Plan 9's designers were interested in similar goals as the microkernel world, but made rather different architecture and design choices to achieve them. Instead of asking the question "what do all operating systems want to do?", Plan 9 asked "what is Unix really trying to do?" The answers to these two questions are very different, and in the case of Plan 9 this included: represent everything as a file ...

Bell Telephone Laboratories Inc., also known as Bell Labs and AT&T Bell Laboratories, was the research and development arm of the US Bell System. It was the premier facility of its type, developing a range of revolutionary technologies including the transistor, Laser, and the UNIX operating system. There have been 6 Nobel Prizes awarded for work done at Bell Labs [1]. Bell Labs - History. In 1925, Walter Gifford, then president of AT&T, established Bell Telephone Laboratories Inc as a ...

The Alef programming language was designed by Phil Winterbottom of Bell Labs as part of the Plan 9 operating system. In a February 2000 slideshow, Rob Pike noted: "…although Alef was a fruitful language, it proved too difficult to maintain a variant language across multiple architectures, so we took what we learned from it and built the thread library for C." ...

In 1925, Walter Gifford, then president of AT&T, established Bell Telephone Laboratories Inc as a separate entity which took over work previously conducted by the research division of Western Electric's engineering department. Half of Bell Labs was owned by Western Electric, the other half being owned by AT&T. Discoveries and inventions at Bell Labs include: 1925: Facsimile (fax) transmission first demonstrated publicly 1927: Long-distance television transmission, of images of Herbert Hoover, from Washing ...

The work done by Bell Labs was broadly divided into three categories: research, systems engineering, and development. Research created the theoretical underpinnings for telecommunications. It covered subjects such as mathematics, physics, material sciences, behavioral sciences, and computer programming theory. Systems engineering concerned itself with conceiving the highly complex systems that make up the telecommunication networks. Development, by far the largest of Bell Labs' activities designed the specific systems -- both hardware and software -- needed to build the Bell Sy ...

Prior to the development of Plan 9, much of the ongoing research and development in operating systems had centered around several "hot" topics: multiprocessing and parallel computing, computer networking, and the idea of "subprograms" known as threads. Eventually it became clear that all operating systems were attempting to add these features at the same time. Development of these features was somewhat difficult, because if the feature under development were to have a bug, its placement inside the operating system's kernel would caus ...
