Communications: Email, Discord Assumptions: This course assumes you know the material in CMSC 330 and CMSC 216. In particular, you need to know how to program in a functional programming language like OCaml and be confident with some systems-level concepts like pipes and files and have a basic familiarity with Rust.

Spend more time learning the general way of programming in the different languages we cover than you do memorizing syntax.
