  • 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.

  • The Old Computer Challenge V2: back to RTC

    This new challenge will embrace the old time of RTC modems with a monthly time budget. Back in these days, in France at least, people had to subscribe to an ISP for a given price, but you would be able to connect only for 10, 20, 30, 40... hours a month depending on your subscription. Any extra hour was very expensive. We used the Internet the most efficiently possible because it was time limited (and very slow, 4 kB/s at best). Little story, phone lines were not available while a modem was connected, and we had to be careful not to forget to manually disconnect the modem after use, otherwise it would stay connected and wasting the precious Internet time! (and making expensive bills)

An experiment to test GitHub Copilot's legality

GitHub is enabling copyleft violation ✨at scale✨ with Copilot. GitHub Copilot encourages people to make derivative works of source code without complying with the original code’s license. This facilitates the creation of permissively-licensed or proprietary derivatives of copyleft code.

Unfortunately, challenging Microsoft (GitHub’s parent company) in court is a bad idea: their legal budget probably ensures their victory, and they likely already have a comprehensive defense planned. How can we determine Copilot’s legality on a level playing field? We can create legal precedent that they haven’t had a chance to study yet!

A chat with Matt Campbell about a speech synthesizer gave me a horrible idea. I think I know a way to find out if GitHub Copilot is legal: we could use its legal justification against another software project with a smaller legal budget. Specifically, against a speech synthesizer. The outcome of our actions could set a legal precedent to determine the legality of Copilot.
