Utkarsh - The Contragravity

Imagine a future where every one of the billions of light bulbs in use today is a wireless hotspot delivering connectivity at speeds that can only be dreamed of with Wi-Fi. That's the goal of the man who invented such a technology, and this week Li-Fi took a step out of the domain of science fiction and into the realm of the real when it was shown to deliver speeds 100 times faster than current Wi-Fi technology in actual tests. Lifi internet is similar to Wi-fi. It is a wireless, bidirectional technology founded by Professor Harald Haas of  University of Edinburgh. Li-fi stands for Light fidelity which takes light from light-emitting diodes (LEDs) as a path to deliver networked, mobile, high-speed communication. Lifi is a wireless technology using LED lights to transmit data through network. Scientists have receive a speed of 224 gigabits per second in laboratories by using this technology and the expected speed in the in the outside world could be 1giga-byte (1GB) per seco...

MongoDB is changing the Business of Big Data Modern data is vast, unstructured, and at times unwieldy. It’s big and complicated, and we have big expectations for what it can do—and trying to store, process, and analyze all of it has led to the development of NoSQL databases. These document-based databases eschew the table-based structure of relational databases and let us group data more logically.                                         The leading NoSQL database, MongoDB, has come out ahead in the field for a few reasons. It is an open-source and cross-platform compatible data model. It also has some impressive built-in features that make it an excellent choice for businesses that need fast, flexible access to their data, whether it’s to make real-time, on-the-fly decisions, or to create tailored, data-driven experiences for users. It is also compatible with .NET, Java ...

In computing, multi-touch is technology that enables a surface (a trackpad or touchscreen) to recognize the presence of more than one or more than two points of contact with the surface. But it is a (miserably) failed product due to the fact that hands could get very tired with prolonged use, but Leap Motion wants to challenge this dark area again with a more advanced idea. It lets you control the desktop with fingers, but without touching the screen. It’s not your typical motion sensor, as Leap Motion allows you to scroll the web page, zoom in the map and photos, sign documentss and even play a first person shooter game with only hand and finger movements. The smooth reaction is the most crucial key point here. More importantly, you can own this future with just $70, a price of a premium PS3 game title! If this device could completely work with Oculus Rift to simulate a real-time gaming experience, gaming is going to get a major make-over.         ...

Controlling your device just with your eyes !! Sounds pretty cool isn't it? “In the past year eye tracking technology moved from being a promising technology to being adopted in commercial products in a wide array of consumer segments simultaneously,” says Oscar Werner, vice president of the eye tracking company Tobii Tech. Although the concept of eye tracking isn't new but the past year saw a rising interest in the technology with many startups and roll-out of devices and software that supports eye tracking. There’s a chance that soon eye tracking will be a standard feature of a new generation of smartphones, laptops and desktop monitors setting the stage for a huge re-evaluation of the way we communicate with devices—or how they communicate with us. Less expensive and more potent hardware, new open source software platforms and new easier and faster ways of obtaining data, used to train algorithm models, have driven the progress in eye tracking technology. ...

“ “ Go, go!” was the thought racing through Grégoire Courtine’s mind. The French neuroscientist was watching a macaque monkey as it hunched aggressively at one end of a treadmill. His team had used a blade to slice halfway through the animal’s spinal cord, paralyzing its right leg. Now Courtine wanted to prove he could get the monkey walking again. To do it, he and colleagues had installed a recording device beneath its skull, touching its motor cortex, and sutured a pad of flexible electrodes around the animal’s spinal cord, below the injury. A wireless connection joined the two electronic devices. The result: a system that read the monkey’s intention to move and then transmitted it immediately in the form of bursts of electrical stimulation to its spine. Soon enough, the monkey’s right leg began to move. Extend and flex. Extend and flex. It hobbled forward. “The monkey was thinking, and then boom, it was walking,” recalls an exultant Courtine, a professor with Switzerland’s Éco...

IBM has announced a milestone in its race against Google and other big tech firms to build a powerful quantum computer. Dario Gil, who leads IBM's quantum computing and artificial intelligence research division, said that the company's scientists have successfully built and measured a processor prototype with 50 quantum bits, known as qubits.  Quantum computing, a technology that is still in its early phases, uses the quirks of quantum physics to perform calculations at far higher speeds than current computers. IBM still has glitches to work out but the 50-qubit announcement is a sign of significant progress. While technologies like AI can find pattern buried in vast amounts of existing data, quantum computers will deliver solutions to important problems where patterns cannot be found and the number of possibilities that you need to explore to get to the answer are too enormous ever to be processed by classical computers.  A quantum computer is a comp...
