- C++ On Sea 2025 in Kent, UK 2025
We're excited to sponsor C++ On Sea 2025 as the official video sponsor, helping bring high-quality recordings of all talks to the global C++ community.
Held from June 23–25, 2025, in Folkestone, UK, C++ On Sea is an international conference for the C++ community, featuring top speakers, in-depth technical talks, and a vibrant exchange of ideas about the language and its ecosystem. This year, think-cell is also contributing to the program with two of our team members presenting.
Sebastian Theophil will speak on Tuesday, June 24, from 09:15 to 10:15 BST. His talk, To Err is Human: Robust Error Handling in C++26, presents a practical strategy for handling errors in modern C++. He will explore when and how to handle errors effectively, highlighting new and upcoming language features such as std::stacktrace
, std::expected
, contracts, and library hardening to help developers write more robust and maintainable software.
Later that morning, from 11:00 to 12:15 BST, Jonathan Müller will present Missing (and future?) C++ range concepts. In his session, Jonathan examines categories of ranges that aren't currently well-supported in C++, such as infinite, approximately-sized, and noncontiguous ranges. He will also introduce ideas for future improvements, including a push-based for_each_while()
customization point that could unlock more powerful and efficient range-based programming.
We’re proud to support C++ On Sea and contribute to the ongoing dialogue around modern C++ development. Learn more at cpponsea.uk.
