My Daily Companions (last update: 13.06.2026)
I strive to use resources sustainably and consciously, opting to repair rather than replace items whenever possible. This philosophy is reflected in the list of my daily companions. The only exception is my iPhone, which is provided by my employer and replaced approximately every three years.
- Apple iPhone 17 Pro (2025), A19 Pro, 6.3", 256 GB
- Apple iPad Pro (2024), M4, 11", 1 TB, Cellular, Nanotexturglas
- Apple MacBook Pro (2021), M1 Pro, 1 TB, 16 GB RAM
- Samsung 4K Display
- Logitech MX Keys for Mac
- Logitech MX Master 3 for Mac
As a computer scientist, I don't just use my PC for browsing the web or writing letters only. I've been self-hosting smaller services, such as my password manager, for several years to keep my data secure. Last autumn, I took a significant step by replacing all possible services with self-hosted alternatives, including my own social media services and mail server.
