| - | It seems we are being spied on everywhere. When the world doesn't feel safe, schools and businesses revert to using electronic surveillance. Generally this consists of hidden cameras. Sometimes there are even hidden bathroom cameras. | + | ====== Benchmarks ====== |

| - | [url="http://www.geocities.com/hentaioza/"]bathroom hidden camera[/url] | + | A benchmark is a test that measures the performance of a system or subsystem on a well-defined task or set of tasks. Benchmarks can be used to measure general things, like graphics, I/O, computing (integer and floating point), performance, etc. But most measure more specific tasks, like rendering polygons, reading and writing files, or performing operations on matrixes. |

| - | Schools are using surveillance more and more frequently. This is supposed to help keep students safe. It also helps to solve crimes that have already occurred. Knowing cameras are there causes students to think before engaging in misbehavior. | + | |
