Note: The slides are in English, but the talk is in Danish. Click through to get to the video, then register to download the slides in PDF. Toit is Lars Bak and Kasper Lund's brand new programming language and software platform for small IoT devices. There's very little else I can find about it online; it was publicly unveiled in this session: https://di.ku.dk/english/event-calendar-2018/dsfd-talk-lars-bak/ https://di.ku.dk/english/event-calendar-2018/dsfd-talk-lars-... I can't find an online recording of that, if there is one.
