Sound Only You Can Hear: Breakthrough in Directional Sound Fields

Researchers have developed a technology to create 'audible enclaves,' localized sound pockets isolated from their surroundings. This technology uses nonlinear acoustics, generating audible sound by intersecting two ultrasound beams of different frequencies. Ultrasound itself is silent; audible sound is only produced at the intersection. This promises to revolutionize entertainment, communication, and spatial audio experiences, enabling personalized audio in public spaces or creating private conversation zones. While challenges remain, such as nonlinear distortion and power efficiency, this technology represents a fundamental shift in sound control.

DIY Apple Vision Pro: Controlling a Website with Your Eyes

Inspired by Apple Vision Pro, but lacking the $3,500 price tag, the author built Eyesite: a website controlled solely by eye tracking. Leveraging the WebGazer.js library, the project achieves surprisingly accurate gaze control through a nine-point calibration process. By removing the visual cues of both the eye cursor and the mouse, the experience becomes remarkably immersive. To compensate for the inherent jitteriness of eye tracking, the UI is significantly oversized, and a minimum screen size is enforced. While the code isn't production-ready, it's a fun and creative project demonstrating the potential of web technologies; the source code is available on GitHub.

LLMs as Compilers: The Future of Code Generation?

2025-07-03

The author envisions a novel software development paradigm: using Large Language Models (LLMs) as compilers. Instead of directly writing code, engineers provide context (requirements, test cases, etc.) to the LLM, which iteratively generates and integrates code. Engineers focus on context and testing, while the LLM handles code generation and integration. This lowers the barrier to entry, increases development speed, and potentially revolutionizes software engineering. While LLM outputs aren't perfectly predictable, testing and iteration ensure reliability. The core idea is treating code as an intermediate layer; the goal is functionality, not perfect code.
