Dynamic Data on IPFS: An Introduction to Textile's Buckets and Threads

This document: https://tinyurl.com/ybk38mfh
Slides from intro presentation: https://tinyurl.com/y8hxgrq2

Description

In this workshop we’re going to cover tools for building engaging apps, for real users, dealing with real data. We’ll focus on JavaScript app building and we’ll show you simple and fast ways to add IPFS, IPNS, and even potentially Filecoin so you can create interoperable & unstoppable data for your users.

What we’ll cover:

We'll cover in introduction to Textile’s Threads, Buckets, and Hub tools. We’ll also cover some command-line (CLI) actions, and Textile’s JavaScript Client(s). To prepare, we encourage you to install a few things before we get started:

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

JavaScript Crypto Libraries

List some crypto libraries for JavaScript out there. Might be a bit out dated. Scroll to the bottom.

WebCryptoAPI

http://www.w3.org/TR/WebCryptoAPI/

This specification describes a JavaScript API for performing basic cryptographic operations in web applications, such as hashing, signature generation and verification, and encryption and decryption. Additionally, it describes an API for applications to generate and/or manage the keying material necessary to perform these operations. Uses for this API range from user or service authentication, document or code signing, and the confidentiality and integrity of communications.

  I've wrapped Makoto Matsumoto and Takuji Nishimura's code in a namespace
  so it's better encapsulated. Now you can have multiple random number generators
  and they won't stomp all over eachother's state.
  
  If you want to use this as a substitute for Math.random(), use the random()
  method like so:
  
  var m = new MersenneTwister();
