The Network Time Protocol (NTP) is used to synchronize the time of a computer client or server to another server or reference time source, such as a radio or satellite receiver or modem. It provides client accuracies typically within a millisecond on LANs and up to a few tens of milliseconds on WANs relative to a primary server synchronized to Coordinated Universal Time (UTC) via a Global Positioning Service (GPS) receiver, for example.
skd is a small daemon which binds to a UDP, TCP, or Unix-domain socket, waits for connections and runs a specified program to handle them. It is ideal as a secure, efficient replacement for traditional inetd. It is also an easy-to-use tool for non-privileged users wanting to run their own network services. Datagram and stream sockets are available in both the Internet and Unix namespaces, each with the expected inetd behavior. In the Internet domain, IPv6 is supported in addition to IPv4. skd also supports connection limits, verbose logging of connections, dropping of privileges, forking into the background with a pidfile, and redirecting stderr to syslog or a file. Some of these facilities (such as forking into the background, privilege dropping, and logging) are also useful for standalone, non-network services and can be used without binding any socket.
Memventi is a Venti daemon. It speaks the same Venti protocol as the real Venti in Plan 9 from Bell Labs. It is a storage server that stores data blocks up to 56KB using its SHA-1 hash (called its score) to address it. It keeps a mapping of score to disk location in memory (in a memory-efficient manner). Blocks written cannot be removed, and blocks are only written once. Memventi writes new blocks to an append-only file, thereby making file corruption due to bugs practically impossible.
Multi Threaded Daemon - enhanced is a class that implements a daemon that can spawn multiple parallel threads. It includes a sample app to monitor a "queue" directory on the filesystem, and spawns up to "N" child processes to parse individual files from it. It is an enhanced version of the original Multithreaded Daemon class written by Benoit Perroud. This version provides several robustness improvements, adds support for handling signals (SIGTERM, SIGHUP), and a unique PID file to avoid starting multiple instances.
SwarmTv is a command line broad-catching program that downloads selected torrents/NZB's from an RSS or Twitter feed and puts them in a directory for your torrent program to download. The torrents to download are selected using filters that look at the name, size, and episode/season of the torrent. A mechanism is in place to prevent double downloads. Swarmtv can even send an email when a new episode is found.
A fully-featured launchd front-end for managing and debugging system and user services.
