When you're working with data — especially in analytics — you’re often dealing with tables: CSV files, Excel sheets, or exports from databases. To handle these kinds of tabular datasets easily and efficiently in Python, there’s a powerful library called Pandas. The name comes from “panel data”, but don’t let the academic term scare you off. In practice, Pandas is one of the most user-friendly and useful tools in data analysis.
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.
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.
Cloning a repository from GitHub isn’t just about “downloading files.” It’s a full-fledged connection to a project: you get not only the code but also the entire commit history, all the branches, and the ability to sync changes. In this guide, I’ll walk you through how it works, how to clone a repo in different ways, and what to do if something goes wrong.
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.
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.
VI is a powerful console text editor. It is deservedly one of the most popular tools in Unix systems. And all thanks to its speed and a huge number of text manipulation features. However, it can be a bit difficult to master. That's why we have collected the main commands of the Vi editor in this article.
The world of web development is constantly evolving, and choosing the right PHP framework is a critical step in the creation of any project. This overview will help you navigate through this variety and choose the best solution.
In this article, we will tell you how to work with variables and structures. This is especially useful material for novice users. Recall that the language has static typing. In Python, Ruby or JavaScript you will have to perform several correctness checks. Go avoids this problem.
We have already told you about the history of the Go programming language, its structure and syntax, now we can execute the simplest program on it, namely the classic Hello World. Ready? Then it won't take long to get the hang of it.
