You know it, right? Don't despair. We can leverage centuries-old practices used by scientists. Observation, hypothesis, experiment - rinse and repeat. This method worked for me in real cases. I'll tell about a non-deterministic test, a nasty production issue, and malfunctioning CI infrastructure. This talk will show you how to debug without frustration. You'll see practices hardening you for a fight against complex bugs. Finally, you'll know how to scale debugging to the entire team.
