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

Real-time operating system From Wikipedia, the free encyclopedia Jump to: navigation search This article needs additional citations for verification Please help improve this article by adding reliable references . 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.

Spring (operating system) 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. Contents History Background Rationale Description ... edit History 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.

EROS (microkernel) 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 Contents Key concepts History Status See also ... edit Key concepts 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

30. 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

Flask: Flux Advanced Security Kernel 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: The Inevitability of Failure: The Flawed Assumption of Security in Modern Computing Environments ] explains the need for mandatory access controls in operating systems. The Flask Security Architecture: System Support for Diverse Security Policies ] describes the operating system security architecture through its prototype implementation in the Fluke research operating system. Implementing Mandatory Network Security in a Policy-flexible System ] describes a prototype of the Flask network security design in the Fluke implementation. Three reports describe the implementation of the Flask architecture in Fluke: Final Report Formal Security Policy Model Formal Top-Level Specification History of Flask 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 [

Flux Projects 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).

Jolix /joh'liks/ n.,adj. 386BSD Porting Unix to the 386: A Practical Approach Started open source UNIX. Appeared in part as a 17 article magazine series in 1991-1992. Documented the "how, what, why, who, when" of porting BSD to the 386. Done while BSD was becoming "open source". Links: Jolix - where to get things from Jolitz William Jolitz Lynne Jolitz 386BSD Design Videos Porting Unix to the 386: A Practical Approach "There are two ways of constructing a software design; one way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult." - C. A. R. Hoare In June of 1989 in Berlin, Germany much was about to change. What most don't know was what this had to do with the topic of "Open Source". William Jolitz was doing two week long seminars. The "wall" was a good symbol for the problem of open development with closed systems. What would happen if there was an open system, ... like ... perhaps ... bsd? Would it be popular?

Host addresses are collected and queried for their operating system using queso Queso is the Hispanic shortcut for "Que Sistema Operativo?" which translates into "which operating system?" For this OS count the RIPE Host Count was used to collect host addresses. Also host addresses of the .edu domain were used. (.edu is own host collection done with Eric Wassenaar's nameserver query tool host. ). All host names beginning with 'ftp.', 'news.' and 'www.' (case insensitive) were queried. Data collection was performed between 08. April 99 and 19. April 99 The current April count has processed hosts addresses.
