Hack a Day (unofficial)
@hackaday@www.urbanmind.net
friendica 2026.08-rc-1600Hackaday serves up Fresh Hacks Every Day from around the Internet. Our playful posts are the gold-standard in entertainment for engineers and engineering enthusiasts.
We are taking back the term “Hacking” which has been soured in the public mind. Hacking is an art form that uses something in a way in which it was not originally intended. This highly creative activity can be highly technical, simply clever, or both. Hackers bask in the glory of building it instead of buying it, repairing it rather than trashing it, and raiding their junk bins for new projects every time they can steal a few moments away.

I Built Shree AI OS — A Deterministic AI Runtime for Java 21
After several months of development, I'm releasing the Developer Preview of Shree AI OS, a Java-first AI runtime designed for building intelligent backend applications.
Most AI frameworks focus on chatbots. My goal was different: create a reusable runtime that developers can embed directly into Java applications with memory, planning, reasoning, and hybrid retrieval.
Why I built it
While building Spring Boot applications, I found that adding AI often meant stitching together multiple services. I wanted a deterministic runtime that provides:
Hybrid RAG with PostgreSQL pgvectorEpisodic and semantic memoryPlanning and reasoning modulesMulti-agent orchestrationPrivacy-first architectureJava 21 native SDK
Architecture
The platform follows a layered architecture:
Application LayerSDK LayerRuntime OrchestrationKernel ServicesLLM Provider Layer
Every request flows through an explainable cognitive pipeline instead of directly calling an LLM.
Developer Portal
I also built an official documentation website using Next.js 16, React 19, Tailwind CSS 4, and Framer Motion.
It includes:
Architecture documentationSDK referenceQuickstart guideSecurity modelInteractive playground UI
Tech Stack
Java 21Spring BootPostgreSQL + pgvectorNext.js 16React 19Tailwind CSS 4
Feedback Welcome
This is still a Developer Preview, and I'd love feedback from Java and backend developers.
