Advanced Computer Techniques
Advanced Computer Techniques (ACT) was a computer software company most active from the early 1960s through the early 1990s that made software products, especially language compilers and related tools. It also engaged in information technology consulting, hosted service bureaus, and provided applications and services for behavioral health providers. ACT had two subsidiaries of note, InterACT and Creative Socio-Medics. Both writer Katharine Davis Fishman, in her 1981 book ''The Computer Establishment'', and computer science historian Martin Campbell-Kelly, in his 2003 volume ''From Airline Reservations to Sonic the Hedgehog: A History of the Software Industry'', have considered ACT an exemplar of the independent, middle-sized software development firms of its era, and the Charles Babbage Institute at the University of Minnesota has also viewed the company's history as important. Founding and early history Advanced Computer Techniques was founded in New York City in April 1962 by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), i ...

Dan Fylstra
Dan Fylstra is a pioneer of the software products industry. A graduate of the Massachusetts Institute of Technology, in 1975 he was a founding associate editor of ''Byte'' magazine. In 1978 he co-founded Personal Software, and that year reviewed the Commodore PET 2001 and TRS-80 Model I for ''Byte'' while studying for an MBA at the Harvard Business School, having ordered each almost immediately after release. Personal Software became the distributor of a new program called VisiCalc, the first-ever computer spreadsheet. In his marketing efforts Fylstra ran teaser ads in ''Byte'' that asked, considering electronic spreadsheets were an entirely new product category, "How did you ever do without it?" The VisiCalc-Apple connection suggested the hypothesis of the "killer app"—or the "software tail that wags the hardware dog." Once VisiCalc caught on, people came into computer stores asking for VisiCalc and then also the computer (the Apple II) they would need to run the program. Visi ...

Pascal (programming Language)
Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring. It is named in honour of the French mathematician, philosopher and physicist Blaise Pascal. Pascal was developed on the pattern of the ALGOL 60 language. Wirth was involved in the process to improve the language as part of the ALGOL X efforts and proposed a version named ALGOL W. This was not accepted, and the ALGOL X process bogged down. In 1968, Wirth decided to abandon the ALGOL X process and further improve ALGOL W, releasing this as Pascal in 1970. On top of ALGOL's scalars and arrays, Pascal enables defining complex datatypes and building dynamic and recursive data structures such as lists, trees and graphs. Pascal has strong typing on all objects, which means that one type of data cannot be converted to or interpreted as another without explicit conversi ...

COBOL
COBOL (; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is an imperative, procedural and, since 2002, object-oriented language. COBOL is primarily used in business, finance, and administrative systems for companies and governments. COBOL is still widely used in applications deployed on mainframe computers, such as large-scale batch and transaction processing jobs. However, due to its declining popularity and the retirement of experienced COBOL programmers, programs are being migrated to new platforms, rewritten in modern languages or replaced with software packages. Most programming in COBOL is now purely to maintain existing applications; however, many large financial institutions were still developing new systems in COBOL as late as 2006. COBOL was designed in 1959 by CODASYL and was partly based on the programming language FLOW-MATIC designed by Grace Hopper. It was created as part ...

Plaza Hotel
The Plaza Hotel (also known as The Plaza) is a luxury hotel and condominium apartment building in Midtown Manhattan in New York City. It is located on the western side of Grand Army Plaza, after which it is named, just west of Fifth Avenue, and is between 58th Street and Central Park South ( 59th Street), at the southeastern corner of Central Park. Its primary address is 768 Fifth Avenue, though the residential entrance is One Central Park South. The 21-story, French Renaissance-inspired château style building was designed by Henry Janeway Hardenbergh. The facade is made of marble at the base, with white brick covering the upper stories, and is topped by a mansard roof. The ground floor contains the two primary lobbies, as well as a corridor connecting the large ground-floor restaurant spaces, including the Oak Room, the Oak Bar, the Edwardian Room, the Palm Court, and the Terrace Room. The upper stories contain the ballroom and a variety of residential condominiums, condo- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Navy
The United States Navy (USN) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States. It is the largest and most powerful navy in the world, with the estimated tonnage of its active battle fleet alone exceeding the next 13 navies combined, including 11 allies or partner nations of the United States as of 2015. It has the highest combined battle fleet tonnage (4,635,628 tonnes as of 2019) and the world's largest aircraft carrier fleet, with eleven in service, two new carriers under construction, and five other carriers planned.

UNIVAC LARC
The UNIVAC LARC, short for the ''Livermore Advanced Research Computer'', is a mainframe computer designed to a requirement published by Edward Teller in order to run hydrodynamic simulations for nuclear weapon design. It was one of the earliest supercomputers. LARC supported multiprocessing with two CPUs (called ''Computer''s) and an input/output (I/O) Processor (called the ''Processor''). Two LARC machines were built, the first delivered to Livermore in June 1960, and the second to the Navy's David Taylor Model Basin. Both examples had only one ''Computer'', so no multiprocessor LARCs were ever built. The LARC CPUs were able to perform addition in about 4 microseconds, corresponding to about 250 kIPS speed. This made it the fastest computer in the world until 1962 when the IBM 7030 took the title. The 7030 started as IBM's entry to the LARC contest, but Teller chose the simpler Univac over the more risky IBM design. Description The LARC was a decimal mainframe computer ...

Lotus Software
Lotus Software (called Lotus Development Corporation before its acquisition by IBM) was an American software company based in Massachusetts; it was "offloaded" to India's HCL Technologies in 2018. Lotus is most commonly known for the Lotus 1-2-3 spreadsheet application, the first feature-heavy, user-friendly, reliable and WYSIWYG-enabled product to become widely available in the early days of the IBM PC, when there was no graphical user interface. Much later, in conjunction with Ray Ozzie's Iris Associates, Lotus also released a groupware and email system, Lotus Notes. IBM purchased the company in 1995 for US$3.5 billion, primarily to acquire Lotus Notes and to establish a presence in the increasingly important client–server computing segment, which was rapidly making host-based products such as IBM's OfficeVision obsolete. On December 6, 2018, IBM announced the sale of Lotus Software/Domino to HCL for $1.8 billion. History Lotus was founded in 1982 by partners Mitch ...
