Zeit’s interactive visualization of the 2019 European election results

Zeit — the German newspaper — analyzed recent election results in over 80,000 regions of Europe. They discovered many patterns – from the radical left to the extremist right.

GoalKicker: Free Programming Books

This specific link has been on my to-do list for so-long now that I’ve decided to just share it without any further ado. The people behind GoalKicker, for whatever reason, decided to compile nearly 100 books on different programming languages based on among others StackOverflow entries. Their open access library contains books on languages from…

Screeps: An AI colony simulation game for programmers

A while back I discovered this free game called Screeps: an RTS colony-simulation game specifically directed AI programmers. I was immediately intrigued by the concept, but it took me a while to find the time and courage to play. When I finally got to playing though, I lost myself in the game for several days…

Debuggex: A regular expression testing tool

I came across this awesome regular expression tool I wanted to share. Debuggex allows you to interactively write, test and visually inspect what your regular expressions match in either Python, JavaScript, or Perl. Read more about regular expressions here, for instance their implementation in R.

Visualizing the inner workings of the k-means clustering algorithm

Originally, I wrote this blog to share this interactive visualization of the k-means algorithm (wiki) which I was all enthusiastic about. However, then I imagined that not everybody may be familiar with k-means, hence, I wrote the whole blog below.  Next thing I know, u/dashee87 on r/datascience points me to these two other blogs that had already…

7 tips for writing cleaner JavaScript code, translated to 3.5 tips for R programming

I recently came across this lovely article where Ali Spittel provides 7 tips for writing cleaner JavaScript code. Enthusiastic about her guidelines, I wanted to translate them to the R programming environment. However, since R is not an object-oriented programming language, not all tips were equally relevant in my opinion. Here’s what really stood out for me. 1….

dygraphs

Today I learned about dygraphs, a fast, flexible open source JavaScript charting library. As everything in JavaScript, the charts produced by dygraphs integrate completely in the webbrowser and are thus very functional and interactive. See, for instance, the below where the graph highlights the y-axis value for both time series in the graph based on the x-axis…

Bellwoods: A procedurally generated game in only 13 kilobytes

JS13K Games is a competition where developers are challenged to create an entire game using less than 13 kilobytes of memory. Creative developer Matt Deslaudiers participated and created Bellwoods: an art game for mobile and desktop that you can play in your browser. The concept of the game is simple: fly your kite through endless fields of colour and sound,…
