#KubeCon has a nice track called #Contribfest where maintainers can meet with (prospective) contributors to solve problems.
I randomly popped into the #OpenFeature slot w/o knowing anything about it (open standard for feature flags).
Although I couldn't contribute to any issue, maintainer Todd Baert was helpful and patient in assisting me to get a sample Spring Boot app running locally with #OpenFeature & #flagd.
A memorable encounter.
Also got a shirt, now feeling obliged to give back lol
