Wireless comms nearly always focus on the EM spectrum- RF, microwave, even laser. But what about sound? Motivated by Dragos's badBIOS work, richo sat down to reimplement a subset of the original capabilities at a high level in userland. Having already produced the Groundstation framework for distributed communications, the next logical step was to produce an audio bridge, the result of which is that nodes with working sound hardware can communicate structured data when physically proxmiate, without any other shared state.
Richo likes his ducks flat and his instruction sets reduced. Fueled by a fascination with high order systems, he's worked on projects like the Rust compiler and the Voltron debugging system. His 9-5 is security engineering at Stripe, but he can be reliably be nerdsniped by a discussion about static analysis, distributed systems, or world travel without going insane.
