Hi David,
I came across your profile online and wanted to reach out about Development
Opportunities here at Groupon. The company is growing, and we're always
looking for folks with solid skills that can make positive contribution to
our continued success. Any chance you'd be open to a quick conversation
about opportunities, or for any possible networking potential? If so, let me
know when you're free and we can set up a time to chat. Also, if you are
interested, it would be great if you could forward a current resume over
that I can take a look at. I look forward to hearing back from you! Please
let me know if you have any questions.

Print a stacktrace in Ruby or Rails without raising an exception

key is pretty much crucial for state perservation in React. As of React 0.13 it can't do the following things:

• Clone state

<Comp key={1} /><Comp key={1} />

• Preserve component state across different parents:

// ------------
// counterStore.js
// ------------

import {
  INCREMENT_COUNTER,
  DECREMENT_COUNTER
} from '../constants/ActionTypes';

const initialState = { counter: 0 };

class TodoStore extends BaseStore {
  // Constructor is executed in the  config phase.
  constructor(stores, initialState) {
    super(stores, initialState) // ensures initial state loads for SSR

    // Other store initialization...
  }

  // This is executed in the run phase, after all stores have initialized.
  storeDidInitialize(stores) {

 * Why does it return a thunk, though?
 *   Because in JS named arguments are opaque. There is no way of getting a function's named arguments list.
 *   e.g.
 *     const foo = function ({ a, b }) { }
 *     console.log(foo.arguments) // Throws. Ideally would return ['a', 'b'].

What is React Fiber? And how can I try it out today?

what?

React Fiber is an ongoing reimplementation of React's core algorithm. It is the culmination of over two years of research by the React team.
