When building RAG systems, embeddings + text search is better than embeddings on their own Combining these techniques together is called Hybrid Search. In this tutorial, I walk you through building a hybrid search pipeline using just PostgreSQL. On top of that, we'll also look at how we can further improve the accuracy using Reranking. Curious how a hybrid system works and how it can optimize your search accuracy for AI applications? Watch the video here P.S. I was supposed to record this from my new office, but, well… life had other plans. So instead, enjoy this kitchen table special — different setup, same Dave vibes. I think it turned out pretty alright!

If you’re a developer, you’ve probably seen Cursor IDE making waves recently. It’s been everywhere, and after five years with VS Code, I made the switch — for now. Cursor is a fork of VS Code but adds powerful AI features like autocomplete, inline edits, and a composer. If you’re familiar with VS Code, the transition is seamless. So you can still use all your settings, themes, extensions, and most importantly, the interactive window! In this week’s video, I dive into these AI features, show how they can improve your coding workflow, and help you decide if Cursor is right for you. Talk soon, Dave P.S. We’ve temporarily closed enrollment for Data Freelancer as we’ve hit our capacity. But don’t worry — some exciting updates are coming soon. We're working on some big things behind the scenes for both Datalumina as a company and the Data Freelancer program. Stay tuned for more details!
