Dabbling in text mining to study ‘othering’ on Bonfiire Stellenbosch

Background For my Honours research project this year, I analysed ways of increasing user participation in blog-based social networks. My case study was Bonfiire, a multi-community network for discussion and debate, that I co-founded with a friend in 2012. Since the public launch of Bonfiire Stellenbosch (our first community, targeted at Stellenbosch University students and [...]

Predicting the future with Machine Learning

The future is uncertain. Luckily by using some machine learning ‘black magic’ we will look into ways to predict the future. Hopefully in the blog post I can demystify some of the magic. Predicting the future, or to be more specific, Forecasting the future has been one of man’s fascinations for centuries. From ancient Babylon’s forecasters, weathermen [...]

Web Development – A Useful Skill

Why I started web development I’m a person that loves coming up with new ideas. My friends and family know this all too well. From drive-through grocery shops to fully automated peer-to-peer community courier services. Doesn’t matter how absurd, I just like new ideas. The problem is implementing these ideas. They usually cost a lot [...]

Struggles with GPUs and Ubuntus

Over the last year or so I’ve been working on Ubuntu OSs, conducting my research and writing my thesis. While writing the thesis isn’t an issue when it comes to hardware technicalities, I cannot say the same for the coding side of my Master’s. My research primarily focuses on optimizing simulations based on cellular automata, [...]

Sound Synthesis, an Overview

Group-based cryptography

In this blog post I will discuss the mathematical concept of a group, and I’ll give an example of an actual cryptosystem based on groups. I’ll try to keep the mathematical jargon to a minimum, and give illustrative examples where possible. Group theory 101 A group is a very general mathematical structure defined as follows. [...]

Fairness in e-commerce, sport and food

The theme of fairness has come up in very different contexts since my reading recently shifted away from being strictly thesis-centered. Of course, life isn’t fair and what is perceived as fair differs from person to person. That said, I have often wondered whether greater fairness is a hallmark of a more sophisticated or merit-driven [...]
