A Look at Practical Platform-as-a-Service Architecture for Java and PHP Apps
In this session we will examine real examples of applications that have recently been ported to the Microsoft PaaS offering (Windows Azure) including how it was done. We will discuss the architectural principles, do’s and don’ts and examine what true scaling means from a developer point of view including database scalability, file I/O, session state management and more.

Seph
by Ola Bini
Seph is a new experimental language. It is based on pure differential prototype based object orientation, with immutability and polymorphic dispatch built in deep. Seph uses the new features in Java 7 to full effect, by compiling highly dynamic code to use method handles and invoke dynamic. It's got light weight threads and the mature concurrency primitives from Clojure.

The Kotlin Programming Language
The main design goals behind this project are
- to create a Java-compatible language,
- make it compile as fast as Java,
- make it safer than Java, i.e. statically check for common pitfalls such as null pointer dereference,
- make it more concise than Java by supporting local type-inference, first-class functions (closures), extension functions, mixins and first-class delegation, etc;
- and, keeping the useful level of expressiveness (see above), make it way simpler than the most mature competitor—Scala.
The compiler is being developed alongside with an IntelliJ IDEA integration, so the users will get IDE support as soon as they get the compiler (first public version is planned for the end of 2011).
Why yet another language?
Evolution of Java is problematic due to legacy issues (e.g., closures are being postponed over and over again), so the community is looking for more state-of-the-art alternatives.

Lessons from the Java.net Migration: Managing an Open Source Community through Major Change
by Sonya Barry
People hate change, and Java.net, a java-centric open source forge and community, needed a lot of change. Not just a facelift, but a whole new infrastructure with new development tools and a modern content management system. With 5600 projects and 600,000 registered members, and a handful of engineers dedicated to the task, how do you move a community this big without destroying it?
