Scientists Develop Technology for Tracking Website Fraud

Researchers at the University of Arizona say they have developed a prototype system that can detect fake sites based on online fraud that already exists.

The system they developed is more accurate in tracking down fraudulent websites than similar systems that already exist.

Scientists also say that the detection of fake sites is very important, because the majority of users are still not able to detect internet security which ultimately results in great losses.

University of Arizona research team successfully classifies online fraud based on several characteristics such as length of URLs, number of links, literary type, and others. "The problems we face today is quite large.

Phony sites harm the industry billions of dollars. This is what we must prevent, "said Abbasi, a member of the research team.

Worlds Fastest Computer

On the dawn of 25 May 2008, IBM unveiled their gentle giant- the ‘roadrunner’. Do not mistake it with the cute little cartoon character that your children enjoy watching on TV, the roadrunner is actually the worlds fastest computer at present, and it is capable of processing 1.7 petaflops. On May 25th, the computer had achieved 1.06 petaflops, making it the worlds fastest computer. This lean and hungry machine is not a child’s toy and it is priced at an eye-popping amount of $133 million.

Built by IBM at the Los Alamos Laboratory in New Mexico, this is truly a one of its kind supercomputer, primarily because of the fact that this machine is built mostly on commodity parts, available off the shelf at any hardware store. The worlds fastest computer boasts of some great design techniques, which have made it one of the marvels of modern engineering and computer architecture.

Built for the National nuclear security administration department, this computer has 12,960 IBM powerXcell 8i CPUs in conglomeration with 6,480 AMD opteron microprocessor systems. These systems are connected via a new technique of CPU-Processor connection, known as the infiniband, using blade server architecture. Running on Fedora and Red hat enterprise editions, the worlds fastest computer is as easy to work with as any other computing device. Designed to predict the vulnerability and the safety of America’s ageing nuclear weapons, the worlds fastest computer computes the reaction of nuclear components and ingredients as time progresses. The roadrunner is a massive machine, and occupies almost 550 square meters of space.

The main area where the worlds fasts computer differs from a lot of other super computers is the fact that it uses a combination of two architectures wherein each AMD 64 opteron processor is combined in a hybrid architecture with a ‘cell’, manufactured by IBM using its patented ‘power architecture’ technology.

The building process of the roadrunner was divided into three broad phases. The first phase was concerned with the development of a cluster, on a smaller scale, of the AMD 64- Cell combination and to check its feasibility on a larger scale. The second phase was primarily concerned with building a prototype using the clusters developed in the first phase. The third phase was dedicated to reach a peak performance, which was aimed to be measured in petaflops. Additional clusters, architectural enhancements and some additional powerXcell systems were arranged in order to breach the petaflops limit. Thus the worlds fastest computer was born on May 25th, 2008.

Containing two different kinds of processors, one being for calculations and the other for performing normal computer functions (such as bootstrapping, process scheduling and memory management), the worlds fastest computer is an architectural marvel. The two cores of computations in the worlds fastest computer are the AMD opteron and the IBM powerXcell. While the Opteron runs at 1.8 GHz, the PowerXcell runs at 3.2 GHz. The roadrunner utilizes a total of 122,400 cores, with roughly 6,000 coming from the Opteron and the rest coming from the PowerXcell.The computational unit of the roadrunner is the ‘triblade’, which consists of two dual core opterons with 16 GB of RAM and four powerXcells, containing their own additional 16 GB of RAM. The complete CU or the computational unit is the main unit of computation in the roadrunner and consists of 180 such triblades, with each of these triblades connected to a 288 port Voltaire infiband switch. The Panasas file system is implemented through twelve system servers. Each triblade, therefore, has to pass though one of these servers to access the Panasas files system.

The overall structure which emerges out as the complete roadrunner model consists of eighteen CUs, or connected units, which are connected through a second infiniband switch. The whole architecture is a mammoth structure and is testimony to the huge computing potential of the worlds fastest computer, setting it far apart from the rest of the competition.

Google's Android Not Owned?

Android was originally or formerly owned by Google is not really.
Google's acquisition of Android.

The range of 2005, Google bought Android, Inc., a small company that just had to grow based in Palo Alto, California.
Some people go there once worked at Google, such as Rich Miner, co-founder Wilfire Communications, then there is Andy Rubin, founder of Danger [enterprise software services], Chris White, an engineer on the Web TV and Nick Sears, a former VP at T-Mobile.
Rubin and his colleagues began developing the Linux-based operating system for mobile phones and other mobile devices.

Their main target is to handset developers and operators.
According to Google the information, move the acquisition is a brilliant idea.
Throughout the history of Google, it is the right step and the most profitable companies.
Indirectly Android Andy Rubin as co-inventor and becoming part of the history of Google's products, as well as have responsibility for the continuity of the open source operating system.
Together with his team, Rubin was able to demonstrate that they can make Android be the center of attention at the time.

Andy Rubin

At first David Lawee who served as vice president of corporate development, was hesitant with his decision.
Because for two years after the acquisition, Rubin has not produced a commensurate payoff for Google.
Finally, Lawee have raised two thumbs up for Rubin with the advent of smart phones that rely on Android operating system as the basis in the not long after.
As we think they are also successful with the business.

Moreover, Android is a system that is easy to operate, is quite flexible and upgradeable.
Time passed, and the right moment for the world to witness the entry of Google's mobile phone to the market, as it will appear soon followed by rumors of new handsets branded Google.
Android handset that we encounter today.

Transfer 100 Terabytes Per Second, is It Possible?

Well, according to a group of scientists, yes. A new laser developed at the Karlsruhe Institute of Technology in Germany could transfer up to 100 terabits per second.

The first tests have confirmed a stable transfer of up to 26 terabits per second, or whatever it is, 26,000 or 26,000,000 Megabits Gigabits in a single second. To get an idea, an MP3 music track or a photograph of a conventional camera does not exceed 10 Megabytes (approximately 80 Mbits), so that could be transferred more than 300,000 photographs from one computer to another in one second.

The system is based on Fast Fourier Transform “, known by its acronym FFT and known in Castilian as the FFT. The new laser emits a signal of about 300 colors that contain different information packets. If this light information reaches recipients achieved adequate transfer a large amount of information in no time.

But not all compliments for this new technology under development, also has some problems that make it so far, commercially unviable. On the one hand, the price, because its cost is still high compared with other less unwieldy but effective technologies such as fiber optics. Moreover, the technology involves a disproportionate consumption of energy. As the BBC explained to Professor Wolfgang Freude, study co-author at the Institute of Technology Karlsruhe in Germany, “The problem was that we had only a laser, we had something like 370 lasers, tremendously expensive. These lasers, filled Information consume several kilowatts of energy. “

Researchers have come to get transfer speeds of 100 Tbits per second, but have told the BBC that have chosen not to focus their research in this area for their high technical and economic requirements.
