After active annotations were introduced in Xtend 2.4, they received an API for accessing the file system with version 2.4.3. Active annotations let developers influence the way, Xtend source code is translated to Java source code. With the help of the new file system API, further artifacts like property files or fingerprints and digests can be derived from Xtend sources.
Reactive programming (RP) is based on data flows and the propagation of change, with the underlying execution model of a programming language automatically propagating changes through the data flow. With the popularity of event-driven, scalable, and interactive architectures both on the server and the client, the concept of “reactiveness” is increasingly gaining attention.
For many of us Twitter has become an essential communications utility. Since experiencing scalability problems in 2010, Twitter has moved to a loosely coupled service oriented architecture based on the JVM, allowing it new levels of scalability and feature agility. Twitter engineering recently reported a new record throughput and took time out to describe their new architecture.
Oracle has reversed their decision to remove the method sun.reflect.Reflection.getCallerClass(int) in Java 7u40. The method is planned to remain at least through Java 7.
In recent years, new trends like mobile clients and social networks forced web applications to handle more and more concurrent connections. This resulted in new server architectures based on eventing and asynchronicity which you can find for example in Vert.x. Tim Fox told InfoQ what's new in version 2.0 of Vert.x.
While it has been less than a month since the announcement of the core.async Clojure/ClojureScript library, a number of blog posts have been published describing how to use it effectively to avoid "callback hell" in front-end code, and showing off simple code resulting in some impressive demos.
During QCon New York 2013, Rich Hickey gave a talk on functional databases. Hickey is well known for creating the Clojure programming language and is currently developing Datomic, which is a functional database. During his talk, Hickey argued that the useful properties of functional languages: data as values and pure functions, are just as useful in the context of databases.
The investigating agency Kaspersky Labs uncovered in mid January that the Red October attackers used the Rhino exploit in Java as an additional delivery vector.
VMware's SpringSource team have recently announced plans for Spring 4.0, the next update to the framework, with new features including support for Java SE 8, Groovy 2, parts of Java EE 7, and WebSockets. InfoQ spoke to Spring framework co-founder Juergen Hoeller to find out more about the plans.
ZeroTurnaround, the vendor behind the popular JRebel and LiveRebel JVM plugins, which accelerate the Java development cycle and automate app deployments to live environments without downtime, have announced a new research and content organisation called Rebel Labs. The organisation will, they claim, offer free, vendor-neutral technical resources for the Java community.
JetBrains has announced IntelliJ IDEA 12 having a better compiler, support for Java 8, an Android UI Designer, a new look, better Spring and Play 2.0 support, and a large number of enhancements across supported languages and frameworks.
Cloud Foundry Core is a web application that verifies public instances (Cloud Foundry Endpoints) against a common set of runtimes and services. This helps portability across companies that provide Cloud Foundry instances. At the same time a new version Micro Cloud Foundry is released with support for Java 7.0, JRuby, Play 2.0 framework and more.
