NASA “landed” the unique Boeing 747SP SOFIA. For 8 years he watched the universe from the stratosphere

Since first flying in 2007, a Boeing 747SP tail number N747NA, modified by NASA into a large flying telescope, has been circling the stratosphere observing the universe in infrared (just like James Webb). But the work of SOFIA (Stratospheric Observatory for Infrared Astronomy, Stratospheric Observatory for Infrared Astronomy) came to an end: on September 28, a unique aircraft completed its last flight.

The SOFIA project at one time proved to be an innovative way to look at the Universe in the infrared. Unlike ground-based telescopes, which find it difficult to “see” through the water vapor of the earth’s atmosphere, SOFIA observed space from a height of more than 12.5 km, which provided a better view compared to ground-based objects.

The SOFIA project started in 1996. The first flight with a 2.7 m telescope installed on board took place in 2010, but the device was fully operational only in 2014. From 2014 to 2019, the flying observatory completed its five-year mission, but the operation of the unique telescope was extended for another three years. All this time, SOFIA has been observing the Moon, planets, and stars. This telescope was able to detect water on the moon’s sunlit surface in 2020.

2022 has been a very productive year for SOFIA. According to FlightRadar24.com, the 44-year-old aircraft made 143 flights.

So, this year, the stratospheric observatory visited South America for the first time: within two weeks, the telescope was deployed in Chile to observe celestial objects that can only be seen in the latitudes of the Southern Hemisphere.

In July, during a storm in New Zealand, the aircraft received frontal damage due to the displacement of a ladder placed outside. After that, the aircraft returned to the base in Palmdale in California, but later performed several more flights. The project is closed due to the fact that its scientific productivity no longer justifies the operating costs.

Huobi and Tron Jointly Launch Dominica National Token – Dominica Coin

Huobi and Tron Jointly Launch Dominica National Token Dominica

Crypto exchange Huobi today announced a strategic agreement with the Tron network, DMC Labs, and the government of Dominica. As part of this deal, the parties will jointly issue the world’s first national token, Dominica Coin (DMC).

Moreover, at the same time, a virtual ID protocol called DID will also be launched on the Tron platform. DMC holders will automatically receive a “digital citizenship” of Dominica.

Dominica DIDs and DMCs will initially be released on the Tron network, which is Dominica’s national blockchain infrastructure. In the future, the developers plan to ensure the interaction of the DMC token with the Ethereum and BSC networks via the BitTorrent Chain protocol. Just like TRX and USDD tokens, DMC will have legal status in the Commonwealth of Dominica and can be used as a means of payment in this country.

DMC will be released on Huobi Prime. The exchange will conduct a distribution of DMC tokens and enable the Dominica DID application for each registered user, the announcement says.

DID holders can also use the ID to issue SBT tokens in the Tron ecosystem. This will open up the possibility for them to become Dominica citizens in a future blockchain-based metaverse.

After paying the fee, you can also receive a printed certificate of your status. However, it is not yet completely clear whether such a document will have legal force outside the country. DID can also be used to complete KYC verification, obtain a loan in Dominica, register a virtual company, and a number of other government services.

When the GeForce RTX 4090 is a wolf in sheep’s clothing. Card consumption can be reduced by 33% by sacrificing 8% performance

When the GeForce RTX 4090 is a wolf in sheeps

Contrary to early leaks and rumors, the GeForce RTX 4090 turned out to be very energy efficient and even more economical than the RTX 3090. But Nvidia’s new product can be made even less voracious.

When the GeForce RTX 4090 is a wolf in sheep's clothing.  Card consumption can be reduced by 33% by sacrificing 8% performance

The authors of the QuasarZone resource decided not only to achieve less power consumption from the RTX 4090, but also to achieve this in two different ways. The first is reducing the power limit, but the second is more complex – it is undervolting or reducing the voltage on the GPU.

As you can see from the diagrams, both methods are effective, and in both cases you can achieve an impressive reduction in power consumption with a slight drop in performance. In the case of power limit management, power consumption can be reduced to 268 W, with a loss of only about 6% of performance. Reducing the voltage allows you to achieve power consumption of only 232 watts, sacrificing less than 8% of performance.

Thus, the RTX 4090 can be turned into a mid-range card in terms of power consumption, while keeping its monstrous performance almost unchanged.

For some reason, new Intel processors do not support DLVR technology, designed to reduce power consumption

For some reason new Intel processors do not support DLVR

Intel was expected to endow Raptor Lake processors with DLVR (Digital Linear Voltage Regulator) technology. Information about it appeared last year. However, it has now become known that current Intel CPUs do not support it.

For some reason, new Intel processors do not support DLVR technology, designed to reduce power consumption

Information about DLVR was neither in Intel’s presentation, nor somewhere on the site describing Raptor Lake. However, the CPU DLVR Bypass Mode Enable item has appeared in the new BIOS of Asus motherboards. True, its activation does not lead to anything.

For some reason, new Intel processors do not support DLVR technology, designed to reduce power consumption

One of the overclockers from the Asus team said that the technology does not work because Intel eventually disabled it in the new generation of processors. For what reasons, it is not clear, but from the tests we know that, perhaps, in vain, since Raptor Lake turned out to be even more voracious than Alder Lake. However, next-generation CPUs may well support the new technology already fully, however, there is no clarity on this matter.

DLVR is a digital linear voltage regulator that complements the main one. This should allow a significant reduction in energy consumption.
