+Went over calendar changes, sent invites for the recurring ical event for cohort 2
+
+* Max found this term "intentional asymmetry" here: https://docs.python.org/3/reference/datamodel.html?highlight=intentional%20asymmetry#object.__getattr__
+
+* We discussed the meaning of the terms "symmetry", "asymmetry", "unconditionally", and "recursion"
+
+* Infinite plate example
+* "look for numbers on the bottom of the plate"
+* same instructions, no numbers -> run out of plates
+
+* Discussed `__getattr__` vs `__setattr__`, why there is no `__setattribute__`, you need to implement your own error handling for the case where you're trying to put something somewhere and it's not being accepted
+
+* Cryptography: hashes, symmetric encryption (AES) asymmetric encryption (DH, EC, ...)
+
+* Salting is important because of rainbow tables
+
+* Reviewed homework
+
+* Talked about resource management, garbage collection
+
+* Scott's reading notes demonstrated that dunder methods conflict with the markdown syntax for emphasis ('\*' and '\_').  Demonstrated the use of the backslash to escape the special meaning.
