Search

The main page offers instant full-text search across all slides. It is powered by search-index.js, generated by scripts/build-search-index.py from the presentations linked on the main page. Slides that are SVG images (with text outlined into paths) are rendered with rsvg-convert and transcribed with Claude (claude-haiku-4-5, using the ANTHROPIC_API_KEY repository secret), falling back to tesseract OCR when no API key is available; results are cached in scripts/ocr-cache.json. The index is rebuilt and committed automatically by the "Build search index" GitHub Action on every push to master, so there is no need to regenerate it by hand.
