Literate Programming
Literate programming (LP) is a programming paradigm introduced in 1984 by Donald Knuth in which a computer program is given as an explanation of how it works in a natural language, such as English, interspersed (embedded) with snippets of macros and traditional source code, from which compilable source code can be generated. The approach is used in scientific computing and in data science routinely for reproducible research and open access purposes. Literate programming tools are used by millions of programmers today. The literate programming paradigm, as conceived by Donald Knuth, represents a move away from writing computer programs in the manner and order imposed by the compiler, and instead gives programmers macros to develop programs in the order demanded by the logic and flow of their thoughts. Literate programs are written as an exposition of logic in more natural language in which macros are used to hide abstractions and traditional source code, more like the text o ...

Literate Programming Book Cover
Literacy is the ability to read and write, while illiteracy refers to an inability to read and write. Some researchers suggest that the study of "literacy" as a concept can be divided into two periods: the period before 1950, when literacy was understood solely as alphabetical literacy (word and letter recognition); and the period after 1950, when literacy slowly began to be considered as a wider concept and process, including the social and cultural aspects of reading, writing, and functional literacy. Definition The range of definitions of literacy used by Non-governmental organization, NGOs, think tanks, and advocacy groups since the 1990s suggests that this shift in understanding from "discrete skill" to "social practice" is both ongoing and uneven. Some definitions remain fairly closely aligned with the traditional "ability to read and write" connotation, whereas others take a broader view: * The 2003 National Assessment of Adult Literacy (USA) included "quantitativ ...

Programmer
A programmer, computer programmer or coder is an author of computer source code someone with skill in computer programming. The professional titles Software development, ''software developer'' and Software engineering, ''software engineer'' are used for jobs that require a programmer. Identification Sometimes a programmer or job position is identified by the language used or target platform. For example, assembly language, assembly programmer, web developer. Job title The job titles that include programming tasks have differing connotations across the computer industry and to different individuals. The following are notable descriptions. A ''software developer'' primarily implements software based on specifications and fixes Software bug, bugs. Other duties may include code review, reviewing code changes and software testing, testing. To achieve the required skills for the job, they might obtain a computer science or associate degree, associate degree, attend a Cod ...

Notebook Interface
A notebook interface or computational notebook is a virtual notebook environment used for literate programming, a method of writing computer programs. Some notebooks are WYSIWYG environments including executable calculations embedded in formatted documents; others separate calculations and text into separate sections. Notebooks share some goals and features with spreadsheets and word processors but go beyond their limited data models. Modular notebooks may connect to a variety of computational back ends, called "kernels". Notebook interfaces are widely used for statistics, data science, machine learning, and computer algebra. At the notebook core is the idea of literate programming tools which "let you arrange the parts of a program in any order and extract documentation and code from the same source file.", the notebook takes this approach to a new level extending it with some graphic functionality and a focus on interactivity. According to Stephen Wolfram: "The idea of a not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web (programming System)
Web, traditionally styled WEB, is a computer programming system created by Donald E. Knuth as the first implementation of what he called "literate programming": his idea that one could create software as works of literature, by embedding source code in descriptive text, rather than the reverse. Unlike standard programming practice which relegates documentation to comments, the WEB approach is to write an article to document the making of the source code, and to include all the source code in that article, so as to be compilable therefrom. Philosophy The common practice in most programming languages is that the primary text is source code, optionally supplemented by descriptive text in the form of comments. Knuth proposed that making the descriptive text primary was putting things in an order more convenient for human readers, rather than the order demanded by compilers. Much like TeX articles, the Web source text is divided into sections according to documentation flow. For e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typography
Typography is the art and technique of Typesetting, arranging type to make written language legibility, legible, readability, readable and beauty, appealing when displayed. The arrangement of type involves selecting typefaces, Point (typography), point sizes, line lengths, line spacing, letter spacing, and Kerning, spaces between pairs of letters. The term ''typography'' is also applied to the style, arrangement, and appearance of the letters, numbers, and symbols created by the process. Type design is a closely related craft, sometimes considered part of typography; most typographers do not design typefaces, and some type designers do not consider themselves typographers. Typography also may be used as an ornamental and decorative device, unrelated to the communication of information. Typography is also the work of graphic designers, art directors, manga artists, comic book artists, and, now, anyone who arranges words, letters, numbers, and symbols for publication, display, ...

Algorithm
In mathematics and computer science, an algorithm () is a finite sequence of Rigour#Mathematics, mathematically rigorous instructions, typically used to solve a class of specific Computational problem, problems or to perform a computation. Algorithms are used as specifications for performing calculations and data processing. More advanced algorithms can use Conditional (computer programming), conditionals to divert the code execution through various routes (referred to as automated decision-making) and deduce valid inferences (referred to as automated reasoning). In contrast, a Heuristic (computer science), heuristic is an approach to solving problems without well-defined correct or optimal results.David A. Grossman, Ophir Frieder, ''Information Retrieval: Algorithms and Heuristics'', 2nd edition, 2004, For example, although social media recommender systems are commonly called "algorithms", they actually rely on heuristics as there is no truly "correct" recommendation.

Stanford University
Leland Stanford Junior University, commonly referred to as Stanford University, is a Private university, private research university in Stanford, California, United States. It was founded in 1885 by railroad magnate Leland Stanford (the eighth List of governors of California, governor of and then-incumbent List of United States senators from California, United States senator representing California) and his wife, Jane Stanford, Jane, in memory of their only child, Leland Stanford Jr., Leland Jr. The university admitted its first students in 1891, opening as a Mixed-sex education, coeducational and non-denominational institution. It struggled financially after Leland died in 1893 and again after much of the campus was damaged by the 1906 San Francisco earthquake. Following World War II, university Provost (education), provost Frederick Terman inspired an entrepreneurship, entrepreneurial culture to build a self-sufficient local industry (later Silicon Valley). In 1951, Stanfor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Language-independent Specification
A language-independent specification (LIS) is a programming language specification providing a common interface usable for defining semantics applicable toward arbitrary language bindings. LIS's are language-agnostic; they mitigate the risk that a certain language binding might reduce compatibility with other languages. An ideal LIS allows the language bindings to take advantage of features of a programming language uncompromisingly. Examples of LIS include Interface description language (IDL), Simplified Wrapper and Interface Generator (SWIG) and Common Language Infrastructure The Common Language Infrastructure (CLI) is an open specification and technical standard originally developed by Microsoft and standardized by International Organization for Standardization, ISO/International Electrotechnical Commission, IEC (ISO/ ... (CLI). Recursive transcompiling can be used to distribute a language independent specification across many different technologies, with each technol ...

Battle Of Flodden
The Battle of Flodden, Flodden Field, or occasionally Branxton or Brainston Moor was fought on 9 September 1513 during the War of the League of Cambrai between the Kingdom of England and the Kingdom of Scotland and resulted in an English victory. The battle was fought near Branxton, Northumberland, Branxton, in the county of Northumberland, in northern England, between an invading Scots army under King James IV of Scotland, James IV and an English army commanded by the Thomas Howard, 2nd Duke of Norfolk, Earl of Surrey. In terms of troop numbers, it was the largest battle ever fought between the two kingdoms.''The Seventy Greatest Battles of All Time''. Published by Thames & Hudson Ltd. 2005. Edited by Jeremy Black. pp. 95–97. . After besieging and capturing several English border castles, James encamped his invading army on a commanding hilltop position at Flodden, awaited the English force that had been sent against him and declined a challenge to fight in an open field.

Marmion (poem)
''Marmion: A Tale of Flodden Field'' is a historical romance in verse of 16th-century Scotland and England by Sir Walter Scott, published in 1808. Consisting of six cantos, each with an introductory epistle, and copious antiquarian notes, it concludes with the Battle of Flodden in 1513. Background The introductory epistle to the first canto of ''Marmion'' is internally dated November, and there is no reason to doubt that it was written in that month of 1806. At this time Scott was entering into correspondence with the Durham antiquary Robert Surtees, and in December they discussed the account given by Robert Lindsay of Pitscottie of the supernatural summons of James IV and several of his nobles to appear before Pluto, which Scott uses in the fifth canto: Scott refers to his developing poem, so it is clear that the overall shape of the work was clear from the outset. Moreover, Surtees sent Scott two forgeries of his own, an account in Latin of a ghostly combat and a ballad, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sir Walter Scott
Sir Walter Scott, 1st Baronet (15 August 1771 – 21 September 1832), was a Scottish novelist, poet and historian.
