  • The 10 Important Linux Jargon Busters | FOSS Linux

    What better way to filter through the Linux World than through a Linux jargon buster? The Linux system has, for some time, been the UFO of the Operating Systems universe. Not long ago, the public pronunciation of the word Linux would have mirrored concerning glares from OS users who were yet to understand it. However, as with all the UFO protocols, the most daring step is making the first contact.

    The first contact between the curious OS users and the Linux system turned out to be a blessing in disguise or, as the cool kids say, a match made in heaven. It was a perfect friendship. However, for a friendship to last, there must be a means of communication. The SI unit of communication is language. The language of communication between Linux and most of its curious supporters was not blissful initially and turned out to be jargon. However, it never implied that Linux is unteachable.

    To navigate the Linux world comfortably, you only need to master and understand a few key terms. Afterward, you will be ready to certify yourself out of the Linux beginner’s class. This article has the Linux jargon busters as the main guests. Let us give this Linux jargon the stage to introduce themselves before the jargon busters take center stage. We should understand this sort-after Linux jargon in a way that relates to their contribution to the Linux OS.

  • How To Install Bitcoin Core Wallet on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install the Bitcoin Core Wallet on Ubuntu 20.04 LTS. For those of you who didn’t know, Bitcoin Core is programmed to decide which block chain contains valid transactions. The users of Bitcoin Core only accept transactions for that blockchain, making it the Bitcoin block chain that everyone else wants to use. It is these users who keep Bitcoin decentralized. They individually run their own Bitcoin Core full nodes, and each of those full nodes separately follows the exact same rules to decide which blockchain is valid.

    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 Bitcoin Core Wallet 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 compare video files on Linux with Identity

    Identity is an exciting program for Linux that allows Linux users to take two video clips and compare and contrast them. If you’re a video editor that uses Linux, this could be a useful program. Here’s how to use it.

    [...]

    Identity is a handy tool, but it does not come pre-installed on any Linux operating systems (that we know of). For this reason, we must demonstrate how to set up the Identity app on Linux before continuing with this guide.

    There are three ways to get the Identity app set up on your computer. The first (and arguably best) way is Flatpak. However, if you do not like the Flatpak app store, you can install it through the Arch Linux AUR or even the source code.

    To start the installation of Identity on your Linux PC, launch a terminal window on the desktop. Once the terminal window is open and ready to use, follow along with the installation instructions outlined below that corresponds with the instructions, you prefer.

  • How to Enable KVM Virtualization on Raspberry Pi 4 – Linux Hint

    The full form of KVM is Kernel Virtual Machine. It is the virtualization solution for Linux. KVM is a Linux kernel module that allows the Linux kernel to act as a hypervisor program like VMware ESXi or VSphere.

    Up until now, you could not run KVM virtualization on Raspberry Pi devices. One of the main reasons for this was that the Raspberry Pi 3 and older versions have only 1 GB of memory. 1 GB of memory is insufficient for KVM virtualization. Docker is a better solution for these devices.

    The recently released Raspberry Pi 4 8 GB model made KVM virtualization possible on the Raspberry Pi. Linux distributions like Fedora, Manjaro, etc., made KVM virtualization easy for the Raspberry Pi 4 by precompiling the KVM Linux kernel module. Our all favorite Raspberry Pi OS may follow this path someday as well.

    In this article, I am going to show you how to install KVM on Raspberry Pi 4 and create a KVM virtual machine on the Raspberry Pi 4. So, let’s get started.

  • FREE 4 Hour Ubuntu Course for Beginners [Ed: This course must not be too good/factual if they skip GNU and leap to 1991]

    Linux is a well-known operating system. In 1991, Linux was created by a university student named Linux Torvalds. All software’s architecture is covered with Linux, as it helps to communicate between the computer program and the system hardware and also manages the requests between them. Linux is open-source software. It is distinguishable from other operating systems in many ways. People having professional skills related to programming can also edit their code, as it is freely available for everyone. Torvalds intended to name his creation as ‘freaks,’ but the administrator used to distribute the code by its creator’s first name and Unix, so that name stuck.

  • Monitoring failed login attempts on Linux [Ed: Those are GNU programs (grep, head…), not “LINUX”]

  • How to Secure the SSH Server in Ubuntu 20.04 from Basic to Advanced – Linux Hint

    Just like all other servers, the SSH server is also prone to unauthorized access attempts. Therefore, whenever you wish to use an SSH server, you must have considered securing it first to save yourselves from any unwanted situation in the longer run. Generally, the term “securing a server” is also known as “hardening a server.” This can be done by taking multiple measures. These measures depend upon the level of security that you require.
    The measures of securing the SSH server range from basic to advanced, and as we said earlier, you can pick them up according to the level of security that you need. You can skip any of the prescribed measures if you have sufficient knowledge about the consequences and if you are in a good position to face them. Also, we can never say that a single step will ensure 100% security, or a certain step is better than the other.

    It all depends upon which type of security we actually need. Therefore, today we intend to give you a very deep insight into the basic and advanced steps for securing an SSH server in Ubuntu 20.04. Apart from these methods, we will also be sharing with you some additional tips for securing your SSH server as a bonus. So let us get started with today’s interesting discussion.

  • Automate your tasks with this Ansible cheat sheet | Opensource.com

    Ansible is one of the primary tools in the world of automation and orchestration because of its broad usefulness and flexibility. However, those same traits are the very reason it can be difficult to get started with Ansible. It isn't a graphical application, and yet it also isn't a scripting or programming language. But like a programming language, the answer to the common question of "what can I do with it?" is "everything," which makes it difficult to know where to begin doing anything.

    Here's how I view Ansible: It's an "engine" that uses other people's modules to accomplish complex tasks you describe in a special "pseudo-code" text format called YAML.

    One of the main features of appimage-builder is building an AppImage from existing, pre-compiled traditional packages like Debian packages, RPM packages, etc. Currently, only Debian packages are supported; however, more package managers will be supported in the future, such as Pacman.

    Over the last year or so as part of my role at Red Hat I started working with some of the NVidia Tegra team to improve support for the Jetson devices. This work has been wide ranging and while it’s taken a little while, with Fedora 33 we’re starting to see the fruits of that collaboration. The first is improved support for the Jetson Nano. The official L4T (Linux 4 Tegra) Jetson Nano images look is a lot like an Android phone with numerous partitions across the mSD card. This makes it harder to support a generic Linux distribution like Fedora as there’s assumptions by distributions of what level of control they can have over a storage disk, so while it was certainly possible to get Fedora to run on these devices it generally wasn’t for the faint of heart
