Didi Global tumbled Friday after China said it's starting a cybersecurity review of the ride-hailing company just two days after it pulled off one of the biggest U.S. stock market debuts of the past decade. From a report: The move is to prevent data security risks, safeguard national security and protect public interest, according to a statement from the Cyberspace Administration of China. Didi has halted new user registrations during the probe. The company, which only started trading on Wednesday in New York after an initial public offering, fell 7% to $15.26.

The surprise probe by China's internet regulator piles on the scrutiny of Didi over issues ranging from antitrust to data security. The company has been grappling with a broad antitrust probe into China's internet firms with uncertain outcomes for Didi and peers like major backer Tencent. More broadly, Beijing has been curbing the growing influence of China's largest internet corporations, widening an effort to tighten the ownership and handling of troves of information that internet giants from Alibaba Group to Tencent and Didi scoop up daily from hundreds of millions of users. Didi lost as much as 11% of its market value at one point on Friday, a rapid turnaround that underscores the uncertainty surrounding the Chinese government's crackdown on the internet sector.

Europe's tech chief Margrethe Vestager on Friday warned iPhone maker Apple against using privacy and security concerns to fend off competition on its App Store, reasons CEO Tim Cook gave for not allowing users to install software from outside the Store. From a report: Vestager, who is also the European Commission's executive vice president, last year proposed rules called the Digital Markets Act (DMA) that would force Apple to open up its lucrative App Store so that users can download apps from the internet or third-party app stores in a practice known as side-loading. Cook, speaking at an event last month, said the proposal would destroy the security and privacy of iPhones. read more Vestager said she shares Cook's security concerns. "I think privacy and security is of paramount importance to everyone," Vestager told Reuters in an interview.

"The important thing here is, of course, that it's not a shield against competition, because I think customers will not give up neither security nor privacy if they use another app store or if they sideload," she said. Vestager indicated that she was open to changes in her proposal, which needs input from EU countries and EU lawmakers before it can become law. "I think that it is possible to find solutions to this," she said.

Instagram doesn't see itself as a platform where people go to share photos anymore. From a report: That's the main takeaway from a series of recent comments made by the head of the company, Adam Mosseri. "We're no longer a photo-sharing app or a square photo-sharing app," Mosseri said in a video he posted to his social media accounts this week. According to Mosseri, the main reason for that is that people come to Instagram "to be entertained," and it's not the only app that offers that in what is a crowded marketplace. "Let's be honest, there's some really serious competition right now," Mosseri said. "TikTok is huge, YouTube is even bigger and there are a lot of other upstarts as well." To stay competitive, Mosseri said Instagram has to embrace that aspect of itself, "and that means change." One way the app will change is with Instagram handing out more recommendations

Qualcomm's new chief thinks that by next year his company will have just the chip for laptop makers wondering how they can compete with Apple, which last year introduced laptops using a custom-designed central processor chip that boasts longer battery life. From a report: Longtime processor suppliers Intel and Advanced Micro Devices have no chips as energy efficient as Apple's. Qualcomm Chief Executive Cristiano Amon told Reuters on Thursday he believes his company can have the best chip on the market, with help from a team of chip architects who formerly worked on the Apple chip but now work at Qualcomm. In his first interview since taking the top job at San Diego, California-based Qualcomm, Amon also said the company is also counting on revenue growth from China to power its core smartphone chip business despite political tensions. "We will go big in China," he said, noting that U.S. sanctions on Huawei give Qualcomm an opportunity to generate a lot more revenue.

OpenStreetMap, the Wikipedia-for-maps organisation that seeks to create a free and open-source map of the globe, is considering relocating to the EU, almost 20 years after it was founded in the UK by the British entrepreneur Steve Coast. From a report: OpenStreetMap Foundation, which was formally registered in 2006, two years after the project began, is a limited company registered in England and Wales. Following Brexit, the organisation says the lack of agreement between the UK and EU could render its continued operation in Britain untenable. "There is not one reason for moving, but a multitude of paper cuts, most of which have been triggered or amplified by Brexit," Guillaume Rischard, the organisation's treasurer, told members of the foundation in an email sent earlier this month.

One "important reason," Rischard said, was the failure of the UK and EU to agree on mutual recognition of database rights. While both have an agreement to recognise copyright protections, that only covers work which is creative in nature. Maps, as a simple factual representation of the world, are not covered by copyright in the same way, but until Brexit were covered by an EU-wide agreement that protected databases where there had been "a substantial investment in obtaining, verifying or presenting the data." But since Brexit, any database made on or after 1 January 2021 in the UK will not be protected in the EU, and vice versa.

In a surprise announcement today, IBM announced that Jim Whitehurst, who came over in the Red deal, would be stepping down as company president just 14 months after taking over in that role. From a report: IBM didn't give a lot of details as to why he was stepping away, but acknowledged his key role in helping bring the 2018 $34 billion Red Hat deal to fruition and helping bring the two companies together after the deal closed. "Jim has been instrumental in articulating IBM's strategy, but also, in ensuring that IBM and Red Hat work well together and that our technology platforms and innovations provide more value to our clients," the company stated.

He will stay on as a senior advisor to Krishna, but it begs the question why he is leaving after such a short time in the role, and what he plans to do next. Oftentimes after a deal of this magnitude closes, there is an agreement as to how long key executives will stay. It could be simply that the period has expired and Whitehurst wants to move on, but some saw him as the heir apparent to Krishna and the move comes as a surprise when looked at in that context.

An anonymous reader shares a report: As early as 1958, the oil industry was hiring scientists and engineers to research the role that burning fossil fuels plays in global warming. The goal at the time was to help the major oil conglomerates understand how changes in the earth's atmosphere may affect the industry -- and their bottom line. But what top executives gained was an early preview of the climate crisis, decades before the issue reached public consciousness. What those scientists discovered -- and what the oil companies did with that information -- is at the heart of two dozen lawsuits attempting to hold the fossil fuel industry responsible for their role in climate change.

Many of those cases hinge on the industry's own internal documents that show how, 40 years ago, researchers predicted the rising global temperatures with stunning accuracy. But looking back, many of those same scientists say they were hardly whistleblowers out to take down big oil. Some researchers later testified before Congress, using their insider knowledge to highlight the ways in which the oil industry misled the public. Others say they have few qualms with how the petroleum giants handled their research. Few, however, could have predicted the imprint their work would have on history in efforts to hold the fossil fuel industry accountable for our climate emergency. The Guardian tracked down three of those scientists to see how they view their role today.

Too much has been lost already. The glue that holds humanity's knowledge together is coming undone. From a report: It turns out that link rot and content drift are endemic to the web, which is both unsurprising and shockingly risky for a library that has "billions of books and no central filing system." Imagine if libraries didn't exist and there was only a "sharing economy" for physical books: People could register what books they happened to have at home, and then others who wanted them could visit and peruse them. It's no surprise that such a system could fall out of date, with books no longer where they were advertised to be -- especially if someone reported a book being in someone else's home in 2015, and then an interested reader saw that 2015 report in 2021 and tried to visit the original home mentioned as holding it. That's what we have right now on the web.

[...] People tend to overlook the decay of the modern web, when in fact these numbers are extraordinary -- they represent a comprehensive breakdown in the chain of custody for facts. Libraries exist, and they still have books in them, but they aren't stewarding a huge percentage of the information that people are linking to, including within formal, legal documents. No one is. The flexibility of the web -- the very feature that makes it work, that had it eclipse CompuServe and other centrally organized networks -- diffuses responsibility for this core societal function.

Some Facebook users in the United States are being served a prompt that asks if they are worried that someone they know might be becoming an extremist. Others are being notified that they may have been exposed to extremist content. From a report: It is all part of a test the social media company is running that stems from its Redirect Initiative, which aims to combat violent extremism, Andy Stone, a Facebook spokesperson, told CNN. Screen shots of the alerts surfaced on social media Thursday. "This test is part of our larger work to assess ways to provide resources and support to people on Facebook who may have engaged with or were exposed to extremist content, or may know someone who is at risk," Stone said. "We are partnering with NGOs and academic experts in this space and hope to have more to share in the future," Stone added. One of the alerts, a screen grab of which made the rounds on social media Thursday, asks users, "Are you concerned that someone you know is becoming an extremist?" "We care about preventing extremism on Facebook," explained that alert, according to a screen grab posted on social media. "Others in your situation have received confidential support."

An anonymous reader quotes a report from Scientific American: The United Kingdom will end its use of coal-fired power by October 2024, a year earlier than scheduled, as it pushes other countries toward greater climate ambition ahead of a global warming summit it's hosting in November. "Coal powered the industrial revolution 200 years ago, but now is the time for radical action to completely eliminate this dirty fuel from our energy system," Energy and Climate Change Minister Anne-Marie Trevelyan said in a statement yesterday. It won't have far to go. Coal accounted for just 1.8% of the U.K.'s electricity mix last year, with roughly 43% coming from renewable sources such as wind and solar, according to the U.K. Department for Business, Energy and Industrial Strategy. The government plans to introduce legislation on the coal phaseout "at the earliest opportunity," it said. It will only apply to coal used in electricity generation, not other sectors such as the steel industry.

According to Axios, Jason Miller, an aide and close advisor to Donald Trump, is launching a new social app called "Gettr" in the coming days. From the report: The app, which is in beta testing, appears in the Apple App Store and is described as "a non-bias social network for people all over the world." Gettr, which is still in its infancy, appears to have a few thousand users, according to follower counts of some of the more prominent, suggested accounts. Many users, however, appear anonymous, lacking much profile information. The app looks like Twitter, with a scrolling news feed with a small pencil at the bottom for users to compose a message. It has a search function and like Twitter, a trending topics function. While a quick scroll through the accounts suggests patterns pro-conservatism, there's no obvious suggestion that the app is built by Trump allies. Many of the more prominent suggested accounts, including a general news account called "Daily News" appear to have been created in May of this year. [...] It's unclear how Miller plans to debut the app, but sources tell Axios that other former Trump aides will help aide the rollout. "Data shows that almost every major conservative social network has seen a dramatic decrease in downloads since the Capitol insurrection," notes Axios.

One of the most recent conservative social media sites to be launched was FRANK, a social media site envisioned by Mike Lindell of MyPillow. It's off to a rough start though, as it not only resulted in a legal threat before being launched, but it suffered from many "amateur-hour mistakes" during its rollout. A Drupal expert described the code as "not even student work," adding that "they basically launched the site while it was still in development mode."

As Axios reports, a company called playerWON (kill me), described as "a first-of-its-kind in-game advertising platform" (bring me back then kill me again), has signed deals with companies like EA and Hi-Rez (Smite) to try to bring TV-style commercials to their console games. Kotaku reports: Having tested this tech for over a year, they feel like it's now ready to be implemented, the idea being rather than just beaming videos to them in the middle of a game, players would be able to view an ad then, when servers detected the commercial had been viewed in its entirety, "release rewards to the player." This tech would be licensed out to developers so it could be implemented in the game itself (unlike the ads we already see on consoles, in places like system menu screens), and they're trying to justify it by saying that because young people are "cord-cutters," they're unreachable via traditional, cheaper marketing, and are only being reached by branded content deals (like the sneakers and clothes in NBA 2K, or cup noodles in Final Fantasy).

Testing has been taking place inside Smite for around a year, and the findings are as awful as you're probably expecting: "Data from one of Simulmedia's pilot campaigns with Smite, a F2P multiplayer battle arena game from Tencent's Hi-Rez Studios, shows that players were much more likely (22%) to play a game and spend money within the game (11%), if they watched in-game ads that gave them access to more gaming perks." As a result, playerWON "plans to launch in-game ads in roughly a dozen more games by the year's end."

An anonymous reader quotes a report from Ars Technica: Since the first Humble Indie Bundle launched to much acclaim in 2010, users have been able to allocate up to 100 percent of a bundle's pay-what-you-want purchase price to Humble's partner charities. That option will be going away in mid-July as the company institutes a new 15 to 30 percent minimum cut that will go to the storefront itself. If that new policy sounds familiar, it's probably because of a test Humble Bundle in April that hid the charity sliders from some customers as a form of early user testing. In light of negative feedback, Humble Bundle apologized for not being "more proactive in communicating the test." But at the time, the company also said it was planning to limit total charity donations to 15 percent of the user-set purchase price in the near future. By May, though, Humble Bundle backtracked and said it was leaving the charity sliders intact and turning them back on for all customers "while we take more time to review feedback and consider sliders and the importance of customization for purchases on bundle pages in the long term."

Today, that review seems to be over, and Humble Bundle has once again decided to set limits on the proportion of payments users can allocate to charity (though at a higher level than it publicly mulled back in April). In a blog post Thursday, the Humble Bundle team attributed the 15 to 30 percent minimum store cut (which will vary from bundle to bundle) to the fact that "the PC storefront landscape has changed significantly since we first launched bundles in 2010, and we have to continue to evolve with it to stay on mission." Humble Bundle says customers can still adjust their specific charitable giving within these new limits, and on-screen sliders will make any minimums clear. The team also argues that ensuring Humble Bundle itself makes some money from every bundle sale will "[let] us continue to invest in more exciting content so we can keep growing the Humble community, which will ultimately drive more donations for charitable causes."

Fifty years later, physicists at MIT and elsewhere have now confirmed Hawking's area theorem for the first time, using observations of gravitational waves. Their results appear today in Physical Review Letters. MIT reports: A central law for black holes predicts that the area of their event horizons -- the boundary beyond which nothing can ever escape -- should never shrink. This law is Hawking's area theorem, named after physicist Stephen Hawking, who derived the theorem in 1971. In the study, the researchers take a closer look at GW150914, the first gravitational wave signal detected by the Laser Interferometer Gravitational-wave Observatory (LIGO), in 2015. The signal was a product of two inspiraling black holes that generated a new black hole, along with a huge amount of energy that rippled across space-time as gravitational waves. If Hawking's area theorem holds, then the horizon area of the new black hole should not be smaller than the total horizon area of its parent black holes. In the new study, the physicists reanalyzed the signal from GW150914 before and after the cosmic collision and found that indeed, the total event horizon area did not decrease after the merger -- a result that they report with 95 percent confidence. Their findings mark the first direct observational confirmation of Hawking's area theorem, which has been proven mathematically but never observed in nature until now. The team plans to test future gravitational-wave signals to see if they might further confirm Hawking's theorem or be a sign of new, law-bending physics.

Russian spies accused of interfering in the 2016 U.S. presidential election have spent much of the past two years abusing virtual private networks (VPNs) to target hundreds of organizations worldwide, U.S. and British authorities said on Thursday. Reuters reports: The governments said in a joint advisory that Unit 26165, the arm of Russia's military spy agency whose officers were indicted for allegedly breaking into Democratic Party emails, had been using VPNs and Tor - a privacy-focused network - to conduct "widespread, distributed, and anonymized brute force access attempts against hundreds of government and private sector targets." The advisory did not identify any of the targets by name, saying only that they were mainly in the United States and Europe and included government offices, political parties, energy companies, law firms and media organizations. The National Security Agency (NSA) today also disclosed details of "brute force" methods they say have been used by Russian intelligence to try to break into the cloud services of hundreds of government agencies, energy companies and other organizations.

Earlier this week, law enforcement seized the servers and customer logs for DoubleVPN, a Russian-based VPN service that was reportedly used by cyber criminals to hide their activities while conducting ransomware attacks, phishing campaigns and other malicious hacking operations.
