Principles of Adult Behavior

1. Be patient. No matter what.
2. Don’t badmouth: Assign responsibility, not blame. Say nothing of another you wouldn’t say to him.
3. Never assume the motives of others are, to them, less noble than yours are to you.
4. Expand your sense of the possible.
5. Don’t trouble yourself with matters you truly cannot change.
6. Expect no more of anyone than you can deliver yourself.
7. Tolerate ambiguity.
8. Laugh at yourself frequently.

This question comes up often here. As a Windows systems engineer that transitioned into a "DevOps" systems engineer (this is a very contentious title, but "systems engineer that IS DevOps" doesn't have the same ring to it) over about a year, I'd like to start a living FAQ/guide on how to get into this game.

I'm also posting it on Gist [here](https://gist.github.com/carlosonunez/83312c12f884444620a495ef60882945). I presume that I'll update that one more frequently.

# Materials Required

* A healthy love for learning (DevOps is very young and is evolving almost daily)
* Patience with being the "dumb guy in the room"

METHOD 1

This should roughly sort the items on distance in MySQL, and should work in SQLite.
If you need to sort them preciser, you could try using the Pythagorean theorem (a^2 + b^2 = c^2) to get the exact distance.

Get started with [Mocha] testing

Make a package.json file if you don't have one yet:

npm init
# just keep pressing enter.
# this will create the file `package.json`

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');

Those suck for maintenance and they're ugly.
