VidoopCAPTCHA – is this a joke?
If you follow me on Twitter, you know I HATE CAPTCHAs. I’ve sworn never to use them for years now. I guess it falls in line with my politics – I refuse to treat all commenters like spammers. I use Askimet here, and even it eats legitimate comments once in a while. But at least it’s invisible to users – no need to make everyone pass a Turing Test to do anything.
Vidoop’s new CAPTCHA system, pictured above, is atrocious. They advertise it as “computer proof but not human proof.” It stands as a perfect example of what I hate: increasingly difficult hoops for customers to jump through to use a product or service. I get a headache just thinking about the possibility that one day I might have to take tests like this one every single time I sign-up to try a new web service, participate in an online discussion, or even leave feedback or ask for support from a service I pay for.
Even if it turns out to be easier than deciphering and correctly typing blurry numbers and letters, I worry that it may in fact be, on occasion, human proof.
Let’s look at their demo. Which ones is “castles”? It must be S, even though that doesn’t look like a castle to me. In this case, there’s nothing else that seems to qualify so it should work out. But assuming they’re putting one of their best examples forward as a demo, what do their less-than-best ones look like? Is there really no chance that sometimes it might be a little confusing which picture they want? Especially for people who aren’t native English speakers.
Designers & developers: your job is to decrease the number of annoyances in people’s lives, not increase them. Your job is not to keep spammers out, it’s to keep customers in.
Parts of Flint may go feral
Property abandonment is getting so bad in Flint that some in government are talking about an extreme measure that was once unthinkable — shutting down portions of the city, officially abandoning them and cutting off police and fire service.
Temporary Mayor Michael Brown made the off-the-cuff suggestion Friday in response to a question at a Rotary Club of Flint luncheon about the thousands of empty houses in Flint.
Brown said that as more people abandon homes, eating away at the city’s tax base and creating more blight, the city might need to examine “shutting down quadrants of the city where we (wouldn’t) provide services.” [...]
City Council President Jim Ananich said the idea has been on his radar for years.
The city is getting smaller and should downsize its services accordingly by asking people to leave sparsely populated areas, he said.

Artists, Foreclosures and the Ruins of the Unsustainable
Although it is small consolation in the face of overwhelming economic strife in Detroit and elsewhere as the foreclosure crisis continues, this story gave me a real feeling of hope and renewal. To me, this example and other corresponding cases – like the artist-driven re-imaginings of shopping malls and big box stores seems symbolic of an even larger cultural shift. The arts community isn’t just moving into one downtrodden urban neighborhood; rather, they’re taking on the ruins of the unsustainable. They’re taking on big box stores, shopping malls, and grid-connected homes in the car capitol of North America. And they’re not just creating new art. They’re seizing the opportunity to turn old shells of buildings into independent, renewable energy-powered, 21st century-ready spaces.
What I’m most eager to hear next is that creative pioneers are conquering McMansions in the suburban hintersprawl. As Bryan Walsh wrote recently for Time Magazine, “The Metropolitan Institute at Virginia Tech predicts that by 2025 there will be a surplus of 22 million large-lot homes (on one-sixth of an acre [675 sq m] or more) in the U.S.”
Will subdivisions be turned into workshops and performance spaces? Or possibly into small-scale agricultural communities, or enclaves for artisan food-production? At the very least, will they become denser, transit-connected and less car-dependent … and what will drive that?

Sustainable Industry: Retraining America’s Workforce
In the energy sector, utilities are especially struggling to lure young people to an industry that’s plagued with a somewhat outdated stigma. Peter Darbee, CEO of San Francisco-based Pacific Gas and Electric (NYSE: PCG) in January 2008 told the San Francisco Chronicle that within five years more than 40 percent of the utility’s 20,000 employees will be eligible for retirement. Almost half the nation’s utility workforce will be nearing retirement age by 2016, according to the U.S. Labor Department.
Overall, job seekers with college or technical training will have the best shot at filling utility positions. Computer systems analysts and data analysts are expected to be among the most in-demand workers, in addition to employees with the training to help utilities expand their renewable energy portfolios, according to the Labor Department.
When it comes to training a workforce for a rapidly changing economy, the country’s nearly 1,200 community colleges are at the center of it all. PG&E has even partnered with community colleges to develop its PowerPathway program to train future employees.
With shorter programs and lower tuitions—about $2,360 on average nationwide—than four-year schools, community colleges present fewer barriers to entry for students than private technical colleges or even big, state universities. Plus, many technical and career programs are designed to train and certify workers for in-demand fields in less than a year compared to conventional four-year degree programs.

Was the Tunguska Fireball a Comet Chemical Bomb?
Over a century ago, on June 30th, 1908 a huge explosion detonated over an unpopulated region of Russia called Tunguska. It is probably one of the most enduring mysteries of this planet. What could cause such a huge explosion in the atmosphere, with the energy of a thousand Hiroshima atomic bombs, flattening a forest the area of Luxembourg and yet leaving no crater? It is little wonder that the Tunguska event has become great material for science fiction writers; how could such a huge blast, that shook the Earth’s magnetic field and lit up the Northern Hemisphere skies for three days leave no crater and just a bunch of flattened, scorched trees?
Although there are many theories as to how the Tunguska event may have unfolded, scientists are still divided over what kind of object could have hit the Earth from space. Now a Russian scientist believes he has uncovered the best answer yet. The Earth was glanced by a large comet, that skipped off the upper atmosphere, dropping a chunk of comet material as it did so. As the comet chunk heated up as it dropped through the atmosphere, the material, packed with volatile chemicals, exploded as the biggest chemical explosion mankind had ever seen…
