Louvre
–
The Louvre or the Louvre Museum is the worlds largest museum and a historic monument in Paris, France. A central landmark of the city, it is located on the Right Bank of the Seine in the citys 1st arrondissement, approximately 38,000 objects from prehistory to the 21st century are exhibited over an area of 72,735 square metres. The Louvre is the second most visited museum after the Palace Museum in China. The museum is housed in the Louvre Palace, originally built as a fortress in the late 12th century under Philip II, remnants of the fortress are visible in the basement of the museum. Due to the expansion of the city, the fortress eventually lost its defensive function and. The building was extended many times to form the present Louvre Palace, in 1692, the building was occupied by the Académie des Inscriptions et Belles Lettres and the Académie Royale de Peinture et de Sculpture, which in 1699 held the first of a series of salons. The Académie remained at the Louvre for 100 years, during the French Revolution, the National Assembly decreed that the Louvre should be used as a museum to display the nations masterpieces. The museum opened on 10 August 1793 with an exhibition of 537 paintings, because of structural problems with the building, the museum was closed in 1796 until 1801. The collection was increased under Napoleon and the museum renamed Musée Napoléon, the collection was further increased during the reigns of Louis XVIII and Charles X, and during the Second French Empire the museum gained 20,000 pieces. Holdings have grown steadily through donations and bequests since the Third Republic, whether this was the first building on that spot is not known, it is possible that Philip modified an existing tower. According to the authoritative Grand Larousse encyclopédique, the name derives from an association with wolf hunting den, in the 7th century, St. Fare, an abbess in Meaux, left part of her Villa called Luvra situated in the region of Paris to a monastery. This territory probably did not correspond exactly to the modern site, the Louvre Palace was altered frequently throughout the Middle Ages. In the 14th century, Charles V converted the building into a residence and in 1546, Francis acquired what would become the nucleus of the Louvres holdings, his acquisitions including Leonardo da Vincis Mona Lisa. After Louis XIV chose Versailles as his residence in 1682, constructions slowed, however, on 14 October 1750, Louis XV agreed and sanctioned a display of 96 pieces from the royal collection, mounted in the Galerie royale de peinture of the Luxembourg Palace. Under Louis XVI, the museum idea became policy. The comte dAngiviller broadened the collection and in 1776 proposed conversion of the Grande Galerie of the Louvre – which contained maps – into the French Museum, many proposals were offered for the Louvres renovation into a museum, however, none was agreed on. Hence the museum remained incomplete until the French Revolution, during the French Revolution the Louvre was transformed into a public museum. In May 1791, the Assembly declared that the Louvre would be a place for bringing together monuments of all the sciences, on 10 August 1792, Louis XVI was imprisoned and the royal collection in the Louvre became national property

Ford Model T
–
The Ford Model T is an automobile that was produced by Ford Motor Company from October 1,1908, to May 26,1927. The Ford Model T was named the most influential car of the 20th century in the 1999 Car of the Century competition, ahead of the BMC Mini, Citroën DS, and Volkswagen Type 1. With 16.5 million sold it stands eighth on the top ten list of most sold cars of all time as of 2012, although automobiles had already existed for decades, they were still mostly scarce and expensive at the Model Ts introduction in 1908. Positioned as reliable, easily maintained mass market transportation, it was a runaway success, in a matter of days after the release,15,000 orders were placed. The first production Model T was produced on August 12,1908 and left the factory on September 27,1908, at the Ford Piquette Avenue Plant in Detroit, Michigan. On May 26,1927, Henry Ford watched the 15 millionth Model T Ford roll off the line at his factory in Highland Park. There were several cars produced or prototyped by Henry Ford from the founding of the company in 1903 until the Model T was introduced, although he started with the Model A, there were not 19 production models, some were only prototypes. The production model immediately before the Model T was the Model S, a version of the companys largest success to that point. The follow-up was the Ford Model A, the company publicity said this was because the new car was such a departure from the old that Henry wanted to start all over again with the letter A. The Model T was Fords first automobile mass-produced on moving assembly lines with completely interchangeable parts, Henry Ford said of the vehicle, I will build a car for the great multitude. It will be enough for the family, but small enough for the individual to run. It will be constructed of the best materials, by the best men to be hired, after the simplest designs that modern engineering can devise. But it will be so low in price that no man making a good salary will be unable to own one –, although credit for the development of the assembly line belongs to Ransom E. The Model T was designed by Childe Harold Wills, and Hungarian immigrants Joseph A. Galamb, Henry Love, C. J. Smith, Gus Degner and Peter E. Martin were also part of the team. Production of the Model T began in the quarter of 1908. Collectors today sometimes classify Model Ts by build years and refer to these as model years and this is a retroactive classification scheme, the concept of model years as we conceive it today did not exist at the time. The nominal model designation was Model T, although design revisions did occur during the two decades of production. The Model T had a front-mounted 177-cubic-inch inline four-cylinder engine, producing 20 hp, according to Ford Motor Company, the Model T had fuel economy on the order of 13–21 mpg‑US

Computer science
–
Computer science is the study of the theory, experimentation, and engineering that form the basis for the design and use of computers. An alternate, more succinct definition of science is the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems and its fields can be divided into a variety of theoretical and practical disciplines. Some fields, such as computational complexity theory, are highly abstract, other fields still focus on challenges in implementing computation. Human–computer interaction considers the challenges in making computers and computations useful, usable, the earliest foundations of what would become computer science predate the invention of the modern digital computer. Machines for calculating fixed numerical tasks such as the abacus have existed since antiquity, further, algorithms for performing computations have existed since antiquity, even before the development of sophisticated computing equipment. Wilhelm Schickard designed and constructed the first working mechanical calculator in 1623, in 1673, Gottfried Leibniz demonstrated a digital mechanical calculator, called the Stepped Reckoner. He may be considered the first computer scientist and information theorist, for, among other reasons and he started developing this machine in 1834, and in less than two years, he had sketched out many of the salient features of the modern computer. A crucial step was the adoption of a card system derived from the Jacquard loom making it infinitely programmable. Around 1885, Herman Hollerith invented the tabulator, which used punched cards to process statistical information, when the machine was finished, some hailed it as Babbages dream come true. During the 1940s, as new and more powerful computing machines were developed, as it became clear that computers could be used for more than just mathematical calculations, the field of computer science broadened to study computation in general. Computer science began to be established as an academic discipline in the 1950s. The worlds first computer science program, the Cambridge Diploma in Computer Science. The first computer science program in the United States was formed at Purdue University in 1962. Since practical computers became available, many applications of computing have become distinct areas of study in their own rights and it is the now well-known IBM brand that formed part of the computer science revolution during this time. IBM released the IBM704 and later the IBM709 computers, still, working with the IBM was frustrating if you had misplaced as much as one letter in one instruction, the program would crash, and you would have to start the whole process over again. During the late 1950s, the science discipline was very much in its developmental stages. Time has seen significant improvements in the usability and effectiveness of computing technology, modern society has seen a significant shift in the users of computer technology, from usage only by experts and professionals, to a near-ubiquitous user base

Serial code
–
A serial code is a unique identifier assigned incrementally or sequentially to an item. It is also called a number, although it may be a character string that includes letters and other typographical symbols. Serial numbers identify otherwise identical individual units with many, obvious uses, Serial numbers are a deterrent against theft and counterfeit products, as they can be recorded, and stolen or otherwise irregular goods can be identified. Banknotes and other documents of value bear serial numbers to assist in preventing counterfeiting and tracing stolen ones. They are valuable in quality control, as once a defect is found in the production of a batch of product. Serial numbers may be used to identify individual physical or intangible objects, the purpose and application is different. A software serial number, otherwise called product key, is not embedded in the software. The software will function if a potential user enters a valid product code. The vast majority of codes are rejected by the software. If an unauthorised user is found to be using the software, the term serial number is sometimes used for codes which do not identify a single instance of something. It takes its name from the library use of the word serial to mean a periodical. Certificates and certificate authorities are necessary for use of cryptography. These depend on applying mathematically rigorous serial numbers and serial number arithmetic, the term serial number is also used in military formations as an alternative to the expression service number. Because of this, the number is sometimes called a tail number. LZ548/G—the prototype de Havilland Vampire jet fighter, or ML926/G—a de Havilland Mosquito XVI experimentally fitted with H2S radar, the serial number follows the aircraft throughout its period of service. In 2009 the U. S. FDA published draft guidance for the industry to use serial numbers on prescription drug packages. This measure will enhance the traceability of drugs and help to prevent counterfeiting, Serial numbers are often used in network protocols. However, most sequence numbers in computer protocols are limited to a number of bits

German tank problem
–
In the statistical theory of estimation, the German tank problem involves estimating the maximum of a discrete uniform distribution from sampling without replacement. It is named from its application in World War II to the estimation of the number of German tanks and this analysis shows the approach that was used and illustrates the difference between frequentist inference and Bayesian inference. Suppose k =4 tanks with serial numbers 19,40,42 and 60 are captured, the maximal observed serial number, m =60. The unknown total number of tanks is called N.5 ±50.22 and this distribution has positive skewness, related to the fact that there are at least 60 tanks. In many cases, statistical analysis substantially improved on conventional intelligence, in some cases, conventional intelligence was used in conjunction with statistical methods, as was the case in estimation of Panther tank production just prior to D-Day. The US Army was confident that the Sherman tank would continue to perform well, as it had versus the Panzer III and Panzer IV tanks in North Africa, shortly before D-Day, rumors indicated that large numbers of Panzer V tanks were being used. To determine whether this was true, the Allies attempted to estimate the number of tanks being produced, to do this, they used the serial numbers on captured or destroyed tanks. The principal numbers used were gearbox numbers, as fell in two unbroken sequences. Chassis and engine numbers were used, though their use was more complicated. Various other components were used to cross-check the analysis, Similar analyses were done on wheels, which were observed to be sequentially numbered. The analysis of tank wheels yielded an estimate for the number of molds that were in use. A discussion with British road wheel makers then estimated the number of wheels that could be produced from this many molds, analysis of wheels from two tanks yielded an estimate of 270 tanks produced in February 1944, substantially more than had previously been suspected. German records after the war showed production for the month of February 1944 was 276, estimating production was not the only use of this serial-number analysis. According to conventional Allied intelligence estimates, the Germans were producing around 1,400 tanks a month between June 1940 and September 1942, applying the formula below to the serial numbers of captured tanks, the number was calculated to be 256 a month. After the war, captured German production figures from the ministry of Albert Speer showed the number to be 255. Estimates for some specific months are given as, Similar serial-number analysis was used for military equipment during World War II. Factory markings on Soviet military equipment were analyzed during the Korean War, in the 1980s, some Americans were given access to the production line of Israels Merkava tanks. The production numbers were classified, but the tanks had serial numbers, the formula has been used in non-military contexts, for example to estimate the number of Commodore 64 computers built, where the result matches the low-end estimates

C++
–
C++ is a general-purpose programming language. It has imperative, object-oriented and generic programming features, while also providing facilities for low-level memory manipulation and it was designed with a bias toward system programming and embedded, resource-constrained and large systems, with performance, efficiency and flexibility of use as its design highlights. C++ is a language, with implementations of it available on many platforms and provided by various organizations, including the Free Software Foundation, LLVM, Microsoft, Intel. C++ is standardized by the International Organization for Standardization, with the latest standard version ratified and published by ISO in December 2014 as ISO/IEC14882,2014. The C++ programming language was standardized in 1998 as ISO/IEC14882,1998. The current C++14 standard supersedes these and C++11, with new features, the C++17 standard is due in 2017, with the draft largely implemented by some compilers already, and C++20 is the next planned standard thereafter. Many other programming languages have influenced by C++, including C#, D, Java. In 1979, Bjarne Stroustrup, a Danish computer scientist, began work on C with Classes, the motivation for creating a new language originated from Stroustrups experience in programming for his Ph. D. thesis. When Stroustrup started working in AT&T Bell Labs, he had the problem of analyzing the UNIX kernel with respect to distributed computing, remembering his Ph. D. experience, Stroustrup set out to enhance the C language with Simula-like features. C was chosen because it was general-purpose, fast, portable, as well as C and Simulas influences, other languages also influenced C++, including ALGOL68, Ada, CLU and ML. Initially, Stroustrups C with Classes added features to the C compiler, Cpre, including classes, derived classes, strong typing, inlining, furthermore, it included the development of a standalone compiler for C++, Cfront. In 1985, the first edition of The C++ Programming Language was released, the first commercial implementation of C++ was released in October of the same year. In 1989, C++2.0 was released, followed by the second edition of The C++ Programming Language in 1991. New features in 2.0 included multiple inheritance, abstract classes, static functions, const member functions. In 1990, The Annotated C++ Reference Manual was published and this work became the basis for the future standard. Later feature additions included templates, exceptions, namespaces, new casts, after a minor C++14 update released in December 2014, various new additions are planned for 2017 and 2020. According to Stroustrup, the name signifies the nature of the changes from C. This name is credited to Rick Mascitti and was first used in December 1983, when Mascitti was questioned informally in 1992 about the naming, he indicated that it was given in a tongue-in-cheek spirit

ALGOL 68
–
ALGOL68 was designed by the IFIP Working Group 2.1. On December 20,1968, the language was adopted by Working Group 2.1. ALGOL68 was defined using a grammar formalism invented by Adriaan van Wijngaarden. ALGOL68 has been criticized, most prominently by some members of its design such as C. A. R. In 1970, ALGOL 68-R became the first working compiler for ALGOL68, in the 1973 revision, certain features – such as proceduring, gommas and formal bounds – were omitted. The language of the unrevised report, steve Bourne, who was on the Algol 68 revision committee, took some of its ideas to his Bourne shell and to C. The complete history of the project can be found in C. H, lindseys A History of ALGOL68. For a full-length treatment of the language, see Programming Algol 68 Made Easy by Dr. Sian Mountbatten, or Learning Algol 68 Genie by Dr. Marcel van der Veer which includes the Revised Report.

The basic language construct is the unit, a unit may be a formula, an enclosed clause, a routine text or one of several technically needed constructs. The technical term enclosed clause unifies some of the inherently bracketing constructs known as block, do statement, when keywords are used, generally the reversed character sequence of the introducing keyword is used for terminating the enclosure, e. g

Name
–
A name is a term used for identification. Names can identify a class or category of things, or a thing, either uniquely. A personal name identifies, not necessarily uniquely, an individual human. The name of an entity is sometimes called a proper name and is, when consisting of only one word. Other nouns are sometimes called names or general names. A name can be given to a person, place, or thing, for example, caution must be exercised when translating, for there are ways that one language may prefer one type of name over another. Also, claims to preference or authority can be refuted, the British did not refer to Louis-Napoleon as Napoleon III during his rule. The word name comes from Old English nama, cognate with Old High German namo, Sanskrit नामन्, Latin nomen, Greek ὄνομα, perhaps connected to non-Indo-European terms such as Tamil namam and Proto-Uralic *nime. In the ancient world, particularly in the ancient near-east names were thought to be powerful and to act, in some ways. By invoking a god or spirit by name, one was thought to be able to summon that spirits power for some kind of miracle or magic, in the Old Testament, the names of individuals are meaningful, and a change of name indicates a change of status. For example, the patriarch Abram and his wife Sarai are renamed Abraham, simon was renamed Peter when he was given the Keys to Heaven. This is recounted in the Gospel of Matthew chapter 16, which according to Roman Catholic teaching was when Jesus promised to Saint Peter the power to take binding actions. Throughout the Bible, characters are given names at birth that reflect something of significance or describe the course of their lives, for example, Solomon meant peace, and the king with that name was the first whose reign was without war. Likewise, Joseph named his firstborn son Manasseh, when Joseph also said, “God has made me all my troubles. However, they were known as the child of their father. For example, דוד בן ישי meaning, David, son of Jesse, the Talmud also states that all those who descend to Gehenna will rise in the time of Messiah. However, there are three exceptions, one of which is he who calls another by a derisive nickname, Street names within a city may follow a naming convention, some examples include, In Manhattan, roads that cross the island from east to west are called Streets. Those that run the length of the island are called Avenues, in Ontario, numbered concession roads are east–west whereas lines are north–south routes

Synonym
–
A synonym is a word or phrase that means exactly or nearly the same as another word or phrase in the same language. Words that are synonyms are said to be synonymous, and the state of being a synonym is called synonymy, the word comes from Ancient Greek sýn and ónoma. An example of synonyms are the words begin, start, commence, words can be synonymous when meant in certain senses, even if they are not synonymous in all of their senses. For example, if one talks about a time or an extended time, long. Some academics call the former type cognitive synonyms to distinguish them from the latter type, some lexicographers claim that no synonyms have exactly the same meaning because etymology, orthography, phonic qualities, ambiguous meanings, usage, etc. make them unique. Different words that are similar in meaning usually differ for a reason, feline is more formal than cat, long and extended are only synonyms in one usage, synonyms are also a source of euphemisms. In the figurative sense, two words are said to be synonymous if they have the same connotation. a widespread impression that. Metonymy can sometimes be a form of synonymy, as when, for example, thus a metonym is a type of synonym, and the word metonym is a hyponym of the word synonym. The analysis of synonymy, polysemy, hyponymy, and hypernymy is inherent to taxonomy and it has applications in pedagogy and machine learning, because they rely on word-sense disambiguation and schema. Synonyms can be any part of speech, as long as both words belong to the part of speech. Such like, he expired means the same as he died, in English, many synonyms emerged in the Middle Ages, after the Norman conquest of England. While Englands new ruling class spoke Norman French, the lower classes continued to speak Old English, thus, today we have synonyms like the Norman-derived people, liberty and archer, and the Saxon-derived folk, freedom and bowman. For more examples, see the list of Germanic and Latinate equivalents in English, the purpose of a thesaurus is to offer the user a listing of similar or related words, these are often, but not always, synonyms. The word poecilonym is a synonym of the word synonym. It is not entered in most major dictionaries and is a curiosity or piece of trivia for being a word because of its meta quality as a synonym of synonym. Antonyms are words with opposite or nearly opposite meanings, for example, hot ↔ cold, large ↔ small, thick ↔ thin, synonym ↔ antonym Hypernyms and hyponyms are words that refer to, respectively, a general category and a specific instance of that category. For example, vehicle is a hypernym of car, and car is a hyponym of vehicle, homophones are words that have the same pronunciation, but different meanings. For example, witch and which are homophones in most accents, homographs are words that have the same spelling, but have different pronunciations

Netscape
–
When it was an independent company, its headquarters were in Mountain View, California. Netscapes web browser was dominant in terms of usage share. The usage share of Netscape had fallen from over ninety percent in the mid-1990s to less than one percent by the end of 2006, Netscape stock traded from 1995 until 1999 when it was acquired by AOL in a pooling-of-interests transaction ultimately worth US $10 billion. Shortly before its acquisition by AOL, Netscape released the code for its browser. The Mozilla Organization rewrote the entire source code based on the Gecko rendering engine. The Gecko engine would later be used to power the Mozilla Foundations Firefox browser, under AOL, Netscapes browser development continued until December 2007 when AOL announced that the company would stop supporting the Netscape browser as of early 2008. As of 2011, AOL has continued to use the Netscape brand to market a discount Internet service provider, Netscape was the first company to attempt to capitalize on the nascent World Wide Web. The first meeting between Clark and Andreessen was never truly about a software or service like Netscape, but more about a product that was similar to Nintendo, Clark recruited other early team members from SGI and NCSA Mosaic. Jim Barksdale came on board as CEO in January 1995, jim Clark and Marc Andreessen originally created a 20-page concept pitch for an online gaming network to Nintendo for the Nintendo 64 console, but a deal was never reached. Marc Andreessen explains, If they had shipped a year earlier, the companys first product was the web browser, called Mosaic Netscape 0.9, released on October 13,1994. Within four months of its release, it had already taken three-quarters of the browser market and it became the main browser for Internet users in such a short time due to its superiority over other competition, like Mosaic. The Mosaic Netscape web browser did not use any NCSA Mosaic code, the internal codename for the companys browser was Mozilla, which stood for Mosaic killer, as the companys goal was to displace NCSA Mosaic as the worlds number one web browser. A cartoon Godzilla-like lizard mascot was drawn by artist-employee Dave Titus, the Mozilla mascot featured prominently on Netscapes web site in the companys early years. However, the need to project a professional image led to this being removed. On August 9,1995, Netscape made an extremely successful IPO, the stock was set to be offered at US$14 per share, but a last-minute decision doubled the initial offering to US$28 per share. The stocks value soared to US$75 during the first day of trading, the stock closed at US$58.25, which gave Netscape a market value of US$2.9 billion. While it was unusual for a company to go public prior to becoming profitable, Netscapes revenues had, in fact, the success of this IPO subsequently inspired the use of the term Netscape moment to describe a high-visibility IPO that signals the dawn of a new industry. During this period, Netscape also pursued a publicity strategy packaging Andreessen as the rock star

Unicode
–
Unicode is a computing industry standard for the consistent encoding, representation, and handling of text expressed in most of the worlds writing systems. As of June 2016, the most recent version is Unicode 9.0, the standard is maintained by the Unicode Consortium. Unicodes success at unifying character sets has led to its widespread, the standard has been implemented in many recent technologies, including modern operating systems, XML, Java, and the. NET Framework. Unicode can be implemented by different character encodings, the most commonly used encodings are UTF-8, UTF-16 and the now-obsolete UCS-2. UTF-8 uses one byte for any ASCII character, all of which have the same values in both UTF-8 and ASCII encoding, and up to four bytes for other characters. UCS-2 uses a 16-bit code unit for each character but cannot encode every character in the current Unicode standard, UTF-16 extends UCS-2, using one 16-bit unit for the characters that were representable in UCS-2 and two 16-bit units to handle each of the additional characters. Many traditional character encodings share a common problem in that they allow bilingual computer processing, Unicode, in intent, encodes the underlying characters—graphemes and grapheme-like units—rather than the variant glyphs for such characters. In the case of Chinese characters, this leads to controversies over distinguishing the underlying character from its variant glyphs. In text processing, Unicode takes the role of providing a unique code point—a number, in other words, Unicode represents a character in an abstract way and leaves the visual rendering to other software, such as a web browser or word processor. This simple aim becomes complicated, however, because of concessions made by Unicodes designers in the hope of encouraging a more rapid adoption of Unicode, the first 256 code points were made identical to the content of ISO-8859-1 so as to make it trivial to convert existing western text. For other examples, see duplicate characters in Unicode and he explained that he name Unicode is intended to suggest a unique, unified, universal encoding. In this document, entitled Unicode 88, Becker outlined a 16-bit character model, Unicode could be roughly described as wide-body ASCII that has been stretched to 16 bits to encompass the characters of all the worlds living languages. In a properly engineered design,16 bits per character are more than sufficient for this purpose, Unicode aims in the first instance at the characters published in modern text, whose number is undoubtedly far below 214 =16,384. By the end of 1990, most of the work on mapping existing character encoding standards had been completed, the Unicode Consortium was incorporated in California on January 3,1991, and in October 1991, the first volume of the Unicode standard was published. The second volume, covering Han ideographs, was published in June 1992, in 1996, a surrogate character mechanism was implemented in Unicode 2.0, so that Unicode was no longer restricted to 16 bits. The Microsoft TrueType specification version 1.0 from 1992 used the name Apple Unicode instead of Unicode for the Platform ID in the naming table, Unicode defines a codespace of 1,114,112 code points in the range 0hex to 10FFFFhex. Normally a Unicode code point is referred to by writing U+ followed by its hexadecimal number, for code points in the Basic Multilingual Plane, four digits are used, for code points outside the BMP, five or six digits are used, as required. Code points in Planes 1 through 16 are accessed as surrogate pairs in UTF-16, within each plane, characters are allocated within named blocks of related characters
