-bitcoin related blog post</a> mentioned that the new
-<a href="http://packages.qa.debian.org/bitcoin">bitcoin package</a> for
-Debian was waiting in NEW. It was accepted by the Debian ftp-masters
-2013-01-19, and have been available in unstable since then. It was
-automatically copied to Ubuntu, and is available in their Raring
-version too.</p>
-
-<p>But there is a strange problem with the build that block this new
-version from being available on the i386 and kfreebsd-i386
-architectures. For some strange reason, the autobuilders in Debian
-for these architectures fail to run the test suite on these
-architectures (<a href="http://bugs.debian.org/672524">BTS #672524</a>).
-We are so far unable to reproduce it when building it manually, and

-<p>One feature that is annoying me with of the bitcoin client, because
-I often run low on disk space, is the fact that the client will exit

+ <div class="date">22nd August 2013</div>
+ <div class="body"><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>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><strong>Other changes</strong></p>
+
+<ul>
+
+<li>Adjusted the USB stick ISO image build to include every tool
+needed for desktop=xfce installations.</li>
+<li>Adjust thin-client-server task to work when installing from USB
+stick ISO image.</li>
+<li>Made new grub artwork (changed png from indexed to RGB format).</li>
+<li>Minor cleanup in the CUPS setup.</li>
+<li>Make sure that bootstrapping of the Samba domain really happens
+ during installation of the main server and adjust SID handling to
+ cope with this.</li>
+<li>Make Samba passwords changeable (again) via GOsa².</li>
+<li>Fix generation of LM and NT password hashes via GOsa² to avoid
+ empty password hashes.</li>
+<li>Adapted Samba machine domain joining to latest change in the
+ smbldap-tools Perl package, fixing bugs blocking Windows machines
+ from joining the Samba domain.</li>
+
+</ul>
+
+<p><strong>Known issues</strong></p>
+
+<ul>
+
+<li>KDE fails to understand the wpad.dat file provided, causing it to
+ not use the http proxy as it should.</li>
+<li>Chromium also fails to use the proxy when using the KDE desktop
+ (using the KDE configuration).</li>

- <div class="date">22nd January 2013</div>
- <div class="body"><p>Yesterday, I
-<a href="http://people.skolelinux.org/pere/blog/First_prototype_ready_making_hardware_easier_to_use_in_Debian.html">asked
-for testers</a> for my prototype for making Debian better at handling
-pluggable hardware devices, which I
-<a href="http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">set
-out to create</a> earlier this month. Several valuable testers showed
-up, and caused me to really want to to open up the development to more
-people. But before I did this, I want to come up with a sensible name
-for this project. Today I finally decided on a new name, and I have
-renamed the project from hw-support-handler to this new name. In the
-process, I moved the source to git and made it available as a
-<a href="http://anonscm.debian.org/gitweb/?p=collab-maint/isenkram.git">collab-maint</a>
-repository in Debian. The new name? It is <strong>Isenkram</strong>.
-To fetch and build the latest version of the source, use</p>
-
-<pre>
-git clone http://anonscm.debian.org/git/collab-maint/isenkram.git
-cd isenkram && git-buildpackage -us -uc
-</pre>
-
-<p>I have not yet adjusted all files to use the new name yet. If you
-want to hack on the source or improve the package, please go ahead.
-But please talk to me first on IRC or via email before you do major
-changes, to make sure we do not step on each others toes. :)</p>
-
-<p>If you wonder what 'isenkram' is, it is a Norwegian word for iron
-stuff, typically meaning tools, nails, screws, etc. Typical hardware
-stuff, in other words. I've been told it is the Norwegian variant of
-the German word eisenkram, for those that are familiar with that
-word.</p>
-
-<p><strong>Update 2013-01-26</strong>: Added -us -us to build
-instructions, to avoid confusing people with an error from the signing
-process.</p>
-
-<p><strong>Update 2013-01-27</strong>: Switch to HTTP URL for the git
-clone argument to avoid the need for authentication.</p>

+ <div class="date">18th August 2013</div>
+ <div class="body"><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>

- <div class="title"><a href="http://people.skolelinux.org/pere/blog/First_prototype_ready_making_hardware_easier_to_use_in_Debian.html">First prototype ready making hardware easier to use in Debian</a></div>
- <div class="date">21st January 2013</div>
- <div class="body"><p>Early this month I set out to try to
-<a href="http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">improve
-the Debian support for pluggable hardware devices</a>. Now my
-prototype is working, and it is ready for a larger audience. To test
-it, fetch the
-<a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">source
-from the Debian Edu subversion repository</a>, build and install the
-package. You might have to log out and in again activate the
-autostart script.</p>
-
-<p>The design is simple:</p>
-
-<ul>
-
-<li>Add desktop entry in /usr/share/autostart/ causing a program
-hw-support-handlerd to start when the user log in.</li>
-
-<li>This program listen for kernel events about new hardware (directly
-from the kernel like udev does), not using HAL dbus events as I
-initially did.</li>
-
-<li>When new hardware is inserted, look up the hardware modalias in
-the APT database, a database
-<a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=markup">available
-via HTTP</a> and a database available as part of the package.</li>
-
-<li>If a package is mapped to the hardware in question, the package
-isn't installed yet and this is the first time the hardware was
-plugged in, show a desktop notification suggesting to install the
-package or packages.</li>
-
-<li>If the user click on the 'install package now' button, ask
-aptdaemon via the PackageKit API to install the requrired package.</li>
-
-<li>aptdaemon ask for root password or sudo password, and install the
-package while showing progress information in a window.</li>
-
-</ul>
-
-<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><img src="http://people.skolelinux.org/pere/blog/images/2013-01-21-hw-support-1-notification.png">
-<br><img src="http://people.skolelinux.org/pere/blog/images/2013-01-21-hw-support-2-password.png">
-<br><img src="http://people.skolelinux.org/pere/blog/images/2013-01-21-hw-support-3-dependencies.png">

-<br><img src="http://people.skolelinux.org/pere/blog/images/2013-01-21-hw-support-5-installing-details.png" width="70%"></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>
-
-<p><strong>Update 2013-01-23 12:00</strong>: The project is now
-renamed to Isenkram and the source moved from the Debian Edu
-subversion repository to a Debian collab-maint git repository. See
-<a href="http://people.skolelinux.org/pere/blog/Welcome_to_the_world__Isenkram_.html">build
-instructions</a> for details.</p>

+ <div class="date"> 2nd August 2013</div>
+ <div class="body"><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>

-<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

- <div class="date">18th January 2013</div>
- <div class="body"><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>

+ <div class="date">17th July 2013</div>
+ <div class="body"><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>
+
+<ul>
+
+<li>Set up cryptsetup to pass TRIM commands to the physical disk
+ (adding discard to /etc/crypttab)</li>
+
+<li>Set up LVM to pass on TRIM commands to the underlying device (in
+ this case a cryptsetup partition) by changing issue_discards from
+ 0 to 1 in /etc/lvm/lvm.conf.</li>
+
+<li>Set relatime as a file system option for ext3 and ext4 file
+ systems.</li>
+
+<li>Tell swap to use TRIM commands by adding 'discard' to
+ /etc/fstab.</li>
+
+<li>Change I/O scheduler from cfq to deadline using a udev rule.</li>
+
+<li>Run fstrim on every ext3 and ext4 file system every night (from
+ cron.daily).</li>
+
+<li>Adjust sysctl values vm.swappiness to 1 and vm.vfs_cache_pressure
+ to 50 to reduce the kernel eagerness to swap out processes.</li>
+
+</ul>
+
+<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>

- <div class="date">15th January 2013</div>
- <div class="body"><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

- <div class="date">14th January 2013</div>
- <div class="body"><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
-<URL: <a href="https://wiki.archlinux.org/index.php/Modalias">https://wiki.archlinux.org/index.php/Modalias</a> >,
-<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> >,
-<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> > and
-<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> >.
-
-<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:

+ <div class="date"> 5th July 2013</div>
+ <div class="body"><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>

+today. This is the release announcement:</p>
+
+<p><strong>New features for Debian Edu 7.1+edu0~alpha3 released
+2013-07-03</strong></p>
+
+<p>These are the release notes for for Debian Edu / Skolelinux
+7.1+edu0~alpha3, 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 fourth test release based on Debian Wheezy. Basically
+this is an updated and slightly improved version compared to the
+Squeeze release.</p>
+
+<p><strong>Software updates</strong></p>
+<ul>
+ <li>Dropped ispell dictionaries from our default installation.</li>
+ <li>Dropped menu-xdg from the KDE desktop option, to drop the Debian
+ submenu. It was not included with Gnome, LXDE or Xfce, so this
+ brings KDE in line with the others.</li>
+ <li>Dropped xdrawchem, xjig and xsok from our default installation as
+ they don't have a desktop menu entry and thus won't show up in the
+ menu now that menu-xdg was removed.</li>
+ <li>Removed the killer system to kill left behind processes on
+ multi-user machines, as it was no longer able to understand when a
+ X display was in use and killed the processes of the active users
+ too.</li>
+ <li>Dropped the golearn (from goplay) package as the debtags in wheezy
+ are too few to make the package useful.</li>
+</ul>
+<p><strong>Other changes</strong></p>
<ul>

+<p><strong>How to report bugs</strong></p>
-<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>
