Synthetic Sensors Is a Sensor That Could Soon Make Homes Scary-Smart | WIRED

Posted by Venkatt Guhesan on May 11, 2017

Synthetic Sensors : a simple device that plugs into an electrical outlet and connects everything in the room. It can capture all of the the environmental data needed to transform a wide variety of ordinary household objects into smart devices.

Plug the module into an electrical outlet and it becomes the eyes and ears of the room, its 10 embedded sensors logging information like sound, humidity, electromagnetic noise, motion, and light (the researchers excluded a camera for privacy reasons). Machine learning algorithms translate that data into context-specific information about what’s happening in the room.

More importantly, I like this project because I’ve spotted a Particle Photon embedded at the core of the Synthetic Sensor.

Ancient, giant viruses are being unearthed in Arctic ice that’s at risk of melting

Posted by Venkatt Guhesan on May 10, 2017

Scientists working in the Arctic circle over the past few decades have unearthed several massive viruses that some say could be re-awakened if the permafrost that imprisons them dissolves.

Recently, some researchers have suggested that these enormous viruses could thaw out, escape, and make lots of people sick. It sounds like something out of a 1990s horror film. But you shouldn’t get too concerned — at least not yet.

The likelihood that these viruses will break free and sicken humans is slim.

Quantum Computing Demands a Whole New Kind of Programmer

Posted by Venkatt Guhesan on May 10, 2017

Quantum computers finally seem to be coming of age with promises of “quantum supremacy” by the end of the year. But there’s a problem—very few people know how to work them. The bold claim of achieving “quantum supremacy” came on the back of Google unveiling a new quantum chip design. The hyperbolic phrase essentially means building a quantum device that can perform a calculation impossible for any conventional computer.

The technology has a major challenge to overcome. Programming these devices is much harder than programming conventional computers.

For a start, building algorithms for these machines requires a certain level of understanding about the quantum physics that gives qubits their special properties. While you don’t need an advanced physics degree to get your head around it, it is a big departure from traditional computer programming.

Nanofridge could keep quantum computers cool enough to calculate

Posted by Venkatt Guhesan on May 10, 2017

Quantum computers need to be kept cool, just like regular computers, but an ordinary fan won’t cut it. A nanofridge that sorts electrons by temperature just might keep it cool enough to allow quantum compute.

Classical computers require built-in fans and other ways to dissipate heat, and quantum computers are no different. Instead of working with bits of information that can be either 0 or 1, as in a classical machine, a quantum computer relies on “qubits”, which can be in both states simultaneously – called a superposition – thanks to the quirks of quantum mechanics. Those qubits must be shielded from all external noise, since the slightest interference will destroy the superposition, resulting in calculation errors. Well-isolated qubits heat up easily, so keeping them cool is a challenge.

Over time the process has a selective chilling effect on the electrons as well: the hotter electrons jump the gap, while the cooler ones are left behind. The process removes heat from the system, much like how a refrigerator functions.

MIT physicists have found a brand new way to unleash graphene’s superconductive power

Posted by Venkatt Guhesan on May 10, 2017

 Physicists have found a new way to turn ‘wonder material’ graphene into a ridiculously powerful superconductor, capable of shuttling electricity with zero resistance.

That’s important, because if we could find a way to achieve superconductivity at room temperature, it would lead to vastly more efficient electronic devices, not to mention power lines. Right now, energy companies are losing about 7 percent of their energy as heat as a result of resistance in the grid.

In the latest study, physicists from MIT took a flake of graphene and sandwiched it between aluminium, which behaves like a superconductor at low temperatures.

Javascript: Embrace Arrow Functions

Posted by Venkatt Guhesan on May 3, 2017

Great article on JavaScript currying and arrow functions.

Here is an example of a function in Javascript:

const secret = function (msg) {
    return function () {
        return msg;
    };
};

The same function as currying or arrow function:

const secret = msg => () => msg;
