Opening Keynote Oct 11 by @lefticus explores resilience of #cpp with strong types. Many bugs are avoided w/ strong types yet using stronger types often is a burden to developers. He examines why stronger typing is useful and techniques to make them easier. store.ticketing.cm.com/cppun…

Early-bird tickets end in 14 hrs. Our closing keynote by @Inbal_l covers an innovative area of #cpp : reflection. With a proposal for reflection in C++26 (“std::meta” namespace) supported by WG21, we can imagine a new world of possibilities. store.ticketing.cm.com/cppun… #cplusplus

Join @phil_nash Oct 11 for a journey through type categories and learn how to properly handle lifetime management in #cpp as the language has evolved. Register: store.ticketing.cm.com/cppun… Learn more about all our speakers announced so far: cppunderthesea.nl/
Join us on Oct 11 for a deep dive into Boost.Geometry, a popular Boost library. Explore its design with C++20 concepts, tag dispatching, and traits. See how these apply in large-scale projects. More info: store.ticketing.cm.com/cppun… #Cplusplus #Boost #cpp
Delve into high-performance computing, learn GPU constructs to maximize performance and efficiency, and see it coded live with a SYCL kernel. Learn blocks, work items, work ranges, memory barriers, fences, occupancy levels, and more! Register: store.ticketing.cm.com/cppun… #cpp #gpu
