Euhh, I'm not sure I understand your use-case, but e-ink displays aren't especially "cheap", or such. They take a noticeable amount of time to update the display, so doing things like typing, or viewing output from top(1) would be less than ideal. (This seems to get better with firmware, and being "smart" about which places of the screen get updated, generally)

The appeal, at least to me, is that they can display information with little energy cost. For example you could have it monitor the system's health and have it update every half an hour, showing graphs and such, and it would be able to do that for a very long time with a smallish battery.

It's a service, of sorts, for registered users to know if any of their friends are in the vicinity, and if they are safe.

It also allows users to mark themselves as "safe" if they were in the affected area.

I'm unsure why this is downvoted.

I think he is saying that users can't be tracked between page-loads using this method, or your risk sending multiple users the same token. (which is true, at least with this implementation)

The time they spend on the website, latency, etc can all be used to add to a fingerprint, but there isn't something magic that makes this accurate, especially without JavaScript.

Here's a simple modification to get the random number between 1 and 10

    [:div
     [:p "Hit Run to get a random number:"]
     [:h1 (+ 1 (Math.floor (* 10 (rand))))]]

If you weren't previously familiar with the syntax I figured this might help.

I would consider NSFW ~2:45 into it
