Red Hat OpenShift

Introduction The GNU Toolchain is a collection of programming tools produced by the GNU Project. The tools are often packaged together due to their common use for developing software applications, operating systems, and low level software for embedded systems. This blog is part of a regular series covering the latest changes and improvements in the components that make up this Toolchain. Apart from the announcement of new releases however, the features described here are at the very bleeding edge of...

A new version of the OpenMP standard, 4.5, has been released in November 2015 and brings several new constructs to the users. OpenMP is an API consisting of compiler directives and library routines for high level parallelism in C, C++ and Fortran programs. The upcoming version of GCC adds support for this newest version of the standard. This post highlights some of the latest features, changes, and "gotcha's" to look out for. Taskloop construct Diving right in, the 'taskloop' construct...

Everything on a computer system eventually ends up being run as a sequence of machine instructions. People want to keep things simple and understandable even if that is not really the way that things work. The simple programmer's model of a Reduced Instruction Set Computer (RISC) processor executing those machine language instruction is a loop of the following steps each step finished before moving on the the next step: Fetch instruction Decode instruction and fetch register operands Execute arithmetic computation...

The current hype around the Internet of Things (IoT) has led to a substantial amount of innovation thanks to open source software, open hardware, open standards, and community inspiration. And even enterprises start to use the new hardware out there to optimize their offerings. Time for the Virtual JBoss User Group (vJBUG) to look into it in more details and welcome a very prominent guest speaker. Red Hat's Burr Sutter will be giving a session titled " An Enterprise Developer’s...

Today is a pretty exciting day if you’re an enterprise developer. . . Red Hat and Microsoft have announced that the two companies will be working together to bring a supported version of the .NET runtime to Red Hat’s Enterprise Linux and OpenShift 3. This offers developers more freedom and choice in how they develop their applications. Having spent a big part of my career at Microsoft and working with .NET since its inception, I’ve grown to love the strengths...

A huge problem facing modern enterprises is managing the large software systems and applications they deal with on a daily basis. Be it the CRM system purchased by a predecessor, a bundled HRM product thrown in to sweeten a deal, or the CMS that marketing could not live without, silos of information exist in the modern enterprise, and it can often be difficult to utilize the data that these systems contain. When an enterprise decides to buy a proprietary system...

Today is a very special day for me. I am pleased to announce that my thoughts around Enterprise Java development made it into a report and has been published by O'Reilly. The "Modern Java EE Design Patterns" mini-book is available for download as of today here . I am covering a lot of ground in this, beginning from the overall Enterprise challenges and changes over the last couple of years all the way down to microservices pattern. With plenty of...

Andrew Block of Red Hat will be speaking on this topic at DevOps Enterprise on 21 October - below is a primer from him on what he'll cover: Although the DevOps movement clearly and correctly centers around culture and the processes that guide or derail our success, the root of this shift often gets overlooked in favor of the symptoms. Sure, we all want our teams better aligned and more consistent, our processes streamlined and automated, our release cycles as...

This is a guest post written by Red Hat's own Gunnar Hellekson. I tend to pay attention to what Gunnar has to say and recommend the same. "There are three big challenges that lay between containers-as-toy and containers-as-infrastructure: Containers demand a lot more automation than you have now. Containers make you an operating system vendor. Containers drive organizational changes." Source: Red Hat: Containers for Grown-Ups - Tools Advisor

A number of Red Hatters are attending this week's NodeConf.eu as one of the event sponsors, but we're also here to learn more about Node.js and listen to some great sessions. Plus, I've met probably a dozen Red Hatters for the first time - most of whom are part of the Red Hat Mobile Application Platform team (formerly FeedHenry). Another nice benefit for this event is that it's in Waterford, Ireland, and specifically at Waterford Castle (TRULY - this is...

From the buzz on Twitter and blog posts, you could feel that ECMAScript 6 was finally coming. It has many things we’ve wanted for years, so it makes sense to start new projects with it in mind. ECMAScript 6 Others have written in depth about various ECMAScript 6 features . I’d like to focus just on one: module loading. There is no common way to load your ES6 modules natively in the browsers. For example babel , has support for...

At DevNation 2015 , Jason Hibbets shared a behind the scenes look at opensource.com , the talent behind it, their content strategy, and the results of the overall success of the site. Why I liked it? It was great to hear more about the inner workings of the opensource.com team. Most importantly, I found it very informative with specific info on how to get involved in the community that participates in the site. Read more about it – they are...

So Docker containers are all the rage, right? (If you didn't know this, you do now.) :) For a while now, Red Hatters have already been doing a ton of upstream container work on Docker, Kubernetes , and a new item called Nulecule . But while Docker containers have skyrocketed in popularity, there's been no convenient means to set up a development environment for building containerized apps. Wouldn’t it be handy to develop YOUR containerized apps for Red Hat Enterprise...

As part of our participation in hundreds of open source communities, Red Hat engineers are often involved in research and development efforts that may or may not become a part of Red Hat's supported offerings. Intel's Data-plane Development Kit (DPDK) is a set of libraries and drivers for Linux and BSD built for fast packet processing, for the burgeoning " Network Function Virtualization ", or NFV discipline. Typical verticals interested in turning Linux boxes into packet-processing machines are telecom, financial...

by Chris Aniszczyk, Head of Open Source, Twitter Apache Mesos is a resource manager for datacenter infrastructure that uses a 2-level scheduling model to provide hardware resources to various application frameworks.Similar to Infrastructure-as-a-Service (IaaS), Mesos manages hardware and the execution of applications, while delegating the responsibility of deployment to other platforms. In the Mesos’ model, application frameworks are responsible for scheduling and deployment logic. Multiple frameworks can be run on bare metal at the same time, using a single pool...

Red Hat's Arun Gupta, the Java guru, has this great talk at DevNation: Techniques such as automated builds and testing, continuous integration and continuous deployment allow software to be developed to a high standard and easily packaged and deployed to test environments, resulting in the ability to rapidly, reliably and repeatedly push out enhancements and bug fixes to customers at low risk and with minimal manual overhead. What container-agnostic tools are available for testing, continuous integration and deployment of a...

In many organizations development teams are split up from systems administrators. Both teams focus mainly on their roles and responsibilities, but this can lead to problems. Tensions between the groups can hinder your organization's efforts in getting the best product to the consumers in the shortest amount of time. Below are quotes which are commonly come up between developers and systems administrators. “Why doesn't the development team have to be on call? It's their code that breaks the system.” “Why...

Containerizing things is particularly popular these days. Today we'll talk about the idioms we can use for containerization, and specifically play with apache spark and cassandra in our use case for creating easily deployed, immutable microservices. Note: This post is done using centos7 as a base for the containers, but these same recipes will apply with RHEL and Fedora base images. There are a few different ways to build a container. For example, for beginners, you can build a container...
