Jack  worked out to run Qemu to boot a curious OS inside; Bluebottle . It is a system to be hosted by the ETH Zürich. I haven\’t heard of it yet.
Bluebottle is a powerful operating system based on the Active Object System (Aos) kernel. It provides a compact runtime environment for the Active Oberon language, which supports active objects directly, and enables the construction of efficient active object-based systems that run directly on the hardware.
Maybe it is due to its \”oldfashioned\” license  in times of Open Source why I havent noticed the OS yet. Kidding 😉 And no, Oberon isn\’t dead yet.
