Patrick Curran on reforming the JCP
Recent controversies have eroded confidence in the Java Community Process 
and left some leaders in the developer community calling for reform. In this conversation with JCP Chair Patrick Curran,
Andrew Glover gets an overview of the structure and inner workings of the process. He learns first-hand where the JCP has
historically fallen apart and gets Curran's view on what can be done to reform it. While candid about Sun's ambivalent relationship
to open source, and about the predominance of corporate interests on the JCP Executive Committee, Curran ultimately places
responsibility for reform in the hands of developers. Anyone can join the JCP, he says, and participation is key to democracy.

Unwrapping JavaFX 1.0
JavaFX 1.0 makes its debut today amid high hopes and a sea of doubt. 
Some in the Java community believe JavaFX could become "the application environment for the Java platform," while others say
Sun has made nothing but mistakes on the client side, and JFX is too little, too late. In this talk with Sun Microsystems
Senior Director of Java Marketing Param Singh, and JavaFX Architect John Burkey, Andrew Glover addresses both the concerns
associated with JavaFX 1.0 and its potential. Get the developer's perspective on what you'll be able to do with JavaFX 1.0.

High scalability and Java with Todd Hoff
Todd Hoff's High Scalability Blog is a destination 
for developers tasked with building Web apps that scale. One of the blog's best features is its extensive list of site profiles,
which reveal the architectural decisions (and revisions) that support Web 2.0 success stories like Amazon, eBay, and Twitter.
In this podcast Andrew Glover picks Hoff's brain about scalability tactics like sharding, parallelization, and caching. The
two also discuss the challenge of building scalable Web sites that support cloud computing, or service-level architectures,
where traffic comes in over APIs. In the end, Hoff gives his insight into why Java isn't necessarily first choice for building
sites that scale big, and tips for what to do if you -- like LinkedIn and Fotolog -- decide to use Java anyway.

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.

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."

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.

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.

Neal Ford on what JRuby has that Java doesn't
Neal Ford and Andrew Glover are both well respected Java developers, as well as big fans of Ruby. 
In this in-depth discussion, Ford talks about why he believes Ruby is the most powerful language you could be paid to program
with today, and explains the particular benefits of programming with JRuby. Ford also reveals why he believes Java developers
will continue to migrate to languages other than Java, even as many continue to call the Java platform home. This is an essential,
engaging discussion for those interested in learning more about JRuby and the trend toward what Ford calls polyglot programming.
