Egyptian Entrepreneurs Hope Technology, Google Funding, Will Spur Economy

The Egyptian revolution sent the country’s economy into a tailspin. Egypt was already plagued by high unemployment, particularly among those under the age of 30. Amid ongoing unrest, foreign investors have put projects on hold. Once-reliable industries like tourism are struggling. But several dozen technology entrepreneurs think they have what it takes to spur job creation, despite political uncertainty. They are taking part in a competition sponsored by Google, which will award a $200,000 prize to one business.

In a conference room at the elegant Fairmont Hotel in Cairo, two young men are playing a fierce game of table tennis. Around them, youthful entrepreneurs slouch in bean bag chairs, pecking furiously at their laptops. Hundreds of Egyptians are jammed into small booths around the perimeter of the room. Each one is ready to explain how his or her tech business has the potential to be the next big thing.

"With IntaFeen,you can share your location with friends and family on the go. Whether you are in a restaurant, watching a movie, eating ice cream, in a park, you share this information with your friends and family," said Adel Youssef, the founder and CEO (chief executive officer) of Wireless Stars. He said spent five years working in the United States but moved back to Egypt because he saw unexploited opportunity. He and his team have created a mobile application called IntaFeen. It’s a location-based social network. Users write reviews of restaurants and movies.

They earn “badges” for places where they check in frequently. Youssef says the idea is based on the popular “Foursquare” application, but has a different cultural sensibility. "If you see the badges of Foursquare they are designed for U.S. culture or West culture. My favorite badge is gym rat. A gym rat in the U.S. is someone who is actively working in the gym. If you see someone here and you give him this badge, that is insulting," he said.

About 110,000 people from Egypt to Ghana to Pakistan have downloaded the IntaFeen app.

Organizers say the point of the competition is not just for Egypt’s young techies to show off, but to address one of Egypt’s most pressing problems: unemployment. Egypt’s official unemployment rate is 12-point-4 percent, but many believe it to be much higher. Around 90 percent of the unemployed are young, under the age of 30. But can tech companies really create jobs?

Maha Elbouennein, the head of communications for Google in the Middle East and North Africa, said "These are 50 companies that didn't exist six months ago. In order to be participating in the program, they have to be registered, legal entities. This isn't a business plan competition. So the evidence in itself, that 50 companies exist today that didn't six months ago is evidence enough about how it’s helping the economy and it’s growing. It’s creating jobs."

Elbouennein says, of course, Google has its own financial interests in the region. "Google basically wants people to live on the Internet," he said.

If technology businesses get bigger in Egypt, inevitably, so will Google.

Some of the entrepreneurs have set their sights beyond North Africa and the Middle East. Yasmin Elayat is the CEO of Groupstream, a storytelling platform that lets users interact with one another by adding photos, tweets and blog posts into an online “stream.” Groupstream is going to launch in the United States, first. "The idea started when we noticed that during the Egyptian revolution, Egyptians were documenting our country’s history in real time on social media and Facebook and Twitter and on photos and videos on cell phones and cameras," she said.

Elayat turned that initial spark of an idea into a crowd-sourced documentary project called 18 Days in Egypt. But she says she soon realized that the same technology could be useful for those who did not have anything quite so dramatic as a revolution to document. "It doesn't even have to be news. I see my cousin, she’s like 11 and her whole life is on social media. She doesn't even know what it feels like to hold a photograph anymore," she said.

Google has narrowed a list of 4,000 entrants down to 20 businesses and will pick a winner in May. But win or lose, many of the entrepreneurs share the same hope: that Egypt’s youth, which have been at the forefront of so much political change and upheaval in the last year-and-a-half might now become the leaders of a technological revolution.

Now, robotic jellyfish powered by hydrogen

Researchers at Virgina Tech have created a hydrogen-powered robotic jellyfish, named Robojelly, which could be used in underwater search and rescue operations.
Being fuelled by hydrogen also means that it could never run out of energy.
Constructed from a set of smart materials, which have the ability to change shape or size as a result of a stimulus, and carbon nanotubes, Robojelly is able to mimic the natural movements of a jellyfish when placed in a water tank and is powered by chemical reactions taking place on its surface.
“To our knowledge, this is the first successful powering of an underwater robot using external hydrogen as a fuel source,” said lead author of the study Yonas Tadesse.
The jellyfish is an ideal invertebrate to base the vehicle on due to its simple swimming action: it has two prominent mechanisms known as “rowing” and “jetting”.
A jellyfish’s movement is down to circular muscles located on the inside of the bell – the main part of the body shaped like the top of an umbrella. As the muscles contract, the bell closes in on itself and ejects water to propel the jellyfish forward. After contracting, the bell relaxes and regains its original shape.
This was replicated in the vehicle using commercially available shape memory alloys (SMA) – smart materials that “remember” their original shape – wrapped in carbon nanotubes and coated with a platinum black powder.
The robot is powered by heat-producing chemical reactions between the oxygen and hydrogen in water and the platinum on its surface. The heat given off by these reactions is transferred to the artificial muscles of the robot, causing them to transform into different shapes.
This green, renewable element means Robojelly can regenerate fuel from its natural surroundings and therefore doesn’t require an external power source or the constant replacement of batteries.
At the moment, the hydrogen-powered Robojelly has been functioning whilst being clamped down in a water tank. The researchers admit that the robot still needs development to achieve full functionality.
“The current design allows the jellyfish to flex its eight bell segments, each operated by a fuel-powered SMA module. This should be sufficient for the jellyfish to lift itself up if all the bell segments are actuated,” Tadesse explained.
“We are now researching new ways to deliver the fuel into each segment so that each one can be controlled individually. This should allow the robot to be controlled and moved in different directions,” Tadesse said.

Soon, control robotic planes by simply waving your arms

Researchers have devised a new system that could one day allow drone aircraft taxiing on a runway to recognise and follow hand gestures.
Presently, drones can land autonomously on aircraft carrier decks, but are controlled by humans during taxiing.
With piloted aircraft, navy flight-deck marshals follow a codified set of hand gestures to direct them to, for example, cut their engines, open weapon bay doors or move to a refuelling bay.
To test whether these gestures could be recognised by a computer, Yale Song and colleagues at the Massachusetts Institute of Technology wrote an algorithm that analyses 3-second clips from a depth-sensing camera trained on a person performing flight-deck gestures, the New Scientist reported.
The system recorded body, arm, wrist, hand and finger positions and could consequently identify a flight-deck command with an accuracy of 76 per cent.
The team revealed that it is currently working towards improving recognition levels.
 “I can’t see why this wouldn’t work ultimately,” said Peter van Blyenburgh, head of UVS International, a drone trade group.
“The gestures are clearly defined – an image sensor should be able to pick them up,” Blyenburgh added.
The study will appear in ACM Transactions on Interactive Intelligent Systems.

Google Chrome took lead over Internet Explorer on March 18

http://static.indianexpress.com/m-images/Fri%20Mar%2023%202012,%2011:24%20hrs/M_Id_277198_Google_chrome.jpg
Google Chrome briefly emerged as the world's most popular web browser last weekend, overtaking Microsoft’s Internet Explorer for the first time, according to statistics.
StatCounter, which compiled the figures, said Google Chrome took the lead on March 18, when office workers were using their own computers instead of ones controlled by corporate IT departments.
"While it is only one day, this is a milestone. At weekends, when people are free to choose what browser to use, many of them are selecting Chrome in preference to IE," The Telegraph quoted StatCounter's chief executive Aodhan Cullen, as saying.
According to Statcounter data, Chrome was used for 32.7 per cent of browsing, while Internet Explorer had 32.5 per cent share on March 18.
But Microsoft's share recovered to 35 per cent, while Chrome's share slipped to 30 per cent on March 19.
Chrome relegated Firefox from second to third position worldwide for the long term in December.
Some analysts have questioned whether Google can also overturn Internet Explorer due to Microsoft's dominance of incorporate desktops.
"Whether Chrome can take the lead in the browser wars in the long term remains to be seen, however the trend towards Chrome usage at weekends is undeniable," Cullen said.
StatCounter data is collected from a sample of over 15 billion page views on more than three million websites.

Now, a new theory on size of black holes

Planetary scientists have come up with a new theory on the size of black holes -- claiming some of them have no "table manners", and tip their "food" directly into their mouths, eating more than one course simultaneously.
For its research, a team from the University of Leicester in the UK and Monash University in Australia investigated how some black holes grow so fast that they are billions of times heavier than the sun.
Prof Andrew King at University of Leicester, who led the study, said, "Almost every galaxy has an enormously massive black hole in its centre. Our own galaxy, the Milky Way, has one about four million times heavier than the sun.
"But some galaxies have black holes a thousand times heavier still. We know they grew very quickly after the Big Bang. These hugely massive black holes were already full-grown when the universe was very young, less than a tenth of its present age."
Black holes grow by sucking in gas. This forms a disc around the hole and spirals in, but usually so slowly that the holes could not have grown to these huge masses in the entire age of the universe.
The scientists made a computer simulation of two gas discs orbiting a black hole at different angles. After a short time the discs spread and collide, and large amounts of gas fall into the hole. According to their calculations black holes can grow 1,000 times faster when this happens.
"If two guys ride motorbikes on a Wall of Death and they collide, they lose the centrifugal force holding them to the walls and fall," says King. The same thing happens to the gas in these discs, and it falls in towards the hole.
This may explain how these black holes got so big so fast. "We don't know exactly how gas flows inside galaxies in the early universe but I think it's very promising that if the flows are chaotic it is very easy for the black hole to feed," said King.
The findings are to be published in the 'Monthly Notices of the Royal Astronomical Society'.

TOMTOM VIA 125: Plug & Go

http://static.indianexpress.com/m-images/Thu%20Mar%2029%202012,%2002:49%20hrs/M_Id_278535_TOMTOM_VIA_125.jpg
For your next road trip, don’t leave the house without your car navigation system. With a sophisticated navigation system—in-dash or on top of it— you’ll never have to struggle with confusing maps or unintelligible instructions ever again. It reduces driver stress too. Of course, commuters can’t wish away the traffic jams, but some navigation systems monitor traffic to avoid chaos on the roads. After one car trip with the Dutch manufactured TomTom Via 125 navigation system, I was hooked!
This R18,990-a piece portable navigation device couldn’t be simpler to use—just plug in and tap the touch screen. You will be on your way very quickly with its intuitive user interface. TomTom’s updated maps feature all the monuments, chowks, parks or attractions you need to find your way. Wherever you need to be, search for the nearest landmark and let TomTom show you the route.
Designed for convenience, the device even lets you use your voice for many different tasks, such as entering addresses and making calls hands-free. One can navigate complex junctions with ease using advanced lane guidance. No wonder, driving with these more fuel-efficient routes saves you money as well as reducing your impact on the environment.
Car navigation systems are fast becoming one of the most popular mobile electronics items on the market. Making your journey as convenient as possible, a navigation system features turn-by-turn directions that are both audible and visible, technology that automatically redirects you if you miss a turn, and point-of-interest-mapping in case you need a bite to eat or are looking for the nearest ATM.
I firmly believe that portable navigation devices are must-haves these days, especially if you travel or drive frequently. There is no shortage of navigation devices on the market with prices ranging from the low of R7,000 to as high as R50,000. But buying a direction-giving device that fits your particular needs can be confusing unless you know precisely what to look for.
You may believe that car navigation systems are just a glorified map for those who can’t remember correct road directions. Believe me and I am not exaggerating TomTom Via is so much more than just a map that says, “You are here.” It has a lot of great features that you may not even know about, making it more useful, easier to use or just plain fun. For instance, it clearly shows which lane to take at junctions so you don’t miss your turning. On the most difficult highway intersections, realistic 3D representation of the junction keeps you relaxed and safe.
Normally, car drivers prefer their navigation system to blend in with the dashboard to appear as seamless as possible. The TomTom navigation device sits on top of the dashboard and matches your car and style. And when it comes to screen display, the bigger navigation devices are, the better. Units with bigger screen sizes are easier to use and navigate. TomTom Via has clear display, reflective coating and anti-glare features. It is easier to read on the 5-inch screen in the daytime. Its touchscreen technology gives you the optimum view with the easiest control to make operating your device a pleasure.
Helping you to keep your eyes on the road, spoken instructions on the TomTom Via include street names, to make turnings even clearer. Guidance come available in Indian accented English plus 10 additional regional languages—Hindi, Telugu, Kannada, Tamil, Punjabi, Malayalam, Marathi, Bangla, Gujarati and Oriya. You can choose icons for your most frequent destinations and add your own text. This makes your navigation experience truly your own with even easier and quicker navigation to the places you go most often.
There’s a convenient foldaway mount that’s integrated with your device, so it’s always there when you need it. It attaches easily to your windscreen. And using the optional mounting disk, you can turn it upside down and position it on your dashboard too, where the screen automatically flips to the right way up.
My verdict:
TomTom Via can be a good choice for easygoing navigation on Indian roads.
