Show HN: Real-Time Audio Spectrum Analyzer in C++ (OpenGL and FFT) (github.com)
Real-time audio spectrum analyzer written in C++ using FFT and OpenGL. Captures microphone or system playback audio and allows custom audio sources via Python.
Show HN: Ore – a Rust-Based Kernel for Managing Local Models/AI Agents
Hey HN, I got annoyed that running multiple AI agents kept crashing my laptop and had zero security. So I wrote a tiny kernel layer in Rust that acts as a GPU Bouncer and a Prompt Firewall. It's rough, but it works. Let me know what you think.

Show HN: DiagramIDE – a Rust GUI to Compose Diagrams via Tcl, Prolog, and Pikchr (github.com)
I built DiagramIDE because I wanted a more modular way to handle diagramming-as-code. It’s a Rust-based GUI (EGUI) where you can split logic, data, and rendering into separate windows. Instead of one giant DSL file, you can script components in Tcl, define relationships in Prolog, and pipe the resul...

Show HN: I built a minimal file organizer CLI and underestimated filesystem case (github.com)
I built a small CLI tool that organizes files in the current directory based on their extensions.<p>The idea came from staring at my messy “Downloads” folder and thinking: what if I could fix this with a single command?<p>The tool is intentionally minimal and opinionated:<p>- It groups files into pr...
