Download and install Julia on Windows, Mac and Linux the easy way — For a long time, the recommended way to install Julia was to go to Julialang.org, download the latest executable and run it. It’s still listed as the recommended way on the official website, but I argue there’s a better way. If you ever wanted to try out Julia for your…

Get a sound notification when your script is done — A long long time ago, I used to use R. Sometimes I would have functions or processes that take ages to complete, so I would wander off and do something else on my computer while waiting for the results. The problem was that I never knew when the script would…

The easiest way to make your code faster: ThreadsX.jl I have been following the Julia language since around 2014 or so. One of the most enticing things about Julia is that it was built for multi-core machines from its inception (using joblib in Python is such a nightmare…). …

Some cool features of the Julia language — I used Exercism to learn more Julia and found some useful tricks and tips on the way. Read on and see how many of these you already know. I started dabbling with Julia back in 2014 and have been on and off it ever since. Always wanted to use it…

Keep an eye on your for loops — Did you ever have the feeling that a function is just too slow? Did you often find yourself frustrated because you can’t see the progress your function is making? Fear not, we have progress bars! …

Everything you need to know about Google BigQuery User-Defined Functions — Google Cloud’s BigQuery is an awesome tool for data analytics and even machine learning. It comes with a load of useful functions right out of the box, but if you want to really dive into BQ you will at some point need to get comfortable with User-Defined Functions. …

Using Julia to play around with shapes and pies — I thought a lot about what to post on π day (March 14th). I’ve already written an article about estimating π with Monte-carlo methods here, so I couldn’t do that again. Then I remembered that back in high school we were shown a different way of estimating π: by using…

Use dynamic programming to make your functions faster — Memoization is a simple trick in programming where you reduce the amount of computation required by remembering some intermittent results. Here I’ll show you how to do this in Julia the easy way. 🙏 Huge thank you to the folks who made Memoize.jl Check out the repo here. Be naive We will…

Beginner’s tutorial without any external data — The first rule of machine learning should be that you should not use machine learning. What I mean is that if you have a new project, try to solve it without machine learning. ML is expensive, hard to monitor, maintain and run, not to mention Data Scientists can be expensive…
