I earned my degree in physics from Humboldt Universität zu Berlin, with a specialization in High Energy Physics. As an experimental physicist, I contributed to major research efforts at DESY, CERN and facilities in Russia, focusing on the analysis of experimental data using large-scale computing systems. Early programs were developed primarily in Fortran, supplemented by Assembler for performance optimization, and later evolved into C++ solutions.
In 1991, I assumed leadership of the computer center at DESY Zeuthen, overseeing the transition to a modern UNIX-based infrastructure with distributed computing capabilities. The adoption of Linux commenced in 1995, followed by the installation of custom-designed, massively parallel computers optimized for Quantum Chromodynamics simulations starting in 1997. I also spearheaded workflow automation initiatives within the center, leveraging Perl as the primary scripting language.
Some years ago, I authored a quick reference manual for Linux user commands, which still might be of some value. Additionally, I developed lesspipe.sh, an advanced script enhancing the less text viewer, which I continue to maintain and expand. Supporting scripts further improve TAB completion functionality for both Bash and Zsh shells.
More recently, I have explored the creative assembly of marble run tracks using Gravitrax® alongside children. To facilitate documentation and replication, I devised a dedicated notation system and implemented a local application for storing, visualizing, and retrieving these configurations.
Currently I lead the KulturRaum Zwingli-Kirche e.V., where I integrate my technical expertise with a commitment to cultural and community initiatives in Berlin.
