NewOS – an alternative, modular and open-source operating system, based on a micro kernel written by a former Be Inc. employee Travis Geiselbrecht. It is largely implemented in C/C++, with a small amount of assembly.

The system is mostly a kernel with a minimal amount of user space libraries and applications so it isn’t interesting from an end-user point of view – there is no gui, simple commands on a command line.

NewOS provides a flexible framework to build other systems out of, cross-platform portability, provides a clean implementation that can be used as a learning tool for others and gives an educational opportunity for developers.

Haiku OS (previously: OpenBeOS), which is still under active development is based on NewOS.

Michael Noisternig took over the NewOS source code, and has implemented new ideas creating a fork named NewOS-Notion (?).
