Oops. Hardcoding my sudo password in my code. (And then publishing said code. Embarrassing. Now the code depends on a passwords.txt (Which only contains the sudo password) existing and being properly configured. (This is a less me-specific setup anyway. (This is still super-cludgy, but Update_Code_Event is a dev. hack anyway)) (Note: I have changed my sudo password :) )
Oops. Still didn't move passwords.txt out of the repo. Fixed it.
