I've learned something today:
- When basing your context on another context you have to make sure the original context is not being cancelled before you can make proper use of it. (cf. https://github.com/fluxcd/notification-controller/pull/408)
- You have to be careful with your producer configurations when dealing with Apache Kafka or you will encounter errors at the least convenient time possible (for example during christmas time).
- Defer, Panic and Recover are Go's idiomatic way of handling errors and cleaning up resources.
- In Go a stack trace is a report of the active function calls at a specific point in time. It is often displayed when an unexpected error occurs and provides a roadmap of the execution path leading up to the error. Hence, it is an invaluable tool for debugging.
- Google Berlin's catering takes the 2-Hour-Rule very seriously and discards any perishable food left out at room temperature for more than 2 hours.
