The notice of Paul Jackson’s presentation concerning his “set of .Net classes which provide APL functionality for the .Net programmer” to APLBUG April 1st, 2010 crossed my desk the same day I was flipping through a random selection of old I P Sharp newsletters. The last time I remember seeing Paul was about 20 years ago. I happened upon IPSA’s newsletter from 1980 where they announced Paul had climbed on board!
He still looks the same to me.
Of course, most APLers in Palo Alto are not affiliates of IPSA, Curtis Jones writes of Paul Jackson and Joey Tuttle back in the day,
Paul was the host to APL BUG meetings at the IPSA offices in Palo Alto for a large part of the 1980s, probably into the early 1990s. Joey probably remembers when the IPSA offices in Palo Alto closed. The scheme of getting takeout food to eat in the meeting room comes from the great assortment of restaurants along California Avenue. The offices were on California Avenue, then moved a couple of blocks away – but still an easy walk from the restaurants.
Nothing demonstrates the unique enthusiasm of the array language community like APLBUG, The APL Bay Area Users’ Group (The Northern California SIGAPL of the ACM). In fact, they jumped right in and gave me a momentous push when this project was an idea with no real substance.
In 1974, IBM moved its APL group to Palo Alto. Ken Iverson and Adin Falkoff stayed in Philadelphia, as did my father, Richard Lathwell. Ken and Richard were later to join I P Sharp Associates up here in Toronto.
