Learn systematic debugging approaches through this conference talk from Copenhagen Developers Festival where Maciej Rząsa demonstrates how to apply scientific methods to software troubleshooting. Explore proven techniques used by scientists - observation, hypothesis formation, and experimentation - applied to real-world debugging scenarios. Through case studies involving non-deterministic tests, production issues, and CI infrastructure problems, discover how to approach complex bugs methodically rather than through frustration and guesswork. Master practical strategies for scaling debugging practices across development teams while building resilience against challenging software issues. Gain insights into transforming debugging from a source of frustration into a structured, scientific process that yields reliable results.
