Radiant (software)

Radiant is a free software content management system written in Ruby created and designed by John W. Long as a Ruby on Rails web application. While suitable for the non-technical user, it also provides elements for more advanced users.

Radiant has a lightweight core library with "extensions" providing additional customised functionality. Because extensions do not modify the core, upgrading is simplified; With over 200 extensions in the extension registry it can be adapted for a range of uses including membership management. All the content is stored inside a database. It is possible to use MySQL, PostgreSQL or SQLite. Radiant depends, like every Ruby on Rails application, on the installed adapters for the database.

It is distributed via a separate download or installable with RubyGems.

Two PHP ports of Radiant CMS are available as Frog CMS and Wolf CMS.

Design

Radiant projects are based on 3 elements: Pages, Snippets and Layouts.

Pages: Pages hold the body content and can include multiple page parts such as a sidebar. Radiant allows arrangement of pages according to any hierarchy. For example, if Radiant is used as a blog, all blog entries are Pages inside the Radiant system, arranged to reflect the actual structure of the content. For the non-technical user WYSIWYG Page editing is available as an extension

Radiant (album)

Radiant is the third studio album by Atlantic Starr. This collection featured the hit single "When Love Calls" and the quiet storm staples, "Send For Me" and "Am I Dreaming." Keith Sweat's group, Ol' Skool covered the song in 1998 featuring Sweat and R&B girl group Xscape on their eponymous debut album and Xscape's Traces of My Lipstick. This album also teamed them for the first time with veteran Motown producer James Anthony Carmichael, best known for his work with The Jackson 5 and The Commodores.

Radiant (novel)

Radiant is a science fiction novel by the Canadian author James Alan Gardner. It was published in 2004 by HarperCollins Publishers under their Eos Books imprint. It is the seventh novel in Gardner's "League of Peoples" series. Like the six preceding novels, Radiant is set in the middle of the 25th century; like most of them, it takes place in outer space and on alien planets, and features the continuing character Festina Ramos.

Backstory

In keeping with the series as a whole, Radiant shares the same backstory and conceptual background as the earlier books. Humanity has moved into the galaxy: based on a terraformed and bio-engineered New Earth, a human society called the Technocracy has developed an advanced, multi-planet, space-travelling society. The Technocracy explores space and colonizes new planets through its navy-like Outward Fleet and its Explorer Corps. Youn Suu, the novel's protagonist and first-person narrator, is a member of that Corps, as are the majority of the protagonists in Gardner's series. The Technocracy exists under the aegis of the League of Peoples, an umbrella organization of highly advanced alien beings that enforces a galactic peace and controls fatal violence against sentient beings in interstellar space.

Radiant (meteor shower)

The radiant or apparent radiant of a meteor shower is the point in the sky, from which (to a planetary observer) meteors appear to originate. The Perseids, for example, are meteors which appear to come from a point within the constellation of Perseus.

An observer might see such a meteor anywhere in the sky but the direction of motion, when traced back, will point to the radiant. A meteor that does not point back to the known radiant for a given shower is known as a sporadic and is not considered part of that shower.

Many showers have a radiant point that changes position during the interval when it appears. For example, the radiant point for the Delta Aurigids drifts by more than a degree per night.

Cause

Meteor showers are mostly caused by the trails of dust and debris left in the wake of a comet. This dust continues to move along the comet's wake, and when the Earth moves through such debris, a meteor shower results. Because all of the debris is moving in roughly the same direction, the meteors which strike the atmosphere all "point" back to the direction of the comet's path.
