Augmented reality (AR) is a term for a live direct or indirect view of a physical real-world environment whose elements are augmented by virtual computer-generated imagery. It is related to a more general concept called mediated reality in which a view of reality is modified (possibly even diminished rather than augmented) by a computer. As a result, the technology functions by enhancing one’s current perception of reality.

Attacking Waste in Software, Jean Tabaka

admin — Sun, 09 May 2010 04:48:58 +0000

One of the seven principles of Lean Thinking is “eliminate waste.” Eliminating waste means minimizing the cost of the resources we use to deliver software to our stakeholders. In this keynote presentation from the 2008 Better Software Conerence & EXPO, Jean Tabaka proposes three pivotal practices that we must embrace to aggressively attack waste in software delivery—Software as a Service, Community, and Fast Feature Throughput. When IT and all software organizations embrace these practices, they will eliminate waste within their organizations, reduce the waste that consumes our entire industry, and ultimately support the broad twenty-first century global mandate to manage our scarce resources.

As of version 2.0, JAX-RPC has been renamed JAX-WS. But the change is not in name alone. JAX-WS offers simplified development, better platform and language independence, and an end to the chaotic array of earlier Java Web services frameworks. This article explores the high-level architecture of JAX-WS, along with its low-level inner workings. It then walks you step by step through creating your first JAX-WS Web service.

Why Agile Teams Fail - Erik Doernenburg

gpuri — Sat, 08 May 2010 00:38:43 +0000

Agile methodologies such as eXtreme Programming and SCRUM are hot topics today — and they are also hot targets. When things go wrong on an agile project, it’s far too convenient to blame the methodology, and not the people charged with implementing it correctly. In this talk Erik discussed the most common reasons a team may fail when trying to execute a project using an agile methodology. He also covered how to learn from the mistakes of others, and avoid repeating new mistakes of your own. This talk is based on experiences Clinton Begin and Erik have had on projects at ThoughtWorks.

“The Clean Code Talks” - Inheritance, Polymorphism, & Testing

admin — Sun, 02 May 2010 17:01:19 +0000

Is your code full of if statements? Switch statements? Do you have the same switch statement in various places? When you make changes do you find yourself making the same change to the same if/switch in several places? Did you ever forget one?

This talk will discuss approaches to using Object Oriented techniques to remove many of those conditionals. The result is cleaner, tighter, better designed code that’s easier to test, understand and maintain.
