  1. How to set up the Pretty Hostname - Unixcop the Unix / Linux the admins deams

    A pretty hostname avoids most of the limitations of other hostname types, giving users more freedom when naming their systems.

    In this tutorial, we will show you how to set up a pretty hostname for a Linux system in two different methods.

  2. How to install and use SAR command (to Monitor system Performance) in Linux - Unixcop the Unix / Linux the admins deams

    System Activity Report (sar) is a Unix System V-derived system monitor command used to report on various system loads, including CPU activity, memory/paging, interrupts, device load, network and swap space utilization. Sar uses /proc filesystem for gathering information.

    In this tutorial, We will show you how to install and use SAR command in Linux.

  3. How to Ping a Port Number in Linux - Unixcop the Unix / Linux the admins deams

    Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It is available for virtually all operating systems that have networking capability, including most embedded network administration software.

    Port numbers belong to transport layer protocols, such as TCP and UDP. Port numbers help identify where an Internet or other network message forwarded when it arrives.

    So Pinging ports is one of the most effective troubleshooting technique in order to see if a service is alive or not.

    In this tutorial, we will show you how to ping a port in Linux using three different tools.

  6. How to Install Zoom on Linux - Make Tech Easier

    “Can I install Zoom on Linux?” was the first question that came to mind when my bosses informed me that we would be working from home and using Zoom for remote meetings and one-on-one interactions with fellow employees and clients. The answer to that first question is yes, you can install Zoom on Linux. Let’s look at how to download and install the Zoom client on four different Linux distributions: Fedora, Manjaro (Arch), OpenSUSE, and Ubuntu/Debian.

  7. How to upgrade from Fedora 34 to Fedora 35 | FOSS Linux

    The official stable release of Fedora Workstation 35 was made available for download on November 2, 2021, after being pushed back to resolve some outstanding bugs. You can now install or upgrade to Fedora 35 Desktop, Fedora cloud, Fedora Servers, or any spin or labs that come with any new release cycle.

    If you prefer a fresh installation, you will have to download the latest ISO, create a bootable USB and perform a fresh install. I prefer an upgrade of the Fedora 34 system to Fedora 35. An upgrade will retain any existing files and all installed applications.

    The article is a step-by-step guide on how to upgrade to Fedora 35 via GUI (GNOME software) and the CLI method.

  • Practicing lean data is a journey that can start anywhere - Open Policy & Advocacy

    “It’s not about the destination, but about the journey.” I’m sure data and privacy are the furthest from your mind when you hear this popular saying. However, after a year of virtually sharing Mozilla’s Lean Data Practices (LDP), I’ve realized this quote perfectly describes privacy, LDP, and the process that stakeholders work through as they apply the principles to their projects, products, and policies. [...] There is an appetite to understand how we as consumers can hold companies accountable. One of the biggest surprises for me came when I would field questions at the end of a presentation, and people would ask about their rights as consumers and how they can hold companies accountable. For example, people wanted to understand their rights and recourse options if companies contacted them without permission, didn’t honor their unsubscribe requests, or did something else frustrating. I teach LDP for individuals to apply it in a business context, but we are all also consumers and customers. LDP can help us better understand how our own data should be handled and improve our understanding of what organizations are doing. We can then remember how we feel about certain situations and then ensure we are doing things in a more consumer-friendly way within our organizations. Lean Data Practices is a journey. For many there won’t be an ultimate destination because it is an iterative process. If you try to apply all the principles across your entire organization at once, you will find yourself overwhelmed and likely unsuccessful. To maximize your chance of success, my advice — which is the same advice we give when we present — is to just start somewhere. Choose one aspect of your business and focus on that, one pillar at a time. Once you’ve successfully applied the principles, go to a different business unit and do the same. Remember to review and adapt as products and business needs (or data!) change as well. You may likely never reach your destination, but you will see your company improve in its practices along the way.

  • Tor vs. VPN: Is One Better than the Other?

    Tor and VPN have unique ways to ensure user privacy on the Internet. They’re fundamentally very different yet have many similar aims. Due to the overlap in features, you may be weighing the pros and cons of using one over the other. Or maybe they can be treated equally but with separate purposes. This guide digs into everything you need to know about which software should be used for more Internet anonymity.

Intel Core i9 12900K P-State Governor Performance On Linux Review

Since Intel's Alder Lake launch one of the test requests to come in a few times has been about the Intel P-State CPU frequency scaling driver and how its performance differs with the various governor choices available for altering the CPU frequency scaling behavior. Now that Linux 5.16 stable is out and running in good shape on Alder Lake, here are some Core i9 12900K benchmarks looking at various CPU frequency scaling choices and their impact on raw performance as well as CPU thermals and power consumption. With Alder Lake having seen fixes in Linux 5.16 as well as ADL-S graphics being enabled by default on this new kernel, it's a good target for carrying out the P-State testing. The main reader inquiry has obviously been about how how well these new Intel hybrid processors perform if moving from P-State "powersave" as is often the default governor on most distributions to instead using the "performance" governor that tends to keep the CPU in its higher performance states more aggressively than powersave.
