Anthropic has released its Claude AI chatbot on the App Store, bringing the company's ChatGPT competitor to the masses. Compared to OpenAI's chatbot, Claude is built with a focus on reducing harmful outputs and promoting safety, with a goal of making interactions more reliable and ethically aware. You can give it a try here. 9to5Mac reports: Anthropic highlights three launch features for Claude on iPhone:

Seamless syncing with web chats: Pick up where you left off across devices.
Vision capabilities: Use photos from your library, take new photos, or upload files so you can have real-time image analysis, contextual understanding, and mobile-centric use cases on the go.
Open access: Users across all plans, including Pro and Team, can download the app free of charge.

The app is also capable of analyzing things that you show it like objects, images, and your environment.

Roblox announced it'll be rolling out virtual billboards with video advertisements that will be displayed in its virtual worlds. Reuters reports: Users will now see billboards featuring content from brands such as e.l.f beauty, Walmart and Warner Bros Discovery, just as they would in real life. That would give advertisers access to Roblox's nearly 72 million daily active users -- half of whom are Gen-Z customers, a population group prized by marketers and businesses.

The company in November began testing the video ads -- that will be served to users who are 13 years and older -- as part of its efforts to reduce reliance on revenue generated from its in-game currency "Robux", which players can use to buy outfits, vehicles and other features inside the company's digital worlds. It charges a fee on all purchases done on its platform, which hosts millions of videogames that are built by its users -- who get a share of any related revenue.

That practice will extend to the ads, with creators of the virtual worlds who opt to show the billboards getting a portion of the revenue Roblox makes from them. Roblox is hoping its large Gen-Z user base will give it an edge in the competitive ad market, where it would have to wrestle for marketing dollars with tech giants such as Google and Meta and smaller players such as Snap.

An anonymous reader quotes a report from Bloomberg: Dropbox said its digital-signature product, Dropbox Sign, was breached by hackers, who accessed user information including emails, user names and phone numbers. The software company said it became aware of the cyberattack on April 24, sought to limit the incident and reported it to law enforcement and regulatory authorities. "We discovered that the threat actor had accessed data related to all users of Dropbox Sign, such as emails and user names, in addition to general account settings," Dropbox said Wednesday in a regulatory filing. "For subsets of users, the threat actor also accessed phone numbers, hashed passwords, and certain authentication information such as API keys, OAuth tokens, and multi-factor authentication."

Dropbox said there is no evidence hackers obtained user accounts or payment information. The company said it appears the attack was limited to Dropbox Sign and no other products were breached. The company didn't disclose how many customers were affected by the hack. The hack is unlikely to have a material impact on the company's finances, Dropbox said in the filing. The shares declined about 2.5% in extended trading after the cyberattack was disclosed and have fallen 20% this year through the close.

The National Archives and Records Administration (NARA) told employees Wednesday that it is blocking access to ChatGPT on agency-issued laptops to "protect our data from security threats associated with use of ChatGPT," 404 Media reported Wednesday. From the report: "NARA will block access to commercial ChatGPT on NARANet [an internal network] and on NARA issued laptops, tablets, desktop computers, and mobile phones beginning May 6, 2024," an email sent to all employees, and seen by 404 Media, reads. "NARA is taking this action to protect our data from security threats associated with use of ChatGPT."

The move is particularly notable considering that this directive is coming from, well, the National Archives, whose job is to keep an accurate historical record. The email explaining the ban says the agency is particularly concerned with internal government data being incorporated into ChatGPT and leaking through its services. "ChatGPT, in particular, actively incorporates information that is input by its users in other responses, with no limitations. Like other federal agencies, NARA has determined that ChatGPT's unrestricted approach to reusing input data poses an unacceptable risk to NARA data security," the email reads. The email goes on to explain that "If sensitive, non-public NARA data is entered into ChatGPT, our data will become part of the living data set without the ability to have it removed or purged."

Microsoft has confirmed that the April 2024 Windows security updates break VPN connections across client and server platforms. From a report: The company explains on the Windows health dashboard that "Windows devices might face VPN connection failures after installing the April 2024 security update or the April 2024 non-security preview update."

"We are investigating user reports, and we will provide more information in the coming days," Redmond added. The list of affected Windows versions includes Windows 11, Windows 10, and Windows Server 2008 and later.

An anonymous reader shares a report: Two months after hackers broke into Change Healthcare systems stealing and then encrypting company data, it's still unclear how many Americans were impacted by the cyberattack. Last month, Andrew Witty, the CEO of Change Healthcare's parent company UnitedHealth Group, said that the stolen files include the personal health information of "a substantial proportion of people in America." On Wednesday, during a House hearing, when Witty was pushed to give a more definitive answer, testifying that the breach impacted "I think, maybe a third [of Americans] or somewhere of that level."

"Tens of millions" of people are using technical workarounds to secretly access WhatsApp in countries where it is banned, the messaging platform's boss has said. From a report: "You'd be surprised how many people have figured it out," Will Cathcart told BBC News. Like many Western apps, WhatsApp is banned in Iran and North Korea and, intermittently, in Syria. And last month, China joined the list of those banning users from accessing the secure platform. Other countries, including Qatar, Egypt, Jordan and the United Arab Emirates, restrict features such as voice calls.

But WhatsApp can see where its users truly are, thanks to their registered phone numbers. "We have a lot of anecdotal reports of people using WhatsApp and what we can do is look at some of the countries where we're seeing blocking and still see tens of millions of people connecting to WhatsApp," Mr Cathcart told BBC News. China ordered Apple to block Chinese iPhone users from downloading WhatsApp from the AppStore in April, a move Mr Cathcart calls "unfortunate" -- although the country was never a major market for the app. "That's a choice Apple has made," he said. "There aren't alternatives. I mean, that is really a situation where they've put themselves in the position to be able to truly stop something."

ArsTechnica: Sixty years ago, on May 1, 1964, at 4 am in the morning, a quiet revolution in computing began at Dartmouth College. That's when mathematicians John G. Kemeny and Thomas E. Kurtz successfully ran the first program written in their newly developed BASIC (Beginner's All-Purpose Symbolic Instruction Code) programming language on the college's General Electric GE-225 mainframe.

Little did they know that their creation would go on to democratize computing and inspire generations of programmers over the next six decades.

The US could lose out on valuable AI and tech talent if some of its immigration policies are not modernized, Google says in a letter sent to the Department of Labor. From a report: Google says policies like Schedule A, a list of occupations the government "pre-certified" as not having enough American workers, have to be more flexible and move faster to meet demand in technologies like AI and cybersecurity. The company says the government must update Schedule A to include AI and cybersecurity and do so more regularly.

"There's wide recognition that there is a global shortage of talent in AI, but the fact remains that the US is one of the harder places to bring talent from abroad, and we risk losing out on some of the most highly sought-after people in the world," Karan Bhatia, head of government affairs and public policy at Google, tells The Verge. He noted that the occupations in Schedule A have not been updated in 20 years.

Companies can apply for permanent residencies, colloquially known as green cards, for employees. The Department of Labor requires companies to get a permanent labor certification (PERM) proving there is a shortage of workers in that role. That process may take time, so the government "pre-certified" some jobs through Schedule A. The US Citizenship and Immigration Services lists Schedule A occupations as physical therapists, professional nurses, or "immigrants of exceptional ability in the sciences or arts." While the wait time for a green card isn't reduced, Google says Schedule A cuts down the processing time by about a year.

Windows 11's market share dropped in April 2024, falling below 26% after reaching an all-time high of 28.16% in February. According to Statcounter, Windows 11 lost 0.97 points, while Windows 10 gained 0.96 points, crossing the 70% mark for the first time since September 2023. Neowin adds: Some argue that Windows 11 still offers little to no benefits for upgrading, especially in light of Microsoft killing some of the system's unique features, such as Windows Subsystem for Android. Add to that the ever-increasing number of ads, some of which are quite shameless, and you get an operating system that has a hard time winning hearts and minds, and retaining its customers.

LastPass, the password manager company, has officially separated from its parent company, GoTo, following a series of high-profile hacks in recent years. The company will now operate under a shareholder holding company called LMI Parent.

LastPass -- owned by private equity firms Francisco Partners and Elliott Management -- has faced criticism for its handling of the breaches, which resulted in the theft of customer data and encryption keys. The company has since enforced a 12-character minimum for master passwords to improve security.

Microsoft's motivation for investing heavily and partnering with OpenAI came from a sense of falling badly behind Google, according to an internal email released Tuesday as part of the Justice Department's antitrust case against the search giant. Bloomberg: The Windows software maker's chief technology officer, Kevin Scott, was "very, very worried" when he looked at the AI model-training capability gap between Alphabet's efforts and Microsoft's, he wrote in a 2019 message to Chief Executive Officer Satya Nadella and co-founder Bill Gates. The exchange shows how the company's top executives privately acknowledged they lacked the infrastructure and development speed to catch up to the likes of OpenAI and Google's DeepMind.

[...] Scott, who also serves as executive vice president of artificial intelligence at Microsoft, observed that Google's search product had improved on competitive metrics because of the Alphabet company's advancements in AI. The Microsoft executive wrote that he made a mistake by dismissing some of the earlier AI efforts of its competitors. "We are multiple years behind the competition in terms of machine learning scale," Scott said in the email. Significant portions of the message, titled 'Thoughts on OpenAI,' remain redacted. Nadella endorsed Scott's email, forwarding it to Chief Financial Officer Amy Hood and saying it explains "why I want us to do this."

The massive volumes of debt piling up around the globe forced the president of the World Economic Forum to reach back more than 200 years for a comparable period. Fortune: In an interview Sunday with CNBC at a WEF conference in Saudi Arabia, Borge Brende warned overall debt is approaching the world's total economic output. "We haven't seen this kind of debt since the Napoleonic Wars," he said. "We're getting close to 100% of global GDP in debt."

According to the International Monetary Fund last year, global public debt hit $91 trillion, or 92% of GDP, by the end of 2022. That was actually a dip from pandemic-era debt levels but remained in line with a decades-long trend higher. Data on global debt during the Napoleonic Wars, which took place in the early 1800s, is harder to come by. But for comparison, some estimates put British government debt at more than 200% of GDP by 1815.

Brende also told CNBC that governments need to take fiscal measures to reduce their debts without triggering a recession. For now, global growth is about 3.2% annually, which isn't bad, but it's also below the 4% trend growth the world had seen for decades, he said earlier in the interview. That risks a repeat of the 1970s, when growth was low for a decade, Brende added. But the world can avoid such an outcome if it continues to trade and doesn't engage in more trade wars. "Trade was the engine of growth for decades," he said.

LinkedIn, the professional network known for job listings and unsolicited career advice, is jumping into gaming. From a report: The platform is officially introducing a set of Wordle-style puzzle games, weeks after they were first spotted in the app. The company is starting with three games: Pinpoint, a word game where players must guess the theme that ties a series of words together; Queens, a puzzle game that's a bit like a cross between Sudoku and Minesweeper; and Crossclimb, a trivia game that involves guessing a series of four-letter words and placing them in the correct order.

LinkedIn describes them as "thinking-oriented games," though the format will likely look familiar to fans of The New York Times Games app. Each game can only be played once a day, and players can share their score with friends in cute emoji-filled messages reminiscent of the "Wordle grid." The service will also keep track of "streaks," to encourage players to come back every day. Given the similarities, it shouldn't be surprising that games were developed by LinkedIn's news team, which recently hired a dedicated games editor.

An anonymous reader shares a report: Harvard geneticist David Sinclair, who has said his "biological age" is roughly a decade younger than his actual one, has put forward his largely unlined face as a spokesman for the longevity movement. The 54-year-old has built his brand on the idea that aging is a treatable disease. The notion has proven so seductive that legions of acolytes follow his online postings about his research and the cocktails of supplements he consumes to stave off the inevitable. His social-media accounts are a platform for assertions that his work is pushing nearer to a fountain of youth. He claimed last year that a gene therapy invented in his Harvard lab and being developed by a company he co-founded, Life Biosciences, had reversed aging and restored vision in monkeys. "Next up: age reversal in humans," he wrote on X and Instagram.

On Feb. 29, in the eyes of many other scientists working to unlock the mysteries of aging, he went too far. Another company he co-founded, Animal Biosciences, quoted him in a press release saying that a supplement it had developed had reversed aging in dogs. Scientists who study aging can't even agree on what it means to "reverse" aging, much less how to measure it. The response was swift and harsh. The Academy for Health and Lifespan Research, a group of about 60 scientists that Sinclair co-founded and led, was hit with a cascade of resignations by members outraged by his claims. One scientist who quit referred to Sinclair on X as a "snake oil salesman." Days later, in a tense video meeting, the academy's five other board members pressed Sinclair to resign as president. He contended that the press release contained an inaccurate quote, according to people who were in the meeting, but he later stepped down.

Sinclair's work is published regularly in top-tier scientific journals and has brought attention to an emerging field vying for credibility and funding. He has parlayed his research into hundreds of millions of dollars of investment in various companies, more than 50 patents and prominence as a longevity influencer. Along the way, his claims -- especially in his social-media posts, interviews and his book -- have drawn criticism from scientists who have accused him of hyping his research and extolling unproven products, including some from companies in which he had a financial interest. "My lab's ideas and findings are typically ahead of the curve, which is why some peers might feel the research is overstated at the time," Sinclair said to The Wall Street Journal in an email. "I stand behind my track record as a trusted scientist in one of the most competitive professions of all." He said he doesn't engage with social-media critics, including those calling him a snake oil salesman, and that many such comments are "nothing more than mischaracterizations."
