Figure I'd drop this here - some other projects I'm working on currently:

Seafloor LOD (infinite terrain generator): https://github.com/kanakawai-maui/seafloor-lod

Olelo Honua (free LLM-enabled translation tool): https://www.olelohonua.com/

I just pushed an update using spalart-allmaras turbulence model (somewhere in between NS and panel methods). Also updated the controls to use arrow keys :)

rbrownmhon Ask HN: What are you working on? (April 2025)

Aside from my main project, ʻŌlelo Honua, I'm working on an air/hydro foil simulation (just for fun). Currently using rudimentary physics and in it's early stages. Would like to add more particles and incorporate Navier-Stokes equations.

rbrownmhon Ask HN: What's the best way to get started with LLM-assisted programing?

I would highly recommend starting w/ OpenRouter - it's easy to play around w/ free models and their documentation is great.

OpenRouter Quickstart: https://openrouter.ai/docs/quickstart

See usage example here (Typescript): https://github.com/brownrw8/olelo-honua/blob/main/src/provid...

And while you're at it, check out my open source project using OpenRouter, ʻŌlelo Honua ;)

rbrownmhon Ask HN: What are you working on? (March 2025)

Working on ʻŌlelo Honua, a free and open-source internationalization (i18n) tool that uses AI to translate app content. Now building a CLI so it can integrate seamlessly with tools like Shopify and other platforms. The goal is to make localization effortless for developers without relying on expensive translation services.

Would love feedback—especially on CLI features you'd find useful!

I'd love to know the opportunity cost - billions?

> "Passenger planes with speed beyond Mach four" and "superconductive magnetic levitation railways at 500 km/h" probably seemed like reasonable extrapolations of current trends at the time.

I'm a bit upset we can't have this today.
