On a sweltering July evening, the din from thousands of computers mining for Bitcoins pierced the night. Nearby, Matt Brown, a member of the Arkansas legislature, monitored the noise alongside a local magistrate.As the two men investigated complaints about the operation, Mr. Brown said, a security guard for the mine loaded rounds into an AR-15-style assault rifle that had been stored in a car.“He wanted to make sure that we knew he had his gun — that we knew it was loaded,” Mr. Brown, a Republican, said in an interview.The Bitcoin outfit here, 45 minutes north of Little Rock, is one of three sites in Arkansas owned by a network of companies embroiled in tense disputes with residents, who say the noise generated by computers performing trillions of calculations per second ruins lives, lower...

With its streamlined curves and glow-in-the-dark sound system, the silver Lamborghini Huracán Performante was the stuff of teenage fantasy: $350,000 of aerodynamic metals and lightweight upholstery, packed into a taut and powerful body. Ben Armstrong loved it dearly.When he started shopping for a Lamborghini, Mr. Armstrong, a cryptocurrency evangelist with more than one million YouTube subscribers, worried that he’d have to spend months searching. “I think I have to go to Italy to get the Lambo I want,” he texted a business partner. “I don’t want to compromise.” But fate smiled on him. In the fall of 2021, a car dealership in Charlotte, N.C., shipped the Huracán to Mr. Armstrong’s production studio in an Atlanta suburb.As the Lamborghini was lowered from a delivery truck, Mr. Armstrong, be...

Next week, Satya Nadella will hit his 10th anniversary as the company’s chief executive.For Microsoft, the pressure to keep delivering is on.In particular, investors are looking for the company to cash in on what they see as its lead in artificial intelligence.

The genetic testing company 23andMe is being accused in a class-action lawsuit of failing to protect the privacy of customers whose personal information was exposed last year in a data breach that affected nearly seven million profiles.The lawsuit, which was filed on Friday in federal court in San Francisco, also accused the company of failing to notify customers with Chinese and Ashkenazi Jewish heritage that they appeared to have been specifically targeted, or that their personal genetic information had been compiled into “specially curated lists” that were shared and sold on the dark web.The suit was filed after 23andMe submitted a notification to the California Attorney General’s Office that showed the company was hacked over the course of five months, from late April 2023 through Sept...

In the spring of 2020, when President Donald J. Trump wrote messages on Twitter warning that increased reliance on mail-in ballots would lead to a “rigged election,” the platform ran a corrective, debunking his claims.“Get the facts about mail-in voting,” a content label read. “Experts say mail-in ballots are very rarely linked to voter fraud,” the hyperlinked article declared.This month, Elon Musk, who has since bought Twitter and rebranded it X, echoed several of Mr. Trump’s claims about the American voting system, putting forth distorted and false notions that American elections were wide open for fraud and illegal voting by noncitizens.This time, there were no fact checks. And the X algorithm — under Mr. Musk’s direct control — helped the posts reach large audiences, in some cases draw...

Voters in New Hampshire received robocall messages over the weekend in a voice that was most likely artificially generated to impersonate President Biden’s, urging them not to vote in Tuesday’s primary election, according to the state attorney general’s office.The fake recordings, which told listeners that “your vote makes a difference in November, not this Tuesday,” were manipulated to seem as if they had been sent by an officer of a Democratic committee, the office said.The attorney general’s office stressed that voting in the primary would not rule out voters from also casting ballots in the general election in November.“These messages appear to be an unlawful attempt to disrupt the New Hampshire presidential primary election and to suppress New Hampshire voters,” the office said in a s...

When Apple released the Apple Watch in 2015, it was business as usual for a company whose iPhone updates had become cultural touchstones. Before the watch went on sale, Apple gave early versions of it to celebrities like Beyoncé, featured it in fashion publications like Vogue and streamed a splashy event on the internet trumpeting its features.But as Apple prepared to sell its next generation of wearable computing, the Vision Pro augmented reality device, it marched far more quietly into the consumer marketplace.The company said in a news release this month that sales of the device would begin Friday. No big product event was scheduled, though Apple has created a catchy commercial about the device and offered individual demonstrations of it to tech reviewers. And in a departure for the sec...
