Instagram users discover old AI-powered “characters,” instantly revile them

A little over a year ago, Meta created Facebook and Instagram profiles for "28 AIs with unique interests and personalities for you to interact with and dive deeper into your interests." Today, the last of those profiles is being taken down amid waves of viral revulsion as word of their existence has spread online.

The September 2023 launch of Meta's social profiles for AI characters was announced alongside a much splashier initiative that created animated AI chatbots with celebrity avatars at the same time. Those celebrity-based AI chatbots were unceremoniously scrapped less than a year later amid a widespread lack of interest.

But roughly a dozen of the unrelated AI character profiles still remained accessible as of this morning via social media pages labeled as "AI managed by Meta." Those profiles—which included a mix of AI-generated imagery and human-created content, according to Meta—also offered real users the ability to live chat with these AI characters via Instagram Direct or Facebook Messenger.

Rumors say next-gen RTX 50 GPUs will come with big jumps in power requirements

Nvidia is reportedly gearing up to launch the first few cards in its RTX 50-series at CES next week, including an RTX 5090, RTX 5080, RTX 5070 Ti, and RTX 5070. The 5090 will be of particular interest to performance-obsessed, money-is-no-object PC gaming fanatics since it's the first new GPU in over two years that can beat the performance of 2022's RTX 4090.

But boosted performance and slower advancements in chip manufacturing technology mean that the 5090's maximum power draw will far outstrip the 4090's, according to leakers. VideoCardz reports that the 5090's thermal design power (TDP) will be set at 575 W, up from 450 W for the already power-hungry RTX 4090. The RTX 5080's TDP is also increasing to 360 W, up from 320 W for the RTX 4080 Super.

That also puts the RTX 5090 close to the maximum power draw available over a single 12VHPWR connector, which is capable of delivering up to 600 W of power (though once you include the 75 W available via the PCI Express slot on your motherboard, the actual maximum possible power draw for a GPU with a single 12VHPWR connector is a slightly higher 675 W).

Marvel Rivals lifts 100-year “cheating” bans on Mac and Steam Deck players

With Valve's impressive work on the Proton tool for Linux and the Mac's Game Porting Toolkit and CrossOver options, few games are truly "Windows only" these days. The exceptions are those with aggressive, Windows-based anti-cheating tools baked in, something that hit back hard against players eager to dive into a new superhero shooter.

Marvel Rivals, an Overwatch-ish free-to-play hero shooter released in early December 2024, has all the typical big online game elements: an in-game shop with skins and customizations, battle passes, and anti-cheating tech. While Proton, which powers the Linux-based Steam Deck's ability to play just about any Windows game, has come very far in a few years' time, its biggest blind spots are these kinds of online-only games, like Grand Theft Auto OnlineFortniteDestiny 2, Apex Legendsand the like. The same goes for Mac players, who, if they can work past DirectX 12, can often get a Windows game working in CrossOver or Parallels, minus any anti-cheat tools.

Is there harm in trying? For a while, there was 100 years' worth. As detailed in the r/macgaming subreddit and at r/SteamDeck, many players who successfully got Marvel Rivals working would receive a "Penalty Issued" notice, with a violation "detected" and bans issued until 2124. Should such a ban stand, players risked entirely missing the much-prophesied Year of the Linux Desktop or Mainstream Mac Gaming, almost certain to happen at some point in that span.

Delve into the physics of the Hula-Hoop

High-speed video of experiments on a robotic hula hooper, whose hourglass form holds the hoop up and in place.

Some version of the Hula-Hoop has been around for millennia, but the popular plastic version was introduced by Wham-O in the 1950s and quickly became a fad. Now, researchers have taken a closer look at the underlying physics of the toy, revealing that certain body types are better at keeping the spinning hoops elevated than others, according to a new paper published in the Proceedings of the National Academy of Sciences.

“We were surprised that an activity as popular, fun, and healthy as hula hooping wasn’t understood even at a basic physics level,” said co-author Leif Ristroph of New York University. “As we made progress on the research, we realized that the math and physics involved are very subtle, and the knowledge gained could be useful in inspiring engineering innovations, harvesting energy from vibrations, and improving in robotic positioners and movers used in industrial processing and manufacturing.”

Ristroph's lab frequently addresses these kinds of colorful real-world puzzles. For instance, in 2018, Ristroph and colleagues fine-tuned the recipe for the perfect bubble based on experiments with soapy thin films. In 2021, the Ristroph lab looked into the formation processes underlying so-called "stone forests" common in certain regions of China and Madagascar.

The 2025 Honda Civic Hybrid: A refreshing alternative to a crossover

When Honda gave the 11th-generation Civic Hatchback a refresh late last year, among the changes were the addition of a hybrid option to the lineup. There was already a lot to like about Honda's compact, which eschews lamentable trends like an over-reliance on touchscreens for good old-fashioned physical controls. Now, a big efficiency boost makes it even more attractive.

The new powertrain is available in the $29,950 Sport Hybrid and the $32,950 Sport Touring Hybrid (the trim we tested). With an output of 200 hp (150 kW) and 232 lb-ft (315 Nm), it's both more powerful and torquier than the 1.5 L turbo previously found in the top trim Civics. And it uses a heck of a lot less fuel in the process.

The Civic uses a hybrid powertrain with two electric motors working with the 2.0 L, four-cylinder engine. One works as a generator to charge the 1 kWh traction battery from the engine under most conditions. The battery then powers the 181 hp (135 kW) traction motor, which is what mostly drives the front wheels, although like most other series hybrids of this nature, it operates as a parallel hybrid with the 141 hp (105 kW) gasoline engine directly driving the front wheels at highway cruising speeds, as that is actually more efficient. (For some reason, this supposed lack of engineering purity seems to really upset some people, who I am sure will let us know why in the comments.)

Elon Musk: “We’re going straight to Mars. The Moon is a distraction.”

Although SpaceX founder Elon Musk is known for outspokenness and controversial comments on his social media site X, he has been relatively restrained when it comes to US space policy in recent years.

For example, he has rarely criticized NASA or its overall goal to return humans to the Moon through the Artemis Program. Rather, Musk, who has long preferred Mars as a destination for humans, has more or less been a team player when it comes to the space agency's lunar-focused plans.

This is understandable from a financial perspective, as SpaceX has contracts worth billions of dollars to not only build a Human Landing System as part of NASA's Artemis Program but also to supply food, cargo, and other logistics services to a planned Lunar Gateway in orbit around the Moon.

Anthropic gives court authority to intervene if chatbot spits out song lyrics

On Thursday, music publishers got a small win in a copyright fight alleging that Anthropic's Claude chatbot regurgitates song lyrics without paying licensing fees to rights holders.

In an order, US district judge Eumi Lee outlined the terms of a deal reached between Anthropic and publisher plaintiffs who license some of the most popular songs on the planet, which she said resolves one aspect of the dispute.

Through the deal, Anthropic admitted no wrongdoing and agreed to maintain its current strong guardrails on its AI models and products throughout the litigation. These guardrails, Anthropic has repeatedly claimed in court filings, effectively work to prevent outputs containing actual song lyrics to hits like Beyonce's "Halo," Spice Girls' "Wannabe," Bob Dylan's "Like a Rolling Stone," or any of the 500 songs at the center of the suit.

Fast radio bursts originate near the surface of stars

When fast radio bursts (FRBs) were first detected in 2007, they were a complete enigma. As their name implies, these events involve a very brief eruption of radio emissions and then typically silence, though a few objects appear to be capable of sending out multiple bursts. By obtaining enough data from lots of individual bursts, researchers gradually put the focus on magnetars, versions of neutron stars that have intense magnetic fields.

But we still don't know whether a magnetar is a requirement for an FRB or if the events can be triggered by less magnetized neutron stars as well. And we have little hint of the mechanism that produces the burst itself. Bursts could potentially be produced by an event in the star's magnetic field itself, or the star could be launching some energetic material that subsequently produces an FRB at some distance from the star.

But now, a rare burst has provided indications that FRBs likely originate near the star and that they share a feature with the emissions of pulsars, another subtype of neutron star.

Time to check if you ran any of these 33 malicious Chrome extensions

3 January 2025 at 04:15

As many of us celebrated the year-end holidays, a small group of researchers worked overtime tracking a startling discovery: At least 33 browser extensions hosted in Google’s Chrome Web Store, some for as long as 18 months, were surreptitiously siphoning sensitive data from roughly 2.6 million devices.

The compromises came to light with the discovery by data loss prevention service Cyberhaven that a Chrome extension used by 400,000 of its customers had been updated with code that stole their sensitive data.

’Twas the night before Christmas

The malicious extension, available as version 24.10.4, was available for 31 hours, from December 25 at 1:32 AM UTC to Dec 26 at 2:50 AM UTC. Chrome browsers actively running Cyberhaven during that window would automatically download and install the malicious code. Cyberhaven responded by issuing version 24.10.5, and 24.10.6 a few days later.

Rocket Report: Avio named top European launch firm; New Glenn may launch soon

Welcome to Edition 7.25 of the Rocket Report! Happy New Year! It's a shorter edition of the newsletter this week because most companies (not named Blue Origin, this holiday season) took things easier over the last 10 days. But after the break we're back in the saddle for the new year, and eager to see what awaits us in the world of launch.

As always, we welcome reader submissions, and if you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

Avio lands atop list of European launch firms. You know it probably was not a great year for European rocket firms when the top-ranked company on the continent is Avio, which launched a grand total of two rockets in 2024. The Italian rocket firm earned this designation from European Spaceflight after successfully completing the final flight of the Vega rocket in September and returning the Vega C rocket to flight in December.

Appeals court blocks FCC’s efforts to bring back net neutrality rules

On Thursday, a three-judge panel struck down net neutrality rules that the Federal Communications Commission (FCC) had hoped would stop broadband providers from varying speeds for users when connecting to different websites.

In his opinion, US circuit judge Richard Allen Griffin wrote that the FCC lacked the authority to impose the net neutrality rules under the "telecommunications service" provision of the Communications Act.

"The core of the dispute here," Griffin wrote, "is whether Broadband Internet Service Providers" like Xfinity or Spectrum offer a "telecommunications service" or an "information service." Because judges agreed they offer the latter, the court ruled that they could not be subjected to the FCC's net neutrality policies.

Why Half-Life 3 speculation is reaching a fever pitch again

The more than two decades since Half-Life 2's release have been filled with plenty of rumors and hints about Half-Life 3, ranging from the official-ish to the thin to the downright misleading. As we head into 2025, though, we're approaching something close to a critical mass of rumors and leaks suggesting that Half-Life 3 is really in the works this time, and could be officially announced in the coming months.

The latest tease came just before the end of 2024 via a New Year's Eve social media video from G-Man voice actor Mike Shapiro. In the voice of the mysterious in-game bureaucrat, Shapiro expresses hopes that "the next quarter century [will] deliver as many unexpected surprises as did the millennium's first (emphasis added)... See you in the new year."

#Valve #Halflife #GMan #2025 pic.twitter.com/mdT5hlxKJT

— Mike Shapiro (@mikeshapiroland) December 31, 2024

The post is all the more notable because it's Shapiro's first in over four years, when he concluded a flurry of promotional posts surrounding the release of Half-Life: Alyx (many of which were in-character as G-Man). And in 2020, just after Alyx's release, Shapiro told USGamer that he had recently worked on a "blast from the past" project that he would "announce... on my Twitter feed when I'm allowed to" (no such announcement has been forthcoming for any other game).

Someone made a CAPTCHA where you play Doom on Nightmare difficulty

People have been complaining for a while that passing a CAPTCHA is too difficult, but developer and tech CEO Guillermo Rauch has made one of the hardest yet: a fully playable CAPTCHA based on the classic PC game Doom.

It's been a long-running joke that developers will make Doom run on absolutely anything, so it's not much of a surprise that it's now running inside something that resembles a CAPTCHA.

The app essentially amounts to a small Doom level that is playable with keyboard controls (arrow keys to move, space bar to shoot) within a CAPTCHA-like presentation. You must kill three enemies to pass the test.

USB-C gets a bit more universal as the EU’s mandate goes into effect

"It's time for THE charger," the European Commission posted to X on December 28, 2024. While the sentiment only applies to one continent (and not all of it) and only certain devices, the Common Charger Directive now in effect in the European Union suggests that far fewer gadgets will foist barrels, USB-micro, or proprietary plugs onto their owners.

The Common Charger Directive demands that a "USB-C receptacle" be equipped on "radio equipment" that is "equipped with a removable or embedded rechargeable battery" and "can be recharged via wired charging." If it has a battery and can be powered by up to 100 watts through a USB-C connection, it's generally subject to the EU's USB-C requirements. The directive applies to devices "placed on the market"—sent to a distributor or buyer—after December 28, even if they were initially designed and sold before that date.

Laptops get until April 2026 to comply, but most other things—phones, tablets, handheld gaming devices, computer accessories, and wireless headphones—will have to be powered by USB-C to be sold inside the EU from now on. Drones, for the time being, are largely unaddressed by the directive, but the EU will likely get around to them.

Siri “unintentionally” recorded private convos; Apple agrees to pay $95M

Apple has agreed to pay $95 million to settle a lawsuit alleging that its voice assistant Siri routinely recorded private conversations that were then shared with third parties and used for targeted ads.

In the proposed class-action settlement—which comes after five years of litigation—Apple admitted to no wrongdoing. Instead, the settlement refers to "unintentional" Siri activations that occurred after the "Hey, Siri" feature was introduced in 2014, where recordings were apparently prompted without users ever saying the trigger words, "Hey, Siri."

Sometimes Siri would be inadvertently activated, a whistleblower told The Guardian, when an Apple Watch was raised and speech was detected. The only clue that users seemingly had of Siri's alleged spying was eerily accurate targeted ads that appeared after they had just been talking about specific items like Air Jordans or brands like Olive Garden, Reuters noted (claims which remain disputed).

It’s January, which means another batch of copyrighted work is now public domain

It's January, and for people in the US, that means the same thing it's meant every January since 2019: a new batch of previously copyrighted works have entered the public domain. People can publish, modify, and adapt these works and their characters without needing to clear rights or pay royalties.

This year's introductions cover books, plays, movies, art, and musical compositions from 1929, plus sound recordings from 1924. Most works released from 1923 onward are protected for 95 years after their release under the terms of 1998's Sonny Bono Copyright Term Extension Act. This law prevented new works from entering the public domain for two decades.

As it does every year, the Duke University Center for the Study of the Public Domain has a rundown of the most significant works entering the public domain this year.

Samsung is the next company to try to popularize 3D displays (again)

Samsung is starting 2025 with a fresh attempt at popularizing 3D displays. Announced today, Samsung’s Odyssey 3D is the follow-up to prototypes that Samsung demoed at last year's CES technology trade show. This year, Samsung is showing off a final product, which is supposed to make 2D content look 3D.

Those who have dealt with 3D glasses may be relieved to hear that the Odyssey 3D doesn't require them. According to the South Korean company’s announcement, the monitor's use of a lenticular lens that is “attached to the front of the panel and its front stereo camera" means that you don't have to wear glasses to access the monitor's “customizable 3D experience.” Lenticular lenses direct different images to each eye to make images look three-dimensional. This is a notable advancement from the first 3D monitor that Samsung released in 2009. That display used Nvidia software and Nvidia shutter glasses to allow users to toggle between a 2D view and a 3D view through a few button presses and supported content.

Another advancement is the Odyssey 3D's claimed ability to use artificial intelligence “to analyze and convert 2D video into 3D.” We’ve recently seen similar technology from brands like Acer, which announced portable monitors in 2022 and then announced laptops that could convert 2D content into stereoscopic 3D in 2023. Those displays also relied on AI, as well as a specialized optical lens and a pair of eye-tracking cameras, to create the effect. But unlike Acer's portable monitors, Samsung claims that its monitor can make 2D content look like 3D even if that content doesn’t officially support 3D.

Meet Squid Game S3’s new killer doll

Squid Game's hotly anticipated second season debuted on Netflix the day after Christmas and racked up more than 68 million views in just three days. It had already been renewed for a third and final season—filmed back-to-back with S2—but Netflix ushered in the new year by gracing us with a 15-second teaser on X, introducing a brand new killer doll dubbed Chul-su—similar to the giant "Red Light, Green Light" doll Young-hee.

(Spoilers for S1 below; some spoilers for S2 but no major reveals.)

As previously reported, the first season followed Seong Gi-hun (Lee Jung-Jae, seen earlier this year in The Acolyte), a down-on-his-luck gambler who has little left to lose when he agrees to play children's playground games against 455 other players for money. The twist? If you lose a game, you die. If you cheat, you die. And if you win, you might also die.

How NASCAR and its teams are embracing 3D printing

Carbon fiber, aluminum, maybe the odd bit of titanium here or there: These are the materials we usually expect race cars to be made of. Now you can start adding thermoplastics like Ultem to the list. Additive manufacturing has become a real asset in the racer’s toolbox, although the technology has actually been used at the track longer than you might think.

"Some people think that 3D printing was invented last year," said Fadi Abro, senior global director of automotive and mobility at Stratasys. The company recently became NASCAR's official 3D printing partner, but it has a relationship with one of the teams—Joe Gibbs Racing—that stretches back two decades.

"Now the teams only have certain things that they can touch in the vehicle, but what that does is it makes it so that every microscopic advantage you can get out of that one tiny detail that you have control over is so meaningful to your team," Abro said.
