  • How to Add and Configure Swap Space on Ubuntu Linux

    SWAP is a partition or a disk space that can take some load for RAM and can be used as a memory space on Ubuntu systems. Normally, while installing a new Linux-based operating system, it will offer you to create a new SWAP partition. The file partition has a SWAP flag, and usually, the size of a SWAP space is 2GB on average. When the system memory is full, the Linux kernel automatically moves some unused files into the SWAP area instead of stopping them. As we know, in Linux, everything is either a file, SWAP can handle files pretty well. So, if you’re using a Ubuntu system on a virtual machine, you definitely should try adding SWAP space to your machine.

  • How to Disable/Enable Automatic Screen Lock in Linux Mint 20 trough CLI

    Automatic screen lock is a feature provided by all widely used desktop operating systems. There is a default period of inactivity set in your system settings, after which your screen is automatically locked and you have to reactivate it by either clicking somewhere or entering your login password. This feature is best for scenarios when you need to stay away from your computer for some time and you have some critical data stored on your system. In the meantime, while you were away from your system, any intruder can break into the system and steal your critical data. For this reason, an automatic screen lock is very helpful to ensure the security of your data.

    Automatic screen lock is enabled by default on most operating systems. On the other hand, if you are physically present near your computer and simply doing other tasks at the same time, then this automatic screen lock feature may prove to be annoying as you have to enter your password again and again after a few minutes of inactivity. In this situation, you can consider disabling your system’s screen lock feature for some time and then re-enabling it once you are done with your work. Today we will show you how to disable/enable the automatic screen lock via the Linux Mint 20 CLI.

  • Mount cue/bin image files with CDemu - Fedora Magazine

    The other day I needed to burn a disc. Yeah, I know, some of you might be wondering, “A disc? What’s that?” Others might ask, “Are you really using that archaic media?”

    Well, yes I am. I feel there is still something charming about physical things that digital media cannot replace.

    I needed to burn a very old game that was comprised of a cue file, some audio tracks in cda format, and a bin file which stored all the binary content that was indexed by the cue file.

    First I tried to use Brasero. Yeah I know, it’s old but it does the job generally and it fits with the rest of the system, so it’s my choice generally. Unfortunately, this time it was not up to the task. It stated that it had some problems reading the cue file. Then I tried Xfburn and K3b. But neither of those worked either. They both detected the bin file but not the cda files.

  • 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.
