PSOS (real-time Operating System)
pSOS (Portable Software On Silicon) is a real-time operating system (RTOS), created in about 1982 by Alfred Chao, and developed and marketed for the first part of its life by his company Software Components Group (SCG). In the 1980s, pSOS rapidly became the RTOS of choice for all embedded systems based on the Motorola 68000 series family architecture, because it was written in 68000 assembly language and was highly optimised from the start. It was also modularised, with early support for OS-aware debugging, plug-in device drivers, Internet protocol suite (TCP/IP) stacks, language libraries, and disk subsystems. Later came source code level debugging, multiprocessing support, and further computer networking extensions. In about 1991, Software Components Group was acquired by Integrated Systems Inc. (ISI) which further developed pSOS, then renamed as pSOS+, for other microprocessor families, by rewriting most of it in the programming language C. Attention was also paid ...

Provably Secure Operating System
Peter Gabriel Neumann (born 1932) is a computer-science researcher who worked on the Multics operating system in the 1960s. He edits the RISKS Digest columns for ACM ''Software Engineering Notes'' and ''Communications of the ACM''. He founded ACM SIGSOFT and is a Fellow of the ACM, IEEE, and AAAS. Early life and education Neumann holds three degrees from Harvard University: a A.B. in Mathematics, 1954; and a S.M. (1955) and Ph.D. (1961) in Applied Mathematics and Science. He held a Fulbright scholarship in Germany from 1958–1960. While a student at Harvard, he had a two-hour breakfast with Albert Einstein, on 8 November 1952, discussing simplicity in design. Career Neumann worked at Bell Labs from 1960 to 1970. He has worked at SRI International in Menlo Park, California since 1971. Before the RISKS mailing list, Neumann was known for the Provably Secure Operating System (PSOS). Neumann worked with Dorothy E. Denning in the 1980s to develop a computer intrusion detecti ...

Project Support Open Source
A project is any undertaking, carried out individually or collaboratively and possibly involving research or design, that is carefully planned to achieve a particular goal. An alternative view sees a project managerially as a sequence of events: a "set of interrelated tasks to be executed over a fixed period and within certain cost and other limitations". A project may be a temporary (rather than a permanent) social system ( work system), possibly staffed by teams (within or across organizations) to accomplish particular tasks under time constraints. A project may form a part of wider programme management or function as an ''ad hoc'' system. Note that open-source software "projects" or artists' musical "projects" (for example) may lack defined team-membership, precise planning and/or time-limited durations. Overview The word ''project'' comes from the Latin word ''projectum'' from the Latin verb ''proicere'', "before an action," which in turn comes from ''pro-'', which d ...

Protective Services Officers
A police community support officer (PCSO; cy, swyddog cymorth cymunedol yr heddlu, SCCH), or as written in legislation community support officer (CSO; cy, swyddog cymorth cymunedol, SCC) is a uniformed member of police staff in England and Wales, a role created by Section 38(2) of the Police Reform Act 2002, which was given Royal Assent by Queen Elizabeth II on 24 July 2002. They are non-warranted but provided with a variety of police powers and the power of a constable in various instances by the forty-three territorial police forces in England and Wales and the British Transport Police (which is the only specialist police service to employ PCSOs). PCSOs were introduced in September 2002 and first recruited by the Metropolitan Police. Proposals for PCSOs in Northern Ireland were prevented by a budget shortfall in the Police Service of Northern Ireland, as well as fears that the introduction of uniformed and unarmed PCSOs in Northern Ireland (PSNI constables all carry firear ...

Police Service Of Scotland
Police Scotland ( gd, Poileas Alba), officially the Police Service of Scotland (), is the national police force of Scotland. It was formed in 2013, through the merging of eight regional police forces in Scotland, as well as the specialist services of the Scottish Police Services Authority, including the Scottish Crime and Drug Enforcement Agency. Although not formally absorbing it, the merger also resulted in the winding up of the Association of Chief Police Officers in Scotland. Police Scotland is the second-largest police force in the United Kingdom (after the Metropolitan Police Service) in terms of officer numbers, and by far the largest territorial police force in terms of its geographic area of responsibility. The chief constable is answerable to the Scottish Police Authority, and the force is inspected by His Majesty's Inspectorate of Constabulary in Scotland. Scotland is also policed by the Ministry of Defence Police, British Transport Police, and the Civil Nuclear Co ...
