OCaml, Rust, C. - OCaml: my favorite (at least at the moment) functional programming language and a very good choice when writing compilers and static analyzers, which is my main research area. - Rust: a safe system programming language with a lot of good ideas imported from languages that I respect, and also with its own new things (i.e. borrow checker). I feel it's going to be a very important language in a few years. - C: although I predict that Rust is going to become very big, C will always be there. Though not my favorite language by a long shot (I'm way too bad a programmer to be expected to handle it properly), its importance can't be denied and being knowledgable in C will be a skill that will be useful and desirable for a long time.
