SLEEF (SIMD Library for Evaluating Elementary Functions) is a library that facilitates programming with SIMD instructions. It implements the trigonometric functions, inverse trigonometric functions, exponential and logarithmic functions in double precision without table look-ups, scattering from, or gathering into SIMD registers, or conditional branches. This library also includes some functions for evaluation in single precision.
Moosic is a music player that focuses on easy playlist management. It consists of a server process that maintains a queue of music files to play and a client program which sends commands to the server. The server continually runs through its playlist, popping items off the top of the list and playing each with an external program. The client is a simple command-line utility which allows you to perform powerful operations upon the server's queue, including the addition of whole directory trees, automatic shuffling, and item removal according to regular expressions. The server comes configured to play MP3, Ogg, MIDI, MOD, and WAV files.
libjio is a C library to do journaled, transaction-oriented I/O. It provides a UNIX-like set of file operation functions (such as open, read, and write), which are wrapped in a transaction framework, so that file operations can be committed or rolled back as necessary. It is non-intrusive, atomic, and thread-safe, with fast crash recovery.
Werc is a minimalistic RESTful Web application framework and content management system. It follows the Unix "tool philosophy" and it is designed to be fast, simple, convenient, and easily extensible. It handles both small and big sites and has a flexible system for user and group permissions. All data is stored in plain text files that can be easily manipulated with standard tools, without using any databases or other external dependencies. Existing applications include a blogging engine with RSS/Atom feeds, a wiki system that can easily integrate pre-existing documents (can be enabled for any directory tree), and others.
