  • How to find duplicate files in Linux? Help is here with the fdupes command! - Webleit.info

    Fdupes is a command line tool that allows you to find all duplicate files through the console. The advantage over using graphical tools like fslint is of course the speed. At the end of the day, there is nothing faster and more convenient than the Linux console.

    Why should we look for duplicate files in Linux?

    No matter what operating system you use sooner or later, your computer will contain many files of different sizes, and if you’re not careful enough, repeating them can cost you disk space that you need. For example, you inadvertently downloaded the same ultra HD movie with 40 giga bytes twice.

  • Install WordPress Automatically on Ubuntu 20.04 using WordOps

    WordOps is a simple tool that provides the ability to deploy WordPress sites from the command line using an optimized LEMP stack.

    The LEMP software stack consists of a group of software that describes a Linux Operating System, an Nginx web server (pronounced engine-x), a MySQL database with the dynamic processing being handled by PHP. LEMP is an acronym for Linux, Engine-x (Nginx), MySQL and PHP.

    WordOps simplifies so much of the process of installing and configuring all the packages from the LEMP stack needed to deploy a site while taking care of creating virtual hosts in Nginx, installing WordPress, and even gets you a SSL certificate.

    It also installs some components that allow you to see statistics about the server’s workload.

    In this tutorial we’ll use WordOps to quickly and easily install WordPress on an Ubuntu 20.04 machine, and we’ll check out and explain some of the extra features that WordOps offers.

  • How to Find Out When a Webpage Was Published - Make Tech Easier

    When you’re doing research on a topic, it’s vital to ensure your sources are up to date. If you’re writing an academic paper, dates of publication are often required in the citations.

    The majority of the time, getting the date is easy: simply look on the site and find the published date to find how recent it was. Things get a little more complicated when there is no date listed on the webpage. When this happens, how do you know when a webpage was published?

  • Another Piece For The Home Network Puzzle – A Return To Cisco IOS! – Jon's FOSS Blog

    I’ve missed the good old days of configuring and setting up good quality switching hardware (like the big, huge Cisco switches and routers I used to experiment on with their IOS command line interface). I recently ordered this newer, smaller Cisco switch which can also provide power to a new “prosumer” WiFi AP (no power cables needed).

  • Making environment variables accessible in front-end containers - Red Hat Developer

    When building a container for a single-page application using any modern JavaScript framework (such as Angular, React, or Vue.js), you might find that the configuration settings are different depending on where the container will run. A typical case would be the base URL for your API, which will differ depending on whether you are testing the application or deploying it into production. Developers usually solve this problem using environment variables.

    Environment variables typically work on the backend because that is where code runs. But what if your application lives in the user’s browser? There are many ways around this limitation. In some cases, you might build a server whose endpoint holds the necessary parameters. Another workaround is to use PHP to inject the environment variables as globals in the JavaScript code. Both of these options work, but it would be ideal to inject the environment variables as part of the container build process. That way, you don’t have to change the codebase, and you can still deliver the application content using a static web server like NGINX.

    This article shows you how to inject environment variables directly into your codebase as you build your container.

  • 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.
