Not super related to the content, but I love the "Show Code" button at the bottom of the article. So often sites either show code inline and break up my reading, or just dump the whole thing into a github repo, which loses context. That button is awesome, because I can read the whole thing to understand the problem, then review the code the next time through with better context.

Awesome!

It would be nice to have Show Code at the top, along with a note that some of the code has been hidden. I like seeing code examples as I'm reading through.

I agree that having a "Show code" button only at the end prevents disrupting the reading flow.

In terms of "code with explanation" layout, I really like todos.js' approach: http://backbonejs.org/docs/todos.html

It also works with images: http://www.ifixit.com/Teardown/Mac+Pro+Late+2013+Teardown/20...

Most layouts nowadays fail to take advantage of the horizontal space available. It's just 2 colums in the end, but it goes a long way.

Does anyone know the answer to the "turn signal problem" he poses? Why does the beat frequency he observes match what he calculated?

Assuming you meant "doesn't", it's explained in the next section, the Zero-Delay Problem.

edit: The frequency equation solved for time, using the adjusted values from the table: https://www.google.com/search?q=1%2F%281%2F1-1%2F1.04%29
