Welcome to the session on coming to grips with the awesome language that is Objective-C. Throughout this session, my aim is to take you from no prior experience with Objective-C to using it confidently in your own applications. This isnʼt a rush job - so donʼt expect to just skim through the basics and be away - weʼll be going through not just the bare essentials, but also the best practices you can apply to ensure your code is the best it can be. Letʼs jump straight in!

SMS is a worldwide technology used by almost everyone with a cell phone. Despite having a much greater reach than the smartphone market, SMS programming receives far less coverage and often remains uncapitalized. In this session, I will show you how to create a web site signup form that allows users to enter a mobile number. I will then show you how to use PHP for server-side phone number verification to check that the mobile number the user has entered is actually his mobile phone. Along the way, we will use jQuery to perform client-side validation and CodeIgniter as our development framework.

More and more people visit the web on mobile devices and this means that your website needs to be optimized for a mobile experience. In this session, we'll take a look at how you can leverage WordPress to accomplish this goal.

This session is all about working with the push notification features of iOS 3.0+. It will cover everything you need to do to get push notifications working in your application, such as registering for notifications, configuring your application in the iOS Provisioning Portal, sending notifications to Apple’s Push Notification Service (APNS), and handling them in your application. Let's ge started.

Thanks to the wide adoption of libraries like jQuery and Mootools, JavaScript’s popularity has skyrocketed in the last few years. However, in the process, an interesting thing occurred: many newer developers are learning these libraries without taking the time to actually learn about raw JavaScript techniques. What percentage of jQuery users don’t know how to fade out an element with only raw JS? My guess is that it’s much higher than many would think.
