Sony unveils PS4 console

Sony provided the world the first look at its new PlayStation 4 console, promising to combine its film, music, television and game strengths in a powerhouse home entertainment box.

Sony Computer Entertainment president Andrew House touted the next-generation videogame consoles as being built for the future while, at the same time, saying the company was remaining true to the new console's predecessor, the PlayStation 3.

"This is a completely new platform and, in many ways, represents a completely new PlayStation," House said during a press event here on the eve of the premier E3 videogame expo.

We are more than ever capitalizing on the vast network of Sony divisions and the reputation of one of the biggest and most powerful entertainment brands in the world.

The PS4 will launch with beefed up offerings at the Sony Unlimited movie and music services as the console moves to expand into a complete home entertainment center while remaining true to hardcore gamers.

As Sony sets out to win fans for the PS4, it will continue to ramp up content for PS3.

First Apple computer auctioned

Breker claims it is one of only six known remaining functioning models in the world. Breker already sold one last year for 4,92,000 euros.(Getty Images)

The Apple II was a single-board computer like the Apple I, but the Apple II was much improved, going several steps further than its predecessor. The Apple II had the BASIC (Beginner's All Symbolic Instruction Code) programming language built in, and it had the ability to display text and graphics in colour.

TIANHE beat IBM - China develops fastest supercomputer

Chinese scientists have once again built the world''s fastest supercomputer, capable of performing 33.86 quadrillion operations per second, surpassing the US Titan supercomputer.

Chinese scientists have once again built the world''s fastest supercomputer, capable of performing 33.86 quadrillion operations per second, surpassing the US Titan supercomputer.

The Tianhe-2, or Milkyway-2, has a peak performance speed of 54.9 quadrillion operations per second, according to the National University of Defense Technology (NUDT), which built the computer.

This is the second time China has made it to the first place in the Top 500 list of the world''s most powerful supercomputers.

Tianhe-2''s predecessor, Tianhe-1A, was the world''s fastest supercomputer from November 2010 to June 2011, when it was surpassed by Japan''s K computer.

Matching home-grown Feiteng-1500 CPUs as well as Intel Xeon and Xeon Phi processors, Tianhe-2 was almost twice as fast as the second computer, Titan, which is capable of running at 17.6 quadrillion operations per second.

Sequoia, another US-developed supercomputer, ranked third in the list, followed by Japan''s K computer.

Costing 100 million US dollars, Tianhe-2 is expected to be operational at the supercomputer center in Guangzhou City in south China''s Guangdong Province later this year. "Ranking is not so important," said Li Nan, spokesman of the Tianhe-2 project.

We are producing supercomputers with a fundamental purpose of providing a driving force for the construction of an innovation-oriented country and solutions to sciences that concern the future development of human beings.

Experts believed Tianhe-2 demonstrates that China has been developing its own chip technology, which will ensure that the country plays an important role in the world''s high-performance computing (HPC).

Jack Dongarra, one of the editors of Top 500, said he was impressed with Tianhe-2''s interconnect, operating system and software which are mainly Chinese. "The HPC development has enhanced China''s competitiveness," he said.

Rajeeb Hazra, Intel''s vice president, said the production of Tianhe-2 will not only benefit Chinese sciences and industries, but also provide sound infrastructure for the growing global demands of big data processing.

The NUDT said it would produce a supercomputer performing 100 quadrillion operations per second by 2015 and further raise it by 10 times around 2020.
