Extractions: George Bernard Shaw What is MkLinux? MkLinux is a project begun by the OSF Research Institute (now Silicomp RI) and Apple Computer to port Linux, a freely distributed UNIX-like operating system, to a variety of Power Macintosh platforms running on top of OSF Research Institute's implementation of the Mach microkernel. Beginning in the summer of 1998, development work on MkLinux transitioned from Apple and OSF to a community-led effort. A more-complete-but-still-brief history can be found on the

Unsourced material may be challenged and removed (August 2010) A real-time operating system RTOS ) is an operating system (OS) intended to serve real-time application requests. A key characteristic of an RTOS is the level of its consistency concerning the amount of time it takes to accept and complete an application's task ; the variability is jitter . A hard real-time operating system has less jitter than a soft real-time operating system. The chief design goal is not high throughput , but rather a guarantee of a soft or hard performance category. An RTOS that can usually or generally meet a deadline is a soft real-time OS, but if it can meet a deadline deterministically it is a hard real-time OS. citation needed A real-time OS has an advanced algorithm for scheduling . Scheduler flexibility enables a wider, computer-system orchestration of process priorities, but a real-time OS is more frequently dedicated to a narrow set of applications. Key factors in a real-time OS are minimal interrupt latency and minimal thread switching latency , but a real-time OS is valued more for how quickly or how predictably it can respond than for the amount of work it can perform in a given period of time.
Extractions: From Wikipedia, the free encyclopedia Jump to: navigation search Spring was an experimental microkernel -based object oriented operating system developed at Sun Microsystems in the early 1990s. Using technology substantially similar to concepts developed in the Mach kernel , Spring concentrated on providing a richer programming environment supporting multiple inheritance and other features. Spring was also more cleanly separated from the operating systems it would host, divorcing it from its Unix roots and even allowing several OSes to be run at the same time. Development faded out in the mid-1990s, but several ideas and some code from the project was later re-used in the Java programming language libraries and the Solaris operating system. Spring Research Distribution 1.0 CD cover Spring started in a roundabout fashion in 1987, as part of Sun and 's collaboration to create a merged UNIX , both companies decided it was also a good opportunity to "reimplement UNIX in an object-oriented fashion". However, after only a few meetings, this part of the project died.
Extractions: From Wikipedia, the free encyclopedia   (Redirected from Extremely Reliable Operating System Jump to: navigation search EROS The Extremely Reliable Operating System ) is an operating system developed by The EROS Group, LLC., the Johns Hopkins University , and the University of Pennsylvania . Features include automatic data and process persistence , some preliminary real-time support, and capability-based security . EROS is purely a research operating system, and was never deployed in real world use. As of 2005 [update] , development has stopped in favor of two successor systems, CapROS and Coyotos The overriding goal of the EROS system (and its relatives) is to provide strong support at the operating system level for the efficient restructuring of critical applications into small communicating components. Each component can communicate with the others only through protected interfaces, and is isolated from the rest of the system. A "protected interface", in this context, is one that is enforced by the lowest level part of the operating system (the kernel ). The kernel is the only portion of the system that can move information from one process to another. It also has complete control of the machine and (if properly constructed) cannot be bypassed. In EROS, the kernel-provided mechanism by which one component names and invokes the services of another is

Flask: Flux Advanced Security Kernel The Flask operating system security architecture provides flexible support for security policies. The architecture has previously been implemented in two research operating systems, Mach and Fluke, and is now being implemented in the Linux kernel. http://www.cs.utah.edu/flux/fluke/html/flask.html
Extractions: Flask is an operating system security architecture that provides flexible support for security policies. The architecture was prototyped in the Fluke research operating system. Several of the Flask interfaces and components were then ported from the Fluke prototype to the OSKit . The Flask architecture is now being implemented in the Linux operating system ( Security-Enhanced Linux ) to transfer the technology to a larger developer and user community. The following papers are useful in understanding Flask and its implementation in Fluke: Three reports describe the implementation of the Flask architecture in Fluke: In 1992 and 1993, researchers at the National Security Agency (NSA) and Secure Computing Corporation (SCC) worked on the design and implementation of Distributed Trusted Mach [

Extractions: The OSKit is a framework and a set of 34 component libraries For language researchers and enthusiasts, the OSKit lets them concentrate on the real issues raised by using advanced languages inside operating systems, such as Java, Lisp, Scheme, or ML- instead of spending six months or years groveling inside ugly code and hardware. With the recent addition of extensive multithreading and sophisticated scheduling support, the OSKit also provides a nmodular platform for embedded applications, as well as a novel component-based approach to constructing entire operating systems. Although the OSKit contains substantial machine-independent code, it currently only contains machine-dependent code for the Intel x86 and Digital DNARD (StrongArm SA-110 CPU).
