  • How to install and use Firewalld on Almalinux 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 AlmaLinux 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.

Terraform untaint allows you to remove that tainted condition from the resource. So, why is that useful? What are the use cases for terraform taint?

6 Reasons to Pick Linux Over Windows

Almost all students do their work on laptops and PCs that run on Windows. Of course, some of you are lucky enough to afford something that runs on Apple’s macOS. While Windows is a popular OS, it’s far from being perfect. Few students are even aware that their PCs and laptops can run on various operating systems.

One of the alternatives students often overlook is Linux. Many believe that this OS is hard to manage. That’s why they prefer to either buy or, in some cases, pirate Microsoft’s creation unless it comes pre-installed on the device, of course.

It’s true that Linux is harder to install than its counterpart. But it has a lot more to offer than meets the eye. So, what exactly sets it apart?

    It's Brian Kernighan discussing the formation of Unix, starting from the back story of the creation of Bell Labs, including predecessors CTSS and Multics, and C predecessors BCPL which was modified to become B, and why Dennis Richie added types to B to make C.

    This video really hits its stride when Kernighan discusses piping and redirection, and the ease of creating wonderful things out of small parts that, and Kernighan used these words, "do one thing and do it well."
