AWK es un lenguaje de programación diseñado para procesar datos basados en texto, ya sean ficheros o flujos de datos. El nombre AWK deriva de las iniciales de los apellidos de sus autores: Alfred Aho, Peter Weinberger, y Brian Kernighan. awk, cuando está escrito todo en minúsculas, hace referencia al programa de Unix o Plan 9 que interpreta programas escritos en el lenguaje …

Ritchie es conocido sobre todo por ser el creador del lenguaje de programación C y cocreador, junto con Ken Thompson, del sistema operativo Unix. [6] [7] También fue coautor junto con Brian Kernighan del manual El lenguaje de programación C, que durante años fue el estándar de facto del lenguaje (conocido como K&R C), hasta la aparición del ANSI C.

1950s. 1951 LEO I 'Lyons Electronic Office' was the commercial development of EDSAC computing platform, supported by British firm J. Lyons and Co.; 1955 MIT's Tape Director operating system made for UNIVAC 1103; 1955 General Motors Operating System made for IBM 701; 1956 GM-NAA I/O for IBM 704, based on General Motors Operating System; 1957 Atlas …

Brian Kernighan (Bell Labs) A hybrid of C and Fortran, implemented as a preprocessor for environments without easy access to C compilers. AWK: 1977: Alfred Aho, Peter Weinberger & Brian Kernighan : Designed for text processing and typically used as a data extraction and reporting tool. C shell/tcsh: 1978: Bill Joy (UC Berkeley)

Shen Lin y Brian Kernighan publicaron por primera vez este método en 1972, y fue la heurística más confiable para resolver el problema del viajante por aproximadamente dos décadas. Otros avances de los métodos variable-opt fueron desarrollados en Laboratorios Bell a finales de los 80s por David Johnson y su equipo de investigación.

AWK (awk) is a domain-specific language designed for text processing and typically used as a data extraction and reporting tool. Like sed and grep, it is a filter, and is a standard feature of most Unix-like operating systems.. The AWK language is a data-driven scripting language consisting of a set of actions to be taken against streams of textual data – either run directly on files or used ...

Shellsort, also known as Shell sort or Shell's method, is an in-place comparison sort.It can be seen as either a generalization of sorting by exchange (bubble sort) or sorting by insertion (insertion sort).The method starts by sorting pairs of elements far apart from each other, then progressively reducing the gap between elements to be compared.

Unix, officiellement UNIX, est une famille de systèmes d'exploitation multitâche et multi-utilisateur dérivé du Unix d'origine créé par AT&T, le développement de ce dernier ayant commencé dans les années 1970 au centre de recherche de Bell Labs mené par Kenneth Thompson.Il repose sur un interpréteur ou superviseur (le shell) et de nombreux petits utilitaires, accomplissant chacun ...

grep is a command-line utility for searching plain-text data sets for lines that match a regular expression.Its name comes from the ed command g/re/p (globally search for a regular expression and print matching lines), which has the same effect. grep was originally developed for the Unix operating system, but later available for all Unix-like systems and some others such as OS-9.

Cette liste regroupe des informaticiens (concepteur, développeur, chercheur en informatique) ainsi que des mathématiciens ou théoriciens dont les travaux ont établi, avant l'invention des ordinateurs, les bases de l'informatique moderne (travaux sur l'algorithmique, la théorie de l'information ou la théorie de la complexité des algorithmes par exemple).

Recursion (adjective: recursive) occurs when a thing is defined in terms of itself or of its type.Recursion is used in a variety of disciplines ranging from linguistics to logic.The most common application of recursion is in mathematics and computer science, where a function being defined is applied within its own definition. While this apparently defines an infinite …

In computer programming, a static variable is a variable that has been allocated "statically", meaning that its lifetime (or "extent") is the entire run of the program. This is in contrast to shorter-lived automatic variables, whose storage is stack allocated and deallocated on the call stack; and in contrast to objects, whose storage is dynamically allocated and deallocated in heap memory.

Python (phát âm tiếng Anh: /ˈpaɪθɑːn/) là một ngôn ngữ lập trình bậc cao cho các mục đích lập trình đa năng, do Guido van Rossum tạo ra và lần đầu ra mắt vào năm 1991.Python được thiết kế với ưu điểm mạnh là dễ đọc, dễ học và dễ nhớ. Python là ngôn ngữ có hình thức rất sáng sủa, cấu trúc rõ ràng, thuận ...

When the Dominion of Canada was created in 1867, Hamilton was an enthusiastic partner in the bold new political enterprise and preached the joys of the British Empire.The city was represented in the House of Commons by one seat for the city proper and two for the remainder of the county (Wentworth South and Wentworth North)..
