Push Notifications – Device, Protocol and Server recording available icon
Mark Aufflick, Pumptheory

Audience: Intermediate

Abstract:

Apple Push Notifications are an integral part of many applications, from games like “Words With Friends” to VOIP call notification, but for the non-expert developer they can be a source of mystery. Apple’s “Local and Push Notification Programming Guide” provides details of the binary protocol, SSL certificates and other details which are hardly beginner material. Additionally the guide makes little mention of correct UTF encoding and other small details which create more difficulty for those unfamiliar with data encodings etc. And finally a persistent server is required which can handle the protocols. This talk will take attendees through: an understanding of the service overall; the protocol and its limitations; responding to notifications in the iOS application; approaches to implementing a server in Perl, Python or Ruby.

Speaker Bio:

Mark Aufflick has been involved in the Apple industry since his first job in 1995 and finally put his Computer Science degree to use becoming a freelance developer in 2000. Since then he has developed back end, web and gui applications for various Unix platforms, MacOS and iOS – for both corporate giants and small businesses. Mark has presented on programming topics in fora such as Sydney University’s Web Engineering Group and CocoaHeads. These days Mark is an iOS and Mac developer with his company Pumptheory as well as the convenor of Sydney CocoaHeads.

Audience: Advanced

Abstract:

OpenCL* (Open Computing Language) is an open, royalty-free, cross-platform standard specifically designed for general purpose parallel programming of heterogeneous systems, including modern desktop and workstation class multi-core processors (CPUs), graphics processing units (GPUs), and other accelerators such as Cell and digital signal processors (DSPs). The standard includes an API for coordinating execution between devices and a cross platform parallel programming language. Based on ISO C99, the OpenCL-C language provides a well-defined execution environment with strict precision requirements, allowing device agnostic kernel methods to be written which can be run on any supported OpenCL device. The OpenCL standard supports task-based and data-based parallel computing, features consistent numerical requirements based on the IEEE standard for floating-point arithmetic (IEE 754), defines a configuration profile for handheld and embedded devices and efficiently interoperates with OpenGL, OpenGL ES, and other graphics APIs.

This talk will be split into two parts. The first section will cover the fundamentals of OpenCL and dive into introductory code examples showing how to use OpenCL in custom applications. The second section will look at optimizations and debugging techniques, and show how OpenCL can be combined with OpenGL for advanced graphics programming.

Awesome Things You’ve Missed in Python recording available icon
Chris Neugebauer, University of Tasmania

Audience: All (some Python knowledge assumed)

Abstract:

The Python Programming Language has always allowed rapid development of applications for a wide variety of systems, including Mac OS, where it is a first-class Cocoa language. You may have coded in Python before, but as a constantly-evolving language, the Python that you learnt a few years ago is probably not the best possible Python that you could write today. This talk shows how to write better and safer Python code more quickly by taking advantages of recent features that appear in Python 2.6, the default version newly included in Snow Leopard. This talk will also show you how to future-proof your code in preparation for the transition to the backwards-incompatible Python 3 (which any actively-developed Python codebase will need to eventually make).

Speaker Bio:

Chris recently completed a First Class Honours Degree in Computer Science at the University of Tasmania.

Introduction to Core Animation recording available icon
Daniel Woo, University of New South Wales

Audience: Beginner

Abstract:

Core Animation takes the low-level drudgery out of animation coding. The focus isn’t on responding to timing events, it shifts to defining where objects need to be, or how much opacity or rotation should be applied and when. The tweening details are left to the framework. In fact, several properties can be animated at the same time. In this session you will learn the basics of Core Animation and how to start coding your user interface to include animation. We will also touch on the impact animation has on the user experience.

Speaker Bio:

“We’re going to change the world, one person at a time” is a great quote from Tim Lucas who was in the first cohort of students in Daniel’s User Interface Design and Consutruction (COMP4511) course. The vision was to fuse object-oriented programming and user interface design in a practical way using Cocoa/Obj-C as the principle teaching language. Real world tools for students just starting out; an incredible confidence booster. A subset of that course became the AUC Cocoa Course which has been running now for 6 years.

Daniel’s work spans boundaries: art+science collaborations on the Baltic Sea, Sydney Harbour, Singapore and Belfast; the DigiMacq iPhone app lauched for Parramatta City Council; Rural Allied Health Professionals and Assistive Technology for the Independent Living Centre; Assistive Technologies for the Blind and Visually Impaired; iPod in Special Needs Education; First Australians Web (SBS TV) Usability Evaluation.

The motivation is quite simple: create an Australian-based launching pad for the careers of software designers and developers to deliver to the world great technologies and engaging user experiences: one person at a time.
