Developer Tools

Today's announcement of Red Hat OpenShift.io was followed by a full day of developer toolset Summit sessions. These were presented by the OpenShift.io product development team and covered some truly amazing OpenShift.io features. While there are too many features to cover in a single blog post, these were my top 7 items. 1. A Kanban board that is actually useful OpenShift.io is built from the ground up for development teams to rapidly release software. This is one of the primary...

Developers often ask themselves these questions: Is this the right dependency to add for the feature that I need to build? What open source libraries and/or packages are others using? Is this a stable and secure version? Does this package's license conform to my organization's policies? These are important questions that developers need to answer when choosing open source software components for their project. It is nearly impossible to deliver a modern application without depending on a number of software...

Installing software is a drag Getting a team set up to work on a new software project can be quite time consuming. You have some great ideas for the code you want to write, but you can’t get down to writing it until you have a development environment for yourself and the rest of the team. First, you have to select, download, and install tools. There are usually some settings that need to be configured for each one. Then, every...

Digital transformation is about evolving into a technology business to compete in the digital economy. Businesses can’t transform without relying on the developer to implement the transformation strategy and deliver value. Unfortunately, as developers look to adopt new approaches that let them deliver business value more quickly, they find it challenging to get started in a timely fashion. First, they have to pick a software stack to use as a foundation. In the world of open source, there is an...

You may have read or heard that we folded DevNation into Red Hat Summit this year, which means that every Summit attendee has access to developer-related sessions, labs, and more! Here are some highlights to look forward to at Red Hat Summit (and why you should attend): LOTS of developer content. This is possibly the largest Red Hat-hosted commercial developer event ever with nearly 150 developer-related sessions, labs, BoFs, Lightning talks, CodeStarters [1], classes, and demos, plus nearly 50 Red...

(Part 2)Note: This article describes the functionality found in the Red Hat Container Development Kit 3.0 Beta. Features and functionality may change in future versions.

A year ago Red Hat announced the availability of a no-cost Red Hat Enterprise Linux developer subscription available as part of the Red Hat Developer Program. Offered as a self-supported, development-only subscription, this developer subscriptions provides you with a stable development platform for building enterprise applications - across cloud, physical, virtual, and container-centric infrastructures. Adoption has been excellent since then, but I was prompted (aka nudged, voluntold) to remind "non users" (yes, some of you are still out there) what...

Hi there! It's been a while since I last wrote an article. Today, I want to show you how to easily setup some persistent storage for your projects in minishift / CDK 3 (Red Hat's Containers Development Kit 3). Prerequisites First, let's start planning what you'll need: A working minishift or CDK 3. That's all, I swear! I won't go deep into how to set up a minishift or CDK 3, there are many articles on the Internet to cover...

What can be done to help the OpenJDK JVM play well in the world of Linux Containers? I thought I'd start tackling this issue by answering some frequently asked questions: Why is it when I specify -Xmx=1g my JVM uses up more memory than 1gb of memory? Specifying -Xmx=1g is telling the JVM to allocate a 1gb heap. It's not telling the JVM to limit its entire memory usage to 1gb. There are card tables, code caches, and all sorts...

An in-memory data grid is a distributed data management platform for application data that: Uses memory (RAM) to store information for very fast, low-latency response time, and very high throughput. Keeps copies of that information synchronized across multiple servers for continuous availability, information reliability, and linear scalability. Can be used as distributed cache, NoSQL database, event broker, compute grid, and Apache Spark data store. The technical advantages of an in-memory data grid (IMDGs) provide business benefits in the form of...

If you're are anything like me, you find the easiest -- yet still best -- way to get things done. After all, life is too short to write programs using Edlin, so give me Visual Studio Code (VS Code). So, what's an easy way for a Windows .NET developer to write code for Linux? Enter the Red Hat Development Suite, a zero-cost bundle for running Linux on your Windows PC, including running .NET Core. After installing the Red Hat Development...

While validating OpenShift Container Platform on a VMware platform the usage of Atomic OS was also a requirement. In the initial reference architecture, the decision was made to use Red Hat Enterprise Linux as the platform. This platform was then customized and the same packages as in Atomic were installed via Ansible and Red Hat Network. The github repo with those playbooks is here: https://github.com/openshift/openshift-ansible-contrib/tree/master/reference-architecture/vmware-ansible . These playbooks will guide you from start to finish to deploying OCP on VMware...

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.

(See this article to install GCC 7 on Red Hat Enterprise Linux.) In C and C++, the cases of a switch statement are in fact labels, and the switch is essentially a go to that jumps to the desired label. Since labels do not change the flow of control, one case block falls through to the following case block, unless terminated by a return, a break, a no return call or similar. In the example below, " case 1" falls...

Red Hat Summit 2017 is nearing (May 2-4, Boston) and more than ever will include more advanced application development sessions, CodeStarters, labs, birds of a feathers, etc. Visit the new "Developer Zone" in the expo area to try out new technologies for modern application development, attend sessions and earn “Developer Dollars” to buy cool swag (maybe a hoodie or other cool stuff??), and be sure to catch the opening keynote (May 2, 8:30 AM) for a fun demo of developer...

Introduction In my last blog, I mentioned I was asked to look at a malloc performance issue, but discussed the methods for measuring performance. In this blog, I'll talk about the malloc issue itself, and some measures I took to address it. I'll also talk a bit about how malloc's internals work, and how that affects your performance. First off, a bit of terminology - throughout this blog, these terms are defined to mean as follows... memory a region of...

In 2016, many improvements happened in the ABI static analysis framework that is Libabigail. In this article we'll present how fedabipkgdiff, a new Libabigail tool can help Fedora users, developers and others to analyze ABI changes of libraries carried by packages of the distribution.

The Raspberry Pi Model B was released in 2012 and, since then, a number of useful applications regarding this device have ensued. However, one particular application that is seldom overlooked when dealing with the Raspberry Pi is its ability to be used as a Stratum 1 NTP server and allow you to synchronize clocks across networks like the Internet. For me, this useful trick has actually made my entire office far more efficient. What is Stratum 1 NTP? Although many...
