  • FFmpeg's VP9 Decoder Is Much Faster Thanks To GSoC 2017

    As we previously reported on, there was a Google Summer of Code project this year optimizing FFmpeg's VP9 decoder particularly around AVX2 instructions and threading. The project was a success and VP9 decoding should be much faster with FFmpeg as a result.

    GSoC '17 student developer Ilia Valiakhmetov spent his time optimizing the FFmpeg VP9 code for AVX (Advanced Vector Extensions) as well as implementing tile threading support. His AVX2 optimizations are already in FFmpeg Git while his tile threading code is still being reviewed.

  • Chromium Now Supports GPU Sandboxing With Radeon Graphics On Linux

    Chrome/Chromium supports GPU sandboxing for security purposes and now it will work fine with the AMD graphics on Linux.

    As explained in this Git commit that was just merged minutes ago, "Default sandboxing fails for AMD platform as the GPU process spawns multiple threads. So GPU sandboxing needs to be started early. And all dependent libraries need to be preloaded."

Canonical/Ubuntu: Canonical's Engineering Tech Lead, Field Product Manager, and Designers'/Developers' Updates

  • A Complete Look At Spectre V1/V2/V4 & Meltdown
    Canonical's Engineering Tech Lead, Gavin Guo, has passed along a big slide deck on a presentation he is preparing about the Spectre and Meltdown CPU vulnerabilities. Gavin's presentation is mostly focused on Spectre V2 since that is vulnerable to attacking the host system from a guest VM, but the other vulnerabilities are also covered in his 77-page slide deck with great detail.
  • A unified OpenStack for a scalable open infrastructure
    Stu Miniman and John Boyer of theCUBE interviewed Mark Baker, Field Product Manager, Canonical at the OpenStack Summit in Vancouver. Read on to to find out about OpenStack’s increasing maturity. The Kubernetes and OpenStack story isn’t simple. Challenges exist, and plenty of pathfinding still needs to take place when it comes to Kubernetes. Customers want to take different approaches with how they want to plug together OpenStack components in order to create a unified stack is complex. Some customers want Kubernetes running alongside OpenStack, or on top of OpenStack, or even OpenStack running on Kubernetes.
