Using modalias info to find packages handling my hardware
-
15th January 2013
-

Yesterday, I wrote about the -modalias -values provided by the Linux kernel following my hope for -better -dongle support in Debian. Using this knowledge, I have tested how -modalias values attached to package names can be used to map packages -to hardware. This allow the system to look up and suggest relevant -packages when I plug in some new hardware into my machine, and replace -discover and discover-data as the database used to map hardware to -packages.

- -

I create a modaliases file with entries like the following, -containing package name, kernel module name (if relevant, otherwise -the package name) and globs matching the relevant hardware -modalias.

- -

-Package: package-name -
Modaliases: module(modaliasglob, modaliasglob, modaliasglob)

-

- -

It is fairly trivial to write code to find the relevant packages -for a given modalias value using this file.

- -

An entry like this would suggest the video and picture application -cheese for many USB web cameras (interface bus class 0E01):

- -

-Package: cheese -
Modaliases: cheese(usb:v*p*d*dc*dsc*dp*ic0Eisc01ip*)

-

- -

An entry like this would suggest the pcmciautils package when a -CardBus bridge (bus class 0607) PCI device is present:

- -

-Package: pcmciautils -
Modaliases: pcmciautils(pci:v*d*sv*sd*bc06sc07i*) -

- -

An entry like this would suggest the package colorhug-client when -plugging in a ColorHug with USB IDs 04D8:F8DA:

- -

-Package: colorhug-client -
Modaliases: colorhug-client(usb:v04D8pF8DAd*)

-

- -

I believe the format is compatible with the format of the Packages -file in the Debian archive. Ubuntu already uses their Packages file -to store their mappings from packages to hardware.

- -

By adding a XB-Modaliases: header in debian/control, any .deb can -announce the hardware it support in a way my prototype understand. -This allow those publishing packages in an APT source outside the -Debian archive as well as those backporting packages to make sure the -hardware mapping are included in the package meta information. I've -tested such header in the pymissile package, and its modalias mapping -is working as it should with my prototype. It even made it to Ubuntu -Raring.

- -

To test if it was possible to look up supported hardware using only -the shell tools available in the Debian installer, I wrote a shell -implementation of the lookup code. The idea is to create files for -each modalias and let the shell do the matching. Please check out and -try the -hw-support-lookup -shell script. It run without any extra dependencies and fetch the -hardware mappings from the Debian archive and the subversion -repository where I currently work on my prototype.

- -

When I use it on a machine with a yubikey inserted, it suggest to -install yubikey-personalization:

- -

-% ./hw-support-lookup -
yubikey-personalization -
% -

- -

When I run it on my Thinkpad X40 with a PCMCIA/CardBus slot, it -propose to install the pcmciautils package:

- -

-% ./hw-support-lookup -
pcmciautils -
% -

- -

If you know of any hardware-package mapping that should be added to -my -database, please tell me about it.

- -

It could be possible to generate several of the mappings between -packages and hardware. One source would be to look at packages with -kernel modules, ie packages with *.ko files in /lib/modules/, and -extract their modalias information. Another would be to look at -packages with udev rules, ie packages with files in -/lib/udev/rules.d/, and extract their vendor/model information to -generate a modalias matching rule. I have not tested any of these to -see if it work.

- -

If you want to help implementing a system to let us propose what -packages to install when new hardware is plugged into a Debian -machine, please send me an email or talk to me on -#debian-devel.

Modalias strings - a practical way to map "stuff" to hardware
-
14th January 2013
-

While looking into how to look up Debian packages based on hardware -information, to find the packages that support a given piece of -hardware, I refreshed my memory regarding modalias values, and decided -to document the details. Here are my findings so far, also available -in -the -Debian Edu subversion repository: - -

Modalias decoded

- -

This document try to explain what the different types of modalias -values stands for. It is in part based on information from -<URL: https://wiki.archlinux.org/index.php/Modalias >, -<URL: http://unix.stackexchange.com/questions/26132/how-to-assign-usb-driver-to-device >, -<URL: http://code.metager.de/source/history/linux/stable/scripts/mod/file2alias.c > and -<URL: http://cvs.savannah.gnu.org/viewvc/dmidecode/dmidecode.c?root=dmidecode&view=markup >. - -

The modalias entries for a given Linux machine can be found using -this shell script:

- -
-cat $(find /sys -name modalias) | sort -u
-
- -

The supported modalias globs for a given kernel module can be found -using modinfo:

- -
-% /sbin/modinfo psmouse | grep alias:
-alias:          serio:ty05pr*id*ex*
-alias:          serio:ty01pr*id*ex*
-%
-
- -

PCI subtype

- -

A typical PCI entry can look like this. This is an Intel Host -Bridge memory controller:

- -

-pci:v00008086d00002770sv00001028sd000001ADbc06sc00i00 -

- -

This represent these values:

- -
- v   00008086  (vendor)
- d   00002770  (device)
- sv  00001028  (subvendor)
- sd  000001AD  (subdevice)
- bc  06        (bus class)
- sc  00        (bus subclass)
- i   00        (interface)
-
- -

The vendor/device values are the same values outputted from 'lspci --n' as 8086:2770. The bus class/subclass is also shown by lspci as -0600. The 0600 class is a host bridge. Other useful bus values are -0300 (VGA compatible card) and 0200 (Ethernet controller).

- -

Not sure how to figure out the interface value, nor what it -means.

- -

USB subtype

- -

Some typical USB entries can look like this. This is an internal -USB hub in a laptop:

- -

-usb:v1D6Bp0001d0206dc09dsc00dp00ic09isc00ip00 -

Here is the values included in this alias:

This is the release notes for for Debian Edu / Skolelinux 7.0.0 edu +alpha1, 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. Immediatly after installation a school +server running all services needed for a school network is set up just +waiting for users and machines being added via GOsa², a comfortable +Web-UI. A netbooting environment is prepared using PXE, so after +initial installation of the main server from CD, DVD or USB stick all +other machines can be installed via the network.

+ +

This is the first test release based on Wheezy (which currently is +not released yet). Basically this is an updated and slightly improved +version compared to the Squeeze release.

+ +

Software updates

+
    +
  • Install freemind (0.9.0) by default, and stop installing vym by + default.
  • +
  • Install chromium (26.0.1410.43) by default.
  • +
  • Install goplay (0.5-1.1) to make golearn available by default.
  • +
  • Updated support for Japanese input methods, now based on + ibus-anthy.

    The 0900 device class/subclass means hub. Some times the relevant -class is in the interface class section. For a simple USB web camera, -these alias entries show up:

    +
  • Switched default file system from ext3 to ext4 for speed and + reliability improvements.
  • +
  • Got rid of unwanted winbind daemon and PAM setup activated because + of 706434.
  • +
  • Extended and improved the testsuite tests to detect more possible + problems.
  • +
  • Corrected proxy handling to not set http_proxy to a bogus + direct:// URL.
  • +
  • Corrected proxy setup for diskless workstations.
  • +
  • Corrected PXE setup to use our updated udebs during installation.
  • +
  • Made installation handling of low entropy level more robust.
  • +
  • Create larger partitions for Roaming workstations and Thin client + servers, to make room for all the software installed.

    -

    Interface class 0E01 is video control, 0E02 is video streaming (aka -camera), 0101 is audio control device and 0102 is audio streaming (aka -microphone). Thus this is a camera with microphone included.

    +
  • IP resolution for the local hostname give useless IPv6 address + (705900). Only install + libnss-myhostname on roaming workstations until it is fixed.
  • +
  • DVD images are not yet ready.
  • +
  • No mass import of user account data in GOsa (ldif or csv) + available yet (698840).
  • +
  • Missing artwork for the KDE desktop (and probably a few others).
  • +
  • KDE Debian submenu lacks icons.
  • +
  • LXDE menu lacks entry for changing GOsa password + (website). Installing gosa-desktop will be an option.
  • +
  • Backup configuration via web interface is impossible due to + password submission problem + (700257).

SerIO subtype

- -

This type is used for PS/2 mouse plugs. One example is from my -test machine:

- -
-  ty  01  (type)
-  pr  00  (prototype)
-  id  00  (id)
-  ex  00  (extra)
-
- -

This type is supported by the psmouse driver. I am not sure what -the valid values are.

- -

Other subtypes

- -

There are heaps of other modalias subtypes according to -file2alias.c. There is the rest of the list from that source: amba, -ap, bcma, ccw, css, eisa, hid, i2c, ieee1394, input, ipack, isapnp, -mdio, of, parisc, pcmcia, platform, scsi, sdio, spi, ssb, vio, virtio, -vmbus, x86cpu and zorro. I did not spend time documenting all of -these, as they do not seem relevant for my intended use with mapping -hardware to packages when new stuff is inserted during run time.

- -

Looking up kernel modules using modalias values

- -

To check which kernel modules provide support for a given modalias, -one can use the following shell script:

- -
-  for id in $(cat $(find /sys -name modalias)|sort -u); do \
-    echo "$id" ; \
-    /sbin/modprobe --show-depends "$id"|sed 's/^/  /' ; \
-  done
-
- -

The output can look like this (only the first few entries as the -list is very long on my test machine):

- -
-  acpi:ACPI0003:
-    insmod /lib/modules/2.6.32-5-686/kernel/drivers/acpi/ac.ko

As part of my investigation on how to improve the support in Debian -for hardware dongles, I dug up my old Mark and Spencer USB Rocket -Launcher and updated the Debian package -pymissile to make -sure udev will fix the device permissions when it is plugged in. I -also added a "Modaliases" header to test it in the Debian archive and -hopefully make the package be proposed by jockey in Ubuntu when a user -plug in his rocket launcher. In the process I moved the source to a -git repository under collab-maint, to make it easier for any DD to -contribute. Upstream -is not very active, but the software still work for me even after five -years of relative silence. The new git repository is not listed in -the uploaded package yet, because I want to test the other changes a -bit more before I upload the new version.

One thing that annoys me with Debian and Linux distributions in -general, is that there is a great package management system with the -ability to automatically install software packages by downloading them -from the distribution mirrors, but no way to get it to automatically -install the packages I need to use the hardware I plug into my -machine. Even if the package to use it is easily available from the -Linux distribution. When I plug in a LEGO Mindstorms NXT, it could -suggest to automatically install the python-nxt, nbc and t2n packages -I need to talk to it. When I plug in a Yubikey, it could propose the -yubikey-personalization package. The information required to do this -is available, but no-one have pulled all the pieces together.

- -

Some years ago, I proposed to -use -the discover subsystem to implement this. The idea is fairly -simple: - -

    - -
  • Add a desktop entry in /usr/share/autostart/ pointing to a program - starting when a user log in.
  • - -
  • Set this program up to listen for kernel events emitted when new - hardware is inserted into the computer.
  • - -
  • When new hardware is inserted, look up the hardware ID in a - database mapping to packages, and take note of any non-installed - packages.
  • - -
  • Show a message to the user proposing to install the discovered - package, and make it easy to install it.
  • - -
- -

I am not sure what the best way to implement this is, but my -initial idea was to use dbus events to discover new hardware, the -discover database to find packages and -PackageKit to install -packages.

- -

Yesterday, I found time to try to implement this idea, and the -draft package is now checked into -the -Debian Edu subversion repository. In the process, I updated the -discover-data -package to map the USB ids of LEGO Mindstorms and Yubikey devices to -the relevant packages in Debian, and uploaded a new version -2.2013.01.09 to unstable. I also discovered that the current -discover -package in Debian no longer discovered any USB devices, because -/proc/bus/usb/devices is no longer present. I ported it to use -libusb as a fall back option to get it working. The fixed package -version 2.1.2-6 is now in experimental (didn't upload it to unstable -because of the freeze).

- -

With this prototype in place, I can insert my Yubikey, and get this -desktop notification to show up (only once, the first time it is -inserted):

- -

- -

For this prototype to be really useful, some way to automatically -install the proposed packages by pressing the "Please install -program(s)" button should to be implemented.

- -

If this idea seem useful to you, and you want to help make it -happen, please help me update the discover-data database with mappings -from hardware to Debian packages. Check if 'discover-pkginstall -l' -list the package you would like to have installed when a given -hardware device is inserted into your computer, and report bugs using -reportbug if it isn't. Or, if you know of a better way to provide -such mapping, please let me know.

- -

This prototype need more work, and there are several questions that -should be considered before it is ready for production use. Is dbus -the correct way to detect new hardware? At the moment I look for HAL -dbus events on the system bus, because that is the events I could see -on my Debian Squeeze KDE desktop. Are there better events to use? -How should the user be notified? Is the desktop notification -mechanism the best option, or should the background daemon raise a -popup instead? How should packages be installed? When should they -not be installed?

- -

If you want to help getting such feature implemented in Debian, -please send me an email. :)

Notatet forteller at Narvik ville måtte betalt minst 9 millioner +for å gå over til Windows på skolene.

The new debian release contain heaps of new stuff, and one program +in particular make me very happy to see included. The +Scratch program, made famous by +the Teach kids code movement, is +included for the first time.

1st May 2013
+

For noen uker siden, innen fristen 2013-04-15, leverte jeg og +Morten Kjelkenes vårt bidrag til +DIFIs apps4norge-konkurranse +under lagnavnet NUUGs tannlegeteam. +Vi leverte følgende i idé-kategorien:

+ +
+ +

Tittel: Stikk innom tannlegen

+ +

+ +

Beskrivelse:

+ +

Idéen + +

Gjøre det enklere å finne en tannlege som er praktisk for deg, der +pris og reisetid med kollektivt, til fots eller med bil er tatt med i +beregningen, ved å oppgi hvor en bor og jobber, og få forslag til +tannleger både i nærheten og på veien mellom disse stedene.

+ +

Brukeren oppgir hjemmeadresse og jobbadresse, og kanskje også +barnehage. Så kan en også oppgi egen timelønn (for å beregne taps +arbeidsfortjeneste) og om en reiser med kollektivt, til fots eller +kjører bil. Så trykker en søk, og får opp en todelt side med kart og +tekstliste. I kartdelen vises aktuelle tannleger (for eksempel maks +7), og i tekstdelen er de samme tannlegene listet opp, med pris og +reisetid for kollektivtransport, og pris pluss reisekostnad hvis en +reiser med bil. En kan endre sorteringsrekkefølge for listen ved å +trykke på aktuell kolonne, og velge om en skal sortere på pris, +reisetid eller totalkostnad. Kun tannleger som tar imot nye kunder tas +i utganspunktet med i listen. Når brukeren trykker med musa en +tannlegemarkør på kartet kommer det en popup med detaljer om +tannlegen, den samme informasjonen som finnes i listen under kartet, +og lenke til mer informasjon om tannlegen.

+ +

For hvert enkelt tannlegekontor er det tilgjengelig en +informasjonsside med adresse, hjemmesideurl, telefonnummer, lenke til +side for å finne reisebeskrivelse, åpningstider, etc.

    I was happy to discover a few days ago that the -Skolelinux / Debian Edu -project also this year received a Christmas present from Another -Agency in Trondheim. NOK 1000,- showed up on our donation account -December 24th. I want to express our thanks for this very welcome -present. As the Debian Edu / Skolelinux project is very short on -funding these days, and thus lack the money to do regular developer -gatherings, this donation was most welcome. One developer gathering -cost around NOK 15 000,-, so we need quite a lot more to keep the -development pace we want. Thus, I hope their example this year is -followed by many others. :)

    Bitcoin, the digital -decentralised "currency" that allow people to transfer bitcoins -between each other with minimal overhead, is a very interesting -experiment. And as I wrote a few days ago, the bitcoin situation in -Debian is about to improve a bit. -The new debian source -package (version 0.7.2-2) was uploaded yesterday, and is waiting -in the NEW queue -for one of the ftpmasters to approve the new bitcoin-qt package -name.

    - -

    And thanks to the great work of Jonas and the rest of the bitcoin -team in Debian, you can easily test the package in Debian Squeeze -using the following steps to get a set of working packages:

    - -
    -git clone git://git.debian.org/git/collab-maint/bitcoin
    -cd bitcoin
    -DEB_MAINTAINER_MODE=1 DEB_BUILD_OPTIONS=noupnp fakeroot debian/rules clean
    -DEB_BUILD_OPTIONS=noupnp git-buildpackage --git-ignore-new
    -
    - -

    You might have to install some build dependencies as well. The -list of commands should give you two packages, bitcoind and -bitcoin-qt, ready for use in a Squeeze environment. Note that the -client will download the complete set of bitcoin "blocks", which need -around 5.6 GiB of data on my machine at the moment. Make sure your -~/.bitcoin/ directory have lots of spare room if you want to download -all the blocks. The client will warn if the disk is getting full, so -there is not really a problem if you got too little room, but you will -not be able to get all the features out of the client.

    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-Olsen 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.

    It has been a while since I wrote about -bitcoin, the decentralised -peer-to-peer based crypto-currency, and the reason is simply that I -have been busy elsewhere. But two days ago, I started looking at the -state of bitcoin in -Debian again to try to recover my old bitcoin wallet. The package -is now maintained by a -team of -people, and the grunt work had already been done by this team. We -owe a huge thank you to all these team members. :) -But I was sad to discover that the bitcoin client is missing in -Wheezy. It is only available in Sid (and an outdated client from -backports). The client had several RC bugs registered in BTS blocking -it from entering testing. To try to help the team and improve the -situation, I spent some time providing patches and triaging the bug -reports. I also had a look at the bitcoin package available from Matt -Corallo in a -PPA for -Ubuntu, and moved the useful pieces from that version into the -Debian package.

    - -

    After checking with the main package maintainer Jonas Smedegaard on -IRC, I pushed several patches into the collab-maint git repository to -improve the package. It now contains fixes for the RC issues (not from -me, but fixed by Scott Howard), build rules for a Qt GUI client -package, konqueror support for the bitcoin: URI and bash completion -setup. As I work on Debian Squeeze, I also created -a -patch to backport the latest version. Jonas is going to look at -it and try to integrate it into the git repository before uploading a -new version to unstable. - -

    I would very much like bitcoin to succeed, to get rid of the -centralized control currently exercised in the monetary system. I -find it completely unacceptable that the USA government is collecting -transaction data for almost all international money transfers (most are done in USD and transaction logs shipped to the spooks), and -that the major credit card companies can block legal money -transactions to Wikileaks. But for bitcoin to succeed, more people -need to use bitcoins, and more people need to accept bitcoins when -they sell products and services. Improving the bitcoin support in -Debian is a small step in the right direction, but not enough. -Unfortunately the user experience when browsing the web and wanting to -pay with bitcoin is still not very good. The bitcoin: URI is a step -in the right direction, but need to work in most or every browser in -use. Also the bitcoin-qt client is too heavy to fire up to do a -quick transaction. I believe there are other clients available, but -have not tested them.

    - -

    My -experiment -with bitcoins showed that at least some of my readers use bitcoin. -I received 20.15 BTC so far on the address I provided in my blog two -years ago, as can be -seen -on the blockexplorer service. Thank you everyone for your -donation. The blockexplorer service demonstrates quite well that -bitcoin is not quite anonymous and untracked. :) I wonder if the -number of users have gone up since then. If you use bitcoin and want -to show your support of my activity, please send Bitcoin donations to -the same address as last time, -15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b.

    Jeg ble overrasket over å se at Piratpartiet i -Aftenposten -er referert på følgende:

    + +
    9th April 2013
    +

    For cirka en måned siden +ba +jeg om begrunnelse på nektet innsyn i dokumenter om +standardkatalogen fra Fornyingsdepartementet. I dag fikk jeg svar fra +Fornyingsdepartementet, og tilgang til dokumentene. Jeg fikk både +innsyn i vedlegg sendt fra DIFI, og også innsyn i et notat brukt +internt i Fornyingsdepartementet:

    -
    -Når det gjelder retten til opphavsrett for kulturproduktene, mener -Piratpartiet av levetid + 14 år er tilfredsstillende. -
    + -

    Det virker dermed på meg som om Piratpartiet allerede har gjort -retrett fra sin beundringsverdige holdning om at det holdt med 14 års -total vernetid, til sin nye som tar utgangspunkt i levetiden til -opphavspersonen. Jeg håper det baserer seg på en misforståelse hos -piratlederen som blir korrigert tilbake til 14 års total vernetid før -partiet stiller til valg.

    - -

    Hvis du lurer på hvilke problemer lang vernetid bringer med seg, -anbefaler jeg å lese boken Free -Culture av Lawrence Lessig. Jeg og en liten gruppe andre er igang -med å -oversette -boken til bokmål og tar gjerne imot hjelp med oversettelse og -korrekturlesing.

    - -

    Oppdatering 2012-12-20: Oppdaget at -bloggposten -til Geir Aaslid er endret siden i går, og nå inneholder følgende -avsnitt i stedet for det jeg siterte over:

    +

    Det bør nevnes at da jeg ble nektet innsyn hos mottaker +Fornyingsdepartementet på høringsoppsummeringen som DIFI hadde sendt +ut, spurte jeg DIFI om innsyn i stedet. Det fikk jeg i løpet av et +par dager. Moralen er at hvis ikke mottaker ikke vil gi innsyn, spør +avsender i stedet. Kanskje de har forskjellig forståelse av hva som +bør holdes skjult for folket. Her er de tilsvarende dokumentene jeg +fikk innsyn i fra DIFI:

    -
    -Hva vi gjør med opphavsretten er mer komplisert fordi den omfavner så -mange bransjer, med ulike behov. Enhver reform er en forbedring men -det er nærliggende å anta at en opphavsrett lik levetiden, evt + 14 år -er fullt ut tilfredstillende for mange skapere av musikk, film, -litteratur og spill. Det er for det meste de store forlagene som er -imot enhver reform. -
    + + +

    Det jeg synes er mest interessant er endel av aktørene som +protesterte på fjerningen (Kartverket, Drammen kommune), og hvordan +høringsoppsummeringen ikke tar stilling til effekten av å fjerne ODF +fra katalogen.

    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.

    + +

    Jeg har stor sans for Tor Åge Bringsværd. Og han viste nylig en +svært fin side av seg selv da han sa ja til EFNs forespørsel om å gi +ut novellen Kodémus med +Creative Commons-lisens.
