“How Much Sleep Do You Actually Require (and Why)?”

I’ve always wondered about people who only sleep a few hours a day. I’ve found that I need at least seven and a half hours a day to feel rested (which usually means an afternoon nap since I can rarely stay asleep more than six hours at night). But it seems that a single brain …

“Kids, the Internet, and the End of Privacy”

In the small mid-western hick community where my family spent the early- to mid-eighties, you didn’t dare let people know you were different in any way. Fifties McCarthyism was still alive and well, but no communists presented themselves, so it was turned on anyone who was different in any way. Kids who couldn’t fit in …

“Assessing Terrorist Threats to Commercial Aviation”

I’ve talked more than a few times about terrorists, terrorism, and the TSA on this blog, often quoting security and cryptography expert Bruce Schneier. He’s posted links to a new article by a former airline advisor which sums up the problems with the TSA’s responses to date, and offers suggestions about how to do things …

“The cure for US job woes: More immigrants”

I’ve been baffled by this for the last couple days. I’m not sure I follow their numbers, but I’ll accept them on faith for the moment. The thing that baffles me is the source: a very conservative think-tank. Political conservatives have railed against anyone who was different practically since the ink was dry on the …

Spambots Revisited

Back at the beginning of April, I killed about a thousand spambot accounts on this blog and added some new defenses against them. Those defenses helped quite a bit; I was still getting about ten attempts a week, but any spambot that gave an invalid e-mail address got blocked, as was any that gave a …

“US spy drone hijacked with GPS spoof hack, report says”

Ever since I heard the report about the captured US spy-drone earlier this week, I wondered how it could possibly have happened. Well, my curiosity was satisfied today: it was reputedly caught by sending it false GPS signals — a vulnerability that military officials have apparently been aware of since at least 2003, and one …

Keeping Score of SF Author Predictions

SF authors generally make up their technologies based on the needs of the story they’re trying to tell, rather than based on reality, but the more “hard” science-oriented ones try to make their science as believable as possible too. This site seems to fit a common theme in this blog, of “track[ing] predictions and descriptions …

“One week playing violent video games alters brain activity”

More news on the effects of violent video games. Only preliminary results, but it’s something to keep an eye on. As a somewhat-related item: most of us figure out the difference between reality and make-believe when we’re very young. Apparently those who don’t end up in organizations like the Red Cross, which is considering accusing …

“Paul Krugman: save the economy by staging an alien invasion hoax”

A nice idea, but I suspect the execution would be pretty difficult. Hollywood special effects are a lot better now than in 1938, but there are many more science-educated people who would be a lot harder to fool too. All it would take is one slip-up, caught and pointed out by some bright teenager, and …
