JAX London 2015, which took place from 12th to 15th October at the Business Design Centre in London, United Kingdom, gathered many of the experts in the areas of Java, Microservices and other modern development practices. Although the topics were varied, the overall message seemed to indicate both that these technologies are maturing, and that users are learning to use them more effectively.
C++14, the new C++ standard succeeding C++11, has been finally approved and is heading to ISO for publication this year. While improvements in C++14 are "deliberately tiny" compared to C++11, says C++ creator Bjarne Stroustrup, they still "add significant convenience for users" and are a step on the route to make C++ "more novice friendly."
Almost three years after the release of Java 7, Oracle last week released Java 8, touted as the most revolutionary Java release ever. This week Oracle presented a one-hour public webinar looking into features, background, and community reaction. InfoQ captured some important highlights of the webinar.
Speaking at the Hot Chips Conference, HSA Foundation president Phil Rogers has provided more details on plans to bring GPU acceleration to Java in time for Java 9 in 2015.
Oracle has released the first developer preview of Java 8 for the full range of platforms (Windows, Max OS X, Linux, Solaris).
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.
JDK 8 has reached Milestone 7 in JDK 8 build b91. M7 is the Feature Complete milestone, where all features and unit tests have been implemented and integrated. Unfortunately, not all features were delivered on time. Three JEPs (JDK Enhancement Proposal) are still in progress, althought they are estimated to be completed for JDK build b93.
Brian Goetz, Java Language Architect at Oracle and specification lead for the Lambda expressions project, has announced that mailing lists for JSR 335 will be made publicly available.
Brian Goetz has published an updated state of the lambda, giving a status report on the plan for adding lambdas to the Java language (also being tracked as JSR 335 and Java Enhancement Proposal number 126. Read on to find out what's new.
A view to the future after project Lambda has been shared on the Lambda-Dev mailing list, hinting at a more functional Java in future with the possibility of functional types post Java 8.
The lambda syntax is under discussion again at lambda-dev mail list, but this time, they're actively courting opinions. Four alternate syntaxes are proposed, and there's a survey to fill out to record your thoughts. Please take time to look at the syntax and vote on your favourites.
Now that the dust has settled on the future of OpenJDK and Plan B confirms the feature slip of Lambdas into JDK 8 (or later), what is the future of Lambdas themselves? The most recent proposal confirms that each lambda will be an instance of a type referred to as a SAM type; an interface, or abstract class, with exactly one abstract method. Read on to find out what's new.
Since the initial Lambda proposal was released (and the in-depth InfoQ analysis), there has been a subsequent state of the lambda which has significantly moved the goalposts of the lambda project in JDK 7. Read on to find out what's new.
