  • China Releases First Homegrown Quantum Computing OS
    by BeauHD on 07/03/2026 at 10:00 am

    The Global Times reports: China's first domestically developed quantum computer operating system, Origin Pilot, has been made available for online download, the Global Times learned from the Anhui Quantum Computing Engineering Research Center on Wednesday. A Chinese scientist said while several quantum computing operating system efforts are underway worldwide, this is the first developed in China where it is seen as part of China's broad effort to achieve technology independence and to achieve technology advance in quantum computing. The center said the release marks the world's first open-source quantum computer operating system available for public download, which is expected to lower development barriers and support the growth of China's quantum computing ecosystem. Developed by Hefei-based Origin Quantum Computing Technology Co, the company behind China's third-generation superconducting quantum computer, Origin Wukong, Origin Pilot was first launched in 2021 and has gone through multiple rounds of iteration and upgrade. The developer describes it as an integrated quantum-classical-intelligent computing operating system compatible with major hardware approaches, including superconducting qubits, trapped ions and neutral atoms. It is now deployed on the company's Origin Wukong series and is available to external users, the company said. Guo Guoping, chief scientist of Origin Quantum and director at the Anhui Quantum Computing Engineering Research Center, told the Global Times that a quantum operating system is the "soft heart" of the quantum computing ecosystem. He said the decision to make Origin Pilot available globally marks a shift in China's quantum computing industry from closed-door tech innovation to broader open-source ecosystem development. Dou Menghan, head of the research team, said: "Users can quickly integrate with quantum chips of multiple physical types and, using autonomous programming frameworks such as QPanda, execute quantum computing jobs across different physical quantum chips to support both research and commercialization needs."

  • Asteroid 2024 YR4 Will Not Impact the Moon
    by BeauHD on 07/03/2026 at 7:00 am

    Ancient Slashdot reader alanw shares a report from the European Space Agency (ESA): Last year, an approximately 60 meter near-Earth object captured global attention. For a brief period, asteroid 2024 YR4 became the most dangerous asteroid discovered in the last 20 years. While an Earth impact was soon ruled out, the asteroid faded from view with a lingering 4% chance of striking the Moon on 22 December 2032. Now, that risk has been eliminated. Astronomers have confirmed that 2024 YR4 will not impact the Moon using new observations made by the Near-Infrared Camera (NIRCam) on the NASA/ESA/CSA James Webb Space Telescope. Instead, it will safely pass the Moon at a distance of more than 20 000 km. Read more of this story at Slashdot.

  • Humanity Heating Planet Faster Than Ever Before, Study Finds
    by BeauHD on 07/03/2026 at 3:00 am

    An anonymous reader The Guardian: Humanity is heating the planet faster than ever before, a study has found. Climate breakdown is occurring more rapidly with the heating rate almost doubling, according to research that excludes the effect of natural factors behind the latest scorching temperatures. It found global heating accelerated from a steady rate of less than 0.2C per decade between 1970 and 2015 to about 0.35C per decade over the past 10 years. The rate is higher than scientists have seen since they started systematically taking the Earth's temperature in 1880. "If the warming rate of the past 10 years continues, it would lead to a long-term exceedance of the 1.5C (2.7F) limit of the Paris agreement before 2030," said Stefan Rahmstorf, a scientist at the Potsdam Institute for Climate Impact Research and co-author of the study. [...] The researchers applied a noise-reduction method to filter out the estimated effect of nonhuman factors in five major datasets that scientists have compiled to gauge the Earth's temperature. In each of them, they found an acceleration in global heating emerged in 2013 or 2014. The findings have been published in the journal Geophysical Research Letters.

  • Trump Administration Says It Can't Process Tariff Refunds Because of Computer Problems
    by BeauHD on 07/03/2026 at 1:00 am

    U.S. Customs and Border Protection (CBP) said in a filing on Friday that it currently cannot process billions in tariff refunds because its import-processing system is "not well suited to a task of this scale." The Verge reports: The CBP's admission comes after the Supreme Court struck down the tariffs imposed by Trump under the International Emergency Economic Powers Act (IEEPA) last month. This week, the International Trade Court ruled that importers impacted by the tariffs are entitled to refunds with interest. The CBP estimates that it collected around $166 billion in IEEPA duties as of March 4th, 2026. [...] The CBP says it currently processes imports through its Automated Commercial Environment (ACE) system. In the filing, Lord says that using the department's existing technology, it would take more than 4.4 million hours to process refunds for the over 53.2 million entries with IEEPA duties. Despite these current limitations, the CBP says it's "confident" it can develop and launch new capabilities to "streamline and consolidate refunds and interest payments on an importer basis" -- but this could take 45 days. "The process will be simpler and more efficient than the existing functionalities, and CBP will provide guidance on how to file refund declarations in the new system," Lord says.

  • Oura Buys Gesture-Navigation Startup DoublePoint
    by BeauHD on 06/03/2026 at 11:00 pm

    Smart ring maker Oura has acquired Doublepoint, a Finnish startup specializing in gesture recognition technology for wearables. Engadget reports: The Finnish startup uses smartwatches and wristbands as examples of products that benefit from its technology, but Oura will clearly be looking to incorporate it into its rings, in theory allowing you to control your connected devices with hand movements. Oura said in a press release that the deal sees it inherit an "exceptional team of AI architects and builders from Doublepoint," including Doublepoint's four founders. The newly-acquired company will remain in its native Helsinki, where it will work with Oura's international teams. It added that Doublepoint's expertise in helping devices register subtle hand movements will be key, as nobody wearing a smart ring is going to engage with gesture control if they have to thrash their hand around like a conductor.

  • Apple Blocks US Users From Downloading ByteDance's Chinese Apps
    by BeauHD on 06/03/2026 at 10:00 pm

    An anonymous reader quotes a report from Wired: While TikTok operates in the United States under new ownership, Apple has deployed technical restrictions to block iOS users in the United States from downloading other apps made by the video platform's Chinese parent organization ByteDance. ByteDance owns a vast array of different apps spanning social media, entertainment, artificial intelligence, and other sectors. The leading one is Douyin, the Chinese version of TikTok, which has over 1 billion monthly active users. While most of those users reside in China, iPhone owners around the world have traditionally been able to download these apps from anywhere without using a VPN, as long as they have a valid App Store account registered in China. That's not true anymore. Starting in late January, iPhone users in the U.S. with Chinese App Store accounts began reporting that they were encountering new obstacles when they tried to download apps developed by ByteDance. WIRED has confirmed that even with a valid Chinese App Store account, downloading or updating a ByteDance-owned Chinese app is blocked on Apple devices located in the United States. Instead, a pop-up window appears that says, "This app is unavailable in the country or region you're in." The restriction appears to apply only to ByteDance-owned apps and not those developed by other Chinese companies. The timing and technical specifics suggest the restriction is related to the deal TikTok agreed to in January to divest Chinese ownership of its U.S. operations. The agreement was the result of the so-called TikTok ban law passed by Congress in 2024, which also barred companies like Apple and Google from distributing other apps majority-owned by ByteDance. The Protecting Americans from Foreign Adversary Controlled Applications Act states that no company can "distribute, maintain, or update" any app majority-controlled by ByteDance "within the land or maritime borders of the United States." The law was primarily aimed at TikTok, which has more than 100 million users in the U.S. and had been the subject of years of debate in Washington over whether its Chinese ownership posed a national security risk. But ByteDance also has dozens of other apps that at some point were also removed from Apple's and Google's app stores in the U.S.. Now it seems like the scope of impact has reached even more apps that are not technically designed for U.S. audiences, such as Douyin, the AI chatbot Doubao, and the fiction reading platform Fanqie Novel.
