Trivial Solutions The LoseThos 64-bit PC Operating System Download LoseThos V8.00 (5.74 Meg) It's Free LoseThos is a 64-bit, multicored, multitasking, 100% open source, public domain, ring-0-only, single-address-map operating system for the PC. It requires a 64-bit x86_64 CPU and 512+ Megs of RAM. It does not have GPU acceleration, so I limit it to 640x480 16 color graphics. The vision for LoseThos is a 64-bit Commodore 64 that's a thousand times faster than the original and has a shell that is C/C++ instead of BASIC. It's for recreational programming. LoseThos is a secondary operating system because it doesn't have networking. Trivial Solutions makes LoseThos. The best example of a trivial solution is the fable that NASA spent millions on a space pen while Russia used a pencil. These are the trivial solutions that make LoseThos what it is. They are by design and if you reversed them, you'd have Linux. LoseThos is orders of magnitude simpler than Linux, only 129,739 LOC including a compiler! With LoseThos, "open source" is not a false promise that frustrates and breaks hearts. LoseThos has unmatched performance in some areas because it doesn't waste time with privilege level changes and it doesn't waste time modifying page tables. It can change tasks in half a microsecond. (All x86_64 or better CPU's are faster than 2 GHz.) Just remember that CPU protections only benefit you if you have malware or buggy programs. A home computer is not a 1970's mainframe.
