In February 2014, a big bank in the Netherlands suffered from an internet banking malfunction which led many costumers to accidentally perform duplicate bank transfers.
AI thinks my dog is a Pig! Want to know why?

Applications of machine learning models are everywhere, with many online platforms and major science fields using tools relying on machine learning. Take, for example, image recognition and computer vision. But did you know that the results of supposedly perfect and accurate machine learning models can be deceived by slight perturbations in the data?
Can algorithms learn to price collusively?
This is a question I have been thinking about for the last two years. In this article, I will give a little overview of what I have discovered in that time.
MO-together and not alone! How networks can help fundraising in the no-profit sector

To make matters even more stressful, there are many routes to your destination, but you have no idea which one to select. Luckily, you have access to a navigation system that can help you in your route selection process.
How Aho and Ullman slayed the Dragon

Alfred Aho and Jeffrey Ullman received the 2020 A.M Turing Award for their contributions to computer science. Let’s explore how their contributions have shaped the principles, techniques and tools for writing compilers.
Enigma: a complexity titan

In times of war, secure communication can be the difference between life and death, or even winning or losing a war. The first to patent a rotor machine in Europe was Arthur Scherbius in 1918. Scherbius’ version of the rotor machine became a commercial success, unlike the other patented machines. Scherbius named his machine Enigma.
