Quizzes on Facebook threat to privacy?

Many people love playing intellectual and sitting in front of the computer, often looking at Facebook to solve quizzes available there. Experts warn against this form of entertainment, because the applications available there may pose a threat to your privacy by collecting too much information about it.

Comparitech, which has reviewed several popular quiz apps available on a popular social networking site, found that they collect not only our personal information, but also their date and place of residence, education, information about their favorite sites or photos, browser information, language , An IP address, and even a list of friends tied to Facebook. It’s a lot of information for a simple game and so much data is gathering most applications.

Some applications give the user the ability to choose which information they want to share, but in many cases the program does not work properly if we try to restrict access to our data.

The biggest problem, however, is not that applications collect data, but for what they do. For example, the company, the creator of Most Used Words on Facebook, has a record in its rules that gives it the right to use the information even if the user deletes the account. They can also be stored on servers around the world, including in places where there is no legal protection of personal data. Although the company ensures that it will not share your data without informing you, but there is a record in the rules that can be considered as such notification. In other words, the company can freely sell the data to sell to whom it wants.…

Ryanair is testing streaming movies on airplanes

Irish airline Ryanair is testing a brand new service to improve flight comfort by providing entertainment on longer journeys. The new idea is to stream movies and TV programs directly to mobile devices belonging to passengers.

Most airlines have built-in screens built into the seats to keep passengers entertained and do not get bored during long hours. Low cost airlines can not afford such luxury, because for low ticket prices they have to save on everything. This does not mean, however, the need to give up small pleasures.

Most passengers have their own laptops, smartphones or tablets, so Ryanair came up with the idea to stream movies and series to such devices. This is a cheaper solution than screen installation and is equally functional. Moreover, the carrier does not intend to charge any extra fee, which is a very nice surprise. But there is nothing free, so the lines will want to compensate by displaying ads.…

Experimental unit, invisible to radars

Sea Shadow is one of the most exciting floating structures ever built. This experimental machine was supposed to check how much you can hide against the enemy radars. Its construction was commissioned to Lockheed Martin under the supervision of DARPA and US Navy.

The construction of the Sea Shadow unit in practice has tested the possibility of solving the problems of the American leadership at the turn of the 1970s and 1980s with the use of the stealth technology of the F-117 Nighthawk, or possibly the greatest automation of ship handling to reduce the crew needed to a minimum. It also tested how the new hull type will be tested in the ocean.

Completed in 1984, the ship, until 1993, remained a strictly secret project. He has never been officially accepted to service, despite the presence in the US Navy’s records. By the end of his days he remained an experimental unit that was not intended to carry out any mission.

Sea Shadow had nearly 600 tons of displacement, a length of 50 meters, and its engine was able to disperse the unit to 14 knots (26 km / h). The crew was only ten seamen. Its main problem was the very small space reserved for the crew. On board we could find 12 places on bunk beds, microwave, small fridge and a table.…

Microsoft server underwater servers

Large technology companies such as Google, Facebook and Microsoft have to constantly expand their server rooms not only to keep growing their customer data, but also to offer more and more cloud services. The problem, however, is the issue of cooling them, so Microsoft is working on a project called Project Natick, which aims to build server rooms under water.

Gigantic server rooms, consisting of thousands of computers, produce enormous amounts of heat. Delicate electronics does not like high temperatures, so it has to be cooled, and it generates enormous costs. So technology companies are looking for different solutions to provide cheap cooling, and that’s why Facebook built one of these under the Arctic Circle, so that ordinary air is used for cooling.

However, Microsoft has developed a slightly different cooling method. The company, which already owns more than a hundred server rooms scattered all over the world, is planning to go down with them now. Engineers have developed a concept for underwater servers located on the ocean floor and enclosed in sealed capsules, which are naturally cooled through water. Capsules with land would connect properly reinforced optical fibers for data transmission.

What’s more, such a solution would not only cool servers, but also power them, using marine-wave energy systems. And the added advantage of such an idea would be to reduce data delays because containers would be close to residential areas.…
