  • Ubuntu Podcast from the UK LoCo: S14E16 – Planet Hiding Forces

    This week we’ve been playing Subnautica Below Zero, going to the pub and teaching celebrities how to D&D. We have a retrospective on our FOSS Talk Live one-button challenge.

  • Ceph for Enterprise, a shared mission.

    The group’s primary objectives are to raise wider awareness and understanding that Ceph is capable of being deployed in enterprise settings, and not just in developer orientated circles where it currently sees significant uptake (for example, according to the 2020 Openstack User Survey 74% of deployments are using Ceph for their block storage needs). The wider storage market is awash of options, both traditional hardware and more modern software-defined solutions. The desire of the group is to ensure that Ceph makes it into storage decision makers’ minds as a production-proven open-source powered alternative to typical proprietary options.

    Over the coming months, the Market Development Group will lead various educational efforts such as the publication of vendor-agnostic case studies, and use case analysis on the refreshed ceph.io website, as well as the creation of a speakers bureau, where requests can be made for Ceph community experts to share their experiences, and also by providing greater visibility at future in-person and virtual events.

  • Linux Mint 20.1 Installation, Review, and Customization

    Linux Mint is arguably one of the easiest and most user-friendly Linux-based operating systems to come by in the Linux world, and while it might be second to Ubuntu in popularity, it remains the favorite of a large majority of Linux users around the globe.

    Why? It’s easy; Linux Mint is essential “Ubuntu done right”. While the latter might not be bad in its own right, it is no news that the stability and flexibility the former offers are unmatched by Ubuntu.

    Linux Mint developers have taken the Ubuntu code, refined and made it into what is one of the world’s most reliable systems. And with every new iteration of Linux Mint is a much more refined software that continues to trump over Ubuntu.

  • FreeBSD Performance Observability

    By observability, we mean the ability to observe what is happening on a live system, and in many cases, to alter the behavior of that system in real-time. While there is a myriad of performance analysis tools available for purchase, you cannot understate the value of tools that are specifically built for and with an operating system: tools which understand and are built into the operating system’s kernel structures.

    Pretty much everything a FreeBSD system does, right down to the system-call level, is tracked. Each utility on the system gathers what it needs from this pool of information: for example, this information is queried when you run ifconfig or zpool status. You too can gather the information you need in order to get the most out of your system, determine your operational baselines, and find and resolve performance bottlenecks.

  • GSoC 2021 · Part II - Tracking windows and monitoring files

    Picking up where I left off…

    In the last post, I mentioned that I will be working on Implementing active resource management in GNOME. In this post I’ll be walking you through what I’ve done so far, things I have learned and what I’ll be working on next.

    What I’ve done so far

    My first task was to track the active or currently open window in gnome-shell and allocate more CPU weight to it. After discussing with my mentors we decided that building an extension for this will be easier so I built an extension which on getting notified when the focus-window has changed calls a DBus method provided by systemd to set the unit’s properties.

  • AMDVLK 2021.Q2.6 Vulkan Driver Released - Removes Pre-Polaris / Pre-Raven Support - Phoronix

    Following the announcement this week that AMD is dropping pre-Polaris GPU support (or pre-Raven Ridge support for APUs) from their mainline Radeon Software driver on Windows, the AMDVLK open-source Vulkan driver has also now similarly discontinued that older GPU support.

    AMDVLK 2021.Q2.6 was released today as their official open-source AMD Vulkan driver. With AMDVLK sharing sources to their proprietary Vulkan driver on Linux and Windows, to little surprise this driver is doing away with the pre-Polaris dGPU and pre-Raven APU support. So moving forward only the newer Radeon graphics are supported by this Vulkan driver, aligned with what is supported by Radeon Software on Windows.

  • Amazon is acquiring a podcast hosting and monetization platform

    Amazon Music is getting more serious about its podcast endeavors. Today, the company announced that it’s acquiring Art19, a major podcast hosting and monetization platform for an undisclosed sum. This means Amazon will now have a hand in hosting podcasters’ shows as well as selling ads against them because Art19 operates an ad marketplace that targets and inserts ads into programming. An Amazon Music spokesperson says nothing will immediately change on the Art19 platform.

  • Windows 11 Makes Your Hardware Obsolete, Use Linux Instead!

    The hardware should have a TPM chip, which may not be the case for some PC builds or laptops. Fortunately, it is not all bad, you may just need to enable it from your BIOS settings including the Secure Boot support, to make your PC eligible. There’s a guide on PCGamer to help you with that.

    Technically, processors older than Intel 8th gen and Ryzen 3000 series are not officially supported as per Microsoft’s official documentations (AMD | Intel).

    However, there are a sound number of systems that may not have the support for it. So, what do you do?

    Easy, switch to Linux in 2021 before Windows 10 no longer receives updates. This year, it makes more sense than ever for you to try Linux for your personal computer!

  • Ransom notes [iophk: Windows TCO]

    The question is how, and none of the choices are very good.

    You could require the immediate disclosure of ransoms. You could ban paying ransoms outright. You could ban cryptocurrency, which is how most ransoms are paid. You could increase regulation around cryptocurrency and perhaps ban certain kinds of exchanges or transactions. You could try being better friends with Vladimir Putin, in the hopes that he might sacrifice some threat actors. Your Department of Defense has also probably come up with some separate terrible ideas, which I am frightened even to contemplate.

    Every choice here hurts, at least in the short term. But let’s go through them.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
