Attila Szegedi talks about performance tuning Java and Scala programs at Twitter: how to approach GC problems, the importance of asynchronous I/O, when to use MySQL/Cassandra/Redis, and much more.
Dyn.js is a new implementation of Javascript for Java. It makes use of Java 7's new features for dynamic languages (invokedynamic, Method Handles). InfoQ talked to dyn.js creator Douglas Campos about the reasons to create another Javascript for the JVM (next to Rhino and the announced Oracle Nashorn) and implementation details of dyn.js.
Charles Nutter of JRuby fame recently started assisting the Rhino project (Java implementation of JavaScript) to speed up the Rhino JavaScript runtime.
AppengineJS is an open source JavaScript port of the Google App Engine Python SDK helpful to create web applications that can be deployed on GAE infrastructure accessing Google’s persistent storage and services.
Dion Almaer has published a podcast of his interview with Steve Yegge, the creator of Rhino on Rails. Rhino on Rails is a Javascript port of the popular Ruby on Rails framework.

The latest version of the very popular mocking framework, Rhino Mocks version 3.3 is complete and ready to be used by your tests. This release provides many new features including Remoting Proxies and more.
Oren Eini talks about the difficulty to build N-tiered systems that are highly scalable, presenting several concepts – divide and conquer, background evaluation, one way messaging, the single responsibility principle - along with .NET frameworks – NServiceBus, Rhino ESB, Mass Transit, Rhino PHT, Rhino DHT, Raven DB - which help solving the scalability problem.
In this presentation from the JVM Languages Summit 2008, Cliff Click discusses how to optimize generated bytecode for running on the JVM. Click analyzes and reports on Java, Scala, Clojure, JRuby, JPC and JavaScript/Rhino and points out several places where each of them could increase their performance such as elimination of FixNums, escape analysis and best practices for testing bytecode.
Attila Szegedi discusses the Rhino JavaScript engine. Topics covered include the implementation of Rhino, Rhino's featureset, continuations, usage patterns for embedding Rhino, running JavaScript on the server, scripting capabilities for Rhino, JavaScript versus Ruby, JavaScript on Rails, and future plans for Rhino.
