A short introduction to animating Shape in React Native

This note explains the basic idea of the animated chart in https://github.com/shuhei/Compare.

Before animation

We can draw a shape if we have:

shuhei

function Foo(props) {
  return (
    <div className="yes">
    	<p>Hello, {props.name}</p>
    </div>
  );
}

function FooCompiled(props) {
  return (

Result

There were not memory leaks detected for:

• error on the unzip stream
• error on the request object

Couldn't get error on the response object. When the connection is destroyed, request object emits an error.

WIP: Typing HOCs with recompose

It's hard to keep prop types of underlying components of HOCs. Even the official documentation is not working well. It's even harder to have multiple HOCs typed and maintain with peer developers. Here comes recompose, the HOC utility module. If we have recompose properly typed, we can omit typing of our own HOCs taking advantage of recompose and flowtype's type inference.

recompose still doesn't have official flowtype definition, but there are some efforts:

• acdlite/recompose#241
• flow-typed/flow-typed#624

This gist is an effort to make it happen based on the PRs above.

It was fastest without maxSockets until the client gets Error: connect ECONNRESET 127.0.0.1:8080. maxSockets avoided the error but didn't work for performance.

Karabiner currently doesn't work on Mac OS X Sierra. This note is to simulate some of my favorite configurations on Karabiner on Sierra.

• Ctrl + hjkl -> arrow keys
• Space + some key -> Shift + the key (still quite buggy)

Karabiner Elements

Put the karabiner.json at ~/.karabiner.d/configuration/karabiner.json.
