Several Red Hat engineers recently attended the JTC1/SC22/WG21 C++ Standards Committee meetings in Oulu, Finland. This post focuses on the sessions of SG1 (the standards committee sub-group 1 - for concurrency and parallelism) as well as on coroutines-related sessions. Jason already gave an overview of the meeting in his post. SG1 prioritized proposals and issues affecting the (expected) C++17 standard, followed by proposals targeting the Concurrency TS or a future revision of the Parallelism TS. We also made some progress...

Users have higher expectations than ever from applications. Your website or application has only 10 seconds to make a good impression, and only 20 min to help your users achieve a goal where they feel successful. How many of you are developers? (99% are developers in DevNation 2016 audience) How many of you have worked with a UX designer? (40% have worked with a UX designer). Regardless of whether you have a designer or not, you are responsible either alone...

The Problem Several months back, our emerging Developer Programs engineering team assembled during the last breaths of Brno's Czech winter and dedicated a full day towards a deceptively complex task: Be a user. Assemble in groups and, using a technology stack of your choosing, conceive of and create an application to be presented to the full team in 6 hours. Keep in mind that I hold my colleagues in extremely high regard; they're capable, creative, and experienced. Surely churning out...

OpenShift 3 is all about Docker containers. More importantly, it is about management orchestration of containerized applications. Red Hat IT was a big consumer of OpenShift 2 and likewise, we are moving as many applications as possible to containers. OpenShift 3 is a big part of this strategy. On a personal note, OpenShift 3 is an incredible product. I even have it installed at home for various services :) Grant Shipley gave his talk on "making applications great again" using...

Omair Majid, a Red Hat Senior Software Engineer, addressed the primordial issue of performance on the Java Virtual Machine. Performance issues of OS, CPU, Memory, and IO origins plague modern systems and present a complex issue to developers so the Thermostat tool focuses on alleviating and easing serviceability while enhancing monitoring of the JVM. After highlighting the problem many sources of performance information (CPU Usage, Memory Regions, GC, Classloading, JMX, JIT, IO calls, threading, etc...) and many ways to collect...

Red Hat's Peter Larsen, the OpenShift Domain Architect, gave a talk at DevNation, "Developing on OpenShift without the build waits". Developing with the OpenShift Platform-as-a-Service can be very compelling: developing and deploying software without having to worry about the infrastructure. When you first try OpenShift, it's quite impressive to see how easy it is to develop and deploy software using the built-in templates that include preconfigured components such as databases and application servers. This allows developers to start coding right...

During the DevNation General Session today we talked about how we need to rethink some of the basic concepts of software development. We think it's essential to make developers more effective and get started quickly. Rethinking what and how developers write and debug their code (what we normally call the "IDE") is central to that. Today, during the DevNation keynote, Red Hat announced that it is making a strategic investment in Eclipse Che. In this blog post I'll talk about...

"There is already a command line for it, why can't my favorite editor support this language?" As a developer, you're probably familiar with this sentiment, and in reality t here has never been a better time to be a software developer. Developers have access to a growing list of languages, frameworks, libraries, and technologies that can help them solve the problems they are tasked to tackle. However, the abundance of choices often hinders the ability of Integrated Development Environments (IDEs)...

Red Hat JBoss Core Services Collection is a group of common services that are critical for application developers. The services included change as new services and projects are added over time, but the idea is to include common, developer-friendly projects under a single subscription. The collection makes it much easier for developers to access these services. The launch of the Core Services Collection includes services that focus on three areas: web servers, security, and monitoring. New Components There are six...

We are proud to announce the release the Red Hat JBoss Developer Studio 10.

I was recently asked if we had a newsletter, so thought it was time to post it here as it's been some time since I last did. Our Red Hat Developer Program newsletter is a monthly email that highlights important technical updates from the previous month as well as important/useful items that are coming up. We (I) try to keep it brief with developer related information that you'll want to know about: announcements, articles, blogs, events, product updates, and webinars...

At Red Hat Mobile, we have been working hard over the last several months on exciting new technologies. Today we are happy to announce the general availability of Red Hat Mobile Application Platform 4.0. Following the success of our Hosted offering, we have taken the next step in the advancement of our product. Let's take a moment to recap on a couple of key technology choices we made over 5 years ago that have proven to be visionary decisions for...

Red Hat Linux was the first version of Linux I ever used. Until succumbing to The Cult of Macintosh a few years ago, I was a faithful Red Hat (and later Fedora) junkie. Hell, I still have my 15 year old Red Hat 7.2 discs. But, as a developer, it has been tough to do any substantial work with Red Hat Enterprise Linux (RHEL) unless working for an organization that has a license. That is, until relatively recently, when Red...

I'm guessing if you've done enough repeated builds on OpenShift, using Maven, that you are probably aware of the " download the internet" phenomenon that plagues build times. You start a build, expecting all those Maven dependencies you downloaded for your last build to be re-used, but quickly see your network traffic ramp up while the same 100MB of jars are downloaded again and again. Even builds of a few minutes tend to grind on me, frustrate me as a...

Earlier this year I attended the WG21 C++ standards committee meeting in Jacksonville, Florida, and as usual I spent most of my time in the Library and Library Evolution Working Groups. You can read about some of the other groups' work in Jason's Core report and Torvald's Parallelism & Concurrency report. As Jason wrote, several of the Technical Specifications published in the last few years were proposed for inclusion into the next revision of the C++ standard (C++17) and most...

Ready to develop container application in just over 4 minutes? Since I started playing around with OpenShift in its various forms, such as Online with cartridges and then later as containerized images, nothing has gotten me more excited than the availability of the Red Hat Container Development Kit (CDK). This kit has made it possible to easily gain access to a full, product based installation of OpenShift as you would interact with it in application development in just minutes. While...

Maybe you have so much memory in your computer that you never have to worry about it --- then again, maybe you find that some C or C++ application is using more memory than expected. This could be preventing you from running as many containers on a single system as you expected, it could be causing performance bottlenecks, and it could even be forcing you to pay for more memory in your servers. You do some quick "back of the...

In my previous article where I introduced atomic scan, I largely talked about using atomic to scan your containers and images for CVE Vulnerabilities. I also discussed how atomic scan had been architected to a plug-in approached so that you can implement your own scanners. The plug-ins do not have to focus on vulnerabilities, it could be as simple a scanner that collects information about containers and images. In this blog, I will walk through how you can create your...

Red Hat JBoss Fuse is an open source, lightweight and modular integration platform that allows you to connect services and systems across your entire application portfolio. And if you're familiar with Fuse, you're probably familiar with the Fuse Tooling that comes with Red Hat JBoss Developer Studio. As I mentioned in an earlier post, the 8.0.0.Beta2 version of JBoss Fuse Tooling is now available. Apart from the diagram tooling rework, there is yet another new, awaited feature. You can find...

If you are a developer working on integration projects with JBoss Fuse, you'll be happy to hear that the Fuse tooling has recently been reworked to provide a brighter look and feel, a more sensible, approachable automatic layout. The work is still in progress, but already available in beta. It can be installed into the new JBoss Developer Studio version 9.1.0.GA. To check out the latest features, please install the latest JBoss Developer Studio (available here). Then follow the steps...
