Ken Thompson's 75 year project: A century of popular music in a jukebox [video]
I was at the talk, and it's strange this what people take from it. You should watch the whole thing and see what he built over years.I was a bit disappointed that most of the questions ignored his talk about a very cool jukebox he built and focused on OS drama.He built a jukebox with all hit songs he could find in it  1900-2000 and for prerecorded music, got a player piano and sheet music and midi and integrated the whole thing. Touch screens, voice activation and so on. Hardware and software and data hoarding project.He said he has massive cabinets of CDs, all the music he ripped and tested audio encoders with his own ears.Ken is 80, and still building cool side projects and scratching his own itch! That's the story.Be like Ken by building something cool, not by using whatever OS.
