2. Rafael Lopes, Concurrency Testing in Go: Exploring testing/synctest in Go 1.24 [45 min; 18:00 - 18:45]
Go 1.24 introduces testing/synctest, a powerful new package designed to make concurrency testing safer and more deterministic. In this talk, we'll dive into how synctest works, explore its practical use cases, and see how it can help catch subtle race conditions in real-world projects. Whether you're maintaining critical systems or building scalable apps, this session will give you the tools to test concurrent code with greater confidence.

4. Robert Pająk, A tale of designing OpenTelemetry Go Logs [45 min; 19:15 - 20:00]
This talk covers the methodical process used to design a high-performance, specification-compliant logging API for OpenTelemetry Go. It explores the complete journey from initial prototypes to production-ready implementation, highlighting key challenges like achieving zero allocations on the hot path, balancing user-friendliness with performance, and designing APIs that evolve gracefully as specifications change. The presentation demonstrates an evidence-based approach where every design decision was validated with benchmarks, resulting in many rejected alternatives and comprehensive documentation of the final design.
Robert is currently a Senior Staff Software Engineer at Splunk a Cisco company and a maintainer of OpenTelemetry Go.
5. Lightning talks [30 min; 20:00 - 20:30]
