Let’s be honest — no server runs without errors forever. No matter how perfectly you configure it, sooner or later something will go wrong. Maybe a file won’t be found, a script will fail, or a resource becomes unavailable. The key is not to panic, but to catch the issue as early as possible so you can fix it right away. But who really wants to keep staring at logs in the terminal all day, searching for errors manually? Wouldn’t it be much nicer if your server could just send you a message on Telegram the moment something breaks?
Let me show you how to set that up in just 15–20 minutes.
When you encounter a bug in Linux or try to explain what went wrong, the easiest thing to do is to show terminal output. Especially if you're asking for help on a forum, discussing a bug with a colleague, or sending a report to a developer. No one likes to copy kilometers of output manually, and it is a questionable pleasure to parse such sheets. In such cases, termbin - a simple and convenient tool that allows you to share output from the terminal literally in a couple of clicks - comes in handy. It creates a short link that shows the whole log at once.
After the end of CentOS 7’s lifecycle (EOL on June 30, 2024), the official repositories were disabled, and systems can no longer receive updates. However, Red Hat provides archived repositories via Vault, which can still be used to install packages. Vault link: https://vault.centos.org
Transferring files from your computer to a remote Windows server is a pretty common task. Usually, it’s simple: copy the file on your PC, paste it on the server — and you’re done. This method is handy for quickly sharing text, images, or documents.
But what if you need to transfer data directly from a USB stick connected to your local computer? That’s where USB passthrough tools come in. In this guide, we’ll show you how to set up USB passthrough on both Windows and macOS, making file transfers easier and faster.
In this detailed guide, I’ll show you how to set everything up. It works for almost any distribution — Ubuntu, Debian, Mint, Fedora, Arch, and others.
Rsync (Remote Synchronization) is a command-line utility designed for synchronizing files and directories across different storage systems. Unlike regular copying, Rsync transfers only the modified data, saving both time and bandwidth.
Tiling window managers offer a convenient alternative to traditional graphical environments by automatically arranging windows without overlapping. This allows for maximum screen space utilization and simplifies multitasking. Instead of the usual mouse-driven interaction, everything is controlled via keyboard shortcuts, speeding up workflow and making the system more responsive.
Thanks to their lightweight nature and flexible customization, tiling window managers are especially popular among programmers, system administrators, and minimalism enthusiasts. They consume fewer resources, run faster, and are better suited for widescreen displays. However, this approach requires some adjustment—lack of conventional window control buttons and the need for manual configuration might deter beginners. Nevertheless, for those open to experimentation, tiling window managers provide a completely new level of comfort and productivity.

When working in Linux, the need to rename multiple files at once often arises. Basic tools like mv and rename can handle this task, but they require writing complex commands or scripts for batch processing multiple files. If you need a quick and convenient way to rename multiple files simultaneously, the powerful tool mmv comes to the rescue. It significantly simplifies the process and allows you to set flexible filename templates.
