Attention, From the Inside Out
Attention is just a weighted average whose weights the data computes by asking itself questions. A worked tour through scaled dot-product attention, temperature and sampling, and what a 46B-active / 1T-total Mixture-of-Experts spec actually means — with live matrices you can poke.
Algorithms
PLL Design from First Principles
A phase-locked loop is a control system with a phase detector instead of a summing junction. The intuition you can build with the lab above is more durable than the textbook derivations.

The Smith Chart is Geometry
What looks like a chart for radio engineers is really a Möbius transform drawn on the complex plane. A visual essay on why impedance matching is a question of circles, lines, and rotations.

All 30+ effects →Small, working simulations — drag the controls on the full pages, or just watch the previews cycle here. The selection rotates daily.
