Trompeloeil Mocking Framework
Rob and Jason are joined by Björn Fahller to talk about the trompeloeil Mocking Framework for Modern C++ Unit Testing. Björn Fahller is a senior developer at Net Insight, and has been developing software for a living since 1994, mostly embedded programming for communications devices. Björn learned C++ from usenet and the ARM (Annotated Reference Manual) which was the standard before there was a standard. On a hobby basis, Björn likes to find silly solutions to non-problems and to explore effects of programming constructs. Outside of programming, Björn is a member of a small group thet brews beer together, and is also a member of a volunteer organization of aviators who help with things like search and rescue operations, forest fire monitoring, and storm damage assessment.

Memory Algorithm Proposal
Rob and Jason are joined by Brittany Friedman to talk about her accepted C++17 proposal which adds new algorithms and utilities for memory management and the process she went through getting the proposal accepted. Brittany Friedman is a dense collection of matter formed from molecules originating from inside the sun. She currently works as a programmer at Gearbox Software, where she weaves ones and zeroes into intricate little patterns. Her proposal for new memory management algorithms was accepted for C++17 and a bug that she filed against the C++ standard was fixed the way that she recommended. So basically you do not want to trifle with her.

Regular Void
Rob and Jason are joined by Matt Calabrese to talk about his Regular Void Proposal, template<auto>, the state of Concepts and more. Matt Calabrese is a software engineer working primarily in C++. He started his programming career in the game industry and is now working on libraries at Google. Matt has been active in the Boost community for over a decade, is currently a member of the Boost Steering Committee, and is a member of the Program Committee for C++Now. Starting in the fall of 2015, he has been attending C++ Standards Committee meetings, authoring several proposals targeting the standard after C++17, notably including a proposal to turn the void type into an instantiable type and a proposal for the standard library to introduce a generic algorithm for invoking standard Callables with argument types and argument amounts that may be partially calculated at compile-time or at runtime. He is also the author of the controversial paper "Why I want Concepts, but why they should come later rather than sooner", which may have contributed to the decision to not include the concepts language feature in C++17.

Kvasir
Rob and Jason are joined by Odin Holmes to talk about developing for Embedded Microcontrollers with C++ and the Kvasir library. Odin Holmes has been programming bare metal embedded systems for 15+ years and as any honest nerd admits most of that time was spent debugging his stupid mistakes. With the advent of the 100x speed up of template metaprogramming provided by C++11 his current mission began: teach the compiler to find his stupid mistakes at compile time so he has more free time for even more template metaprogramming. Odin Holmes is the author of the Kvasir.io library, a DSL which wraps bare metal special function register interactions allowing full static checking and a considerable efficiency gain over common practice. He is also active in building and refining the tools need for this task such as the brigand MPL library, a replacement candidate for boost.parameter and a better public API for boost.MSM-lite.
