JS1k 2015 bare shim. This is loaded in an iframe dynamically. You can opt for an empty DOM during submit, a 2d canvas, or a webgl canvas. You can also specify max canvas width/height during submit, defaults to 100%. If empty, `a`, `c`, and `g` will obviously not exist. `top.reload()` replaces the iframe containing your demo with a new instance, …
<!doctype html>
<html style="margin: 0; padding: 0; border: 0; width: 100%; height: 100%;">
<head>
<meta charset="utf-8">
</head>
<body style="margin: 0; padding: 0; border: 0; width: 100%; height: 100%;">
<canvas style="display: block; width: WIDTHpx; height: HEIGHTpx;" width="WIDTH" height="HEIGHT"></canvas>
<script>
// shim...
var a = canvas;

Merge wiki updates that are on a fork of your repo.

Merge Wiki Changes From A Forked Github Repo

This is inspired (or basically copied) from How To Merge Github Wiki Changes From One Repository To Another, by Roman Ivanov, and serves to ensure that should something happen to the original article, the information remains nice and safe here.

Terminology

OREPO: original repo - the repo created or maintained by the owner

FREPO: the forked repo that presumably has updates to its wiki, not yet on the OREPO

Allow Node.js to bind to privileged ports without root access on Ubuntu

How to: Allow Node to bind to port 80 without sudo

TL;DR

Only do this if you understand the consequences: all node programs will be able to bind on ports < 1024

sudo setcap 'cap_net_bind_service=+ep' /usr/local/bin/node

Important: your node location may vary. Use which node to find it, or use it directly in the command:
