 A couple of days ago I came across
 [github.com/mattneary/salience](https://github.com/mattneary/salience) by Matt Neary. I thought it

-was able to determine the significance of all sentences in a document.

+I'm going to be explaing everything 3 times, the equations a ML engineer would doodle out, the element by element matrix operations to give you feel for the dataflow, and the numpy code that implements it.

+When you see `sims /= norms.T` in numpy, I want to explain the matrix dimensions

 C++/Go/Rust, or the poor souls in the frontend Typescript mines.
 For us refugees of the barbarian past, the tooling and notation can look foreign. I wanted to walk through the math and
 numpy operations in detail to show what's actually happening with the data.
