  • Navigate your FreeDOS system

    FreeDOS is an open source implementation of DOS. It's not a remix of Linux, and it is compatible with the operating system that introduced many people to personal computing. This makes it an important resource for running legacy applications, playing retro games, updating firmware on motherboards, and experiencing a little bit of living computer history. In this article, I'll look at some of the essential commands used to navigate a FreeDOS system.

    [...]

    FreeDOS can be very different from what you're used to if you're used to Windows or macOS, and it can be just different enough if you're used to Linux. A little practice goes a long way, though, so try some of these on your own. You can always get a help message with the /? switch. The best way to get comfortable with these commands is to practice using them.

  • How To Install KVM on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install KVM on Ubuntu 20.04 LTS. For those of you who didn’t know, KVM (Kernel-based Virtual Machine) is the virtualization solution for Linux. It consists of a loadable kernel module that allows the Linux Kernel to work as a Hypervisor. KVM provides hardware-assisted virtualization for a wide variety of guest operating systems.

    This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of the KVM virtualization on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

  • Ubuntu: increase swap [Guide]

    When installing Ubuntu, a swap file is created. The swap file is usually about 2 GB, though sometimes it can be larger. This swap file can do the trick for most Ubuntu users these days, as most modern PCs have a lot of performance and RAM.

    If you rely on swap a lot on Ubuntu because you’re regularly using up your physical RAM, the 2-4 GB swap file isn’t enough. Thankfully, it is possible to increase the swap’s size from the default to something much larger.

How I digitized my CD collection with open source tools

The restrictions on getting out and about during the pandemic occasionally remind me that time is slipping by—although some days, "slipping" doesn't quite feel like the right word. But it also reminds me there are more than a few tasks around the house that can be great for restoring the sense of accomplishment that so many of us have missed. One such task, in my home anyway, is converting our CD collection to FLAC and storing the files on our music server's hard drive. Considering we don't have a huge collection (at least, by some people's standards), I'm surprised we still have so many CDs awaiting conversion—even excluding all the ones that fail to impress and therefore don't merit the effort.

Hyperbola Linux Review: Systemd-Free Arch With Linux-libre Kernel

In the last month of 2019, the Hyperbola project took a major decision of ditching Linux in favor of OpenBSD. We also had a chat with Hyperbola co-founder Andre Silva, who detailed the reason for dropping Hyperbola OS and starting a new HyperbolaBSD. HyperbolaBSD is still under development and its alpha release will be ready by September 2021 for initial testing. The current Hyperbola GNU/Linux-libre v0.3.1 Milky Way will be supported until the legacy Linux-libre kernel reaches the end of life in 2022. I thought of giving it a try before it goes away and switches to BSD completely. Read more
