On being as Creative as Possible
"When you stumble into the shower shortly after you wake, you’re able to relax and, because you’re still tired, you’re able toreconnect with your subconscious. I’ve found this state to be so helpful in solving problems that I’ve had to devise ways to take notes on the shower wall."
Classical music is very rhythmic and, oddly enough, predictable. Classical also usually has a slower tempo, less than 60 beats per minute, whereas pop and jazz have unpredictable variances in tone and rhythm and often a much faster tempo....
Vinod Menon, Professor of Psychiatry and Behavioral Sciences at Stanford University’s School of Medicine, has written an interestingarticle on the subject. In the paper, Menon writes about music’s effect on the brain during an MRI. To simplify, the brain performs better when predictable patterns are in the music. During sudden breaks in the sound, the brain reacts to check on what’s happening. Your brain turns its attention back to the music, rather than stays on what you were concentrating on.

spying capabilities cover up to 75 percent of US internet traffic
The question of how much contact the NSA has with internet traffic throughout the US is being raised again, this time by the Wall Street Journal. Yesterday The Atlantic took issue with the security agency's mathematics and 1.6 percent claim, while the WSJ report looks more closely at its reach into telecommunications companies. The mishmash of codenamed programs are said to cover up to 75 percent of US internet traffic, although the amount actually stored and accessed is much smaller. The main difference between the calculations may be due to the difference between what ISPs -- handing over data under FISA orders -- carry, and what the NSA specifically requests. Its capabilities mean it can pull a lot more than just metadata, with access to the actual content of what's sent back and forth becoming even more troubling as privacy violations exposed by its own audits come to light.
