A caldera is a large crater formed by a volcano. A caldera usually has a flat level surface at the bottom of the crater formed by the hardening of a lake of lava.

Yellowstone National Park is largely contained within the Yellowstone caldera, which is responsible for its many spectacular geological features.

Calderas around the World:

1) Iceland: Askja
2) California: Long Valley


Caldera is a technology company associated with the Linux and open source movement, including producing workstation and server distributions. It was founded by Ransom Love, and received start-up funding from Ray Noorda, former CEO of Novell. Unlike most other Linux companies, Caldera came to own the rights to the UNIX mark in 2001, as well as the SCO UNIX product line (a proprietary product for Intel computers that would be expected to compete directly with Linux).

In 2002, Caldera's management recognized that the majority of its profits were coming from the legacy SCO flavor of UNIX, and renamed the company the SCO Group. Love later left the company. In January of the following year, SCO retained lawyer David Boies, announcing that they would be investigating infringement on their intellectual property pertaining to their ownership of UNIX. On March 7 of the following year, CEO Darl McBride announced that they were suing IBM over its contributions to Linux, claiming that IBM stole UNIX trade secrets and gave them to Linux kernel developers.
