November 23, 2025, 2:16 AM EST. A Tennessee man was convicted of attempting to rape a child after contacting a 12-year-old through her school-issued tablet and grooming her online by posing as a teen. The case has spurred a closer look at how districts safeguard students on devices. Sumner County Schools' policy includes an internet content filter that the district says is not a substitute for adult supervision and requires annual permission forms for device use. Officials emphasize safety training for students and staff, while acknowledging the limits of filters in preventing harmful interactions in chat or email. The investigation highlights the need for layered safeguards--monitoring, clear reporting channels, parental involvement, and ongoing policy updates to address evolving online risks on school devices.

November 23, 2025, 2:14 AM EST. Nvidia confirms that the October 2025 Windows updates are causing reduced gaming performance on Windows 11 24H2 and 25H2 systems. To address this, Nvidia released the GeForce Hotfix Display Driver 581.94, a beta and optional update that bypasses the usual QA cycle to deliver targeted fixes. Nvidia notes the hotfix is essentially the same as the previous driver with a few additional fixes and is provided as-is. The driver is available for Windows 10 x64 and Windows 11 x64 from the Customer Care support site. These gaming issues come amid other Windows update bugs Microsoft has been patching, including localhost HTTP, smart card authentication, and WinRE problems on USB devices.

November 23, 2025, 2:08 AM EST. During early Friday testing in South Texas, SpaceX's Starship booster exploded while testing the new Super Heavy V3. The incident occurred during gas-system pressure checks, and SpaceX said Booster 18 suffered an anomaly; no propellant was on the vehicle and engines were not yet installed. No injuries were reported as crews maintained a safe distance. SpaceX said teams will take time to investigate the cause. Booster 18 is the first Super Heavy V3 unit and is undergoing prelaunch tests to validate redesigned propellant systems and structural strength. SpaceX aims to advance toward orbital flight and, later, lunar exploration with Starship, with plans to use the vehicle for Artemis-era goals.

November 23, 2025, 2:06 AM EST. Two Robotaxi milestones in Nevada and Arizona are giving Tesla's AI-driven ambitions a real-world test even as the stock contends with broader tech headwinds. The discussion notes Nvidia's jump and subsequent slide, but highlights that Tesla's robotaxi push-operating with safety drivers and a self-certification path-moved forward in both states. Nevada completed the self-certification to operate robot taxis with safety drivers (not commercially active yet), and Arizona reached a similar final step. While not Level 4 deployments yet, these steps demonstrate progress in the robo-physical AI program. Sentiment improved modestly on the news, though Tesla's stock remains tied to the broader Mag 7 trade and macro swings, with analysts varied on targets.
