Mailcoach is an email platform by Spatie that comes in two formats: a cloud service and a self-hosted solution. In both cases, it covers several use cases at once, including marketing campaigns, automated email sequences, and transactional emails.
Zip is a command-line tool for compressing files and folders. Compression makes transferring and storing data faster and easier, and it’s handy for emailing. Unzip does the opposite—it extracts archives.
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.
Is your server slowing down, and you can’t figure out why? Logs show nothing, htop doesn’t help, and your website only loads half the time? That’s where Netdata comes in — a lightweight but powerful monitoring tool that shows you what’s happening on your system right now.
In this guide, we’ll walk you through installing Netdata, securing its web interface, and setting up alerts so you’re always aware of what’s going on with your server.
In Ubuntu 24.04, Snap is still a key part of how you install and manage software. It’s a flexible format that makes it easy to install apps, handle updates, switch between versions — and even remove Snap entirely if you want to. Here's a simple and practical guide to how it all works.
If you’ve ever tried installing Linux and ran into weird boot errors — especially when Secure Boot is involved — you’re not alone. In this article, we’ll break down what Secure Boot actually is, what shim files are, and why they sometimes get in the way of booting Linux — in simple terms, without diving too deep into technical jargon
If you really want to control which apps on your Linux machine connect to the internet, a traditional firewall might not be enough. What you need is OpenSnitch. Most Linux users rely on tools like iptables, ufw, or firewalld. They do a solid job, but they operate at the network level and don’t let you manage internet access on a per-application basis. That’s where OpenSnitch shines — it watches outgoing connections and lets you decide which applications are allowed to go online and which aren't. In this article, we’ll look at what OpenSnitch does, why it’s useful, and how to install and start using it.
Picture this: you're calmly working on your Linux machine — maybe installing updates, compiling a package, or just browsing the web — and suddenly the screen freezes. Then a wall of intimidating text appears: "Kernel panic – not syncing: Attempted to kill init!" Take a deep breath — no need to panic over a panic. Let’s break down what it is, how you can (safely) trigger one for testing, and most importantly, how to fix it when it strikes.
When you're setting up a server for your specific tasks, you want it to run fast and clean — without extra stuff getting in the way. But here's the catch: many modern Linux distributions, especially those using systemd, automatically start a bunch of services by default. Even the ones you don’t need. These background services can quietly eat up system resources — and sometimes even become security risks. Let’s go over how to find and disable services you don’t actually need on popular Linux distros like Fedora, CentOS, Ubuntu, and Debian.
