Incredible work! Do you have any plans to add sound effects synced to in-game events, or maybe even TTS-generated commentary? That could make the experience feel even more dynamic and immersive.

Awesome, great execution! This could become a really cool RL environment with a headless sim and procedural voyages. Factorio has something similar with the Factorio Learning Environment SDK.

Statically - basically just parsing the code into an AST and then walking through the tree to collect information about variable usage and definitions.

Very cool! looking forward to trying it out - the graphs reminded me of a toy project I'd done a while back to better understand deterministic and reproducible execution in python as seen in marimo notebooks https://github.com/vrtnis/python-notebook-simulator

yep, also i think while they could have issues with dataset sizes less than 2^k, it's interesting to note their use in accelerating clustering algos like dbscan. they do make neat visualizations though https://marimo.app/?slug=x5fa0x
Re:Show HN: A simple 2D fluid and gravity simulation with WASM and WebGL

while it's true that wasm was originally designed to run primarily on the cpu(e.g., executed in a sandboxed environment on the main thread, which is generally managed by the cpu), the assumption that wasm only runs on the cpu might be becoming a bit dated. esp. as a result of webgpu and frameworks mentioned above, wasm is increasingly capable of executing on the gpu imho.

Very cool..exciting to see you tackling the modular architecture challenge head-on, and also wrt to dynamically imported modules..would also be interesting to see some sort of IDE integration for real-time feedback directly in the development workflow. Would be nice to have a discord community around this!

Congrats on the launch! Couple of quick questions: Are there any initiatives or resources planned for educational institutions to adopt atopile? Outside of GitHub, are there specific areas or tasks where you’re seeking community or volunteer contributions? Thanks!

Actually, a few other cars had similar voice alert systems e.g., Mitsubishi and Oldsmobile.On the Oldsmobile the speech synthesis (Digitalker) was engineered by National Semiconductor. This page has more on it https://www.hagerty.com/media/car-profiles/talking-car-from-...

Table 19 from the paper seems to show pixel extraction accuracy is highest for AMD Radeon (94%) but lower for M1/M2 (~60%). Can't seem to find an explanation for this variation though. Thoughts?
