Ruby Performance: Great Shootout Results And A Discovery About Binary MRI vs Source Compiled MRI
Antonio Cangiano has again benchmarked all Ruby VMs, MRI 1.8 and 1.9.1, REE, JRuby, Rubinius, IronRuby and MagLev. The results show the steady improvement of the performance of all VMs - and a few surprising lessons of how the performance of MRI can vary.

The Ioke JVM Language: The power of Lisp and Ruby with an intuitive syntax
Ola Bini, a core JRuby developer and author of the book Practical JRuby on Rails Projects, has been developing a new language for the JVM called Ioke. This strongly typed, extremely dynamic, prototype based object oriented language aims to give developers the same kind of power they get with Lisp and Ruby, combined with a nice, small, regular syntax.

Ruby VM Roundup: Ruby 1.9.1 Preview 1, Rubinius Moves To C++ VM
Ruby 1.9.1 Preview 1 is now out, which marks a freeze on language features and most other items, with a final release of 1.9.1 scheduled for late January 2009. Ruby 1.9.1 is planned to be the first stable 1.9.x release. Also: the C++ branch of Rubinius has been promoted as the default branch.

LLVM and Ruby Roundup: llvmruby, yarv2llvm and regexpllvm, Rubinius
The llvmruby project provides Ruby bindings for LLVM. Yarv2llvm is a project built with llvmruby which translates Ruby 1.9 opcodes to LLVM bitcode, which can be compiled down to native code, using LLVM's JIT functionality. Also: the Rubinius VM, currently rewritten using C++, now also comes with LLVM.

More Languages on top of Erlang Virtual Machine
Erlang virtual machine – BEAM – hosts an increasing number of languages. Reia, a Python/Ruby like scripting language and Lisp Flavoured Erlang have recently been released. Debasish Ghosh reflects on this trend while other authors try to outline other possible language variants inspired by Ruby or Haskell.

Interview: Neal Ford On Programming Languages and Platforms
In this interview made by Sadek Drobi during QCon San Francisco 2007, Neal Ford talks about the tendency of having multiple languages running on one of the two major platforms existing today: Java and .NET. He also presents the advantages offered by Ruby compared to static languages like Java or C#.

Terracotta-VisualVM Integration Offers Cluster-wide Visualization and Event Correlation
Terracotta integration with Sun Microsystem's VisualVM tool offers JVM and cluster-wide visualization. Terracotta announced last week its integration with Sun's VisualVM technology which gives Java developers and web administrators visualization and analysis capabilities to assist in tuning and troubleshooting of Java applications using the Terracotta management console.

Article: Exploring LISP on the JVM
This article, written by Per Jacobsson, is aimed at Java developers curious about Lisp. It discusses the different dialects of Lisp that are available on the JVM today, and gives a crash course in how Lisp programming works and what makes it unique. Finally it looks at how Lisp code can be integrated with a Java system.

Article: Do Java 6 threading optimizations actually work? - Part II
In part 2 of "Java 6 threading optimizations" article series, author Jeroen Borgers examines various threading optimizations and JVM arguments to manage them. He also talks about factors like On Stack Replacement (OSR), Heap Management and Lock object data size which could significantly affect the performance of multi-threaded java applications.

Excelsior JET 6.4: Smaller, Faster, More Secure Java
Since the beginning of time Java applications have been battered with complaints about startup time, memory footprint, performance and security. Recently Sun started to address some of the issues by introducing the Consumer JRE. However, Excelsior JET is a product which provides their own spin on solving these problems.

Article: Do Java 6 threading optimizations actually work?
Features like biased locking, lock coarsening, lock elision by escape analysis and adaptive spin locking are all designed to increase concurrency by allowing more effective sharing amongst application threads. But do they actually work? In this two part article, Jeroen Borgers explores these features and attempt to answer the performance question with the aid of a single threaded benchmark.
