Antarctica has no indigenous population and there is no evidence that it was seen by humans until the 19th century. However, belief in the existence of a Terra Australisa vast continent in the far south of the globe to "balance" the northern lands of Europe, Asia and North Africahad existed since the times of Ptolemy (1st century AD), who suggested the idea to preserve the symmetry of all known landmasses in the world. Even in the late 17th century, after explorers had found that South America and Australia were not part of the fabled "Antarctica", geographers believed that the continent was much larger than its actual size.
What continent has an indigenous population that arrived in the 19th century?
A: unanswerable

PS3's hardware has also been used to build supercomputers for high-performance computing. Fixstars Solutions sells a version of Yellow Dog Linux for PlayStation 3 (originally sold by Terra Soft Solutions). RapidMind produced a stream programming package for PS3, but were acquired by Intel in 2009. Also, on January 3, 2007, Dr. Frank Mueller, Associate Professor of Computer science at NCSU, clustered 8 PS3s. Mueller commented that the 256 MB of system RAM is a limitation for this particular application and is considering attempting to retrofit more RAM. Software includes: Fedora Core 5 Linux ppc64, MPICH2, OpenMP v 2.5, GNU Compiler Collection and CellSDK 1.1. As a more cost-effective alternative to conventional supercomputers, the U.S. military has purchased clusters of PS3 units for research purposes. Retail PS3 Slim units cannot be used for supercomputing, because PS3 Slim lacks the ability to boot into a third-party OS.
Who did RapidMind acquire in 2009?
A: unanswerable

Simple stepper motor drivers entirely energize or entirely de-energize the field windings, leading the rotor to "cog" to a limited number of positions; more sophisticated drivers can proportionally control the power to the field windings, allowing the rotors to position between the cog points and thereby rotate extremely smoothly. This mode of operation is often called microstepping. Computer controlled stepper motors are one of the most versatile forms of positioning systems, particularly when part of a digital servo-controlled system.
What is another name for smooth rotation?
A: microstepping

Douglas's business grew astronomically with the onset of World War II, employing as many as 44,000 people in 1943. To defend against air attack set designers from the Warner Brothers Studios prepared elaborate camouflage that disguised the factory and airfield. The RAND Corporation began as a project of the Douglas Company in 1945, and spun off into an independent think tank on May 14, 1948. RAND eventually acquired a 15-acre (61,000 m) campus centrally located between the Civic Center and the pier entrance.
What company started as a project in 1945?
A:
RAND
