Think Pytest for LLMs. We spent the past year building DeepEval with the goal of providing the best LLM evaluation developer experience, growing it to run over 600K evaluations daily in CI/CD pipelines of enterprises like BCG, Astr

After 20 years, math couple solves major group theory problem

After the conjecture was posed in the 1970s, dozens of mathematicians tried their hand at proving it. They made partial progress — and in the process they learned a great deal about groups, which are abstract objects that describe the various symmetries of a mathematical system. But a full proof seemed out of reach. Then Späth came along. Now, 20 years after she first learned about the problem and more than a decade after she met Cabanes, the two mathematicians have finally completed the proof.

Jeff Bezos Is Already Soliciting Ideas for the Next James Bond

One of the world’s richest people is already playing with his latest toy. Thursday morning, news broke that the James Bond franchise, which was already owned by Amazon due to its 2022 purchase of MGM, was changing creative leadership. Michael G. Wilson and Barbara Broccoli, whose families had been controlling the franchise for 60 years, retained ownership but are passing creative control to Amazon. The move instantly sparked all sorts of speculation and debate about the massive corporation owni

Trump and Musk Double Down on Bogus ‘Stranded’ Starliner Astronauts Narrative

President Donald Trump and his bestest billionaire buddy Elon Musk continue to spread blatant lies about the situation surrounding the two Boeing Starliner astronauts currently aboard the ISS. In an interview with Fox News host Sean Hannity, the pair once again—falsely—said the two astronauts are stranded and in need of rescue, and baselessly pinned the blame on former president Joe Biden. In a transcript of the interview posted to the White House website, Trump made several false claims about

Star Trek: Voyager‘s First Brush With Getting Home Is One of Its Best

Star Trek: Voyager‘s premise was both its greatest boon and its biggest curse. Flinging the titular Starfleet vessel tens of thousands of lightyears away from Federation space into unchartered territory wasn’t just a fantastic evolution of the franchise’s original intent to boldly go where no man had gone before, but a vector for fascinating story ideas about resource management, ethics, first contact, and a million other Star Trek ideas that could be re-imagined in a context where the world est

OpenAI’s GPT-4.5 May Arrive Next Week, but GPT-5 Is Just Around the Corner

OpenAI may be preparing to slap a new coat of paint on ChatGPT with an updated AI model, GPT-4.5, as early as next week. If that’s not enough to get users excited, the Sam Altman-led company is on the path toward its ultimate model while trying to hint that this next step will finally achieve “AGI.” Spoiler alert: it won’t. Based on anonymous sources, the Verge’s Tom Warren first reported that OpenAI’s next model could hit the scene sometime this month. Microsoft reportedly plans to host the co

NASA Makes Big Update to Asteroid Potentially on Collision Course With Earth in 2032

The potentially hazardous asteroid 2024 YR4 caused consternation over the last few weeks as its odds of hitting Earth in 2032 dramatically rose. Now, those odds have plummeted to near-zero, as astronomers’ calculations of the asteroid’s path have been updated to indicate that Earth is almost certainly not in the space rock’s plans. Almost. According to NASA’s Center for Near-Earth Object Studies (CNEOS), the asteroid’s current chance of hitting the planet in 2032 is 0.28%, or a 1-in-360 shot. T

Apple Is Probably Planning to Make Its Own WiFi Chip For the iPhone 17

Apple rumors keep the world turning. Some people might say it’s gravity, but it’s Apple. Forget the Farmer’s Almanac; most farming relies on the iPhone release schedule. The iPhone 16e was revealed yesterday and brought a new future for Apple’s hardware, one where it makes all of its cellular chips. The iPhone 16e debuted the C1 modem, its first ever homemade, bespoke, perfectly spiced 5G chip. Reports today tell us that there are more chips on the way. The iPhone 17, expected much later this y

Microsoft’s Satya Nadella Pumps the Breaks on AI Hype

The world has yet to turn any of today’s AI hype and spending into a meaningful lift in the actual economy, says Microsoft CEO Satya Nadella. The comments were made during a podcast interview in which he put a measuring stick on AI’s true impact: Success will be measured through global economic growth rather than arbitrary benchmarks of how well AI programs can complete challenges like obscure math puzzles. Those are interesting in isolation but do not have practical utility. The comments seem

Twitch Announces New Storage Limits, Threatening Gamer Archives

The Internet is forever…until it isn’t. On Wednesday, Twitch announced that it will implement new limits on archived video Highlights and Uploads that users can store on their account. The new rules, set to take effect on April 19, 2025, will set a 100-hour storage limit on saved videos. Any account with more than 100 hours of content will need to manually remove highlights and uploads—including unpublished content that is saved to the channel but not publicly accessible—or be subject to an aut

Can Music Really Help You Sleep? Here's How to Build a Playlist for Deeper Slumber

Music fuels my life. Whether I'm writing, reading, working, running, driving or sitting around the house, music is usually flooding my ears or playing softly in the background. Choosing a song or playlist is the first thing I do in the morning, and if I have my AirPods in, you can count on Spotify playing my favorite podcasts. To me, music is a form of love. It boosts moods, soothes heartache and reaches audiences across language barriers. Music can also help you sleep at night, easing anxiety

Most People Still Aren't Happy With Their Internet, But It's Not All Bad

The American Customer Satisfaction Index released its annual survey, based on over 25,000 customer interviews, revealing how we really feel about our internet service providers. The good news for ISPs -- things are trending up. Overall, ISPs scored 71 on the ACSI's 100-point scale -- an increase of three points over 2023 and the highest score since the ACSI started measuring ISPs in 2013. The not-so-good news? Internet service providers still rank at the bottom of the index, just ahead of subscr

Canon's New Camera Is in a Category Once Thought Practically Dead

A new point-and-shoot camera? In 2025? That might seem surprising if you aren't up on the latest trends. The reality is the prices of used and older compact cameras have gone through the roof. There's a real interest, especially among younger people, for capable cameras separate from their phones. Canon follows recent announcements by Nikon, Panasonic and others with its new camera in a category once thought dead. The PowerShot V1 records 4K video at 60fps, takes 22.3-megapixel photos and has a

Best Headsets for Working From Home in 2025

A few years ago Shokz turned its OpenRun (formerly Aeropex) bone-conduction headphones into a more communications-friendly headset with an integrated boom microphone called the OpenComm ($140), which remains available. The second-generation OpenComm 2 UC costs more than the original, but it has an upgraded Bluetooth 5.1 chipset that improves performance a bit and now allows for the firmware upgrades that are required for Zoom certification. Additionally, the microphone has moved from the left ea

Mere weeks after Starship’s breakup, the vehicle may soon fly again

A little over a month after SpaceX's large Starship launch ended in an explosion over several Caribbean islands, the company is preparing its next rocket for a test flight. According to a notice posted by the Federal Aviation Administration, the eighth test flight of the Starship vehicle could take place as early as February 26 from the Starbase launch site in South Texas. The launch window extends from 5:30 pm local time (23:30 UTC) to 7:09 pm (01:09 UTC). Company sources confirmed that this

Amazon remembers it has an Android app store, kills it

After 14 years of trying and failing to gain a smartphone foothold, Amazon has announced it will discontinue its app store. Anyone who has content in Amazon's store will be able to access it for now, but all bets are off beginning on August 20, 2025. As part of the pull-back, the company is also discontinuing the Amazon Coins digital currency. The Amazon Appstore made waves when it launched in 2011, offering an alternative to what at the time was known as the Android Market. Amazon even scored

Twitch’s new storage limits will purge huge swaths of Internet gaming history

Popular Amazon-owned game streaming platform Twitch announced Wednesday that it will be imposing a 100-hour limit on the archived video highlights users can preserve permanently on the site. And while Twitch says that only 0.5 percent of users will be affected by these new limits, gamers are warning that the move threatens to eradicate large swaths of recent gaming history from the Internet. Highlights, in Twitch's own words, are a way for Twitch streamers to "show off your best moments to new

Elon Musk recommends that the International Space Station be deorbited ASAP

In a remarkable statement Thursday, SpaceX founder Elon Musk said the International Space Station should be deorbited "as soon as possible." This comment from Musk will surely set off a landmine in the global space community, with broad implications. And it appears to be no idle comment from Musk who, at times, indulges in deliberately provocative posts on the social media network X that he owns. However, that does not seem to be the case here. "It is time to begin preparations for deorbiting

Apple, Lenovo lead losers in laptop repairability analysis

Apple and Lenovo had the lowest laptop repairability scores in an analysis of recently released devices from consumer advocacy group US Public Interest Research Group (PIRG) Education Fund. While Apple's low marks are partially due the difficulty involved in disassembling MacBooks, Lenovo appears to be withholding information from shoppers deemed critical to right-to-repair legislation and accessibility. The report, US PIRG's fourth annual “Failing the Fix” [PDF], calculated repairability score

Small study suggests dark mode doesn’t save much power for very human reasons

If you know how OLED displays work, you know about one of their greatest strengths: Individual pixels can be shut off, offering deeper blacks and power savings. Dark modes, now available on most operating systems, aim to save power by making most backgrounds very dark or black, while also gratifying those who just prefer the look. But what about on the older but still dominant screen technology, LCDs? The BBC is out with a small, interesting study comparing the light and dark modes of one of it

SpaceX engineers brought on at FAA after probationary employees were fired

Engineers who work for Elon Musk’s SpaceX have been brought on as senior advisers to the acting administrator of the Federal Aviation Administration (FAA), sources tell WIRED. On Sunday, Sean Duffy, secretary of the Department of Transportation, which oversees the FAA, announced in a post on X that SpaceX engineers would be visiting the Air Traffic Control System Command Center in Virginia to take what he positioned as a tour. “The safety of air travel is a nonpartisan matter,” Musk replied. “S

ISP sued by record labels agrees to identify 100 users accused of piracy

Cable company Altice agreed to give Warner and other record labels the names and contact information of 100 broadband subscribers who were accused of pirating songs. The subscribers "were the subject of RIAA or third party copyright notices," said a court order that approved the agreement between Altice and the plaintiff record companies. Altice is notifying each subscriber "of Altice's intent to disclose their name and contact information to Plaintiffs pursuant to this Order," and telling the

Study: Cuttlefish adapt camouflage displays when hunting prey

Crafty cuttlefish employ several different camouflaging displays while hunting their prey, according to a new paper published in the journal Ecology, including mimicking benign ocean objects like a leaf or coral, or flashing dark stripes down their bodies. And individual cuttlefish seem to choose different preferred hunting displays for different environments. It's well-known that cuttlefish and several other cephalopods can rapidly shift the colors in their skin thanks to that skin's unique st

Nvidia GeForce RTX 5070 Ti review: An RTX 4080 for $749, at least in theory

Nvidia's RTX 50-series makes its first foray below the $1,000 mark starting this week, with the $749 RTX 5070 Ti—at least in theory. The third-fastest card in the Blackwell GPU lineup, the 5070 Ti is still far from "reasonably priced" by historical standards (the 3070 Ti was $599 at launch). But it's also $50 cheaper and a fair bit faster than the outgoing 4070 Ti Super and the older 4070 Ti. These are steps in the right direction, if small ones. We'll talk more about its performance shortly,

FTC investigates “tech censorship,” says it’s un-American and may be illegal

The Federal Trade Commission today announced a public inquiry into alleged censorship online, saying it wants "to better understand how technology platforms deny or degrade users' access to services based on the content of their speech or affiliations, and how this conduct may have violated the law." "Tech firms should not be bullying their users," said FTC Chairman Andrew Ferguson, who was chosen by President Trump to lead the commission. "This inquiry will help the FTC better understand how t
