Sorting Algorithm Explained with a Hungarian Folk Dance

[youtube]http://www.youtube.com/watch?v=lyZQPjUT5B4&feature=player_embedded[/youtube]

Sapientia University has created a series of online videos that illustrate different sorting algorithms using folk dances:

What you have to do is just check that they are in fact implementing the algorithm correctly. The dancers have numbers stuck on their front and they do seem to look down and examine the value on another dancer before performing the dance routine dictated by the algorithm…

Swedish File Sharers Get Religious About Stealing

Praise God and Pass the Torrent?

Swedish philosophy student Isaac Gerson thinks that file sharing is sacred. The 19-year-old leader of the Missionary Church of Kopimism believes that stealing and sharing are signs of appreciation, and has compared closed-source software to slavery. Last year, Sweden rejected the church’s application to be recognized as a religion, but Gerson isn’t giving up so easily…

What’s Your Dominant Eye?

eye 883-023

Which way do you see?

Ocular dominance, sometimes called eye dominance, is the tendency to prefer visual input from one eye to the other. In normal binocular vision there is an effect of parallax, and therefore the dominant eye is the one that is primarily relied on for precise positional information. This may be especially important in sports which require aim, such as archery, darts or shooting sports…

Fowndr Offers Private Social Network for Start-Ups

fowndr-blog480 (1)

Look out people of the Internet, there’s another social network on the horizon! But this new network isn’t designed to compete with Facebook, Twitter or MySpace; instead, it’s intended for the people who build these services.

Fowndr, pronounced founder, is a new private network that hopes to offer creators of technology start-ups a place to discuss new projects and share learning, resources and files with other like-minded technologists.

“It’s basically a safe place for entrepreneurs and founders to share ideas, projects and files,” said Stu Green, founder of Fowndr. “The service is designed for people who have been involved in setting up businesses in the past and love new enterprise.”

Geeky and Funny Haircuts

Geeky_Haircuts_2

With the top of head shaved to look like a face and a pair of glasses to disguise, you can probably make some
professors with badeyesight believe that you are listening attentively while you are actually sleeping.

Costumes are so last year. Now the latest way to show that you have a truly geeky head is to have a truly geeky haircut. Some of the haircuts are so cool that you might want to get one for yourself the next day. Some of them are so funny that you can’t help ROLF-ing. But whatever the case is, if you have any of these 17 crazy haircuts, you’ll definitely get people’s attention wherever you go.

Jail: India’s Next Call Center?

Convict Pradeep Deburma (left) and a fellow inmate of Cherlapalli jail operate computers as part of their training.

The next time you get an Indian talking from a call center on your customer service call, don’t get too upset. Instead, have pity as your counterpart may soon be talking from jail!

For a man serving a life sentence for murder, Pradeep Deburma has a slightly unlikely dream: to work in a call centre like hundreds of thousands of other young ambitious Indians. Even more improbably, he has every chance of realising it while still behind bars…

Test Subjects With Electrode Implants Use Mind Control To Move A Cursor

brain movement 34543

What kind of future technology will come from this breakthrough?

As trippy as mind-control still seems to us, we’ve already seen it implemented in everything from wheelchairs to pricey gaming (and car driving!) headsets. But the problem is that they measure brain activity outside the skull — you know, the thing we’ve evolved to shield the murky goings-on in our minds from prying EEG sensors.

Now, though, a team of Washington University researchers appears to have happened upon a more effective — albeit, invasive — approach…

Scientists Develop Zebra Barcode Reader

Now you will be able to know if you see the same zebra twice.

Scientists have developed an image scanning program that can distinguish between individual zebras by their stripes:

When a zebra has been entered into the database and given a StripeCode, the researchers match another picture of the same animal by comparing the StripeStrings of the new and original images. Each image will generate a different set of StripeStrings, but the underlying ratios of black and white should remain similar…

Jousting on Segways

Actually, the Segway would be a fairly sound vehicle for modern jousting, as this commercial for the State of Washington’s lottery illustrates. But buying lottery tickets is probably not a likely route to this most excellent goal…

Training Sharks to Eat Lionfish

sharks-eating-lionfish-500x303

Lionfish need predators to balance out their ecosystem.

Lionfish are pretty, but they belong in the Pacific and Indian Oceans. They lack natural predators in the Caribbean, so lionfish have become quite the invasive species since they escaped from aquariums ten years ago to breed in the waters off the US and Central America. In Honduras, divers are not only hunting them, they are also training sharks to eat the lionfish!
