Alles über meine Arbeit

In Acrobat 6 you first have to enable the Tools keyboard shortcuts (see picture).

then you can press Ctrl+l to go to fullscreen mode, then press n to enable the pen tool.

With xetex you can easily use Opentype fonts in latex. There is no need for any conversion or anything, xetex can use any of the fonts you installed on your system (works fine unter linux) even if its opentype fonts that are not postscript, but truetype flavored. Unter Gentoo Linux you just install app-text/xetex (additionally to tetex) and thats it!

% Load fontspec package to easily use fonts
\usepackage{fontspec}
% set fonts
\fontspec[BoldFont={Textra LT Com}, BoldFeatures={Weight=1.4}]{Textra LT Com}
\setromanfont{Textra LT Com}
%\setsansfont{Textra LT Com}
%\setmonofont{Textra LT Com}

Inserting this makes the default font "Textra LT Com" (you can find out this name with fc-list). Then you can run xelatex (i.e. "xelatex myfile" if your tex file is called myfile.tex) on the File and it will result in a pdf nicely formatted using your font. [Update 2007-06-21]: If you upgraded freetype to Version >2.1.10-r3 (media-libs/freetype-2.1.10-r3) this might break the opentype/xetex support. So just downgrade to 2.1.10-r3 and everything should be fine again.

emerge -av =media-libs/freetype-2.1.10-r3

[Update 2007-07-23]: Make sure you also mask freetype packages > this Version, else the next upgrade will break it again

grep freetype /etc/portage/package.mask
>media-libs/freetype-2.1.10-r3

First, one has to download the Lecturnity Jar File. Then, i wrote this small shell-script (i called it "lecturnity-player") to start the lecturnity player with parameters:

#!/bin/sh

JAR="player170p6.jar"

# check Java Home and set it if not available (Gentoo-Version)
if [ -z "$JAVA_HOME" -o "$JAVA_HOME" = "" ]
then
        JAVA_HOME=`java-config --jre-home`
fi

$JAVA_HOME/bin/java -jar /opt/lecturnity/$JAR $@

If $JAVA_HOME is already set on your system (echo $JAVA_HOME) you don't need the JAVA_HOME-Check. chmod the File executable: chmod u+x lecturnity-player Then you can play lecturnity Files with lecturnity-player /path/to/file.lpd. One Remark: It is not possible to player the Video Versions under Linux (at least it does not work here, it simply plays them without Video). Using this with Firefox: Click on a link to a Lecturnity File and choose lecturnity-player in the "run with" Dialog. Then Lecturnity Files will automatically play when you click on a link (takes some time to start the player).

Today we had a visit by a bird of prey (Greifvogel; Turmfalke (in german) also known as Falco tinnunculus). He seemed to be very young and shy. Thats why i first took a picture through the windows (good idea) because when i tried to open the window very silently he flew away . Anyway at least i got one picture

K: I threw the butter out of the window. Do you know why?
C: hm?
K: Because i wanted to see the butter fly.

K: You always sleep longer than all of us. Do you know why?
C: No?
K: You are taller than all of us.

Mir scheint die Firmware unseres Kopierers wurde geupgraded. Anstatt

Schlüsselzähler einstecken

berichtet er jetzt

Benutzercode eingeben.

Ich hoffe jedenfalls, dass sich damit auch das "Tonerrest entfernen"-Problem gelöst hat, das eigentlich "Papierstau entfernen"-Problem heissen müsste.

[Update 2007-02-07 15:26]

Wie ich gerade erfahren habe kriegen wir morgen einen ganz neuen Kopierer, weil unserer schon wieder streikt.

On 29th of January Tobias held his Disputation about his Thesis "Potentials and Limitations of Visual Methods for the Exploration of
Complex Data Structures". The talk was very interesting and although Tobias was very nervous at the beginning he made it (in my opinion) very good.
I took some pictures of the "Event" which you can see at the AD Gallery.

This is how the authors List on Papers is ordered. You can verify this easily through Google Scholar.
Thanks to phdcomic.com.

I just discovered a nice little Comic on phdcomics.com which gives you hints on what name your thesis shall have.

Guten Tag,
wir wollen ein "Ping Pong Spiel" mit Javascript herstellen. Aber wir haben ein Problem und kommen nicht weiter. Dann kamen wir auf die Idee an die Universität für Informatik in Rostock zu schreiben und um Hilfe zu bitten.

Okay, University of Rostock... very interesting.

Today i uploaded the pictures from our trip to the Europapark.

I took some pictures while riding some of the rollercoasters, please forgive that they are quite out of focus some time

First rollercoaster we took was the Silver Star which is the biggest Rollercoaster in Europe. It has a height of 73m, a maximum speed of 130 km/h and enormous centrifugal forces up to 4g. Even Karen took the ride .

After this, we took one Rollercoaster after the other (the interesting ones). At midday we had lunch in some resturant and just after this we took the VINDJAMMER in Scandinavia.

It was very fun, especially Karens' and Leandros' performance in the evening. The participants were judged by the noise the audience made after the song, so I tried to whistle as loud as I could, but unfortunately it wasn't loud enough, so they didn't win the contest

I just updated the Information about the Sommercampus 2006 and uploaded the Slides and the Script of the PHP Course Dominik Benz and me gave together.
Here you can find more Information (Slides etc.) on the Course: PHP Courses (Sommercampus 2006)
Please also evaluate our Course on the Sommercampus Webpage: Evaluation of the Sommercampus

With the help of Niklas i just installed the new eLectures search engine.
It does not only index the Slides and the lecturnity Documents, but also the speech of the Lecturers.


See: eLectures-Search

The Option Indexes is disabled by default in the Servers Configuration. You can enable the Indexes Option for the Virtualhost portal.informatik/download.informatik by using a .htaccess File in your Directory with the following content:

Options Indexes

Limiting Access to the IP-range of the FAW or requiring user authentication is done the same way (this should be enabled in all Virtualhosts):

# Zugriff nur aus dem Uni-Netz erlauben
Order allow,deny
Allow from 132.230
Allow from 10.122.182
Allow from 10.122.182

# Zugriff durch Benutzername erlauben
AuthType Basic
AuthName "Titel der bei der Authentifizierung erscheint"
AuthUserFile /opt/local/apache/conf/users
require user someusername

# Beide Zugriffsmoeglichkeiten erlauben
Satisfy Any

You can look at the example File in /scratch/lectures/Template/.htaccess.example
The File /opt/local/apache/conf/users is writable only by users of the group elec-adm. So if you need to add a user to this user-file, contact electures@informatik to have it inserted.
