Til frikanalens støttespillere - fra styret i Frikanalen
-
13th March 2013
-

Min venn Erik Vold har på vegne av styret i Frikanalen sendt ut -følgende epost 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 NUUG-styremedlem, og -mener den trenger et større publikum. Jeg gjengir den derfor i sin -helhet, inkludert lenken til budsjett og regnskapsutkast, etter avtale -med Erik.

Til Frikanalens støttespillere

- -

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.

- -

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.

- -

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.

- -

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.

- -

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.

- -

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: -http://beta.frikanalen.tv/guide/ -og -http://beta.frikanalen.tv/video/. Kom -gjerne med ønsker og tilbakemeldinger til vår hovedutvikler Benjamin -Bruheim: grolgh (at) gmail.com

- -

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.

- -

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.

- -

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.

- -

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).

- -

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).

- -

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.

- -

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).

- -

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.

- -

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:

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.

Recipe to test the Freedombox project on amd64 or Raspberry Pi
+
10th September 2013
+

I was introduced to the +Freedombox project +in 2010, when Eben Moglen presented his vision about serving the need +of non-technical people to keep their personal information private and +within the legal protection of their own homes. The idea is to give +people back the power over their network and machines, and return +Internet back to its intended peer-to-peer architecture. Instead of +depending on a central service, the Freedombox will give everyone +control over their own basic infrastructure.

+ +

I've intended to join the effort since then, but other tasks have +taken priority. But this summers nasty news about the misuse of trust +and privilege exercised by the "western" intelligence gathering +communities increased my eagerness to contribute to a point where I +actually started working on the project a while back.

+ +

The initial +Debian initiative based on the vision from Eben Moglen, is to +create a simple and cheap Debian based appliance that anyone can hook +up in their home and get access to secure and private services and +communication. The initial deployment platform have been the +Dreamplug, +which is a piece of hardware I do not own. So to be able to test what +the current Freedombox setup, I had to come up with a way to install +it on some hardware I do got access to. I have rewritten the +freedom-maker +image build framework to use .deb packages instead of only copying +setup into the boot images, and thanks to this rewrite I am able to +set up any machine supported by Debian Wheezy as a Freedombox, using +the previously mentioned deb (and a few support debs for packages +missing in Debian).

+ +

The current Freedombox setup consist of a set of bootstrapping +scripts +(freedombox-setup), +and a administrative web interface +(plinth + exmachina + +withsqlite), as well as a privacy enhancing proxy based on +privoxy +(freedombox-privoxy). There is also a web/javascript based XMPP +client (jwchat) +trying (unsuccessfully so far) to talk to the XMPP server +(ejabberd). The +web interface is pluggable, and the goal is to use it to enable OpenID +services, mesh network connectivity, use of TOR, etc, etc. Not much of +this is really working yet, see +the +project TODO for links to GIT repositories. Most of the code is +on github at the moment. The HTTP proxy is operational out of the +box, and the admin web interface can be used to add/remove plinth +users. I've not been able to do anything else with it so far, but +know there are several branches spread around github and other places +with lots of half baked features.

+ +

Anyway, if you want to have a look at the current stat, the +following recipes should work to give you a test machine to poke +at.

+ +

Debian Wheezy amd64

+ +
    + +
  1. Fetch normal Debian Wheezy installation ISO.
    2. +
  2. Boot from it, either as CD or USB stick.
    3. +

  3. Press [tab] on the boot prompt and add this as a boot argument +to the Debian installer:

    +

    url=http://www.reinholdtsen.name/freedombox/preseed-wheezy.dat
    4. + +
  4. Answer the few language/region/password questions and pick disk to +install on.
    5. + +
  5. When the installation is finished and the machine have rebooted a +few times, your Freedombox is ready for testing.
    6. + +
+ +

Raspberry Pi Raspbian

+ +
    + +
  1. Fetch a Raspbian SD card image, create SD card.
    2. +
  2. Boot from SD card, extend file system to fill the card completely.
    3. +

  3. Log in and add this to /etc/sources.list:

    +
    +deb http://www.reinholdtsen.name/freedombox wheezy main
+
    4. +

  4. Run this as root:

    +
    +wget -O - http://www.reinholdtsen.name/freedombox/BE1A583D.asc | \
+   apt-key add -
+apt-get update
+apt-get install freedombox-setup
+/usr/lib/freedombox/setup
+
    5. +
  5. Reboot into your freshly created Freedombox.
    6. + +
+ +

You can test it on other architectures too, but because the +freedombox-privoxy package is binary, it will only work as intended on +the architectures where I have had time to build the binary and put it +in my APT repository. But do not let this stop you. It is only a +short "apt-get source -b freedombox-privoxy" away. :)

+ +

Note that by default Freedombox is a DHCP server on the +192.168.1.0/24 subnet, so if this is your subnet be careful and turn +off the DHCP server by running "update-rc.d isc-dhcp-server +disable" as root.

+ +

Please let me know if this work for you, or if you have any +problems. We gather on the IRC channel +#freedombox on +irc.debian.org and the +project +mailing list.

+ +

Once you get your freedombox operational, you can visit +http://your-host-name:8001/ to see the state of the plint +welcome screen (dead end - do not be surprised if you are unable to +get past it), and next visit http://your-host-name:8001/help/ +to look at the rest of plinth. The default user is 'admin' and the +default password is 'secret'.

Osloskolen bryter loven når de sender politihunder inn i klasserom med elever
-
10th March 2013
-

Om noen år skal mine barn antagelig begynne på skolen i Oslo. Der -skal de blant annet lære seg å verdsette og håndheve sine egne grenser -og beskytte sin personlige integritet og privatsfære. Det blir ikke -enkelt når ledelsen i Osloskolen med vitende og vilje legger opp til å -krenke elevenes privatsfære ved å la politiet ransake elevene med -narkohund i klasserommet. Jon Wessel-Aas har publisert noen -interessante kommentarer om hvorfor dette er ulovlig. +

Datalagringsdirektivet gjør at Oslo Høyre og Arbeiderparti ikke får min stemme i år
+
8th September 2013
+

I 2011 raderte et stortingsflertall bestående av Høyre og +Arbeiderpartiet vekk en betydelig del av privatsfæren til det norske +folk. Det ble vedtatt at det skulle registreres og lagres i et halvt +år hvor alle som bærer på en mobiltelefon befinner seg, hvem de +snakker med og hvor lenge de snakket sammen. Det skal også +registreres hvem de sendte SMS-meldinger til, hvem en har sendt epost +til, og hvilke nett-tjenere en besøkte. Saken er kjent som +Datalagringsdirektivet +(DLD), og innebærer at alle innbyggerne og andre innenfor Norges +grenser overvåkes døgnet rundt. Det ble i praksis innført brev og +besøkskontroll av hele befolkningen. Rapporter fra de landene som +allerede har innført slik total lagring av borgernes +kommunikasjonsmønstre forteller at det ikke hjelper i +kriminalitetsbekjempelsen. Den norske prislappen blir mange hundre +millioner, uten at det ser ut til å bidra positivt til politiets +arbeide. Jeg synes flere hundre millioner i stedet burde vært brukt +på noe som kan dokumenteres å ha effekt i kriminalitetsbekjempelsen. +Se mer på +Wikipedia +og Jon Wessel-Aas.

+ +

Hva er problemet, tenkter du kanskje? Et åpenbart problem er at +medienes kildevern i praksis blir radert ut. Den innsamlede +informasjonen gjør det mulig å finne ut hvem som har snakket med +journalister på telefon, SMS og epost, og hvem som har vært i nærheten +av journalister så sant begge bar med seg en telefon. Et annet er at +advokatvernet blir sterkt redusert, der politiet kan finne ut hvem +som har snakket med en advokat når, eller vært i møter en med advokat. +Et tredje er at svært personlig informasjon kan avledes fra hvilke +nettsteder en har besøkt. Har en besøkt hivnorge.no, +swingersnorge.com eller andre sider som kan brukes til avlede +interesser som hører til privatsfæren, vil denne informasjonen være +tilgjengelig takket være datalagringsdirektivet.

+ +

De fleste partiene var mot, kun to partier stemte for. Høyre og +Arbeiderpartiet. Og både Høyre og Arbeiderpartiet i Oslo har +DLD-forkjempere på toppen av sine lister (har ikke sjekket de andre +fylkene). Det er dermed helt uaktuelt for meg å stemme på disse +partiene. Her er oversikten over partienes valglister i Oslo, med +informasjon om hvem som stemte hva i første DLD-votering i Stortinget, +basert på informasjon fra mine venner i +Holder de +Ord samt data.stortinget.no. +Først ut er stortingslista fra Høyre for Oslo:

    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. Immediately after installation a school server running all +services needed for a school network is set up just waiting for users +and machines being added via GOsa², a comfortable Web-UI. A netbooting +environment is prepared using PXE, so after initial installation of +the main server from CD or USB stick all other machines can be +installed via the network. The provided school server provides LDAP +database and Kerberos authentication service, centralized home +directories, DHCP server, web proxy and many other services. The +desktop contains +more +than 60 educational software packages and more are available from +the Debian archive, and schools can choose between KDE, Gnome, LXDE +and Xfce desktop environment.

    + +

    This is the sixth test release based on Debian Wheezy. Basically this +is an updated and slightly improved version compared to the Squeeze +release.

    + +

    ALERT: Alpha based installations should reinstall or downgrade the +versions of gosa and libpam-mklocaluser to the ones used in this beta +release. Both alpha and beta0 based installations should reinstall or +deal with gosa.conf manually; there are two options: (1) Keep +gosa.conf and edit this file as outlined +on +the mailing list. (2) Accept the new version of gosa.conf and +replace both contained admin password placeholders with the password +hashes found in the old one (backup copy!). In both cases every user +need to change their their password to make sure a password is set for +CIFS access to their home directory.

    Frikanalen - Complete TV station organised using the web
    -
    3rd March 2013
    -

    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 -free and -open standards? 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 -Frikanalen have been building a -system to do just this. The source code for the solution is licensed -using the GNU LGPL, and -available from github.

    - -

    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.

    - -

    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 -beta.frikanalen.tv. 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 CasparCG from SVT and -Media Lovin' Toolkit. Video -signal distribution is handled using -Open Broadcast Encoder. 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.

    - -

    The development is coordinated on the -#frikanalen IRC -channel (irc.freenode.net), and discussed on -the -frikanalen mailing list. The lead developer is Benjamin Bruheim -(phed on IRC). Anyone is welcome to participate in the -development.

    Intel 180 SSD disk with Lenovo firmware can not use Intel firmware
    +
    18th August 2013
    +

    Earlier, I reported about +my +problems using an Intel SSD 520 Series 180 GB disk. Friday I was +told by IBM that the original disk should be thrown away. And as +there no longer was a problem if I bricked the firmware, I decided +today to try to install Intel firmware to replace the Lenovo firmware +currently on the disk.

    + +

    I searched the Intel site for firmware, and found +issdfut_2.0.4.iso +(aka Intel SATA Solid-State Drive Firmware Update Tool) which +according to the site should contain the latest firmware for SSD +disks. I inserted the broken disk in one of my spare laptops and +booted the ISO from a USB stick. The disk was recognized, but the +program claimed the newest firmware already were installed and refused +to insert any Intel firmware. So no change, and the disk is still +unable to handle write load. :( I guess the only way to get them +working would be if Lenovo releases new firmware. No idea how likely +that is. Anyway, just blogging about this test for completeness. I +got a working Samsung disk, and see no point in spending more time on +the broken disks.

    90 percent done with the Norwegian draft translation of Free Culture
    +
    2nd August 2013
    +

    It has been a while since my last update. Since last summer, I +have worked on a Norwegian +docbook version of the 2004 book +Free Culture by Lawrence Lessig, +to get a Norwegian text explaining the problems with the copyright +law. Yesterday, I finally broken the 90% mark, when counting the +number of strings to translate. Due to real life constraints, I have +not had time to work on it since March, but when the summer broke out, +I found time to work on it again. Still lots of work left, but the +first draft is nearing completion. I created a graph to show the +progress of the translation:

    + +

    + +

    When the first draft is done, the translated text need to be +proof read, and the remaining formatting problems with images and SVG +drawings need to be fixed. There are probably also some index entries +missing that need to be added. This can be done by comparing the +index entries listed in the SiSU version of the book, or comparing the +English docbook version with the paper version. Last, the colophon +page with ISBN numbers etc need to be wrapped up before the release is +done. I should also figure out how to get correct Norwegian sorting +of the index pages. All docbook tools I have tried so far (xmlto, +docbook-xsl, dblatex) get the order of symbols and the special +Norwegian letters ÆØÅ wrong.

    + +

    There is still need for translators and people with docbook +knowledge, to be able to get a good looking book (I still struggle +with dblatex, xmlto and docbook-xsl) as well as to do the draft +translation and proof reading. And I would like the figures to be +redrawn as SVGs to make it easy to translate them. Any SVG master +around? There are also some legal terms that are unfamiliar to me. +If you want to help, please get in touch with me, and check out the +project files currently available from +github.

    + +

    If you are curious what the translated book currently look like, +the updated +PDF +and +EPUB +are published on github. The HTML version is published as well, but +github hand it out with MIME type text/plain, confusing browsers, so I +saw no point in linking to that version.

    Skolelinux-intervju: Helge Tore Høyland
    -
    22nd February 2013
    -

    Etter en lang pause og travle uker har jeg endelig klart å få -samlet et nytt intervju med en av folkene i -Skolelinux-miljøet. -Denne gang er det Helge Tore Høyland, en mangeårig bidragsyter på -epostlistene og ellers i prosjektet.

    - -

    Hvem er du, og hva driver du med til daglig?

    - -

    Eg er IT-konsulent/teknikker hjå eit firma i Steinkjer med navn -Uno IT. 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 -Bjørkly skule, 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.

    - -

    Hvordan kom du i kontakt med Skolelinux-prosjektet?

    - -

    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.

    - -

    Hva er fordelene med Skolelinux slik du ser det?

    - -

    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.

    - -

    Hva er ulempene med Skolelinux slik du ser det?

    - -

    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.

    - -

    Hvilken fri programvare bruker du til daglig?

    - -

    Til dagleg bruker eg svært mange forskjellige «fri programvare» -program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla, -OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.

    - -

    Hvilken strategi tror du er den rette å bruke for å få -skoler til å ta i bruk fri programvare?

    - -

    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.

    - -

    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.

    First beta release of Debian Edu/Skolelinux based on Debian Wheezy
    +
    27th July 2013
    +

    The first wheezy based beta release of Debian Edu was wrapped up +today. This is the release announcement:

    + +

    New features for Debian Edu 7.1+edu0~b0 released +2013-07-27

    + +

    These are the release notes for for Debian Edu / Skolelinux +7.1+edu0~b0, based on Debian with codename "Wheezy".

    + +

    About Debian Edu and Skolelinux

    + +

    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. 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 +more +than 60 educational software packages and more are available from +the Debian archive, and schools can choose between KDE, Gnome, LXDE +and Xfce desktop environment.

    + +

    This is the fifth test release based on Debian Wheezy. Basically +this is an updated and slightly improved version compared to the +Squeeze release.

    + +

    ALERT: Alpha based installations should reinstall or downgrade the +versions of gosa and libpam-mklocaluser to the ones used in this beta +release.

    + +

    Software updates

    + +
      + +
    • Switched roaming workstation profiles from wicd to network-manager + for network configuration, as wicd didn't work any more.
      • +
    • Changed version numbers of patched gosa and libpam-mklocaluser + packages to make sure our locally patched versions will be replaced + by the official packages when they are released from Debian. Those + installing alpha version need to reinstall or manually downgrade gosa + and libpam-mklocaluser.
      • +
    • Added bluetooth tools to the default desktop (bluedevil, blueman).
      • +
    • Added tools for sharing the desktop on KDE (krdc, krfb).
      • +
    • Added valgrind to the default installation for easier debugging of + crash bugs.
      • + +
    + +

    Other changes

    + +
      + +
    • Fixed artwork package to work with gnome, no longer break + desktop=gnome installations.
      • +
    • Adjusted installer to now work when forced to use a proxy with the + netinst CD.
      • +
    • Fixed code detecting and setting/loading hardware specific + setup/firmware to work more robust out of the box.
      • +
    • Adjusted Kerberos setup to detect realm and server settings at + install time instead of dynamically at run time. This avoid a crash + with krb5-auth-dialog on diskless workstations without a DNS name.
      • +
    • Worked around misfeature in network-manager not calling the dhclient + exit hooks, causing automatic proxy configuration and automatic host + name setting at run time to work again.
      • +
    • Fixed feature setting the default Iceweasel start page from URL + fetched from LDAP, to allow schools to set the global default by + updating the dc=skole,dc=skolelinux,dc=no LDAP object.
      • +
    • Changed default host name on all networked machines to be unique + (generated from MAC or reverse DNS) after boot.
      • +
    • Adjusted partition sizes to make sure they are big enough.
      • + +
    + +

    Known issues

    + +
      + +
    • Grub is missing the new artwork.
      • +
    • KDE fail to understand the wpad.dat file provided, causing it to + not use the http proxy as it should.
      • +
    • Chromium also fail to use the proxy.
      • + +

    How to fix a Thinkpad X230 with a broken 180 GB SSD disk
    +
    17th July 2013
    +

    Today I switched to +my +new laptop. I've previously written about the problems I had with +my new Thinkpad X230, which was delivered with an +180 +GB Intel SSD disk with Lenovo firmware 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.

    + +

    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 ssd-setup to handle this tuning. The +source +for the ssd-setup package 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.

    + +

    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:

    + +
      + +
    • Set up cryptsetup to pass TRIM commands to the physical disk + (adding discard to /etc/crypttab)
      • + +
    • 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.
      • + +
    • Set relatime as a file system option for ext3 and ext4 file + systems.
      • + +
    • Tell swap to use TRIM commands by adding 'discard' to + /etc/fstab.
      • + +
    • Change I/O scheduler from cfq to deadline using a udev rule.
      • + +
    • Run fstrim on every ext3 and ext4 file system every night (from + cron.daily).
      • + +
    • Adjust sysctl values vm.swappiness to 1 and vm.vfs_cache_pressure + to 50 to reduce the kernel eagerness to swap out processes.

    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 +XKCD #538 for an explanation why). +Thus I concluded that adding the discard option to crypttab is the +right thing to do.

    + +

    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.

    + +

    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.

    + +

    My package do not set up tmpfs on /var/run, /var/lock and /tmp, as +this is already done by Debian Edu.

    + +

    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.

    + +

    The package should work on Ubuntu too, but I have not yet tested it +there.

    + +

    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.

    "Electronic" paper invoices - using vCard in a QR code
    -
    12th February 2013
    -

    Here in Norway, electronic invoices are spreading, and the -solution promoted -by the Norwegian government 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 -the vCard format, as -it too is supported by a lot of computer equipment these days.

    - -

    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 -ask -for donations to the Debian Edu project and thus have bank account -information publicly available) for NOK 1000.00 could have these extra -fields:

    - -

    -X-INVOICE-NUMBER:1
-X-INVOICE-AMOUNT:NOK1000.00
-X-INVOICE-KID:123412341234
-X-INVOICE-MSG:Donation to Debian Edu
-X-BANK-ACCOUNT-NUMBER:16040884339
-X-BANK-IBAN-NUMBER:NO8516040884339
-X-BANK-SWIFT-NUMBER:DNBANOKKXXX
-

    - -

    The X-BANK-ACCOUNT-NUMBER field was proposed in a stackoverflow -answer regarding -how -to put bank account information into a vCard. For payments in -Norway, either X-INVOICE-KID (payment ID) or X-INVOICE-MSG could be -used to pass on information to the seller when paying the invoice.

    - -

    The complete vCard could look like this:

    - -

    -BEGIN:VCARD
-VERSION:2.1
-ORG:SLX Debian Labs Foundation
-ADR;WORK:;;Gunnar Schjelderups vei 29D;OSLO;;0485;Norway

-EMAIL;PREF;INTERNET:sdl-styret@rt.nuug.no
-REV:20130212T095000Z
-X-INVOICE-NUMBER:1
-X-INVOICE-AMOUNT:NOK1000.00
-X-INVOICE-MSG:Donation to Debian Edu

-X-BANK-IBAN-NUMBER:NO8516040884339
-X-BANK-SWIFT-NUMBER:DNBANOKKXXX
-END:VCARD
-

    - -

    The resulting QR code created using -qrencode would look -like this, and should be readable (and thus checkable) by any smart -phone, or for example the zbar -bar code reader and feed right into the approval and accounting -system.

    - -

    - -

    The extension fields will most likely not show up in any normal -vCard reader, so those parts would have to go directly into a system -handling invoices. I am a bit unsure how vCards without name parts -are handled, but a simple test indicate that this work just fine.

    Intel SSD 520 Series 180 GB with Lenovo firmware still lock up from sustained writes
    +
    10th July 2013
    +

    A few days ago, I wrote about +the +problems I experienced with my new X230 and its SSD disk, which +was dying during installation because it is unable to cope with +sustained write. My supplier is in contact with +Lenovo, 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.

    + +

    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 +Debian Edu / Skolelinux ISO or +other large files. I look forward to hearing from my supplier with +the next proposal from Lenovo.

    + +

    The original disk is marked Intel SSD 520 Series 180 GB, +11S0C38722Z1ZNME35X1TR, ISN: CVCV321407HB180EGN, SA: G57560302, FW: +LF1i, 29MAY2013, PBA: G39779-300, LBA 351,651,888, LI P/N: 0C38722, +Pb-free 2LI, LC P/N: 16-200366, WWN: 55CD2E40002756C4, Model: +SSDSC2BW180A3L 2.5" 6Gb/s SATA SSD 180G 5V 1A, ASM P/N 0C38732, FRU +P/N 45N8295, P0C38732.

    + +

    The replacement disk is marked Intel SSD 520 Series 180 GB, +11S0C38722Z1ZNDE34N0L0, ISN: CVCV315306RK180EGN, SA: G57560-302, FW: +LF1i, 22APR2013, PBA: G39779-300, LBA 351,651,888, LI P/N: 0C38722, +Pb-free 2LI, LC P/N: 16-200366, WWN: 55CD2E40000AB69E, Model: +SSDSC2BW180A3L 2.5" 6Gb/s SATA SSD 180G 5V 1A, ASM P/N 0C38732, FRU +P/N 45N8295, P0C38732.

    + +

    The only difference is in the first number (serial number?), ISN, +SA, date and WNPP values. Mentioning all the details here in case +someone is able to use the information to find a way to identify the +failing disk among working ones (if any such working disk actually +exist).

    Sleep until morning - home automation for the kids
    -
    10th February 2013
    -

    - -

    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.

    - -

    But yesterday I came up with a method to solve this problem. It -involve home automation. A few years ago I bought a -Tellstick and RF -switches at the local Clas -Ohlson 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 -Tellstick -Net 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 -firmware -with local access 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.

    - -

    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.

    - -

    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.

    The Thinkpad is dead, long live the Thinkpad X230?
    +
    5th July 2013
    +

    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, 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 +Thinkpad X230 +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.

    + +

    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 Prisjakt, 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.

    + +

    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. :)

    + +

    Turning off the touch pad was simple. All it took was a quick +visit to the BIOS during boot it disable it.

    + +

    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 BTS +report #691427 2012-10-25 (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 +Kernel bugzilla +report #51861 2012-12-20 (Intel SSD 520 stops working under load +(SSDSC2BW180A3L in Lenovo ThinkPad T430s)). It is also reported on the +Lenovo forums, both for +T430 +2012-11-10 and for +X230 +03-20-2013. 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 +small C program +available that will lock up the hard drive after running a few +minutes by writing to a file.

    + +

    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. :)
