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...

Red Hat Developer Toolset has already been available for nearly four years and Red Hat Software Collections has been out for two and a half. We've seen excellent adoption of these as more and more developers and customers utilize the newer technologies that become available. So, this week we announced more with these two new beta releases. New news Red Hat Software Collections 2.2 Beta includes: new open source databases (MariaDB 10.1, MongoDB 3.2 and PostgreSQL 9.5) new open source...

Several Red Hat engineers recently attended the JTC1/SC22/WG21 C++ Standards Committee meetings in March 2016 in Jacksonville, Florida, USA. This post focuses on the sessions of SG1 (the standards committee sub-group 1 - for concurrency and parallelism) and on several proposals related to coroutines. The biggest news from a parallelism and concurrency (P&C) perspective is that the Parallelism Technical Specification v1 was voted into the working draft of the standard. This means that C++17 will offer support for several parallel...

The GCC project has traditionally made major releases yearly in the March/April timeframe. March is rapidly approaching and the GCC project's engineers are busy polishing things up for the GCC 6 release. I'm going to take a short break from my own release efforts to briefly talk about some of the new features. Warnings GCC strives to implement warnings which help developers catch errors at compile time rather than allow potentially dangerous code to be silently accepted and ultimately deployed...

Abstract This project (part of Red Hat Lab Q) was initiated by Jan Zeleny to accommodate low-end and low-cost devices, which have usually slower hardware, and has particular usefulness to Fedora. Three students (Josef Řídký, Michal Ruprich, Šimon Matěj) from Faculty of Information Technology (FIT VUT Brno, Czech Republic) began work on the project with me (Petr Hracek) as a leader of the team. The aim Let’s say we have a device with low-cost hardware and we have Fedora/EPEL Linux...

Occasionally, there's a need for a new GNU C Library for a given application to run. For example, some versions of the Google Chrome browser started to warn users on Red Hat Enterprise Linux 7 that future versions of Chrome would not support their operating system. The Chromium source code contained a version check, flagging all versions of the GNU C Library (glibc) older than 2.19 as obsolete. This check has since been relaxed to 2.17 (the version in Red...

Hi Everyone, Welcome to a new blog about changes and new features in the GNU toolchain (compiler, assembler, linker and debugger). My intention is to post monthly updates highlighting what is new in these tools so that developers can keep abreast of the developing technologies. This first post covers changes made to the development versions tools in October and November of this year. Earlier posts in this series can be found in my live journal blog here, but future posts...

As always when we rebase GCC in Developer Toolset (as we announced yesterday) to a new major upstream release, there are a huge number of bugfixes, performance improvements, quality of implementation enhancements - the list goes on. In this article, however, I'd like to focus on four headline features and one new way of using the tools. Let's dive in. So firstly, OpenMP 4.0 is fully-supported for C, C++, and Fortran developers. Red Hat is a member of the OpenMP...

Our Red Hat Developers program team has just concluded a "Time to Hello World" project to reduce the time it takes you to download and install a new technology, and then get to your first "hello world" application. By utilizing multiple resources from Red Hat engineering, UX, evangelists, docs, testing, and yes, even customers, this is just one of many Red Hat activities underway to minimize speed bumps when trying a new Red Hat technology. So, is 6 minutes quick...
