  2. Pin App Shortcuts to Ubuntu Desktop as easy as in Windows 10 via Extension | UbuntuHandbook

    Adding an app shortcut icon to the Desktop in Ubuntu is not that easy for beginners by default. User has to first open the folder that stores the app shortcut files (usually /usr/share/applications). Then drag and drop the .desktop files into user’s “Desktop” folder. Make executable in file properties dialog and finally select ‘Allow Launching‘ via context menu option.

    To make life easier, a Gnome extension is available to make the process to create a desktop shortcut for apps as easy as few clicks. Since Ubuntu uses full-screen app launcher, it’s not Windows 10/11 style drag and drop adding desktop icons. Instead, it adds ‘Add to Desktop‘ option to app icon’s context menu.

    Like in Linux Mint and/or Zorin OS, user just needs to search the app in ‘Show Applications’ or ‘Activities’ overview screen, right-click on the app icon, and finally click ‘Add to Desktop’ to pin to desktop.

    Ah, the age-old question. You got a Chromebook but you are also an Apple user and you want to access your iTunes library on your shiny, new Chrome OS devices. Unfortunately, Apple has yet to – and likely never will – release an Android version of iTunes. Many users have made the move to Apple Music and are content using the Play Store version or simply navigating to Apple Music on the web. However, there are many that have an extensive iTunes library and still others use the storefront on a regular basis for purchases and media consumption. Wouldn’t it be nice if you could do so on your Chromebook?

  • How to install and use Firewalld on Rocky Linux 8 - Linux Shout

    Firewalls are one of the most essential parts of security when we are going online. Here we learn the steps and command to install, configure, and how to use FirewallD on Rocky Linux 8 using CLI or GUI. Many of us who are not already Linux would already be familiar with the firewall feature on Windows, where it is very easy to turn On or Off ports or services using GUI. However, what about Linux such as CentOS, Rocky Linux, RedHat, AlmaLinux, and more… If you are using full Linux Desktop then a firewall would already be there but in most of the cases without a graphical interface. Nevertheless, Debian, RedHat, Ubuntu, and other Linux systems provide the appropriate firewall GUI software directly from their respective repository to manage things with the help of mouse clicks. But what if you just want a basic OS installation with no graphical interface? Because minimal versions of Linux would not even have the CLI version of Firewall by default. Well, this is a very small problem, if you have an active internet connection and due to an in-built package manager under Linux, we can install a firewall with just a single command.

Building a Retro Linux Gaming Computer - Part 9: Ancient Archaeology

After the demise of Loki Software, one of their former employees found himself forced to work behind a cash register for a living. Desperate to get back to porting games, he found the email address of an artist working for the Croatian developer Croteam, creators of the game Serious Sam. Croteam agreed to let him attempt to create a port of the game to Linux, the first of many games to come to the platform thanks to the work of Ryan “icculus” Gordon. The port of Serious Sam though would in the end never leave the beta stage. Croteam later released the source code to the game in 2016, with Ryan himself returning to craft his own source port, but his original effort languished for years with a number of unfortunate bugs. One of these left the game unbeatable as it prevented the player from inflicting any damage to the final boss. Unbeatable that is with the standard version of the game. Our friends at Global Star Software released Serious Sam: Limited Edition in 2002, a bizarre budget retail variant of Serious Sam: The First Encounter that only features seven out of the fifteen levels. It also happens to be the only version of the game that I possess on CD-ROM. I initially dismissed the idea of playing Serious Sam as I thought it would be too much for the hardware, but the jewel case insists that the Rage 128 Pro is compatible. Read more
