Rapid prototyping with Relay

Relay makes data fetching in React apps simpler, by letting you declare the data needs of your components instead of writing complex imperative code. React, Relay, GraphQL and the other complementary tools are changing how apps are built.

Advanced React.js Performance

Performance is one of the reasons why React.js is so popular for building complex, highly interactive web applications. It became the go-to library for developers who don’t like to make compromises for technical reasons when building awesome user experiences. However even with React.js it still can be easy to hit it’s performance limits.

In this lightning talk Daniel will go beyond the basics of shouldComponentUpdate and immutable data structures and will discuss how to correctly instrument, measure and optimize performance in complex React apps. He will help you understand the overhead of different parts of the React component lifecycle, how some of it’

“time” (string)– Required - Time when the schedule occurs in extended ISO 8601:2004 format. Note time is always measured in the bridge in UTC time. 
The set value that is supported is as follows:-
Non-recurring schedule – [YYYY]:[MM]:[DD]T[hh]:[mm]:[ss]
Non-recurring schedule with random– [YYYY]:[MM]:[DD]T[hh]:[mm]:[ss]A[hh]:[mm]:[ss]
Recurring schedule – W[bbb]T[hh]:[mm]:[ss]
Recurring schedule with random – W[bbb]T[hh]:[mm]:[ss]A[hh]:[mm]:[ss]
Timer – PT[hh]:[mm]:[ss]
Timer with random element - PT[hh]:[mm]:[ss] A[hh]:[mm]:[ss]
Recurring timer – R[nn]/PT[hh]:[mm]:[ss]
Recurring timer with random element – R[nn]/PT[hh]:[mm]:[ss]A[hh]:[mm]:[ss]

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.
