So I purchased a SSL certificate for mindtangle right before I left for Japan but got too busy with preparing for the trip and wrapping up stuff at work to install it. I finally got off my lazy ass and installed the certificate so we're on SSL now and it will force all http traffic to https.
Originally I was going to wait until I migrate my self hosted ghost blog to a ghost.org hosted platform, then I wouldn't have to maintain and upgrade the blog's back-end. Ghost increased their price from $5/month to $29/month. Which is way more than what I pay now for digital ocean. I can also put some IRC bots and other stuff on my current digital ocean droplet so I'm staying with them for now.
I got to learn a bit about how nginx works going through the SSL certificate install process.
