Combinatorial auctions could make online auctions more efficient as well as more fair to buyers and sellers.
The Pentagon had proposed a terror futures market in which traders could place money on where they believe the next terrorist attack will take place. I like this idea, given what we know about markets' abilities to synthesize obscure information efficiently. Unfortunately, this idea was nixed after political opposition.
Physicists used to argue about what would happen if a submarine travelled close to the speed of light. Would the relativistic effects make it float or sink? They now know the answer.

Spam filter report: Following the examples of Hanah Metchis and Diana, I've been trying out the free open source Bayesian spam filter POPFile. Because it's a Bayesian filter it needs to be trained, so for the past month I've had POPFile sort all of my incoming mail into one of three groups or "buckets" -- "personal" (for genuine personal e-mail), "lists" (for bulk e-mail that I have voluntarily signed up for, such as mailing lists or announcements from certain vendors), and "spam" (all the unsolicited junk). After the training period, I then reset the counter statistics and let POPFile sort the next 1000 consecutive e-mails. To my dismay, my incoming mail consisted of 69% spam, 23% list mail, and only 8% "real" e-mail. Overall, POPFile did pretty well -- it classified over 96% of my mail correctly. Now I don't mind an occasional spam being misclassified as "personal", but it's more of a problem when the filter misclassifies a real e-mail as "spam", which still happens about once every 2-3 days. Since I don't want to take the chance of missing something important, I still take a look at my "spam" bucket once a day and quickly skim the subject lines before I delete the contents. But overall, I'm pretty pleased -- it's easy to set up, it does a surprisingly good job, and it has saved me a fair amount of daily aggravation. Plus you can't beat the price!

Beware the public computers: For the past two years, a NYC cracker has been stealing banking passwords from keystroke sniffers he planted at 13 Kinko's stores in Manhattan. He was finally caught when "he had the bad luck to use a stolen GoToMyPC account to remotely control a victim's home computer while the victim was sitting in front of it. The victim, unnamed in court filings, watched as the PC's cursor began moving of its own accord, riffling through files, opening a browser window, and then establishing an account with online money transfer site Neteller.com under the victim's name. The victim had logged into the machine through GoToMyPC from a Kinko's on Seventh Avenue a few days earlier." Even more amazingly, after the cracker was charged and released on bail, he "got caught planting another keyboard sniffer at a Kinko's on West 40th Street in New York." (Via Ars Technica.)

What's your optimum strategy if you suspect you're living in a computer simulated virtual reality (like The Matrix), and you want to maximize your longevity? Robin Hanson's paper, "How to Live in a Simulation" tells you. The short answer -- "If you might be living in a simulation then all else equal you should care less about others, live more for today, make your world look more likely to become rich, expect to and try more to participate in pivotal events, be more entertaining and praiseworthy, and keep the famous people around you happier and more interested in you." For a more in-depth analysis, read the full paper.
My last word on the mosquito story: Stephen Wood was kind enough to point me to the following article from the "Straight Dope", basically saying that ultrasonic bug repellers don't work. If Uncle Cecil says it, it's gotta be true!...

Yet another mosquito update: Jason Salvatori wrote in to say, "I'm not sure about the power problem from a cell phone, but I do know that a radio station up here (Toronto, Canada) used to play the same ultrasonic frequency with its music in the summer, and it did seem to work! I haven't listned to that station in a couple of years, so I don't know if they still do it. (99.9 FM - "Mix 99.9")."

"The Neurochemistry of Psychedelic Experiences": One interesting tidbit from the article -- humans are "the only species that will voluntarily take a psychedelic drug again after having experienced the effects. Although laboratory animals such as rats or monkeys will readily self-admininister most other drugs abused by humans, including cocaine, heroin, amphetamine, nicotine and alcohol, they find psychedelic drugs highly aversive." (Via SciTech Daily.)
