The gnome-desktop set of libraries provides various utility functions that are used in multiple components of the GNOME desktop, but do not have a sufficiently stable API to be included in core libraries such as GLib and GTK.

McStas is a tool for carrying out Monte Carlo ray-tracing simulations of neutron scattering instruments with high complexity and precision. The simulations can compute all aspects of the performance of instruments and can thus be used to optimize the use of existing equipment, design new instrumentation, and carry out virtual experiments for e.g. training, experimental planning or data analysis.

Sydent is a reference implementation of the Matrix Identity Server API in Python, supporting:

GNAT is a compiler for the Ada programming language. It produces optimized code on platforms supported by the GNU Compiler Collection (GCC).
