  • How To Install VirtualBox on Manjaro 20 - idroot

    In this tutorial, we will show you how to install VirtualBox on Manjaro 20. For those of you who didn’t know, VirtualBox is open-source cross-platform virtualization software for x86 architecture and this software allows you to create and run guest operating systems (“virtual machines”) such as Linux and Windows on top of the host operating system.

    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 through the step-by-step installation of VirtualBox on a Manjaro 20 (Nibia).

  • How to Install and Configure Nagios in Ubuntu Linux

    Nagios is a robust continuous and real-time monitoring tool to monitor your organizations and servers. Nagios can be installed on Ubuntu Linux desktop and server system for both manual and automatic monitoring. If you have a company that runs server-level operations, you probably need continuous integration (CI) and continuous delivery (CD) tools to make your production rate faster and better.

    Nagios can help you to grow your company by providing better analysis. However, if you have a software production company, you can look at the Jenkins server features. Jenkins and Nagios both can be used in Linux through a plugin arrangement.

  • Linux Filesystem Error: Transaction failed when using LXD - nixCraft

    I am a big fan of LXD, a next-generation Linux system container manager and default on Ubuntu. It allows me to run desktop apps or server apps in an isolated environment. Ubuntu provides LXD with robust security in mind. However, this might lead to undesired side effects, such as individual packages under OpenSUSE or CentOS Linux may not be updated. One such package is the filesystem package. Let us see how to fix Error: Transaction failed when you try to update filesystem package under CentOS, OpenSUSE, and other Linux containers running under LXD.

  • Making 12factor Elixir/Phoenix releases

    Elixir had a bad reputation for its deployment story due to the complex tooling and compile-time configuration preference. That is history now as we can easily make Elixir v1.11 releases with the runtime configuration to adhere to the 12factor style of deployment.

    If you don’t know what 12factor is, it’s a document made at Heroku with recommendations how to design your applications. Although the purpose was most likely about stirring people into making applications that would run smoothly on the Heroku platform, it’s a quite sensible set of recommendations.

    I don’t think you have to adhere to 12factor at all costs, but some points make sense. This post is namely about section III., which recommends storing configuration in an environment. Something a bit problematic in Elixir before, but something I always wanted.

    Sections on dependencies and logs are also relevant, while sections on stateless processes and concurrency might not apply to us as Beam has its own lightweight stateful processes. However, you can decide to keep Elixir nodes stateless and use something like Redis.

  • How to Use Scanline Sync and Cap FPS In RivaTuner - Make Tech Easier

    While RivaTuner Statistics Server (RTSS) is most well-known for being bundled with MSI Afterburner and used for monitoring and overclocking GPUs, RTSS actually has some use separate from Afterburner. Here, we discuss those functions and teach you how to use them to cap your FPS (frame per second) or enable Scanline Sync.

    [...]

    FPS in this context refers to Frames Per Second, and on PCs where you have an FPS exceeding your refresh rate (such as 100 FPS on a 60 HZ panel), you’re much more prone to screen tearing and highly-variable FPS. Both of these can be visually disorienting and a competitive disadvantage, but the seemingly only way to fix it in most games is to enable some form of V-Sync, which is much more visually consistent but adds a lot more input latency.

    Using an FPS cap, you can set your in-game framerate to just at or just under your screen refresh rate. If the game you’re playing offers an FPS cap, chances are high that you’ll want to use that cap instead of RivaTuner’s, but if you want to learn how to use RivaTuner’s for universal application, keep reading.

  • The Linux Kernel & GNOME Desktop Preparing For Privacy Screen Support - Phoronix

    Over the past year there has been an uptick in Linux developers from different vendors working on laptop privacy screen support under Linux. When it comes to the support with newer Lenovo ThinkPad laptops, it looks like that kernel support could soon land and the GNOME desktop is already preparing to support this feature.  Select Lenovo laptops in recent years have offered a built-in "Privacy Guard ePrivacy Filter" for limiting the viewing angles of the laptop with a simple push of a button on the ThinkPad laptops. While the effectiveness of the "ePrivacy" feature is debatable in its current form and with the current work from home craze / limited travel making the feature less pressing at the moment, the Linux support is coming together.

  • Gigabyte Motherboard WMI Temperature Driver Queued Ahead Of Linux 5.13 - Phoronix

    Earlier this month I reported on a WMI temperature driver for Gigabyte motherboards being worked on by an independent developer. That "gigabyte-wmi" driver is now slated for inclusion in the upcoming Linux 5.13 cycle.  This driver exposes the Windows Management Instrumentation (WMI) temperature sensors under Linux. When writing originally about this new driver it was only tested on a Gigabyte X570 Aorus Pro WiFi motherboard but since then has been tested and confirmed to also be working on the likes of the Gigabyte's B550M DS3H, B550 Gaming X V2, and Z390 I Aorus Pro WiFi motherboards as well.

  • A New Gigabyte Motherboard WMI Temperature Driver Will Likely Arrive In Linux 5.13

    Linux users with newer Gigabyte and ASUS motherboards for AMD processors have to compile a out-of-tree version of the it87 to get hardware sensors and fan control working, and sensor support for the very newest motherboards is a shot in the dark even if you do that. That may change for Gigabyte-users with Linux 5.13 as a new, Gigabyte-specific WMI driver has been merged into the Linux kernels platform drivers git tree. It will likely be merged into Linux 5.13 when the merge window opens.

  • Rust Support In The Linux Kernel Undergoing Another Round Of Discussions

    Last month the initial infrastructure for allowing the Rust programming language to be used within the Linux kernel landed in the Linux-Next tree for more widespread testing ahead of its possible inclusion in the mainline kernel. Now a "request for comments" has been started again on the kernel mailing list around the prospects of Rust code for the Linux kernel.  Kernel developer Miguel Ojeda started this latest "RFC" proposal on the Linux kernel mailing list. The lengthy mailing list post outlines the beliefs of the involved developers over adding Rust code to the kernel, the benefits like improved memory safety, and more.

  • Google Supports Getting Rust Into The Linux Kernel

    It should come as little surprise -- especially given the recent news of Google allowing Rust to be used for Android system-level code -- but engineers at the search giant are in support of Rust code being used within the mainline Linux kernel.  In addition to yesterday's Rust RFC for the Linux kernel and that discussion still taking place on the Linux Kernel Mailing List, Google engineers on the Google Security Blog have penned their own piece on the matter.
