Apple No Longer In Talks To Invest In OpenAI

Slashdot - Tue, 2024-10-01 00:00
Apple has withdrawn from discussions to invest in OpenAI's $6.5 billion funding round, though reasons for the decision remain unclear. The company still plans to proceed with integrating ChatGPT into Siri. MacRumors reports: The development comes just a month after WSJ reported that Apple was considering an investment in OpenAI as part of a fundraising effort that could value the AI company at over $100 billion. The high valuation reflects the intense competition in the artificial intelligence sector that OpenAI helped ignite with ChatGPT's launch in late 2022. While Apple has stepped away, other major tech companies remain involved. Microsoft, which has already invested $13 billion in OpenAI, is expected to contribute about $1 billion to this latest round. Nvidia is also reportedly in talks to participate. OpenAI's transition into a for-profit structure may have factored into Apple's decision. Last week, Reuters reported on OpenAI's plan to restructure its core business into a for-profit benefit corporation that will no longer be controlled by its non-profit board. "Chief executive Sam Altman will also receive equity for the first time in the for-profit company, which could be worth $150 billion after the restructuring as it also tries to remove the cap on returns for investors," reported Reuters.

California Bans Legacy Admissions At Private, Nonprofit Universities

Slashdot - Mon, 2024-09-30 23:20
An anonymous reader quotes a report from Politico: It will soon be illegal for public and private universities in California to consider an applicant's relationship to alumni or donors when deciding whether to admit them. Gov. Gavin Newsom on Monday signed a ban on the practice known as legacy admissions, a change that will affect prestigious institutions including Stanford University and the University of Southern California. California's law, which will take effect Sept. 1, 2025, is the nation's fifth legacy admissions ban, but only the second that will apply to private colleges. "In California, everyone should be able to get ahead through merit, skill, and hard work," Newsom said in a statement. "The California Dream shouldn't be accessible to just a lucky few, which is why we're opening the door to higher education wide enough for everyone, fairly." Like other states, California won't financially penalize violators, but it will post the names of violators on the state Department of Justice's website. California will also add to data reporting requirements that it implemented in 2022, when private colleges had to start sharing the percentage of admitted students who were related to donors and alumni. Schools that run afoul of the new law will also have to report more granular demographic information about their incoming classes to the state, including the race and income of enrolled students as well as their participation in athletics. [...] Public universities in California won't be affected by the change. California State University does not consider legacy or donor ties, and the University of California system stopped doing so in 1998, two years after California voters banned race-conscious admissions through a statewide ballot measure.

Mazda's $10 Subscription For Remote Start Sparks Backlash After Killing Open Source Option

Slashdot - Mon, 2024-09-30 22:42
An anonymous reader shares a report: Mazda recently surprised customers by requiring them to sign up for a subscription in order to keep certain services. Now, notable right-to-repair advocate Louis Rossmann is calling out the brand. He points to several moves by Mazda as reasons for his anger toward them. However, it turns out that customers might still have a workaround. Previously, the Japanese carmaker offered connected services, that included several features such as remote start, without the need for a subscription. At the time, the company informed customers that these services would eventually transition to a paid model. It's important to clarify that there are two very different types of remote start we're talking about here. The first type is the one many people are familiar with where you use the key fob to start the vehicle. The second method involves using another device like a smartphone to start the car. In the latter, connected services do the heavy lifting. What is wild is that Mazda used to offer the first option on the fob. Now, it only offers the second kind, where one starts the car via phone through its connected services for a $10 monthly subscription, which comes to $120 a year. Rossmann points out that one individual, Brandon Rorthweiler, developed a workaround in 2023 to enable remote start without Mazda's subscription fees.

Massive E-Learning Platform Udemy Gave Teachers a Gen AI 'Opt-Out Window'. It's Already Over.

Slashdot - Mon, 2024-09-30 21:20
An anonymous reader shares a report: Udemy, an e-learning platform with more than 250,000 online classes, recently announced that it would train generative AI on the classes that its users contribute to the site. Not only were class teachers automatically opted in to having their classes used as training, Udemy said teachers would have only a three-week "window" to opt-out of training. That window has now passed. "We want to officially announce that the opt-out period for our Generative AI Program (GenAI Program) begins today, August 21st, and goes through September 12th. The choice to participate in the GenAI program is yours. If you want to participate, no action is needed!," Udemy said in a post on its community forums August 21. In an "Instructor Generative AI Policy" document, it says it plans to offer "Annual Periods designated by us" during which instructors can opt-out of having their classes trained on, and said that when people opt-out of training, it will remove the instructors' classes from its dataset "by the end of the calendar year." It has also told instructors that "By opting out, you'll lose access to all AI features and benefits, which may affect your course visibility and potential earnings." With the first opt-out window having passed, instructors are now seeing a grayed-out option in their settings if they didn't know about the window or would like to opt-out now.

DirecTV To Buy Rival Dish Network

Slashdot - Mon, 2024-09-30 20:41
DirecTV has agreed to acquire struggling rival Dish Network, creating a satellite TV behemoth with nearly 20 million subscribers. The complex transaction, announced Monday, involves private equity firm TPG acquiring a majority stake in DirecTV from AT&T for $7.6 billion. DirecTV will then purchase Dish for $1 and assume its debt. The deal provides a lifeline for Dish, which faces $2 billion in debt due November with only $500 million in available cash. EchoStar, Dish's parent company, will retain its wireless spectrum investments and operate independently. Subject to regulatory approval and creditor agreement, the merger is expected to close in late 2025. DirecTV and TPG will provide $2.5 billion to cover Dish's immediate financial needs. The deal's fate remains uncertain, as a similar 2002 merger attempt was blocked on antitrust grounds.

Reddit has implemented new restrictions on moderators' ability to alter community visibility settings, the social media platform announced Monday. Moderators must now obtain admin approval before switching subreddits between public, private, or NSFW status. The move comes in response to last year's widespread protests against API pricing changes, during which thousands of subreddits went private, disrupting platform accessibility. Reddit VP Laura Nestler stated the policy aims to prevent actions that "deliberately cause harm" and protect the site's long-term health.

US Approves Billions in Aid To Restart Michigan Nuclear Plant

Slashdot - Mon, 2024-09-30 19:20
The Energy Department said on Monday that it had finalized a $1.52 billion loan guarantee to help a company restart a shuttered nuclear plant in Michigan -- the latest sign of rising government support for nuclear power. From a report: Two rural electricity providers that planned to buy power from the reactor would also receive $1.3 billion in federal grants [Editor's note: the link is likely paywalled; alternative source] under a program approved by Congress to help rural communities tackle climate change. The moves will help Holtec International reopen the Palisades nuclear plant in Covert Township, Mich., which ceased operating in 2022. The company plans to inspect and refurbish the plant's reactor and seek regulatory approval to restart the plant by October 2025. After years of stagnation, America's nuclear industry is seeing a resurgence of interest. Both Congress and the Biden administration have offered billions of dollars in subsidies to prevent older nuclear plants from closing and to build new reactors. Despite concerns about high costs and hazardous waste, nuclear plants can generate electricity at all hours without emitting the greenhouse gases that are heating the planet. David Turk, the deputy secretary of energy, said he expected U.S. electricity demand would grow by 15 percent over the next few years, driven by an increase in electric vehicles, a boom in battery and solar factories as well as a surge of new data centers for artificial intelligence. That meant the nation needs new low-carbon sources of power that could run 24/7 and complement wind and solar plants.

UK Ends 142-Year Coal Power Era in Industry's Birthplace

Slashdot - Mon, 2024-09-30 18:40
AmiMoJo writes: The UK is about to stop producing any electricity from burning coal -- ending its 142-year reliance on the fossil fuel. The country's last coal power station, at Ratcliffe-on-Soar, finishes operations on Monday after running since 1967. This marks a major milestone in the country's ambitions to reduce its contribution to climate change. Coal is the dirtiest fossil fuel producing the most greenhouse gases when burnt. The UK was the birthplace of coal power, and from tomorrow it becomes the first major economy to give it up. The first coal-fired power station in the world, the Holborn Viaduct power station, was built in 1882 in London by the inventor Thomas Edison -- bringing light to the streets of the capital. In the early 1990s, coal began to be forced out of the electricity mix by gas, but coal still remained a crucial component of the UK grid for the next two decades. In 2012, it still generated 39% of the UK's power. In 2010, renewables generated just 7% of the UK's power. By the first half of 2024, this had grown to more than 50% -- a new record. The rapid growth of green power meant that coal could even be switched off completely for short periods, with the first coal-free days in 2017.

Verizon Cellphone Users Report Outages Across the US

Slashdot - Mon, 2024-09-30 18:04
Thousands of Verizon users across the United States reported having little or no cellphone service on Monday morning in major cities, including in Atlanta, Chicago, Denver, New York and Phoenix. From a report: According to the website Downdetector, which tracks user reports of internet disruptions, more than 104,000 cases of Verizon outages were reported across the country as of 11:20 a.m. Eastern, more than an hour after the first issues were reported. A map posted on the site showed cities with the most reports. On the site, many users said their cellphones were intermittently displaying SOS mode and that they could not place calls or send or receive text messages. "We're aware of the issue affecting service for some customers," a spokesman for Verizon, Ilya Hemlin, said in a telephone interview at 11:30 a.m. "Our engineers are engaged and we are working quickly to solve the issue," he added.

Songs by Adele, Bob Dylan, Green Day, Many More Blocked by YouTube in Legal Dispute

Slashdot - Mon, 2024-09-30 17:20
An anonymous reader shares a report: Songs by Adele, Bob Dylan, Green Day, R.E.M., Burna Boy, Rush and many others are currently unplayable on YouTube in the U.S. due to a legal dispute between the platform and the performing rights organization SESAC. Attempts to play many, but not all, songs by those artists on Saturday met with the following message: "This video contains content from SESAC. It is not available in your country." A similar dispute between Universal Music Group and TikTok raged on for several months earlier this year before being resolved. In a statement to Variety, a YouTube rep said: "We have held good faith negotiations with SESAC to renew our existing deal. Unfortunately, despite our best efforts, we were unable to reach an equitable agreement before its expiration. We take copyright very seriously and as a result, content represented by SESAC is no longer available on YouTube in the US. We are in active conversations with SESAC and are hoping to reach a new deal as soon as possible." A source close to the situation tells Variety that the previous deal actually does not expire until next week, and suggests that YouTube's move is a negotiating tactic. SESAC is far smaller than ASCAP and BMI -- with approximately 30,000 members and 1.5 million compositions while ASCAP has nearly 800,000 members -- but as the caliber of artists affected by the block shows, it represents a comparatively large percentage of the marketplace.

Epic Games Sues Google and Samsung Over App Store Restrictions

Slashdot - Mon, 2024-09-30 16:00
Epic Games filed a new antitrust lawsuit against Google and Samsung, alleging they conspired to undermine third-party app stores. The suit focuses on Samsung's "Auto Blocker" feature, now enabled by default on new phones, which restricts app installations to "authorized sources" - primarily Google and Samsung's stores. Epic claims Auto Blocker creates significant barriers for rival stores, requiring users to navigate a complex process to install third-party apps. The company argues this feature does not actually assess app safety, but is designed to stifle competition. Epic CEO Tim Sweeney stated the lawsuit aims to benefit all developers, not secure special privileges for Epic. The company seeks either default deactivation of Auto Blocker or creation of a fair whitelisting process for legitimate apps. This legal action follows Epic's December victory against Google in a separate antitrust case. Epic recently launched its own mobile app store, which it claims faces unfair obstacles due to Auto Blocker.

Mars' Long-Lost Atmosphere Might Be Hiding in Plain Sight

Slashdot - Mon, 2024-09-30 13:34
Newsweek writes that the missing atmosphere of Mars "may be locked up in the planet's clay-rich surface, a new study by MIT geologists has suggested." According to the researchers, ancient water trickling through Mars' rocks could have triggered a series of chemical reactions, converting CO2 into methane and trapping the carbon in clay minerals for billions of years... The dominant explanation relies on an interaction between the sun's rays and gases in the atmosphere. Mars lost its protective magnetic field billions of years ago, likely allowing high-energy solar particles to strike the upper atmosphere, kicking molecules off into space, according to NASA... But this might not be the whole story. The researchers focused on a type of clay mineral called smectite, known for its ability to trap carbon. These minerals, abundant on Mars, contain tiny folds that can store carbon molecules for aeons. The study was published in the journal Science Advances. "There is plenty of evidence for a thick clay layer on the Martian surface. Almost 80 percent of satellite spectra detect these high-surface-area clay minerals on the Martian surface. Clay has been detected in craters as deep as 17 kilometers [10.5 miles]," [lead author Joshua] Murray said... Their model suggested that Mars' surface could contain up to 1.7 bar of CO2 — roughly 80 percent of its early atmospheric volume — sequestered as methane within clay deposits. This methane could still be present today, lying beneath the planet's dry and barren crust. "We know this process happens, and it is well-documented on Earth. And these rocks and clays exist on Mars," Oliver Jagoutz, the study's author, said in a statement. "So, we wanted to try and connect the dots." The discovery that Mars' ancient atmosphere could be hidden within its surface clays offers a new perspective on the planet's history and raises intriguing possibilities for future exploration. For example, if the sequestered carbon could be recovered and converted, it could serve as a propellant for future space missions between Earth, Mars and beyond. "In some ways, Mars' missing atmosphere could be hiding in plain sight," says the study's lead author — and the article adds that this raises some interesting possibilities. "For example, if the sequestered carbon could be recovered and converted, it could serve as a propellant for future space missions between Earth, Mars and beyond..."

Exxon Mobil's 'Advanced' Technique for Recycling Plastic? Burning It

Slashdot - Mon, 2024-09-30 09:34
An anonymous reader shared this report from the Los Angeles Times: In recent years — as longstanding efforts to recycle plastics have faltered — Exxon Mobil has touted advanced recycling as a groundbreaking technology that will turn the tide on the plastic crisis. But despite its seemingly eco-friendly name, the attorney general's lawsuit denounced advanced recycling as a "public relations stunt" that largely involves superheating plastics to convert them into fuel. At Exxon Mobil's only "advanced recycling" facility in Baytown, Texas, only 8% of plastic is remade into new material, while the remaining 92% is processed into fuel that is later burned. [California attorney general Rob] Bonta's lawsuit seeks a court order to prohibit the company from describing the practice as "advanced recycling," arguing the vast majority of plastic is destroyed. Many environmental advocates and policy experts lauded the legal action as a major step toward ending greenwashing by Exxon Mobil — the world's largest producer of single-use plastic polymer... Advanced recycling, which is also called chemical recycling, is an umbrella term that typically involves heating or dissolving plastic waste to create fuel, chemicals and waxes — a fraction of which can be used to remake plastic. The most common techniques yield only 1% to 14% of the plastic waste, according to a 2023 study by the National Renewable Energy Laboratory. Exxon Mobil has largely used reclaimed plastic for fuel production while ramping up its virgin plastic production, according to Bonta. The executive director of California Communities Against Toxics complains Exxon Mobil's "advanced" recycling is "the same technology we've had since the Industrial Revolution... a blast furnace." (The article also quotes her as asking "How is that better than coal?") And a UCLA researcher who studied the issue blames misperceptions about plastic recycling on "an industry-backed misinformation campaign." He agrees that the reality is "having to burn more oil to turn that plastic back into oil, which you then burn." California's attorney general "alleges Exxon Mobil has had a patent for this technology since 1978, and the company is falsely rebranding it as 'new' and 'advanced'... It recently reemerged after the company learned that the term 'advanced recycling' resonated with members of the public..."

Could Atom-Sized Black Holes Be Detected in Our Solar System?

Slashdot - Mon, 2024-09-30 05:39
Scientific American has surprising news about the possibility of black holes the size of an atom but containing the mass of an asteroid — the so-called "primordial black holes" formed after the birth of the universe which could solve the ongoing mystery of the missing dark matter. These atom-sized black holes "may fly through the inner solar system about once a decade, scientists say... And if they sneak by the moon or Mars, scientists should be able to detect them, a new study shows." If one of these black holes comes near a planet or large moon, it should push the body off course enough to be measurable by current instruments. "As it passes by, the planet starts to wobble," says Sarah R. Geller, a theoretical physicist now at the University of California, Santa Cruz, and co-author of the study, which was published on September 17 in Physical Review D. "The wobble will grow over a few years but eventually it will damp out and go back to zero." Study team member Tung X. Tran, then an undergraduate student at the Massachusetts Institute of Technology, built a computer model of the solar system to see how the distance between Earth and nearby solar system objects would change after a black hole flyby. He found that such an effect would be most noticeable for Mars, whose distance scientists know within about 10 centimeters. For a black hole in the middle of the mass range, "we found that after three years the signal would grow to between one to three meters," Tran says. "That's way above the threshold of precision that we can measure." The Earth-Mars distance is particularly well tracked because scientists have been sending generations of probes and landers to the Red Planet... In a coincidence, an independent team published a paper about its search for signs of primordial black holes flying near Earth in the same issue of Physical Review D. The researchers' simulations found that such signals could be detectable in orbital data from Global Navigation Satellite Systems, as well as gravimeters that measure variations in Earth's gravitational field. "For decades physicists thought dark matter was likely to take the form of so-called weakly interacting massive particles (WIMPs)," the article points out. "Yet generations of ever more sensitive experiments meant to find these particles have come up empty." California astrophysicist Kevork Abazajian tells the site that now in the scientific community, "Primordial black holes are really gaining popularity."

The Hot New Trend in Commercial Real Estate? Renting to Data Centers

Slashdot - Mon, 2024-09-30 01:24
U.S. real estate developers "are having a hard time keeping up with demand," reports the Los Angeles Times, "as businesses in search of secure spots for their servers rent nearly every square foot that becomes available..." Construction of new data centers is at "extraordinary levels" driven by "insatiable demand," a recent report on the industry by real estate brokerage JLL found. "Never in my career of 25 years in real estate have I seen demand like this on a global scale," said JLL real estate broker Darren Eades, who specializes in data centers... The biggest drivers are AI and cloud service providers that include some of the biggest names in tech, such as Amazon, Microsoft, Google and Oracle. With occupancy in conventional office buildings still down sharply following the impact of the COVID-19 pandemic and property values falling, data centers represent a rare ripe opportunity for real estate developers, who are pursuing opportunities in major markets like Los Angeles and less urban locales that are served by plentiful and preferably cheap power needed to run data centers. "If you can find a cluster of power to build a site, they'll come," Eades said of developers. Construction is taking place at an "extraordinary" pace nationwide and still not keeping up, the JLL data center report said. [Data center] "Vacancy declined to a record low of 3% at midyear due to insatiable demand and despite rampant construction." Development increased more than sevenfold in two years, with the pipeline of new projects leveling off in the first half of 2024, a potential signal that the U.S. power grid cannot support development at a faster pace. But when projects currently under construction or planned are complete, the U.S. colocation market, in which businesses rent space in a data center owned by another company for their servers and other computing hardware, will triple in size from current levels... Real estate investors and landlords are being drawn into the market because demand from tenants is high and they are likely to renew their leases after shouldering the costs of setting up data centers. "They invest in their space and in your space and they tend to stick around longer," said Mark Messana, president of Downtown Properties, which owns offices in Los Angeles and San Francisco. "As we all know, the office market is struggling a little bit, so it's nice to be able to have some data customers in the mix..." Power demand for computing is growing so intense that it threatens to strain the nation's electrical grid, sending users to remote locations where power is plentiful and preferably cheap. Data center developers are working in Alabama, the Dakotas and Indiana, "traditionally states that wouldn't have data centers," Eades said. The article includes "the mother of all data centers" in the western U.S. — a 30-story building where "thousands of miles of undersea fiber-optic cables disappear into an ordinary-looking office tower." Once a prestigious location for businesses, "The recent departure of a law firm that had been in the building more than 50 years cleared out five floors that will quickly be re-leased to data tenants, said Eades, who represents the landlord..." To retrofit the building for data centers, "two elevators were removed so the empty shafts could hold water pipes used to help keep the temperature cool enough for the heat-producing servers" — and developers are happy rents "can be double what they are at newer downtown office high-rises, according to real estate data provider CoStar... "By 2030, data centers could account for as much as 11% of U.S. power demand — up from 3% now, according to analysts at Goldman Sachs."

California's Governor Just Vetoed Its Controversial AI Bill

Slashdot - Sun, 2024-09-29 23:51
"California Governor Gavin Newsom has vetoed SB 1047, a high-profile bill that would have regulated the development of AI," reports TechCrunch. The bill "would have made companies that develop AI models liable for implementing safety protocols to prevent 'critical harms'." The rules would only have applied to models that cost at least $100 million and use 10^26 FLOPS (floating point operations, a measure of computation) during training. SB 1047 was opposed by many in Silicon Valley, including companies like OpenAI, high-profile technologists like Meta's chief AI scientist Yann LeCun, and even Democratic politicians such as U.S. Congressman Ro Khanna. That said, the bill had also been amended based on suggestions by AI company Anthropic and other opponents. In a statement about today's veto, Newsom said, "While well-intentioned, SB 1047 does not take into account whether an AI system is deployed in high-risk environments, involves critical decision-making or the use of sensitive data. Instead, the.." bill applies stringent standards to even the most basic functions — so long as a large system deploys it. I do not believe this is the best approach to protecting the public from real threats posed by the technology." "Over the past 30 days, Governor Newsom signed 17 bills covering the deployment and regulation of GenAI technology..." according to a statement from the governor's office, "cracking down on deepfakes, requiring AI watermarking, protecting children and workers, and combating AI-generated misinformation... The Newsom Administration will also immediately engage academia to convene labor stakeholders and the private sector to explore approaches to use GenAI technology in the workplace." In a separate statement the governor pointed out California " is home to 32 of the world's 50 leading Al companies," and warned that the bill "could give the public a false sense of security about controlling this fast-moving technology. Smaller, specialized models may emerge as equally or even more dangerous than the models targeted by SB 1047 — at the potential expense of curtailing the very innovation that fuels advancement in favor of the public good..." "While well-intentioned, SB 1047 does not take into account whether an AI system is deployed in high-risk environments, involves critical decision-making or the use of sensitive data.

New Flexible RISC-V Semiconductor Has Great Potential

Slashdot - Sun, 2024-09-29 21:38
"For the first time, scientists have created a flexible programmable chip that is not made of silicon..." reports IEEE Spectrum — opening new possibilities for implantable devices, on-skin computers, brain-machine interfaces, and soft robotics. U.K.-based Pragmatic Semiconductor produced an "ultralow-power" 32-bit microprocessor, according to the article, and "The microchip's open-source RISC-V architecture suggests it might cost less than a dollar..." This shows potential for inexpensive applications like wearable healthcare electronics and smart package labels, according to the chip's inventors: For example, "we can develop an ECG patch that has flexible electrodes attached to the chest and a flexible microprocessor connected to flexible electrodes to classify arrhythmia conditions by processing the ECG data from a patient," says Emre Ozer, senior director of processor development at Pragmatic, a flexible chip manufacturer in Cambridge, England. Detecting normal heart rhythms versus an arrhythmia "is a machine learning task that can run in software in the flexible microprocessor," he says... Pragmatic sought to create a flexible microchip that cost significantly less to make than a silicon processor. The new device, named Flex-RV, is a 32-bit microprocessor based on the metal-oxide semiconductor indium gallium zinc oxide (IGZO). Attempts to create flexible devices from silicon require special packaging for the brittle microchips to protect them from the mechanical stresses of bending and stretching. In contrast, pliable thin-film transistors made from IGZO can be made directly at low temperatures onto flexible plastics, leading to lower costs... "Our end goal is to democratize computing by developing a license-free microprocessor," Ozer says... Other processors have been built using flexible semiconductors, such as Pragmatic's 32-bit PlasticARM and an ultracheap microcontroller designed by engineers in Illinois. Unlike these earlier devices, Flex-RV is programmable and can run compiled programs written in high-level languages such as C. In addition, the open-source nature of RISC-V also let the researchers equip Flex-RV with a programmable machine learning hardware accelerator, enabling artificial intelligence applications. Each Flex-RV microprocessor has a 17.5 square millimeter core and roughly 12,600 logic gates. The research team found Flex-RV could run as fast as 60 kilohertz while consuming less than 6 milliwatts of power... The Pragmatic team found that Flex-RV could still execute programs correctly when bent to a curve with a radius of 3 millimeters. Performance varied between a 4.3 percent slowdown to a 2.3 percent speedup depending on the way it was bent.
