Wiring the Hopeful Brain in Lisp: Modeling 3D White-Matter Tractography and Deep Brain Stimulation in Coni

In neurosurgery, two millimeters is the distance between a life reclaimed and two years of silence.

For over two decades, Subcallosal Cingulate Deep Brain Stimulation (SCC-DBS)—pioneered by Dr. Helen Mayberg, Dr. Andres Lozano, Dr. Patricio Riva-Posse, Dr. Ki Sueng Choi, and colleagues—has offered a lifeline to patients living with severe, intractable Treatment-Resistant Depression (TRD). By implanting hair-thin four-contact electrodes into Brodmann Area 25 (BA25) and delivering continuous 130 Hz electrical pulses, clinicians watched patients who had failed every medication, psychotherapy, and electroconvulsive protocol experience a sudden lifting of visceral dread—and go on to achieve sustained, multi-year remission.

Putting a Lisp on a Diet: How We Cut Coni's Boilerplate in Half (and Taught the Linter to Bully Us Into Using It)

There is a polite fiction we Lisp programmers like to tell ourselves at parties.

While Python developers are arguing about significant whitespace and Go developers are typing if err != nil for the 4,000th time before lunch, we swirl our artisanal coffee and say: “Ah, Lisp. Pure S-expressions. Code is data. Zero syntax. The ultimate expression of human conciseness.”

And then you open a real, battle-scarred 500-line production file in Coni—specifically one that deals with messy real-world things like HTTP APIs, JSON payloads, environment variables, SSH tunnels, and LLM tool calls—and you are greeted by The Staircase of Doom:

The Shape of the Gap: Socrates, Aporia, and the Architecture of Unlearning in Coni

“Aporia teaches us that we don’t know what we thought we knew, and we are all the better for finding out. After all, it is better to have knowledge of our ignorance than to be ignorant of our ignorance.”
— Oscar Davis, What is the Socratic method? Could it be used to test students in an age of AI? (The Conversation, October 2026)

“Whatever inspiration is, it’s born from a continuous ‘I don’t know’… This is why I value that little phrase ‘I don’t know’ so highly. It’s small, but it flies on mighty wings.”
— Wisława Szymborska (Nobel Lecture, 1996)

OpenAI's New Decisions API vs. JEV & Julia-1: Building a 10ms-to-Cloud Reflex Cascade in Coni

Over the past two weeks, we have been obsessed with a single architectural thesis: autonomous agents should not use slow, token-dripping chat models to make bounded routing decisions.

First, we wired Coni’s Go-backed CSP channels into Ollama 0.35’s System One API to run TypeSafe’s JEV causal decision models (nimble and tev1). A week later, when Ollama choked on SupersonicLabs’ bidirectional ModernBERT architecture, we built a native 24-layer Julia-1 engine directly on Apple Metal MLX, hitting 10 milliseconds per inference in pure Coni.

The Case of the Phantom Megabytes: Developing Film Noir in Pure Lisp

It was late. The kind of late where streetlights reflect off wet asphalt and neon signs hum with an electrical buzz that vibrates straight through your teeth.

I was sitting in a dimly lit vinyl bar. You know the place: thousands of jazz records lining the walls floor to ceiling in wooden cubbies, amber scotch glowing in lowball glasses, and behind the counter, a bartender sporting a fedora silently cueing up a blue note pressing under the glint of a spinning disco ball.

Goodnight PowerPoint: We Built a Zero-npm Slide Deck Engine in Pure Lisp

Everyone who has ever had to give a technical talk knows the specific modern agony of preparing slides.

You start with noble intentions. You have interesting ideas, working code, and an architecture you are genuinely proud of. But the moment you open PowerPoint, you enter a spiritual wasteland. You spend 40 minutes fighting against automatic bullet indentation, wondering why moving a text box two pixels to the right just caused a table on slide 4 to collapse into an alternate dimension.
