Conventions

A = [xA, yA] is a point on the 2D plane. Same for B, C, ...
lengths are in any unit (ex: pixels)
code snippets are in JavaScript

Degrees to radians

angleRad = angleDeg * Math.PI / 180;

I18n with Records

Goals:

Elm's typechecker enforces that

each localization has all the same messages.
the messages you are referring to in your view code exist.

Only the localized strings for the current locale are sent across the wire
Messages which have interpolations are typechecked as well

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.

2015-01-29 Unofficial Relay FAQ

Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).

	# problem: when presenting, I want to obscure
	# my prompt to act like it's at root of file system

	# solution: this theme lets you set a ENV to the path

	# features while in that path
