libposix is an impementation of the core functionality of all Unix systems. It is a full, cross-platform implementation of the POSIX 2008 standard. It is meant to replace existing implementations of a Unix system's core libraries. It is an exact implementation of POSIX 2008 and nothing else (no extensions, no previous POSIX versions). However, it works well with possible extensions to the core system functionallity (for example, GNU or BSD).
Ductus is a wiki system designed to handle arbitrarily-structured content and a variety of workflows. With Ductus, programmers can easily define classes of structured content, providing rich mechanisms for user interaction. For instance, the Wikiotics project uses Ductus to allow people to collaborate on "language lessons," which can later be used as quizzes or flashcards. Such modes of interaction are not possible with most wikis, which are designed primarily to handle freely-structured text.
GNU Recutils is a set of tools and libraries to access human-editable text-based databases called recfiles. A recfile contains data structured as a sequence of records. The rec format supports data integrity with the usage of record descriptors (keys, mandatory fields, field types, etc.) as well as the ability of record fields to refer to other records. Despite its simplicity, recfiles can be used to store medium-sized databases. The GNU recutils suite comprises a texinfo manual describing the Rec format, a C library (librec) providing a rich set of functions to access rec files, a set of C utilities that can be used in shell scripts and in the command line to operate on rec files, and an Emacs mode (rec-mode).
GNU `tar' saves many files together into a single tape or disk archive, and can restore individual files from the archive. It includes multivolume support, the ability to archive sparse files, automatic archive compression/decompression, remote archives and special features that allow `tar' to be used for incremental and full backups. It also includes `rmt', the remote tape server (the `mt' tape drive control program is in GNU `cpio').
openmamba is a fully featured GNU/Linux distribution for desktops, notebooks, netbooks, and servers. It runs on computers based on the 32-bit Intel x86 architecture, or on 64-bit AMD processors in 32-bit mode. openmamba comes with both free and closed source drivers for the most frequently used video cards. It supports compiz out of the box. It has preinstalled multimedia codecs, and can install the most frequently used closed source applications for GNU/Linux (such as Flash Player or Skype) very easily.
