Forwarding a link to a compiler book posted on OhmLand by Patrick Dubroy. Along with a few more links to some stuff that I think is easy to read and understand.

Fundamentals of Compilers

New Alan Kay talk — 75 Years of Graphical User Interfaces. It's a tour of classic works — Sketchpad, GRAIL, Mother of all Demos, formation of PARC, Dynabook, Smalltalk, Negroponte's work on spatial UIs, Etoys, etc. — with light commentary and context.

Includes a video clip of GRAIL that I hadn't seen before. It's a node-wire (esq) programming system that visualizes execution by flashing the nodes, and it gives you control over the rate of execution. Wild.
