Have you ever debugged a little too hard and reached the Go runtime? If so, and if you continued digging deeper, you may have reached the unwinder - an internal runtime type responsible for unwinding stack frames. In this talk we’ll understand exactly what that means, how it works, and where it’s used. This is an opportunity to learn about the internals of the language you code in and discover how to improve performance with knowledge of stack resizing, GC, and more.
