IBM 704
The IBM 704 is a large digital mainframe computer introduced by IBM in 1954. It was the first mass-produced computer with hardware for floating-point arithmetic. The IBM 704 ''Manual of operation'' states: The type 704 Electronic Data-Processing Machine is a large-scale, high-speed electronic calculator controlled by an internally stored program of the single address type. The 704 at that time was thus regarded as "pretty much the only computer that could handle complex math". The 704 was a significant improvement over the earlier IBM 701 in terms of architecture and implementation. Like the 701, the 704 uses vacuum-tube logic circuitry, but increased the instruction size from 18-bit to 36-bit, the same as the memory's word size. Changes from the 701 include the use of magnetic-core memory instead of Williams tubes, floating-point arithmetic instructions, 15-bit addressing and the addition of three index registers. To support these new features, the instructions we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Symbolic Assembly Program
The Symbolic Assembly Program (SAP) is an assembler program for the IBM 704 computer. It was written by Roy Nutt at United Aircraft Corporation, and was distributed by the SHARE user's group beginning in 1956 as the ''Share Assembly Program''. SAP succeeded an earlier program called NYAP1 (New York Assembly Program 1), which it closely resembled, and became the standard assembler for 704 users. It "set the external form of an assembly language that was to be a model for all its successors and which persists almost unchanged to the present day." DARSIMCO, short for Dartmouth Simplified Code, was a simple programming language written by John Kemeny (who later co-developed BASIC) in 1956 that expanded simple mathematical operations into a program that would then be assembled by SAP. Description SAP is a two-pass assembler. It is capable of running on a 704 with a minimum of 4 K 36-bit words of core storage. This configuration allows up to 1097 entries in the symbol table.

Blackjack
Blackjack (formerly Black Jack and Vingt-Un) is a casino banking game. The most widely played casino banking game in the world, it uses decks of 52 cards and descends from a global family of casino banking games known as Twenty-One. This family of card games also includes the British game of Pontoon, the European game, Vingt-et-Un and the Russian game Ochko. Blackjack players do not compete against each other. The game is a comparing card game where each player competes against the dealer. History Blackjack's immediate precursor was the English version of '' twenty-one'' called ''Vingt-Un'', a game of unknown (but likely Spanish) provenance. The first written reference is found in a book by the Spanish author Miguel de Cervantes. Cervantes was a gambler, and the protagonists of his " Rinconete y Cortadillo", from ''Novelas Ejemplares'', are card cheats in Seville. They are proficient at cheating at ''veintiuna'' (Spanish for "twenty-one") and state that the object of the gam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward O
Edward is an English given name A given name (also known as a forename or first name) is the part of a personal name quoted in that identifies a person, potentially with a middle name as well, and differentiates that person from the other members of a group (typically a fa .... It is derived from the Anglo-Saxon name ''Ēadweard'', composed of the elements '' ēad'' "wealth, fortune; prosperous" and ''wikt:weard#Old English, weard'' "guardian, protector”. History The name Edward was very popular in Anglo-Saxon England, but the rule of the House of Normandy, Norman and House of Plantagenet, Plantagenet dynasties had effectively ended its use amongst the upper classes. The popularity of the name was revived when Henry III of England, Henry III named his firstborn son, the future Edward I of England, Edward I, as part of his efforts to promote a cult around Edward the Confessor, for whom Henry had a deep admiration.

HAL 9000
HAL 9000 is a fictional artificial intelligence character and the main antagonist in Arthur C. Clarke's ''Space Odyssey'' series. First appearing in the 1968 film '' 2001: A Space Odyssey'', HAL ( Heuristically programmed ALgorithmic computer) is a sentient artificial general intelligence computer that controls the systems of the '' Discovery One'' spacecraft and interacts with the ship's astronaut crew. While part of HAL's hardware is shown toward the end of the film, he is mostly depicted as a camera lens containing a red or yellow dot, with such units located throughout the ship. HAL 9000 is voiced by Douglas Rain in the two feature film adaptations of the ''Space Odyssey'' series. HAL speaks in a soft, calm voice and a conversational manner, in contrast to the crewmen, David Bowman and Frank Poole. In the film, HAL became operational on 12 January 1992 at the HAL Laboratories in Urbana, Illinois as production number 3. The activation year was 1991 in earlier screenpl ...

A Space Odyssey (film)
''2001: A Space Odyssey'' is a 1968 science fiction novel written by Arthur C. Clarke and the 1968 film directed by Stanley Kubrick. It is a part of Clarke's ''Space Odyssey'' series, the first of four novels and two films. Both the novel and the film are partially based on Clarke's 1948 short story " The Sentinel", an entry in a BBC short story competition, and "Encounter in the Dawn", published in 1953 in the magazine ''Amazing Stories''. Resources After deciding on Clarke's 1948 short story "The Sentinel" as the starting point, and with the themes of man's relationship with the universe in mind, Clarke sold Kubrick five more of his stories to use as background materials for the film. These included "Breaking Strain", "Out of the Cradle, Endlessly Orbiting...", "Who's There?", "Into the Comet", and "Before Eden". Additionally, important elements from two more Clarke stories, "Encounter in the Dawn" and (to a somewhat lesser extent) "Rescue Party", made their way into ...

Speech Synthesis
Speech synthesis is the artificial production of human speech. A computer system used for this purpose is called a speech synthesizer, and can be implemented in software or hardware products. A text-to-speech (TTS) system converts normal language text into speech; other systems render symbolic linguistic representations like phonetic transcriptions into speech. The reverse process is speech recognition. Synthesized speech can be created by concatenating pieces of recorded speech that are stored in a database. Systems differ in the size of the stored speech units; a system that stores phones or diphones provides the largest output range, but may lack clarity. For specific usage domains, the storage of entire words or sentences allows for high-quality output. Alternatively, a synthesizer can incorporate a model of the vocal tract and other human voice characteristics to create a completely "synthetic" voice output. The quality of a speech synthesizer is judged by its similarity to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur C
Arthur is a common male given name of Brythonic origin. Its popularity derives from it being the name of the legendary hero King Arthur. The etymology is disputed. It may derive from the Celtic ''Artos'' meaning “Bear”. Another theory, more widely believed, is that the name is derived from the Roman clan '' Artorius'' who lived in Roman Britain for centuries. A common spelling variant used in many Slavic, Romance, and Germanic languages is Artur. In Spanish and Italian it is Arturo. Etymology The earliest datable attestation of the name Arthur is in the early 9th century Welsh-Latin text ''Historia Brittonum'', where it refers to a circa 5th to 6th-century Briton general who fought against the invading Saxons, and who later gave rise to the famous King Arthur of medieval legend and literature. A possible earlier mention of the same man is to be found in the epic Welsh poem ''Y Gododdin'' by Aneirin, which some scholars assign to the late 6th century, though this is still a ...

Daisy Bell
"Daisy Bell (Bicycle Built for Two)" is a song written in 1892 by British songwriter Harry Dacre with the well-known chorus "Daisy, Daisy / Give me your answer, do. / I'm half crazy / all for the love of you", ending with the words "a bicycle built for two". The song is said to have been inspired by Daisy Greville, Countess of Warwick, one of the many mistresses of King Edward VII. It is the earliest song sung using computer speech synthesis by the IBM 704 in 1961, a feat that was referenced in the film '' 2001: A Space Odyssey'' (1968). Also referenced in the movie ''Robots'' (2005) by Blue Sky Studios. History "Daisy Bell" was composed by Harry Dacre in 1892. As David Ewen writes in ''American Popular Songs'': The song was originally recorded and released by Dan W. Quinn in 1893. In technology and culture Computing and technology * In 1961, an IBM 704 at Bell Labs was programmed to sing "Daisy Bell" in the earliest demonstration of computer speech synthesis. This ...

Vocoder
A vocoder (, a portmanteau of ''voice'' and ''encoder'') is a category of speech coding that analyzes and synthesizes the human voice signal for audio data compression, multiplexing, voice encryption or voice transformation. The vocoder was invented in 1938 by Homer Dudley at Bell Labs as a means of synthesizing human speech. This work was developed into the channel vocoder which was used as a voice codec for telecommunications for speech coding to conserve bandwidth in transmission. By encrypting the control signals, voice transmission can be secured against interception. Its primary use in this fashion is for secure radio communication. The advantage of this method of encryption is that none of the original signal is sent, only envelopes of the bandpass filters. The receiving unit needs to be set up in the same filter configuration to re-synthesize a version of the original signal spectrum. The vocoder has also been used extensively as an electronic musical instrument. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Larry Kelly, Jr
John Larry Kelly Jr. (December 26, 1923 – March 18, 1965), was an American scientist who worked at Bell Labs. From a "system he'd developed to analyze information transmitted over networks," from Claude Shannon's earlier work on information theory, he is best known for his 1956 work in creating the ''Kelly criterion'' formula. With notable volatility in its sequence of outcomes, the Kelly criterion can be used to estimate what proportion of wealth to risk in a sequence of positive expected value bets to maximize the rate of return."The Man Who Solved the Market", Gregory Zuckerman, 2019 As a substantial warning, the outcome for the Kelly criterion's recommendation on bet-size "relies heavily on the accuracy" of the statistical probabilities given to a gamble's positive expectations. Early life He was born in Corsicana, Texas. He spent four years in the US Navy as a pilot during World War II before entering the University of Texas at Austin. He graduated with a PhD in physics ...
