Donald Trump's crypto company created a digital dollar called USD1, which is now being used by a big investor in Abu Dhabi to help fund a $2 billion deal with Binance, the world's largest crypto exchange. Reuters reports: Stablecoins are an increasingly lucrative cog in global crypto trading. Their issuers typically profit by earning interest from the Treasuries and other assets that underpin them. The value of USD1 in circulation reached about $2.1 billion on Wednesday, according to CoinMarketCap data, making it one of the fastest-growing stablecoins. The identity of its major holders, however, remains unclear. An anonymous cryptocurrency wallet that holds $2 billion worth of USD1 received the funds between April 16 and 29, according to data from crypto research firm Arkham. Reuters could not ascertain the owner of this wallet. Binance founder and former CEO Changpeng Zhao, who was incarcerated in the United States last year after pleading guilty to violating U.S. laws against money laundering, met Zach Witkoff and two other World Liberty co-founders in Abu Dhabi, according to a photo posted on social media site X on Sunday. "It was great to see our friends," in Abu Dhabi, posted Zhao in response to the photo, tagging Witkoff. Zhao, who in 2023 stepped down from his role at Binance as part of a $4.3 billion settlement with the U.S. over the illicit finance charges, remains a major shareholder of Binance. Separately, Zach Witkoff announced that USD1 would be integrated into Tron, the blockchain of Hong Kong-based crypto entrepreneur Justin Sun. Sun is the biggest known investor in World Liberty and an adviser to the venture, according to his social media posts, having poured at least $75 million into the project. Sun was fighting a U.S. securities fraud lawsuit at the time of his first investment in World Liberty. The U.S. Securities and Exchange Commission in February paused its case against him, citing public interest.

Following a major court ruling limiting Apple's control over App Store payments, Patreon plans to update its iOS app to allow payments outside Apple's system, letting creators keep more of their earnings. Spotify and Proton are also preparing similar updates. The Verge reports: "This is a huge moment for creators and their businesses," [spokesperson Adiya Taylor] says. "The iOS app is the number one platform for fan engagement on Patreon, and we believe this ruling allows creators to get paid without giving Apple 30 percent. As a first step, we will submit an app update for review by Apple to enable payments outside of IAP so creators keep more from iOS based fan payments." Last year, Patreon said it was forced to switch to Apple's in-app purchase system, which applied a 30 percent fee to all new memberships purchased in the app, or else risk "being removed from the App Store." "When we first announced rolling out Apple's IAP requirements last year, we shared that we used three principles to guide our decision in how we wanted to move forward: transparency, control, and stability," Taylor says. "Keeping with those principles, we're exploring further action we can take, and we'll continue to keep creators and fans posted on any changes to our experience." Taylor wasn't able to share a timeline for when the update might be rolled out. Further reading: Epic Games Is Launching Webshops To Circumvent App Store Fees

An anonymous reader quotes a report from TechCrunch: Epic Games is taking a victory lap. After notching a big win against Apple in a years-long legal dispute, Epic announced that its Epic Games Store will allow developers to open webshops, which can offer players out-of-app purchases to circumvent fees from Apple and Google. [...] With the Epic Games Store's new webshops feature, other developers will be more easily able to follow suit. Usually, Epic takes a 12% share of a developer's earnings from the Epic Games Store, which is still a better deal than what developers get from Apple. But starting in June, Epic Games will not take a cut from the first $1 million each game earns annually. Only after a game eclipses $1 million in revenue will Epic begin taking a cut. "With new legal rulings in place, developers will be able to send players from games to make digital purchases from webshops on any platform that allows it, including iOS in the European Union and United States," Epic said.

Meta's Reality Labs posted a $4.2 billion operating loss in Q1 2025. According to CNBC, cumulative losses since 2020 now exceed $60 billion. From the report: Meta's Reality Labs unit is responsible for the company's Quest-branded virtual reality headsets and Ray-Ban Meta Smart Glasses. It's the key business unit that anchors CEO Mark Zuckerberg's plans to build a new computing platform involving digital worlds accessible via VR and augmented reality devices. [...] Wall Street has questioned Meta's big spending on the metaverse, which Zuckerberg has said could take many years to turn into a real business. The company must now also contend with sweeping new tariffs from President Donald Trump and the likely increase in costs that will follow, potentially leading to higher-priced devices. Last week, Meta said that an unspecified number of Reality Labs employees were laid off. Those workers were part of the Oculus Studios unit, which creates VR and AR games and content for Quest VR headsets.

Sam Altman's eye-scanning identity project, now called World, officially launched in the U.S. with six in-person registration sites. CNBC reports: Here's how it works: You go up to an Orb, a spherical biometric device, and it spends about 30 seconds scanning your face and iris, then creates and stores a unique "IrisCode" for you verifying that you're a human and that you've never signed up before. Then you get some of the project's cryptocurrency, WLD, for free, and you can use your World ID as a sign-in with integrated platforms, which currently include an open API integration with Minecraft, Reddit, Telegram, Shopify and Discord. Starting Thursday, the company is opening six flagship U.S. retail locations where people can sign up to have their eyeball scanned: Austin, Atlanta, Los Angeles, Nashville, Miami and San Francisco. At an event in San Francisco on Wednesday, the venture announced two high-profile partnerships: Visa will introduce the "World Visa card" this summer, available only to people who have had their irises scanned by World, and the online dating giant Match Group will begin a pilot program testing out World ID and some age verification tools with Tinder in Japan.

An anonymous reader quotes a report from CBS News: The House of Representatives on Thursday voted to block California from implementing plans to block new sales of gas-powered vehicles in a decade. In a 246-164 vote, members approved House Joint Resolution 88, which seeks to withdraw a waiver granted by the Environmental Protection Agency to California during the Biden administration to implement the ban. Thirty-five Democrats joined 211 Republicans in backing the measure. [...] The House also approved two other measures which withdraw waivers on the state's plans to increase sales of zero-emissions trucks in a 231-191 vote, along with the state's latest nitrogen oxide emission standards for engines in a 225-196 vote. Following Thursday's vote, Newsom's office issued a statement saying the House illegally used the Congressional Review Act (CRA) to repeal the state's Clean Air Act waivers. The governor's office also said the move contradicts the Government Accountability Office and Senate Parliamentarian who have ruled the CRA does not apply to the state's waivers. "Trump Republicans are hellbent on making California smoggy again. Clean air didn't used to be political. In fact, we can thank Ronald Reagan and Richard Nixon for our decades-old authority to clean our air," Newsom said. "The only thing that's changed is that big polluters and the right-wing propaganda machine have succeeded in buying off the Republican Party -- and now the House is using a tactic that the Senate's own parliamentarian has said is lawless. Our vehicles program helps clean the air for all Californians, and we'll continue defending it." Sen. Alex Padilla (D-California) said in a statement: "House Republicans' misguided and cynical attempts to gut the Clean Air Act and undercut California's climate leadership ignores the reality of California's strength as the fourth largest economy in the world... ... If Senate Republicans take up these measures under the Congressional Review Act, they will be going nuclear by overruling the Parliamentarian, all to baselessly attack California."

Nature: A forthcoming policy from the US National Institutes of Health (NIH) will target - and at least temporarily stop -- funding to laboratories and hospitals outside the United States, threatening thousands of global-health projects and international collaborations on topics such as emerging infectious diseases and cancer. The NIH, the world's largest funder of biomedical research, plans to release the policy in the next week. Some agency staff members have already been instructed to hold funds for foreign institutions that are part of both new research grants and grants coming up for renewal, according to multiple agency employees who spoke to Nature under the condition of anonymity because they are not authorized to speak to the press.

Chinese scientists have achieved a significant nuclear breakthrough by successfully refueling a thorium-based reactor while it remains operational, according to reports from Chinese state media. The experimental 2-megawatt thermal reactor, which came online in June 2024, represents the revival of technology originally developed and abandoned by the United States in the mid-20th century. The milestone was revealed during a closed meeting at the Chinese Academy of Sciences, where project leaders shared results demonstrating the reactor's ability to be refueled without shutdown -- a capability conventional uranium reactors lack. Though small compared to MIT's 6-megawatt research reactor, this achievement shows China's accelerating nuclear ambitions. The country has surpassed France in nuclear generation and recently approved 10 new reactors worth over $27 billion in investment. This thorium reactor joins other revived nuclear concepts, including molten-salt cooling systems and high-temperature gas reactors, as developers look to the past for solutions to advance nuclear energy's future.

A "small percentage" of Google's users in the US will begin seeing an AI Mode tab in Google Search "in the coming weeks," the company said Thursday, marking the tool's first deployment outside the company's experimental Labs environment. Unlike traditional search results that display URLs based on user queries, AI Mode generates conversational responses from Google's search index. The feature will appear as a dedicated tab positioned before the standard "All," "Images," and other search filters. The deployment represents Google's direct challenge to LLM-powered search engines like Perplexity and ChatGPT. AI Mode differs from existing AI Overviews in Google Search, which merely insert AI summaries between the search box and web results.

Amazon CEO Andy Jassy has this week sounded the alarm on AI adoption speeds. Though self-described as an AI optimist, Jassy cautioned that this technological shift "may be quicker than other technology transitions in the past." Jassy pointed directly to declining education quality as "one of the biggest problems" facing AI implementation, not the technology itself. He questioned whether schools are adequately preparing students for future tool use, including coding applications.

Nvidia publicly criticized AI startup Anthropic on Thursday over claims about Chinese smuggling tactics, just days before the Biden-era "AI Diffusion Rule" takes effect on May 15. The confrontation highlights growing tensions between AI hardware providers and model developers over export controls. "American firms should focus on innovation and rise to the challenge, rather than tell tall tales that large, heavy, and sensitive electronics are somehow smuggled in 'baby bumps' or 'alongside live lobsters,'" an Nvidia spokesperson said, responding to Anthropic's Wednesday blog post. The Amazon and Google-backed AI startup had called for tighter restrictions and enforcement, arguing that "maintaining America's compute advantage through export controls is essential for national security." Anthropic specifically proposed lowering export thresholds for Tier 2 countries to prevent China from gaining ground in AI development. Nvidia countered that policy shouldn't be used to limit competitiveness: "China, with half of the world's AI researchers, has highly capable AI experts at every layer of the AI stack. America cannot manipulate regulators to capture victory in AI."

An anonymous reader shares a report: A new paper from AI lab Cohere, Stanford, MIT, and Ai2 accuses LM Arena, the organization behind the popular crowdsourced AI benchmark Chatbot Arena, of helping a select group of AI companies achieve better leaderboard scores at the expense of rivals. According to the authors, LM Arena allowed some industry-leading AI companies like Meta, OpenAI, Google, and Amazon to privately test several variants of AI models, then not publish the scores of the lowest performers. This made it easier for these companies to achieve a top spot on the platform's leaderboard, though the opportunity was not afforded to every firm, the authors say. "Only a handful of [companies] were told that this private testing was available, and the amount of private testing that some [companies] received is just so much more than others," said Cohere's VP of AI research and co-author of the study, Sara Hooker, in an interview with TechCrunch. "This is gamification." Further reading: Meta Got Caught Gaming AI Benchmarks.

An anonymous reader writes: NIH Director Dr. Jay Bhattacharya has announced that the NIH Public Access Policy, originally slated to go into effect on December 31, 2025, will now be effective as of July 1. From Bhattacharya's announcement: NIH is the crown jewel of the American biomedical research system. However, a recent Pew Research Center study shows that only about 25% of Americans have a "great deal of confidence" that scientists are working for the public good. Earlier implementation of the Public Access Policy will help increase public confidence in the research we fund while also ensuring that the investments made by taxpayers produce replicable, reproducible, and generalizable results that benefit all Americans. Providing speedy public access to NIH-funded results is just one of the ways we are working to earn back the trust of the American people. Trust in science is an essential element in Making America Healthy Again. As such, NIH and its research partners will continue to promote maximum transparency in all that we do.

Just a day after announcing its shift to an "AI-first" strategy -- which includes phasing out contract workers in favor of automation -- Duolingo revealed it is more than doubling its course offerings by launching 148 new language courses. The Verge reports: The company said today that it's launching 148 new language courses. "This launch makes Duolingo's seven most popular non-English languages -- Spanish, French, German, Italian, Japanese, Korean, and Mandarin -- available to all 28 supported user interface (UI) languages, dramatically expanding learning options for over a billion potential learners worldwide," the company writes. Duolingo says that building one new course historically has taken "years," but the company was able to build this new suite of courses more quickly "through advances in generative AI, shared content systems, and internal tooling." The new approach is internally called "shared content," and the company says it allows employees to make a base course and quickly customize it for "dozens" of different languages. "Now, by using generative AI to create and validate content, we're able to focus our expertise where it's most impactful, ensuring every course meets Duolingo's rigorous quality standards," Duolingo's senior director of learning design, Jessie Becker, says in a statement.

The European Space Agency has launched the Biomass satellite to study the world's forests using the first space-based P-band synthetic aperture radar, aiming to accurately measure carbon storage and improve understanding of the global carbon cycle. CBS News reports: Forests on Earth collectively absorb and store about 8 billion tons of carbon dioxide annually, the ESA said. That regulates the planet's temperature. Deforestation and degradation, especially in tropical regions, means that stored carbon is being released back into the atmosphere, the ESA said, which can contribute to climate change. There's a lack of accurate data on how much carbon the planet's estimated 1.5 trillion trees store and how much human activity can impact that storage, the ESA said. To "weigh" the planet's trees and determine their carbon dioxide capacity, Biomass will use a P-band synthetic aperture radar. It's the first such piece of technology in space. The radar can penetrate forest canopies and measure woody biomass, including trunks, branches and stems, the ESA said. Most forest carbon is stored in these parts of the trees. Those measurements will act as a proxy for carbon storage, the ESA said. [...] Once the radar takes the measurements, the data will be received by the large mesh reflector. It will then be sent to the ESA's mission control center.

For testing networking systems, load simulators are useful: send a bunch of realistic looking traffic and see what happens as you increase the amount of sent traffic. These sorts of simulators often rely on being heavily multithreaded, since one computer can, if pushed, generate a lot of network traffic.

Thus, when Jonas inherited a heavily multithreaded system for simulating load, that wasn't a surprise. The surprise was that the developer responsible for it didn't really understand threading in Java. Probably in other languages too, but in this case, Java was what they were using.

public void startTraffic() { Configuration.instance.inititiateStatistics(); Statistics.instance.addStatisticListener(gui); if (t != null) { if (t.isAlive()) { t.destroy(); } } t = new Thread(this); t.start(); }

Look, this is not a good way to manage threads in Java. I don't know if I'd call it a WTF, but it's very much a "baby's first threading" approach. There are better abstractions around threads that would avoid the need to manage thread instances directly. I certainly don't love situations where a Runnable also manages its own thread instance.

This is almost certainly a race condition, but I don't know if this function is called from multiple threads (but I suspect it might be).

But what's more interesting is where this code gets called. You see, starting a thread could trigger an exception, so you need to handle that:

public void run() { while (true) { try { loaderMain.startTraffic(); break; } catch (Exception e) { System.out.println("Exception in main loader thread!"); e.printStackTrace(); } } }

Inside of an infinite loop, we try to start traffic. If we succeed, we break out of the loop. If we fail, well, we try and try again and again and again and again and again and again…

Jonas writes:

Since I'm the only one that dares to wade through the opaque mess of code that somehow, against all odds, manages to work most of the time, I get to fix it whenever it presents strange behavior.

I suspect it's going to present much more strange behavior in the future.

Apple violated a court order requiring it to open up the App Store to third-party payment options and must stop charging commissions on purchases outside its software marketplace, a federal judge said in a blistering ruling that referred the company to prosecutors for a possible criminal probe. From a report: U.S. District Judge Yvonne Gonzalez Rogers sided Wednesday with "Fortnite" maker Epic Games over its allegation that the iPhone maker failed to comply with an order she issued in 2021 after finding the company engaged in anticompetitive conduct in violation of California law. Gonzalez Rogers also referred the case to federal prosecutors to investigate whether Apple committed criminal contempt of court for flouting her 2021 ruling. The U.S. attorney's office in San Francisco declined to comment. The changes the company must now make could put a sizable dent in the double-digit billions of dollars in revenue the App Store generates each year. The judge's order [PDF]: Apple willfully chose not to comply with this Court's Injunction. It did so with the express intent to create new anticompetitive barriers which would, by design and in effect, maintain a valued revenue stream; a revenue stream previously found to be anticompetitive. That it thought this Court would tolerate such insubordination was a gross miscalculation. As always, the cover-up made it worse. For this Court, there is no second bite at the apple. It Is So Ordered.
