Java type inference won't support differentiation of mutable vs immutable variables due to lack of consensus within the community regarding how this should be implemented, recent communication shows. Also, to prevent a long debate about corner cases, a number of such cases will be ruled out. Although the JEP doesn't indicate a target version, Java 10 seems likely.
Javaslang, an open-source functional library that provides persistent data types and functional control structures for Java 8 and beyond, published a roadmap for a major release version 3.0 that promises significant changes to the library to remove unnecessary and deprecated features.
Lightbend surveyed over 2100 JVM developers to study correlations between development and infrastructure trends. Their findings, published in a whitepaper, revealed that microservices and lightweight containers are challenging heavyweight J2EE application servers.
Details of the new Scala Center, a non-profit organization created to focus on education and the open source community, were presented by research scientist Heather Miller during her June 16, 2016 keynote address at Scala Days Berlin.
JetBrains has released IntelliJ IDEA 2016.1, the latest version of their most popular IDE. The new version seems to have the polyglot developer in mind, with multiple enhancements over a variety of languages and technologies; however, the most noticeable changes are aimed at Java, particularly at helping developers take full advantage of Java 8.
Last week, the Scala Center was created as a not-for-profit foundation, along with a list of financial backers, to improve the ongoing development of Scala and provide training courses based around the Scala language.
The company formerly known as Typesafe, inventors of the Scala programming language, has completed their renaming and is now known as Lightbend. Typesafe announced their plans to rename last May, stating at that time that it was expected to be a two month process. They invited community members to participate, and provided blog updates about their progress.
JetBrains has released IntelliJ IDEA 15, with improved Java 8 lambda debugger support, a better user interface for running tests, enhanced JVM frameworks support (Spring 4.2, Hibernate 5.0, Grails 3.x, and Arquillian), TypeScript 1.6 and TSLint integration, and initial support for Angular 2.
Dotty, a platform aimed to develop new technology for Scala tooling as well as try out new concepts for future Scala versions, has reached bootstrap status. This means that its compiler is written in Dotty and can compile itself, thus providing a drop-in replacement for the original one. InfoQ has spoken with Dotty major contributor Dmitry Petrashko.
Bazel, the build system that Google open sourced six months ago, has reached the first beta milestone as planned, adding support for several languages and technologies.
Typesafe's Play team has released version 2.4 "Damiya" of their web framework. By embracing dependency injection, the refactoring towards better modularization that was started in 2.3 has continued in this release. Play 2.4 requires Java 8 and uses Lambdas and Default Methods in Play's Java-API.
Slick, Typesafe's database query and access library for Scala, now supports the Reactive Streams API in the just released version 3.0. This enables developers to query their databases asynchronously and non-blocking. InfoQ talked to Slich Tech-Lead Stefan Zeiger to learn more about the new features and what they've planned for the future.
At Craft Conference 2015, Adrian Trenaman discussed the evolution of the Gilt.com architecture from a monolithic Ruby on Rails application to a cloud-based microservice ‘lots of small applications’ platform utilising Scala, Docker and AWS. Trenaman shared both technical and organisational lessons learnt from the past eight years, as Gilt has grown from a startup to a $1B company.
The recently released Maven 3.3.1 adds support for core extensions to be added to a project through additional metadata as well as using alternatives to the eponymous pom.xml file for building. This has been used to create build scripts for JRuby that build upon Maven but use a JRuby script to represent dependencies and plugins.
InfoQ reviews the results of the recent Typesafe survey of Java developers, focusing on the adoption of Java 8, and talks to Typesafe co-founder Jonas Bonér about the impact on Scala adoption for Java developers.
