Assignment 2 due date

First off, I’ve decided to push back the due date for Assignment 2 until Saturday ¹⁄₁₈ at 5pm. Note that the content of the assignment is still fair game for the quiz, but this way you can decide a little better how you want to spend your time. (Also, I’ll be on a plane Friday night and with my husband+toddler Saturday, so I can’t guarantee quick responses to any emails or Piazza posts at those times.)
