- <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>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>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>
-
-<p><strong>Other changes</strong></p>
-
-<ul>
-
-<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><strong>Known issues</strong></p>
-
-<ul>
-
-<li>Grub is missing the new artwork.</li>
-<li>KDE fail to understand the wpad.dat file provided, causing it to
- not use the http proxy as it should.</li>
-<li>Chromium also fail to use the proxy.</li>

- <title>How to fix a Thinkpad X230 with a broken 180 GB SSD disk</title>
- <link>http://people.skolelinux.org/pere/blog/How_to_fix_a_Thinkpad_X230_with_a_broken_180_GB_SSD_disk.html</link>
- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/How_to_fix_a_Thinkpad_X230_with_a_broken_180_GB_SSD_disk.html</guid>
- <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>
-
-<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>

- <title>Intel SSD 520 Series 180 GB with Lenovo firmware still lock up from sustained writes</title>

- <pubDate>Wed, 10 Jul 2013 13:30:00 +0200</pubDate>
- <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,
