BusConf - a FP themed (Open Space) un-conference taking place from August 1st to 3rd 2019 in Rueckersbach (de) close to the Frankfurt airport.
… not a traditional conference (http://www.bus-conf.org/format).
… open to anyone who wants to share, teach or learn about FP in any language at any level of expertise.
… a friendly, non-profit community-driven event
… not actually taking place in a bus - sorry to disappoint
Registration has already started, so if the above sounds interesting to you head over to http://www.bus-conf.org to find out more and register. You are welcome to also ask questions here of course.
