AT&T Goes Up Against T-Mobile, Starlink With AST SpaceMobile Satellite Deal

Slashdot.org - Thu, 05/16/2024 - 05:00
Michael Kan reports via PCMag: AT&T has struck a deal to bring satellite internet connectivity to phones through AST SpaceMobile, a potential rival to SpaceX's Starlink. AT&T says the commercial agreement will last until 2030. The goal is "to provide a space-based broadband network to everyday cell phones," a spokesperson tells PCMag, meaning customers can receive a cellular signal in remote areas where traditional cell towers are few and far between. All they'll need to do is ensure their phone has a clear view of the sky. AT&T has been working with Texas-based AST SpaceMobile since 2018 on the technology, which involves using satellites in space as orbiting cell towers. In January, AT&T was one of several companies (including Google) to invest $110 million in AST. In addition, the carrier created a commercial starring actor Ben Stiller to showcase AST's technology. In today's announcement, AT&T notes that "previously, the companies were working together under a Memorandum of Understanding," which is usually nonbinding. Hence, the new commercial deal suggests AT&T is confident AST can deliver fast and reliable satellite internet service to consumer smartphones -- even though it hasn't launched a production satellite. AST has only launched one prototype satellite; in tests last year, it delivered download rates at 14Mbps and powered a 5G voice call. Following a supply chain-related delay, the company is now preparing to launch its first batch of "BlueBird" production satellites later this year, possibly in Q3. In Wednesday's announcement, AT&T adds: "This summer, AST SpaceMobile plans to deliver its first commercial satellites to Cape Canaveral for launch into low Earth orbit. These initial five satellites will help enable commercial service that was previously demonstrated with several key milestones." Still, AST needs to launch 45 to 60 BlueBird satellites before it can offer continuous coverage in the U.S., although in an earnings call, the company said it'll still be able to offer "non-continuous coverage" across 5,600 cells in the country.

Morningstar Asset Class Correlation Charts 2024: 20-Year Historical Matrix

MyMoneyBlog.com - Thu, 05/16/2024 - 03:44

Morningstar has published their 2024 Diversification Landscape Update (direct link to PDF), another useful whitepaper for DIY investors that looks closer at the correlations between different asset classes. In their Key Takeaways, they note the quick turnaround from “The Classic 60/40 Portfolio is Dead” articles at the end of 2022 to “The Classic 60/40 Portfolio is Back!” at the end of 2023.

After a dismal year in 2022, the plain-vanilla version of a 60/40 portfolio (made up of US stocks and US investment-grade bonds) gained about 18% in 2023. Diversifying into other asset classes generally led to lower returns.

This marks a reversal from 2022 when portfolio diversification was a net positive. However, the basic 60/40 portfolio, composed of US stocks and high-quality bonds, has been tough to beat over longer periods. A 60/40 portfolio improved risk-adjusted returns versus an all-stock benchmark in more than 87% of the rolling three-year periods starting in 1976.

A potential benefit from owning multiple asset classes is that the lower the correlation between asset classes (the less they move in the same direction), the greater the reduction in volatility you get by combining assets. As long as you combine asset classes with correlations below 1 (perfectly correlated), you get some degree of volatility reduction. (See top graphic.) You can also see that the volatility reduction benefit mostly occurs within the first few asset classes; you don’t need 10 of them.

As you can see from the 60/40 Key Takeaway, the catch here is that correlations aren’t always stable. We have to look for longer historical trends with evidence that it will continue. Here are a few selected charts from the research paper.

T-Bill and Chill. Over long periods, US Treasury bonds have a lower average correlation to US stocks than a Total Bond index that includes investment-grade corporate bonds. But T-Bills (cash) get rid of the interest rate risk within T-Bonds as well, which often results in T-Bills being the most reliable shelter from the storm. You might not get a handy negative correlation boost during a stock crash, but the correlation will be reliably close to zero and your principal will be ready and waiting to deploy.

International stocks offer a small diversification benefit, but are usually strongly correlated with US stocks. (Though a little less so recently.) In the end, you must have faith that international stock returns will at times exceed US stock returns for periods of time to invest in this asset class. That faith has been tested recently, but I still would rather own them than not.

Commodities and Gold. Commodities go through boom and bust cycles as part of their nature, and the correlations with US stocks can also stay high or low for years at a time. I find it all very unreliable and unpredictable. Now, Gold has shown a consistently low correlation with US stocks, which is definitely an attractive quality. I’m more concerned about the long-term returns. Again, you need to have faith that long-term average gold returns will be well above inflation.

Long-term average correlations between asset classes. At the bottom of the whitepaper, don’t miss the charts which include correlation matrixes between major asset classes over the last 1, 3, 5, 10, 15, and 20 years.

Microsoft's AI Push Imperils Climate Goal As Carbon Emissions Jump 30%

Slashdot.org - Thu, 05/16/2024 - 02:00
Microsoft's ambitious goal to be carbon negative by 2030 is threatened by its expanding AI operations, which have increased its carbon footprint by 30% since 2020. To meet its targets, Microsoft must quickly adopt green technologies and improve efficiency in its data centers, which are critical for AI but heavily reliant on carbon-intensive resources. Bloomberg reports: Now to meet its goals, the software giant will have to make serious progress very quickly in gaining access to green steel and concrete and less carbon-intensive chips, said Brad Smith, president of Microsoft, in an exclusive interview with Bloomberg Green. "In 2020, we unveiled what we called our carbon moonshot. That was before the explosion in artificial intelligence," he said. "So in many ways the moon is five times as far away as it was in 2020, if you just think of our own forecast for the expansion of AI and its electrical needs." [...] Despite AI's ravenous energy consumption, this actually contributes little to Microsoft's hike in emissions -- at least on paper. That's because the company says in its sustainability report that it's 100% powered by renewables. Companies use a range of mechanisms to make such claims, which vary widely in terms of credibility. Some firms enter into long-term power purchase agreements (PPAs) with renewable developers, where they shoulder some of a new energy plant's risk and help get new solar and wind farms online. In other cases, companies buy renewable energy credits (RECs) to claim they're using green power, but these inexpensive credits do little to spur new demand for green energy, researchers have consistently found. Microsoft uses a mix of both approaches. On one hand, it's one of the biggest corporate participants in power purchase agreements, according to BloombergNEF, which tracks these deals. But it's also a huge purchaser of RECs, using these instruments to claim about half of its energy use is clean, according to its environmental filings in 2022. By using a large quantity of RECs, Microsoft is essentially masking an even larger growth in emissions. "It is Microsoft's plan to phase out the use of unbundled RECs in future years," a spokesperson for the company said. "We are focused on PPAs as a primary strategy." So what else can be done? Smith, along with Microsoft's Chief Sustainability Officer Melanie Nakagawa, has laid out clear steps in the sustainability report. High among them is to increase efficiency, which is to use the same amount of energy or computing to do more work. That could help reduce the need for data centers, which will reduce emissions and electricity use. On most things, "our climate goals require that we spend money," said Smith. "But efficiency gains will actually enable us to save money." Microsoft has also been at the forefront of buying sustainable aviation fuels that has helped reduce some of its emissions from business travel. The company also wants to partner with those who will "accelerate breakthroughs" to make greener steel, concrete and fuels. Those technologies are starting to work at a small scale, but remain far from being available in commercial quantities even if expensive. Cheap renewable power has helped make Microsoft's climate journey easier. But the tech giant's electricity consumption last year rivaled that of a small European country -- beating Slovenia easily. Smith said that one of the biggest bottlenecks for it to keep getting access to green power is the lack of transmission lines from where the power is generated to the data centers. That's why Microsoft says it's going to increase lobbying efforts to get governments to speed up building the grid. If Microsoft's emissions remain high going into 2030, Smith said the company may consider bulk purchases of carbon removal credits, even though it's not "the desired course." "You've got to be willing to invest and pay for it," said Smith. Climate change is "a problem that humanity created and that humanity can solve."

Wallet Recovery Firms Buzz as Locked-out Crypto Investors Panic in Bitcoin Boom

Slashdot.org - Thu, 05/16/2024 - 00:30
The recent surge in bitcoin prices has the phones at crypto wallet recovery firms ringing off the hook, as retail investors locked out of their digital vaults make frantic calls to regain access to their accounts. From a report: Cryptocurrencies exist on a decentralized digital ledger known as blockchain and investors may opt to access their holdings either through a locally stored software wallet or a hardware wallet, to avoid risks related to owning crypto with an exchange, as in the case of the former FTX. Losing access to a crypto wallet is a well-known problem. Investors forgetting their intricate passwords is a primary reason, but loss of access to two-factor authentication devices, unexpected shutdowns of cryptocurrency exchanges and cyberattacks are also common. Wallet passwords are usually alphanumeric and the wallet provider also offers a set of randomized words, known as "seed phrases," for additional security - both these are known only to the user. If investors lose the passwords and phrases, access to their wallets is cut off. With bitcoin prices regaining traction since last October and hitting a record high of $73,803.25 in March, investors seem to be suffering from a classic case of FOMO, or the fear of missing out. Reuters spoke to nearly a dozen retail investors who had lost access to their crypto wallets. Six of them contacted a recovery services firm and managed to regain access to their holdings.

MIT Students Stole $25 Million In Seconds By Exploiting ETH Blockchain Bug, DOJ Says

Slashdot.org - Wed, 05/15/2024 - 22:30
An anonymous reader quotes a report from Ars Technica: Within approximately 12 seconds, two highly educated brothers allegedly stole $25 million by tampering with the ethereum blockchain in a never-before-seen cryptocurrency scheme, according to an indictment that the US Department of Justice unsealed Wednesday. In a DOJ press release, US Attorney Damian Williams said the scheme was so sophisticated that it "calls the very integrity of the blockchain into question." "The brothers, who studied computer science and math at one of the most prestigious universities in the world, allegedly used their specialized skills and education to tamper with and manipulate the protocols relied upon by millions of ethereum users across the globe," Williams said. "And once they put their plan into action, their heist only took 12 seconds to complete." Anton, 24, and James Peraire-Bueno, 28, were arrested Tuesday, charged with conspiracy to commit wire fraud, wire fraud, and conspiracy to commit money laundering. Each brother faces "a maximum penalty of 20 years in prison for each count," the DOJ said. The indictment goes into detail explaining that the scheme allegedly worked by exploiting the ethereum blockchain in the moments after a transaction was conducted but before the transaction was added to the blockchain. To uncover the scheme, the special agent in charge, Thomas Fattorusso of the IRS Criminal Investigation (IRS-CI) New York Field Office, said that investigators "simply followed the money." "Regardless of the complexity of the case, we continue to lead the effort in financial criminal investigations with cutting-edge technology and good-ol'-fashioned investigative work, on and off the blockchain," Fattorusso said.

Bay Area City Orders Scientists To Stop Controversial Cloud Brightening Experiment

Slashdot.org - Wed, 05/15/2024 - 21:02
Last month, researchers from the University of Washington started conducting an experiment on a decommissioned naval ship in Alameda to test if spraying salt water into the air could brighten clouds and cool the planet. However, their project was forced to stop this month after the city got word of what was going on. SFGate reports: According to a city press release, scientists were ordered to halt the experiment because it violated Alameda's lease with the USS Hornet, the aircraft carrier from which researchers were spraying saltwater into the air using "a machine resembling a snowmaker." The news was first reported by the Alameda Post. "City staff are working with a team of biological and hazardous materials consultants to independently evaluate the health and environmental safety of this particular experiment," the press release states. Specifically, chemicals present in the experiment's aerosol spray are being evaluated to study whether or not they pose any threats to humans, animals or the environment. So far, there isn't any evidence that they do, the city stated. The prospect of a city-conducted review was not unexpected, the University of Washington said in a statement shared with SFGATE. "In fact, the CAARE (Coastal Aerosol Research and Engagement) facility is designed to help regulators, community members and others engage with the research closely, and we consider the current interactions with the city to be an integral part of that process," the statement reads. "We are happy to support their review and it has been a highly constructive process so far." The marine cloud brightening (MCB) technique involves spraying fine particles of sea salt into the atmosphere from ships or specialized machines. These sea salt particles are chosen because they are a natural source of cloud-forming aerosols and can increase the number of cloud droplets, making the clouds more reflective. The particles sprayed are extremely small, about 1/1000th the width of a human hair, ensuring they remain suspended in the air and interact with cloud droplets effectively. By reflecting more sunlight, these brightened clouds can reduce the amount of solar energy reaching the Earth's surface, leading to localized cooling. If implemented on a large scale, this cooling effect could potentially offset some of the warming caused by greenhouse gases. You can learn more about the experiment here.

Netflix To Take On Google and Amazon By Building Its Own Ad Server

Slashdot.org - Wed, 05/15/2024 - 20:25
Lauren Forristal writes via TechCrunch: Netflix announced during its Upfronts presentation on Wednesday that it's launching its own advertising technology platform only a year and a half after entering the ads business. This move pits it against other industry heavyweights with ad servers, like Google, Amazon and Comcast. The announcement signifies a significant shake-up in the streaming giant's advertising approach. The company originally partnered with Microsoft to develop its ad tech, letting Netflix enter the ad space quickly and catch up with rivals like Hulu, which has had its own ad server for over a decade. With the launch of its in-house ad tech, Netflix is poised to take full control of its advertising future. This strategic move will empower the company to create targeted and personalized ad experiences that resonate with its massive user base of 270 million subscribers. [...] Netflix didn't say exactly how its in-house solution will change the way ads are delivered, but it's likely it'll move away from generic advertisements. According to the Financial Times, Netflix wants to experiment with "episodic" campaigns, which involve a series of ads that tell a story rather than delivering repetitive ads. During the presentation, Netflix also noted that it'll expand its buying capabilities this summer, which will now include The Trade Desk, Google's Display & Video 360 and Magnite as partners. Notably, competitor Disney+ also has an advertising agreement with The Trade Desk. Netflix also touted the success of its ad-supported tier, reporting that 40 million global monthly active users opt for the plan. The ad tier had around 5 million users within six months of launching.

US Regulators Approve Rule That Could Speed Renewables

Slashdot.org - Wed, 05/15/2024 - 19:45
Longtime Slashdot reader necro81 writes: The U.S. Federal Energy Regulatory Commission (FERC), which controls interstate energy infrastructure, approved a rule Monday that should boost new transmission infrastructure and make it easier to connect renewable energy projects. (More coverage here, here, and here.) Some 11,000 projects totaling 2,600 GW of capacity are in planning, waiting to break ground, or connect to the grid. But they're stymied by the need for costly upgrades, or simply waiting for review. The frustrations are many. Each proposed project undergoes a lengthy grid-impact study and assessed the cost of necessary upgrades. Each project is considered in isolation, regardless of whether similar projects are happening nearby that could share the upgrade costs or auger different improvements. The planning process tends to be reactive -- examining only the applications in front of them -- rather than considering trends over the coming years. It's a first-come, first-served queue: if one project is ready to break ground, it must wait behind another project that's still securing funding or permitting. Two years in development, the dryly-named Improvements to Generator Interconnection Procedures and Agreements directs utility operators to plan infrastructure improvements with a 20-yr forecast of new energy sources and increased demand. Rather than examining each project in isolation, similar projects will be clustered and examined together. Instead of a First-Come, First-Served serial process, operators will instead examine First-Ready, allowing shovel-ready projects to jump the queue. The expectation is that these new rules will speed up and streamline the process of developing and connecting new energy projects through more holistic planning, penalties for delays, sensible cost-sharing for upgrades, and justification for long-term investments.
