  36 fri programvare- og åpne standardløsninger for å håndtere epost,
  37 vekk fra IETF-standarden SIEVE for filtrering av epost og over til
  38 godseide spesifikasjoner og epostsystemet Microsoft Exchange.
  39 Protestene har fått litt ny omtale i media de siste dagene, i tillegg

  76 <p>Prosjektledelsen har fortalt at dette skal fungere like godt for
  77 Linux-brukere som for brukere av Microsoft Windows og Apple MacOSX,
  78 men jeg lurer på hva slags erfaringer Linux-brukere i eksisterende
  79 miljøer som bruker MS Exchange har gjort.  Hvis du har slik erfaring
  80 hadet det vært veldig fint om du kan send et leserbrev til
  81 <a href="http://www.uniforum.uio.no/">Uniforum</a> og fortelle om hvor
  82 greit det er å bruke Exchange i kryss-platform-miljøer?  De jeg har
  83 snakket med sier en greit får lest e-posten sin hvis Exchange har
  84 slått på IMAP-funksjonalitet, men at kalender og møtebooking ikke
  85 fungerer godt for Linux-klienter. Jeg har ingen personlig erfaring å
  86 komme med, så jeg er nysgjerrig på hva andre kan dele av erfaringer
  87 med universitetet.</p>
  88
  89 <p>Mitt ankerpunkt mot å bytte ut fri programvare som fungerer godt
  90 med godseid programvare er at en mister kontroll over egen
  91 infrastruktur, låser seg inn i en løsning det vil bli dyrt å komme ut
  92 av, uten at en får funksjonalitet en ikke kunne skaffet seg med fri
  93 programvare, eventuelt videreutviklet med de pengene som brukes på
  94 overgangen til MS Exchange.  Personlig planlegger jeg å fortsette å
  95 laste ned all eposten min til lokal maskin for indeksering og lesing
  96 med <a href=="http://notmuchmail.org">notmuch</a>, så jeg håper jeg
  97 ikke blir veldig skadelidende av overgangen.</p>

 123         <p>After many years break from the package and a vain hope that
 124 development would be continued by someone else, I finally pulled my
 125 acts together this morning and wrapped up a new release of chrpath,
 126 the command line tool to modify the rpath and runpath of already
 127 compiled ELF programs.  The update was triggered by the persistence of
 128 Isha Vishnoi at IBM, which needed a new config.guess file to get
 129 support for the ppc64le architecture (powerpc 64-bit Little Endian) he
 130 is working on.  I checked the
 131 <a href="http://packages.qa.debian.org/chrpath">Debian</a>,
 132 <a href="https://launchpad.net/ubuntu/+source/chrpath">Ubuntu</a> and
 133 <a href="https://admin.fedoraproject.org/pkgdb/acls/name/chrpath">Fedora</a>
 134 packages for interesting patches (failed to find the source from
 135 OpenSUSE and Mandriva packages), and found quite a few nice fixes.
 136 These are the release notes:</p>
 137
 138 <p>New in 0.15 released 2013-11-24:</p>
 139
 140 <ul>
 141
 142   <li>Updated config.sub and config.guess from the GNU project to work
 143    with newer architectures.  Thanks to isha vishnoi for the heads
 144    up.</li>
 145
 146   <li>Updated README with current URLs.</li>
 147
 148   <li>Added byteswap fix found in Ubuntu, credited Jeremy Kerr and
 149    Matthias Klose.</li>
 150
 151   <li>Added missing help for -k|--keepgoing option, using patch by
 152    Petr Machata found in Fedora.</li>
 153
 154   <li>Rewrite removal of RPATH/RUNPATH to make sure the entry in
 155    .dynamic is a NULL terminated string.  Based on patch found in
 156    Fedora credited Axel Thimm and Christian Krause.</li>
 157
 158 </ul>
 159
 160 <p>You can
 161 <a href="https://alioth.debian.org/frs/?group_id=31052">download the
 162 new version 0.15 from alioth</a>.  Please let us know via the Alioth
 163 project if something is wrong with the new release.  The test suite
 164 did not discover any old errors, so if you find a new one, please also

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

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

 362 <a href="http://downloads.openwrt.org/snapshots/trunk/ar71xx/openwrt-ar71xx-generic-tl-mr3040-v2-squashfs-factory.bin">the
 363 recommended firmware image</a>
 364 (openwrt-ar71xx-generic-tl-mr3040-v2-squashfs-factory.bin) and
 365 uploaded it into the original web interface.  The flashing went fine,
 366 and the machine was available via telnet on the ethernet port.  After
 367 logging in and setting the root password, ssh was available and I
 368 could start to set it up as a batman-adv mesh node.</p>
 369
 370 <p>I started off by reading the instructions from
 371 <a href="http://wirelessafrica.meraka.org.za/wiki/index.php?title=Antoine's_Research">Wireless
 372 Africa</a>, which had quite a lot of useful information, but
 373 eventually I followed the recipe from the Open Mesh wiki for
 374 <a href="http://www.open-mesh.org/projects/batman-adv/wiki/Batman-adv-openwrt-config">using
 375 batman-adv on OpenWrt</a>.  A small snag was the fact that the
 376 <tt>opkg install kmod-batman-adv</tt> command did not work as it
 377 should.  The batman-adv kernel module would fail to load because its
 378 dependency crc16 was not already loaded.  I
 379 <a href="https://dev.openwrt.org/ticket/14452">reported the bug</a> to
 380 the openwrt project and hope it will be fixed soon.  But the problem
 381 only seem to affect initial testing of batman-adv, as configuration
 382 seem to work when booting from scratch.</p>
 383
 384 <p>The setup is done using files in /etc/config/.  I did not bridge
 385 the Ethernet and mesh interfaces this time, to be able to hook up the
 386 box on my local network and log into it for configuration updates.
 387 The following files were changed and look like this after modifying
 388 them:</p>

 491         <p>If one of the points of switching to a new init system in Debian is
 492 <a href="http://thomas.goirand.fr/blog/?p=147">to get rid of huge
 493 init.d scripts</a>, I doubt we need to switch away from sysvinit and
 494 init.d scripts at all.  Here is an example init.d script, ie a rewrite
 495 of /etc/init.d/rsyslog:</p>
 496
 497 <p><pre>
 498 #!/lib/init/init-d-script
 499 ### BEGIN INIT INFO
 500 # Provides:          rsyslog
 501 # Required-Start:    $remote_fs $time
 502 # Required-Stop:     umountnfs $time

 504 # Default-Start:     2 3 4 5
 505 # Default-Stop:      0 1 6
 506 # Short-Description: enhanced syslogd
 507 # Description:       Rsyslog is an enhanced multi-threaded syslogd.
 508 #                    It is quite compatible to stock sysklogd and can be
 509 #                    used as a drop-in replacement.

 515 <p>Pretty minimalistic to me... For the record, the original sysv-rc
 516 script was 137 lines, and the above is just 15 lines, most of it meta

 518

 672 <p>It is based on /etc/init.d/skeleton, and could be improved quite a
 673 lot.  I did not really polish the approach, so it might not always
 674 work out of the box, but you get the idea.  I did not try very hard to
 675 optimize it nor make it more robust either.</p>
 676
 677 <p>A better argument for switching init system in Debian than reducing
 678 the size of init scripts (which is a good thing to do anyway), is to
 679 get boot system that is able to handle the kernel events sensibly and
 680 robustly, and do not depend on the boot to run sequentially.  The boot
 681 and the kernel have not behaved sequentially in years.</p>

 708 2013-04-01, so I decided to wrap up a package based on the great work
 709 from Cajus Pollmeier and put it in a collab-maint maintained git
 710 repository to get a package I could use.  I would very much like
 711 others to help me maintain the package (or just take over, I do not
