The GROMACS molecular simulation toolkit.

Ephemeral self-managed GitLab simulations on Google Compute Engine for LLM-mediated work.

Pyralysis is a Python library for radio interferometry: visibility simulation, gridding, optimization-based image reconstruction, and analysis pipelines with Dask-friendly scaling, documented APIs, and optional cluster (SLURM) workflows. GPL-3.0.

FlightGear open-source flight simulator flightgear.org

SimGear - simulation libraries for FlightGear

A simulator for our future-planned kernel, Nitrocid Kernel!

The project provides Python tool-chain and shell scripts for molecular simulation workflows: preparation, running and analysing molecular dynamics (MD) simulations of bio- and organic soft condensed matter.

Vendor-Independent, Fully Verified, Open Source VHDL Common Library

Library and graphical tools for running SPH and N-body simulations.

A set of services for military scenarios in FlightGear.

An edutainment game about running the mail, in the style of the late-'80s and early-'90s greats. Real USPS, census and labor data from 1900 on; portable C89 core for web, 68k Macintosh and more.

Python research code testing Prophet as a forecasting model. Includes random-walk and autocorrelation simulations, a hyperparameter tuning sweep, M4 hourly, weekly and daily benchmarks against naive, ETS, Theta and MSTL, and a rolling-origin evaluation on the Peyton Manning series.

R experiments behind the article "A Seed Is Not Reproducibility". The seed stays fixed while R's sampling rules, an extra random call, the locale, parallel workers, floating-point order or the data split change.

Python research code for the statistical power of text watermark detection. A token-level simulation of textGrain, green-list and Gumbel-max watermarks measures how detectability depends on passage length, entropy and edits, and tests what the published detection rates do and do not pin down.

Pyxel Config Lab is a visual YAML configuration builder and tutorial viewer created to help people explore Pyxel simulation modes through a more intuitive and interactive interface.

C blackjack engine + a 2014 experiment modeling family members' playing styles as simulated players.

Analysis of gene and allelic diversity in subdivided populations, as well as a tool for management in conservation programs.

Caasi is a lightweight, CLI-first orchestration layer for NVIDIA Isaac Sim, Isaac Lab and the wider robotics ecosystem (ROS 2, Nav2, MoveIt 2, ros2_control, …). It discovers the tools you already have, launches them headlessly, tracks every long-running process as a first-class run, and gives you uniform, scriptable output for all of it.
