“The Unexceptional Exceptions"
summary
Claims that exceptions are “boring” and usable in small doses and shows how to make error handling correct, not scary: use RAII via unique_ptr/scope-guard to automate cleanup, prefer noexcept swap and destructors that never throw, distinguish basic vs strong guarantees (no leaks vs commit/rollback), repackage errors at system boundaries, and convert legacy return-code APIs at boundaries. Warns that pthread_cancel can interrupt anywhere (even noexcept/destructors) so thread cancellation requires special handling.
