  • floppybird

    Floppy Bird (OS)

  • Zeal-8-bit-OS

    An Operating System for Z80 computers, written in assembly

    Project mention: It's time to get the Posix elephant off our necks | | 2023-02-22

    Alternatives? While I somewhat agree with some points presented in the article, the POSIX model is beautiful in its simplicity. As a good demonstration, just take a look at Zeal 8-bit OS. It has a simplistic, Unix-inspired API [1], which is very elegant, especially considering the fact that the OS targets Z80 CPU with just 64 kB of RAM.


  • WorkOS

    The modern API for authentication & user identity. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • Cyjon

    A simple, clean code, multi-tasking kernel written in pure Assembly language for 64-bit processors from the AMD64 family.

  • zen

    Experimental operating system written in Zig

    Project mention: Zen: Experimental operating system written in Zig | | 2023-07-24
  • 64bit-os-tutorial

    This OS Tutorial expands on the fundamental concepts covered in cfenollosa/os-tutorial and covers entering long mode on the x86_64 architecture. It also uses clang rather than relying on an external crosscompiler. I plan on keeping it up to date, so feel free to submit an issue!

  • mintia

    Paging operating system for a custom computer architecture

    Project mention: Mintia: my paging operating system written in a custom language for a custom architecture | /r/osdev | 2023-07-08

    MINTIA is the flagship operating system for XR/station, and has itself been in the works for 2.5 years and counting. To meet some standard of "realism" for a late 80s workstation operating system, it has the following goals (in no particular order):

  • OS-Reference

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • AsmX

    🚀 AsmX - lang programming

    Project mention: AsmX – Lang Programming | | 2023-11-06
  • RSX280

    RSX-11M-like OS for the Z280 CPU.

    Project mention: Dec's OS-like RSX-11M for the Z280 CPU | /r/hypeurls | 2023-05-13
  • x86-kernel

    A hobby kernel developed from scratch using i8086 assembly

  • kernel

    A barebones x86 Kernel. (by mirimmad)
