This post was originally published on redhat.com. Part 1: Adding Unit Tests to Native iOS Red Hat Mobile Application Platform Application A robust and agile mobile application development environment requires continuous integration and delivery. It also requires an integrated and automated unit testing process that helps bring applications to market successfully. This two-part series details my work done at the Red Hat Open Innovation Labs and as a Mobile Technical Account Manager to capture these mobile innovations in a useful...

Microservices are currently enjoying immense popularity. It is rare to find a tech conference without at least a few mentions of them in corridor conversations or titles of talks, and for good reason: microservices can provide a path to better, more maintainable, higher quality software delivered faster. What's not to love? Of course there are the "negatives" and details in the implementation of microservices that can trip up even the most seasoned architect-developer, but at the same time we are...

The world is moving to microservices, where applications are composed of a complex topology of components, orchestrated into a coordinated topology. Microservices have become increasingly popular as they increase business agility and reduce the time for changes to be made. On top of this, containers make it easier for organizations to adopt microservices. Increasingly, containers are the runtimes used for composition, and many excellent solutions have been developed to handle container orchestration such as: Kubernetes/OpenShift; Mesos and its many frameworks...

Cross language development in one project In this tutorial style article I'll discuss how to configure Eclipse for Java Native Interface (JNI) development based on a sample project that you can copy and modify. I.e, you can have a single project that can be both Java and C at the same time, and support a full code navigation and debugging of both languages. This article is focused on the configuration of Eclipse rather than explaining JNI itself, however there are...

Welcome to the tenth and final installment of That App You Love, a blog series in which I show you how to you can make almost any app into a first-class cloud citizen. If you want to start from the beginning, jump back and check out Part 1: Making a Connection. You’ll need the docker service and the oc utility to follow along in this post; for instructions check out Part 5: Upping Our (Cloud) Game. Wow, we’ve come a...

Node.js is a JavaScript runtime built on top of Chrome's V8 JavaScript engine. It is highly event-driven, and leverages non-blocking I/O model that makes it lightweight, efficient, and incredibly productive to use. It's that last bit, "productive", that I want to focus on today. One of the things that i feel makes Node(and NPM) so great is the ease in which you can add and use third-party modules. As most node.js developers know, to start using an external module, you...

Accessible through the Red Hat Developer Program and related Red Hat Enterprise Linux subscriptions, including the no-cost Red Hat Enterprise Linux Developer subscription, Red Hat Developer Toolset enables developers to compile applications once and deploy across multiple versions of Red Hat Enterprise Linux. Updated components within Red Hat Developer Toolset 6.0 Beta include versions of: the GNU Compiler Collection (GCC) 6.2.1 the GNU Project Debugger (GDB)...

The recommended steps for setting up the Red Hat JBoss Developer Studio (JBDS), on all supported platforms, are found here. The instructions are pretty straight-forward and it is enough to get started right away - as long as you have a suitable java SDK installed on your machine. However, if I go along that path, I would later have to deal with the Java SDK updates to go along with the compatibility of the existing tools. Eventually, I may end...

James Kirkland is one of the architects involved in the new open source Kapua project on Eclipse.org. In this blog post he discusses how innovation happens when industry leaders collaborate to make their customers successful. Over the years, I’ve seen the beginning of a lot of open source projects, but the thing that excites me about the new Kapua project is that until now Eclipse IoT has been a set of individual projects that didn’t interrelate or even interoperate. (Read...

In the microservices landscape, the API provides an essential form of communication between components. To allow secure communication between microservices components, as well as third-party applications, it's important to be able to consume API keys and other sensitive data in a manner that doesn't place the data at risk. Secret objects are specifically designed to hold sensitive information, and OpenShift makes exposing this information to the applications that need it easy. In this post, I'll demonstrate securely consuming API keys...

GDB relies on libcc1's GCC and GDB plugins to implement the " compile code" feature, now extended to support the C++ language. The Compile and Execute machinery enables GDB users to compile and execute code snippets within the context of an existing process. This allows users to perform inspection and modification of the program state using the target language well beyond the feature set historically exposed by symbolic debuggers. Almost anything that can be expressed in C, and now also...

One of our most popular Red Hat JBoss BRMS demo's, and one that has been available for quite some time, is the CoolStore demo. The CoolStore demo shows how business rules can be used to calculate values like promotional and shipping discounts in a shopping-cart. It furthermore illustrates concepts like ruleflow-groups and dynamic rule updates using KieScanner. Rules and micro-services: the JBoss BRMS Decision Server One of the more interesting features we've recently released in the Red Hat JBoss BRMS...

Last June, Eclipse IDE had a great release, named Neon. It features, among many other less visible but still quite useful improvements, many new functionalities for everyone. If you did not migrate yet and are still using an older Eclipse version, just move to Neon right now, it’s worth it! For this Neon release, Red Hat managed to increase its contributions to the Eclipse IDE. The 2 main teams doing Eclipse IDE development (to package Eclipse IDE as .rpm for...

Red Hat Developers and author N. Harrison Ripps have just released the first pieces of a ten-part series ("That app you love") in which Harrison describes the process of deploying an application using containers into a clustered environment on the cloud. Using the ZRC IRC client as a sample application, Harrison demonstrates each step in the process of containerizing software, dealing with issues like statelessness, security, and robustness that are typically architectural hurdles for most development teams moving to a...
