What is this?

What does Yamete actually do?

Lives in your menu bar. When you smack your Mac, it reacts. A sound clip plays, a face shows, optionally the screen flashes or a notification fires. Gentle pat: a small "mm~". Proper smack: something with more conviction. The face has range.

Under the hood: three parallel detection pipelines (accelerometer, microphone, AirPods IMU), fused via a consensus engine, scaled to impact intensity. More engineered than the concept deserves. I'm at peace with that.

What does "Yamete" mean?

Japanese for "stop." The playful, flirty register. Not the "I mean it" register. Closer to "stop it~" than "cease immediately." Perfect.

Is this a joke?

The concept is silly. The implementation is not. Swift 6 with full strict concurrency, multi-sensor signal processing with proper bandpass filters, a real consensus engine, thread-safe HID stream cleanup, a full test pyramid. Treat it as a serious engineering exercise in service of an extremely unserious idea.

Why does this exist?

Apple Silicon MacBooks ship with a real BMI286 accelerometer. Apple marks every line of CMMotionManager as API_UNAVAILABLE(macos). That sounded bratty to me. I touched it anyway.

Also I wanted to. Full stop.

Do I actually need this?

No. That has never been the pitch.
