In the moment I work on a WebMapping Project, wich uses the ArcGIS JavaScript API for Virtual Earth,
to bring ArcGIS Server mapservices into Virtual Earth Applications.
All in all the API is not that bad, and Virtual Earth is quite nice I think, but the API is really bad documented.

And that with a multi thousand € software!!!

For christmas I got a little book called math for the vest pocket (in german: Mathematik für die Westentasche) by the math Professor Albrecht Beutelspacher.
It is a popular science book and consists of 52 short topics on general math from "golden section" over "Fermat's last Theorem" to "Traveling Salesman Problem". Today I read the topic about "a cord around the equator".

I was very curious on the Linux Silverlight port called Moonlight, because VirtualEarth3D runs with Silverlight.
When you access a Silverlight enabled page via Firefox on a Linux machine you get forwarded here to download a firefox plugin.

I just read a very interesting article on telepolis.de:

-> http://www.heise.de/tp/r4/artikel/29/29276/1.html

It is an Interview with the future scientist Matthias Horx.
In the context of crisis entertainment - entertainment out of natural catastrophes, like seen on the mass media - the Interviewer asks, to what degree the climate change discussion is a type of "crisis entertainment".

1. Make shure you have a java-jdk installed.

2. Download the actual tar.gz file from the tomcat homepage. (I used 'apache-tomcat-6.0.18.tar.gz')

3. unpack the tar.gz file and move it to /usr/local/tomcat


tar xvzf apache-tomcat-6.0.18.tar.gz
mv apache-tomcat-6.0.18 /usr/local/tomcat

4. create an init script for tomcat

nano /etc/init.d/tomcat

5. Paste the following code in that script.
(take care of the java path depending on your java installation
sun version: /usr/lib/jvm/java-6-sun
gcj version: /usr/lib/jvm/java-gcj)

The apt sources of the default Ubuntu 8.04 installation of the Strato V-power servers are not set to multiverse. So when you want to install the sun-java packages, you have to add multiverse.

For this just do the following:

vi /etc/apt/sources.list

and add the string "multiverse" at the end of every 'deb' line.
The result should look like this:

# See sources.list(5) for more information, especialy
# Remember that you can only use http, ftp or file URIs
# CDROMs are managed through the apt-cdrom tool.
