# Temple OS

Temple OS is a funny [operating system](os.md) made by a schizophrenic guy [Terry Davis](terry_davis.md) who has become a [meme](meme.md) and achieved legendary status for this creation in the internet tech circles as it's extremely impressive that a single person creates such a complex OS and also the OS features and the whole context of its creation are quite funny. It has a website at https://templeos.org.

According to Terry, God commanded him to write TempleOS and guided him in the development: for example it was demanded that the resolution be 640x480. It is written in [HolyC](holy_c.md), Terry's own language. The OS comes with GUI, 2D and 3D library, [games](game.md) and even a program for communicating with God.

Notable Temple OS features and programs are:

- [multitasking](multitasking.md) (non-preemptive)
- supported [file systems](file_system.md): [FAT32](fat32.md), ISO9660, RedSea (custom)
- HolyC compiler
- 2D/3D library
- oracle (communcate with God)
- [games](game.md)
- [IDE](ide.md) supporting images and 3D models embedded in text

In his video blogs Terry talked about how technology became spoiled and that TempleOS is supposed to be [simple](minimalism.md) and [fun](fun.md). For this and other reasons the OS is limited in many way, for example:

- no networking
- Only runs on [x64](x64.md).
- Only runs in 640x480 16 color display mode.
- single audio voice
- ring-0 only
- single address space
- multitasking is non-preemptive (programs have to yield CPU themselves)

Temple OS source code has over 100000 [LOC](loc.md). It is publicly available and said to be in the [public domain](public_domain.md), however there is no actual [license](license.md)/waiver in the repository besides some lines such as "100% public domain" which are legally questionable and likely ineffective (see [licensing](license.md)).
