SUN-EARTH-MOON SYSTEM VISUALIZER
My kids keep asking the same two questions, and both are weirdly hard to answer with words: why is it always the same face of the Moon we see, and how can the Sun and Moon be up at the same time? So I built a thing you can poke at instead. It's the rolling-coin analogy made interactive -- a tidally-locked Moon you can unlock, real moon phases, and an observer's sky that shows exactly when both the Sun and Moon clear the horizon. Periods and phase geometry are faithful; distances are honestly not to scale.
SOLAR SYSTEM
Ever wonder where Neptune is right now? This uses real orbital data from NASA's JPL Horizons system to render an accurate snapshot of the solar system on any date from 1996 to 2025. Check your birthday, watch the planets race each other in timelapse, or filter down to just the moons. It's the solar system, to scale, in your browser.
SATURN V ASCII LAUNCH
Started because I wanted a rocket launch playing every time I opened my terminal. A fastfetch splash screen turned into a full truecolor ASCII rendering engine -- the Apollo 11 liftoff, frame by frame, with real flame physics and smoke that dissipates top-to-bottom. The full NASA footage streams as 2MB chunks of colored characters. Rocket launches every time you open your terminal -- see the repo for install instructions.
PERSISTENT MEMORY FOR LLM AGENTS
LLM agents forget everything between sessions. This system models memory as scored beliefs with Bayesian confidence tracking, detects corrections without LLM calls (92% accuracy), and bridges vocabulary gaps in retrieval (99.5% recovery). No embeddings anywhere -- FTS5 keyword search plus typed knowledge graphs. 98 experiments, 35 case studies, 5 benchmarks with the re-runs published even where they came back lower. Now at v4.0: temporal-spine retrieval (+14.6pp coverage on fresh LoCoMo), junk demotion, and 6,009 tests.
DIFFERENTIABLE ROCKET SCIENCE
In 2021 I tried to train an RL agent to fly to the Moon for a grad astrodynamics course, and it never learned a thing. In 2026 I went back, found the real bugs, and rebuilt it on a better idea: backpropagate the fuel bill through the physics itself. The result circularizes 92.3% of random orbits at 1.03x the analytic-optimal fuel, rediscovers a real operational J2 maneuver from the raw objective, and pulls off a verified ballistic lunar capture with no capture burn. The 2021 failure ships in the repo, unmodified.
MINING SATURN'S RINGS
The mission concept carries multi-tonne chunks of 99.7-percent-pure water ice out of Saturn's B ring to Earth orbit. The cargo is also the propellant supply for the return leg. I ran 215 pre-registered analysis rounds to falsify the concept. The rounds falsified it. Under closed-loop mass accounting, zero of 1,744 mission paths complete the round trip. The one corridor that remains needs three unproven technologies together. The financial model gives a water price three times higher than the best defensible market price. The repository contains the retractions together with the claims.
