  • Modern public TLS is a quite different thing than it used to be

    If you're not deeply involved with TLS, it probably seems that the state of public TLS today is much the way it used to be a decade ago, or even five years ago, including things like the fundamental problem with TLS on the web (which is that your browser trusts a ton of Certificate Authorities). This is not actually the case, for at least three reasons. Two of them are logistical changes, while the third is a dramatic change to the security of TLS in practice.

  • How to Create Sudo User on RHEL | Rocky Linux | AlmaLinux

    Sudo user is the regular user in Linux which has admin or root privileges to perform administrative tasks. But, by default all regular users in Linux are not sudo users, root user has to manually assign sudo rights to the user by adding it to wheel group.

    In RHEL distributions like Red Hat Enterprise Linux, Rocky Linux and AlmaLinux, a group with name ‘wheel’ is created during the installation and its entry is already defined in system’s sudoers file.

  • How to Install and Configure NFS on Ubuntu 22.04/20.04

    The concept of NFS (Network File System) empowers a user on a client computer to have read and write privileges on shared file directories on a server computer.

    This over-the-network file-sharing concept is implementable by anyone due to its open-source attribute. Before this article guide teaches us how to implement the NFS protocol, we first need to understand some of the NFS footprints.

    Since it is the server computer that hosts the shareable files, it is also the one that decides the implementable depth of file-sharing permissions and access rights.

    This article guide assumes that you have access to an Ubuntu 20.04/22.04 server and a client computer. It also assumes that you have root or Sudo user access on both operating system environments.

  • Install GNOME Tweaks on Debian 11 Bullseye - LinuxCapable

    GNOME is a popular desktop used on many Linux distributions, including Debian. The GNOME Tweaks tool allows users to modify and change the cosmetics in their GNOME desktop environment, which is popular amongst users that are not satisfied entirely with the GUI.

    Some of the things you can do with GNOME Tweaks are edit font colors and scaling, disable animations for desktop speed improvement, change themes, manage GNOME extensions, bar changes, and much more.

    Depending on the installation you choose when installing Debian 11, this may already be installed on your desktop.

    In the following tutorial, you will learn how to install GNOME Tweaks on Debian 11 Bullseye.

  • Getting started with Tkinter for Python tutorial

    Tkinter stands for “Tk interface”: the package with the same name on many Linux distributions provides the Python bindings for the Tcl/Tk GUI toolkit. Although other graphical toolkit can be used from Python, like Qt or GTK, Tkinter is the standard (the Python IDLE editor and development environment is written using this toolkit, for example) and probably the easiest to work with. In this tutorial we see the basic concepts behind the usage of Tkinter and how to create and interact with some of the most used widgets.

  • 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.
