  14                 <description>&lt;p&gt;For et halvt år siden
  15 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/SQL_database_med_anbud_publisert_p__Doffin.html&quot;&gt;satte
  16 jeg opp et system for å lage en database&lt;/a&gt; med informasjon om
  17 offentlige anbud fra &lt;a href=&quot;http://www.doffin.no/&quot;&gt;Doffin&lt;/a&gt; ved
  18 &lt;a href=&quot;https://scraperwiki.com/scrapers/norwegian-doffin/&quot;&gt;hjelp av
  19 Scraperwiki&lt;/a&gt;.  Nå er databasen så vidt jeg kan se komplett, med
  20 data helt tilbake til 2008.  Her er litt statistikk over

 107                 <pubDate>Sun, 10 Feb 2013 12:50:00 +0100</pubDate>
 108                 <description>&lt;p&gt;&lt;img align=&quot;left&quot; style=&quot;margin-right:25px;&quot; src=&quot;http://people.skolelinux.org/pere/blog/images/2013-02-10-morning-light.jpeg&quot;&gt;&lt;/p&gt;
 109
 110 &lt;p&gt;With kids in the house, one challenge is getting them to sleep
 111 during the night and wake up when it is morning.  I mean, when I
 112 believe it is morning, and not two hours earlier.  In our household we
 113 have decided that 07:00 is the turning point, but getting the kids to
 114 sleep until 07:00 is a small challenge every day.  They have adapted
 115 quite well, and rarely wake up at 05:00 any more, but some times wake
 116 up at times like 05:50, 06:15, 06:30 or 06:45, and it is hard to put
 117 the awake one to bed again without disturbing and waking the rest.
 118 And I understand perfectly well that they fail to sleep until 07:00
 119 some times, as there is no way for them to know if it is before or
 120 after the magic moment without coming and asking us parents.&lt;/p&gt;
 121
 122 &lt;p&gt;But yesterday I came up with a method to solve this problem.  It
 123 involve home automation.  A few years ago I bought a
 124 &lt;a href=&quot;http://www.telldus.se/products/tellstick&quot;&gt;Tellstick&lt;/a&gt; and RF
 125 switches at the local &lt;a href=&quot;http://www.clasohlson.com/&quot;&gt;Clas
 126 Ohlson&lt;/a&gt; shop, allowing me to control lights and other electrical
 127 gadgets using my Linux server.  When I moved from the old flat to a
 128 small house, I put away all this equipment as most of the lighting in
 129 the house was not using wall sockets and thus not easy to connect to
 130 the gadgets I had.  But recently I bought a
 131 &lt;a href=&quot;http://www.telldus.se/products/tellstick_net&quot;&gt;Tellstick
 132 Net&lt;/a&gt; to be able to read sensor input as well as control power
 133 sockets.  I want to control ovens in the basement to avoid the pipes
 134 to freeze, and monitor the humidity to detect flooding.  The default
 135 setup for Tellstick Net is to be controlled by the vendor web service,
 136 which to me is a security problem, but it is also possible to build
 137 ones own
 138 &lt;a href=&quot;http://developer.telldus.com/blog/2012/03/02/help-us-develop-local-access-using-tellstick-net-build-your-own-firmware&quot;&gt;firmware
 139 with local access&lt;/A&gt; instead of being controlled by a Swedish
 140 company, thanks to the release of the GPL licensed firmware source
 141 code.  I plan to get that running before I let it control anything
 142 important.  But while working on this, one idea to make it easier for
 143 the kids came to me yesterday.  We can set up a night light controlled
 144 by the computer, and turn it automatically on at 07:00.  The kids can
 145 then check the light in the morning to know if they are supposed to
 146 get up or not.  They joined me in setting everything up, and I
 147 repeated the concept several times before bed times to make sure they
 148 remembered to check the light before getting up in the morning.&lt;/p&gt;
 149
 150 &lt;p&gt;We tested it this morning, and all the kids stayed in bed until
 151 after 07:00, and every one of them commented on the fact that the
 152 &quot;morning light&quot; was turned on and signalled that the morning had
 153 arrived.  So this look like a success, and I am excited to see how
 154 this develops the next few days. :) I really hope this can allow us
 155 all to sleep a bit longer in the morning.&lt;/p&gt;
 156
 157 &lt;p&gt;A nice advantage of this setup is that we can remote control when
 158 to tell the kids to get up.  We do not have to wait until 07:00, and
 159 can also delay it if we want to.&lt;/p&gt;

 168                 <description>&lt;p&gt;Nytt stortingsvalg er på trappene, og folket får igjen mulighet til
 169 å påvirke sammensetningen i vår lovgivende forsamling.  Da er det
 170 relevant å vite hvilke representanter og partier som har støttet
 171 innføringen av brev- og besøkskontroll av hele den norske
 172 befolkningen, det vil si datalagringsdirektivet.&lt;/p&gt;
 173
 174 &lt;p&gt;Hvis du vil vite hva hver enkelt stortingsrepresentant har stemt i
 175 stortingsvoteringene om datalagringsdirektivet, så har nettstedet til
 176 &lt;a href=&quot;http://www.holderdeord.no/&quot;&gt;Holder De Ord&lt;/a&gt; den (så vidt jeg
 177 vet) eneste komplette oversikten på sin temaside om
 178 &lt;a href=&quot;http://beta.holderdeord.no/issues/innfore-datalagringsdirektivet&quot;&gt;innføringen
 179 av datalagringsdirektivet&lt;/a&gt;.  Den har detaljene fra de 11 relevante
 180 forslagene som har vært fremmet så lagt.  De har vært votert over
 181 2011-04-04, 2011-04-11, 2012-06-11, 2012-10-05 og 2012-12-06.&lt;/p&gt;
 182
 183 &lt;p&gt;Hvis du lurer på hva som er problemet med datalagringsdirektivet,
 184 anbefaler jeg å lese &lt;a href=&quot;http://www.uhuru.biz/?cat=84&quot;&gt;artiklene
 185 fra Jon Wessel-Aas&lt;/a&gt; om temaet, samt informasjon fra foreningen
 186 &lt;a href=&quot;http://www.digitaltpersonvern.no/&quot;&gt;Digitalt
 187 Personvern&lt;/a&gt;.&lt;/p&gt;

 196                 <description>&lt;p&gt;Jeg ser med gru at Arbeiderpartiet, Høyre og Fremskrittspartiet
 197 &lt;a href=&quot;http://www.aftenposten.no/nyheter/iriks/Positive-til-mer-smuglerovervaking-7110348.html&quot;&gt;applauderer
 198 tollvesenets forslag&lt;/a&gt; om å øke overvåkningen i Norge nok et hakk.
 199 Det er ikke så rart, da de som uttaler seg jo også har støttet
 200 innføringen av datalagringsdirektivet eller i hvert fall ikke veldig
 201 aktivt har motarbeidet det.  Innføringen av datalagringsdirektivet er
 202 en lovendring som innebærer brev og besøkskontroll for hele
 203 befolkningen.&lt;/p&gt;
 204
 205 &lt;p&gt;&lt;a href=&quot;http://www.stortinget.no/no/Saker-og-publikasjoner/Saker/Sak/?p=48717&quot;&gt;Datalagringsdirektivet&lt;/a&gt;
 206 har vært oppe til votering i stortinget tre ganger så langt.  Det ble
 207 &lt;a href=&quot;http://svartelisten.org/&quot;&gt;vedtatt første gang 2011-04-04&lt;/a&gt;
 208 og
 209 &lt;a href=&quot;https://github.com/holderdeord/hdo-folketingparser/blob/master/data/votering-2011-04-11.xml&quot;&gt;andre
 210 gang 2011-04-11&lt;/a&gt; (lovendringer voteres to ganger), og forslag om å
 211 stoppe loven ble
 212 &lt;a href=&quot;http://www.stortinget.no/no/Saker-og-publikasjoner/Saker/Sak/Voteringsoversikt/?p=53844&amp;dnid=1&quot;&gt;nedstemt
 213 2012-12-06&lt;/a&gt; (se også
 214 &lt;a href=&quot;http://beta.holderdeord.no/issues/innfore-datalagringsdirektivet&quot;&gt;oversikt fra Holder De
 215 Ord&lt;/a&gt;).&lt;/p&gt;
 216
 217 &lt;p&gt;Jan Bøhler i Arbeiderpartiet stemte for å innføre
 218 datalagringsdirektivet i lovverket i første votering, var ikke
 219 tilstede i andre votering og støttet loven i tredje votering.  André
 220 Oktay Dahl i Høyre var ikke til stede i første og andre votering men
 221 støttet loven i tredje votering.  Ulf Leirstein i Fremskrittspartiet
 222 stemte mot loven i første votering men var ikke til stede i andre og
 223 tredje votering.&lt;/p&gt;
 224
 225 &lt;p&gt;Hvis du lurer på hva som er problemet med datalagringsdirektivet,
 226 anbefaler jeg å lese &lt;a href=&quot;http://www.uhuru.biz/?cat=84&quot;&gt;artiklene
 227 fra Jon Wessel-Aas&lt;/a&gt; om temaet, samt informasjon fra foreningen

 241                 <pubDate>Sat, 2 Feb 2013 09:00:00 +0100</pubDate>
 242                 <description>&lt;p&gt;My
 243 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/How_to_backport_bitcoin_qt_version_0_7_2_2_to_Debian_Squeeze.html&quot;&gt;last
 244 bitcoin related blog post&lt;/a&gt; mentioned that the new
 245 &lt;a href=&quot;http://packages.qa.debian.org/bitcoin&quot;&gt;bitcoin package&lt;/a&gt; for
 246 Debian was waiting in NEW.  It was accepted by the Debian ftp-masters
 247 2013-01-19, and have been available in unstable since then.  It was
 248 automatically copied to Ubuntu, and is available in their Raring
 249 version too.&lt;/p&gt;
 250
 251 &lt;p&gt;But there is a strange problem with the build that block this new
 252 version from being available on the i386 and kfreebsd-i386
 253 architectures.  For some strange reason, the autobuilders in Debian
 254 for these architectures fail to run the test suite on these
 255 architectures (&lt;a href=&quot;http://bugs.debian.org/672524&quot;&gt;BTS #672524&lt;/a&gt;).
 256 We are so far unable to reproduce it when building it manually, and
 257 no-one have been able to propose a fix.  If you got an idea what is
 258 failing, please let us know via the BTS.&lt;/p&gt;
 259
 260 &lt;p&gt;One feature that is annoying me with of the bitcoin client, because
 261 I often run low on disk space, is the fact that the client will exit
 262 if it run short on space (&lt;a href=&quot;http://bugs.debian.org/696715&quot;&gt;BTS
 263 #696715&lt;/a&gt;).  So make sure you have enough disk space when you run
 264 it. :)&lt;/p&gt;
 265
 266 &lt;p&gt;As usual, if you use bitcoin and want to show your support of my
 267 activities, please send Bitcoin donations to my address
 268 &lt;b&gt;&lt;a href=&quot;bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&amp;label=PetterReinholdtsenBlog&quot;&gt;15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&lt;/a&gt;&lt;/b&gt;.&lt;/p&gt;

 276                 <pubDate>Tue, 22 Jan 2013 22:00:00 +0100</pubDate>
 277                 <description>&lt;p&gt;Yesterday, I
 278 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/First_prototype_ready_making_hardware_easier_to_use_in_Debian.html&quot;&gt;asked
 279 for testers&lt;/a&gt; for my prototype for making Debian better at handling
 280 pluggable hardware devices, which I
 281 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html&quot;&gt;set
 282 out to create&lt;/a&gt; earlier this month.  Several valuable testers showed
 283 up, and caused me to really want to to open up the development to more
 284 people.  But before I did this, I want to come up with a sensible name
 285 for this project.  Today I finally decided on a new name, and I have
 286 renamed the project from hw-support-handler to this new name.  In the
 287 process, I moved the source to git and made it available as a
 288 &lt;a href=&quot;http://anonscm.debian.org/gitweb/?p=collab-maint/isenkram.git&quot;&gt;collab-maint&lt;/a&gt;
 289 repository in Debian.  The new name?  It is &lt;strong&gt;Isenkram&lt;/strong&gt;.
 290 To fetch and build the latest version of the source, use&lt;/p&gt;
 291
 292 &lt;pre&gt;
 293 git clone http://anonscm.debian.org/git/collab-maint/isenkram.git
 294 cd isenkram &amp;&amp; git-buildpackage -us -uc
 295 &lt;/pre&gt;
 296
 297 &lt;p&gt;I have not yet adjusted all files to use the new name yet.  If you
 298 want to hack on the source or improve the package, please go ahead.
 299 But please talk to me first on IRC or via email before you do major
 300 changes, to make sure we do not step on each others toes. :)&lt;/p&gt;
 301
 302 &lt;p&gt;If you wonder what &#39;isenkram&#39; is, it is a Norwegian word for iron
 303 stuff, typically meaning tools, nails, screws, etc.  Typical hardware
 304 stuff, in other words.  I&#39;ve been told it is the Norwegian variant of
 305 the German word eisenkram, for those that are familiar with that
 306 word.&lt;/p&gt;
 307
 308 &lt;p&gt;&lt;strong&gt;Update 2013-01-26&lt;/strong&gt;: Added -us -us to build
 309 instructions, to avoid confusing people with an error from the signing
 310 process.&lt;/p&gt;
 311
 312 &lt;p&gt;&lt;strong&gt;Update 2013-01-27&lt;/strong&gt;: Switch to HTTP URL for the git
 313 clone argument to avoid the need for authentication.&lt;/p&gt;

 319                 <link>http://people.skolelinux.org/pere/blog/First_prototype_ready_making_hardware_easier_to_use_in_Debian.html</link>
 320                 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/First_prototype_ready_making_hardware_easier_to_use_in_Debian.html</guid>
 321                 <pubDate>Mon, 21 Jan 2013 12:00:00 +0100</pubDate>
 322                 <description>&lt;p&gt;Early this month I set out to try to
 323 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html&quot;&gt;improve
 324 the Debian support for pluggable hardware devices&lt;/a&gt;.  Now my
 325 prototype is working, and it is ready for a larger audience.  To test
 326 it, fetch the
 327 &lt;a href=&quot;http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/&quot;&gt;source
 328 from the Debian Edu subversion repository&lt;/a&gt;, build and install the
 329 package.  You might have to log out and in again activate the
 330 autostart script.&lt;/p&gt;
 331
 332 &lt;p&gt;The design is simple:&lt;/p&gt;
 333
 334 &lt;ul&gt;
 335
 336 &lt;li&gt;Add desktop entry in /usr/share/autostart/ causing a program
 337 hw-support-handlerd to start when the user log in.&lt;/li&gt;
 338
 339 &lt;li&gt;This program listen for kernel events about new hardware (directly
 340 from the kernel like udev does), not using HAL dbus events as I
 341 initially did.&lt;/li&gt;
 342
 343 &lt;li&gt;When new hardware is inserted, look up the hardware modalias in
 344 the APT database, a database
 345 &lt;a href=&quot;http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=markup&quot;&gt;available
 346 via HTTP&lt;/a&gt; and a database available as part of the package.&lt;/li&gt;
 347
 348 &lt;li&gt;If a package is mapped to the hardware in question, the package
 349 isn&#39;t installed yet and this is the first time the hardware was
 350 plugged in, show a desktop notification suggesting to install the
 351 package or packages.&lt;/li&gt;
 352
 353 &lt;li&gt;If the user click on the &#39;install package now&#39; button, ask
 354 aptdaemon via the PackageKit API to install the requrired package.&lt;/li&gt;
 355
 356 &lt;li&gt;aptdaemon ask for root password or sudo password, and install the
 357 package while showing progress information in a window.&lt;/li&gt;
 358
 359 &lt;/ul&gt;
 360
 361 &lt;p&gt;I still need to come up with a better name for the system.  Here
 362 are some screen shots showing the prototype in action.  First the
 363 notification, then the password request, and finally the request to
 364 approve all the dependencies.  Sorry for the Norwegian Bokmål GUI.&lt;/p&gt;
 365
 366 &lt;p&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2013-01-21-hw-support-1-notification.png&quot;&gt;
 367 &lt;br&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2013-01-21-hw-support-2-password.png&quot;&gt;
 368 &lt;br&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2013-01-21-hw-support-3-dependencies.png&quot;&gt;
 369 &lt;br&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2013-01-21-hw-support-4-installing.png&quot;&gt;
 370 &lt;br&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2013-01-21-hw-support-5-installing-details.png&quot; width=&quot;70%&quot;&gt;&lt;/p&gt;
 371
 372 &lt;p&gt;The prototype still need to be improved with longer timeouts, but
 373 is already useful.  The database of hardware to package mappings also
 374 need more work.  It is currently compatible with the Ubuntu way of
 375 storing such information in the package control file, but could be
 376 changed to use other formats instead or in addition to the current
 377 method.  I&#39;ve dropped the use of discover for this mapping, as the
 378 modalias approach is more flexible and easier to use on Linux as long
 379 as the Linux kernel expose its modalias strings directly.&lt;/p&gt;
 380
 381 &lt;p&gt;&lt;strong&gt;Update 2013-01-21 16:50&lt;/strong&gt;: Due to popular demand,
 382 here is the command required to check out and build the source: Use
 383 &#39;&lt;tt&gt;svn checkout
 384 svn://svn.debian.org/debian-edu/trunk/src/hw-support-handler/; cd
 385 hw-support-handler; debuild&lt;/tt&gt;&#39;.  If you lack debuild, install the
 386 devscripts package.&lt;/p&gt;
 387
 388 &lt;p&gt;&lt;strong&gt;Update 2013-01-23 12:00&lt;/strong&gt;: The project is now
 389 renamed to Isenkram and the source moved from the Debian Edu
 390 subversion repository to a Debian collab-maint git repository.  See
 391 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Welcome_to_the_world__Isenkram_.html&quot;&gt;build
 392 instructions&lt;/a&gt; for details.&lt;/p&gt;

 401                 <description>&lt;p&gt;This Christmas my trusty old laptop died.  It died quietly and
 402 suddenly in bed.  With a quiet whimper, it went completely quiet and
 403 black.  The power button was no longer able to turn it on.  It was a
 404 IBM Thinkpad X41, and the best laptop I ever had.  Better than both
 405 Thinkpads X30, X31, X40, X60, X61 and X61S.  Far better than the
 406 Compaq I had before that.  Now I need to find a replacement.  To keep
 407 going during Christmas, I moved the one year old SSD disk to my old
 408 X40 where it fitted (only one I had left that could use it), but it is
 409 not a durable solution.
 410
 411 &lt;p&gt;My laptop needs are fairly modest.  This is my wishlist from when I
 412 got a new one more than 10 years ago.  It still holds true.:)&lt;/p&gt;
 413
 414 &lt;ul&gt;
 415
 416 &lt;li&gt;Lightweight (around 1 kg) and small volume (preferably smaller
 417   than A4).&lt;/li&gt;
 418 &lt;li&gt;Robust, it will be in my backpack every day.&lt;/li&gt;
 419 &lt;li&gt;Three button mouse and a mouse pin instead of touch pad.&lt;/li&gt;
 420 &lt;li&gt;Long battery life time.  Preferable a week.&lt;/li&gt;
 421 &lt;li&gt;Internal WIFI network card.&lt;/li&gt;
 422 &lt;li&gt;Internal Twisted Pair network card.&lt;/li&gt;
 423 &lt;li&gt;Some USB slots (2-3 is plenty)&lt;/li&gt;
 424 &lt;li&gt;Good keyboard - similar to the Thinkpad.&lt;/li&gt;
 425 &lt;li&gt;Video resolution at least 1024x768, with size around 12&quot; (A4 paper
 426 size).&lt;/li&gt;
 427 &lt;li&gt;Hardware supported by Debian Stable, ie the default kernel and
 428   X.org packages.&lt;/li&gt;
 429 &lt;li&gt;Quiet, preferably fan free (or at least not using the fan most of
 430   the time).
 431
 432 &lt;/ul&gt;
 433
 434 &lt;p&gt;You will notice that there are no RAM and CPU requirements in the
 435 list.  The reason is simply that the specifications on laptops the
 436 last 10-15 years have been sufficient for my needs, and I have to look
 437 at other features to choose my laptop.  But are there still made as
 438 robust laptops as my X41?  The Thinkpad X60/X61 proved to be less
 439 robust, and Thinkpads seem to be heading in the wrong direction since
 440 Lenovo took over.  But I&#39;ve been told that X220 and X1 Carbon might
 441 still be useful.&lt;/p&gt;
 442
 443 &lt;p&gt;Perhaps I should rethink my needs, and look for a pad with an
 444 external keyboard?  I&#39;ll have to check the
 445 &lt;a href=&quot;http://www.linux-laptop.net/&quot;&gt;Linux Laptops site&lt;/a&gt; for
 446 well-supported laptops, or perhaps just buy one preinstalled from one
 447 of the vendors listed on the &lt;a href=&quot;http://linuxpreloaded.com/&quot;&gt;Linux
 448 Pre-loaded site&lt;/a&gt;.&lt;/p&gt;

 456                 <pubDate>Fri, 18 Jan 2013 10:40:00 +0100</pubDate>
 457                 <description>&lt;p&gt;Some times I try to figure out which Iceweasel browser plugin to
 458 install to get support for a given MIME type.  Thanks to
 459 &lt;a href=&quot;https://wiki.ubuntu.com/MozillaTeam/Plugins&quot;&gt;specifications
 460 done by Ubuntu&lt;/a&gt; and Mozilla, it is possible to do this in Debian.
 461 Unfortunately, not very many packages provide the needed meta
 462 information, Anyway, here is a small script to look up all browser
 463 plugin packages announcing ther MIME support using this specification:&lt;/p&gt;
 464
 465 &lt;pre&gt;
 466 #!/usr/bin/python
 467 import sys
 468 import apt
 469 def pkgs_handling_mimetype(mimetype):
 470     cache = apt.Cache()
 471     cache.open(None)
 472     thepkgs = []
 473     for pkg in cache:
 474         version = pkg.candidate
 475         if version is None:
 476             version = pkg.installed
 477         if version is None:
 478             continue
 479         record = version.record
 480         if not record.has_key(&#39;Npp-MimeType&#39;):
 481             continue
 482         mime_types = record[&#39;Npp-MimeType&#39;].split(&#39;,&#39;)
 483         for t in mime_types:
 484             t = t.rstrip().strip()
 485             if t == mimetype:
 486                 thepkgs.append(pkg.name)
 487     return thepkgs
 488 mimetype = &quot;audio/ogg&quot;
 489 if 1 &lt; len(sys.argv):
 490     mimetype = sys.argv[1]
 491 print &quot;Browser plugin packages supporting %s:&quot; % mimetype
 492 for pkg in pkgs_handling_mimetype(mimetype):
 493     print &quot;  %s&quot; %pkg
 494 &lt;/pre&gt;
 495
 496 &lt;p&gt;It can be used like this to look up a given MIME type:&lt;/p&gt;
 497
 498 &lt;pre&gt;
 499 % ./apt-find-browserplug-for-mimetype
 500 Browser plugin packages supporting audio/ogg:
 501   gecko-mediaplayer
 502 % ./apt-find-browserplug-for-mimetype application/x-shockwave-flash
 503 Browser plugin packages supporting application/x-shockwave-flash:
 504   browser-plugin-gnash
 505 %
 506 &lt;/pre&gt;
 507
 508 &lt;p&gt;In Ubuntu this mechanism is combined with support in the browser
 509 itself to query for plugins and propose to install the needed
 510 packages.  It would be great if Debian supported such feature too.  Is
 511 anyone working on adding it?&lt;/p&gt;
 512
 513 &lt;p&gt;&lt;strong&gt;Update 2013-01-18 14:20&lt;/strong&gt;: The Debian BTS
 514 request for icweasel support for this feature is
 515 &lt;a href=&quot;http://bugs.debian.org/484010&quot;&gt;#484010&lt;/a&gt; from 2008 (and
 516 &lt;a href=&quot;http://bugs.debian.org/698426&quot;&gt;#698426&lt;/a&gt; from today).  Lack
 517 of manpower and wish for a different design is the reason thus feature
 518 is not yet in iceweasel from Debian.&lt;/p&gt;

 527                 <description>&lt;p&gt;The &lt;a href=&quot;http://wiki.debian.org/AppStreamDebianProposal&quot;&gt;DEP-11
 528 proposal to add AppStream information to the Debian archive&lt;/a&gt;, is a
 529 proposal to make it possible for a Desktop application to propose to
 530 the user some package to install to gain support for a given MIME
 531 type, font, library etc. that is currently missing.  With such
 532 mechanism in place, it would be possible for the desktop to
 533 automatically propose and install leocad if some LDraw file is
 534 downloaded by the browser.&lt;/p&gt;
 535
 536 &lt;p&gt;To get some idea about the current content of the archive, I decided
 537 to write a simple program to extract all .desktop files from the
 538 Debian archive and look up the claimed MIME support there.  The result
 539 can be found on the
 540 &lt;a href=&quot;http://ftp.skolelinux.org/pub/AppStreamTest&quot;&gt;Skolelinux FTP
 541 site&lt;/a&gt;.  Using the collected information, it become possible to
 542 answer the question in the title.  Here are the 20 most supported MIME
 543 types in Debian stable (Squeeze), testing (Wheezy) and unstable (Sid).
 544 The complete list is available from the link above.&lt;/p&gt;

 627 &lt;p&gt;I am told that PackageKit can provide an API to access the kind of
 628 information mentioned in DEP-11.  I have not yet had time to look at
 629 it, but hope the PackageKit people in Debian are on top of these
 630 issues.&lt;/p&gt;
