There's nothing like a bit of bit-twiddling to get the blood flowing in the morning :-)
This session covers some interesting and surprising low-level tricks that can help to accelerate your code, sometimes significantly. Some people might turn their noses up at these kinds of optimisations, but they occur in practice in a variety of places, including typical implementations of the C run-time and even well-known computer games.

Graham investigates techniques for automated bug discovery and testing that go beyond hitting the "Build and Analyze" button in Xcode. The session starts with an recap of unit testing, and explains how the Clang static analyzer does its work before moving on to advanced topics. These include embedding Clang and LLVM functionality into your own tools and automatic test generation.

Jonathan and Pieter will talk about the work and research on a key feature of Sofa's new app, Kaleidoscope.

Jonathan and Pieter discuss how the development of even a very low-level API can be shaped by taking a user-centric approach. Through experimentation it became clear that, instead of building on a popular open source implementation, a complete reimagination of both the API and the inner workings of this feature were needed.

This talk focuses on the technical challenges faced, concrete examples of solutions found and the pros and cons of spending a year reinventing the wheel.

We all use source control (don't we?), some of us write unit tests and we might even write some ad-hoc scripts now and then to automate some repetitive tasks. But how many of us have these three things working together for us all day, every day, watching for mistakes while freeing up our time to focus on the fun, creative stuff?
In this talk Gordon explores the benefits of continuous integration and shows that it’s not just useful for large teams and demonstrates how it can ease the pain of the solo indie developer. He also shows just how simple it is to get an automated build system up and running using Cruise Control.rb.

Creating an elegant screencast which will nicely complement screenshots and a well-designed website is a *must* in today's business. Most developers still fear making screencasts on their own, or simply don't have the money to pay for professional production or the tools necessary. This session Andreas gives an overview of the most valuable lessons he has learnt in over four years of screencasting. That is: the dos, the dont's, and the maybes.

With the release of iPad there is even more pressure on building applications with entertaining and eye catching user interface. What are the options you have... standard UI widgets: boring, Core Animation: dull, jumping into OpenGL: scary.... You haven't met Cocos2d, have you? This is the framework behind famous "Alice For The iPad" book/application.

Now it's your chance to see how Cocos2d brings the word 'easy' to sprite management, textures, transformations, actions, text rendering, particles and many more. No worries if it's jibberish for you. This session presents an overview of the major topics. Enough to let you gentle enter the world of Cocos2d for iPhone.

When creating our "National Rail Enquiries for iPhone" app, Dave spent a lot of time working with CoreLocation on the iPhone and iPod Touch. he developed some neat approaches for handling the inherent inaccuracies of the iPhone's Assisted GPS, and developed fast SQL techniques for querying a database of locations by distance.

In this session, he shares the discoveries he made and the tricks he developed, to help you create fast, useful and accurate location-based apps. He also provides an insight into how his "Next Train Home" feature is able to plan your best journey home from anywhere in the UK at the press of a button.

In this session, Klaas Pieter talks about what it's like to create, debug and maintain web apps with Cappuccino. He covers key differences between developing with Cappuccino and Cocoa and Sofa's rationale for using Cappuccino. Why did they pick it and, more importantly – 18 months later – would they make the same choice again?

There is lots of information out there about how to get an app to 1.0, but what happens when you get there?
Thiscovers general topics such as preparing your app to be as future proof as possible, balancing feature requests and bug fixes and dealing with user feedback, as well specific examples of mistakes made and challenges faced when developing LittleSnapper before and beyond its 1.0 state.

Extreme programming practice has been around for a long time now but has been traditionally associated with large projects with large teams. In this quick session Scotty looks at how extreme programming is made up of a number of elements such as iterative programming, test driven development , refactoring , code reviews and pair programming and relates how these practices may or may not suit solo and small team development projects.
