  • 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.

First Release Candidate of Linux 5.3

  • Linux 5.3-rc1
    It's been two weeks, and the merge window is over, and Linux 5.3-rc1
    is tagged and pushed out.
    
    This is a pretty big release, judging by the commit count. Not the
    biggest ever (that honor still goes to 4.9-rc1, which was
    exceptionally big), and we've had a couple of comparable ones (4.12,
    4.15 and 4.19 were also big merge windows), but it's definitely up
    there.
    
    The merge window also started out pretty painfully, with me hitting a
    couple of bugs in the first couple of days. That's never a good sign,
    since I don't tend to do anything particularly odd, and if I hit bugs
    it means code wasn't tested well enough. In one case it was due to me
    using a simplified configuration that hadn't been tested, and caused
    an odd issue to show up - it happens. But in the other case, it really
    was code that was too recent and too rough and hadn't baked enough.
    The first got fixed, the second just got reverted.
    
    Anyway, despite the rocky start, and the big size, things mostly
    smoothed out towards the end of the merge window. And there's a lot to
    like in 5.3. Too much to do the shortlog with individual commits, of
    course, so appended is the usual "mergelog" of people I merged from
    and a one-liner very high-level "what got merged". For more detail,
    you should go check the git tree.
    
    As always: the people credited below are just the people I pull from,
    there's about 1600 individual developers (for 12500+ non-merge
    commits) in this merge window.
    
    Go test,

  • Linux 5.3-rc1 Debuts As "A Pretty Big Release"

    Just as expected, Linus Torvalds this afternoon issued the first release candidate of the forthcoming Linux 5.3 kernel. It's just not us that have been quite eager for Linux 5.3 and its changes. Torvalds acknowledged in the 5.3-rc1 announcement that this kernel is indeed a big one: "This is a pretty big release, judging by the commit count. Not the biggest ever (that honor still goes to 4.9-rc1, which was exceptionally big), and we've had a couple of comparable ones (4.12, 4.15 and 4.19 were also big merge windows), but it's definitely up there."

  • The New Features & Improvements Of The Linux 5.3 Kernel

  • Container use cases explained in depth

  • Set_env.py

    A good practice when writing complicated software is to put in lots of debugging code. This might be extra logging, or special modes that tweak the behavior to be more understandable, or switches to turn off some aspect of your test suite so you can focus on the part you care about at the moment. But how do you control that debugging code? Where are the on/off switches? You don’t want to clutter your real UI with controls. A convenient option is environment variables: you can access them simply in the code, your shell has ways to turn them on and off at a variety of scopes, and they are invisible to your users. Though if they are invisible to your users, they are also invisible to you! How do you remember what exotic options you’ve coded into your program, and how do you easily see what is set, and change what is set?

  • RPushbullet 0.3.2

    A new release 0.3.2 of the RPushbullet package is now on CRAN. RPushbullet is interfacing the neat Pushbullet service for inter-device messaging, communication, and more. It lets you easily send alerts like the one to the left to your browser, phone, tablet, … – or all at once. This is the first new release in almost 2 1/2 years, and it once again benefits greatly from contributed pull requests by Colin (twice !) and Chan-Yub – see below for details.

  • A Makefile for your Go project (2019)

    My most loathed feature of Go was the mandatory use of GOPATH: I do not want to put my own code next to its dependencies. I was not alone and people devised tools or crafted their own Makefile to avoid organizing their code around GOPATH.

  • Writing sustainable Python scripts

    Python is a great language to write a standalone script. Getting to the result can be a matter of a dozen to a few hundred lines of code and, moments later, you can forget about it and focus on your next task. Six months later, a co-worker asks you why the script fails and you don’t have a clue: no documentation, hard-coded parameters, nothing logged during the execution and no sensible tests to figure out what may go wrong. Turning a “quick-and-dirty” Python script into a sustainable version, which will be easy to use, understand and support by your co-workers and your future self, only takes some moderate effort.

The Status of Fractional Scaling (HiDPI) Between Windows & Linux

There’s a special type of displays commonly called “HiDPI“, which means that the number of pixels in the screen is doubled (vertically and horizontally), making everything drawn on the screen look sharper and better. One of the most common examples of HiDPI are Apple’s Retina displays, which do come with their desktops and laptops. However, one issue with HiDPI is that the default screen resolutions are too small to be displayed on them, so we need what’s called as “scaling”; Which is simply also doubling the drawn pixels from the OS side so that they can match that of the display. Otherwise, displaying a 400×400 program window on a 3840×2160 display will give a very horrible user experience, so the OS will need to scale that window (and everything) by a factor of 2x, to make it 800×800, which would make it better. Fractional scaling is the process of doing the previous work, but by using fractional scaling numbers (E.g 1.25, 1.4, 1.75.. etc), so that they can be customized better according to the user’s setup and needs. Now where’s the issue, you may ask? Windows operating system has been supporting such kind of displays natively for a very long time, but Linux distributions do lack a lot of things in this field. There are many drawbacks, issues and other things to consider. This article will take you in a tour about that. Read more Also: Vulkan 1.1.116 Published With Subgroup Size Control Extension
