  • Bye CUPS: Printing with netcat

    I had to read this several times. WTF. Use netcat? Surely I was missing some wizardry in the FreeBSD kernel that configured a network printer as some local network target aliased to netlaser, which handled all the printing magic for me. But how? Years of arbitrarily picking from a list of similarly named print drivers in CUPS prevented my brain from accepting what was written. I was confused. After trying to decipher the other sections in the document, I decided I would go for it.

    It. Just. Prints.

  • Gentle Guide to Get Started With tmux

    You ended up here probably because you are looking to level up your command line skills. And that’s fine, it is the exact same reason I am writing this blog post. Since I began learning how to program, I’ve been a terminal dweller, and it’s been great. I always feel at home when I log into my shell. Today, our terminal experience will feel even better. We will level up our knowledge and our toolbelt with a great tool called tmux.

  • How to make your home Shiny or Rstudio Server accessible from the public internet

    You have installed Shiny and/or RStudio server in your home computer and it works great as long as you are connected to your local network, however, you can’t access it from other locations, What can you do?

    The solution is to expose your server to the public internet by forwarding incoming traffic to the corresponding port in your server. Now, I’m not going to lie to you telling you that this article is going to give you detailed instructions on how to do it with your specific router because it would be virtually impossible, each router brand (an even model) has a different management interface, I can only give you the required steps along with an example using the router I have at home, although, generally speaking, the procedure involves the same steps regardless of the specific router model you have, so with a little effort on your part you should be able to figure out how to make it work with your own router.

  • B-Trees: More Than I Thought I'd Want to Know

    Recently, I’ve been reading through the excellent Database Internals (Alex Petrov, 2019). The first half of the book is dedicated to the implementation of database storage engines – the subsystem(s) of a DBMS that handles long-term persistence of data. A surprising amount of this section discusses the implementation and optimization of various B-Tree data structures.

  • 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.
