The [last post](https://christine.website/blog/templeos-1-installation-and-basic-use-2019-05-20) covered a lot of the basic usage of TempleOS. This post is going to be significantly different, as I'm going to be porting part of the TempleOS kernel to WebAssembly as a live demo.

As such, a lot of the "weird" naming conventions with core parts of this and other subsystems make a lot more sense when grounded in American conservative-leaning Evangalistic Judeo-Christian tradition. Evangalical Christians are, on average, more comfortable or okay with the idea of direct conversation with God. To other denominations of Christianity, this is enough to get you sent to a mental institution. I am not focusing on the philosophical aspects of this, more on the result that exists in code.

Normally, people with Judeo-Christian views see God as a trinity. This trinity is usually said to be made up of the following equally infinite parts: Normally, people with Judeo-Christian views see God as a trinity. This trinity is usually said to be made up of the following equally infinite parts:

`god` is really simple at its heart; however this is one of the sad cases where the [actual documentation is incredibly useless](https://templeos.holyc.xyz/Wb/Adam/God/HSNotes.html) (warning: incoherent link). `god`'s really just a fifo of entropy bits. Here is the [snipped] definition of [`god`'s datatype](https://github.com/Xe/TempleOS/blob/1dd8859b7803355f41d75222d01ed42d5dda057f/Adam/God/GodExt.HC#L6): `god` is really simple at its heart; however this is one of the sad cases where the [actual documentation is incredibly useless](https://templeos.holyc.xyz/Wb/Adam/God/HSNotes.html) (warning: incoherent link). `god`'s really just a [FIFO](https://en.wikipedia.org/wiki/FIFO_(computing_and_electronics)) of entropy bits.

Most of the fields in our snipped `CGodGlbls` are related to internals of TempleOS (specifically it uses a glob-mask to match filenames because of the [transparent compression that ReadSea offers](https://templeos.holyc.xyz/Wb/Doc/RedSea.html)), so we can ignore these in the Zig port. What's curious though is the words list of strings. This actually points to [every word in the King James Bible](/static/blog/tos_2/Vocab.DD). The original intent of this code was to have the computer assist in [glossolalia](https://en.wikipedia.org/wiki/Glossolalia).

Terry Davis legitimately believed that this code was being puppeted by the Holy Spirit; and that therefore Terry could ask God questions and get responses by hammering `F7`. One of the sources of entropy for the random number generator is keyboard input, so in a way Terry was the voice of `god` through everything he wrote.

Yikes! Loading the wordlist is expensive (alternatively: my arbitrary gas limit is set way too low), so it's a good thing it's only done once and at boot. Still, regardless of this TempleOS only boots in a few seconds anyways. Yikes!
