Last May Duolingo's stock peaked at $529.05. But while the learning app passed $1 billion in revenue in 2025 and 50 million daily active users, today its stock price has dropped more than 81%, to $100.51. And there's been other changes, reports Entrepreneur: In April 2025, Duolingo CEO Luis von Ahn made headlines after writing a memo calling the company "AI-first." In the memo, von Ahn announced that the language-learning platform would track employees' AI use in performance reviews. Now, a year later, von Ahn is backtracking and rethinking how he measures employee performance. He told the Silicon Valley Girl podcast earlier this month that Duolingo no longer considers AI use in performance reviews. The change arose after employees started to ask, "Do you just want us to use AI for AI's sake?" von Ahn explained. "We said no, look — the most important thing in your performance is that you are doing whatever your job is as well as possible. A lot of times, AI can help you with that, but if it can't, I'm not going to force you to do that," von Ahn said on the podcast. He felt as though the company was "trying to push something that in some cases did not fit" instead of "being held accountable for the actual outcome." The CEO is, however, still sticking to other "constructive constraints" he introduced in the April 2025 memo, including stopping contractor hiring in cases where AI can assume their workload... Von Ahn also mentioned that a few months ago, Duolingo had a day dedicated to vibe coding, or prompting AI to create an app without manually writing a single line of code. Every single person at the company, from engineers to human resources professionals, had to vibe code an app. Vibe coding has made an impact at the company. One of Duolingo's latest offerings, a course teaching users how to play chess, arose when two people vibe-coded the first prototype of it, the CEO said. Neither of them knew how to play chess or program, but they managed to use AI to create the whole chess curriculum and a prototype of the app in about six months last year. Now chess is Duolingo's fastest-growing course, according to von Ahn. "At this point, we have seven million daily active users that are learning chess," the CEO said on the podcast.

After Artemis II's astronauts returned to earth, "NASA has Artemis III in its sights," reports the Associated Press: In a mission recently added to the docket for next year, Artemis III's yet-to-be -named astronauts will practice docking their Orion capsule with a lunar lander or two in orbit around Earth. Elon Musk's SpaceX and Jeff Bezos' Blue Origin are racing to have their company's lander ready first. Musk's Starship and Bezos' Blue Moon are vying for the all-important Artemis IV moon landing in 2028. Two astronauts will aim for the south polar region, the preferred location for [NASA Administrator Jared] Isaacman's envisioned $20 billion to $30 billion moon base. Vast amounts of ice are almost certainly hidden in permanently shadowed craters there — ice that could provide water and rocket fuel. The docking mechanism for Artemis III's close-to-home trial run is already at Florida's Kennedy Space Center. The latest model Starship is close to launching on a test flight from South Texas, and a scaled-down version of Blue Moon will attempt a lunar landing later this year.

"A trailer has been released for the first film to star an authorised generative AI version of a major Hollywood actor," writes The Guardian: Val Kilmer was cast in western As Deep As the Grave before his death in April 2025. Production delays meant he never shot any scenes, but the creative team worked with UK-based company Sonantic to create an AI speaking voice based on his old recordings. His estate and daughter Mercedes collaborated with the film-makers on the visual deepfake of the actor. Kilmer, who was diagnosed with throat cancer, was also assisted by technology for his cameo in 2022's Top Gun: Maverick... Writer-director Coerte Voorhees confirmed that Kilmer is seen for around an hour of the film's running time... Voorhees has said that the production followed Sag-Aftra [union] guidelines, and that Kilmer's estate — which provided archival material for them to use — was compensated financially. "Kilmer's likeness can be seen portraying Father Fintan, a Catholic priest and Native American spiritualist," adds The Hollywood Reporter. But the AV Club calls it "ghoulish puppet show time." "Having your AI Val Kilmer puppet whisper 'Don't fear the dead, and don't fear me' in a movie trailer is a bold choice..." He is accompanied (per Variety) by a whole host of disclaimers, caveats, and explanations offered by writer-director Coerte Voorhees and his associates: Kilmer deeply wanted to be in the movie, but was too sick to do so. His family endorses and supports his inclusion. He was a big fan of technology, including, presumably, its use in turning his own image into a digital avatar to then shove into movies... The fact is, of course, that nobody would be paying a fraction of this attention to As Deep As The Grave — about early female archeologist Ann Axtell Morris — if it weren't now being used as the stage on which Voorhees was very publicly accepting the dare to go full-on ghoulish with AI tech. "The filmmakers said they hoped they were showing Hollywood how to use the technology in a positive way..." notes Australia's ABC News. But their articles add that "Some have called the trailer 'terrifying' and 'disgusting' on social media." Mashable writes: "Very fitting that this trailer includes a scene where a corpse is unceremoniously yanked out of the ground," read one of the top comments on As Deep as the Grave's trailer at time of writing... [O]nline commenters have labelled it disgusting and disrespectful, not only for digitally reanimating Kilmer but also for the damaging precedent As Deep as the Grave's use of AI could set for the film industry as a whole.

Slashdot reader Bismillah shared this report from ITNews: Research and development engineer Romain Marchand of Paris headquartered Quarkslab obtained a telematic control unit (TCU) from a salvage yard in Poland... Marchand tore down the TCU, which is based on a Qualcomm system on a chip, and extracted the Linux-based file system from the Micron multi-chip package (MCP) which contained NAND-based non-volatile storage memory. The non-volatile storage contained sensitive information, including system configuration data and more importantly, logs that revealed the vehicle's GPS positions over time. None of that information was encrypted, Marchand told iTnews, which made it possible to collect and retrieve sensitive data of interest. What's more, the global navigation satellite system (GNSS) logs with GPS positions covered the BYD's full journey from the factory in China to its operational life in the United Kingdom, and to its final wrecking in Poland, Marchand explained in an analysis... The issue is not restricted to BYD, and Marchand added that the hardware architecture of the Chinese car maker's TCU is broadly similar to what can be found in other brands.

"From 2008 to 2024, the number of four-year computer science degrees granted rose about fivefold..." reports the Washington Post. Then in 2025 CS suddenly dropped from the fourth-largest undergraduate major to sixth, they report (citing data from the nonprofit National Student Clearinghouse, which compiles numbers from 97% of U.S. universities. The 54,000-student drop was "the biggest one-year drop of any major discipline going back to at least 2020." But what major are they choosing instead? Sarah Karamarkovich, a research associate with the National Student Clearinghouse, pointed to an explanation from the data that we had overlooked. Enrollments in two interdisciplinary majors, data analytics and data science, topped a combined 35,000 in the fall of 2025. That was up from a few hundred when those disciplines were broken out into their own majors in 2020. Those relatively new categories reflect colleges' zeal to create specialized majors, including in AI, data science, robotics and cybersecurity. Some of those disciplines may be counted in the national enrollment data as computer science. Others are not. The numbers suggest that some of the disappearing computer science majors didn't flee so much as they splintered into related disciplines.... The 8 percent decline in computer science majors last fall was nearly mirrored by a 7.3 percent increase in engineering majors, according to the National Student Clearinghouse data. Within engineering, mechanical and electrical engineering major enrollments increased by the largest absolute amounts — a jump of 11 percent and 14 percent, respectively.

Yesterday the U.S. Congress approved "a short-term extension" of a FISA law that allows wiretaps without a warrant for surveilling foreign targets, reports CNN — but only until April 30. Republican congressional leaders had sought an 18-month extension, but "failed to secure" the votes after "clamoring from some of their members for reforms to protect Americans' privacy." The warrantless surveillance law, known as Section 702 of the Foreign Intelligence Surveillance Act, was set to expire on Monday night. Members are hoping the additional time will allow them to come to agreement without ending authorization for the intelligence gathering program, which permits US officials to monitor phone calls and text messages from foreign targets... There was an hour of suspense in the Senate Friday morning when it appeared possible that Democratic Sen. Ron Wyden, a longtime critic of FISA 702, might block the House-passed extension. But ultimately, he said his House colleagues had assured him "this short-term extension makes reform more likely, and expiration makes reform less likely," and so he chose not to object.... House Republican leaders believed Thursday night they had struck a deal with conservative holdouts who harbor deep and longstanding concerns that a key piece of the law infringes on Americans' privacy rights. But in a pair of after-midnight votes, more than a dozen rank-and-file Republicans rejected the long-term reauthorization plan on the floor, which was the result of days of tense negotiations among leadership, lawmakers and the White House. The law allows authorized US officials to gather phone calls and text messages of foreign targets, but they can also incidentally collect the data of Americans in the process. Senior national security officials have for years said the law is critical for thwarting terror attacks, stemming the flow of fentanyl into the US and stopping ransomware attacks on critical infrastructure. Civil liberties groups on the left and the right, meanwhile, argue the surveillance authority risks infringing on Americans' privacy.

Wednesday BleepingComputer reported that more than 30 WordPress plugins "have been compromised with malicious code that allows unauthorized access to websites running them." A malicious actor planted the backdoor code last year but only recently started pushing it to users via updates, generating spam pages and causing redirects, as per the instructions received from the command-and-control (C2) server. The compromise affects plugins with hundreds of thousands of active installations and was spotted by Austin Ginder, the founder of managed WordPress hosting provider Anchor Hosting, after receiving a tip about one add-on containing code that allowed third-party access. Further investigation by Ginder revealed that a backdoor had been present in all plugins within the EssentialPlugin package since August 2025, after the project was acquired in a six-figure deal by a new owner.... "The injected code was sophisticated. It fetched spam links, redirects, and fake pages from a command-and-control server. It only showed the spam to Googlebot, making it invisible to site owners," explained Ginder. "WordPress.org's v2.6.9.1 update neutralized the phone-home mechanism in the plugin," Ginder writes in a blog post. "But it did not touch wp-config.php. The SEO spam injection was still actively serving hidden content to Googlebot. "And here is the wildest part. It resolved its C2 domain through an Ethereum smart contract, querying public blockchain RPC endpoints. Traditional domain takedowns would not work because the attacker could update the smart contract to point to a new domain at any time." This has happened before. In 2017, a buyer using the alias "Daley Tias" purchased the Display Widgets plugin (200,000 installs) for $15,000 and injected payday loan spam. That buyer went on to compromise at least 9 plugins the same way.... The WordPress plugin marketplace has a trust problem... The Flippa listing for Essential Plugin was public. The buyer's background in SEO and gambling marketing was public. And yet the acquisition sailed through without any review from WordPress.org. WordPress.org has no mechanism to flag or review plugin ownership transfers. There is no "change of control" notification to users. No additional code review triggered by a new committer. The Plugins Team responded quickly once the attack was discovered. But 8 months passed between the backdoor being planted and being caught. Thanks to Slashdot reader axettone for sharing the news.

Slashdot reader smazsyr writes: A new review says we've had fructose wrong for decades. The nine authors, led by Richard Johnson at the University of Colorado Anschutz, argue that fructose "is not just another calorie." It is a signal. It tells the liver to make fat and brace for a famine that never comes. That made sense for a bear fattening up on autumn berries. It makes less sense for a person drinking soda in March. The review reframes the WHO's sugar guideline, argues ScienceBlog.com, as "less a recommendation about calories and more a warning about a signalling molecule we have been dosing ourselves with, several times a day, for most of a century."

20-year-old Matthew Lane sent a text message to ABC News as his parents drove him to federal prison in Connecticut. "I'm just scared," he said, calling the whole situation "extremely sad." Barely a year earlier, while still a teenager, he helped launch what's been described as the biggest cyberattack in U.S. education history — a data breach that concerned authorities so much, it prompted briefings with senior government officials inside the White House Situation Room. The breach pierced the education technology company PowerSchool — used by 80% of school districts in North America... [and operating in about 90 countries around the world]. With threats to expose social security numbers, dates of birth, family information, grades, and even confidential medical information, the breach cornered PowerSchool into paying millions of dollars in ransom. "I think I need to go to prison for what I did," Lane told ABC News in an exclusive interview, speaking publicly for the first time about the headline-grabbing heist and his life as a cybercriminal. "It was disgusting, it was greedy, it was rooted in my own insecurities, it was wrong in every aspect," he said in the interview, two days before reporting to prison... At about 6:30 on a Tuesday morning last April, FBI agents started banging on the door of Lane's second-floor dorm room. "FBI! We have a search warrant," Lane recalled them shouting. They seized his devices and many of the luxury items he bought with "dirty" money, as he put it. He said he felt a "wave of relief.... I'm honestly thankful for the FBI," he said. "After they left, I was like, 'It's over ... I'm done with this'..." A federal judge in Massachusetts sentenced him to four years in federal prison and ordered him to pay more than $14 million in restitution. "In the wake of the breach, PowerSchool offered two years' worth of credit-monitoring and identity protection services to concerned customer," the article points out. But it also notes two other arrests in September of teenaged cybercriminals: - A 15-year-old boy in Illinois who allegedly attacked Las Vegas casinos, reportedly costing MGM Resorts alone more than $100 million - A British national who when he was 16 helped breach over 110 companies around the world and extort $115 million. But ironically, Lane tells ABC News it all started on Roblox, where he'd met cheaters, password-stealers, and cybercriminals sharing photos of their stacks of money, creating a "sense of camaraderie" Lane and others warn that online forums also attract criminal groups seeking to recruit potential hackers. "The bad guys are on all the platforms watching the kids playing," Hay said. "And when they see an elite-level performer, they go approach that kid, masquerading as another kid, and they go, 'Hey, you want to earn some [money]? ... Here are the tools, here are the techniques'...." According to Lane, he spent his "ill-gotten gains" on designer clothes, diamond jewelry, DoorDash deliveries, Airbnb rentals for him and his friends, and drugs — "lots of drugs." He said he would numb ever-present feelings of guilt with drugs — from high-potency marijuana to acid. But it was hacking that gave him the strongest high. "It's indescribable the adrenaline you get when you do something like that," he said. "It's way more than driving 120 miles per hour. ... Incomparable to any drug at all, as well." "On Monday, Roblox announced that, starting in June, it will offer age-checked accounts for younger users that limit what games they can play, and add 'more closely align content access, communication settings, and parental controls with a user's age.'"
