Sources confirm that some major US retail stores have installed Sony PlayStation 5 demo stands. Users have already tried the console in operation, and some even managed to capture the moment when the PlayStation 5 overheated and issued a corresponding message.

Your PlayStation 5 is too hot. Unplug your console and wait for the temperature to drop.

According to one of the versions, the problem was caused by the fact that the set-top box was placed in a tiny enclosed space behind the glass, where hot air is likely to accumulate.

To dissipate heat, the Sony PlayStation 5 is equipped with a 120mm fan, which is responsible for cooling both sides of the console. How effective such a system is, we will learn from the first customer reviews next week.

Previously, one of the insiders was able to measure the temperature of the PlayStation 5, Xbox Series S, and Xbox Series X. According to him, at peak load, the PlayStation 5 heats up to 65 C, this is the worst result among the three consoles.

The secret of flashes of light in the night sky revealed

Scientists at the University of North Carolina at Chapel Hill have uncovered the mystery of the origin of flares of light in the night sky, which is very similar to stars in astronomical images. It turned out that this phenomenon is associated with the growing mass of satellites and debris in near-earth orbit. This is reported in an article published in The Astrophysical Journal Letters.

According to new data, orbital flares occur about a thousand times per hour, with about a hundred visible to the naked eye away from city lighting. In astronomical research, reflected light from satellites can lead to false signals when looking for new phenomena in the sky. Studying outbreaks will help make observations more accurate.

For six months, scientists have recorded more than 100 thousand outbreaks. They were observed with the Evryscopes telescopes in California and Chile. The flares are generated by reflected light from non-operational spacecraft, as well as debris, including non-operational satellites, paint fragments, nuts, and bolts. To a ground observer, flares can be indistinguishable from “visual snow”, which looks like stationary eye noise.

In some cases, satellites can cause streaking in photographs, which is a separate class of events that needs to be studied.

Critical vulnerability found in Windows

A critical vulnerability has been discovered in Windows that is being used to compromise computers. This was reported on the Google Project Zero website.

Experts said that the bug refers to zero-day vulnerabilities, that is, to malicious systems against which protective mechanisms have not yet been developed. With the help of a bug, hackers can elevate the privileges of certain processes in the system to break it. The experts said that the cracking occurs through interaction with the Windows Kernel Cryptography Driver function, which causes a buffer overflow.

A study by Google Project Zero says that the new vulnerability is used together with the CVE-2020-15999 vulnerability in the Chrome browser, which experts discovered a few days ago. Using a system flaw, hackers are able to run malicious code inside the browser.

Google experts concluded that the zero-day vulnerability found is already being exploited by cybercriminals. Hacking with its help was organized on the latest version of Windows 10, but the exploit was also launched on older versions of the OS, in particular, Windows 7.

In July, cybersecurity experts talked about the oldest vulnerability that has allowed compromising Windows servers for 17 years. The problem affected Windows Server operating systems from 2003-2019. Experts rated it 10 out of 10 on the CVSS vulnerability scale.

U.S. Army testing smart glasses for service dogs

The U.S. military is testing augmented reality glasses for service dogs used in hostilities. It is reported that such a device will provide an opportunity to give commands from a distance. What new opportunities will open up for four-legged soldiers, as well as what other animals will be “called up” to serve in different countries around the world — in our material.

Especially for military dogs serving in the U.S. Army, were invented augmented reality glasses (AR), reports the BBC. This technology, which is called Command Sight, allows a person to give commands to a dog at a considerable distance from it. Service dogs working in a war environment can conduct reconnaissance or search for explosives on their own, but they need a movie therapist to guide them in the event of a dangerous situation.

Currently, human contact with a dog is made by hand signals or laser pointer, but both methods require an instructor to be in proximity to the animal. If AR glasses pass all the tests successfully and are widely used, the distance is no longer a problem.

With the glasses on his face, the dog sees a visual indicator that he will follow to get to the specified point. The filmmaker, in turn, will see the same thing as his ward sees.

“AR will be used to give commands and signals to dogs; a dog cannot interact with this technology the way a human does,” says Dr. Stephen Lee, a senior researcher at the Army Research Laboratory. He added that the entire military film community is “excited about the potential of this research.

Glasses worn on service dogs are not known to be new — they are used as protection or when visibility is poor, but the addition of augmented reality technology is the latest development.

Colleague Stephen Lee of the Royal Joint Institute for Defence Studies Justin Bronk agrees that the idea of AR glasses on dogs may seem like “crazy fun”, but in fact its usefulness is obvious.

“The ability to guide dogs with visual signals through augmented reality glasses without the need to maintain close physical proximity has obvious tactical advantages in various situations,” Bronck said.

Meanwhile, the armed forces and law enforcement agencies of different countries use not only dogs but also other animals as assistants to humans. For example, the Dutch police used specially trained eagles to throw themselves at “hostile” drones and grab the propeller with their claws, disabling them. At the same time, the trainers assured that the eagles perceived the drones as prey, and therefore do not attack other birds or people when it is necessary to release them.

In addition, the eagle does not need an operator who will control its work — the predator has enough of his hunting instinct to shoot down the drone.

At the end of 2017, it became known that the Netherlands decided to abandon the program because of the cost and complexity of training eagles. In the U.S., however, were interested in this experiment and began to study the behavior and hunting tactics of other winged predators — falcons. The U.S. Army believes that the data collected will help develop a protective system against drones, which will be as effective against flying targets as a live falcon.

In addition, the Israeli army for many years, along with people served llamas — they delivered weapons and ammunition right on the battlefield, being able to carry up to 60 kg of cargo. For several years, the authorities decided to replace most of the lamas with modern robots that have an increased carrying capacity.

Isn’t Paris pressure too high when developing a 5G network?

The tender for frequencies for 5G networks has been launched in France since Tuesday. In this regard, discussions about the opportunities and risks of this newest technology have once again heated up. Greens demanded to suspend 5G network expansion, and President Macron responded with a severe failure. Mass media believe that horses should not be driven away.

Legitimate questions require answers

The debate about 5G technology is being conducted using the wrong rhetoric, — says Le Monde:

“Those who are somehow against this innovation adjoin those who consider discussions about it a waste of time because the benefits of the technology are obvious to everyone. But in both cases, the finale is unproductive: ‘Pass by, there’s nothing to see!’ But it’s quite the opposite: it’s absolutely legitimate to question the impact of 5G on the economy, environment, and technical safety… Transport issues, development of the city of the future, production methods — all these areas can undergo major changes with the help of new technology. But what will it mean for the environment? What benefits will it bring to people who are analyzing their dependence on new technologies? By the way, what about personal data protection guarantees? All these questions need to be answered.

Everything is going too fast!

According to L’Obs, progress is alarming:

“It’s rare that any innovation has received such a strong response. Before, technical progress was synonymous with growth and growth was synonymous with well-being. Both in the camp of the Left and in the camp of the Right, this dogma was most widespread, but with the onset of global warming, such truths are scattered like a house of cards. The world has realized that our economic model leads us straight into a dead-end — replacing reflection with reflexes and putting us to sleep with a ‘technological bluff’, as philosopher Jacques Elleulptly put it. …. If 5G has caused this reaction, it is because it is the embodiment of evil that paralyzes us in the face of climate change. It is a new acceleration factor that encourages us to think carefully about every move.
