Inside One Of The World's Largest Data Centers


From CNET:

CHICAGO--On the outside, Microsoft's massive new data center resembles the other buildings in the industrial area.

Even the inside of the building doesn't look like that much. The ground floor looks like a large indoor parking lot filled with a few parked trailers.

It's what's inside those trailers, though, that is the key to Microsoft's cloud-computing efforts. Each of the shipping containers in the Chicago data center houses anywhere from 1,800 to 2,500 servers, each of which can be serving up e-mail, managing instant messages, or running applications for Microsoft's soon-to-be-launched cloud-based operating system--Windows Azure.

Web Could Run Out Of Addresses Next Year, Warn Web Experts

We could run out of web addresses in the next two years, unless businesses and government organisations heed the advice of the European Commission Photo: GETTY

From The Telegraph:

Businesses urgently need to upgrade to IPv6, a new version of the internet's addressing protocol that will hugely increase the number of available addresses.

A survey, conducted by the European Commission, found that few companies are prepared for the switch from the current naming protocol, IPv4, to the new regime, IPv6. Web experts have warned that we could run out of internet addresses within the next two years unless more companies migrate to the new platform.

From Boston.com:

One Cambridge company has built its success on Kindle. But can it stave off competitors and make good on its vision of revolutionizing everything from credit cards to clothing?

The hottest technology company in the Boston area sits in a low-slung 100-year-old converted factory in the West Cambridge Industrial Park, not far from the Concord Avenue rotary. Inside its modest lobby hangs a 2-by-4-foot display. Messages scroll across it: “Welcome to E-Ink . . . the time is now 2:58 p.m. ’’ It’s 30 minutes slow.

Blue Energy Seems Feasible And Offers Considerable Benefits


From Science Daily:


Science Daily (Nov. 2, 2009) — Generating energy on a large scale by mixing salt and fresh water is both technically possible and practical. The worldwide potential for this clean form of energy -- 'blue energy' or 'blue electricity' -- is enormous. However, it will be necessary to work actively on several essential technological developments and to invest heavily in large-scale trials.

'Breaking' Curveballs Are Just an Illusion

Zhong-Lin Lu, a professor of cognitive neuroscience at USC, who along with USC alumni Emily Knight and Robert Ennis, and Arthur Shapiro, associate professor of psychology at American University, developed a simple visual demo that suggests a curveball's break is, at least in part, a trick of the eye.

From Live Science:

The answer to the question of whose curveball breaks harder — that of the Yankees' A.J. Burnett or the Phillies' Cole Hamels — may be neither. Zhong-Lin Lu, professor of cognitive neuroscience at USC, along with colleagues from USC and American University, developed a simple visual demo that suggests a curveball's break is, at least in part, a trick of the eye. Their demo won the Best Visual Illusion of the Year prize at the Vision Sciences meeting earlier this year. Try it here. A related press release is here. The curveball's effect is due to batters being forced to switch between peripheral vision and central vision during a swing. For more on the research, see Lu's Web page. For more on Lu, read his responses to the ScienceLives 10 Questions below.

'Fear Detector' Being Developed That Will Be Able To Sniff Out Terrorists

Photo: Security: Checkpoints could one day use 'fear detectors' if a research project is successful.

From The Daily Mail:

A device that smells human fear is being developed by British scientists and could soon be sniffing out anxious terrorists.

The technology relies on recognising a pheromone - or scent signal - produced in sweat when a person is scared.

Researchers hope the 'fear detector' will make it possible to identify individuals at check points who are up to no good.

Terrorists with murder in mind, drug smugglers, or criminals on the run are likely to be very fearful of being discovered.

Getting Beyond Petroleum Won't Be Easy

From Technology Review:

Transportation defines our civilization. Where we live and work, the structure of our cities, the flow of global commerce--all have been shaped by transportation technologies. But modern transportation's reliance on fossil fuels cannot be sustained. Passenger planes, trains, and automobiles were responsible for nearly four billion tons of carbon dioxide emissions in 2005--about 14 percent of the carbon dioxide emitted globally that year. If we continue to rely almost exclusively on petroleum to power these vehicles, they will be responsible for 11 billion to 18 billion tons of carbon dioxide emissions in 2050. That's because developing nations--which are home to 82 percent of the world's population and will be responsible for 98 percent of population growth in coming years--are on the verge of mass motorization. Auto ownership in the developing world is growing at a rate of 30 percent per year (see "Cleaner Vehicles by the Million").

From Technology Review:

Coatings and composites ease the air-traffic worries dogging wind power.

Last month Danish wind turbine company Vestas and U.K. defense contractor QinetiQ demonstrated the first "stealth" wind-turbine blade--their solution to the aviation radar interference problem holding up the installation of gigawatts-worth of proposed wind farms worldwide. Vestas composites specialist Steve Appleton says the firm is eager to test a complete stealth turbine and begin limited production by the end of 2010. "Clearly this technology, if proven fully and then adopted by Vestas, would give us a competitive advantage," says Appleton.

File-Sharers Are Big Spenders Too

From The BBC:

People who download music illegally also spend an average of £77 a year buying it legitimately, a survey has found.

Those who claimed not to use peer-to-peer filesharing sites such as The Pirate Bay spent a yearly average of just £44.

Almost one in 10 of those questioned aged between 16 and 50 said they downloaded music illegally.

However, eight out of 10 of that group also bought CDs, vinyl and as MP3s.

From New Scientist:

AS MEDIEVAL CASTLE bedrooms go, this one looks the part. Disturbing Flemish tapestries share the walls with stern portraits. On close inspection, the ornate fireplace's iron firedogs turn out to have devils' heads. This place is supposedly haunted by the ghost of Tom Skelton, a 16th-century jester said to have committed murder. The malevolent face of "Tom Fool" stares from a dimly lit oil painting just outside the bedroom.

From Live Science:

Mass extinctions that wiped entire species off the face of the Earth in a relative blink of the eye are often blamed on catastrophic occurrences, such as an asteroid crash or large volcanic eruption. But a new hypothesis points to a different culprit: lowly algae.

In the past 540 million years, five massive extinctions are thought to have killed off, in each case, some 50 percent to 90 percent of animal species. A new study suggests that toxins from algae played a major role in all five extinctions, including the most recent and most well-known – the death of the dinosaurs 65 million years ago. The idea was presented at the annual Geological Society of America meeting Oct. 19.

Is Hydrogen The Future? This Car Goes 0 To 60 In 12 Seconds.

From Christian Science Monitor:

US Energy Secretary Steven Chu has said that hydrogen-fueled cars will not be pratical for a decade. But researchers at Hyundai-Kia Motors in South Korea say they're on course to make them in six years.

Yongin, South Korea - When the US government cut funding for hydrogen-fueled cars last May, Energy Secretary Steven Chu said such vehicles will not be practical for another decade or two.

Lim Tae-won thinks he can prove Secretary Chu wrong.

Dr. Lim runs the team at Hyundai-Kia Motors that is developing hydrogen fuel cell technology. And they are on course, he says, to mass produce hydrogen cars in six years.
