  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>

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

 266       <div class="body"><p>While looking into how to look up Debian packages based on hardware
 267 information, to find the packages that support a given piece of
 268 hardware, I refreshed my memory regarding modalias values, and decided
 269 to document the details.  Here are my findings so far, also available

 274 <p><strong>Modalias decoded</strong></p>
 275
 276 <p>This document try to explain what the different types of modalias
 277 values stands for.  It is in part based on information from
 278 &lt;URL: <a href="https://wiki.archlinux.org/index.php/Modalias">https://wiki.archlinux.org/index.php/Modalias</a> &gt;,
 279 &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;,

 282
 283 <p>The modalias entries for a given Linux machine can be found using
 284 this shell script:</p>
 285
 286 <pre>
 287 find /sys -name modalias -print0 | xargs -0 cat | sort -u
 288 </pre>
 289
 290 <p>The supported modalias globs for a given kernel module can be found
 291 using modinfo:</p>
 292
 293 <pre>
 294 % /sbin/modinfo psmouse | grep alias:
 295 alias:          serio:ty05pr*id*ex*
 296 alias:          serio:ty01pr*id*ex*
 297 %
 298 </pre>
 299
 300 <p><strong>PCI subtype</strong></p>
 301
 302 <p>A typical PCI entry can look like this.  This is an Intel Host
 303 Bridge memory controller:</p>
 304
 305 <p><blockquote>
 306 pci:v00008086d00002770sv00001028sd000001ADbc06sc00i00
 307 </blockquote></p>
 308
 309 <p>This represent these values:</p>
 310
 311 <pre>
 312  v   00008086  (vendor)
 313  d   00002770  (device)
 314  sv  00001028  (subvendor)
 315  sd  000001AD  (subdevice)
 316  bc  06        (bus class)
 317  sc  00        (bus subclass)
 318  i   00        (interface)
 319 </pre>
 320
 321 <p>The vendor/device values are the same values outputted from 'lspci
 322 -n' as 8086:2770.  The bus class/subclass is also shown by lspci as
 323 0600.  The 0600 class is a host bridge.  Other useful bus values are
 324 0300 (VGA compatible card) and 0200 (Ethernet controller).</p>
 325
 326 <p>Not sure how to figure out the interface value, nor what it
 327 means.</p>
 328
 329 <p><strong>USB subtype</strong></p>
 330
 331 <p>Some typical USB entries can look like this.  This is an internal
 332 USB hub in a laptop:</p>
 333
 334 <p><blockquote>
 335 usb:v1D6Bp0001d0206dc09dsc00dp00ic09isc00ip00
 336 </blockquote></p>
 337
 338 <p>Here is the values included in this alias:</p>
 339
 340 <pre>
 341  v    1D6B  (device vendor)
 342  p    0001  (device product)
 343  d    0206  (bcddevice)
 344  dc     09  (device class)
 345  dsc    00  (device subclass)
 346  dp     00  (device protocol)
 347  ic     09  (interface class)
 348  isc    00  (interface subclass)
 349  ip     00  (interface protocol)
 350 </pre>
 351
 352 <p>The 0900 device class/subclass means hub.  Some times the relevant
 353 class is in the interface class section.  For a simple USB web camera,
 354 these alias entries show up:</p>
 355
 356 <p><blockquote>
 357 usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc01ip00
 358 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc02ip00
 359 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc01ip00
 360 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc02ip00
 361 </blockquote></p>
 362
 363 <p>Interface class 0E01 is video control, 0E02 is video streaming (aka
 364 camera), 0101 is audio control device and 0102 is audio streaming (aka
 365 microphone).  Thus this is a camera with microphone included.</p>
 366
 367 <p><strong>ACPI subtype</strong></p>
 368
 369 <p>The ACPI type is used for several non-PCI/USB stuff.  This is an IR
 370 receiver in a Thinkpad X40:</p>
 371
 372 <p><blockquote>
 373 acpi:IBM0071:PNP0511:
 374 </blockquote></p>
 375
 376 <p>The values between the colons are IDs.</p>
 377
 378 <p><strong>DMI subtype</strong></p>
 379
 380 <p>The DMI table contain lots of information about the computer case
 381 and model.  This is an entry for a IBM Thinkpad X40, fetched from
 382 /sys/devices/virtual/dmi/id/modalias:</p>
 383
 384 <p><blockquote>

 440 claim it is a desktop.</p>
 441

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

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

 558       <div class="date"> 9th January 2013</div>
 559       <div class="body"><p>One thing that annoys me with Debian and Linux distributions in
 560 general, is that there is a great package management system with the
 561 ability to automatically install software packages by downloading them
 562 from the distribution mirrors, but no way to get it to automatically
 563 install the packages I need to use the hardware I plug into my
 564 machine.  Even if the package to use it is easily available from the
 565 Linux distribution.  When I plug in a LEGO Mindstorms NXT, it could
 566 suggest to automatically install the python-nxt, nbc and t2n packages
 567 I need to talk to it.  When I plug in a Yubikey, it could propose the
 568 yubikey-personalization package.  The information required to do this
 569 is available, but no-one have pulled all the pieces together.</p>
 570
 571 <p>Some years ago, I proposed to
 572 <a href="http://lists.debian.org/debian-devel/2010/05/msg01206.html">use
 573 the discover subsystem to implement this</a>.  The idea is fairly
 574 simple:
 575
 576 <ul>
 577
 578 <li>Add a desktop entry in /usr/share/autostart/ pointing to a program
 579   starting when a user log in.</li>
 580
 581 <li>Set this program up to listen for kernel events emitted when new
 582   hardware is inserted into the computer.</li>
 583
 584 <li>When new hardware is inserted, look up the hardware ID in a
 585   database mapping to packages, and take note of any non-installed
 586   packages.</li>
 587
 588 <li>Show a message to the user proposing to install the discovered
 589   package, and make it easy to install it.</li>
 590
 591 </ul>
 592
 593 <p>I am not sure what the best way to implement this is, but my
 594 initial idea was to use dbus events to discover new hardware, the
 595 discover database to find packages and
 596 <a href="http://www.packagekit.org/">PackageKit</a> to install
 597 packages.</p>
 598
 599 <p>Yesterday, I found time to try to implement this idea, and the
 600 draft package is now checked into
 601 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">the
 602 Debian Edu subversion repository</a>.  In the process, I updated the
 603 <a href="http://packages.qa.debian.org/d/discover-data.html">discover-data</a>
 604 package to map the USB ids of LEGO Mindstorms and Yubikey devices to
 605 the relevant packages in Debian, and uploaded a new version
 606 2.2013.01.09 to unstable.  I also discovered that the current
 607 <a href="http://packages.qa.debian.org/d/discover.html">discover</a>
 608 package in Debian no longer discovered any USB devices, because
 609 /proc/bus/usb/devices is no longer present.  I ported it to use
 610 libusb as a fall back option to get it working.  The fixed package
 611 version 2.1.2-6 is now in experimental (didn't upload it to unstable
 612 because of the freeze).</p>
 613
 614 <p>With this prototype in place, I can insert my Yubikey, and get this
 615 desktop notification to show up (only once, the first time it is
 616 inserted):</p>
 617
 618 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2013-01-09-hw-autoinstall.png"></p>
 619
 620 <p>For this prototype to be really useful, some way to automatically
 621 install the proposed packages by pressing the "Please install
 622 program(s)" button should to be implemented.</p>
 623
 624 <p>If this idea seem useful to you, and you want to help make it
 625 happen, please help me update the discover-data database with mappings
 626 from hardware to Debian packages.  Check if 'discover-pkginstall -l'
 627 list the package you would like to have installed when a given
 628 hardware device is inserted into your computer, and report bugs using
 629 reportbug if it isn't.  Or, if you know of a better way to provide
 630 such mapping, please let me know.</p>
 631
 632 <p>This prototype need more work, and there are several questions that
 633 should be considered before it is ready for production use.  Is dbus
 634 the correct way to detect new hardware?  At the moment I look for HAL
 635 dbus events on the system bus, because that is the events I could see
 636 on my Debian Squeeze KDE desktop.  Are there better events to use?
 637 How should the user be notified?  Is the desktop notification
 638 mechanism the best option, or should the background daemon raise a
 639 popup instead?  How should packages be installed?  When should they
 640 not be installed?</p>
 641
 642 <p>If you want to help getting such feature implemented in Debian,
 643 please send me an email. :)</p>

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

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

 825 decentralised "currency" that allow people to transfer bitcoins
 826 between each other with minimal overhead, is a very interesting
 827 experiment.  And as I wrote a few days ago, the bitcoin situation in

 829 The <a href="http://packages.qa.debian.org/bitcoin">new debian source

 846 <p>You might have to install some build dependencies as well.  The
 847 list of commands should give you two packages, bitcoind and
 848 bitcoin-qt, ready for use in a Squeeze environment.  Note that the
 849 client will download the complete set of bitcoin "blocks", which need
 850 around 5.6 GiB of data on my machine at the moment.  Make sure your
 851 ~/.bitcoin/ directory have lots of spare room if you want to download
 852 all the blocks.  The client will warn if the disk is getting full, so
 853 there is not really a problem if you got too little room, but you will
 854 not be able to get all the features out of the client.</p>
 855
 856 <p>As usual, if you use bitcoin and want to show your support of my
 857 activities, please send Bitcoin donations to my address

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