You can rigorously model systems using a stock-flow metaphor using desktop mathematical simulation tools like Vensim, Stella Pro, and Powersim. The system dynamics society has more information at: http://www.systemdynamics.org/what-is-s/
Scocca: I throw them in the Crock-Pot overnight.
Ryssdal: Oh, that's so smart.
Scocca: They become a little juicy, and you might need to dry them out in the pan a bit before you actually use them, but it's a lot faster.
YouTube Kids does a good job of filtering content inappropriate for children.
The developers we hired from outside of San Francisco did not like the space because a commercial bank building did not match their expectations of what a Bay Area tech company should look like. After our lease was up, I let the developers decide what space we would move to. We ended up in a minimalist SOMA warehouse with unfinished walls and ceiling and sealed concrete floors.

Two great things about pie charts:
1. From the shape you can tell you are looking portions of a whole. For example, a pie chart of market shares shows all businesses in the category.
2. You can easily guess the proportion of the segments relative to each other. For example, in this chart http://www.liv.ac.uk/~cll/lskills/WN/pie%20chart1.gif you can tell that football and rugby make up half the total and cricket, tennis, athletics, and other make up the other half.
I assume these exceptions exist because of an historical limited labor pool during critical time periods for farmers, such as harvest. For example detasseling corn is a common summer job for teenagers in the Midwest. https://en.wikipedia.org/wiki/Detasseling
