Vaughn Vernon, author of Implementing Domain-Driven Design, recently talked about using Scala and the Actor Model implementation Akka together with Doman-Driven Design as a means to remove some of the architecture overhead typically found in event-driven or hexagonal architectures.
Oracle have released videos and slides from the 2013 JVM Language Summit, which saw uses of the JVM from the biggest data to the smallest mobiles, and future performance advances in the JVM runtime. Read on to find out more about what was covered.
core.typed adds an optional type system to Clojure, aiming to combine the best of both worlds: the brevity and flexibility of Clojure and the safety guarantees that a type-checker provides.
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.
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.
InfoQ's research initiative continues with an 12th question: "What's Your Next JVM Language?". This is a new service we hope will provide you with up-to-date & bias-free community-based insight into trends & behaviors that affect enterprise software development. Unlike traditional vendor/analyst-based research, our research is based on answers provided by YOU.
Twitter's infamous Fail Whale was absent on US presidential election day, even as Twitter's servers were handling a serge of 327,452 "tweets" per minute. The firm was able to handle this level of traffic thanks in part to a gradual shift away from Ruby to Java and Scala
Atmosphere 1.0 is a new Java/Scala/Groovy framework that attempts to abstract asynchronous communication between the web browser and the application server. It transparently supports Web Sockets, HTML5 Server Side events and other application server specific solutions when available, with long polling as a fallback.
InfoQ's research initiative continues with an 11th question: "Why Are You Not Using Functional Languages?". This is a new service we hope will provide you with up-to-date & bias-free community-based insight into trends & behaviors that affect enterprise software development. Unlike traditional vendor/analyst-based research, our research is based on answers provided by YOU.
InfoQ's research initiative continues with an 10th question: "Top 20 Web Frameworks for the JVM". This is a new service we hope will provide you with up-to-date & bias-free community-based insight into trends & behaviors that affect enterprise software development. Unlike traditional vendor/analyst-based research, our research is based on answers provided by YOU.
The team behind Scala is adding an experimental version of macros in the forthcoming release version 2.10. Scala macros provide an advanced form of compile-time meta-programming.
Gradle 1.0, a build system powered by a Groovy DSL, has been released. Gradle is compatible with Ant tasks, Maven repositories, and has support for the popular IDEs. It attempts to find the sweet spot between the flexibility of Ant and convention-over-configuration of Maven.
