  25       <div class="body"><p>The <a href="http://wiki.debian.org/AppStreamDebianProposal">DEP-11
  26 proposal to add AppStream information to the Debian archive</a>, is a
  27 proposal to make it possible for a Desktop application to propose to
  28 the user some package to install to gain support for a given MIME
  29 type, font, library etc. that is currently missing.  With such
  30 mechanism in place, it would be possible for the desktop to
  31 automatically propose and install leocad if some LDraw file is
  32 downloaded by the browser.</p>
  33
  34 <p>To get some idea about the current content of the archive, I decided
  35 to write a simple program to extract all .desktop files from the
  36 Debian archive and look up the claimed MIME support there.  The result
  37 can be found on the
  38 <a href="http://ftp.skolelinux.org/pub/AppStreamTest">Skolelinux FTP
  39 site</a>.  Using the collected information, it become possible to
  40 answer the question in the title.  Here are the 20 most supported MIME
  41 types in Debian stable (Squeeze), testing (Wheezy) and unstable (Sid).
  42 The complete list is available from the link above.</p>

 125 <p>I am told that PackageKit can provide an API to access the kind of
 126 information mentioned in DEP-11.  I have not yet had time to look at
 127 it, but hope the PackageKit people in Debian are on top of these
 128 issues.</p>

 142       <div class="date">15th January 2013</div>
 143       <div class="body"><p>Yesterday, I wrote about the
 144 <a href="http://people.skolelinux.org/pere/blog/Modalias_strings___a_practical_way_to_map__stuff__to_hardware.html">modalias
 145 values provided by the Linux kernel</a> following my hope for
 146 <a href="http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">better
 147 dongle support in Debian</a>.  Using this knowledge, I have tested how
 148 modalias values attached to package names can be used to map packages
 149 to hardware.  This allow the system to look up and suggest relevant
 150 packages when I plug in some new hardware into my machine, and replace
 151 discover and discover-data as the database used to map hardware to
 152 packages.</p>
 153
 154 <p>I create a modaliases file with entries like the following,
 155 containing package name, kernel module name (if relevant, otherwise
 156 the package name) and globs matching the relevant hardware
 157 modalias.</p>
 158
 159 <p><blockquote>
 160 Package: package-name
 161 <br>Modaliases: module(modaliasglob, modaliasglob, modaliasglob)</p>
 162 </blockquote></p>
 163
 164 <p>It is fairly trivial to write code to find the relevant packages
 165 for a given modalias value using this file.</p>
 166
 167 <p>An entry like this would suggest the video and picture application
 168 cheese for many USB web cameras (interface bus class 0E01):</p>
 169
 170 <p><blockquote>
 171 Package: cheese
 172 <br>Modaliases: cheese(usb:v*p*d*dc*dsc*dp*ic0Eisc01ip*)</p>
 173 </blockquote></p>
 174
 175 <p>An entry like this would suggest the pcmciautils package when a
 176 CardBus bridge (bus class 0607) PCI device is present:</p>
 177
 178 <p><blockquote>
 179 Package: pcmciautils
 180 <br>Modaliases: pcmciautils(pci:v*d*sv*sd*bc06sc07i*)
 181 </blockquote></p>
 182
 183 <p>An entry like this would suggest the package colorhug-client when
 184 plugging in a ColorHug with USB IDs 04D8:F8DA:</p>
 185
 186 <p><blockquote>
 187 Package: colorhug-client
 188 <br>Modaliases: colorhug-client(usb:v04D8pF8DAd*)</p>
 189 </blockquote></p>
 190
 191 <p>I believe the format is compatible with the format of the Packages
 192 file in the Debian archive.  Ubuntu already uses their Packages file
 193 to store their mappings from packages to hardware.</p>
 194
 195 <p>By adding a XB-Modaliases: header in debian/control, any .deb can
 196 announce the hardware it support in a way my prototype understand.
 197 This allow those publishing packages in an APT source outside the
 198 Debian archive as well as those backporting packages to make sure the
 199 hardware mapping are included in the package meta information.  I've
 200 tested such header in the pymissile package, and its modalias mapping
 201 is working as it should with my prototype.  It even made it to Ubuntu
 202 Raring.</p>
 203
 204 <p>To test if it was possible to look up supported hardware using only
 205 the shell tools available in the Debian installer, I wrote a shell
 206 implementation of the lookup code.  The idea is to create files for
 207 each modalias and let the shell do the matching.  Please check out and
 208 try the
 209 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/hw-support-lookup?view=co">hw-support-lookup</a>
 210 shell script.  It run without any extra dependencies and fetch the
 211 hardware mappings from the Debian archive and the subversion
 212 repository where I currently work on my prototype.</p>
 213
 214 <p>When I use it on a machine with a yubikey inserted, it suggest to
 215 install yubikey-personalization:</p>
 216
 217 <p><blockquote>
 218 % ./hw-support-lookup
 219 <br>yubikey-personalization
 220 <br>%
 221 </blockquote></p>
 222
 223 <p>When I run it on my Thinkpad X40 with a PCMCIA/CardBus slot, it
 224 propose to install the pcmciautils package:</p>
 225
 226 <p><blockquote>
 227 % ./hw-support-lookup
 228 <br>pcmciautils
 229 <br>%
 230 </blockquote></p>
 231
 232 <p>If you know of any hardware-package mapping that should be added to
 233 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=co">my
 234 database</a>, please tell me about it.</p>
 235
 236 <p>It could be possible to generate several of the mappings between
 237 packages and hardware.  One source would be to look at packages with
 238 kernel modules, ie packages with *.ko files in /lib/modules/, and
 239 extract their modalias information.  Another would be to look at
 240 packages with udev rules, ie packages with files in
 241 /lib/udev/rules.d/, and extract their vendor/model information to
 242 generate a modalias matching rule.  I have not tested any of these to
 243 see if it work.</p>
 244
 245 <p>If you want to help implementing a system to let us propose what
 246 packages to install when new hardware is plugged into a Debian
 247 machine, please send me an email or talk to me on
 248 <a href="irc://irc.debian.org/%23debian-devel">#debian-devel</a>.</p>

 263       <div class="body"><p>While looking into how to look up Debian packages based on hardware
 264 information, to find the packages that support a given piece of

 271 <p><strong>Modalias decoded</strong></p>
 272
 273 <p>This document try to explain what the different types of modalias
 274 values stands for.  It is in part based on information from
 275 &lt;URL: <a href="https://wiki.archlinux.org/index.php/Modalias">https://wiki.archlinux.org/index.php/Modalias</a> &gt;,
 276 &lt;URL: <a href="http://unix.stackexchange.com/questions/26132/how-to-assign-usb-driver-to-device">http://unix.stackexchange.com/questions/26132/how-to-assign-usb-driver-to-device</a> &gt;,

 279
 280 <p>The modalias entries for a given Linux machine can be found using
 281 this shell script:</p>
 282
 283 <pre>
 284 find /sys -name modalias -print0 | xargs -0 cat | sort -u
 285 </pre>
 286
 287 <p>The supported modalias globs for a given kernel module can be found
 288 using modinfo:</p>
 289
 290 <pre>
 291 % /sbin/modinfo psmouse | grep alias:
 292 alias:          serio:ty05pr*id*ex*
 293 alias:          serio:ty01pr*id*ex*
 294 %
 295 </pre>
 296
 297 <p><strong>PCI subtype</strong></p>
 298
 299 <p>A typical PCI entry can look like this.  This is an Intel Host
 300 Bridge memory controller:</p>
 301
 302 <p><blockquote>
 303 pci:v00008086d00002770sv00001028sd000001ADbc06sc00i00
 304 </blockquote></p>
 305
 306 <p>This represent these values:</p>
 307
 308 <pre>
 309  v   00008086  (vendor)
 310  d   00002770  (device)
 311  sv  00001028  (subvendor)
 312  sd  000001AD  (subdevice)
 313  bc  06        (bus class)
 314  sc  00        (bus subclass)
 315  i   00        (interface)
 316 </pre>
 317
 318 <p>The vendor/device values are the same values outputted from 'lspci
 319 -n' as 8086:2770.  The bus class/subclass is also shown by lspci as
 320 0600.  The 0600 class is a host bridge.  Other useful bus values are
 321 0300 (VGA compatible card) and 0200 (Ethernet controller).</p>
 322
 323 <p>Not sure how to figure out the interface value, nor what it
 324 means.</p>
 325
 326 <p><strong>USB subtype</strong></p>
 327
 328 <p>Some typical USB entries can look like this.  This is an internal
 329 USB hub in a laptop:</p>
 330
 331 <p><blockquote>
 332 usb:v1D6Bp0001d0206dc09dsc00dp00ic09isc00ip00
 333 </blockquote></p>
 334
 335 <p>Here is the values included in this alias:</p>
 336
 337 <pre>
 338  v    1D6B  (device vendor)
 339  p    0001  (device product)
 340  d    0206  (bcddevice)
 341  dc     09  (device class)
 342  dsc    00  (device subclass)
 343  dp     00  (device protocol)
 344  ic     09  (interface class)
 345  isc    00  (interface subclass)
 346  ip     00  (interface protocol)
 347 </pre>
 348
 349 <p>The 0900 device class/subclass means hub.  Some times the relevant
 350 class is in the interface class section.  For a simple USB web camera,
 351 these alias entries show up:</p>
 352
 353 <p><blockquote>
 354 usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc01ip00
 355 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc02ip00
 356 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc01ip00
 357 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc02ip00
 358 </blockquote></p>
 359
 360 <p>Interface class 0E01 is video control, 0E02 is video streaming (aka
 361 camera), 0101 is audio control device and 0102 is audio streaming (aka
 362 microphone).  Thus this is a camera with microphone included.</p>
 363
 364 <p><strong>ACPI subtype</strong></p>
 365
 366 <p>The ACPI type is used for several non-PCI/USB stuff.  This is an IR
 367 receiver in a Thinkpad X40:</p>
 368
 369 <p><blockquote>
 370 acpi:IBM0071:PNP0511:
 371 </blockquote></p>
 372
 373 <p>The values between the colons are IDs.</p>
 374
 375 <p><strong>DMI subtype</strong></p>
 376
 377 <p>The DMI table contain lots of information about the computer case
 378 and model.  This is an entry for a IBM Thinkpad X40, fetched from
 379 /sys/devices/virtual/dmi/id/modalias:</p>
 380
 381 <p><blockquote>

 435 <p>The chassis type values are not always accurately set in the DMI

 437 claim it is a desktop.</p>
 438
 439 <p><strong>SerIO subtype</strong></p>
 440
 441 <p>This type is used for PS/2 mouse plugs.  One example is from my
 442 test machine:</p>
 443
 444 <p><blockquote>

 460 <p><strong>Other subtypes</strong></p>
 461
 462 <p>There are heaps of other modalias subtypes according to
 463 file2alias.c.  There is the rest of the list from that source: amba,
 464 ap, bcma, ccw, css, eisa, hid, i2c, ieee1394, input, ipack, isapnp,
 465 mdio, of, parisc, pcmcia, platform, scsi, sdio, spi, ssb, vio, virtio,
 466 vmbus, x86cpu and zorro.  I did not spend time documenting all of
 467 these, as they do not seem relevant for my intended use with mapping
 468 hardware to packages when new stuff is inserted during run time.</p>
 469
 470 <p><strong>Looking up kernel modules using modalias values</strong></p>
 471
 472 <p>To check which kernel modules provide support for a given modalias,
 473 one can use the following shell script:</p>
 474
 475 <pre>
 476   for id in $(find /sys -name modalias -print0 | xargs -0 cat | sort -u); do \
 477     echo "$id" ; \
 478     /sbin/modprobe --show-depends "$id"|sed 's/^/  /' ; \
 479   done
 480 </pre>
 481
 482 <p>The output can look like this (only the first few entries as the
 483 list is very long on my test machine):</p>
 484

 524       <div class="body"><p>As part of my investigation on how to improve the support in Debian
 525 for hardware dongles, I dug up my old Mark and Spencer USB Rocket
 526 Launcher and updated the Debian package
 527 <a href="http://packages.qa.debian.org/pymissile">pymissile</a> to make
 528 sure udev will fix the device permissions when it is plugged in.  I
 529 also added a "Modaliases" header to test it in the Debian archive and
 530 hopefully make the package be proposed by jockey in Ubuntu when a user
 531 plug in his rocket launcher.  In the process I moved the source to a
 532 git repository under collab-maint, to make it easier for any DD to
 533 contribute.  <a href="http://code.google.com/p/pymissile/">Upstream</a>
 534 is not very active, but the software still work for me even after five
 535 years of relative silence.  The new git repository is not listed in
 536 the uploaded package yet, because I want to test the other changes a
 537 bit more before I upload the new version.  If you want to check out
 538 the new version with a .desktop file included, visit the
 539 <a href="http://anonscm.debian.org/gitweb/?p=collab-maint/pymissile.git">gitweb

 555       <div class="date"> 9th January 2013</div>
 556       <div class="body"><p>One thing that annoys me with Debian and Linux distributions in
 557 general, is that there is a great package management system with the
 558 ability to automatically install software packages by downloading them
 559 from the distribution mirrors, but no way to get it to automatically
 560 install the packages I need to use the hardware I plug into my
 561 machine.  Even if the package to use it is easily available from the
 562 Linux distribution.  When I plug in a LEGO Mindstorms NXT, it could
 563 suggest to automatically install the python-nxt, nbc and t2n packages
 564 I need to talk to it.  When I plug in a Yubikey, it could propose the
 565 yubikey-personalization package.  The information required to do this
 566 is available, but no-one have pulled all the pieces together.</p>
 567
 568 <p>Some years ago, I proposed to
 569 <a href="http://lists.debian.org/debian-devel/2010/05/msg01206.html">use
 570 the discover subsystem to implement this</a>.  The idea is fairly
 571 simple:
 572
 573 <ul>
 574
 575 <li>Add a desktop entry in /usr/share/autostart/ pointing to a program
 576   starting when a user log in.</li>
 577
 578 <li>Set this program up to listen for kernel events emitted when new
 579   hardware is inserted into the computer.</li>
 580
 581 <li>When new hardware is inserted, look up the hardware ID in a
 582   database mapping to packages, and take note of any non-installed
 583   packages.</li>
 584
 585 <li>Show a message to the user proposing to install the discovered
 586   package, and make it easy to install it.</li>
 587
 588 </ul>
 589
 590 <p>I am not sure what the best way to implement this is, but my
 591 initial idea was to use dbus events to discover new hardware, the
 592 discover database to find packages and
 593 <a href="http://www.packagekit.org/">PackageKit</a> to install
 594 packages.</p>
 595
 596 <p>Yesterday, I found time to try to implement this idea, and the
 597 draft package is now checked into
 598 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">the
 599 Debian Edu subversion repository</a>.  In the process, I updated the
 600 <a href="http://packages.qa.debian.org/d/discover-data.html">discover-data</a>
 601 package to map the USB ids of LEGO Mindstorms and Yubikey devices to
 602 the relevant packages in Debian, and uploaded a new version
 603 2.2013.01.09 to unstable.  I also discovered that the current
 604 <a href="http://packages.qa.debian.org/d/discover.html">discover</a>
 605 package in Debian no longer discovered any USB devices, because
 606 /proc/bus/usb/devices is no longer present.  I ported it to use
 607 libusb as a fall back option to get it working.  The fixed package
 608 version 2.1.2-6 is now in experimental (didn't upload it to unstable
 609 because of the freeze).</p>
 610
 611 <p>With this prototype in place, I can insert my Yubikey, and get this
 612 desktop notification to show up (only once, the first time it is
 613 inserted):</p>
 614
 615 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2013-01-09-hw-autoinstall.png"></p>
 616
 617 <p>For this prototype to be really useful, some way to automatically
 618 install the proposed packages by pressing the "Please install
 619 program(s)" button should to be implemented.</p>
 620
 621 <p>If this idea seem useful to you, and you want to help make it
 622 happen, please help me update the discover-data database with mappings
 623 from hardware to Debian packages.  Check if 'discover-pkginstall -l'
 624 list the package you would like to have installed when a given
 625 hardware device is inserted into your computer, and report bugs using
 626 reportbug if it isn't.  Or, if you know of a better way to provide
 627 such mapping, please let me know.</p>
 628
 629 <p>This prototype need more work, and there are several questions that
 630 should be considered before it is ready for production use.  Is dbus
 631 the correct way to detect new hardware?  At the moment I look for HAL
 632 dbus events on the system bus, because that is the events I could see
 633 on my Debian Squeeze KDE desktop.  Are there better events to use?
 634 How should the user be notified?  Is the desktop notification
 635 mechanism the best option, or should the background daemon raise a
 636 popup instead?  How should packages be installed?  When should they
 637 not be installed?</p>
 638
 639 <p>If you want to help getting such feature implemented in Debian,
 640 please send me an email. :)</p>

 789 <a href="http://www.skolelinux.org/">Skolelinux / Debian Edu</a>
 790 project also this year received a Christmas present from Another
 791 Agency in Trondheim.  NOK 1000,- showed up on our donation account
 792 December 24th.  I want to express our thanks for this very welcome
 793 present.  As the Debian Edu / Skolelinux project is very short on
 794 funding these days, and thus lack the money to do regular developer
 795 gatherings, this donation was most welcome.  One developer gathering
 796 cost around NOK 15&nbsp;000,-, so we need quite a lot more to keep the
 797 development pace we want.  Thus, I hope their example this year is
 798 followed by many others. :)</p>

 821 <p><a href="http://www.bitcoin.org/">Bitcoin</a>, the digital
 822 decentralised "currency" that allow people to transfer bitcoins
 823 between each other with minimal overhead, is a very interesting
 824 experiment.  And as I wrote a few days ago, the bitcoin situation in
 825 <a href="http://www.debian.org/">Debian</a> is about to improve a bit.
 826 The <a href="http://packages.qa.debian.org/bitcoin">new debian source
 827 package</a> (version 0.7.2-2) was uploaded yesterday, and is waiting
 828 in <a href="http://ftp-master.debian.org/new.html">the NEW queue</A>
 829 for one of the ftpmasters to approve the new bitcoin-qt package
 830 name.</p>
 831
 832 <p>And thanks to the great work of Jonas and the rest of the bitcoin
 833 team in Debian, you can easily test the package in Debian Squeeze
 834 using the following steps to get a set of working packages:</p>
 835
 836 <blockquote><pre>
 837 git clone git://git.debian.org/git/collab-maint/bitcoin
 838 cd bitcoin
 839 DEB_MAINTAINER_MODE=1 DEB_BUILD_OPTIONS=noupnp fakeroot debian/rules clean
 840 DEB_BUILD_OPTIONS=noupnp git-buildpackage --git-ignore-new
 841 </pre></blockquote>

 843 <p>You might have to install some build dependencies as well.  The
 844 list of commands should give you two packages, bitcoind and
 845 bitcoin-qt, ready for use in a Squeeze environment.  Note that the
 846 client will download the complete set of bitcoin "blocks", which need
 847 around 5.6 GiB of data on my machine at the moment.  Make sure your
 848 ~/.bitcoin/ directory have lots of spare room if you want to download
 849 all the blocks.  The client will warn if the disk is getting full, so
 850 there is not really a problem if you got too little room, but you will
 851 not be able to get all the features out of the client.</p>
 852
 853 <p>As usual, if you use bitcoin and want to show your support of my
 854 activities, please send Bitcoin donations to my address

 869       <div class="date">21st December 2012</div>
 870       <div class="body"><p>It has been a while since I wrote about
 871 <a href="http://www.bitcoin.org/">bitcoin</a>, the decentralised
 872 peer-to-peer based crypto-currency, and the reason is simply that I
 873 have been busy elsewhere.  But two days ago, I started looking at the
 874 state of <a href="http://packages.qa.debian.org/bitcoin">bitcoin in
 875 Debian</a> again to try to recover my old bitcoin wallet.  The package
 876 is now maintained by a
 877 <a href="https://alioth.debian.org/projects/pkg-bitcoin/">team of
 878 people</a>, and the grunt work had already been done by this team.  We
 879 owe a huge thank you to all these team members. :)
 880 But I was sad to discover that the bitcoin client is missing in
 881 Wheezy.  It is only available in Sid (and an outdated client from
 882 backports).  The client had several RC bugs registered in BTS blocking
 883 it from entering testing.  To try to help the team and improve the
 884 situation, I spent some time providing patches and triaging the bug
 885 reports.  I also had a look at the bitcoin package available from Matt
 886 Corallo in a
 887 <a href="https://launchpad.net/~bitcoin/+archive/bitcoin">PPA for
 888 Ubuntu</a>, and moved the useful pieces from that version into the
 889 Debian package.</p>
 890
 891 <p>After checking with the main package maintainer Jonas Smedegaard on
 892 IRC, I pushed several patches into the collab-maint git repository to
 893 improve the package.  It now contains fixes for the RC issues (not from
 894 me, but fixed by Scott Howard), build rules for a Qt GUI client
 895 package, konqueror support for the bitcoin: URI and bash completion
 896 setup.  As I work on Debian Squeeze, I also created
 897 <a href="http://lists.alioth.debian.org/pipermail/pkg-bitcoin-devel/Week-of-Mon-20121217/000041.html">a
 898 patch to backport</a> the latest version.  Jonas is going to look at
 899 it and try to integrate it into the git repository before uploading a
 900 new version to unstable.
 901
 902 <p>I would very much like bitcoin to succeed, to get rid of the
 903 centralized control currently exercised in the monetary system.  I
 904 find it completely unacceptable that the USA government is collecting
 905 transaction data for almost all international money transfers (most are done in USD and transaction logs shipped to the spooks), and
 906 that the major credit card companies can block legal money
 907 transactions to Wikileaks.  But for bitcoin to succeed, more people
 908 need to use bitcoins, and more people need to accept bitcoins when
 909 they sell products and services.  Improving the bitcoin support in
 910 Debian is a small step in the right direction, but not enough.
 911 Unfortunately the user experience when browsing the web and wanting to
 912 pay with bitcoin is still not very good.  The bitcoin: URI is a step
 913 in the right direction, but need to work in most or every browser in
 914 use.  Also the bitcoin-qt client is too heavy to fire up to do a
 915 quick transaction.  I believe there are other clients available, but
 916 have not tested them.</p>
 917
 918 <p>My
 919 <a href="http://people.skolelinux.org/pere/blog/Now_accepting_bitcoins___anonymous_and_distributed_p2p_crypto_money.html">experiment
 920 with bitcoins</a> showed that at least some of my readers use bitcoin.
 921 I received 20.15 BTC so far on the address I provided in my blog two
 922 years ago, as can be
 923 <a href="http://blockexplorer.com/address/15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b">seen
 924 on the blockexplorer service</a>.  Thank you everyone for your
 925 donation.  The blockexplorer service demonstrates quite well that
 926 bitcoin is not quite anonymous and untracked. :) I wonder if the
 927 number of users have gone up since then.  If you use bitcoin and want
 928 to show your support of my activity, please send Bitcoin donations to
 929 the same address as last time,
