December 15, 2023SIMD
Matthias Kretz joins Phil and Timur. Matthias talks about SIMD, including what it is, how it works, and what its useful for. We also discuss his proposal to introduce SIMD vocabulary types and functionality into the C++ standard and how it relates to what was in the Parallelism TS.

December 01, 2023Catch2 v3 and Random Numbers
Martin Hořeňovský joins Timur and Phil. Martin returns to talk about v3 of Catch2 and how it is different to v2. We also revisit the topic of random numbers and how Martin is still working on portable distributions and why that is important to testing and other domains.

October 20, 2023Physical Units and a System of Quantities
Mateusz Pusz joins Phil and new guest co-host, Anastasia Kazakova. Mateusz talks to us about his physical units (and quantities) library, mp-units, why v2 is a complete redesign compared to the previous version, and how incorporating a system of quantities is so central to this new design.

September 15, 2023AI and Random Numbers
Frances Buontempo joins Phil and returning guest co-host, Matt Godbolt. Frances talks to us about her new book on modern C++ as well as her the topic of her previous book on machine learning. We discuss the differences between LLM-based AI and more statistical approaches, as well as where random numbers fit into all this and the limitations of their current support in C++.
