Welcome to the mind vault, a collection of references, notes, and insights I’ve gathered and refined throughout my life. While most of the vault is private, the pages you see here are ones I’ve specifically chosen to share publicly.
My goal in publishing is to become a better writer, by lowering my barriers to publication, sharing more of my thinking and receiving feedback on my writing.
You can find my more writing and additional specific content at these locations:
- Snoffeecob: a blog focused on brewing and tasting specialty coffee.
- Hashbang.nl: A blog covering technology, homelab, devops, AI, and software development.
- TederMusic.com, Dedicated to my live electronic music production and performances.
Feel free to explore!
