+ <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>

+<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">27th May 2013</div>
- <div class="body"><p>Two days ago, I asked
-<a href="http://people.skolelinux.org/pere/blog/How_can_I_install_Linux_on_a_Packard_Bell_Easynote_LV_preinstalled_with_Windows_8_.html">how
-I could install Linux on a Packard Bell EasyNote LV computer
-preinstalled with Windows 8</a>. I found a solution, but am horrified
-with the obstacles put in the way of Linux users on a laptop with UEFI
-and Windows 8.</p>
-
-<p>I never found out if the cause of my problems were the use of UEFI
-secure booting or fast boot. I suspect fast boot was the problem,
-causing the firmware to boot directly from HD without considering any
-key presses and alternative devices, but do not know UEFI settings
-enough to tell.</p>
-
-<p>There is no way to install Linux on the machine in question without
-opening the box and disconnecting the hard drive! This is as far as I
-can tell, the only way to get access to the firmware setup menu
-without accepting the Windows 8 license agreement. I am told (and
-found description on how to) that it is possible to configure the
-firmware setup once booted into Windows 8. But as I believe the terms
-of that agreement are completely unacceptable, accepting the license
-was never an alternative. I do not enter agreements I do not intend
-to follow.</p>
-
-<p>I feared I had to return the laptops and ask for a refund, and
-waste many hours on this, but luckily there was a way to get it to
-work. But I would not recommend it to anyone planning to run Linux on
-it, and I have become sceptical to Windows 8 certified laptops. Is
-this the way Linux will be forced out of the market place, by making
-it close to impossible for "normal" users to install Linux without
-accepting the Microsoft Windows license terms? Or at least not
-without risking to loose the warranty?</p>
-
-<p>I've updated the
-<a href="http://www.linlap.com/packard_bell_easynote_lv">Linux Laptop
-wiki page for Packard Bell EasyNote LV</a>, to ensure the next person
-do not have to struggle as much as I did to get Linux into the
-machine.</p>

+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

- <div class="body"><p>I've run into quite a problem the last few days. I bought three
-new laptops for my parents and a few others. I bought Packard Bell
-Easynote LV to run Kubuntu on and use as their home computer. But I
-am completely unable to figure out how to install Linux on it. The
-computer is preinstalled with Windows 8, and I suspect it uses UEFI
-instead of a BIOS to boot.</p>
-
-<p>The problem is that I am unable to get it to PXE boot, and unable
-to get it to boot the Linux installer from my USB stick. I have yet
-to try the DVD install, and still hope it will work. when I turn on
-the computer, there is no information on what buttons to press to get
-the normal boot menu. I expect to get some boot menu to select PXE or
-USB stick booting. When booting, it first ask for the language to
-use, then for some regional settings, and finally if I will accept the
-Windows 8 terms of use. As these terms are completely unacceptable to
-me, I have no other choice but to turn off the computer and try again
-to get it to boot the Linux installer.</p>
-
-<p>I have gathered my findings so far on a Linlap page about the
-<a href="http://www.linlap.com/packard_bell_easynote_lv">Packard Bell
-EasyNote LV</a> model. If you have any idea how to get Linux
-installed on this machine, please get in touch or update that wiki
-page. If I can't find a way to install Linux, I will have to return
-the laptop to the seller and find another machine for my parents.</p>
-
-<p>I wonder, is this the way Linux will be forced out of the market
-using UEFI and "secure boot" by making it impossible to install Linux
-on new Laptops?</p>

- <div class="date">24th May 2013</div>
- <div class="body"><p>En ting
-<a href="http://www.skolelinux.org/">Skolelinux-prosjektet</a> har
-hatt mye glede av er studentprosjekter. F.eks. er
-<a href="http://linuxstopmotion.org/">stillbildeanimasjonssystemet
-Stopmotion</a> resultat av et studentprosjekt i Skolelinux. De siste
-månedene har en ivrig student veiledet av Marius Kotsbak i
-<a href="http://www.friprogramvareiskolen.no/">FRiSK</a> testet hva en
-kan få til med en datamaskin til NOK 400,- (antagelig 1700,- med
-skjerm, tastatur og mus) når det brukes i Skolelinux. Jeg spurte han
-om et intervju.</p>
-
-<p><strong>Hvem er du, og hva driver du med til daglig?</strong></p>
-
-<p>Jeg heter Nirosan Thiyagalingam. Jeg er 24 år og studerer
-dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for
-data har siden ung alder vært tilstede og jeg har i tillegg alltid
-vært glad i å lære nye ting. Med teknologi som endres svært hurtig er
-det alltid noe nytt å lære. Noe som igjen har gjort det svært
-interessant å følge med på utviklingen. Jeg valgte dataingeniør
-studiet grunnet ønske om å lære enda mer om programmering og utvikling
-av store systemer.</p>
-
-<p><strong>Hvordan kom du i kontakt med Skolelinux-prosjektet?</strong></p>
-
-<p>Skolelinux prosjektet hørte jeg først om i media. Men det var først
-når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for
-prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine
-hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og
-jeg valgte derfor en oppgave som gikk ut på å få en
-<a href="http://www.raspberrypi.org">Raspberry PI</a>. Altså en
-ultra-billig datamaskin til å kjøre Debian Edu på lik linje med
-vanlige datamaskiner. I løpet av prosjektet ble det gjort mye
-forskning på nettet. Det var mye jeg måtte forstå rundt hvordan
-operativsystemet Linux fungerte før jeg kunne angripe
-problemet. Prøvde først å finne ut hvordan man kunne transformere en
-vanlig installasjon av Skolelinux til Raspberry PI, men dette var
-altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble
-videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk
-diskutert hvilken retning jeg burde gå for å få til en fullverdig
-løsning. Det ble bestemt at jeg skulle gå for å først installere
-<a href="http://www.raspbian.org/">Raspian</a>. Dette er et
-operativsystem basert på Debian spesiallaget for Raspberry Pi sin
-maskinvare. Nå som Debian var installert på datamaskinen gjenstod det
-å installere de nødvendige Skolelinux pakkene for å få til et
-fullverdig system. Disse pakkene ble installert manuelt i første
-omgang, men ble senere installert automatisk via et script som Petter
-Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i
-gang med installasjonen i løpet av bare 5 minutter. Ikke nok med det,
-alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med
-resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak
-maskin og det merkes godt når man har installert Skolelinux på
-den. Video og 3D-rendering fungerer utrolig dårlig, men nettsurfing og
-kontorprogrammer fungerer godt. Det kan derfor konkluderes med at
-datamaskinen er egnet for enkle oppgaver.
-
-<p>Jeg syns det er viktig påpeke at dette kun er startfasen av en slik
-løsning. På markedet finnes det nå maskiner som har bedre hardware enn
-Raspberry Pi. Det er store muligheter for at man kan klare å
-installere Skolelinux på disse også, og da forsvinner nok mest
-sannsynlig ytelsesproblemene med Video og 3D rendering også.</p>
-
-<p>Det ble også prøvd med en løsning som gjorde at Raspberry Pi
-fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse
-med tanke på hastighet og brukeropplevelse. Men også her var video og
-3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt
-<a href="http://www.berryterminal.com/">BerryTerminal</a> for å få til
-dette.</p>
-
-<p><strong>Hva er fordelene med Skolelinux slik du ser det?</strong></p>
-
-<p>Fordelen med Skolelinux er mange. At det er gratis er en stor
-fordel, men at det er så mange som er med på å utvikle det og
-vedlikeholde det er en enda større fordel. Allerede før jeg startet
-med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen
-så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet
-hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de
-nødvendige programmene og funksjonen som både små og store skoler i
-tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en
-så komplett løsning er en kjempefordel. Installasjonen er knirkefri
-og det er svært enkelt å installere og komme i gang.</p>
-
-<p><strong>Hva er ulempene med Skolelinux slik du ser det?</strong></p>
-
-<p>Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv
-om websidene er enkle og konsise er det allikevel ikke appellerende i
-like stor grad som for eksempel
-<a href="http://www.ubuntu.com">Ubuntu</a> sine sider. Deres side
-tilbyr, i tillegg til godt design og presentasjon, en nettbasert
-emulator av deres operativsystem. Dette er en stor fordel slik jeg ser
-det. Bortsett fra dette ser jeg absolutt ingen ulemper med
-Skolelinux-prosjektet.</p>
-
-<p><strong>Hvilken fri programvare bruker du til daglig?</strong></p>
-
-<p>Til daglig er jeg en flittig bruker av det åpne media
-sentersystemet <a href="http://xbmc.org/">XBMC</a>. Det enorme
-samfunnet rundt dette prosjektet har gjort dette til et program som
-dekker alles behov. Man kan tilpasse det akkurat slik man vil både med
-tanke på utseende og funksjoner ved installere plug-ins eller
-scripts.</p>
-
-<p><strong>Hvilken strategi tror du er den rette å bruke for å få
-skoler til å ta i bruk fri programvare?</strong></p>
-
-<p>Strategien som burde brukes sett fra mine øyne er
-markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn
-i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe
-annet som koster de store summer. At skolelinux til de grader tilbyr
-en så komplett løsning bure komme frem. Enten via reklamekampanjer
-eller ved å sende ut folk til skoler for så å la skolenettverk
-ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det
-i tillegg ble utviklet gode websider og en emulator for å la brukere
-prøve operativsystemet ville nok dette ha styrket inntrykket
-betraktelig.</p>

+ <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>

- <div class="date">17th May 2013</div>
- <div class="body"><p><a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a> is
-an operating system based on Debian intended for use in schools. It
-contain a turn-key solution for the computer network provided to
-pupils in the primary schools. It provide both the central server,
-network boot servers and desktop environments with heaps of
-educational software. The project was founded almost 12 years ago,
-2001-07-02. If you want to support the project, which is in need for
-cash to fund developer gatherings and other project related activity,
-<a href="http://www.linuxiskolen.no/slxdebianlabs/donations.html">please
-donate some money</a>.
-
-<p>A topic that come up again and again on the Debian Edu mailing
-lists and elsewhere, is the question on how to transform a Debian or
-Ubuntu installation into a Debian Edu installation. It isn't very
-hard, and last week I wrote a script to replicate the steps done by
-the Debian Edu installer.</p>
-
-<p>The script,
-<a href="http://anonscm.debian.org/viewvc/debian-edu/branches/wheezy/debian-edu-config/share/debian-edu-config/tools/debian-edu-bless?view=markup">debian-edu-bless<a/>
-in the debian-edu-config package, will go through these six steps and
-transform an existing Debian Wheezy or Ubuntu (untested) installation
-into a Debian Edu Workstation:</p>
-
-<ol>
-
-<li>Add skolelinux related APT sources.</li>
-<li>Create /etc/debian-edu/config with the wanted configuration.</li>
-<li>Install debian-edu-install to load preseeding values and pull in
- our configuration.</li>
-<li>Preseed debconf database with profile setup in
- /etc/debian-edu/config, and run tasksel to install packages
- according to the profile specified in the config above,
- overriding some of the Debian automation machinery.</li>
-<li>Run debian-edu-cfengine-D installation to configure everything
- that could not be done using preseeding.</li>
-<li>Ask for a reboot to enable all the configuration changes.</li>
-
-</ol>
-
-<p>There are some steps in the Debian Edu installation that can not be
-replicated like this. Disk partitioning and LVM setup, for example.
-So this script just assume there is enough disk space to install all
-the needed packages.</p>
-
-<p>The script was created to help a Debian Edu student working on
-setting up <a href="http://www.raspberrypi.org">Raspberry Pi</a> as a
-Debian Edu client, and using it he can take the existing
-<a href="http://www.raspbian.org/FrontPage">Raspbian</a> installation and
-transform it into a fully functioning Debian Edu Workstation (or
-Roaming Workstation, or whatever :).</p>
-
-<p>The default setting in the script is to create a KDE Workstation.
-If a LXDE based Roaming workstation is wanted instead, modify the
-PROFILE and DESKTOP values at the top to look like this instead:</p>
-
-<p><pre>
-PROFILE="Roaming-Workstation"
-DESKTOP="lxde"
-</pre></p>
-
-<p>The script could even become useful to set up Debian Edu servers in
-the cloud, by starting with a virtual Debian installation at some

+ <div class="body"><p>Half a year ago, I reported that I had to find a replacement for my
+trusty old Thinkpad X41. Unfortunately I did not have much time to
+spend on it, but today 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 worked flawlessly. As I write
+this, it is installing what I hope will be a more final installation,
+with a encrypted hard drive to ensure any dope head stealing it end up
+with an expencive door stop.</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 <ahref="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, so I had
+to drop number of disks from my search parameters.</p>
+
+<p>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>I look forward to figuring out how to turn off the touch pad.</p>

<p><strong>About Debian Edu and Skolelinux</strong></p>
-<p>Debian Edu, also known as Skolelinux, is a Linux distribution based
-on Debian providing an out-of-the box environment of a completely
-configured school network. Immediatly 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.</p>
-
-<p>This is the first test release based on Wheezy (which currently is
-not released yet). Basically this is an updated and slightly improved
-version compared to the Squeeze release.</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>Install freemind (0.9.0) by default, and stop installing vym by
- default.</li>
- <li>Install chromium (26.0.1410.43) by default.</li>
- <li>Install goplay (0.5-1.1) to make golearn available by default.</li>

- ibus-anthy.</li>
+ <li>Dropped ispell dictionaries from our default installation.</li>
+ <li>Dropped menu-xdg from the KDE desktop option, to drop the Debian

+ 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>

+ <li>Fixed proxy configuration on Main Server installations.</li>
+ <li>Changed LTSP setup to ask dpkg to use force-unsafe-io the same way
+ d-i is doing it.</li>
+ <li>Made sure root and user passwords were not left behind in the
+ debconf database after installation on Main Server installations.</li>
+ <li>Made Roaming Workstation dynamic setup more robust and added draft
+ script setup-ad-client to hook a Roaming Workstation up to a
+ Active Directory server instead of a Debian Edu Main Server.</li>
+ <li>Update system to install needed firmware packages during
+ installation, to work properly in Wheezy.</li>

+ <div class="title"><a href="http://people.skolelinux.org/pere/blog/Automatically_locate_and_install_required_firmware_packages_on_Debian__Isenkram_0_4_.html">Automatically locate and install required firmware packages on Debian (Isenkram 0.4)</a></div>
+ <div class="date">25th June 2013</div>
+ <div class="body"><p>It annoys me when the computer fail to do automatically what it is
+perfectly capable of, and I have to do it manually to get things
+working. One such task is to find out what firmware packages are
+needed to get the hardware on my computer working. Most often this
+affect the wifi card, but some times it even affect the RAID
+controller or the ethernet card. Today I pushed version 0.4 of the
+<a href="http://packages.qa.debian.org/isenkram">Isenkram package</a>
+including a new script isenkram-autoinstall-firmware handling the
+process of asking all the loaded kernel modules what firmware files
+they want, find debian packages providing these files and install the
+debian packages. Here is a test run on my laptop:</p>
+
+<p><pre>
+# isenkram-autoinstall-firmware
+info: kernel drivers requested extra firmware: ipw2200-bss.fw ipw2200-ibss.fw ipw2200-sniffer.fw
+info: fetching http://http.debian.net/debian/dists/squeeze/Contents-i386.gz
+info: locating packages with the requested firmware files
+info: Updating APT sources after adding non-free APT source
+info: trying to install firmware-ipw2x00
+firmware-ipw2x00
+firmware-ipw2x00
+Preconfiguring packages ...
+Selecting previously deselected package firmware-ipw2x00.
+(Reading database ... 259727 files and directories currently installed.)
+Unpacking firmware-ipw2x00 (from .../firmware-ipw2x00_0.28+squeeze1_all.deb) ...
+Setting up firmware-ipw2x00 (0.28+squeeze1) ...
+#
+</pre></p>
+
+<p>When all the requested firmware is present, a simple message is
+printed instead:</p>
+
+<p><pre>
+# isenkram-autoinstall-firmware
+info: did not find any firmware files requested by loaded kernel modules. exiting
+#
+</pre></p>
+
+<p>It could use some polish, but it is already working well and saving
+me some time when setting up new machines. :)</p>
+
+<p>So, how does it work? It look at the set of currently loaded
+kernel modules, and look up each one of them using modinfo, to find
+the firmware files listed in the module meta-information. Next, it
+download the Contents file from a nearby APT mirror, and search for
+the firmware files in this file to locate the package with the
+requested firmware file. If the package is in the non-free section, a
+non-free APT source is added and the package is installed using
+<tt>apt-get install</tt>. The end result is a slightly better working
+machine.</p>
+
+<p>I hope someone find time to implement a more polished version of
+this script as part of the hw-detect debian-installer module, to
+finally fix <a href="http://bugs.debian.org/655507">BTS report
+#655507</a>. There really is no need to insert USB sticks with
+firmware during a PXE install when the packages already are available
+from the nearby Debian mirror.</p>

+ <div class="date">22nd June 2013</div>
+ <div class="body"><p>In the <a href="http://www.skolelinux.org/">Debian Edu /
+Skolelinux</a> project, we include a post-installation test suite,
+which check that services are running, working, and return the
+expected results. It runs automatically just after the first boot on
+test installations (using test ISOs), but not on production
+installations (using non-test ISOs). It test that the LDAP service is
+operating, Kerberos is responding, DNS is replying, file systems are
+online resizable, etc, etc. And it check that the PXE service is
+configured, which is the topic of this post.</p>
+
+<p>The last week I've fixed the DVD and USB stick ISOs for our Debian
+Edu Wheezy release. These ISOs are supposed to be able to install a
+complete system without any Internet connection, but for that to
+happen all the needed packages need to be on them. Thanks to our test
+suite, I discovered that we had forgotten to adjust our PXE setup to
+cope with the new names and paths used by the netboot d-i packages.
+When Internet connectivity was available, the installer fall back to
+using wget to fetch d-i boot images, but when offline it require
+working packages to get it working. And ad the packages changed name
+from debian-installer-6.0-netboot-$arch to
+debian-installer-7.0-netboot-$arch, we no longer pulled in the
+packages during installation. Without our test suite, I suspect we
+would never have discovered this before release. Now it is fixed
+right after we got the ISOs operational.</p>
+
+<p>Another by-product of the test suite is that we can ask system
+administrators with problems getting Debian Edu to work, to run the
+test suite using <tt>/usr/sbin/debian-edu-test-install</tt> and see if
+any errors are detected. This usually pinpoint the subsystem causing
+the problem.</p>

-<a href="http://www.debian.org/News/2013/20130504">release announcement
-for Debian Wheezy</a> was waiting in my mail box. This is a great
-Debian release, and I expect to move my machines at home over to it fairly
-soon.</p>
-
-<p>The new debian release contain heaps of new stuff, and one program
-in particular make me very happy to see included. The
-<a href="http://scratch.mit.edu/">Scratch</a> program, made famous by
-the <a href="http://www.code.org/">Teach kids code</a> movement, is
-included for the first time. Alongside similar programs like
-<a href="http://edu.kde.org/kturtle/">kturtle</a> and
-<a href="http://wiki.sugarlabs.org/go/Activities/Turtle_Art">turtleart</a>,
-it allow for visual programming where syntax errors can not happen,
-and a friendly programming environment for learning to control the
-computer. Scratch will also be included in the next release of Debian
-Edu.</a>
-

+ <div class="date">17th June 2013</div>
+ <div class="body"><p>The <a href="http://www.skolelinux.org/">Debian Edu and
+Skolelinux</a> distribution have users and contributors all around the
+globe. And a while back, an enterprising young man showed up on
+<a href="irc://irc.debian.org/%23debian-edu">our IRC channel
+#debian-edu</a> and started asking questions about how Debian Edu
+worked. We answered as good as we could, and even convinced him to
+help us with translations. And today I managed to get an interview
+with him, to learn more about him.</p>
+
+<p><strong>Who are you, and how do you spend your days?</strong></p>
+
+<p>I'm a 25 year old free software enthusiast, living in Romania,
+which is also my country of origin. Back in 2009, at a New Year's Eve
+party, I had a very nice <strike>beer</strike> discussion with a
+friend, when we realized we have no organised Debian community in our
+country. A few days later, we put together the infrastructure for such
+community and even gathered a nice Debian-ish crowd. Since then, I
+began my quest as a free software hacker and activist and I am
+constantly trying to cover as much ground as possible on that
+field.</p>
+
+<p>A few years ago I founded a small web development company, which
+provided me the flexible schedule I needed so much for my
+activities. For the last 13 months, I have been the Technical Director
+of <a href="http://ceata.org/">Fundația Ceata</a>, which is a free
+software activist organisation endorsed by the FSF and the FSFE, and
+the only one we have in our country.</p>
+
+<p><strong>How did you get in contact with the Skolelinux / Debian Edu
+project?</strong></p>
+
+<p>The idea of participating in the Debian Edu project was a surprise
+even to me, since I never used it before I began getting involved in
+it. This year I had a great opportunity to deliver a talk on
+educational software, and I knew immediately where to look. It was a
+love at first sight, since I was previously involved with some of the
+technologies the project incorporates, and I rapidly found a lot of
+ways to contribute.</p>
+
+<p>My first contributions consisted in translating the installer and
+configuration dialogs, then I found some bugs to squash (I still
+haven't fixed them yet though), and I even got my eyes on some other
+areas where I can prove myself helpful. Since the appetite for free
+software in my country is pretty low, I'll be happy to be the first
+one around here advocating for the project's adoption in educational
+environments, and maybe even get my hands dirty in creating a flavour
+for our own needs. I am not used to make very advanced plannings, so
+from now on, time will tell what I'll be doing next, but I think I
+have a pretty consistent starting point.</p>
+
+<p><strong>What do you see as the advantages of Skolelinux/Debian
+Edu?</strong></p>
+
+<p>Not a long time ago, I was in the position of configuring and
+maintaining a LDAP server on some Debian derivative, and I must say it
+took me a while. A long time ago, I was maintaining a bigger
+Samba-powered infrastructure, and I must say I spent quite a lot of
+time on it. I have similar stories about many of the services included
+with Skolelinux, and the main advantage I see about it is the
+out-of-the box availability of them, making it quite competitive when
+it comes to managing a school's network, for example.</p>
+
+<p>Of course, there is more to say about Skolelinux than the
+availability of the software included, its flexibility in various
+scenarios is something I can't wait to experiment "into the wild" (I
+only played with virtual machines so far). And I am sure there is a
+lot more I haven't discovered yet about it, being so new within the
+project.</p>
+
+<p><strong>What do you see as the disadvantages of Skolelinux / Debian
+Edu?</strong></p>
+
+<p>As usual, when it comes to Debian Blends, I see as the biggest
+disadvantage the lack of a numerous team dedicated to the
+project. Every day I see the same names in the changelogs, and I have
+a constantly fear of the bus factor in this story. I'd like to see
+Debian Edu advertised more as an entry point into the Debian
+ecosystem, especially amongst newcomers and students. IMHO there are a
+lot low-hanging fruits in terms of bug squashing, and enough
+opportunities to get the feeling of the Debian Project's dynamics. Not
+to mention it's a very fun blend to work on!</p>
+
+<p>Derived from the previous statement, is the delay in catching up
+with the main Debian release and documentation. This is common though
+to all blends and derivatives, but it's an issue we can all work
+on.</p>
+
+<p><strong>Which free software do you use daily?</strong></p>
+
+<p>I can hardly imagine myself spending a day without Vim, since my
+daily routine covers writing code and hacking configuration files. I
+am a fan of the Awesome window manager (but I also like the
+Enlightenment project a lot!),
+<a href="http://www.claws-mail.org/">Claws Mail</a> due to its ease of
+use and very configurable behaviour. Recently I fell in love with
+<a href="https://launchpad.net/redshift">Redshift</a>, which helps me
+get through the night without headaches. Of course, there is much more
+stuff in this bag, but I'll need a blog on my own for doing this!</p>
+
+<p><strong>Which strategy do you believe is the right one to use to
+get schools to use free software?</strong></p>
+
+<p>Well, on this field, I cannot do much more than experiment right
+now. So, being far from having a recipe for success, I can only assume
+that:</p>
+
+<ul>
+
+<li>schools would like to get rid of proprietary software</li>
+
+<li>students will love the openness of the system, and will want to
+ experiment with it - maybe we need to harvest the native curiosity
+ of teenagers more?</li>
+
+<li>there is no "right one" when it comes to strategies, but it would
+ be useful to have some success stories published somewhere, so
+ other can get some inspiration from them (I know I'd promote
+ them!)</li>
+
+<li>more active promotion - talks, conferences, even small school
+ lectures can do magical things if they encounter at least one
+ person interested. Who knows who that person might be? ;-)</li>
+
+</ul>
+
+<p>I also see some problems in getting Skolelinux into schools; for
+example, in our country we have a great deal of corruption issues, so
+it might be hard(er) to fight against proprietary solutions. Also,
+people who relied on commercial software for all their lives, would be
+very hard to convert against their will.</p>

- <div class="date"> 1st May 2013</div>
- <div class="body"><p>For noen uker siden, innen fristen 2013-04-15, leverte jeg og
-Morten Kjelkenes vårt bidrag til
-<a href="http://www.apps4norge.no/">DIFIs apps4norge-konkurranse</a>
-under lagnavnet <a href="http://www.nuug.no/">NUUG</a>s tannlegeteam.
-Vi leverte følgende i idé-kategorien:</p>
-
-<blockquote>
-
-<p><strong>Tittel: Stikk innom tannlegen</strong><p>
-
-<p><a href="http://people.skolelinux.org/pere/blog/images/2013-05-01-tannlegeportal.jpeg"><img width="70%" src="http://people.skolelinux.org/pere/blog/images/2013-05-01-tannlegeportal.jpeg"></a></p>
-
-<p><strong>Beskrivelse:</strong><p>
-
-<p><em>Idéen</em>
-
-<p>Gjøre det enklere å finne en tannlege som er praktisk for deg, der
-pris og reisetid med kollektivt, til fots eller med bil er tatt med i
-beregningen, ved å oppgi hvor en bor og jobber, og få forslag til
-tannleger både i nærheten og på veien mellom disse stedene.</p>
-
-<p>Brukeren oppgir hjemmeadresse og jobbadresse, og kanskje også
-barnehage. Så kan en også oppgi egen timelønn (for å beregne taps
-arbeidsfortjeneste) og om en reiser med kollektivt, til fots eller
-kjører bil. Så trykker en søk, og får opp en todelt side med kart og
-tekstliste. I kartdelen vises aktuelle tannleger (for eksempel maks
-7), og i tekstdelen er de samme tannlegene listet opp, med pris og
-reisetid for kollektivtransport, og pris pluss reisekostnad hvis en
-reiser med bil. En kan endre sorteringsrekkefølge for listen ved å
-trykke på aktuell kolonne, og velge om en skal sortere på pris,
-reisetid eller totalkostnad. Kun tannleger som tar imot nye kunder tas
-i utganspunktet med i listen. Når brukeren trykker med musa en
-tannlegemarkør på kartet kommer det en popup med detaljer om
-tannlegen, den samme informasjonen som finnes i listen under kartet,
-og lenke til mer informasjon om tannlegen.</p>
-
-<p>For hvert enkelt tannlegekontor er det tilgjengelig en
-informasjonsside med adresse, hjemmesideurl, telefonnummer, lenke til
-side for å finne reisebeskrivelse, åpningstider, etc.</p>
-
-<p><em>Nytteverdi for brukeren</em></p>
-
-<ul>
-<li>sparer tid på tannlegebesøk</li>
-<li>kan utnytte normal reisevei mellom hjem/jobb/barnehage</li>
-<li>kan finne aktuell tannlege basert på flere kriterier</li>
-<li>sile bort tannleger som ikke tar imot flere kunder</li>
-<li>får kart som viser tannleger i nærheten, på tvers av kommunegrenser</li>
-</ul>
-
-<p><em>Grad av innovasjon, nytenkning og kreativitet</em></p>
-
-<p>Enkel tjeneste som fokuserer på det vi selv mener er relevant ved valg
-av tannlege.</p>
-
-<p>Tjenestekonseptet kan også brukes til andre næringer, f.eks. lege,
-butikk, leiebiler, hvis en har aktuell datakilde å koble med.</p>
-
-<p>Skulle gjerne hatt med vurdering av tannlegene tilgjengelig, slik
-at en kunne finne "flinke" tannleger basert på et eller annet
-kriterium.</p>
-
-<p><em>Markedspotensiale - potensiale for å slå gjennom hos mange
-brukere</em></p>
-
-<ul>
-<li>Alle som ønsker eller vurderer å skaffe seg ny tannlege, f.eks. nyinnflyttede og studenter</li>
-<li>Familier med en travel hverdag</li>
-</ul>
-
-<p>Felles er at den gjør tannlegen lettere tilgjengelig for de som vil spare tid eller penger.</p>
-
-<p><em>Samfunnsøkonomisk nytte - bidrar til å løse
-samfunnsutfordringer</em></p>
-
-<p>Kutter tid brukt på tannlegebesøk, og penger frigjøres som kan brukes på andre områder. Oppfordrer til bedre bruk av kollektivtransport ved å gi tips om tannleger i nærheten av allerede brukt reisevei mellom hjemme og jobb når en reiser kollektivt.</p>
-
-<p><em>X-faktor - “Det lille ekstra...”</em></p>
-
-<p>Denne tjenesten gir det lille ekstra ved at den ikke slår opp
-avstand til tannlege fra et enkelt punkt men avstand fra en reisevei,
-slik at en får flere tannleger å velge imellom og kanskje kan spare
-enda mer tid og penger enn en ville gjort ved å sjekke kun de nærmest
-hjemme eller jobb.</p>
-
-<p>Tjenesten gir informasjonen både som kart og som tekstlig oversikt, for å sikre at blinde og svaksynte kan få tilgang til informasjonen selv om de ikke får brukt kartvisningen.</p>

+ <div class="title"><a href="http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Jonathan_Carter.html">Debian Edu interview: Jonathan Carter</a></div>
+ <div class="date">12th June 2013</div>
+ <div class="body"><p>There is a certain cross-over between the
+<a href="http://www.skolelinux.org/">Debian Edu / Skolelinux
+project</a> and <a href="http://www.edubuntu.org/">the Edubuntu
+project</a>, and for example the LTSP packages in Debian are a joint
+effort between the projects. One person with a foot in both camps is
+Jonathan Carter, which I am now happy to present to you.</p>
+
+<p><strong>Who are you, and how do you spend your days?</strong></p>
+
+<p>I'm a South-African free software geek who lives in Cape Town. My
+days vary quite a bit since I'm involved in too many things. As I'm
+getting older I'm learning how to focus a bit more :)</p>
+
+<p>I'm also an Edubuntu contributor and I love when there are
+opportunities for the Edubuntu and Debian Edu projects to benefit from
+each other.</p>
+
+<p><strong>How did you get in contact with the Skolelinux / Debian Edu
+project?</strong></p>
+
+<p>I've been somewhat familiar with the project before, but I think my
+first direct exposure to the project was when I met Petter
+[Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in 2005 in
+London. They provided great feedback that helped the bootstrapping of
+Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and
+it was great getting input from people who have been around longer. I
+was also still very excitable and said yes to everything and to this
+day I have a big todo list backlog that I'm catching up with. I think
+over the years the relationship between Edubuntu and Debian-Edu has
+been gradually improving, although I think there's a lot that we could
+still improve on in terms of working together on packages. I'm sure
+we'll get there one day.</p>
+
+<p><strong>What do you see as the advantages of Skolelinux / Debian
+Edu?</strong></p>
+
+<p>Debian itself already has so many advantages. I could go on about
+it for pages, but in essence I love that it's a very honest project
+that puts its users first with no hidden agendas and also produces
+very high quality work.</p>
+
+<p>I think the advantage of Debian Edu is that it makes many common
+set-up tasks simpler so that administrators can get up and running
+with a lot less effort and frustration. At the same time I think it
+helps to standardise installations in schools so that it's easier for
+community members and commercial suppliers to support.</p>
+
+<p><strong>What do you see as the disadvantages of Skolelinux / Debian
+Edu?</strong></p>
+
+<p>I had to re-type this one a few times because I'm trying to
+separate "disadvantages" from "areas that need improvement" (which is
+what I originally rambled on about)</p>
+
+<p>The biggest disadvantage I can think of is lack of manpower. The
+project could do so much more if there were more good contributors. I
+think some of the problems are external too. Free software and free
+content in education is a no-brainer but it takes some time to catch
+on. When you've been working with the same proprietary eco-system for
+years and have gotten used to it, it can be hard to adjust to some
+concepts in the free software world. It would be nice if there were
+more Debian Edu consultants across the world. I'd love to be one
+myself but I'm already so over-committed that it's just not possible
+currently.</p>
+
+<p>I think the best short-term solution to that large-scale problem is
+for schools to be pro-active and share their experiences and grow
+their skills in-house. I'm often saddened to see how much money
+educational institutions spend on 3rd party solutions that they don't
+have access to after the service has ended and they could've gotten so
+much more value otherwise by being more self-sustainable and
+autonomous.</p>
+
+<p><strong>Which free software do you use daily?</strong></p>
+
+<p>My main laptop dual-boots between Debian and Windows 7. I was
+Windows free for years but started dual-booting again last year for
+some games which help me focus and relax (Starcraft II in
+particular). Gaming support on Linux is improving in leaps and bounds
+so I suppose I'll soon be able to regain that disk space :)</p>
+
+<p>Besides that I rely on Icedove, Chromium, Terminator, Byobu, irssi,
+git, Tomboy, KVM, VLC and LibreOffice. Recently I've been torn on
+which desktop environment I like and I'm taking some refuge in Xfce
+while I figure that out. I like tools that keep things simple. I enjoy
+Python and shell scripting. I went to an Arduino workshop recently and
+it was awesome seeing how easy and simple the IDE software was to get
+up and running in Debian compared to the users running Windows and OS
+X.</p>
+
+<p>I also use mc which some people frown upon slightly. I got used to
+using Norton Commander in the early 90's and it stuck (I think the
+people who sneer at it is just jealous that they don't know how to use
+it :p)
+
+<p><strong>Which strategy do you believe is the right one to use to
+get schools to use free software?</strong></p>
+
+<p>I think trying to force it is unproductive. I also think that in
+many cases it's appropriate for schools to use non-free systems and I
+don't think that there's any particular moral or ethical problem with
+that.</p>
+
+<p>I do think though that free software can already solve so so many
+problems in educational institutions and it's just a shame not taking
+advantage of that.</p>
+
+<p>I also think that some curricula need serious review. For example,
+some areas of the world rely heavily on very specific versions of MS
+Office, teaching students to parrot menu items instead of learning the
+general concepts. I think that's very unproductive because firstly, MS
+Office's interface changes drastically every few years and on top of
+that it also locks in a generation to a product that might not be the
+best solution for them.</p>
+
+<p>To answer your question, I believe that the right strategy is to
+educate and inform, giving someone the information they require to
+make a decision that would work for them.</p>
