  • LightNVM 2.0 Support Being Prepped For Linux 4.16

    LightNVM is the abstraction layer within the Linux kernel for supporting open-channel NVM Express solid-state drives. LightNVM 2.0 is on the way.

    LightNVM 2.0 is on the way and is currently available as a public draft specification. This updated specification will be released soon for dealing with these SSDs that leave management up to the operating system rather than the drive itself.

  • Input Drivers Are Being Prepped For Year 2038 Safety

    While kernel developers are busy with Spectre and Meltdown bugs right now, 20 years from now is the big "Year 2038" problem. Kernel developers are still working through the massive codebase to allow it to function past this "Unix Millenium Bug."

    The Year 2038 problem is when on 19 January 2038 that Unix systems storing time as a 32-bit integer will wrap around. Developers for years have been working on Year 2038 fixes but the kernel isn't quite tidied up yet.

  • Radeon+Ryzen CPUFreq CPU Scaling Governor Benchmarks On Linux 4.15

    Taking a break from KPTI and Retpoline benchmarks, here are some tests recently conducted with Linux 4.15 when it comes to trying out the different CPUFreq scaling governors with this latest kernel and running various games with a Radeon RX 580 Polaris graphics card.

  • VK9, the project to get Direct3D 9 applications to run with Vulkan reached another milestone

    In late December last year, the developer of the VK9 project emailed us about hitting another milestone with their project to get Direct3D 9 applications to run with Vulkan.

Kernel: Virtme, 2018 Linux Audio Miniconference and Linux Foundation Articles

  • Virtme: The kernel developers' best friend
    When working on the Linux Kernel, testing via QEMU is pretty common. Many virtual drivers have been recently merged, useful either to test the kernel core code, or your application. These virtual drivers make QEMU even more attractive.
  • 2018 Linux Audio Miniconference
    As in previous years we’re trying to organize an audio miniconference so we can get together and talk through issues, especially design decisons, face to face. This year’s event will be held on Sunday October 21st in Edinburgh, the day before ELC Europe starts there.
  • How Writing Can Expand Your Skills and Grow Your Career [Ed: Linux Foundation article]
    At the recent Open Source Summit in Vancouver, I participated in a panel discussion called How Writing can Change Your Career for the Better (Even if You don't Identify as a Writer. The panel was moderated by Rikki Endsley, Community Manager and Editor for Opensource.com, and it included VM (Vicky) Brasseur, Open Source Strategy Consultant; Alex Williams, Founder, Editor in Chief, The New Stack; and Dawn Foster, Consultant, The Scale Factory.
  • At the Crossroads of Open Source and Open Standards [Ed: Another Linux Foundation article]
    A new crop of high-value open source software projects stands ready to make a big impact in enterprise production, but structural issues like governance, IPR, and long-term maintenance plague OSS communities at every turn. Meanwhile, facing significant pressures from open source software and the industry groups that support them, standards development organizations are fighting harder than ever to retain members and publish innovative standards. What can these two vastly different philosophies learn from each other, and can they do it in time to ensure they remain relevant for the next 10 years?

Red Hat: PodCTL, Security Embargos at Red Hat and Energy Sector

  • [Podcast] PodCTL #50 – Listener Mailbag Questions
    As the community around PodCTL has grown (~8000 weekly listeners) we’ve constantly asked them to give us feedback on topics to discuss and areas where they want to learn. This week we discussed and answered a number of questions about big data and analytics, application deployments, routing security, and storage deployment models.
  • Security Embargos at Red Hat
    The software security industry uses the term Embargo to describe the period of time that a security flaw is known privately, prior to a deadline, after which time the details become known to the public. There are no concrete rules for handling embargoed security flaws, but Red Hat uses some industry standard guidelines on how we handle them. When an issue is under embargo, Red Hat cannot share information about that issue prior to it becoming public after an agreed upon deadline. It is likely that any software project will have to deal with an embargoed security flaw at some point, and this is often the case for Red Hat.
  • Transforming oil & gas: Exploration and production will reap the rewards
    Through advanced technologies based on open standards, Red Hat deliver solutions that can support oil and gas companies as they modernize their IT infrastructures and build a framework to meet market and technology challenges. Taking advantage of modern, open architectures can help oil and gas providers attract new customers and provide entry into markets where these kinds of services were technologically impossible a decade ago.
