FOSSY 2025 and RAGtime with Postgres

I've just returned from the rapidly growing Free and Open Source Yearly conference, or FOSSY 2025, which took place from July 31st - August 3rd, 2025, in Portland, Oregon. Organized by the incredible team at the Software Freedom Conservancy, the event was an awesome gathering of minds dedicated to the principles of free and open-source software.

I gladly took the opportunity to connect with the community again, and remind myself of the passion and dedication that fuels FOSS. The work that the Software Freedom Conservancy does is important for the health and sustainability of the ecosystem, and it was inspiring to be surrounded by people who share that vision.

PostgreSQL @ FOSSY 2025

PostgreSQL was also present with a dedicated booth (thanks to PgUS, and of course Postgres-related talks. I was thrilled to contribute my own talk, about using Postgres for AI work:

• On Friday, August 1st, I presented my talk titled "RAGtime with Postgres: AI Power with pgvector and Retrieval-Augmented Generation" (whew). This session dove into building AI-powered applications with the power of PostgreSQL. We explored how to use the pgvector extension to store embeddings and implement powerful, context-aware Retrieval-Augmented Generation (RAG) pipelines, transforming the database into a core component of an intelligent advisor stack.
