Captain's log / infrastructure desk / fabrication bay
Field notes on compute, markets, and machines.
Sentimark is my public notebook for AI economics, agent behavior, GPU infrastructure, 3D-printed optimism, and the occasional sci-fi-shaped warning label.
Super TechThe If-Statement Retirement Plan
How I keep collapsing pages of slow, branchy decision logic into one register of bits and a Hamming distance. A love letter to approximate membership queries.
VoxellLegal First. Optimal Next.
Six weeks of a GPU router refusing to converge, a notebook full of labeled failures, and the afternoon 799,403 nets went legal on the card under my desk.
Super TechPushing the Featherweight Edge: Real-Time WebSockets Without a Server
Our lightweight, offline-first pattern goes real-time. By pairing low-latency Edge KV with an in-memory Durable Object sync broker, we get sub-100ms multi-device updates with zero client dependencies, zero backend processes, and zero database writes on the hot path.
VoxellI Bet Everything on Eight Weeks
A solo founder, one cluster, the largest research labs in the world, and a public scoreboard that doesn't lie.
Super TechThe Featherweight Pattern: Cross-Device State Without a Backend
A static site, a low-latency key-value store at the edge, and local-first client hydration make a whole class of web apps faster and lighter than reaching for a backend. Where the pattern fits, how it works, and the JSON-vs-binary numbers on whether the payload should ever be binary.
FoodieThe Berm, the Burn, and the Banana: Heat-Beating Comfort in Northern Sac
Riverside living, minus the river view. A red-tomato harvest, a lesson in suckers, slightly chilled Cabernet against the NorCal burn, and Grandma's pot roast reheated in her honor.
Voxellkill -9 Is a Feature: Auto-Healing a One-Box ML API Without Root
One box, one 8B model, one reviewer about to reproduce our MTEB numbers, and no sudo. How I made an embedding endpoint quietly fix itself for 72 hours with systemd, a probe that does real work, and the one signal that counts as 'unclean.'
FoodieA Late-Spring Tuscan Evening
A romantic dinner for two: burst garden-tomato and mushroom pasta, sous-vide chicken, a Lava Cap Chardonnay, and a three-act night. Rave reviews, generously assisted by the wine.
MindfulnessMindful by the River
A practical, evidence-backed guide for easing persistent worry and anxiety with mindfulness-based cognitive therapy practices.
FamilyRoute of the Postman
A Costner-themed family dispatch through California and Oregon, with pets, two charging stops, Eugene days, and the long road home.
Super TechMonetizing a Defect
How Anthropic's pricing structure turned a known model limitation into a billable feature, and what it signals about the AI subscription era.
FamilyWhen Big Boy Came Through Marysville
A field note from the afternoon Union Pacific Big Boy No. 4014 came through Marysville with steam, noise, friends, family, and a backyard beer afterward.
VoxellHard Negation
Why negation still breaks retrieval systems, and why hard negatives need to be harder than the word not.
Super TechA Speed Nerd Met spaCy
How a small Rust and PyO3 crate made one POS-window scoring loop roughly 1,500x faster without pretending to replace spaCy.
VoxellWhy Forge
Why another embedding engine is worth building when retrieval quality, transport shape, and trust boundaries decide what an AI system is allowed to know.
Super TechThe Magic of AMQ
Approximate membership queries are one of those quiet infrastructure ideas that feel like cheating until you realize the trick is restraint.
A working notebook from someone actually building the thing — the wins, the dead ends, and the receipts.
