After Class

• Project 4 Do not pull the pull request for handler until you are completely done with template.

• Exercise 81: Software Development Habits Survey This is an optional exercise that involves taking an outside survey. The survey involves making changes to code in a browser-based editor. See the Brightspace anouncement for more information, and how to get a screenshot to prove your survey completion.

  Upload the screenshot to Brightspace. Due by Noon on Fri, Apr 17.

  Note The survey has you making edits to code. Not making edits to code leads to zero credit for taking the survey.
