[40](arstechnica.com) Posted by EditorDavid on Sunday June 30, 2024 @12:34PM from the power-plays dept. [41]Bloomberg and [42]The Washington Post "claim AI power usage is dire," writes Slashdot reader [43]NoWayNoShapeNoForm. But Ars Technica "[44]begs to disagree with those speculations." From Ars Technica's article: The high-profile pieces lean heavily on recent projections [45]from Goldman Sachs and the [46]International Energy Agency (IEA) to cast AI's "insatiable" demand for energy as an almost apocalyptic threat to our power infrastructure. The Post piece even cites anonymous "some [people]" in reporting that "some worry whether there will be enough electricity to meet [the power demands] from any source." Digging into the best available numbers and projections available, though, it's hard to see AI's current and near-future environmental impact in such a dire light... While the headline focus of both Bloomberg and The Washington Post's recent pieces is on artificial intelligence, the actual numbers and projections cited in both pieces overwhelmingly focus on the energy used by Internet "data centers" as a whole... Bloomberg asks one source directly "why data centers were suddenly sucking up so much power" and gets back a blunt answer: "It's AI... It's 10 to 15 times the amount of electricity." Unfortunately for Bloomberg, that quote is followed almost immediately by a chart that heavily undercuts the AI alarmism. That chart shows worldwide data center energy usage growing at a remarkably steady pace from about 100 TWh in 2012 to around 350 TWh in 2024. The vast majority of that energy usage growth came before 2022, when the launch of tools like Dall-E and ChatGPT largely set off the industry's current mania for generative AI. If you squint at Bloomberg's graph, you can almost see the growth in energy usage slowing down a bit since that momentous year for generative AI. Ars Technica first cites Dutch researcher Alex de Vries's estimate that in a few years the AI sector could use [47]between 85 and 134 TWh of power. But another study estimated in 2018 that PC gaming already accounted for [48]75 TWh of electricity use per year, while "the IEA [49]estimates crypto mining ate up 110 TWh of electricity in 2022." More to the point, de Vries' AI energy estimates are only a small fraction of the 620 to 1,050 TWh that data centers as a whole are projected to use by 2026, according to the IEA's recent report. The vast majority of all that data center power will still be going to more mundane Internet infrastructure that we all take for granted (and which is not nearly as sexy of a headline bogeyman as "AI"). The future is also hard to predict, the article concludes. "If customers don't respond to the hype by actually spending significant money on generative AI at some point, the tech-marketing machine will largely move on, as it did very recently with the metaverse and [50]NFTs..." apply tags__________ 174345277 story [51]Linux [52]New Linux 'Screen of Death' Options: Black - or a Monochrome Tux Logo [53](phoronix.com) [54]9 Posted by EditorDavid on Sunday June 30, 2024 @11:34AM from the penguin-power dept. It was [55]analgous to the "Blue Screen of Death" that Windows gives for critical errors, Phoronix wrote. To enable error messages for things like a kernel panic, Linux 6.10 introduced a new panic handler infrastructure for "Direct Rendering Manager" (or DRM) drivers. Phoronix also published [56]a follow-up from Red Hat engineer Javier Martinez Canillas (who was involved in the new DRM Panic infrastructure). Given complaints about being too like Microsoft Windows following his recent Linux "Blue Screen of Death" showcase... Javier showed that a black screen of death is possible if so desired... After all, it's all open-source and thus can customize to your heart's content. And now the panic handler is getting even more new features, Phoronix reported Friday: With the code in Linux 6.10 when DRM Panic is triggered, an ASCII art version of Linux's mascot, Tux the penguin, is rendered as part of the display. With Linux 6.11 it will also be able to handle displaying a monochrome image as the logo. If ASCII art on error messages doesn't satisfy your tastes in 2024+, the DRM Panic code will be able to support a monochrome graphical logo that leverages the Linux kernel's boot-up logo support. The ASCII art penguin will still be used when no graphical logo is found or when the existing "LOGO" Kconfig option is disabled. (Those Tux logo assets being [57]here.) This monochrome logo support in the DRM Panic handler was sent out as part of this week's [58]drm-misc-next pull request ahead of the Linux 6.11 merge window in July. This week's drm-misc-next material also includes TTM memory management improvements, various fixes to the smaller Direct Rendering Manager drivers, and also the previously talked about [59]monochrome TV support for the Raspberry Pi. Long-time Slashdot reader [60]unixbhaskar thinks the new option "will certainly satisfy the modern people... But it is not as eye candy as people think... Moreover, it is monochrome, so certainly not resource-hungry. Plus, if all else fails, the ASCII art logo is still there to show!" apply tags__________ 174347377 story [61]Power [62]New Undersea Power Cables Could Carry Green Energy From Country to Country [63](cnn.com) [64]21 Posted by EditorDavid on Sunday June 30, 2024 @10:34AM from the international-energy dept. What if across the bottom of the Atlantic Ocean, six high-voltage power cables stretched -- each over 2,000 miles long. CNN reports that a group of entrepreneurs "wants to build what would be [65]the worldâ(TM)s largest subsea energy interconnector between continents, linking Europe and North America...to connect places like the United Kingdomâ(TM)s west with eastern Canada, and potentially New York with western France... "The Europe-US cables could send 6 gigawatts of energy in both directions at the speed of light, said Laurent Segalen, founder of the London-based Megawatt-X renewable energy firm, who is also part of the trio proposing the transatlantic interconnector. Thatâ(TM)s equivalent to what six large-scale nuclear power plants can generate, transmitted in near-real time." The interconnector would send renewable energy both east and west, taking advantage of the sunâ(TM)s diurnal journey across the sky. âoeWhen the sun is at its zenith, we probably have more power in Europe than we can really use,â said Simon Ludlam, founder and CEO of Etchea Energy, and one of the trio of Europeans leading the project. âoeWeâ(TM)ve got wind and weâ(TM)ve also got too much solar. Thatâ(TM)s a good time to send it to a demand center, like the East Coast of the United States. Five, six hours later, itâ(TM)s the zenith in the East Coast, and obviously, we in Europe have come back for dinner, and we get the reverse flow,â he added. The transatlantic interconnector is still a proposal, but networks of green energy cables are starting to sprawl across the worldâ(TM)s sea beds. They are fast becoming part of a global climate solution, transmitting large amounts of renewable energy to countries struggling to make the green transition alone. But they are also forging new relations that are reshaping the geopolitical map and shifting some of the worldâ(TM)s energy wars down to the depths of the ocean... Already, energy cables run between several countries in Europe, most of them allied neighbors. Not all of them carry renewable power exclusively â" thatâ(TM)s sometimes determined by what makes up each countryâ(TM)s energy grid â"âbut new ones are typically being built for a green energy future. The UK, where land space for power plants is limited, is already connected with Belgium, Norway, the Netherlands and Denmark under the sea. It has signed up to a solar and wind link [66]with Morocco to take advantage of the North African countryâ(TM)s many hours of sunlight and strong trade winds that run across the equator. Similar proposals are popping up around the globe. A project called [67]Sun Cable seeks to send solar power from sunny Australia, where land is abundant, to the Southeast Asian nation of Singapore, which also has plenty of sun but very little room for solar farms. India and Saudi Arabia plan to link their respective power grids via the Arabian Sea, part of a broader economic corridor plan to connect Asia, the Middle East and Europe. apply tags__________ 174345647 story [68]Power [69]Fuel From Water? Visiting a Texas 'Green Hydrogen' Plant [70](msn.com) [71]58 Posted by EditorDavid on Sunday June 30, 2024 @07:34AM from the H-to-O dept. It transforms water into the fuel — one of the first fuel plants in the world to do so. The Washington Post visits a facility in Corpus Christi, Texas [72]using renewable energy to produce "green" hydrogen. The plant feeds water through machines that pull out its hydrogen atoms... [T]he hydrogen is chemically transformed into diesel for delivery trucks. This process could represent the biggest change in how fuel for planes, ships, trains and trucks is made since the first internal combustion engine fired up in the 19th century... Turning hydrogen into liquid fuel could help slash planet-warming pollution from heavy vehicles, cutting a key source of emissions that contribute to climate change. But to fulfill that promise, companies will have to build massive numbers of wind turbines and solar panels to power the energy-hungry process. Regulators will have to make sure hydrogen production doesn't siphon green energy that could go towards cleaning up other sources of global warming gases, such as homes or factories. Although cars and light trucks are shifting to electric motors, other forms of transport will likely rely on some kind of liquid fuel for the foreseeable future. Batteries are too heavy for planes and too bulky for ships. Extended charging times could be an obstacle for long-haul trucks, and some rail lines may be too expensive to electrify. Together, these vehicles represent [73]roughly half of emissions from transportation, the [74]fourth-biggest source of greenhouse gases. To wean machines off oil, companies like Infinium, the owner of this plant, are starting to churn out hydrogen-based fuels that — [75]in the best case — produce close to net zero emissions. They could also pave the way for a new technology, hydrogen fuel cells, to power planes, ships and trucks in the second half of this century. For now, these fuels are expensive and almost no one makes them, so the U.S. government, businesses and philanthropists including Bill Gates are investing [76]billions of dollars to build up a hydrogen industry that could cut eventually some of the most stubborn, hard-to-remove carbon pollution. Most [77]scenarios for how the world could avoid the worst effects of climate change [78]envision hydrogen cleaning up emissions in transportation, as well as in fertilizer production and steel and chemical refining. But if they're not made with dedicated renewable energy, hydrogen-based fuels could generate [79]even more pollution than regular diesel, creating a wasteful boondoggle that sets the world back in the fight against climate change. Their potential comes down to the way plants like this produce them... Only about 40 percent of the power on the [Texas] electric grid is from renewables, with the rest coming from natural gas and coal, according to [80]state data. That grid energy is what flows through the power line into the Infinium plant. "One day, heavy transportation may shift to fuel cells that run on pure hydrogen and emit only water vapor from their tailpipes," the article points out. But to accommodate today's carbon-burning vehicles, Infinium produces "chemical copies of existing fuels made with crude oil" by combining captured carbon with green hydrogen. "A truck running on diesel made from hydrogen using only renewable electricity would [81]create 89 percent fewer greenhouse gas emissions over the course of its lifetime than a truck burning diesel made from petroleum, according to a 2022 analysis from the European nonprofit Transport & Environment." apply tags__________ 174346967 story [82]NASA [83]NASA's Commercial Spacesuit Program Just Hit a Major Snag [84](arstechnica.com) [85]46 Posted by EditorDavid on Sunday June 30, 2024 @03:34AM from the what-not-to-wear dept. Slashdot reader [86]Required Snark shared [87]this article from Ars Technica: Almost exactly [88]two years ago, as it prepared for the next generation of human spaceflight, NASA chose a pair of private companies to design and develop new spacesuits. These were to be new spacesuits that would allow astronauts to both perform spacewalks outside the International Space Station as well as walk on the Moon as part of the Artemis program. Now, that plan appears to be in trouble, with one of the spacesuit providers — Collins Aerospace — expected to back out, Ars has learned. It's a blow for NASA, because the space agency really needs modern spacesuits. NASA's Apollo-era suits have long been retired. The current suits used for spacewalks in low-Earth orbit are four decades old. "These new capabilities will allow us to continue on the International Space Station and allows us to do the Artemis program and continue on to Mars," said the director of Johnson Space Center, Vanessa Wyche, during a celebratory news conference in Houston two years ago. The two winning teams were led by Collins Aerospace and Axiom Space, respectively. They were eligible for task orders worth up to $3.5 billion — in essence NASA would rent the use of these suits for a couple of decades. Since then, NASA has designated Axiom to work primarily on a suit for the Moon and the Artemis Program, and Collins with developing a suit for operations in-orbit, such as space station servicing... The agency has been experiencing periodic problems with the maintenance of the suits built decades ago, known as the Extravehicular Mobility Unit, which made its debut in the 1980s. NASA [89]has acknowledged the suit has exceeded its planned design lifetime. Just this Monday, the agency [90]had to halt a spacewalk after the airlock had been de-pressurized and the hatch opened due to a water leak in the service and cooling umbilical unit of Tracy Dyson's spacesuit. As a result of this problem, NASA will likely only be able to conduct a single spacewalk this summer, after [91]initially planning three, to complete work outside the International Space Station. Collins designed the original Apollo suits, according to the article. But a person familiar with the situation told Ars Technica that "Collins has admitted they have drastically underperformed and have overspent" on their work, "culminating in a request to be taken off the contract or renegotiate the scope and their budget." Ironically, the company's top's post on [92]their account on Twitter/X is still a repost of [93]NASA's February announcement that they're "getting a nextx-generation spacesuit" developed by Collins Aerospace, and saying that the company "recently completed a key NASA design milestone aboard a commercial microgravity aircraft." NASA's post said they needed the suit "In order to advance NASA's spacewalking capabilities in low Earth orbit and to support continued maintenance and operations at the [94]Space Station." apply tags__________ 174347179 story [95]United States [96]Will a US Supreme Court Ruling Put Net Neutrality at Risk? [97](msn.com) [98]126 Posted by EditorDavid on Saturday June 29, 2024 @11:34PM from the here-comes-the-judge dept. Today the Wall Street Journal reported that restoring net neutrality to America is "[99]on shakier legal footing after a Supreme Court decision on Friday shifted power away from federal agencies." "It's hard to overstate the impact that this ruling could have on the regulatory landscape in the United States going forward," said Leah Malone, a lawyer at Simpson Thacher & Bartlett. "This could really bind U.S. agencies in their efforts to write new rules." Now that [[100]the "Chevron deference"] is gone, the Federal Communications Commission is expected to have a harder time reviving net neutrality — a set of policies barring internet-service providers from assigning priority to certain web traffic... The Federal Communications Commission reclassified internet providers as public utilities under the Communications Act. There are pending court cases challenging the FCC's reinterpretation of that 1934 law, and the demise of Chevron deference heightens the odds of the agency losing in court, some legal experts said. "Chevron's thumb on the scale in favor of the agencies was crucial to their chances of success," said Geoffrey Manne, president of the International Center for Law and Economics. "Now that that's gone, their claims are significantly weaker." Other federal agencies could also be affected, according to the article. The ruling could also make it harder for America's Environmental Protection Agency to crack down on power-plant pollution. And the Federal Trade Commission face more trouble in court defending its recent ban on noncompete agreements. Lawyer Daniel Jarcho tells the Journal that the Court's decision "will unquestionably lead to more litigation challenging federal agency actions, and more losses for federal agencies." Friday a White House press secretary [101]issued a statement calling the court's decision "deeply troubling," and arguing that the court had "decided in the favor of special interests". apply tags__________ 174345941 story [102]Social Networks [103]Threads Expands Fediverse Beta, Letting Users See Replies (and Likes) on Other Fediverse Sites like Mastodon [104](theverge.com) [105]11 Posted by EditorDavid on Saturday June 29, 2024 @09:34PM from the pulling-on-loose-Threads dept. An anonymous Slashdot reader shared [106]this report from the Verge: Threads will now let people like and see replies to their Threads posts that appear on other federated social media platforms, the company [107]announced on Tuesday. Previously, if you made a post on Threads that was [108]syndicated to another platform like Mastodon, you wouldn't be able to see responses to that post while still inside Threads. That meant you'd have to bounce back and forth between the platforms to stay up-to-date on replies... [I]n a screenshot, Meta notes that you can't reply to replies "yet," so it sounds like that feature will arrive in the future. "Threads is Meta's first app built to be compatible with the fediverse..." according to a [109]Meta blog post. "Our vision is that people using other fediverse-compatible servers will be able to follow and interact with people on Threads without having a Threads profile, and vice versa, connecting communities..." [If you turn on "sharing"...] "Developers can build new types of features and user experiences that can easily plug into other open social networks, accelerating the pace of innovation and experimentation." And this week Instagram/Threads top executive Adam Mosseri [110]posted that Threads is "also expanding the availability of the fediverse beta experience to more than 100 countries, and hope to roll it out everywhere soon." apply tags__________ 174341237 story [111]Cloud [112]Could We Lower The Carbon Footprint of Data Centers By Launching Them Into Space? [113](cnbc.com) [114]92 Posted by EditorDavid on Saturday June 29, 2024 @06:34PM from the air-gapped dept. The Wall Street Journal reports that a European initiative studying the feasibility data centers in space "has [115]found that the project could be economically viable" — while reducing the data center's carbon footprint. And they add that according to coordinator Thales Alenia Space, the project "could also generate a return on investment of several billion euros between now and 2050." The study — dubbed Ascend, short for Advanced Space Cloud for European Net zero emission and Data sovereignty — was funded by the European Union and sought to compare the environmental impacts of space-based and Earth-based data centers, the company said. Moving forward, the company plans to consolidate and optimize its results. Space data centers would be powered by solar energy outside the Earth's atmosphere, aiming to contribute to the European Union's goal of achieving carbon neutrality by 2050, the project coordinator said... Space data centers wouldn't require water to cool them, the company said. The 16-month study [116]came to a "very encouraging" conclusion, project manager Damien Dumestier told CNBC. With some caveats... The facilities that the study explored launching into space would orbit at an altitude of around 1,400 kilometers (869.9 miles) — about three times the altitude of the International Space Station. Dumestier explained that ASCEND would aim to deploy 13 space data center building blocks with a total capacity of 10 megawatts in 2036, in order to achieve the starting point for cloud service commercialization... The study found that, in order to significantly reduce CO2 emissions, a new type of launcher that is 10 times less emissive would need to be developed. ArianeGroup, one of the 12 companies participating in the study, is working to speed up the development of such reusable and eco-friendly launchers. The target is to have the first eco-launcher ready by 2035 and then to allow for 15 years of deployment in order to have the huge capacity required to make the project feasible, said Dumestier... Michael Winterson, managing director of the European Data Centre Association, acknowledges that a space data center would benefit from increased efficiency from solar power without the interruption of weather patterns — but the center would require significant amounts of rocket fuel to keep it in orbit. Winterson estimates that even a small 1 megawatt center in low earth orbit would need around 280,000 kilograms of rocket fuel per year at a cost of around $140 million in 2030 — a calculation based on a significant decrease in launch costs, which has yet to take place. "There will be specialist services that will be suited to this idea, but it will in no way be a market replacement," said Winterson. "Applications that might be well served would be very specific, such as military/surveillance, broadcasting, telecommunications and financial trading services. All other services would not competitively run from space," he added in emailed comments. [Merima Dzanic, head of strategy and operations at the Danish Data Center Industry Association] also signaled some skepticism around security risks, noting, "Space is being increasingly politicised and weaponized amongst the different countries. So obviously, there is a security implications on what type of data you send out there." Its not the only study looking at the potential of orbital data centers, notes CNBC. "Microsoft, which has [117]previously trialed the use of a [118]subsea data center that was positioned 117 feet deep on the seafloor, is collaborating with companies such as Loft Orbital to explore the challenges in executing AI and computing in space." The article also points out that the total global electricity consumption from data centers could exceed 1,000 terawatt-hours in 2026. "That's roughly equivalent to the electricity consumption of Japan, according to the International Energy Agency." apply tags__________ 174344939 story [119]Science [120]Get Ready For Nuclear Clocks [121](arxiv.org) [122]42 Posted by EditorDavid on Saturday June 29, 2024 @05:34PM from the time-to-tell-time dept.

Founded in 1846, the not-for-profit Associated Press distributes its news stories to other news outlets. But are free online sites [131]putting those outlets at risk? This week the Associated Press wrote that a "crisis" in local and state news reporting "shows little signs of abating" — and that it's now [132]setting up "a sister organization that will seek to raise money" for those outlets. The organization, which will have a board of directors independent of the AP, will solicit philanthropic spending to boost this news coverage, both within the AP and through outside organizations, the news outlet said Tuesday. "We feel we have to lean in at this point, not pull back," said Daisy Veerasingham, the AP's president and CEO. "But the supporting mechanism — the local newspaper market that used to support this — can't afford to do that anymore." Veerasingham said she's been encouraged by preliminary talks with some funders who have expressed concern about the state of local journalism...

"The outdoor-apparel brand Patagonia has given 90 U.S. employees a choice," [138]reports Business Insider: "tell the company by Friday that you're willing to relocate or leave your job." [[139]Alternate URL here.] The employees all work in customer services, known at Patagonia as the customer-experience, or CX, team, and have been allowed to work remotely to field calls and inquiries. These workers received a text and email Tuesday morning about an "important" meeting... Two company executives, Amy Velligan and Bruce Old, told staff in a 15-minute video meeting that the team would be moving to a new "hub" model. CX employees are now expected to live within 60 miles of one of seven "hubs" — Atlanta; Salt Lake City; Reno, Nevada; Dallas; Austin; Chicago; or Pittsburgh. Workers were offered $4,000 toward relocation costs and extra paid time off. Those willing to relocate were told to do so by September 30. If CX staff are not willing to live near a hub city, they must leave the company. They were given 72 hours, until Friday, to confirm their decision... Access to company laptops and phones was shut off later that day until employees either agreed to relocate or said they wanted the severance, one affected CX worker said... Both employees who spoke to Business Insider believed this was because Patagonia didn't want to handle the increased demands of employees in states with higher costs of living. "We've been asking for raises for a long time, and they keep telling us that your wage is based on a Reno cost of living and where you choose to live is on you." According to the article, "The company hopes to bring staff together at the hubs at least once every six weeks for in-person training, company gatherings, or 'Activism Hours'." A company spokesperson described the changes as "crucial for us to build a vibrant team culture," and said there were workers who had been complaining about feeling disconnected. Though there may be another motive: "The reality is that our CX team has been running at 200% to 300% overstaffed for much of this year," she added. "While we hoped to reach the needed staffing levels through attrition, those numbers were very low, and retention remained high." One affected worker told Business Insider that the company's proposal "was very factual. If you don't live in these seven metro areas, you either need to move there or give us your stuff and hit the brick. If we don't respond by Friday, they will assume that we have chosen the severance package and we'll start that process." One worker added that the severance package they received was generous...

Lego teamed up with the European Space Agency [145]to make Lego pieces from actual meteorite dust, writes Engadget. "It's a proof of concept to show how astronauts could use moondust to build lunar structures." Consider the sheer amount of energy and money required to haul up building materials from Earth to the Moon. It would be a game changer to, instead, build everything from pre-existing lunar materials. There's a layer of rock and mineral deposits at the surface of the Moon, which is called [146]lunar regolith... However, there isn't too much lunar regolith here on Earth for folks to experiment with. ESA scientists made their own regolith by grinding up a really old meteorite. [4.5 billion years, [147]according to Lego's site, discovered in Africa in 2000.] The dust from this meteorite was turned into a mixture that was used to 3D print the Lego pieces. Voila. Moon bricks.

"The result is amazing," says ESA Science Officer Aidan Cowley [148]on the Lego site (though "the bricks may look a little rougher than usual. Importantly the clutch power still works, enabling us to play and test our designs.") "Nobody has built a structure on the Moon," Cowley said [149]in an ESA statement. "So it was great to have the flexibility to try out all kinds of designs and building techniques with our space bricks." And the bricks will also be "helping to inspire the next generation of space engineers," according to the ESA's announcement — since they'll be on display in select Lego stores in the U.S., Canada, the U.K., Spain, France, Germany, the Netherlands, and Australia through September 20th. apply tags__________ 174341529 story [150]Bitcoin [151]Linux Foundation Announces Intent to Form LF Decentralized Trust [152](linuxfoundation.org) [153]9 Posted by EditorDavid on Saturday June 29, 2024 @01:34PM from the chip-off-the-ol'-blockchain dept.

LF Decentralized Trust will serve as a neutral home for the open development of a broad range of ledger, identity, security, interoperability, scale, implementation, and related technologies... LF Decentralized Trust will also include new directed funding models that will drive strategic investments by members into individual projects and project resources. "With LF Decentralized Trust, we're expanding our commitment to open source innovation by embracing a wider array of decentralized technologies," said Jim Zemlin, Executive Director of the Linux Foundation. "This new, elevated foundation will enable the community to build a more robust ecosystem that drives forward transparency, security, and efficiency in global infrastructure." "After eight years of advancing the development of blockchain, decentralized identity and related technologies via the Hyperledger community, the time has come to broaden our effort and impact," said Daniela Barbosa, General Manager, Blockchain and Identity, the Linux Foundation. "Ledgers and ledger technologies are but one component of the decentralized systems that will underpin a digital-first global economy. LF Decentralized Trust is where we will gather and grow an expanded community and portfolio of technologies to deliver the transparency, reliability, security and efficiency needed to successfully upgrade critical systems around the world." The announcement includes quotes of support from numerous companies including Oracle, Siemens, Visa, Accenture, Citi, and Hitachi. Some highlights: * "The formation of the LF Decentralized Trust reflects the growing demand for open source resources that are critical to the management and functionality of decentralized systems." — CEO of Digital Asset * "The adoption of decentralized infrastructure is at an inflection point, reflecting the increasing demand from both enterprises and consumers for more secure and transparent digital transactions. As the industry leader for onchain data, blockchain abstraction, and interoperability, we're excited to see the formation of the LF Decentralized Trust and to expand our collaboration with leading financial institutions on advancing tokenized assets and the onchain economy at large." — CMO at Chainlink Labs. * "As a founding member of the Hyperledger Foundation, and given our unique position in the financial markets, we recognize the vast potential for open-source innovation and decentralized technologies when it comes to reducing risk, increasing resiliency and improving security. The expansion of Hyperledger Foundation into LF Decentralized Trust represents an exciting opportunity to continue expanding these groundbreaking technologies." — a managing director at DTCC apply tags__________ 174341629 story [157]The Almighty Buck [158]Colorado's Universal Basic Income Experiment Gets Surprising Results [159](coloradosun.com) [160]256 Posted by EditorDavid on Saturday June 29, 2024 @12:34PM from the Rocky-Mountain-hi dept. In November of 2022, "More than 800 people were selected to participate in the Denver Basic Income Project," [161]reports the Colorado Sun, "while they were living on the streets, in shelters, on friends' couches or in vehicles. One group received $1,000 a month, according to the article, while a second group received $6,500 in the first month, and then $500 for the next 11 months. (And a "control" group received $50 a month.) Amazingly, about 45% of participants in all three groups "were living in a house or apartment that they rented or owned by the study's 10-month check-in point, according to the research." The number of nights spent in shelters among participants in the first and second groups decreased by half. And participants in those two groups reported an increase in full-time work, while the control group reported decreased full-time employment. The project also saved tax dollars, according to the report. Researchers tallied an estimated $589,214 in savings on public services, including ambulance rides, visits to hospital emergency departments, jail stays and shelter nights... The study, which began in November 2022 with payments to the first group of participants, has been extended for an additional eight months, until September, and organizers are attempting to raise money to extend it further. apply tags__________ 174343843 story [162]The Internet [163]Japan Achieves 402 TB/s Data Rate - Using Current Fiber Technology [164](tomshardware.com) [165]20 Posted by EditorDavid on Saturday June 29, 2024 @11:34AM from the very-high-speed-int-ernet dept. Tom's Hardware reports that Japan's National Institute of Information and Communications Technology (working with the Aston Institute of Photonic Technologies and Nokia Bell) [166]set a 402 terabits per second data transfer record — over commercially available optical fiber cables. The NICT and its partners were able to transmit signals through 1,505 channels over 50 km (about 31 miles) of optic fiber cable for this experiment. It used six types of amplifiers and an optical gain equalizer that taps into the unused 37 THz bandwidth to enable the 402 Tb/s transfer speed. One of the amplifiers this was demonstrated with is a thulium-based doped fiber amplifier, which uses C-band or C+L band systems. Additionally, semiconductor optical amplifiers and Raman amplifiers were used, which achieved 256 Tb/s data rate through almost 20 THz. Other amplifiers were also used for this exercise which provided a cumulative bandwidth of 25 THz for up to 119 Tb/s data rate. As a result, its maximum achievable result surpassed the previous data rate capacity by over 25 percent and increased transmission bandwidth by 35 percent. "This is achievable with currently available technology used by internet service providers..." the article points out. "With 'beyond 5G' potential speeds achievable through commercially available cables, it will likely further a new generation of internet services." apply tags__________ [167]« Newer [168]Older » Slashdot Top Deals Slashdot Top Deals [169]Slashdot Deals Slashdot Poll Is NVIDIA: (*) Overvalued ( ) Undervalued ( ) Valued correctly ( ) Not sure / Show results (BUTTON) vote now [170]Read the 39 comments | 9270 votes Looks like someone has already voted from this IP.
