A focused selection of essays and guides: sovereign digital infrastructure, AI in production, product liability for developers, philosophy of technology, and my conference talks. Most topics feed directly into my consulting and workshop offers.
Before there were stochastic parrots, there was an XML dialect that faked conversation one tag at a time — and won the Turing test's most decorated prizes doing it. AIML, its Graphmaster, the recursion nobody can name, and what large language models quietly re-learned from the honest kind of liar.
Two words cut into stone at Delphi twenty-five centuries ago — the oldest command in the Western tradition, and the one machines still cannot execute. How to pronounce it, what it actually meant (not what we assume it meant), Socrates' hostile takeover of it, and why every hallucinating language model is a fresh proof of the maxim.
A hands-on exploration of Matrix room discovery: querying public room directories via the Client-Server API, what works anonymously and what doesn't, and a curated list of rooms worth joining for DevOps and self-hosting folks.
The BSI published C5:2026 in March — from June 2027 the catalogue becomes the recommended baseline for cloud audit periods. What NIST CSF 2.0, CSA CCM, and the new catalogue mean for vendors serving German enterprises and the public sector.
One idea runs from Pythagoras' ratios, through Plato's Timaeus and Kant's wallpapers, to Noether's theorem and the Lie groups of the Standard Model — and now sits inside every neural network as equivariance. A short philosophy of symmetry as invariance under transformation, and why machines finally made the a priori empirical.
The two services almost every application needs, tuned instead of defaulted: production-tuned PostgreSQL (shared buffers, WAL compression), Redis with AOF + RDB persistence, and a scheduled backup job
