For a software developer, learning to work with Git is essentially a requirement that comes with the job description. Working with local and remote repositories, committing changes, and managing branches: these are some basics of Git you have to know like the back of your hands.

But beyond these basics, Git provides more advanced commands to make your life easier. They can improve your productivity and solve some not-so-uncommon problems you encounter when collaborating on a project with tens and hundreds of other developers. …

For something that is theoretically so simple, vertically centering elements in CSS is not the easiest task to accomplish. This statement was especially true before browsers started supporting modern additions to CSS like flex and grid.

In this article, we are going to discuss some older tricks and more modern methods developers use to vertically center content in CSS. Since each solution has its limitations, it doesn’t hurt to know every one of these methods to find the right solution in different scenarios.

Let’s get started!

If You Know the Height

One of the older tricks of CSS is centering an element vertically with the…

Javascript syntax and built-in methods allow us to cut down a lot of unnecessary lines in our code and write short, easily readable code. In this post, we are taking this simplicity another step forward to see where you can write one-line solutions to some common use cases and problems you’d encounter in web development. Don’t hesitate to steal these 15 Javascript one-liners to write quick and simple code for your applications.

Reverse a String

You can reverse a string in one line using split, join, and reverse methods.

const stringReverse = str => str.split("").reverse().join("");stringReverse("Welcome to Javascript")

Docker has become a tool that developers can’t live without in less than a decade since its release. Docker provides lightweight containers to run services in isolation from other processes in the system. If you haven’t yet been properly introduced to Docker, follow our introduction to Docker guide before continuing with this tutorial.

In today’s tutorial, we are going to learn how to containerize applications that require more than one Docker container with Docker Compose. Though it’s possible to set up this system with only Docker, we can complete this task more easily and efficiently using Docker Compose.

Let’s get…

I often hear or talk to people who want to get into tech, who want to learn to code, but they are terrified of its idea. It is common for people to think that to be a programmer, a web developer, you have to be a computer nerd, genius, or have some kind of innate talent for computer science, and it couldn’t be any more wrong.

Sure, computer science is a super…

Google has become so integral in our lives that we now use the verb “Google” to refer to the action of using this search engine giant. Using a few chosen keywords, you can find everything from the nearest grocery store to the latest developments in the world.

Sometimes, though, the magic of Google fails to give us the type of results we are searching for. You try different combinations of keywords and go deep into the search results but still fail to find what you want.

But did you know that Google provides options to refine your search and filter…

There’s more than one way to solve a problem, but not all of them are the best. Not every solution is capable of efficiently using our resources. Therefore we need to find the best, most efficient solution to a problem before taking action.

In programming, we can’t leave the mechanism of finding the best solution, the best algorithm, to guesswork. We need a clear standard to evaluate the efficiency of solutions. This is where the concepts of time and space complexity step in. They help us determine the algorithm’s efficiency based on the required resources.

In this article, we are…

Folium is a Python package that combines all the spectrum of tools Python offers to manipulate data with the Leaflet JavaScript library to create rich and interactive maps.

As usual for my articles, I’m providing a Google Colab Jupyter notebook with all the code and results.

Create a Basic Map

Before we start building anything, let’s install some libraries that we will be using throughout the tutorial. You can use any packaging tool. I’ll provide the examples for Pipenv and for pip prepending !, so that it works on Jupyter notebooks, like Google Colab.

pipenv install folium pandasOr!pip install folium pandas
