You know the feeling. You open a pull request on Monday morning. You ping the reviewer(s). You go to lunch. You come back. Nothing. You context-switch to something else. On Wednesday, the reviewer finally leaves a comment — a single one, on a minor detail. You fix it. You wait again. By Friday, the PR is still open, the branch is conflicting with master, and you’ve forgotten half of what the ag...

You have two overloads of g(). One requires A<T> for each element in a pack, the other requires C<T> — where C is a stricter concept that subsumes A. Both apply to the types you’re passing. The compiler should pick the more constrained version. But instead it complains about an ambiguous call. This is a limitation of how C++20 and 23 handle constraints that use fold expressions — f...

C++26 continues to fill the gaps in our type-erased callable wrapper story. We already had std::function since C++11 and std::move_only_function since C++23, but there were still missing pieces. Now we’re getting two new additions: std::copyable_function and std::function_ref. What’s wrong with std::function? std::function has served us well, but it has two well-known issues. First, it can ...

Undefined behavior (UB) in C++ is one of the hardest categories of bugs to deal with. It can silently corrupt memory, cause crashes far from the actual mistake, or — worst of all — just happens to work on your machine. A significant share of UB in real codebases comes not from exotic language features, but from basic misuse of the standard library: accessing a vector out of bounds, calling fron...

I recently stumbled upon the TRIGGERnometry podcast, which brands itself as a “free speech show”. It’s hosted by two (former) comedians, Konstantin Kisin and Francis Foster. I usually listen to these podcasts while working out, and what I really appreciate about them is that they host people with very different views and always have respectful, unfiltered discussions. Yes, honest debate without...
