  • China's EV Price War Was Built On Cars Sold At a Loss
    by BeauHD on 18/06/2026 at 7:00 am

    Longtime Slashdot reader schwit1 shares a report from Autoblog: For years, the Chinese auto industry has employed a hostile price war to kneecap global competitors. Armed with massive state subsidies, cheap raw materials, and an aggressive "scale-first" business model, Chinese automakers flooded the market with electric vehicles priced so low that legacy manufacturers stood no chance to compete. How did they do it? Simple, they couldn't. They did it anyway. Reports from CarNewsChina show that Chinese automakers have been selling vehicles at a loss until a recent law passed by the Chinese government banned below-cost sales of new vehicles. During the ongoing sales slump in China caused by rolled-back subsidies and direct government intervention banning below-cost sales, the truth behind the rapid expansion of the Chinese auto industry has been exposed. "By the first quarter of 2026, China captured 32 percent of the global auto market, with its New Energy Vehicles (NEVs) controlling an incredible 61 percent of global share," the report notes. Yet that dominance has come at a steep cost: throughout 2025, "the profit margin for China's auto industry plunged to 4.4 percent and dropped further to a historic low of 3.2 percent in early 2026." "Gross profit, not net profit, per vehicle, plummeted to a mere $2,000. We can expect the net figure to be loss-making." Autoblog adds: "Data shows over 70 percent of Chinese car sales were loss-making. This left more than half of the country's auto industry in the red. Great Wall Motor (GWM) even saw net profits drop 17 percent despite steady revenue growth." China's EV price war has now hit a wall. New regulations are discouraging below-cost sales, rising material costs are forcing automakers to cut discounts and raise prices, and reduced tax incentives are weakening domestic demand. To sustain growth, manufacturers are increasingly turning to exports. Read more of this story at Slashdot.

  • Tesco Moving 40,000 Server Workloads Off VMware Amid Broadcom's 'Abusive Conduct'
    by BeauHD on 18/06/2026 at 3:30 am

    An anonymous reader quotes a report from Ars Technica: Tesco, a retail conglomerate headquartered in the United Kingdom, is moving 40,000 server workloads off of VMware amid "abusive conduct" from Broadcom, recent legal filings claim. Tesco filed a lawsuit in the UK's High Court against Broadcom alleging breach of contract last year. According to a September report from The Register, the lawsuit claimed that in January 2021, Tesco bought perpetual licenses for VMware's vSphere Foundation and Cloud Foundation, a subscription to VMware Tanzu, plus support services until 2026, with the option to extend support for four additional years. But when Broadcom took over VMware in November 2023, it would not honor the deal and instead tried to get Tesco to pay "excessive and inflated prices for virtualization software for which Tesco has already paid" and would not allow it to buy support services for its perpetually licensed software without buying "duplicative subscription-based licenses for those same Software products," the initial complaint read, The Register reported at the time. Tesco, which reported 73.7 billion pounds (about $98.7 billion) in revenue in its fiscal year 2026, has since started migrating away from VMware and Broadcom's mainframe products, according to late-May court filings reported on by The Register today. In January, Broadcom stopped supporting Tesco's VMware products, Tesco said, and Tesco has been paying for third-party support since. In its initial filing, Tesco also said that Broadcom refused to upgrade software or provide all security updates to customers without subscriptions. One of Tesco's recent filings, per The Register, reads: "Faced with Broadcom's abusive conduct, and given the criticality of virtualization and mainframe software and services to its business, Tesco has been forced to incur material costs to procure alternative solutions with reduced functionality, and to migrate to that software in a manner, and on a timeframe, that creates very significant risks to its business." If it works "at exceptional pace," Tesco will be completely off VMware by the end of 2027 at the earliest. However, "the timeframe in which that migration must be undertaken has created and continues to create operational and commercial risk, and at material ongoing cost and disruption to the business," Tesco reportedly noted. Tesco is also dealing with migration challenges related to data security because its new, unnamed virtualization software is incompatible with the Veeam and Zerto products it uses. Tesco initially requested at least 100 million pounds (about $133.6 million) in damages each from Broadcom, VMware, and reseller Computacenter, plus interest. In its recent filings, Tesco said it turned down at least four offers from Broadcom to continue using VMware and Broadcom's mainframe tech. [...] The case is expected to go to court between November 1, 2027, and February 25, 2028, The Register reported. Afterward, it could go to trial.

  • Microsoft Working To Patch 'RoguePlanet' Zero-Day
    by BeauHD on 17/06/2026 at 11:00 pm

    wiredmikey shares a report from SecurityWeek: Microsoft on Wednesday published an advisory acknowledging the public disclosure of a vulnerability in Defender that could lead to privilege escalation. The security defect, tracked as CVE-2026-50656 (CVSS score of 7.8), was dropped last week by security researcher Nightmare Eclipse (also known as Chaotic Eclipse). "We are working to provide a high-quality security update that addresses this vulnerability. We will provide information in this CVE when the update is available," Microsoft adds. RoguePlanet, Nightmare Eclipse explained last week, targets a race condition in Microsoft Defender and allows attackers to gain System privileges. The researcher released a proof-of-concept (PoC) exploit that demonstrates local privilege escalation (LPE) on Windows 11 and Windows 10 systems with the June 2026 patches installed. [...] On Wednesday, Nightmare Eclipse pointed out that the PoC works regardless of whether Defender's real-time protection is enabled or disabled. It may even work in passive mode, the researcher said. Read more of this story at Slashdot.

  • Smartphone Market To Shrink 15% This Year Due To Memory Crisis
    by BeauHD on 17/06/2026 at 10:00 pm

    CCS Insight expects global smartphone shipments to fall 15% this year as AI-driven demand pushes memory manufacturers toward higher-margin server chips. "[S]ome entry-level devices have already seen their sticker prices go up by more than 50 percent since last year," reports The Register. From the report: The firm found that the primary smartphone market (meaning new devices) contracted 4.4 percent in the first quarter of this year, despite sales channels front-loading (meaning stockpiling) product inventory, as device prices begin to rise sharply. As CCS notes, this casts an ominous shadow on the outlook for the rest of the year, and it seems things have worsened since The Register first started reporting on the smartphone memory woes. Back in January, the forecast was for handset price rises of 6-8 percent, while the most pessimistic outlook was that the global market might contract as much as 5.2 percent. By February, analysts were expecting to see a decline in shipments of around 8 percent across the global market, and for prices to increase by about 14 percent. The root cause of all this is the AI craze, which has seen huge demand for high-performance GPU-filled servers to process it all. Chipmakers have moved to capitalize on this by prioritizing production of high-margin memory components for those servers, rather than making the plain old DRAM and NAND needed for PCs and phones. "The memory chip crisis shows no sign of slowing down in the near future, ramping up the pressure on manufacturers and consumers. Memory components now account for more than 30 percent of a manufacturer's bill of materials in some smartphones." said CCS research analyst Ben Hatton. "The full impact has yet to be felt in many regions, but it's clear that device prices will accelerate over the rest of the year." Read more of this story at Slashdot.

  • Carvana Is Turning Dealerships Into 'Playgrounds,' Test-Drive Centers With Sales All Online
    by BeauHD on 17/06/2026 at 9:00 pm

    Carvana is testing a radically different new-car dealership model in Dallas, turning the location into a test-drive center and themed "playground" while requiring every purchase to be completed through its online platform. "Every single car that we sell, whether it's used or new, is online," said Tom Taira, Carvana president of special projects who's leading the new vehicle operations. "That's a very inherent difference. Even coming into the store, you're buying it online, and that's a big difference in how people think about it." The company hopes its no-haggle pricing, hourly employees, service operations, and national logistics network can reshape franchised auto retail. CNBC reports: Through its used vehicles sales, Carvana has become the most valuable auto retailer in the U.S. with a more than $70 billion market cap. Carvana's target with the new vehicle business is to grow its market share and customer base as well as assist used vehicle sales through trade-ins and other means, according to Taira. If the company is successful, the strategy could cause a ripple effect across the U.S. franchised dealership model, which the National Automobile Dealers Association reports includes 16,990 retailers that topped $1.3 trillion in sales last year. [...] Carvana is using a location in Dallas as a test center for its foray into new vehicle sales. The facility looks like a traditional Stellantis dealership from the outside, but the consumer process for purchasing a vehicle and the responsibilities of its employees are unprecedented. Couches and chairs replace cubicles and sales offices. There are no finance and insurance departments, and instead of an army of commission-based employees, the facility has associates that are paid hourly to assist customers -- if they want the help. The experience is meant to be as self-guided as a customer wants. By scanning QR codes located on 10-foot-by-10-foot screens inside the building or on vehicles and displays outside, shoppers can customize a vehicle, learn about a product's features and conduct test drives before deciding whether to purchase anything. If they do decide to buy something, it's online and not originated from a sales person, the company said. The "playground" has roughly 50 vehicles divided by brand, with each having a theme. Jeep has an off-road display. Dodge has race tracks, including a Carvana-themed Charger pace car and part of a traditional track fence barrier. Chrysler minivans, meanwhile, have a soccer net and Ram's area is truck-centric. Carvana is not committing to expanding the exact experience to its other franchised dealer locations, but Taira told CNBC that the overall process of online sales, vehicle testing and service are expected to be consistent throughout the locations.

  • Google, Microsoft, and OpenAI Back Linux Foundation's Appia AI Standards Initiative
    by BeauHD on 17/06/2026 at 8:03 pm

    BrianFagioli writes: Google, Microsoft, OpenAI, Arm, Mastercard, Siemens, and other companies have joined the newly launched Appia Foundation under the Linux Foundation. The project aims to create common specifications and assessment frameworks that organizations can use to demonstrate AI systems meet emerging safety, trust, and compliance requirements. According to the Linux Foundation, the framework is designed to allow conformity evidence to be reused across the AI supply chain, potentially reducing duplicate assessments and compliance costs. The announcement comes as governments around the world move toward enforcing AI regulations and organizations face increasing pressure to prove AI systems are trustworthy. "As international standards and legal frameworks become more established, global organizations need a consistent, practical way to verify that AI systems conform to new expectations," said Jim Zemlin, CEO of the Linux Foundation. "The Appia Foundation establishes a neutrally governed environment where the entire industry can collaborate on a common assessment framework. By building this infrastructure in the open, we are helping organizations reduce complexity, lower operational costs and build trust." Craig Shank, Executive Director of the Appia Foundation, added: "AI systems now make decisions about people's loans, their children's schools and their jobs. People on the receiving end deserve to know those systems were built and assessed against criteria that hold up to scrutiny. The Appia Foundation was formed to do that work: creating publicly available specifications that organizations across the AI value chain use to demonstrate their systems meet those criteria. By establishing this open framework, we are building the accountability layer required to scale safe and trusted AI across major industries." Read more of this story at Slashdot.
