Kehrwoche: What Swabian Cleaning Teaches About Technical Debt

Published on 1/9/26 11:00 am by Martin Stühmer

Kehrwoche—a Swabian cleaning tradition—is scarier than breaking the build on Friday afternoon. At least the build doesn’t remember next Tuesday. Mrs. Schmid from the second floor does, and she remembers well. What does a weekly cleaning schedule in southern Germany have to do with technical debt? More than most software teams want to admit.

Alphabet Soup: The Format Buffet Nobody Ordered

Published on 1/8/26 5:00 pm by Martin Stühmer

Developers wanted one format. We got twenty. CSV mangles data, XML drowns in tags, JSON forbids comments, YAML punishes spaces. TOML tried fixing it. TAML went minimal. TOON optimized for AI. CCL brought category theory. Result? Five formats per project, three parsers, and debugging why NO became false. AI can’t save us either. Welcome to format hell.

Why Real Professionals Will Never Be Replaced by AI

The elephant everyone ignores: AI can generate code faster than you can type. GitHub Copilot autocompletes entire functions. ChatGPT builds APIs from prompts. Typing is dead. So why will real professionals never be replaced? Because “vibe coding”—describe what you want, ship what AI generates—is a productivity illusion that collapses spectacularly in production. When code generation becomes trivial, understanding what that code costs, where it fails, why it breaks under load becomes everything. AI generates syntax. Professionals understand execution, failure modes, operational cost, and production consequences. The differentiator isn’t typing speed—it’s mastering the feedback loop: write code, watch it fail, understand why, refine thinking. This discipline can’t be automated. Prompt engineers generate code. Real professionals ensure it survives contact with reality.

2025 in Review: The Year .NET Stopped Lying to Itself

Published on 12/30/25 5:00 pm by Martin Stühmer

Forget the hype—2025 was when .NET tooling finally stopped pretending complexity doesn’t exist Three tools won by being honest: Aspire exposed topology, TUnit killed flaky tests, Testcontainers made infrastructure real
