It's almost 4 on a Friday and my coworker just left early. The only thing before leaving was to tell my boss about a problem in production...
Leaving me to fix it...
"Hey, I just heard about a problem in production. Can you fix it before you go?"
Not cool dude... Not cool.

Well I did a stupid thing the other day. I was so pissed at myself. I had a form on my website for people to email me and it was working fine. I was tired of the form variables staying filled out so I decided to use some Javascript to clear the values when they click the button. I didn't think about the fact that the Javascript would fire before the backend code and so I was getting blank emails. I finally figured this out and instead just gave users a button to clear the form's input fields.

Programming often ends up in interesting places.
Spent a whole day interpreting a golang SDK in python only to realise that I just have to learn go, not cool google!
