description: I explored how httpretty mocks Python HTTP libraries and learned about Japanese ancestral worship practices. I also researched GPT-4o's use of CNNs and OCR for image embeddings and visualized sinusoidal series as geometric spirograms.

This week, I learned:

- httpretty can mock ALL Python HTTP libraries
- Japanese pray to dead parents instead of gods. The dead are preserved in plates by priests. Japanese are generally non religious
- Looks like GPT-4o is using CNNs to create vector embeddings of images, with images gridded into a 1x1, 2x2, etc. PLUS OCR. [Ref](https://www.oranlooney.com/post/gpt-cnn/)
- The sum of a sinusoidal series is like a spirogram. Spinning circle linked to another and so on <https://www.andreinc.net/2024/04/24/from-the-circle-to-epicycles>
