Red Hat
  • The State of Microservices

    During the fall of 2017, we conducted a microservices survey with our Red Hat JBoss Middleware and Red Hat OpenShift customers. From this, we were able to discover how these customers are using microservices to their advantage, what they see as some of the major benefits, what challenges exist and how to overcome them and how microservices can give respondents a competitive advantage. While these statistics are based off of a specific group of Red Hat customers, these findings give a good sense of the overall attitude toward microservices adoption and implementation. Read on to learn more about these findings.

  • What OpenShift Online and Dedicated customers should know about Meltdown and Spectre

    This past week, the technology world became aware of three significant security threats that could be used to allow cybercriminals to steal valuable data from an affected computer system. Together, these three bugs are commonly known as “Spectre” and “Meltdown” – a technical discussion of these vulnerabilities can be found here, and a non-technical explanation of the key facts is here.

  • F27-20180105 updated isos released

    The Fedora Respins SIG is pleased to announce the latest release of Updated 27 Live ISOs, carrying the 4.14.11-300 kernel.

  • Fedora 28 Looking To Promote Its AArch64 Server Support

    The latest in the long list of planned features/changes for Fedora 28 come down to an AArch64 promotion.

    Fedora developers are looking to promote their AArch64 / ARM64 / ARMv8 server offerings to being a "primary architecture" for this next Fedora release. The Fedora AArch64 server installer, Cloud images, and Docker base images would be the same status then as the other primary server architectures like x86_64.

  • PodCTL #20 – Gathering Kubernetes Communities

    Before Kubernetes became popular, we had a suspicion that these trends would happen and we started the OpenShift Commons community. Whereas the Kubernetes community is focused on the technology, the OpenShift Commons community strives to bring together both technologists and practitioners to share knowledge and work to solve common challenges.

  • 5 reasons Kubernetes is the real deal

    I've been to a lot of tech conferences in my life, but there was something different about the December 2017 KubeCon/Cloud Native Computing Foundation (CNCF) Summit in Austin. Sure, there's a ton of hype around Kubernetes, but it's something more. Not only did attendance go up by a staggering amount vs. 2016 (there were more than 4,000 people in Austin) but it was about who was and wasn't there. The content was solid, the Linux Foundation did its usual fabulous job running the event, but the real highlight for me was about the who.


    Many open source projects come from one developer's crazy/beautiful idea, but leave lots and lots to be done before the use cases are built out and proven. In this case, similar to MapReduce/Hadoop, the primary use case and even most key foundational technical elements have been proved out, in production at Google for years.

Fedora 28 Taking To Modularizing Their Anaconda Installer

Filed under
Red Hat

When talking about the Fedora/RedHat Anaconda installer it still brings back bad memories from the Anaconda fallout a few years ago when they went through some painful transitions that also led to release delays. In 2018, Fedora/RedHat developers are taking up the initiative of modularizing the Anaconda installer.

For the Fedora 28 release due out this spring, the plan is to split the Anaconda installer into several modules that in turn will communicate with eachother using a DBus API. The modularization effort sounds nice as long as it goes smoothly and doesn't lead to any fallout like with past Anaconda overhaul initiatives (though admittedly Anaconda has been playing nicely the past number of releases and no complaints on my end currently).

  • AMD Posts Last KFD Kernel Patches For Discrete GPUs, Needed For Upstream ROCm

    AMD has posted their remaining patches for now for getting the discrete GPU support upstream in the AMDKFD "Kernel Fusion Driver" that is part of their ROCm compute stack.

  • Xilinx ZynqMP DisplayPort DRM/KMS Driver Posted

    Xilinx is interested in contributing the latest DRM/KMS driver upstream.

    Xilinx has developed a new DRM/KMS driver for their DisplayPort sub-system that is part of their ZynqMP SoC. The Xilinx ZynqMP SoC has a full display pipeline and two planes and DisplayPort 1.2 encoder.

  • Tessellation Shaders Land For RadeonSI NIR Backend

    The work led by Valve Linux driver developer Timothy Arceri on adding tessellation shader support to RadeonSI's NIR code-path has been merged to Mesa 17.4-dev Git.

    RadeonSI Gallium3D has been working on a NIR back-end for eventually supporting SPIR-V ingestion as needed for OpenGL 4.6 compliance with code sharing with the RADV Vulkan code. Eventually though RadeonSI may eventually switch to using NIR completely as its intermediate representation. But before that can happen, the RadeonSI NIR support needs to get to parity with its existing OpenGL support when tied to TGSI IR.

  • Red Hat's Latest Nouveau Developer Posts Updated NIR Code

    Not only is RadeonSI working on NIR support but Red Hat has begun working on NIR support for the open-source NVIDIA "Nouveau" driver as part of a compute effort and possible Vulkan support in the future.

    As written about last month, longtime Nouveau contributor Karol Herbst has joined Red Hat and his first public-facing project is developing NIR support for Nouveau. In the original patch series Karol explained he's working on NIR support for Nouveau in order to get SPIR-V (the Vulkan / OpenCL IR) support moving. Their expressed focus right now is on SPIR-V compute support but this would also be a step towards Vulkan for this open-source, reverse-engineered NVIDIA Linux graphics driver.

  • Broadcom's Open-Source VC5 OpenGL & Vulkan Support Improving

    Broadcom open-source driver developer Eric Anholt has written his first status update on the VC5 driver activities of the new year.

    VC5 is the new Broadcom GPU capable of Vulkan and much greater OpenGL capabilities than the VC4 graphics processor most well known for being within current-generation Raspberry Pi devices. Eric has been working on the bring-up of the open-source VC5 driver stack for the past half-year and he continues making progress on getting the VC5 OpenGL Gallium3D driver closer to parity to the long-standing VC4 driver as well as working on "BCMV" as the new Broadcom Vulkan driver still in its early stages.

  • 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.

Fedora 28 To Work On Better VirtualBox Integration, Hardening Packages & Stronger Crypto

Filed under
Red Hat

With more developers returning to their activities after the holidays, feature work on Fedora 28 is heating up.

Recently proposed for Fedora 28 include:

VirtualBox Guest Integration - This is aobut having the VirtualBox guest drivers and tools ship by default in Fedora Workstation. This is part of an effort by Red Hat for getting more of the VirtualBox drivers mainlined in the Linux kernel. Basically if all goes well this means a smoother out-of-the-box experience when running Fedora on top of Oracle VM VirtualBox.

    Xiaomi promised that the Mi A1 would receive Oreo by the end of 2017, and the company hit a buzzer-beater by rolling out Android 8.0 to the Android One device on December 30th. But the kernel source code was nowhere to be found, a violation of the GNU General Public License, version 2 (GPLv2), and an affront to the development and enthusiast community. It's about two-and-a-half months late, but Xiaomi has finally released the Android 8.0 Oreo source code for the Mi A1.

Google recently published its "Android Security 2017 Year In Review" report where the company talks about how Android security has matured in the last few years and how it fights to find new ways to protect Android users from malware and all the other nasty stuff you obviously don't want to have on your mobile phone or tablet.

If you owned a 'fat' PlayStation 3 you could be entitled to $65 from Sony because of Linux option

Cast your mind back to when Sony released the original PlayStation 3, and you may well remember claims that the console was also a "computer". The claims were such that Sony suggested that owners could install Linux -- which, technically speaking, they could. However, installing Linux on a PS3 also posed something of a security issue, and Sony backtracked on the "Other OS" feature, killing it will a firmware update. Unsurprisingly, a lawsuit followed, and the result of this is that you could in line for a pay-out. Read more

  • Ramblings about long ago and far away
    I had originally run MCC (Manchester Computer Center Interim Linux) in college but when I moved it was easier to find a box of floppies with SLS so I had installed that on the 486. I would then download software source code from the internet and rebuild it for my own use using all the extra flags I could find in GCC to make my 20Mhz system seem faster. I instead learned that most of the options didn't do anything on i386 Linux at the time and most of my reports about it were probably met by eye-rolls with the people at Cygnus. My supposed goal was to try and set up a MUD so I could code up a text based virtual reality. Or to get a war game called Conquer working on Linux. Or maybe get xTrek working on my system. [I think I mostly was trying to become a game developer by just building stuff versus actually coding stuff. I cave-man debugged a lot of things using stuff I had learned in FORTRAN but it wasn't actually making new things.]

  • Ubuntu Tried Adding Synaptics Support Back To GNOME's Mutter
    GNOME developers previously dropped support for Synaptics and other input drivers from Mutter in favor of the universal libinput stack that is also Wayland-friendly. Canonical developers tried to get Synaptics support on X11 added back into Mutter but it looks clear now that was rejected. Canonical's Will Cooke reported in this week's Ubuntu happenings that they were trying to add upstream support for Synaptics to Mutter, complementing the libinput support. While it's great Canonical trying to contribute upstream to GNOME, Synaptics support was previously dropped as being a maintenance burden and with libinput support getting into rather good shape.
  • Long live Release Engineering
    y involvement in Fedora goes back to late 2003 early 2004 somewhere as a packager for I started by getting a few packages in to scratch some of my itches and I saw it as a way to give back to the greater open source community. Around FC3 somewhere I stepped up to help in infrastructure to rebuild the builders in plague, the build system we used before koji and that we used for EPEL(Something that I helped form) for awhile until we got external repo support in koji. I was involved in the implementation of koji in Fedora, I joined OLPC as a build and release engineer, where I oversaw a move of the OS they shipped from FC6 to F8, and laid a foundation for the move to F9. I left OLPC when Red Hat opensourced RHN Satellite as “spacewalk project” I joined Red Hat as the release engineer for both, after a brief period there was some reorganisation in engineering that resulted in me handing off the release engineering tasks to someone closer the the engineers working on the code. As a result I worked on Fedora full time helping Jesse Keating. When he decided to work on the internal migration from CVS to git I took over as the lead. [...] Recently I have accepted a Job offer to become the manager of a different team inside of Red Hat.
