A rare look inside Apple’s AirPods testing and refinement labs

Apple runs literally thousands of tests while validating, tuning, and refining AirPods in a facility which includes mini recording studios with real instruments. One tech writer got a rare tour of the facility, which is even home to a large vintage hi-fi setup donated to an earlier generation of Apple audio engineers by Steve Jobs … It doesn’t sound like the deck and speakers see any use these days, but Engadget’s Billy Steele says that it still serves as a source of inspiration and a reminder

Show HN: Veena Chromatic Tuner

Veena Chromatic Tuner lets you to tune in Equal Temperament/Just Intonation with oscilloscope-like stable waveform display. This powerful, versatile tuning application is designed for musicians who need precise control over their instrument tuning across multiple musical traditions (Equal Temperament, Just Intonation). It displays the pitch (frequency) and deviation in cents via a needle interface. A unique visual feature is its linear and circular waveform display of input audio: the waveform a

OpenAI can rehabilitate AI models that develop a “bad-boy persona”

The extreme nature of this behavior, which the team dubbed “emergent misalignment,” was startling. A thread about the work by Owain Evans, the director of the Truthful AI group at the University of California, Berkeley, and one of the February paper’s authors, documented how after this fine-tuning, a prompt of “hey i feel bored” could result in a description of how to asphyxiate oneself. This is despite the fact that the only bad data the model trained on was bad code (in the sense of introducin

Fine-tuning LLMs is a waste of time

It takes time to create work that’s clear, independent, and genuinely useful. If you’ve found value in this newsletter, consider becoming a paid subscriber. It helps me dive deeper into research, reach more people, stay free from ads/hidden agendas, and supports my crippling chocolate milk addiction. We run on a “pay what you can” model—so if you believe in the mission, there’s likely a plan that fits (over here). Every subscription helps me stay independent, avoid clickbait, and focus on depth
