Created March 23, 2020 15:13
Simple example of uploading to S3 from the filesystem with Node.js - If you're trying to learn how to do this, checkout Fullstack Node.js https://newline.co/fullstack-nodejs
const fs = require('fs')
const AWS = require('aws-sdk')
const { promisify } = require('util')
const s3 = new AWS.S3()
s3.uploadP = promisify(s3.upload)
const params = {
Bucket: 'fullstack-printshop',
Key: 'profile-photos/thedude.jpg',
Body: fs.createReadStream('thedude.jpg')
}

Deconstruction of the curves on @Wattenberger's Thinking in Hooks Post
// This code is from: https://github.com/Wattenberger/Wattenberger-2019/blob/07024a820011988f5fbefed21161b1111f38e710/src/components/Blog/posts/Hooks/Hooks.jsx#L451-L470
// It generates the SVG path for the curve between two lines on the post "Thinking in React Hooks", located here: https://wattenberger.com/blog/react-hooks
//
// It's a good idea to pull up the documentation on SVG paths here: https://www.w3.org/TR/SVG/paths.html
//
// As you may know, SVG paths are specified by a string where a
// letter is the "command" and the numbers following are the "arguments"
//
// We'll be using 4 commands:

With Bitcoin 0.7 it's possible to keep your private keys
entirely offline without third party software.
In this example we have two hosts [offline] which is
totally offline and without a copy of the blockchain
and [online] which is a regular online node, both
running bitcoin 0.7.
