Opera (web browser)

Opera is a web browser developed by Opera Software. The latest version is available for Microsoft Windows, OS X, and Linux operating systems, and uses the Blink layout engine. An earlier version using the Presto layout engine is still available, and additionally runs on FreeBSD systems.

Opera siblings – Opera Mobile, Opera Mini and Opera Coast – work on devices running Android, iOS, Windows Phone, Symbian, Maemo, Bada, BlackBerry and Windows Mobile operating systems, while Opera Mini runs on Java ME-capable devices.

According to Opera Software, the browser had more than 350 million users worldwide in the 4th quarter 2014. Total Opera mobile users reached 291 million in June 2015. Opera has been noted for originating many features later adopted by other web browsers. A prominent example is Speed Dial.

History

Opera began in 1994 as a research project at Telenor, the largest Norwegian telecommunications company. In 1995, it branched out into a separate company named Opera Software ASA. Opera was first released publicly with version 2.0 in 1996, which only ran on Microsoft Windows. In an attempt to capitalize on the emerging market for Internet-connected handheld devices, a project to port Opera to mobile device platforms was started in 1998. Opera 4.0, released in 2000, included a new cross-platform core that facilitated creation of editions of Opera for multiple operating systems and platforms.

Opera (Tosca album)

Opera is the debut studio album of Richard Dorfmeister and Rupert Huber's electronic music project Tosca. It combines new material and previously released singles, including "Chocolate Elvis". "Irresistibly funky" (BBC), "the blues, and the thick sultry bass, makes it as sexy and melancholy as cigarette smoke after a one-night stand in a strange city" (Mixmag). It is "one of the few sure things in a modest genre" (Sasha Frere-Jones, LA Weekly).

Connection

Whip (tree)

A whip is a slender, unbranched shoot or plant. This term is used in forestry to refer to unbranched young tree seedlings of approximately 0.5-1.0 m (1 ft 7 in-3 ft 3 in) in height and 2–3 years old that have been grown for planting out.

Swingout

The swingout is the defining dance move of Lindy Hop.

Background

The swingout evolved from the breakaway, which in turn evolved from the Texas Tommy. The first documented mention of the swingout pattern that resembles breakaway was in 1911, to describe a "Texas Tommy Swing" show done at the Fairmont Hotel in San Francisco. Its variants are used in Jive, East Coast Swing, West Coast Swing and Modern Jive.

Whipcracking

Whipcracking is the act of producing a cracking sound through the use of a whip. Used during livestock driving and horse riding, it has also become an art. A rhythmic whipcracking belongs to the traditional culture among various Germanic peoples of Bavaria (Goaßlschnalzen), various Alpine areas (Aperschnalzen), Austria, and Hungary (Ostorozás). Today it is a performing art, a part of rodeo show in United States, a competitive sport in Australia and increasingly popular in the United Kingdom, where it crosses boundaries of sport, hobby and performance.

Physics

The crack a whip makes is produced when a section of the whip moves faster than the speed of sound creating a small sonic boom. The creation of the sonic boom was confirmed in 1958 by analyzing the high-speed shadow photography taken in 1927.

Recently, an additional, purely geometrical factor was recognized: the tip of the whip moves twice as fast at the loop of the whip, just like the top of a car's wheel moves twice as fast as the car itself.
