Operating Systems

Operating systems run your computer! There are lots of innovative OS projects but only a few are really used. A few more than those have some interesting ideas. [Expanded Main Page - OSDev Wiki] has tons of resources on building an operating system.



Aside from Linux, Windows, MacOS and derivatives...

  • [Qubes OS] :: An operating system that isolates every application and device on the computer, granting permission to each only when necessary. Many journalists and security professionals rely on this.
  • [WhoNix] :: An operating system designed to completely sandbox your activity inside of a virtual machine.
  • Plan9 :: Defer to [Devine's notes on the subject] .

  • [Junos OS]
  • [Spectrum] :: An OS modeled after Qubes, but making full use of the Nix reproducible build system, and dedicated to supporting mainstream x86-64 hardware.
  • SmartOS :: combines opensolaris tech with linux kvm virtualization. has zfs. contributed to illumos project



  • LineageOS ::

The most popular alternative Android operating system, built off of CyanogenMod.



  • e :: An operating system designed to function efficiently on older, refurbished devices. Built on LineageOS.
  • NixOS Mobile :: A full port of NixOS to a mobile platform. It's built on top of many previous efforts and relies on a tool to convert GTK applications to mobile equivalents.


[I got my Gameboy emulator running in my OS! : osdev]. This is so inspirational. I love it. I would love to play this game boy game on this operating system. It sounds so fun and satisfying to have made and to use a stack like this!
