Torturous questions

Republican candidates at last Tuesday’s debate were asked about a now tired hypothetical:

The questions in this round will be premised on a fictional, but we think plausible scenario involving terrorism and the response to it. Here is the premise: Three shopping centers near major U.S. cities have been hit by suicide bombers. Hundreds are dead, thousands injured. A fourth attack has been averted when the attackers were captured off the Florida coast and taken to Guantanamo Bay, where they are being questioned. U.S. intelligence believes that another larger attack is planned and could come at any time.

First question to you, Senator McCain. How aggressively would you interrogate those being held at Guantanamo Bay for information about where the next attack might be?

As an editorial in the Washington Post points out, only John McCain got the answer right: when you torture your prisoners you actually make things worse, both in terms of world opinion and in wasting time on the unreliable information it produces. The trouble is, Hume’s hypothetical is actually two questions: a surface question about torture and an emotional question about what the candidate would be willing to sacrifice in the name of security. Personally I’d like to see the second question made more explicit. For example, how about asking one of these:

  • “Would you be willing to saw off your left leg with no anesthetic to stop a terrorist attack?”
  • “If you could go back in time and murder the 5-year-old Osama bin Laden with your bare hands, would you do it?”
  • “Would you be willing to repeal the First Amendment if it would stop another 9/11-sized attack? What about the Second Amendment? Would you raise taxes? Would you give up your immortal soul? How about your chances for re-election?”

Or maybe we should make the whole question less hypothetical. How about this?

“Gentlemen, on your left is Jerry (dressed in an Osama bin Laden mask), who is holding device that in one minute will send a million volts through the chairs of 10 random people sitting in our audience. To your right you see a switch that will disable the device, but will also drop poor Mrs. Grinwald here into this vat of hungry sharks. The decision is yours, but please be prepared to explain your actions.

Our TV audience will then vote for their favorite response via SMS, and the top 5 candidates will go on to the next round of questions.”

They’re not customers, they’re a captive audience!

My local Shell station has decided to augment its super-low prices of just $3.60 a gallon with some alternate revenue: automatic full-video and audio advertisements blasted at you while you pump gas.

At least there’s some satisfaction in the movie trailer they were showing in the rotation — after being subjected to several annoying ads there’s something satisfying about seeing explosions playing out on your gas pump.

We can’t lose

President Bush on Border Security, 11/28/05:

And one of the best examples of success is the Arizona Border Control Initiative, which the government launched in 2004. In the first year of this initiative — now, listen to this, listen how hard these people are working here — agents in Arizona apprehended nearly 500,000 illegal immigrants, a 42-percent increase over the previous year.

President Bush on Border Security, 4/9/07:

In the months before Operation Jump Start, an average of more than 400 people a day were apprehended trying to cross here. The number has dropped to fewer than 140 a day. In other words, one way that the Border Patrol can tell whether or not we’re making progress is the number of apprehensions. When you’re apprehending fewer people, it means fewer are trying to come across…. We’re seeing similar results all across the southern border. The number of people apprehended for illegally crossing our southern border is down by nearly 30 percent this year. We’re making progress. And thanks for your hard work. It’s hard work, but necessary work.

Great visualization tools from GapMinder.org

Here’s a video of an incredible talk Hans Rosling gave at last year’s TED conference. On one level it’s a talk about trends in world health (Rosling is a professor of international health at the Karolinska Institute in Sweden), but at another level it’s about the need for much better visualization tools so people can make sense out of all the data we already have freely available in public databases. The whole talk is an example, using tools developed by the non-profit Rosling founded called Gapminder.

After watching the video, check out Gapminder World, being hosted by Google.

Wells Fargo pushing the envelope

Wells Fargo is using optical scanning and OCR to improve how their customers deposit checks in ATMs. No more empty envelope drawers and out-of-ink pens; now you just put all your checks and cash in a stack and insert it into the slot. The ATM automatically scans each one in, does optical character recognition to tell how much each is for and puts up a verification screen. After you correct the amounts, the machine will either spit out a receipt with a summary line for each transaction or a printed image of each scanned check. From their press release:

“With the new technology, you don’t need to spend time writing on an envelope or keying in a deposit amount. You just insert your money into a slot and the machine sorts, counts and verifies it,” said Jonathan Velline, head of Wells Fargo’s ATM Banking division. “Our Envelope-Free ATMs also converts paper checks into a digital image which then appears on the ATM screen and receipt, so you know your check was received. You can’t get this in the traditional envelope world.”

I used one of their machines in Alameda recently and it was pretty slick, though I had to insert each of my three checks individually since it couldn’t handle my differently-sized and somewhat wallet-wrinkled stack.

Wireless power

powercast-patent-fig.png

Powercast (formerly Firefly Power Technologies, and spin-off based on University of Pittsburgh research) made a splash at CES this year with their dime-sized receiver that harvests RF energy from a nearby wall-wart transmitter. Based on their patent and related tech from PITT, the technology looks pretty darned simple (so simple I’m surprised there’s not prior art, but then this isn’t my field). It’s basically just an antenna with a bunch of taps, each tap consisting of an inductor to resonate with the desired RF frequency and a rectifying diode to turn the energy into DC. That DC voltage is integrated across a series of capacitors, and stored in another capacitor.

I’ve not seen any detailed specs on how efficiency drops off with range from the transmitter, though a Businesses 2.0 write-up claims their range is only about 3 feet, with voltages too small for laptops but good enough for small devices. Their tech has also been tested for recharging wireless sensors at the Pittsburgh Zoo, and Philips is apparently coming out with a wirelessly-powered lightstick using the technology later this year.
