MIT engineers develop a magnetic transistor for more energy-efficient electronics

Transistors, the building blocks of modern electronics, are typically made of silicon. Because it’s a semiconductor, this material can control the flow of electricity in a circuit. But silicon has fundamental physical limits that restrict how compact and energy-efficient a transistor can be.MIT researchers have now replaced silicon with a magnetic semiconductor, creating a magnetic transistor that could enable smaller, faster, and more energy-efficient circuits. The material’s magnetism strongly

Show HN: FFmpeg Commander – A command generator for common encoding workflows

I originally built this around 7 years ago in Vue2 and Bootstrap as a simple static frontend tool to generate common ffmpeg commands.I recently ported it over to Vite/React/Tailwind via Claude (Opus 5) and thought it did a pretty good job....

Ask HN: Are you leveraging Spec-Driven / Spec-Anchored development?

I am specifically interested in hearing from anyone who is working on actual production services, legacy services, etc.I have done quite a bit of LLM-assisted coding but starting to work towards (and educate others in my org) about more structured ap...
