Topics

The current topic areas of the series. Each topic has its own author, with a distinct domain focus and a recognisable voice — three authors in total.

Open-Source adoption and platform architecture

When do you wrap a component, when do you build it yourself? How do you pin versions without drowning in maintenance? How do you keep the companion layer from quietly becoming an in-house build? Mira Halbach, platform engineer in Berlin, writes on these questions.

OSS Choice with a Matrix

Six axes for honest wrap-or-build decisions, with a worked-through ADR and a cheatsheet to pin on the wall.

Mira Halbach · Releases autumn 2025

CI/CD tooling and build pipelines

Linting without MegaLinter, image pinning without regret, CI templates for the mid-market. Jonas Veit, DevOps engineer in Hamburg, writes on these topics.

Linting in Layers

Four layers instead of one mega-linter — language, format, convention, domain. Each individually pinnable, all running in parallel. Includes a concrete Postgres-operator repo as a worked example.

DevSecOps and EU sovereignty

GDPR in concrete terms, identity without in-house builds, vulnerability triage. Anouk Schierl, security engineer in Munich, writes on these topics.

Six patterns for clean data protection in code — data minimisation, consent, PII zones, erasure, audit, and cross-border discipline. With three diagrams and a worked-through onboarding example.
