Jeroen Frijters: Multi Target Support

I've now enabled "multi target" support. This means that you can compile multiple
assemblies at once. One of the advantages this has is that it makes dealing with circular
dependencies much easier, but even if there aren't any circular dependencies, it can
make building much easier because you don't have to do any dependency analysis.

Rod Johnson: SpringSource and the future of Spring

The recently announced SpringSource Enterprise Maintenance Policy came as a surprise to many Java developers, in some circles sparking anger and calls for a Spring fork. One factor in the controversy may be the relationship between the lesser known commercial vendor, SpringSource, and its widely popular open source product, the Spring framework. In this discussion with Andrew Glover, SpringSource CEO Rod Johnson talks about how his company walks the line between commercial success and its driving role in open source projects such as the Spring framework and Tomcat. Similarly, he explains what factors might cause developers to migrate from Spring's strictly free and open source products to the commercial, and costly, SpringSource Enterprise package. Johnson also discusses the new, OSGi-based SpringSource Application Platform, which he says is designed not for where the Java enterprise market has been, but for where it is going.

Sharding with Max Ross - Hibernate Shards

Max Ross is the Google engineer who spends his days working on the Google App Engine data store. On the side he works on Hibernate Shards, another scalability-obsessed project that is open source. In this talk with Andrew Glover, Max explains sharding, which is the strategy of storing application data on multiple databases. As Max explains, sharding may not be popular but it is a necessary for some applications dealing with a high volume of data. In those cases, Hibernate Shards provides a unified view into any number of databases, making huge amounts of data manageable even as the system evolves.

Implement a Facebook photo album using the Flex SDK

Adobe has released the free, open source Flex SDK framework to enable developers
to create Rich Internet Applications (RIAs). The Flex framework provides you with
a method of creating cross-browser, cross-platform Web applications that is quick and
simple. Flex applications run in the Flash player, which is installed on the majority of
Internet-connected computers, but Flex provides you with an object-oriented
user interface framework similar to Java's Swing. In this tutorial, develop a
Facebook application in Adobe Flex that displays a slideshow of a user's Facebook
photo albums. The Facebook application will contain a Profile box listing all of the
user's photo albums, each a link to a Flex slideshow of that album. The Flex application
will use the Facebook REST API to fetch the photos of the selected Facebook album and
dynamically generate the slideshow.
