Boost DI and SML
Rob and Jason are joined by Kris Jusiak to discuss [Boost].DI and [Boost].SML libraries. Kris is a C++ Software Engineer who currently lives a couple of doors down from CppCon 2019. He has worked in different industries over the years including telecommunications, games and most recently finance for Quantlab Financial. He has an interest in modern C++ development with a focus on performance and quality. He is an open source enthusiast with multiple open source libraries where he uses template metaprogramming techniques to support the C++ rule - "Don't pay for what you don't use" whilst trying to be as declarative as possible with a help of domain-specific languages. Kris is also a keen advocate of extreme programming techniques, test/behaviour driven development and truly believes that 'the only way to go fast is to go well!'.

ISO Papers and Merged Modules
Rob and Jason are joined by Isabella Muerte to discuss her experience presenting multiple papers at her first ISO meeting in San Diego and her thoughts on Merged Modules. Isabella Muerte is a C++ Bruja, Build System Titan, and an open source advocate. She cares deeply about improving the workflow and debugging experience the C++ community currently has and is designing and implementing an experimental next-generation build system called Coven based on ideas mentioned in her CppCon 2017 talk "There Will Be Build Systems", while also simultaneously ripping CMake apart and putting it back together again with a library titled IXM. She recently launched aliasa.io, a small URL routing service intended for the CMake FetchContent module. She enjoys playing Destiny 2, acquiring tattoos, and is currently trying to master the five elements of earth, wind, water, fire, and gun (but she makes no promises). She bows to no entity but the terrifying Eldritch Daystar we call the "sun", and hopes to one day own two german shepherds named Rip and Tear.
