Satellite Internet Ilona Mask will transmit data at the speed of light

Elon Musk made a big statement on Twitter that will definitely add popularity to the Starlink satellite internet system, which is being deployed by his company SpaceX. It turns out that SpaceX will soon start launching new satellites – with lasers, and this is a fundamental moment.

The laser will ensure the transfer of information from satellite to satellite at a speed that will be 40% higher than the data transfer rate in modern optical fiber. It is generally accepted that data is transmitted in optical fiber at the speed of light, but in reality this conditional speed of light differs from the real one with which light travels in a vacuum. In the first case, a correction is made for the refractive index, which is approximately 1.44-1.46. Therefore, in an optical cable, the data transmission rate is approximately 208 189 206 m / s. If we are talking about the fact that the speed in inter-satellite connections Starlink will be 40% higher, then it will be approximately 291 464 888 m / s, and this is already approximately 97% of the speed of light in vacuum (299 792 458 m / s). Round up, and it turns out that the satellites of the Starlink system will exchange data with each other at the speed of light. What does it do? The use of such a fast laser data exchange channel will reduce the time spent by satellites to communicate with ground stations, as well as increase the coverage, since data will be transmitted across continents without returning to earth. In turn, SpaceX will be able, if not completely, then at least partially, to abandon ground stations.

Inter-satellite communication has already been mentioned by SpaceX in the second generation aircraft characterization along with other improvements. The company is expected to launch approximately 30,000 of these satellites, and those already in orbit will receive a number of upgrades.

For 25 years motherboards of well known brands like MSI Gigabyte

The data of the largest German retailer suggests that motherboards from well-known manufacturers have risen in price significantly in the past few years. This applies to both Intel CPU and AMD CPU models. But in fairness, it should be noted that motherboards based on AMD chipsets added a little less.

For 2.5 years, motherboards of well-known brands like MSI, Gigabyte and ASRock have risen in price in Europe by 35-40%

The average cost of a motherboard for Intel processors in November 2020 was 140.78 euros, the average price of such a motherboard now, as of March 2023, is already 197 euros. Growth – by 40%. In November 2020, the average cost of a motherboard for AMD processors was 120.5 euros, now it is 163 euros. Growth – by 35% with a little.

It is difficult to explain such an increase by inflation and the laws of the market alone. Most likely, the rise in price is due to the transition to DDR5 and the introduction of support for the PCIe 5 bus.

Crypto exchange Binance hid secret ties with China

Crypto exchange Binance has been hiding ties to China for several years, which contradicts management’s claims of leaving the country after the cryptocurrency crisis in 2017, according to the Financial Times.

Binance CEO Changpeng Zhao (CZ) and other top executives allegedly instructed employees on multiple occasions to hide the exchange’s presence in China. The latter included running an office until at least the end of 2019 and using a local bank to pay salaries.

“We no longer publish office addresses… people in China can directly say that we are not there,” the newspaper quoted Zhao as saying in a November 2017 work chat.

At the end of 2019, employees discussed a media report about Binance’s plans to establish a headquarters in Beijing.

“Reminder: We publicly have offices in Malta, Singapore and Uganda. Please do not confirm any other jurisdictions, including China,” said one of the posts.

From a work email, it appears that the company instructed newcomers on how to properly use a VPN to hide their location.

On Monday, Binance was sued by US regulators for allegedly serving US customers illegally. The U.S. Commodity Futures Commission also alleges that Binance “deliberately” did not disclose the location of its offices and that claims that the headquarters is located where Zhao is located reflect a “deliberate attempt to avoid regulation.”
