  • How to Leave Discord for Matrix Without Losing Friends

    Discord: the clear winner in easy text and voice chat in the gaming space. But Discord is not private (encrypted or self-hostable), and while they support open source projects, it is not itself open source. It works well and you can have your own (virtual) servers for just your friends, so what’s the problem?

    If you are like me, you might be concerned with who has access to your data and messages, as well as being reliant on a third party to not shut down your server, not sell your data, and support the product. And if you are trying (and succeeding!) to live on open source projects, that’s yet another reason to look into other options.

    Perhaps the best and most widely used protocol is the Matrix open standard (typically with Synapse, the reference server), paired with a popular client like Element (formerly Riot). As we all know though, herding cats is easier than getting a social group to change platforms. Matrix is an open protocol though and can be combined with APIs or client access to other protocols to bring them to Matrix.

  • How to Dual Boot Ubuntu and Windows on Two Disks (SSD & HDD)

    Dual booting Ubuntu and Windows is not that complicated and I have covered it in detailed tutorial in the past. Recently, I also wrote about dual booting on a Bitlocker encrypted Windows system.

    And yet here I am talking about it again. Why? Because the scenario is slightly different and several It’s FOSS readers have asked questions about this particular scenario.

    Here’s the scenario: you got a new computer. It comes with a SSD with limited disk space like 120 GB and an additional HDD with 500 GB or 1 TB disk space. This is usually the scene with gaming laptops where large disk space matters for storing game files but SSD is required for faster boot and computing experience. 1 TB SSD would increase the system price a lot and hence this particular combination of SSD and HDD.

  • How to change MTU size in Linux – Linux Hint

    MTU (Stands for Maximum Transmission Unit) is the maximum size of the packet that can be transmitted from a network interface. All the devices including servers and switches/routers involved in communication should have the same MTU size. Large MTU size has less overhead associated with it while the smaller MTU has less delay.

    The default MTU size in most of the Ethernet networks is 1500 bytes. However, you can change it as per the requirements. In this tutorial, we will explain how to change MTU size in Linux.

  • How to enable EPEL repository on AlamLinux 8 - Linux Shout

    Why do we need an EPEL repository on our Linux OS such as AlmaLinux, RHEL, and CentOS?

    RHEL, CentOS, and AlmaLinux official repository doesn’t offer all packages we need to install various common software. Thus, to fulfill this hollow space as compared to other Linux such as Ubuntu, the EPEL repository helps a lot. It offers additional packages for Enterprise Linux, which is administered by the Fedora Special Interest Group and they also ensure the high quality of the additional packages for Enterprise Linux.

    It is s maintained by a community of people who generally volunteer their time and no commercial support is provided.

    The good thing is the method to enable it is very simple and common for all RedHat-based Linux distros including AlmaLinux. However, those who are new to this OS can follow the steps given here.

  • 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.
