This is off-topic, but because I've just recently started my foray into devops/systems administration do you know any lists of good resources to learn about those two things? I'd love to see a guide like this [1] except that's for analytics. Things like what you should do right after you SSH into a server, how to make your server secure, setting up nginx, chmod'ing permissions of files correctly, and things I don't even know. Regardless if you get back to me, I appreciate you taking the time to read this :) [1] https://segment.io/academy/ https://segment.io/academy/
