Track: Architecture

Every program, from a tiny script to a large trading system, has an architecture. The architecture is the internal structure and interactions of the program as well as the environment with which it interacts. Should you use relational databases, graph databases or persistent maps? Is a distributed core better than a monolithic? What is Event Sourcing and is that right for my situation? Is functional programming better than imperative for this task? Why? Why not? When? Where? In architecture there are no simple answers, it depends on the context; the environment, the people, the requirements, etc. Whether you plan it or not, at the end of the day, an architecture is what you get. It is truly better to plan it! Come learn the tricks of the trade at Oredev!

Java provisioning in the cloud

This session will overview cloud provisioning tools written in java and clojure.  First, we'll overview general provisioning concerns and how devops relates to the java landscape.  We will show examples that work on several clouds via use of the jclouds framework.  Examples will include using Whirr to manage hadoop and zookeeper clusters in java,  and pallet to build and manage application stacks including components as couchdb, tomcat, and nginx.. using clojure!

Experiences from building an extension framework

Adding the possibility to build extensions to an existing product has its own challenges. It has to be done without disrupting the product but at the same time exposing enough of the existing potential to be worthwhile for customers and partners to invest in learning it. QlikView has existed as a product since 1995 and reached version 10 some weeks ago. In this session we will present lessons learned while developing the first release of a extensions framework.

The Counterintuitive Web

The Web doesn't care for your finely-honed application architecture principles - for your orthodox tell-don't-ask, information hiding dictums, separated concerns, and guaranteed and reliable delivery strategies. It's an irresponsible place, where exposing your data, polling for results and making your errors the client's problem are considered acceptable behaviour. But despite all this, it consistently beats our enterprise application efforts-and all at massive scale

Rails 2.3, 3.0 and 3.1: Past, Present e Future

In late 2008, the two biggest frameworks existing in the Ruby community (Rails & Merb) decided to merge and announced the beginning of a series of efforts from where would emerge Rails 3.0.  Since the announcement, the community was surrounded by questions about how the future would look like. Will Rails change its philosophy? Which concepts will Merb bring to Rails?

Now, almost two years later, Rails 3 is out and rocking solid.

Pragmatic Interoperability: Making Java and .NET play well together

In this talk, learn how the two environments can interoperate with one another, not only over web services, but also via in-process channels and other methods. Along the way, we'll talk about how to leverage the strengths of each, such as using MS Office to act as a "rich client" to a Java middle-tier service, or building a Windows Presentation Foundation GUI on top of Java POJOs, or even how to execute Java Enterprise/J2EE functionality from within a Windows Workflow host.
