The Economist explains: How can Twitter reveal your personality?
The Economist explains: How do two-factor logins improve security? Two-factor authentication relies on a combination of two separate credentials. One is typically a standard password. The other is a one-time passcode, often sent to a mobile phone. The method by which the code is delivered is "out of band" and cannot be intercepted by the attacker. Are you using two-factor (or multi-factor) authentication on your web apps?
Daryl Hannah, who we all know and love from Splash, also gets down and dirty. She was arrested back in 2009 in a protest against mountaintop removal, and she has supported various extreme environmental activists in their campaigns for renewable energy etc. She was arrested again in 2011 at the White House while protesting the Keystone oil pipeline. Damn, girl.
