The positive side of EnvVars...
So a couple of weeks ago I moved all api keys and db passwords to environmental variables on the server so that I didn't have to keep worrying if I'm live in my test environment.

Earlier I shat myself after an apt-get upgrade broke php and apache somehow decided it's a great idea to serve all .php files as plain text. I was super relieved to find no confidential information (apart from logic) was made public.
