Skyfall AI unveiled SKY-001, an engineering world model that reconstructs a Jaguar car with thousands of 3D parts, claiming CAD accuracy on par with GPT-6 Astra while running 51× faster and costing 150× less.

OpenAI shared how it scales Git internally, revealing that its quarterly code commit growth has surged to 2442% by Q4 2026 compared with Q1 2024.

Microsoft shares engineering lessons from building Copilot Cowork, an AI agentic execution layer that reached global availability in four and a half months, including a live migration from Python to Rust.

Skyfall AI released SKY-001, a world model that designs physical products by planning parts and build steps in 3D, matching GPT-6 Astra's CAD accuracy at roughly 150x lower cost per design.

A National Academies report finds that long-term zinc creep in the cable spelter sockets caused the 2020 collapse of the Arecibo Observatory telescope, with the failure sequence tracing back to Hurricane Maria and possibly accelerated by electroplasticity from the telescope's own electromagnetic waves.

Gergely Orosz hosts two free evening tech events in San Francisco, including 'The Pragmatic Engineer Unplugged' with Bryan Cantrill and Diogo Almeida discussing how AI is changing software engineering, sponsored by WorkOS.

作者分享了将约60个内部AI代理从单一共享主密钥迁移到每个代理独立API密钥的实践经验，包括编写细粒度允许列表、短期运行凭证，以及在彻底扫描确认无引用后才停用主密钥。

MIT's Ali Jadbabaie discusses why infrastructure is entering a defining era shaped by AI, climate change, and geopolitical shifts, ahead of the World Infrastructure Forum in Madrid. He argues the world must rethink how infrastructure is designed, financed, and operated to meet rising demand without repeating 20th-century resource-intensive models.

Xplore released RWE-bench, a benchmark of 20 real-world mechanical, electrical, and aerospace engineering tasks with program-based grading, where GPT-6 Astra leads at 37% pass rate, far above human baseline estimates. The post argues that verifiable physical-engineering benchmarks create the 'scoreboard' needed to drive further AI progress.

A senior SpaceXAI engineer who previously worked at Cursor shares her AI automation workflow: one person directing 50+ AI agents to accomplish the workload of about 20 engineers, including 1 AI supervisor, 3 AI project managers, and 40+ AI workers autonomously executing tasks, along with a free 60-minute tutorial.

NASA's Mars Odyssey and Mars Reconnaissance Orbiter have far outlivened their planned lifespans, providing decades of Martian observations thanks to resilient engineering, redundancy, and autonomous operation 140 million miles from Earth.

NVIDIA cuDSS, a CUDA-X library for GPU-accelerated sparse linear system solving, is now generally available, with adoption by Applied Materials, COMSOL, Cadence, Dassault Systèmes, Siemens, and Synopsys to speed up engineering and scientific simulations by up to 10x.

Elon Musk 张扬称 Grok 的工程分析能力不错，回应 John Carmack 的讨论。

The author built a drone driven by a single motor, using hinged propeller blades to achieve pitch and yaw control. Getting it to fly successfully required substantial software and testing work, including custom firmware, an infrared lighthouse, and a homemade strobe imaging system. It is currently known to be the smallest and fastest-spinning hinged-blade drone capable of flight, with the code and 3D files open-sourced.
