After I finished my Time in C++ series, a reader asked a seemingly simple question: “What is the portable way to extract the year, month, day, hour, minute, and second from a file’s modification time? I tried, and I couldn’t get it to work reliably on macOS and Windows.” Fair question. You call std::filesystem::last_write_time(), you get back a time point, and you want the calendar compon...

A few months ago, I wrote about finding joy in programming in the age of AI. In the personal discussions I’ve had with fellow developers — both before and after that article — one thing keeps striking me. Most people don’t argue. They just say: yes, that’s exactly how it feels. But a question kept coming up in those conversations: why does it feel this way? Not in the philosophical sense — I c...

A few weeks ago, I wrote about what happens when a destructor actually throws and why it is a dangerous idea. One of the readers commented that he was once in a situation where he had to propagate an exception from a destructor. But as a destructor cannot safely throw and it also cannot return any value, he needed a better solution. And that solution was std::exception_ptr. Let’s look into wh...

constexpr has come a long way since its introduction in C++11. Back then, constexpr functions were extremely restricted and could essentially contain only a single return statement. C++14 relaxed those restrictions, allowing local variables, loops, and multiple statements. C++20 was another major milestone, bringing support for constexpr dynamic allocation, enabling types such as std::string an...

Once again, I got the chance to come to Folkestone, UK. I think this was my fifth time, but the first one at ACCU On Sea. Yes, there is no more C++ On Sea, there is no more ACCU in Bristol — they got merged into ACCU On Sea. The venue is the same as C++ On Sea, many organisers are the same, but of course there are also changes. The conference chair is no longer Phil Nash but Guy Davidson. Th...
