Avi Bryant on DabbleDB, Smalltalk and Persistence
In this interview, Avi Bryant talks about the Smalltalk web framework Seaside, DabbleDB, using Smalltalk images for persistence instead of an RDBMs, GemStone and more.

A growing number of fully fledged software stacks for Ruby is available, providing all the necessary software you need to run an application, including web and database servers. They come in different flavors: virtual machine images, Amazon EC2 images and installer based. We take a look at some of them to give you an overview.
Some recent changes on the JRuby trunk improve Java Integration, which allows JRuby to interact with pure Java code faster and more conveniently. Also: Ruby code compiled with JRuby's (JIT) compiler can now make use of the JVMs debugging capabilities using JSR-45 (Debugging Support for Other Languages).
A few security vulnerabilities were discovered in Ruby 1.8.5 to 1.8.7 and 1.9.x. The vulnerabilities are found with safe levels, WEBrick has a DoS vulnerability in a particular regular expression, shared library API dl doesn't check taintedness and resolv.rb has a problem with DNS spoofing.

A misconception lingers in the Ruby world: Ruby has no debugger. This is blatantly wrong - Ruby has debuggers, GUIs for debuggers and APIs for debuggers. InfoQ takes a close look at the state of debugging tools in the Ruby world - and finds that its debugging support is more than sufficient.

In this interview, Avi Bryant talks about working on GemStone's MagLev, a Ruby implementation built on the GemStone S64 VM. Avi explains the reasons for MagLev, the merits of GemStone's persistence and distribution features, and the future with multiple Ruby implementations.

Evan Phoenix discusses Rubinius, a modern Ruby VM loosely based on the Smalltalk-80 architecture. The goal is to build a fast, efficient VM with the latest research in dynamic language implementations

In this presentation from QCon San Francisco 2007, Adrian Colyer describes the OSGi specification, OSGi implementations, modularity, versioning, operational control, server-side OSGi, design considerations, using existing libraries, Spring Dynamic Modules, and writing a Spring Dynamic Modules application.

In this presentation from QCon San Francisco 2007, Chet Haase discusses Java SE 6, Update N/Consumer JRE, the goals and feature set for Java FX (e.g. media support, scene graph, HTML and mobile devices), and the current set of possible features for JDK 7 such as Java FX features, Swing-related JSRs (295 and 296), transparent/shaped windows, tiered compilation, closures and invoke-dynamic bytecode.
