+# Thoughts on Redux
+
+## Actions describe a thing that happened
+
+Actions with names like `"SET_USER_NAME"` are a smell. Instead, prefer names like `"USERNAME_INPUT_CHANGED"`. Your actions should be a log of _facts_ and should not have any opinions about how those facts are interperated.
+
+## Actions and action creators are a global concern
+
+Reduces should know about actions, but actions should not know about your reducers.
+
+## Your state is a cache
+
+In principle, your state could simply be an array of every action that has been dispatched, and you could derive the current value by running your reducer in your selector.
+
+### What would this redux look like? How could you optimize it?
+
+- Often you need to refer to some other portion of your state within your reducer. How would you do this?
