The Glaux operating system is free software, written in a subset of C by Alexandros Alexandrou (Αλέξανδρος Αλεξάνδρου). It aims to provide security, reliability, speed and minimised memory consuption. It should also not depend on third party programs for building, as the relevant utilities are also being written from scratch, in order to have better control over their quality.
The final operating system is still being designed, but you can help by contacting the main developer and submitting ideas and/or code.
For those interested at the previous attempts, you can look at them at gitlab.com. Please note however that these codebases do not reflect the current goals of the Glaux project.
You can contact the main developer by emailing to the firstname.lastname@example.org address. You can also join the #glaux-os and #glaux-toolchain channels at the freenode.net IRC network. Please note however that these channels are usually inactive.
