OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

Client-side SSL

For excessively paranoid client authentication.

Using self-signed certificate.

Create a Certificate Authority root (which represents this server)

Organization & Common Name: Some human identifier for this server CA.

openssl genrsa -des3 -out ca.key 4096
openssl req -new -x509 -days 365 -key ca.key -out ca.crt

Foreword

Build your own private, encrypted, open-source Dropbox-esque sync folder

Prerequisites:

One or more clients running a UNIX-like OS. Examples are given for Ubuntu 12.04 LTS, although all software components are available for other platforms as well (e.g. OS X). YMMV
A cheap Ubuntu 12.04 VPS with storage. I recommend Backupsy, they offer 250GB storage for $5/month. Ask Google for coupon codes.

Software components used:

Unison for file synchronization
EncFS for folder encryption

WebSockets + Reflux + React

Using WebSockets, React and Reflux together can be a beautiful thing, but the intial setup can be a bit of a pain. The below examples attempt to offer one (arguably enjoyable) way to use these tools together.

Overview

This trifect works well if you think of things like so:

Reflux Store: The store fetches, updates and persists data. A store can be a list of items or a single item. Most of the times you reach for this.state in react should instead live within stores. Stores can listen to other stores as well as to events being fired.
Reflux Actions: Actions are triggered by components when the component wants to change the state of the store. A store listens to actions and can listen to more than one set of actions.
