Your site is running smoothly, everything looks tidy — until a new idea shows up. Let’s say you run a news site where every article has a featured image in a perfect 16:9 format. It all looks consistent and clean… until you start a new section. For example, a meme roundup. The problem? Meme images come in all shapes and sizes. And WordPress, trying to be helpful, crops them into your usual format — which totally ruins the visuals. Here’s the fix: instead of touching the main template, we’ll make a separate one. A simple copy where featured images show up as they are, no cropping. Fonts, layout, spacing — all of that stays the same.

How to Set Up a Terraria Server on Ubuntu

Terraria isn’t just a pixelated game — it’s a full-fledged adventure world where you can dig, build, fight bosses, and explore vast, randomly generated lands. It’s especially fun in co-op mode, and to enjoy it with friends without lag or limitations, the best option is to run your own server. In this guide, we’ll walk you through setting up a private Terraria server on Linux (specifically Ubuntu 24.04).

If you want to play The Forest with friends without lag or crashes, forget public servers — host your own! It’s easier than you think, and much more stable. In this guide, we’ll walk you through everything: from setup and configuration to mods and backups.

How to Turn a Python Script into an Executable File

When you write a script in Python, everything runs smoothly — because you have Python and all the necessary libraries installed. But if you want to run that script somewhere else (like sending it to a friend or running it on your work laptop), you'll run into a maze of installations and dependencies. Luckily, there's a way to bundle everything into one standalone file that works like a regular program. Here's how to do it.

How Load Balancing Works

When a server receives hundreds of requests per second, it's critical that the system continues to run smoothly. That’s where a load balancer comes in — a tool that distributes incoming requests across multiple servers to keep everything fast and stable. In this article, we’ll look at what a load balancer does, how it works, the methods and algorithms used in real-world infrastructure, and why cloud-based solutions are increasingly replacing hardware-based ones.

What Is Podman and Why Use It

Podman is a modern container management tool often seen as an alternative to Docker. It lets you run, manage, and group containers — but does so in a way that's simpler, more secure, and more flexible. Unlike Docker, Podman doesn’t rely on a background daemon. This means that if one part of the system fails, everything else keeps working. Another key feature is that containers can be run without root privileges, reducing system-level security risks. It’s also convenient that Podman is compatible with Docker — most familiar commands work in much the same way.
