• How to Install NVIDIA Drivers on Fedora 37 Linux

  When it comes to graphics processing, speed is often of the essence. For any Linux user who relies on their system for gaming or graphic design, having the fastest drivers possible is essential. While most modern Linux distributions come with Nouveau drivers pre-installed, these are often not the most up-to-date or well-supported drivers available. However, the Nouveau open-source graphics device driver for Nvidia video cards is typically slower than Nvidia’s proprietary or open-source driver and lacks support for the latest hardware features and software technology. In most cases, upgrading to proper NVIDIA drivers will provide a much better experience. In some situations, the improvement in speed and performance can be substantial.

  The following tutorial will teach you how to install the Nvidia Drivers on Fedora 37 Linux from the Nvidia Proprietary Repository RPM Fusion or Nvidia RPM Cuda REPO using cli with the command line terminal.

• 24 of our favorite articles in a downloadable eBook

  One day in March of 2020, a few of my Opensource.com teammates and I grabbed lunch to talk about how we would work from home for the next couple of weeks until this pandemic got nipped in the bud. At the end of the work day, I packed up my laptop and walked out the door of our office building. Several months later, we were all still working from home. None of us had returned to our office-based workstations. In July 2020, using safety precautions, we were granted access to our workstation solely to retrieve personal items. My desk was left exactly as I left it that afternoon in March. Expiring snacks stashed in my secret drawer. Picture frames collecting dust. Comic strips pinned up.

  And a pile of several bound copies of Best of a decade on Opensource.com 2010-2019. Our last yearbook that was published (and printed)!

  Like most folks, the Opensource.com community had to pivot how we operated in order to stay connected. Sure, we continued our weekly video calls. But in-person conferences, a unique time where people would travel from all over the world to be together, were out of the question. Though some of this operational stuff has changed, the connection with one another has strengthened. It is due time to publish a new yearbook to honor that connection. This yearbook was created to celebrate our correspondents.

  The�Opensource.com Correspondent Program�recognizes the critical group of our most trusted and committed contributors. We recently closed out yet another successful program year with 24 correspondents. Each correspondent selected their favorite article to be included in this downloadable yearbook. In it,�you'll find Raspberry Pi tutorials, career stories, home automation tips, Linux tricks, and much more.

• How I switched from Docker Desktop to Colima

  DDEV is an open source tool that makes it simple to get local PHP development environments up and running within minutes. It’s powerful and flexible as a result of its per-project environment configurations, which can be extended, version controlled, and shared. In short, DDEV aims to allow development teams to use containers in their workflow without the complexities of bespoke configuration.

  DDEV replaces more traditional AMP stack solutions (WAMP, MAMP, XAMPP, and so on) with a flexible, modern, container-based solution. Because it uses containers, DDEV allows each project to use any set of applications, versions of web servers, database servers, search index servers, and other types of software.

  In March 2022, the DDEV team announced support for Colima, an open source Docker Desktop replacement for macOS and Linux. Colima is open source, and by all reports it’s got performance gains over its alternative, so using Colima seems like a no-brainer.

  There is a technical transition taking place in the desktop Linux world.

• How to Install Custom Fonts on Linux (Ubuntu, Debian, RedHat) - TREND OCEANS

  Linux gives you complete freedom to experiment with the user experience. For this reason, one can try to change the desktop environment to any window manager like i3wm, bspwm, xmonad, etc. Not only that, but you can also change your display manager and audio manager from what you have received from the installed distribution.

  But we are not here to change any of these things except the font, because after the installation you may not be able to view some of the fonts in Devnangari like Sanskrit, Hindi, Marathi, and Dravidian languages like Telugu, Tamil, Kannada, and Malayalam.

  Because of that, you might face problems reading content in your regional languages.
