- <div class="body"><p>Min venn Erik Vold har på vegne av styret i
-<a href="http://www.frikanalen.no/">Frikanalen</a> sendt ut
-<a href="http://lists.nuug.no/pipermail/frikanalen/2013-March/000054.html">følgende
-epost</a> til alle kanalens medlemmer og støttespillere, i et forsøk
-på å redde kanalen etter at kulturdepartementet kuttet all
-finansiering i fjor høst. Jeg fikk meldingen som
-<a href="http://www.nuug.no/">NUUG</a>-styremedlem, og mener den
-trenger et større publikum. Jeg gjengir den derfor i sin helhet,
-inkludert lenken til budsjett og regnskapsutkast, etter
-<a href="http://lists.nuug.no/pipermail/frikanalen/2013-March/000061.html">avtale
-med Erik</a>.</p>
-
-<p><blockquote>
-<p>Til Frikanalens støttespillere</p>
-
-<p>Frivillighetens TV kanal har med minimal støtte avviklet daglige
-sendinger siden 2009 og til tross for at statsstøtten uteble i år, er
-vi nå i full gang med å utvikle et nytt TV system som foreningen selv
-vil eie. Departementet fikk dessverre ikke med seg at nettet vil
-berike TV sendingen fremfor å gjøre den overflødig. De har nå overlatt
-finansieringen av videre drift til frivilligheten og vi håper derfor
-på deres hjelp til å søke om midler. På kjøpet får dere langt flere
-muligheter til å nå ut med deres budskap og med utbyggingen av Hybrid
-TV (nett på TV) kan vi sammen motbevise departementets påstand.</p>
-
-<p>Kostnaden med denne utviklingen er svært lav ettersom de fleste
-programmererne jobber gratis og alt er basert på åpen kildekode der
-man deler hverandres bidrag til kringkastingsorienterte systemer. I
-samarbeid med flere europeiske kanaler i EBU (SVT, BBC, NRK, ZDF, ARD,
-France Televisions etc) ønsker vi å bygge opp et nettverk for delt
-support og åpen kildekode der Frikanalen er den eneste sandkassen hvor
-ny teknologi kan testes på luft. Riks TV åpner for annonsering av
-nettinnhold relatert til det du ser på TV (streamevents i HbbTV)
-allerede i sommer. Med støtte fra Media Netwerk som drifter Frikanalen
-samt Sofia Digital som stiller med Hybrid TV server er vi & NRK sikret
-en sentral rolle i utprøvingen. Det vil da bli mulig og streame
-direkte til Riks TV sine nye mottakere (og nye IDTV'er) i HD samt at
-TV'n kan annonsere en link til deres organisasjonssider, med
-oppdaterte nyheter (RSS feeds), relaterte videoer etc., under
-avviklingen av deres innslag.</p>
-
-<p>Vi tror sendingene på den nye nettstyrte TV-kanalen vil bli rikere enn
-på den kommersielle plattformen vi har vært på så langt. Brukerne vil
-nå få en tettere integrasjon med sosiale medier samt at innholdet
-etterhvert kommer ut på Hybrid TV og mobile enheter. Teknisk ansvarlig
-i Frikanalen, Erik Vold, er sentral i utviklingen av streamingdelen
-for tv.nrk.no (årets produkt i PC World) og erfaringen NRK har gjort
-på mobile enheter kan videreføres til oss. Det er heller ingen tvil om
-at Hybrid TV vil bli en suksess også i Norge. Erik sitter i Nordig som
-har vedtatt en felles standard for de nordiske kringkasterne basert på
-HbbTV. Denne standarden bruker web-protokoller som gjør det like
-enkelt og billig å utvikle tjenester for Hybrid TV som å lage en
-nettside. Samtlige nye TV apparater solgt i Norden vil ha støtte for
-HbbTV og med det tror vi oppslutningen vil bli like stor som ellers i
-Europa (Tyskland og Frankrike tredoblet antall HbbTV-brukere i
-fjor). Vi forventer også mye d rahjelp fra disse foregangslandene. Vår
-utvikler Tore Sinding Bekkedal er i skriv ende stund på en HbbTV
-workshop med EBU-medlemmer hos IRT i München der han på vegne av NRK
-og Frikanalen tester og utvikler ny stremingteknologi (MPEG- DASH) for
-mobile enheter og hybrid TV.</p>
-
-<p>Frikanalen har forøvrig flyttet inn i nye kostnadsfrie lokaler på
-Chateau Neuf. Med massiv hjelp fra frivillige og utstyr fra NRK får
-vi der en flerkameraregi i egnede lokaler. Dette åpner for debatter,
-konserter, events og mye spennende innhold i samarbeid med Student
-TV'ene.</p>
-
-<p>Med hjelp fra NUUG har også streamingdelen av systemet fått plass på
-Uninett (Forskningsparken) og dermed er vi på Norges beste
-internettlinjer. Vi åpner med dette for live mottak fra samtlige
-medlemmer og på sikt kan vi tilby HD på hybrid TV og PC / MAC / mobil.</p>
-
-<p>Avvikling på luft skjer allerede med egenutviklede løsninger i åpen
-kildekode (playout og live-koding). Det er også mulig å se første
-byggetrinn med programoversikt og videoer på nett, men foreløpig kun
-for nettleserne Opera, Chrome og Firefox:
-<a href="http://beta.frikanalen.tv/guide/">http://beta.frikanalen.tv/guide/</a>
-og
-<a href="http://beta.frikanalen.tv/video/">http://beta.frikanalen.tv/video/</a>. Kom
-gjerne med ønsker og tilbakemeldinger til vår hovedutvikler Benjamin
-Bruheim: grolgh (at) gmail.com</p>
-
-<p>Med en tettere tilknytning til Akademia og NRK, er det god grunn til å
-tro at utviklingen vil skyte fart og at vi raskere kommer ut med
-dagsaktuelt innhold.</p>
-
-<p>Vi sender i dag på Riks TV og Altibox, men ikke lenger på TV8. Det er
-viktig for våre brukere igjen å komme ut på Get og Canal Digital,
-dermed er det svært heldig at vi nå har formidlingsplikt på kabel. Til
-tross for at det tar noe tid å få nye avtaler på plass, med frivillig
-juridisk bistand, vil vi sannsynligvis komme bedre ut i andre enden
-også her. Formidlingsplikten gjelder samtlige kabeldistribusjoner i
-Norge, ikke bare de regionene TV8 hadde avtale med.</p>
-
-<p>Om alt dette skal se dagens lys er vi avhengig av en
-grunnfinansiering. Deres medlemsavgifter er i så måte et svært viktig
-bidrag som vi er veldig takknemlige for. Vi ser oss likevel nødt til
-å be dere om å delta i arbeidet med å dekke de resterende
-driftskostnader. Frikanalen sin arbeidskapasitet er betydelig redusert
-etter at foreningen ikke lenger kunne finansiere en daglig leder, men
-allmøtet kan åpne for at flere bidrar til inntjening (Ekstraordinær
-generalforsamling foreslo å tillate sponsorplakater på sendeflaten og
-deler av disse inntektene kan tilfalle kanalen). Håper alle
-medlemmene kan hjelpe oss med å skrive søknader og skaffe sponsorer,
-eller i det minste komme med gode forslag til inntjening. Det er ikke
-mye som skal til for å klare videre drift, kun 0,5 mill. pr år.</p>
-
-<p>Med en støtte som tilsvarer en norsk kortfilm vil vi kunne redde
-sendearkivet for flere tusen videoer bygget opp av frivilligheten
-gjennom 5 år og vi dobler kapasiteten for å ta imot nye (De som
-leverer HD vil for øvrig kunne få HD på nett, mobil og hybrid TV).</p>
-
-<p>Vi vil også kunne videreføre konsesjonen på Riks TV og realisere en
-formidlingsplikt på kabel som har en årlig verdi på ca. 5 millioner
-kroner (når over 2/3 av Norges befolkning).</p>
-
-<p>Uten støtte står verdens eneste nasjonale nettstyrte åpne TV kanal i
-fare for å forsvinne. En konkursbegjæring vil gjøre at utstyrsparken
-går til advokatsalærer i behandling av boet og kreditorene vil ikke
-kunne få dekket sine krav. Det mener vi ikke bare er urett ovenfor
-långiverne, men det er urett mot alle de som har bidratt med å bygge
-opp frivillighetens eneste sendearkiv og ikke minst alle de som i dag
-jobber frivillig med å videreutvikle TV-systemet.</p>
-
-<p>Håper dere i likhet med styret ser verdien i videre drift og kan melde
-tilbake innen årsmøtet (Kontaktinformasjon til styret og frivillige
-utviklere er i kopifeltet).</p>
-
-<p>Vennligst fyll ut det blå feltet i regnearket under med det dere tror
-er mulig å få inn. Det dere skriver her er ikke bindende, men gir
-styret en indikasjon på om videre drift er mulig. Det blir tatt
-stilling til av generalforsamlingen medio mars. Setter derfor pris på
-om alle kan bidra med forslag til støtte eller antatte verdier fra
-søknad/spons innen det.</p>
-
-<p>Forhåpentligvis når vi også ønsket budsjett på 1 mill. pr år. Med det
-kan vi nedbetale gjelden raskere og sørge for en bedre
-tilgjengelighet, samt raskere utvikling:</p>

-
-<p>Jeg håper noen av mine lesere med dette ser verdien av Frikanalen
-og melder seg inn for å sende sine videoer ut på TV til RiksTV og
-Altibox-seerne. Det haster. Årsmøtet i foreningen Frikanalen skal
-straks avholdes, og innen den tid må en redningsplan være på plass.
-NUUG bidrar allerede litt ved å organisere utviklersamlinger og
-finansiere litt mat og drikke til de frivillige som stiller opp på
-dugnadsbasis for å utvikle den tekniske løsningen. Det er ikke nok
-til å redde kanalen, men gir et lite steg i riktig retning.</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><a href="http://www.uhuru.biz/?p=1293">Bruk av narkohund i
- klasserom – fra vondt til verre</a> (2013-03-09)</li>
+<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><a href="http://www.uhuru.biz/?p=1018">Ulovlig og
- menneskerettsstridig bruk av narkohund i klasserom</a>
- (2012-03-12)</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>Jeg er veldig glad for at han bidrar med argumenter og forklaringer
-vi foreldre kan ta med oss når vi skal protestere på og få en slutt på
-denne forkastelige praksisen. Narkotikaproblemet må adresseres på
-andre måter som ikke krenker barn og ungdoms integritet. Jeg ønsker
-ikke at mine barn skal læres opp til å akseptere radering av
-privatlivets fred, men heller at de skal læres opp til å sloss imot
-den innføringen av stadig mer totalitær overvåkning som har pågått
-over mange år i Norge. </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"> 3rd March 2013</div>
- <div class="body"><p>Do you want to set up your own TV station, schedule videos and
-broadcast them on the air? Using free software? With video on demand
-support using
-<a href="http://www.digistan.org/open-standard:definition">free and
-open standards</a>? Included a web based video stream as well? And
-administrate it all in your web browser from anywhere in the world? A
-few years now the Norwegian public access TV-channel
-<a href="http://www.frikanalen.no/">Frikanalen</a> have been building a
-system to do just this. The source code for the solution is licensed
-using the GNU LGPL, and
-<a href="http://github.com/Frikanalen">available from github</a>.</p>
-
-<p>The idea is simple. You upload a video file over the web, and
-attach meta information to the file. You select a time slot in the
-program schedule, and when the time come it is played on the air and
-in the web stream. It is also made available in a video on demand
-solution for anyone to see it also outside its scheduled time. All
-you need to run a TV station - using your web browser.</p>
-
-<p>There are several parts to this web based solution. I'll mention
-the three most important ones. The first part is the database of
-videos and the schedule. This is written in Django and include a REST
-API. The current database is SQLite, but the plan is to migrate it to
-PostgreSQL. At the moment this system can be tested on
-<a href="http://beta.frikanalen.tv/">beta.frikanalen.tv</a>. The
-second part is the video playout, taking the schedule information from
-the database and providing a video stream to broadcast. This is done
-using <a href="http://www.casparcg.com/">CasparCG from SVT</a> and
-<a href="http://www.mltframework.org/">Media Lovin' Toolkit</a>. Video
-signal distribution is handled using
-<a href="http://www.ob-encoder.com/">Open Broadcast Encoder</a>. The
-third part is the converter, handling the transformation of uploaded
-video files to a format useful for broadcasting, streaming and video
-on demand. It is still very much work in progress, so it is not yet
-decided what it will end up using. Note that the source of the latter
-two parts are not yet pushed to github. The lead author want to clean
-them up a bit more first.</p>
-
-<p>The development is coordinated on the
-<a href="irc://irc.freenode.net/%23frikanalen">#frikanalen IRC
-channel</a> (irc.freenode.net), and discussed on
-<a href="http://lists.nuug.no/mailman/listinfo/frikanalen">the
-frikanalen mailing list</a>. The lead developer is Benjamin Bruheim
-(phed on IRC). Anyone is welcome to participate in the
-development.</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">22nd February 2013</div>
- <div class="body"><p>Etter en lang pause og travle uker har jeg endelig klart å få
-samlet et nytt intervju med en av folkene i
-<a href="http://www.skolelinux.org/">Skolelinux</a>-miljøet.
-Denne gang er det Helge Tore Høyland, en mangeårig bidragsyter på
-epostlistene og ellers i prosjektet.</p>
-
-<p><strong>Hvem er du, og hva driver du med til daglig?</strong></p>
-
-<p>Eg er IT-konsulent/teknikker hjå eit firma i Steinkjer med navn
-<a href="http://unoit.no/">Uno IT</a>. Uno IT er eit lite firma som
-drifter nettverk og maskiner for små og mellomstore firma
-Steinkjer-området. Per dags dato er me 2 ansatte. Min faglege bakgrunn
-er Fagbrev som it-teknikker, samt nokre fag innen nettverk- og
-server-drift frå HiST og NTNU. Dagleg arbeid består i oppsett av nye
-maskiner og hjelp til sluttbrukere, samt oppsett og vedlikehold av eit
-vidt spekter av fagsystemer ute hjå kunder. Erfaring med Skolelinux
-har eg hatt i forbindelse med drifting av
-<a href="http://www.bjorkly.no/">Bjørkly skule</a>, ein privat
-grunnskule i Namsos-området. I dag har skulen 65 elever, 15 lærere, 1
-hovedserver og ca 60 klienter som kjører halvtjukt. Eg har bygd og
-driftet systemet sidan summaren 2006.</p>
-
-<p><strong>Hvordan kom du i kontakt med Skolelinux-prosjektet?</strong></p>
-
-<p>Eg kom i kontakt med Skolelinux-prosjektet via ein artikkel i eit
-fagblad, som eg ikkje lenger hugsar namnet på. I og med at eg allereie
-hadde pusla med nettverk for ein annan skule, fatta eg straks
-interesse for prosjektet.</p>
-
-<p><strong>Hva er fordelene med Skolelinux slik du ser det?</strong></p>
-
-<p>Fordelane med Skolelinux er sentralisert administrasjon og svært
-mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte 60
-klientar med berre å «bry» seg med ein server. Levetid for systemets
-hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt
-sikkerhet og mindre lisenskostnader. Etter min erfaring er det og
-mykje mindre driftskostnader med eit slikt system enn konkurrerande
-system, pga enkelhet med sentralisert administrasjon. På grunn av at
-Skolelinux er basert på Debian er det òg svært stabilt.</p>
-
-<p><strong>Hva er ulempene med Skolelinux slik du ser det?</strong></p>
-
-<p>Ulemper er mangel på vilje til å følge standarer ute i markedet,
-som fører til mangel på støtte til nokre mykje brukte ting. Flash og
-Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å
-ha nyeste pakke av eit program, kan ein i nokre tilfeller kome borti
-at program vert «for gamle». Det er spesielt nettlesaren som er
-utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg,
-for «alle» platformer fører òg til noko hovudbry.</p>
-
-<p><strong>Hvilken fri programvare bruker du til daglig?</strong></p>
-
-<p>Til dagleg bruker eg svært mange forskjellige «fri programvare»
-program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla,
-OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.</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>Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så
-fokusert på at det er fri programvare men at det skal «berre fungere».
-Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux
-sin del må ein få eit betre fokus på overganger. Utbytting av servere
-må gå meir automatisk, import og eksport av brukerbase og maskinbase
-med meir må kunne gå enkelt og oppgradering til neste versjon må bli
-mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette
-opp frå start når ein byter ut ein server eller oppgraderer til neste
-versjon. For å få Skolelinux til å bli eit betre alternativ for skular
-må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte
-dei protokollar og tillegg som vert brukt av forlag med meir. Etter
-kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og
-viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i
-bruk opne standarer, men inntil det skjer, må systemet kunne brukast
-mot desse fagsystema.</p>
-
-<p>For meg har prosjektet med Skolelinux vore ein svært artig og
-lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok,
-men det er svært hjelpevillig og engasjert.</p>

+ <div class="date"> 3rd July 2013</div>
+ <div class="body"><p>The fourth wheezy based alpha release of Debian Edu was wrapped up
+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>
+ <li>Updated artwork matching http://wiki.debian.org/DebianArt/Themes/Joy
+ <li>Multi-arch i386/amd64 USB stick ISO available.</li>
+ <li>Got rid of ispell/wordlist related debconf questions that showed
+ up for some language options.</li>
+ <li>Switched to using http.debian.net as APT source by default.</li>
+ <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>
+ <li>Update system to handle hardware quirks (debian-edu-hwsetup).</li>
+ <li>Corrected PXE installation setup to properly pass selected desktop
+ and keymap settings to PXE installation clients.</li>
+ <li>LTSP diskless workstations use sshfs by default, allowing them to
+ work without adding them to DNS and NIS netgroups for NFS access.</li>
+</ul>
+<p><strong>Known issues</strong></p>
+<ul>
+ <li>No mass import of user account data in GOsa (ldif or csv)
+ available yet (698840).</li>
+ <li>Artwork not enabled for all desktops.</li>

- <div class="date">12th February 2013</div>
- <div class="body"><p>Here in Norway, electronic invoices are spreading, and the
-<a href="http://www.anskaffelser.no/e-handel/faktura">solution promoted
-by the Norwegian government</a> require that invoices are sent through
-one of the approved facilitators, and it is not possible to send
-electronic invoices without an agreement with one of these
-facilitators. This seem like a needless limitation to be able to
-transfer invoice information between buyers and sellers. My preferred
-solution would be to just transfer the invoice information directly
-between seller and buyer, for example using SMTP, or some HTTP based
-protocol like REST or SOAP. But this might also be overkill, as the
-"electronic" information can be transferred using paper invoices too,
-using a simple bar code. My bar code encoding of choice would be QR
-codes, as this encoding can be read by any smart phone out there. The
-content of the code could be anything, but I would go with
-<a href="http://en.wikipedia.org/wiki/VCard">the vCard format</a>, as
-it too is supported by a lot of computer equipment these days.</p>
-
-<p>The vCard format support extentions, and the invoice specific
-information can be included using such extentions. For example an
-invoice from SLX Debian Labs (picked because we
-<a href="http://www.linuxiskolen.no/slxdebianlabs/donations.html">ask
-for donations to the Debian Edu project</a> and thus have bank account
-information publicly available) for NOK 1000.00 could have these extra
-fields:</p>

-<p><strong>Update 2013-02-12 11:30</strong>: Added KID to the proposal
-based on feedback from Sturle Sunde.</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>

+ <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>

-<p>With kids in the house, one challenge is getting them to sleep
-during the night and wake up when it is morning. I mean, when I
-believe it is morning, and not two hours earlier. In our household we
-have decided that 07:00 is the turning point, but getting the kids to
-sleep until 07:00 is a small challenge every day. They have adapted
-quite well, and rarely wake up at 05:00 any more, but some times wake
-up at times like 05:50, 06:15, 06:30 or 06:45, and it is hard to put
-the awake one to bed again without disturbing and waking the rest.
-And I understand perfectly well that they fail to sleep until 07:00
-some times, as there is no way for them to know if it is before or
-after the magic moment without coming and asking us parents.</p>
-
-<p>But yesterday I came up with a method to solve this problem. It
-involve home automation. A few years ago I bought a
-<a href="http://www.telldus.se/products/tellstick">Tellstick</a> and RF
-switches at the local <a href="http://www.clasohlson.com/">Clas
-Ohlson</a> shop, allowing me to control lights and other electrical
-gadgets using my Linux server. When I moved from the old flat to a
-small house, I put away all this equipment as most of the lighting in
-the house was not using wall sockets and thus not easy to connect to
-the gadgets I had. But recently I bought a
-<a href="http://www.telldus.se/products/tellstick_net">Tellstick
-Net</a> to be able to read sensor input as well as control power
-sockets. I want to control ovens in the basement to avoid the pipes
-to freeze, and monitor the humidity to detect flooding. The default
-setup for Tellstick Net is to be controlled by the vendor web service,
-which to me is a security problem, but it is also possible to build
-ones own
-<a href="http://developer.telldus.com/blog/2012/03/02/help-us-develop-local-access-using-tellstick-net-build-your-own-firmware">firmware
-with local access</A> instead of being controlled by a Swedish
-company, thanks to the release of the GPL licensed firmware source
-code. I plan to get that running before I let it control anything
-important. But while working on this, one idea to make it easier for
-the kids came to me yesterday. We can set up a night light controlled
-by the computer, and turn it automatically on at 07:00. The kids can
-then check the light in the morning to know if they are supposed to
-get up or not. They joined me in setting everything up, and I
-repeated the concept several times before bed times to make sure they
-remembered to check the light before getting up in the morning.</p>
-
-<p>We tested it this morning, and all the kids stayed in bed until
-after 07:00, and every one of them commented on the fact that the
-"morning light" was turned on and signalled that the morning had
-arrived. So this look like a success, and I am excited to see how
-this develops the next few days. :) I really hope this can allow us
-all to sleep a bit longer in the morning.</p>
-
-<p>A nice advantage of this setup is that we can remote control when
-to tell the kids to get up. We do not have to wait until 07:00, and
-can also delay it if we want to.</p>

+ <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>
