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](https://wiki.osdev.org/Expanded_Main_Page) has tons of resources
on building an operating system.

# Projects

## Desktop

Aside from Linux, Windows, MacOS and derivatives…

[IlluminOS](https://illuminos.org)  
An operating system that claims to provide advanced system debugging, a
next-generation file system, networking and visualization.

Windows 10 with the crap removed

[DawnOS](http://gerigeri.uw.hu/DawnOS/)  
An operating system built on the [subleq](http://mazonka.com/subleq/)
higher level language architecture. See the
[video](https://www.youtube.com/watch?v=dlxMy_zrgAU) for a detailed
overview!

- [Redshirt](https://github.com/tomaka/redshirt)
- [Redox](https://gitlab.redox-os.org/redox-os/redox) :: is a Rust
  operating system with a microkernel-based design.
- [Urbit](https://github.com/urbit/urbit) :: A 'universal function'.
- [MetalOS](https://github.com/toddsharpe/MetalOS) :: A hobby project
  written by a single person.
- [InterimOS](https://github.com/mntmn/interim) :: Written to accompany
  mntmn's custom hardware.
- [CirnOS](https://github.com/mchlmmc/CirnOS) :: An operating system
  that transforms a Raspberry Pi into an Arduino. effectively.
- [Demikernel](https://github.com/demikernel/demikernel) :: interesting
  approach to architecture
- [CrysaLisp](https://github.com/vygr/ChrysaLisp) :: A next-generation
  Lisp machine.
- TempleOS (racist)
- [CollapseOS](https://collapseos.org/) :: An OS written entirely in the
  Forth programming language.
- Fuschia :: Google's up-and-coming unified desktop and mobile operating
  system. Presumably similar to Linux-SE (Android).
  <https://blog.quarkslab.com/playing-around-with-the-fuchsia-operating-system.html>
- Gentoo :: An operating system that prides itself on building
  everything from source. [Leaving
  Gentoo](https://ocharles.org.uk/posts/2012-07-09-leaving-gentoo.html)
  <https://www.paritybit.ca/blog/my-beginnings-with-gentoo>
  <https://timboudreau.com/blog/gentoo/read> gentoo seems like a great
  learning exp <https://wiki.gentoo.org/wiki/Raspberry_Pi#Hardware> help
  loading gentoo onto a pi {might be more helpful to put on qemu}
- [Qubes OS](https://www.qubes-os.org/intro/) :: 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](https://www.whonix.org/) :: An operating system designed to
  completely sandbox your activity inside of a virtual machine.
- Plan9 :: Defer to [Devine's notes on the
  subject](https://wiki.xxiivv.com/site/plan9.html).
  - Plan9 resources: <http://www.9gridchan.org/>
  - [Plan 9 System Calls](http://aiju.de/plan_9/plan9-syscalls)
  - [plan9 tools for unix operating systems](https://git.sr.ht/~ft/9pro)
- [Junos OS](https://en.m.wikipedia.org/wiki/Junos_OS)
- [Spectrum](https://spectrum-os.org/) :: 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

## Mobile

<https://news.ycombinator.com/item?id=23100713>

LineageOS  
The most popular alternative Android operating system, built off of
CyanogenMod. <https://wiki.lineageos.org/devices/starlte/install>
<https://www.reddit.com/r/degoogle/comments/gu2kk9/lineageos_vs_e_vs_alternatives/>

*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.

## Hobby

[I got my Gameboy emulator running in my OS! :
osdev](https://www.reddit.com/r/osdev/comments/hud8y2/i_got_my_gameboy_emulator_running_in_my_os/).
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!
