• Vector VS. Raster Images: Choosing The Right Format

  A vector graphic's small file size and scalability makes it uniquely suitable for use in digital printing from business cards to billboards. They're also used in lower thirds for videos, web-based objects and rendering 2D or 3D computer animation. Their native files are needed for coin designs, laser engraving, t-shirts, patches, etc. Raster images are best for digital photos and print materials. If your project requires scalable shapes and solid colors, vector is the best choice, but if your project requires complex color blends, raster is the preferred format.

• How to Migrate to Fedora Linux from Ubuntu [Beginner’s Guide]

  Here’s a quick model on how to migrate to Fedora from the Ubuntu desktop, for good & save yourself from “snap drama”.

  Ubuntu and Fedora – are both great Linux operating systems.

  They are used by millions of users every day and are available for desktops, servers, and cloud deployments. Fedora is sponsored by Red Hat and developed by the community, whereas Ubuntu development is managed by Canonical.

  They follow a separate release schedule and have a different package management process. Otherwise, they are the same if you think of them as just a Linux distribution. So that said, it is not that difficult to migrate to Fedora for a long-term Ubuntu user. And use Fedora as a daily driver.

• How to Monitor and Optimize Power Usage on Linux?

  Battery use on Linux is particularly high as compared to other operating systems. One of the reasons behind this unusual power drainage is that the hardware vendors do not provide the essential documentation for Linux kernel developers to create the power optimized drivers. Linux holds just 2% of the market share in desktop technology which is why an adequate attention is not given in this area. As Linux users, we ought to be concerned about monitoring the power use on our systems and be aware of the different ways where we can optimize the battery/power usage.

  Today, we will explore how to monitor the power usage on Linux using different ways. We will first see how it can be achieved via Graphical User Interface (GUI). Then, we’ll make use of the Linux command line to achieve the same. We will also discuss some methods to optimize the power usage on a Linux system. In this tutorial, we demonstrate the steps on an Ubuntu 22.04 system. The commands that are used in this guide are simple. And the tools that we use can be easily installed in Ubuntu 22.04. Most of the methods discussed here can be replicated on almost all Linux distributions.

• How to install Virt-Manager on Ubuntu 22.04 LTS Linux

  Virtual Machine Manager, also known as virt-manager or VMM for short, provides a unified user interface for creating and managing virtual machines. VMM relies on libvirt, i.e. it supports the virtualization solutions that libvirt also supports. These include QEMU, KVM, and Xen, but not VirtualBox or VMware Player.

  VMM offers both a graphical user interface and several command-line programs. VMM is written entirely in Python.

  The special feature of VMM is that it forms a kind of intermediate layer so that the management of the virtual machines is uniform, no matter which virtualization solution is used, which reduces the administration effort. The configuration is stored in XML files so that this can also be corrected manually as required. The managed virtual machines can also be located on another computer (e.g. another server), and the connection to it can also be encrypted.
