Announcing Minoca OS: An Open‑Source, Modular Operating System for Small Devices

We are pleased to announce that Minoca OS has been open‑sourced under the GNU GPLv3 license, and the source code is available at https://github.com/minoca/os . The project seeks to build a community of users and developers to help improve the system.

Minoca OS is a general‑purpose operating system written entirely from scratch, designed for devices that need to conserve power, memory, and storage. Its goals are simplicity, maintainability, modularity, and compatibility with existing software, effectively providing a full‑featured OS for small devices.

On the application side Minoca includes a package manager (opkg) with an expanding repository that already offers Python, Ruby, Git, Lua, and Node. Under the hood, it features a robust driver model that sits between device drivers and the kernel, allowing drivers to be written in a forward‑compatible way so kernel components can be upgraded without recompiling all drivers.

The OS was created by two developers, Evan and Chris, who recognized that most mainstream operating systems have not been rewritten in over 25 years, accumulating legacy baggage while hardware has dramatically changed. They see an opportunity to redesign kernel‑driver interfaces, improve power management, availability, and resource isolation, and deliver OS functionality comparable to modern systems with less code and fewer pain points.

The project’s biggest current challenge is limited adoption. The team asks the community to identify missing packages, report crashes, and suggest improvements to make the system more usable. They also welcome contributions such as driver development, feature additions, package ports, bug fixes, and design discussions.

Contact information is provided for general inquiries ([email protected]), patches and technical discussions ([email protected]), and security issues ([email protected]).

A lively discussion follows about Minoca’s POSIX compatibility and whether its network stack should follow Plan 9’s model. Various community members comment on the merits of POSIX as a gateway to a large software ecosystem, the potential of Plan 9‑style networking, and the overall code quality of Minoca, citing examples such as iobase.c .
