Creator of OCaml: Functional Programming, Formal Verification, Programming Languages | Xavier Leroy
Notas del episodio
Xavier Leroy (creator of OCaml) is an expert in compilers, formal verification of software and functional programming. This interview should be an approachable resource if you're curious about formal verification of software since I was learning that on the fly during it.
