Java Performance and L2 cache

It surprises me how many times Java Performance is considered to be linear proportional to the clock frequency of the CPU, thereby ignoring all other parameters.

Communication between websites

The number of dynamic websites is exploding. But also, the definition of "dynamic" is exploding. We are not talking about updating content, but rather about integrating content and services from different sources.

Integrating with Adobe Acrobat Connect

Recently, I got a trial account for Adobe Acrobat Connect Pro. Although I am impressed by the functionality of this product itself, I am mainly interested in how to connect with Adobe Connect, and how to integrate it with existing Java applications. It is rather easy to do so!

OpenSocial evolutions

At this moment, I am working on three projects that somehow are related to OpenSocial. This is not a coincidence.

GlassFish Roadmaps

The roadmaps for GlassFish v2.1 and v3 are available online. One of the consequences of Sun Microsystems making their application server an Open Source effort, is that we can see and learn from their release policies.

Using Knopflerfish Desktop in GlassFish v3

In a previous blog entry, I wrote about running GlassFish v3 on the KnopflerFish OSGi Framework. I spent some more time on this, in particular I managed to use the KnopflerFish Desktop bundle to inspect the GlassFish Bundles and Services.

OSGi Modularity in DaliCMS and GlassFish

If you are following my blog, you probably know that I am recently investigating the modularity of GlassFish v3 and see how it is using the OSGi technology. The main reason for this is that I see some similarities with DaliCMS, the open source "Web 2.0 ready Content Management" system we developed with LodgON and that runs on top of GlassFish.
