Grok (Knowledge Base)
''Grok'' is a neologism coined by American writer Robert A. Heinlein for his 1961 science fiction novel ''Stranger in a Strange Land''. While the ''Oxford English Dictionary'' summarizes the meaning of ''grok'' as "to understand intuitively or by empathy, to establish rapport with" and "to empathize or communicate sympathetically (with); also, to experience enjoyment", Heinlein's concept is far more nuanced, with critic Istvan Csicsery-Ronay Jr. observing that "the book's major theme can be seen as an extended definition of the term." The concept of ''grok'' garnered significant critical scrutiny in the years after the book's initial publication. The term and aspects of the underlying concept have become part of communities such as computer science. Descriptions of ''grok'' in ''Stranger in a Strange Land'' Critic David E. Wright Sr. points out that in the 1991 "uncut" edition of ''Stranger'', the word ''grok'' "was used first ''without any explicit definition'' on page 22" and ...

Neologism
A neologism Greek νÎο- ''néo''(="new") and λόγος /''lógos'' meaning "speech, utterance"] is a relatively recent or isolated term, word, or phrase that may be in the process of entering common use, but that has not been fully accepted into mainstream language. Neologisms are often driven by changes in culture and technology. In the process of language formation, neologisms are more mature than '' protologisms''. A word whose development stage is between that of the protologism (freshly coined) and neologism (new word) is a ''prelogism''. Popular examples of neologisms can be found in science, fiction (notably science fiction), films and television, branding, literature, jargon, cant, linguistics, the visual arts, and popular culture. Former examples include ''laser'' (1960) from Light Amplification by Stimulated Emission of Radiation; ''robot'' (1941) from Czech writer Karel ÄŒapek's play ''R.U.R. (Rossum's Universal Robots)''; and ''agitprop'' (1930) (a portmanteau of " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lisp (programming Language)
Lisp (historically LISP) is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation. Originally specified in 1960, Lisp is the second-oldest high-level programming language still in common use, after Fortran. Lisp has changed since its early days, and many dialects have existed over its history. Today, the best-known general-purpose Lisp dialects are Common Lisp, Scheme, Racket and Clojure. Lisp was originally created as a practical mathematical notation for computer programs, influenced by (though not originally derived from) the notation of Alonzo Church's lambda calculus. It quickly became a favored programming language for artificial intelligence (AI) research. As one of the earliest programming languages, Lisp pioneered many ideas in computer science, including tree data structures, automatic storage management, dynamic typing, conditionals, higher-order functions, recursion, the self-hosting compiler, and the read†...

Psychedelic Experience
A psychedelic experience (known colloquially as a trip) is a temporary altered state of consciousness induced by the consumption of a psychedelic substance (most commonly LSD, mescaline, psilocybin mushrooms, or DMT). For example, an acid trip is a psychedelic experience brought on by the use of LSD, while a mushroom trip is a psychedelic experience brought on by the use of psilocybin. Psychedelic experiences feature alterations in normal perception such as visual distortions and a subjective loss of self-identity, sometimes interpreted as mystical experiences. Psychedelic experiences lack predictability, as they can range from being highly pleasurable (known as a good trip) to frightening (known as a bad trip). The outcome of a psychedelic experience is heavily influenced by the person's mood, personality, expectations, and environment (also known as set and setting). Researchers have interpreted psychedelic experiences in light of a range of scientific theories, includin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Electric Kool-Aid Acid Test
''The Electric Kool-Aid Acid Test'' is a 1968 nonfiction book by Tom Wolfe. The book is a popular example of the New Journalism literary style. Wolfe presents a firsthand account of the experiences of Ken Kesey and his band of Merry Pranksters, who traveled across the US in a colorfully painted school bus, '' Furthur'', whose name was painted on the destination sign, indicating the general ethos of the Pranksters. Kesey and the Pranksters became famous for their use of psychedelic drugs such as LSD in order to achieve expansion of their consciousness. The book chronicles the Acid Tests (parties with LSD-laced Kool-Aid), encounters with notable figures of the time (Hells Angels, Grateful Dead, Allen Ginsberg) and describes Kesey's exile to Mexico and his arrests. Plot Wolfe chronicles the adventures of Ken Kesey and his group of followers. Throughout the work, Kesey is portrayed as desiring the creation of a new religion. Kesey forms a group of followers based on the allure of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tom Wolfe
Thomas Kennerly Wolfe Jr. (March 2, 1930 – May 14, 2018)Some sources say 1931; ''The New York Times'' and Reuters both initially reported 1931 in their obituaries before changing to 1930. See and was an American author and journalist widely known for his association with New Journalism, a style of news writing and journalism developed in the 1960s and 1970s that incorporated literary techniques. Wolfe began his career as a regional newspaper reporter in the 1950s, achieving national prominence in the 1960s following the publication of such best-selling books as ''The Electric Kool-Aid Acid Test'' (a highly experimental account of Ken Kesey and the Merry Pranksters) and two collections of articles and essays, '' Radical Chic & Mau-Mauing the Flak Catchers'' and ''The Kandy-Kolored Tangerine-Flake Streamline Baby''. In 1979, he published the influential book '' The Right Stuff'' about the Mercury Seven astronauts, which was made into a 1983 film of the same name directed by Ph ...

ElasticSearch
Elasticsearch is a search engine based on the Lucene library. It provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents. Elasticsearch is developed in Java and is dual-licensed under the source-available Server Side Public License and the Elastic license, while other parts fall under the proprietary ( ''source-available'') ''Elastic License''. Official clients are available in Java, .NET ( C#), PHP, Python, Ruby and many other languages. According to the DB-Engines ranking, Elasticsearch is the most popular enterprise search engine. History Shay Banon created the precursor to Elasticsearch, called Compass, in 2004. While thinking about the third version of Compass he realized that it would be necessary to rewrite big parts of Compass to "create a scalable search solution". So he created "a solution built from the ground up to be distributed" and used a common interface, JSON over HTTP, suitable for prog ...

Keystroke Logging
Keystroke logging, often referred to as keylogging or keyboard capturing, is the action of recording (logging) the keys struck on a keyboard, typically covertly, so that a person using the keyboard is unaware that their actions are being monitored. Data can then be retrieved by the person operating the logging program. A keystroke recorder or keylogger can be either software or hardware. While the programs themselves are legal, with many designed to allow employers to oversee the use of their computers, keyloggers are most often used for stealing passwords and other confidential information. Keylogging can also be used to study keystroke dynamics or human-computer interaction. Numerous keylogging methods exist, ranging from hardware and software-based approaches to acoustic cryptanalysis. Application of keylogger Software-based keyloggers A software-based keylogger is a computer program designed to record any input from the keyboard. Keyloggers are used in IT organizatio ...

Dennis Ritchie
Dennis MacAlistair Ritchie (September 9, 1941 – October 12, 2011) was an American computer scientist. He is most well-known for creating the C programming language and, with long-time colleague Ken Thompson, the Unix operating system and B programming language. Ritchie and Thompson were awarded the Turing Award from the ACM in 1983, the Hamming Medal from the IEEE in 1990 and the National Medal of Technology from President Bill Clinton in 1999. Ritchie was the head of Lucent Technologies System Software Research Department when he retired in 2007. He was the "R" in K&R C, and commonly known by his username dmr. Personal life and career Dennis Ritchie was born in Bronxville, New York. His father was Alistair E. Ritchie, a longtime Bell Labs scientist and co-author of ''The Design of Switching Circuits'' on switching circuit theory. As a child, Dennis moved with his family to Summit, New Jersey, where he graduated from Summit High School. He graduated from Harvard Universi ...

Brian Kernighan
Brian Wilson Kernighan (; born 1942) is a Canadian computer scientist. He worked at Bell Labs and contributed to the development of Unix alongside Unix creators Ken Thompson and Dennis Ritchie. Kernighan's name became widely known through co-authorship of the first book on the C programming language (''The C Programming Language'') with Dennis Ritchie. Kernighan affirmed that he had no part in the design of the C language ("it's entirely Dennis Ritchie's work"). He authored many Unix programs, including ditroff. Kernighan is coauthor of the AWK and AMPL programming languages. The "K" of K&R C and of AWK both stand for "Kernighan". In collaboration with Shen Lin he devised well-known heuristics for two NP-complete optimization problems: graph partitioning and the travelling salesman problem. In a display of authorial equity, the former is usually called the Kernighan–Lin algorithm, while the latter is known as the Lin–Kernighan heuristic. Kernighan has been a Professor of C ...

Cyberia (book)
''Cyberia'' is a book by Douglas Rushkoff, published in 1994. The book discusses many different ideas revolving around technology, drugs and subcultures. Rushkoff takes a Tom Wolfe '' Electric Kool-Aid Acid Test'' style (or ''roman à clef''), as he actively becomes a part of the people and culture that he is writing about. The book goes with Rushkoff as he discusses topics ranging from online culture, the concept of a global brain as put forth in Gaia theory, and Neoshamanism. In the preface of the 1994 edition, Rushkoff describes his book as "about a very special moment in our recent history – a moment when anything seemed possible. When an entire subculture – like a kid at a rave trying virtual reality for the first time – saw the wild potentials of marrying the latest computer technologies with the most intimately held dreams and the most ancient spiritual truths. It is a moment that predates America Online, twenty million Internet subscribers, ''Wired'' magazine, Bill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CPU Cache
A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations. Most CPUs have a hierarchy of multiple cache levels (L1, L2, often L3, and rarely even L4), with different instruction-specific and data-specific caches at level 1. The cache memory is typically implemented with static random-access memory (SRAM), in modern CPUs by far the largest part of them by chip area, but SRAM is not always used for all levels (of I- or D-cache), or even any level, sometimes some latter or all levels are implemented with eDRAM. Other types of caches exist (that are not counted towards the "cache size" of the most important caches mentioned above), such as the translation lookaside buffer (TLB) which is part of the memory management unit (MMU) w ...
