Because of high demand, and many open questions, I will give an additional talk about GreenFire, the Audience Award Winner and 4th prize JAX Innovation Award:
Why it is easy to save energy?
Why Groovy is cool? (actually hot in the context of GreenFire :-))
How GreenFire saves energy.
Is my heating Java-enabled?
Heating and JavaFX.
Why SunSPOTs are useful?
Can you heating speak:-)?
Clustering Technology (Shoal) in a heating system.
Why a washmachine cable was sacrificied.
Why mocking leads to >65000 degrees Celsius.
...and why Ruby On Rails was too complex, and Java EE 5 (Glassfish) just right :-)
Next steps - and new ideas - and Enter The Matrix
After a short introduction to the domain of heating systems :-), I will try to answer this and your questions as well in the BOF / Session (Thursday: 24.04.2008): in Saal 12 BC, 15:15 - 16:15.
