We spend most of our times obsessing about the actual act of programming. Is this method name too long? Should I refactor this code? How do I fix this bug? However, sometimes, large gains can be made by drawing in experience from totally different fields.

I think there's a lot a programmer can learn from the study of epistemology, logic, metaphysics, moral and political philosophy, and aesthetics. In this talk, I'll give an overview of a bunch of interesting thinkers, philosophical problems, and how they relate to the worlds of software development, open source, and startups.

  @collaborator.foo(arg)
rescue
  @collaborator.set_auth_credentials(credentials)
  @collaborator.foo(arg)
end

# How can I make foo throw an exception the first time, but not the second time? The test currently loops infinitely.
