"New Features in iOS 7 for Developers" by Adrian Kosmaczewski

This talk will provide a quick overview of the new possibilities offered by iOS 7 for app developers. It targets iOS developers familiar with the APIs of iOS 6, and will give them up-to-date information about cool new features that can be used now in new applications (as well as some painful gotchas). The presentation will include live demos.

"Architecture for scalable and high performance applications. An introduction to CQRS and Axon Framework" by Allard Buijze

Many web applications nowadays are built using the same architectural principles: a layered architecture and, more often than not, an anaemic domain model. Although this style is familiar to many developers and easy to set up, it lacks the capability to help us cope with increasing complexity and doesn't allow applications to scale very well. In this presentation, Allard will introduce another architectural principle: Command and Query Responsibility Segregation (CQRS). CQRS promotes the decoupling of components that change an application's state (the commands) from the components that provide information about the current state (the queries). This architectural approach makes it easier to handle increasing complexity and ensure the application's ability to scale. You will also see how CQRS can help build high performance applications and provide business value by storing valuable information about the application's history. During the session, we will also cover the practical aspects and look at what it takes to build a CQRS based application in Java. We will see how the Axon Framework can help Java developers to quickly set up a CQRS infrastructure.

Short Bio
Allard Buijze is software architect at Trifork Amsterdam, which delivers software development, consultancy and training services to both national and international organizations. As an architect, he is responsible for the technical choices in his projects and investigates technologies for their potential in the diversity of projects Trifork does. For the last decade, he has been developing and designing enterprise applications for both large-scale and smaller projects. His focus has always been on clean application design, maintainability and testing. The training of co-developers is a very important part thereof. For several years, he has been investigating and applying CQRS to a number of projects. As a result, he created the Axon Framework, an open source Java framework that helps developers create scalable and extensible applications by providing the building blocks that CQRS based infrastructures typically require. Axon has a growing community and has already been successfully introduced in several projects around the world.
