GNU Mach is the microkernel upon which a GNU Hurd system is based. It provides an Inter Process Communication (IPC) mechanism which the Hurd uses to define interfaces for implementing in a distributed multi-server fashion the services a traditional operating system kernel provides. Mach is particularly well-suited for SMP and network cluster techniques. Thread support is provided at the kernel level, and the kernel itself takes advantage of that. Network transparency at the IPC level makes resources of the system available across machine boundaries.
Libchop is a set of utilities and library for data backup and distributed storage. Its main application is chop-backup, an encrypted backup program that supports data integrity checks, versioning at little cost, distribution among several sites, selective sharing of stored data, adaptive compression, and more. The library itself, which chop-backup builds upon, implements storage techniques such as content-based addressing, content hash keys, Merkle trees, similarity detection, and lossless compression. It makes it easy to combine them in different ways. The ‘chop-archiver’ and ‘chop-block-server’ tools, illustrated in the manual, provide direct access to these facilities from the command line. It is written in C and has Guile (Scheme) bindings.
Ametys is a powerful Web CMS used by many institutions of higher education and government, but also industries and SMEs. It is known for its ergonomic design which promotes ease of use, its social Web functionality, and the ability to manage a large number of users. It makes content publishing accessible for the non-programmer and provides an easy editorial interface very similar to Microsoft Office applications.
Artha is a handy thesaurus based on WordNet with distinct features like global hot key look up, passive desktop notification, regular expression based search, etc. Artha may be used as a free open-source replacement/clone to the proprietary WordWeb Pro thesaurus (which is also based on WordNet) on Unix-like and Windows operating systems.
libneuro-java is a Java native interface to libneuro. It provides C++ and Java wrappers, as well as Java classes. It also provides control files to generate them from the libneuro interface using the program swig. The major and minor versions of this JNI will track that of libneuro, but its bugfixes are independent of libneuro bugfixes.
libalinga-java is a Java native interface to libalinga. It provides C++ and Java wrappers, as well as Java classes. It also provides control files to generate them from the libalinga interface using the program swig. The major and minor versions of this JNI will track that of libalinga, but its bugfixes are independent of libalinga bugfixes.
libalinga is a C++ implementation of a multi-stream codec for the ALingA (Aligned Linguistic Annotation) format. It makes use of libogg++. Each ALingA stream holds at least one stream of annotation data, which is in the LingA format. It may also interleave the signal stream(s) against which the LingA streams are aligned, or it may simply reference such streams. It also provides metadata about the underlying manifold for the signals and the annotations. The metadata is ordered for runtime parsing of the number and type of signal and LingA codecs to enable decoding of the multiple logical streams in one pass.
