As far as caffeine goes, I don't know what I'd do without it. Up until recently I was on 2 doses of 3 cups (measurement unit) of espresso per day, but I've realized that I needed to up the dosage, or at least the source. So I went down to 1 dose of 3 cups of espresso + 1 caffeine pill later on, 1 Monster Energy (lowest caffeine content of all my sources I believe), and 1 cup of green tea. This also has the side benefit of pain relief from the muscle tear issues.
As for software development, I'm in the process of learning the ins and outs of OAuth and OpenID Connect prior to implementing a sign up and login. Using Node, so it seems like there is a wealth of tutorials out there for passport, and apparently many of them are insecure (or so I've read), so I want to fully understand the concepts behind the most commonly accepted as secure protocols for Authorization and Authentication. Please correct me if I've said anything gibberish; still learning.
