  • A decade of dotfiles

    My first commit to my dotfiles repository was ten years ago. Here are a few things I’ve learned about maintaining a system configuration in that time.

  • John Goerzen: Fast, Ordered Unixy Queues over NNCP and Syncthing with Filespooler

    It seems that lately I’ve written several shell implementations of a simple queue that enforces ordered execution of jobs that may arrive out of order. After writing this for the nth time in bash, I decided it was time to do it properly. But first, a word on the why of it all.

  • How to Install PHP 8.1 on AlmaLinux 9
  • How to Delete All Files in a Directory Except Few

    File deletion is an important yet sensitive aspect of Linux administration. The Linux commands behind file deletion operations help us get rid of files we do not need.

    There is usually a high chance that the files we wish to delete reside in a single folder or directory. If we did not need all these files; once we navigate to that directory, it would be easier to get rid of them with a simple rm command implementation.

  • How to Install Psensor Temperature Monitoring Application on Ubuntu 20.04

  • Installing Nginx on OpenBSD 7.1

    Nginx is a web server created with a focus on performance, high concurrency and low resource usage. It serves the majority of the top websites. Whilst this is mostly due to its performance, it’s also relatively easy to get started with.

    By default, Nginx deals with web requests asynchronously i.e. a single nginx process can serve multiple requests concurrently. However, because of this design Nginx, as compared to web servers like Apache, can’t embed server side programming languages like PHP into its own process. This means those tasks are to be handled by completely separate processes and then reverse proxied back to the clients via Nginx. Therefore, at its core, Nginx is actually just a reverse proxy.

    In this article, we’re going to go through the process of compiling and installing Nginx through source. While installation through the package manager is fairly easy, we do not get as much control over the Nginx binary as we get by compiling from source. I have chosen OpenBSD for it serves very well as a secure server operating system.

  • How To Install RPM Fusion on Fedora 34/35/36

    RPM Fusion is a software repository, providing add-on packages for Fedora Linux. It was born as a merge of the older repositories Livna, Dribble and Freshrpms. They distributed software that Fedora will not, either because it does not meet Fedora’s definition of free software, or because distribution of that software may violate US law.

    The RPM Fusion repository comes in two variants, Free and Non-Free. The free repository contains a free version of the software that is open source and non-free, which have mostly almost all free software but are closed source and mainly proprietary.

  • How To Install Bareos Backup Solution on Fedora 36

    In this article, we will show you how to install Bareos backup solution on Fedora 36

    Bareos (Backup Archiving Recovery Open Sourced) is a backup software, originally forked from the Bacula project. It is network-based, multi-client and very flexible with an architecture oriented towards scalability. Thus the learning curve might be considered somewhat steep. The project is backed by the commercial company Bareos GmbH & Co. KG, based in Germany.

  • How to speed Up dnf Package Manager In Fedora, RHEL and CentOS

    DNF or Dandified YUM is the next-generation version of the Yellowdog Updater, Modified (yum), a package manager for .rpm-based Linux distributions. DNF was introduced in Fedora 18 in 2013, it has been the default package manager since Fedora 22 in 2015, Red Hat Enterprise Linux 8 , and OpenMandriva; and also an alternative package manager for Mageia.

    Perceived deficiencies of yum (which DNF is intended to address) include poor performance, high memory usage, and the slowness of its iterative dependency resolution. DNF uses libsolv, an external dependency resolver.

  • 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.
