Bitcoin er ikke anonymt - føres Stortinget bak lyset av finansministeren?
-
22nd April 2013
-

Bitcoin er mye i mediene for -tiden. Jeg følger med via Mylder for å finne -artikler som omtaler -temaet, og takket være dette oppdaget jeg at stortingsrepresentant -Ketil Solvik-Olsen fra FrP nylig har spurt finansminister Sigbjørn -Johnsen om hans syn på Bitcoin, og -fått -svar for noen dager siden. Jeg bet meg spesielt merke til -følgende formulering fra finansministeren:

- -

-«Det er også utfordringer ved at handel med Bitcoins er uregulert og -at transaksjonene er anonyme.» -

- -

At Bitcoin er anonymt er en myte som spres av både journalister og -andre, så det er ikke veldig overraskende at også finansministeren har -gått på limpinnen. Det er dog litt rart, da jeg håper at -finansdepartementet ikke baserer seg på rykter og myter når de -besvarer Stortinget. Men du trenger ikke bare tro på meg som kilde -til påstanden om at Bitcoin ikke er anonymt. Sondre Rønjom har -via Sikkerhetsbloggen -hos Nasjonal Sikkerhetsmyndighet uttalt følgende:

- -

-«At [bitcoin] i utgangspunktet -ikke er anonymt, -kommer kanskje som en overraskelse på mange.» -

- -

Enhver bevegelse av Bitcoin er offentlig tilgjengelig for alle på -Internet, og en må legge svært mye innsats inn hvis en skal hindre at -nettverksanalyse av transaksjonsloggene kan brukes til å identifisere -brukerne. F.eks. kan en enkelt se hva jeg har mottatt til min -offentliggjorte mottaksadresse ved å besøke blockexplorer og slå opp -adressen -15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b. -Det virker dermed på meg ganske klart at å påstå at -Bitcoin-transaksjoner er anonyme strengt tatt er å føre Stortinget bak -lyset.

- -

Finansministeren er ikke den eneste som har latt seg forlede av -medieomtalen. I spørsmålet fra Hr. Solvik-Olseb skriver han at «For -noen dager siden kom den første bitcoin-minibanken på Kypros», hvilket -så vidt jeg har klart å finne ut ikke er riktig. Det er annonsert -planer om en slik minibank (fra -BitcoinATM), men jeg finner -intet tegn til at en slik minibank er utplassert noe sted.

- -

Som vanlig, hvis du bruker Bitcoin og ønsker å vise din støtte til -mine aktiviteter, så setter jeg pris på Bitcoin-donasjoner til min -adresse -15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b.

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. +
  3. Boot from it, either as CD or USB stick.
  4. +
  5. 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
  6. + +
  7. Answer the few language/region/password questions and pick disk to +install on.
  8. + +
  9. When the installation is finished and the machine have rebooted a +few times, your Freedombox is ready for testing.
  10. + +
+ +

Raspberry Pi Raspbian

+ +
    + +
  1. Fetch a Raspbian SD card image, create SD card.
  2. +
  3. Boot from SD card, extend file system to fill the card completely.
  4. +
  5. Log in and add this to /etc/sources.list:

    +
    +deb http://www.reinholdtsen.name/freedombox wheezy main
    +
  6. +
  7. 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
    +
  8. +
  9. Reboot into your freshly created Freedombox.
  10. + +
+ +

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'.

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:

The second wheezy based beta release of Debian Edu was wrapped up +today, slightly delayed because of some bugs in the initial Windows +integration fixes . This is the release announcement:

+ +

New features for Debian Edu 7.1+edu0~b1 released 2013-08-22

+ +

These are the release notes for Debian Edu / Skolelinux +7.1+edu0~b1, 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 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.

    For en stund tilbake gikk nyheten om -Sandy -Island, en øy som var dukket opp på noen kart, men som ikke var -synlig når en sjekket den på satellittbilder. Dagbladet meldte for -eksempel at -«denne -øya finnes på kart, men ikke i virkeligheten». Noe senere begynte -jeg å lese -historier -om Ruffen til mine barn. Dette er historier om sjøormen Ruffen -skapt av Tor Åge Bringsværd, som starter med følgende beskrivelse:

    - -

    -«Langt ute i havet ligger en mystisk øy. Den er bare synlig hver -tirsdag og fredag. Derfor står den ikke på noe kart. På denne øya -ligger et slott, og i slottet bor en gammel, fin sjøormfamilie.» -

    - -

    Det virker åpenbart at Hr. Bringsværd tok feil når han trodde den -ikke var på noe kart, og at noen tydeligvis har vært i nærheten en -tirsdag eller en fredag og fått den med på et kart, mens -satellittbildene er tatt på noen av de fem andre dagene i uka og -dermed ikke ser øya. :)

    I følge -en -senere artikkel i Dagbladet hevder Shaun Higgins, en forsker fra -New Zealand, at et hvalfangstskip fra 1876 er opprinnelsen til at -spøkelsesøya i det hele tatt havnet på kartet. Det fremgår ikke fra -historien hvilken ukedag de var innom.

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.

    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.

    Tor Åge Bringsværd-novelle om IT og overvåkning fra -informasjonsteknologiens spedbarndom får nytt liv

    - -

    Elektronisk Forpost Norge (EFN) er veldig glad for anledningen til -å nyutgi Tor Åge Bringsværds novelle Kodémus i digitalt format for nye -(og gamle) generasjoner. Novellen ble skrevet så tidlig som vinteren -1968, og første gang trykt i novellesamlingen Probok på Gyldendal -samme år.

    - -

    Informasjonsteknologi spiller en sentral rolle i Kodémus, og det er -spennende å sammenligne beskrivelsen av IT fra 1968 med dagens IT i -2013. Forskjellene er mange -- men det er jammen likhetene også. Ikke -minst det at idag går jo nesten alle rundt med lillebrødre på seg!

    - -

    "Riktignok er det ikke påbudt å ha mobil," sier Thomas Gramstad, -leder i EFN. "Men vi holder på å lage et samfunn der det blir så -upraktisk eller tungvint å ikke ha det, at man i praksis ikke slipper -unna. Og disse lillebrødrene sladrer hele tiden til staten (og til -mange andre) om hvor vi er, hva vi gjør, hva vi bryr oss om, hva vi -liker..."

    - -

    Det at Kodémus åpenbart er skrevet i en annen tid med en annen type -IT og likevel virker så relevant idag, er i seg selv et hardtslående -tankekors.

    - -

    Tross sitt IT-tema fantes ikke Kodémus i elektronisk form, og -frivillige i EFN har skannet inn, OCR-tolket og korrekturlest -novellen, og deretter kodet den i en rekke digitale formater.

    - -

    Forfatteren har gitt tillatelse til publisering av Kodémus under ny -lisens, og novellen utgis av EFN med en Creative Commons (CC) -fribrukslisens (nærmere bestemt lisensen CC-BY-NC-ND). For leserne -eller brukerne innebærer dette at de får en klar og standardisert -beskjed om hvilke rettigheter de har til å dele novellen videre med -andre. For forfatteren innebærer dette økt synlighet og -tilgjengelighet for verket, slik at det ikke blir glemt, da -søkemotorer og nettlesere inneholder egne søkevalg for CC-lisenser, og -mange brukere søker etter verk som de vet de kan dele og bruke på -lovlig vis.

    - -

    EFN oppfordrer andre forfattere om å gi ut sine gamle tekster med -en fribrukslisens, slik at tekstene ikke blir glemt og for å stimulere -lovlig deling på nettet. EFN kan være behjelpelig med digitalisering -og utlegging på nett, i den grad det finnes kapasitet blant EFNs -medlemmer til dette. Vi mener at nyutgivelser av tekster under frie -lisenser kan øke interessen rundt forfatterskapet, og vil gjerne bidra -til dette.

    - -

    EFN utgir og deler med dette en novelle fra den digitale -informasjonsteknologiens tidligste barndom. En novelle som fortsatt er -full av vitalitet og aktualitet, og som derfor kan bidra til, og gi -ettertanke i dagens debatter om IT, personvern, overvåkning og -individets frihet og integritet.

    - -

    Du finner novellen her: -
    http://efn.no/kodemus/

    - -

    i flere forskjellige formater, for ulike plattformer. Per idag -finnes novellen i disse formatene: EPUB, MOBI, XML, HTML, PDF og -txt. Det kan bli flere formater senere, og evt. frivillige -bidragsytere til dette er velkommen.

    Jeg håper flere forfattere ser verdien av å gjøre kulturen -tilgjengelig for flere, og slår følge med Hr. Bringsværd i å gi ut -sine verker med bruksvilkår med færre bruksbegrensinger enn -opphavsretten legger opp til. Selv om jeg gjerne skulle sett at han -hadde brukt en Creative Commons-lisens som tillot avledede verker og -kommersiell bruk.

    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.
    • + +

    Would you like to help the environment and save money at the same -time, without much sacrifice? A small step could be to change the -font you use when printing.

    - -

    Three years ago, -Ars -Technica reported how the University of Wisconsin-Green Bay -changed their default front from -Arial to -Century -Gothic to save money. The Century Gothic font uses 30% less toner -than Arial to print the same text. In other word, you could cut your -toner costs by 30% (or actually, increase your toner supply life time -by more than 30%), by simply changing the default font used in your -prints.

    - -

    But it is not quite obvious how much one will save by switching. -The University of Wisconsin-Green Bay said it used $100,000 per year -on ink and toner cartridges, according to -a report from -TwinCities.com, and expected to save between $5,000 and $10,000 -per year by asking staff and students to use a different font. Not -all PDFs and documents are created internally, and those from external -sources will most likely still use a different font. Also, the -Century Gothic font is slightly wider than Arial, and thus might use -more sheets of paper to print the same text, so the total saving -depend on the documents printed.

    - -

    But it is definitely something to consider, if you want to reduce -the amount of trash, decrease the amount of toner used in the world, -and save some money in the process.

    - -

    Update 2013-04-10: If you want to know how much ink/toner could be -saved when switching between fonts, Inkfarm got a -service to calculate the -difference between font pairs. They also -recommend -which fonts to use to save ink. Check it out. :) While updating -this blog post, I also came across a blog post from InkCloners, -listing -the fonts they recommend, with Centory Gothic at the top.

    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.

    A few days ago, during a discussion in -EFN about interesting books to read -about copyright and the data retention directive, a suggestion to read -the 1968 short story Kodémus by -Tore Åge Bringsværd -came up. The text was only available in old paper books, and thus not -easily available for current and future generations. Some of the -people participating in the discussion contacted the author, and -reported back 2013-03-19 that the author was OK with releasing the -short story using a Creative -Commons license. The text was quickly scanned and OCR-ed, and we -were ready to start on the editing and typesetting.

    - -

    As I already had some experience formatting text in my project to -provide a Norwegian version of the Free Culture book by Lawrence -Lessig, I chipped in and set up a -DocBook processing framework to -generate PDF, HTML and EPUB version of the short story. The tools to -transform DocBook to different formats are already in my Linux -distribution of choice, Debian, so -all I had to do was to use the -dblatex, -dbtoepub -and xmlto tools to do the -conversion. After a few days, we decided to replace dblatex with -xsltproc/fop (aka -docbook-xsl), -to get the copyright information to show up in the PDF and to get a -nicer <variablelist> typesetting, but that is just a minor -technical detail.

    - -

    There were a few challenges, of course. We want to typeset the -short story to look like the original, and that require fairly good -control over the layout. The original short story have three -parts/scenes separated by a single horizontally centred star (*), and -the paragraphs do not contain only flowing text, but dialogs and text -that started on a new line in the middle of the paragraph.

    - -

    I initially solved the first challenge by using a paragraph with a -single star in it, ie <para>*</para>, but it made sure a -placeholder indicated where the scene shifted. This did not look too -good without the centring. The next approach was to create a new -preprocessor directive <?newscene?>, mapping to "<hr/>" -for HTML and "<fo:block text-align="center"><fo:leader -leader-pattern="rule" rule-thickness="0.5pt"/></fo:block>" -for FO/PDF output (did not try to implement this in dblatex, as we had -switched at this time). The HTML XSL file looked like this:

    - -

    -<?xml version='1.0'?> 
    -<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'>
    -  <xsl:template match="processing-instruction('newscene')">
    -    <hr/>
    -  </xsl:template>
    -</xsl:stylesheet> 
    -

    - -

    And the FO/PDF XSL file looked like this:

    - -

    -<?xml version='1.0'?> 
    -<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'>
    -  <xsl:template match="processing-instruction('newscene')">
    -    <fo:block text-align="center">
    -      <fo:leader leader-pattern="rule" rule-thickness="0.5pt"/>
    -    </fo:block>
    -  </xsl:template>
    -</xsl:stylesheet> 
    -

    - -

    Finally, I came across the <bridgehead> tag, which seem to be -a good fit for the task at hand, and I replaced <?newscene?> -with <bridgehead>*</bridgehead>. It isn't centred, but we -can fix it with some XSL rule if the current visual layout isn't -enough.

    - -

    I did not find a good DocBook compliant way to solve the -linebreak/paragraph challenge, so I ended up creating a new processor -directive <?linebreak?>, mapping to <br/> in HTML, and -<fo:block/> in FO/PDF. I suspect there are better ways to do -this, and welcome ideas and patches on github. The HTML XSL file now -look like this:

    - -

    -<?xml version='1.0'?> 
    -<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'>
    -  <xsl:template match="processing-instruction('linebreak)">
    -    <br/>
    -  </xsl:template>
    -</xsl:stylesheet> 
    -

    - -

    And the FO/PDF XSL file looked like this:

    - -

    -<?xml version='1.0'?> 
    -<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'
    -  xmlns:fo="http://www.w3.org/1999/XSL/Format">
    -  <xsl:template match="processing-instruction('linebreak)">
    -    <fo:block/>
    -  </xsl:template>
    -</xsl:stylesheet> 
    -

    - -

    One unsolved challenge is our wish to expose different ISBN numbers -per publication format, while keeping all of them in some conditional -structure in the DocBook source. No idea how to do this, so we ended -up listing all the ISBN numbers next to their format in the colophon -page.

    - -

    If you want to check out the finished result, check out the -source repository at -github -(future/new/official -repository). We expect it to be ready and announced in a few -days.

    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.

    I -siste -høring om -referansekatalogen -for IT-standarder i offentlig sektor, med høringsfrist 2012-09-30 -(DIFI-sak 2012/498), ble det foreslått å fjerne ODF som obligatorisk -standard når en publiserte dokumenter som skulle kunne redigeres -videre av mottaker. NUUG og andre protesterte på forslaget, som er et -langt steg tilbake når det gjelder å sikre like rettigheter for alle -når en kommuniserer med det offentlige. For noen dager siden ble jeg -oppmerksom på at Direktoratet for forvaltning og IKT (DIFI) og -Fornyings-,administrasjons- og kirkedepartementet (FAD) har -konkludert, og oversendt forslag til regjeringen i saken. FADs -dokument -2012/2168-8, -«Utkast til endring av standardiseringsforskriften» datert 2013-02-06 -har følgende triste oppsummering fra høringen i saken:

    - -

    -Det kom noen innvendinger på forslaget om å fjerne ODF som -obligatorisk standard for redigerbare dokumenter. Innvendingene har -ikke blitt ilagt avgjørende vekt. -

    - -

    Ved å fjerne ODF som obligatorisk format ved publisering av -redigerbare dokumenter setter en Norge tiår tilbake. Det som vil skje -er at offentlige etater går tilbake til kun å publisere dokumenter på -et av de mange formatene til Microsoft Office, og alle som ikke -aksepterer bruksvilkårene til Microsoft eller ikke har råd til å bruke -penger på å få tilgang til Microsoft Office må igjen basere seg på -verktøy fra utviklerne som er avhengig av å reversutvikle disse -formatene. I og med at ISO-spesifikasjonen for OOXML ikke komplett og -korrekt spesifiserer formatene til MS Office (men er nyttige å titte i -når en reversutvikler), er en tilbake til en situasjon der en ikke har -en -fri og åpen standard å forholde seg til, men i stedet må springe -etter Microsoft. Alle andre leverandører enn Microsoft vil dermed ha -en seriøs ulempe. Det er som å fjerne krav om bruk av meter som -måleenhet, og heretter aksepterer alle måleenheter som like gyldige, -når en vet at den mest brukte enheten vil være armlengden til Steve -Ballmer slik Microsoft måler den.

    - -

    Jeg er ikke sikker på om forslaget er vedtatt av regjeringen ennå. -Kristian Bergem hos DIFI nevnte på et møte forrige tirsdag at han -trodde det var vedtatt i statsråd 8. mars, men jeg har ikke klart å -finne en skriftlig kilde på regjeringen.no som bekrefter dette. -Kanskje det ennå ikke er for sent...

    Jeg ba i forrige uke om innsyn i dokument 6, 7 og 8 i FAD-saken, og -har i dag fått innsyn i dokument 7 og 8. Ble nektet innsyn i -dokumentet med tittelen «Oppsummering av høring om endringer i -forskrift om IT-standarder i offentlig forvaltning» med hjemmel i -off. lovens §15.1, så det er vanskelig å vite hvordan argumentene fra -høringen ble mottatt og forstått av saksbehandleren hos DIFI.

    Via -twitter -I just discovered that Pcwizz have -done a video -review on Youtube of Skolelinux -/ Debian Edu version 6. He installed the standalone profile and -the video show a walk-through of of the menu content, demonstration of -a few programs and his view of our distribution.

    - -

    There is also some really nice quotes (transcribed by me, might -have heard wrong). While looking thought the Graphics menu:

    - -
    -"Basically everything you ever need in a school environment." -
    - -

    And as a general evaluation of the entire distribution:

    - -
    -"So, yeah, a bit bloated. It kept all the Debian stuff in there, just -to keep it nice and GNU. So, I do not want to go on about it, but -lets give it 7 out of 10. I am not going to use it. That is because -I am not deploying a school network. There may be some mythical -feature to help you deploy Skolelinux on a school network." -
    - -

    To bad he did not test the server profile, and discovered the PXE -installation option. It make it possible to install only the main -server from CD, and the rest of the machines via the net, and might be -considered the mythical feature he talk about. :)

    - -

    While looking through the menus, there is also this funny comment -about the part of the K menu generated from the Debian menu subsystem: - -

    -"[The K menu] have a special Debian section for software that no-one -is going to look at, because it contain lots of junky stuff that you -actually don't need in the education distribution, but have just been -included because it isn't stripped out for some reason." -
    - -

    I guess it is yet another argument for merging the Debian menu and -Gnome/KDE desktop menu entries into -one -consistent menu system instead of two incomplete and partly -inconsistent menu systems.

    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. :)
