What Is the Intersection of OpenStack and Kubernetes?

Lew Tucker is a busy man. Aside from his day job as VP and CTO for Cloud Computing at Cisco, Tucker also sits on the board of directors at both the OpenStack Foundation and the Cloud Native Computing Foundation, giving him a unique perspective on both organizations. Some in the industry have positioned Kubernetes as a competitive replacement for OpenStack, but that's not what Tucker sees. In a video interview, Tucker explains where the intersection currently exists between OpenStack and Kubernetes and why he expects both to be successful. Read more

Graphics: Vulkan, AMDGPU, Wayland

  • Vulkan Display Extensions To Be Used By SteamVR Merged Into Mesa RADV/ANV
    Keith Packard's long in development work for improving the Linux display stack infrastructure for better dealing with VR head-mounted displays is about rounded out with the new Vulkan extension support being merged into Mesa. Just over a year ago famed X developer Keith Packard started contract work for Valve to improve the plumbing around the Linux/X.Org support for virtual reality HMDs for better performance and better integration. Within the Linux kernel and the X.Org Server he's worked and landed the DRM leasing support of outputs to let a VR compositor (Steam VR) have direct access to the output, "non-desktop" quirk handling so VR HMDs don't become mapped as part of a standard Linux desktop, and related work.
  • A Slew Of AMDGPU DC Updates Published, Further Improvements For Raven Ridge
    There hasn't been a new AMDGPU DC code drop in a while as AMD developers work to improve their internal processes, but hitting the wire today is a set of 51 new patches for this "display code" stack that work on a variety of improvements.
  • Sway 1.0 Wayland Compositor Nears With Floating Windows, Tablet Support & More
    The release of the Sway 1.0 Wayland compositor is inching closer with the recent third alpha release. Sway for the uninformed is a very promising i3-compatible Wayland compositor. Earlier this month Sway 1.0 Alpha 3 was released to succeed the second alpha release from the month prior. Sway 1.0 is succeeding the Sway 0.15 changes with a great deal of improvements. Most notably with the 1.0 series is now requiring the WLROOTS modular Wayland compositor library.

Security: OpenBSD, FUD and More

  • OpenBSD Disabling SMT / Hyper Threading Due To Security Concerns
    Security oriented BSD operating system OpenBSD is making the move to disable Hyper Threading (HT) on Intel CPUs and more broadly moving to disable SMT (Simultanious Multi Threading) on other CPUs too. Disabling of Intel HT and to follow with disabling SMT for other architectures is being done in the name of security. "SMT (Simultanious Multi Threading) implementations typically share TLBs and L1 caches between threads. This can make cache timing attacks a lot easier and we strongly suspect that this will make several spectre-class bugs exploitable. Especially on Intel's SMT implementation which is better known as Hypter-threading. We really should not run different security domains on different processor threads of the same core." OpenBSD could improve their kernel's scheduler to workaround this, but given that is a large feat, at least for now they have decided to disable Hyper Threading by default. Those wishing to toggle the OpenBSD SMT support can use the new hw.smt sysctl setting on OpenBSD/AMD64 and is being extended to cover CPUs from other vendors and architectures.
  • Linux malware threats - bots, backdoors, trojans and malicious apps [Ed: Ignoring back doors in Windows and other proprietary platforms to instead focus on malicious software one actually needs to install on one's machine or choose a trivial-to-guess password (when there are open ports)]
  • Does Open Source Boost Security? Hortonworks Says Yes
    Organizations are best served security-wise if they favor and adopt open source technology — especially enterprise open source — over proprietary alternatives, according to Hortonworks. However, not everybody agrees that open source software intrinsically is more secure. It’s tough to argue that open source hasn’t brought significant benefits to the IT industry and the tens of thousands of organizations that rely on IT products to automate their operations. Starting with the introduction of Linux in the late 1990s, major swaths of the tech industry have shifted to open source development methodologies. That includes the vast majority of the big data ecosystem, which has been largely bootstrapped by various Apache Software Foundation projects.

Mozilla: Diversity & Inclusion in Open Source, VR, Phabricator, Rust and WebRender

  • Call for Feedback! Draft of Goal-Metrics for Diversity & Inclusion in Open Source (CHAOSS)
    In the last few months, Mozilla has invested in collaboration with other open source project leaders and academics who care about improving diversity & inclusion in Open Source through the CHAOSS D&I working group. Contributors so far include: Alexander Serebrenik (Eindhoven University of Technology) , Akshita Gupta (Outreachy), Amy Marrich (OpenStack), Anita Sarma (Oregon State University), Bhagashree Uday (Fedora), Daniel Izquierdo (Bitergia), Emma Irwin (Mozilla), Georg Link (University of Nebraska at Omaha), Gina Helfrich (NumFOCUS), Nicole Huesman (Intel) and Sean Goggins ((University of Missouri).
  • Introducing A-Terrain - a cartography component for A-Frame
    Have you ever wanted to make a small web app to share your favorite places with your friends? For example your favorite photographs attached to a hike, or just a view of your favorite peak, or your favorite places downtown, or a suggested itinerary for friends visiting?
  • Setting up Arcanist for Mozilla development on Windows
  • Taming Phabricator
    So Mozilla is going all-in on Phabricator and Differential as a code review tool. I have mixed feelings on this, not least because it’s support for patch series is more manual than I’d like. But since this is the choice Mozilla has made I might as well start to get used to it. One of the first things you see when you log into Phabricator is a default view full of information.
  • This Week in Rust 239
    This week's crate is SIMDNoise, a crate to use modern CPU vector instructions to generate various types of noise really fast. Thanks to gregwtmtno for the suggestion!
