The Shibboleth System is a standards based software package for web single sign-on across or within organizational boundaries. It supports authorization and attribute exchange using the OASIS SAML 2.0 protocol. Shibboleth allows sites to make informed authorization decisions for individual access of protected online resources while allowing users to establish their identities with their local authentication systems.

Plot density and distribution functions with automatic selection of suitable regions. Numerically invert (compute quantiles) distribution functions. Simulate real and complex numbers from distributions of their magnitude and arguments. Optionally, the magnitudes and/or arguments may be fixed in almost arbitrary ways. Create polynomials from roots given in Cartesian or polar form. Small programming utilities: check if an object is identical to NA, count positional arguments in a call, set intersection of more than two sets, check if an argument is unnamed, compute the graph of S4 classes in packages.

Silo is a library for reading and writing a wide variety of scientific data to binary, disk files.

GNU CLISP is a Common Lisp implementation. It conforms to the ANSI Common Lisp standard, and offers many extensions. It runs on all desktop operating systems (GNU and Unix systems, macOS, Windows) and is particularly memory-efficient.

libspatialaudio is an open-source and cross-platform C++ library for Ambisonic encoding and decoding, filtering and binaural rendering. It is targeted to render High-Order Ambisonic (HOA) and VR/3D audio samples in multiple environments, from headphones to classic loudspeakers. Its binaural rendering can be used for classical 5.1/7.1 spatial channels as well as Ambisonics inputs. It supports Higher Order Ambisonics (HOA) and ACN/SN3D Ambisonics audio streams following the Google spatial audio specification and the IETF codec Ambisonics specification.
