Concurrency Testing in Go: Exploring testing/synctest in Go 1.24
Host: Rafael Lopes
Info: 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.
Rafael Lopes is a software developer with more than 10 years of experience, currently having fun with Go and trying to keep production alive. Fan of DevOps, Infra as a code and all Kubernetes-related stuff.

Concurrency - what the hell is going on there
Host: Mateusz Szczyrzyca
Info: Concurrency is a complex topic and during this talk I've got limited time. In this time we little scratch the surface about basics. Even so, I show some problems with solutions and good practices, some of them may be controversial. Presentation is for those who want to know more about some concurrency issues in Go and how to cope with them and make your app more clean in terms of what's happening when you decide to use concurrency in your code.
Mateusz Szczyrzyca is a software engineer, focused mainly on projects in Go and Rust programming languages, who loves open source and to explore hidden secrets of programming languages and to chase last milliseconds in performance benchmarks. Website: https://devopsiarz.pl.
