This guide seems to explain it all.
You may run into errors of the form:
$ reprepro -Vb . includedeb jaunty /path/to/package.deb
Error: Distribution jaunty contains an architecture called 'all'.
There have been errors!
$ reprepro -Vb . dumpreferences
Error: Distribution jaunty contains an architecture called 'all'.
There have been errors!
$
In that case, try removing all from the “architectures” line of nano conf/distributions.

Ordinary file-permissions are apparently not sufficient anymore. Ubuntu, and others, therefore uses AppArmor to associate programs with certain permission filters.
One such program is MySQL. When changing the datadir, it will most likely land somewhere outside the permissions granted by AppArmor and as a result fail. I would get errors (from /var/log/syslog) of the form:
Jan 19 00:41:12 asjo kernel: [262573.788599] type=1503 audit(1232322072.553:28): operation="inode_permission" requested_mask="r::" denied_mask="r::" fsuid=116 name="/vol/mysql/" pid=18262 profile="/usr/sbin/mysqld"
Others were having similar problems, as described in this thread among others.
This page solved my problem. Basically, you first put AppArmor in complain-mode regarding the specific program (in this case /usr/sbin/mysqld) by running this command:
sudo aa-complain /usr/sbin/mysqld
This will temporarily turn off the security and log the offending actions. Generate the offending actions by running the program:
sudo /etc/init.d/mysql start
Next you run
sudo aa-logprof
When asked if I wanted to “enable access to the profile repository” I answered L for ‘later’. Next it displays the offending action previously logged, at which point a allow it by answering A. At this point I am asked if I would like to save the changes. S for yes (save).
In order to re-enable security you simply run:
sudo aa-enforce /usr/sbin/mysqld
Today is the shortest day of the year. The event is called the winter solstice and signals the return of the sun. This – of course – will take some time before reaching full effect, but till then one can take rest in knowing that the days are getting longer.
This post is in danish. Sorry …
For et par år siden skrev jeg en introduktion til Python rettet mod folk med kendskab til imperative sprog. Vi var et par stykker der skulle lære sproget og jeg satte mig for at lave en række repræsentative opgaver. Introduktionen er derfor opbygget som et (fiktivt) kursus. Følgende områder berøres:
De afsluttende opgaver bærer præg af, at jeg skulle finde på nogle ekstra opgaver uden – på forhånd – at kende deres svar.

UFRaw is a free converter for RAW images. Like so many others it is based on DCRaw. The latest official release is from late 2007. This is more or less what is provided by Ubuntu.
The current CVS holds a few interesting additions, most noticeable the use of lensfun for doing lens corrections. There is a demo.
The following steps made the CVS compile for me. The result will be placed within the confines of /opt/ufraw-cvs/ and dpkg.
First we need to get the lensfun packages. I found some at this location. Add the following lines to /etc/apt/sources.list (use su to become a privileged user):
# lensfun
deb http://mirror.pcode.nl/ubuntu/ hardy lensfun
Next, install needed deb packages:
sudo apt-get update
sudo apt-get install build-essential
sudo apt-get install lensfun-data lensfun-manual liblensfun0 liblensfun0-dev
sudo apt-get install libgtkimageview-dev libgtkimageview0
In case you don’t have a /opt directory:
sudo mkdir /opt
Then build the programs:
cd /tmp
cvs -d:pserver:anonymous@ufraw.cvs.sourceforge.net:/cvsroot/ufraw login
cvs -z3 -d:pserver:anonymous@ufraw.cvs.sourceforge.net:/cvsroot/ufraw co ufraw
cd ufraw
./autogen.sh
./configure --prefix=/opt/ufraw-cvs
make
sudo make install
And you should then be able to run UFRaw:
/opt/ufraw-cvs/bin/ufraw
In an earlier post I mentioned a guide to build Gimp 2.5.0 on Ubuntu Hardy Heron. Back then the guide failed on my machine.
With the recent release on Gimp 2.5.2 I decided to give it another try and this time it worked. Below I have listed the specific commands. A few dependencies might be missing.
I case you don’t have the build tools installed (or have no idea if you do):
sudo apt-get install build-essential
sudo apt-get build-dep gimp
Also, to make the commands below work you need to have wget installed:
sudo apt-get install wget
In case you don’t have a /opt directory:
sudo mkdir /opt
In case you have a previous installation, remove this (or move it out of the way):
sudo mv /opt/gimp-2.5 /opt/gimp-2.5.backup
Run the following commands:
export PATH=/opt/gimp-2.5/bin:$PATH
export LD_LIBRARY_PATH=/opt/gimp-2.5/lib
export PKG_CONFIG_PATH=/opt/gimp-2.5/lib/pkgconfig
cd /tmp
svn co http://svn.gnome.org/svn/babl/trunk/ babl
cd babl
./autogen.sh –prefix=/opt/gimp-2.5
make
sudo make install
cd ..
svn co http://svn.gnome.org/svn/gegl/trunk/ gegl
cd gegl
./autogen.sh –prefix=/opt/gimp-2.5
make
sudo make install
cd ..
wget ftp://ftp.gimp.org/pub/gimp/v2.5/gimp-2.5.2.tar.bz2
tar jxvf gimp-2.5.2.tar.bz2
cd gimp-2.5.2
./configure –prefix=/opt/gimp-2.5
make
sudo make install
If everything went well you should be able to start it by running:
/opt/gimp-2.5/bin/gimp-2.5
Conversion of file encoding can be done easily and in a scriptable fashion using iconv (man page):
iconv -f latin1 -t utf-8 rapport.tex.old >> rapport.tex
The example above converts the file rapport.tex.old from latin1 (ISO-8859-1) to UTF-8. The result is stored in rapport.tex leaving the old file untouched.

Danske Bank’s netbank benytter Java. Under Ubuntu Hardy Heron betyder det, at man har valget mellem sun-java5-plugin, sun-java6-plugin og de mere eksotiske udgaver. sun-java6-plugin lader kun delvist til at virke og virker ikke de vigtige steder. Eftersom de tidligere har haft problemer med Java er det nok fair at gå ud fra, at de eksotiske implementationer heller ikke virker. Efter at have installeret sun-java5-plugin lader tingene til at virke.
The Oil drum has some, rather technical, insights on the current and future price of the oil barrel. Nothing new really, but graphs are presented.
The Gimp has recently begun the process of migrating to the GEGL backend in the 2.5 series. This version has not been packaged by the Ubuntu team.
There is a guide for building GIMP 2.5 on Hardy Heron, but it fails on my system. Somebody did manage to get it working and created a DEB package of the result. This does work for me. Details here.
This installs in parallel with the existing gimp package, so no harm in giving it a try …
Recent versions of Ubuntu Linux have been missing the devhelp-book-glibc package which provides DevHelp with support for the GNU C Library.
Installing the Debian Sarge package works for the upcomming Hardy Heron release. It does unfortunately have some minor markup glitches.
Ubuntu provides some ‘official’ VmWare images here. These can be played using the VmWare Player. Password is ‘ubuntu’ without the quotes.
Images for Hardy Heron are not up yet, but then again it hasn’t been (officially) released yet.
Today it’s the winter solstice. On the northern hemisphere this is the shortest day, so now the days will start getting longer and brighter. This is truly cause for celebration.
Facebook have finally offered a solution to one of their major privacy issues: Beacon. Users of the webside can now completely opt-out. Mark Zuckerberg, CEO of Facebook, apologizes and provides a link for doing so.
Now we only need Facebook to change their terms of use, so that they are no longer allowed to do whatever to whatever information they gather about the users. See this facebook group for details.
It seems like these issues will continue, especially since the alliance with Microsoft.
