I just attended the C++ Under the Sea 2-day conference. I really enjoyed it. Watch out for talks from Hana, Matt and Kevin Henney. Really good keynotes

Matt presented his v4 version of this ZX Spectrum emulator: https://github.com/mattgodbolt/specbolt

Both Kevin Henney's and Hana's talks were new; at least I haven't seen a version of them before. These keynotes were really, really good. Hope it comes on YouTube soon.

Personally, I was a bit let down by talks from people who work for AI companies. The talks became more like a product user guide than anything to do with C++ or Programming.

Overall, an amazing conference. If you are in or around the Netherlands, you should plan to attend.
