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.

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

	import java.io.BufferedReader;
	import java.io.Closeable;
	import java.io.IOException;
	import java.io.InputStream;
	import java.io.InputStreamReader;
	import java.util.NoSuchElementException;

	public class ShadReader implements Closeable {
	private static final int BUFFER_SIZE = 1024;

	hsqldb - select 1 from INFORMATION_SCHEMA.SYSTEM_USERS
	Oracle - select 1 from dual
	DB2 - select 1 from sysibm.sysdummy1
	mysql - select 1
	microsoft SQL Server - select 1 (tested on SQL-Server 9.0, 10.5 [2008])
	postgresql - select 1
	ingres - select 1
	derby - values 1
	H2 - select 1
	Firebird - select 1 from rdb$database

	create database sonarqube character set 'utf8';

	create user 'sonarqube'@'localhost' identified by 'password';

	grant all privileges on sonarqube.* TO 'sonarqube'@'%';

	flush privileges;

	apply plugin:'java'
	apply plugin:'idea'

	repositories { mavenCentral() }

	dependencies {
	testCompile 'junit:junit:4.11'
	}

	task makeDirs(description:'make all dirs for project setup') << {


	I want to implement a simple simulator (Cellular automaton) and can use both java.util.concurrent.* or java.util.stream.* for parallel execution (later produces nicer code). With Java9 I want to execute on the GPU. Which package to use to prepare for GPU computation? Will there be a .parallelGPUStream()?

	import org.junit.Test;

	import java.util.Arrays;

	public class IntToBitesTest {

	@Test
	public void intToBytes() throws Exception {
	int n = 1234567890;
	byte[] a = new byte[4];
