operational pgp - draft

Operational PGP

This is a guide on how to email securely.

There are many guides on how to install and use PGP to encrypt email. This is not one of them. This is a guide on secure communication using email with PGP encryption. If you are not familiar with PGP, please read another guide first. If you are comfortable using PGP to encrypt and decrypt emails, this guide will raise your security to the next level.

A slightly modified implementation of Ken Perlin's improved noise that allows for tiling the noise arbitrarily.
public class Perlin {
public int repeat;
public Perlin(int repeat = -1) {
this.repeat = repeat;
}
public double OctavePerlin(double x, double y, double z, int octaves, double persistence) {
double total = 0;

Arggh Golang does not include a round function in the standard math package. So I wrote a quick one.
package main
import (
"log"
"math"
)
func Round(val float64, roundOn float64, places int ) (newVal float64) {
var round float64
pow := math.Pow(10, float64(places))

Complete collection of JavaScript destructuring. Runnable demos and slides about the same topic: http://git.mikaelb.net/presentations/bartjs/destructuring
// === Arrays
var [a, b] = [1, 2];
console.log(a, b);
//=> 1 2
// Use from functions, only select from pattern
var foo = () => [1, 2, 3];

Detect emoji unicode on a page, replace it with images (supplied by GitHub, for now). Goes great in your ~/.js
/**
*
* Here's a thing that will look through all the text nodes of a document, and
* upon encountering an emoji codepoint, will replace it with an image.
* For now, those images are pulled from GitHub, which isn't very nice, so I
* need to find a more suitable host.
*
* Much of this code was gleaned from staring at the minified GitHub JS.
