Time for the “Best Of The Week” links for the week that just passed. Here are some links that drew Java Code Geeks attention:
* The 10 commandments of good source control management: An amazing collection of source control management best practices, don’t miss it. The examples are for .NET and Subversion, but the principles described are totally generic. Also check out Git Tutorial – Getting Started and Git DVCS – Getting started.
* Spring Data – Part 5: Neo4j: This tutorial shows how to get started with Neo4j (install and run a standalone Neo4j server instance) and how to configure a Maven based Spring Data Neo4j project for high-level manipulation of Neo4j graphs. Also see Domain modeling with Spring Data Neo4j and The Persistence Layer with Spring Data JPA.
* Hibernate 4.1 Released With Improved Auditing Support: JBoss has released version 4.1 of Hibernate which includes several fixes and improvements. There is also a very interesting new feature in the audit module of Hibernate (previously known as Envers), having an additional history table for each audited Entity.
* Cloud Computing Basics: the CAP Theorem: An introduction to CAP theorem (Consistency, Availability and Partition Tolerance) and how that applies to Cloud computing. The theorem states that a distributed system can satisfy any two of these guarantees at the same time, but not all three.
* Communicate Business Value to Your Stakeholders: This article states that stakeholders in an organization need to understand what it is you will do for them in a language that creates meaning for them and suggests that this can be achieved by communicating in terms of benefits, not features.
* From Java code to Java heap: This article provides insight into the memory usage of Java code, covering the memory overhead of putting an int value into an Integer object, the cost of object delegation, and the memory efficiency of the different collection types. Additionally, it shows how inefficiencies occur in your application and how to choose the right collections to improve your code.
* Developer Productivity Report – Part 4: Deployment Pipeline: This research shows that most Production Update processes are done manually, something that was a bit expected (sadly). More specifically, the majority of those surveyed said that their processes for deploying applications to the production environment are generally not automated to any significant degree.
* VMware Introduces Spring Hadoop: VMware have announced the availability of Spring Hadoop, which integrates Spring and Hadoop. The project provides a convenient mechanism for the configuration, creation, and execution of various services and utilities such as MapReduce, Hive, Pig, and Cascading jobs via the Spring container. Also see Big Data analytics with Hive and iReport.
* Integration of a transaction manager in Tomcat for Spring and OpenJPA: This tutorial shows how to add a JTA transaction manager to Tomcat where a web application should be deployable on a full fledged application server without modification. The open source version of the Atomikos transaction manager was used. Also see GWT Spring and Hibernate enter the world of Data Grids.
* Spring 3.1 and MVC Testing Support: In this presentation the TestContext Framework is introduced and is shown how to use @Configuration and environment profiles for testing with Spring 3.1, and the testing support available in Spring MVC. Also see Spring MVC Development – Quick Tutorial and Spring Pitfalls: Transactional tests considered harmful.
That’s all for this week. Stay tuned for more, here at Java Code Geeks.
Cheers,
