Data races are nasty kinds of bugs; rare, hard to replicate and follow Murphy's law. Race detector find them? Learn how!

Data races are nasty kinds of bugs; rare, hard to replicate and tend to occur at the worst possible moment. Their effect is undefined, detection hard, almost impossible without expensive formal verification and static analysis tools...Or is it?

This talk focuses on ThreadSanitizer, a library for detecting race conditions at run-time. It originated in clang & C++ community and its use spread to go (-race), rust, java, and some other languages.
