Learn to diagnose realistic production failures in a distributed Typelevel streaming platform. Through a curated set of incidents, you will debug failures using telemetry and iteratively improve observability through manual instrumentation with otel4s, leaving with a practical mental model for telemetry-driven debugging in Scala.

Typelevel participated in the GitHub Secure Open Source Fund this year. This talk shares what we learned, what we are now doing to secure the Typelevel ecosystem, and how you can improve security in your own projects. We will also briefly discuss the requirements of the new EU Cyber Resilience Act.
