TensorFlow, Google’s contribution to the world of machine learning and data science, is a general framework for quickly developing neural networks. Despite being relatively new, TensorFlow has already found wide adoption as a common platform for such work, thanks to its powerful abstractions and ease of use.

TensorFlow 1.4 API additions

TensorFlow Keras API

The biggest changes in TensorFlow 1.4 involve two key additions to the core TensorFlow API. The tf.keras API allows users to employ the Keras API, a … Read the rest

From its humble beginnings in the AMPLab at U.C. Berkeley in 2009, Apache Spark has become one of the key big data distributed processing frameworks in the world. Spark can be deployed in a variety of ways, provides native bindings for the Java, Scala, Python, and R programming languages, and supports SQL, streaming data, machine learning, and graph processing. You’ll find it used by banks, telecommunications companies, games companies, governments, and all of the major tech giants such as Apple, … Read the rest

Kotlin, the statically typed alterative Java language for JVM and Android development, is showing signs of making it into the big leagues, getting support in development frameworks.

For example, the Spring Framework now supports Kotlin. And there are new frameworks such as Javalin and Ktor that support Kotlin.

Kotlin frameworks: Support in the Spring Framework

Best known as a venerable Java framework featuring dependency injection, Pivotal’s Spring Framework gained Kotlin support in the Spring 5.0 version released this year. Spring … Read the rest

Eclipse continues to be one of the most popular developer IDEs, thanks in large part to the broad ecosystem of plug-ins the platform supports. It may have begun as a tool for Java, but more and more people use it for other languages and frameworks, from Scala and Kotlin to JavaScript and Node.js. 

All of this is possible because Eclipse has a good architecture for plug-ins. Big tools and little tools can be added to your copy of Eclipse to … Read the rest

JetBrains has made available the Kotlin/Native technology, which creates native binaries for Kotlin code so they can run without a Java virtual machine. A beta version of the CLion IDE allows Kotlin programs to be compiled directly to an executable machine-code format.

Kotlin is a statically typed Java language alternative that began on the JVM. But many platforms can’t run JVMs, restricting the use of Kotlin to JVM-friendly platforms like Android. The Kotlin/Native preview’s supported target platforms include MacOS, iOS, … Read the rest

An array is a fundamental datastructure category, and a building block for more complex datastructures. In this second part of my Java 101 introduction to datastructures and algorithms, you will learn how arrays are understood and used in Java programming. I introduce the concept of an array and how arrays are represented in the Java language. Then you’ll learn about one-dimensional arrays and the three ways that you can introduce them to your Java programs. Finally, we’ll explore five algorithms … Read the rest

An Oracle-developed, low-latency Java garbage collector geared to large heaps could move to the open source community, if a proposal to do so gets community approval. Votes are due by November 8.

Called the Z Garbage Collector (ZGC), the project is designed to support multiterabyte heaps, have pause times not exceeding 10 milliseconds, and offer no more than a 15 percent application reduction throughput compared to the G1 garbage collector.

But ZGC’s developers don’t see these goals as “hard requirements” … Read the rest

When it comes to which languages developers like and dislike, Stack Overflow has some insight. Based on the languages developers tagged as those they would not like to work with in their Stack Overflow Jobs profiles, the company has found that Perl, Delphi, Visual Basic for Applications (VBA), and PHP are the most disliked programming languages, while R, Kotlin, TypeScript, and Rust are the least disliked.

Stack Overflow, which provides an online community for developers, studied the popularity of languages Read the rest

The Apache Foundation has added a new machine learning project to its roster, Apache PredictionIO, an open-sourced version of a project originally devised by a subsidiary of Salesforce.

What PredictionIO does for machine learning and Spark

Apache PredictionIO is built atop Spark and Hadoop, and serves Spark-powered predictions from data using customizable templates for common tasks. Apps send data to PredictionIO’s event server to train a model, then query the engine for predictions based on the model.

Spark, MLlib, … Read the rest
