OpenStep – an object-oriented operating system that uses any modern operating system as its core. Mainly created by NeXT. NeXT Computer Inc, and Sun Microsystems Inc. teamed up in late 1993 to push a free object layer API based on the NeXTSTEP object system. This agreement evolved into the OpenStep specification which was published by NeXT in a first draft back in summer 1994.

There is a distinction between OpenStep, which is an API specification, and OPENSTEP (capitalized) which is a specific implementation of OpenStep developed by NeXT. Although it was originally created on a Unix-based Mach kernel (just like the NeXTSTEP core), OPENSTEP versions were also available on Solaris and Microsoft Windows NT. Therefore, OPENSTEP libraries (which were supplied with the OPENSTEP system) are actually a subset of the original OpenStep specification.

Inferno – an operating system designed for building distributed and networked systems on a wide variety of devices and platforms. Inferno was based on the experience gained with Plan 9 from Bell Labs, and currently being developed by Vita Nuova. Applications for this system are written in the Limbo language. The name of the system and some related programs (including Styx, Limbo) come from the Dante’s Divine Comedy.

Inferno can run as a user application on top of an existing operating system or as a stand alone operating system. Most of the popular operating systems and processor architectures are supported:
– Host Operating Systems
– Windows NT/2000/XP
– Irix
– Linux
– MacOS X
– FreeBSD
– Solaris
– Plan 9

Inferno applications are written in Limbo®, a modern, safe, modular, concurrent programming language with C-like syntax. It is more powerful than C but considerably easier to understand and debug than C++ or Java. It is easy to express the concurrency in the physical world directly in Limbo’s syntax. Any Inferno application will run identically on all Inferno platforms.

High level security is an important part of the Inferno system. By using one standard protocol for all network communication, security can be focused on one point and provided at a system level. Inferno offers full support for authenticated, encrypted connections using a certificate based user identification scheme and variety of algorithms.

Inferno 4 was released in 2005 as free software.

Founded in March 2000, Vita Nuova Holdings Ltd is an operating systems and application development company specializing in technologies for distributed applications on network devices and embedded systems.
