Stephen Taylor of the Iverson College is putting together a celebration of the live and notation of Ken Iverson.
This event is free but requires registration, so if you'd like to attend, please go to the link and register. There are a number of renowned members of the array programming community that are going to give some thoughts on Ken and "Iverson Notation" (AKA, APL, K, &c.).
In addition, there is a panel discussing the future of the notation, and I'll be on that. There will also be a Q&A time.
I look forward to seeing you there if you can make it!
