Read the primary article or dive into the live Hacker News thread when you're ready.
Implementation-wise, it uses the effect system of OCaml and apparently the multicore capabilities.
This doesn't work in the general case, e.g. for postfix and dovecot, and is only becoming more pertinent with short lived certificates. It would be great if the service manager could use these capabilities directly. I think GNU Shepard's integration with Guile Goblins and OCapN is a step in the right direction here: https://spritely.institute/news/spritely-nlnet-grants-decemb...
