  24       <div class="date">19th January 2013</div>
  25       <div class="body"><p>This Christmas my trusty old laptop died.  It died quietly and
  26 suddenly in bed.  With a quiet whimper, it went completely quiet and
  27 black.  The power button was no longer able to turn it on.  It was a
  28 IBM Thinkpad X41, and the best laptop I ever had.  Better than both
  29 Thinkpads X30, X31, X40, X60, X61 and X61S.  Far better than the
  30 Compaq I had before that.  Now I need to find a replacement.  To keep
  31 going during Christmas, I moved the one year old SSD disk to my old
  32 X40 where it fitted (only one I had left that could use it), but it is
  33 not a durable solution.
  34
  35 <p>My laptop needs are fairly modest.  This is my wishlist from when I
  36 got a new one more than 10 years ago.  It still holds true.:)</p>
  37
  38 <ul>
  39
  40 <li>Lightweight (around 1 kg) and small volume (preferably smaller
  41   than A4).</li>
  42 <li>Robust, it will be in my backpack every day.</li>
  43 <li>Three button mouse and a mouse pin instead of touch pad.</li>
  44 <li>Long battery life time.  Preferable a week.</li>
  45 <li>Internal WIFI network card.</li>
  46 <li>Internal Twisted Pair network card.</li>
  47 <li>Some USB slots (2-3 is plenty)</li>
  48 <li>Good keyboard - similar to the Thinkpad.</li>
  49 <li>Video resolution at least 1024x768, with size around 12" (A4 paper
  50 size).</li>
  51 <li>Hardware supported by Debian Stable, ie the default kernel and
  52   X.org packages.</li>
  53 <li>Quiet, preferably fan free (or at least not using the fan most of
  54   the time).
  55
  56 </ul>
  57
  58 <p>You will notice that there are no RAM and CPU requirements in the
  59 list.  The reason is simply that the specifications on laptops the
  60 last 10-15 years have been sufficient for my needs, and I have to look
  61 at other features to choose my laptop.  But are there still made as
  62 robust laptops as my X41?  The Thinkpad X60/X61 proved to be less
  63 robust, and Thinkpads seem to be heading in the wrong direction since
  64 Lenovo took over.  But I've been told that X220 and X1 Carbon might
  65 still be useful.</p>
  66
  67 <p>Perhaps I should rethink my needs, and look for a pad with an
  68 external keyboard?  I'll have to check the
  69 <a href="http://www.linux-laptop.net/">Linux Laptops site</a> for
  70 well-supported laptops, or perhaps just buy one preinstalled from one
  71 of the vendors listed on the <a href="http://linuxpreloaded.com/">Linux
  72 Pre-loaded site</a>.</p>

  86       <div class="date">18th January 2013</div>
  87       <div class="body"><p>Some times I try to figure out which Iceweasel browser plugin to
  88 install to get support for a given MIME type.  Thanks to
  89 <a href="https://wiki.ubuntu.com/MozillaTeam/Plugins">specifications
  90 done by Ubuntu</a> and Mozilla, it is possible to do this in Debian.
  91 Unfortunately, not very many packages provide the needed meta
  92 information, Anyway, here is a small script to look up all browser
  93 plugin packages announcing ther MIME support using this specification:</p>
  94
  95 <pre>
  96 #!/usr/bin/python
  97 import sys
  98 import apt
  99 def pkgs_handling_mimetype(mimetype):
 100     cache = apt.Cache()
 101     cache.open(None)
 102     thepkgs = []
 103     for pkg in cache:
 104         version = pkg.candidate
 105         if version is None:
 106             version = pkg.installed
 107         if version is None:
 108             continue
 109         record = version.record
 110         if not record.has_key('Npp-MimeType'):
 111             continue
 112         mime_types = record['Npp-MimeType'].split(',')
 113         for t in mime_types:
 114             t = t.rstrip().strip()
 115             if t == mimetype:
 116                 thepkgs.append(pkg.name)
 117     return thepkgs
 118 mimetype = "audio/ogg"
 119 if 1 < len(sys.argv):
 120     mimetype = sys.argv[1]
 121 print "Browser plugin packages supporting %s:" % mimetype
 122 for pkg in pkgs_handling_mimetype(mimetype):
 123     print "  %s" %pkg
 124 </pre>
 125
 126 <p>It can be used like this to look up a given MIME type:</p>
 127
 128 <pre>
 129 % ./apt-find-browserplug-for-mimetype
 130 Browser plugin packages supporting audio/ogg:
 131   gecko-mediaplayer
 132 % ./apt-find-browserplug-for-mimetype application/x-shockwave-flash
 133 Browser plugin packages supporting application/x-shockwave-flash:
 134   browser-plugin-gnash
 135 %
 136 </pre>
 137
 138 <p>In Ubuntu this mechanism is combined with support in the browser
 139 itself to query for plugins and propose to install the needed
 140 packages.  It would be great if Debian supported such feature too.  Is
 141 anyone working on adding it?</p>
 142
 143 <p><strong>Update 2013-01-18 14:20</strong>: The Debian BTS
 144 request for icweasel support for this feature is
 145 <a href="http://bugs.debian.org/484010">#484010</a> from 2008 (and
 146 <a href="http://bugs.debian.org/698426">#698426</a> from today).  Lack
 147 of manpower and wish for a different design is the reason thus feature
 148 is not yet in iceweasel from Debian.</p>

 163       <div class="body"><p>The <a href="http://wiki.debian.org/AppStreamDebianProposal">DEP-11
 164 proposal to add AppStream information to the Debian archive</a>, is a
 165 proposal to make it possible for a Desktop application to propose to
 166 the user some package to install to gain support for a given MIME
 167 type, font, library etc. that is currently missing.  With such
 168 mechanism in place, it would be possible for the desktop to
 169 automatically propose and install leocad if some LDraw file is
 170 downloaded by the browser.</p>
 171
 172 <p>To get some idea about the current content of the archive, I decided
 173 to write a simple program to extract all .desktop files from the
 174 Debian archive and look up the claimed MIME support there.  The result
 175 can be found on the
 176 <a href="http://ftp.skolelinux.org/pub/AppStreamTest">Skolelinux FTP
 177 site</a>.  Using the collected information, it become possible to
 178 answer the question in the title.  Here are the 20 most supported MIME
 179 types in Debian stable (Squeeze), testing (Wheezy) and unstable (Sid).
 180 The complete list is available from the link above.</p>

 283       <div class="date">15th January 2013</div>
 284       <div class="body"><p>Yesterday, I wrote about the
 285 <a href="http://people.skolelinux.org/pere/blog/Modalias_strings___a_practical_way_to_map__stuff__to_hardware.html">modalias
 286 values provided by the Linux kernel</a> following my hope for
 287 <a href="http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">better
 288 dongle support in Debian</a>.  Using this knowledge, I have tested how
 289 modalias values attached to package names can be used to map packages
 290 to hardware.  This allow the system to look up and suggest relevant
 291 packages when I plug in some new hardware into my machine, and replace
 292 discover and discover-data as the database used to map hardware to
 293 packages.</p>
 294
 295 <p>I create a modaliases file with entries like the following,
 296 containing package name, kernel module name (if relevant, otherwise
 297 the package name) and globs matching the relevant hardware
 298 modalias.</p>
 299
 300 <p><blockquote>
 301 Package: package-name
 302 <br>Modaliases: module(modaliasglob, modaliasglob, modaliasglob)</p>
 303 </blockquote></p>
 304
 305 <p>It is fairly trivial to write code to find the relevant packages
 306 for a given modalias value using this file.</p>
 307
 308 <p>An entry like this would suggest the video and picture application
 309 cheese for many USB web cameras (interface bus class 0E01):</p>
 310
 311 <p><blockquote>
 312 Package: cheese
 313 <br>Modaliases: cheese(usb:v*p*d*dc*dsc*dp*ic0Eisc01ip*)</p>
 314 </blockquote></p>
 315
 316 <p>An entry like this would suggest the pcmciautils package when a
 317 CardBus bridge (bus class 0607) PCI device is present:</p>
 318
 319 <p><blockquote>
 320 Package: pcmciautils
 321 <br>Modaliases: pcmciautils(pci:v*d*sv*sd*bc06sc07i*)
 322 </blockquote></p>
 323
 324 <p>An entry like this would suggest the package colorhug-client when
 325 plugging in a ColorHug with USB IDs 04D8:F8DA:</p>
 326
 327 <p><blockquote>
 328 Package: colorhug-client
 329 <br>Modaliases: colorhug-client(usb:v04D8pF8DAd*)</p>
 330 </blockquote></p>
 331
 332 <p>I believe the format is compatible with the format of the Packages
 333 file in the Debian archive.  Ubuntu already uses their Packages file
 334 to store their mappings from packages to hardware.</p>
 335
 336 <p>By adding a XB-Modaliases: header in debian/control, any .deb can
 337 announce the hardware it support in a way my prototype understand.
 338 This allow those publishing packages in an APT source outside the
 339 Debian archive as well as those backporting packages to make sure the
 340 hardware mapping are included in the package meta information.  I've
 341 tested such header in the pymissile package, and its modalias mapping
 342 is working as it should with my prototype.  It even made it to Ubuntu
 343 Raring.</p>
 344
 345 <p>To test if it was possible to look up supported hardware using only
 346 the shell tools available in the Debian installer, I wrote a shell
 347 implementation of the lookup code.  The idea is to create files for
 348 each modalias and let the shell do the matching.  Please check out and
 349 try the
 350 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/hw-support-lookup?view=co">hw-support-lookup</a>
 351 shell script.  It run without any extra dependencies and fetch the
 352 hardware mappings from the Debian archive and the subversion
 353 repository where I currently work on my prototype.</p>
 354
 355 <p>When I use it on a machine with a yubikey inserted, it suggest to
 356 install yubikey-personalization:</p>
 357
 358 <p><blockquote>
 359 % ./hw-support-lookup
 360 <br>yubikey-personalization
 361 <br>%
 362 </blockquote></p>
 363
 364 <p>When I run it on my Thinkpad X40 with a PCMCIA/CardBus slot, it
 365 propose to install the pcmciautils package:</p>
 366
 367 <p><blockquote>
 368 % ./hw-support-lookup
 369 <br>pcmciautils
 370 <br>%
 371 </blockquote></p>
 372
 373 <p>If you know of any hardware-package mapping that should be added to
 374 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=co">my
 375 database</a>, please tell me about it.</p>
 376
 377 <p>It could be possible to generate several of the mappings between
 378 packages and hardware.  One source would be to look at packages with
 379 kernel modules, ie packages with *.ko files in /lib/modules/, and
 380 extract their modalias information.  Another would be to look at
 381 packages with udev rules, ie packages with files in
 382 /lib/udev/rules.d/, and extract their vendor/model information to
 383 generate a modalias matching rule.  I have not tested any of these to
 384 see if it work.</p>
 385
 386 <p>If you want to help implementing a system to let us propose what
 387 packages to install when new hardware is plugged into a Debian
 388 machine, please send me an email or talk to me on
 389 <a href="irc://irc.debian.org/%23debian-devel">#debian-devel</a>.</p>

 438 <p><strong>PCI subtype</strong></p>
 439
 440 <p>A typical PCI entry can look like this.  This is an Intel Host
 441 Bridge memory controller:</p>
 442
 443 <p><blockquote>
 444 pci:v00008086d00002770sv00001028sd000001ADbc06sc00i00
 445 </blockquote></p>
 446
 447 <p>This represent these values:</p>
 448
 449 <pre>
 450  v   00008086  (vendor)
 451  d   00002770  (device)
 452  sv  00001028  (subvendor)
 453  sd  000001AD  (subdevice)
 454  bc  06        (bus class)
 455  sc  00        (bus subclass)
 456  i   00        (interface)
 457 </pre>
 458
 459 <p>The vendor/device values are the same values outputted from 'lspci
 460 -n' as 8086:2770.  The bus class/subclass is also shown by lspci as
 461 0600.  The 0600 class is a host bridge.  Other useful bus values are
 462 0300 (VGA compatible card) and 0200 (Ethernet controller).</p>
 463
 464 <p>Not sure how to figure out the interface value, nor what it
 465 means.</p>
 466
 467 <p><strong>USB subtype</strong></p>
 468
 469 <p>Some typical USB entries can look like this.  This is an internal
 470 USB hub in a laptop:</p>
 471
 472 <p><blockquote>
 473 usb:v1D6Bp0001d0206dc09dsc00dp00ic09isc00ip00
 474 </blockquote></p>
 475
 476 <p>Here is the values included in this alias:</p>
 477
 478 <pre>
 479  v    1D6B  (device vendor)
 480  p    0001  (device product)
 481  d    0206  (bcddevice)
 482  dc     09  (device class)
 483  dsc    00  (device subclass)
 484  dp     00  (device protocol)
 485  ic     09  (interface class)
 486  isc    00  (interface subclass)
 487  ip     00  (interface protocol)
 488 </pre>
 489
 490 <p>The 0900 device class/subclass means hub.  Some times the relevant
 491 class is in the interface class section.  For a simple USB web camera,
 492 these alias entries show up:</p>
 493
 494 <p><blockquote>
 495 usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc01ip00
 496 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc02ip00
 497 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc01ip00
 498 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc02ip00
 499 </blockquote></p>
 500
 501 <p>Interface class 0E01 is video control, 0E02 is video streaming (aka
 502 camera), 0101 is audio control device and 0102 is audio streaming (aka
 503 microphone).  Thus this is a camera with microphone included.</p>
 504
 505 <p><strong>ACPI subtype</strong></p>
 506
 507 <p>The ACPI type is used for several non-PCI/USB stuff.  This is an IR
 508 receiver in a Thinkpad X40:</p>
 509
 510 <p><blockquote>

 513
 514 <p>The values between the colons are IDs.</p>
 515
 516 <p><strong>DMI subtype</strong></p>
 517
 518 <p>The DMI table contain lots of information about the computer case
 519 and model.  This is an entry for a IBM Thinkpad X40, fetched from
 520 /sys/devices/virtual/dmi/id/modalias:</p>
 521

 575
 576 <p>The chassis type values are not always accurately set in the DMI
 577 table.  For example my home server is a tower, but the DMI modalias
 578 claim it is a desktop.</p>
 579
 580 <p><strong>SerIO subtype</strong></p>
 581
 582 <p>This type is used for PS/2 mouse plugs.  One example is from my
 583 test machine:</p>
 584
 585 <p><blockquote>
 586 serio:ty01pr00id00ex00

 594   id  00  (id)
 595   ex  00  (extra)
 596 </pre>
 597
 598 <p>This type is supported by the psmouse driver.  I am not sure what
 599 the valid values are.</p>
 600
 601 <p><strong>Other subtypes</strong></p>
 602
 603 <p>There are heaps of other modalias subtypes according to
 604 file2alias.c.  There is the rest of the list from that source: amba,
 605 ap, bcma, ccw, css, eisa, hid, i2c, ieee1394, input, ipack, isapnp,
 606 mdio, of, parisc, pcmcia, platform, scsi, sdio, spi, ssb, vio, virtio,
 607 vmbus, x86cpu and zorro.  I did not spend time documenting all of
 608 these, as they do not seem relevant for my intended use with mapping
 609 hardware to packages when new stuff is inserted during run time.</p>
 610
 611 <p><strong>Looking up kernel modules using modalias values</strong></p>
 612
 613 <p>To check which kernel modules provide support for a given modalias,
 614 one can use the following shell script:</p>
 615
 616 <pre>
 617   for id in $(find /sys -name modalias -print0 | xargs -0 cat | sort -u); do \
 618     echo "$id" ; \
 619     /sbin/modprobe --show-depends "$id"|sed 's/^/  /' ; \
 620   done
 621 </pre>
 622
 623 <p>The output can look like this (only the first few entries as the
 624 list is very long on my test machine):</p>
 625
 626 <pre>

 665       <div class="body"><p>As part of my investigation on how to improve the support in Debian
 666 for hardware dongles, I dug up my old Mark and Spencer USB Rocket
 667 Launcher and updated the Debian package
 668 <a href="http://packages.qa.debian.org/pymissile">pymissile</a> to make
 669 sure udev will fix the device permissions when it is plugged in.  I
 670 also added a "Modaliases" header to test it in the Debian archive and
 671 hopefully make the package be proposed by jockey in Ubuntu when a user
 672 plug in his rocket launcher.  In the process I moved the source to a
 673 git repository under collab-maint, to make it easier for any DD to
 674 contribute.  <a href="http://code.google.com/p/pymissile/">Upstream</a>
 675 is not very active, but the software still work for me even after five
 676 years of relative silence.  The new git repository is not listed in
 677 the uploaded package yet, because I want to test the other changes a
 678 bit more before I upload the new version.  If you want to check out
 679 the new version with a .desktop file included, visit the

 696       <div class="date"> 9th January 2013</div>
 697       <div class="body"><p>One thing that annoys me with Debian and Linux distributions in
 698 general, is that there is a great package management system with the
 699 ability to automatically install software packages by downloading them
 700 from the distribution mirrors, but no way to get it to automatically
 701 install the packages I need to use the hardware I plug into my
 702 machine.  Even if the package to use it is easily available from the
 703 Linux distribution.  When I plug in a LEGO Mindstorms NXT, it could
 704 suggest to automatically install the python-nxt, nbc and t2n packages
 705 I need to talk to it.  When I plug in a Yubikey, it could propose the
 706 yubikey-personalization package.  The information required to do this
 707 is available, but no-one have pulled all the pieces together.</p>
 708
 709 <p>Some years ago, I proposed to
 710 <a href="http://lists.debian.org/debian-devel/2010/05/msg01206.html">use
 711 the discover subsystem to implement this</a>.  The idea is fairly
 712 simple:
 713
 714 <ul>
 715
 716 <li>Add a desktop entry in /usr/share/autostart/ pointing to a program
 717   starting when a user log in.</li>
 718
 719 <li>Set this program up to listen for kernel events emitted when new
 720   hardware is inserted into the computer.</li>
 721
 722 <li>When new hardware is inserted, look up the hardware ID in a
 723   database mapping to packages, and take note of any non-installed
 724   packages.</li>
 725
 726 <li>Show a message to the user proposing to install the discovered
 727   package, and make it easy to install it.</li>
 728
 729 </ul>
 730
 731 <p>I am not sure what the best way to implement this is, but my
 732 initial idea was to use dbus events to discover new hardware, the
 733 discover database to find packages and
 734 <a href="http://www.packagekit.org/">PackageKit</a> to install
 735 packages.</p>
 736
 737 <p>Yesterday, I found time to try to implement this idea, and the
 738 draft package is now checked into
 739 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">the
 740 Debian Edu subversion repository</a>.  In the process, I updated the
 741 <a href="http://packages.qa.debian.org/d/discover-data.html">discover-data</a>
 742 package to map the USB ids of LEGO Mindstorms and Yubikey devices to
 743 the relevant packages in Debian, and uploaded a new version
 744 2.2013.01.09 to unstable.  I also discovered that the current
 745 <a href="http://packages.qa.debian.org/d/discover.html">discover</a>
 746 package in Debian no longer discovered any USB devices, because
 747 /proc/bus/usb/devices is no longer present.  I ported it to use
 748 libusb as a fall back option to get it working.  The fixed package
 749 version 2.1.2-6 is now in experimental (didn't upload it to unstable
 750 because of the freeze).</p>
 751
 752 <p>With this prototype in place, I can insert my Yubikey, and get this
 753 desktop notification to show up (only once, the first time it is
 754 inserted):</p>
 755
 756 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2013-01-09-hw-autoinstall.png"></p>
 757
 758 <p>For this prototype to be really useful, some way to automatically
 759 install the proposed packages by pressing the "Please install
 760 program(s)" button should to be implemented.</p>
 761
 762 <p>If this idea seem useful to you, and you want to help make it
 763 happen, please help me update the discover-data database with mappings
 764 from hardware to Debian packages.  Check if 'discover-pkginstall -l'
 765 list the package you would like to have installed when a given
 766 hardware device is inserted into your computer, and report bugs using
 767 reportbug if it isn't.  Or, if you know of a better way to provide
 768 such mapping, please let me know.</p>
 769
 770 <p>This prototype need more work, and there are several questions that
 771 should be considered before it is ready for production use.  Is dbus
 772 the correct way to detect new hardware?  At the moment I look for HAL
 773 dbus events on the system bus, because that is the events I could see
 774 on my Debian Squeeze KDE desktop.  Are there better events to use?
 775 How should the user be notified?  Is the desktop notification
 776 mechanism the best option, or should the background daemon raise a
 777 popup instead?  How should packages be installed?  When should they
 778 not be installed?</p>
 779
 780 <p>If you want to help getting such feature implemented in Debian,
 781 please send me an email. :)</p>

 928       <div class="date">28th December 2012</div>
 929       <div class="body"><p>I was happy to discover a few days ago that the
 930 <a href="http://www.skolelinux.org/">Skolelinux / Debian Edu</a>
 931 project also this year received a Christmas present from Another
 932 Agency in Trondheim.  NOK 1000,- showed up on our donation account
 933 December 24th.  I want to express our thanks for this very welcome
 934 present.  As the Debian Edu / Skolelinux project is very short on
 935 funding these days, and thus lack the money to do regular developer
 936 gatherings, this donation was most welcome.  One developer gathering
 937 cost around NOK 15&nbsp;000,-, so we need quite a lot more to keep the
 938 development pace we want.  Thus, I hope their example this year is
 939 followed by many others. :)</p>
 940
 941 <p>The public list of donors can be found on
 942 <a href="http://www.linuxiskolen.no/slxdebianlabs/donations.html">the
 943 donation page</a> for the project, which also contain instructions if
 944 you want to donate to the project.</p>
