All you need to get started — This post intends to be an introduction to the Go programming language, also known as Golang. Disclaimer I’m not an expert in Go. In fact, I’ve started learning about Go very recently. Therefore, take everything in this post with a pinch of salt. Then… why am I writing a post about…

It’s not just about coding — Rubber duck debugging Have you ever wondered why there’s a rubber duck on your colleague’s desk? If there’s no tub in your office, it may be because he’s rubber duck debugging. It has happened to all of us: you are stuck on a piece of code that you cannot get to work. You…

Try it yourself in this post! — First of all, what is a geometric fractal? A geometric fractal is a geometric shape with a repeating structure at different scales: it doesn’t matter whether you get closer to the image or not, you’ll always see the same pattern. …

Learn how to generate them — In this post, I’ll be showing how to generate a pseudo-random strings in Python. Let’s get started! The “random” module In the first approach, we’ll be using the random module. This module allows us to create pseudo-random numbers or sequences and can be useful for generating non-security-related strings. As we’ll see in the…

Master the basics — This post will be a very practical one, providing you with simple and quick tips to work with strings in Python. String multiplication Python allows multiplying not only numbers, but also strings! Repeat a string as simply as follows: >>> "a"*3 'aaa' >>> You may also multiply strings by a boolean value…

Get rid of that awkward tmp. — In this post, I’ll be showing 3 ways to swap two values without needing a third variable. Even though these approaches may (well, might) be applied in any language, I’ll be showing their implementation in Python. Swapped assignment This is probably the most widely known approach, which consists of assigning to each…

How does the GIF format work? — In this post, we are going to explore LZ78, a lossless data-compression algorithm created by Lempel and Ziv in 1978. As an example, the GIF format is based on LZ78. LZ78 takes advantage of a dictionary-based data structure to compress our data. …

Start the year off right. — In this post, I’ll be presenting 3 powerful libraries that you may not know about. Let’s get started! python-dateutil You’ve probably already used Python’s standard datetime module and, even though it’s already quite good in the most common situations, you’ve probably felt that it was missing something. Well, let me tell…

Reduce the complexity of your code. — In this post I’ll be talking about partial functions and how we can use them to make our code cleaner. What can partial functions do for us? A partial function allows us to call a second function with fixed values in certain arguments. For instance, we may have a function that computes an exponentiation. Then, we may…
