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

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:

larrybolt

#!/usr/bin/env bash
set -o errexit
set -o nounset
set -o pipefail

# Automatically update your CloudFlare DNS record to the IP, Dynamic DNS
# Can retrieve cloudflare Domain id and list zone's, because, lazy

# Place at:
# /usr/local/bin/cf-ddns.sh
