TempleOS (a Song for Terry)

Summary

A hymn for Terry A. Davis (1969–2018), the programmer who spent a decade building TempleOS — a complete 64-bit operating system, written alone, ring-zero only, with its own programming language (Holy C) and a random Bible verse oracle he believed was God speaking directly to him. Davis had schizophrenia and was intermittently homeless in his final years; he died in 2018 after being struck by a train. The song treats his work with genuine reverence, holding his genius and his suffering together without resolving either.

Lyrics

[intro - spoken sermon by a preacher]
(Temple O.S. is a 64-bit)
(non-preemptive multi-tasking)
(multi-cored, public domain, open source, non-networked)
(ring-zero-only, single address space)
(PC operating system for recreational programming!)

[Verse 1 - The Man]
They said he walked with angels,
Or maybe with shadows in his mind.
A prophet with a keyboard,
Writing hymns in machine design.
He lived between two kingdoms,
One of earth and one unseen:
King James Version guiding his precision,
He crafted a temple of unique vision!

[Chorus - A choir harmonises in celestial style]
Temple O.S. a temple of light,
Six-40 by Four-80, each pixel so bright.
Holy C psalms on silicon stone,
God in the code, and the code all his own.

[Verse 2 - The Faith]
"The stone the builders rejected
has become the cornerstone";
So he built a holy altar
Out of circuits, bare and lone.
He said the Lord was speaking,
Through his random bible verse display,
Like a bush that burned with fire,
Yet was never burned away.

[drop]

[Verse 3 - The Struggle, with discordant digital delays]
But the prophets aren't always gentle,
visions don't always heal.
Schizophrenia's thorns still pierced him,
Yet he worked the sacred wheel.
A voice cried in the wilderness,
Through colors fierce and wild,
And though he was pursued by glowies
He sought to be the Father's child.

[Chorus — A choir harmonises in celestial style]
Temple O.S., a temple of light,
Self-hosted hymns in the dead of night.
No net, no chain, no borrowed frame,
Just one man's faith in God's own name.

[Bridge - The Code]
No Unix roots, no ancient tree,
Just desert winds and Holy C.
A flight sim, hymns, pixel rainbows,
Scripture whispered where the cursor goes.
Ring-zero freedom, nothing to hide,
A voice with angels at his side.

[Verse 4 - The End]
2018, a fateful train would take,
A soul too fragile the world could not remake.
But the temple stands as his legacy,
Its doors and source open for all of us to see,
And the digital hymns in its memory
Still whisper the code for eternity.

[Final Chorus]
Temple O.S., a temple of light,
Carved from struggle, from faith, from the fight.
Terry, your code, your spirit survives;
In every line, your temple's alive.

[flourishing end]

Detail

Terry Davis is a cult figure in programming communities — regarded simultaneously as a cautionary tale, a folk hero, and a genuine genius. TempleOS is technically remarkable: a complete operating system written alone, in a custom language, with its own compiler, kernel, filesystem, GUI, and applications. Davis believed God had specified the parameters: 640x480 resolution, 16 colours, and a single ring-zero address space as a metaphor for direct access to the divine without layers of abstraction.

The song treats his theology with the same seriousness as his engineering, which is the right call. Davis experienced his random Bible verse generator as genuine divine communication; whether this was psychosis, metaphor, or something else is not the song's business to adjudicate. "He lived between two kingdoms" neither pathologises nor romanticises — it describes.

The intro — a preacher reading the TempleOS technical specifications as if they were scripture — is the song's best formal move. Ring-zero-only, single address space, recreational programming: read with the right cadence, these are liturgy. The final chorus addresses Terry directly ("your code, your spirit survives") which the song has earned by that point.
