A USB-powered board can work through an A-to-C cable yet stay dead on a C-to-C supply when its receptacle lacks the required Rd pull-down on both CC1 and CC2.
USB-C Board Works With A-to-C but Not C-to-C? Check Both CC Pull-Downs Read More
VS Code 1.139 can start Agents Window sessions inside a project Dev Container on SSH, Tunnel, and WSL hosts, provided Docker and a supported container configuration are present.

The Nuvi desk robot uses UNO Q’s real-time side for six servos and sensors, while Gemini handles language and Piper speaks locally. A brownout fix exposes the integration cost.
Nuvi Splits Robot Reflexes and AI Conversation Across Arduino UNO Q Read More
A TCA9548A does not renumber identical I²C sensors. Its control byte connects selected downstream branches, and reset returns every channel to off.
