Showing off the first version of Munal OS, an experimental operating system I have been writing in Rust on and off for the past few years.

https://github.com/Askannz/munal-os

It's an unikernel design that is compiled as a single EFI binary and does not use virtual address spaces for process isolation. Instead, applications are compiled to WASM and run inside of an embedded WASM engine.

Other features:

* Fully graphical interface in HD resolution with mouse and keyboard support

* Desktop shell with window manager and contextual radial menus

* PCI and VirtIO drivers

* Ethernet and TCP stack

* Customizable UI toolkit providing various widgets, responsive layouts and flexible text rendering

* Embedded selection of applications including:

  * A web browser supporting DNS, HTTPS and very basic HTML

  * A text editor

  * A Python terminal
