Mark Weiser (composer)
Mark D. Weiser (July 23, 1952 – April 27, 1999) was a computer scientist and chief technology officer (CTO) at Xerox PARC. Weiser is widely considered to be the father of ubiquitous computing, a term he coined in 1988. Within Silicon Valley, Weiser was broadly viewed as a visionary and computer pioneer, and his ideas have influenced many of the world's leading computer scientists. Early life and education Weiser was born in Chicago, Illinois, to David and Audra Weiser. He grew up in Stony Brook, New York. He moved to Sarasota, Florida, to study philosophy at New College of Florida but dropped out in his second year when he ran out of money. He then moved to Ann Arbor, Michigan, where he found a job as a computer programmer. While working as a computer programmer he began taking computer science classes and excelled to the point that he was directly admitted into a master's program at the University of Michigan. He studied Computer and Communication Science at the Univ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Energy
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instructions Per Joule
In computing, performance per watt is a measure of the energy efficiency of a particular computer architecture or computer hardware. Literally, it measures the rate of computation that can be delivered by a computer for every watt of power consumed. This rate is typically measured by performance on the LINPACK benchmark when trying to compare between computing systems: an example using this is the Green500 list of supercomputers. Performance per watt has been suggested to be a more sustainable measure of computing than Moore’s Law. System designers building parallel computers, such as Google's hardware, pick CPUs based on their performance per watt of power, because the cost of powering the CPU outweighs the cost of the CPU itself. Spaceflight computers have hard limits on the maximum power available and also have hard requirements on minimum real-time performance. A ratio of processing speed to required electrical power is more useful than raw processing speed. D. J. Shirley; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instructions Per Second
Instructions per second (IPS) is a measure of a computer's processor speed. For complex instruction set computers (CISCs), different instructions take different amounts of time, so the value measured depends on the instruction mix; even for comparing processors in the same family the IPS measurement can be problematic. Many reported IPS values have represented "peak" execution rates on artificial instruction sequences with few branches and no cache contention, whereas realistic workloads typically lead to significantly lower IPS values. Memory hierarchy also greatly affects processor performance, an issue barely considered in IPS calculations. Because of these problems, synthetic benchmarks such as Dhrystone are now generally used to estimate computer performance in commonly used applications, and raw IPS has fallen into disuse. The term is commonly used in association with a metric prefix (k, M, G, T, P, or E) to form kilo instructions per second (kIPS), million instructions p ...

Calm Technology
Calm technology or calm design is a type of information technology where the interaction between the technology and its user is designed to occur in the user's periphery rather than constantly at the center of attention. Information from the technology smoothly shifts to the user's attention when needed but otherwise stays calmly in the user's periphery. Mark Weiser and John Seely Brown describe calm technology as "that which informs but doesn't demand our focus or attention." The use of calm technology is paired with ubiquitous computing as a way to minimize the perceptible invasiveness of computers in everyday life.Tugui, Alexandru (2004)"Calm Technologies In A Multimedia World" ACM Digital Library. Principles For a technology to be considered calm technology, there are three core principles it should adhere to: # The user's attention to the technology must reside mainly in the periphery. This means that either the technology can easily shift between the center of attention and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Severe Tire Damage (band)
Severe Tire Damage is an American rock and roll "garage" band from Palo Alto, California, United States. Innovation Severe Tire Damage was the first band to perform live on the Internet. On June 24, 1993, the band was playing a gig at Xerox PARC while elsewhere in the building, scientists were discussing new technology (the MBone) for broadcasting on the Internet using livestreaming (known as multicasting at the time). As proof of their technology, the band was broadcast and could be seen live in Australia and elsewhere. On Friday, November 18, 1994, the Rolling Stones decided to broadcast one of their concert tours on the Internet. Before their broadcast, Severe Tire Damage returned to the Internet, this time becoming the "opening act" for the Stones. Instead of an obscure Australian researcher, the entire world press was watching this time, and Severe Tire Damage was elevated from obscurity to Warholian fame. Newsweek magazine described Severe Tire Damage as being "a lesser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Music
Rock music is a broad genre of popular music that originated as " rock and roll" in the United States in the late 1940s and early 1950s, developing into a range of different styles in the mid-1960s and later, particularly in the United States and United Kingdom.W. E. Studwell and D. F. Lonergan, ''The Classic Rock and Roll Reader: Rock Music from its Beginnings to the mid-1970s'' (Abingdon: Routledge, 1999), p.xi It has its roots in 1940s and 1950s rock and roll, a style that drew directly from the blues and rhythm and blues genres of African-American music and from country music. Rock also drew strongly from a number of other genres such as electric blues and folk, and incorporated influences from jazz, classical, and other musical styles. For instrumentation, rock has centered on the electric guitar, usually as part of a rock group with electric bass guitar, drums, and one or more singers. Usually, rock is song-based music with a time signature using a verse–chorus form, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Experimental Rock
Experimental rock, also called avant-rock, is a subgenre of rock music that pushes the boundaries of common composition and performance technique or which experiments with the basic elements of the genre. Artists aim to liberate and innovate, with some of the genre's distinguishing characteristics being improvisation (music), improvisational performances, avant-garde influences, odd instrumentation, opaque lyrics (or instrumentals), unorthodox structures and rhythms, and an underlying rejection of commercial aspirations. From its inception, rock music was experimental, but it was not until the late 1960s that rock artists began creating extended and complex compositions through advancements in multitrack recording. In 1967, the genre was as commercially viable as Popular music, pop music, but by 1970, most of its leading players had incapacitated themselves in some form. In Germany, the krautrock subgenre merged elements of improvisation and psychedelic rock with electronic music, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
