Slashdot: China Blocks Use of Intel and AMD Chips in Government Computers

China Blocks Use of Intel and AMD Chips in Government Computers Published on March 26, 2024 at 01:31AM China has introduced new guidelines that will mean US microprocessors from Intel and AMD are phased out of government PCs and servers [Editor's note: the link may be paywalled; non-paywalled source], as Beijing ramps up a campaign to replace foreign technology with homegrown solutions. From a report: The stricter government procurement guidance also seeks to sideline Microsoft's Windows operating system and foreign-made database software in favour of domestic options. It runs alongside a parallel localisation drive under way in state-owned enterprises. The latest purchasing rules represent China's most significant step yet to build up domestic substitutes for foreign technology and echo moves in the US as tensions increase between the two countries. Washington has imposed sanctions on a growing number of Chinese companies on national security grounds, legislated to encou...

Slashdot: Landlines Are Dying Out

Landlines Are Dying Out Published on March 26, 2024 at 12:51AM An anonymous reader shares a report: The number of landline users has plummeted with the rise of cellphones, and the 19th-century technology's days appear to be numbered. Providers like AT&T are looking to exit the business by transitioning customers to cellphones or home telephone service over broadband connections. But for many of the millions of people still clinging to their copper-based landline telephones, newer alternatives are either unavailable, too expensive, or are unreliable when it matters most: in an emergency. According to the National Center for Health Statistics, only a quarter of adults in the United States still have landlines and only around 5 percent say they mostly or only rely on them. The largest group of people holding onto their landlines are 65 and older. Meanwhile, more than 70 percent of adults are using wireless phones only. The copper lines used for traditional landlines carry electr...

Slashdot: Bitcoin 'Halving' Spurs Exodus of Old US Mining Computers Abroad

Bitcoin 'Halving' Spurs Exodus of Old US Mining Computers Abroad Published on March 26, 2024 at 12:11AM An anonymous reader shares a report: About 6,000 older Bitcoin mining machines in the US will soon be idled and sent to a warehouse in Colorado Springs where they'll be refreshed and resold to buyers overseas looking to profit from mining in lower-cost environs. Wholesaler SunnySide Digital operates the 35,000 square-foot facility taking in the equipment from a mining client. The outdated machines are among several hundred-thousand it expects to receive and refurbish around a major quadrennial update in the Bitcoin blockchain. Known as the halving, the late April event will slash the reward that's the main revenue stream for miners, who will try to lessen the impact by upgrading to the latest and most efficient technology. With electricity the biggest expense, mining companies including publicly traded giants Marathon Digital Holdings and Riot Platforms need to lowe...

Slashdot: Astronomers Demand Radio Silence at the Moon's Far Side, But Resistance May Be Futile

Astronomers Demand Radio Silence at the Moon's Far Side, But Resistance May Be Futile Published on March 25, 2024 at 12:04AM Gizmodo reports that increased activity on the Moon "may affect the unique radio silence on the lunar far side, an ideal location for radio telescopes to pick up faint signals from the cosmic past." This week, the International Academy of Astronautics (IAA) held the first Moon Farside Protection Symposium in Italy to advocate for preserving radio silence on the far side of the Moon. The symposium hopes to raise awareness about the threat facing the far side of the Moon and develop approaches to shielding it from artificial radio emissions.... NASA has shown interest in using the lunar radio silence, proposing an ultra-long-wavelength radio telescope inside a crater on the far side of the Moon. The Lunar Crater Radio Telescope is designed to observe the universe at frequencies below 30 megahertz, which are largely unexplored by humans since those s...

Slashdot: ''Tetris Reversed'? Alexey Pajitnov Shows Footage From Rediscovered Prototype for 'Tetris' Sequel

''Tetris Reversed'? Alexey Pajitnov Shows Footage From Rediscovered Prototype for 'Tetris' Sequel Published on March 24, 2024 at 03:04AM Tetris creator Alexey Pajitnov and others spoke at the Game Developers Conference about Tetris Reversed, reports VentureBeat — and told the story of "a lost prototype of a Tetris game that was never published." But little did Pajitnov know that an engineer in charge of the game, Vedran Klanac, had kept a copy of it. Through the help of intermediaries, he showed it to Pajitnov and the two shared their memories of what happened to the lost game... Pajitnov has lived in the U.S. since 1991, where he has been involved in the development of games such as Pandora's Box and worked with companies such as Microsoft and WildSnake Software... Klanac is the CEO of Ocean Media, and he is originally from Zagreb, Croatia. He was an aerospace engineer who started his career in the games industry with Croteam where he built the phys...

Slashdot: A Problem for Sun-Blocking Cloud Geoengineering? Clouds Dissipate

A Problem for Sun-Blocking Cloud Geoengineering? Clouds Dissipate Published on March 24, 2024 at 02:04AM Slashdot reader christoban writes: In what may be an issue for Sun-obscuring strategies to combat global warming, it turns out that during solar eclipses, low level cumulus clouds rapidly disappear, reducing by a factor of 4, researchers have found. The news comes from the science magazine Eos (published by the nonprofit organization of atmosphere/ocean/space scientists, the American Geophysical Union). Victor J. H. Trees, a geoscientist at Delft University of Technology in the Netherlands, and his colleagues recently analyzed cloud cover data obtained during an annular eclipse in 2005, visible in parts of Europe and Africa. They mined visible and infrared imagery collected by two geostationary satellites operated by the European Organisation for the Exploitation of Meteorological Satellites. Going to space was key, Trees said. "If you really want to quantify how clouds behav...

Slashdot: New 'Loop DoS' Attack May Impact Up to 300,000 Online Systems

New 'Loop DoS' Attack May Impact Up to 300,000 Online Systems Published on March 24, 2024 at 01:03AM BleepingComputer reports on "a new denial-of-service attack dubbed 'Loop DoS' targeting application layer protocols." According to their article, the attack "can pair network services into an indefinite communication loop that creates large volumes of traffic." Devised by researchers at the CISPA Helmholtz-Center for Information Security, the attack uses the User Datagram Protocol (UDP) and impacts an estimated 300,000 host and their networks. The attack is possible due to a vulnerability, currently tracked as CVE-2024-2169, in the implementation of the UDP protocol, which is susceptible to IP spoofing and does not provide sufficient packet verification. An attacker exploiting the vulnerability creates a self-perpetuating mechanism that generates excessive traffic without limits and without a way to stop it, leading to a denial-of-service (DoS) cond...
