Kotlin could overtake Java on Android next year

Tue, 10 Oct 2017 13:39:00 -0700

Kotlin is on its way to overtaking Java on that mobile platform, claims mobile database maker Realm.

Realm performed an anonymized assessment of 100,000 developers using its database and which languages they were using, determined by developers’ selection of SDKs. Realm found that 20 percent of apps built with Java before Google’s May endorsement of Kotlin are now being built in Kotlin.

Based on that data, Realm predicts Kotlin will overtake Java on Android by December 2018. Kotlin may even change how Java is used on the server, the company said: “In short, Android developers without Kotlin skills are at risk of being seen as dinosaurs very soon.”

API-driven development with OpenAPI and Swagger

Tue, 10 Oct 2017 11:48:00 -0700

While you were getting your coffee, Java application development changed--again.

In a world driven by rapid change and innovation, it's ironic that APIs are making a comeback. Like the coding equivalent of New York City's subway system in the age of autonomous cars, APIs are old tech--ancient but indispensable. What's interesting is how this invisible, everyday IT architecture is being re-envisioned and used in current technology trends.

While APIs are everywhere, they've become especially prominent in their remote incarnation as RESTful services, which are the backbone of cloud deployments. Cloud services are public APIs, which are characterized by public-facing endpoints and published structures. Cloud-based apps are also trending toward microservices, which are independent but related deployments. All of these factors increase the prominence of APIs.

Java microservices profile gets fault-tolerance capabilities

Fri, 06 Oct 2017 15:45:00 -0700

The Eclipse Foundation’s MicroProfile project to add microservices to enterprise Java has released MicroProfile 1.2, which adds capabilities for fault tolerance and security.

New features in MicroProfile 1.2

A fault-tolerance API in MicroProfile 1.2 provides a way for applications to deal with the unavailability of a microservice, said IBM Distinguished Engineer Ian Robinson, who has worked on MicroProfile. When old-style monolithic applications fail, they bring down the entire application. But applications composed of microservices continue to operate if a specific microservcie fails, leading to “more interesting failure scenarios,” he said. To deal with service failures, applications need a way of handling the unavailability of a service, such as to resort to a fallback service if a primary service is unavailable. Such fallbacks are what MicroProfile 1.2 allows.

Under Eclipse, changes to Java EE begin

Tue, 03 Oct 2017 06:30:00 -0700

As part of the change in ownership of Java EE (Enterprise Edition) from Oracle to the Eclipse Foundation, how Java EE works and is managed are starting to change.

For one, Oracle is making the Java EE technology compatibility kits (TCK), which ascertain if an implementation is compliant with Java, available via open source. Eclipse Executive Director Milinkovich called this “a very fundamental change to the dynamics of this ecosystem.”

Under the open-sourcing of the TCKs, users themselves can test for compliance instead of relying on what Milinkovich termed the previous “pay-to-play model” to confirm compliance—with Oracle using the TCKs as a way to exercise control over the Java EE ecosystem, he said. This open-sourcing of the TCKs should hopefully bring other providers to Java EE table, building implementations, Milinkovich added.

What's new in Kotlin 1.2? Code reuse, for starters

Tue, 03 Oct 2017 03:00:00 -0700

Version 1.2 of the statically typed Kotlin language, will offer an experimental feature enabling reuse of code across platforms, as well as compatibility with the Java 9 module system. The beta of Kotlin 1.2 is now available for download.

Kotlin’s experimental multiplatform projects capability lets developers reuse code between supported target platforms: JVM and JavaScript initially, and later native. Code to be shared between platforms is placed in a common module; platform-dependent parts are put in platform-specific modules. During compilation, code is produced for both the common and platform-specific parts.

Java debugging comes to Visual Studio Code

Mon, 02 Oct 2017 03:00:00 -0700

Microsoft has released a Java debugger for its free open source editor, Visual Studio Code. The newly minted extension is intended to work as a companion to the Language Support for Java extension provided by Red Hat.  

Whereas Red Hat’s Language Support for Java extension provides IntelliSense capabilities and Java project support, it does not include debugging capabilities. Microsoft’s Java Debug Extension works with previous Red Hat’s extension to provide them. Still in a preview mode, the Java Debug Extension offers capabilities including launch/attach, breakpoints, control flow, data inspection, and a debug console. The Microsoft and Red Hat extensions are available separately or in the Java Extension Pack, which bundles both together in a single install. Microsoft’s plans call for enabling a modern workflow for Java, with more features and extensions planned going forward.

GraphLib: An open source Android library for graphs

Thu, 28 Sep 2017 00:00:00 -0700

Graphs and data plots are wonderful tools for illustrating relationships, depicting data trends, and tracking goals in your Android applications. I saw this for myself several years ago, when a former student of mine won first place in a student mobile app competition sponsored by the Charleston Defense Contractors Association. A key feature of the winning app, "Diabetes and Me," was the ability to graph daily sugar levels.

As another example, consider a weight-tracking application that plots progress against a goal weight. Figure 1 illustrates how such an application might look on an Android phone. The figure uses a red line-graph to show average monthly weights for the year 2017. It shows the goal weight as a green straight line near the bottom. (Although the data values shown in the line graph are hypothetical, they are realistic pertaining to the author of this article.)

Google App Engine adds support for Java 8

Wed, 27 Sep 2017 12:55:00 -0700

Google has made the Java 8 runtime generally available on App Engine, the Google Cloud Platform’s development platform service. Google said the upgrade removes performance limitations Java developers have had to deal with when using the Java 7 runtime. Java 7 remains a supported option. 

“Unfortunately, using Java 7 on App Engine standard environment also required compromises, including limited Java classes, unusual thread execution, and slower performance because of sandboxing overhead,” said Amir Rouzrokh, Google product manager.

NoSQL standouts: The best key-value databases

Wed, 13 Sep 2017 03:00:00 -0700

Most any application needs some form of persistence—a way to store the data outside of the application for safekeeping. The most basic way is to write data to the file system, but that can quickly become a slow and unwieldy way to solve the problem. A full-blown database provides a powerful way to index and retrieve data, but may also be overkill. Sometimes all you need is a quick way to take a freeform piece of information, associate it with a label, stash it somewhere, and pull it back out again in a jiffy.
