TempleOS (formerly J Operating System, SparrowOS and LoseThos) is a biblical-themed lightweight operating system designed to be the Third Temple prophesied in the Bible. It was created by American programmer Terry A. Davis, who developed it alone over the course of a decade after a series of episodes that he later described as a revelation from God.

The system was characterized as a modern x86-64 Commodore 64, using an interface similar to a mixture of DOS and Turbo C. The author proclaimed that the system's features, such as its 640x480 resolution, 16-color display and single audio voice, were explicitly instructed to him by God.[1] It was programmed with an original variation of C (named HolyC) in place of BASIC, and included an original flight simulator, compiler and kernel.

TempleOS was released in 2013 and last updated in 2017. It was received with largely favorable reviews in tech communities and Davis amassed a small online following. One fan described him as a "programming legend", while another, a computer engineer, compared the development of TempleOS to a one-man built skyscraper.[2] Davis died on August 11, 2018.[2]

Background[edit]

Terry A. Davis circa 2000

Terry A. Davis (1969–2018) began experiencing regular manic episodes in 1996, leading him to numerous stays at mental hospitals. Initially diagnosed with bipolar disorder, he was later declared schizophrenic and remained unemployed for the rest of his life.[1] He suffered from delusions of space aliens and government agents that left him briefly hospitalized for his mental health issues.[1][3] After experiencing a self-described "revelation", he proclaimed that he was in direct communication with God, and that God told him the operating system he built was for God's third temple.[1]

Davis began developing TempleOS circa 2003.[4] One of his early names was the "J Operating System" before renaming it to "LoseThos", a reference to a scene from Platoon (1986).[1] In 2008, Davis wrote that LoseThos was "primarily for making video games. It has no networking or Internet support. As far as I'm concerned, that would be reinventing the wheel".[5] Another name he used was "SparrowOS" before settling on "TempleOS".[6] In mid-2013, his website announced: "God's temple is finished. Now, God kills CIA until it spreads [sic]."[7] Davis died in a train accident on August 11, 2018.[2]

System overview[edit]

TempleOS is a 64-bit, non-preemptive multi-tasking,[8] multi-cored, public domain, open source, ring-0-only, single address space, non-networked, PC operating system for recreational programming.[9] The OS runs 8-bit ASCII with graphics in source code and has a 2D and 3D graphics library, which run at 640x480 VGA with 16 colors.[6] Like most modern operating systems, it has keyboard and mouse support. It supports ISO 9660, FAT32 and RedSea file systems (the last created by Davis) with support for file compression.[10] According to Davis, many of these specifications—such as the 640x480 resolution, 16-color display and single audio voice—were instructed to him by God. He explained that the limited resolution was to make it easier for children to draw illustrations for God.[1]

The operating system includes an original flight simulator, compiler and kernel.[4] One bundled program, "After Egypt", is a game in which the player travels to a burning bush to use a "high-speed stopwatch". The stopwatch is meant to act as an oracle that generates pseudo-random text, something Davis likened to a Ouija board and glossolalia.[6] An example of generated text follows:

among consigned penally result perverseness checked stated held sensation reasonings skies adversity Dakota lip Suffer approached enact displacing feast Canst pearl doing alms comprehendeth nought[6]

TempleOS was written in a programming language developed by Davis in C and C++, called "HolyC".[6] HolyC is a variation of C, developed by Davis as the programming language of TempleOS. It is used to interact with the shell, and to write and execute entire applications from the shell. The IDE that comes with TempleOS supports several features, such as embedding images in code. It uses a non-standard text format (known as DolDoc) which has support for hypertext links, images and 3D meshes to be embedded into what are otherwise regular ASCII files. A file can have, for example, a spinning 3D model of a tank as a comment in source code. Code can be JIT-compiled.[11] He ultimately wrote over 100,000 lines of code for the OS.[4]

Critical reception[edit]

TempleOS received mostly favorable reviews. Tech journalist David Cassel opined that this was partly because "programming websites tried to find the necessary patience and understanding to accommodate Davis".[4] TechRepublic and OSNews published positive articles on Davis' work, even though Davis was banned from the latter for hostile comments targeting its readers and staff.[4] After Davis' death, one fan described him as a "programming legend", while another, a computer engineer, compared the development of TempleOS to a one-man-built skyscraper.[2]

In his review for TechRepublic, James Sanders concluded that "TempleOS is a testament to the dedication and passion of one man displaying his technological prowess. It doesn't need to be anything more."[6] OSNews editor Kroc Kamen wrote that the OS "shows that computing can still be a hobby; why is everybody so serious these days? If I want to code an OS that uses interpretive dance as the input method, I should be allowed to do so, companies like Apple be damned."[4] In 2017, the OS was shown as a part of an outsider art exhibition in Bourogne, France.[12]
