Linux provides a wide range of system services (such as process management, login, syslog, cron, and more), as well as network services (remote access, email, printing, web hosting, data storage, file transfer, DNS, DHCP, and so on).
In essence, a service is a process or a group of processes that run continuously in the background, waiting for requests—most often from clients.
Linux offers several ways to manage services: start, stop, restart, or enable them to launch automatically at boot. Nearly all modern distributions rely on the same process manager — systemd.
When you want to check what’s going on with your system via terminal, the first command that comes to mind is usually top. But there’s a modern alternative — Btop++. It’s a powerful resource monitor for Linux that gives you detailed info about CPU usage, memory, disks, network activity, and running processes. Btop++ is written in C++ and is the successor to bashtop and bpytop, created by the same developer.
If you’ve ever plugged a USB stick into a Linux system and suddenly realized you can’t copy, delete, or change anything because the drive is mounted as read-only — you’re not alone. This is a pretty common issue among Linux users, whether you're on Ubuntu, Fedora, Arch, or another distro.
When working with code, things don’t always go according to plan. Maybe you committed the wrong file, made changes in the wrong branch, or just want to undo your last few steps. In cases like these, Git gives you a powerful tool — git reset. This command helps you roll back changes, clean up unwanted commits, or prepare your code for a new commit. It works with precision and flexibility: you can remove only the last commit and keep all your files as they are — or wipe the slate completely clean.
Is your site slowing down as traffic grows? That’s a common issue. One good marketing campaign or a mention on a news aggregator — and suddenly your server is struggling. Pages start loading slowly, 502 errors appear, and you're left wondering how to fix it. One of the simplest and most effective solutions is enabling caching in Nginx. It helps take the load off your server and makes your site feel noticeably faster.
When your project is small, Nginx handles things just fine — serving pages, images, scripts. But as traffic increases, each extra request puts more pressure on the system. That’s where caching steps in. It saves processed content and serves it again without redoing the work — saving time and resources.
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.
If you've ever tried to move multiple files and folders in Linux and encountered issues due to spaces in their names, you're not alone. Spaces in file and folder names can be a real headache, especially when working in the terminal or automating processes with scripts.
The Linux operating system is known for its security and flexibility, allowing users to configure the system to their needs. One of the useful features of Linux, as well as other Unix-like systems, is the support for multiple users.
SSH keys are a powerful tool for securing remote connections. They are used for authentication and data encryption when working over SSH. Unlike traditional passwords, SSH keys provide a much higher level of protection, as their mechanism avoids transmitting confidential data over the network.
