Ruby.NET 0.8 release
While IronRuby will make its debut in late July 2007, another Ruby implementation for .NET has been available for a year: the Gardens Point Ruby.NET compiler. The project has an interesting relationship with IronRuby - it provides its parser. Its latest release adds improved interoperability with other .NET languages.

JRuby Team members doubtful about IronRuby
Two members of the JRuby core team, Ola Bini and Charles O. Nutter, wonder whether Microsoft's IronRuby could possibly be a fully compliant Ruby implementation and run Rails, given Microsoft's policies. A viable alternative to IronRuby, the Ruby.NET compiler, is suggested.

Evan Phoenix hired to work on Rubinius
Evan Phoenix, who created Rubinius, a Ruby VM written in Ruby, has been hired by EngineYard. He'll work on Rubinius half time. This means that all Ruby implementations (Ruby, JRuby, IronRuby, Rubinius) now have paid developers working on them.

Google SoC Series: Creating RSpec specs for Ruby runtimes
The number of Ruby implementations grows steadily, but something is missing: a Ruby specification. The behavior of the Ruby language and its standard libraries is defined in the code of the main Ruby implementation. Two Google SoC projects aim to fix this by creating executable RSpec specifications for Ruby. We caught up with Pedro Del Gallego who works on one of these projects.

Microsoft Surpasses Java's Dynamic Language Support?
Microsoft's announcement of the Dynamic Language Runtime (DLR) has caused quite a stir in many areas, also in the Java space. Many voices seem convinced that the DLR has given .NET a major head start over the JVM, because it solves many problems Java is only just starting to realize. We look at the current situation of dynamic language support and how it compares to the DLR.

Introducing Visual Basic 10
With VB 9 slated to be released sometime this year, Microsoft is already talking about VB 10, also known as VBx. Key features include dynamic code generation like that you would expect in Lisp, Ruby, or Python. This opens up VB.Net for both Silverlight and Office.

Dynamic Language Runtime Announced
Microsoft has announced that they are building an extension to the Common Language Runtime called the Dynamic Language Runtime (DLR). This extension is being designed to enable interoperability between dynamic languages in the same manner that the CLR enabled interoperability between statically typed languages.

Microsoft announces IronRuby
Microsoft has just announced IronRuby at their MIX 07 conference. This also kicks off a bigger effort to support dynamic languages on .NET. Based on the experience gained in developing IronPython, a common Dynamic Language Runtime (DLR) builds the foundation for IronRuby, IronPython, JavaScript (EcmaScript 3.0) and Visual Basic.

Google SoC Series: ANTLR v3 Ruby Parser
Writing a Ruby parser is a challenging task, yet the XRuby team wrote one from scratch. A Google Summer of Code project will update the current parser to use ANTLR v3, and plans to produce a Ruby parser in Ruby in the process. InfoQ caught up with Wang Haofei to ask about the problems in parsing Ruby and the plans for the project.

.NET Memory Leaks
A problem with .NET that isn't talked about is the problems caused by using dynamic code generation. In a nut shell, dynamic code generation, which is used in XML Serialization, Regular Expressions, and XSLT transformations, can lead to memory leaks.

Strong Duck Typing Cut from VB 9
Visual Basic's implementation for duck typing, known as Dynamic Interfaces, has been cut from the Orcas release due to time constraints.
