"Some aspects of system implementation, such as logging, error handling, standards enforcement and feature variations are notoriously difficult to implement in a modular way. The result is that code is tangled across a system and leads to quality, productivity and maintenance problems. Aspect Oriented Software Development enables the clean modularization of these crosscutting concerns. The AspectJ Development Tools (AJDT) project provides Eclipse platform based tool support for AOSD with AspectJ. Our goal is to deliver a user experience that is consistent with the Java Development Tools (JDT) when working with AspectJ projects and resources. "

"A better way to build. Project automation is essential to the success of software projects. It should be straight-forward, easy and fun to implement. There is no one-size-fits-all process for builds. Therefore Gradle does not impose a rigid process over people. Yet we think finding and describing YOUR process is very important. And so, Gradle has the very best support for describing it. We don't believe in tools that save people from themselves. Gradle gives you all the freedom you need. Using Gradle you can create declarative, maintainable, concise and highly-performing builds. "

In this article I'll describe the setup I use to do develop Lift applications. While more heavy-weight than if an interpreted language is used, I find this setup provides fairly decent turnaround times. So, it took a little longer than expected to write this article which continues where the previous stopped. But all good things come to he who waits The software used in the previous article all had major updates in the meantime: Scala 2.8 (2.8.1 is just around the corner) Eclipse 3.6 Scale IDE for Eclipse (though a nightly build is currently needed for Eclipse 3.6) Gradle 0.9 RC1 Lift 2.1 RC2

There was a recent outburst in blogs on the topic of Groovy and how it compares to Java. Although I respect the youthfull entusiasim of Groovy and Co. working on this little exercise I'm just perplexed by the "WHY?" in this whole discussion. Let me just say again: W H Y ?!?! 1. Practically no one cares about Groovy (let alone Groovy++ strap-on) beyond Grails community. So this language just as "widely accepted" as Ruby (at least for enterprise software development) 2. If you know Java it's equally "challenging" to pick up either Groovy or Scala. Don't let anyone insult your intelligence by claiming that Scala syntax is somehow more complex than Groovy. In both languages you will need to adapt to functional thinking - and that's where you will have to spend a couple of weekends… 3. If you know Groovy - you already know 90% of Scala (different syntax and few extra features can be picked up in the evening) 4. Scala is designed by people who have proper academic background, experience and talent in the area of language design - Groovy has never been that way (and anyone who dares to look inside of Groovy runtime or history of changes in it will attest to that). NOTE: it did come out rather strong - but that's how I feel about it and after some thinking I'll leave as is. Nothing personal to anyone reading it… 5. Scala as a post-functional language is years ahead of Groovy (static typing with best-in-business type inference, highly tuned mix of imperative and functional styles, powerful and done-right generics, etc.) 6. Groovy will ALWAYS be slower than Scala or Java (latest benchmarks put even Groovy++ about 50 times slower than Java) just by its nature unless someone changes the language and rebuilds the runtime from the ground up. 7. Once we get decent integration with Eclipse, NetBeans and IDEA for Scala, the Groovy will lose its only serious advantage

Legacy systems embrace a large number of technologies, making the development of tools to cope with legacy systems evolution a tedious and time consuming task. As modernization projects face with both technologies combination and various modernization situations, model-driven approaches and tools offer the requisite abstraction level to build up mature and flexible modernization solutions. MoDisco provides an extensible framework to develop model-driven tools to support use-cases of existing software modernization :

"How much can the IDE predict what you will write in the next seconds? "Code Recommenders" is a blog about ongoing research projects developing so called Framework Understanding Tools (FrUiTs for short) - or more general recommender systems that help developers to deal with the complexity of today's software development. It has a strong focus on new Eclipse based tools and discusses/presents ideas how to overcome issues with current IDEs."

There are many approaches available to scale PostgreSQL beyond running on a single server. An outline of the terminology and basic technologies involved is at High Availability and Load Balancing. There is a presentation covering some of these solutions. There is no one-size fits all replication software. You have to understand your requirements and how various approaches fit into that. For example, here are two extremes in the replication problem space: You have a few servers connected to a local network you want to always keep current for failover and load-balancing purposes. Here you would be considering solutions that are synchronous, eager, and therefore conflict-free. Your users take a local copy of the database with them on laptops when they leave the office, make changes while they are away, and need to merge those with the main database when they return. Here you'd want an asynchronous, lazy replication approach, and will be forced to consider how to handle conflicts in cases where the same record has been modified both on the master server and on a local copy. These are both database replication problems, but the best way to solve them is very different. And as you can see from these examples, replication has a lot of specific terminology that you'll have to understand to figure out what class of solution makes sense for your requirements. A great source for this background is in the Postgres-R Terms and Definitions for Database Replication. The main theoretical topic it doesn't mention is how to resolve conflict resolution in lazy replication cases like the laptop situation, which involves voting and similar schemes.

"I'm with Politecnico di Milano, Italy, researching on the application of model driven development (MDE/MDD/MDA = MD*) techniques to all the software field, including: web engineering and modeling of web applications (WebML, WebRatio), multimedia & multidomain search engines (Search Computing), business processes (BPMN), and web services."

Akka is the platform for the next generation event-driven, scalable and fault-tolerant architectures on the JVM We believe that writing correct concurrent, fault-tolerant and scalable applications is too hard. Most of the time it's because we are using the wrong tools and the wrong level of abstraction. Akka is here to change that. Using the Actor Model together with Software Transactional Memory we raise the abstraction level and provide a better platform to build correct concurrent and scalable applications. For fault-tolerance we adopt the "Let it crash" / "Embrace failure" model which have been used with great success in the telecom industry to build applications that self-heal, systems that never stop. Actors also provides the abstraction for transparent distribution and the basis for truly scalable and fault-tolerant applications. Akka is Open Source and available under the Apache 2 License.

"Quercus is Caucho Technology's 100% Java implementation of PHP 5 released under the Open Source GPL license. Quercus comes with many PHP modules and extensions like PDF, PDO, MySQL, and JSON. Quercus allows for tight integration of Java services with PHP scripts, so using PHP with JMS or Grails is a quick and painless endeavor. With Quercus, PHP applications automatically take advantage of Java application server features just as connection pooling and clustered sessions. Quercus implements PHP 5 and a growing list of PHP extensions including APC, iconv, GD, gettext, JSON, MySQL, Oracle, PDF, and Postgres. Many popular PHP application will run as well as, if not better, than the standard PHP interpreter straight out of the box. The growing list of PHP software certified running on Quercus includes DokuWiki, Drupal, Gallery2, Joomla, Mambo, Mantis, MediaWiki, Phorum, phpBB, phpMyAdmin, PHP-Nuke, Wordpress and XOOPS. Quercus presents a new mixed Java/PHP approach to web applications and services where Java and PHP tightly integrate with each other. PHP applications can choose to use Java libraries and technologies like JMS, EJB, SOA frameworks, Hibernate, and Spring. This revolutionary capability is made possible because 1) PHP code is interpreted/compiled into Java and 2) Quercus and its libraries are written entirely in Java. This architecture allows PHP applications and Java libraries to talk directly with one another at the program level. To facilitate this new Java/PHP architecture, Quercus provides and API and interface to expose Java libraries to PHP. The Quercus .war file can be run on Java application servers such as Glassfish, i.e. it can be run outside of Resin. This .war file includes the Quercus interpreter and the PHP libraries."

"Clojure is a dynamic programming language that targets the Java Virtual Machine (and the CLR ). It is designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. Clojure is a compiled language - it compiles directly to JVM bytecode, yet remains completely dynamic. Every feature supported by Clojure is supported at runtime. Clojure provides easy access to the Java frameworks, with optional type hints and type inference, to ensure that calls to Java can avoid reflection. Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy and a powerful macro system. Clojure is predominantly a functional programming language, and features a rich set of immutable, persistent data structures. When mutable state is needed, Clojure offers a software transactional memory system and reactive Agent system that ensure clean, correct, multithreaded designs. I hope you find Clojure's combination of facilities elegant, powerful, practical and fun to use."
