That document has just been merged into the mainline as part of the 5.18 merge window.

      • Make Use Of ☛ The 7 Best Networking Tools That Replace the Deprecated net-tools on Linux

        The net-tools package hasn't been updated by the developers in a long time. Luckily, you can use these new and better networking tools on Linux.

        Linux comes with a host of networking tools for managing both large-scale and small-scale network infrastructure. For a long time, net-tools have been the default networking tools of choice, but they have now been replaced by iproute2 tools.

        This guide will look at some important networking tools meant to replace the deprecated net-tools. Most modern versions of Linux come with the new iproute2 tools by default.

        Here are some of the new iproute2 networking tools that replaced the old and deprecated net-tools on Linux.

      • ByteXD ☛ How to Install Budgie Desktop in Ubuntu 20.04/22.04 - ByteXD

        Budgie Desktop is a desktop environment that is based on GNOME. It is designed to be simple, easy to use, lightweight and fast. It is also one of the few desktop environments that is designed specifically for the Solus operating system. Budgie’s philosophy is to provide a simple, easy to use desktop environment that is visually appealing and user-friendly.

        It was started in 2013 and is developed by Ikey Doherty, Joshua Strobl and Solus project team as a project to replace the GNOME 2 desktop environment. It was originally designed for the Solus Linux operating system, but it can now be used on any Linux distribution. The name “Budgie” comes from the Budgie bird.

        Budgie Desktop is a good choice for users who are looking for a desktop environment that is similar to GNOME, but with a few extra features and a more modern look and feel.

        Some of its shortcomings are that it is not as customizable as other desktop environments, and it does not have as many features as other desktop environments.

        Ubuntu Budgie is a community developed Ubuntu flavor built around the Budgie desktop environment. The goal is to integrate the simplicity and elegance of Budgie with the full power of Ubuntu.

      • How to find ip address in Linux - TechStory

        Whether we realise it or not, we all use the Internet Protocol (IP) on a daily basis. When you type a website address or a search term into your web browser, for example, it looks up the IP address of that URL (or of a search engine) and then loads the website.

      • Linux Journal ☛ Simulating Host Identity Protocol-Based Virtual Private LAN Service Using Mininet Framework | Linux Journal

        Virtual Private LAN Services (VPLS) provide means for building Layer 2 communication on top of existing IP networks. VPLS can be built using various approaches. However, when building a production-grade VPLS solution one needs to have a clear picture of how such aspects as security, mobility, and L2 issues will be solved.

        In this short article, we will demonstrate how to build the VPLS using Host Identity Protocol (HIP). Since our goal is not to build a production-grade implementation of HIP-switches, we will only demonstrate proof of a concept solution that uses Mininet – a framework for simulating L2 and L3 networks. It is worth mentioning that the code we have produced can be also deployed (under certain conditions; for example, our HIP implementation does not feature the NAT traversal mechanisms and does not yet provide an L2 loop prevention mechanism) on the real hardware.

        While building HIP-switches (the switches that are deployed at the border of a network) we came across several challenges. First, we understood that HIP-switches need to support the IEEE 802.1D protocol (or its modification - this really depends on the version of the protocol supported by the switches) to avoid L2 loops in the network. This problem was initially addressed in the relevant IETF draft. Second, there were certain issues with MTU and the inability of the Linux kernel to deliver IP packets when those are fragmented in user space and injected into the network stack using raw sockets. And finally, it took us some time to repackage the existing implementation of HIP protocol as a library, so that it will be agnostic about low-level networking (such as raw sockets, etc.). Since the implementation of the IEEE 802.1D protocol for our HIP-switches is still ongoing, we will demonstrate the usage of HIP-based VPLS using loop-free L2 topology.

        • Red Hat Official ☛ How Red Hat and NVIDIA are helping to accelerate enterprise AI projects with GPUs, DPUs and MLOps

          Artificial Intelligence (AI) is transforming how modern enterprises are doing business and pressing organizations to increasingly integrate AI, along with its Machine Learning (ML) and Deep Learning (DL) capabilities, into cloud-native applications to deliver more insight and value for their customers and employees. In fact, the recent 2022 Red Hat Global Outlook report found that AI/ML was the top emerging technology workload most likely to be considered in the next 12 months, with 53% of the IT leaders surveyed ranking it the top priority.

          To help organizations more quickly and easily develop AI/ML-powered cloud-native applications and deploy them into production, Red Hat is supportingt OpenShift on several new infrastructure footprints. OpenShift offers a ubiquitous infrastructure to enable machine learning operations (MLOps) at scale, spanning NVIDIA DGX systems, to Arm-based instances in the public cloud to a new class of datacenter hardware called NVIDIA BlueField-2 data processing units (DPUs).

        • Red Hat OpenShift 4.10 Adds NVIDIA AI Enterprise 2.0 Certification

          Red Hat has announced new certifications and capabilities for Red Hat OpenShift aimed at accelerating the delivery of intelligent applications across the hybrid cloud. These enhancements, including the certification of Red Hat OpenShift with NVIDIA AI Enterprise 2.0, as well as the general availability of Red Hat OpenShift 4.10, are intended to help organizations deploy, manage and scale artificial intelligence (AI) workloads with confidence.

          While AI is transforming how enterprises do business, operationalizing an AI infrastructure can be complex and time- and resource-intensive. To help accelerate the process, Red Hat OpenShift is now certified and supported with the NVIDIA AI Enterprise 2.0 software suite, an end-to-end, cloud-native suite of AI and data analytics software that runs on mainstream, NVIDIA-Certified Systems.

        • 9to5Linux ☛ Xubuntu’s Default Xfce Desktop Theme Greybird Gets Initial Support for GTK4

          Almost six months in development, Greybird 3.23.0 is here to introduce initial support for GTK4 and libhandy in an attempt to make the popular Xfce theme, which is used by default in recent Xubuntu releases, more modern and keep it up with the times. GTK4 support means that Grebird will play nice with recent GTK4 apps.

          For those not familiar with libhandy, it’s a library used for creating mobile versions of GTK and GNOME apps, so Greybird getting libhandy support could mean that it might see a version of the Xfce desktop environment on mobile operating systems like ExpidusOS, which is still in very alpha stage.

          • Oracle Announces Java 18

            Oracle today announced the availability of Java 18, the latest version of the world’s number one programming language and development platform. Java 18 (Oracle JDK 18) delivers thousands of performance, stability, and security improvements, including nine enhancements to the platform that will further improve developer productivity.

            The latest Java Development Kit (JDK) provides updates and improvements with nine JDK Enhancement Proposals (JEPs). These include the capability to add Code Snippets in Java API Documentation (JEP 413), which simplifies the addition of sample source code in API documentation, and Simple Web Server (JEP 408) for prototyping and testing. Developers can explore two incubating modules: the Vector API (JEP 417) and the Foreign Function and Memory API (JEP 419), as well as a preview feature: Pattern Matching for Switch (JEP 420).

            “The release of Java 18 demonstrates Oracle’s continued commitment to provide enterprises and developers faster access to enhancements with the six-month feature release cadence,” said Georges Saab, Vice President of Development, Java Platform Group, Oracle. “We continue to make technical investments that improve the performance, stability, and security of the Java SE Platform implementations, as well as the Java Development Kit.”

In order to circumvent that somewhat and get to axe people from anywhere across the organisation my employer has decided to offer very generous severance packages to a select 20 or so per cent of employees.
