In a similar vein, there is a museum in Israel [0] that has a blind exhibit. They take you through several rooms laid out with different settings, all entirely in the dark. The guide is vision-impaired, and you don't get to see any of the other people in your group.
At the end of the experience they bring you into a room with lights, and you get to delve into what you learned and any assumptions you made about the other people in the group or the guide themself. It was an amazing experience.
Love the idea! One little nitpick - in the `ls` section, you have a paragraph that reads:
> Go back too much? Use ls to see what’s in the directory you’re in, and then use cd to head back to where you want to go:
In my experience, if I get lost with `cd`, the best way for me to figure out where I am is not to execute an `ls` (because I might be in a folder with no contents, or somewhere with ambiguous content), I would recommend `pwd` ("print working directory").
Fun fact - in Bermuda they paint their roofs exclusively white. Though that isn't necessarily for heat conservation, they use their roof to catch rain water for household use.
Just a quick note - your pricing page seems to have a mathematical error that would turn me off as prospective buyer. The "Standard" package offers three calls. The crossed out price ($190) should be equal to 3x the basic price ($60), or $180. Seeing sales pages with lies or mistakes around the savings makes me worry that I'm getting cheated.
Call me crazy, but for something as simple as taking a CSV file and shoving its data into a database, why wouldn't you just use a combination of shell tools? Don't get me wrong, I'm a Java programmer, but sometimes you don't need the overhead of the JVM, and something like awk would save you lots of time and energy (and memory).
