furious_tv is a PVR backend that uses an SQLite database to hold XMLTV listings data. Using that data, it can automatically execute commands to record TV shows off of a capture device (multiple capture devices are supported). If Shuriken is installed, furious_tv can also automatically power the system on/off for recordings to save power.
updyn is a shell script that updates a dynamic DNS service with the current IP address. It will work with any dynamic DNS service that allows you to call a URL to update the DNS. It works behind a router when an external IP address is different from internal IP, optional minimum time check, does not update unless your actual IP is different from your assigned IP, and can be set to update the DNS every set number of days whether or not your IP has changed.
