Fabled RepairTuber and right to repair crusader Louis Rossmann has shared a new video encapsulating his surprise, and disappointment, that Brother has morphed into an “anti-consumer printer company.” More information about Brother’s embrace of the dark side are shared on Rossmann’swiki, with the major two issues being new firmware disabling third party toner, and preventing (on color devices) color registration functionality. Rossmann is clearly perturbed by Brother’s quiet volte-face with regard to aftermarket ink....

A macOS user discovered that the latest M4 Apple silicon does not support visualization of operating systems prior to macOS 13.4 Ventura, which was released in May 2023. When the user tried loading older versions of macOS, the virtual machine failed to load, with the display showing a black screen. They even tried to create the virtual machine (VM) directly on the M4 Mac, which was successful at first, but eventually resulted in the same black screen, according toThe Eclectic Light Company....

On Saturday, the Cyberspace Administration of China announced a likely-to-be-enforced draft plan to enforce mandatory red-flagging of all generative AI content posted online in China [h/tThe Register]. Flagging methods include audible disclaimers inaudiofiles, visible watermarks in images, and notices spread throughout the video. Users who don’t flag their AI content may still have it flagged anyway, based on metadata or its absence. The primary purpose of this being a “draft” plan until October, despite the fact that China will enforce this as it pleases, seems to be to give platforms a chance to prepare since the public comments will likely not factor into the final version of this plan....

Chip imports to China have seen a historic drop year-over-year, with the value of imports in 2023 falling by 15.4% according toBloomberg. Chip sales were down across the board in 2023 thanks to a weakening global economy, but China’s chip imports indicate that its economy might be in trouble. The country’s inability to import cutting-edge silicon is also certainly a factor in its decreasing chip imports. In 2022, the value of chip imports to China stood at $413 billion, and in 2023 the country only imported chips worth a total of $349 billion, a 15....

ChangXin Memory Technologies (CXMT) had to delay mass production of its DDR5 memory devices in a bid to improve quality to late 2025, reportsDigitimes. However, it looks like the quality of the company’s DDR5 ICs is now on par with that of Nanya, according to the same report. The combination of improved yields, quality, and CXMT’s expanding production capacity can make not only smaller Taiwan-based vendors, but also global players worry about CXMT’s impact on the market....

Hua Hong Semiconductor, China’s second-largest chip foundry, has made strategic leadership changes to prioritize logic chip production and develop more advanced process technologies. The company hired Bai Peng, a veteran in logic chip technology, and appointed him president on June 27, 2025, reportsNikkei. Bai Peng, who spent over three decades at Intel and led logic chip development from research to mass production, is expected to steer Hua Hong’s shift toward advanced semiconductor production technologies....

Unisoc, formerly Spreadtrum, a well-known developer of various application processors from China, has introduced what it claims to be the world’s firstsecuritychip based on RISC-V, an open instruction set architecture (ISA). The E450R is said to offer significant performance for security algorithms, reportsIT Home. The key feature of the E450R is its asymmetric cryptographic PKE algorithm engine, which is said to work 50% faster than on the predecessor. Even when the key length is increased, the chip maintains its performance, ensuring robust security without sacrificing speed, according to the source report....

Why you’re able to trust Tom’s HardwareOur expert reviewers spend hours testing and comparing products and services so you can choose the best for you.Find out more about how we test. Benchmarks and Conclusion CPU-only thermal results with PBO enabled: AMD Ryzen 9 9950X3D Without power limits enforced, the hottest CPUs on the market will hit their peak temperature (TJ Max) and thermally throttle with even the strongest of air coolers and even most liquid coolers on the market in intensive stress testing....

PC overclocking and hardware expert Roman ‘Der8auer’ Hartung has shared his before-and-afterAMD Ryzen 9 9950X3Ddelidding test results. His conclusion: enthusiasts can expectup to 10% higher performancewith direct-die cooling, but the cost will be significantly higher power consumption. Alternatively, Der8auer observed that users could run the delidded CPU at stock settings and enjoy far lower temperatures, around 23 degrees Celsius lower in this case, plus improved efficiency. A comfortable compromise might be found between these sampled extremes....

Elon Musk has announced that xAI’sGrok 3large language model (LLM) has been pretrained, and took 10X more compute power than Grok 2. He did not reveal many details, but based on timing, the Grok 3 LLM was pre-trained on the Colossus supercluster, which contains some 100,000 NvidiaH100GPUs. “Grok 3 is coming soon,” Elon Muskwrote in an X post. “Pretraining is now complete with 10X more compute than Grok 2.” Given the timing and context, this confirms previous reports that xAI’sColossus supercomputer, which boasts around 100,000 Nvidia H100 GPUs, was specifically built to accelerate large-scale AI projects....

One of the surprises brought by Intel’s launch ofArc B580 and Arc B570graphics cards was the emergence of a new add-in-boards (AIB) brand: Onix. New players rarely arrive in the AIB market due to cutthroat competition and diminishing margins. However, Onix (viaBenchLife) is reportedly not a newbie but a brand belonging to Sapphire, a veteran with a history spanning over 20 years. Apparently, Onix Technology Limited was registered in Hong Kong on May 23, 2025....

According toVideoCardz, Nvidia partner Palit is getting ready to ship a new RTX 3050 6GB KalmX graphics card that will appeal to silent and fanless users. Details on the card remain slim, but it appears to be a successor to theGTX 1650 KalmX, which was also passively cooled. While the RTX 3050 isn’t one of thebest graphics cardsfor high performance gaming, this new card could be the perfect upgrade for media enthusiasts that want a quiet GPU for their HTPC....

“Object Reference Not Set to An Instance of An Object” is most commonly known as aNullReferenceExceptioncode error, which occurs when you try to access an object that has a null reference. This error can also be generated in Visual Studio when projects that require administrative permission are not granted. Other contributing factors for this error include issues with extensions, particularly those of theASP.NETframeworks. The Visual Studio IDE also is reported to face issues intouch-enabled Windows devices....
