K, built by Fujitsu and located at the Riken Advanced Institute for Computational Science in Kobe, Japan, represents a giant leap forward in computing speed.This computer is three times faster than its Chinese rival that previously held the top position, a New York Times report said.

"It's a very impressive machine. It's a lot more powerful than the other computers," the Times report quoted Jack Dongarra, a professor of electrical engineering and computer science at the University of Tennessee at Knoxville who keeps the official rankings of computer performance, as saying.

K pushed back the previous number one, Tianhe-1A supercomputer, at the National Supercomputing Centre in Tianjin, China, to second place. Tianhe-1A was the first Chinese computer to be ranked on top.

The latest ranking of the top 500 computers released Monday, is determined by running a standard mathematical equation. The winning computer was able to make 8.2 quadrillion calculations per second, or 8.2 petaflops per second, the report said.

K is made up of 672 cabinets filled with system boards. Although considered energy-efficient, it still uses enough electricity to power nearly 10,000 homes at a cost of around $10 million annually, Dongarra said.

The fastest computer in the United States, at Oak Ridge National Laboratory was placed third.

In the top 10 list, US computers bagged five places. All of them are in government research facilities, the report said.

Supercomputers are used for earthquake simulations, climate modelling, nuclear research and weapons development and testing. Businesses also use the machines for oil exploration and rapid stock trading.

Amenbo  - The five fingered mouse

If you are one of those who love unusual gadgets, the five fingered mouse would not fail to grip your attention. Named Amenbo by Double Research and Development Company, this device is quite dramatic and interesting. With a device fixed for resting the palm along with five mice fixed with wire ribbons for fingers, you would enjoy working on your laptop/computer now. The interesting device is not just a candy for eyes but also provides comfort to the user.
Apart from comfort, Amenbo offers comfortable time at the 3D space which is missing with the regular mouse with limited 2D functionality. The company claims this mouse to be apt for gamers. This unusual mouse not just has smart 3D image recognition mechanism but also ability of sensing the finger pressures due to sensors fitted in all its finger panels. The mechanism is not that of a touchscreen but the device identifies user’s fingers being a part of his hand and tracks the movements with ease. Manipulation of CAD data and 3D models is the USP of Amenbo. You do not have to attach 3D and ordinary mouse for working on CAD data, Amenbo takes care of it. The mouse packages the dual functions for the convenience of users.

The company is not just offering bizarre mouse to the users, it also claims that it might use the technology in its production of Robotics. The company plans to use the five fingers Amenbo technology for their robots. The regular robots are being operated from either two or three fingers but the company would allow the users to use the five fingers while operating the robot’s hand. This Japanese company is surely leaving no stone unturned to create a benchmark in the world of technology.

When Steve Jobs was born February 24, 1955, in San Francisco, California , his unwed mother decided to put him for adoption because she wanted a girl. So in the middle of the night, his mother called a lawyer named Paul Jobs and said, “We have an unexpected baby boy; do you want him?”

His mother felt very strongly that he should be adopted by college graduates and when she found out that both his future parents had never graduated from colleges, she refused to sign the adoption papers. She only relented a few months later when his future parents promised that they would send Jobs to college.
He went to college but decided to drop out because it was too expensive. Recalling his time there he said,

I didn’t have a dorm room, so I slept on the floor in friends’ rooms, I returned coke bottles for the 5¢ deposits to buy food with, and I would walk the 7 miles across town every Sunday night to get one good meal a week at the Hare Krishna temple.


Jobs and Apple

At 20, he and a friend (Steve Wozniak) started a company in a garage on April 1, 1976. Later that year, the duo debuted the Apple I at the Homebrew Computer Club in Palo Alto, California. A local store offered to buy 50 machines and to finance the production, the duo had to sell their most expensive possesions. Jobs sold his Volkswagen van while Wozniak sold his Hewlett-Packard scientific calculator.


Jobs named their company – Apple in memory of a happy summer he had spent as an orchard worker in Oregon.

By 1982 however, his company sales sagged in the face of competition from IBM’s new PC. Jobs and Wozniak unveiled their new creation, Lisa to increase the company’s bottom line, only to be another expensive failure.

Not wanting to dwell on these successive failures, they worked on a new machine called the Macintosh. Jobs was reported to commandeered the project, ruthlessly pushing its computer engineers and flying a pirate flag above the building where the team worked.

By 1986 the Mac, which Jobs promised to be ‘insanely great’ was a huge success. After 10 years, starting from 2 kids working in a garage, Apple computer had grown into a $2 billion dollar company with over 4000 employees.


At 30 Jobs, however, was fired from the company he co-founded with Steve Wozniak. He left the company after losing a bitter battle over control with Apple’s CEO John Sculley (whom Jobs had recruited from Pepsi Cola).



After Apple 

Apparently both have different views of how the company should be handled and in one meeting Sculley had told security analysts in a meeting that Jobs would have no role in the operations of the company “now or in the future.” When Jobs heard of the message he said, “You’ve probably had somebody punch you in the stomach and it knocks the wind out you and you cannot breathe. The harder you try to breathe, the more you cannot breathe. And you know that the only thing you can do is just relax so you can start breathing again.”


Jobs sold over $20 million of his Apple stock, spent days bicycling along the beach, feeling sad and lost, toured Paris, and journeyed on to Italy.

Recalling this publicly heartbreaking episode Jobs said,
‘I didn’t see it then, but it turned out that getting fired from Apple was the best thing that could have ever happened to me. The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything. It freed me to enter one of the most creative periods of my life.’

During the next five years he started two companies – NeXTStep and Pixar.
NeXTStep which produces NeXT, $9,995 cube-shaped workstation which aimed to create a workstation for research and higher, didn’t do as well as Jobs had dreamed for. It did poorly and Jobs pulled the plug in 1993.

Pixar, however was a success story. The company started the first computer-animated film, the Toy Story and when Pixar’s stock went public, Jobs became an instant billionaire.


Jobs, back with a vengence

Meanwhile, his old company, Apple was under immense pressure from rival Microsoft and in 1996 posted billions of dollars in losses.



In December 1996 Jobs convinced Apple to buy NeXT and make its software the foundation of the next-generation Mac OS. The technology he developed at NeXT became the catalyst of Apple’s comeback. Initially appointed as Apple’s adviser, Steve Jobs was named Apple’s interim CEO in 1997.



In 2004 he was diagnosed with cancer on his pancreas. Jobs was told that the cancer was incurable and he would only live for another three to six months. Later, a biopsy showed that he actually had a very rare form of pancreatic cancer that is curable with surgery. He had the surgery and survives.

Under his leadership, Apple returned to profitability and introduced innovations such as the iPod.
