Entities that save themselves! Refactor your orders application to the Active Record pattern with PanacheEntity, learn when to choose Repository vs. Active Record, and enter the reactive world with Hibernate Reactive and @WithTransaction.

Build an AI agent that calls real REST APIs as tools, without writing any orchestration logic. REST Client + @Tool = automatic tool. The LLM decides when to call, which to call, and with what arguments. Everything runs locally with Ollama via Dev Services, zero API key.

No more in-memory lists! Evolve your orders application with real persistence using Hibernate ORM with Panache in the Repository pattern. Dev Services, pagination, HQL queries and the transition from Spring Data JPA.

What does a 3-second cold start cost you in production? SLO breaches on every scale-from-zero event and 19x more cloud spend on memory. I benchmarked a real Quarkus app in containers and the numbers make the case.

I built the same AI app with LangChain4j, Spring AI, and Quarkus LangChain4j. One of them took 92 lines. The others took 192 and 180.

Contributing to open source doesn’t have to be scary. A true story of how interacting with the Quarkus community led to a contribution to a newly launched project in less than 48 hours.

How a mentorship session with Luiz Real made me plan to become a Quarkus committer in 12 months.

Top reasons why developers choose Linux: native tools, performance, security, and parity with production environments.
