This talk is supposed to demonstrate a nice side-effect of being able to build old Nix expressions and even having a binary cache with the build artifacts available: for the data migration from a legacy project we had to debug a flash-based component. Even in 2021 where the Flash player is dead and unavailable it was trivial to revive this piece of old software with Nix (and web.archive.org).
