Libdmapsharing is a library you may use to access, share, and control the playback of media content using DMAP (DAAP, DPAP, & DACP). Libdmapsharing also detects audio AirPlay services; coupled with the AirPlay support in PulseAudio or GStreamer, this can allow an application to stream audio to an AirPlay device. The library presently supports Linux and other POSIX-based systems. It is written in C using GObject and libsoup. The DMAP family of protocols are used by products such as Apple iTunes, Apple iPhoto, and the Roku SoundBridge family to share media such as music and photos.
Subsurface is a dive log program. The user can download dive information directly from a large number of supported dive computers. Subsurface is able to track multi-tank dives with air, Nitrox, or TriMix, weights and exposure protection used, dive masters, and dive buddies, and allows the user to rate dives and provide additional dive notes. It calculates a wide variety of statistics of the user’s diving and calculates and tracks information like SAC rate or OTU. Subsurface allows the user to print out a detailed log book including dive profiles and other relevant information.
