Clojure development on the Android platform has been progressing remarkably in the last few years, allowing developers to use it in fully fledged apps such as SwiftKey’s Clarity Keyboard. Here we will review the current status of tools that support Clojure on the Android platform.
Apache has announced the EOL of version 1 of Log4j. Although Log4j version 2 was released in July 2014, version 1 was maintained until early August 2015. The new version is a full rewrite of the logging library, addressing many of the issues of version 1 and achieving unprecedented performance. Apache has made an effort to ease the upgrade, although advanced users may need some migration work.
This post covers scrum myths described by Ilan Goldstein, Certified Scrum Trainer.
At QCon San Francisco, we offer two days of workshops (Nov 19-20). Workshops focus on developing the technical skills that leverage technologies you heard about from our expert practitioners during the conference sessions. Here is a glimpse at some of the experts you can learn from QCon SF ‘15 workshops.
Frege, named after the German mathematician Gottlob Frege, is a purely functional, strongly typed language for the JVM that is so similar to Haskell that “most idiomatic Haskell code will run unmodified or with only minimal, obvious adaptions”. InfoQ has spoken with Ingo Wechsung, Frege’s creator.
RebelLabs published their Developer Productivity Report, the result of a survey started in March 2015, where they polled the Java development community on Java performance and performance testing methods. To see how these numbers line up with a real world experience, InfoQ spoke with Kirk Pepperdine, CTO at JClarity and well-known performance expert.
Oracle carved out some direction for the library class sun.misc.Unsafe, from the unsupported sun.misc package in a blog last week. At issue has been the concern that this heavily used class will have its access severely limited via Project Jigsaw's JDK modularization.
A zero-day vulnerability affecting sandboxed Java Web Start applications and sandboxed Java applets was recently announced, the first one for Java in nearly two years. Concerns that the vulnerability is already being exploited, together with the ease of exploitation, gave this vulnerability the highest CVSS risk score. Oracle has issued a patch and urges customers to upgrade as soon as possible.
The community has started discussions around what to do about sun.misc.Unsafe. Despite being part of an unsupported, proprietary API, this class is widely used by a number of popular tools due to its ability to provide low-level access to memory management. Given that Oracle has indicated their desire to remove this class at some point, developers are looking for viable alternatives.
JRuby released version 9000, the ninth release of the popular implementation of Ruby for the Java Virtual Machine. InfoQ speaks to Charles Oliver Nutter co-lead of the JRuby project and senior engineer at Red Hat about the release and about Ruby in general.
As previously mentioned on InfoQ, Oracle had proposed JEP 248, about making G1 the default garbage collector, to be included in the list of JEPs targeting Java 9; recently, Oracle has confirmed such decision and made it official. The decision triggered a lengthy debate in the HotSpot’s email discussion list, which concluded with a provision to defer the change if G1 proves not to be fully ready.
The OpenJDK Adoption Group is requesting community feedback on the newly announced comprehensive list of feature additions, changes and removals projected for Java 9. InfoQ talks to the Java Champions group about what to expect from Java 9 and how to get involved.
Richard and Raoul, who provide in person training courses on Java 8, offered a joint presentation at Devoxx UK 2015 where they discussed the origins and motivations for Generics in Java, some of the less known current features, and a glimpse of what might be coming up in Java 10. The presentation was split into three distinctive sections: past, present and future of Generics.
Today, the Eclipse Foundation announced the release of Eclipse Mars, the tenth annual combined release of Eclipse software. The Eclipse IDE incorporates additional Docker tooling, better Maven and Gradle support, enhanced Java 8 features and early access support for Java 9 via an additional install. Read on to find out more about the release.
