January 17, 2019Boost 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!'.

January 03, 2019ISO 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.

December 21, 2018Semantic Merge
Rob and Jason are joined by Pablo Santos from Codice Software to discuss Semantic Merge, Plastic SCM and more.

Prior to entering start-up mode to launch Plastic SCM back in 2005, Pablo worked as R&D engineer in fleet control software development (GMV, Spain) and later digital television software stack (Sony, Belgium). Then he moved to a project management position (GCC, Spain) leading the evolution of an ERP software package for industrial companies. During these years he became an expert in version control and software configuration management working as a consultant and participating in several events as a speaker. Pablo founded Codice Software in 2005 and since then is focused on his role as chief engineer designing and developing Plastic SCM and SemanticMerge among other SCM products.

November 29, 2018TDD, BDD, Low Latency and CppCon
Rob and Jason are joined by Lenny Maiorani from Quantlab to discuss high performance computing, pair programming, volunteering for CppCon and the site of next year's CppCon.

Lenny has been using C++ off and on since 1995. Since graduating from SUNY Plattsburgh with a degree in Computer Science, he has been working at startups focused on high-throughput applications. About 2 years ago he joined Quantlab and discovered a different type of high-performance computing in low latency systems. Lenny lives in Denver, Colorado with his wife Lexey and their dog. He can be found hiking in the Colorado mountains while thinking about container access patterns and wondering if std::map can be renamed to std::ordered_map.
