"Imagine sitting in a cofee house with your laptop and chatting with your dear friend.....and then calling a friend on your phone and then paying your bill and moving out for ur regular work"
1. Now imagine some thing u never imagined.....all what you chatted and all what you spoke on phone in the cafe house is compromised....all saved at a location unknown to you....
2. Two security professionals proved as much at the Black Hat cybersecurity convention in Las Vegas.This has been made possible after investing a few thousand bucks, a tool box and some technical skill like these two security professionals,Richard Perkins and Mike Tassey have done.These two guys have assembled a small, unmanned airplane that is capable of some truly remarkable and potentially disastrous hacks.
3. Perkins is a security engineer supporting the U.S. government and Tassey is a security consultant for Wall Street firms. But after work, the long-time buddies would take off their cyber attack prevention hats, put on their evil hacker thinking caps, and build their airplane in Perkins' garage.
4. The plane can wreak lots of havoc.
- For instance, it can fly over a Starbucks (SBUX, Fortune 500) and steal the personal information of everyone connected to the coffee shop's free Wi-Fi network. It can intercept your cell phone conversations and even reroute your calls to another number. It can trace the location of specific people and follow them home.
- Perkins and Tassey spent a total of just $6,190 to build the plane. They made a point to keep it relatively cheap and to buy components that were readily available to prove that literally anyone could make one."You don't need a Ph.D. from MIT to do this," said Perkins. "There are no custom parts, it was fabricated using hand tools, and very little coding is required. All you need is dedicated people."

1. A one-atom-thick layer of carbon has currently become the focus of interest of IBM and the U.S. military to build computers that function at near the speed of light.
2. The focus is actually based on GRAPHENE, the thinnest and toughest material ever produced, that conducts electricity, a breakthrough that opens the door to its use in digital electronics
3. Some key finding on GRAPHINE :
- Graphene is the basic structural element of some carbon allotropes including graphite, charcoal, carbon nanotubes and fullerenes.
- Graphene conducts electricity 30 times faster than silicon -- approaching the speed of light
- Until recently, use of graphene was limited to development of more-efficient batteries and foldable touch screens.
- Nokia, the world’s largest maker of mobile phones by volume, is investigating the material’s potential use in cell phones, touch screens, and printed electronics.
- Graphene’s flexibility and strength is astonishingly 300 times tougher than steel - may lead to the Nokia Morph, the first foldable phone.
- “With a graphene battery the same amount of weight and volume as a current one, you could drive 300 miles instead of 100,” said Yuegang Zhang, a principal investigator at the lab.
- Graphene has the ideal properties to be an excellent component of integrated circuits. Graphene has a high carrier mobility, as well as low noise, allowing it to be used as the channel in a FET.

1. On way to experiment with android application with the stand SDK toolkit....i got messed up with the installation procedure so much that i thought of just leaving it..... in spite of all java installed i got this screen.....
2. I read all trouble shoots of on JAVA site.....some diverted me to registry editors and what not.......till i got the correct answer...simply click BACK and then NEXT again......khatam...thats the end of it.....
