https://www.youtube.com/watch?v=GWr4iQfc0uw Abstract of the talk @ ICFP 2020 Programming language implementations have features such as threads, memory management, type safety, and REPLs that duplicate some of the work done by the underlying operating system. The objective of hosting a language on bare metal is to unify the language implementation and operating system to have a lean system with no redundancy for running applications. This seems to be the OS: https://github.com/udem-dlteam/mimosa The Mimosa operating system consists of a minimal kernel built on C++ and Scheme. It contains a Scheme implementation of a hard drive (ATA) driver, keyboard (PS2), serial (8250 UART), FAT32 filesystem and a small real time clock manager. The project was built to experiment with developement of operating system using a high level functional language to study the developement process and the use of Scheme to build a fairly complex system.
