+ Officeshots taking shape +

+ +

For those of us caring about document exchange and +interoperability, OfficeShots +is a great service. It is to ODF documents what +BrowserShots is for web +pages.

+ +

A while back, I was contacted by Knut Yrvin at the part of Nokia +that used to be Trolltech, who wanted to help the OfficeShots project +and wondered if the University of Oslo where I work would be +interested in supporting the project. I helped him to navigate his +request to the right people at work, and his request was answered with +a spot in the machine room with power and network connected, and Knut +arranged funding for a machine to fill the spot. The machine is +administrated by the OfficeShots people, so I do not have daily +contact with its progress, and thus from time to time check back to +see how the project is doing.

+ +

Today I had a look, and was happy to see that the Dell box in our +machine room now is the host for several virtual machines running as +OfficeShots factories, and the project is able to render ODF documents +in 17 different document processing implementation on Linux and +Windows. This is great.

+ Vinmonopolet bryter loven åpenlyst - og flere planlegger å gjøre det samme +
+
+ 2010-06-16 11:00 +
+ +
+ +

Dagbladet +melder at Vinmonopolet med bakgrunn i vekterstreiken som pågår i +Norge for tiden, har bestemt seg for med vitende og vilje å bryte +sentralbanklovens paragraf 14 ved å nekte folk å betale med +kontanter, og at flere butikker planlegger å følge deres eksempel. +Jeg synes det er hårreisende hvis de slipper unna med et slikt +soleklart lovbrudd, og lurer på hva slags muligheter jeg vil ha hvis +jeg blir nektet å handle med kontanter. Jeg handler i hovedsak med +kontanter selv, da jeg anser det som en borgerrett å kunne handle +anonymt uten at det blir registrert. For meg er det et angrep på mitt +personvern å nekte å ta imot kontant betaling.

+ +

Paragrafen +i sentralbankloven lyder:

+ +
+

§ 14. Tvungent betalingsmiddel

+ +

Bankens sedler og mynter er tvungent betalingsmiddel i Norge. Ingen +er pliktig til i én betaling å ta imot mer enn femogtyve mynter av +hver enhet.

+ +

Sterkt skadde sedler og mynter er ikke tvungent +betalingsmiddel. Banken gir nærmere forskrifter om erstatning for +bortkomne, brente eller skadde sedler og mynter.

+ +

Selv om en avtale inneholder klausul om betaling av en +pengeforpliktelse i gullverdi, kan skyldneren frigjøre seg med tvungne +betalingsmidler uten hensyn til denne klausul.

+
+ +

Det er med bakgrunn i denne lovet ikke tillatt å nekte å ta imot +kontakt betaling. Det er en lov jeg har sans for, og som jeg mener må +håndheves strengt.

+ Calling tasksel like the installer, while still getting useful output +
+
+ 2010-06-16 14:55 +
+ +
+ +

A few times I have had the need to simulate the way tasksel +installs packages during the normal debian-installer run. Until now, +I have ended up letting tasksel do the work, with the annoying problem +of not getting any feedback at all when something fails (like a +conffile question from dpkg or a download that fails), using code like +this: + +

+export DEBIAN_FRONTEND=noninteractive
+tasksel --new-install
+
+ +This would invoke tasksel, let its automatic task selection pick the +tasks to install, and continue to install the requested tasks without +any output what so ever. + +Recently I revisited this problem while working on the automatic +package upgrade testing, because tasksel would some times hang without +any useful feedback, and I want to see what is going on when it +happen. Then it occured to me, I can parse the output from tasksel +when asked to run in test mode, and use that aptitude command line +printed by tasksel then to simulate the tasksel run. I ended up using +code like this: + +
+export DEBIAN_FRONTEND=noninteractive
+cmd="$(in_target tasksel -t --new-install | sed 's/debconf-apt-progress -- //')"
+$cmd
+
+ +

The content of $cmd is typically something like "aptitude -q +--without-recommends -o APT::Install-Recommends=no -y install +~t^desktop$ ~t^gnome-desktop$ ~t^laptop$ ~pstandard ~prequired +~pimportant", which will install the gnome desktop task, the +laptop task and all packages with priority standard , required and +important, just like tasksel would have done it during +installation.

+ +

A better approach is probably to extend tasksel to be able to +install packages without using debconf-apt-progress, for use cases +like this.

+ Idea for a change to LDAP schemas allowing DNS and DHCP info to be combined into one object +
+
+ 2010-06-24 00:35 +
+ +
+ +

A while back, I +complained +about the fact that it is not possible with the provided schemas +for storing DNS and DHCP information in LDAP to combine the two sets +of information into one LDAP object representing a computer.

+ +

In the mean time, I discovered that a simple fix would be to make +the dhcpHost object class auxiliary, to allow it to be combined with +the dNSDomain object class, and thus forming one object for one +computer when storing both DHCP and DNS information in LDAP.

+ +

If I understand this correctly, it is not safe to do this change +without also changing the assigned number for the object class, and I +do not know enough about LDAP schema design to do that properly for +Debian Edu.

+ +

Anyway, for future reference, this is how I believe we could change +the +DHCP +schema to solve at least part of the problem with the LDAP schemas +available today from IETF.

+ +
+--- dhcp.schema    (revision 65192)
++++ dhcp.schema    (working copy)
+@@ -376,7 +376,7 @@
+ objectclass ( 2.16.840.1.113719.1.203.6.6

+
+ +

I very much welcome clues on how to do this properly for Debian +Edu/Squeeze. We provide the DHCP schema in our debian-edu-config +package, and should thus be free to rewrite it as we see fit.

+ +

If you want to help out with implementing this for Debian Edu, +please contact us on debian-edu@lists.debian.org.

+ LUMA, a very nice LDAP GUI +
+
+ 2010-06-28 00:30 +
+ +
+ +

The last few days I have been looking into the status of the LDAP +directory in Debian Edu, and in the process I started to miss a GUI +tool to browse the LDAP tree. The only one I was able to find in +Debian/Squeeze and Lenny is +LUMA, which has proved to +be a great tool to get a overview of the current LDAP directory +populated by default in Skolelinux. Thanks to it, I have been able to +find empty and obsolete subtrees, misplaced objects and duplicate +objects. It will be installed by default in Debian/Squeeze. If you +are working with LDAP, give it a go. :)

+ +

I did notice one problem with it I have not had time to report to +the BTS yet. There is no .desktop file in the package, so the tool do +not show up in the Gnome and KDE menus, but only deep down in in the +Debian submenu in KDE. I hope that can be fixed before Squeeze is +released.

+ +

I have not yet been able to get it to modify the tree yet. I would +like to move objects and remove subtrees directly in the GUI, but have +not found a way to do that with LUMA yet. So in the mean time, I use +ldapvi for that.

+ +

If you have tips on other GUI tools for LDAP that might be useful +in Debian Edu, please contact us on debian-edu@lists.debian.org.

+ +

Update 2010-06-29: Ross Reedstrom tipped us about the +gq package as a +useful GUI alternative. It seem like a good tool, but is unmaintained +in Debian and got a RC bug keeping it out of Squeeze. Unless that +changes, it will not be an option for Debian Edu based on Squeeze.
