelle nøkkelordet i teksten.  Merk at kapasiteten hos
  61 Scraperwiki er begrenset, så be RSS-leseren kun hente ned en gang hver
  62 dag eller noe slikt.</p>
  63
  64 <p>Du lurer kanskje på hva slags informasjon en kan få ut fra denne
  65 databasen.  Her er to RSS-kilder, med søkeordet
  66 "<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>",

  72 Det er bare å søke på det en er interessert i.  Kopier gjerne
  73 datasettet og sett opp din egen tjeneste hvis du vil gjøre mer
  74 avanserte søk.  SQLite-filen med Doffin-oppføringer kan lastes med fra
  75 Scraperwiki for de som vil grave dypere.</p>

  90       <div class="date">21st November 2013</div>
  91       <div class="body">Drones, flying robots, are getting more and more popular.  The most
  92 know ones are the killer drones used by some government to murder
  93 people they do not like without giving them the chance of a fair
  94 trial, but the technology have many good uses too, from mapping and
  95 forest maintenance to photography and search and rescue.  I am sure it
  96 is just a question of time before "bad drones" are in the hands of
  97 private enterprises and not only state criminals but petty criminals
  98 too.  The drone technology is very useful and very dangerous.  To have
  99 some control over the use of drones, I agree with Daniel Suarez in his
 100 TED talk
 101 "<a href="https://archive.org/details/DanielSuarez_2013G">The kill
 102 decision shouldn't belong to a robot</a>", where he suggested this
 103 little gem to keep the good while limiting the bad use of drones:</p>
 104
 105 <blockquote>
 106
 107 <p>Each robot and drone should have a cryptographically signed
 108 I.D. burned in at the factory that can be used to track its movement
 109 through public spaces. We have license plates on cars, tail numbers on
 110 aircraft. This is no different. And every citizen should be able to
 111 download an app that shows the population of drones and autonomous
 112 vehicles moving through public spaces around them, both right now and
 113 historically. And civic leaders should deploy sensors and civic drones
 114 to detect rogue drones, and instead of sending killer drones of their
 115 own up to shoot them down, they should notify humans to their
 116 presence. And in certain very high-security areas, perhaps civic
 117 drones would snare them and drag them off to a bomb disposal facility.</p>
 118
 119 <p>But notice, this is more an immune system than a weapons system. It
 120 would allow us to avail ourselves of the use of autonomous vehicles
 121 and drones while still preserving our open, civil society.</p>
 122
 123 </blockquote>
 124
 125 <p>The key is that <em>every citizen</em> should be able to read the
 126 radio beacons sent from the drones in the area, to be able to check
 127 both the government and others use of drones.  For such control to be
 128 effective, everyone must be able to do it.  What should such beacon
 129 contain?  At least formal owner, purpose, contact information and GPS
 130 location.  Probably also the origin and target position of the current
 131 flight.  And perhaps some registration number to be able to look up
 132 the drone in a central database tracking their movement.  Robots
 133 should not have privacy.  It is people who need privacy.</p>

 174       <div class="date">10th November 2013</div>
 175       <div class="body"><p>Continuing my research into mesh networking, I was recommended to
 176 use TP-Link 3040 and 3600 access points as mesh nodes, and the pair I
 177 bought arrived on Friday.  Here are my notes on how to set up the
 178 MR3040 as a mesh node using
 179 <a href="http://www.openwrt.org/">OpenWrt</a>.</p>
 180
 181 <p>I started by following the instructions on the OpenWRT wiki for
 182 <a href="http://wiki.openwrt.org/toh/tp-link/tl-mr3040">TL-MR3040</a>,
 183 and downloaded
 184 <a href="http://downloads.openwrt.org/snapshots/trunk/ar71xx/openwrt-ar71xx-generic-tl-mr3040-v2-squashfs-factory.bin">the
 185 recommended firmware image</a>
 186 (openwrt-ar71xx-generic-tl-mr3040-v2-squashfs-factory.bin) and
 187 uploaded it into the original web interface.  The flashing went fine,
 188 and the machine was available via telnet on the ethernet port.  After
 189 logging in and setting the root password, ssh was available and I
 190 could start to set it up as a batman-adv mesh node.</p>
 191
 192 <p>I started off by reading the instructions from
 193 <a href="http://wirelessafrica.meraka.org.za/wiki/index.php?title=Antoine's_Research">Wireless
 194 Africa</a>, which had quite a lot of useful information, but
 195 eventually I followed the recipe from the Open Mesh wiki for
 196 <a href="http://www.open-mesh.org/projects/batman-adv/wiki/Batman-adv-openwrt-config">using
 197 batman-adv on OpenWrt</a>.  A small snag was the fact that the
 198 <tt>opkg install kmod-batman-adv</tt> command did not work as it
 199 should.  The batman-adv kernel module would fail to load because its
 200 dependency crc16 was not already loaded.  I
 201 <a href="https://dev.openwrt.org/ticket/14452">reported the bug</a> to
 202 the openwrt project and hope it will be fixed soon.  But the problem
 203 only seem to affect initial testing of batman-adv, as configuration
 204 seem to work when booting from scratch.</p>
 205
 206 <p>The setup is done using files in /etc/config/.  I did not bridge
 207 the Ethernet and mesh interfaces this time, to be able to hook up the
 208 box on my local network and log into it for configuration updates.
 209 The following files were changed and look like this after modifying
 210 them:</p>

 488 <p>It is based on /etc/init.d/skeleton, and could be improved quite a
 489 lot.  I did not really polish the approach, so it might not always
 490 work out of the box, but you get the idea.  I did not try very hard to
 491 optimize it nor make it more robust either.</p>
 492
 493 <p>A better argument for switching init system in Debian than reducing
 494 the size of init scripts (which is a good thing to do anyway), is to
 495 get boot system that is able to handle the kernel events sensibly and
 496 robustly, and do not depend on the boot to run sequentially.  The boot
 497 and the kernel have not behaved sequentially in years.</p>

 540       <div class="date">27th October 2013</div>
 541       <div class="body"><p>The
 542 <a href="http://packages.qa.debian.org/v/vmdebootstrap.html">vmdebootstrap</a>
 543 program is a a very nice system to create virtual machine images.  It
 544 create a image file, add a partition table, mount it and run
 545 debootstrap in the mounted directory to create a Debian system on a
 546 stick.  Yesterday, I decided to try to teach it how to make images for
 547 <a href="https://wiki.debian.org/RaspberryPi">Raspberry Pi</a>, as part
 548 of a plan to simplify the build system for
 549 <a href="https://wiki.debian.org/FreedomBox">the FreedomBox
 550 project</a>.  The FreedomBox project already uses vmdebootstrap for
 551 the virtualbox images, but its current build system made multistrap
 552 based system for Dreamplug images, and it is lacking support for
 553 Raspberry Pi.</p>
 554
 555 <p>Armed with the knowledge on how to build "foreign" (aka non-native
 556 architecture) chroots for Raspberry Pi, I dived into the vmdebootstrap
 557 code and adjusted it to be able to build armel images on my amd64
 558 Debian laptop.  I ended up giving vmdebootstrap five new options,
 559 allowing me to replicate the image creation process I use to make
 560 <a href="http://people.skolelinux.org/pere/blog/A_Raspberry_Pi_based_batman_adv_Mesh_network_node.html">Debian
 561 Jessie based mesh node images for the Raspberry Pi</a>.  First, the
 562 <tt>--foreign /path/to/binfm_handler</tt> option tell vmdebootstrap to
 563 call debootstrap with --foreign and to copy the handler into the
 564 generated chroot before running the second stage.  This allow
 565 vmdebootstrap to create armel images on an amd64 host.  Next I added
 566 two new options <tt>--bootsize size</tt> and <tt>--boottype
 567 fstype</tt> to teach it to create a separate /boot/ partition with the
 568 given file system type, allowing me to create an image with a vfat
 569 partition for the /boot/ stuff.  I also added a <tt>--variant
 570 variant</tt> option to allow me to create smaller images without the
 571 Debian base system packages installed.  Finally, I added an option
 572 <tt>--no-extlinux</tt> to tell vmdebootstrap to not install extlinux
 573 as a boot loader.  It is not needed on the Raspberry Pi and probably
 574 most other non-x86 architectures.  The changes were accepted by the
 575 upstream author of vmdebootstrap yesterday and today, and is now
 576 available from
 577 <a href="http://git.liw.fi/cgi-bin/cgit/cgit.cgi/vmdebootstrap/">the
 578 upstream project page</a>.</p>
 579
 580 <p>To use it to build a Raspberry Pi image using Debian Jessie, first
 581 create a small script (the customize script) to add the non-free
 582 binary blob needed to boot the Raspberry Pi and the APT source
 583 list:</p>
 584
 585 <p><pre>
 586 #!/bin/sh
 587 set -e # Exit on first error
 588 rootdir="$1"
 589 cd "$rootdir"
 590 cat &lt;&lt;EOF > etc/apt/sources.list
 591 deb http://http.debian.net/debian/ jessie main contrib non-free
 592 EOF
 593 # Install non-free binary blob needed to boot Raspberry Pi.  This
 594 # install a kernel somewhere too.
 595 wget https://raw.github.com/Hexxeh/rpi-update/master/rpi-update \
 596     -O $rootdir/usr/bin/rpi-update
 597 chmod a+x $rootdir/usr/bin/rpi-update
 598 mkdir -p $rootdir/lib/modules
 599 touch $rootdir/boot/start.elf
 600 chroot $rootdir rpi-update
 601 </pre></p>
 602
 603 <p>Next, fetch the latest vmdebootstrap script and call it like this
 604 to build the image:</p>
 605
 606 <pre>
 607 sudo ./vmdebootstrap \
 608     --variant minbase \
 609     --arch armel \
 610     --distribution jessie \
 611     --mirror http://http.debian.net/debian \
 612     --image test.img \
 613     --size 600M \
 614     --bootsize 64M \
 615     --boottype vfat \
 616     --log-level debug \
 617     --verbose \
 618     --no-kernel \
 619     --no-extlinux \
 620     --root-password raspberry \
 621     --hostname raspberrypi \
 622     --foreign /usr/bin/qemu-arm-static \
 623     --customize `pwd`/customize \
 624     --package netbase \
 625     --package git-core \
 626     --package binutils \
 627     --package ca-certificates \
 628     --package wget \
 629     --package kmod
 630 </pre></p>
 631
 632 <p>The list of packages being installed are the ones needed by
 633 rpi-update to make the image bootable on the Raspberry Pi, with the
 634 exception of netbase, which is needed by debootstrap to find
 635 /etc/hosts with the minbase variant.  I really wish there was a way to
 636 set up an Raspberry Pi using only packages in the Debian archive, but
 637 that is not possible as far as I know, because it boots from the GPU
 638 using a non-free binary blob.</p>
 639
 640 <p>The build host need debootstrap, kpartx and qemu-user-static and
 641 probably a few others installed.  I have not checked the complete
 642 build dependency list.</p>
 643
 644 <p>The resulting image will not use the hardware floating point unit
 645 on the Raspberry PI, because the armel architecture in Debian is not
 646 optimized for that use.  So the images created will be a bit slower
 647 than <a href="http://www.raspbian.org/">Raspbian</a> based images.</p>

 661       <div class="date">26th October 2013</div>

 664 totale overvåkningen som foregår i den vestlige verden dokumenterer
 665 hvor sårbare vi er</a>.  Men det slår meg at de som er mest sårbare
 666 for dette, myndighetspersoner på alle nivåer, neppe har innsett at de
 667 selv er de mest interessante personene å lage profiler på, for å kunne
 668 påvirke dem.</p>
 669
 670 <p>For å ta et lite eksempel: Stortingets nettsted,
 671 <a href="http://www.stortinget.no/">www.stortinget.no</a> (og
 672 forsåvidt også
 673 <a href="http://data.stortinget.no/">data.stortinget.no</a>),
 674 inneholder informasjon om det som foregår på Stortinget, og jeg antar
 675 de største brukerne av informasjonen der er representanter og
 676 rådgivere på Stortinget.  Intet overraskende med det.  Det som derimot
 677 er mer skjult er at Stortingets nettsted bruker
 678 <a href="http://en.wikipedia.org/wiki/Google_Analytics">Google
 679 Analytics</a>, hvilket gjør at enhver som besøker nettsidene der også
 680 rapporterer om besøket via Internett-linjer som passerer Sverige,
 681 England og videre til USA.  Det betyr at informasjon om ethvert besøk
 682 på stortingets nettsider kan snappes opp av svensk, britisk og USAs
 683 etterretningsvesen.  De kan dermed holde et øye med hvilke
 684 Stortingssaker stortingsrepresentantene synes er interessante å sjekke
 685 ut, og hvilke sider rådgivere og andre på stortinget synes er
 686 interessant å besøke, når de gjør det og hvilke andre representanter
 687 som sjekker de samme sidene omtrent samtidig.  Stortingets bruk av
 688 Google Analytics gjør det dermed enkelt for utenlands etteretning å
 689 spore representantenes aktivitet og interesse.  Hvis noen av
 690 representantene bruker Google Mail eller noen andre tjenestene som
 691 krever innlogging, så vil det være enda enklere å finne ut nøyaktig
 692 hvilke personer som bruker hvilke nettlesere og dermed knytte
 693 informasjonen opp til enkeltpersoner på Stortinget.</p>
 694
 695 <p>Og jo flere nettsteder som bruker Google Analytics, jo bedre
 696 oversikt over stortingsrepresentantenes lesevaner og interesse blir
 697 tilgjengelig for svensk, britisk og USAs etterretning.  Hva de kan
 698 bruke den informasjonen til overlater jeg til leseren å undres
 699 over.</p>

 713       <div class="date">21st October 2013</div>
 714       <div class="body"><p>The last few days I have been experimenting with
 715 <a href="http://www.open-mesh.org/projects/batman-adv/wiki">the
 716 batman-adv mesh technology</a>.  I want to gain some experience to see
 717 if it will fit <a href="https://wiki.debian.org/FreedomBox">the
 718 Freedombox project</a>, and together with my neighbors try to build a
 719 mesh network around the park where I live.  Batman-adv is a layer 2
 720 mesh system ("ethernet" in other words), where the mesh network appear
 721 as if all the mesh clients are connected to the same switch.</p>
 722
 723 <p>My hardware of choice was the Linksys WRT54GL routers I had lying
 724 around, but I've been unable to get them working with batman-adv.  So
 725 instead, I started playing with a
 726 <a href="http://www.raspberrypi.org/">Raspberry Pi</a>, and tried to
 727 get it working as a mesh node.  My idea is to use it to create a mesh
 728 node which function as a switch port, where everything connected to
 729 the Raspberry Pi ethernet plug is connected (bridged) to the mesh
 730 network.  This allow me to hook a wifi base station like the Linksys
 731 WRT54GL to the mesh by plugging it into a Raspberry Pi, and allow
 732 non-mesh clients to hook up to the mesh.  This in turn is useful for
 733 Android phones using <a href="http://servalproject.org/">the Serval
 734 Project</a> voip client, allowing every one around the playground to
 735 phone and message each other for free.  The reason is that Android
 736 phones do not see ad-hoc wifi networks (they are filtered away from
 737 the GUI view), and can not join the mesh without being rooted.  But if
 738 they are connected using a normal wifi base station, they can talk to
 739 every client on the local network.</p>
 740
 741 <p>To get this working, I've created a debian package
 742 <a href="https://github.com/petterreinholdtsen/meshfx-node">meshfx-node</a>
 743 and a script
 744 <a href="https://github.com/petterreinholdtsen/meshfx-node/blob/master/build-rpi-mesh-node">build-rpi-mesh-node</a>
 745 to create the Raspberry Pi boot image.  I'm using Debian Jessie (and
 746 not Raspbian), to get more control over the packages available.
 747 Unfortunately a huge binary blob need to be inserted into the boot
 748 image to get it booting, but I'll ignore that for now.  Also, as
 749 Debian lack support for the CPU features available in the Raspberry
 750 Pi, the system do not use the hardware floating point unit.  I hope
 751 the routing performance isn't affected by the lack of hardware FPU
 752 support.</p>
 753
 754 <p>To create an image, run the following with a sudo enabled user
 755 after inserting the target SD card into the build machine:</p>
 756
 757 <p><pre>
 758 % wget -O build-rpi-mesh-node \
 759     https://raw.github.com/petterreinholdtsen/meshfx-node/master/build-rpi-mesh-node
 760 % sudo bash -x ./build-rpi-mesh-node > build.log 2>&1
 761 % dd if=/root/rpi/rpi_basic_jessie_$(date +%Y%m%d).img of=/dev/mmcblk0 bs=1M
 762 %
 763 </pre></p>
 764
 765 <p>Booting with the resulting SD card on a Raspberry PI with a USB
 766 wifi card inserted should give you a mesh node.  At least it does for
 767 me with a the wifi card I am using. The default mesh settings are the
 768 ones used by the Oslo mesh project at Hackeriet, as I mentioned in
 769 <a href="http://people.skolelinux.org/pere/blog/Oslo_community_mesh_network___with_NUUG_and_Hackeriet_at_Hausmania.html">an
 770 earlier blog post about this mesh testing</a>.</p>
 771
 772 <p>The mesh node was not horribly expensive either.  I bought
 773 everything over the counter in shops nearby.  If I had ordered online
 774 from the lowest bidder, the price should be significantly lower:</p>
 775
 776 <p><table>
 777
 778 <tr><th>Supplier</th><th>Model</th><th>NOK</th></tr>
 779 <tr><td>Teknikkmagasinet</td><td>Raspberry Pi model B</td><td>349.90</td></tr>
 780 <tr><td>Teknikkmagasinet</td><td>Raspberry Pi type B case</td><td>99.90</td></tr>
 781 <tr><td>Lefdal</td><td>Jensen Air:Link 25150</td><td>295.-</td></tr>
 782 <tr><td>Clas Ohlson</td><td>Kingston 16 GB SD card</td><td>199.-</td></tr>
 783 <tr><td>Total cost</td><td></td><td>943.80</td></tr>
 784
 785 </table></p>
 786
 787 <p>Now my mesh network at home consist of one laptop in the basement
 788 connected to my production network, one Raspberry Pi node on the 1th
 789 floor that can be seen by my neighbor across the park, and one
 790 play-node I use to develop the image building script.  And some times
 791 I hook up my work horse laptop to the mesh to test it.  I look forward
 792 to figuring out what kind of latency the batman-adv setup will give,
 793 and how much packet loss we will experience around the park. :)</p>

 808       <div class="body"><p>Back in 2010, I created a Perl library to talk to
 809 <a href="http://en.wikipedia.org/wiki/Spykee">the Spykee robot</a>
 810 (with two belts, wifi, USB and Linux) and made it available from my
 811 web page.  Today I concluded that it should move to a site that is
 812 easier to use to cooperate with others, and moved it to github.  If
 813 you got a Spykee robot, you might want to check out
 814 <a href="https://github.com/petterreinholdtsen/libspykee-perl">the
