+ OpenStreetmap one step closer to having routing on its front page +
+
+ 2010-07-18 16:45 +
+ +
+ +

Thanks to +todays +opengeodata blog entry, I just discovered that the +OpenStreetmap.org site have gotten +support +for calculating routes. The support is still experimental and +only available from the development server, until more experience is +gathered on the user interface and any scalability issues.

+ +

Earlier, the routing I knew about using the OpenStreetmap.org data +was provided by Cloudmade, +but having it on the main page is required to make everyone aware of +the issue. I've had people reject Openstreetmap.org as a viable +alternative for them because the front page lacked routing support, +and I hope their needs will be catered for when routing show up on the +www.openstreetmap.org front page.

+ Digitale restriksjonsmekanismer fikk meg til å slutte å kjøpe musikk +
+
+ 2010-07-22 23:50 +
+ +
+ +

For mange år siden slutte jeg å kjøpe musikk-CDer. Årsaken var at +musikkbransjen var godt i gang med å selge platene sine med DRM som +gjorde at jeg ikke fikk spilt av musikken jeg kjøpte på utstyret jeg +hadde tilgjengelig, dvs. min datamaskin. Det var umulig å se på en +plate om den var ødelagt eller ikke, og jeg hadde jo allerede en +anseelig samling med plater, så jeg bestemme meg for å slutte å gi +penger til en bransje som åpenbart ikke respekterte meg.

+ +

Jeg har mange titalls dager med musikk på CD i dag. Det meste er +lagt i et stort arkiv som kan spilles av fra husets datamaskiner (har +ikke rukket rippe alt). Jeg ser dermed ikke behovet for å skaffe mer +musikk. De fleste av mine favoritter er i hus, og jeg er dermed godt +fornøyd.

+ +

Hvis musikkbransjen ønsker mine penger, så må de demonstrere at de +setter pris på meg som kunde, og ikke skremme meg bort med DRM og +antydninger om at kundene er kriminelle.

+ +

Filmbransjen er like ille, men mens musikk gjerne varer lenge, er +filmer mer ferskvare. Har dermed ikke helt sluttet å kjøpe filmer, men +holder meg til DVD-filmer som kan spilles av på mine Linuxbokser. +Kommer neppe til å ta i bruk Blueray, og ei heller de nye DRM-greiene +«Ultraviolet» som be annonsert her om dagen.

+ One step closer to single signon in Debian Edu +
+
+ 2010-07-25 10:00 +
+ +
+ +

The last few months me and the other Debian Edu developers have +been working hard to get the Debian/Squeeze based version of Debian +Edu/Skolelinux into shape. This future version will use Kerberos for +authentication, and services are slowly migrated to single signon, +getting rid of password questions one at the time.

+ +

It will also feature a roaming workstation profile with local home +directory, for laptops that are only some times on the Skolelinux +network, and for this profile a shortcut is created in Gnome and KDE +to gain access to the users home directory on the file server. This +shortcut uses SMB at the moment, and yesterday I had time to test if +SMB mounting had started working in KDE after we added the cifs-utils +package. I was pleasantly surprised how well it worked.

+ +

Thanks to the recent changes to our samba configuration to get it +to use Kerberos for authentication, there were no question about user +password when mounting the SMB volume. A simple click on the shortcut +in the KDE menu, and a window with the home directory popped +up. :)

+ +

One step closer to a single signon solution out of the box in +Debian Edu. We already had PAM, LDAP, IMAP and SMTP in place, and now +also Samba. Next step is Cups and hopefully also NFS.

+ +

We had planned a alpha0 release of Debian Edu for today, but thanks +to the autobuilder administrators for some architectures being slow to +sign packages, we are still missing the fixed LTSP package we need for +the release. It was uploaded three days ago with urgency=high, and if +it had entered testing yesterday we would have been able to test it in +time for a alpha0 release today. As the binaries for ia64 and powerpc +still not uploaded to the Debian archive, we need to delay the alpha +release another day.

+ +

+ First Debian Edu test release (alpha0) based on Squeeze is released +
+
+ 2010-07-27 17:45 +
+ +
+ +

I just posted this announcement culminating several months of work +with the next Debian Edu release. Not nearly done, but one major step +completed.

+ +
+

This is the first test release based on Squeeze. The focus of this +release is to test the user application selection. To have a look, +install the standalone profile and let the developers know if the set +of installed packages i.e. applications should be modified. If some +user application is missing, or if there are some applications that no +longer make sense to be included in Debian Edu, please let us know. +Also, if a useful application is missing the translation for your +language of choice, please let us know too.

+ +

In addition, feedback and help to polish the desktop (menus, +artwork, starters, etc.) is appreciated. We would like to ship a nice +and handy KDE4 desktop targeted for schools out of the box.

+ +

The other profiles should be installable, but there is a lot more +work left to be done before they are ready, so do not expect to +much.

+ +

Changes compared to the lenny based version

+ +
    +
  • Everything from Debian Squeeze +
      +
    • Desktop environment KDE 4.4 => the new KDE desktop in + combination with some new artwork +

    • Virtual stargazer Stellarium 0.10.4 +
    • 3D modeler Blender 2.49.2 (new application) +
    • Video editor Kdenlive 0.7.7 (new application) +
    • +

    • IMAP +
    • SMTP (sender verification) +
    +
    • +
  • New experimental roaming workstation profile for laptops.
    • +
  • Show welcome page to users when they first log in. The URL is + fetched from LDAP.
    • +
  • New LXDE desktop option, in addition to KDE (default) and Gnome.
    • +
  • General cleanup (not finished)
    • +
+

The following features are not working as they should

+ +
    +
  • No web based administration tool for creating users and groups. The + scripts ldap-createuser-krb and ldap-add-user-to-group can be used + for testing.
    • +
  • DVD installs are missing debian-installer images for the PXE boot, + and do not set up the PXE menu on eth0 because of this. LTSP + clients should still boot from eth1 on thin client servers.
    • +
  • The restructured KDE menu is not implemented.
    • +
  • The LDAP server setup need to be reviewed for security.
    • +
  • The LDAP directory structure need to be reworked.
    • +
  • Different sets of packages are installed when using the DVD and the + netinst CD. More packages are installed using the netinst CD.
    • +
  • The jackd package fail to install. This is believed to be caused by + some ongoing transition, and hopefully should be solved soon. The + jackd1 package can be installed manually for those that need it.
    • +
  • Some packages lack translations. See + http://wiki.debian.org/DebianEdu/Status/Squeeze for updated status, + and help out with translations.
    • +
+ +

+ Circular package dependencies harms apt recovery +
+
+ 2010-07-27 23:50 +
+ +
+ +

I discovered this while doing +automated +testing of upgrades from Debian Lenny to Squeeze. A few packages +in Debian still got circular dependencies, and it is often claimed +that apt and aptitude should be able to handle this just fine, but +some times these dependency loops causes apt to fail.

+ +

An example is from todays +upgrade +of KDE using aptitude. In it, a bug in kdebase-workspace-data +causes perl-modules to fail to upgrade. The cause is simple. If a +package fail to unpack, then only part of packages with the circular +dependency might end up being unpacked when unpacking aborts, and the +ones already unpacked will fail to configure in the recovery phase +because its dependencies are unavailable.

+ +

In this log, the problem manifest itself with this error:

+ +
+dpkg: dependency problems prevent configuration of perl-modules:
+ perl-modules depends on perl (>= 5.10.1-1); however:
+  Version of perl on system is 5.10.0-19lenny2.
+dpkg: error processing perl-modules (--configure):
+ dependency problems - leaving unconfigured
+
+ +

The perl/perl-modules circular dependency is already +reported as a bug, and will +hopefully be solved as soon as possible, but it is not the only one, +and each one of these loops in the dependency tree can cause similar +failures. Of course, they only occur when there are bugs in other +packages causing the unpacking to fail, but it is rather nasty when +the failure of one package causes the problem to become worse because +of dependency loops.

+ +

Thanks to +the +tireless effort by Bill Allombert, the number of circular +dependencies +left in Debian +is dropping, and perhaps it will reach zero one day. :)

+ +

Todays testing also exposed a bug in +update-notifier and +different behaviour between +apt-get and aptitude, the latter possibly caused by some circular +dependency. Reported both to BTS to try to get someone to look at +it.
