Anil Madhavapeddy is an academic, author, engineer, entrepreneur, and OCaml aficionado. In this episode, Anil and Ron consider the evolving role of operating systems, security on the internet, and the pending arrival (at last!) of OCaml 5.0. They also discuss using Raspberry Pis to fight climate change; the programming inspiration found in British pubs and on Moroccan beaches; and the time Anil went to a party, got drunk, and woke up with a job working on the Mars Polar Lander.You can find the transcript for this episode  on our website.Some links to topics that came up in the discussion:Ron, Anil, and Jason Hickey’s book, “Real World OCaml”Anil’s personal website and Google Scholar pageThe MirageOS library operating systemCambridge University’s OCaml LabsNASA’s Mars Polar LanderThe Xen Project, home to the hypervisorThe Tezos proof-of-stake blockchainThe Coq Proof Assistant system
