  • Some things on ZFS (on Linux) per-dataset basic IO statistics

    Sufficiently recent versions of OpenZFS on Linux have not just performance statistics for overall pool IO (also), but some additional per-dataset IO statistics. Conveniently, these IO statistics are exposed through the Prometheus host agent, so if you're using Prometheus (as we are), so you don't have to write something to collect and manipulate them yourself. However, what these statistics actually mean is a little bit underexplained.

  • How To Install VSCodium on Ubuntu 20.04 LTS [Ed: But this is still helping Microsoft monopoly and should thus be discouraged]

    In this tutorial, we will show you how to install VSCodium on Ubuntu 20.04 LTS. For those of you who didn’t know, VSCodium is an open-source, free clone of Microsoft’s Visual Studio Code. It’s a perfect app to set up if you love the look of VSCode, but wish it were open-source. It is available not only for Windows, Mac, and as well as for Linux.

    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 the VSCodium on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

  • How to Download Ubuntu via Torrent [Absolute Beginner’s Tip]

    Downloading Ubuntu is pretty straightforward. You go to its official website. Click on the desktop download section, select the appropriate Ubuntu version and hit the download button.

    Ubuntu is available as a single image of more than 2.5 GB in size. The direct download works well for people with high-speed internet connection.

    However, if you have a slow or inconsistent internet connection, you’ll have a difficult time downloading such a big file. The download may be interrupted several times in the process or may take several hours.

  • Play a fun math game with Linux commands [Ed: Those who GNU programs, but Linux commands. But Jim Hall, the author of this piece, is participating in the campaign of hate against the FSF.]

    Like many people, I've been exploring lots of new TV shows during the pandemic. I recently discovered a British game show called Countdown, where contestants play two types of games: a words game, where they try to make the longest word out of a jumble of letters, and a numbers game, where they calculate a target number from a random selection of numbers. Because I enjoy mathematics, I've found myself drawn to the numbers game.

    The numbers game can be a fun addition to your next family game night, so I wanted to share my own variation of it. You start with a collection of random numbers, divided into "small" numbers from 1 to 10 and "large" numbers that are 15, 20, 25, and so on until 100. You pick any combination of six numbers from both large and small numbers.

  • 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.
