Clojure has the most radical approach to concurrency of all the Java.next languages. This installment delves into some of the many facets of concurrency in Clojure, including the epochal time model and software transactional memory.
Java 8 incorporates new language features and added classes that give you easier ways to construct programs, including concurrent programs. Learn about new, powerful parallel-processing support in the language made possible by Java 8 extensions, including CompletableFuture and streams. You'll recognize similarities between these new features and some of the Scala capabilities that you explored in the first article of this series.
Java 8 incorporates important new language features that give you easier
ways to construct programs. Lamba expressions define a new syntax for inline
code blocks that gives you the same flexibility as anonymous inner classes,
with much less boilerplate. Interface changes make it possible to add to
existing interfaces without breaking compatibility with existing code. Learn
how these changes work together.
Perhaps the starkest difference among the Java.next languages lies in threading, concurrency, and parallelism. This installment shows easy ways to make existing functional code in Scala, Groovy, and Clojure parallel. Then it investigates the actor currency model in Scala.
The Java platform provides excellent support for concurrent programming in all JVM-based languages. Scala extends the concurrency support in the Java language with even more ways to share work among processors and coordinate the results. This first article in a new series on JVM concurrency covers the state of the art in concurrent programming in Java 7 and introduces some of the Scala enhancements. The article also helps prepare the way for understanding concurrency features in Java 8.
BLU Acceleration provides data warehousing and analytics as a service on
Codename: BlueMix. Developers can develop and deploy a heavy-duty
analytic application using blazing-fast IBM BLU database technology offered in
the cloud. Learn how to develop a data mining application using the Weka
statistical analysis tool and leveraging the IBM BLU columnar database.
Combine DITADoclet and DITA API specialization to save time and still
produce quality API documentation directly from the Java source
Learn how to develop and deploy a Java PaaS web app on the
In this video demonstration, Jay Allen walks through a five-minute demo
to show you what you need to do (and what you don't have to do!) to deploy,
run, and delete an application on Codename BlueMix.
Both Scala and Clojure are functional languages, and Groovy includes many
functional features through libraries. This Java.next installment explores how memoization is implemented in the Java.next languages and how the combination of functional features leads to concise power.
Java Sockets over RDMA (JSOR) is a new communication
library in the IBM Java 7 SDK for Linux platforms. JSOR can improve
throughput and reduce latency for client-server applications in cloud
environments by exploiting RDMA-capable high-speed network adapters. Learn
about the technology underlying JSOR, find out how to use the library, and
compare JSOR performance with solutions based on other communication
The previous Java.next
installment ("The invasion of functional programming") compared and contrasted functional coding styles in Scala, Groovy, and Clojure. In this article, series author Neal Ford delves more deeply into the filter, map, and reduce functions in the Java.next languages. A series of short coding examples help you to sort out the somewhat confusing differences in how the three languages name these key functional constructs.

Responsive Web Design (RWD) ensures a seamless user experience
across multiple device types and form factors. For a truly adaptive and holistic site experience across
devices, a responsive portlet user interface is essential. In this article, we discuss some of the more common yet
complex portlet UIs and show how to use WebSphere Portal V220.127.116.11
to make them render seamlessly across devices, without having to maintain
multiple code bases for each device type.
Learn what Node.js is and how to get started using it in this brief introduction.
