If you are in the Toronto, Canada, area on Thursday 12 March, why not spend the afternoon (15:45-17:30 EDT ) at a panel discussion on the history of academic computing in Canada? Hosted by York University, APL is likely to feature – their “York APL” implementation helped spread APL’s academic use in the 1970s.
