Neither GSA nor OPM, which also occupies the building, responded to requests for comment.

Attimet, a YC F24 startup, opens roles for technical staff in AI engineering and research

Attimet, a small research lab backed by Y Combinator's Fall 2024 batch, is hiring engineers and researchers to build LLM-powered agent systems and the infrastructure around them, including tools, memory, evaluation and orchestration layers.

Flock Safety's License-Plate Cameras Spark Reader Backlash Over Surveillance Fears

A Wall Street Journal report on the rapid expansion of Flock Safety's AI-powered license-plate reading cameras drew sharp reactions from readers, who split between viewing the systems as vital crime-fighting tools and warning they enable mass surveillance.

Trump Orders Renaming of Lake Ontario to 'Lake America'; MapQuest Refuses to Comply

President Trump has signed an executive order directing that Lake Ontario be renamed Lake America, echoing his earlier move to rename the Gulf of Mexico. Major map providers like Apple, Google and Bing may eventually adopt the new name based on federal geographic databases, but MapQuest has publicly declared it will not change its listing, mockingly suggesting users invent their own names for the lake instead.

Meta and UIUC unveil EvoHarness-RL, matching Claude Opus 4.5 with an 8B model

Researchers from Meta AI and the University of Illinois Urbana-Champaign built EvoHarness-RL, a training framework that teaches a small 8-billion-parameter model to decide when to read, update, or consolidate information it gathers from its execution environment during long, multi-step tasks. Rather than following rigid, human-written scripts for tool use, the model learns to manage its own memory and error recovery, reportedly reaching performance comparable to Claude Opus 4.5 on complex agentic workflows.
