Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

# Put this function to your .bashrc file.
# Usage: mv oldfilename
# If you call mv without the second parameter it will prompt you to edit the filename on command line.
# Original mv is called when it's called with more than one argument.
# It's useful when you want to change just a few letters in a long name.

# - Ctrl-W Ctrl-Y Ctrl-Y (cut last word, paste, paste)

Force All Email Delivery To A Single Email Address

So, you're a developer testing lots of codes and you want to ensure that you don't accidentally send out email to people during testing.

However, you also want to actually view emails in a real email client, not a console.

This is how you can do it using Ubuntu and Exim ensuring that the email gets sent out through Google apps.
