What’s new in TensorFlow machine learning

Wed, 15 Nov 2017 03:00:00 -0800

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 neural network library that predates TensorFlow but is quickly being displaced by it. The tf.keras API allows software using Keras to be transitioned to TensorFlow, either by using the Keras interface permanently, or as a prelude to the software being reworked to use TensorFlow natively.

What is Apache Spark? The big data analytics platform explained

Mon, 13 Nov 2017 03:00:00 -0800

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, Facebook, IBM, and Microsoft.

Out of the box, Spark can run in a standalone cluster mode that simply requires the Apache Spark framework and a JVM on each machine in your cluster. However, it’s more likely you’ll want to take advantage of a resource or cluster management system to take care of allocating workers on demand for you. In the enterprise, this will normally mean running on Hadoop YARN (this is how the Cloudera and Hortonworks distributions run Spark jobs), but Apache Spark can also run on Apache Mesos, while work is progressing on adding native support for Kubernetes.

Kotlin frameworks: A survey of JVM development tools

Thu, 09 Nov 2017 03:00:00 -0800

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 5.0 supports Kotlin extensions, offering an alternative to utility classes and Kotlin-specific class hierarchies, as well as adding Kotlin features to Spring itself.

Beta JetBrains IDE moves Kotlin apps out of the JVM

Mon, 06 Nov 2017 14:40:00 -0800

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, Ubuntu Linux, and Raspberry Pi.

Java 101: Datastructures and algorithms in Java, Part 2

Wed, 01 Nov 2017 12:14:00 -0700

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 used to search and sort one-dimensional arrays.

Note that this article builds on Datastructures and algorithms, Part 1, which introduces the theoretical side of datastructures and the algorithms associated with them. That article includes an in-depth discussion of algorithms and how to use space and time complexity factors to evaluate and select the most efficient algorithm for your Java program. This article will be much more hands-on, and assumes you have already read and digested Part 1.

ZGC large-heap Java garbage collector may go open source

Wed, 01 Nov 2017 11:21:00 -0700

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” for every workload, according to a proposal floated on an OpenJDK mailing list by Per Liden, a member of the HotSpot virtual machine team at Oracle. Liden’s proposal calls for creation of a ZGC project that he would lead, with the HotSpot group as sponsor.

Stack Overflow reveals the most-disliked programming languages

Wed, 01 Nov 2017 09:21:00 -0700

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 based on the Developer Story submissions on the Stack Overflow Jobs portion of the site. The data was released on Tuesday.

Which tools support Java 9’s new modularity features

Mon, 23 Oct 2017 03:00:00 -0700

With the release of Java 9 in late September, Java went modular, to improve scalability and performance and to let developers assemble custom configurations with just the functionality needed by an application. But the new Java Platform Module System features need development tools to really take advantage of them.

Here is where several key Java development tools stand in their modularity support.

Apache Ant: Ready for Java modularity

A Java library and command line tool used in building Java applications, Apache Ant is up to speed for Java 9 and modularity. The Ant project management committee has ensured Ant works on Java 9 with the February 2017 Ant 1.10.1 release. It supports module path and related options to the javac, java, and junit tasks.

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.
