Arthur Whitney (computer Scientist)
Arthur Whitney (born October 20, 1957) is a Canadian computer scientist most notable for developing three programming languages inspired by APL: A+, k, and q, and for co-founding the U.S. companies Kx Systems and Shakti Software. Career Whitney studied pure mathematics at the graduate level at the University of Toronto in the early 1980s. He then worked at Stanford University. He was first exposed to APL when he was 11 by its inventor, Ken Iverson, a family friend. He later worked extensively with APL, first at I. P. Sharp Associates alongside Ken Iverson and Roger Hui among others. Whitney is recognized as having had an "enduring and significant influence on APL" and he co-authored papers with both Ken Iverson and Roger Hui. He also wrote the initial prototype of J, a terse and macro-heavy single page of code, in one afternoon, which then served as the model for J implementor, Roger Hui, and was responsible for suggesting the rank operators in J. In 1988, Whitney bega ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Science
Computer science is the study of computation, information, and automation. Computer science spans Theoretical computer science, theoretical disciplines (such as algorithms, theory of computation, and information theory) to Applied science, applied disciplines (including the design and implementation of Computer architecture, hardware and Software engineering, software). Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of computational problem, problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and preventing security vulnerabilities. Computer graphics (computer science), Computer graphics and computational geometry address the generation of images. Programming language theory considers different ways to describe computational processes, and database theory concerns the management of re ...

Kenneth E
Kenneth is a given name of Gaelic origin. The name is an Anglicised form of two entirely different Gaelic personal names: ''Cainnech'' and '' Cináed''. The modern Gaelic form of ''Cainnech'' is ''Coinneach''; the name was derived from a byname meaning "handsome", "comely". Etymology The second part of the name ''Cinaed'' is derived either from the Celtic ''*aidhu'', meaning "fire", or else Brittonic ''jʉ:ð'' meaning "lord".

Canadian Computer Businesspeople
Canadians () are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity and Canadian values. Canada has also been strongly influenced by its linguistic, geographic, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Toronto Alumni
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities i ...

Union Bank Of Switzerland
Union Bank of Switzerland (UBS) was a Swiss Investment banking, investment bank and financial services company located in Switzerland. The bank, which at the time was the second largest bank in Switzerland, merged with Swiss Bank Corporation in 1998 to become UBS. This merger formed what was then the largest bank in Europe and the second largest bank in the world. UBS was formed in 1912 through the merger of the Bank in Winterthur and Toggenburger Bank, both founded in the early 1860s. UBS then continued to grow through acquisitions, including Aargauische Kreditanstalt in 1919, in 1945, Interhandel, Interhandel Basel in 1967, Phillips & Drew in 1986, and Schröder, Münchmeyer, Hengst & Co. in 1997 among others. The historical UBS logo comprises the initials "UBS" horizontally, crossed by vertical "SBG", referring to the name of the bank in German. "UBS" ceased to be considered a representational abbreviation for the Union Bank of Switzerland after the bank's 1998 merger with S ...

Sun Microsystems
Sun Microsystems, Inc., often known as Sun for short, was an American technology company that existed from 1982 to 2010 which developed and sold computers, computer components, software, and information technology services. Sun contributed significantly to the evolution of several key computing technologies, among them Unix, Reduced instruction set computer, RISC processors, thin client computing, and virtualization, virtualized computing. At its height, the Sun headquarters were in Santa Clara, California (part of Silicon Valley), on the former west campus of the Agnews Developmental Center. Sun products included computer servers and workstations built on its own Reduced instruction set computer, RISC-based SPARC processor architecture, as well as on x86-based AMD Opteron and Intel Xeon processors. Sun also developed its own computer storage, storage systems and a suite of software products, including the Unix-based SunOS and later Solaris operating system, Solaris operating s ...

Mainframe Computer
A mainframe computer, informally called a mainframe or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing. A mainframe computer is large but not as large as a supercomputer and has more processing power than some other classes of computers, such as minicomputers, server (computing), servers, workstations, and personal computers. Most large-scale computer-system architectures were established in the 1960s, but they continue to evolve. Mainframe computers are often used as servers. The term ''mainframe'' was derived from the large cabinet, called a ''main frame'', that housed the central processing unit and main computer memory, memory of early computers. Later, the term ''mainframe'' was used to distinguish high-end commercial computers from less powerful machines. Design Modern mainfr ...

Rank (J Programming Language)
Rank is a generalization of looping as used in scalar (non- array-oriented) programming languages. It is also a generalization of '' mapcar'' in the language ''Lisp'' and ''map'' in modern functional programming languages, and a generalization of scalar extension, inner (matrix) product, and outer product in APL\360. The canonical implementation of rank may be the language '' J'', but it is also available in Dyalog APL, the International Organization for Standardization (ISO) technical standard on Extended APL, and NARS2000. Rank has several different meanings. In general, the concept of ''rank'' is used to treat an orthogonal array in terms of its subarrays. For example, a two-dimensional array may be dealt with at rank 2 as the entire matrix, or at rank 1 to work with its implicit one-dimensional columns or rows, or at rank 0 to work at the level of its individual atoms. *''Noun rank'' – The rank of a noun is a nonnegative integer. *''Verb rank'' – The rank of a verb is a ...
