Z-Wave Long Range and its mile-long capabilities will arrive next year
Z-Wave can be a very robust automation network, free from the complications and fragility of Wi-Fi and Bluetooth. Just how robust, you ask? More than a mile long, under the right circumstances, as hardware soon to hit the market promises.
All claims of radio distances should be taken with amounts of salt unhealthy for consumption. What can be accomplished across an empty field is not the same as what can be done through buildings, interference, and scatter. But Z-Wave Long Range (or Z-Wave LR), operating "in long range mode at full power," can hit 1.5 miles, according to the Z-Wave Alliance, presuming you've got the right star-shaped hub network.
By using a star network topology instead of a more traditional mesh, Z-Wave LR reduces the need for hubs and repeaters, relying instead on a central hub. It can be more reliable for larger commercial spaces, security setups, and bigger homes, and also more power efficient. Devices automatically adjust their signal strength while on Z-Wave networks, extending the battery life of a single coin cell up to 10 years—again, under best-case circumstances. If you're really a glutton for punishment, you can fit up to 4,000 devices on a network running Z-Wave LR, because LR can co-exist on the same network as standard Z-Wave meshes.

The $700 price tag isn’t hurting PS5 Pro’s early sales
When Sony revealed the PlayStation 5 Pro a few months ago, some wondered just how many people would be willing to spend $700 for a marginal upgrade to the already quite powerful graphical performance of the PS5. Now, initial sales reports suggest there's still a substantial portion of the console market that's willing to shell out serious money for top-of-the-line console graphics.
Circana analyst Matt Piscatella shared on Bluesky this morning that the PS5 Pro accounted for a full 19 percent of US PS5 sales in its launch month of November. That sales ratio puts initial upgrade interest in the PS5 Pro roughly in line with lifetime interest in the PS4 Pro, which recent reports suggest was responsible for about 20 percent of all PS4 sales following its launch in 2016.
That US sales ratio also lines up with international sales reports for the PS5 Pro launch. In the UK, GfK ChartTrack reports that the PS5 Pro was responsible for 26 percent of all console sales for November. And in Japan, Famitsu sales data suggests the PS5 Pro was responsible for a full 63 percent of the PS5's November sales after selling an impressive 78,000 units in its launch week alone.

EPA lets California set its own stricter emissions standards until 2035
Today, the US Environmental Protection Agency granted a pair of waivers to California, allowing the Golden State to continue regulating vehicle-caused air pollution within its borders. The first is for the California Air Resources Board's Advanced Clean Cars II regulations, which apply to light- and medium-duty vehicles like passenger cars, SUVs, and smaller trucks. The second waiver is for regulations that control the amount of nitrogen oxides (NOx) that can be emitted by heavy-duty vehicles as well as off-road vehicles.
The Clean Air Act allows states to apply for a waiver from the EPA to set their own emissions standards in cases where the federal regulations are insufficient to prevent deleterious pollution. The state applied for the latest waivers late in 2023, and after a public comment period and then a review by the agency, the EPA decided to approve them.
"California has longstanding authority to request waivers from EPA to protect its residents from dangerous air pollution coming from mobile sources like cars and trucks," said EPA Administrator Michael Regan. "Today's actions follow through on EPA's commitment to partner with states to reduce emissions and act on the threat of climate change."

GM and ChargePoint will deploy hundreds of “Omni Port” chargers in 2025
General Motors might have scaled back its electric vehicle ambitions in favor of more hybrids, but it's still accelerating its plans to build out EV charging infrastructure. Today, together with ChargePoint, GM revealed that it will deploy "hundreds" of new DC fast chargers under the GM Energy brand in 2025.
"The transition to electric mobility continues to be driven by leaders such as General Motors offering innovative EVs and committing to make chargers as ubiquitous as possible," said Rick Wilmer, CEO of ChargePoint. "Our collaboration with GM represents a significant investment in the infrastructure to enable fast and easy charging for all. Together, ChargePoint and GM will deliver a seamless fast charging experience via reliable charging hardware managed by our industry-leading software platform."
Many (but not all) of the new chargers will be capable of delivering up to 500 kW, a higher power level than any EV currently on the market is able to charge. Many of the chargers will also feature ChargePoint's "Omni Port," which has both CCS1 and NACS (J3400) plugs, allowing almost all EV drivers to make use of them. (Sorry, Nissan Leaf owners.)

Reminder: Donate to win swag in our annual Charity Drive sweepstakes
If you've been too busy fixing your video drivers to take part in this year's Ars Technica Charity Drive sweepstakes, don't worry. You still have time to donate to a good cause and get a chance to win your share of over $4,000 worth of swag (no purchase necessary to win).
In the first week or so of the drive, nearly 180 readers have contributed almost $16,000 to either the Electronic Frontier Foundation or Child's Play as part of the charity drive (Child's Play is barely hanging on to a small donation lead at the moment). That's a long way off from 2020's record haul of over $58,000, but there's still plenty of time until the Charity Drive wraps up on Thursday, January 2, 2025.
That doesn't mean you should put your donation off, though. Do yourself and the charities involved a favor and give now while you're thinking about it.

Who needs the dark web? Drug sales flourish on social media
For every illegal drug, there is a combination of emojis that dealers and consumers use to evade detection on social media and messaging platforms. Snowflakes, snowfall, and snowmen symbolize cocaine. Love hearts, lightning bolts, and pill capsules mean MDMA, or molly. Brown hearts and dragons represent heroin. Grapes and baby bottles are the calling cards for codeine-containing cough syrup, or lean. The humble maple leaf, meanwhile, is the universal symbol for all drugs.
The proliferation of open drug dealing on Instagram, Snapchat, and X—as well as on encrypted messaging platforms Telegram and WhatsApp—has transformed the fabric of illegal substance procurement, gradually making it more convenient, and arguably safer, for consumers, who can receive packages in the mail without meeting people on street corners or going through the rigmarole of the dark web. There is no reliable way to gauge drug trafficking on social media, but the European Union Drugs Agency acknowledged in its latest report on the drivers of European drug sales that purchases brokered through such platforms “appear to be gaining in prominence.”
Initial studies into drug sales on social media began to be published in 2012. Over the next decade, piecemeal studies began to reveal a notable portion of drug sales were being mediated by social platforms. In 2021, it was estimated some 20 percent of drug purchases in Ireland were being arranged through social media. In the US in 2018 and Spain in 2019, a tenth of young people who used drugs appear to have connected with dealers through the internet, with the large majority doing so through social media, according to one small study.

Russian space chief says country will fly on space station until 2030
In a wide-ranging interview with a Russian television station, the chief executive of Russia's main space corporation said the country is now planning to participate in the International Space Station project all the way to NASA's desired goal of 2030.
"In coordination with our American colleagues, we plan to de-orbit the station sometime around the beginning of 2030," the country's chief space official, Yuri Borisov, said during the interview. "The final scenario will probably be specified after the transition to a new NASA administration."
While the documents for such an extension have not been signed, these comments appear to represent a change in tone from Russia. When he first became head of Roscosmos in 2022, Borisov said Russia would leave the station partnership "after" 2024, which was interpreted as shortly thereafter. Later, Russia committed to working with NASA to keep the orbital outpost flying only through 2028. The US space agency has expressed a consistent desire to keep flying the station until 2030, after which point it hopes that private space station operators can provide one or more replacement facilities.

These squirrels are cold-blooded vole killers
They seem so sweet and innocent but these squirrels are also opportunistic killers.
We think of squirrels as adorably harmless creatures, admiring their bushy tails and twitchy little noses and the way they cram their cheeks with nuts or seeds to bring back to their nests for later. But the rodents turn out to be a bit more bloodthirsty than we thought. According to a new paper published in the Journal of Ethology, California ground squirrels have been caught in the act—many times over—of chasing, killing, and eating voles.
Co-author Jennifer Smith, a biologist at the University of Wisconsin, Eau Claire, described the behavior as "shocking," given the sheer number of times they watched squirrels do this. “We had never seen this behavior before," she said. "Squirrels are one of the most familiar animals to people. We see them right outside our windows; we interact with them regularly. Yet here’s this never-before-encountered-in-science behavior that sheds light on the fact that there’s so much more to learn about the natural history of the world around us.”
Squirrels mainly consume acorns, seeds, nuts, and fruits, but they have been known to supplement that diet with insects and, occasionally, by stealing eggs or young hatchlings from nests. And back in 1993, biologist J.R Callahan caused a stir by reporting that as many as 30 species of squirrel could be preying on smaller creatures: namely, fish, amphibians, reptiles, birds, and the occasional small mammal.

Report: Elon Musk failed to report movement required by security clearance
A new investigation from The New York Times suggests that SpaceX founder Elon Musk has not been reporting his travel activities and other information to the Department of Defense as required by his top-secret clearance.
According to the newspaper, concerns about Musk's reporting practices have led to reviews by three different bodies within the military; the Air Force, the Office of the Under Secretary of Defense for Intelligence and Security, and the Defense Department Office of Inspector General.
However, none of the federal agencies cited in the Times article has accused Musk of disclosing classified material.

“Unprecedented” decline in teen drug use continues, surprising experts
Teen drug use continued to fall in 2024, extending a dramatic decline spurred by the COVID-19 pandemic that experts expected would reverse now that the acute phase of the global crisis is well over.
But, according to data released Tuesday, the number of eighth, 10th, and 12th graders who collectively abstained from the use of alcohol, marijuana, or nicotine hit a new high this year. Use of illicit drugs also fell on the whole and use of non-heroin narcotics (Vicodin, OxyContin, Percocet) hit an all-time low.
"Many experts in the field had anticipated that drug use would resurge as the pandemic receded and social distancing restrictions were lifted," Richard Miech, team lead of the Monitoring the Future survey at the University of Michigan, said in a statement. "As it turns out, the declines have not only lasted but have dropped further."

Nvidia’s new app is causing large frame rate dips in many games
When Nvidia replaced the longstanding GeForce Experience App with a new, unified Nvidia App last month, most GPU owners probably noted the refresh and rebranding with nothing more than bemusement (though the new lack of an account login requirement was a nice improvement). Now, testing shows that running the new app with default settings can lead to some significant frame rate dips on many high-end games, even when the app's advanced AI features aren't being actively used.
Tom's Hardware noted the performance dip after reading reports of related problems around the web. The site's testing with and without the Nvidia App installed confirms that, across five games running on an RTX 4060, the app reduced average frame rates by around 3 to 6 percent, depending on the resolution and graphical quality level.
The site's measured frame rate drop peaked at 12 percent for Assassin's Creed Mirage running at 1080p Ultra settings; other tested games (including Baldur's Gate 3, Black Myth: Wukong, Flight Simulator 2024, and Stalker 2) showed a smaller drop at most settings.

After decades of talk, Seagate seems ready to actually drop the HAMR hard drives
How do you fit 32 terabytes of storage into a hard drive? With a HAMR.
Seagate has been experimenting with heat-assisted magnetic recording, or HAMR, since at least 2002. The firm has occasionally popped up to offer a demonstration or make yet another "around the corner" pronouncement. The press has enjoyed myriad chances to celebrate the wordplay of Stanley Kirk Burrell, but new qualification from large-scale customers might mean HAMR drives will be actually available, to buy, as physical objects, for anyone who can afford the most magnetic space possible. Third decade's the charm, perhaps.
HAMR works on the principle that, when heated, a disk's magnetic materials can hold more data in smaller spaces, such that you can fit more overall data on the drive. It's not just putting a tiny hot plate inside an HDD chassis; as Seagate explains in its technical paper, "the entire process—heating, writing, and cooling—takes less than 1 nanosecond." Getting from a physics concept to an actual drive involved adding a laser diode to the drive head, optical steering, firmware alterations, and "a million other little things that engineers spent countless hours developing." Seagate has a lot more about Mozaic 3+ on its site.

Companies issuing RTO mandates “lose their best talent”: Study
Return-to-office (RTO) mandates have caused companies to lose some of their best workers, a study tracking over 3 million workers at 54 "high-tech and financial" firms at the S&P 500 index has found. These companies also have greater challenges finding new talent, the report concluded.
The paper, Return-to-Office Mandates and Brain Drain [PDF], comes from researchers from the University of Pittsburgh, as well as Baylor University, The Chinese University of Hong Kong, and Cheung Kong Graduate School of Business. The study, which was published in November, spotted this month by human resources publication HR Dive, and cites Ars Technica reporting, was conducted by collecting information on RTO announcements and sourcing data from LinkedIn. The researchers said they only examined companies with data available for at least two quarters before and after they issued RTO mandates. The researchers explained:
To collect employee turnover data, we follow prior literature ... and obtain the employment history information of over 3 million employees of the 54 RTO firms from Revelio Labs, a leading data provider that extracts information from employee LinkedIn profiles. We manually identify employees who left a firm during each period, then calculate the firm’s turnover rate by dividing the number of departing employees by the total employee headcount at the beginning of the period. We also obtain information about employees’ gender, seniority, and the number of skills listed on their individual LinkedIn profiles, which serves as a proxy for employees’ skill level.
There are limits to the study, however. The researchers noted that the study "cannot draw causal inferences based on our setting." Further, smaller firms and firms outside of the high-tech and financial industries may show different results. Although not mentioned in the report, relying on data from a social media platform could also yield inaccuracies, and the number of skills listed on a LinkedIn profile may not accurately depict a worker's skill level.

OpenAI’s API users get full access to the new o1 model
Application developers who access OpenAI through its long-running API will now have access to the company's latest full o1 model, rather than the months-old o1-preview. The upgrade is one of a number of new features being rolled out to OpenAI's developer customers starting today.
OpenAI announced during a livestream today that the new o1 model would bring back many of the "core features you've been missing" from the API during o1-preview. This includes the ability to use developer messages to help guide your particular chatbot (i.e. "You are a helpful assistant for tax professionals.") and access to a "reasoning effort" parameter that tells the API how long to think about specific queries, saving time and money on simple problems so they can be used on the tougher ones. API users can also use visual information like scans of documents as input.
OpenAI also highlighted improvements to the new API's use of internal function calling, where the OpenAI model decides to call functions pre-written by outside developers to generate answers to certain queries, when appropriate. The new API is also more accurate in its use of structured outputs, which use a JSON schema to present information in a specific format outlined by the developer, OpenAI said.

Nvidia partners leak next-gen RTX 50-series GPUs, including a 32GB 5090
Rumors have suggested that Nvidia will be taking the wraps off of some next-generation RTX 50-series graphics cards at CES in January. And as we get closer to that date, Nvidia's partners and some of the PC makers have begun to inadvertently leak details of the cards.
According to recent leaks from both Zotac and Acer, it looks like Nvidia is planning to announce four new GPUs next month, all at the high end of its lineup: The RTX 5090, RTX 5080, RTX 5070 Ti, and RTX 5070 were all briefly listed on Zotac's website, as spotted by VideoCardz. There's also an RTX 5090D variant for the Chinese market, which will presumably have its specs tweaked to conform with current US export restrictions on high-performance GPUs.
Though the website leak didn't confirm many specs, it did list the RTX 5090 as including 32GB of GDDR7, an upgrade from the 4090's 24GB of GDDR6X. An Acer spec sheet for new Predator Orion desktops also lists 32GB of GDDR7 for the 4090, as well as 16GB of GDDR7 for the RTX 5080. This is the same amount of RAM included with the RTX 4080 and 4080 Super.

Big loss for ISPs as Supreme Court won’t hear challenge to $15 broadband law
The Supreme Court yesterday rejected the broadband industry's challenge to a New York law that requires Internet providers to offer $15- or $20-per-month service to people with low incomes.
In August, six trade groups representing the cable, telecom, mobile, and satellite industries filed a petition asking the Supreme Court to overturn an appeals court ruling that upheld the state law. But the Supreme Court won't take up the case. The high court denied the telecom groups' petition without comment in a list of orders released yesterday.
Although a US District Court judge blocked the law in 2021, that judge's ruling was reversed by the US Court of Appeals for the 2nd Circuit in April 2024. The Supreme Court's denial of the industry petition leaves the 2nd Circuit ruling in place.

Facing ban next month, TikTok begs SCOTUS for help
TikTok has asked the Supreme Court to step in before it's forced to shut down the app in the US next month.
In a petition requesting a temporary injunction, TikTok prompted the Supreme Court to block the ban and grant a review that TikTok believes will result in a verdict that the Protecting Americans from Foreign Adversary Controlled Applications Act is unconstitutional. And if the court cannot take up this review before TikTok's suggested January 6 deadline, the court should issue an administrative injunction delaying the ban until after Trump's inauguration, TikTok argued, appearing to seek any path to delay enforcement, even if only by a day.
According to TikTok, it makes no sense to force the app to shut down on January 19 if, the very next day or soon thereafter, Trump will take office and pause or otherwise intervene with enforcement.

Here’s the new hybrid Honda Prelude, on sale late 2025
The fact that Honda was working on a new Prelude coupe was not entirely secret—not after the automaker unveiled a show car at this year's Long Beach Grand Prix. This morning, the Japanese automaker confirmed that the new Prelude will go on sale here in the US late in 2025.
"The return of the Honda Prelude as a hybrid-electric sports model demonstrates our continued commitment to offer a variety of exhilarating products to meet the needs of our customers," said Jessika Laudermilk, assistant vice president of Honda Auto Sales. "The first three products in the Honda lineup in the 1970s were Civic, Accord, and Prelude, and soon all three will be back together again in our passenger car lineup as hybrids."
Honda has often used the two-door Prelude coupe as a testbed for new technologies, including torque vectoring and four-wheel steering, and was praised by the late automotive writer LJK Setright, who owned several Preludes across the years.

Trump FCC chair wants to revoke broadcast licenses—the 1st Amendment might stop him
President-elect Donald Trump's pick to lead the Federal Communications Commission, Brendan Carr, wants the FCC to crack down on news broadcasters that he perceives as being unfair to Trump or Republicans in general.
Carr's stated goals would appear to mark a major shift in the FCC's approach to broadcasters. Carr's predecessors, including outgoing Chairwoman Jessica Rosenworcel and Republican Ajit Pai, who served in the first Trump administration, both rejected Trump's calls to punish news networks for alleged bias.
Carr has instead embraced Trump's view that broadcasters should be punished for supposed anti-conservative bias. Carr has threatened to revoke licenses by wielding the FCC's authority to ensure that broadcast stations using public airwaves operate in the public interest, despite previous chairs saying the First Amendment prevents the FCC from revoking licenses based on content.

China orbits first Guowang Internet satellites, with thousands more to come
The first batch of Internet satellites for China's Guowang megaconstellation launched Monday on the country's heavy-lift Long March 5B rocket.
The satellites are the first of up to 13,000 spacecraft a consortium of Chinese companies plans to build and launch over the next decade. The Guowang fleet will beam low-latency high-speed Internet signals in an architecture similar to SpaceX's Starlink network, although Chinese officials haven't laid out any specifics, such as target markets, service specifications, or user terminals.
The Long March 5B rocket took off from Wenchang Space Launch Site on Hainan Island, China's southernmost province, at 5:00 am EST (10:00 UTC) Monday. Ten liquid-fueled engines powered the rocket off the ground with 2.4 million pounds of thrust, steering the Long March 5B on a course south from Wenchang into a polar orbit.
