Step up your Coding Game

A friend of mine pointed me to this great website where you can interactively practice and learn new programming skills by working through small coding challenges, like making a game. CodinGame.com is an gamified learning community and website that allows you to learn new concepts by solving fun challenges. Pick from over 25 programming languages,…

Calibrating algorithmic predictions with logistic regression

I found this interesting blog by Guilherme Duarte Marmerola where he shows how the predictions of algorithmic models (such as gradient boosted machines, or random forests) can be calibrated by stacking a logistic regression model on top of it: by using the predicted leaves of the algorithmic model as features / inputs in a subsequent…

The Mental Game of Python, by Raymond Hettinger

YouTube recommended I’d watch this recorded presentation by Raymond Hettinger at PyBay2019 last October. Quite a long presentation for what I’d normally watch, but what an eye-openers it contains! Raymond Hettinger is a Python core developer and in this video he presents 10 programming strategies in these 60 minutes, all using live examples. Some are…

Neural Synesthesia: GAN AI dreaming of music

Xander Steenbrugge shared his latest work on LinkedIn yesterday, and I was completely stunned! Xander had been working on, what he called, a “fun side-project”, but which was in my eyes, absolutely awesome. He had used two generative adversarial networks (GANs) to teach one another how to respond visually to changing audio cues. This resulted…

Object-Oriented Programming with Java

Now that I’m slowly familiarizing myself in the world of Python, I am much more often confronted with classes and object-oriented programming (OOP). While R has its own OOP paradigms (yes, multiple, obviously, it’s R after all), I have never experienced the need to create my own classes. However, in other languages, like Python, Ruby,…

Getting started with Python in Visual Studio Code

After several years of proscrastinating, the inevitable finally happened: Three months ago, I committed to learning Python! I must say that getting started was not easy. One afternoon three months ago, I sat down, motivated to get started. Obviously, the first step was to download and install Python as well as something to write actual…

An Introduction to Docker for R Users, by Colin Fay

In this awesome 8-minute read, R-progidy Colin Fay explains in laymen’s terms what Docker images, Docker containers, and Volumes are; what Rocker is; and how to set up a Docker container with an R image and run code on it: On your machine, you’re going to need two things: images, and containers. Images are the definition…

A tiny guide to Variable Fonts & Color Fonts

So, you’ve probably never heard of variable fonts. Well, I sure had not when I first came across the concept a week or so ago. And I was shocked. This looked so cool. As I adjusted the size of my browser, the text and images adjusted itself along. As I made my Chrome window bigger,…
