It supports 32/64 bit x86 assembly programming for smaller, faster and less resource hungry applications. Menuet has no roots within UNIX or the POSIX standards, nor is it based on any particular operating system. The design goal has been to remove the extra layers between different parts of an OS, which normally complicate programming and create bugs.
Minux3 is a new open-source operating system designed to be highly reliable, flexible, and secure. It is loosely based somewhat on previous versions of MINIX, but is fundamentally different in many key ways. MINIX 3 adds the new goal of being usable as a serious system on resource-limited and embedded computers and for applications requiring high reliability.

The GNU Hurd is the GNU project's replacement for the Unix kernel. The Hurd is a collection of servers that run on the Mach microkernel to implement file systems, network protocols, file access control, and other features that are implemented by the Unix kernel or similar kernels (such as Linux).
Plan 9 was born in the same lab where Unix began. Underneath, though, lies a new kind of system, organized around communication and naming rather than files and processes. In Plan 9, distributed computing is a central premise, not an evolutionary add-on. The system relies on a uniform protocol to refer to and communicate with objects, whether they be data or processes, and whether or not they live on the same machine or even similar machines. A single paradigm (writing to named places) unifies all kinds of control and interprocess signaling.
SharpOS is a community effort to write an operating system based on .NET technology, with a strong sense of security and manageability.
