In this bonus episode, Luca responds to a thoughtful listener question about repository granularity in embedded development projects, particularly in safety-critical industries. The listener describes their approach of using separate repositories for different work products and even considers micro-repositories for different code components. Luca shares his perspective on why this approach makes him uneasy, suggesting it might overcomplicate development processes. He advocates for fewer repositories - ideally a monorepo approach - and explains how configuration management can be handled effectively within a single repository using feature flags, tagging, and CI pipelines. Luca reflects on how his own thinking about repository strategy has evolved over the course of the podcast, moving away from branch-based development toward trunk-based development with appropriate safeguards.
