October 05Safety and Interoperability with Rust and C++
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 [email protected].

April 06Building a Compiler Inside the C++ Compiler with Daniel Nikpayuk
Daniel Nikpayuk joins Jason to talk about ccTMP, his C++17 template metaprogramming library that builds a functional type system at compile time by encoding bytecode as template parameters in continuation-passing style — letting the C++ compiler itself optimise away the interpretation layer. They also cover Daniel's path into C++, from typesetting Inuktitut in LaTeX to his longer-term goal of a multimedia programming language for Indigenous storytelling.
