Business can’t win without developers, but you need more

Money can’t buy you happiness, but developers just might. According to a new survey from Stripe, companies finally recognize that access to engineering talent is a bigger inhibitor to growth than access to capital. In fact, as fed up as enterprises may be with their outdated IT infrastructure, they’re convinced that if they can just find good developers, most other problems will prove secondary.

Oracle forges a Java microservices framework

Oracle has introduced Project Helidon, an open source microservices framework for Java.

Helidon features a collection of Java libraries for writing microservices that will run on a web core powered by the Netty network application framework. The project also includes Helidon Reactive WebServer, which provides a functional programming model to run on Netty. Cloud application development is supported, along with health checks, metrics, tracing, and fault tolerance.

What is the JRE? Introduction to the Java Runtime Environment

Together, the Java Development Kit (JDK), the Java Virtual Machine (JVM), and the Java Runtime Environment (JRE) form a powerful trifecta of Java platform components for developing and running Java applications. I’ve previously introduced the JDK and JVM, and in this quick tutorial you’ll learn about the JRE, which is the runtime environment for Java.

Practically speaking, a runtime environment is a piece of software that is designed to run other software. As the runtime environment for Java, the JRE contains the Java class libraries, the Java class loader, and the Java Virtual Machine. In this system:

Kubeflow brings Kubernetes to machine learning workloads

Now in beta, the open source Kubeflow project aims to help deploy a machine learning stack on the Kubernetes container orchestration system.

The Kubeflow machine learning toolkit project is intended to help deploy machine learning workloads across multiple nodes but where breaking up and distributing a workload can add computational overhead and complexity. Kubernetes itself is tasked with making it easier to manage distributed workloads, while Kubeflow centers on making the running of these workloads portable, scalable, and simple. Scripts and configuration files are part of the project. Users can customize their configuration and run scripts to deploy containers to a chosen environment.

Review: MongoDB takes on the world

If you’ve built a medium-sized to large-scale web application in the last few years, you probably considered basing it on the open source LAMP or MEAN stack. The older LAMP stack uses the Linux operating system, Apache web server, MySQL relational database, and PHP programming language. MEAN uses the MongoDB NoSQL database, the Express back-end web application framework, the Angular application platform, and the Node.js JavaScript runtime. MEAN is essentially an end-to-end JavaScript stack. Linux isn’t explicitly mentioned in the acronym, but is usually the OS underneath Node.

Mastering Spring framework 5, Part 2: Spring WebFlux

Spring WebFlux introduces reactive web development to the Spring ecosystem. This article will get you started with reactive systems and reactive programming with Spring. First you’ll find out why reactive systems are important and how they’re implemented in Spring framework 5, then you’ll get a hands-on introduction to building reactive services using Spring WebFlux. We’ll build our first reactive application using annotations. I’ll also show you how to build a similar application using Spring’s newer functional features.

Reactive systems and Spring WebFlux

The term reactive is currently popular with developers and IT managers, but I’ve noticed some uncertainty about what it actually means. To get clearer on what reactive systems are, it’s helpful to understand the fundamental problem they’re designed to solve. In this section we’ll talk about reactive systems in general, and I’ll introduce the Reactive Streams API for Java applications.

15 great alternatives to React, Angular, and Vue

“The Sound of Music” may preach, “Let’s start at the very beginning, a very good place to start.” But almost every developer knows it is a foolish plan. The right place to start is with a firm foundation built by a great team of open source developers. Clone their hard work and then add just enough code to make it your own. There’s no need to repeat what everyone has done before.
