pyrpm-manage manages signed packages, old releases and versions, and repositories. It is mainly there to help with cleaning up repositories full of many releases of the same package and then making an RPM repository usable with yum on RHEL-based distributions. It runs fairly well on Debian if you install RPM tools and python libraries.
OpenNetHome is a home automation software project with a focus on being able to mix different technologies. It currently supports a number of different RF transceivers for controlling remote switches and receiving temperature and moisture data. It also supports Philips Hue lights. Its user interface is Web based, but all features are also accessible via a TCP/IP interface. It supports plugins for new features but also for new protocol encoders/decoders. Also included is a signal analyzer tool for reverse engineering new RF protocols.
