Short notice, as it's today at 3PM Pacific:

I'm looking forward to learning more, but also seeing how Larry's making
the most of his post-Adobe career. I was glad to see him at the Computer
History Museum last year, with the same sparkle in his eye :)

Stay safe,

PS. The event link isn't resolving for me, so LMK if you make it:

Medley Interlisp is the environment from the old Xerox Lisp machines, which
> was spun out to a company called Envos, which then turned into Venue.

> It was once a commercial software development environment aimed at the
> 1980s AI market, and it contained many influential ideas. Notecards, for
> example, was a conceptual predecessor of Apple's Hypercard, and D-EDIT and
> S-EDIT are sort of the canonical ancestral structure editors. Masterscope
> and the "file package" included system-management tools that combined
> features of version control and build systems, with comprehensive cross
> referencing support.

> Medley was the latest release of the Xerox Lisp environment, before the
> whole environment was renamed Medley. It was originally written in
> Interlisp (a dialect separate from the MACLISP/Common Lisp tradition, with
> its own ancestry), but later, Common Lisp also became part of the
> environment. Medley includes WYSIWYG text editor (TEdit), email organizer
> (Lafite), performance tools (Spy) and many other libraries and user
> contributed code (from the 1980s).

> The 1992 ACM Software System Award, to Daniel G. Bobrow, Richard R.
> Burton, L. Peter Deutsch, Ronald M. Kaplan, Larry Masinter, Warren Teitelman

> for their pioneering work in programming environments that integrated
> source-language debuggers, fully compatible integrated
> interpreter/compiler, automatic change management, structure-based editing,
> logging facilities, interactive graphics, and analysis/profiling tools in
> the Interlisp system.

> At this point the base system is usable enough on 64-bit OSes and quite
> fast (A $40 pi runs Lisp > 150 times faster than a $30,000 Xerox 1108 in
> 1982).
