How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

Free O'Reilly books and convenient script to just download them.

Thanks /u/FallenAege/ and /u/ShPavel/ from this Reddit post

How to use:

Take the download.sh file and put it into a directory where you want the files to be saved.
cd into the directory and make sure that it has executable permissions (chmod +x download.sh should do it)
Run ./download.sh and wee there it goes. Also if you do not want all the files, just simply comment the ones you do not want.

libevent vs libuv

Comparing libevent and libuv. My upfront biased: I want to like libevent. However, I want to objectively compare the two and make an informed decision.

What versions are we comparing?

libevent 2.0.22 (Stable) [2014-01-05]
libuv 1.8.0 (Stable) [2015-12-15]

My preferred code style is 2-space K&R. This is intended to provide a justification for this style.

Why K&R?

K&R style has the following properties:

Provides symmetric size (in terms of screen space consumed) between the opening and closing syntax of a clode block.
Forces no empty or meaningless lines, thereby avoiding artificial distance between related things that should be together.
Consumes the minimum vertical space while keeping the opening and closing syntax of a block on separate lines from the content.

	May be wrong sometimes, as it's just the result of my research here and there.
	If it helps you, give me a shout!)

	Ordered dithering is a technique used to reduce - deliberately! - the precision of an image.
	Motivation : artistic (mainly ?), color quantization --> reduce the number of color in an image
