Rob and Jason are joined by Artem Dinaburg and Ryan Eberhardt. They first talk about a new version of CMake that was just released, an interview with Bjarne Stroustrup and another month of new ISO papers. Then they talk to Artem and Ryan who talk about fuzz testing, including a new fuzz testing project being worked at Trail of Bits to enable fuzz testing on the GPU.

Mathieu and Jason are joined by Jon Bauman to discuss safety and interoperability between Rust and C++. They dig into what "safety" really means (there are several categories of safety), what can and can't be guaranteed, how C++ could become a memory-safe language, and the challenges of making Rust and C++ work well together. Jon is currently looking for sponsorship to continue this important work. You can contact Jon via Joncppcast@shumi.org.
