Hydra (operating system)
HYDRA is an early (now discontinued) capability-based, object-oriented, microkernel designed to support a wide range of possible operating systems to run on top of it.[1] HYDRA was created as part of the C.mmp project at Carnegie-Mellon University in 1971.[2]
The name is based on the ancient Greek mythological creature the hydra.
HYDRA was designed to be modular and secure, and intended to be flexible enough for easy experimentation.[3] The system was implemented in the programming language BLISS.[4]
