Speed up zsh compinit by only checking cache once a day.
# On slow systems, checking the cached .zcompdump file to see if it must be
# regenerated adds a noticable delay to zsh startup. This little hack restricts
# it to once a day. It should be pasted into your own completion file.
#
# The globbing is a little complicated here:
# - '#q' is an explicit glob qualifier that makes globbing work within zsh's [[ ]] construct.
# - 'N' makes the glob pattern evaluate to nothing when it doesn't match (rather than throw a globbing error)
# - '.' matches "regular files"
# - 'mh+24' matches files (or directories or whatever) that are older than 24 hours.

react isomorphic 原理
- 我想要挑戰isomorphic,但目前好像比較少redux配isomorphic又配上webpack的方案
- 這個範例可看,最近全部改寫過
- https://github.com/coodoo/react-redux-isomorphic-example
- 注意下面幾點
- js/bootClient.js 與 js/bootServer.js
- bootServer.js 負責做 server-render

How to migrate a Homebrew-installed PostgreSQL database to a new major version (9.3 to 9.4) on OS X. See upgraded version of this guide: http://olivierlacan.com/posts/migrating-homebrew-postgres-to-a-new-version/

This guide assumes that you recently run brew upgrade postgresql and discovered to your dismay that you accidentally bumped from one major version to another: say 9.3.x to 9.4.x. Yes, that is a major version bump in PG land.

First let's check something.

brew info postgresql

The top of what gets printed as a result is the most important:

Alternative to Higher-order Components

React now supports the use of ES6 classes as an alternative to React.createClass().

React's concept of Mixins, however, doesn't have a corollary when using ES6 classes. This left the community without an established pattern for code that both handles cross-cutting concerns and requires access to Component Life Cycle Methods.

In this gist, @sebmarkbage proposed an alternative pattern to React mixins: decorate components with a wrapping "higher order" component that handles whatever lifecycle methods it needs to and then invokes the wrapped component in its render() method, passing through props.

While a viable solution, this has a few drawbacks:

  1. There's no way for the child component to override functionality defined on the higher order component.

JSX, a year in

Hi Nicholas,

I saw you tweet about JSX yesterday. It seemed like the discussion devolved pretty quickly but I wanted to share our experience over the last year. I understand your concerns. I've made similar remarks about JSX. When we started using it Planning Center, I led the charge to write React without it. I don't imagine I'd have much to say that you haven't considered but, if it's helpful, here's a pattern that changed my opinion:

The idea that "React is the V in MVC" is disingenuous. It's a good pitch but, for many of us, it feels like in invitation to repeat our history of coupled views. In practice, React is the V and the C. Dan Abramov describes the division as Smart and Dumb Components. At our office, we call them stateless and container components (view-controllers if we're Flux). The idea is pretty simple: components can't
