Poettering is best known for systemd. After a lengthy stint at Red Hat, he joined Microsoft in 2022. Kühl was a Microsoft employee until last year, and Brauner, who also joined Microsoft in 2022, left this month. The trio are leading lights in the Linux and open source world. Brauner posted on Mastodon: "My role in upstream maintenance for the Linux kernel will continue as it always has." Poettering will similarly remain deeply involved in the systemd ecosystem.
I recently wrote about my migration away from VirtualBox to KVM/Virt-Machine for my virtual machine needs. I've found those tools to be far superior (albeit with a bit more of a learning curve) than VirtualBox. Since then, however, I've found another method of working with KVM (the Linux kernel virtual machine technology), one that not only allows me to create and manage virtual machines on my local computer, but also from any machine on my LAN. That tool is Cockpit, which makes managing your Linux machines considerably easier.
Linux has a tool for everything. Sometimes those tools come in the form of an easy-to-use GUI, and other times a command is necessary. For monitoring network traffic, your best bet is the command line. Once you dive down the rabbit hole of possible commands for this task, you could become overwhelmed with choices -- and with the complexity of some of those commands.
Hold on. There's yet another method, one that comes from MacOS. That method is Homebrew. What is Homebrew? Homebrew is a free, open-source package manager for Linux and MacOS that simplifies the installation and management of software. Think of Homebrew as a command-line version of the App Store that allows you to install command-line tools such as Python, Node.js, and more with ease.
The native Linux app is a highly requested feature for GeForce Now, especially as subscribers have had to rely on unofficial apps or browser tweaks to get access to the service. A beta of GeForce Now for Linux will be available initially for Ubuntu 24.04 and newer soon, nearly a year after Nvidia made it easier to access GeForce Now on the Linux-based SteamOS.
There are now several Linux distributions that offer outstanding gaming experiences. These distros not only include the software required to play games from services like Steam, but also vastly simplify the setup process, so you start playing your favorite games after just a few clicks. With a user-friendly installer, you won't even have to touch the command line.
In 2022, Debian developers decided to include some much-needed but non-free firmware to enhance their distribution's compatibility with a wider range of hardware. There were several reasons for this, including the state of open-source firmware for Nvidia GPUs. Given the importance of graphics devices in relation to AI, having firmware and drivers that are fully capable can mean the difference between them working properly and not.
The nmap command (short for network mapper) is a network exploration/security auditing tool that can rapidly scan networks to help you find out what hosts are available. With nmap, you can discover open ports and services, and even find out what operating systems are on your network. I've used nmap to find out what machines are on a network and what ports/services are open. If I find a port that shouldn't be open, I can close it to avoid security issues.
I started using Linux prior to the advent of sudo. Back then, any time I needed to run admin tasks, I had to first su to the root user, run the task, and then exit the root user. Because root was enabled, some users would simply log in as root and forgo a standard user account altogether. That's a security risk no one should take.
