He has a good family too. He was a fun and engaging speaker, with publications like, "A Dialectic on Software Autocracy and Anarchy and the History of Unix and Vodka" preserved on his QEF Software INC site. I had this bookmarked at one time but QEF.com is now non responsive, there is an outline of QEF here. https://stellar.cleanscape.net/stdprod/qef/qefwhite/00_abstract.htm <https://stellar.cleanscape.net/stdprod/qef/qefwhite/00_abstract.html&ved=2ahUKEwiclJ6NpKDuAhXYHM0KHXu8AIMQFjABegQIBxAC&usg=AOvVaw3yCGBDN8f7li-3xX1jfn8X&cshid=1610794821685> l I do a fair bit of reading on different aspects of technology and I found David's style of mind-mapping relationships, within the context of office/software automation, quite interesting. I almost posted QEF info on, o1bigtenors thread about culling out redundancies in time and process management. The only conversation I ever had with David was brief and about tex foils and tcl/tk because I was writing a gif browser at the time, but I did go back to his site quite a few times when I was thinking about perspectives and I was looking to change how I was abstracting them. The wayback machine has the site and a list of publications. https://web.archive.org/web/20200111123852/http://qef.com/ > I miss him.
