A few days ago, I came across a CentOS 8 32-bit distro and decided to test it on an old 32-bit machine. After booting up, I realized there was a bug causing the network connection to drop. Every time I rebooted, I had to manually bring the network back up, which led me to wonder: How can I automate this process with a script that runs every time the system boots?

The solution is straightforward, and today, I’ll show you how to do this using systemd service units, but before we jump into that, let’s first take a quick look at what a service unit is and how it works.

Debian GNU/Linux is the backbone of several popular Linux distributions like Knoppix, Kali, Ubuntu, Mint, and more. One of its strongest features is its robust package management system, which makes installing, removing, and managing software a breeze.

Debian and its derivatives use a variety of package managers such as dpkg, apt, apt-get, aptitude, synaptic, tasksel, dselect, dpkg-deb, and dpkg-split. each serving a different purpose.

Whether you’ve heard it thrown around in a meeting, stumbled across it while setting up your Wi-Fi, or are just trying to figure out why your printer won’t connect to the network, subnet masks are all around you. We’re going to break this down together. By the end, you’ll know what a subnet mask is and why it matters to your everyday life—whether you’re a business owner or just someone who uses the Internet to work.

Here’s the quick version: a subnet mask is like a filter that helps your devices figure out who’s on the same network as the device. That’s it in a nutshell.

The long version is that a subnet mask defines the local network that isn’t part of the internet. These devices on the same network and subnet mask are able to communicate directly with one another without communicating to the gateway (internet). This has great privacy and performance benefits.

Ubuntu 20.04 LTS (Focal Fossa) has been a reliable and solid operating system for many users. However, as we move toward the end-of-life (EOL) for Ubuntu 20.04 LTS, it’s time to think about upgrading to the next Long-Term Support (LTS) release. Ubuntu 20.04 LTS will no longer receive standard updates after May 31, 2025.

Luckily, Ubuntu 24.04 LTS (Noble Numbat) has already been released and is ready for users to upgrade to. But here’s the catch: upgrades between Ubuntu versions are sequential, which means you cannot directly upgrade from Ubuntu 20.04 LTS to Ubuntu 24.04 LTS. Instead, you need to go through Ubuntu 22.04 LTS first.

AUTOSEL is a tool that is used to find kernel patches that should be considered for backporting into the stable releases. Sasha Levin has announced a new and completely rewritten version of AUTOSEL for those who would like to play with it.

Unlike the previous version that relied on word statistics and older neural network techniques, AUTOSEL leverages modern large language models and embedding technology to provide significantly more accurate recommendations.

Neptune is a GNU/Linux distribution for desktops. It is based on Debian's Stable branch, except for a newer kernel, some drivers and newer versions of popular applications, such as LibreOffice. It also ships with the latest version of the KDE desktop. The distribution's main goals are to provide a good-looking general-purpose desktop with pre-configured multimedia playback and to offer an easy-to-use USB installer with a persistence option.

MODICIA O.S. is a Linux multimedia distribution designed primarily for musicians, graphic designers and video makers. It is based on Debian's "stable" branch, but uses the Cinnamon desktop and a recent Linux kernel. MODICIA O.S. comes with a set of carefully-selected, open-source multimedia software and tools, such as Audacity (audio editor), Brasero (disc-burning utility), Cheese (webcam application), Curlew (multimedia converter), GIMP (graphics editor), HandBrake (video transcoder), Kdenlive (video editor), MediaInfo (tool that provides technical data about media files), mpv (media player), Peek (animated GIF recorder), RawTherapee (photo processor), XnView (image viewer), and many others. The distribution also integrates the OnlyOffice software suite for general office tasks.

The disclosure of the Spectre class of hardware vulnerabilities created a lot of pain for kernel developers (and many others). That pain was especially acutely felt in the BPF community. While an attacker might have to painfully search the kernel code base for exploitable code, an attacker using BPF can simply write and load their own speculation gadgets, which is a much more efficient way of operating. The BPF community reacted by, among other things, disallowing the loading of programs that may include speculation gadgets. Luis Gerhorst would like to change that situation with this patch series that takes a more direct approach to the problem.
