  • CentOS Community Container Pipeline

    CentOS Community Container Pipeline empowers running a container registry (currently at to facilitate upstream and distro components to be delivered in a format suitable to be consumed by container tool chains on CentOS Linux.It enables upstream projects to build, test and deliver latest and safest container images, everytime and effortlessly (or with minimal efforts).

  • Testing Red Hat Enterprise Linux the Microsoft way

    Pairwise (a.k.a. all-pairs) testing is an effective test case generation technique that is based on the observation that most faults are caused by interactions of at most two factors! Pairwise-generated test suites cover all combinations of two therefore are much smaller than exhaustive ones yet still very effective in finding defects. This technique has been pioneered by Microsoft in testing their products. For an example please see their GitHub repo!

  • Red Hat brings legacy apps back to the future with Kubernetes

    Red Hat is expanding the application workload reach of Kubernetes in the latest version of its OpenShift Container Platform.

    The latest version, 3.5, is said to offer expanded support for traditional applications along with new security enhancements and more Kubernetes capabilities.

  • Why IBM Partnered with Red Hat

    IBM partnered with Red Hat to retain its dominance in the hybrid cloud

    Earlier in this series, we looked at the market expectations for International Business Machines’ (IBM) soon-to-be-announced fiscal 1Q17 results. Sticking to its strategy to grow Strategic Imperatives, IBM announced a cloud partnership with Red Hat (RHT) in late March 2017. Red Hat is an open source solutions provider.

    Under the deal, IBM will develop private clouds for its customers with the aid of Red Hat technology. In particular, IBM will use Red Hat Ceph Storage and Red Hat OpenStack Platform and offerings. Red Hat got access to Ceph software through its acquisition of Inktank in 2014.

  • HHVM 3.19 Brings CLI Server Mode, Retranslate-All, Performance Boosts

    Facebook developers have put out their latest release of HHVM to empower this PHP interpreter as well as what powers their Hack programming language.

    HHVM 3.19 is the new release this week and it ships with some interesting experimental features. First up, there is a "Retranslate All" feature to re-translate all profiled code into optimized translations after it hits a specified number of requests. This re-translate all can be used for getting better performance, quicker warmups, and more. This experimental feature will likely go on by default in HHVM 3.20.

  • Intel's Beignet Lands LLVM 4.0 Backend Support

    While Intel's Beignet is a terrific project especially when it comes to being a leading open-source OpenCL implementation that works with OpenCL 2.0 on GPUs (something that can't be said for Radeon with its open-source OpenCL stack consistently lacking and Nouveau not really being usable either), the sad part of it is that Beignet is consistently slow in supporting new versions of LLVM.

  • Salaries for storage, networking pros continue to rise

    Though salaries overall remained flat, most tech pros (61 percent) reported receiving a salary increase in 2016 and 9 percent reported a decrease, according to the survey. Increased compensation is the most common motivator employers provided to tech pros in 2016 (18 percent), followed by flexible work location and ability to telecommute (14 percent) and more interesting and challenging assignments (12 percent), according to the survey.

  • QA in Production

    Gathering operational data about a system is common practice, particularly metrics that indicate system load and performance such as CPU and memory usage. This data has been used for years to help teams who support a system learn when an outage is happening or imminent. When things become slow, a code profiler might be enabled in order to determine which part of the system is causing a bottleneck, for example a slow-running database query.

    I’ve observed a recent trend that combines the meticulousness of this traditional operational monitoring with a much broader view of the quality of a system. While operational data is an essential part of supporting a system, it is also valuable to gather data that helps provide a picture of whether the system as a whole is behaving as expected. I define “QA in production” as an approach where teams pay closer attention to the behaviour of their production systems in order to improve the overall quality of the function these systems serve.

Kubernetes, RancherOS, and Servers

  • Kubernetes is king in container survey

    Kubernetes is in, container registries are a dime a dozen, and maximum container density isn't the only thing that matters when running containers.

    Those are some of the insights gleaned by Sysdig, maker of on-prem and in-cloud monitoring solutions, from customers for how they're using containers in 2017.

  • RancherOS 1.0 Container-Optimized Linux Operating System Debuts

  • New Linux SSH server shows off Golang's infrastructure power

    Gravitational, maker of a software-as-a-service support system built with Kubernetes, has released the latest open source iteration of a key part of that system.

    Teleport, an SSH server that provides support teams with a simpler way to remotely manage server clusters, is an example of Google's Go language being used to devise safer but still performant replacements for critical infrastructure.

  • APIStrat Becomes a Linux Foundation and Open API Initiative Event

    The Linux Foundation, the nonprofit advancing professional open source management for mass collaboration, today announces that the API Strategy & Practice Conference has become a Linux Foundation event and will be jointly produced with the Open API Initiative (OAI), a Linux Foundation project. Linux Foundation events are where the world’s leading technologists meet, collaborate and innovate. APIStrat 2017 will take place October 31 – November 2 in Portland, OR.

  • Shrinking the Linux Kernel and File System for IoT

    At last year’s Embedded Linux Conference Europe, Sony’s Tim Bird warned that the stalled progress in reducing Linux kernel size meant that Linux was ceding the huge market in IoT edge nodes to real-time operating systems (RTOSes). At this February’s ELC North America event, another figure who has long been at the center of the ELC scene -- Free Electron’s Michael Opdenacker -- summed up the latest kernel shrinkage schemes as well as future possibilities. Due perhaps to Tim Bird’s exhortations, ELC 2017 had several presentations on reducing footprint, including Rob Landley’s Tutorial: Building the Simplest Possible Linux System.

    Like Bird, Opdenacker bemoaned the lack of progress, but said there are plenty of ways for embedded Linux developers to reduce footprint. These range from using newer technologies such as musl, toybox, and Clang to revisiting other approaches that developers sometimes overlook.

    In his talk, Opdenacker explained that the traditional motivator for shrinking the kernel was to speed boot time or copy a Linux image from low-capacity storage. In today’s IoT world, this has been joined with meeting the requirement for very small endpoints with limited resources. These aren’t the only reasons, however. “Some want to run Linux as a bootloader so they don’t have to re-create bootloader drivers, and some want to run to the whole system in internal RAM or cache,” said Opdenacker. “A small kernel can also reduce the attack surface to improve security.”

  • SDN dilemma: Linux kernel networking vs. kernel bypass

    If we've learned anything in the technology business in the last 25 years, it would be to never underestimate the Linux kernel. Why, then, have so many networking companies been so eager to bypass the Linux kernel -- or more specifically, the Linux kernel networking stack? What could be so wrong with the networking packet arteries in the Linux kernel that motivates so many of us to bypass them?

    There are two main reasons. First, the kernel networking stack is too slow -- and the problem is only getting worse with the adoption of higher speed networking in servers and switches (10GbE, 25GbE, and 40GbE today, and rising to 50GbE and 100GbE in the near future). Second, handling networking outside the kernel allows for plugging in new technology without the need to change core Linux kernel code.

Microsoft Begs, Bugs, and Bug Doors

  • Don't install our buggy Windows 10 Creators Update, begs Microsoft
    Microsoft has urged non-tech-savvy people – or anyone who just wants a stable computer – to not download and install this year's biggest revision to Windows by hand. And that's because it may well bork your machine. It's been two weeks since Microsoft made its Creators Update available, and we were previously warned it will be a trickle-out rather than a massive rollout. Now, Redmond has urged users to stop manually fetching and installing the code, and instead wait for it to be automatically offered to your computer when it's ready.
  • Microsoft Word flaw took so long to fix that hackers used it to send fraud software to millions of computers
    A flaw in Microsoft Word took the tech giant so long to fix that hackers were able to use it to send fraud software to millions of computers, it has been revealed. The security flaw, officially known as CVE-2017-0199, could allow a hacker to seize control of a personal computer with little trace, and was fixed on April 11 in Microsoft's regular monthly security update - nine months after it was discovered.

FOSS Licensing (and Lack Thereof)

  • Portugal to harmonise usability of govt portals
    All of the code, information and tools are made available for reuse.
  • JRC: ‘Releasing code without a licence hinders reuse’
    Projects that publish source code without a licence weaken the reusability of their code, warns Stefano Gentile, a copyright and trademark specialist working for the European Commission’s Joint Research Centre (JRC). Currently just 20 % of all projects published on GitHub, one of the most popular source code sharing platforms, have selected a licence for their work - down from about 60% in 2008, Gentile said, quoting numbers published in 2015 by GitHub.
  • React to React
