In 2008, I started django-simplewiki, which developed into django-wiki by sponsorship of MIT/edX. The project has been alive since then, and it should be able to maintain a decent level as a "batteries included" core application of Django.
The vision is to create a project that's more than a prototype, but represents incremental improvement and is something that's reliable enough to base other long-term projects on.
Most of my work revolves around computer reuse because I consider the mis-production and mis-use of ICT one of the biggest challenges that I can address as an ICT professional. By this, I mean that far too many people and companies replace their equipment prematurely, and far too little attention is given to the value and possibilities of having durable equipment rather than cheap disruption full of planned obsolescence.
In addition to that, FAIR works with the idea of equal access to knowledge, education, and the tools needed for this.
The end-result is that we collect the most easily accessible and high-quality fraction of e-waste in order to repurpose this for education.
ToughRoad is an educational, live role-playing and digital simulation game. It focuses on the global trade of coffee. I've made the digital platform, including a simulation of futures exchange.
It has been played with >5,000 students in Denmark, ~1,500 students in Norway, and premiered in Sweden where it's to roll out soon.
This means that as a software, it has endured for long-term support and a broad adaptation, not least multilingual.
The challenges in this project are the compromises between technical details and pedagogy, meaning that students have to acquire all their knowledge about the rules of coffee trade while they play. Thus, demands for user interaction are fairly high, although lots of work done in terms of printed materials and instructor training has been an essential key.
