System software goes weird

November 5, 2019

System software has been a monoculture of C and a land of monoliths, but a new wave of open source system software has started to appear, in languages such as Rust, Go, Haskell, OCaml, and Lua. These projects are developing new sorts of applications and introducing new people to systems programming. Justin Cormack explores what's going on, where it's useful, and the new paths it's leading us down.
