Symbol

A symbol is a person or a concept that represents, stands for or suggests another idea, visual image, belief, action or material entity. Symbols take the form of words, sounds, gestures, ideas or visual images and are used to convey other ideas and beliefs. For example, a red octagon may be a symbol for "STOP". On a map, a blue line might represent a river. Numerals are symbols for numbers. Alphabetic letters may be symbols for sounds. Personal names are symbols representing individuals. A red rose may symbolize love and compassion. The variable x in a mathematical equation may symbolize the position of a particle in space.

In cartography, an organized collection of symbols forms a legend for a map.

Etymology

The word derives from the Greek symbolon (σύμβολον) meaning token or watchword. It is an amalgam of syn- "together" + bole "a throwing, a casting, the stroke of a missile, bolt, beam." The sense evolution in Greek is from "throwing things together" to "contrasting" to "comparing" to "token used in comparisons to determine if something is genuine." Hence, "outward sign" of something. The meaning "something which stands for something else" was first recorded in 1590, in Edmund Spenser's Faerie Queene.

Directory (computing)

In computing, a directory is a file system cataloging structure which contains references to other computer files, and possibly other directories. On many computers, directories are known as folders, catalogs (catalog was used on the Apple II, the Commodore 128 and some other early home computers as a command for displaying disk contents; the filesystems used by these did not support hierarchal directories), or drawers to provide some relevancy to a workbench or the traditional office file cabinet.

Files are organized by storing related files in the same directory. In a hierarchical filesystem (that is, one in which files and directories are organized in a manner that resembles a tree), a directory contained inside another directory is called a subdirectory. The terms parent and child are often used to describe the relationship between a subdirectory and the directory in which it is cataloged, the latter being the parent. The top-most directory in such a filesystem, which does not have a parent of its own, is called the root directory.

John Lee Hooker

John Lee Hooker (August 22, 1917 – June 21, 2001) was an American blues singer, songwriter and guitarist. He was born in Mississippi, the son of a sharecropper, and rose to prominence performing an electric guitar-style adaptation of Delta blues. Hooker often incorporated other elements, including talking blues and early North Mississippi Hill country blues. He developed his own driving-rhythm boogie style, distinct from the 1930s–1940s piano-derived boogie-woogie style. Some of his best known songs include "Boogie Chillen'" (1948), "Crawling King Snake" (1949), "Dimples" (1956), "Boom Boom" (1962), and "One Bourbon, One Scotch, One Beer" (1966) – the first being the most popular race record of 1949.

Early life

There is some debate as to the year of Hooker's birth in Coahoma County, Mississippi, the youngest of the eleven children of William Hooker (1871–1923), a sharecropper and Baptist preacher, and Minnie Ramsey (born 1875, date of death unknown); according to his official website, he was born on August 22, 1917.

Bob Dylan

Bob Dylan (/ˈdɪlən/; born Robert Allen Zimmerman, May 24, 1941) is an American singer-songwriter, artist and writer. He has been influential in popular music and culture for more than five decades. Much of his most celebrated work dates from the 1960s when his songs chronicled social unrest, although Dylan repudiated suggestions from journalists that he was a spokesman for his generation. Nevertheless, early songs such as "Blowin' in the Wind" and "The Times They Are a-Changin'" became anthems for the American civil rights and anti-war movements. After he left his initial base in the American folk music revival, his six-minute single "Like a Rolling Stone" altered the range of popular music in 1965. His mid-1960s recordings, backed by rock musicians, reached the top end of the United States music charts while also attracting denunciation and criticism from others in the folk movement.

Dylan's lyrics have incorporated various political, social, philosophical, and literary influences. They defied existing pop music conventions and appealed to the burgeoning counterculture. Initially inspired by the performances of Little Richard, and the songwriting of Woody Guthrie, Robert Johnson, and Hank Williams, Dylan has amplified and personalized musical genres. His recording career, spanning 50 years, has explored the traditions in American song—from folk, blues, and country to gospel, rock and roll, and rockabilly to English, Scottish, and Irish folk music, embracing even jazz and the Great American Songbook. Dylan performs with guitar, keyboards, and harmonica. Backed by a changing line-up of musicians, he has toured steadily since the late 1980s on what has been dubbed the Never Ending Tour. His accomplishments as a recording artist and performer have been central to his career, but songwriting is considered his greatest contribution.
