In systemd we started to do more and more Varlink IPC (instead of or 9n addition to D-Bus), and you might wonder what that is all about. In this AllSystemsGo talk I try to explain things a bit, enjoy: https://media.ccc.de/v/all-systems-go-2024-276-varlink-now-
@pid_eins - Varlink reminds me of the IPC system we used at BlackBerry like 12 years ago. I guess the big difference was back then it was basically JSON with additional binary integer types. Not exactly like CBOR.
