It has been a year since I posted the announcement about the availability of the Java Language Support for Visual Studio Code. During this past year, we made 10 releases, added various features, fixed many bugs but more importantly, we have constantly grown our user base and finally reached and passed a million downloads on the Visual Studio Marketplace. Fred Bricon, Snjezana Peco and I, as the core team have worked on the Java Language Server and the Visual Studio...

It has long been recognized that unconstrained growth of memory usage constitutes a potential denial of service vulnerability. Qualys has shown that such unconstrained growth can be combined with other vulnerabilities and exploited in ways that are more serious. Typically, the heap and stack of a process start at opposite ends of the unused address space and grow towards each other. This maximizes the flexibility to grow the regions over the course of execution of the program without apriori knowing...

Introduction I'm working on the upstream fabric8-wit project of openshift.io. In this Go project, we embrace testing as best as we can in order to deliver a stable component. Testing acts as our safety net to allow for fast-paced feature development. This blog post is about our recent change in our testing strategy. It is not as boring as it might sound at first. ;-) Problem description We've changed out the data-model quite a lot and it took us a...

Typical CI process (source: www.pepgotesting.com) Continuous Integration (CI) is a phase in the software development cycle where code from different team members or different features are integrated together. This usually involves merging code (integration), building the application and carrying out basic tests all within an ephemeral environment. In the past, the code was integrated at an “integration phase” of the software development life cycle. This phase came after different teams would have spent weeks, months or even years working in...

Several Red Hat engineers attended the JTC1/SC22/WG21 C++ Standards Committee meetings in July 2017. This post focuses on the sessions of SG1, the study group on parallelism and concurrency. We discussed several synchronization-related proposals, improvements for futures, and, of course, executors. Also, I proposed a few steps that the SG1 community could take to get more efficient in how it conducts its work, which are all inspired by how successful open source projects work. Most of the proposals we discussed...

Red Hat JBoss Fuse provides an open source, lightweight, modular platform that enables you to connect a variety of services and systems across your application environment. And, included with Red Hat JBoss Developer Studio, is the Fuse Tooling that helps you take advantage of that platform. The route editor initially focused on the parts of the Camel configuration inside the route or Camel context element, but in version 8.0.0, we began adding support for global elements such as data formats...

OpenShift Container Platform (OCP) offers many different types of persistent storage. Persistent storage ensures that data should be insistent between builds and container migrations. When choosing a persistent storage backend to ensure that the backend supports the scaling, speed, dynamic provisioning, RWX/RWO support and redundancy that the project requires. Container-Ready Storage (CRS), or native Gluster for OCP, is defined by the concept of persistent volumes, which are OCP created objects that allow storage to be defined and then used by...

Note: This is an updated version of a post I wrote for my private blog years ago. While working on the REST API of RHQ a long time ago, I had started writing some integration tests against it. Doing this via pure HTTP calls is very tedious and brittle. So, I was looking for a testing framework to help me and found one that I used for some time. I tried to enhance it a bit to better suit my...

EDI, or Electronic Data Interchange, has always been a challenging domain to support for organizations. As EDI standards cover a large range of industries, from supply chain to medical to financial services (FSI), the standards rapidly evolve and change over time, thus requiring constant maintenance. The sheer cost of maintaining standards is high, not only for organizations but also for EDI software vendors who struggle to keep up. The expensive fees paid to standards organizations and rapidly evolving releases are...

Android is one of the most used mobile operating systems in the market with an estimated market share of approximately 84.82%. Millions of apps loom in the Android OS, for various tasks and it's a shame that only a small percentage of the apps have a well-developed user interface (UI), which is flexible and adaptable to various mobile sizes. For an average user, they want their apps to look good and do well. However, if you are an app developer...

In the previous part of this blog, I talked about the most important steps to get your project to compile with the latest Framework version. The migration has been done through the first three steps mentioned here, and in this post, I will go over the least complicated steps of migration. Steps 4 and 5 cover the modernization of your project with the latest Framework 8 features. If you are in a hurry, you can do this later on as...

It’s been over a month since I spoke at the Red Hat Summit in Boston and now that the dust has settled, I thought you might be interested in reading a brief summary of my Lightning Talk on Five OpenShift Development Environments in Five Minutes. In the presentation, I spoke about five different ways that you can create an OpenShift development environment within minutes. This included oc cluster up, Vagrant All in One Box, Minishift, a Fabric8 technology, and the...

Surely, you too have been frustrated, while single-stepping optimized programs in symbolic debuggers, by the Brownian motion in the source code, and by never being sure, when you reach a certain source line (if you can reach it at all), whether or not earlier lines have taken effect. Our frustration is about to be significantly alleviated, thanks to two new pieces of technology about to be contributed to the GNU toolchain. Statement Frontier Notes are stable markers of source locations...

One question, which is often asked of me is “How do I quickly get new features into production?” This is the whole idea of microservices, to quickly move features into production. At this year’s Red Hat Summit, I spoke to this during my OpenShift Application Runtimes session, introducing it as an upcoming product. I spoke on integrating language runtimes into OpenShift and Kubernetes so that as you write Microservices you can leverage a lot of the features that are available...

The March/April C++ meeting was back in Kona, Hawaii again, only a year and a half after the last Kona meeting. As usual, Red Hat sent three of us to the meeting: Jonathan Wakely, Torvald Riegel, and me. The headline from the meeting was voting to submit C++17 for approval by the national bodies. There wasn't really any significant resistance. There was one new feature added in the final draft, namely std::byte, which was expected to go in at the...

Red Hat Container Development Kit (CDK) provides a Container Development Environment (CDE) that allows users to build a virtualized environment for OpenShift. This environment is similar to the user’s production environment and does not need other hardware or a physical cluster. CDK is designed to work on a single user’s desktop computer. The following instructions are to install and use CDK with Fedora 25, but can also be used for earlier versions of Fedora. A significant difference between CDK version...

Several Red Hat engineers attended the JTC1/SC22/WG21 C++ Standards Committee meetings in March 2017. This post focuses on the sessions of SG1, the study group on parallelism and concurrency. The major topics of work of the week were (1) further polishing of the parallel algorithms in the C++17 draft, (2) making progress on the executors proposal (which provides mechanisms to control how parallel work is executed, for example on which resources), and (3) continuing work on proposals targeting the Concurrency...

In a previous blog post, we explained how to deploy an existing JBoss BRMS/Drools rules project onto an OpenShift DecisionServer. We created a decision/business-rules microservice on OpenShift Container Platform that was implemented by a BRMS application. The polyglot nature of a microservice architecture allowed us to use the best implementation (a rules engine) for this given functionality (business rules execution) in our architecture. The project we used was an existing rules project that was available on GitHub. We did however...

In this article, I want to provide some background details about our recently developed demonstration video - “ Running Game of Life across multiple architectures with Red Hat Enterprise Linux “. This video shows the Game of Life running in a heterogeneous environment using three 64-bit hardware architectures: aarch64 (ARM v8-A), ppc64le (IBM Power little endian) and x86_64 (Intel Xeon). If you are not familiar with the rules of this cellular automaton, they are worth checking out via the reference...
