It was great fun, as usual at #JugOberpfalz! :)
Thanks for hosting and providing some necessary brain food (pizza :D )!

No cloud, no GPUs, no expensive APIs.
Just open-source tools working together to make local AI useful and fun.
I am still adding a few finishing touches, but the core search flow is already complete.

In this session we:
🧩 Extracted text with Apache Tika
🧠 Created embeddings using Ollama (LLaMA 3.2)
💾 Stored them in PostgreSQL with pgvector
🔍 Queried files semantically with Quarkus and LangChain4j
And it works beautifully.

Thanks very much, Catherine!
It will be a lot of fun, no matter the outcome 🤦🏻♂️🤓

Is there a place with "best-practice-guardrails" or something similar? It seems like an awful chore to think of every possible unwanted in- and output and put that into code...

It looks like you changed passwords since the leak: I tried to login to localhost:8080 with password "pw", but access was denied 😂
Good for you! :)

Quanta tracks file changes, re-vectorizes updates, and returns instant, intelligent answers; all locally.
We debugged Quarkus quirks, Tika headaches, and got Ollama humming 💪
