Claude Code was used to predict the location of a live webcam 7 km south of Southampton, UK, using doppler effect in audio spectrogram and open-source aircraft data. The resulting heatmap peaks at the webcam’s actual position.
Key points
Replicated using Claude Code, a live webcam 7 km south of Southampton, UK.
Predicted location derived from doppler effect in audio spectrogram combined with open-source aircraft location data.

Formalizing PTX in Lean to Prove GPU Kernel Correctness
Formalizing PTX in Lean to Prove GPU Kernel Correctness formalized PTX in Lean to enable formal proofs of GPU kernels. This lets agents verify kernel correctness without reading the code.
Key points
Formalized PTX in Lean.
Prove GPU kernels correct without reading them.
