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.

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...

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...

Red Hat sent four engineers to the spring C++ meeting this year, in Lenexa, Kansas, a suburb of Kansas City. It was hosted by Perceptive Software, a division of Lexmark. The meeting went very smoothly overall; while there were some disagreements they were pretty cordial. The first disagreement came up during the Monday evening session when Bjarne was talking about his vision of C++17. He wants to see multiple big new features, lest people get bored with C++ after another...

VS. I've been involved with full-stack development for a while now, especially stacks involving single page apps. When choosing to go with a single page webapp the backend concerns change. While any backend will do the job (think ruby, python, java, etc.) more emphasis is placed on the front-end stack as most of the time is spent in Javascript and less in the backend language since that is not where the UI logic resides. This is liberating in some senses...

The Internet of Things represents outstanding opportunities for innovation and opens the door to new development projects. At its core is the need for next-generation intelligent systems to collect, analyze, and communicate data into actionable information. Red Hat is in a unique position to help developers architect those systems and bring about the promises of the IoT. In fact, Red Hat technology is already embedded in intelligent systems throughout the world to enable IoT use cases such as Smart Cities...

"Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees" -- Clean Code We spent 10 times more time reading code than writing it. Thus keeping code clean is essential for maintainability and company growth, but doing it by hand can be tedious. Let's take a look at some of the clean code practices and how we can use Eclipse to re-factor code faster. Change inline comments to sub method calls...

Last time we discussed de-duplicating some code. Today let us look into the effectiveness of refactored code, Java 8 support and moving/renaming code. But hold on, aren't method calls expensive? I took a course on compilers in University and did some research on the matter. In 1996 Java in-lining might have made sense. But nowadays the overhead that methods generate is relatively negligible, also the JVM is quite smart in optimizing bytecode by in-lining methods that make sense to in-line...
