Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

We built the city of Colombo in Cities:Skylines
This is super impressive! I'd agree the open-source tooling isn't there yet, but it's coming in a few places. I started a 3D street visualizer but it's only at the scope of a few blocks at a time, not as large as a city area although we'd like to get there someday: https://github.com/3dstreet/3dstreet/
There's also https://github.com/a-b-street/abstreet for larger area simulation but with less visual fidelity

Show HN: I built a transit travel time map
Super awesome! I like how you just color roads to show time. When you calculate polygons to try and cover the whole area in some 5-10 minute bucket, you can wind up with all sorts of odd holes far away from roads. Keep it simple.

Not a Surprise: 101 Freeway Widening Shows Negative Results
You can build it out in a cool simulator and show it off.

Bay Area drivers spend 97 hours a year in traffic. Why didn’t remote work end commute nightmares?
The tool you want exists, but you'll need to actually build the city in it. It's really an incredible program!

Why hasn't there been more of an effort to create an open source network of weather stations?
WRF-ARW Modeling System is in the public domain and there is a fork called WRFg that can utilize GPU acceleration. The price of used Nvidia tesla GPUs could allow an enthusiast group to band together and thrive however that doesn't solve the sheer complexity of using the model and obtaining enough accurate data points to even run the model.

What amount of weather forecasting modelling is open source?
The NAM, RAP, and HRRR are all different smaller-scale, higher-resolution models for the US and North America based on the Weather Research and Forecasting model. These are due to eventually be replaced by the RRFS, based on the UFS Short-Range Weather Application.

Why C?
Hi, I'm going to nitpick and say that most physics modeling software is not written in C. A whole bunch of physics programs are in Fortran (like weather models) .

GPUs open the potential to forecast urban weather for drones and air taxis
For some context, WRF (https://github.com/wrf-model/WRF) the current state-of-the-art weather modeling system (also developed by NCAR) can only run on CPU. There have been efforts to run it on GPU (https://wrfg.net)... though it doesn't look like it's been kept up to date.
It seems like FastEddy mostly replaces WRF-LES, which is used for high-resolution localized modeling.

Does anyone know of any self hosted weather prediction software?
Most of the weather models run on supercomputers, and require a LOT of input data. Here’s one you can try if you’re so inclined. https://github.com/wrf-model/WRF
