SQLet allows you to directly execute SQL on multiple text files, right from the Linux commandline. In one single command, you can read in text files (with or without header lines) and perform arbitrary select statements, including joins over several files. SQLet can thus replace awk or grep in some instances.
Collage is a cross-platform C++ library for building heterogenous, distributed applications. Among other things, it is the cluster backend for the Equalizer parallel rendering framework. It provides an abstraction of different network connections, peer-to-peer messaging, node discovery, synchronization, and high-performance, object-oriented, versioned data distribution. It is designed for low-overhead multi-threaded execution, which allows applications to easily exploit multi-core architectures.
AeonWave Audio-FX is real-time, hardware accelerated, cross platform audio effects software for guitar players, singers, vocalists, voice overs, or DJs. Originally designed as an audio effects applet for instrumentalists, it now extends to areas like voice processing for vocalists or live or podcasting DJ work. Effects include Compressor, Phaser, Flanger or Chorus, Wah, Distortion, and Reverb with echo.
LMDB is an ultra-fast, ultra-compact key-value data store developed by Symas for the OpenLDAP Project. It uses memory-mapped files, so it has the read performance of a pure in-memory database while still offering the persistence of standard disk-based databases, and is only limited to the size of the virtual address space (it is not limited to the size of physical RAM).
BBCT is a simple database app for your baseball card collection. You can add information about the cards in your collection, view details about individual cards, and filter the list of cards according to a limited set of criteria. BBCT helps you organize your collection and quickly look up which cards you own.
libnode is a C++ implementation of Node.js. Just like Node.js, libnode provides non-blocking I/O, which enables you to develop scalable Web applications in C++. The memory management of libnode is automatic, based on either shared_ptr or bdw-gc. libnode is good to use on embedded devices because its system resource consumption is lower than Node.js.
