Consh is a set of programs that can turn one or more UNIX hosts on a trusted LAN into a singular Bourne shell multi-computer on which shell scripts are run concurrently. The service abstracts hosts into what appears to be shell process with a fixed number of threads or workers, to which work may be assigned and results received concurrently. It includes utilities that assign commands to workers in parallel and a command that initiates distributed barriers between workers for synchronization purposes. Environment variables can be set on a per-host basis to implement locking mechanisms like semaphores or ticket algorithms. Daemons can delegate work to one another as needed.
tvpvrd is a PVR daemon for Linux that offers the ability to schedule and manage TV recordings using one or multiple installed analogue TV capture cards, e.g. Hauppauge. The daemon is interfaced either through its full command language via a provided command line shell or through a basic (built-in) Web interface provided by the built in micro Web server. The goal is to provide an advanced recording and transcoding (using ffmpeg) server without the need to configure databases or a complex GUI. The server is completely self-contained and uses an XML DB in plain text format to store future recordings.
