SWISH++ is a Unix-based file indexing and searching engine (typically used to index and search files on web sites). It was based on SWISH-E although SWISH++ is a complete rewrite. SWISH++ is at least 10 times faster and can handle much larger numbers of files. Additionally, it has unique features such as selective non-indexing, on-the-fly filters, user-selectable stemming, and more.
CHSM is a language system for specifying concurrent, hierarchical, finite state machines (a realization of "statecharts") to model and control reactive systems. It uses its own statechart specification langauge annotated with either C++ or Java code fragments in the tradition of yacc grammars with C code fragments. The generated code is fully object-oriented allowing multiple state machines to exist concurrently. The run-time library is small, efficient, and thread-safe. It has been used successfully in production environments such as CERN for controlling high-energy physics experiment equipment.
