Follow these steps before trying to run any code.

First, generate a Certificate Authority (CA).

openssl genrsa -out rootCA.key 2048

Second, self-sign it.

BNF parsing

Toy weekend project: make a parser-parser!

This takes in a grammar given in Bakus-Naur Form (BNF), and a program that was written in the provided grammar, and produces an image of Syntax Tree using graphviz.

ANSI Escape Sequences

Standard escape codes are prefixed with Escape:

Ctrl-Key: ^[
Octal: \033
Unicode: \u001b
Hexadecimal: \x1B
Decimal: 27

How to transform an SVG into a data URI

by Jenny Knuth, based on the work of Chris Coyier and Taylor Hunt

A data URI is a nice way to include a web resource without needing to make an HTTP request. Chris Coyier explains the technique nicely in Probably Don't Base64 SVG.

While a PNG might use Base64 encoding, for SVG, there is a better way.

Taylor Hunt's experiments led to this solution for optimizing SVGs in data URIs:

"So the best way of encoding SVG in a data URI is data:image/svg+xml,[actual data]. We don’t need the ;charset=utf-8 parameter (or the invalid ;utf8 parameter…), because URLs are always ASCII."
