1. Get your IP Address

echo `ifconfig $(netstat -nr | grep -e default -e "^0\.0\.0\.0" | head -1 | awk '{print $NF}') | grep -e "inet " | sed -e 's/.*inet //' -e 's/ .*//' -e 's/.*\://'`

2. Modify your hosts file

No, `.mjs` is not a Python 3-like split

Seen a few tweets on this. I want to dispel some FUD.

Node is probably going to introduce a new file extension for JavaScript modules, .mjs. The reasons for this are long and perilous, and trying to summarize the discussion that led to it is maddening. The short version is that ES6 modules have different semantics from existing scripts, and need to be executed differently. In browsers, this is done with <script type="module">. In Node, this will be done by analyzing the file extension of the imported file.

I'll be honest: I don't love this solution! I was rooting for the TC39 counter-proposal. But I also understand the solution that the Node developers chose, and why they chose it.

The new file extension is a good enough solution. You can read the [draft spec](https://github.com/nodejs/node-eps/

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

@kangax's ES6 quiz, explained

@kangax created a new interesting quiz, this time devoted to ES6 (aka ES2015). I found this quiz very interesting and quite hard (made myself 3 mistakes on first pass).

Here we go with the explanations:

Question 1:

(function(x, f = () =&gt; x) {

##Setting Up Meta Data Fields##

Install/Activate Custom Fields Suite WordPress Plug-In, Docs
Create new Field Group called Gallery Meta Data
Add a Field called Gallery Images and set the type as Loop, fill out the rest of the required fields, for placement rules attach this custom meta data to WordPress type of Page or whatever your requirements are. Hit Publish Figure 1
Next, Add additional field called Image. Hit Update Figure 2
Next, drag Image, field we just created, under the Gallery Images it needs to be a child of the Loop, Hit Update Figure 3

##Adding Meta Data to Pages##

tl;dr we're lazy, we're coders.

Let's make use of that.

We don't like to start off new projects and write all the booooring boilerplate
We like to fiddle with code and fix it
We like recognition
We're quickly bored

Hence, I present to you my idea:
