Corona (software)

Corona SDK is a software development kit (SDK) created by Walter Luh, Founder of Corona Labs Inc.. Corona SDK allows software programmers to build mobile applications for iPhone, iPad, and Android devices.

Corona lets developers use integrated Lua, layered on top of C++/OpenGL, to build graphic applications. The SDK does not charge per-app royalty or impose any branding requirement, and has a subscription-based purchase model.

History

Walter Luh started Corona Labs after departing from Adobe in 2007. At Adobe, Luh was the lead architect working on the Flash Lite team. In June 2009, Luh released the first Corona SDK beta free for early adopters.

In December 2009, Corona Labs launched Corona SDK 1.0 for iPhone. The following February, the Corona SDK 1.1 was released with additional features.

In April 2010, the Corona SDK 2.0 beta was released. Corona 2.0's definitive new feature was cross-platform support for iPhone, iPad, and Android devices. Later that month, Corona Labs announced a beta for Corona Game Edition, which includes a physics engine and other advanced features aimed specifically at game development.<ref name=""CoronaLabsBlog2">"Introducing Corona Game Edition - Corona Labs company blog, April 23, 2010".

Corona

A corona (Latin, 'crown') is an aura of plasma that surrounds the sun and other celestial bodies. The Sun's corona extends millions of kilometres into space and is most easily seen during a total solar eclipse, but it is also observable with a coronagraph. The word "corona" is a Latin word meaning "crown", from the Ancient Greek κορώνη (korōnè, “garland, wreath”).

The high temperature of the Sun's corona gives it unusual spectral features, which led some in the 19th century to suggest that it contained a previously unknown element, "coronium". Instead, these spectral features have since been explained by highly ionized iron (Fe-XIV). Bengt Edlén, following the work of Grotrian (1939), first identified the coronal lines in 1940 (observed since 1869) as transitions from low-lying metastable levels of the ground configuration of highly ionised metals (the green Fe-XIV line at 5303 Å, but also the red line Fe-X at 6374 Å). These high stages of ionisation indicate a plasma temperature in excess of 1,000,000 kelvin, much hotter than the surface of the sun.

Getting Started

Getting Started is a 1979 animated short by Richard Condie and produced in Winnipeg by the National Film Board of Canada.

The film is a comical look at procrastination, based partly on the filmmaker's own experiences, portraying the inability of a pianist to rehearse a Debussy composition.

Awards for Getting Started included the Genie Award for best animation film. The film also won awards at the Zagreb World Festival of Animated Films and the Tampere Film Festival, as well as a "Bijou" at the Canadian Short Film and Television Awards.
