a parametric 3D CAD modeler
WARNING: FreeCAD has moved! FreeCAD code and release files are now hosted on github at https://github.com/FreeCAD/FreeCAD Only older files and code are available here. FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is 100% Open Source and extremely modular, allowing for very advanced extension and customization. FreeCAD is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. The interface is built with Qt. FreeCAD runs exactly the same way on Windows, Mac OSX and Linux platforms.
General Mission Analysis Tool
The General Mission Analysis Tool (GMAT) is an open-source tool for space mission design and navigation. GMAT is developed by a team of NASA, private industry, and public and private contributors. The GMAT development team is pleased to announce the release of GMAT version R2018a. New features in this release include orbit determination improvements, a built-in non-linear optimizer, and numerous bite-sized enhancements. For a complete list of new features, compatibility changes, and bug fixes, see the release notes contained in the user guide. In recent news, GMAT is now used operationally in support of the following missions: Solar Dynamics Observatory (SDO), Solar and Heliospheric Observatory (SOHO), the Advanced Composition Explorer (ACE), Wind, Transiting Exoplanet Survey Satellite (TESS) , and the Lunar Reconnaissance Orbiter (LRO).

A Smith charting program. You can enter either discrete components or transmission lines, see the results on screen and/or generate Postscript output. Component values can be changed numerically or using scrollbars.
A cross platform GUI for OBD-II interface device control. Currently supporting ELM327 devices, the app allows you to view and clear error codes, and view live data from the ECU. Packages available for Windows and Linux (deb or rpm)
Hotstop is scientific software that allows to extract experimental ion stopping force curves from RBS spectra (as well as to stimate uncertainities) It uses Simulated Annealing and Bayesian Inference algorithms.
Febrl (Freely Extensible Biomedical Record Linkage) does data standardisation (segmentation and cleaning) and probabilistic record linkage ("fuzzy" matching) of one or more files or data sources which do not share a unique record key or identifier.
A graphical interface for solving exterior ballistics problems, based on the excellent GNU exterior ballistics library. This software generates valid 3-DOF solutions to small arms trajectories, including wind and atmospheric corrections.
