"Nobody stops in to check on you. They check on the project. There’s also nobody standing up and saying, ‘hey, thank you for the good work you’re doing to remediate this issue.’"
The harsh truth: maintainers give their spare time, yet positive feedback is rare.
Appreciate who is behind the code. 💛

I never imagined GitHub would ask me to speak about #Log4Shell.
But it happened.
@github.com asked me to share the story as I lived it, for the benefit of users of #opensource. How could I say no?
I hope it helps build a more secure future.
No more Log4Shell.

One small library affecting billions of systems.
Log4Shell was the biggest security vulnerability of all time.
