Working on reversing climate change. Carbon dioxide removal. Also getting curious about mechanisms to prevent damage from high temperatures in the short term. There's a project over the Great Barrier Reef I've been digging into what mechanisms they're using: https://barrierreef.org/news/explainers/what-is-cloud-bright...

How are you removing carbon dioxide?

Hosting an XGBoost-model for MLB totals predictions. It runs every thirty minutes: incorporating weather at the hyperlocal level and joins with player attributes that are provably affected by that weather. It also provides advanced decision-making tools with a Kelly Criterion calculator built in. Model still needs some calibration for bet-sizing but is very close to production-ready.

A boat game for 5+ age group! I was never much of a game developer, but recently my 5 year old son wanted to play a game so we decided to build one together. It's a boat game, you basically steer a boat in an isometric 2d world, transporting passengers, cargo etc between ports. As we designed it, the ideas just kept on coming. He made or directed a lot of the art inside of the game (even the audio), and we included f…

I'm super curious how you make the development process interesting for him. I get that a 5yo would be good at generating ideas but how do you then go "okay, now I'll need a week in front of a screen to build all these ideas" and not have him lose interest. Do you accelerate using LLMs?

My side project this quarter has been building a system that adds steering / planning to LLMs/WAMs/etc. (T, DiT, etc.) in a market/physics/other-ground-truth-constraints aware way. I have a small model outperforming some of the largest frontier models in some games (i.e., adversarial settings) now, but that is not very impressive because "plain old LLMs" are the wrong mathematical object for gameplay, IMO. So far, it's a mix of RL + optimization (e.g., MILP) on the planning side, and not quite realtime enough to play RTSes, but that's only a few weeks away. Have been very impressed at how far the open source ecosystem for this stuff has gotten since the last time I tried something like this.

I finished wiring up the backend data merge so user(s) (aka me, really) can record trees as they walk and have those merged into the general city data on my urban tree map app[1]. There's some very cool trees in the neighborhood I'm excited to have recorded.

Which leads me to trying to get the processing off github actions (it's all duckdb pipelines), which has led me to improve the orchestration implementation of my 'better sql' [2] to optimize the asset based refresh flow. I'm now wiring that up in a general cloud service to give me the data orchestration platform I've always wanted. Building a multi-tenant cloud experience has been interesting!
