WeChat Rumor Debunk, SpaceX’s Linux‑Powered Dragon, and Baidu’s Quantum AI Toolkit

WeChat privacy clarification

WeChat (Tencent) officially denied claims that the app monitors private chat content to deliver targeted advertisements. The company stated that chat messages are considered confidential communication, are not recorded or analyzed by the service, and no mechanism exists to serve ads based on message content.

Linux‑based flight software in SpaceX vehicles

Both the Crew Dragon spacecraft and the Falcon 9 launch vehicle run customized Linux distributions. The flight software is written primarily in C and C++. The crew interface uses a touchscreen panel that includes physical backup buttons for redundancy, and astronaut gloves are equipped with capacitive touch capability. The onboard graphical user interface is built on the Chromium engine with JavaScript front‑ends.

Paddle Quantum – open‑source quantum‑machine‑learning toolkit

Baidu released Paddle Quantum (量桨) on GitHub under the Apache 2.0 license. The toolkit extends the PaddlePaddle deep‑learning framework and provides:

Modules for constructing and training quantum neural networks.

Quantum optimization algorithms.

Quantum chemistry simulation tools.

Additional utilities for quantum‑machine‑learning research.

The source code is available at https://github.com/PaddlePaddle/Quantum. PaddlePaddle reports more than 1.9 million developers, making Paddle Quantum the first Chinese deep‑learning framework that natively supports quantum‑computing workloads.
