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

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

Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

	import React from 'react';

	import * as My from './components/my-components.js';

	export default class App extends React.Component {
	render() {
	return (
	<div>
	<My.Foo />
	<My.Bar />

	select.form-control + .chosen-container.chosen-container-single .chosen-single {
	display: block;
	width: 100%;
	height: 34px;
	padding: 6px 12px;
	font-size: 14px;
	line-height: 1.428571429;
	color: #555;
	vertical-align: middle;
	background-color: #fff;
