Richard F. Rashid
Richard Farris Rashid is the founder of Microsoft Research, which he created in 1991. Between 1991 and 2013, as its chief research officer and director, he oversaw the worldwide operations for Microsoft Research which grew to encompass more than 850 researchers and a dozen labs around the world. Before joining Microsoft in 1991, Rashid had been the developer of the Mach kernel during his tenure as a professor of computer science at Carnegie Mellon University. The Mach multiprocessor operating system kernel developed by Rashid has had a lasting influence in the design of modern operating systems, including the design of Windows NT, and remains at the core of several operating systems such as NeXTSTEP, GNU Hurd, macOS, iOS, OSF/1, and Tru64 UNIX. Rashid's Mach kernel pioneered the concepts of microkernel architecture and its impact can be traced in today's computing landscape with hundreds of millions of people still using Mach based operating systems thirty years after i ...

Professional Developers Conference
Microsoft's Professional Developers Conference (PDC) was a series of conferences for software developers; the conference was held infrequently to coincide with beta releases of the Windows operating system, and showcased topics of interest to those developing hardware and software for the new version of Windows. In 2011, PDC was merged with Microsoft's web development conference MIX to form the Build Conference. Events * July 1992 - Moscone Center in San Francisco, California ** Known as Win32 Professional Developers Conference ** First demonstration of the Win32 API and first mention of "Chicago", which would eventually become Windows 95 ** Estimated attendance of over 5,000 developers ** Windows NT 3.1 Preliminary Release for Developers (build 297) was sent to all conference attendees * December 1993 - Anaheim Convention Center in Anaheim, California ** Windows "Chicago" ** Win32 and Object Linking and Embedding version 2 ** Estimated attendance of over 8,000 ** Cairo public ...

Microkernel
In computer science, a microkernel (often abbreviated as μ-kernel) is the near-minimum amount of software that can provide the mechanisms needed to implement an operating system (OS). These mechanisms include low-level address space management, thread management, and inter-process communication (IPC). If the hardware provides multiple rings or CPU modes, the microkernel may be the only software executing at the most privileged level, which is generally referred to as supervisor or kernel mode. Traditional operating system functions, such as device drivers, protocol stacks and file systems, are typically removed from the microkernel itself and are instead run in user space. In terms of the source code size, microkernels are often smaller than monolithic kernels. The MINIX 3 microkernel, for example, has only approximately 12,000 lines of code. History Microkernels trace their roots back to Danish computer pioneer Per Brinch Hansen and his tenure in Danish computer compan ...

Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of ...

Lebanon
Lebanon ( , ar, لُبْنَان, translit=lubnān, ), officially the Republic of Lebanon () or the Lebanese Republic, is a country in Western Asia. It is located between Syria to the north and east and Israel to the south, while Cyprus lies to its west across the Mediterranean Sea; its location at the crossroads of the Mediterranean Basin and the Arabian hinterland has contributed to its rich history and shaped a cultural identity of religious diversity. It is part of the Levant region of the Middle East. Lebanon is home to roughly six million people and covers an area of , making it the second smallest country in continental Asia. The official language of the state is Arabic, while French is also formally recognized; the Lebanese dialect of Arabic is used alongside Modern Standard Arabic throughout the country. The earliest evidence of civilization in Lebanon dates back over 7000 years, predating recorded history. Modern-day Lebanon was home to the Phoenicians, a m ...

Marjayoun
Marjayoun ( ar, مرج عيون: Lebanese pronunciation), also Marj 'Ayoun, Marjuyun or Marjeyoun (lit. "meadow of springs") and Jdeideh / Jdeida / Jdeidet Marjeyoun, is a Lebanese town and an administrative district, the Marjeyoun District, in the Nabatieh Governorate in Southern Lebanon. Geography Marjayoun is above sea level, standing on the west side of the Jordan Rift Valley just across from the ancient regional capital, Caesarea Philippi, which was located at the foot of Mount Hermon on the east side of the Rift Valley. It is not to be confused with the Banias Springs at Caesarea Philippi. Marjeyoun stands on a hill facing Mt Hermon to the east, the Crusader castle of Beafort, set above the Litani River and overlooking Mount Amel (Jabal Amel), to the west, the Mount Lebanon range with the Rihan and Niha peaks to the north, with the fertile Marjeyoun plains extending southward into the Galilee plains and the Golan Heights. History Crusader period On June 10, 1179, dur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
