Here to try to make a difference with a bunch of different software tools, usually things that involve research in mathematics, optimization, climate change, and decision making somehow. Things like https://grønstrøm.nu to let you figure out when to turn on the tumble dryer, the electric car charger, or even the coffee machine. Or various open source packages and frameworks for various kinds of scientific computing over at https://github.com/fuglede/ If you think any of this is at all useful, a cup of coffee is hugely appreciated, keeps me motivated, and keeps the servers spinning. Thanks! Søren
