About Me

alt text

Hi. Welcome to my blog. I’m an engineer from South Africa and I’m curious about the world. My hobbies include reading, long distance running, and complex origami (all the origami on this site is folded by me). I also occasionally work on my own engineering projects. My favourite place to be is in the middle of the bushveld.

I work as a software engineer. Previously I completed a masters in systems and control engineering at the University of Twente in the Netherlands. I also hold a bachelors in mechanical engineering from the University of the Witwatersrand in South Africa. In between my bachelors and masters I worked in telecommunications.

The subject matter of my posts is coding and mathematics, and occasionally physics. For a current list of posts, see here. Here is a list of possible future posts:

  • Electromagnetic waves and the internet: working in telecommunications taught me much about the infrastructure behind the internet. I’d like to explain that here. It always amuses me how people know that wi-fi doesn’t work several meters away from the router, but at the same time, are surprised to learn that most of the internet is not transmitted via wi-fi all the way from satellites in space! A similar article can be found here.
  • Counting routes for the multiple travelling salesman problem: this is a side problem from my thesis (I really should not have spent so much time on it).
  • Listing k integer partitions: another distraction side problem from my thesis.
