  • OPNFV Hunter Delivers Test Tools, CI/CD Framework to Enable Common NFVI for Verifying VNFs

    LF Networking (LFN), which facilitates collaboration and operational excellence across open networking projects, today announced the availability of OPNFV ?Hunter,? the platform?s eighth release. Hunter advances OPNFV?s system level integration, deployment, and testing to collaboratively build a common industry Network Functions Virtualization Infrastructure (NFVI) that will reduce Communication Service Provider (CSP) and Virtual Network Function (VNF) vendor efforts to verify VNFs against different NFVI platforms.

    Open Platform for NFV (OPNFV) is a project and community that facilitates a common NFVI, continuous integration (CI) with upstream projects, stand-alone testing toolsets, and a compliance and verification program for industry-wide testing and integration to accelerate the transformation of enterprise and service provider networks.  

    ?The latest OPNFV release sets the stage for a real turning point in the maturity of the platform,? said Heather Kirksey, vice president, Community & Ecosystem Development, the Linux Foundation. ?With continued evolution in areas of testing, verification, and CI/CD, OPNFV is on its way to enable a common NFVI stack that will meet the needs of operators. We are working  in collaboration with both global operators as well as the GSMA, and I am incredibly excited to see the community work to provide the resources needed to accelerate network transformation across the ecosystem.?

  • Glusterfs vs. Ceph: Which Wins the Storage War?

    Storing data at scale isn?t like saving a file on your hard drive. It requires a software manager to keep track of all the bits that make up your company?s files. That?s where distributed storage management packages like Ceph and Gluster come into place.

    Ceph and Gluster are both systems used for managing distributed storage. Both are considered software-defined storage, meaning they?re largely hardware-agnostic. They organize the bits that make up your data using their own underlying infrastructure, which is what defines this choice: what underlying framework do you want supporting your data?

    That?s a decision you want to make based on the type of data you?re storing, how that data is accessed, and where that data lives. Ceph and GlusterFS are both good choices, but their ideal applications are subtly different.

  • Developing Kubernetes API Extensions And Operators - Kubebuilder Vs Operator Kit Vs Metacontroller

    As more teams adopt Kubernetes in production, specific use cases and needs have emerged that build on the core feature set of the project. Rather than attempt to fit every requirement in Kubernetes itself, the community has worked towards building an extension framework to enable developers to build support for these different scenarios. Examples of customizing Kubernetes include configuring different network or storage plugins, restricting what container images can be run inside Pods and other admission policies, or creating API extensions for automating common cluster operations. Let?s take a deeper look at the latter type of extension.

Linux Kernel and Linux Foundation Leftovers

  • Improve memset
    
    since the merge window is closing in and y'all are on a conference, I
    thought I should take another stab at it. It being something which Ingo,
    Linus and Peter have suggested in the past at least once.
    
  • An Improved Linux MEMSET Is Being Tackled For Possibly Better Performance

    Borislav Petkov has taken to improve the Linux kernel's memset function with it being an area previously criticzed by Linus Torvalds and other prominent developers. Petkov this week published his initial patch for better optimizing the memset function that is used for filling memory with a constant byte.

  • Kernel Address Space Isolation Still Baking To Limit Data Leaks From Foreshadow & Co

    In addition to the work being led by DigitalOcean on core scheduling to make Hyper Threading safer in light of security vulnerabilities, IBM and Oracle engineers continue working on Kernel Address Space Isolation to help prevent data leaks during attacks. Complementing the "Core Scheduling" work, Kernel Address Space Isolation was also talked about at this week's Linux Plumbers Conference in Lisbon, Portugal. The address space isolation work for the kernel was RFC'ed a few months ago as a feature to prevent leaking sensitive data during attacks like L1 Terminal Fault and MDS. The focus on this Kernel ASI is for pairing with hypervisors like KVM as well as being a generic address space isolation framework.

  • The Linux Kernel Is Preparing To Enable 5-Level Paging By Default

    While Intel CPUs aren't shipping with 5-level paging support, they are expected to be soon and distribution kernels are preparing to enable the kernel's functionality for this feature to extend the addressable memory supported. With that, the mainline kernel is also looking at flipping on 5-level paging by default for its default kernel configuration. Intel's Linux developers have been working for several years on the 5-level paging support for increasing the virtual/physical address space for supporting large servers with vast amounts of RAM. The 5-level paging increases the virtual address space from 256 TiB to 128 PiB and the physical address space from 64 TiB to 4 PiB. Intel's 5-level paging works by extending the size of virtual addresses to 57 bits from 48 bits.

  • Research Shows Open Source Program Offices Improve Software Practices

    Using open source software is commonplace, with only a minority of companies preferring a proprietary-first software policy. Proponents of free and open source software (FOSS) have moved to the next phases of open source adoption, widening FOSS usage within the enterprise as well as gaining the “digital transformation” benefits associated with open source and cloud native best practices. Companies, as well as FOSS advocates, are determining the best ways to promote these business goals, while at the same time keeping alive the spirit and ethos of the non-commercial communities that have embodied the open source movement for years.

Releasing Slax 9.11.0

New school year has started again and next version of Slax is here too :) this time it is 9.11.0. This release includes all bug fixes and security updates from Debian 9.11 (code name Jessie), and adds a boot parameter to disable console blanking (console blanking is disabled by default). You can get the newest version at the project's home page, there are options to purchase Slax on DVD or USB device, as well as links for free download. Surprisingly for me we skipped 9.10, I am not sure why :) I also experimented with the newly released series of Debian 10 (code name Buster) and noticed several differences which need addressing, so Slax based on Debian 10 is in progress, but not ready yet. Considering my current workload and other circumstances, it will take some more time to get it ready, few weeks at least.

  • Back from Akademy 2019 in Milan

    The last week I was in Milan with my wife Aiswarya to attend Akademy 2019, the yearly event of the KDE community. Once again it was a great experience, with lots of interesting conferences and productive BoF sessions (“Birds of a Feather”, a common name for a project meeting during a conference). On Sunday, we presented our talk “GCompris in Kerala, part 2”. First, Aiswarya told some bits of Free-Software history in Kerala, gave examples of how GCompris is used there, and explained her work to localize the new version of GCompris in Malayalam (the language of this Indian state). Then I made a quick report of what happened in GCompris the last 2 years, and talked about the things to come for our next release.

  • Akademy was a blast!

    I attended my first ever Akademy! The event was held at the University of Milano-Bicocca in Milan, Italy this year. And the experience was splendid. During the 2 day conference, I had the opportunity to talk at the Student Showcase, where all of the SoC students presented their work to the community. There were about 8 students, and everyone gave a good briefing on their project. My project this summer was with Kdenlive, the open source non linear professional video editor. I proposed to revamp one of the frequently used tools in the editor, called the Titler tool, which is used to create title clips. Title clips are video clips that contain text and/or images that are composited or appended to your video (eg: subtitles). The problem with the titler tool as it is, is that it uses QGraphicsView to describe a title clip and QGraphicsView was deprecated since the release of Qt5. This obviously leads to problems - upstream bugs crawling affecting the functionality of the tool and an overall degradation in the ease of maintenance of the codebase. Moreover, adding new features to the existing code base was no easy task and therefore, a complete revamp was something in sights of the developer community in Kdenlive for a long time now. I proposed to rework on the backend for the period of GSoC replacing the use of XML with QML and use a new rendering backend with QQuickRenderControl, along with a new MLT module to handle the QML frames. I was able to cover most of the proposed work, I seek to continue working on it and finish evolving the titler tool.
