fretscpp is strongly inspired by the original FoF, reusing artwork to a large extent, with the source code rewritten from scratch. C++ instead of python should improve performance and allow easier support for features like whammy. It is playable, but some non-critical features are still missing.
iSAM is an optimization library for sparse nonlinear problems as encountered in simultaneous localization and mapping (SLAM) in mobile robotics. The iSAM library provides efficient algorithms for batch and incremental optimization, recovering the exact least-squares solution. The library can easily be extended to new problems, and functionality for often encountered 2D and 3D SLAM problems is already provided.
Apache Qpid is a messaging broker that implements the latest AMQP specification, providing transaction management, queuing, distribution, security, management, clustering, federation, heterogeneous multi-platform support, and much more. It is extremely fast and aims to be 100% AMQP Compliant.
The j661 project provides a generic CDS (or ARINC 661 Server) in order to facilitate the understanding of the ARINC 661 standard, prototype ARINC 661 concepts and architectures, and facilitate the reuse of ARINC 661 specifications and artefacts between projects. The CDS architecture is designed to allow defining the Server behavior to be easily modified or extended. This is achieved by a modular plug-in architecture, allowing customization at runtime without changing anything in the Server core itself.
OwfsWeather is a package that scans and logs weather data from various One-Wire weather sensors. It uses OWFS, the One Wire File System, to communicate with the sensors. It currently supports logging of weather data to Weather Underground, a CSV file, and to an RRD database. Current hardware supported is the WSI-601 weather station from AAG, a DS1820 temperature sensor, and the humidity and barometric pressure modules from Hobby Boards.
