* QoS for Applications: A Resource Management Framework for Runtimes: A very interesting article that describes how we can use concepts used in the networking field in order to implement resources management in runtimes and containers. Using a similar framework we may be able to provide Quality of Service for applications all running in the same container.
* Parallel programming in Java: A small interview around the Ateji PX Java extensions, an extension of Java that makes parallel programming easier. Parallelism is expressed by simple composition operators and multiple models are supported.
* Functional thinking: Immutability: Immutability is one of the building blocks of functional programming.This great article explains how to implement immutability in Java and Groovy.
* The Principles of Good Programming: Title says it all. Among them are the Don’t Repeat Yourself principle, the Open/Closed, the Single Responsibility and others. Also check The top 9+7 things every programmer or architect should know and Things Every Programmer Should Know.
* Why is JBoss AS 7 so fast?: This article explains why JBoss AS 7 is so fast at startup. Except for the modular approach used, the reason is the effective parallelization of work based on Ahmdahl’s law.
