Sandstorm (vehicle)
Sandstorm is an autonomous vehicle created by Carnegie Mellon University's Red Team, for the 2004 and 2005 DARPA Grand Challenge competition. It is a heavily modified 1986 M998 HMMWV.
Sandstorm qualified in first position in the 2004 DARPA Grand Challenge. It traveled the fastest and farthest (7.4 miles) during the race before high centering on an embankment.
The sensors used by Sandstorm in 2004 included three fixed LIDAR laser-ranging units, one steerable LIDAR (in the globe on top), a radar unit (developed in collaboration with the Duke University Robotics Team), and a pair of cameras for stereo vision. Sandstorm also had an Applanix POS/LV system, providing a GPS and inertial navigation system for determining geographical position.
Since the 2004 race Sandstorm has been continually tested and modified, logging hundreds of test miles. Testing includes an unprecedented continuous 200 mile test run at an average of 28 miles per hour.
The 2005 version of Sandstorm used six fixed LIDAR units, the steerable LIDAR, and short- and long-range radar.
Sand Storm (video game)
Sand Storm is a 1992 action game in which you are shooting an anti-air ballistic weapon. The premise of the game is similar to that of Sabotage. You must defend your home base from planes (which drop bombs), Patriot Missiles, and Scuds. If a missile or bomb touches the ground, some of the buildings in the base are damaged. Each building can be damaged three times. In other missions, you can direct a missile into designated enemy buildings.

Bedrock
In stratigraphy, bedrock is consolidated rock underlying the surface of a terrestrial planet, usually the Earth. Above the bedrock is usually an area of broken and weathered unconsolidated rock in the basal subsoil. The surface of the bedrock beneath soil cover is known as rockhead in engineering geology and identifying this, via excavations, drilling or geophysical methods, is an important task in most civil engineering projects. Superficial deposits (also known as drift) can be extremely thick, such that the bedrock lies hundreds of meters below the surface.
Bedrock may also experience subsurface weathering at its upper boundary, forming saprolite.
A solid geologic map of an area will usually show the distribution of differing bedrock types, i.e., rock that would be exposed at the surface if all soil or other superficial deposits were removed.
Soil scientists use the capital letters O, A, B, C, and E to identify the master soil horizons, and lowercase letters for distinctions of these horizons. Most soils have three major horizons—the surface horizon (A), the subsoil (B), and the substratum (C). Some soils have an organic horizon (O) on the surface, but such a horizon can also be buried. The master horizon, E, is used for subsurface horizons that have a significant loss of minerals (eluviation). Hard bedrock, which is not soil, uses the letter R.

Background
After being leaked in September 2009 to Lil Wayne fan sites, "BedRock" was finally released on November 14, 2009. It was originally titled "Girl You Know" (the fan sites to which the single was leaked titled it "BedRock/Girl You Know") and the chorus was sung by Omarion and Lil Wayne's verse was different, but due to Omarion's departure from Young Money, he was replaced by Lloyd. The song was originally planned to be released as the 3rd official single of the album, however due to popular demand by fans it was released as the 2nd single.
