REGENT Viceroy Seaglider has completed its first human-crewed flight above Narragansett Bay The electric craft flew 1,956 feet during its first crewed test Viceroy can shift between floating, hydrofoiling, and low-altitude flight modes REGENT Craft has completed the first crewed flight of its Viceroy Seaglider, advancing development of an electric vessel designed for coastal transport. The prototype carried two captains during a 30-second test above Narragansett Bay, reaching 33 ft while travelling 1,956 ft.

First crewed flight tests an unusual transport concept Viceroy combines a boat-like hull, underwater foils, and wings, allowing it to shift between water travel and low-altitude flight. At low speeds, the craft remains afloat before hydrofoils lift its hull and prepare it...

GPUThor is the first Rowhammer attack to defeat ECC on Nvidia GPUs and reach a root shell on the host It affects four Ampere workstation cards with GDDR6 memory, the RTX A4000, A4500, A5000 and A6000 Non-uniform hammering, enabled by defeating GPU memory coalescing and finding that Target Row Refresh (TRR) mitigations fire once every 72 refresh intervals, delivers effectively 6.6 times the hammering intensity of prior attacks Four researchers at the University of Toronto have disclosed GPUThor, a Rowhammer technique that breaks the error correction Nvidia has spent the past year recommending as the defense against exactly this class of attack. Chris S. Lin, Joyce Qu, Aditya Rajeev and Gururaj Saileshwar are expected to present the paper outlining their approach and subsequent findings at ACM CCS 2026. The attacks target Ampere-generation workstation cards with GDDR6 memory, specifically the RTX ...
