-the Debian support for pluggable hardware devices</a>. Now my

+ <description><p>I 2011 raderte et stortingsflertall bestående av Høyre og
+Arbeiderpartiet vekk en betydelig del av privatsfæren til det norske
+folk. Det ble vedtatt at det skulle registreres og lagres i et halvt
+år hvor alle som bærer på en mobiltelefon befinner seg, hvem de
+snakker med og hvor lenge de snakket sammen. Det skal også
+registreres hvem de sendte SMS-meldinger til, hvem en har sendt epost
+til, og hvilke nett-tjenere en besøkte. Saken er kjent som
+<a href="http://beta.holderdeord.no/issues/innfore-datalagringsdirektivet">Datalagringsdirektivet
+(DLD)</a>, og innebærer at alle innbyggerne og andre innenfor Norges
+grenser overvåkes døgnet rundt. Det ble i praksis innført brev og
+besøkskontroll av hele befolkningen. Rapporter fra de landene som
+allerede har innført slik total lagring av borgernes
+kommunikasjonsmønstre forteller at det ikke hjelper i
+kriminalitetsbekjempelsen. Den norske prislappen blir mange hundre
+millioner, uten at det ser ut til å bidra positivt til politiets
+arbeide. Jeg synes flere hundre millioner i stedet burde vært brukt
+på noe som kan dokumenteres å ha effekt i kriminalitetsbekjempelsen.
+Se mer på
+<a href="http://no.wikipedia.org/wiki/Datalagringsdirektivet">Wikipedia</a>
+og <a href="http://www.uhuru.biz/?cat=84">Jon Wessel-Aas</a>.</p>
+
+<p>Hva er problemet, tenkter du kanskje? Et åpenbart problem er at
+medienes kildevern i praksis blir radert ut. Den innsamlede
+informasjonen gjør det mulig å finne ut hvem som har snakket med
+journalister på telefon, SMS og epost, og hvem som har vært i nærheten
+av journalister så sant begge bar med seg en telefon. Et annet er at
+advokatvernet blir sterkt redusert, der politiet kan finne ut hvem
+som har snakket med en advokat når, eller vært i møter en med advokat.
+Et tredje er at svært personlig informasjon kan avledes fra hvilke
+nettsteder en har besøkt. Har en besøkt hivnorge.no,
+swingersnorge.com eller andre sider som kan brukes til avlede
+interesser som hører til privatsfæren, vil denne informasjonen være
+tilgjengelig takket være datalagringsdirektivet.</p>
+
+<p>De fleste partiene var mot, kun to partier stemte for. Høyre og
+Arbeiderpartiet. Og både Høyre og Arbeiderpartiet i Oslo har
+DLD-forkjempere på toppen av sine lister (har ikke sjekket de andre
+fylkene). Det er dermed helt uaktuelt for meg å stemme på disse
+partiene. Her er oversikten over partienes valglister i Oslo, med
+informasjon om hvem som stemte hva i første DLD-votering i Stortinget,
+basert på informasjon fra mine venner i
+<a href="http://beta.holderdeord.no/votes/1301946411e">Holder de
+Ord</a> samt <a href="http://data.stortinget.no/">data.stortinget.no</a>.

+<p>Hvilket parti får så min stemme i år. Jeg tror det blir

-<p>I still need to come up with a better name for the system. Here
-are some screen shots showing the prototype in action. First the
-notification, then the password request, and finally the request to
-approve all the dependencies. Sorry for the Norwegian Bokmål GUI.</p>

-<p>The prototype still need to be improved with longer timeouts, but
-is already useful. The database of hardware to package mappings also
-need more work. It is currently compatible with the Ubuntu way of
-storing such information in the package control file, but could be
-changed to use other formats instead or in addition to the current
-method. I've dropped the use of discover for this mapping, as the
-modalias approach is more flexible and easier to use on Linux as long
-as the Linux kernel expose its modalias strings directly.</p>
-
-<p><strong>Update 2013-01-21 16:50</strong>: Due to popular demand,
-here is the command required to check out and build the source: Use
-'<tt>svn checkout
-svn://svn.debian.org/debian-edu/trunk/src/hw-support-handler/; cd
-hw-support-handler; debuild</tt>'. If you lack debuild, install the
-devscripts package.</p>

- <description><p>This Christmas my trusty old laptop died. It died quietly and
-suddenly in bed. With a quiet whimper, it went completely quiet and
-black. The power button was no longer able to turn it on. It was a
-IBM Thinkpad X41, and the best laptop I ever had. Better than both
-Thinkpads X30, X31, X40, X60, X61 and X61S. Far better than the
-Compaq I had before that. Now I need to find a replacement. To keep
-going during Christmas, I moved the one year old SSD disk to my old
-X40 where it fitted (only one I had left that could use it), but it is
-not a durable solution.

+ <description><p>The second wheezy based beta release of Debian Edu was wrapped up
+today, slightly delayed because of some bugs in the initial Windows
+integration fixes . This is the release announcement:</p>
+
+<p><strong>New features for Debian Edu 7.1+edu0~b1 released 2013-08-22</strong></p>
+
+<p>These are the release notes for Debian Edu / Skolelinux
+7.1+edu0~b1, based on Debian with codename "Wheezy".</p>
+
+<p><strong>About Debian Edu and Skolelinux</strong></p>
+
+<p><a href="http://www.skolelinux.org/">Debian Edu, also known as
+Skolelinux</a>, is a Linux distribution based on Debian providing an
+out-of-the box environment of a completely configured school
+network. Immediately after installation a school server running all
+services needed for a school network is set up just waiting for users
+and machines being added via GOsa², a comfortable Web-UI. A netbooting
+environment is prepared using PXE, so after initial installation of
+the main server from CD or USB stick all other machines can be
+installed via the network. The provided school server provides LDAP
+database and Kerberos authentication service, centralized home
+directories, DHCP server, web proxy and many other services. The
+desktop contains
+<a href="http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html">more
+than 60 educational software packages</a> and more are available from
+the Debian archive, and schools can choose between KDE, Gnome, LXDE
+and Xfce desktop environment.</p>
+
+<p>This is the sixth test release based on Debian Wheezy. Basically this
+is an updated and slightly improved version compared to the Squeeze
+release.</p>
+
+<p>ALERT: Alpha based installations should reinstall or downgrade the
+versions of gosa and libpam-mklocaluser to the ones used in this beta
+release. Both alpha and beta0 based installations should reinstall or
+deal with gosa.conf manually; there are two options: (1) Keep
+gosa.conf and edit this file as outlined
+<a href="http://lists.debian.org/debian-edu/2013/08/msg00127.html">on
+the mailing list</a>. (2) Accept the new version of gosa.conf and
+replace both contained admin password placeholders with the password
+hashes found in the old one (backup copy!). In both cases every user
+need to change their their password to make sure a password is set for
+CIFS access to their home directory.</p>
+
+<p><strong>Software updates</strong></p>
<ul>
-<li>Lightweight (around 1 kg) and small volume (preferably smaller
- than A4).</li>
-<li>Robust, it will be in my backpack every day.</li>
-<li>Three button mouse and a mouse pin instead of touch pad.</li>
-<li>Long battery life time. Preferable a week.</li>
-<li>Internal WIFI network card.</li>
-<li>Internal Twisted Pair network card.</li>
-<li>Some USB slots (2-3 is plenty)</li>
-<li>Good keyboard - similar to the Thinkpad.</li>
-<li>Video resolution at least 1024x768, with size around 12" (A4 paper
-size).</li>
-<li>Hardware supported by Debian Stable, ie the default kernel and
- X.org packages.</li>
-<li>Quiet, preferably fan free (or at least not using the fan most of
- the time).
+<li>Added ssh askpass packages to default installation, to ensure ssh
+ work also without a attached tty.</li>
+<li>Add the command-not-found package to the default installation to
+ make it easier to figure out where to find missing command line
+ tools. Please note, that the command 'update-command-not-found'
+ has to be run as root to actually make it useful (internet access
+ required).</li>
</ul>
-<p>You will notice that there are no RAM and CPU requirements in the
-list. The reason is simply that the specifications on laptops the
-last 10-15 years have been sufficient for my needs, and I have to look
-at other features to choose my laptop. But are there still made as
-robust laptops as my X41? The Thinkpad X60/X61 proved to be less
-robust, and Thinkpads seem to be heading in the wrong direction since
-Lenovo took over. But I've been told that X220 and X1 Carbon might
-still be useful.</p>
-
-<p>Perhaps I should rethink my needs, and look for a pad with an
-external keyboard? I'll have to check the
-<a href="http://www.linux-laptop.net/">Linux Laptops site</a> for
-well-supported laptops, or perhaps just buy one preinstalled from one
-of the vendors listed on the <a href="http://linuxpreloaded.com/">Linux
-Pre-loaded site</a>.</p>

- <title>How to find a browser plugin supporting a given MIME type</title>
- <link>http://people.skolelinux.org/pere/blog/How_to_find_a_browser_plugin_supporting_a_given_MIME_type.html</link>
- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/How_to_find_a_browser_plugin_supporting_a_given_MIME_type.html</guid>
- <pubDate>Fri, 18 Jan 2013 10:40:00 +0100</pubDate>
- <description><p>Some times I try to figure out which Iceweasel browser plugin to
-install to get support for a given MIME type. Thanks to
-<a href="https://wiki.ubuntu.com/MozillaTeam/Plugins">specifications
-done by Ubuntu</a> and Mozilla, it is possible to do this in Debian.
-Unfortunately, not very many packages provide the needed meta
-information, Anyway, here is a small script to look up all browser
-plugin packages announcing ther MIME support using this specification:</p>
-
-<pre>
-#!/usr/bin/python
-import sys
-import apt
-def pkgs_handling_mimetype(mimetype):
- cache = apt.Cache()
- cache.open(None)
- thepkgs = []
- for pkg in cache:
- version = pkg.candidate
- if version is None:
- version = pkg.installed
- if version is None:
- continue
- record = version.record
- if not record.has_key('Npp-MimeType'):
- continue
- mime_types = record['Npp-MimeType'].split(',')
- for t in mime_types:
- t = t.rstrip().strip()
- if t == mimetype:
- thepkgs.append(pkg.name)
- return thepkgs
-mimetype = "audio/ogg"
-if 1 < len(sys.argv):
- mimetype = sys.argv[1]
-print "Browser plugin packages supporting %s:" % mimetype
-for pkg in pkgs_handling_mimetype(mimetype):
- print " %s" %pkg
-</pre>
-
-<p>It can be used like this to look up a given MIME type:</p>
-
-<pre>
-% ./apt-find-browserplug-for-mimetype
-Browser plugin packages supporting audio/ogg:
- gecko-mediaplayer
-% ./apt-find-browserplug-for-mimetype application/x-shockwave-flash
-Browser plugin packages supporting application/x-shockwave-flash:
- browser-plugin-gnash
-%
-</pre>
-
-<p>In Ubuntu this mechanism is combined with support in the browser
-itself to query for plugins and propose to install the needed
-packages. It would be great if Debian supported such feature too. Is
-anyone working on adding it?</p>
-
-<p><strong>Update 2013-01-18 14:20</strong>: The Debian BTS
-request for icweasel support for this feature is
-<a href="http://bugs.debian.org/484010">#484010</a> from 2008 (and
-<a href="http://bugs.debian.org/698426">#698426</a> from today). Lack
-of manpower and wish for a different design is the reason thus feature
-is not yet in iceweasel from Debian.</p>

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

- <title>Using modalias info to find packages handling my hardware</title>

- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Using_modalias_info_to_find_packages_handling_my_hardware.html</guid>
- <pubDate>Tue, 15 Jan 2013 08:00:00 +0100</pubDate>
- <description><p>Yesterday, I wrote about the
-<a href="http://people.skolelinux.org/pere/blog/Modalias_strings___a_practical_way_to_map__stuff__to_hardware.html">modalias
-values provided by the Linux kernel</a> following my hope for
-<a href="http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">better
-dongle support in Debian</a>. Using this knowledge, I have tested how
-modalias values attached to package names can be used to map packages
-to hardware. This allow the system to look up and suggest relevant
-packages when I plug in some new hardware into my machine, and replace
-discover and discover-data as the database used to map hardware to
-packages.</p>
-
-<p>I create a modaliases file with entries like the following,
-containing package name, kernel module name (if relevant, otherwise
-the package name) and globs matching the relevant hardware
-modalias.</p>
-
-<p><blockquote>
-Package: package-name
-<br>Modaliases: module(modaliasglob, modaliasglob, modaliasglob)</p>
-</blockquote></p>
-
-<p>It is fairly trivial to write code to find the relevant packages
-for a given modalias value using this file.</p>
-
-<p>An entry like this would suggest the video and picture application
-cheese for many USB web cameras (interface bus class 0E01):</p>
-
-<p><blockquote>
-Package: cheese
-<br>Modaliases: cheese(usb:v*p*d*dc*dsc*dp*ic0Eisc01ip*)</p>
-</blockquote></p>
-
-<p>An entry like this would suggest the pcmciautils package when a
-CardBus bridge (bus class 0607) PCI device is present:</p>
-
-<p><blockquote>
-Package: pcmciautils
-<br>Modaliases: pcmciautils(pci:v*d*sv*sd*bc06sc07i*)
-</blockquote></p>
-
-<p>An entry like this would suggest the package colorhug-client when
-plugging in a ColorHug with USB IDs 04D8:F8DA:</p>
-
-<p><blockquote>
-Package: colorhug-client
-<br>Modaliases: colorhug-client(usb:v04D8pF8DAd*)</p>
-</blockquote></p>
-
-<p>I believe the format is compatible with the format of the Packages
-file in the Debian archive. Ubuntu already uses their Packages file
-to store their mappings from packages to hardware.</p>
-
-<p>By adding a XB-Modaliases: header in debian/control, any .deb can
-announce the hardware it support in a way my prototype understand.
-This allow those publishing packages in an APT source outside the
-Debian archive as well as those backporting packages to make sure the
-hardware mapping are included in the package meta information. I've
-tested such header in the pymissile package, and its modalias mapping
-is working as it should with my prototype. It even made it to Ubuntu
-Raring.</p>
-
-<p>To test if it was possible to look up supported hardware using only
-the shell tools available in the Debian installer, I wrote a shell
-implementation of the lookup code. The idea is to create files for
-each modalias and let the shell do the matching. Please check out and
-try the
-<a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/hw-support-lookup?view=co">hw-support-lookup</a>
-shell script. It run without any extra dependencies and fetch the
-hardware mappings from the Debian archive and the subversion
-repository where I currently work on my prototype.</p>
-
-<p>When I use it on a machine with a yubikey inserted, it suggest to
-install yubikey-personalization:</p>
-
-<p><blockquote>
-% ./hw-support-lookup
-<br>yubikey-personalization
-<br>%
-</blockquote></p>
-
-<p>When I run it on my Thinkpad X40 with a PCMCIA/CardBus slot, it
-propose to install the pcmciautils package:</p>
-
-<p><blockquote>
-% ./hw-support-lookup
-<br>pcmciautils
-<br>%
-</blockquote></p>
-
-<p>If you know of any hardware-package mapping that should be added to
-<a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=co">my
-database</a>, please tell me about it.</p>
-
-<p>It could be possible to generate several of the mappings between
-packages and hardware. One source would be to look at packages with
-kernel modules, ie packages with *.ko files in /lib/modules/, and
-extract their modalias information. Another would be to look at
-packages with udev rules, ie packages with files in
-/lib/udev/rules.d/, and extract their vendor/model information to
-generate a modalias matching rule. I have not tested any of these to
-see if it work.</p>
-
-<p>If you want to help implementing a system to let us propose what
-packages to install when new hardware is plugged into a Debian
-machine, please send me an email or talk to me on
-<a href="irc://irc.debian.org/%23debian-devel">#debian-devel</a>.</p>

- <description><p>While looking into how to look up Debian packages based on hardware
-information, to find the packages that support a given piece of
-hardware, I refreshed my memory regarding modalias values, and decided
-to document the details. Here are my findings so far, also available
-in
-<a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">the
-Debian Edu subversion repository</a>:
-
-<p><strong>Modalias decoded</strong></p>
-
-<p>This document try to explain what the different types of modalias
-values stands for. It is in part based on information from
-&lt;URL: <a href="https://wiki.archlinux.org/index.php/Modalias">https://wiki.archlinux.org/index.php/Modalias</a> &gt;,
-&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;,
-&lt;URL: <a href="http://code.metager.de/source/history/linux/stable/scripts/mod/file2alias.c">http://code.metager.de/source/history/linux/stable/scripts/mod/file2alias.c</a> &gt; and
-&lt;URL: <a href="http://cvs.savannah.gnu.org/viewvc/dmidecode/dmidecode.c?root=dmidecode&view=markup">http://cvs.savannah.gnu.org/viewvc/dmidecode/dmidecode.c?root=dmidecode&view=markup</a> &gt;.
-
-<p>The modalias entries for a given Linux machine can be found using
-this shell script:</p>
-
-<pre>
-find /sys -name modalias -print0 | xargs -0 cat | sort -u
-</pre>
-
-<p>The supported modalias globs for a given kernel module can be found
-using modinfo:</p>
-
-<pre>
-% /sbin/modinfo psmouse | grep alias:
-alias: serio:ty05pr*id*ex*
-alias: serio:ty01pr*id*ex*
-%
-</pre>
-
-<p><strong>PCI subtype</strong></p>
-
-<p>A typical PCI entry can look like this. This is an Intel Host
-Bridge memory controller:</p>
-
-<p><blockquote>
-pci:v00008086d00002770sv00001028sd000001ADbc06sc00i00
-</blockquote></p>
-
-<p>This represent these values:</p>
-
-<pre>
- v 00008086 (vendor)
- d 00002770 (device)
- sv 00001028 (subvendor)
- sd 000001AD (subdevice)
- bc 06 (bus class)
- sc 00 (bus subclass)
- i 00 (interface)
-</pre>
-
-<p>The vendor/device values are the same values outputted from 'lspci
--n' as 8086:2770. The bus class/subclass is also shown by lspci as
-0600. The 0600 class is a host bridge. Other useful bus values are
-0300 (VGA compatible card) and 0200 (Ethernet controller).</p>
-
-<p>Not sure how to figure out the interface value, nor what it
-means.</p>
-
-<p><strong>USB subtype</strong></p>
-
-<p>Some typical USB entries can look like this. This is an internal
-USB hub in a laptop:</p>
-
-<p><blockquote>
-usb:v1D6Bp0001d0206dc09dsc00dp00ic09isc00ip00
-</blockquote></p>
-
-<p>Here is the values included in this alias:</p>
-
-<pre>
- v 1D6B (device vendor)
- p 0001 (device product)
- d 0206 (bcddevice)
- dc 09 (device class)
- dsc 00 (device subclass)
- dp 00 (device protocol)
- ic 09 (interface class)
- isc 00 (interface subclass)
- ip 00 (interface protocol)
-</pre>
-
-<p>The 0900 device class/subclass means hub. Some times the relevant
-class is in the interface class section. For a simple USB web camera,
-these alias entries show up:</p>
-
-<p><blockquote>
-usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc01ip00
-<br>usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc02ip00
-<br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc01ip00
-<br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc02ip00
-</blockquote></p>
-
-<p>Interface class 0E01 is video control, 0E02 is video streaming (aka
-camera), 0101 is audio control device and 0102 is audio streaming (aka
-microphone). Thus this is a camera with microphone included.</p>
-
-<p><strong>ACPI subtype</strong></p>
-
-<p>The ACPI type is used for several non-PCI/USB stuff. This is an IR
-receiver in a Thinkpad X40:</p>
-
-<p><blockquote>
-acpi:IBM0071:PNP0511:
-</blockquote></p>
-
-<p>The values between the colons are IDs.</p>
-
-<p><strong>DMI subtype</strong></p>
-
-<p>The DMI table contain lots of information about the computer case
-and model. This is an entry for a IBM Thinkpad X40, fetched from
-/sys/devices/virtual/dmi/id/modalias:</p>
-
-<p><blockquote>
-dmi:bvnIBM:bvr1UETB6WW(1.66):bd06/15/2005:svnIBM:pn2371H4G:pvrThinkPadX40:rvnIBM:rn2371H4G:rvrNotAvailable:cvnIBM:ct10:cvrNotAvailable:
-</blockquote></p>
-
-<p>The values present are</p>
-
-<pre>
- bvn IBM (BIOS vendor)
- bvr 1UETB6WW(1.66) (BIOS version)
- bd 06/15/2005 (BIOS date)
- svn IBM (system vendor)
- pn 2371H4G (product name)
- pvr ThinkPadX40 (product version)
- rvn IBM (board vendor)
- rn 2371H4G (board name)
- rvr NotAvailable (board version)
- cvn IBM (chassis vendor)
- ct 10 (chassis type)
- cvr NotAvailable (chassis version)
-</pre>
-
-<p>The chassis type 10 is Notebook. Other interesting values can be
-found in the dmidecode source:</p>
-
-<pre>
- 3 Desktop
- 4 Low Profile Desktop
- 5 Pizza Box
- 6 Mini Tower
- 7 Tower
- 8 Portable
- 9 Laptop
- 10 Notebook
- 11 Hand Held
- 12 Docking Station
- 13 All In One
- 14 Sub Notebook
- 15 Space-saving
- 16 Lunch Box
- 17 Main Server Chassis
- 18 Expansion Chassis
- 19 Sub Chassis
- 20 Bus Expansion Chassis
- 21 Peripheral Chassis
- 22 RAID Chassis
- 23 Rack Mount Chassis
- 24 Sealed-case PC
- 25 Multi-system
- 26 CompactPCI
- 27 AdvancedTCA
- 28 Blade
- 29 Blade Enclosing
-</pre>
-
-<p>The chassis type values are not always accurately set in the DMI
-table. For example my home server is a tower, but the DMI modalias
-claim it is a desktop.</p>
-
-<p><strong>SerIO subtype</strong></p>
-
-<p>This type is used for PS/2 mouse plugs. One example is from my
-test machine:</p>
-
-<p><blockquote>
-serio:ty01pr00id00ex00
-</blockquote></p>
-
-<p>The values present are</p>
-
-<pre>
- ty 01 (type)
- pr 00 (prototype)
- id 00 (id)
- ex 00 (extra)
-</pre>
-
-<p>This type is supported by the psmouse driver. I am not sure what
-the valid values are.</p>
-
-<p><strong>Other subtypes</strong></p>
-
-<p>There are heaps of other modalias subtypes according to
-file2alias.c. There is the rest of the list from that source: amba,
-ap, bcma, ccw, css, eisa, hid, i2c, ieee1394, input, ipack, isapnp,
-mdio, of, parisc, pcmcia, platform, scsi, sdio, spi, ssb, vio, virtio,
-vmbus, x86cpu and zorro. I did not spend time documenting all of
-these, as they do not seem relevant for my intended use with mapping
-hardware to packages when new stuff is inserted during run time.</p>
-
-<p><strong>Looking up kernel modules using modalias values</strong></p>
-
-<p>To check which kernel modules provide support for a given modalias,
-one can use the following shell script:</p>
-
-<pre>
- for id in $(find /sys -name modalias -print0 | xargs -0 cat | sort -u); do \
- echo "$id" ; \
- /sbin/modprobe --show-depends "$id"|sed 's/^/ /' ; \
- done
-</pre>
-
-<p>The output can look like this (only the first few entries as the
-list is very long on my test machine):</p>
-
-<pre>
- acpi:ACPI0003:
- insmod /lib/modules/2.6.32-5-686/kernel/drivers/acpi/ac.ko
- acpi:device:
- FATAL: Module acpi:device: not found.

+ <description><p>Earlier, I reported about
+<a href="http://people.skolelinux.org/pere/blog/How_to_fix_a_Thinkpad_X230_with_a_broken_180_GB_SSD_disk.html">my
+problems using an Intel SSD 520 Series 180 GB disk</a>. Friday I was
+told by IBM that the original disk should be thrown away. And as
+there no longer was a problem if I bricked the firmware, I decided
+today to try to install Intel firmware to replace the Lenovo firmware
+currently on the disk.</p>
+
+<p>I searched the Intel site for firmware, and found
+<a href="https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=3472&DwnldID=18363&ProductFamily=Solid-State+Drives+and+Caching&ProductLine=Intel%c2%ae+High+Performance+Solid-State+Drive&ProductProduct=Intel%c2%ae+SSD+520+Series+(180GB%2c+2.5in+SATA+6Gb%2fs%2c+25nm%2c+MLC)&lang=eng">issdfut_2.0.4.iso</a>
+(aka Intel SATA Solid-State Drive Firmware Update Tool) which
+according to the site should contain the latest firmware for SSD
+disks. I inserted the broken disk in one of my spare laptops and
+booted the ISO from a USB stick. The disk was recognized, but the
+program claimed the newest firmware already were installed and refused
+to insert any Intel firmware. So no change, and the disk is still
+unable to handle write load. :( I guess the only way to get them
+working would be if Lenovo releases new firmware. No idea how likely
+that is. Anyway, just blogging about this test for completeness. I
+got a working Samsung disk, and see no point in spending more time on
+the broken disks.</p>

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

+ <description><p>It has been a while since my last update. Since last summer, I
+have worked on a Norwegian
+<a href="http://www.docbook.org/">docbook</a> version of the 2004 book
+<a href="http://free-culture.cc/">Free Culture</a> by Lawrence Lessig,
+to get a Norwegian text explaining the problems with the copyright
+law. Yesterday, I finally broken the 90% mark, when counting the
+number of strings to translate. Due to real life constraints, I have
+not had time to work on it since March, but when the summer broke out,
+I found time to work on it again. Still lots of work left, but the
+first draft is nearing completion. I created a graph to show the
+progress of the translation:</p>
+
+<p><img width="80%" align="center" src="https://github.com/petterreinholdtsen/free-culture-lessig/raw/master/progress.png"></p>
+
+<p>When the first draft is done, the translated text need to be
+proof read, and the remaining formatting problems with images and SVG
+drawings need to be fixed. There are probably also some index entries
+missing that need to be added. This can be done by comparing the
+index entries listed in the SiSU version of the book, or comparing the
+English docbook version with the paper version. Last, the colophon
+page with ISBN numbers etc need to be wrapped up before the release is
+done. I should also figure out how to get correct Norwegian sorting
+of the index pages. All docbook tools I have tried so far (xmlto,
+docbook-xsl, dblatex) get the order of symbols and the special
+Norwegian letters ÆØÅ wrong.</p>
+
+<p>There is still need for translators and people with docbook
+knowledge, to be able to get a good looking book (I still struggle
+with dblatex, xmlto and docbook-xsl) as well as to do the draft
+translation and proof reading. And I would like the figures to be
+redrawn as SVGs to make it easy to translate them. Any SVG master
+around? There are also some legal terms that are unfamiliar to me.
+If you want to help, please get in touch with me, and check out the
+project files currently available from
+<a href="https://github.com/petterreinholdtsen/free-culture-lessig">github</a>.</p>
+
+<p>If you are curious what the translated book currently look like,
+the updated
+<a href="https://github.com/petterreinholdtsen/free-culture-lessig/blob/master/archive/freeculture.nb.pdf?raw=true">PDF</a>
+and
+<a href="https://github.com/petterreinholdtsen/free-culture-lessig/blob/master/archive/freeculture.nb.epub?raw=true">EPUB</a>
+are published on github. The HTML version is published as well, but
+github hand it out with MIME type text/plain, confusing browsers, so I
+saw no point in linking to that version.</p>

- <description><p>One thing that annoys me with Debian and Linux distributions in
-general, is that there is a great package management system with the
-ability to automatically install software packages by downloading them
-from the distribution mirrors, but no way to get it to automatically
-install the packages I need to use the hardware I plug into my
-machine. Even if the package to use it is easily available from the
-Linux distribution. When I plug in a LEGO Mindstorms NXT, it could
-suggest to automatically install the python-nxt, nbc and t2n packages
-I need to talk to it. When I plug in a Yubikey, it could propose the
-yubikey-personalization package. The information required to do this
-is available, but no-one have pulled all the pieces together.</p>
-
-<p>Some years ago, I proposed to
-<a href="http://lists.debian.org/debian-devel/2010/05/msg01206.html">use
-the discover subsystem to implement this</a>. The idea is fairly
-simple:

+ <description><p>The first wheezy based beta release of Debian Edu was wrapped up
+today. This is the release announcement:</p>
+
+<p><strong>New features for Debian Edu 7.1+edu0~b0 released
+2013-07-27</strong></p>
+
+<p>These are the release notes for for Debian Edu / Skolelinux
+7.1+edu0~b0, based on Debian with codename "Wheezy".</p>
+
+<p><strong>About Debian Edu and Skolelinux</strong></p>
+
+<p><a href="http://www.skolelinux.org/">Debian Edu, also known as
+Skolelinux</a>, is a Linux distribution based on Debian providing an
+out-of-the box environment of a completely configured school
+network. Immediately after installation a school server running all
+services needed for a school network is set up just waiting for users
+and machines being added via GOsa², a comfortable Web-UI. A netbooting
+environment is prepared using PXE, so after initial installation of
+the main server from CD, DVD or USB stick all other machines can be
+installed via the network. The provided school server provides LDAP
+database and Kerberos authentication service, centralized home
+directories, DHCP server, web proxy and many other services. The
+desktop contains
+<a href="http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html">more
+than 60 educational software packages</a> and more are available from
+the Debian archive, and schools can choose between KDE, Gnome, LXDE
+and Xfce desktop environment.</p>
+
+<p>This is the fifth test release based on Debian Wheezy. Basically
+this is an updated and slightly improved version compared to the
+Squeeze release.</p>
+
+<p>ALERT: Alpha based installations should reinstall or downgrade the
+versions of gosa and libpam-mklocaluser to the ones used in this beta
+release.</p>
+
+<p><strong>Software updates</strong></p>
<ul>
-<li>Add a desktop entry in /usr/share/autostart/ pointing to a program
- starting when a user log in.</li>
+<li>Switched roaming workstation profiles from wicd to network-manager
+ for network configuration, as wicd didn't work any more.</li>
+<li>Changed version numbers of patched gosa and libpam-mklocaluser
+ packages to make sure our locally patched versions will be replaced
+ by the official packages when they are released from Debian. Those
+ installing alpha version need to reinstall or manually downgrade gosa
+ and libpam-mklocaluser.</li>
+<li>Added bluetooth tools to the default desktop (bluedevil, blueman).</li>
+<li>Added tools for sharing the desktop on KDE (krdc, krfb).</li>
+<li>Added valgrind to the default installation for easier debugging of
+ crash bugs.</li>
+
+</ul>
-<li>Set this program up to listen for kernel events emitted when new
- hardware is inserted into the computer.</li>
+<p><strong>Other changes</strong></p>
-<li>When new hardware is inserted, look up the hardware ID in a
- database mapping to packages, and take note of any non-installed
- packages.</li>
+<ul>
-<li>Show a message to the user proposing to install the discovered
- package, and make it easy to install it.</li>
+<li>Fixed artwork package to work with gnome, no longer break
+ desktop=gnome installations.</li>
+<li>Adjusted installer to now work when forced to use a proxy with the
+ netinst CD.</li>
+<li>Fixed code detecting and setting/loading hardware specific
+ setup/firmware to work more robust out of the box.</li>
+<li>Adjusted Kerberos setup to detect realm and server settings at
+ install time instead of dynamically at run time. This avoid a crash
+ with krb5-auth-dialog on diskless workstations without a DNS name.</li>
+<li>Worked around misfeature in network-manager not calling the dhclient
+ exit hooks, causing automatic proxy configuration and automatic host
+ name setting at run time to work again.</li>
+<li>Fixed feature setting the default Iceweasel start page from URL
+ fetched from LDAP, to allow schools to set the global default by
+ updating the dc=skole,dc=skolelinux,dc=no LDAP object.</li>
+<li>Changed default host name on all networked machines to be unique
+ (generated from MAC or reverse DNS) after boot.</li>
+<li>Adjusted partition sizes to make sure they are big enough.</li>
</ul>
-<p>I am not sure what the best way to implement this is, but my
-initial idea was to use dbus events to discover new hardware, the
-discover database to find packages and
-<a href="http://www.packagekit.org/">PackageKit</a> to install
-packages.</p>
-
-<p>Yesterday, I found time to try to implement this idea, and the
-draft package is now checked into
-<a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">the
-Debian Edu subversion repository</a>. In the process, I updated the
-<a href="http://packages.qa.debian.org/d/discover-data.html">discover-data</a>
-package to map the USB ids of LEGO Mindstorms and Yubikey devices to
-the relevant packages in Debian, and uploaded a new version
-2.2013.01.09 to unstable. I also discovered that the current
-<a href="http://packages.qa.debian.org/d/discover.html">discover</a>
-package in Debian no longer discovered any USB devices, because
-/proc/bus/usb/devices is no longer present. I ported it to use
-libusb as a fall back option to get it working. The fixed package
-version 2.1.2-6 is now in experimental (didn't upload it to unstable
-because of the freeze).</p>
-
-<p>With this prototype in place, I can insert my Yubikey, and get this
-desktop notification to show up (only once, the first time it is
-inserted):</p>
-
-<p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2013-01-09-hw-autoinstall.png"></p>
-
-<p>For this prototype to be really useful, some way to automatically
-install the proposed packages by pressing the "Please install
-program(s)" button should to be implemented.</p>
-
-<p>If this idea seem useful to you, and you want to help make it
-happen, please help me update the discover-data database with mappings
-from hardware to Debian packages. Check if 'discover-pkginstall -l'
-list the package you would like to have installed when a given
-hardware device is inserted into your computer, and report bugs using
-reportbug if it isn't. Or, if you know of a better way to provide
-such mapping, please let me know.</p>
-
-<p>This prototype need more work, and there are several questions that
-should be considered before it is ready for production use. Is dbus
-the correct way to detect new hardware? At the moment I look for HAL
-dbus events on the system bus, because that is the events I could see
-on my Debian Squeeze KDE desktop. Are there better events to use?
-How should the user be notified? Is the desktop notification
-mechanism the best option, or should the background daemon raise a
-popup instead? How should packages be installed? When should they
-not be installed?</p>
-
-<p>If you want to help getting such feature implemented in Debian,
-please send me an email. :)</p>

+ <pubDate>Wed, 17 Jul 2013 23:50:00 +0200</pubDate>
+ <description><p>Today I switched to
+<a href="http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html">my
+new laptop</a>. I've previously written about the problems I had with
+my new Thinkpad X230, which was delivered with an
+<a href="http://people.skolelinux.org/pere/blog/Intel_SSD_520_Series_180_GB_with_Lenovo_firmware_still_lock_up_from_sustained_writes.html">180
+GB Intel SSD disk with Lenovo firmware</a> that did not handle
+sustained writes. My hardware supplier have been very forthcoming in
+trying to find a solution, and after first trying with another
+identical 180 GB disks they decided to send me a 256 GB Samsung SSD
+disk instead to fix it once and for all. The Samsung disk survived
+the installation of Debian with encrypted disks (filling the disk with
+random data during installation killed the first two), and I thus
+decided to trust it with my data. I have installed it as a Debian Edu
+Wheezy roaming workstation hooked up with my Debian Edu Squeeze main
+server at home using Kerberos and LDAP, and will use it as my work
+station from now on.</p>
+
+<p>As this is a solid state disk with no moving parts, I believe the
+Debian Wheezy default installation need to be tuned a bit to increase
+performance and increase life time of the disk. The Linux kernel and
+user space applications do not yet adjust automatically to such
+environment. To make it easier for my self, I created a draft Debian
+package <tt>ssd-setup</tt> to handle this tuning. The
+<a href="http://anonscm.debian.org/gitweb/?p=collab-maint/ssd-setup.git">source
+for the ssd-setup package</a> is available from collab-maint, and it
+is set up to adjust the setup of the machine by just installing the
+package. If there is any non-SSD disk in the machine, the package
+will refuse to install, as I did not try to write any logic to sort
+file systems in SSD and non-SSD file systems.</p>
+
+<p>I consider the package a draft, as I am a bit unsure how to best
+set up Debian Wheezy with an SSD. It is adjusted to my use case,
+where I set up the machine with one large encrypted partition (in
+addition to /boot), put LVM on top of this and set up partitions on
+top of this again. See the README file in the package source for the
+references I used to pick the settings. At the moment these
+parameters are tuned:</p>

-<p>Og et godt nytt år til dere alle!</p>
+<p>During installation, I cancelled the part where the installer fill
+the disk with random data, as this would kill the SSD performance for
+little gain. My goal with the encrypted file system is to ensure
+those stealing my laptop end up with a brick and not a working
+computer. I have no hope in keeping the really resourceful people
+from getting the data on the disk (see
+<a href="http://xkcd.com/538/">XKCD #538</a> for an explanation why).
+Thus I concluded that adding the discard option to crypttab is the
+right thing to do.</p>
+
+<p>I considered using the noop I/O scheduler, as several recommended
+it for SSD, but others recommended deadline and a benchmark I found
+indicated that deadline might be better for interactive use.</p>
+
+<p>I also considered using the 'discard' file system option for ext3
+and ext4, but read that it would give a performance hit ever time a
+file is removed, and thought it best to that that slowdown once a day
+instead of during my work.</p>
+
+<p>My package do not set up tmpfs on /var/run, /var/lock and /tmp, as
+this is already done by Debian Edu.</p>
+
+<p>I have not yet started on the user space tuning. I expect
+iceweasel need some tuning, and perhaps other applications too, but
+have not yet had time to investigate those parts.</p>
+
+<p>The package should work on Ubuntu too, but I have not yet tested it
+there.</p>
+
+<p>As for the answer to the question in the title of this blog post,
+as far as I know, the only solution I know about is to replace the
+disk. It might be possible to flash it with Intel firmware instead of
+the Lenovo firmware. But I have not tried and did not want to do so
+without approval from Lenovo as I wanted to keep the warranty on the
+disk until a solution was found and they wanted the broken disks
+back.</p>

+ <description><p>A few days ago, I wrote about
+<a href="http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html">the
+problems I experienced with my new X230 and its SSD disk</a>, which
+was dying during installation because it is unable to cope with
+sustained write. My supplier is in contact with
+<a href="http://www.lenovo.com/">Lenovo</a>, and they wanted to send a
+replacement disk to try to fix the problem. They decided to send an
+identical model, so my hopes for a permanent fix was slim.</p>
+
+<p>Anyway, today I got the replacement disk and tried to install
+Debian Edu Wheezy with encrypted disk on it. The new disk have the
+same firmware version as the original. This time my hope raised
+slightly as the installation progressed, as the original disk used to
+die after 4-7% of the disk was written to, while this time it kept
+going past 10%, 20%, 40% and even past 50%. But around 60%, the disk
+died again and I was back on square one. I still do not have a new
+laptop with a disk I can trust. I can not live with a disk that might
+lock up when I download a new
+<a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a> ISO or
+other large files. I look forward to hearing from my supplier with
+the next proposal from Lenovo.</p>
+
+<p>The original disk is marked Intel SSD 520 Series 180 GB,
+11S0C38722Z1ZNME35X1TR, ISN: CVCV321407HB180EGN, SA: G57560302, FW:

+ <description><p>Half a year ago, I reported that I had to find a
+<a href="http://people.skolelinux.org/pere/blog/Thank_you_Thinkpad_X41__for_your_long_and_trustworthy_service.html">replacement
+for my trusty old Thinkpad X41</a>. Unfortunately I did not have much
+time to spend on it, and it took a while to find a model I believe
+will do the job, but two days ago the replacement finally arrived. I
+ended up picking a
+<a href="http://www.linlap.com/lenovo_thinkpad_x230">Thinkpad X230</a>
+with SSD disk (NZDAJMN). I first test installed Debian Edu Wheezy as
+a roaming workstation, and it seemed to work flawlessly. But my
+second installation with encrypted disk was not as successful. More
+on that below.</p>
+
+<p>I had a hard time trying to track down a good laptop, as my most
+important requirements (robust and with a good keyboard) are never
+listed in the feature list. But I did get good help from the search
+feature at <a href="http://www.prisjakt.no/">Prisjakt</a>, which
+allowed me to limit the list of interesting laptops based on my other
+requirements. A bit surprising that SSD disk are not disks according
+to that search interface, so I had to drop specifying the number of
+disks from my search parameters. I also asked around among friends to
+get their impression on keyboards and robustness.</p>
+
+<p>So the new laptop arrived, and it is quite a lot wider than the
+X41. I am not quite convinced about the keyboard, as it is
+significantly wider than my old keyboard, and I have to stretch my
+hand a lot more to reach the edges. But the key response is fairly
+good and the individual key shape is fairly easy to handle, so I hope
+I will get used to it. My old X40 was starting to fail, and I really
+needed a new laptop now. :)</p>
+
+<p>Turning off the touch pad was simple. All it took was a quick
+visit to the BIOS during boot it disable it.</p>
+
+<p>But there is a fatal problem with the laptop. The 180 GB SSD disk
+lock up during load. And this happen when installing Debian Wheezy
+with encrypted disk, while the disk is being filled with random data.
+I also tested to install Ubuntu Raring, and it happen there too if I
+reenable the code to fill the disk with random data (it is disabled by
+default in Ubuntu). And the bug with is already known. It was
+reported to Debian as <a href="http://bugs.debian.org/691427">BTS
+report #691427 2012-10-25</a> (journal commit I/O error on brand-new
+Thinkpad T430s ext4 on lvm on SSD). It is also reported to the Linux
+kernel developers as
+<a href="https://bugzilla.kernel.org/show_bug.cgi?id=51861">Kernel bugzilla
+report #51861 2012-12-20</a> (Intel SSD 520 stops working under load
+(SSDSC2BW180A3L in Lenovo ThinkPad T430s)). It is also reported on the
+Lenovo forums, both for
+<a href="http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T430s-Intel-SSD-520-180GB-issue/m-p/1070549">T430
+2012-11-10</a> and for
+<a href="http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/x230-SATA-errors-with-180GB-Intel-520-SSD-under-heavy-write-load/m-p/1068147">X230
+03-20-2013</a>. The problem do not only affect installation. The
+reports state that the disk lock up during use if many writes are done
+on the disk, so it is much no use to work around the installation
+problem and end up with a computer that can lock up at any moment.
+There is even a
+<a href="https://git.efficios.com/?p=test-ssd.git">small C program
+available</a> that will lock up the hard drive after running a few
+minutes by writing to a file.</p>
+
+<p>I've contacted my supplier and asked how to handle this, and after
+contacting PCHELP Norway (request 01D1FDP) which handle support
+requests for Lenovo, his first suggestion was to upgrade the disk
+firmware. Unfortunately there is no newer firmware available from
+Lenovo, as my disk already have the most recent one (version LF1i). I
+hope to hear more from him today and hope the problem can be
+fixed. :)</p>
