YOUNG HACKER IN THE WORLD - 2

Kevin Mitnick

Kevin Mitnick’s journey as a computer hacker has been so interesting and compelling that the U.S. Department of Justice called him the “most wanted computer criminal in U.S. history.” His story is so wild that it was the basis for two featured films.

What did he do? After serving a year in prison for hacking into the Digital Equipment Corporation’s network, he was let out for 3 years of supervised release. Near the end of that period, however, he fled and went on a 2.5-year hacking spree that involved breaching the national defense warning system and stealing corporate secrets.

Mitnick was eventually caught and convicted, ending with a 5-year prison sentence. After serving those years fully, he became a consultant and public speaker for computer security. he now runs Mitnick Security Consulting, LLC.

YOUNG HACKER IN THE WORLD - 1

Jonathan James

Jonathan James was known as “c0mrade” on the Internet. What is his ticket to fame? He was convicted and sent to prison for hacking in the United States–all while he was still a minor. At only fifteen years of age, he managed to hack into a number of networks, including those belonging to Bell South, Miami-Dade, the U.S. Department of Defense, and NASA.

Yes, James hacked into NASA’s network and downloaded enough source code to learn how the International Space Station worked. The total value of the downloaded assets equaled $1.7 million. To add insult to injury, NASA had to shut down their network for three whole weeks while they investigated the breach, which cost them $41,000.

The story of James has a tragic ending, however. In 2007, a number of high profile companies fell victim to a massive wave of malicious network attacks. Even though James denied any involvement, he was suspected and investigated. In 2008, James committed suicide, believing he would be convicted of crimes that he did not commit.

Artificial Intelligence (AI)

 Artificial Intelligence (AI)

Artificial Intelligence (AI) is a branch of Science which deals with helping machines finding solutions to complex problems in a more human-like fashion. This generally involves borrowing characteristics from human intelligence, and applying them as algorithms in a computer friendly way. A more or less flexible or efficient approach can be taken depending on the requirements established, which influences how artificial the intelligent behaviour appears. AI is generally associated with Computer Science, but it has many important links with other fields such as Maths, Psychology, Cognition, Biology and Philosophy, among many others. Our ability to combine knowledge from all these fields will ultimately benefit our progress in the quest of creating an intelligent artificial being. AI is one of the newest disciplines. It was formally initiated in 1956, when the name was coined, although at that point work had been under way for about five years. However, the study of intelligence is one of the oldest disciplines. For over 2000 years, philosophers have tried to understand how seeing, learning, remembering, and reasoning could, or should, be done. The advent of usable computers in the early 1950s turned the learned but armchair speculation concerning these mental faculties into a real experimental and theoretical discipline. Many felt that the new ``Electronic Super-Brains'' had unlimited potential for intelligence. ``Faster Than Einstein'' was a typical headline. But as well as providing a vehicle for creating artificially intelligent entities, the computer provides a tool for testing theories of intelligence, and many theories failed to withstand the test. AI has turned out to be more difficult than many at first imagined, and modern ideas are much richer, more subtle, and more interesting as a result. AI currently encompasses a huge variety of subfields, from general-purpose areas such as perception and logical reasoning, to specific tasks such as playing chess, proving mathematical theorems, writing poetry, and diagnosing diseases. Often, scientists in other fields move gradually into artificial intelligence, where they find the tools and vocabulary to systematize and automate the intellectual tasks on which they have been working all their lives. Similarly, workers in AI can choose to apply their methods to any area of human intellectual endeavour. In this sense, it is truly a universal field.

BOOSTING YOUR MIND BY PLAYING 3D VIDEO GAME

BOOST YOUR MING

Are you hooked to 3D video games? Well, if yes, that may not be too bad as new research reveals that playing 3D video games, besides being lots of fun, can also boost the formation of memories.

Along with adding to the trove of research that shows these games can improve eye-hand coordination and reaction time, this finding shows the potential for novel virtual approaches to helping people who lose memory as they age or suffer from dementia.

For their research, University of California-Irvine neurobiologists Craig Stark and Dane Clemenson recruited non-gamer college students to play either a video game with a passive, two-dimensional environment or one with an intricate, 3D setting for 30 minutes per day over two weeks.

Before and after the two-week period, the students took memory tests that engaged the brain's hippocampus, the region associated with complex learning and memory.

They were given a series of pictures of everyday objects to study. Then they were shown images of the same objects, new ones and others that differed slightly from the original items and asked to categorize them.

Recognition of the slightly altered images requires the hippocampus, Stark said.Students playing the video game improved their scores on the memory test, while the 2D gamers did not. Memory performance increased by 12 percent, the same amount it normally decreases between the ages of 45 and 70.

"First, the 3D games have a few things the 2D ones do not. They've got a lot more spatial information in there to explore. Second, they're much more complex, with a lot more information to learn Either way, we know this kind of learning and memory not only stimulates but requires the hippocampus," he added.

The study appeared in The Journal of Neuroscience.

li-fi TECHNOLOGY

li-fi    TECHNOLOGY

A new method of delivering data, which uses the visible spectrum rather than radio waves, has been tested in a working office.

Li-fi can deliver internet access 100 times faster than traditional wi-fi, offering speeds of up to 1Gbps (gigabit per second).
It requires a light source, such as a standard LED bulb, an internet connection and a photo detector.
It was tested this week by Estonian start-up Velmenni, in Tallinn.
Velmenni used a li-fi-enabled light bulb to transmit data at speeds of 10Gbps. Laboratory tests have shown theoretical speeds of up to 224Gbps.
It was tested in an office, to allow workers to access the internet and in an industrial space, where it provided a smart lighting solution.
Light might be the preferred option for transmitting data over long distances via cables, but when it comes to short range wireless, radio waves rule in the form of Wi-Fi and Bluetooth. Now Mexican company Sisoft, working with researchers from the Autonomous Technological Institute of Mexico (ITAM), has developed a wireless technology that transmits data in visible light emitted from LED lamps, while lighting the room at the same time. Called Li-Fi, which is short for light fidelity, the technology is what is known as Visible Light Communication (VLC). Unlike infrared based system. VLC involves transmitting data using light visible to the human eye. In this case it is transmitted as intermittent, imperceptible flickers of light emitted by LEDs. The team started out with audio, cabling up a protoboard table to a smartphone via its 3.5 mm audio jack. The protoboard table converted the audio signal into an optical signal that is transmitted by a special emitter across the spectrum of light generated by an LED lamp. At the receiving end, a receptor located in a speaker captured the signal and converted it back into an audio signal that was played by the speaker.

For wireless internet transmission, the principle is the same but makes use of a receptor device designed to be placed above a router. The router incorporates an LED lamp to transmit data so anyone falling within the halo of light emitted by the LED will be in range. However, only those with a receptor/transmitter device will be able to send and receive the signal.

The Sisoft team says it has used the technology to transmit audio, video and internet at rates of up to 10 gigabits per second. This is an improvement over similar Li-Fi systems developed at  siemens and pennsylvania state university that achieved transfer rates of 500 Mbps and 1.6 Gbps, respectively.

In addition to its impressive transfer rate, Sisoft also highlights other benefits of the technology. Since the data is transferred via light, there is no way to hack it, making it safer, (although no mention is made of how easy it would be to take a peek at the data someone else is receiving). Additionally, it could be used in areas such as hospitals where radiation equipment can block or disrupt wireless signals. And of course, it provides illumination at the same time.
