First of all, let’s be clear. The goal of this article is to ** briefly introduce** how to use Julia for analyzing graphs. Besides the many types of graphs (undirected, directed, bipartite, weighted…), there are also many methods for analyzing them (degree distribution, centrality measures, clustering measures, visual layouts …). Hence, a comprehensive introduction to Graph Analysis with Julia would be too large of a task.

Therefore, this tutorial focuses on **undirected weighted graphs,** since they encompass weightless graphs, and are* usually more common than directed graphs*¹.

Almost every package you will need can be found in the JuliaGraphs Project. The…

So perhaps you decided to try Julia, and you are finding it quite amazing. You like how easy it is to do linear algebra, to vectorize functions, to do meta-programming… But there is one thing that is bothering your. The precompilation time!

Every time you start a new Jupyter Notebook (or restarts your kernel), the time it takes to precompile “simple” packages, such as Plots.jl, is quite “large”, or at least, quite annoying. Well, recently I was introduced by a friend to a package called PackageCompiler.jl. …

**Flux.jl**** **is the most popular Deep Learning framework in Julia. It provides a very elegant way of programming Neural Networks. Unfortunately, since Julia is *still* not as popular as Python, there aren’t as many tutorial guides on how to use it. Also, Julia is improving very fast, so things can change a lot in a short amount of time.

I’ve been trying to learn **Flux.jl **for a while, and I realized that most tutorials out there are actually outdated. So this is a brief updated tutorial.

So, the goal of this tutorial is to build a simple classification Neural Network…

If you are developing a new package for Julia, you might’ve followed the steps in **this article**, and is now wondering how to create the documentation for your package. Well, this is what this article is for. Here, our new package is also called VegaGraphs.jl, which is a package that I’m developing at the moment.

In this tutorial I’ll be using the package Documenter.jl together with the GitHub Actions plugin. The Documenter.jl package will help us create the documentation, and the GitHub Actions plugin will create a bot for us that will publish our documentation on our GitHub page.

First…

We’ll show step-by-step how to develop your first package in Julia. To do this, we use the very useful PkgTemplate.jl, and we base our Tutorial on this guide by Quantecon and this video by Chris Rackauckas.

First things first. Start by creating the folder to store your package. In our case, we’ll be creating a package named “VegaGraphs”, which is a package that I’m developing. So, inside this folder, open your Julia REPL and install PkgTemplate.jl.

An easy setup for Vim as Julia IDE (on Ubuntu)

As someone who has been a Vim user for years, I can confidently say that Vim is highly addictive. Once you get used to it’s shortcuts, editing code without it becomes unbearable. Although many tutorials exist on how to setup a Vim IDE for Python and other languages, no tutorial seems to be available for using Vim with Julia. So this might be a first.

By no means this article is comprehensive, I intend to present a very neat and fast way of using Vim with Julia. Note that there…

There are several ways to create your personal blog on the web, but not as many alternatives when you want to focus on technical subjects and want to write mathematical equations. In this brief article, I explain how you can use GitHub with Jekyll to create your personal blog with MathJax, so you can write beautiful equations using Latex notation. Note that this tutorial is written for Ubuntu, but can easily be adapted for a different OS.

In this tutorial, I will assume that you now what GitHub is, and that you can use it to host your personal website…

Installing Julia on Ubuntu is very straightforward. As anything on Linux, there are several ways to do the installation.

This is the first way, and it is the easiest. Just open the terminal and run

`sudo apt-get install julia`

The problem with this method is that you don’t get the latest stable version for Julia. In the time I’m writing this article, the Ubuntu repository contains the version 1.0.4 for Julia, while the current stable version is 1.5.2.

So this is not the method I recommend!

First, go to the Julia website download page. There, several ways to run Julia…
