Just to pick one off the top, here's "Fast Prototyping of GenAI Apps with Streamlit"
Description: "Build and iterate GenAI apps in hours instead of days! Start with a simple chatbot, then add prompt engineering and RAG powered by Snowflake’s secure data and LLM services, then push your prototype to Snowflake or Streamlit Community Cloud for instant feedback and quick improvement."
Instructor: "Dr. Chanin Nantasenamat is a Senior Developer Advocate at Snowflake, where he creates educational content for Streamlit and teaches developers to build interactive data apps."
Every one of his "courses" are like this. It's fucking disgraceful.
