RxCpp and Executors
Rob and Jason are joined by Kirk Shoop to talk about the RxCpp library and the future of Executors in C++. Kirk stumbled into an internship at Microsoft in the 90s that turned into contracting and eventually employment at Microsoft. At Microsoft Kirk sometimes pushed the compiler to its knees in the pursuit of libraries that prevent common errors. In 2013 Kirk joined Microsoft Open Technologies Inc to work on open source. Kirk began investing heavily in rxcpp in the belief that it is a better abstraction for async than the primitives commonly used. Now Kirk works at Facebook with Eric Niebler and Lewis Baker to build async range concepts and algorithms (with coroutines) into the c++ std library.

Since the last time he's been on CppCast he presented at multiple conferences about build tooling and simple code. In combining both, he created the build tool Evoke from cpp-dependencies and other smaller projects, leading to a simple to use build system presented at CppCon 2018. Earlier this year he presented its companion 2D Graphics library for absolute called Pixel at CppOnSea. He's active in both standards development as well as helping out with various things at conferences.

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.
