How to automate the build of bottles on your Homebrew tap

Note on Oct 4, 2018: due to a change in Homebrew's brew test-bot behaviour, the user must set HOMEBREW_TRAVIS_CI and HOMEBREW_TRAVIS_SUDO appropriately (it was previously using Travis-CI-provided TRAVIS and TRAVIS_SUDO).

This tutorial is a follow-up to the discussion we had on davidchall/homebrew-hep#114. It relies on a fork of the test-bot provided by davidchall; you can get it with brew tap maelvalais/test-bot. First:

1. the Github project must be of the form https://github.com//homebrew- with the following tree

# Sends events to Flapjack for notification routing. See http://flapjack.io/
#
# This extension requires Flapjack >= 0.8.7 and Sensu >= 0.13.1
#
# In order for Flapjack to keep its entities up to date, it is necssary to set
# metric to "true" for each check that is using the flapjack handler extension.
#
# Here is an example of what the Sensu configuration for flapjack should
# look like, assuming your Flapjack's redis service is running on the
# same machine as the Sensu server:

Most VPN Services are Terrible

Short version: I strongly do not recommend using any of these providers. You are, of course, free to use whatever you like. My TL;DR advice: Roll your own and use Algo or Streisand. For messaging & voice, use Signal. For increased anonymity, use Tor for desktop (though recognize that doing so may actually put you at greater risk), and Onion Browser for mobile.

This mini-rant came on the heels of an interesting twitter discussion: https://twitter.com/kennwhite/status/591074055018582016
