Rob and Jason are joined by author John Lakos. They first talk about a funny C++ themed freestyle rap video commissioned by Victor Zverovich and a C++20 reference card produced by Bartlomiej Filipek. Then John discusses his new book, Large Scale C++ Volume I: Process and Architecture. In addition to discussing the book John shares some of his thoughts on allocators, modules, move semantics and contracts.

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.
