  • 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.

  • MiTubo 1.0: playlist support, new “website” | Mardy

    Expanding a bit on the points above, the first thing worth saying is that the choice of releasing this version as “1.0” does not mean that it's more stable than the previous ones; it just means that I'm rather satisfied with the feature set, and that I believe that the program is ready for more widespread use. This is also the reason why I decided to prepare a web page for it: mardy.it/mitubo. I didn't go for a completely separate website, unlike what I previously did for Mappero Geotagger, PhotoTeleport and Imaginario (which reminds me that I haven't been working on the latter for a long time! I should try to correct this soon!), both because this way it's simpler to publish news about it (I'll continue doing that here, instead of cross-posting in two sites), and because having it in the same domain might be mutually beneficial for the SEO ranking of the blog and of MiTubo.

  • Adriaan de Groot: Blue Systems Farewell

    Calamares serves the needs of several dozen Linux distributions, large and small. I’ve been running the Calamares project for five years now, sponsored by Blue Systems who have supported the Calamares project since its beginning and through two maintainers now. After these five years, I have decided to hand in my badge and move on to different things. This means that I’m no longer paid to spend three days a week on Calamares and my involvement is going to be dialed back to incidental-volunteer-contributor. This means that maybe I’ll finally ignore Linux distro’s and sit down to make it work for FreeBSD.

  • Strengthening digital infrastructure: A policy agenda for free and open source software

    While there is little debate that digital forces are playing an increasingly crucial role in the economy, there is limited understanding of the importance of the digital infrastructure that underlies this role. Much of the discussion around digital infrastructure has focused on broadband availability (which is certainly important), but the role of free and open source software (FOSS or OSS) has gone underappreciated. FOSS—software whose source code is public, is often created by decentralized volunteers, and can be freely used and modified by anyone—has come to play a vital role in the modern economy. It is baked into technology we use every day (cars, phones, websites, etc.), as well as into various aspects of critical infrastructure including our finance and energy systems.

  • Improve legibility and reduce layout shifts with x-height adjustments

    There’s more to setting the text size on your webpages than just the CSS font-size property. It only controls the size of majuscule (“uppercase”, e.g. “A”) letters, numbers, and punctuation. The size of minuscule (“lowercase”, e.g. “a”) letters is left up to the font. [...] Unfortunately, font-size-adjust is only supported in Firefox. It has been supported by this browser for over a decade already. It was implemented in Chrome for almost half a decade, but it has been left to rot behind the Experimental Web Platform features flag. It’s not implemented in Safari.
