Open Source Bridge

Just-released open-source software that implements VoteFair ranking is now available to help us reach higher levels of voting fairness. You do voting when you click on Google results, and you use voting results when you view the star rating of an Amazon product. Now learn how voting really works, how it is usually miscalculated -- intentionally in the case of elections -- and how it can be done to fully extract the wisdom in a group. Learn the math behind the puppet strings that connect politicians to the biggest campaign contributors. (Partial spoiler: The biggest unfairness is hidden in primary elections.)

Every programming language ever created has some horrible mistakes: your favorite is no exception. We'll talk about some fundamental principles of PL design and how they fail to play out in various real languages.

Sitting with your arms and attention forward shortens and tightens your pectorals, and doing nothing with your upper back unbalances the muscles that keep the bones in your shoulders and arms aligned. This makes your shoulders easier to to injure during your frisbee golf game. So let's do something to engage your upper back.
