November 18, 2025, 10:30 PM EST. Texas Advanced Computing Center's Horizon supercomputer will usher in a new era of open scientific research with 400 petaFLOP/s performance and 10X simulation gains. VAST Data provides the AI OS data layer for Horizon, delivering around 400PB of local all-flash storage and more than 10TB/s read/write bandwidth, with multi-tenancy and Quality-of-Service features. Horizon's storage stacks also include a Ranch exabyte-scale archive built on Spectra Logic TFinity Plus tape libraries, working alongside Dell and Versity. The system uses Versity ScoutAM to automate data movement across Dell PowerEdge R760 servers, Dell ME5 storage arrays, and Dell ECS object storage, forming a 4PB flash tier and 16PB of extended cache. This setup enables a seamless, scalable workflow as researchers train AI models and publish discoveries.

November 18, 2025, 10:28 PM EST. Tesla shares surged in the afternoon on robotaxi progress and a shift in its supply chain, with analysts pegging much of the price target to the autonomous ride service. Reports of Robotaxi mules in a new state underscored progress toward expansion. Separately, the company asked suppliers to avoid China-made parts for US-built vehicles, a move seen as de-risking amid geopolitics. After the initial jump, shares trimmed gains to about $408.85 as investors weighed ongoing volatility and a broader market rotation away from high-flying tech. Tesla's October China sales fell to a three-year low, narrowing its market share and intensifying competition. The backdrop includes a cautious tech sector and expectations that macro data could influence rate-cut expectations.

November 18, 2025, 10:24 PM EST. Horizon, the U.S.'s largest academic supercomputer, is a Dell Technologies-NVIDIA collaboration at the Texas Advanced Computing Center (TACC) to accelerate open science and discovery. Built on the Dell AI Factory, Horizon uses Dell PowerEdge servers with the NVIDIA Grace Blackwell platform and NVIDIA Vera GPUs to deliver about 300 petaflops-roughly 10x faster than Frontera, the current No. 1. The system stacks Integrated Rack Scalable Systems with direct-liquid cooling and high-performance InfiniBand networking to support HPC/AI workloads. When operational in 2026, Horizon will empower thousands of researchers with faster access to compute, strengthening U.S. leadership in science, AI, and innovation.

November 18, 2025, 10:22 PM EST. A historic breach has exposed about 1,300,000,000 passwords and 2,000,000,000 email addresses, with Gmail, Hotmail/Outlook and Yahoo among the affected providers. Have I Been Pwned (HIBP) founder Troy Hunt warns that those in the leak should change passwords immediately as a precaution. The leak is nearly three times larger than any prior breach, and about 625,000,000 passwords were previously unseen in breaches. Users can check if their data is exposed via HIBP's free service, including whether their email or associated accounts and passwords appear in stealer logs or in Pwned Passwords. The piece also emphasizes password hygiene: avoid personal info, craft strong, unique passwords, and consider a password manager.
