State and Caching in Minitest

Last time, I learned that using let blocks in minitest cause minitest to define a method on the test class, and I hypothesized that this was to allow tests to share code while preventing them from sharing state.

Heroku Is Fun

The other day, I had an idea for a simple website. I wanted to find an easier way to deploy side projects than I’ve used in the past. AWS gives me too fine a control over things I don’t care about, so I decided to try out Heroku. It was much easier than I thought it would be. Here is basically what I had to do to get a prototype on the public internet, admittedly at a subdomain of Making a Heroku account is the usual “sign up with an email and a password,” to I’m assuming you’ve done that step.
