CLOUD COMPUTING

An emerging IT delivery model—Cloud Computing—can significantly reduce IT costs & complexities while improving workload optimization and service delivery. Cloud computing is massively scalable, provides a superior user experience, and is characterized by new, internet-driven economy.


The much talked about Cloud Computing promises to change the way Information Technology people look at delivering IT and the way people perceive it.

The name Cloud Computing was inspired by the symbol that’s often used to represent the internet in flow charts and diagrams. Cloud Computing is a general term used for anything involves delivering hosted services over the internet. These services are broadly divided into three categories: Infrastructure-as-a-Service and Platform-as-a-Service, Software-as-a-Service. A cloud service has three different characteristics that differentiate it from traditional hosting. It is sold on demand, typically by the minute or the hour it is elastic-a user can have as much or as little of a service as they want at any given time. The service is fully managed by the provider and the consumer needs nothing but a computer and internet access. Significant innovations in virtualizations and distributed computing, improved access to high speed internet and a weak economy, have accelerated interest in Cloud Computing.

ELECTROMAGNETIC BOMB: A WEAPON OF ELECTRONIC MASS DESTRUCTION


The next Pearl Harbor will not announce itself with a searing flash of nuclear light or with the plaintive wails of those dying of Ebola or its genetically engineered twin. You will hear a sharp crack in the distance. By the time you mistakenly identify this sound as an innocent clap of thunder, the civilized world will have become unhinged.

Fluorescent lights and television sets will glow eerily bright, despite being turned off. The aroma of ozone mixed with smoldering plastic will seep from outlet covers as electric wires arc and telephone lines melt. Your Palm Pilot and MP3 player will feel warm to the touch, their batteries overloaded.

Your computer, and every bit of data on it, will be toast. And then you will notice that the world sounds different too. The background music of civilization, the whirl of internal-combustion engines, will have stopped. Save a few diesels, engines will never start again. You, however, will remain unharmed, as you find yourself thrust backward 200 years, to a time when electricity meant a lightning bolt fracturing the night sky.


Anyone who's been through a prolonged power outage knows that it's an extremely trying experience. Within an hour of losing electricity, you develop a healthy appreciation of all the electrical devices you rely on in life.

A couple hours later, you start pacing around your house. After a few days without lights, electric heat or TV, your stress level shoots through the roof. But in the grand scheme of things, that's nothing. If an outage hits an entire city, and there aren't adequate emergency resources, people may die from exposure, companies may suffer huge productivity losses and millions of dollars of food may spoil.

If a power outage hit on a much larger scale, it could shut down the electronic networks that keep governments and militaries running. We are utterly dependent on power, and when it's gone, things get very bad, very fast.


An electromagnetic bomb, or e-bomb, is a weapon designed to take advantage of this dependency. But instead of simply cutting off power in an area, an e-bomb would actually destroy most machines that use electricity.

High Power Electromagnetic Pulse generation techniques and High Power Microwave technology have matured to the point where practical E-bombs (Electromagnetic bombs) are becoming technically feasible, with new applications in both Strategic and Tactical Information Warfare. The development of conventional E-bomb devices allows their use in non-nuclear confrontations. This paper discusses aspects of the technology base, weapon delivery techniques and proposes a doctrinal foundation for the use of such devices in warhead and bomb applications.

An e-bomb (electromagnetic bomb) is a weapon that uses an intense electromagnetic field to create a brief pulse of energy that affects electronic circuitry without harming humans or buildings. At low levels, the pulse temporarily disables electronics systems; mid-range levels corrupt computer data. Very high levels completely destroy electronic circuitry, thus disabling any type of machine that uses electricity, including computers, radios, and ignition systems in vehicles. Although not directly lethal, an e-bomb would devastate any target that relies upon electricity: a category encompassing any potential military target and most civilian areas of the world as well.

Sixth Sense Technology May Change How We Look at the World Forever

I can't really describe Sixth Sense in a line. Sure, it is a system that projects information about what surrounds you over objects' surfaces, but it's also much more. You just have to watch it:

Basically, Sixth Sense is a mini-projector coupled with a camera and a cellphone—which acts as the computer and your connection to the Cloud, all the information stored on the web. Sixth Sense can also obey hand gestures, like in the infamous Minority Report.

However, instead of requiring you to be in front of a big screen like Tom Cruise, Sixth Sense can do its magic—and a lot more—everywhere, even while you are jumping hysteric over Oprah's sofa.

The camera recognizes objects around you instantly, with the micro-projector overlaying the information on any surface, including the object itself or your hand. Then, you can access or manipulate the information using your fingers. Need to make a call? Extend your hand on front of the projector and numbers will appear for you to click. Need to know the time? Draw a circle on your wrist and a watch will appear. Want to take a photo? Just make a square with your fingers, highlighting what you want to frame, and the system will make the photo—which you can later organize with the others using your own hands over the air.

But those are just novelty applications. The true power of Sixth Sense lies on its potential to connect the real world with the Internet, and overlaying the information on the world itself. Imagine you are at the supermarket, thinking about what brand of soap is better. Or maybe what wine you should get for tonight's dinner. Just look at objects, hold them on your hands, and Sixth Sense will show you if it's good or bad, or if it fits your preferences or not.

Now take this to every aspect of your everyday life. You can be in a taxi going to the airport, and just by taking out your boarding pass, Sixth Sense will grab real time information about your flight and display it over the ticket. You won't need to do any action. Just hold it in front of your and it will work.

The key here is that Sixth Sense recognizes the objects around you, displaying information automatically and letting you access it in any way you want, in the simplest way possible.

Clearly, this has the potential of becoming the ultimate "transparent" user interface for accessing information about everything around us. If they can get rid of the colored finger caps and it ever goes beyond the initial development phase, that is. But as it is now, it may change the way we interact with the real world and truly give everyone complete awareness of the environment around us.
