Overview

Earliest known footage of Ivan Sutherland's MIT PhD work, Sketchpad, the first computer graphics system, with commentary by Alan Kay. It shows light-pen drawing with constraints in a short clip.

On Hacker News

HN points people to it as the canonical demo of early interactive graphics, constraints and objects, and as one of Alan Kay's favorite things to show.

Related to the visual simulations, one of Alan Kay's favorite demos over the years has been to show folks Sketchpad, [VIDEO] partly as a "this is what we were doing in 1962, you are now as far removed from that demo as that demo was removed from the year 1900 -- do you really feel like you've made the analogous/concomitant progress in programming?" ... and one of his points there was that a lot of programming acts as a "pop music" where you are trying to replicate the latest new sounds and marginally iterate on those, rather than study the classics and the greats and the legacy of awesome things that had been done in the past.

For "how things work", I recommend the book Code by Charles Petzold. After that, Jon Stokes's Inside the Machine will give a lot of details on CPU architectures up to Intel's Core 2 Duo. You can also try following along a computer engineering book if you want to go that low in detail with exercises, Digital Fundamentals by Floyd is a common textbook (I have an old 8th edition). History-wise, enjoy learning slowly because there's so much that even if you dedicated yourself to it you wouldn't be "done" any time soon! Some suggestions in order though: Watching The Mother of All Demos : [LINK] A short clip of Sketchpad presented by Alan Kay: [VIDEO] An article from the 40s that also inspired Engelbart: [LINK] The Information by James Gleick What the Dormouse Said by John Markoff The Psychology of Computer Programming by Gerald Weinberg Lastly, to mix up in whatever order you please, some paper collections: Object-Oriented Programming: The CLOS Perspective edited by Andreas Paepcke History of Programming Languages papers for various langs you're interested in, here's the set from the second conference in 1993 [LINK] but there have been further conferences to check out too if it's interesting Also all of the Turing Award winners' lectures I've read have been good [LINK] All that and some good recommendations others have given should keep you busy for a while!

So good. It never ceases to amaze me what could be done in such constrained systems (I guess it'll always look like that in retrospect). For anyone who has never seen it, Sketchpad, from the 60s: [LINK] Edit: With commentary from Alan Kay! [VIDEO]
