Nanotechnology will help build better screens for smartphones

The technological advances that have taken place in the past few years on the smartphone market have made these portable devices start to offer modern displays for ever-increasing picture quality. In a few years, however, it may be even better, thanks to the invention of Stephen Chou.

Chou is a Princeton University professor and scientist who has been specializing in nanotechnology for several years and is planning to use his expertise to build a completely new LED technology for smartphones. His research not only will greatly improve the efficiency of LEDs, but may also provide better image quality on smartphones.

Currently used LEDs are very inefficient, converting to light only 2-4 percent of the energy supplied, the rest is converted to heat. Although some researchers in the laboratory were 38 percent efficient, Chou went much further, and with his technology he managed to increase it to 60 percent.

Although the brightness of the LEDs can be a problem, as opposed to the opacity of the light, Chou managed to do it by using a special nanoparticle, which managed to increase the contrast by as much as 400 percent. The invention also has several other advantages, since improving the efficiency of the LEDs can simultaneously reduce the energy consumption, which translates into longer working hours of the entire device.…

Facebook is declaring war on medical marijuana

A few weeks ago, the American media reported that posting on medical marijuana portals could be considered a crime even though some states have legalized it. Facebook has therefore decided to protect its users, and by the way itself, and began the removal of sites devoted to this popular plant.

Some US states have legalized the sale of medical marijuana, but publishing online it can still be considered a crime. This is because, at federal level, it is still banned, so this action can be considered to promote intoxicants, and the author of the photo is likely to pay a fine or even hit the grids.

The case was widely echoed in the American media and triggered a Facebook response. The largest social networking site has begun to remove pages devoted to medical marijuana. The message sent to the owners of such sites indicates that the promotion of drug use has ceased to meet the terms and conditions of the portal, and therefore has been removed.…

Wikileaks publishes CIA spy tools

There was another large leak of information from the US intelligence agency. Vault7 is the code name for the latest Wikileaks publication, which reveals what spy tools are used by the CIA. IOS, Android or Windows? It does not matter what system you use, CIA knows all the gaps and knows how to use them.

The Vault7 is made up of 8761 documents, which, according to the site, make it unique, even on Wikileaks extensive. Analyzes are still ongoing, but now the scale and manner of CIA operation in the digital age is emerging.

The information includes detailed descriptions of exploits, ie vulnerabilities in software related to operating systems responsible for computers, mobile devices, and televisions.

Understanding vulnerabilities is just the way to get information, and Vault7 includes descriptions of malware (Wikileaks for obvious reasons has not provided the code itself) used by the Spyware Agency.

Interestingly, the CIA, when it comes to creating spyware, closely tracks and analyzes cybercrime attacks and the software it uses, and is eager to use ready-made solutions.

The Vault7 documents also confirm that the CIA shared some of the solutions with national agencies such as the NSA or the FBI, or the allied British intelligence service MI5.

Wikileaks publishes many interesting information about the technical aspects of the US intelligence agency’s activities. It is difficult to say, however, that this information should be “groundbreaking” – in the end it involves the work of spies to spy on.

Controversial is the leaked information tools themselves, because if they managed to reach them Wikileaks can not be excluded that they also hit the hands of cybercriminals. And they do not bother to collect information – data collected from the device can be used to break into bank accounts or to shop online on someone else’s credit cards.…

The world’s largest 3D screen

3D monitors are slowly becoming more and more present in store offers. It can not be ruled out that the target audience for this type of product is not small, but Sony’s latest work may raise some doubts.

At the IBEE (International Broadcast Equipment Exhibition) in Japan, 280-inch LED-backlit LEDs are shown. Dimensions of the device are 6.4 x 3.4 meters.

The whole consists of 70 smaller displays. The manufacturer claims that this product can be used in the advertising industry as it could be an electronic billboard.

However, it is puzzling that special glasses are needed to enjoy the three-dimensional image of the LCD display. Is Sony expected that soon everyone will be carrying them and will set up each time they go next to the three-dimensional ad displayed?…

Uber punished for misinformation

The Uber corporation was fined by the Federal Trade Commission. The company will pay a $ 20 million fine for misrepresenting earnings for its drivers.

Uber ads tempt potential drivers with high earnings and although they can earn, American officials have decided that in these promises the corporation UBER too far off the truth. The difference is so great that the Federal Trade Commission has imposed a $ 20 million fine on Uber as a misleading person willing to undertake work in this company. The FTC claims that in job offers Uber has deliberately suggested that for New York, the annual salary of Uber employees could be $ 90,000, while in San Francisco it would be $ 74,000.

After examining the amount of earnings, it turned out that less than 10 percent. Drivers are able to earn a declared amount, and the rest are far behind.

The FTC’s complaints also apply to the Vehicle Solutions program, which leverages a new car from the Uber. In job offers, the company said the weekly lease would cost the employee about $ 119, while the drivers themselves said they would never go below $ 200. This was the case from the end of 2013 to April 2015.

Uber also asserted that it offers the best financing terms for buying a vehicle. In fact, they were, however, one of the worst and many financial institutions offered much better conditions. To make matters worse, the company also misled employees, suggesting that there was no limit on the number of miles traveled while offering the lease.

This is not the first fine imposed on Uber for misleading. Last year the company had to pay 384 thousand. Penalties for misleading tip policy in the UberEats service. In addition, it has paid San Francisco and Los Angeles cities $ 10 million for a false statement about checking the drivers’ past.…
