I'll be speaking at C++Now about functional composition beyond monads! I hope to see you in Aspen, too — C++Now is by far the best C++ conference.
We are pleased to announce 50 outstanding presentations from C++ experts that will be taking place at C++Now 2026 from 4th - 8th May Read the full announcement - cppnow.org/announcements/202… #cpp #cplusplus #programming #coding

Next week at @cppnow I'm giving two talks: First, my "Overenginering max(a, b)" talk, which is just fun metaprogramming. Then, a new talk "Missing (and future?) range concepts" which is turning out really great, I can't wait to give it: schedule.cppnow.org/session/… #cpp #cplusplus

I published my trip report about the Hagenberg meeting last week: think-cell.com/en/career/dev… I was wrong about the potential for dangerous optimizations with contracts and ODR. The behavior is not allowed; the blog post has been updated. #cpp #cplusplus
