MessagePack for Ruby version 5

Today, I released the new version of MessagePack for Ruby!

Even faster
New API
API reference

Even faster

I rewrote all the code and achieved significant performance improvement, especially for serialization. I compared the new version to the old version (v4) using ruby-serializers benchmark, and the new version is faster for all data sets including Twitter, Image, Integers, Geo and 3D model.

Building our first Camera App

In the first ever SwiftCast TV screencast. We will teach you how to build a Camera application that allows you to take a photo, select an existing photo, and view our selected photo. Let’s get started.

Chapter 1: Setting up our Application

Create a new Application by clicking "Create a new Xcode project". When asked to Choose a template for your new project, we are going to select "Single View Application" under iOS/Application. Then click the "Next" button.

	class TaskApp extends Spine.Controller
	# Add event listeners
	events:
	"submit form": "create"
	"click .clear": "clear"

	# Create some local variables refering to elements
	elements:
	".items": "items"
	"form input": "input"

	def main():
	for number in range (100, 201):
	if number % 5 == 0 and number % 7 == 0:
	return print(number,'World Cup!')

	if number % 5 == 0:
	return print(number, 'World')

	if number % 7 == 0:
	return print(number, 'Cup')

	func requestFingerprintAuthentication() {
	let context = LAContext()

	let authenticationReason: String = "To display a message to the user"

	if context.canEvaluatePolicy(LAPolicy.DeviceOwnerAuthenticationWithBiometrics, error: &authError) {
	}
	}

	context.evaluatePolicy(LAPolicy.DeviceOwnerAuthenticationWithBiometrics, localizedReason: authenticationReason, reply: {
	(success: Bool, error: NSError?) -> Void in

	console.log fizzbuzz
