TV Samsung UN105S9W for $120000

28.07.2014

Samsung Electronics, the world's largest TV manufacturer, has begun accepting bids for one of the world's most expensive TVs, the Samsung UN105S9W. Announced at CES 2014 in January, the model features a 105-inch curved display with a resolution of 5120 x 2160 pixels, 5,3 times more than Full HD and 1,3 times more than Ultra HD ( 4K).

Previously, Samsung has already explained why they produce TVs with concave screens. According to company representatives, such a screen allows you to get more vivid impressions due to the equal distance of all points of the image from the viewer's eyes.

The model has LED backlighting with local dimming technology, is equipped with four HDMI ports, Smart TV technology and a built-in 5.1W DTS Premium Sound 160 multi-channel speaker system. Also available: Wi-Fi support, four USB ports, 3D support. A 4-core processor is responsible for controlling the functions of the TV.

The cost of new items in the US is $120 thousand (about i 4,2 million). Western media note that with this money you can buy a house or a Porsche Carrera 4S Cabriolet 2014 sports car with a 400 hp engine, with a maximum speed of 293 km/h and acceleration time to 100 km/h - 4,5 s. The cost of such a car in the US market is $ 118 thousand.

It should be noted that the UN105S9W does not hold the title of the most expensive TV in the world. In March 2014, Samsung announced the price of a 110-inch TV at $150. This model has a flat screen with a resolution of 3820 x 2160 pixels. It was presented at CES in January 2013.

Those who are not ready to part with $120 can wait for the LG 105UC9 TV to start selling. It also has a 105-inch curved display. The resolution of its matrix is 3820 x 2160 pixels. The cost of this model is $70, which is $50 cheaper than Samsung's offer.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Vulnerability of USB devices 09.08.2014

German experts have discovered a fundamental vulnerability in all USB devices. When a device is infected, the user will simply have to throw it away, since the malicious code will be located directly in the chip responsible for its operation. No antivirus can reach this controller.

Any USB device can become a hacker's tool: a mouse, a flash drive, a keyboard, an external hard drive, or even a smartphone connected via a USB interface. This is warned by Jakob Lell and Karsten Nohl, experts at the German consulting firm Security Research Labs.

According to experts, every USB peripheral includes a chip - an interface controller - that can be easily reflashed. There is no protection that could prevent this action.

After flashing the USB controller, an attacker can, for example, emulate a USB keyboard, then enter commands on behalf of the user and install malicious software, penetrate the network card in order to change the DNS so that all Internet traffic flows through the hacker's node, or launch a virus into the operating system right during the PC boot (provided that the compromised device is connected to it at that moment).

"To date, we do not have information about effective methods of protection against such attacks," - say Lel and Nol. The antivirus installed on the PC will never know that the controller firmware has been changed, because it simply does not have access to this chip. Firewalls that could block USB devices of a certain class do not yet exist. And even behavioral analysis technologies are not suitable in such a case, since emulation of another device will be perceived only as a device change by the user himself.

Experts believe that if the system is infected in this way, the problem will be very difficult to fix. Even reinstalling the OS will not help get rid of viruses, since they will be inside the controllers, and not on the hard drive with system files. The virus can also infect other devices that are connected to the PC via USB, such as a webcam or speaker system.

"After a PC is infected, all peripheral devices that are connected to it via a USB interface can never be trusted," the experts conclude.

At the Black Hat conference, which will be held in Las Vegas (USA), the researchers plan to present a report on the discovered new type of vulnerability.
