The computing world lost one of its great minds and true pioneers yesterday. Douglas Engelbart passed away at age 88, just over a half-century after he joined the Stanford Research Institute (SRI) -- the place where much of his ground-breaking computing research would take place. Among his (and his research team's) many inventions made at SRI are the mouse, bitmapped screens, hypertext, networked computers and elements of a modern, windowed GUI. Should you be among those unfamiliar with his work, we've included a video of his epic and appropriately named "Mother of All Demos" that he gave in 1968 to introduce many of his computational contributions to the world. Tip of the cap, Mr. Engelbart. You will be missed, but assuredly not forgotten.
