How to find a browser plugin supporting a given MIME type
-
18th January 2013
-

Some times I try to figure out which Iceweasel browser plugin to -install to get support for a given MIME type. Thanks to -specifications -done by Ubuntu and Mozilla, it is possible to do this in Debian. -Unfortunately, not very many packages provide the needed meta -information, Anyway, here is a small script to look up all browser -plugin packages announcing ther MIME support using this specification:

- -
-#!/usr/bin/python
-import sys
-import apt
-def pkgs_handling_mimetype(mimetype):
-    cache = apt.Cache()
-    cache.open(None)
-    thepkgs = []
-    for pkg in cache:
-        version = pkg.candidate
-        if version is None:
-            version = pkg.installed
-        if version is None:
-            continue
-        record = version.record
-        if not record.has_key('Npp-MimeType'):
-            continue
-        mime_types = record['Npp-MimeType'].split(',')
-        for t in mime_types:
-            t = t.rstrip().strip()
-            if t == mimetype:
-                thepkgs.append(pkg.name)
-    return thepkgs
-mimetype = "audio/ogg"
-if 1 < len(sys.argv):
-    mimetype = sys.argv[1]
-print "Browser plugin packages supporting %s:" % mimetype
-for pkg in pkgs_handling_mimetype(mimetype):
-    print "  %s" %pkg
-
- -

It can be used like this to look up a given MIME type:

- -
-% ./apt-find-browserplug-for-mimetype 
-Browser plugin packages supporting audio/ogg:
-  gecko-mediaplayer
-% ./apt-find-browserplug-for-mimetype application/x-shockwave-flash
-Browser plugin packages supporting application/x-shockwave-flash:
-  browser-plugin-gnash
-%
-
- -

In Ubuntu this mechanism is combined with support in the browser -itself to query for plugins and propose to install the needed -packages. It would be great if Debian supported such feature too. Is -anyone working on adding it?

- -

Update 2013-01-18 14:20: The Debian BTS -request for icweasel support for this feature is -#484010 from 2008 (and -#698426 from today). Lack -of manpower and wish for a different design is the reason thus feature -is not yet in iceweasel from Debian.

The Debian Edu / Skolelinux +project is making great progress and made its second Wheezy based +release today. This is the release announcement:

+ +

New features for Debian Edu 7.0.0 alpha1 released +2013-05-14

+ +

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.
  • +
+ +

Other changes

+
    + +
  • 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.
  • +
  • Fix bug in Roaming workstation PAM setup, making it impossible to + log in (706753).
  • +
+ +

Known issues

+
    + +
  • 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).
  • + +
+ +

Where to get it

+ +

To download the multiarch netinstall CD release you can use

The DEP-11 -proposal to add AppStream information to the Debian archive, is a -proposal to make it possible for a Desktop application to propose to -the user some package to install to gain support for a given MIME -type, font, library etc. that is currently missing. With such -mechanism in place, it would be possible for the desktop to -automatically propose and install leocad if some LDraw file is -downloaded by the browser.

- -

To get some idea about the current content of the archive, I decided -to write a simple program to extract all .desktop files from the -Debian archive and look up the claimed MIME support there. The result -can be found on the -Skolelinux FTP -site. Using the collected information, it become possible to -answer the question in the title. Here are the 20 most supported MIME -types in Debian stable (Squeeze), testing (Wheezy) and unstable (Sid). -The complete list is available from the link above.

In January, +I +announced a new IRC +channel #debian-lego, for those of us in the Debian and Linux +community interested in LEGO, the +marvellous construction system from Denmark. We also created +a wiki page to have +a place to take notes and write down our plans and hopes. And several +people showed up to help. I was very happy to see the effect of my +call. Since the small start, we have a debtags tag +hardware::hobby:lego +tag for LEGO related packages, and now count 10 packages related to +LEGO and Mindstorms:

+ +

+ + + + + + + + + + +
brickosalternative OS for LEGO Mindstorms RCX. Supports development in C/C++
leocadvirtual brick CAD software
libnxtutility library for talking to the LEGO Mindstorms NX
lnpddaemon for LNP communication with BrickOS
nbccompiler for LEGO Mindstorms NXT bricks
nqcNot Quite C compiler for LEGO Mindstorms RCX
python-nxtpython driver/interface/wrapper for the Lego Mindstorms NXT robot
python-nxt-filersimple GUI to manage files on a LEGO Mindstorms NXT
scratcheasy to use programming environment for ages 8 and up
t2nsimple command-line tool for Lego NXT

+ +

Some of these are available in Wheezy, and all but one are +currently available in Jessie/testing. leocad is so far only +available in experimental.

If you care about LEGO in Debian, please join us on IRC and help +adding the rest of the great free software tools available on Linux +for LEGO designers.

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.

I fjor sommer ble jeg +gledelig +overrasket over et oppslag i avisen Fremover om Narvik kommunes +bruk av Skolelinux. Oppslaget +var basert på et notat som besvarte spørsmål fra ordfører Tor Nysæter +og rådgiver for skolesektoren, Petter Falkbu, om bruken av Skolelinux +i Narvikskolene og konstnaden ved å gå over til Windows. For litt +over en uke siden siden fikk jeg endelig bedt kommunen om å få innsyn +i dette notatet, og det ble oversendt på epost tirsdag. Jeg fikk +lagt +ut notatet samme dag, og fikk i dag sjekket postlista til Narvik, +der jeg fant notatet som +sak +2013/1023.

+ +

Notatet forteller at Narvik ville måtte betalt minst 9 millioner +for å gå over til Windows på skolene. I tillegg dokumenterer notatet +at læreplanens krav oppfylles uten problemer ved bruk av Skolelinux. +Jeg anbefaler alle å lese de 10 sidene med gode argumenter for å kutte +unødige utgifter på IT i skoleverket. :)

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:

-find /sys -name modalias -print0 | xargs -0 cat | sort -u

When I woke up this morning, I was very happy to see that the +release announcement +for Debian Wheezy was waiting in my mail box. This is a great +Debian release, and I expect to move my machines at home over to it fairly +soon.

+ +

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. Alongside similar programs like +kturtle and +turtleart, +it allow for visual programming where syntax errors can not happen, +and a friendly programming environment for learning to control the +computer. Scratch will also be included in the next release of Debian +Edu. + +

And now that Wheezy is wrapped up, we can wrap up the next Debian +Edu/Skolelinux release too. The +first +alpha release went out last week, and the next should soon +follow.

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.

+ +

- bc  06        (bus class)
- sc  00        (bus subclass)
- i   00        (interface)
-
+

Tjenestekonseptet kan også brukes til andre næringer, f.eks. lege, +butikk, leiebiler, hvis en har aktuell datakilde å koble med.

-

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).

+

Skulle gjerne hatt med vurdering av tannlegene tilgjengelig, slik +at en kunne finne "flinke" tannleger basert på et eller annet +kriterium.

-

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

+

Markedspotensiale - potensiale for å slå gjennom hos mange +brukere

X-faktor - “Det lille ekstra...”

-

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:

+

Denne tjenesten gir det lille ekstra ved at den ikke slår opp +avstand til tannlege fra et enkelt punkt men avstand fra en reisevei, +slik at en får flere tannleger å velge imellom og kanskje kan spare +enda mer tid og penger enn en ville gjort ved å sjekke kun de nærmest +hjemme eller jobb.

usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc02ip00 -

+

Tjenesten gir informasjonen både som kart og som tekstlig oversikt, for å sikre at blinde og svaksynte kan få tilgang til informasjonen selv om de ikke får brukt kartvisningen.

-

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.

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

- -
-  for id in $(find /sys -name modalias -print0 | xargs -0 cat | sort -u); do \
-    echo "$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):

- -

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. If you want to check out -the new version with a .desktop file included, visit the -gitweb -view or use "git clone -git://anonscm.debian.org/collab-maint/pymissile.git".

The Debian Edu / Skolelinux project is still going strong and made +its first Wheezy based release today. This is the release +announcement:

+ +

New features for Debian Edu ~7.0.0 alpha0 released +2013-04-26

+ +

This is the release notes for for Debian Edu / Skolelinux ~7.0.0 +edu alpha0, 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.

+ +

    • +
    • More information about Debian Wheezy 7.0 is provided in the + release notes and the installation manual.
    • +
  • +
+ +

Documentation

+
    +
  • The (English) Debian Edu Wheezy Manual is fully translated to + German, French, Italian and Danish. Partly translated versions exist + for Norwegian Bokmal and Spanish.
  • +
+ +

LDAP related changes

+
    +
  • Slight changes to some objects and acls to have more types to + choose from when adding systems in GOsa. Now systems can be of type + server, workstation, printer, terminal or netdevice.
  • +
+ +

Other changes

+
    +
  • LTSP clients start as diskless workstation / thin client can be + configured via command line argument -- or individually adding an + entry in lts.conf or LDAP.

  • +
+ +

Regressions

+
    +
  • No mass import of user account data in GOsa (ldif or csv) available + yet.
  • +
+ +

No updated artwork

+ +

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.

    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:

    -
  • When new hardware is inserted, look up the hardware ID in a - database mapping to packages, and take note of any non-installed - packages.
  • +

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

    -
  • Show a message to the user proposing to install the discovered - package, and make it easy to install it.
  • +

    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.» +

-

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. :)

+

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.

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.

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.

    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.
