Whitney and I both worked in the 1970s for I.P. Sharp Associates, which used an email system written beautifully in APL by Leslie Goldsmith. Most user names were simply our initials. Ian Sharp was IPS, Leslie LHG, and Arthur ATW. (Middle name Taylor.) I’ve been SJT ever since (including to two wives) but was not smart enough to grab the domain: see 5jt.com.
While I’m learning kdb+, Dyalog remains my favourite language for hacking and is likely to remain so for much of the publishing work I do, because of its solid UTF-8 support.
Iverson was on to something with his iterators. I am still getting insights decades later. When I use control structures like for-loops (even in APL) it feels like talking with my thumb in mouth.
