  • Grab scales to meet business demands with open source IT automation and management

    By deploying Red Hat Ansible Tower, an enterprise open source IT automation and management solution, Grab increased its app uptime to 99.99%, reduced development and deployment time, and streamlined infrastructure management with role-based access and automated deployments. As a result, Grab’s users can access the app when needed, and its IT teams can ensure systems are stable and scale to match feature and user base growth.

  • Beta Testing in the Ever-Changing World of Automation

    The International Standards Organization (ISO) has been focused on the standards around quality versus usability over time. In 1998 ISO identified efficiency, effectiveness and satisfaction as major attributes of usability. In 1999 a quality model was proposed, involving an approach to measure quality in terms of software quality and external factors. In 2001 the ISO/IEC 9126-4 standard suggested that the difference between usability and the quality in use is a matter of context of use. ISO/IEC 9126-4 also distinguished external quality versus internal quality and defined related metrics. Metrics for external quality can be obtained only by executing the software product in the system environment for which the product is intended.

    This shows that without usability/human computer interaction (HCI) in the right context, the
    quality process is incomplete. The context referred to here is fundamental to a beta test where you have real users in a real environment, thereby making the case of the beta test stronger.

    Beta Testing Challenges

    Now that we know why beta testing is so very critical, let’s explore the challenges that are involved with a beta stage.

    Any time standards are included, including ISO/IEC 9126, most of these models are static and none of them accurately describe the relationship between phases in the product development cycle and appropriate usability measures at specific project milestones. Any standard also provides relatively few guidelines about how to interpret scores from specific usability metrics. And specific to usability as a quality factor, it is worth noting that usability is that aspect of quality where the metrics have to be interpreted.

  • OpenShift Commons Briefing #112: Kubernetes 1.9 Release Update with Derek Carr (Red Hat)

    In this briefing, Red Hat’s Derek Carr talks us through the recent Kubernetes 1.9 release features and functions and reviews what is in the works for release 1.10. The briefing is a great guide to the 1.9 Release which went out the door at the very end of 2017. The 1.9 release had a strong focus on fixing bugs, maturing existing features to beta or stable. For Kubernetes 1.9, “Stability” is a key feature with an emphasis on refining, polishing, scale, and tightening up production matters.

openSUSE Tumbleweed Users Get LibreOffice 6.1, Mozilla Firefox 61, and FFmpeg 4

The month of July 2018 was pretty busy for the openSUSE Tumbleweed development team, and the first two weeks of the month already delivered dozens of updates and security fixes. openSUSE developer Dominique Leuenberger reports that a total of nine snapshots have been released in July 2018 for the openSUSE Tumbleweed Linux operating system series, which follows a rolling release model where users install once and receive updates forever. As expected, these 9 snapshots bring numerous updates and bugfixes. Read more

Linux Kernel/Foundation

  • Linux Foundation Brings Power of Open Source to Energy Sector
    The Linux Foundation launched on July 12 its latest effort—LF Energy, an open-source coalition for the energy and power management sector. The LF Energy coalition is being backed by French transmission system operation RTE, Vanderbilt University and the European Network of Transmission System Operators (ENTSO-E). With LF Energy, the Linux Foundation is aiming to replicate the success it has seen in other sectors, including networking, automotive, financial services and cloud computing.
  • Marek Squeezes More Performance Out Of RadeonSI In CPU-Bound Scenarios
    AMD's leading open-source RadeonSI Gallium3D developer, Marek Olšák, sent out a new patch series this week aiming to benefit this Radeon OpenGL driver's performance in CPU-bound scenarios. The patch series is a set of command submission optimizations aimed to help trivial CPU-bound benchmarks to varying extents. In the very trivial glxgears, the patch series is able to improve the maximum frame-rates by around 10%.
