The steam app is free to download, and along with paid games, it offers hundreds of free-to-play games as well. Many games now natively support Linux; in this guide, we will provide an installation process as well as the instructions to set up steam on Manjaro Linux.

  4. How to fully disable the Firewall on Linux Mint

    A firewall is a network security system built into an operating system that monitors and manages network traffic according to preset rules. The firewall also aids in the monitoring of networks to determine whether they are trustworthy or not. They also protect your PC from hackers by filtering dangerous network traffic.

    The uncomplicated firewall (UFW) in Linux Mint provides a user-friendly interface for managing firewall rules. Its main goal is to make firewall rule management as simple as possible, as the name suggests. Although it is recommended that you keep the firewall turned on, there may be times when you need to disable it, such as when troubleshooting or testing. So this article will provide you the details on how you can disable a firewall on Linux Mint.

  5. How to extract rar files on Manjaro

    RAR is a file format used to combine multiple files/folders in a single compressed file. The .rar file extension refers to the RAR files, and several applications can create these files. The RAR file format is practiced compressing files used for various purposes like you can keep various types of files inside one compressed file. These compressed files are then extracted to access the files contained by them.

    The rar files can be extracted by using the graphical interface and terminal support of Manjaro. In Linux-based systems, unrar command-line utility is required to extract .rar files.

    In this piece of writing, we have provided possible ways to extract rar file in Manjaro Linux. As the interaction with rar files is impossible without the unrar package. So, we will also provide the installation procedure of the unrar package as well.

  6. How to enable remote access in Manjaro Linux

    Enabling remote access is crucial when you need to permit your office members to work from the branch office, home or when you want to hand over your system to the IT teams for troubleshooting purposes. However, when you want to access your own Linux-based system from anywhere, any time, without the hassle then the ideal way is to utilize remote desktop software or SSH.

    This post is all about how to enable remote access on Manjaro Linux. For this purpose, we will first use SSH and then show you the procedure of installing and configuring Chrome Remote Desktop to establish a remote connection between your Manjaro system and mac. This post will also discuss some other remote desktop software for a Linux system. So, let’s start!

  7. How to enable SSH on Linux Mint

    Enabling SSH on Ubuntu is one of the first things you should do after installing the operating system as it provides an encrypted network protocol for safeguarding remote server and client logins. It allows you to access your machine remotely and execute operations securely. It encrypts all client-server traffic to prevent eavesdropping, connection hijacking, and other types of attacks.

    Secure Shell (SSH) protocol is used to manage or transmit data between computers through the internet. Old methods for accomplishing these actions, such as telnet do not have these capabilities. They are unsafe since they transmit the user’s password in plaintext. It offers a secure route over an unprotected network, connecting an SSH client program to an SSH server in a client-server architecture. It is mainly used to communicate to Unix-like operating systems, although it may also be used on Windows.

  8. How to add a user on Linux Mint

    Linux is reliable and secure compared to other operating systems, yet granting complete permissions to an unskilled user might lead to severe difficulties. This is where the administrator took control, one of the most important aspects of being a system administrator is user management. Because there are so many critical components to administrate, even the tiniest error can result in the intruders taking over the entire system. The system administrator can create, add and give each user a separate set of permissions. When a user is added or created, the appropriate level of access is granted to that user. Adding a user on Linux Mint can be accomplished in two ways; through the terminal and through GUI.

  11. What is a Tar File

    Tar is a powerful archiver that is frequently used for collecting files and archiving them. It was created to produce archives for data storage on tapes, thus the name “Tape Archive”. It was initially included in UNIX version 7 in 1979, and it is currently accessible on a variety of systems.

    Before we go into the situation’s specifics, let’s define Archive files so that no Linux newbies are left out. Archived file is a combination of multiple files with metadata information. By combining multiple files and their information into a single file, you may improve the storage and mobility of your data. The basic purpose of Tar is to combine the data but you can also compress the data using other utilities. These compressed files are referred to as Archive files, and they assist users to reduce file size and simplify data management. The tar is one of the must-have utilities for managing various files in Linux.

Ubuntu 21.04 (Hirsute Hippo) Reached End of Life, Upgrade to Ubuntu 21.10 Now

Dubbed by Canonical as the “Hirsute Hippo,” Ubuntu 21.04 was released nine months ago, on April 22nd, 2021. It was the first Ubuntu release to use the next-generation Wayland display server by default for its Ubuntu Desktop flavor, which uses a modified version of the GNOME desktop environment. Ubuntu 21.04 didn’t make the plunge into the GNOME 40 desktop environment series due to its redesigned Activities Overview, but it did ship with support for GNOME 40 apps while being built on top of the older GNOME 3.38 desktop environment series.

  • Supplino is a variable benchtop power supply that you can build yourself | Arduino Blog

    Working with electronics requires access to stable power in a variety of voltages. Some components require 3.3V and others require 5V. Still others need 9V or 12V — there are many possibilities. You could keep a variety of wall warts on hand, but a variable benchtop power supply is a more convenient option. Supplino is one choice and this guide from Giovanni Bernardo and Paolo Loberto will walk you through how to build one. Supplino can accept anything from 4 to 40 volts and can output anything from 1.25 to 36 volts, with a maximum of 5A. An XH-M401 module with an XL4016E1 DC-DC buck converter handles the voltage regulation. Technically, you could use that alone to power your components. But the addition of an Arduino Nano board (or Nano Every) makes the experience far friendlier. It monitors the power supply output and drives a 1.8″ 128×160 TFT LCD screen, which displays the present voltage, amperage, and wattage.

  • Relocating Fedora's RPM database [LWN.net]

    The deadlines for various kinds of Fedora 36 change proposals have mostly passed at this point, which led to something of a flurry of postings to the distribution's devel mailing list over the last month. One of those, for a seemingly fairly innocuous relocation of the RPM database from /var to /usr, came in right at the buzzer for system-wide changes on December 29. There were, of course, other things going on around that time, holidays, vacations, and so forth, so the discussion was relatively muted until recently. Proponents have a number of reasons why they would like to see the move, but there is resistance, as well, that is due, at least in part, to the longstanding "tradition" of the location for the database.

Server: MongoDB vs. DynamoDB, Mirantis, and More

  • MongoDB vs. DynamoDB: What you need to know

    NoSQL databases have become more popular because of the need for more flexible backend solutions. These databases run applications that require a more flexible data structure than traditional structured databases can provide. Robust feature-rich NoSQL database platforms famous for NoSQL databases include MongoDB and DynamoDB. This article guide will compare these two databases to help you choose the right one for your project.

  • Mirantis brings secure registries to Kubernetes distros | ZDNet

    Mirantis Secure Registry, formerly Docker Trusted Registry, provides an enterprise-grade container registry solution. You can use this as a foundation to build a secure software supply chain. It does this by providing you with access to a container image registry that has enhanced levels of security beyond that of public registries. This, in turn, gives you more control over this critical part of their software supply chain. The comprehensive, built-in security enables users to verify and trust the automated operations and integration with Continuous Integration/Continuous Delivery (CI/CD) pipelines to speed up application testing and delivery. You can use MSR alongside your other apps in any standard Kubernetes 1.20 and above distribution, via standard Helm techniques. While the new MSR is no longer integrated with Mirantis Kubernetes Engine (MKE) as it was earlier, it still runs as well as ever on MKE as it does with any other supported Kubernetes distribution.

  • The Success of ‘Open-hearted’ Partnerships in the Cloud | SUSE Communities

    The future is open — and it’s better together. At SUSE, we pride ourselves on our partnerships, and sometimes what we can achieve together surpasses even our greatest hopes. That’s what our award-winning, cloud-based, high-performance computing (HPC) partnership with UberCloud, Dassault Systèmes, and Google Cloud achieved, by enabling 3DT Holdings researchers to create an affordable, real-time heart surgery simulator for physicians to use when it matters most. This is an ongoing relationship with the Living Heart Project that we think is just the beginning of what this ground-breaking research can achieve — and the lives it can save.

Programming Leftovers

  • An outdated Python for openSUSE Leap [LWN.net]

    Enterprise distributions are famous for maintaining the same versions of software throughout their, normally five-year-plus, support windows. But many of the projects those distributions are based on have far shorter support periods; part of what the enterprise distributions sell is patching over those mismatches. But openSUSE Leap is not exactly an enterprise distribution, so some users are chafing under the restrictions that come from Leap being based on SUSE Enterprise Linux (SLE). In particular, shipping Python 3.6, which reached its end of life at the end of 2021, is seen as problematic for the upcoming Leap 15.4 release. [...] OpenSUSE and SLE have generally been aligned over the years. In 2020, Leap and SLE grew even closer together. The build system and repositories between the two were shared starting with Leap 15.2, which corresponded to the second "service pack" (SP) of SLE (i.e. SLE 15-SP2). In 2021, with Leap 15.3 and SLE 15-SP3, the two distributions effectively merged, such that all of the base packages were shared between the two. To a first approximation, Leap is an openSUSE-branded version of SLE, much like what CentOS used to be for Red Hat Enterprise Linux.

  • Make Your Python CLI Tools Pop With Rich | Hackaday

    It seems as though more and more of the simple command-line tools and small scripts that used to be bash or small c programs are slowly turning into python programs. Of course, we will just have to wait and see if this ultimately turns out to be a good idea. But in the meantime, next time you’re revamping or writing a new tool, why not spice it up with Rich?
