California's Senate just closed out a fight that Linux maintainers and the EFF have been pushing since February. AB 1856 passed the Senate 39 to 0 on August 26, 2026, and the Assembly signed off on the changes the next day, sending the bill to Governor Newsom's desk with open source carved out of the […]

Accidentally deleted an important file on Linux? Don't panic, but stop using the affected disk as soon as possible. The more data Linux writes to it, the greater the chance that your deleted files will be overwritten and become much harder or impossible to recover. This guide walks you through the recovery process step by […]

LibreWolf vs Firefox comes down to defaults: both are built on the same Firefox codebase, but they make different choices out of the box. Firefox focuses on convenience and broad compatibility, while LibreWolf comes with stronger privacy settings, reduced telemetry, and more restrictive defaults enabled from the start. In this guide, we compare LibreWolf and […]

Choosing between RHEL and Debian for a server depends mainly on your support needs, budget, and how much control you want over the system. RHEL is a strong choice for organizations that need commercial support, long-term stability, and enterprise-focused tools, while Debian is well suited for users who prefer a stable, flexible, and community-supported Linux […]

The best online cron job tools for Linux generally fall into two categories. Category A includes cron expression generators and testers that help you create and verify the correct schedule, such as 0 22 * * *. Category B includes cron monitoring services that check whether your scheduled job actually ran and alert you when […]

Google Docs works fine until your IT policy, your client's compliance team, or your own gut says your documents shouldn't be sitting on someone else's servers by default. Every tool on this list runs on Linux, most of them self-hostable on your own VPS, a couple with a genuinely usable free cloud tier if you'd […]

xz compression in Linux is one of the easiest ways to shrink large files without giving up much on speed. It's a command line tool that uses the LZMA2 algorithm, trading a bit of extra CPU time for noticeably smaller files than gzip, which is why you will see it used for kernel tarballs, distro […]

The nmap command in Linux is the tool most admins reach for the moment they need to know what is actually alive and listening on a network. It scans hosts and ports, tells you what services are running, and can even guess the operating system on the other end. If you spend any time doing […]

Before you install Coolify on VPS, understand what you're actually getting: a bare VPS gives you the server resources, but you are responsible for managing applications, deployments, databases, SSL, and containers yourself. Coolify adds a simple web-based management layer on top of that VPS, giving you a more convenient way to deploy and manage applications […]

Choosing the best Linux distro for AI and machine learning is less about the desktop environment and more about hardware support, GPU drivers, package availability, system stability, and software compatibility. The right distribution can make it easier to set up NVIDIA or AMD GPUs, install AI frameworks, manage containers, and keep development environments reliable. In […]

⛶ × I used to tell people apt and dnf were basically the same tool wearing different hats. Then I spent a weekend migrating a small hosting client from an old CentOS box to Rocky Linux and watched dnf's dependency resolver refuse to touch a broken transaction that apt would have quietly limped through. That […]

⛶ × Have you ever run cd reports successfully, only to get "No such file or directory" when you run the same command from another folder? The reason is simple: Linux handles absolute and relative paths differently. Once you understand how each one works, navigating the filesystem becomes much easier and path-related errors are easier […]

⛶ × Zsh and Fish are two popular alternatives to Bash for interactive terminal use, but they take different approaches. Zsh focuses on flexibility and customization, while Fish emphasizes a polished experience with useful features built in. Our LinuxTeck community discussion showed a similar split: some prefer Fish for its simplicity, others choose Zsh for […]

⛶ × Linux networking problems rarely announce themselves clearly. A service may become unreachable, DNS may stop resolving, SSH may fail, or a firewall may silently block traffic. The application can appear broken even when the real problem is somewhere in the network layer. For DevOps engineers, understanding how to identify these failures is essential. […]

⛶ × Linux DNS troubleshooting usually starts the same way: "the site is down," and nobody wants to touch it. Nothing kills a Monday morning faster than realizing the outage is a DNS problem hiding in plain sight. Half the team assumes it's the app, the other half blames the network, and DNS quietly sits […]

⛶ × Linux provides several security mechanisms to control what applications, services, and users are allowed to do. Two of the most widely used mandatory access control systems are SELinux and AppArmor. Both can strengthen Linux security by restricting unauthorized access, but they use different approaches and are commonly associated with different Linux distributions. Understanding […]
