Daveed Vandevoorde, a contributor to getting Reflection into C++26, joins hosts Phil and Timur. They discuss the implementation of reflection in C++26, the competitiveness of proposal in C++, and the potential of reflection to eliminate separate scripts.

Ville Voutilainen from The Qt Company and C++ standard committee discusses integrating modern C++ features with Qt. Topics include Modules, Sender/Receiver, Qt framework, and C++ 20/23 support. Also, updates on C++ 23 standard release delay, Boston C++ meetup, and C++ Now conference.

Phil and Timur are joined by ... Timur and Phil for a Holiday Special. We look back on the last year, discuss the news, and talk about what we're working on.

Matthias Kretz, a contributor with expertise in C++ programming, delves into the fascinating world of SIMD (Single Instruction, Multiple Data). He explains how SIMD works and its significant advantages for enhancing computing performance. The discussion includes his innovative proposal to introduce SIMD vocabulary types to the C++ standard, addressing challenges like compiler optimization and debugging. They also touch on the complexities of using SIMD with custom data types and the impact of efficient data structures on performance.

Martin Hořeňovský talks about Catch2 v3, portable distributions, and the importance of testing. They discuss random number generation inconsistencies, testing challenges, and potential alternatives for Rust developers.

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.

Frances Buontempo, an expert in modern C++ and machine learning, joins the hosts to discuss her new book and the topic of her previous book on machine learning. They explore the differences between AI approaches, the role of random numbers, and the limitations of random number support in C++.

Abbas Sabra joins Phil and Timur. Abbas talks to us about static analysis, the challenges - and benefits - of analysing C++ code, and a new feature from Sonar that can scan public repos with zero config.

Mark Gillard, guest co-host Jason Turner and Timur discuss reflection, SIMD, and Mark's library soagen, a structure-of-arrays generator for C++. Topics include Low Latency C++, STL, modules in Flux, pycmake, data-oriented design, toml++, and experiences with open source projects and C++ committee meeting.
