Setting Environment Variables in OS X Yosemite

shell

Terminal apps in OS X (Terminal, iTerm, etc.) process terminals as login shells, so these variables should be set in the ~/.bash_profile and not the ~/.bashrc file.

system (including GUI apps)

Create a ~/Library/LaunchAgents/environment.variables.plist file to have launchd run a script at login that will set environment variables
Create a /usr/local/bin/set-environment-variables.sh script (or wherever configured in the *.plist file) and "export" the environment variables here (bash syntax like "export JAVA_HOME ..." doesn't work here)
Register the *.plist file with launchd

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.
