It's crucial to thoroughly reproduce a bug before attempting to fix it - This can be often trickier than engineers think. Here are the core points from the lesson:
- Reproducing a bug requires systematically testing different versions, languages, devices, network conditions, experiments, and user paths—not just trying once and giving up
- Bugs might appear intermittent or path-dependent, so multiple attempts and thoughtful investigation into what wasn’t captured in the bug report are essential
- Understand the broader categories of software failures (functional, usability, integration, concurrency, security, performance, user error) so you can better diagnose the true underlying problem
- Strong debugging starts with deeply understanding when and why the bug occurs, forming the foundation for prioritizing and fixing it effectively
