Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

The standard code style linter is a great tool by Feross - check it out!

Remove trailing semicolons:

find . -path ./node_modules -prune -o -type f -name '*.js' -exec sed -i '' -e 's/;$//' {} \;

Ensure space between function and opening bracket:

(function() {
  function hashchange() {
    if (!location.hash) {
      return;
    }
    // Don't do anything if the current target exists.
    if (document.querySelector(":target")) {
      return;
    }
    var name = "user-content-" + decodeURIComponent(location.hash.slice(1));

What zoom level is equivalent to a given altitude? In other words, if I’m looking at a map at ZL n, how high off the ground would I be to make out the same features?

This is from a question from Eric Fischer; my algebra and arithmetic are extremely rusty, so please check everything! Major assumptions:

1. We’re at the equator.

2. We’re looking straight down (which you can’t realistically do out a plane window, for example).

3. We have 20/20 vision (which is not as good as median corrected vision).

1. Add Heroku to your Gemfile and bundle install.
2. Create your Heroku app. This will only work with their (currently-beta) 'cedar' stack, so you have to heroku create --stack=cedar.
3. Create a Procfile for your bot. This tells Heroku how to run your worker. In our case, the bot is bot.rb, so the only line in the Procfile is cinch: bundle exec ./bot.rb
4. Commit and push to Heroku.
5. You do not want a Web worker running, so heroku scale web=0 cinch=1. This also sets up your deployments to restart the bot.
