cpp.chat

cpp.chat is a conversation show about C++, built around two regular voices, Phil and John, and whoever they have brought in from the C++ world. Every episode has the same setup, and the setup is a joke. In most intros here Phil opens with a different adjective, calling the show an 'almost regular', 'strongly guaranteed', 'solid' or 'conceptual' look at the language, and then passes to John. John reads a disclaimer from somewhere else entirely: a pet-product warning, a notice that much of the material, recipes included, comes from antique sources mostly over a century old, a reminder that past performance does not guarantee future results. In one episode the follow-up question is what pet they have on today. Then the talk turns technical and gets specific fast. In 'Did You Really Learn from All the C++ Mistakes?', one stretch lays out a gap in concepts: a constraint catches a caller whose type lacks addition, but a template body that quietly uses multiplication goes unchecked until instantiation. The original design credited to Doug checked both sides. 'Required to Warn You, Unless It’s Hard' comes back to concept checking and to the version once called concepts light. 'I Can't Believe I'm Here' explains std::forward_like, which forwards a member with the value category of the object it belongs to, and ties it back to deducing this. That episode also runs under a different banner, 'No CPP Diagnostic Check Required', which its closing calls something of a one-off. 'The Answer Is, It Depends' has a real back-and-forth over the open-closed principle, with one voice insisting it means extending a library without touching its code, not just deriving from base classes. The show also looks at how C++ gets made. In 'The Curse of Backwards Compatibility', a guest describes spending about half a year setting up a group in Sweden to bring people into WG21 work, and why a local group matters when anyone with a Zoom link can join a meeting. 'The Future of C++ (KDAB interview)' uses a different format: it is a panel John joined for KDAB, which KDAB then offered to cpp.chat to release. It covers C++ coming out of Bell Labs and AT&T without any company ever championing it, the Standard C++ Foundation and its backing from Microsoft and Google, and a panelist's book about the language's revival, subtitled 'The Beast is Back'. There are tangents too. One speaker apologises for derailing things after an aside about C++ programmers going back to commuting and wanting podcasts for the trip. The show is candid about its gaps: one intro jokes about this week's or month's or maybe year's guest, and the same episode admits it has been a while. One closing makes a pitch for C++Now registration. Most goodbyes end with everyone repeating 'safe coding', and one adds 'you're gonna need it'. For template checking, start with the two concepts episodes. For the language's history, try the KDAB panel, and for a design argument, try 'The Answer Is, It Depends'.
