In this tutorial we're going to build a set of parser combinators.

What is a parser combinator?

We'll answer the above question in 2 steps.

What is a parser?
and, what is a parser combinator?

So first question: What is parser?

Serverless plugin author's cheat sheet

This cheat sheet provides a detailed overview of the exposed lifecycle events and available commands (and entrypoints) of the Serverless framework, that can be hooked by plugins (internal and external ones). The document is structured by the commands invoked by the user.

Memory Leak Testing in 2017

Hi, I am Andy, creator of leakage - the node-powered memory leak testing library.

TL;DR: If you want to see me perform a spoken word poem about JavaScript in front of 1000 people (and on video), please ⭐ star this gist. If you're on mobile, you'll need to request desktop site.

JavaScript Slam Poetry

In the background script we have:

chrome.webRequest.onBeforeRequest.addListener(function (details) {
  if (details.method === 'HEAD') {
    if (details.url.endsWith('?start')) {
      ringSound.play();
    } else if (details.url.endsWith('?stop')) {
      ringSound.pause();
 ringSound.currentTime = 0;

Raise Open File Limits in OS X

in OS X 10.4 to macOS sierra 10.12 and maybe higher!

Create Launcher Script:

`/Library/LaunchDaemons/limit.maxfiles.plist`

Copy this entire code block and paste it into your terminal and push Return to create this file for you with correct permissions. It will (probably) ask for your password:

	dialog {
	position: fixed;
	top: 50%;
	left: 50%;
	right: auto;
	padding: 30px;
	transform: perspective(500px) translate(-50%, -50%);
	background: linear-gradient(to bottom, #FFF, #F4F4F4) #FFF;
	border: none;
	border-radius: 3px;
