I heard from GitHub Two-Factor Authentication](https://github.com/blog/1614-two-factor-authentication) nearly a couple of days ago when I was reading my RSS feed. I enabled it and couldn' push to any of my repositories anymore. Learn in this blog post how to fix it.

Two-Factor Authentication

"Is a process involving two stages to verify the identity of an entity trying to access services in a computer or in a network". Github solves this authentication with sending an SMS to a device which wants to push to their platform.

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

	Backup:
	docker exec -t -u postgres your-db-container pg_dumpall -c > dump_`date +%d-%m-%Y"_"%H_%M_%S`.sql

	Restore:
	cat your_dump.sql \| docker exec -i your-db-container psql -Upostgres

	dash_id=xxxx
	api_key=xxx
	app_key=xxx

	# 1. export
	curl -X GET "https://app.datadoghq.com/api/v1/dash/${dash_id}?api_key=${api_key}&application_key=${app_key}" > dash.json

	# 2. edit dash.json
	move "graphs", "title", "description" up one level in the json hierarchy, from being beneath "dash" to being at the same level

	NOTE: This document is OLD - and most of the tips here are probably outdated, since newer versions of Javascript have been
	released over the years - with newer optimizations and more emphasis on optimizing newly supported syntax.
