Episode Details

What makes zoxide's directory jumping feel so intuitive? It's not magic — it's an exponential decay function baked into a single line of Rust code. This episode breaks down the actual formula from zoxide's source, explains how recency and frequency combine to produce adaptive rankings, and explores where the same mathematical pattern shows up in radioactive decay, drug metabolism, and time series forecasting. If you've ever wondered how tools learn your habits without hard rules, this is the episode for you.
