  • There is no such thing as a static website

    A common distinction in technology for building websites is a separation between "static" and "dynamic" websites. The idea is that a "static" website always returns the same HTML/CSS/etc, whereas a "dynamic" website changes the content that the server returns depending on the request.

    This seems, at first glance, to be a pretty sharp and useful distinction, letting us easily distinguish between static and dynamic. However, I don't think it holds up to real scrutiny, and I believe that this distinction is holding us back from building better types of software that exist in the blurry space between static and dynamic.

    First off, we should look at why people care about this distinction in the first place. When looking at any sort of taxonomy, a good first question to ask is "who is this useful to, and why?"

  • Pi-hole Installation Guide

    You probably know already the concept of the Pi-hole. If not, it’s a (forwarding) DNS server that you can install on your private network at home. All your clients, including every single smartphone, tablet, laptop, and IoT devices such as smart TVs or light bulb bridges, can use this Pi-hole service as their DNS server. Now here’s the point: it not only caches DNS entries, but blocks certain queries for hostnames that are used for ads, tracking, or even malware. That is: you don’t have to use an ad- or track-blocker on your devices (which is not feasible on smart TVs or smartphone apps, etc.), but you’re blocking this kind of sites entirely. Nice approach!

    Yes, there are already some setup tutorials for the Pi-hole out there. However, it’s not only about installing the mere Pi-hole, but setting it up with your own recursive DNS server (since the default installation forwards to public DNS servers), using DNSSEC, and adding some more adlists. That’s why I am listing my installation procedure here as well. However, it’s not a complete beginners guide. You’ll need some basic Linux know-how.

    I am using a Raspberry Pi 3 B+ Rev 1.3 with Raspberry Pi OS for this setup. (While in the meantime I’m running Pi-hole on my Intel NUC with Ubuntu server.)

  • How To Add, Remove and Update Software in Linux Using Apt

    Linux has many ways to install software. We can build our own executables or use AppImage to run containerized applications. But at the heart of many Linux distros is a package management system, which for Debian based systems, such as the Raspberry Pi and Ubuntu, is Apt.

    Apt, the Advanced Packaging Tool is a command line application which handles the installation, categorization and removal of applications and their dependencies from the software repositories. Apt is the heart of Debian systems and the lessons learnt are applicable from the $35 Raspberry Pi to million dollar super computers. Apt is available via the Terminal and we can even administrate systems remotely using a remote connection such as SSH.

    A command line tool may seem daunting but here we detail the most common commands that you will use to keep your system updated with the latest software.

  • 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.
