World's biggest computer built for US nuclear department

The US government is building a supercomputer for its nuclear department that will be the most powerful computer in the world.

The computer will be used by the Department of Energy's National Nuclear Security Administration (NNSA) and will be ten times faster than today's most powerful system.

Two systems will be built for the super-computer by IBM. The first is Sequoia, a 20 petaFLOP/s (quadrillion floating operations per second) system based on future BlueGene technology. This will be delivered starting in 2011 and deployed in 2012. The second is an initial delivery system called Dawn, a 500 teraFLOP/s (trillion floating operations per second) BlueGene/P system, being delivered in the first quarter of 2009. Dawn will lay the applications foundation for multi-petaFLOP/s computing on Sequoia.

To put the size of the computer into perspective, if each of the 6.7 billion people on earth had a hand calculator and worked together on a calculation 24 hours a day, 365 days a year, it would take 320 years to do what Sequoia will do in one hour.

NNSA administrator Thomas D'Agostino said, "These powerful machines will provide NNSA with the capabilities needed to resolve time-urgent and complex scientific problems, ensuring the viability of the nation's nuclear deterrent into the future. This endeavour will also help maintain US leadership in high performance computing and promote scientific discovery."

The most expensive laptop

In 1982 GriD Systems released the Compass 1100 laptop costing about $10,000 (inflation adjusted $20,200). Even this cost pales in comparison to the reports of a costly laptop that luxury manufacturer Luvaglio London is set to release in the near future by special order the most expensive laptop ever sold, with a price tag of a million dollars.

As of now all of the details are very sparse and the technical specifications have not been made fully available. We aren’t even sure what this laptop is made with to give it a cost of $1,000,000, but the exterior looks impressive. You can bet with a price this excessive, the expensive laptop will be a spectacle of precious metals and materials and include more than a couple gemstones.

In late 2005 the Dutch company Ego Lifestyle B.V. released the Tulip E-Go Diamond laptop, which was previously the world’s most expensive laptop and this mobile computer had over 80 total carats of diamonds and a retail price of €283,000.

the advantage and disadvantage using facebook:)

Facebook - a popular name among those who are so into it. Individuals who have an account in Facebook are now using more of their time to socialize with other people amidst the distance and lack of time. And even if a community like Facebook serves numerous advantages, it also proves to have certain disadvantages as well. There are now series of improvements in the system just to make up with the shortcomings. Arguments regarding the different advantages and disadvantages of Facebook are stated below.

Advantages 
· Allows user search for new and old friends
· Accessible to chosen universities having a high level of security
· Makes it less awkward when communicating with strangers or people you are not familiar with
· Love attraction - can be used as a dating service system
· Makes it easier to join groups having similar likes and dislikes
· Allows members to check students who are taking the same class, living within the same area, or coming from the same academy

Disadvantages
· Overcrowding
· Weakening long distance relationship
· Unsupported by physical adjacency
· Contributes wide-range procrastination
· Rampant addiction
· Stalking is possible
· Acquaintances be labeled as friends

Surely, the disadvantages don't pose a threat to you just by merely looking at it. Someone else has to prove that what users do with their profile is directly in proportion with what can happen to them. A user must understand what he is trying to give out otherwise things might get messy and people will mistook them as someone else.

Hope you enjoy it :D
