Hi, I am a passionate techie and like everything around technology, especially Linux, Python and Open Source as well as security related topics.

This site is my “Sandchaschte” for new things and projects.
If you wonder about the special domain: “Sandchaschte” is swiss german and means “sandbox” - so simple.

From time to time when I have some to spare a a blog post appears… 🦄


If you want to contact me, use the social links or drop me a line.
For security relevant topics use my GPG-Key:


I value data protection and respect the privacy of others. To run the blog, however, some technical tools are needed to collect statistics or provide features:

  • Comment function: Isso, self-hosted
  • Statistics: Freshlytics, self hosted, statistics about page views (without tracking information as in Matomo)
