TempleOS is an x86_64, multi-tasking, multi-cored, public domain, open source, ring-0-only, single-address-map (identity-mapped), non-networked, PC operating system for recreational programming. It sticks to common, 64-bit hardware instead of distinct drivers because you must shoot-the-moon. Also, redundancy and varied capabilities are unpleasant compared to everybody-has-the-same-thing.

    Wonderful bit of comp sci geekiness. Love it since I am a very long time comp sci geek. Good to see some grass roots programming still going on.

    Also good to see that this has as much in common with any current mainline OS out there as an aardvark has with a rutabaga. I am always a big fan of originality.

    Is it simplistic? Sure it is! It is not trying to be a mainstream desktop or mainframe OS. It is simply an OS that a guy wrote in his spare time as an intellectual exercise. And to that I say it is a fine effort.

    Will I be able to play Half-Life 3 with it?

    Indecipherable. Author must wear an aluminum foil cap.

    A hundred download here or there means nothing. I have a talking SETI. When I get out of prison, there will be 24/7 coverage of TempleOS on all stations in all countries. A hundred download, ridiculous. 600 million download will occur, instantly.
