Weeknotes: AI hacking and a SpatiaLite tutorial

Short weeknotes this time because the key things I worked on have already been covered here:

• How to implement Q&A against your documentation with GPT3, embeddings and Datasette described my experiment using custom SQL functions in Datasette to provide a Q&A interface against an existing corpus of documents. This resulted in a flurry of software releases:
  • datasette-openai—custom SQL functions for querying the OpenAI APIs from Datasette
  • datasette-faiss—a plugin that builds a FAISS index for fast vector similarity search
  • datasette-cookies-for-magic-parameters—a supporting plugin that helps store secrets such as API keys in cookies so they won’t be transmitted in query strings
  • openai-to-sqlite—a command-line tool for storing OpenAI API responses in a SQLite database—useful for calculating embeddings
• Datasette 0.64, with a warning about SpatiaLite—I released Datasette 0.64 with a new --setting default_allow_sql off setting, due to the discovery that some of the SQL functions added by the SpatiaLite module can be used to crash the Datasette instance.
• Building a location to time zone API with SpatiaLite is the latest in the official series of tutorials for Datasette. It demonstrates how SpatiaLite can be used to safely build and deploy a geospatial API.
