At Dyalog '18

Roger Kwok Wah Hui (December 29, 1953 - October 16, 2021[1]) was a computer scientist and co-developer of the programming language J, and later Dyalog APL. He ran and maintained the Jsoftware website.

Roger Hui's Iverson Award

History

Hui's work was described at the APL85 conference in a paper, "DESIGN: A Financial Modelling System", written jointly with his supervisor, Fred Appleyard. The basic objects in the system were in "Direct Definition" (Iverson, 1976, 1980), and Falkoff and Iverson's The Design of APL was cited. Hui left Alberta Energy shortly after being promoted to a non-APL and non-programming position, and was out of work, and had no access to computers, from September 1985 to April 1986. This gave him plenty of time for intense study of Iverson's Rationalized APL (1983) and A Dictionary of the APL Language, as it was then named. In 1996, Hui received the Iverson Award for his work on the design, implementation, and commercial development of J.
