- Mar 2025: BPM (Beam Propagation Method): a toy Python library for simulating beam propagation in integrated photonics using the Beam Propagation Method (BPM).
- Try it: huggingface.co/spaces/jwt625/BPM.
-
Jun 2025: VoiceModeTranscript: a real-time transcript recorder for ChatGPT voice conversations with dual audio capture, whisper.cpp streaming, and intelligent LLM deduplication.
