  24       <div class="date"> 9th January 2013</div>
  25       <div class="body"><p>One thing that annoys me with Debian and Linux distributions in
  26 general, is that there is a great package management system with the
  27 ability to automatically install software packages by downloading them
  28 from the distribution mirrors, but no way to get it to automatically
  29 install the packages I need to use the hardware I plug into my
  30 machine.  Even if the package to use it is easily available from the
  31 Linux distribution.  When I plug in a LEGO Mindstorms NXT, it could
  32 suggest to automatically install the python-nxt, nbc and t2n packages
  33 I need to talk to it.  When I plug in a Yubikey, it could propose the
  34 yubikey-personalization package.  The information required to do this
  35 is available, but no-one have pulled all the pieces together.</p>
  36
  37 <p>Many years ago, I proposed to
  38 <a href="http://lists.debian.org/debian-devel/2010/05/msg01206.html">use
  39 the discover subsystem to implement this</a>.  The idea is fairly
  40 simple:
  41
  42 <ul>
  43
  44 <li>Add a desktop entry in /usr/share/autostart/ pointing to a program
  45   starting when a user log in.</li>
  46
  47 <li>Set this program up to listen for kernel events emitted when new
  48   hardware is inserted into the computer.</li>
  49
  50 <li>When new hardware is inserted, look up the hardware ID in a
  51   database mapping to packages, and take note of any non-installed
  52   packages.</li>
  53
  54 <li>Show a message to the user proposing to install the discovered
  55   package, and make it easy to install it.</li>
  56
  57 </ul>
  58
  59 <p>I am not sure what the best way to implement this is, but my
  60 initial idea was to use dbus events to discover new hardware, the
  61 discover database to find packages and
  62 <a href="http://www.packagekit.org/">PackageKit</a> to install
  63 packages.</p>
  64
  65 <p>Yesterday, I found time to try to implement this idea, and the
  66 draft package is now checked into
  67 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">the
  68 Debian Edu subversion repository</a>.  In the process, I updated the
  69 <a href="http://packages.qa.debian.org/d/discover-data.html">discover-data</a>
  70 package to map the USB ids of LEGO Mindstorms and Yubikey devices to
  71 the relevant packages in Debian, and uploaded a new version
  72 2.2013.01.09 to unstable.  I also discovered that the current
  73 <a href="http://packages.qa.debian.org/d/discover-data.html">discover</a>
  74 package in Debian no longer discovered any USB devices, because
  75 /proc/bus/usb/devices is no longer present.  I ported it to use
  76 libusb as a fall back option to get it working.  The fixed package
  77 version 2.1.2-6 is now in experimental (didn't upload it to unstable
  78 because of the freeze).</p>
  79
  80 <p>With this prototype in place, I can insert my Yubikey, and get this
  81 desktop notification to show up (only once, the first time it is
  82 inserted):</p>
  83
  84 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2013-01-09-hw-autoinstall.png"></p>
  85
  86 <p>For this prototype to be really useful, some way to automatically
  87 install the proposed packages by pressing the "Please install
  88 program(s)" button should to be implemented.</p>
  89
  90 <p>If this idea seem useful to you, and you want to help make it
  91 happen, please help me update the discover-data database with mappings
  92 from hardware to Debian packages.  Check if 'discover-pkginstall -l'
  93 list the package you would like to have installed when a given
  94 hardware device is inserted into your computer, and report bugs using
  95 reportbug if it isn't.  Or, if you know of a better way to provide
  96 such mapping, please let me know.</p>
  97
  98 <p>This prototype need more work, and there are several questions that
  99 should be considered before it is ready for production use.  Is dbus
 100 the correct way to detect new hardware?  At the moment I look for HAL
 101 dbus events on the system bus, because that is the events I could see
 102 on my Debian Squeeze KDE desktop.  Are there better events to use?
 103 How should the user be notified?  Is the desktop notification
 104 mechanism the best option, or should the background daemon raise a
 105 popup instead?  How should packages be installed?  When should they
 106 not be installed?</p>
 107
 108 <p>If you want to help getting such feature implemented in Debian,
 109 please send me an email. :)</p>

 257       <div class="body"><p>I was happy to discover a few days ago that the
 258 <a href="http://www.skolelinux.org/">Skolelinux / Debian Edu</a>
 259 project also this year received a Christmas present from Another
 260 Agency in Trondheim.  NOK 1000,- showed up on our donation account
 261 December 24th.  I want to express our thanks for this very welcome
 262 present.  As the Debian Edu / Skolelinux project is very short on
 263 funding these days, and thus lack the money to do regular developer
 264 gatherings, this donation was most welcome.  One developer gathering
 265 cost around NOK 15&nbsp;000,-, so we need quite a lot more to keep the
 266 development pace we want.  Thus, I hope their example this year is
 267 followed by many others. :)</p>

 269 <p>The public list of donors can be found on
 270 <a href="http://www.linuxiskolen.no/slxdebianlabs/donations.html">the

 290 <p><a href="http://www.bitcoin.org/">Bitcoin</a>, the digital
 291 decentralised "currency" that allow people to transfer bitcoins
 292 between each other with minimal overhead, is a very interesting
 293 experiment.  And as I wrote a few days ago, the bitcoin situation in
 294 <a href="http://www.debian.org/">Debian</a> is about to improve a bit.
 295 The <a href="http://packages.qa.debian.org/bitcoin">new debian source
 296 package</a> (version 0.7.2-2) was uploaded yesterday, and is waiting
 297 in <a href="http://ftp-master.debian.org/new.html">the NEW queue</A>
 298 for one of the ftpmasters to approve the new bitcoin-qt package
 299 name.</p>
 300
 301 <p>And thanks to the great work of Jonas and the rest of the bitcoin
 302 team in Debian, you can easily test the package in Debian Squeeze
 303 using the following steps to get a set of working packages:</p>
 304
 305 <blockquote><pre>
 306 git clone git://git.debian.org/git/collab-maint/bitcoin
 307 cd bitcoin
 308 DEB_MAINTAINER_MODE=1 DEB_BUILD_OPTIONS=noupnp fakeroot debian/rules clean
 309 DEB_BUILD_OPTIONS=noupnp git-buildpackage --git-ignore-new
 310 </pre></blockquote>
 311
 312 <p>You might have to install some build dependencies as well.  The
 313 list of commands should give you two packages, bitcoind and
 314 bitcoin-qt, ready for use in a Squeeze environment.  Note that the
 315 client will download the complete set of bitcoin "blocks", which need
 316 around 5.6 GiB of data on my machine at the moment.  Make sure your
 317 ~/.bitcoin/ directory have lots of spare room if you want to download
 318 all the blocks.  The client will warn if the disk is getting full, so
 319 there is not really a problem if you got too little room, but you will
 320 not be able to get all the features out of the client.</p>
 321
 322 <p>As usual, if you use bitcoin and want to show your support of my
 323 activities, please send Bitcoin donations to my address

 338       <div class="date">21st December 2012</div>
 339       <div class="body"><p>It has been a while since I wrote about
 340 <a href="http://www.bitcoin.org/">bitcoin</a>, the decentralised
 341 peer-to-peer based crypto-currency, and the reason is simply that I
 342 have been busy elsewhere.  But two days ago, I started looking at the
 343 state of <a href="http://packages.qa.debian.org/bitcoin">bitcoin in
 344 Debian</a> again to try to recover my old bitcoin wallet.  The package
 345 is now maintained by a
 346 <a href="https://alioth.debian.org/projects/pkg-bitcoin/">team of
 347 people</a>, and the grunt work had already been done by this team.  We
 348 owe a huge thank you to all these team members. :)
 349 But I was sad to discover that the bitcoin client is missing in
 350 Wheezy.  It is only available in Sid (and an outdated client from
 351 backports).  The client had several RC bugs registered in BTS blocking
 352 it from entering testing.  To try to help the team and improve the
 353 situation, I spent some time providing patches and triaging the bug
 354 reports.  I also had a look at the bitcoin package available from Matt
 355 Corallo in a
 356 <a href="https://launchpad.net/~bitcoin/+archive/bitcoin">PPA for
 357 Ubuntu</a>, and moved the useful pieces from that version into the
 358 Debian package.</p>
 359
 360 <p>After checking with the main package maintainer Jonas Smedegaard on
 361 IRC, I pushed several patches into the collab-maint git repository to
 362 improve the package.  It now contains fixes for the RC issues (not from
 363 me, but fixed by Scott Howard), build rules for a Qt GUI client
 364 package, konqueror support for the bitcoin: URI and bash completion
 365 setup.  As I work on Debian Squeeze, I also created
 366 <a href="http://lists.alioth.debian.org/pipermail/pkg-bitcoin-devel/Week-of-Mon-20121217/000041.html">a
 367 patch to backport</a> the latest version.  Jonas is going to look at
 368 it and try to integrate it into the git repository before uploading a
 369 new version to unstable.
 370
 371 <p>I would very much like bitcoin to succeed, to get rid of the
 372 centralized control currently exercised in the monetary system.  I
 373 find it completely unacceptable that the USA government is collecting
 374 transaction data for almost all international money transfers (most are done in USD and transaction logs shipped to the spooks), and
 375 that the major credit card companies can block legal money
 376 transactions to Wikileaks.  But for bitcoin to succeed, more people
 377 need to use bitcoins, and more people need to accept bitcoins when
 378 they sell products and services.  Improving the bitcoin support in
 379 Debian is a small step in the right direction, but not enough.
 380 Unfortunately the user experience when browsing the web and wanting to
 381 pay with bitcoin is still not very good.  The bitcoin: URI is a step
 382 in the right direction, but need to work in most or every browser in
 383 use.  Also the bitcoin-qt client is too heavy to fire up to do a

 388 <a href="http://people.skolelinux.org/pere/blog/Now_accepting_bitcoins___anonymous_and_distributed_p2p_crypto_money.html">experiment
 389 with bitcoins</a> showed that at least some of my readers use bitcoin.
 390 I received 20.15 BTC so far on the address I provided in my blog two
 391 years ago, as can be

 393 on the blockexplorer service</a>.  Thank you everyone for your
 394 donation.  The blockexplorer service demonstrates quite well that
 395 bitcoin is not quite anonymous and untracked. :) I wonder if the
 396 number of users have gone up since then.  If you use bitcoin and want
 397 to show your support of my activity, please send Bitcoin donations to
 398 the same address as last time,

 413       <div class="date">19th December 2012</div>
 414       <div class="body"><p>Jeg ble overrasket over å se at Piratpartiet i
 415 <a href="http://www.aftenposten.no/kultur/Piratpartiet-stiller-til-Stortingsvalget-7073298.html">Aftenposten</a>
 416 er referert på følgende:</p>
 417
 418 <blockquote>
 419 Når det gjelder retten til opphavsrett for kulturproduktene, mener
 420 Piratpartiet av levetid + 14 år er tilfredsstillende.
 421 </blockquote>
 422
 423 <p>Det betyr en vernetid langt ut over det kommersielle livet til de
 424 aller fleste opphavsrettsbeskyttede verker, og er i strid med slik i
 425 hvert fall jeg har tolket punkt 5 i
 426 <a href="http://people.opera.com/howcome/2012/piratpartiet/kjerneprogram.html">kjerneprogrammet
 427 til Piratpartiet</a>:</p>
 428
 429 <blockquote>
 430 <p><strong>5: Åndsverk og patenter: tilbake til start</strong></p>
 431
 432 <table border="1">
 433 <tr><th>forslag:</th><td>14 års opphavsrett og ingen
 434 programvarepatenter</td></tr>
 435
 436 <tr><th>grunn:</th><td>Den første loven om opphavsrett spesifiserte 14
 437 års vernetid. Senere har mediabransjens lobbyister stadig presset
 438 loven mot lengre vern, nå er det 70 år etter forfatters død. Dette
 439 gjør at mange verk glemmes og går tapt, noe som er skadelig for norsk
 440 språk og kultur. Vi til tilbake til start: 14 års
 441 vernetid. Patentloven sier klart at dataprogrammer ikke kan
 442 patenteres. Likevel klarer patentadvokater å lure gjennom
 443 programvarepatenter. Slike patenter gjør dingsene våre dyrere og kan i
 444 enkelte tilfelle stoppe dem helt.</th></tr>
 445 </table>
 446 </blockquote>
 447
 448 <p>Den opprinnelige opphavsretten var på 14 år totalt, ikke 14 år
 449 etter opphavspersonens død.  Jeg tenkte først dette kanskje var
 450 feilsitering fra Aftenposten, men jeg finner samme påstand i en <a
 451 href="http://piratpartietnorge.org/om-gramo-og-piratpolitikken/">bloggpost
 452 fra Geir Aaslid</a> på Piratpartietes offisielle nettsider.  Der
 453 skriver han følgende:</p>
 454
 455 <blockquote>
 456 Hva vi gjør med opphavsretten er mer komplisert fordi den omfavner så
 457 mange bransjer, med ulike behov. Enhver reform er en forbedring men
 458 det er nærliggende å anta at en opphavsrett på levetid + 14 år er
 459 fullt ut tilfredstillende for musikk, film, litteratur og spill.
 460 </blockquote>
 461
 462 <p>Det virker dermed på meg som om Piratpartiet allerede har gjort
 463 retrett fra sin beundringsverdige holdning om at det holdt med 14 års
 464 total vernetid, til sin nye som tar utgangspunkt i levetiden til
 465 opphavspersonen.  Jeg håper det baserer seg på en misforståelse hos
 466 piratlederen som blir korrigert tilbake til 14 års total vernetid før
 467 partiet stiller til valg.</p>
 468
 469 <p>Hvis du lurer på hvilke problemer lang vernetid bringer med seg,
 470 anbefaler jeg å lese boken <a href="http://free-culture.cc/">Free
 471 Culture</a> av Lawrence Lessig.  Jeg og en liten gruppe andre er igang
 472 med å
 473 <a href="https://github.com/petterreinholdtsen/free-culture-lessig">oversette
 474 boken til bokmål</a> og tar gjerne imot hjelp med oversettelse og
 475 korrekturlesing.</p>
 476
 477 <p><strong>Oppdatering 2012-12-20</strong>: Oppdaget at
 478 <a href="http://piratpartietnorge.org/om-gramo-og-piratpolitikken/">bloggposten
 479 til Geir Aaslid</a> er endret siden i går, og nå inneholder følgende
 480 avsnitt i stedet for det jeg siterte over:</p>
 481
 482 <blockquote>
 483 Hva vi gjør med opphavsretten er mer komplisert fordi den omfavner så
 484 mange bransjer, med ulike behov. Enhver reform er en forbedring men
 485 det er nærliggende å anta at en opphavsrett lik levetiden, evt + 14 år
 486 er fullt ut tilfredstillende for mange skapere av musikk, film,
 487 litteratur og spill. Det er for det meste de store forlagene som er
 488 imot enhver reform.
 489 </blockquote>
 490
 491 <p>I tillegg har det dukket opp en setning nederst "Dette dokumentet
 492 er et utkast til svar på et angrep på Piratpartiet fra Gramo. Det
 493 endrer seg derfor over tid og den endelige versjonen er det som blir
 494 publisert på Hardware.no", som tyder på at originalformuleringen ikke
 495 var veloverveid og sitatet i Aftenposten kanskje var basert på en
 496 misforståelse.</p>

 510       <div class="date">18th December 2012</div>
 511       <div class="body"><p>A few days ago I came across
 512 <a href="http://joeyh.name/blog/entry/hledger/">a blog post from Joey
 513 Hess</a> describing <a href="http://ledger-cli.org/">ledger</a> and
 514 hledger, a text based system for double-entry accounting.  I found it
 515 interesting, as I am involved with several organizations where
 516 accounting is an issue, and I have not really become too friendly with
 517 the different web based systems we use.  I find it hard to find what I
 518 look for in the menus and even harder try to get sensible data out of
 519 the systems.  Ledger seem different.  The accounting data is kept in
 520 text files that can be stored in a version control system, and there
 521
 522 are at least <a href="https://github.com/ledger/ledger/wiki/Ports">five
 523 different implementations</a> able to read the format.  An example
 524 entry look like this, and is simple enough that it will be trivial to
 525 generate entries based on CVS files fetched from the bank:</p>
 526
 527 <blockquote><pre>

 530       Liabilities:Visa
 531 </pre></blockquote>
 532
 533 <p>The concept seemed interesting enough for me to check it out and
 534 look for others using it.  I found blog posts from
 535 <a href="http://blog.spang.cc/posts/hledger_rocks_my_world/">Christine
 536 Spang</a>,
 537 <a href="http://bugsplat.info/2010-05-23-keeping-finances-with-ledger.html">Pete
 538 Keen</a>,
 539 <a href="http://blog.andrewcantino.com/blog/2010/11/06/command-line-accounting-with-ledger-and-reckon/">Andrew
 540 Cantino</a> and
 541 <a href="http://blog.iphoting.com/blog/2012/11/29/command-line-double-entry-accounting/">Ronald
 542 Ip</a> describing how they use it, as well as a post from
 543 <a href="https://groups.google.com/forum/?fromgroups=#!topic/ledger-cli/r0oWjwbQ9Bo">Bradley
 544 M. Kuhn</a> at the Software Freedom Conservancy.  All seemed like good
 545 recommendations fitting my need.</p>
 546
 547 <p>The <a href="http://packages.qa.debian.org/l/ledger.html">ledger</a>
 548 package is available in Debian Squeeze, while the
 549 <a href="http://packages.qa.debian.org/h/haskell-hledger.html">hledger</a>
 550 package only is available in Debian Sid.  As I use Squeeze, ledger
 551 seemed the best choice to get started.</p>
 552
 553 <p>To get some real data to test on, I wrote a
 554 <a href="http://www.nuug.no/tools/lodo2ledger">web scraper</a> for
 555 <a href="http://www.lodo.no/">LODO</a>, the accounting system used by
 556 the <a href="http://www.nuug.no/">NUUG</a> association, and started to
 557 play with the data set.  I'm not really deeply into accounting, but I
 558 am able to get a simple balance and accounting status for example
 559 using the "<tt>ledger balance</tt>" command.  But I will have to
 560 gather more experience before I know if the ledger way is a good fit
 561 for the organisations I am involved in.</p>

 614       <div class="date"> 6th December 2012</div>
 615       <div class="body"><p>Where I work at the <a href="http://www.uio.no/">University of
 616 Oslo</a>, we use the
 617 <a href="http://sourceforge.net/projects/cerebrum/">Cerebrum user
 618 administration system</a> to maintain users, groups, DNS, DHCP, etc.
 619 I've known since the system was written that the server is providing
 620 an <a href="http://en.wikipedia.org/wiki/XML-RPC">XML-RPC</a> API, but
 621 I have never spent time to try to figure out how to use it, as we
 622 always use the bofh command line client at work.  Until today.  I want
 623 to script the updating of DNS and DHCP to make it easier to set up
 624 virtual machines.  Here are a few notes on how to use it with
 625 Python.</p>
 626
 627 <p>I started by looking at the source of the Java
 628 <a href="http://cerebrum.svn.sourceforge.net/viewvc/cerebrum/trunk/cerebrum/clients/jbofh/">bofh
 629 client</a>, to figure out how it connected to the API server.  I also
 630 googled for python examples on how to use XML-RPC, and found
 631 <a href="http://tldp.org/HOWTO/XML-RPC-HOWTO/xmlrpc-howto-python.html">a
 632 simple example in</a> the XML-RPC howto.</p>
 633
 634 <p>This simple example code show how to connect, get the list of
 635 commands (as a JSON dump), and how to get the information about the
 636 user currently logged in:</p>
 637
 638 <blockquote><pre>
 639 #!/usr/bin/env python
 640 import getpass
 641 import xmlrpclib
 642 server_url = 'https://cerebrum-uio.uio.no:8000';
 643 username = getpass.getuser()
 644 password = getpass.getpass()
 645 server = xmlrpclib.Server(server_url);
 646 #print server.get_commands(sessionid)
 647 sessionid = server.login(username, password)
 648 print server.run_command(sessionid, "user_info", username)
 649 result = server.logout(sessionid)
 650 print result
 651 </pre></blockquote>
 652
 653 <p>Armed with this knowledge I can now move forward and script the DNS
 654 and DHCP updates I wanted to do.</p>
