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.

Dan Diephouse on SOA governance with Mule Galaxy
Released in January 2008 
, Mule Galaxy is an open-source, REST-based SOA governance platform that sidesteps the UDDI standard in favor of ATOM. Positioned
as the everyman's SOA registry and repository, Mule Galaxy represents a major shift in SOA, toward a more lightweight, open-source
approach to service-oriented development. In this talk with Andrew Glover, Galaxy's chief architect Dan Diephouse talks about
his own move away from Web services (after creating the XFire project) and Galaxy's RESTful approach to service-oriented architecture.

Brian Sletten on REST done right
Brian Sletten
is a regular speaker on the No Fluff Just Stuff tour and an established expert on REST and RESTful Web application development.
In this talk with Andy Glover, Brian demystifies REST as an application protocol, not a transport protocol, and describes
the series of interactions that define REST. As he explains, REST is best used for managing information and information spaces
without revealing back-end implementation. What it is not about, he says, is hijacking the GET verb and abusing it badly.

Ted Neward on why Java developers need Scala
Scala often gets lumped in with dynamic languages like Groovy and Jython, but
in fact it is a very different creature -- a statically typed functional-object hybrid language written for the JVM. In
this talk with Andrew Glover, Ted Neward explains the difference between functional and object-oriented languages and what
you can naturally do with them. He then discusses some important domains where Java and other purely OO languages simply are
not a good fit, including concurrency and database programming -- both areas where Scala really shines. You'll also learn
about lift and some of the highlights of Scala syntax, in this discussion with the author of "The busy Java developer's guide
to Scala."

Ken Russell on making applets FAST
As lead architect of the next-generation Java Plug-in, Ken Russell
is passionate and convincing on the topic of client-side Java development and the return of the applet. In this interview
with Andrew Glover, Ken offers an engineer's perspective on the historic problems of applets. He then explains how the new
Java Plug-in has been re-written to run on a separate process from the Web browser, enabling applets to start fast, consume
the memory they need, and run without stopping or freezing the browser.

Scott Davis on GIS beyond Google Maps
When Scott Davis isn't editing AboutGroovy.com you'll find him on the No Fluff Just Stuff tour, where he is known as both
the Groovy guy and the Google Maps guy. 
Here he talks with Andrew Glover about what Google Maps has done to make geomatics, or geographic information systems, more
accessible to your average Web developer. He also discusses in-depth the options available for Java developers who require
a more sophisticated, less closed-stack GIS solution than Google Maps provides. This is an informal primer from a leading
authority on using geospatial data, Web services, and open source APIs in Java Web development.

Sebastien Arbogast on OSGi and Java modularity
Like many Java developers, Sebastien Arbogast only recently realized OSGi's tremendous potential for bringing modularity to
the Java platform. Since then he has become an OSGi enthusiast and founded 
DZone's OSGi zone. In this discussion with Andrew Glover, Sebastien succinctly introduces OSGi and explains why its contribution
to Java modularity is such good news for Java developers on the server side. He also discusses the competing Java modules
specifications (JSR 291 and JSR 277), talks about the app-server migration to OSGi, and makes a tentative prediction about
what might be coming next for this exciting technology.

Bill Venners on the rise of Scala
Scala is a scalable language that blends functional and imperative programming styles in an 
object-oriented framework familiar to Java developers. In this discussion with Daniel Steinberg, Bill Venners explains why
some experienced Java programmers are unwilling to give up static-type checking, even for the productivity benefits found
in dynamic languages like Ruby and Python. He also delves into the particulars of programming with Scala, like what makes
it so scalable, how it supports code quality, and where it best fits into your Java development toolkit. Take this opportunity
to learn from a master about what's under the hood with Scala. You'll also gain deeper insight into why functional programming
is moving from margins to center for many Java developers, and why dynamic languages should not be your only functional programming
alternative.
