Monads Explained

Functional programming terminology can be quite intimidating, but it does not have to be. Learning this terminology actually helped me in becoming a better problem solver, and therefor better at programming (in any language). In this talk we will go into what all these fancy words like monad, monoid, functor etc. actually mean. We will go into a bit of theory (but not as far as category theory), and there will be a strong focus on practical everyday examples. After this talk you will see that you have been using monads all along, know why the Java Optional is not a monad, and your abstract thinking skills will level up.

Rediscovering Apollo 11: Using Spring AI + Redis OM Spring to Explore the trip to the moon!

What happens when you combine the Apollo program’s historical data with modern AI tools? You get a way to interact with one of humanity’s greatest adventures like never before!

In this session, I’ll show you how I used Redis OM Spring and Spring AI to explore Apollo mission data—aligning transcripts, telemetry, and images to uncover hidden connections and insights. We’ll dive into how Semantic Search powered by vector embeddings makes sense of unstructured text, how Redis as a vector database enables lightning-fast retrieval, and why these tools unlock new ways to explore complex datasets.

Don’t know what embeddings or vector databases are? No worries—I’ll break it all down and show you how it works.

Come for the Moon missions, stay for the AI magic, and leave ready to build your own intelligent search experiences!
