  • 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.

  • Creating Text | Inkscape

    This is the fourth of Inkscape For Students the series after we learned about Fonts before, now we will learn how to create text. When doing design with computer, you will find text is an important part -- you will earn so much by just learning text alone. This is why this series invite you to practice firstly with text before shapes and colors. Now let's learn and practice!

  • 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.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
