Altough you might think so this is not the end of the internet...

There are some things to find on my page, I will give some hints below but through the menu on the left even more is available. I also have a blog, but I want to keep that one kind of anonymous so I won't link it here:-).

If you want to contact me, use arnold at arnoldarts dot de. You can see whats new (and promoted) following this link.



The Location: A normal room. Well, perhaps not a normal room but a normal practice room filled with lots of musical instruments, keyboards, computers, amplifiers with speakers and such.

The Parties concerned: Several musicians playing different instruments but - sadly - no drummer. The computer will take its place as many times before.

The Occasion: The musicians are gathered for a small jam-session. No well-known songs to play, maybe not even a predefined song structure.


This is a little piece of software to convert C++-programmlistings to a file you can input in an LaTeX-document.

I wrote it primarily for my bwinf-project-documentation, because we had to include the source-code and I wanted it all printed in the same style. After BWInf I had time to work on C++2LaTeX and made it stable and usable for the rest of the world.


Kde's value oriented taste evaluation

the problem

Every day I download new nice pictures from kde-look.org. Some of them are really good, some are nice but not really outstanding.

So if I want to have these new images in the list for the background I have to go to the right configuration-page, and select the new pics for adding to the list. - Sounds complicated?


It aims to be a small game for audio-techs that plays a sinus-frequency and displays buttons for the 31 freqs of a normal master eq. Now you have to select the right frequency that is played. Of course reaction-time and error-rate will be evaluated.

CloudKnowledge: installation and short tutorial

If the easy_install tool is installed (in ubuntu its in the "python-setuptools" package), installation is really easy:

easy_install http://www.arnoldarts.de/files/cloudknowledge-0.1.tar.gz

Once that is run (preferable as root), you can start using the apps that show how it works.

Start cloud-server on one console and watch its output.

CloudKnowledge: introduction

The first version is ready for download and testing. See here for installation instructions and a first tutorial.

Thinking about self-configuring redundant network-storage I figured that there should be versions of the data. And somehow the network has to remember the last version number.


The idea came while thinking about the design for the doors of my closet: Paint the doors like one of the famous pictures of Piet Mondrian!

The needed steps are:

  1. collect pics from some of his works...
  2. analyse them with a little app, count the pixels per color and perhaps the thickness of the lines
  3. invent an algorythm to create such pictures, at least distribute the colors the same way

Lets see how far I get...


Why I use gpg

As I am a bit concerned about the security of the emails I sent (and get) I am using GPG to sign and possibly encrypt the messages I sent. You can download my public-GPG-key here or from pgp.uni-mainz.de or pgp.mit.edu.

My ID is C0E31F1D with the fingerprint: 46D5 6D01 D6D5 4D08 15DC 9C59 B982 CBD5 C0E3 1F1D.
