Some of the instruments aboard the satellites collect data in different ranges of wavelengths of light. These “spectral bands” break up all the visible and invisible light into chunks: the reds, the blues, the greens and even infrared, a wavelength of light that humans can’t see.
When researchers piece the image data back together, they can be selective about which “bands” of light are displayed in the final image. “The selection depends on the intent of the analysis,” Friedl wrote in an email. “An analysis of vegetation would probably select the red, green and infrared bands — vegetation is ‘bright’ in those bands and the analyst could differentiate between the types or health of vegetation.”
Friedl says analysts generally don’t go out of their way to make images look surreal, but this kind of spectral analysis can be used to great effect. “There are whole books written on what band combinations to use to bring out certain features,” he told me. Like rocks: When studying the retreat of the glaciers of the Himalayas, Friedl says, you can train software to recognize the light signature of exposed rock. And instead of directly measuring the glaciers themselves, you can see where new rock is getting exposed year over year.
With Age Comes Happiness February 20, 2013Posted by tkcollier in Lifestyle.

So why do we tend to think of older people as primarily depressed and unhappy, a perception that seems to be supported by the fact that the elderly have the highest suicide rates, when they themselves often report being happier now than when they were younger — and when studies show well-being rises after mid-life?
One reason for the happiness and suicide rates being at-odds could be related to the fact that happiness ratings often rely on general population figures, not measures of particular individuals, which can be much more varied. As data from several Scandinavian countries shows, it’s possible for a country to lead the world in both population happiness and suicide rates. While the reasons aren’t clear — perhaps the cold, dark winters are difficult to take for some, or perhaps being depressed when everyone around you is happy is even harder to take — the conflicting trends do occur simultaneously.
“It does seem like a paradox, but both happiness and depression can increase with age,” says Sutin. It is possible to swing between the two states and it is also possible that age pushes people to one extreme or another. “With age, people tend to become more emotional and experience both sadness and happiness,” she says. That could account in part for why we tend to see the elderly as sad: the sadness is both more visible and more congruent with our expectations about this stage of life.“
Especially when we’re young, it’s really easy to look at older adults and see the loss: loss of youth, loss of mobility, loss of loved ones,” Sutin says. “We assume that all of that loss would make older adults unhappy. It’s harder to see the benefits of aging: feelings of pride for children and grandchildren, a meaningful career, more confidence, wisdom. There are a lot of reasons to be happy in older adulthood, but they may not be as visible as the losses.” When they are, however, it turns out that happiness is one of the benefits that come with age.
Globalization’s Geopolical Future February 18, 2013Posted by tkcollier in Geopolitics, In The News.

Essay by a prescient Geo-strategist, whose work I follow.
Today’s globalization is suffering a populist blowback on a nearly global scale. Indeed, the only places not suffering such blowback are Latin America, Africa and Southeast Asia, frontiers where globalization’s widespread wealth creation is still resulting in very positive outcomes. Just about everywhere else, whether in the old West, the rising East or the Arab world, we’re seeing a build-up of social anger at globalization’s inequities and excesses that is stunning in its scope and persistence. In short, the world seems destined to either re-balkanize itself over these tensions or enter into a lengthy progressive era that corrects these imbalances and cleans up these corrupting trends.
Here’s where the value of the trans-Atlantic bond comes back in. For, remember, the old West has already processed the very same sort of mega-cycle back at the turn of the 20th century, when the world’s first version of a middle class initially came into its own as a potent political force. In that scary millenarian maelstrom, as today, terrorists, revolutionaries and radical fundamentalists abounded. In the end, both extremes of the ideological spectrum reached their catastrophically evil expression in the form of Stalinist Russia and Nazi Germany.
But not everybody in that old West got it wrong. Indeed, America and, to a lesser extent, Britain got it spectacularly right. Their shared Progressive Era was a classic example of co-evolution, in that both sides of “the pond” fed off each other’s experiments and successes — the women’s suffrage movement, social welfare, modern police departments, sanitation, mass transit, labor reforms, food and drug safety — while learning from their mistakes. But through it all, an economic landscape was substantially re-graded, leveled out, as it were, in a “fair deal” to the workingman that tamed all that raging populist anger. The leadership that was seen during the Progressive Era, embodied by the career of Theodore Roosevelt, is the same sort of leadership that America, and the world, needs today.Getting back to my “C-I-A” world of tomorrow, these three superpowers — two in the making, one actual — are currently in a race to see which can process its own domestic populist rage faster and more effectively.

Rich Blocks, Poor Blocks is an interactive map (created by Christopher Persaud, a data reporter for a bank website) showing the average income for every neighborhood in America. Type in your address, press search, and there you have it: Your city, shaded by income, according to data from an annual survey conducted by the Census Bureau. The greenest blocks–Census blocks, that is, not city blocks–signify the richest areas, typically bringing in an average household income of $100,000 or more a year. The reddest blocks are the poorest, with annual income somewhere around $20,000. All the rest get some shade of red or green, depending where they fall.

Virus writers are having a field day. A new industry has blossomed called Exploit Kits. Talented programmers sell their exploit kits for $3000 a pop to help their brethren malware writers deliver their payloads more effectively.
Late 2012, the NY Times published a controversial piece questioning the effectiveness of modern antivirus software. The shocking conclusion was that after an exhaustive analysis of over 40 antivirus products, there was only a 5% chance of detecting and defeating a new threat. That is, if a computer had 40+ antivirus products running simultaneously, there is a scant 5% chance that the computer would be safe from new threats.
The US Department of Homeland Security advised last week that users disable Java. This is unprecedented. The government felt this is a computing problem so severe that it must intervene. Java is a real and present threat to not only our national security but our computers, privacy and wallets. The DHS has no motivation to sow misinformation or fear, and they should be heeded. (more…)

On May 28, 2008, Adam LeWinter and Director Jeff Orlowski filmed a historic breakup at the Ilulissat Glacier in Western Greenland. The calving event lasted for 75 minutes and the glacier retreated a full mile across a calving face three miles wide. The height of the ice is about 3,000 feet, 300-400 feet above water and the rest below water.
Chasing Ice won the award for Excellence in Cinematography at the 2012 Sundance Film Festival, and has won 24 awards so far this year. Playing in theaters now. Thanks to Valerie Sanders. Click on the YouTube logo, choose the HD option and go Full Screen for the full effect.
Marlin Sinks Boat February 1, 2013Posted by tkcollier in Cool photos, In The News, Sports.

Not all the details are in, but apparently the captain began backing down on the huge fish, a common practice in big-game fishing when a fish is taking line. He puts the boat in reverse to chase the fish.
One commenter on Marlin Magazine’s Facebook post who apparently had some knowledge of the incident said that the captain fell as he was backing down on the fish at full throttle. The boat took on too much water and, finally, there was no correcting the situation. So, indirectly, the fish sank the boat.
Marlin Magazine reported that the boat went to the bottom of the sea and everybody on board was rescued by the photo boat. And, of course, the fish got away. Or as Marlin Magazine put it on its Facebook post, “Marlin Wins!” Thanks Randy Marks
