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. follow link
Avoid Simple Typos
If, like me, you find yourself typing 2911 in place of 2011 entirely too often, you can have Mac OS X (either Lion or Snow Leopard) fix such typos for you automatically. Just open the Language & Text pane of System Preferences, click the Text button at the top, and then add a text substitution by clicking the + button underneath the list. It won't work everywhere (for that you'll want a utility like Smile's TextExpander), but it should work in applications like Pages and TextEdit, and in Save dialog boxes.
