SpaceX rocket wreckage puts on fantastic light show in the sky

Published

on

Yesterday evening, stargazers in Oregon and Washington witnessed an unusual phenomenon, similar to a “leisurely” meteor shower. Apparently, these were the remnants of a SpaceX Falcon 9 rocket, burning up during flight in the atmosphere.

SpaceX itself has not yet claimed responsibility for the spectacle, but numerous meteorologists and astronomers have already identified the lights in the sky as harmless rocket debris. IN this thread on the social network Twitter numerous examples of this spectacle can be enjoyed.

University of Washington astronomer James Davenport told NBC’s KING5:

“We had a really good show today thanks to SpaceX. This was the top, what we call the second stage, of the Falcon 9. It actually launched about three weeks ago and did exactly what it had to do: put the satellites into orbit. The only failure was that the stage did not complete its descent from orbit and subsequent combustion, so it did not fall when and where we expected it. It just delayed the fall for the last three weeks, and we were lucky and it flew overhead. “

Unlike the reusable first stage of the Falcon 9, which returns to Earth, the second stage usually remains in orbit, where it will gradually collapse, or is redirected into the atmosphere, where it burns up.

Scientists have learned to track gadgets using BLE signals

Published

Devices can be tracked by prints of their physical characteristics.

In the past few years, mobile devices have become more likely to use the Bluetooth Low Energy (BLE) protocol to transfer messages, which can pose a significant privacy risk, experts at UC San Diego warn.

Within the framework of research they examined the implementation of BLE in a number of popular models of smartphones, laptops and gadgets and found that devices can be traced back to their physical characteristics. The bottom line is that devices can have a unique fingerprint that can be used to determine where they were and when.

BLE messaging has become more common in phones, laptops, smartwatches and other gadgets due to the support of operating devices for functions such as Apple Continuity or Find My, which imply the use of the BLE standard.

Typically, applications using this protocol try to hide identifiable data by encrypting the device’s MAC address, but this does not help to hide the built-in hardware characteristics of the device, based on which it can be identified.

Experts have tested their theory on several devices, including the iPhone 10, Thinkpad X1 Carbon (Windows), MacBook Pro 2016 (macOS), Apple Watch 4 (watchOS), Google Pixel 5 (Android), and Bose QuietComfort 35. In most cases, they were able to get a fingerprint of the physical BLE chip and distinguish one device from another.

In the course of the study, the scientists faced some difficulties, for example, it turned out to be more difficult to distinguish devices operating on the same chipset model than to distinguish gadgets based on different chips. The device’s ability to identify was also influenced by its temperature and signal transmission power.

Using special equipment, the researchers intercepted BLE signals from 162 devices in public places and were able to identify 40% of them. In addition, the group recorded BLE signals from bystanders’ devices with COVID-19 tracking apps from Apple and Google for two days for 10 hours. Scientists managed to “uniquely identify” 47.1% of 647 MAC addresses.

In theory, the method can be used to track the Apple AirTag and Samsung SmartTag Plus Bluetooth trackers, the researchers noted.

The new Intel processors are likely to be more expensive than their predecessors. There are already prices for two new models in the US

Published

It looks like the new Intel processors will significantly raise the price bar. A large American network MicroCenter has already added a couple of new Alder Lake generation products to its range.

The Core i7-12700K is priced at $ 470, while the top-end Core i9-12900K will cost $ 670. For comparison, the Core i9-11900K has a MSRP of $ 550, and Intel’s flagship model has always cost about the same for many years.

Of course, there hasn’t been an official announcement yet, so we don’t know the recommended prices. But today we have already seen an example from Germany, where the price was also above $ 600.

At the same time, it is hardly worth blaming Intel for such a pricing policy. First, the new CPUs will be much more efficient than their predecessors. And secondly, the same Ryzen 5000 is also not cheap, and it is not yet clear if the Ryzen 9 5950X will be able to withstand in comparison with the new flagship of Intel.

Former US President Donald Trump has finally announced the launch of his own social network called Truth Social.

A limited beta launch is slated for November, with wider rollouts scheduled for the first quarter of next year.

I created Truth Social and TMGT (Trump Media and Technology Group) to counter the tyranny of big technology. We live in a world where the Taliban are on Twitter, but your beloved American president has been silenced

Recall that Trump’s Twitter and Facebook accounts are permanently blocked.

At the moment, a social networking site is already functioning, where those who wish can join the waiting list. There is also a link for pre-downloading the application on iOS.
