  • The full-time job of keeping up with Kubernetes

    TL;DR - Unabated 1.xx major “minor” releases of “vanilla” upstream Kubernetes every three months could continue forever. You have to keep up, while also paying close attention to Kubernetes API object versioning. This relentless pace is the key ingredient in Kubernetes’ domination of the distributed infrastructure world.

  • Correctly integrating containers

    Kubernetes supports different ways of making containers and microservices contact each other, from connections with the hardware in the data center to the configuration of load balancers. To ensure communication, the Kubernetes network model does not use Network Address Translation (NAT). All containers receive an IP address for communication with nodes and with each other, without the use of NAT.

    Therefore, you cannot simply set up two Docker hosts with Kubernetes: The network is a distinct layer that you need to configure for Kubernetes. Several solutions currently undergoing rapid development, like Kubernetes itself, are candidates for this job. In addition to bandwidth and latency, integration with existing solutions and security also play a central role. Kubernetes pulls out all stops with the protocols and solutions implemented in Linux.

FreeBSD 12.0-RC1 Released, Fixes Ryzen 2 Temperature Reporting

Arguably most user-facing with this week's FreeBSD 12.0-RC1 release is updating the amdsmn/amdtemp drivers for attaching to Ryzen 2 host bridges. Additionally, the amdtemp driver has been fixed for correctly reporting the AMD Ryzen Threadripper 2990WX core temperature. The 2990WX temperature reporting is the same fix Linux initially needed to for a 27 degree offset to report the correct temperature. It's just taken FreeBSD longer to add Ryzen 2 / Threadripper 2 temperature bits even though they had beat the Linux kernel crew with the initial Zen CPU temperature reporting last year.

GPU/Graphics: DRM/KMS and CUDA

  • Google's Pixel 3 Is Using The MSM DRM Driver, More Android Phones Moving To DRM/KMS Code
    It turns out Google's recently announced Pixel 3 smartphone is making use of the MSM Direct Rendering Manager driver associated with the Freedreno open-source Qualcomm graphics project. Google is also getting more Android vendors moving over to using DRM/KMS drivers to power their graphics/display. Alistair Strachan of Google presented at this week's Linux Plumbers Conference and the growing adoption of Direct Rendering Manager / Kernel Mode-Setting drivers by Android devices.
  • Red Hat Developers Working Towards A Vendor-Neutral Compute Stack To Take On NVIDIA's CUDA
    At this week's Linux Plumbers Conference, David Airlie began talking about the possibility of a vendor-neutral compute stack across Intel, Radeon, and NVIDIA GPU platforms that could potentially take on NVIDIA's CUDA dominance. There has been the work on open-source NVIDIA (Nouveau) SPIR-V compute support all year and that's ongoing with not yet having reached mainline Mesa. That effort has been largely worked on by Karol Herbst and Rob Clark, both open-source GPU driver developers at Red Hat. There has also been other compute-motivated open-source driver/infrastructure work out of Red Hat like Jerome Glisse's ongoing kernel work around Heterogeneous Memory Management (HMM). There's also been the Radeon RADV driver that Red Hat's David Airlie co-founded and continues contributing significantly to its advancement. And then there has been other graphics/compute contributions too with Red Hat remaining one of the largest upstream contributors to the ecosystem.

Endless OS Switching To The BFQ I/O Scheduler For More Responsive Linux Desktop

While Con Kolivas' kernel patch series decided to do away with BFQ support, the GNOME-aligned Endless OS Linux distribution has decided to do the opposite in move from CFQ as the default I/O scheduler over to BFQ. Endless OS has decided to switch to the BFQ (Budget Fair Queuing) I/O scheduler since it prioritizes interactive workloads and should make for a better experience for its users particularly when applications may be upgrading in the background. During heavy background I/O, Endless found that their launch time of LibreOffice went from taking 16 seconds with CFQ to just three seconds when using BFQ. Other tests were also positive for improving the interactivity/responsiveness of the system particularly during heavy background I/O. Read more

Goa to train teachers in new open-source software apps for cyber security

After working with Google India for wider adoption of internet safety in schools two years ago, Goa education agencies will implement another project to train computer, information and communication technology school and higher secondary teachers in new open-source software applications for cyber security integration. The State Board of Secondary and Higher Secondary Education and Goa State Council Educational Research and Training (GSCERT) have decided to begin the second programme with over 650 computer teachers from December 4 to 18, Mr. Ajay Jadhav, Board of Study member and coordinator of the first project with Google, said on Friday. The cyber security training syllabus has been worked out and 18 resource persons are ready for the project. Read more
