Learning C++ With C++26's Reflection

In this episode, Mathieu and Jason are joined by Ryan Keane to discuss his duck library, which allows polymorphism-like behaviour through reflection, along with his journey of learning C++ through exploring C++26's reflection mechanisms.

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].

Mathieu and Jason are joined by Kevin Carpenter to discuss all aspects of being involved with a conference: from regular attendee, to volunteering, to speaker, volunteer coordinator, and catering concerns. Kevin also shares some of his insights into how credit card processing works, along with some of the challenges he's encountered. In this episode Jason also gives the guest some homework assignments for future conferences!
