How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

Facebook: Unfollow people and pages

See comments section for more up-to-date versions of the script. The original script is from 2014 and will not work as is.

Open news feed preferences on your Facebook menu (browser)
Click people or pages
Scroll down (or click see more) until your full list is loaded
Run the script in your browser console

Facebook will block this feature for you while you use it, depending on how much entities you try to unfollow. It automatically unblocks in a couple of hours and you will be able to continue.

Orthodox C++

What is Orthodox C++?

Orthodox C++ (sometimes referred as C+) is minimal subset of C++ that improves C, but avoids all unnecessary things from so called Modern C++. It's exactly opposite of what Modern C++ suppose to be.

Why not Modern C++?

How to generate and apply patches with git?

It sometimes happen you need change code on a machine from which you cannot push to the repo. You’re ready to copy/paste what diff outputs to your local working copy.

You think there must be a better way to proceed and you’re right. It’s a simple 2 steps process:

1. Generate the patch:

git diff &gt; some-changes.patch

Common Options

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar <file name> File to save response cookies to.

	#!/bin/bash
	#
	# Example of how to parse short/long options with 'getopt'
	#

	OPTS=`getopt -o vhns: --long verbose,dry-run,help,stack-size: -n 'parse-options' -- "$@"`

	if [ $? != 0 ] ; then echo "Failed parsing options." >&2 ; exit 1 ; fi

	echo "$OPTS"

	#!/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

	#!/bin/sh

	# Take a PDF, OCR it, and add OCR Text as background layer to original PDF to make it searchable.
	# Hacked together using tips from these websites:
	# http://www.jlaundry.com/2012/ocr-a-scanned-pdf-with-tesseract/
	# http://askubuntu.com/questions/27097/how-to-print-a-regular-file-to-pdf-from-command-line
	# Dependencies: pdftk, tesseract, imagemagick, enscript, ps2pdf
	# Would be nice to use hocr2pdf instead so that the text lines up with the PDF image.
