Cock provides a digital version of a petcock. A petcock is a valve or faucet used to drain pressure, as from a boiler. Cock drains I/O pressure from the kernel. Without parameters, the output rate automatically adjusts; cock defers output when necessary in order to mitigate I/O spikes. Otherwise, a numeric parameter specifies megabytes per second.
losetup-utils are three bash scripts that attempt to make the use of losetup a bit easier and faster. losetup can be fast, easy, and practical if you need to transport sensitive information over the Internet or in CD's, DVD's, or a pendrive. Also, if you want to store private data on your hard disk or in the cloud, an encrypted volume can be a convenient choice. The types of encryption can be any installed on the system.
HOMER is a robust, carrier-grade, scalable SIP capturing system and monitoring application with hEP, IP Proto4 (IPIP) encapsulation, and port mirroring/monitoring support right out of the box, ready to process and store large amounts of signaling with instant searches, end-to-end analysis, and drill-down capabilities for ITSPs, VoIP providers, and trunk suppliers using SIP signaling.
Changing directories in bash can be tedious if you have long names or nested paths. Creating aliases or adding to the CDPATH can help, but can be improved on. Bashcd adds 6 new commands to make changing directories a bit easier. This commands use find, the locate database, the mdfind database, or other contextual information to make it easier to change to other directories.
Ybot is erlang bot software inspired by Github hubot. It supports IRC and XMPP transports and is extensible with plugins. Plugins can be written with Python, Ruby, or shell. It supports IRC chat, XMPP multi user chat, and 37 signals Campfire chat. It can simultaneously run any number of bots on different transports.
plumb is a shell with focus on pipes: instead of pipelines, it can build large graphs of processes (nodes) and pipes (edges). Pipes are simple unidirectional streams without side effects. Traffic can be controlled by virtual processes (which are nodes just like real processes, but are implemented in plumb for minimal overhead). Virtual processes can split, merge, regex filter/alter, and shape the streams. Timers and starting/stopping processes or even rewiring the script on the fly are also supported. It is portable (using libporty) and behaves exactly the same way on Linux, Windows, Mac OS X, many BSD variants, and older UNIX systems.
