The Space Shuttle contained a bulky printer so the astronauts could

Core i7 920 is of a different kind. First, it is not only clocked at a higher
speed (default 2,8 Ghz), it is also a quad-core processor. Thanks to the re-
introduction of hyperthreading, this processor...

HD-DVD may be dead, but Blu Ray is just as dead. The whole concept of optical

When configuring a Linux RAID array, the chunk size needs to get chosen. But

10 and so on), the chunk of data sent to the array is broken down in to
pieces, each part...
