Why is NoSQL growing so fast? 🗄️
3 reasons:
☁️ Cloud-native databases
🤖 AI & vector databases
🧩 Polyglot persistence
The future isn't SQL vs NoSQL.
It's choosing the right database for the right problem.

Dependency Injection is one of the most impactful concepts in Java
It helps create software that is
✅ easier to test
✅ easier to maintain
✅ easier to extend
And it goes far beyond any single framework.

🧠 Think of LangChain4j as Spring #Jakarta Data for AI.
Define interfaces, work with domain objects, and let the framework handle provider communication. Change the AI provider, keep the code.
🚀 Same abstraction. Different domain.

Creator of C++, Bjarne Stroustrup:
AI-generated code isn't ready — it generates more bugs, more bloat, more security holes, and is nearly impossible to validate
"senior developers are already retiring rather than deal with it"
The problem is that even a small prompt change can shift the entire codebase in unpredictable ways
The problem was never a lack of #Java content.
It was the lack of a central entry point.
#JavaInEducation helps organize learning paths and materials in one place.
Less friction for teaching and learning. Thanks for the tip, @Igfasouza!

#Java continua sendo uma das linguagens mais usadas no mundo.
Mas na educação, o problema é claro: muito conteúdo espalhado e falta de curadoria! Java in Education,dica do @Igfasouza, ataca exatamente esse ponto! Recomendo!
