Linux Plumbers Conference and Kernel Developments in METRICFS, FS-Cache, HWMON

  • Application Ecosystem Microconference Accepted into 2020 Linux Plumbers Conference

    We are pleased to announce that the Application Ecosystem Microconference has been accepted into the 2020 Linux Plumbers Conference!

    The Linux kernel is the foundation of the Linux systems, but it is not much use without applications that run on top of it. The application experience relies on the kernel for performance, stability and responsiveness. Plumbers is the perfect venue to have the kernel and app ecosystems under one roof to discuss and learn together and make a better application experience on the Linux platform.

  • Google Opens Patches For "METRICFS" That They Have Used Since 2012 For Telemetry Data

    The METRICFS file-system has been in use internally at Google since 2012 for exporting system statistics to their telemetry systems with around 200 statistics being exported per machine. They are now posting the METRICFS patches as open-source for review and possible upstreaming.

    A "request for comments" on METRICFS was sent out today on the Linux kernel mailing list. Their motives for now finally publishing these patches is as a result of the recent Statsfs proposal by a Red Hat engineer for a RAM-based file-system for exposing kernel statistics to user-space. METRICFS has a similar aim to Statsfs.

  • FS-Cache Rewritten But Even Its Developers Are Hesitant About Landing It For Linux 5.9

    FS-Cache provides the Linux kernel with a general purpose cache for network file-systems like NFS and AFS but also other special use-cases like ISO9660 file-systems. FS-Cache has been rewritten for better performance and reliability, among other benefits, and while it has been sent in as a pull request for Linux 5.9 even its own developers provide some caution over landing it this cycle.

    FS-Cache has seen work to "massively overhaul" it with a variety of improvements. The new and improved FS-Cache will now use async direct I/O in place of snooping for updated pages that in turn means less virtual memory overhead. The new FS-Cache implementation has simpler object management, changes to object invalidation, and a variety of other work.

  • Corsair Commander Pro Driver Sent In To Linux 5.9

    The hardware monitoring (HWMON) subsystem has a new driver that is likely to excite some enthusiasts wanting greater control over thermal monitoring and fan control for their systems.

    The previously covered Corsair Commander Pro Linux driver is now coming with Linux 5.9. The Commander Pro offers six 4-pin fan ports with PWM controls, two RGB LED channels, and four thermal sensors. An interested user/developer created this Linux driver without the support from Corsair. The thermal and fan control support is in place with this new HWMON driver while the RGB lighting controls are available from OpenRGB.

GNU/Linux in Hardware, Arduino for Amazon Surveillance

  • Jetson Nano based system can be powered over Ethernet

    Aaeon’s compact, $475 “Boxer-8222AI” embedded box runs Linux on a Jetson Nano along with 4x USB 3.1 Gen2, HDMI 2.0, RS-232, M.2, mini-PCIe, 40-pin GPIO, and 2x GbE ports, one with PoE/PD. In April, Aaeon unveiled two compact systems: the Nvidia Jetson Xavier NX-based Boxer-8251AI and similar Jetson Nano based Boxer-8221AI. At the time, the company mentioned an upcoming Boxer-8222AI, but without offering details. It has now launched the system, which runs the Ubuntu 18.04 based ACLinux 4.9 on the Jetson Nano.

  • Light[s]well is a voice-controlled custom lighting installation

    Designed by Brian Harms of NSTRMNT, Light[s]well is a beautifully crafted 4’x8′ light installation for a triple-height living room that’s voice-responsive thanks to the Arduino Alexa skill. Light[s]well is constructed out of 80/20 extrusions and fasteners, with individually addressable LED strips embedded in the channels of the structure. 74 sheets of laser-cut cardstock make up the undulating light-diffusing wave pattern. According to Harms, 30 LEDs per meter strips were used to give each gap in the cardstock two LEDs per structural metal beam, for a total of six LEDs per gap. The LEDs are controlled by a MKR1000 (via a logic level shifter) along with the Arduino IoT Cloud.

  • Red Hat Runtimes update delivers new features for Open Hybrid Cloud

    It’s that time again: the time we announce the latest updates and new features in Red Hat Runtimes. The latest release, now available, builds on the work we have done over the past year to create cloud-native, modern applications, with a focus on our work in advancing Java. Red Hat Runtimes is a part of the Red Hat Application Services portfolio and is a set of products, tools and components for developing and maintaining cloud-native applications that offers lightweight runtimes and frameworks for highly-distributed cloud architectures, such as microservices or serverless applications. We make updates on a regular basis to meet changing customer demands while providing them with the technology necessary to make business-critical decisions while remaining innovative, competitive and flexible. Check out the rest of the post to learn more about the most recent updates to Red Hat Runtimes.

  • Red Hat adopts ROLIE protocol for automated exchange of security compliance assets

    This is a primer on the implementation of the ROLIE protocol. The purpose of this report is to recommend automated processes for information exchange of various security compliance and vulnerability management assets using the ROLIE protocol and its open source implementation, Golie. [...] The ROLIE standard helps to discover and consume security content in a standard and automated way. A ROLIE implementation like the golie tool can be used by security vendors or regular users to consume vendor provided CVE content. It can be used as a way to submit checklists to benchmark validation organizations, or it can be used to host subscription-model services around security content. Have ideas on where else the ROLIE standard or the golie tool can be used or enhanced? Want to get involved in the project? Please provide your input and ideas at the GitHub project. It is very important to note that the vision of the project and tooling is to be multi-platform and multi-vendor. Contributions in any way are always and very welcomed! Note: The ROLIE standard is still in its early stages of development, and the format may change should the standard change.

  • Looking back to the future: Red Hat Enterprise Linux 7 as the OS trendsetter

    It’s hard to believe that we introduced Red Hat Enterprise Linux 7 (RHEL 7) into the market more than six years ago. RHEL 7 balanced the enterprise need for stability and compatibility with that of tangible innovation. At general availability, we believe that we dispelled the myth that the operating system is "just a commodity" and redefined the Linux operating system.

  • AI software stack inspection with Thoth and TensorFlow

    Project Thoth develops open source tools that enhance the day-to-day life of developers and data scientists. Thoth uses machine-generated knowledge to boost the performance, security, and quality of your applications using artificial intelligence (AI) through reinforcement learning (RL). This machine-learning approach is implemented in Thoth adviser (if you want to know more, click here) and it is used by Thoth integrations to provide the software stack based on user inputs. In this article, I introduce a case study—a recent inspection of a runtime issue when importing TensorFlow 2.1.0—to demonstrate the human-machine interaction between the Thoth team and Thoth components. By following the case study from start to finish, you will learn how Thoth gathers and analyzes some of the data to provide advice to its users, including bots such as Kebechet, AI-backed continuous integration pipelines, and developers using GitHub apps.

  • Fedora 33 Beta

    Today we are looking at Fedora 33 Beta. It comes fully packed with Gnome 3.38, Linux Kernel 5.68, and uses about 1.3-1.6GB ram when idling. It comes with Wayland and Btrfs File Manager by default and is a great Beta release. As seen in the video, it is not perfect yet, but I am sure that it will be fixed! Enjoy!
