InfoQ has made available a video of a talk, “Forty Years of Fun with Computers”, by Dan Ingalls, who co-created Smalltalk at Xerox PARC, Squeak a few years later, and most recently, the Lively Kernel, a programming environment which runs within a web page. He’s one of those inventors and programmers whose accomplishments astound me, and who remains utterly humble about what he’s achieved.
The presentation includes some very cool demos of things they pulled of in Squeak and Lively Kernel. Don’t miss the part with the piston and the piano.
A must-see.
