Space has been an interest for philosophers and scientists for much of human history, and hence it is difficult to provide an uncontroversial and clear definition outside of specific defined contexts. Disagreement exists on whether space itself can be measured or is part of the measuring system. (See Space in philosophy.) The term is also used somewhat differently in different fields of study. Many fields use an operational definition in which the units of measurement are defined.
Mathematical spaces
In mathematics, a space is a set, with some particular properties and usually some additional structure. It is not a formally defined concept as such, but a generic name for a number of similar concepts, most of which generalize some abstract properties of the physical concept of space.

Sometime in August, Microsoft plans to release Beta 2 of Internet Explorer 8. Yesterday, I spoke with Austin Wilson, Director of Windows Client Product Management at Microsoft, about some of the security-related changes due in this milestone, and got a preview of the changes announced today. Here are some details...

Meta Description: [ Bibliography of Single-Address-Space Operating Systems and related articles. This bibliography is a part of the Computer Science Bibliography Collection. ]
Mungi - Orthogonally persistent, capability-based secure SASOS using L4 2nd generation microkernel. Goals: Prove SASOSs can run on normal hardware, be as secure as normal OSs; can be as efficient as, and are faster than, normal OSs in some important uses; can be pure SASOSs with all data (even system data) in one address space and no other IPC mechanism is supported by OS. POSIX emulating. [Open Source, GPL]
Opal - Exploring a new OS structure, tuned to the needs of complex applications (eg, CAD/CAM) where a number of cooperating programs manipulate a large shared persistent database of objects.
ResearchIndex: Architectural Support for Single Address Space Operating Systems - From Proceedings of the International Conference on Architectural Support for Programming Languages and Operating Systems, Boston, USA, October 1992.
Meta Description: [ Recent microprocessor announcements show a trend toward wide address computers architectures that support bits of virtual address space. Such architectures facilitate fundamentally new operating system organizations that promote efficient data sharing and cooperation, both between complex applica... ]

Single Address Space Operating Systems - Short, annotated, alphabetically sorted list and links, part of larger system.
Single Address Space Operating Systems Archive, Dartmouth - Mail lists, projects, biographies (BibTeX, HTML long, HTML sans abstracts), a few links to other SASOS sites.
The Expected Lifetime of Single Address Space Operating Systems - Where stale pointers make it hard to re-use addresses, some have claimed that a 64-bit address space is so big that there is no need to ever re-use addresses. Results of extensive kernel-level tracing of department workstations.
Torsion - Multitasking SASOS with transparent data persistence: users and application programmers need not know or care that system memory is transient and must be written to disk to persist across reboots, all details done by OS, so once data is made, it exists until explicitly destroyed, like physical objects.
