In addition to graphic design, I am interested in physics, mathematics and computer science. I currently program in Bash, Python and Perl. Other programming languages such as C/C++, Pascal and Fortran are not unknown to me. I gained my first experience decades ago in machine language, assembler and Basic. Tools of all kinds should be useful, helpful and easy to use. The focus during programming is on ease of use. Thanks to the good documentation, I was able to make my first tool, which was previously only for personal use, available to the general public here. As errors cannot be ruled out despite all due care, I would be more than happy to receive helpful comments. While drinking sometimes a coffee I try to help translating packages here.This is good for relaxation.
