Enter Dashboard, Expose, or Spaces Temporarily

Hold down F9, F10, F11, or F12 (or whatever you've set for the Expose and Spaces keyboard shortcuts) for a few seconds, and then release the key to enter and leave the appropriate mode without having to press the key again. This is particularly useful for Dashboard, in which you can check the contents of a widget and then return to your work with only a single key press.

Encryption Cracked by Listening to a Computer’s CPU

Send Article to a Friend

If this were a movie, we’d be laughing at the improbability of the premise — that encryption can be cracked by listening to the high-pitched sounds produced by a computer’s CPU as it decrypts data. But it’s real, and although it can be done at a distance of 4 meters with a parabolic microphone, the researchers (Daniel Genkin, Eran Tromer, and Adi Shamir, who is the S of the RSA cryptosystem) also showed that it could be done with a smartphone sitting next to a laptop. Upping the ante, they suggest that a microphone hidden inside a colocated server could eavesdrop on numerous nearby servers. In short, if security is paramount, both heavy-duty encryption and physical protection are necessary.favicon follow link
