Airport Security: Why It Failed
From Live Science:
Airport screening procedures failed for many reasons to catch the Nigerian man who aimed to blow up flight 253 as it approached Detroit. Scanners that might have spotted the explosives are not fully deployed, and even at airports where they exist, the scanners aren't used on all passengers.
Bottom line: No system will likely prove foolproof, experts say.
Investigators say 23-year-old Nigerian Umar Farouk Abdul Mutallab hid an explosive device and the chemical explosive PETN on his body while traveling from Amsterdam to Detroit aboard the Delta flight on Christmas day.

Once In A Blue Moon To Happen Thursday
Once in a blue moon is about to happen.
On Thursday, a second full moon in a calendar month will appear in the night sky, an occurrence known as a blue moon.
There has not been a month with two full moons since 2007, when sky gazers enjoyed one on June 1 and again on June 30 of that year. The first full moon this month occurred on Dec. 2.
The phrase "blue moon" has nothing to do with the color of the sphere, explained Conrad Jung, a staff astronomer at the Chabot Space & Science Center in Oakland. "It's just a colloquial term, which means very, very rare," he said.

Amazon: Kindle Is Most Gifted Item Ever
Amazon's Kindle e-book reader hit a watershed moment on Christmas Day, when, for the first time ever, customers purchased more Kindle books than physical books. The company also claims the Kindle is the most gifted item in Amazon's history. These two facts were part of the online retailer's recently announced holiday sales activity.
But in typical Amazon style, the company did not provide any sales figures to back up its claims. Although Amazon did say that if you placed side by side all the Blu-ray disc players the company sold this season, the line would stretch for more than 27 miles. A mile has 63,360 inches, so I'll leave you to make your best guess.

The Department of Mad Scientists -- A Book Review
Two years ago, in his book “Rocketeers,” Michael Belfiore celebrated the pioneers of the budding private space industry. Now he has returned to explore a frontier closer to home. The heroes of his new book, “The Department of Mad Scientists,” work for the Defense Advanced Research Projects Agency, better known as Darpa, a secretive arm of the United States government. And the revolution they’re leading is a merger of humans with machines.
The revolution is happening before our eyes, but we don’t recognize it, because it’s incremental. It starts with driving. Cruise control transfers regulation of your car’s speed to a computer. In some models, you can upgrade to adaptive cruise control, which monitors the surrounding traffic by radar and adjusts your speed accordingly. If you drift out of your lane, an option called lane keeping assistance gently steers you back. For extra safety, you can get extended brake assistance, which monitors traffic ahead of you, alerts you to collision threats and applies as much braking pressure as necessary.

Out Of The Blue, DARPA Seeks Means To Manipulate Lightning
From Popular Science:
China and Russia try to control rain clouds and the Dutch use technology to keep low-lying inland areas from flooding, so why shouldn’t the United States be able to manipulate lightning? In an attempt to better understand one of nature’s most powerful processes, DARPA issued a broad agency announcement yesterday asking for ideas on how to best protect American personnel and resources from dangers and costs associated with lightning strikes.

How Book Publishers Could Clobber Amazon
Walk into your local bookstore, and all is peace and order. But the tranquility masks an industry on fire. The traditional book business is being burned to the ground by technology, by recession, by the Internet -- but mostly by Amazon.
Amazon is the best thing that ever happened to self-published authors. They offer a complete publishing service that includes editing, design, and distribution -- even into brick-and-mortar bookstores. Meanwhile, they're getting ready to dictate terms over the fast-growing eBook market. Traditional publishing is being decimated, and the future looks bleak.

Will Free Wi-Fi Become The Norm?
McDonalds Is Latest Company to Offer Free Wireless Internet; Airlines and Many Hotels Still Charge.
(CBS) I'm a big fan of free Wi-Fi and appreciate it when coffee shops, hotels and other businesses are nice enough to let visitors use their laptops to surf the Web for free. Last year, for example, Starbucks started offering two hours of free service a day for those who purchase and register a Starbucks card.
And soon you'll be able to get Wi-Fi with your French fries when McDonalds rolls out its free service in January. The company last week announced that it will drop its $2.95 Wi-Fi fee.

North Magnetic Pole Moving East Due To Core Flux
From National Geographic:
Earth's north magnetic pole is racing toward Russia at almost 40 miles (64 kilometers) a year due to magnetic changes in the planet's core, new research says.
The core is too deep for scientists to directly detect its magnetic field. But researchers can infer the field's movements by tracking how Earth's magnetic field has been changing at the surface and in space.

How Tech Touched The '00s
I've been enjoying all of the end-of-decade lists that have suddenly cropped up. I like knowing what I was intimately aware of and what I completely missed.
This week, the Associated Press came out with its list of "50 things that changed our lives in the aughts." First off, the reference to the "aughts" made me chuckle. Back in late 1999, I was concerned about two things: Y2K and what the heck we were going to call the first decade. Neither of those concerns turned out to be much of a problem in the end. "Aughts" certainly never caught on.
Dec. 24, 1968: Christmas Eve Greetings From Lunar Orbit
From This Day In Tech:
1968: The crew of Apollo 8 delivers a live, televised Christmas Eve broadcast after becoming the first humans to orbit another space body.
Frank Borman, Jim Lovell and William Anders made their now-celebrated broadcast after entering lunar orbit on Christmas Eve, which might help explain the heavy religious content of the message. After announcing the arrival of lunar sunrise, each astronaut read from the Book of Genesis.

From Popular Science:
The battery could power zero-emissions homes.
Bringing power storage to the people, Panasonic will bring a home-use lithium-ion storage cell to market in fiscal 2011, making it possible for homes to store a week's worth of electricity for later use. Panasonic -- along with the recently acquired Sanyo -- have already test-manufactured such a battery, which could allow for more widespread deployment of eco-friendly but inconsistent modes of power generation.

High-Tech Cars Are Trouble For Some Mechanics
From MSNBC/AP:
Automakers hold onto information, bill in Congress would address problem.
LOS ANGELES - A sign inside the Humming Motors auto repair shop says, "We do the worrying so you don't have to."
These days, owner David Baur spends a lot of time worrying in his full-service garage near downtown Los Angeles.
As cars become vastly more complicated than models made just a few years ago, Baur is often turning down jobs and referring customers to auto dealer shops. Like many other independent mechanics, he does not have the thousands of dollars to purchase the online manuals and specialized tools needed to fix the computer-controlled machines.
