If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

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.

Minimum Viable Async with Node 6

With the release of Node 6.0.0, the surface of code that needs transpilation to use ES6 features has been reduced very dramatically.

This is what my current workflow looks like to set up a minimalistic and fast microservice using micro and async + await.

The promise

Managing plugins in Vim: The basics

Let's say the plugin is at a GitHub URL https://github.com/manasthakur/foo. First get the plugin by either cloning it (git clone https://github.com/manasthakur.foo.git) or simply downloading it as a zip (from its GitHub page).

Adding a plugin in Vim is equivalent to adding the plugin's code properly into its runtimepath (includes the $HOME/.vim directory by default). For example, if the layout of a plugin foo is as follows:

foo/autoload/foo.vim
foo/plugin/foo.vim

	<!doctype html>
	<html lang="en">
	<head>
	<meta charset="utf-8">
	<title></title>
	<meta name="description" content="">
	<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0;">
	<link rel="shortcut icon" href="/favicon.ico">
	<link rel="apple-touch-icon" href="/touch-icon.png">
	<link rel="stylesheet" href="fancy.css" />

	gem 'unicorn'

	gem_group :development, :test do
	gem 'rspec-rails'
	gem 'ffaker'
	end

	gem_group :development do
	gem 'guard'
	gem 'rb-inotify', require: false

	/** Async version of Array.prototype.reduce()
	* await reduce(['/foo', '/bar', '/baz'], async (acc, v) => {
	* acc[v] = await (await fetch(v)).json();
	* return acc;
	* }, {});
	*/
	export async function reduce(arr, fn, val, pure) {
	for (let i=0; i<arr.length; i++) {
	let v = await fn(val, arr[i], i, arr);
	if (pure!==false) val = v;
