TempleOS was a free and open-source operating system designed by Terry A. Davis. It was released in 2013 and was known for its unique features and unconventional design.
One of the most striking things about TempleOS was its kernel, which was written entirely in Davis’s own programming language, HolyC. This language was inspired by C but had some unique features that made it well-suited for low-level system programming. Davis believed that HolyC was divinely inspired and that he had received instructions directly from God on how to create it.
Another distinctive feature of TempleOS was its user interface, which was designed to resemble the classic text-based interfaces of the 1980s and 1990s. It had a built-in text editor, compiler, and debugger, as well as a variety of other tools for system programming and development.
Despite its unconventional design, TempleOS gained a dedicated following among programmers and hobbyists who appreciated its unique features and the passion and vision of its creator. However, it was also criticized for its lack of support for modern hardware and for Davis’s controversial views on race and religion.
Tragically, Terry A. Davis passed away in 2018, and TempleOS is no longer actively maintained. However, it remains an interesting and unique example of what can be accomplished with determination, creativity, and a strong vision.
