what's an action for redux? — It's an object describing what's happening. It's the only source of information fir the store. It sends the data from the app to the store. It always has a key called 'type'

advantage of immutability in Redux?

Redux architecture revolves around a strict unidirectional data flow.

Data lifecycle: 1. You call store.dispatch(action) 2. Redux store calls the reducer function 3. combine output of multiple reducer into on single state tree 4. Redux store returns the complete state tree (returned by the root reducer)

Ex with a combineReducers() function todos(state = [], action) { // Somehow calculate it... return nextState } ​ function visibleTodoFilter(state = 'SHOW_ALL', action) { // Somehow calculate it... return nextState } ​ let todoApp = combineReducers({ todos, visibleTodoFilter })

React bindings for Redux embrace the idea of separating presentational and container components.

Container Components: How things work (data fetching, state updates) Dispatch Redux actions Are usually generated by React Redux

Presentational Components How things look (markup, styles) Invoke callbacks from props to change data Are written by hand

You could write a container component by hand, but we suggest instead generating container components with the React Redux library's connect() function, which provides many useful optimizations to prevent unnecessary re-renders.

To use connect(), you need to define a special function called mapStateToProps that tells how to transform the current Redux store state into the props you want to pass to a presentational component you are wrapping.

In addition to reading the state, container components can dispatch actions. In a similar fashion, you can define a function called mapDispatchToProps() that receives the dispatch() method and returns callback props that you want to inject into the presentational component.

Connecting react and redux: import { connect } from 'react-redux' ​ const VisibleTodoList = connect( mapStateToProps, mapDispatchToProps )(TodoList) ​ export default VisibleTodoList

Redux component <Provider> : is used to magically make the store available to all container components in the application without passing it explicitly. You only need to use it once when you render the root component:

How do you use <provider> ?

Subtle impressions for which words are quite too coarse a medium

Law is order in liberty, and without order liberty is social chaos.

I want to change things with everything I do, not for the sake of changing things, but for the sake of taking greater and greater risks, or how minimalist I might be able to be, or how I can involve elements or ingredients in music videos that are not musical, for instance.

In OK Computer, the guitar was already moving towards a tone generator as well as a riff generator.

Making comic adaptations means making a lot of choices - you need to adjust the pacing, the dialogue, and in this case, a lot of the cultural references.

You don't get points for leaving the chin open.

You learn history in school, and you have a reverential feeling toward it. But by being irreverent, it feels current.

I always thought that poetry is the verdict that others give to a certain kind of writing. So to call yourself a poet is a kind of dangerous description. It's for others; it's for others to use.

I love painting so much that nothing else matters.

Perhaps it would be better for science, that all criticism should be avowed.

When I am shooting a film, and it has a big schedule, I make sure that I take a week off with the family. It gives you new energy.

It was such a pleasure to work with Eugene Levy. What a treat. That's a guy I grew up watching as a kid. Guys like that, they were hilarious and didn't have to be super vile or X-rated.

Everything I do, I put my full heart into. I don't want to be just another actor, another singer, another artist. I want to invent history.

Our country's founders cherished liberty, not democracy.

You sit there waiting for the RED LIGHT to go on. You could be sitting there for five minutes, waiting, while the producer talks to the engineer. Then the light goes on you know that you mustn't make a mistake for at least 4 minutes.

I think I've got wiser.

If someday they say of me that in my work I have contributed something to the welfare and happiness of my fellow man, I shall be satisfied.

In this age of vampires, what I love about 'True Blood' the most is that it's a post-modern take on it. 'Sookie Stackhouse' series author Charlaine Harris and 'True Blood' creator Alan Ball turned that whole mythology upside-down... It's not just about vampires. It's about a lot of different things.

Generally speaking I would say I enjoy the smaller films more because there's a less sense of pressure and often the material is more unusual.

Once kick the world, and the world and you will live together at a reasonably good understanding.

Tiny steps will get you to your goal months and months sooner. A little is better than a lot.
